############################## [2014-07-09] ############################## [22:48:55] ylluminate(@ylluminate):so that on-the-fly approach would leverage nodejs runner? ---------------------------------------------------------------------------------------------------- [22:49:04] Elia Schito(@elia):https://github.com/opal/opal/blob/master/stdlib/nodejs/require.rb ---------------------------------------------------------------------------------------------------- [22:50:14] Elia Schito(@elia):yep, the nodejs runner will need to require stuff at runtime (e.g. in `bin/opal -e 'puts 5’`) ---------------------------------------------------------------------------------------------------- [22:55:42] ylluminate(@ylluminate):hmm, so walk me through this mentally here. what roughly, in an outline, would need to be done to allow requires to operate on the fly in browser? ---------------------------------------------------------------------------------------------------- [22:56:59] Elia Schito(@elia):oh, wait, isn’t `require_remote` enough for that? ---------------------------------------------------------------------------------------------------- [22:57:14] Elia Schito(@elia):https://github.com/opal/opal/blob/master/stdlib/opal-parser.rb#L11-L18 ---------------------------------------------------------------------------------------------------- [22:57:19] ylluminate(@ylluminate):oh, wait... what's that? i've not looked into that ---------------------------------------------------------------------------------------------------- [22:58:33] Elia Schito(@elia):when you require opal-parser `require_remote` is added to Kernel ---------------------------------------------------------------------------------------------------- [22:58:38] Elia Schito(@elia):and takes a URL ---------------------------------------------------------------------------------------------------- [22:58:54] Elia Schito(@elia):that will be loaded via (A)JAX (synchronously) ---------------------------------------------------------------------------------------------------- [22:59:21] ylluminate(@ylluminate):interesting, then that's essentially the same thing; seems as though that if running in browser require could be an alias of require_remote with a little setup ---------------------------------------------------------------------------------------------------- [22:59:50] ylluminate(@ylluminate):so you could effectively say `require_remote "rb/my_include.rb"` to get an rb file from within the rb subfolder of the site ---------------------------------------------------------------------------------------------------- [23:01:14] Elia Schito(@elia):yes a custom require implementation with a base url + cdn fallback should work ---------------------------------------------------------------------------------------------------- [23:01:22] Elia Schito(@elia):and no MRI server ---------------------------------------------------------------------------------------------------- [23:03:39] ylluminate(@ylluminate):slick, require_remote worked a treat it appears for him ---------------------------------------------------------------------------------------------------- [23:04:39] Elia Schito(@elia):…which reminds me how much we need documentation ---------------------------------------------------------------------------------------------------- [23:04:53] ylluminate(@ylluminate):indeed ---------------------------------------------------------------------------------------------------- [23:06:07] ylluminate(@ylluminate):but yes, if we can add a little logic to use require_remote when in a non mri env, then this would be great and would preclude the need to tell ppl this, thus minimizing documentation on this aspect ---------------------------------------------------------------------------------------------------- [23:07:34] ylluminate(@ylluminate):it's silly that just such a simple thing caused such a head->wall bashing for so long earlier for him. ---------------------------------------------------------------------------------------------------- [23:07:40] Elia Schito(@elia):yeah, but it should be opt-in b/c ppl buiding in MRI single file via Opal::Builder ---------------------------------------------------------------------------------------------------- [23:08:05] Elia Schito(@elia):builder will coiplaint if it can’t find a file ---------------------------------------------------------------------------------------------------- [23:08:30] ylluminate(@ylluminate):well, can't we add an env test? crudely: if mri/builder, use std require; else use require_remote ---------------------------------------------------------------------------------------------------- [23:09:01] Elia Schito(@elia):> …such a simple thing… plz turn the pain into docs! ---------------------------------------------------------------------------------------------------- [23:09:23] ylluminate(@ylluminate):or vice-versa: if cdn, use require_remote, else just good old require ---------------------------------------------------------------------------------------------------- [23:09:34] ylluminate(@ylluminate):i imagine the latter is easier to test ---------------------------------------------------------------------------------------------------- [23:09:54] ylluminate(@ylluminate):lol ---------------------------------------------------------------------------------------------------- [23:09:55] Elia Schito(@elia):Need a code example to fully understand I guess ---------------------------------------------------------------------------------------------------- [23:10:38] ylluminate(@ylluminate):k, i will ponder on this as i get some time ---------------------------------------------------------------------------------------------------- [14:00:29] Elia Schito(@elia):@wstucco ``` def a(b=1,$options = undefined) c = $options.to_hash.fetch(:c, 2) p [b,options] end ``` ---------------------------------------------------------------------------------------------------- [19:30:07] ylluminate(@ylluminate):hey @elia @adambeynon we're going to work on throwing together a more automated update of the opal cdn mechanism if that's okay with you guys. we were thinking about putting a task into the rakefile to update it and then running it on one of our servers to check it out and to also update the main cdn page to show a listing of files as per: https://github.com/opal/opal-cdn/issues/1 -- of course we'd like to add in opal-jquery, opal-browser and any thing else from opal org that you'd like to pop in. ---------------------------------------------------------------------------------------------------- [19:31:24] ylluminate(@ylluminate):we are planning on throwing it onto one of our servers as a scheduled task that runs every X hours to make sure that master is updated and hopefully we can figure out a way to watch for version bumps keep `current` up-to-date as well ---------------------------------------------------------------------------------------------------- [19:31:33] ylluminate(@ylluminate):(on the cdn) ---------------------------------------------------------------------------------------------------- [22:36:48] Elia Schito(@elia):> re: require. i thought you'd implemented that in master such that we can require other .rb files within .rb scripts @ylluminate I did, but I don’t see how they can be useful for the cdn… ---------------------------------------------------------------------------------------------------- [22:39:03] ylluminate(@ylluminate):it's very useful for creating multi file projects. for example, my son is making a tutorial game in opal that is separated out into multiple files in js via require.js ---------------------------------------------------------------------------------------------------- [22:39:42] ylluminate(@ylluminate):he wants to likewise be able to use simple ruby requires the same way within this opal version so that he can demonstrate the power of using opal in browser as an introduction to folks ---------------------------------------------------------------------------------------------------- [22:40:23] ylluminate(@ylluminate):he is planning on creating several opal tutorials in this fashion and is loath to just embed it all within a singular file or even to include it via js includes in the html ---------------------------------------------------------------------------------------------------- [22:44:20] ylluminate(@ylluminate):@elia does that not make sense? ---------------------------------------------------------------------------------------------------- [22:44:45] Elia Schito(@elia):sorry, watching the world cup in the meanwhile :soccer: ---------------------------------------------------------------------------------------------------- [22:44:53] ylluminate(@ylluminate):lol ---------------------------------------------------------------------------------------------------- [22:47:43] Elia Schito(@elia):k, well, the require stuff is oriented to precompilation ---------------------------------------------------------------------------------------------------- [22:48:11] Elia Schito(@elia):but there’s already some support for the nodejs runner ---------------------------------------------------------------------------------------------------- [22:48:15] ylluminate(@ylluminate):do you have an idea of how to make it work as well for this scenario? ---------------------------------------------------------------------------------------------------- ############################## [2014-07-19] ############################## [10:55:41] Elia Schito(@elia):@ylluminate `https://gist.github.com/elia/0c12c3d7529e042a1503` ---------------------------------------------------------------------------------------------------- [10:57:25] Elia Schito(@elia):to generate it I did the following: ```bash gem install opal-browser --pre opal-build -ropal/browser -oopal-browser.js browser ``` ---------------------------------------------------------------------------------------------------- [13:35:02] Elia Schito(@elia):hey @adambeynon! ---------------------------------------------------------------------------------------------------- [17:26:07] ylluminate(@ylluminate):@elia thanks so much for looking into that. Unfortunately the resultant file is around 325k, which is like the opal-jquery result where it included opal proper as well. why is the previous syntax that worked for `opal-jquery` not working: `opal-build -r opal-browser -o opal-browser.js -- opal-browser` ---------------------------------------------------------------------------------------------------- [18:23:59] Elia Schito(@elia):@ylluminate the gist seems fine, the reason `opal-build -r opal-browser -o opal-browser.js -- opal-browser` doesn’t work is b/c in opal-land opal browser is named browser and after `--` you should put the opal lib you want to build ---------------------------------------------------------------------------------------------------- [18:24:28] Elia Schito(@elia):https://github.com/opal/opal-browser/tree/master/opal ---------------------------------------------------------------------------------------------------- [19:18:46] ylluminate(@ylluminate):@elia okay, gotcha, thanks. The size was worrying me since jquery was considerably smaller and I was fearful, without examining it, that opal proper was being included as with jquery when we were discussing it before. ---------------------------------------------------------------------------------------------------- ############################## [2014-07-21] ############################## [20:01:07] ylluminate(@ylluminate):@elia i'm curious, really great to see that you added some external lib support and documentation to opal-cdn. but, on the curiosity front, it appears that you added them to here: https://github.com/opal/opal-cdn/tree/gh-pages/external/0.6.2 -- why not have a `master` folder that these are in to support the accompanying `master` branch and then have them tagged also to support versions? will this present a compatibility problem when pulling opal from `master` vs `current`? ---------------------------------------------------------------------------------------------------- [20:01:58] ylluminate(@ylluminate):further, should this also not contain a `.min.js` and a `.min.js.gz` like unto the other primary opal libs within https://github.com/opal/opal-cdn/tree/gh-pages/opal/? ---------------------------------------------------------------------------------------------------- [21:25:21] Elia Schito(@elia):@ylluminate you’re right on every front, that was a kind of experiment done in spare time ---------------------------------------------------------------------------------------------------- [21:26:36] Elia Schito(@elia):A better and automatic workflow is necessary to have all that stuff and keep it up-to-date ---------------------------------------------------------------------------------------------------- [21:27:59] Elia Schito(@elia):also there’s another issue, currently the bower package for opal points to the cdn repo which ideally contains historical builds and version which is –at least– suboptimal ---------------------------------------------------------------------------------------------------- [23:37:27] ylluminate(@ylluminate):gotcha, thanks. wasn't sure your intention there ---------------------------------------------------------------------------------------------------- ############################## [2014-07-25] ############################## [10:37:44] Elia Schito(@elia):@wstucco ``` >> def a(b,c,*d,**e,&f);end; ?> method(:a) => # >> method(:a).parameters => [[:req, :b], [:req, :c], [:rest, :d], [:keyrest, :e], [:block, :f]] >> ``` ---------------------------------------------------------------------------------------------------- ############################## [2014-08-02] ############################## [16:51:17] Elia Schito(@elia):@meh welcome :panda_face: ---------------------------------------------------------------------------------------------------- [16:51:22] meh.(@meh):fico ---------------------------------------------------------------------------------------------------- ############################## [2014-08-05] ############################## [16:28:03] Ryan Stout(@ryanstout):@elia so is the glitter room separate from irc or the same? ---------------------------------------------------------------------------------------------------- [16:38:34] Elia Schito(@elia):@ryanstout it has irc access (via irc.gitter.im) but it’s a separate thing from freenode ---------------------------------------------------------------------------------------------------- [16:42:58] Elia Schito(@elia):@ryanstout the real value though resides in its deep integration with github ---------------------------------------------------------------------------------------------------- [16:43:23] Ryan Stout(@ryanstout):yea, it looks cool. Having GHFM is really nice. ---------------------------------------------------------------------------------------------------- [16:46:01] Elia Schito(@elia):and also off-line notifications and read confirmations are great ---------------------------------------------------------------------------------------------------- [17:32:45] ylluminate(@ylluminate):agreed on all counts. i kinda think this is a nice replacement for irc in such cases ---------------------------------------------------------------------------------------------------- [17:38:43] Elia Schito(@elia):and there’s always https://irc.gitter.im :smirk: ---------------------------------------------------------------------------------------------------- ############################## [2014-08-11] ############################## [09:19:35] Elia Schito(@elia):If anyone’s interested I published corelib docs to http://opal.github.io/opal/doc/opal/frames.html#!file.README.html ---------------------------------------------------------------------------------------------------- [09:20:29] Elia Schito(@elia):The idea is to have a service similar to rdoc.info but for opal-land ---------------------------------------------------------------------------------------------------- [14:03:21] Bernhard Weichel(@bwl21):@elia wrt to http://stackoverflow.com/questions/25233095/how-can-i-store-retrieve-files-in-owncloud-from-a-webapp-written-in-opal-ruby ---------------------------------------------------------------------------------------------------- [14:04:02] Bernhard Weichel(@bwl21):opal.org/try/# uses 0.6.2 and seems to return promises ... ---------------------------------------------------------------------------------------------------- [14:04:24] Elia Schito(@elia):@bwl21 yes, opalrb.org/try should be more up to date ---------------------------------------------------------------------------------------------------- [14:04:28] Bernhard Weichel(@bwl21):@elia but at the moment I cannot solve the authentication issue. ---------------------------------------------------------------------------------------------------- [14:04:47] Elia Schito(@elia):so, which versions are you using in your code? ---------------------------------------------------------------------------------------------------- [14:04:57] Bernhard Weichel(@bwl21):my code runs 0.6.2 ---------------------------------------------------------------------------------------------------- [14:05:13] Elia Schito(@elia):opal-jquery version?

---------------------------------------------------------------------------------------------------- [14:06:22] Elia Schito(@elia):right ---------------------------------------------------------------------------------------------------- [14:06:36] Elia Schito(@elia):opal-browser has its implementation with different API ---------------------------------------------------------------------------------------------------- [14:07:11] Bernhard Weichel(@bwl21):HTTP.get("https://cloud.weichel21.de:61670/remote.php/webdav/", {username:"fooname", password:"foopass", } ).then do |response| puts "success" puts response.body end.fail do |response| puts "fail" puts response.status_code end puts "foo" ---------------------------------------------------------------------------------------------------- [14:07:36] Bernhard Weichel(@bwl21):result is always foo fail 401 ---------------------------------------------------------------------------------------------------- [14:08:04] Elia Schito(@elia):To have promises you need to get opal-jquery from git I think ---------------------------------------------------------------------------------------------------- [14:08:05] Bernhard Weichel(@bwl21):even if I provide the correct username password (here in the chat I did not post the same :-) ---------------------------------------------------------------------------------------------------- [14:08:33] Bernhard Weichel(@bwl21):I am just playing around in opal.org/try ---------------------------------------------------------------------------------------------------- [14:08:37] Elia Schito(@elia):wrt the auth problem could be plain bug, have you checked the request headers?

It is awesome!!! ---------------------------------------------------------------------------------------------------- ############################## [2014-10-01] ############################## [08:17:40] Elia Schito(@elia)::star: ---------------------------------------------------------------------------------------------------- [15:09:50] George(@georgeu2000):Regarding the purpose of Opal, do you have any notes about that? The more I work with it, the more I see that Ruby and JS are different. So it feels weird to write Ruby just to avoid writing JS. ---------------------------------------------------------------------------------------------------- [15:11:24] George(@georgeu2000):I wonder if there are other goals, such as making the server and browser one system, instead of 2 separate systems? ---------------------------------------------------------------------------------------------------- [16:45:47] Elia Schito(@elia):@georgeu2000 for me it’s about having all the features that make Ruby great instead of all the “bad parts” of javascript. But I see that the more you interact with other JS libs the more you’ll experience the gap between the two languages… ---------------------------------------------------------------------------------------------------- [17:20:46] George(@georgeu2000):Do you have any specific use cases? For example, sharing code between server and browser? ---------------------------------------------------------------------------------------------------- [17:21:46] Elia Schito(@elia):Did happen a couple of times that I moved code from one to the other with little or no modification ---------------------------------------------------------------------------------------------------- [17:51:32] George(@georgeu2000):Is it possible to take HTML string and create HTML objects, operate on them using Opal-jQuery, and then append to the DOM? For example: html = "
bar
" ---------------------------------------------------------------------------------------------------- [17:53:30] George(@georgeu2000):Here's my use case: Browser get JSON from the server, and has the html template (as above). ---------------------------------------------------------------------------------------------------- [17:54:20] George(@georgeu2000):I want to add the JSON data to the html, and then append it to the DOM. ---------------------------------------------------------------------------------------------------- [18:10:46] Elia Schito(@elia):gotta go, will reply later ---------------------------------------------------------------------------------------------------- [23:00:21] Elia Schito(@elia):@georgeu2000 sure, with opal-jquery you can do everything you can do with normal jquery ---------------------------------------------------------------------------------------------------- ############################## [2014-10-02] ############################## [14:53:41] George(@georgeu2000):@edubkendo - I see. ---------------------------------------------------------------------------------------------------- [14:55:32] Adam Beynon(@adambeynon):georgeu2000 - In relation to your sharing code question, I share quite a few "model validator" classes between the server and client, and that works really nicely. Both also use rspec for tests, so running those in the client as well is really reassuring ---------------------------------------------------------------------------------------------------- [14:55:57] Adam Beynon(@adambeynon):apart from that, the backend is just serving up JSON, and then the client uses Vienna::View for rendering the HAML templates ---------------------------------------------------------------------------------------------------- [15:17:41] George(@georgeu2000):@adambeynon - Cool. Do you write your own "model validator" classes? ---------------------------------------------------------------------------------------------------- [15:18:09] Elia Schito(@elia):@adambeynon please paste here one of them (or in a gist) I’m interested too :) ---------------------------------------------------------------------------------------------------- [15:18:28] George(@georgeu2000):Or use AR or other DB validators? ---------------------------------------------------------------------------------------------------- [15:21:38] Adam Beynon(@adambeynon):They used to be AR validations, but I extracted them because I also wanted them client side ---------------------------------------------------------------------------------------------------- [15:21:53] Adam Beynon(@adambeynon):e.g. the one Im working to refactor now just validates dates for a Holiday Reservation ---------------------------------------------------------------------------------------------------- [15:22:05] Adam Beynon(@adambeynon):so, I just implement them as simple Ruby classes.. ---------------------------------------------------------------------------------------------------- [15:22:15] Adam Beynon(@adambeynon):and for Rails, add them inside a before_update call ---------------------------------------------------------------------------------------------------- [15:22:23] Adam Beynon(@adambeynon):and for vienna, I have similar callback features ---------------------------------------------------------------------------------------------------- [15:22:36] Adam Beynon(@adambeynon):(I dont like packing everything inside the model implementation as much as I can) ---------------------------------------------------------------------------------------------------- [15:24:10] Elia Schito(@elia):extracting validations makes much sense, especially considering different context (same as what happened with strong parameters) ---------------------------------------------------------------------------------------------------- [15:25:39] Adam Beynon(@adambeynon):agreed. One thing I've also really got into recently is the Interactor pattern with rails controllers ---------------------------------------------------------------------------------------------------- [15:25:42] Adam Beynon(@adambeynon):gem I use: https://github.com/collectiveidea/interactor ---------------------------------------------------------------------------------------------------- [15:25:49] Adam Beynon(@adambeynon):converted most controllers to use that ---------------------------------------------------------------------------------------------------- [15:25:59] Adam Beynon(@adambeynon):so controller testing now is pretty much zero ---------------------------------------------------------------------------------------------------- [15:26:11] Adam Beynon(@adambeynon):even PORO make more sense ---------------------------------------------------------------------------------------------------- [20:03:47] George(@georgeu2000):How can I tell if the code is running in Javascript? ---------------------------------------------------------------------------------------------------- [20:04:17] George(@georgeu2000):Is there a var or method that exposes the environment? ---------------------------------------------------------------------------------------------------- [20:18:22] Adam Beynon(@adambeynon):RUBY_ENGINE == "opal" ---------------------------------------------------------------------------------------------------- [21:14:59] Elia Schito(@elia):@adambeynon interactor looks good, but I’d like to see one of the validators ---------------------------------------------------------------------------------------------------- [21:21:33] Adam Beynon(@adambeynon):elia: well, the one Im about to start rewriting: https://gist.github.com/adambeynon/dd86f787f53e0a878f40 ---------------------------------------------------------------------------------------------------- [21:22:45] Adam Beynon(@adambeynon):that doesnt currently work under opal/vienna... ---------------------------------------------------------------------------------------------------- [21:22:56] Adam Beynon(@adambeynon):its also quite tricky to make work under both :( ---------------------------------------------------------------------------------------------------- [21:23:05] Elia Schito(@elia):thanks, I was curious about error handling / storage ---------------------------------------------------------------------------------------------------- [21:23:25] Elia Schito(@elia):dates uh?

Yea, now its (almost) any ruby in between {{ ... }} ---------------------------------------------------------------------------------------------------- [22:18:19] Loïc Boutet(@loicboutet):do you see what I mean? ---------------------------------------------------------------------------------------------------- [22:18:32] Loïc Boutet(@loicboutet):ok sounds good ! ---------------------------------------------------------------------------------------------------- [22:21:31] Loïc Boutet(@loicboutet):I'm quite excited at opal and the project building on top of it ---------------------------------------------------------------------------------------------------- [22:22:03] Loïc Boutet(@loicboutet):I feel like rails did not catch up to the new development of single app page and hope ruby in general will be able to catch up ---------------------------------------------------------------------------------------------------- [22:22:17] Loïc Boutet(@loicboutet):I'm glad to see new stuff like volt proposing solutions :) ---------------------------------------------------------------------------------------------------- [22:26:24] Ryan Stout(@ryanstout):yea, I think opal will play a big part in ruby's future :-) ---------------------------------------------------------------------------------------------------- [22:26:57] Loïc Boutet(@loicboutet):I think so too ---------------------------------------------------------------------------------------------------- [22:27:07] Loïc Boutet(@loicboutet):what was your motivation when starting volt? ---------------------------------------------------------------------------------------------------- [22:43:18] George(@georgeu2000):Why do you want to put the logic in the view? ---------------------------------------------------------------------------------------------------- [22:44:12] Loïc Boutet(@loicboutet):well I'm talking about if else / each function kind of logic ---------------------------------------------------------------------------------------------------- [22:44:45] George(@georgeu2000):I see. ---------------------------------------------------------------------------------------------------- [22:47:03] Ryan Stout(@ryanstout):@loicboutet I mostly build very front-end heavy apps, and I wasn't really happy with rails+angular (or ember) ---------------------------------------------------------------------------------------------------- [22:47:37] Ryan Stout(@ryanstout):@georgeu2000 yea, the idea isn't to put "logic" in there, but you can call methods and stuff from bindings ---------------------------------------------------------------------------------------------------- [22:48:06] Ryan Stout(@ryanstout):but it's not a logic-less templating language, though you could use it that way ---------------------------------------------------------------------------------------------------- [22:48:19] Loïc Boutet(@loicboutet):ok ! ---------------------------------------------------------------------------------------------------- [22:48:33] Loïc Boutet(@loicboutet):do you have things in production built with volt already? ---------------------------------------------------------------------------------------------------- [22:48:58] Ryan Stout(@ryanstout):@loicboutet nothing huge, just some small stuff ---------------------------------------------------------------------------------------------------- [22:49:07] Ryan Stout(@ryanstout):working on a larger one now ---------------------------------------------------------------------------------------------------- [22:49:13] Loïc Boutet(@loicboutet):ok ! ---------------------------------------------------------------------------------------------------- [22:50:05] Loïc Boutet(@loicboutet):hey, byt the way, something totally different ---------------------------------------------------------------------------------------------------- [22:50:10] Loïc Boutet(@loicboutet):but have you seen https://github.com/BrewhouseTeam/angular_sprinkles ? ---------------------------------------------------------------------------------------------------- [22:50:22] Loïc Boutet(@loicboutet):what do you think about it? ---------------------------------------------------------------------------------------------------- [22:50:47] Ryan Stout(@ryanstout):I haven't seen it ---------------------------------------------------------------------------------------------------- [22:50:54] Ryan Stout(@ryanstout):looks like its useful ---------------------------------------------------------------------------------------------------- [22:51:13] AstonJ(@AstonJ):I saw Sprinkles (think there’s a blog post about it as well) but it’s still Angular. I would prefer to use Opal/Volt ---------------------------------------------------------------------------------------------------- [22:53:02] AstonJ(@AstonJ):Going back to tempting - I think {{ }} will continue to have negative connotations. I reckon switching to <% is going to be a very positive move (of I will stop going on about it now lol) ---------------------------------------------------------------------------------------------------- [22:53:15] AstonJ(@AstonJ):of = ok ---------------------------------------------------------------------------------------------------- [22:54:12] Loïc Boutet(@loicboutet):well, I understand your point about <% in html... but I agree with Astonj, in term of user adoption I think <% is the way to go ---------------------------------------------------------------------------------------------------- [22:54:24] AstonJ(@AstonJ):Great conversation too - I reckon a blog post on the topic would be a neat idea. ---------------------------------------------------------------------------------------------------- [22:55:03] Loïc Boutet(@loicboutet):Ryan > do you think your ideas in volt could be ported to rails? ---------------------------------------------------------------------------------------------------- [22:55:31] Loïc Boutet(@loicboutet):a kind of volt-rails gem ? ---------------------------------------------------------------------------------------------------- [22:56:15] AstonJ(@AstonJ):Yeah @loicboutet I think it will help create less barriers. Plus we mustn’t forget so many of us dislike brackets-heavy languages, and {{}} seems to represent that (ok definitely shutting up now!) ---------------------------------------------------------------------------------------------------- [22:56:57] Loïc Boutet(@loicboutet):@AstonJ ahah yes ---------------------------------------------------------------------------------------------------- [22:57:59] AstonJ(@AstonJ):Interesting idea @loicboutet but I wonder if part of Volt’s appeal is that it’s a rack-app, built for the modern web - so might be less bloated and dare I say it, more scalable? (No idea if that’s actually the case) ---------------------------------------------------------------------------------------------------- [22:59:09] Loïc Boutet(@loicboutet):Well, I guess you can make the point that rails is bloated :) ---------------------------------------------------------------------------------------------------- [22:59:31] Ryan Stout(@ryanstout):@loicboutet Volt and rails kind of approach things differently, so I don't think it would make since to try to integrate it into rails ---------------------------------------------------------------------------------------------------- [22:59:31] Loïc Boutet(@loicboutet):but it is also the most used framework in ruby by a large margin ---------------------------------------------------------------------------------------------------- [22:59:45] Loïc Boutet(@loicboutet):@ryanstout OK ---------------------------------------------------------------------------------------------------- [23:00:10] Loïc Boutet(@loicboutet):I'm just trying to find a way to import new ideas in existing projects without rewriting everything :) ---------------------------------------------------------------------------------------------------- [23:00:26] Loïc Boutet(@loicboutet):I'm working on a project right now, and it begin to be really js heavy ---------------------------------------------------------------------------------------------------- [23:00:28] Ryan Stout(@ryanstout):yea, thats always tricky ---------------------------------------------------------------------------------------------------- [23:00:55] Loïc Boutet(@loicboutet):I would be glad if I had a way to make it nicer and keeping the rails part :) ---------------------------------------------------------------------------------------------------- [23:01:09] Loïc Boutet(@loicboutet):that s why I was thinking about a vienna integration ---------------------------------------------------------------------------------------------------- [23:01:11] AstonJ(@AstonJ):Maybe bloated wasn’t a good word to use - but Rails is getting on now, there may well be stuff there that is a little outdated. Having said that, I do love Rails. The only thing I currently dislike is that they haven’t or have no plans to adopt Opal. ---------------------------------------------------------------------------------------------------- [23:01:54] Loïc Boutet(@loicboutet):yeah, well the best thing to do for them to change their mind is to integrate well with them ;) ---------------------------------------------------------------------------------------------------- [23:02:50] AstonJ(@AstonJ):They have big apps on Rails, and switching to Opal might be a lot of work for them - but I feel ignoring it will mean something like Volt could well come in and steal their thunder. ---------------------------------------------------------------------------------------------------- [23:03:11] Loïc Boutet(@loicboutet):that is definitely something that could happen ---------------------------------------------------------------------------------------------------- [23:03:47] Loïc Boutet(@loicboutet):the framework which will be unifying the front and the back with the modern requirement for both will definitely have a good shot :) ---------------------------------------------------------------------------------------------------- [23:04:33] AstonJ(@AstonJ):I’m personally very excited about Volt - it _feels_ cutting edge, not just as good as Angular and the rest, but better, because it’s Ruby. I reckon we will see some awesome things with it :D ---------------------------------------------------------------------------------------------------- [23:05:18] Loïc Boutet(@loicboutet):Actually I will have to check it out more :) ---------------------------------------------------------------------------------------------------- [23:05:31] Loïc Boutet(@loicboutet):I was kind of falling in love with vienna those last weeks ---------------------------------------------------------------------------------------------------- [23:05:40] Loïc Boutet(@loicboutet):I like it s simplicity and its core principle ---------------------------------------------------------------------------------------------------- [23:05:56] Loïc Boutet(@loicboutet):Now I might have to reconsider lol ---------------------------------------------------------------------------------------------------- [23:06:00] AstonJ(@AstonJ):Vienna looks awesome too :+1: ---------------------------------------------------------------------------------------------------- [23:06:13] Loïc Boutet(@loicboutet):well vienna is less disruptive ---------------------------------------------------------------------------------------------------- [23:06:25] Loïc Boutet(@loicboutet):you an keep your existing habit for the back end ---------------------------------------------------------------------------------------------------- [23:06:34] Loïc Boutet(@loicboutet):and have a nice front end framework in ruby ---------------------------------------------------------------------------------------------------- [23:06:47] AstonJ(@AstonJ):Admittedly, I haven’t looked too much into Vienna right now - but should... ---------------------------------------------------------------------------------------------------- [23:07:02] Loïc Boutet(@loicboutet):I think all is lacking is a good integration with rails/sinatra ---------------------------------------------------------------------------------------------------- [23:07:25] Loïc Boutet(@loicboutet):like making it super easy to use inside those kind of project ---------------------------------------------------------------------------------------------------- [23:07:30] Loïc Boutet(@loicboutet):and it could have an audience ---------------------------------------------------------------------------------------------------- [23:08:04] Loïc Boutet(@loicboutet):What I like about vienna is that it just attach logic to your html elements ---------------------------------------------------------------------------------------------------- [23:08:24] AstonJ(@AstonJ):You should give that feedback to @adambeynon and @elia - though, they are probably already on it :D ---------------------------------------------------------------------------------------------------- [23:08:31] Loïc Boutet(@loicboutet):like you say "ok, now this table is my object and I will add attribute to it, and teach it its business logic" ---------------------------------------------------------------------------------------------------- [23:08:53] Loïc Boutet(@loicboutet):I like the simplicity in that ---------------------------------------------------------------------------------------------------- [23:09:03] Loïc Boutet(@loicboutet):and from what I see it s working quite well (for me at least) ---------------------------------------------------------------------------------------------------- [23:09:08] AstonJ(@AstonJ):I feel a new blog post coming on…. “Ruby is about to get cool again!" ---------------------------------------------------------------------------------------------------- [23:09:13] Loïc Boutet(@loicboutet):ah ah ---------------------------------------------------------------------------------------------------- [23:09:38] Loïc Boutet(@loicboutet):I did a presentation kind of like that at the paris ruby meet up :p ---------------------------------------------------------------------------------------------------- [23:09:47] Loïc Boutet(@loicboutet):"ruby is not only for your servers anymore" ---------------------------------------------------------------------------------------------------- [23:10:01] AstonJ(@AstonJ):have you got the slides up anywhere? :page_facing_up: ---------------------------------------------------------------------------------------------------- [23:10:04] AstonJ(@AstonJ)::p ---------------------------------------------------------------------------------------------------- [23:10:28] Loïc Boutet(@loicboutet):kind of, http://www.rubyparis.org/videos/ruby-not-only-for-servers-loic-boutet ---------------------------------------------------------------------------------------------------- [23:10:38] Loïc Boutet(@loicboutet):but the talk is in french ^^ ---------------------------------------------------------------------------------------------------- [23:10:54] Loïc Boutet(@loicboutet):the slides are in english thought ---------------------------------------------------------------------------------------------------- [23:11:21] AstonJ(@AstonJ):Cool - thanks! My French is very rusty lol good to know the slides are in English ---------------------------------------------------------------------------------------------------- [23:11:43] AstonJ(@AstonJ):Nice chatting with you! I need to reboot (little snitch update) catch you laters ---------------------------------------------------------------------------------------------------- [23:11:53] Loïc Boutet(@loicboutet):sure :) ---------------------------------------------------------------------------------------------------- [23:18:39] Loïc Boutet(@loicboutet):In my talk I'm just using opal (and vienna) to make a very simple tic tac toe ---------------------------------------------------------------------------------------------------- [23:18:52] Loïc Boutet(@loicboutet):and then use the same code ---------------------------------------------------------------------------------------------------- [23:19:00] Loïc Boutet(@loicboutet):to have the tictactoe run in the browser ---------------------------------------------------------------------------------------------------- [23:19:20] Loïc Boutet(@loicboutet):then embed it in atom-shell to make a desktop app ---------------------------------------------------------------------------------------------------- [23:19:31] Loïc Boutet(@loicboutet):and then send it to the phonegap cloud to make a mobile app ---------------------------------------------------------------------------------------------------- [23:19:56] Loïc Boutet(@loicboutet):and then you have a working app running everywhere with the same base code in ruby :) ---------------------------------------------------------------------------------------------------- [23:27:35] George(@georgeu2000):@loicboutet - Wow, that's awesome. ---------------------------------------------------------------------------------------------------- [23:28:24] Loïc Boutet(@loicboutet):thx, well opal is doing all the heavy lifting ---------------------------------------------------------------------------------------------------- [23:28:36] Loïc Boutet(@loicboutet):after that it's just using already existing js tools ---------------------------------------------------------------------------------------------------- [23:29:00] Loïc Boutet(@loicboutet):the code is there if you want to look at it https://github.com/loicboutet/opal-tictactoe ---------------------------------------------------------------------------------------------------- [23:29:07] George(@georgeu2000):Cool. Thanks. ---------------------------------------------------------------------------------------------------- [23:29:09] Loïc Boutet(@loicboutet):it needs some clean up ---------------------------------------------------------------------------------------------------- [23:29:27] Loïc Boutet(@loicboutet):(I started from the vienna todo app and all the readme and stuff have not changed lol) ---------------------------------------------------------------------------------------------------- [23:30:00] George(@georgeu2000):I think a major pain point is that a lot of work is required to take a web app and convert to iOS and Android. And it is difficult to share code between them. ---------------------------------------------------------------------------------------------------- [23:30:00] Loïc Boutet(@loicboutet):I used some existing tictactoe class for the game logic ---------------------------------------------------------------------------------------------------- [23:30:12] Loïc Boutet(@loicboutet):made from another member of the ruby paris meetup ---------------------------------------------------------------------------------------------------- [23:30:18] Loïc Boutet(@loicboutet):just to prove you can reuse code in opal ---------------------------------------------------------------------------------------------------- [23:30:32] Loïc Boutet(@loicboutet):yes definitely ---------------------------------------------------------------------------------------------------- [21:03:25] Loïc Boutet(@loicboutet):Has anyone made a vienna app inside a rails app? ---------------------------------------------------------------------------------------------------- [21:04:00] Loïc Boutet(@loicboutet):I'm thinking that rails is quite useful when dealing with normal, mainly static webpage ---------------------------------------------------------------------------------------------------- [21:04:17] Loïc Boutet(@loicboutet):but not so much when you want a javascript heavy page ---------------------------------------------------------------------------------------------------- [21:04:31] Loïc Boutet(@loicboutet):vienna could be useful for handling this case ---------------------------------------------------------------------------------------------------- [21:05:09] Loïc Boutet(@loicboutet):you would made a small vienna app for handling the necessary js ---------------------------------------------------------------------------------------------------- [21:05:45] Loïc Boutet(@loicboutet):anyone has used it in such a fashion? ---------------------------------------------------------------------------------------------------- [21:46:49] AstonJ(@AstonJ):Sounds like a good idea @loicboutet - though you may want to look at voltframework.com as well :) ---------------------------------------------------------------------------------------------------- [21:47:47] Loïc Boutet(@loicboutet):well I like volt ---------------------------------------------------------------------------------------------------- [21:48:08] Loïc Boutet(@loicboutet):but personally I cannot think of a lot of use case to use it ---------------------------------------------------------------------------------------------------- [22:07:17] Ryan Stout(@ryanstout):@loicboutet going to put in my $0.02 on Volt. Its a bit early, but you will be able to build anything in it. The live updating is only one small feature. You can also do bindings that don't live update (here's a video showing that: https://www.youtube.com/watch?v=c478sMlhx1o) ---------------------------------------------------------------------------------------------------- [22:08:14] Ryan Stout(@ryanstout):I think the big win with volt is sharing code between client and server. I'm working on a demo that should the sharing better ---------------------------------------------------------------------------------------------------- [22:08:14] Loïc Boutet(@loicboutet):hmm ok ---------------------------------------------------------------------------------------------------- [22:08:38] Loïc Boutet(@loicboutet):Sharing code would definitly be a big plus ---------------------------------------------------------------------------------------------------- [22:08:55] Loïc Boutet(@loicboutet):I admit I probably should look more into it ---------------------------------------------------------------------------------------------------- [22:08:55] Ryan Stout(@ryanstout):not needing to do REST api's to sync data between client and server is also nice, imho ---------------------------------------------------------------------------------------------------- [22:09:32] Loïc Boutet(@loicboutet):When I saw it I kind of thought it is a sort of meteorjs for ruby ---------------------------------------------------------------------------------------------------- [22:09:57] Ryan Stout(@ryanstout):it is similar, but I think meteor failed to make it easy to build the usual CRUD apps. Volt's buffers make CRUD stuff really easy. ---------------------------------------------------------------------------------------------------- [22:10:06] Ryan Stout(@ryanstout):(again, imho) ---------------------------------------------------------------------------------------------------- [22:10:10] Loïc Boutet(@loicboutet):OK ---------------------------------------------------------------------------------------------------- [22:10:15] Loïc Boutet(@loicboutet):I agree with you with meteor ---------------------------------------------------------------------------------------------------- [22:10:24] Loïc Boutet(@loicboutet):and kind of thought that volt would have the same problem ---------------------------------------------------------------------------------------------------- [22:10:35] Ryan Stout(@ryanstout):I'm with you, realtime apps aren't that common ---------------------------------------------------------------------------------------------------- [22:10:43] Loïc Boutet(@loicboutet):since I understood the use case it was trying to solve was the live application stuff ---------------------------------------------------------------------------------------------------- [22:11:14] Loïc Boutet(@loicboutet):ok, we agree, and that mean I really have to dig deeper in volt ---------------------------------------------------------------------------------------------------- [22:11:41] Ryan Stout(@ryanstout):hit me up if you have any questions :-) hopefully I can get some more demo videos out soon ---------------------------------------------------------------------------------------------------- [22:12:01] Loïc Boutet(@loicboutet):can I ask you why the views use a custom templating language? ---------------------------------------------------------------------------------------------------- [22:12:27] Loïc Boutet(@loicboutet):is it necessary for the automatic dom update? ---------------------------------------------------------------------------------------------------- [22:13:19] Ryan Stout(@ryanstout):yea, the views got changed recently (the video's not updated). Now the views are basically just ruby in {{ and }} ---------------------------------------------------------------------------------------------------- [22:13:38] Loïc Boutet(@loicboutet):oh nice ! ---------------------------------------------------------------------------------------------------- [22:14:01] Loïc Boutet(@loicboutet):I was a bit put off by the templating to be honnest, never been a big fan of handlebars ---------------------------------------------------------------------------------------------------- [22:14:20] Ryan Stout(@ryanstout):I'm still considering switching to erb style. I personally like {{ and }} over <% and %>, but most rubyists seem to like erb style (because it's familiar I think) ---------------------------------------------------------------------------------------------------- [22:15:04] Loïc Boutet(@loicboutet):in my experience yes it is way more familiar, and I have been extremely frustrated when using mustache/handlebar ---------------------------------------------------------------------------------------------------- [22:15:26] Ryan Stout(@ryanstout):is part of the issue the {{ and }} ? ---------------------------------------------------------------------------------------------------- [22:15:41] Ryan Stout(@ryanstout):I always just thought doing <% in a html attribute seems weird (since your already in a tag) ---------------------------------------------------------------------------------------------------- [22:15:53] Loïc Boutet(@loicboutet):personnally it s not the {{ }} in themselve ---------------------------------------------------------------------------------------------------- [22:16:02] Loïc Boutet(@loicboutet):but the fact that I associate them with handlebar ---------------------------------------------------------------------------------------------------- [22:16:15] Loïc Boutet(@loicboutet):and handlebar is good when you juste want to put value in the template ---------------------------------------------------------------------------------------------------- [22:16:26] Loïc Boutet(@loicboutet):but sucks (imho) for logic stuff ---------------------------------------------------------------------------------------------------- [22:16:59] Ryan Stout(@ryanstout):yea, I agree on that ---------------------------------------------------------------------------------------------------- [22:17:06] Ryan Stout(@ryanstout):doing #each /each is weird too ---------------------------------------------------------------------------------------------------- [22:17:08] Loïc Boutet(@loicboutet):so when I had to use it I was kind of frustrated, so now I'm wincing at the sight lol ---------------------------------------------------------------------------------------------------- [22:17:12] Loïc Boutet(@loicboutet):yeah ---------------------------------------------------------------------------------------------------- ############################## [2014-10-08] ############################## [22:03:00] George(@georgeu2000):@elia - Do you know why `puts` statements converted to JS and run in tests with poltergeist print to the console? ---------------------------------------------------------------------------------------------------- [22:03:13] George(@georgeu2000):Is this coming from Poltergeist or Opal? ---------------------------------------------------------------------------------------------------- [22:03:45] George(@georgeu2000):Is there a way I can distinguish between code running in Poltergeist and running in a browser? ---------------------------------------------------------------------------------------------------- [22:04:07] George(@georgeu2000):I checked RUBY_ENGINE.

Know where I can read more about Fire? ---------------------------------------------------------------------------------------------------- [18:59:32] AstonJ(@AstonJ):Hi @andrewhavens, the link is meant to go to the same post http://astonj.com/tech/ruby-is-about-to-get-red-hot-again/ but @adambeynon hasn’t updated the page yet. If you have any questions or suggestions about Fire feel free to post them here :) ---------------------------------------------------------------------------------------------------- [18:59:57] Andrew Havens(@andrewhavens):Okay...what is Fire? =] ---------------------------------------------------------------------------------------------------- [19:01:28] AstonJ(@AstonJ):A fourthcoming frontend Ruby framework. Vienna is more of a backbone styly library but Fire is intended to be a full framework. ---------------------------------------------------------------------------------------------------- [19:01:47] Andrew Havens(@andrewhavens):So more like Ember? ---------------------------------------------------------------------------------------------------- [19:02:11] AstonJ(@AstonJ):Yeah - Ruby’s answer to Angular and Ember :) ---------------------------------------------------------------------------------------------------- [19:02:17] Andrew Havens(@andrewhavens):Ah okay ---------------------------------------------------------------------------------------------------- [19:02:25] Andrew Havens(@andrewhavens):that's a good way to put it ---------------------------------------------------------------------------------------------------- [19:03:11] Andrew Havens(@andrewhavens):Is it intended to be more like Volt/Meteor? Or more like Angular/Ember? ---------------------------------------------------------------------------------------------------- [19:03:29] AstonJ(@AstonJ):Good point - I’ll see if I can add that to the post later. ---------------------------------------------------------------------------------------------------- [19:04:13] AstonJ(@AstonJ):More like A/E but I think @adambeynon has plans to incorporate some reactive stuff (from Volt) too ---------------------------------------------------------------------------------------------------- [19:06:50] AstonJ(@AstonJ):What would you like to see in Fire? When we spoke about it initially the general consensus was to be Ruby’s answer to Angular and Ember, but going a step beyond what they do too. ---------------------------------------------------------------------------------------------------- [19:09:59] Andrew Havens(@andrewhavens):Well, I would think "Ruby's answer to Angular/Ember" would mean simpler syntax, more integrated with Ruby frameworks. Not sure if there is truly a "Ruby way" that a front-end framework should be... ---------------------------------------------------------------------------------------------------- [19:10:34] Andrew Havens(@andrewhavens):For example, I personally prefer Backbone over Angular and Ember. But many people prefer the latter for certain reasons ---------------------------------------------------------------------------------------------------- [19:13:01] Andrew Havens(@andrewhavens):I like the simplicity of Backbone. It's easy to learn and sprinkle into your project without assuming you're building a single-page app. I like the Rails-like conventions with Ember, and I strongly dislike the Angular approach to custom HTML attributes and mixing javascript in the HTML. There's also a lot to learn with Ember/Angular. ---------------------------------------------------------------------------------------------------- [19:16:34] Andrew Havens(@andrewhavens):I'm not sure what you have already discussed in terms of things that would make it "a step beyond A/E" but I'm guessing that making a strong statement about the types of problems Fire is intended to solve will help clarify the features of the framework. I don't think it is wise to assume it will be **the** Ruby front-end framework. Kind of like Rails/Sinatra...there is a place for both. It's best to clarify the problems you are trying to solve. ---------------------------------------------------------------------------------------------------- [19:45:29] ylluminate(@ylluminate):well written article @AstonJ! :) ---------------------------------------------------------------------------------------------------- [20:20:10] verdi327(@verdi327):Read the article, great stuff. ---------------------------------------------------------------------------------------------------- [20:20:22] verdi327(@verdi327):Excited about Ruby's future ---------------------------------------------------------------------------------------------------- [20:22:09] Andrew Havens(@andrewhavens):trying to read through the opal-jquery source, and am confused about this line: https://github.com/opal/opal-jquery/blob/master/opal/opal-jquery/element.rb#L1 (where can I find the source of “native”?) ---------------------------------------------------------------------------------------------------- [20:28:06] Adam Beynon(@adambeynon):hi @andrewhavens ---------------------------------------------------------------------------------------------------- [20:28:07] Adam Beynon(@adambeynon):https://github.com/opal/opal/blob/master/stdlib/native.rb ---------------------------------------------------------------------------------------------------- [20:28:23] Adam Beynon(@adambeynon):that is the Native module, it makes it nicer to deal with wrapped js objects ---------------------------------------------------------------------------------------------------- [20:30:00] Adam Beynon(@adambeynon):we use it inside Element for wrapping #offset() from jquery ---------------------------------------------------------------------------------------------------- [20:30:02] Andrew Havens(@andrewhavens):ah ok, couldnt find it because i was looking in corelib ---------------------------------------------------------------------------------------------------- [20:30:42] Adam Beynon(@adambeynon):opal-browser (an alternative, jquery-less, dom library) uses it a lot to great avail ---------------------------------------------------------------------------------------------------- [20:31:36] Andrew Havens(@andrewhavens):Next question…what does this mean? `$$[:jQuery]` https://github.com/opal/opal-jquery/blob/master/opal/opal-jquery/constants.rb#L5 ---------------------------------------------------------------------------------------------------- [20:34:29] Adam Beynon(@adambeynon):`$$` is a global defined inside `native.rb`. It is a wrapped `window` object, aka the `global` object ---------------------------------------------------------------------------------------------------- [20:34:43] Adam Beynon(@adambeynon):so we are essentially checking if `jQuery` is defined on `window` ---------------------------------------------------------------------------------------------------- [20:35:06] Adam Beynon(@adambeynon):if not, then we check for zepto, otherwise raise an error ---------------------------------------------------------------------------------------------------- [20:35:33] Andrew Havens(@andrewhavens):Oh I see https://github.com/opal/opal/blob/master/stdlib/native.rb#L532 ---------------------------------------------------------------------------------------------------- [20:36:12] Adam Beynon(@adambeynon):there was some debate about using `$$`, but Im getting to like it more and more ---------------------------------------------------------------------------------------------------- [20:36:16] Adam Beynon(@adambeynon):works with method calls as well ---------------------------------------------------------------------------------------------------- [20:36:27] Adam Beynon(@adambeynon):`$$.alert “foo”` => `window.alert(“foo”)` ---------------------------------------------------------------------------------------------------- [20:37:15] Andrew Havens(@andrewhavens):that’s interesting ---------------------------------------------------------------------------------------------------- [20:39:36] Adam Beynon(@adambeynon):of course, docs are something that are missing in opal :( ---------------------------------------------------------------------------------------------------- [20:39:38] Andrew Havens(@andrewhavens):So what is the difference between `$$.jQuery` and `$$[:jQuery]`? ---------------------------------------------------------------------------------------------------- [20:40:27] Adam Beynon(@adambeynon):yes, the first form will actually call the `jQuery` function, where as the second form will just return it (or nil if it doesnt exist) ---------------------------------------------------------------------------------------------------- [20:44:00] Andrew Havens(@andrewhavens):Okay, seems like the magic is in Native(\`Opal.global\`)…where is the source of that? ---------------------------------------------------------------------------------------------------- [20:44:48] Adam Beynon(@adambeynon):https://github.com/opal/opal/blob/master/opal/corelib/runtime.js#L26 ---------------------------------------------------------------------------------------------------- [20:45:03] Adam Beynon(@adambeynon):`runtime.js` is where most of the magic happens ---------------------------------------------------------------------------------------------------- [20:46:50] Andrew Havens(@andrewhavens):oh weird! ---------------------------------------------------------------------------------------------------- [20:49:28] Andrew Havens(@andrewhavens):What is `this` in this context? It looks like it gets set to `window` https://github.com/opal/opal/blob/master/opal/corelib/runtime.js#L1239 ---------------------------------------------------------------------------------------------------- [20:51:41] Andrew Havens(@andrewhavens):I expexted `Opal.global` to be some object which handled the translation of ruby method/accessor syntax into javascript. But it’s just `window` so now it really seems like magic ---------------------------------------------------------------------------------------------------- [20:59:10] Brandon Zylstra(@brandondrew):@adambeynon : the problem of missing docs is the reason (IMHO) we don't see more people jumping into Opal. I discovered it several months ago and was very excited, but gave up when it seemed like there were just a few important pieces either missing or undocumented. ---------------------------------------------------------------------------------------------------- [21:15:21] Jamon Holmgren(@jamonholmgren):Excellent documentation is one of the most critical parts to systems like this, IMHO. It's one of the reasons our RubyMotion framework ProMotion has gained traction...people like the docs. ---------------------------------------------------------------------------------------------------- [21:43:43] AstonJ(@AstonJ):Sorry @andrewhavens I didn’t mean to run off like that but I was at the pool/sauna. ---------------------------------------------------------------------------------------------------- [21:43:47] AstonJ(@AstonJ):Thanks @ylluminate ! ---------------------------------------------------------------------------------------------------- [21:44:25] AstonJ(@AstonJ):I agree @brandondrew and @jamonholmgren - I hope to help out with Fire docs as much as I can ---------------------------------------------------------------------------------------------------- [22:47:35] Andrew Havens(@andrewhavens):@AstonJ No worries ---------------------------------------------------------------------------------------------------- [22:54:43] AstonJ(@AstonJ):I think it would be a good idea to set a forum up soon, particularly for Fire, Volt and Opal discussions. Perhaps at metaruby.com (in a subdomain) ---------------------------------------------------------------------------------------------------- [23:00:33] Andrew Havens(@andrewhavens):haven’t heard of metaruby.com…who runs that? What’s it for? ---------------------------------------------------------------------------------------------------- [23:56:08] AstonJ(@AstonJ):@andrewhavens I planned on putting a Ruby forum there a while back but never got around to it. I’m now thinking about putting a forum in a subdomain, and putting screencasts on the main site - not sure yet tbh. I’d like it to be somewhere anyone can upload screencasts ideally - a place to learn and share what you know. ---------------------------------------------------------------------------------------------------- ############################## [2014-10-31] ############################## [00:03:35] Andrew Havens(@andrewhavens):It’s a little bit of a ghost town right now =] ---------------------------------------------------------------------------------------------------- [00:03:49] Andrew Havens(@andrewhavens):Also it’s missing a ton of basic features ---------------------------------------------------------------------------------------------------- [00:04:06] AstonJ(@AstonJ)://Off-topic//That’s a wicked idea - definitely a topic that we don’t hear enough of :) ---------------------------------------------------------------------------------------------------- [00:05:10] AstonJ(@AstonJ):If you’re going to be a forum (discussion platform) I recommend using one of the leading apps - my two current faves are Discourse, and Xenforo - they really do help foster a community and facilitate discussion ---------------------------------------------------------------------------------------------------- [00:05:23] AstonJ(@AstonJ):My latest forum is www.forum.breedia.com (xenforo) ---------------------------------------------------------------------------------------------------- [00:07:04] AstonJ(@AstonJ):I also coded a forum/twitter app for an old gaming forum (in about two weeks) but haven’t had time to go any further with it (to the point where I feel we should just move back to a more fully featured forum app) www.gameslurp.com ---------------------------------------------------------------------------------------------------- [00:07:48] Andrew Havens(@andrewhavens):I definitely looked into Discourse and Forem, but they weren’t right for where I’m planning to go with it…would have needed to customize too much ---------------------------------------------------------------------------------------------------- [00:08:23] AstonJ(@AstonJ):How is your forum different to conventional forums (like DC)? ---------------------------------------------------------------------------------------------------- [00:09:38] AstonJ(@AstonJ):A forum built in Volt or Fire would be pretty neat :D ---------------------------------------------------------------------------------------------------- [00:09:47] Andrew Havens(@andrewhavens):It’s not really meant to be a “forum”…more like a combination of a wiki, reddit, stackoverflow, and ruby toolbox ---------------------------------------------------------------------------------------------------- [00:11:06] Andrew Havens(@andrewhavens):The idea is to centralize all of these different things into a central location based on a specific topic (ruby game programming) ---------------------------------------------------------------------------------------------------- [00:11:52] Andrew Havens(@andrewhavens):I recently redesigned the homepage so that it appears as a single list (looks more like a forum that way I guess) but it used to be much more separate ---------------------------------------------------------------------------------------------------- [00:12:09] AstonJ(@AstonJ):Ah right, cool.

(Topics/replies)? ---------------------------------------------------------------------------------------------------- [00:14:18] Andrew Havens(@andrewhavens):Right now, it looks like a forum, but that’s not the end-goal ---------------------------------------------------------------------------------------------------- [00:15:23] Andrew Havens(@andrewhavens):Anyway, need to head home now, we should continue this discussion in the RubyGameDev.com Gitter room: https://gitter.im/ruby-rcade/RubyGameDev.com ---------------------------------------------------------------------------------------------------- [00:15:26] Andrew Havens(@andrewhavens):=] ---------------------------------------------------------------------------------------------------- [00:15:37] AstonJ(@AstonJ):Cool ---------------------------------------------------------------------------------------------------- [00:17:57] Dan McGuire(@dgmcguire):I'm an intermediate ruby dev, how hard would it be to port my basic emberJS blog over too vienna? Would you suggest I go ahead and try fire? ---------------------------------------------------------------------------------------------------- [00:18:45] Dan McGuire(@dgmcguire):All I'm doing is authentication and basic crud, I used a few JS plugins, but they aren't that important to me ---------------------------------------------------------------------------------------------------- [00:21:45] AstonJ(@AstonJ):Hi @dgmcguire, Adam ( @adambeynon can provide you with a better answer) but he’s currently working on a very early alpha of Fire - I’d say wait for that and see how you feel - your three options are Vienna, Fire and Volt ---------------------------------------------------------------------------------------------------- [00:31:15] Dan McGuire(@dgmcguire):@AstonJ cool, I'm messing with vienna now, any place to find a tutorial yet? ---------------------------------------------------------------------------------------------------- [00:55:58] AstonJ(@AstonJ):Unfortunately not yet.

I am seeing Opal finally as a way to skip learning that, is that a bad decision? Should I go and learn some JS or else will I end up messing too much? ---------------------------------------------------------------------------------------------------- [14:47:11] Elia Schito(@elia):@JikkuJose problem is even with opal you need to learn DOM if you work in the browser ---------------------------------------------------------------------------------------------------- [14:48:57] Elia Schito(@elia):also it’s still good to know a bit of JS for debugging, the more you’ll learn JS the more you’ll appreciate opal ---------------------------------------------------------------------------------------------------- [14:49:43] Elia Schito(@elia):@JikkuJose but I’d like to hear how it goes if you start doing opal without prior js knowledge ---------------------------------------------------------------------------------------------------- [14:56:57] AstonJ(@AstonJ):I actually think this is a great oppourtunity for Opal - to allow people to bypass JS. I think it would nurture a new mindset in browser development as people won’t feel they need to ‘think’ in JS. So yeah, agree with @elia it’s probably best to learn about the DOM, CSS, HTML and just enough about JS so you have a good enough idea about it.. ---------------------------------------------------------------------------------------------------- [14:58:05] Elia Schito(@elia):@AstonJ also if tooling gets better that could really become viable, by this I mean source-maps and the like ---------------------------------------------------------------------------------------------------- [19:32:20] Jon Frisby(@MrJoy):Can anyone let me know what the state-of-the-world is for VoltRB's `precompile` command? ---------------------------------------------------------------------------------------------------- [19:35:06] Jon Frisby(@MrJoy):I just submitted a PR to fix a few issues with it, but it doesn't appear to be using Sprockets, etc yet. Wondering if that's planned, partially-implemented-but-not-working, or if environments are a factor. ---------------------------------------------------------------------------------------------------- [19:35:54] Andrew Havens(@andrewhavens):@MrJoy Perhaps you intended this message to be posted in the Volt room? ---------------------------------------------------------------------------------------------------- [19:36:13] Jon Frisby(@MrJoy):The Volt repo links here, so I thought the discussions were unified? ---------------------------------------------------------------------------------------------------- [19:36:28] Andrew Havens(@andrewhavens):Oh interesting ---------------------------------------------------------------------------------------------------- [19:36:55] Jon Frisby(@MrJoy):Errr... ---------------------------------------------------------------------------------------------------- [19:37:00] Jon Frisby(@MrJoy):Ok, something VoltRB linked here. >.< ---------------------------------------------------------------------------------------------------- [19:37:08] Jon Frisby(@MrJoy):The README on the repo links to the proper room. ---------------------------------------------------------------------------------------------------- [19:37:13] Andrew Havens(@andrewhavens):oh haha, okay ---------------------------------------------------------------------------------------------------- [19:38:03] Jon Frisby(@MrJoy):I'll dig up where I got the link from and prod them to update it. ---------------------------------------------------------------------------------------------------- [19:40:59] Jon Frisby(@MrJoy):Ohhh.

---------------------------------------------------------------------------------------------------- [21:31:18] Ryan Stout(@ryanstout):ok, one other thing (that I think was an issue in 0.6) ---------------------------------------------------------------------------------------------------- [21:32:38] Ryan Stout(@ryanstout):if I do this: ``` if RUBY_PLATFORM == 'opal' else ... some code ... end ``` it works, but if I do this: ``` if RUBY_PLATFORM != 'opal' ... some code ... end ``` I get ```Error: SyntaxError: Cannot handle dynamic require :volt/config``` ---------------------------------------------------------------------------------------------------- [21:32:45] Ryan Stout(@ryanstout):so it sounds like the pre-processor doesn't pickup on the != ---------------------------------------------------------------------------------------------------- [21:33:20] Elia Schito(@elia):that’s correct, only `==` with if/unless/else ---------------------------------------------------------------------------------------------------- [21:38:00] Ryan Stout(@ryanstout):any chance you can add != ---------------------------------------------------------------------------------------------------- [21:38:20] Ryan Stout(@ryanstout):oh, sorry, didn't realize unless worked ---------------------------------------------------------------------------------------------------- [21:38:23] Elia Schito(@elia):not atm, but should be quite easy ---------------------------------------------------------------------------------------------------- [21:38:23] Ryan Stout(@ryanstout):I thought it was just if ---------------------------------------------------------------------------------------------------- [21:38:35] Elia Schito(@elia)::) ---------------------------------------------------------------------------------------------------- [21:44:26] Adam Beynon(@adambeynon):I do occasionally type != as well. Should add it really ---------------------------------------------------------------------------------------------------- [21:44:36] Ryan Stout(@ryanstout):sometimes I think != is clearer ---------------------------------------------------------------------------------------------------- [21:45:00] Ryan Stout(@ryanstout):unless only reads like english in some cases (imho) ---------------------------------------------------------------------------------------------------- [21:45:14] Ryan Stout(@ryanstout):@adambeynon btw, great work on 0.7 :-) ---------------------------------------------------------------------------------------------------- [21:46:42] Adam Beynon(@adambeynon)::D ---------------------------------------------------------------------------------------------------- [21:46:50] Adam Beynon(@adambeynon):reading the above now ---------------------------------------------------------------------------------------------------- [21:46:57] Adam Beynon(@adambeynon):hows the -> 0.7 transition going ---------------------------------------------------------------------------------------------------- [21:47:19] Adam Beynon(@adambeynon):regarding opal-rspec, I think you will need to run it straight from git as well ---------------------------------------------------------------------------------------------------- [21:48:34] Ryan Stout(@ryanstout):@adambeynon I was running the beta gem, but are there updates on git? ---------------------------------------------------------------------------------------------------- [21:49:25] Adam Beynon(@adambeynon):@ryanstout yeap. There are fixes from stuff that was fixed in opal ---------------------------------------------------------------------------------------------------- [21:49:34] Ryan Stout(@ryanstout):ok, let me try that ---------------------------------------------------------------------------------------------------- [21:49:45] Adam Beynon(@adambeynon):really need to release another beta gem, but git/master is pretty sturdy ---------------------------------------------------------------------------------------------------- [21:49:52] Adam Beynon(@adambeynon):also, awesome news on rubyconf (Y) ---------------------------------------------------------------------------------------------------- [21:49:59] Ryan Stout(@ryanstout):thanks, I'll talk up opal :-) ---------------------------------------------------------------------------------------------------- [21:51:01] Ryan Stout(@ryanstout):dumb question, I'm using opal-rspec to test volt, if I put the git repo in the Gemfile, do I need to remove it from the gemspec? ---------------------------------------------------------------------------------------------------- [21:51:53] Adam Beynon(@adambeynon):dont think so. I always assumed a gemfile entry would override a gemspec ---------------------------------------------------------------------------------------------------- [21:52:01] Adam Beynon(@adambeynon):that might be completely false though ^_- ---------------------------------------------------------------------------------------------------- [21:52:34] Ryan Stout(@ryanstout):I'll try it :-) ---------------------------------------------------------------------------------------------------- [21:52:50] Adam Beynon(@adambeynon):@ryanstout the github repo is on the same version as the latest gem though, so it shouldnt cause versioning issues ---------------------------------------------------------------------------------------------------- [21:52:58] Ryan Stout(@ryanstout):ok ---------------------------------------------------------------------------------------------------- [22:00:29] Ryan Stout(@ryanstout):@adambeynon or @elia so I've got a weird issue running specs, I was hoping maybe you guys might have an idea.

We would probably need a very thin wrapper around it to handle ruby hashes => js objects for configuring the elements, but it should work fine ---------------------------------------------------------------------------------------------------- [15:27:54] Adam Beynon(@adambeynon):I did play around with an opal + reactjs bridge, which I guess is the same direction ---------------------------------------------------------------------------------------------------- [15:28:30] Adam Beynon(@adambeynon):@bglusman the reactjs bridge was actually a HAML => jsx compiler ---------------------------------------------------------------------------------------------------- [15:28:42] Adam Beynon(@adambeynon):to avoid ruby hashes => js object conversion ---------------------------------------------------------------------------------------------------- [15:31:56] Elia Schito(@elia):@adambeynon you _have to_ to share it :) ---------------------------------------------------------------------------------------------------- [15:41:00] Adam Beynon(@adambeynon):@elia sure! it needs a lot of work, so contributions would be welcome! ;) ---------------------------------------------------------------------------------------------------- [15:41:36] Elia Schito(@elia):@adambeynon just gimme a repo :shipit: ---------------------------------------------------------------------------------------------------- [20:04:51] Brian Glusman(@bglusman):@adambeynon thanks, just curious if a useful direction to think to make volt/opal higher performance etc, not sure where/how it makes sense to consider… I don’t think react makes sense for volt, but other virtual dom wrapper might. I also just had idea this mornign to try to make volt components into general web components that can be integrated freely into rails and sinatra apps which would be awesome, but dunno how big a lift it would be :-) ---------------------------------------------------------------------------------------------------- [21:27:37] Jared White(@jaredcwhite):Just heard about RubyFire - very interested! I worked on some code a while back that provided some simple front-end controller pieces and a view-model layer that was a wrapper around KnockoutJS, but ended up putting it all on hold because I don't want to be dependent on Knockout. My overall goal was to provide a nice modular client-side framework to compliment Rails well. But I think I'll be happy now to wait to check out Fire's repo and maybe contribute any ideas if applicable at that point. :) ---------------------------------------------------------------------------------------------------- ############################## [2014-11-12] ############################## [21:24:32] Ryan Stout(@ryanstout):Is anyone around who can help me with sourcemaps?

Most likely the connection points between your custom app code and the grid component will be fairly contained (or should be!), in which case you simply write an adapter to cross the divide between the JS and the Ruby code. I haven't made much use of the Native wrapper stuff but that might get you a fair ways along. ---------------------------------------------------------------------------------------------------- [17:03:48] Brandon Zylstra(@brandondrew):Would it be insanely ridiculous to try to make write an opal app that includes an Angular component, like the UI-Grid? ---------------------------------------------------------------------------------------------------- [17:03:51] Brandon Zylstra(@brandondrew):http://ui-grid.info/docs/#/tutorial/401_AllFeatures ---------------------------------------------------------------------------------------------------- ############################## [2014-12-06] ############################## [17:22:13] Can Edremitoglu(@cantonic):hi everybody. i am using the stable version of opal-rails from rubygems (0.6.3) because I want to run it in production. would you recommend to use the 0.7 even if it is in beta? ---------------------------------------------------------------------------------------------------- [17:26:43] Can Edremitoglu(@cantonic):since i am totally new to opal i have no clue how stable the beta or even the master branch on github is ---------------------------------------------------------------------------------------------------- ############################## [2014-12-07] ############################## [22:48:33] Ryan Stout(@ryanstout):@adambeynon nice work on keyword args :-) ---------------------------------------------------------------------------------------------------- [23:09:10] Adam Beynon(@adambeynon)::metal: ---------------------------------------------------------------------------------------------------- ############################## [2014-12-08] ############################## [04:04:02] Ryan Stout(@ryanstout):@adambeynon @elia does subclassing Hash work in opal? ---------------------------------------------------------------------------------------------------- [04:04:10] Ryan Stout(@ryanstout):I know it didn't work at one point ---------------------------------------------------------------------------------------------------- [08:15:06] Adam Beynon(@adambeynon):@ryanstout yep, subclassing hash works just fine now ---------------------------------------------------------------------------------------------------- ############################## [2014-12-13] ############################## [14:36:23] Brandon Zylstra(@brandondrew):@jaredcwhite : thanks!

Was the decision made that `.Kernel` had to be explicit, to avoid too many global methods getting tacked onto Opal, or to avoid a collision, perhaps? ---------------------------------------------------------------------------------------------------- [21:06:05] Brandon Zylstra(@brandondrew):Any news on Fire? ---------------------------------------------------------------------------------------------------- ############################## [2014-12-27] ############################## [03:11:41] ylluminate(@ylluminate):hope everyone had happy holidays so far and have a great new year! ---------------------------------------------------------------------------------------------------- [03:12:36] Can Edremitoglu(@cantonic):wish you the same! ---------------------------------------------------------------------------------------------------- [04:48:32] ylluminate(@ylluminate):thanks! ---------------------------------------------------------------------------------------------------- [13:01:01] Elia Schito(@elia):@brandondrew (catching up with chats after Christmas…) ---------------------------------------------------------------------------------------------------- [13:01:59] Elia Schito(@elia):you're right, not sure when the change happened, an alternative to using the Kernel module directly is to use the top level object, like this: `Opal.top.$puts("hi!")` ---------------------------------------------------------------------------------------------------- [20:24:51] Sean Culver(@seanculver):is there support for Matrix objects in opal? ---------------------------------------------------------------------------------------------------- [20:26:37] Sean Culver(@seanculver):http://www.ruby-doc.org/stdlib-2.0/libdoc/matrix/rdoc/Matrix.html ---------------------------------------------------------------------------------------------------- [23:25:46] Elia Schito(@elia):@seanculver nope, but I'd be glad to accept a PR for it, the list of stuff already in the stdlib is this: https://github.com/opal/opal/tree/master/stdlib ---------------------------------------------------------------------------------------------------- [23:37:12] Brandon Zylstra(@brandondrew):@adambeynon @elia are you the people to direct questions to about Fire? ---------------------------------------------------------------------------------------------------- [23:37:31] Elia Schito(@elia):@brandondrew, just @adambeynon ---------------------------------------------------------------------------------------------------- [23:38:04] Elia Schito(@elia):it's basically a rewrite of Vienna, so in the meantime I guess you can have a look at it ---------------------------------------------------------------------------------------------------- [23:38:44] Brandon Zylstra(@brandondrew):you mean the features and API will mirror those of Vienna? ---------------------------------------------------------------------------------------------------- [23:39:16] Brandon Zylstra(@brandondrew):or is it a completely new approach? ---------------------------------------------------------------------------------------------------- ############################## [2014-12-28] ############################## [00:13:43] Elia Schito(@elia):@brandondrew, not sure actually, that's why @adambeynon is your man, anyway iirc it stems from a modified version of it he had in one of his applications ---------------------------------------------------------------------------------------------------- [00:15:15] Elia Schito(@elia):@brandondrew, with a much more integrated support for rails out of the box, like for models, routes etc ---------------------------------------------------------------------------------------------------- [01:34:21] Sean Culver(@seanculver):@elia I'm willing to look into it, Javascript doesn't natively have a Matrix object. Can we use third party libraries to support stdlib, http://mathjs.org/docs/datatypes/matrices.html seems like a partial fit. Any docs that you can point me towards writing stdlib classes? ---------------------------------------------------------------------------------------------------- [11:24:59] Elia Schito(@elia):@seanculver best approach I think is to look at other files already in stdlib, as for the external lib I think it would be generally ok, but would be preferable to keep size and feature set of the imported lib as small as possible ---------------------------------------------------------------------------------------------------- ############################## [2014-12-30] ############################## [23:05:37] Ryan Stout(@ryanstout):I'm sure someone has asked this before, but is there a way I can call a JS func from opal and pass a block as a function? ---------------------------------------------------------------------------------------------------- [23:54:18] Luke Barbuto(@lexun):Are you talking about passing a ruby block as an argument to a javascript function that should treat the block like a function? something like this? ``` b = proc { return 'hi' } ` f = function(block) { console.log(block()) }; f(b) ` ``` ---------------------------------------------------------------------------------------------------- [23:57:31] Luke Barbuto(@lexun):because as far as I can see blocks just get compiled to functions ---------------------------------------------------------------------------------------------------- ############################## [2014-12-31] ############################## [00:13:50] Ryan Stout(@ryanstout):@lexun thats what I thought, but it wasn't working for me for some reason.

The best practive is to `require ‘opal’` somewhere inside your .rb file ---------------------------------------------------------------------------------------------------- [23:39:41] George(@georgeu2000):So, does that load ~800KB of javascript into the browser? ---------------------------------------------------------------------------------------------------- [23:40:31] Adam Beynon(@adambeynon):Last time I used opal.js directly it was about 200-300kb un-minified ---------------------------------------------------------------------------------------------------- [23:40:48] Adam Beynon(@adambeynon):800kb sounds like you have the compiler included in that as well ---------------------------------------------------------------------------------------------------- [23:40:53] Adam Beynon(@adambeynon):where is this opal.js file from? ---------------------------------------------------------------------------------------------------- [23:41:37] George(@georgeu2000):I think I compiled it myself...worked on it a few months ago so I forgot... ---------------------------------------------------------------------------------------------------- [23:42:06] Adam Beynon(@adambeynon):Ah ok. ---------------------------------------------------------------------------------------------------- [23:42:10] Adam Beynon(@adambeynon):We do supply pre compiled files ---------------------------------------------------------------------------------------------------- [23:42:11] Adam Beynon(@adambeynon):http://cdn.opalrb.org/ ---------------------------------------------------------------------------------------------------- [23:42:37] Adam Beynon(@adambeynon):but, I still recommend just requiring the runtime into your app/code to make sure its up to date with the compiler version ---------------------------------------------------------------------------------------------------- [23:43:33] George(@georgeu2000):So 200-300kb is the size of the Opal code that is sent to the browser? ---------------------------------------------------------------------------------------------------- [23:45:18] Elia Schito(@elia):georgeu2000, yes, unless you use the minified or minified+gz version which will be under 40k ---------------------------------------------------------------------------------------------------- [23:46:23] George(@georgeu2000):OK, got it. Thanks. I thought 800kb meant I was doing something wrong. ---------------------------------------------------------------------------------------------------- [23:46:38] George(@georgeu2000):@adambeynon - Thanks for the help! ---------------------------------------------------------------------------------------------------- [23:50:38] Adam Beynon(@adambeynon):@elia on a related note, I have made some changes to core lib to make it more “pick and choose” - can make corelib very light weight - I needed it for a site that needs to be as small as possible ---------------------------------------------------------------------------------------------------- [23:50:42] Adam Beynon(@adambeynon):require "opal-mini" ---------------------------------------------------------------------------------------------------- ############################## [2015-01-06] ############################## [00:02:56] Andrew Havens(@andrewhavens):hmm….just found the docs you were referring to… ---------------------------------------------------------------------------------------------------- [00:04:56] Andrew Havens(@andrewhavens):So I guess my question is, if I add the `opal` gem to the Gemfile of my Rails app, can I create a file like `app/assets/templates/myfile.erb` and reference it with `JST[‘myfile’]` ---------------------------------------------------------------------------------------------------- [00:07:18] Andrew Havens(@andrewhavens):…and pass some variables into the template: `JST[‘myfile’]({user: {name: ‘Andrew'}})` ---------------------------------------------------------------------------------------------------- [01:48:52] Can Edremitoglu(@cantonic):@andrewhavens afaik you cannot use JST, but opal has a `Template` class which does what you need. Look here: http://opalrb.org/docs/templates/ ---------------------------------------------------------------------------------------------------- [01:49:10] Can Edremitoglu(@cantonic):@andrewhavens By the way: i am also switching from backbone to opal currently ---------------------------------------------------------------------------------------------------- [11:00:45] Bernhard Weichel(@bwl21): ---------------------------------------------------------------------------------------------------- [11:01:08] Bernhard Weichel(@bwl21):There is a class "JsonErrorx" and I cannot find out where it comes from ... ---------------------------------------------------------------------------------------------------- [18:46:12] Jared White(@jaredcwhite):@andrewhavens Yes, it's very easy to use erb templates using the Template class in Opal. I'm doing exactly that on a project. :sparkles: ---------------------------------------------------------------------------------------------------- [18:47:21] Jared White(@jaredcwhite):Hey folks, excited to announce the first public release of my new gem Shimmer. https://github.com/jaredcwhite/opal-shimmer ---------------------------------------------------------------------------------------------------- [18:47:50] Jared White(@jaredcwhite):it provides an easy, "Hashie"-like way to set and load values, use nested namespaces, and even persist values across browser sessions using localStorage. Soon, I will add an observer feature so you can hook into configuration value changes to update UI in real-time, etc. ---------------------------------------------------------------------------------------------------- [19:05:26] Can Edremitoglu(@cantonic):Hi there. I try to render a haml template with opal, but keep getting `parse error on value "." (tDOT) :form_modal:1`. Does anyone have an idea what the problem could be? ---------------------------------------------------------------------------------------------------- [20:10:09] Adam Beynon(@adambeynon):@cantonic can you gist your haml file? (or maybe just a part of it which fails so I can try here) ---------------------------------------------------------------------------------------------------- [20:37:14] Can Edremitoglu(@cantonic):@adambeynon: I just added `.foobar` to it ---------------------------------------------------------------------------------------------------- [20:38:13] Can Edremitoglu(@cantonic):@adambeynon but i will put together a gist of all files involved ---------------------------------------------------------------------------------------------------- [20:59:31] Can Edremitoglu(@cantonic):@adambeynon https://gist.github.com/cantonic/448eac317b518bed5b8a ---------------------------------------------------------------------------------------------------- [22:37:51] Can Edremitoglu(@cantonic):when I change `.foobar` to `#foobar` it doesn’t complain anymore. using dots for defining element classes in the HAML way seems to not work ---------------------------------------------------------------------------------------------------- [22:42:58] Can Edremitoglu(@cantonic):@adambeynon Using opal-haml from github instead of rubygems solved the problem ---------------------------------------------------------------------------------------------------- [23:27:03] Andrew Havens(@andrewhavens):@cantonic Interesting…what was the diff between versions? ---------------------------------------------------------------------------------------------------- [23:44:20] Can Edremitoglu(@cantonic):@andrewhavens https://github.com/opal/opal-haml/compare/ea15b55999b1e6e1fbf8f0264e2a3dd9bb377b20...master … but I am not sure which change fixed that problem.

Maybe that should be in a PR for the opal native module? ---------------------------------------------------------------------------------------------------- [15:03:22] CJ Lazell(@cj):@sleewoo looks awesome, thank you. I'll try it out today :) ---------------------------------------------------------------------------------------------------- [15:08:37] Slee Woo(@sleewoo):yeah, saying Opal is pretty awesome it is to say nothing. it is monumental :) ---------------------------------------------------------------------------------------------------- [15:41:45] Slee Woo(@sleewoo):@jaredcwhite, did not think about ---------------------------------------------------------------------------------------------------- [15:42:00] Slee Woo(@sleewoo):let’s ask gurus :) ---------------------------------------------------------------------------------------------------- [15:43:00] Slee Woo(@sleewoo):@adambeynon, @elia does it makes sense to have something like this in

'`function` does not accept arguments') block || raise(ArgumentError, 'block required') proc do |*a| a.map! {|x| Native(`x`)} instance = Native(`this`) %x{ (function() { var bs = block.$$s; block.$$s

Woo(@sleewoo):https://gist.github.com/sleewoo/8d785061fc0cfbe5675d ---------------------------------------------------------------------------------------------------- [15:57:27] CJ Lazell(@cj):@sleewoo so I have, https://gist.github.com/03229378e5f05b0b7a1a still not working yet, I'm getting `Uncaught TypeError: no implicit conversion of NilClass into String` I'm debugging it right now to see what it could be ---------------------------------------------------------------------------------------------------- [15:58:49] Slee Woo(@sleewoo):not sure `escape(item.name)` may work ---------------------------------------------------------------------------------------------------- [15:58:55] Slee Woo(@sleewoo):try `escape.call(item.name)` ---------------------------------------------------------------------------------------------------- [16:02:45] CJ Lazell(@cj):@sleewoo that led to a different error to do with the plugin itself http://i.imgur.com/zQRBpiL.png, which I'm guessing it means it's not returning correctly ---------------------------------------------------------------------------------------------------- [16:05:13] Slee Woo(@sleewoo):@cj, try put ``debugger;`` inside one of that `function` and see what `item` and `escape` are ---------------------------------------------------------------------------------------------------- [16:06:38] Slee Woo(@sleewoo):https://gist.github.com/sleewoo/58f98ac9e1804dafab7a ---------------------------------------------------------------------------------------------------- [16:07:30] Slee Woo(@sleewoo):it will stop the universe just in the place you inserted debugger and you’ll can access `item` by `self.$item` in console ---------------------------------------------------------------------------------------------------- [16:09:34] CJ Lazell(@cj):@sleewoo it doesn't even seem to be getting in there ---------------------------------------------------------------------------------------------------- [16:10:36] Slee Woo(@sleewoo):then it’s not the function :) ---------------------------------------------------------------------------------------------------- [16:11:17] CJ Lazell(@cj):if I put the raw code in in `%x{}` it works just fine though ---------------------------------------------------------------------------------------------------- [16:12:37] Slee Woo(@sleewoo):oh, try without `to_n`, that’s for cases when you insert the hash directly into js ---------------------------------------------------------------------------------------------------- [16:15:46] CJ Lazell(@cj):@sleewoo ok, so no error now. it's turning the select into a selectizie but the functions are just not executed ---------------------------------------------------------------------------------------------------- [16:18:15] Slee Woo(@sleewoo):weird :) ---------------------------------------------------------------------------------------------------- [16:20:00] CJ Lazell(@cj):@sleewoo http://i.imgur.com/C2uLRls.png is never triggered but the other puts are ---------------------------------------------------------------------------------------------------- [16:22:26] Slee Woo(@sleewoo):@cj, try replace `function { |item…` with `proc { |item…` and see either it is executed ---------------------------------------------------------------------------------------------------- [16:22:43] Slee Woo(@sleewoo):if not it’s just not called by the plugin ---------------------------------------------------------------------------------------------------- [16:25:42] CJ Lazell(@cj):yee, it's never triggered ---------------------------------------------------------------------------------------------------- [16:27:02] CJ Lazell(@cj):@sleewoo it's only called if I add .to_n, but then I'm back to getting the other errors ---------------------------------------------------------------------------------------------------- [16:28:11] CJ Lazell(@cj):so adding to_n gets inside the proc, but it never executes the code inside the `function` ---------------------------------------------------------------------------------------------------- [16:36:47] CJ Lazell(@cj):@sleewoo so removing `block.$$s = null;` from your method now gets inside `function` and I can console.log item values and they are correct but it says escape doesn't exist

Even on your website I can just pop open the javascript console and use it, every Volt or Rails app using Opal I've tried just gets undefined, and nothing happens when you require the parser - or it blows up. ---------------------------------------------------------------------------------------------------- [22:14:16] Luke Barbuto(@lexun):I thought maybe it was a version thing, but I can `require 'opal-parser'` from irb just fine, it just doesn't seem to work in the browser for some reason ---------------------------------------------------------------------------------------------------- [22:14:29] Luke Barbuto(@lexun):Except for on opalrb.org lol ---------------------------------------------------------------------------------------------------- [22:15:47] Elia Schito(@elia):well, the parser is the heavist piece and it's not part of the corelib by default ---------------------------------------------------------------------------------------------------- [22:16:41] Luke Barbuto(@lexun):ahhh, this sounds like the info I've been searching for ---------------------------------------------------------------------------------------------------- [22:16:46] Elia Schito(@elia):opalrb.org should work with a simple sprockets environment, don't see why it shouldn't work in rails or volt ---------------------------------------------------------------------------------------------------- [22:17:44] Luke Barbuto(@lexun):I'm just working on something similar to try opal, but with running specs ---------------------------------------------------------------------------------------------------- [22:17:51] Luke Barbuto(@lexun):I see you had something very similar in opalrb.org ---------------------------------------------------------------------------------------------------- [22:18:37] Luke Barbuto(@lexun):How would I go about getting the parser included into the corelib, so overriding the default? ---------------------------------------------------------------------------------------------------- [22:19:17] Elia Schito(@elia):you should `require "opal-parser"` in your app code ---------------------------------------------------------------------------------------------------- [22:21:54] Luke Barbuto(@lexun):Hmm, for some reason that doesn't seem to work in my Volt project - but maybe I don't even need to do this anyway.... The whole point was to try to compile the user input ruby and eval it with javascript to try to simulate another process - so as the specs are run over and over and code changes it doesn't pollute the loaded classes. ---------------------------------------------------------------------------------------------------- [22:23:46] Luke Barbuto(@lexun):Would that even work though?

It wasn't really possible then, but I figured I would get your thoughts again. So with volt there's some file that I'm requiring by convention (instead of having an explicit require) So I almost need a way that I can have a url that when hit returns a list of required files as if it was hitting a file with a bunch of requires in it. I would just put a ton of .js files on the page, but it takes the browsers way longer to process and results in a lot more requests (even in dev its a big performance hit) ---------------------------------------------------------------------------------------------------- [22:00:12] Ryan Stout(@ryanstout):does that make any since? ---------------------------------------------------------------------------------------------------- [22:06:15] Ryan Stout(@ryanstout):like is there somewhere I could patch into the code that "reads" a file and just return my own code? (that requires in the main files) Right now I'm just reading the files I need myself for components then doing Opal.compile, but thats not great because it doesn't support source maps ---------------------------------------------------------------------------------------------------- [22:09:13] Adam Beynon(@adambeynon):@ryanstout not sure I completely understand. For example, if foo_controller.rb gets required, volt would also want a foo_view.rb, if it exists? (just as an example) ---------------------------------------------------------------------------------------------------- [22:11:01] Ryan Stout(@ryanstout):so its a bit complicated, basically in volt there are components, which is a mix of server and client code, and assets. One component can require another by name in a dependencies.rb file. And components might be in gems also. So basically I need a way to programmatically require in things from volt code without the user needing to use require directly. ---------------------------------------------------------------------------------------------------- [22:11:35] Ryan Stout(@ryanstout):does that help explain it? ---------------------------------------------------------------------------------------------------- [22:11:41] Ryan Stout(@ryanstout):sorry, kind of hard to explain ---------------------------------------------------------------------------------------------------- [22:11:55] Adam Beynon(@adambeynon):@ryanstout right, ok. I get it now ---------------------------------------------------------------------------------------------------- [22:12:08] Adam Beynon(@adambeynon):I think this is similar to what I want to do for opal-0.8 ---------------------------------------------------------------------------------------------------- [22:12:30] Adam Beynon(@adambeynon):I’ve been thinking about making Opal::Builder use some manifest type file ---------------------------------------------------------------------------------------------------- [22:12:34] Adam Beynon(@adambeynon):Opalfile for example ---------------------------------------------------------------------------------------------------- [22:12:39] Ryan Stout(@ryanstout):can you think of a good way to patch it in in the mean time? ---------------------------------------------------------------------------------------------------- [22:12:42] Adam Beynon(@adambeynon):to control what gets compiled ---------------------------------------------------------------------------------------------------- [22:12:53] Ryan Stout(@ryanstout):my problem is it needs to actually run volt code to decide what gets compiled ---------------------------------------------------------------------------------------------------- [22:13:19] Ryan Stout(@ryanstout):because it depends on a bunch of files with its own require dsl ---------------------------------------------------------------------------------------------------- [22:13:38] Adam Beynon(@adambeynon):@ryanstout would the code it runs also get run client side? ---------------------------------------------------------------------------------------------------- [22:13:51] Ryan Stout(@ryanstout):no, just the server to decide which files to send to the client ---------------------------------------------------------------------------------------------------- [22:14:31] Adam Beynon(@adambeynon):@ryanstout ok, well for 0.8 this will be easy, it will be able to hook into a revamped Builder, instead of using an Opalfile ---------------------------------------------------------------------------------------------------- [22:14:34] Adam Beynon(@adambeynon):for 0.7 though ---------------------------------------------------------------------------------------------------- [22:14:40] Adam Beynon(@adambeynon):I guess it is possible ---------------------------------------------------------------------------------------------------- [22:14:50] Adam Beynon(@adambeynon):does volt use Opal::Builder currently? ---------------------------------------------------------------------------------------------------- [22:15:00] Adam Beynon(@adambeynon):(sorry, havent managed to keep track with volt internals) ---------------------------------------------------------------------------------------------------- [22:15:01] Ryan Stout(@ryanstout):no, but it could ---------------------------------------------------------------------------------------------------- [22:15:05] Ryan Stout(@ryanstout):no worries ---------------------------------------------------------------------------------------------------- [22:17:48] Adam Beynon(@adambeynon):@ryanstout let me have a think about it. it is something I want to be able to support with opal 0.7, which would then go on to influence the changes for 0.8 ---------------------------------------------------------------------------------------------------- [22:17:59] Adam Beynon(@adambeynon):it probably easier with volt as you’re not using sprockets directly ---------------------------------------------------------------------------------------------------- [22:18:14] Adam Beynon(@adambeynon):bit more flexability for handling the compile chain ---------------------------------------------------------------------------------------------------- [22:18:24] Ryan Stout(@ryanstout):yea, I mean I'm using sprockets for a few things ---------------------------------------------------------------------------------------------------- [22:18:52] Ryan Stout(@ryanstout):so what is Opal::Builder used for? ---------------------------------------------------------------------------------------------------- [22:20:09] Adam Beynon(@adambeynon):You give Opal::Builder a single file name, which should be inside the opal load path, and then it will go through the code, compiling every dependency it can find for that file (via #require statements), and gives you back a long string of compiled javascript and a source map for it ---------------------------------------------------------------------------------------------------- [22:20:29] Adam Beynon(@adambeynon):but, it only currently handles hard coded require and require_tree statements ---------------------------------------------------------------------------------------------------- [22:21:42] Adam Beynon(@adambeynon):Opal::Builder.build(“application”) is the simple rake task I use for building my apps for production (when not using rails asset pipeline) ---------------------------------------------------------------------------------------------------- [22:26:06] Adam Beynon(@adambeynon):@ryanstout https://gist.github.com/adambeynon/4feee9cb0a282a513203 ---------------------------------------------------------------------------------------------------- [22:26:16] Adam Beynon(@adambeynon):that is something that I have in my head for what I want ---------------------------------------------------------------------------------------------------- [22:26:24] Ryan Stout(@ryanstout):yea, that would be awesome ---------------------------------------------------------------------------------------------------- [22:26:26] Adam Beynon(@adambeynon):but volt could generate something automatically ---------------------------------------------------------------------------------------------------- [22:26:59] Ryan Stout(@ryanstout):in the mean time you think I could just patch where it reads a file and have it return the code as if it was in a file that required in everything? ---------------------------------------------------------------------------------------------------- [22:27:42] Adam Beynon(@adambeynon):@ryanstout yes, I think that can work ---------------------------------------------------------------------------------------------------- [22:29:23] Adam Beynon(@adambeynon):@ryanstout will give it some thought in the morning ---------------------------------------------------------------------------------------------------- [22:29:33] Ryan Stout(@ryanstout):cool, thanks a bunch ---------------------------------------------------------------------------------------------------- [22:29:39] Ryan Stout(@ryanstout):sorry, I realize this isn't a normal use case ---------------------------------------------------------------------------------------------------- [22:29:39] Adam Beynon(@adambeynon):I will also spend some time inside volt’s source to see how you’re doing compiling etc now ---------------------------------------------------------------------------------------------------- [22:30:01] Ryan Stout(@ryanstout):right now the compiling for components is just reading the files and doing Opal.compile ---------------------------------------------------------------------------------------------------- [22:30:19] Ryan Stout(@ryanstout):the framework its self's code is just on the asset_path ---------------------------------------------------------------------------------------------------- [22:30:41] Ryan Stout(@ryanstout):I'm hoping just generating something with requires will simplify things. ---------------------------------------------------------------------------------------------------- [22:52:00] Ryan Stout(@ryanstout):@adambeynon also, I can add in caching if you can point me in the right direction. Not having it really slows things down for volt, so I'll do anything I can to get it back in :-) ---------------------------------------------------------------------------------------------------- [00:47:55] Can Edremitoglu(@cantonic):wow,really great news ---------------------------------------------------------------------------------------------------- [21:40:14] Ryan Stout(@ryanstout):random question, would it be possible in the future to make ```require_tree``` take a glob pattern? ---------------------------------------------------------------------------------------------------- [21:42:45] Adam Beynon(@adambeynon):@ryanstout yeap. we opted for a sprockets friendly tree for the initial implementation, but for 0.8 the plan is to use sprockets purely as an entry point, so things like require_tree will become much better suited ---------------------------------------------------------------------------------------------------- [21:42:57] Adam Beynon(@adambeynon):so yes, globs are the plan ---------------------------------------------------------------------------------------------------- [21:43:16] Adam Beynon(@adambeynon):(but they still need to belong to the opal load path) ---------------------------------------------------------------------------------------------------- [21:43:24] Ryan Stout(@ryanstout):@adambeynon ok, cool. Yea, that makes since. ---------------------------------------------------------------------------------------------------- [21:44:37] Ryan Stout(@ryanstout):is it something I could monkey-patch in in the mean time? (not sure if thats a good idea, just thinking through options) ---------------------------------------------------------------------------------------------------- [21:45:20] Adam Beynon(@adambeynon):@ryanstout it should be possible. you will need something in the runtime.js to support it as well ---------------------------------------------------------------------------------------------------- [21:45:28] Ryan Stout(@ryanstout):ok ---------------------------------------------------------------------------------------------------- [21:45:41] Adam Beynon(@adambeynon):a simple glob => regexp type thing should be enough to check against each Opal.module entry ---------------------------------------------------------------------------------------------------- [21:45:41] Ryan Stout(@ryanstout):let me think through a few things then :-) ---------------------------------------------------------------------------------------------------- ############################## [2015-02-24] ############################## [22:35:55] Ryan Stout(@ryanstout):@adambeynon you around? ---------------------------------------------------------------------------------------------------- ############################## [2015-02-25] ############################## [10:55:08] Adam Beynon(@adambeynon):hi @ryanstout, im here for the next few hours if you’re about (not sure what the time difference is between us ;) ) ---------------------------------------------------------------------------------------------------- [10:55:38] Elia Schito(@elia):probably still asleep :) ---------------------------------------------------------------------------------------------------- [11:19:59] Elia Schito(@elia):@krainboltgreene, https://github.com/krainboltgreene/hackerlife/blob/master/lib/hacklife/terminal.rb#L1 mispelled :D ---------------------------------------------------------------------------------------------------- [11:20:26] Elia Schito(@elia):*misspelled ---------------------------------------------------------------------------------------------------- [17:18:56] Elia Schito(@elia):@adambeynon, still early, but seems to work more or less: https://gist.github.com/elia/e330d92d8b826d089c4f ---------------------------------------------------------------------------------------------------- [17:52:54] Ryan Stout(@ryanstout):@elia whats that last code for? ---------------------------------------------------------------------------------------------------- [18:10:27] ylluminate(@ylluminate):@elia it's too bad that the react wrapper was done as it is.

I always end up mixing and matching js coffee and opal, plus maybe erb etc. ---------------------------------------------------------------------------------------------------- [08:57:03] Elia Schito(@elia):also that would help in isolating sourcemaps per file, thus making them slower but more precise ---------------------------------------------------------------------------------------------------- [08:58:02] Elia Schito(@elia):@adambeynon that knowing that I could probably fix everything given enough time, which I don't have :smile_cat: ---------------------------------------------------------------------------------------------------- [08:59:50] Adam Beynon(@adambeynon):@elia time is the problem :D so, just to check, are you on about going back to a more standard sprockets based setup? and letting sprockets handle everything? ---------------------------------------------------------------------------------------------------- [09:02:07] Elia Schito(@elia):that's the idea, or let's say at least give chioce ---------------------------------------------------------------------------------------------------- [09:02:29] Elia Schito(@elia):it's surely easier than supporting every possible sprockets extension combination ---------------------------------------------------------------------------------------------------- [09:03:01] Elia Schito(@elia):would also be easier to understand for a sprockets user (con is the Opal.load part of course) ---------------------------------------------------------------------------------------------------- [09:04:23] Elia Schito(@elia):@adambeynon but for `Opal.load` I was thinking about overloading `javascripts_include_tag` to add Opal.load if Opal is defined and 'application' is a module ---------------------------------------------------------------------------------------------------- [09:05:29] Elia Schito(@elia):@adambeynon but I want to hear your opinion on this… ---------------------------------------------------------------------------------------------------- [09:05:34] Elia Schito(@elia):btw the source map fixing branch seem to work fine for serving them correctly, but the contents are still messed up ---------------------------------------------------------------------------------------------------- [09:18:03] Adam Beynon(@adambeynon):@elia for convenience, I think this is a good way to go. agreed with overriding the script tag as well. I do have some time tomorrow, so I can spend a couple of hours looking through the current code and seeing how things will pan out ---------------------------------------------------------------------------------------------------- [09:18:47] Elia Schito(@elia):@adambeynon thanks, I'll push my initial code to a branch then ---------------------------------------------------------------------------------------------------- [09:19:23] Elia Schito(@elia):I think this would also benefit caching, cc @ryanstout ---------------------------------------------------------------------------------------------------- [09:19:38] Adam Beynon(@adambeynon)::+1: yes, that’s true ---------------------------------------------------------------------------------------------------- [09:20:17] Adam Beynon(@adambeynon):@elia I went to the Bath Ruby conference on the weekend, and got some interesting feedback into people who have looked at opal before, and why/how the havent used it ---------------------------------------------------------------------------------------------------- [09:20:28] Adam Beynon(@adambeynon):it all comes down to some misconceptions about how it works ---------------------------------------------------------------------------------------------------- [09:20:36] Elia Schito(@elia):@adambeynon Also I think it can be done just in the processor without affecting the builder which can than be freed from some "sprockets" burden ---------------------------------------------------------------------------------------------------- [09:20:49] Adam Beynon(@adambeynon):so, I am going to focus some time clearing the docs up, to avoid this confusion ---------------------------------------------------------------------------------------------------- [09:21:05] Elia Schito(@elia):@adambeynon awesome™! ---------------------------------------------------------------------------------------------------- [09:21:51] Elia Schito(@elia):alas, marketing is fundamental, few will go beyond first impression and "discover reality" ---------------------------------------------------------------------------------------------------- [09:22:25] Elia Schito(@elia):@adambeynon so I saw a prev tweet of you mentioning stickers, ever printed any? ---------------------------------------------------------------------------------------------------- [09:26:58] Elia Schito(@elia):@adambeynon https://github.com/opal/opal/tree/elia/wip-back-to-sprockets ---------------------------------------------------------------------------------------------------- [09:27:19] Elia Schito(@elia):it's based on https://github.com/opal/opal/tree/elia/source-maps-fix, which is probably time to merge ---------------------------------------------------------------------------------------------------- [10:05:14] Adam Beynon(@adambeynon):@elia nope, not done any printing before ---------------------------------------------------------------------------------------------------- [10:06:10] Elia Schito(@elia):@adambeynon will be glad to send a bunch of them once they're viable (last batch was on paper instead of vinyl) ---------------------------------------------------------------------------------------------------- [10:07:51] Adam Beynon(@adambeynon):@elia sure! I will save some space on my new retina macbook for one ;) ---------------------------------------------------------------------------------------------------- [10:08:08] Elia Schito(@elia)::D ---------------------------------------------------------------------------------------------------- [10:08:15] Elia Schito(@elia):13 or 15? ---------------------------------------------------------------------------------------------------- [10:08:41] Adam Beynon(@adambeynon):@elia my move from cordova -> WKWebView was going really well until WebSQL seems to be broken on WKWebView ---------------------------------------------------------------------------------------------------- [10:08:46] Adam Beynon(@adambeynon):@elia noooo, the NEW one ---------------------------------------------------------------------------------------------------- [10:08:47] Adam Beynon(@adambeynon):12 ---------------------------------------------------------------------------------------------------- [10:08:48] Adam Beynon(@adambeynon):http://www.apple.com/macbook/ ---------------------------------------------------------------------------------------------------- [10:09:03] Adam Beynon(@adambeynon):ultra portablz ---------------------------------------------------------------------------------------------------- [10:09:08] Elia Schito(@elia):@elia drops jaw ---------------------------------------------------------------------------------------------------- [10:09:36] Elia Schito(@elia):yeah watched the whole preso, already shipped? ---------------------------------------------------------------------------------------------------- [10:09:49] Elia Schito(@elia):@adambeynon is it good for development ---------------------------------------------------------------------------------------------------- [10:09:51] Elia Schito(@elia):? ---------------------------------------------------------------------------------------------------- [10:10:24] Adam Beynon(@adambeynon):April 10th I think, need to pre-order it. Im hoping the processor is ok for dev. I still run various rails stuff on the original macbook air, and thats fine ---------------------------------------------------------------------------------------------------- [10:10:33] Elia Schito(@elia):btw I got a 15 at new workplace but really a fan of 13" (or less) ---------------------------------------------------------------------------------------------------- [10:11:10] Adam Beynon(@adambeynon):ah I didn’t realise you moved work. Still ruby dev? ---------------------------------------------------------------------------------------------------- [10:11:17] Elia Schito(@elia):ok, know confess the color of choice :) ---------------------------------------------------------------------------------------------------- [10:11:29] Elia Schito(@elia):yes, still ruby, and more opal (thankfully) ---------------------------------------------------------------------------------------------------- [10:12:28] Adam Beynon(@adambeynon):woop! ---------------------------------------------------------------------------------------------------- [10:12:43] Elia Schito(@elia):@adambeynon ever tried leveldb & co instead of sql? (I didn't) ---------------------------------------------------------------------------------------------------- [10:12:44] Adam Beynon(@adambeynon):Im not brave enough for gold, going for a classic apple silver colour I think ---------------------------------------------------------------------------------------------------- [10:13:40] Elia Schito(@elia):heh, yeah, gold is for tough guys only… (or not? not sure here lol) ---------------------------------------------------------------------------------------------------- [12:26:27] Adam Beynon(@adambeynon):@elia I have been using optimised math operators in my app now since 0.7, I think we should enable it by default as discussed before ---------------------------------------------------------------------------------------------------- [12:26:34] Adam Beynon(@adambeynon):seems pretty sturdy ---------------------------------------------------------------------------------------------------- [12:57:13] Elia Schito(@elia)::+1: ---------------------------------------------------------------------------------------------------- [12:57:54] Elia Schito(@elia):@adambeynon at this point I wonder if it still makes sense to stay on 0.7 instead of bumping version to 0.8… ---------------------------------------------------------------------------------------------------- [12:58:14] Elia Schito(@elia):enough stuff has been added already imo ---------------------------------------------------------------------------------------------------- [13:00:51] Adam Beynon(@adambeynon):@elia sounds good to me :ok_hand: ---------------------------------------------------------------------------------------------------- [13:53:36] Elia Schito(@elia):I'll push a 0-7-stable branch from the latest release, just in case ---------------------------------------------------------------------------------------------------- [14:04:22] Adam Beynon(@adambeynon):@elia okies. As we work on the changes for sprockets etc, I think it would be a good idea to keep checking opal-rspec works well with it. That is a huge pain with requires, so it might be easier than going back retrospectively to fix new issues ---------------------------------------------------------------------------------------------------- [14:04:56] Elia Schito(@elia)::+1: ---------------------------------------------------------------------------------------------------- [20:15:59] Mitch VanDuyn(@catmando):Quick question (I hope)... I have a gem that I want to "opal-ize". I have tested the gem by copying its files to the javascript directory, as well as the test specs, and all is well. Is there a trick I can use to reference the "master" gem inside the "opal" gem? ---------------------------------------------------------------------------------------------------- [20:16:49] Mitch VanDuyn(@catmando):For now I am just copying the files over to the opal version, but long term obviously I don't want to do that! ---------------------------------------------------------------------------------------------------- [21:45:28] Mitch VanDuyn(@catmando):And actually if anybody wants to look, and see if did this right please do so: ---------------------------------------------------------------------------------------------------- [21:45:52] Mitch VanDuyn(@catmando):https://github.com/catprintlabs/opal-cannonbol ---------------------------------------------------------------------------------------------------- [21:46:53] Mitch VanDuyn(@catmando):It seems to work fine, but it also seems to be treating the files differently than the standard opal libraries. I am wondering if I am doing something wrong... I just stole the whole gem structure from opal-jquery... ---------------------------------------------------------------------------------------------------- [22:15:22] Elia Schito(@elia):@catmando struct seems right, you have any stacktrace or specific error? ---------------------------------------------------------------------------------------------------- [22:27:04] Kurtis Rainbolt-Greene(@krainboltgreene):Is there a good writeup on how to use third party js libraries inside opal? ---------------------------------------------------------------------------------------------------- [22:27:38] Kurtis Rainbolt-Greene(@krainboltgreene):Like, one function in javscript is function(FUNCTION, OPTIONS), but in Ruby that doesn't make sense as blocks are always the last argument.. ---------------------------------------------------------------------------------------------------- [22:27:53] Kurtis Rainbolt-Greene(@krainboltgreene):And it doesn't seem to work in reverse. ---------------------------------------------------------------------------------------------------- [22:30:23] Elia Schito(@elia):nope, but basically you have two strategies: bridging js classes (as opal-jquery does) or wrapping with Native(`jsObject`) ---------------------------------------------------------------------------------------------------- [22:34:00] Kurtis Rainbolt-Greene(@krainboltgreene):I see writing about using `expose` with other jquery plugins, but nothing so far on handling common js practices. ---------------------------------------------------------------------------------------------------- [22:34:36] Elia Schito(@elia):Opal::Browser is a great example of using native ---------------------------------------------------------------------------------------------------- [22:35:28] Elia Schito(@elia):@krainboltgreene https://duckduckgo.com/?q=opal+site:dev.mikamai.com&t=osx ---------------------------------------------------------------------------------------------------- [22:36:21] Kurtis Rainbolt-Greene(@krainboltgreene):Yeah, I've been reading that. ---------------------------------------------------------------------------------------------------- [22:39:07] Kurtis Rainbolt-Greene(@krainboltgreene):Okay, the opal-jquery has details on how to do HTTP requests, which has a similar arity to what I'm dealing with, but it seems like instead of passing a hash with functions (mirroring the js Object with functions) it's got a block, and then has setter properties. ---------------------------------------------------------------------------------------------------- [22:40:14] Kurtis Rainbolt-Greene(@krainboltgreene):Hmm not setters. ---------------------------------------------------------------------------------------------------- [22:47:28] Elia Schito(@elia):@krainboltgreene try with the Element#animate source, probably a better example iirc ---------------------------------------------------------------------------------------------------- [22:49:50] Kurtis Rainbolt-Greene(@krainboltgreene):Gotta say, the internal documentation for these projects is top notch. ---------------------------------------------------------------------------------------------------- [22:51:34] Kurtis Rainbolt-Greene(@krainboltgreene):Looks like jquery.terminal is just doing things wrong. ---------------------------------------------------------------------------------------------------- [22:51:46] Kurtis Rainbolt-Greene(@krainboltgreene):But I can use #animate to do my own thing. ---------------------------------------------------------------------------------------------------- [22:53:58] Kurtis Rainbolt-Greene(@krainboltgreene):@elia: Is there a way to see the ruby source of a method generated via expose? ---------------------------------------------------------------------------------------------------- [22:54:51] Elia Schito(@elia):expose uses the js function as is ---------------------------------------------------------------------------------------------------- [22:55:26] Elia Schito(@elia):so, say the function returns undefined it could give trouble ---------------------------------------------------------------------------------------------------- [22:59:10] Kurtis Rainbolt-Greene(@krainboltgreene):Woot! ---------------------------------------------------------------------------------------------------- [22:59:24] Kurtis Rainbolt-Greene(@krainboltgreene):It had something to do with the fact that I was using a Ruby hash. ---------------------------------------------------------------------------------------------------- [22:59:39] Kurtis Rainbolt-Greene(@krainboltgreene):As soon as I used `` to generate a JS Object the options were recognized. ---------------------------------------------------------------------------------------------------- [23:13:26] Kurtis Rainbolt-Greene(@krainboltgreene):Are there any Ruby native object to Javascript native object methods? ---------------------------------------------------------------------------------------------------- [23:14:06] Kurtis Rainbolt-Greene(@krainboltgreene):AKA: `{ "key" => "value" }.to_native == ```{ "key": "value" }```` ---------------------------------------------------------------------------------------------------- [23:14:41] Kurtis Rainbolt-Greene(@krainboltgreene)::| ---------------------------------------------------------------------------------------------------- [23:15:39] Elia Schito(@elia):require 'native' and #to_n ---------------------------------------------------------------------------------------------------- [23:15:48] Kurtis Rainbolt-Greene(@krainboltgreene):Awesome. ---------------------------------------------------------------------------------------------------- [23:15:55] Kurtis Rainbolt-Greene(@krainboltgreene):Thanks @elia. ---------------------------------------------------------------------------------------------------- ############################## [2015-03-19] ############################## [04:01:44] Mitch VanDuyn(@catmando):@elia re: opal-cannonbol, no errors, all tests pass. Its just seems like it is deliverying the code differently than say opal-jquery. opal-jquery comes down to the browser as a separate request, but opal-cannonbol seems to be bundled up inside the main app. ---------------------------------------------------------------------------------------------------- [04:22:44] Mitch VanDuyn(@catmando):@elia, I guess what I am not getting is what the difference is between what happens when you do a "rake release" on the cannonbol gem and the opal-cannonbol gem. Both directories look almost exactly the same, the only difference I can spot is the extra :dist rake task... does the release task somehow hook into this, to build the js file? How does this work (he said scratching his head, until he was bald :-) ---------------------------------------------------------------------------------------------------- [08:50:33] Elia Schito(@elia):@catmando `rake release` should be the vanilla gem building task from bundler (as in `bundle gem YOURNAME`) ---------------------------------------------------------------------------------------------------- [08:51:47] Elia Schito(@elia):@catmando can you explain how do you see they're different? (…browser requests, gem open, something else) seems something easily fixable anyway ---------------------------------------------------------------------------------------------------- [09:49:40] Elia Schito(@elia):@adambeynon I think I'm on the right way with requires and stuff ---------------------------------------------------------------------------------------------------- [09:50:53] Adam Beynon(@adambeynon):@elia nice! just checking out the commits now ---------------------------------------------------------------------------------------------------- [09:51:20] Elia Schito(@elia):right know I'm looking into opal-haml ---------------------------------------------------------------------------------------------------- [11:29:06] Elia Schito(@elia):@adambeynon I think it's done, just need to push the overridden javascript_include_tag to opal-rails ---------------------------------------------------------------------------------------------------- [11:29:23] Elia Schito(@elia):``` def javascript_include_tag(*sources) sources_copy = sources.dup.tap(&:extract_options!) sprockets = Rails.application.assets script_tags = super sources_copy.map do |source| loading_code = Opal::Processor.load_asset_code(sprockets, source) script_tags << javascript_tag(loading_code) end script_tags end ``` ---------------------------------------------------------------------------------------------------- [11:30:12] Elia Schito(@elia):_not sure why gitter messes up newlines :(_ ---------------------------------------------------------------------------------------------------- [11:49:04] Mitch VanDuyn(@catmando):@elia, Its NOT messing up! I just don't understand how it works. I see no dfference between a gem that runs the code on the server and a gem that runs the code in opal! The only differences I see is that opal is required in the gemspec (makes sense) and the rake file has this extra "dist" task. ---------------------------------------------------------------------------------------------------- [11:49:30] Mitch VanDuyn(@catmando):So how can the gem release process "know" to do the right thing with the code?? ---------------------------------------------------------------------------------------------------- [11:50:13] Elia Schito(@elia):@catmando I'll show you the trick in a moment… ---------------------------------------------------------------------------------------------------- [11:50:40] Elia Schito(@elia):https://github.com/opal/opal-jquery/blob/master/lib/opal/jquery.rb#L1 ---------------------------------------------------------------------------------------------------- [11:53:23] Mitch VanDuyn(@catmando):yeah i saw that, but i don't get it... let me look again... ---------------------------------------------------------------------------------------------------- [11:56:11] Mitch VanDuyn(@catmando):so basically let me get this: ---------------------------------------------------------------------------------------------------- [11:56:47] Mitch VanDuyn(@catmando):1) the gem puts all the files into the the gem package ---------------------------------------------------------------------------------------------------- [11:58:52] Mitch VanDuyn(@catmando):nah I don't get it at all. ---------------------------------------------------------------------------------------------------- [11:59:49] Mitch VanDuyn(@catmando):In one case the same files (in my case) are treated as normal files and run on the server, in the other case they become assets and served up... ---------------------------------------------------------------------------------------------------- [12:01:52] Adam Beynon(@adambeynon):@elia awesome! :metal: ---------------------------------------------------------------------------------------------------- [12:01:58] Mitch VanDuyn(@catmando):WAIT... so let me guess... there is NO difference, except that someplace some opal code does a "require opal-cannonbol", and that AUTOMAGICALLY grabs the right files, and compiles them ---------------------------------------------------------------------------------------------------- [12:02:13] Adam Beynon(@adambeynon):so for a static build, or non rails environment, we just need a manual Opal.load(‘application’) which does the bootstrapping? ---------------------------------------------------------------------------------------------------- [12:03:15] Elia Schito(@elia):@adambeynon yes, plus the mark_as_required when requiring unwrapped js files ---------------------------------------------------------------------------------------------------- [12:04:08] Elia Schito(@elia):(but corelib/runtime.js is already marked required) ---------------------------------------------------------------------------------------------------- [12:04:45] Elia Schito(@elia):@adambeynon also the Builder still works as before ---------------------------------------------------------------------------------------------------- [12:05:32] Elia Schito(@elia):@catmando the code I linked requires different files basing on the fact that it's inside opal or inside MRI ---------------------------------------------------------------------------------------------------- [12:06:29] Elia Schito(@elia):@catmando also Opal considers `if RUBY_ENGINE == 'opal'` in a special way, discarding the else part entirely ---------------------------------------------------------------------------------------------------- [12:07:39] Elia Schito(@elia):@adambeynon should we try rspec on it and merge? I think stubs still need to be forwarded to sprockets… ---------------------------------------------------------------------------------------------------- [12:08:05] Elia Schito(@elia):_lunchtime! :spaghetti:_ ---------------------------------------------------------------------------------------------------- [12:08:11] Mitch VanDuyn(@catmando):@elia, yes understood... that is the same code in my gem (stolen from this file in fact.) Understand that it includes different things depending... Just did not quite believe the magic that lets opal get the files compiled etc. just because they are there... I guess I would like to understand better! ---------------------------------------------------------------------------------------------------- [12:08:27] Mitch VanDuyn(@catmando):@elia... COFFEE TIME... sun just rose here :-) ---------------------------------------------------------------------------------------------------- [12:47:32] Elia Schito(@elia):@catmando whoa, what time exactly? ---------------------------------------------------------------------------------------------------- [12:48:37] Elia Schito(@elia):@catmando sorry if I restate stuff you know already, maybe the missing piece is that opal parses all require statements and precompiles all required files statically so they're ready for when they'll actually be required ---------------------------------------------------------------------------------------------------- [16:03:18] Mitch VanDuyn(@catmando):@elia, no problem. Here is what I am not understanding: ---------------------------------------------------------------------------------------------------- [16:10:21] Mitch VanDuyn(@catmando):I am not seeing how the following lines work ---------------------------------------------------------------------------------------------------- [16:10:25] Mitch VanDuyn(@catmando): ---------------------------------------------------------------------------------------------------- [16:10:46] Mitch VanDuyn(@catmando):if RUBY_ENGINE == 'opal' require 'opal/cannonbol/cannonbol' else require 'opal' require 'opal/cannonbol/version' Opal.append_path File.expand_path('../..', __FILE__).untaint end ---------------------------------------------------------------------------------------------------- [16:12:27] Elia Schito(@elia):if the ruby engine is opal it requires the code that should run in the browser ---------------------------------------------------------------------------------------------------- [16:13:12] Elia Schito(@elia):otherwise it will add the gem lib folder to the paths the opal compiler will look into (this happens in MRI/CRuby, not in the browser) ---------------------------------------------------------------------------------------------------- [16:13:29] Elia Schito(@elia):@catmando does it help? ---------------------------------------------------------------------------------------------------- [16:14:12] Mitch VanDuyn(@catmando):right, so when I do a require 'opal-cannonbol' in a .js.rb file in my assets folder, that is running with RUBY_ENGINE=='opal' correct? ---------------------------------------------------------------------------------------------------- [16:14:22] Elia Schito(@elia):yep ---------------------------------------------------------------------------------------------------- [16:14:48] Mitch VanDuyn(@catmando):So here is what my other "non" opal file looks like: ---------------------------------------------------------------------------------------------------- [16:15:12] Mitch VanDuyn(@catmando):well it just has the ruby code in it, no require or anything ---------------------------------------------------------------------------------------------------- [16:15:27] Mitch VanDuyn(@catmando):so lets say instead of the above code, i just had: ---------------------------------------------------------------------------------------------------- [16:15:34] Mitch VanDuyn(@catmando):puts 'hello world' ---------------------------------------------------------------------------------------------------- [16:16:42] Mitch VanDuyn(@catmando):i.e. my whole gem just consists of 1 line: ---------------------------------------------------------------------------------------------------- [16:16:48] Mitch VanDuyn(@catmando):puts 'hello world' ---------------------------------------------------------------------------------------------------- [16:17:30] Mitch VanDuyn(@catmando):sorry, I am not being clear...

My guess is that opal doesn't compile the file, so the spec runner doesn't run it. ---------------------------------------------------------------------------------------------------- [00:32:53] Forrest Chang(@fkchang):Now that I described it, I guess I could check that compiled files match spec files, but not certain if I can catch the compile error ---------------------------------------------------------------------------------------------------- [12:02:53] Mitch VanDuyn(@catmando):@elia, that doc page is in a pull request I just made... ---------------------------------------------------------------------------------------------------- [12:26:41] Adam Beynon(@adambeynon):@catmando looks great!

I don't want to overlap if anybody has already submitted a talk on Opal... ---------------------------------------------------------------------------------------------------- [15:31:40] Mitch VanDuyn(@catmando):But I am figuring no, since a lot of folks are not close to NYC :-) ---------------------------------------------------------------------------------------------------- [15:32:33] Elia Schito(@elia):I'm quite sure I won't make it :P ---------------------------------------------------------------------------------------------------- [15:35:35] Mitch VanDuyn(@catmando):Well then if nobody has an objection, I will submit a proposal anyway. I am sure its pretty competitive to get in, so wish me luck :-) ---------------------------------------------------------------------------------------------------- [15:45:00] Mitch VanDuyn(@catmando):Okay, here is my draft of talk, please let me know if this sounds appealing, as I think it will help Opal's visibility, if I can get accepted as a speaker. (its a 30 minute talk) ---------------------------------------------------------------------------------------------------- [15:45:32] Mitch VanDuyn(@catmando):Opal is a Ruby to Javascript compiler that is rapidly maturing. We have about 1 million lines of code running our website and manufacturing backend. The code is all ruby with the exception of Javascript. Opal opens a path to making our code base 100% pure ruby with the obvious benefits of having a single development language. This talk will give a brief overview of Opal, and its current status, and then will focus on our experience using Opal in a production environment, with emphasis on doing an evolutionary transition. ---------------------------------------------------------------------------------------------------- [15:46:07] Mitch VanDuyn(@catmando):. ---------------------------------------------------------------------------------------------------- [15:46:12] Mitch VanDuyn(@catmando):. ---------------------------------------------------------------------------------------------------- [15:59:03] Elia Schito(@elia):@catmando I think that seeing someone using it in production will make people more comfortable in trying it in they're own projects :+1: ---------------------------------------------------------------------------------------------------- [16:16:12] Mitch VanDuyn(@catmando):good... I am so appreciative of the teams work on Opal. ---------------------------------------------------------------------------------------------------- [16:17:55] Mitch VanDuyn(@catmando):I found it to be almost flawless. I found just a few issues with pretty obscure stuff, and the source mapping is rough. However the ability to use rspec and TDD makes up for that. ---------------------------------------------------------------------------------------------------- [16:19:18] Mitch VanDuyn(@catmando):It might be good to have some kind of gist collection of real world classes etc. I have a couple that are not quite ready to be gems, but might make useful examples. ---------------------------------------------------------------------------------------------------- [16:20:59] Mitch VanDuyn(@catmando):The Cannonbol gem I just released runs on opal with just a couple of changes (all documented as issues), and it does some heavy duty meta programming. I was really impressed. ---------------------------------------------------------------------------------------------------- [16:30:29] Elia Schito(@elia):great to hear that, also good source mapping is on its way back to opal ---------------------------------------------------------------------------------------------------- [16:44:57] Mitch VanDuyn(@catmando):Yeah I did a pull requests with some basic fixes, but I think its waiting for me to go back and do a bit more work, or perhaps somebody else is working the issue. ---------------------------------------------------------------------------------------------------- [16:45:19] Elia Schito(@elia)::) I am ---------------------------------------------------------------------------------------------------- ############################## [2015-03-21] ############################## [00:02:37] Elia Schito(@elia):@fkchang @catmando :+1: the more proposals the better ---------------------------------------------------------------------------------------------------- [23:03:54] Kurtis Rainbolt-Greene(@krainboltgreene):@adambeynon: Hey, I'd like to improve vienna. What are some of the sore points? ---------------------------------------------------------------------------------------------------- ############################## [2015-03-23] ############################## [04:53:25] Kurtis Rainbolt-Greene(@krainboltgreene):Would there be a way for opal to check gems for metadata in a gemspec to see if it's compatible with opal.rb? ---------------------------------------------------------------------------------------------------- [04:54:06] Kurtis Rainbolt-Greene(@krainboltgreene):That way gem owners can mark their gem as opal-compatible. ---------------------------------------------------------------------------------------------------- [09:16:27] Elia Schito(@elia):@adambeynon I think the back-to-sprockets branch is good (both for opal and opal-rails, which implies opal-rspec) ---------------------------------------------------------------------------------------------------- [09:21:48] Adam Beynon(@adambeynon):@elia nice one! So opal-rails overrides the script tag helper? ---------------------------------------------------------------------------------------------------- [09:22:38] Elia Schito(@elia):yep, but the code loading generation is delegated to Processor so it should be easy to use the code elsewhere (sinatra etc) ---------------------------------------------------------------------------------------------------- [09:22:45] Elia Schito(@elia):@adambeynon ---------------------------------------------------------------------------------------------------- [09:23:08] Adam Beynon(@adambeynon):@elia ah, thats good. Does it fix the sourcemaps issues, or shall I take a look at that? ---------------------------------------------------------------------------------------------------- [09:23:41] Elia Schito(@elia):They seem to be fixed, apprently having clear boundaries between files helps a lot ---------------------------------------------------------------------------------------------------- [09:24:15] Elia Schito(@elia):@adambeynon I guess we'll just wait for sprockets 4 to get them merged into a single map ---------------------------------------------------------------------------------------------------- [09:24:54] Elia Schito(@elia):right now was about to give a try to the sprockets 3 beta10 (quasi rc1) ---------------------------------------------------------------------------------------------------- [09:25:06] Adam Beynon(@adambeynon):@elia ahhh I see. Yeah, working closer with sprockets on that should make it a bit more robust. I figure they will be pouring lots of work into it for es6 and coffeescript support ---------------------------------------------------------------------------------------------------- [09:25:41] Elia Schito(@elia):@adambeynon yep, who needs to ewinvent the wheel after all :) ---------------------------------------------------------------------------------------------------- [09:27:54] Adam Beynon(@adambeynon):@elia ha, yeap ---------------------------------------------------------------------------------------------------- [09:27:56] Adam Beynon(@adambeynon):@elia https://github.com/opal/opal-rails/pull/40/files ---------------------------------------------------------------------------------------------------- [09:28:04] Adam Beynon(@adambeynon):I can’t see where you override the script helper? ---------------------------------------------------------------------------------------------------- [09:28:10] Adam Beynon(@adambeynon):am I just being blind? ---------------------------------------------------------------------------------------------------- [09:28:26] Elia Schito(@elia):never opened a PR, and even called the branch WIP ---------------------------------------------------------------------------------------------------- [09:28:33] Adam Beynon(@adambeynon):ohhhhhh ---------------------------------------------------------------------------------------------------- [09:28:48] Adam Beynon(@adambeynon):right, makes sense ---------------------------------------------------------------------------------------------------- [09:29:35] Elia Schito(@elia):https://github.com/opal/opal-rails/pull/43 ---------------------------------------------------------------------------------------------------- [09:31:32] Elia Schito(@elia):@adambeynon https://github.com/opal/opal/pull/773 ---------------------------------------------------------------------------------------------------- [09:36:04] Adam Beynon(@adambeynon):@elia :metal: fantastic! ---------------------------------------------------------------------------------------------------- [09:36:22] Adam Beynon(@adambeynon):it all looks good to me, so merge it :+1: ---------------------------------------------------------------------------------------------------- [09:36:52] Adam Beynon(@adambeynon):@elia Im going to merge in the template variables pull request as well later, makes templating a lot more convenient ---------------------------------------------------------------------------------------------------- [09:37:02] Elia Schito(@elia):@adambeynon let's rock then! :) ---------------------------------------------------------------------------------------------------- [09:43:14] Elia Schito(@elia):@adambeynon both merged 🎉 ---------------------------------------------------------------------------------------------------- [09:53:56] Adam Beynon(@adambeynon):@elia :clap: woop! Going to upgrade to this today I hope, was really missing the source maps ---------------------------------------------------------------------------------------------------- [09:54:14] Adam Beynon(@adambeynon):@elia Do you think 0.8 is close? there are some good changes since 0.7 ---------------------------------------------------------------------------------------------------- [09:54:26] Elia Schito(@elia):I do ---------------------------------------------------------------------------------------------------- [09:54:58] Elia Schito(@elia):@adambeynon we'll have to do the usual round up for open issues first tho ---------------------------------------------------------------------------------------------------- [09:55:27] Elia Schito(@elia):especially those marked 0.8, probably pushing them to next release ---------------------------------------------------------------------------------------------------- [09:55:51] Adam Beynon(@adambeynon):@elia yeap. Just working on some last minute code here, but I will take a good look later today at what is open atm, and give the new sprockets stuff a thorough testing. ---------------------------------------------------------------------------------------------------- [09:56:06] Adam Beynon(@adambeynon):and opal-rspec, to ensure that still works ok ---------------------------------------------------------------------------------------------------- [09:56:09] Elia Schito(@elia):@adambeynon :+1: ---------------------------------------------------------------------------------------------------- [17:56:13] Can Edremitoglu(@cantonic):hmm… I just upgraded opal and opal-rails to the latest master version and now I keep getting `Uncaught TypeError: Cannot set property '$$p' of undefined` for a file which only contains a simple `alert` function ---------------------------------------------------------------------------------------------------- [17:58:02] Elia Schito(@elia):Try deleting tmp/cache/assets and restart the app (and spring) ---------------------------------------------------------------------------------------------------- [17:58:10] Can Edremitoglu(@cantonic):alright… turns out that I have to change Sprocket’s `//= require` statements in application.js.rb to Ruby's ---------------------------------------------------------------------------------------------------- [17:58:44] Can Edremitoglu(@cantonic):@elia ok. let me revert the changes to application.js.rb and try your suggestion to make sure ---------------------------------------------------------------------------------------------------- [17:59:27] Elia Schito(@elia):please paste the broken code so that I know how to fix it in case someone else gets the error ---------------------------------------------------------------------------------------------------- [18:00:35] Can Edremitoglu(@cantonic):@elia the broken code is a simple `alert “foo”` ---------------------------------------------------------------------------------------------------- [18:01:12] Can Edremitoglu(@cantonic):I know changed my application.js.rb back to application.js and used Sprocket’s require statements: broken ---------------------------------------------------------------------------------------------------- [18:01:25] Can Edremitoglu(@cantonic):I will create a github issue explaining it further if you want ---------------------------------------------------------------------------------------------------- [18:01:37] Adam Beynon(@adambeynon):@cantonic If you comment out that line, does it then work? ---------------------------------------------------------------------------------------------------- [18:02:02] Adam Beynon(@adambeynon):do you define alert() ? ---------------------------------------------------------------------------------------------------- [18:02:12] Adam Beynon(@adambeynon):(might be a Native issue, for example) ---------------------------------------------------------------------------------------------------- [18:02:29] Can Edremitoglu(@cantonic):@adambeynon when commenting it out the error is gone, but the same errors happens for any kind of code. ---------------------------------------------------------------------------------------------------- [18:02:49] Can Edremitoglu(@cantonic):I also get a `WARNING: LoadError: cannot load such file -- application` from `runtime.js` ---------------------------------------------------------------------------------------------------- [18:04:22] Can Edremitoglu(@cantonic):now i am renaming application.js to application.js.rb ---------------------------------------------------------------------------------------------------- [18:04:29] Can Edremitoglu(@cantonic):one sec ---------------------------------------------------------------------------------------------------- [18:04:38] Adam Beynon(@adambeynon):@cantonic are you running pow? or anything similar?

Instead we have an additional javasceript_include_tag for it ---------------------------------------------------------------------------------------------------- [15:13:03] Elia Schito(@elia):@cantonic and the error comes from which include tag? ---------------------------------------------------------------------------------------------------- [15:13:53] Can Edremitoglu(@cantonic):from the controller specific one in this case ---------------------------------------------------------------------------------------------------- [15:13:59] Can Edremitoglu(@cantonic):but the files are working fine ---------------------------------------------------------------------------------------------------- [15:14:07] Can Edremitoglu(@cantonic):I just get the warning message i posted above ---------------------------------------------------------------------------------------------------- [15:14:19] Can Edremitoglu(@cantonic):it says it cannot load the file but it can ---------------------------------------------------------------------------------------------------- [15:14:45] Can Edremitoglu(@cantonic):@elia Do you want me to set up a rails application and push it on github in order to help you to reproduce it? ---------------------------------------------------------------------------------------------------- [15:15:11] Elia Schito(@elia):would be much easier that way ---------------------------------------------------------------------------------------------------- [15:15:16] Elia Schito(@elia):@cantonic thanks ---------------------------------------------------------------------------------------------------- [15:21:12] Can Edremitoglu(@cantonic):alright ---------------------------------------------------------------------------------------------------- [17:06:43] Can Edremitoglu(@cantonic):@elia https://github.com/cantonic/opal_demo ---------------------------------------------------------------------------------------------------- [17:06:59] Can Edremitoglu(@cantonic):i have created different branches for testing different combinations. see the README ---------------------------------------------------------------------------------------------------- [17:07:52] Can Edremitoglu(@cantonic):especially variant5 is interesting for you i guess ---------------------------------------------------------------------------------------------------- [17:10:22] Elia Schito(@elia):@cantonic thanks will have a look as soon as I can ---------------------------------------------------------------------------------------------------- [23:19:08] Elia Schito(@elia):@cantonic (checked master so far) the problem is the following: if you use application as a manifest (i.e. plain js with a list of requires) you are responsible for loading opal code ---------------------------------------------------------------------------------------------------- [23:19:39] Elia Schito(@elia):with `Opal.load('opal'); Opal.load('home_view')` ---------------------------------------------------------------------------------------------------- [23:24:20] Elia Schito(@elia):@cantonic variant1 should be fixed on master (`AssetFilteredError`) ---------------------------------------------------------------------------------------------------- ############################## [2015-03-26] ############################## [11:35:18] Kurtis Rainbolt-Greene(@krainboltgreene):@elia: It seems like a lot of the opal projects have pretty weird dependencies. ---------------------------------------------------------------------------------------------------- [11:35:39] Elia Schito(@elia):what do you mean? ---------------------------------------------------------------------------------------------------- [11:36:05] Elia Schito(@elia):@krainboltgreene ^ ---------------------------------------------------------------------------------------------------- [11:45:48] Kurtis Rainbolt-Greene(@krainboltgreene):Like, why does opal/opal need tilt? ---------------------------------------------------------------------------------------------------- [11:46:33] Adam Beynon(@adambeynon):@krainboltgreene I think Sprockets depends on it ---------------------------------------------------------------------------------------------------- [11:46:56] Adam Beynon(@adambeynon):and Opal uses sprockets for easier building with rails/sinatra/other-rack-framework ---------------------------------------------------------------------------------------------------- [11:47:37] Kurtis Rainbolt-Greene(@krainboltgreene):It's specified as an explicit dependency in opal, but yes sprockets does apparently explicitly require tilt. Weird. ---------------------------------------------------------------------------------------------------- [11:48:54] Kurtis Rainbolt-Greene(@krainboltgreene):And opal/opal-browser has paggio as an explicit dependency. ---------------------------------------------------------------------------------------------------- [11:50:07] Adam Beynon(@adambeynon):That I do find strange. Pagio relies on opal-browser, but Im not sure why the dependencies are that way around ---------------------------------------------------------------------------------------------------- [11:51:26] Kurtis Rainbolt-Greene(@krainboltgreene):It also looks like I was seeing a "lot" of weird dependencies because of middleman. Somehow my eyes missed the divide. ---------------------------------------------------------------------------------------------------- [11:56:49] Kurtis Rainbolt-Greene(@krainboltgreene):What's you all's prefered way to handle stand alone opal apps? I tried jekyll, with a pure opal thing, and now attempting middleman for this vienna. ---------------------------------------------------------------------------------------------------- [11:58:19] Elia Schito(@elia):@krainboltgreene @adambeynon tilt is there because it's going to be removed from deps in sprockets 3, the same goes with hike ---------------------------------------------------------------------------------------------------- [11:59:00] Elia Schito(@elia):that's the reason for keeping them explicit, because we're using them directly and don't want to break when sprockets 3 will be out (soon) ---------------------------------------------------------------------------------------------------- [11:59:03] Kurtis Rainbolt-Greene(@krainboltgreene):Ahhh. ---------------------------------------------------------------------------------------------------- [12:22:24] Kurtis Rainbolt-Greene(@krainboltgreene):Bleh, gave up middleman. Stasis uses an old version of tilt. Nanoc uses a directory called "lib". ---------------------------------------------------------------------------------------------------- [12:34:33] Adam Beynon(@adambeynon):@krainboltgreene We use middleman + opal for the website, opalrb.org ---------------------------------------------------------------------------------------------------- [12:34:46] Adam Beynon(@adambeynon):I think they have a sprockets plugin which we just tag onto ---------------------------------------------------------------------------------------------------- [16:38:11] Elia Schito(@elia):@adambeynon so you haven't been interviewed at bath ruby… :D https://www.youtube.com/watch?v=Em49QAJF-7Q ---------------------------------------------------------------------------------------------------- [18:03:57] George Plymale II(@ylluminarious):hey everyone, i was using 0.7.1 on a project of mine and it looks like something went wrong with loading some files. i was attempting to load files in the following way (which was working fine when i used 0.6.3): ``` require './file1' require './file2' require './file3' ``` i got an error that said: `Error: Opal::Builder::MissingRequire: A file required by "main" wasn't found.` and then it had a bunch of other information after it that said where it was getting messed up in requiring the files. i scratched my head for a bit after i saw this and then i decided to switch back to 0.6.3 and the error disappeared. i figured i should let you folks know about this in case someone accidentally broke something in 0.7.1 ---------------------------------------------------------------------------------------------------- [19:48:13] Kurtis Rainbolt-Greene(@krainboltgreene):@elia So with the availability of opal-react and my copy of React.js Native, I guess I can do ruby development on iPhone ;) ---------------------------------------------------------------------------------------------------- [19:49:08] Elia Schito(@elia)::+1: ---------------------------------------------------------------------------------------------------- [21:12:10] George Plymale II(@ylluminarious):@elia concerning that problem that i reported above earlier: https://github.com/opal/opal/issues/778 ---------------------------------------------------------------------------------------------------- ############################## [2015-03-27] ############################## [15:48:49] Elia Schito(@elia):otherwise we could try to detect if they're used in the view ---------------------------------------------------------------------------------------------------- [15:49:02] Elia Schito(@elia):hackish but probably do-able ---------------------------------------------------------------------------------------------------- [15:49:33] Elia Schito(@elia):last option–which i don't like– would be to make it a config flag ---------------------------------------------------------------------------------------------------- [15:57:45] Can Edremitoglu(@cantonic):@elia I like the first solution. saves resources, even though one could expect view templates to have access to ivars since they are also available in html or js.erb template views. ---------------------------------------------------------------------------------------------------- [15:57:59] Can Edremitoglu(@cantonic):@elia hey, what about .js.opal.erb? :D ---------------------------------------------------------------------------------------------------- [15:58:34] Elia Schito(@elia):> .js.opal.erb what do you mean? ---------------------------------------------------------------------------------------------------- [15:59:36] Elia Schito(@elia):for the first solution the only problem would be detecting locals, but probably if locals are set we can trust it's done intentionally ---------------------------------------------------------------------------------------------------- [16:00:25] Elia Schito(@elia):@cantonic can you open an issue on opal-rails as a reminder for this change? feel free to copy/paste the whole transcript :) ---------------------------------------------------------------------------------------------------- [16:01:32] Can Edremitoglu(@cantonic):@elia js.opal.erb was meant as a joke so you could do `Element[“#file_<%= @file.id %>”]` for example :) ---------------------------------------------------------------------------------------------------- [16:03:08] Can Edremitoglu(@cantonic):actually that wouldn’t be too bad… we wouldn’t have to compile the whole instance variable and one could use erb to get values from an instance variable into the code before it gets compiled. Additionally to this you could pass local variables to the template like usual and described in https://github.com/opal/opal-rails#as-a-template ---------------------------------------------------------------------------------------------------- [16:03:09] Elia Schito(@elia):@cantonic lol, yeah, would make sense if it wasn't so meta… `` ---------------------------------------------------------------------------------------------------- [16:03:24] Can Edremitoglu(@cantonic):hehehe ---------------------------------------------------------------------------------------------------- [16:06:28] Can Edremitoglu(@cantonic):i would say: if you need an instance variable or parts of it you should pass it in like `render type: :js, locals: {post: @post}` ---------------------------------------------------------------------------------------------------- [16:06:38] Can Edremitoglu(@cantonic):will create an issue for it ---------------------------------------------------------------------------------------------------- [16:09:29] Elia Schito(@elia):I think `locals:` should still produce locals in the view, but skipping unwanted ivars makes sense, even if it would break crazy code such as `class << self; attr_accessor :foo; end; p foo` ---------------------------------------------------------------------------------------------------- [16:09:40] Elia Schito(@elia):@adambeynon any thoughts on this? ---------------------------------------------------------------------------------------------------- [16:27:23] Adam Beynon(@adambeynon):@elia, @cantonic I like the opt-in approach using `locals: …` ---------------------------------------------------------------------------------------------------- [16:28:57] Can Edremitoglu(@cantonic):@elia, @adambeynon in that case it is as easy as removing https://github.com/opal/opal-rails/blob/master/lib/opal/rails/template_handler.rb#L24-L28 right? ---------------------------------------------------------------------------------------------------- [16:32:59] Elia Schito(@elia):@cantonic :+1: yes and update line 13, wanna do a PR for that? ---------------------------------------------------------------------------------------------------- [16:33:42] Can Edremitoglu(@cantonic):yep. i’ll take care of it right now ---------------------------------------------------------------------------------------------------- [16:37:33] Can Edremitoglu(@cantonic):just want to do one or two tests before to make sure the ivars are really breaking it ---------------------------------------------------------------------------------------------------- [16:48:22] Can Edremitoglu(@cantonic):wow, when trying to debug the template handler my editor crashes… must have to do with the “stack level too deep” error which somehow leaves the question if there is just a logical mistake in the handler... ---------------------------------------------------------------------------------------------------- [16:50:23] Can Edremitoglu(@cantonic):``` SystemStackError - stack level too deep: activesupport (4.1.9) lib/active_support/core_ext/object/json.rb:159:in `block in as_json' activesupport (4.1.9) lib/active_support/core_ext/object/json.rb:159:in `each' activesupport (4.1.9) lib/active_support/core_ext/object/json.rb:159:in `map' activesupport (4.1.9) lib/active_support/core_ext/object/json.rb:159:in `as_json' activesupport (4.1.9) lib/active_support/core_ext/object/json.rb:50:in `as_json' activesupport (4.1.9) lib/active_support/core_ext/object/json.rb:159:in `block in as_json' activesupport (4.1.9) lib/active_support/core_ext/object/json.rb:159:in `each' activesupport (4.1.9) lib/active_support/core_ext/object/json.rb:159:in `map' activesupport (4.1.9) lib/active_support/core_ext/object/json.rb:159:in `as_json' activesupport (4.1.9) lib/active_support/core_ext/object/json.rb:50:in `as_json’ … and so on ``` ---------------------------------------------------------------------------------------------------- [16:59:18] Elia Schito(@elia):seems there's just a loop in as_json, you can check lib/active_support/core_ext/object/json.rb at the stacktrace lines to see which class is that `as_json` from ---------------------------------------------------------------------------------------------------- [17:05:57] Can Edremitoglu(@cantonic):@elia does this have to do with it? https://github.com/rspec/rspec-rails/issues/1309 ---------------------------------------------------------------------------------------------------- [17:06:41] Can Edremitoglu(@cantonic):excerpt from https://github.com/rspec/rspec-rails/commit/9f6f9bda183b86bf50dcc7a657fb1757e19bf7bd : Rails adds a nearly global monkey patch to make converting objects into JSON easier. It adds both `to_json` and `as_json` methods on nearly all core object types; including `Object` but not `BasicObject`. ---------------------------------------------------------------------------------------------------- [17:08:35] Elia Schito(@elia):yep, tldr, but given it's recursive that's probably the culprit ---------------------------------------------------------------------------------------------------- [17:10:51] Can Edremitoglu(@cantonic):okay. maybe I can solve it with a little help of you from time to time :) ---------------------------------------------------------------------------------------------------- [17:11:40] Elia Schito(@elia):sure thing ---------------------------------------------------------------------------------------------------- [17:13:39] Elia Schito(@elia):> make sure the ivars are really breaking it forgot to mention that the problem is not ivars per se but the `to_json` transformation, going from ivars to locals (which is good anyway) won't help as locals are still treated with `to_json` ---------------------------------------------------------------------------------------------------- [17:15:14] Can Edremitoglu(@cantonic):@elia so `render type: :js, locals: {directory: @directory}` should produce the same error, right? ---------------------------------------------------------------------------------------------------- [17:16:20] Elia Schito(@elia):I think so ---------------------------------------------------------------------------------------------------- [17:17:29] Can Edremitoglu(@cantonic):yeah it does ---------------------------------------------------------------------------------------------------- [17:21:18] Can Edremitoglu(@cantonic):in that case removing `Opal::Rails::TemplateHandler#assigns` wouldn’t solve the problem since people would run into that problem pretty quickly. ---------------------------------------------------------------------------------------------------- [18:07:26] Elia Schito(@elia):@cantonic properly implementing to_json would solve, helping understand that to_json will be called on all ivars/locals is another option, but I don't know how we could do that ---------------------------------------------------------------------------------------------------- [18:08:38] Can Edremitoglu(@cantonic):me neither :( ---------------------------------------------------------------------------------------------------- [19:19:30] Can Edremitoglu(@cantonic):ok, the error happens for `@_assigns`, not for `local_assigns`. the latter can call `to_json` without problem. I am removing the `assigns` method like we discussed earlier ---------------------------------------------------------------------------------------------------- [19:47:17] Elia Schito(@elia):K, was hacky (but cool) from the beginning ---------------------------------------------------------------------------------------------------- [20:29:12] Elia Schito(@elia):@cantonic looking again at the code, seems odd that there's no difference between using ivars and locals, just saying… ---------------------------------------------------------------------------------------------------- [20:29:58] Can Edremitoglu(@cantonic):@elia well the locals are simple and not as deeply nested as ‘@_assigns' ---------------------------------------------------------------------------------------------------- [20:31:21] Can Edremitoglu(@cantonic):but removing the ivars and going with locals is also not optimal. i passed in an activerecord object as a local, but in the template file it is just a json string. You cannot use its methods which you can with erb ---------------------------------------------------------------------------------------------------- [20:31:47] Elia Schito(@elia):it's a different beast ---------------------------------------------------------------------------------------------------- [20:32:29] Elia Schito(@elia):The idea is that youre passing (controlled) attributes to opal and there possibly use them to instantiate a clientside model ---------------------------------------------------------------------------------------------------- [20:33:21] Elia Schito(@elia):you can wrap them in OpenStruct or Struct ---------------------------------------------------------------------------------------------------- [20:34:00] Elia Schito(@elia):you can also pass the values you need as locals/ivars calling the methods (aka preparing the data) in the controller ---------------------------------------------------------------------------------------------------- [20:37:21] Can Edremitoglu(@cantonic):yep right. you can get done what you need to get done but in a more inconvenient way as with coffee+erb templates. somehow at some time it would be good to be able to be able to use the locals and ivars like you can with erb I think. ---------------------------------------------------------------------------------------------------- [20:38:18] Can Edremitoglu(@cantonic):@elia using OpenStruct? like `render locals: {post: OpenStruct.new(@post)` ? ---------------------------------------------------------------------------------------------------- [20:38:26] Elia Schito(@elia):I'm ok with that as long as the solution is not super confusing, the problem is that you're mixing server and clientside stuff ---------------------------------------------------------------------------------------------------- [20:39:33] Elia Schito(@elia):it's a problem of serialization/deserialization; would be serialized in MRI and deserialized in Opal ---------------------------------------------------------------------------------------------------- [20:40:10] Elia Schito(@elia):the safest thing I came up was hash/array/…->json->hash/array/… ---------------------------------------------------------------------------------------------------- [20:40:50] Elia Schito(@elia):as all the types used by json are guaranteed to be available on the client, ---------------------------------------------------------------------------------------------------- [20:41:11] Elia Schito(@elia):not sure how it could play out with OpenStruct ---------------------------------------------------------------------------------------------------- [20:41:13] Can Edremitoglu(@cantonic):therefore I thought about bringing erb into the game so you can use both: locals for client side stuff and erb for server side ---------------------------------------------------------------------------------------------------- [20:42:25] Can Edremitoglu(@cantonic):you could prepare your locals in the controller but also quickly do a `<% if @post.new_record? %>` if you quickly need it ---------------------------------------------------------------------------------------------------- [20:42:28] Elia Schito(@elia):if you want to take a knack at implementing that :+1:, after all anyone adding `.opal.erb` as an extension is supposed to know what he's doing ---------------------------------------------------------------------------------------------------- [20:43:36] Elia Schito(@elia):I'll help of course, even if I'm not completely aware of how chaining multiple templates works in app/views ---------------------------------------------------------------------------------------------------- [01:31:27] Can Edremitoglu(@cantonic):@elia thx for the answer ---------------------------------------------------------------------------------------------------- [01:35:24] Can Edremitoglu(@cantonic):what do you guys think of extending opal-jquery’s `Element#expose` so one can define a custom alias name so you can do `Element.expose :fullCalendar, :full_calendar` in order to avoid having camel case ruby method for example ? ---------------------------------------------------------------------------------------------------- [02:26:34] Kurtis Rainbolt-Greene(@krainboltgreene):Looks like `Opal::Processor.source_map_register` has gone? ---------------------------------------------------------------------------------------------------- [02:26:40] Kurtis Rainbolt-Greene(@krainboltgreene):I don't see it in the changelog. ---------------------------------------------------------------------------------------------------- [02:35:44] Can Edremitoglu(@cantonic):@krainboltgreene it has been removed in #773 ---------------------------------------------------------------------------------------------------- [02:39:18] Kurtis Rainbolt-Greene(@krainboltgreene):Christ. Slap me if I ever have to write something that depends on Sprockets. ---------------------------------------------------------------------------------------------------- [03:42:50] Kurtis Rainbolt-Greene(@krainboltgreene):@elia: Seem to be having a odd compile situation: https://gist.github.com/krainboltgreene/f36eb99799336e00a43f ---------------------------------------------------------------------------------------------------- [03:45:32] Kurtis Rainbolt-Greene(@krainboltgreene):Didn't realize it would spam the channel, sorry. ---------------------------------------------------------------------------------------------------- [03:47:41] Kurtis Rainbolt-Greene(@krainboltgreene):Also realized it was a thing that I did wrong, not something with the compiler. It's really hard to adjust to this transpiler situation. Trying to figure out where the problem is really located, not because Opal is dumb about it but because I don't know the context it's reporting in. ---------------------------------------------------------------------------------------------------- [09:38:13] Can Edremitoglu(@cantonic):hmm… I cannot get rails to render a create.js.opal file. create.js works fine. Using the .js.opal extension leads to a 500 error without any further explanationation in development.log as well as no javascript console errors. ---------------------------------------------------------------------------------------------------- [09:38:43] David Chang(@zetachang):@krainboltgreene open up an issue here (https://github.com/zetachang/react.rb/issues/14) for supporting React Native in react.rb ---------------------------------------------------------------------------------------------------- [09:39:13] Kurtis Rainbolt-Greene(@krainboltgreene):@cantonic I believe the standard is create.js.rb? ---------------------------------------------------------------------------------------------------- [09:40:11] Kurtis Rainbolt-Greene(@krainboltgreene):@zetachang I just got started using react.rb, which is wonderfully done btw. ---------------------------------------------------------------------------------------------------- [09:40:41] David Chang(@zetachang):@krainboltgreene Glad to hear, thanks! :wink: ---------------------------------------------------------------------------------------------------- [09:44:10] Can Edremitoglu(@cantonic):@krainboltgreene I think it isn’t when using opal for server javascript responses. I get a “missing template” error when using js.rb and [this section of the opal-rails README](https://github.com/opal/opal-rails#as-a-template) also indicates to use js.opal ---------------------------------------------------------------------------------------------------- [09:45:26] Kurtis Rainbolt-Greene(@krainboltgreene):Hmm, thought I saw a comment recently about using `.js.rb`. ---------------------------------------------------------------------------------------------------- [09:45:28] Kurtis Rainbolt-Greene(@krainboltgreene):Interesting. ---------------------------------------------------------------------------------------------------- [09:46:04] Kurtis Rainbolt-Greene(@krainboltgreene):Either way, I bet there's a better way to debug the sprocket part of the request. ---------------------------------------------------------------------------------------------------- [09:46:34] Kurtis Rainbolt-Greene(@krainboltgreene):@cantonic: Try with ` <%= javascript_include_tag "application", :debug => true %>` ---------------------------------------------------------------------------------------------------- [09:46:50] Can Edremitoglu(@cantonic):@krainboltgreene yes, usually you use `.js.rb` for opal files in `app/assets/javascripts`, but it doesn’t work for js template files in `app/views` ---------------------------------------------------------------------------------------------------- [09:47:08] Can Edremitoglu(@cantonic):thx. will try that ---------------------------------------------------------------------------------------------------- [09:47:28] Kurtis Rainbolt-Greene(@krainboltgreene):Oh crap, sorry, somehow missed template views. ---------------------------------------------------------------------------------------------------- [09:47:54] Kurtis Rainbolt-Greene(@krainboltgreene):I've never been a fan of app/view/*.js files, so I'm no help. ---------------------------------------------------------------------------------------------------- [09:49:12] Can Edremitoglu(@cantonic):@krainboltgreene i just start becoming a fan of them. previously I used client side ajax calls and made json responses handled by the client, but using server js responses has a lot of advantages over the other approach for me. ---------------------------------------------------------------------------------------------------- [10:15:51] Can Edremitoglu(@cantonic):oh nice, somehow it is working now. Don’t know what caused the error unfortunately ---------------------------------------------------------------------------------------------------- [10:29:27] Can Edremitoglu(@cantonic):and back to error again… weird. is it possible that the latest Sprockets changes prevent files like `create.js.opal` from working? ---------------------------------------------------------------------------------------------------- [10:50:52] Can Edremitoglu(@cantonic):ok, after disabling forgery protection I at least get an error message: `stack level too deep` in `create.js.opal`. The method causing it is `alert 'foobar'` ---------------------------------------------------------------------------------------------------- [10:54:36] Can Edremitoglu(@cantonic):narrowed it down to the instance variables set in the controller’s #create action. They are causing a `stack level too deep` error. When I remove them in the #create action it is working fine. ---------------------------------------------------------------------------------------------------- [10:58:56] Adam Beynon(@adambeynon):@cantonic Im not sure of exactly how it works, as @elia did the templating stuff for rails ---------------------------------------------------------------------------------------------------- [10:58:59] Adam Beynon(@adambeynon):but, https://github.com/opal/opal-rails/blob/master/lib/opal/rails/template_handler.rb#L1-L35 ---------------------------------------------------------------------------------------------------- [10:59:30] Adam Beynon(@adambeynon):it looks like locals are handled via #to_json - so maybe there is something bad in one of the models getting converted to json - recursive objects maybe ---------------------------------------------------------------------------------------------------- [11:01:05] Can Edremitoglu(@cantonic):@adambeynon thank you. I assume the same. ---------------------------------------------------------------------------------------------------- [13:03:02] Elia Schito(@elia):@krainboltgreene `@router = Ghostryder::Router.new` does it work with `@router = ::Ghostryder::Router.new`? ---------------------------------------------------------------------------------------------------- [13:03:29] Elia Schito(@elia):if it works on MRI without the double colon please open an issue ---------------------------------------------------------------------------------------------------- [13:04:59] Elia Schito(@elia):@cantonic didn't use app/views templates in a while, can you try applying `to_json` to all ivars in the controller manually, if it breaks there that's the issue ---------------------------------------------------------------------------------------------------- [13:16:52] Can Edremitoglu(@cantonic):@elia: the controller handles it without any problems ---------------------------------------------------------------------------------------------------- [13:17:44] Elia Schito(@elia):@cantonic can you post some code?

Hope that helps for further investigation :) ---------------------------------------------------------------------------------------------------- [13:45:46] Elia Schito(@elia)::+1: ---------------------------------------------------------------------------------------------------- [15:42:48] Can Edremitoglu(@cantonic):@elia is the `stack level too deep` error happening because the template handler tries to transform the instance variables and all their methods etc into json? If so, could we change the template handler to perform to_json only on the instances attributes? or maybe even totally remove the instances from automatically being available and instead pass local variables to the js.opal file if necessary? ---------------------------------------------------------------------------------------------------- [15:48:27] Elia Schito(@elia):@cantonic simplest solution would be to set those vars only when needed by the view, but that's probably my hate for passing data via ivars that's talking here ---------------------------------------------------------------------------------------------------- ############################## [2015-03-28] ############################## [01:27:56] Kurtis Rainbolt-Greene(@krainboltgreene):I'm super interested in getting react.rb into a framework, maybe like Clearwater. ---------------------------------------------------------------------------------------------------- [01:28:53] Kurtis Rainbolt-Greene(@krainboltgreene):But I want something well defined and composed like ember and ember-cli. ---------------------------------------------------------------------------------------------------- [04:10:14] Kurtis Rainbolt-Greene(@krainboltgreene):@elia If I wanted to use rom-rb in an opal app, a gem that shouldn't have any non-standard API usage or c-extensions, how would I go about doing that? ---------------------------------------------------------------------------------------------------- [08:26:49] Elia Schito(@elia):In MRI you would Opal.use_gem "rom" and then require "Tom" in Opal ---------------------------------------------------------------------------------------------------- [18:36:16] Kurtis Rainbolt-Greene(@krainboltgreene):@elia: As cool as that is it looks like ROM has a dynamic require. Foiled. ---------------------------------------------------------------------------------------------------- [23:46:12] Elia Schito(@elia):@krainboltgreene if you explicitly require the files that would be required by the dynamic require it should work fine (remember to set the dynamic require error level to warning or ignore) ---------------------------------------------------------------------------------------------------- [23:48:46] Kurtis Rainbolt-Greene(@krainboltgreene):@elia: Quite frankly I don't think dynamic requires are really that good an idea anyways. I'm hoping to patch it out. ---------------------------------------------------------------------------------------------------- [23:48:49] Kurtis Rainbolt-Greene(@krainboltgreene):But thanks for the detail. ---------------------------------------------------------------------------------------------------- [23:52:31] Elia Schito(@elia):Most of them are not really dynamic anyway ---------------------------------------------------------------------------------------------------- ############################## [2015-03-30] ############################## [17:34:04] Vitor Capela(@dodecaphonic):When writing a bridge to a library, is it customary/recommended for it to be prefixed by "opal-"? ---------------------------------------------------------------------------------------------------- [18:01:57] Kurtis Rainbolt-Greene(@krainboltgreene):Good question. ---------------------------------------------------------------------------------------------------- [18:02:17] Kurtis Rainbolt-Greene(@krainboltgreene):Some of the opal org libraries follow this structure ---------------------------------------------------------------------------------------------------- [18:02:26] Kurtis Rainbolt-Greene(@krainboltgreene):But things like vienna, clearwater, react.rb don't. ---------------------------------------------------------------------------------------------------- [18:03:08] Kurtis Rainbolt-Greene(@krainboltgreene):@dodecaphonic: I think it's a good idea for the gem to have opal-* (for better indexing), but the vendor library to not have it. ---------------------------------------------------------------------------------------------------- [18:03:19] Kurtis Rainbolt-Greene(@krainboltgreene):AKA gem "opal-foo", require "foo" ---------------------------------------------------------------------------------------------------- [18:16:00] Vitor Capela(@dodecaphonic):Great.

I'm briding their responses wrapped in Natives, but I was wondering if it would be better to convert them to Hashes. Is there a consensus on what to do? Is there a standard way to perform that conversion? ---------------------------------------------------------------------------------------------------- [19:20:16] Vitor Capela(@dodecaphonic):A user can store documents with different shapes, so I'm not quite sure how to proceed. ---------------------------------------------------------------------------------------------------- [20:30:10] Mitch VanDuyn(@catmando):@elia (or anybody else, that knows) we are using opal-rspec, and /opal_spec is visible in our production app... is there a simple way to turn this off, that we just missed in the docs? (I had been sending this by mistake over in the volt room, sorry about that!) ---------------------------------------------------------------------------------------------------- [21:07:13] Forrest Chang(@fkchang):@dodecaphonic if you don't return hashes, document. I think the principle of least surprise would dictate that when coding in opal, objects are opal objects (i.e. we just code in Ruby), as being more comfortable and requiring less divergent thought, .i.e. "oh yeah, what this returns isn't really a Hash, so I can only use these 2 operators". ---------------------------------------------------------------------------------------------------- [21:08:04] Vitor Capela(@dodecaphonic):@fkchang That's what I think as well, for sure. That said, is there a helper to go from nested js.Object to a Hash already in place? ---------------------------------------------------------------------------------------------------- [21:08:31] Forrest Chang(@fkchang):@catmando /opal_spec is implemented as a rails engine, at the moment, I don't believe you can turn it off. That being said, I'm going to be doing some work on opal-rails and running specs, I could probably make it so it doesn't respond on production if you set some config value while I'm in there ---------------------------------------------------------------------------------------------------- [21:11:16] Adam Beynon(@adambeynon):@catmando @fkchang It used to be the case where the specs did not run in production.

I can give you remote access to a working example if you like ---------------------------------------------------------------------------------------------------- [17:12:00] Ryan Stout(@ryanstout):@adambeynon @elia how are you? I've been thinking about trying to add an extension to opal to support async/await similar to how es7 does. (Basically, await is a keyword that gets passed a promise, then all code below it in the AST is put inside of the promise. And async just wraps the results of a method in a promise) async/await basically lets you write code that looks synchronous. And I was thinking, it would be easy enough to create a similar library on the server that uses fibers to accomplish the same interface. Any thoughts on the best way for me to get started? I think I could implement async as a method that takes in the symbol returned from ```def``` and then wraps that method. But for await, it would have to become a language keyword. I can figure out how to do the AST transforms, I'm just not sure the best way to extend opal so it won't need many changes when opal changes. Any thoughts? ---------------------------------------------------------------------------------------------------- [20:31:29] Forrest Chang(@fkchang):@adambeynon @elia anything for updating to 0.8.0.dev stuff in head?

Sign me up :-) ---------------------------------------------------------------------------------------------------- [06:31:50] Forrest Chang(@fkchang):@jaredcwhite I'm up for that, I'd be happy to contribute as I am able to find time. There's been tons of good stuff on irc, though that seems to have died down now that gitter is getting done adoption. One thing for the newsletter could just be good nuggets from irc or gitter since the last newsletter ---------------------------------------------------------------------------------------------------- [06:42:55] Kurtis Rainbolt-Greene(@krainboltgreene):Same. ---------------------------------------------------------------------------------------------------- [08:06:38] Elia Schito(@elia):me too ---------------------------------------------------------------------------------------------------- [12:29:17] David Chang(@zetachang):Hey all, days ago mentioning that I am doing some rewrite to make react.rb support toll-free bridge ReactComponent. I got some code up and running (with some help from inline doc in `runtime.js`). https://gist.github.com/zetachang/abf76b110ac5c80bd4e9 ---------------------------------------------------------------------------------------------------- [12:32:29] Kurtis Rainbolt-Greene(@krainboltgreene):Swweeeet. ---------------------------------------------------------------------------------------------------- [12:32:38] David Chang(@zetachang):I have to override the constructor property since React.js rely on this to check if the component instance are the one instantiated from the element. So the questions is that is this the right way to do this? Since this depends on the usage of `klass._proto` which is actually an implementation details ---------------------------------------------------------------------------------------------------- [13:11:13] David Chang(@zetachang):@jaredcwhite count me in :+1: ---------------------------------------------------------------------------------------------------- [14:07:28] Jared White(@jaredcwhite):All right! Appreciate everyone's enthusiasm. :) I'll work on the first issue next week. ---------------------------------------------------------------------------------------------------- [14:47:26] Elia Schito(@elia):@zetachang have you tried bridging the class? class React::Component < `React.Component` ---------------------------------------------------------------------------------------------------- [14:49:16] David Chang(@zetachang):Yes, i've tried. But since React need a constructor function. So I need to manually set up the prototype chain. ---------------------------------------------------------------------------------------------------- [14:55:16] Elia Schito(@elia):I probably need to study React constructor a bit more to understand the code above, but as a heads up I can say that _proto becomes $$proto from 0.7 on ---------------------------------------------------------------------------------------------------- [14:57:58] David Chang(@zetachang):Actually the reason why I choose copy React.Component.prototype is to remain the previous behavior that any plain Ruby class could be a renderable component class. ---------------------------------------------------------------------------------------------------- [14:58:43] David Chang(@zetachang):Noted on the $$proto part, I will migrate to it after 0.8 released. ---------------------------------------------------------------------------------------------------- ############################## [2015-04-05] ############################## [12:53:46] David Chang(@zetachang):Hey all, just got Opal Ruby up & running in React Native (https://github.com/zetachang/opal-native) ---------------------------------------------------------------------------------------------------- [12:54:54] David Chang(@zetachang):Toolchain implemented in pure Ruby, currently it's kind of a proof of concept.

When querying, you can pass a function in or specify a "design document" -- a permanent way to go through data. On the latter, you pass in a stringified function (the guides tell you to call toString() on a function), which means it passes the raw code in and forgoes closures and such things. ---------------------------------------------------------------------------------------------------- [18:27:55] Vitor Capela(@dodecaphonic):Is there a way to get a transformed lambda as a string without the closures? Do you have any ideas how to make that look a little better? ---------------------------------------------------------------------------------------------------- ############################## [2015-04-07] ############################## [02:21:57] Can Edremitoglu(@cantonic):is it possible that since the latest changes to opal-rails it is necessary to name haml templates `js.haml` instead of just `haml`? with just `haml` as filename I get a `Sprockets::FileNotFound` from the file that is requiring the haml template. It’s no problem for me to rename template files to `js.haml`, but that would break the concept of shared remplates in `app/views` like described in the opal-rails readme ---------------------------------------------------------------------------------------------------- [07:14:24] Elia Schito(@elia):@cantonic I'll add a spe for that and fix it, do you mind opening an issue as a reminder? ---------------------------------------------------------------------------------------------------- [07:20:08] Can Edremitoglu(@cantonic):@elia sure. In opal-rails repo? ---------------------------------------------------------------------------------------------------- [07:40:31] Elia Schito(@elia):i'd say opal-haml, but it's the same really ---------------------------------------------------------------------------------------------------- [09:56:40] Can Edremitoglu(@cantonic):alright, done: https://github.com/opal/opal-haml/issues/5 ---------------------------------------------------------------------------------------------------- [10:00:13] Elia Schito(@elia):let me know if the fix works, otherwise we'll reopen the issue ---------------------------------------------------------------------------------------------------- [10:09:20] Can Edremitoglu(@cantonic):yep, fixed it. thank you :) ---------------------------------------------------------------------------------------------------- [10:10:03] Elia Schito(@elia):@zetachang @krainboltgreene https://github.com/ssorallen/turbo-react/ no more original ideas… ---------------------------------------------------------------------------------------------------- [17:25:04] Jared White(@jaredcwhite):@zetachang @fkchang @ryanstout @krainboltgreene @elia @adambeynon OK, for the Opal newsletter, I'm still working on a website but I have the email sign-up ready to go. It's called Opalist. :) https://opalist.curated.co Hoping to get an issue out in a week or so. ---------------------------------------------------------------------------------------------------- [17:29:17] Ryan Stout(@ryanstout):@jaredcwhite awesome, looking forward to it :-) ---------------------------------------------------------------------------------------------------- [18:39:23] Forrest Chang(@fkchang):@jaredcwhite cool. Hope to have some material for you, just posted a blog post of ruby-fying javascript - would like to make a series out of it ---------------------------------------------------------------------------------------------------- ############################## [2015-04-08] ############################## [00:09:26] Cassio Godinho(@cpgo):Any thing new about rubyfire? ---------------------------------------------------------------------------------------------------- [11:35:51] Fred Mitchell(@flajann2):Should I even bother with Angular with Opal? I am thinking I should be able to accomplish the same functionality totally within Opal. Same question for D3. Thoughts? ---------------------------------------------------------------------------------------------------- [20:37:06] Jared White(@jaredcwhite):@flajann2 Well Opal in and of itself won't provide most of the framework-y things that Angular will provide for you. You'll need extra libraries. You could check out Vienna, or React.rb, or Clearwater, or some other things along those lines. We're all waiting for Rubyfire as well. :) Myself, I ended up creating a Backbone-ish framework for controller/view modularization on a big client project, and at some point I might extract it out into a gem but it's not quite ready for prime-time just yet. ---------------------------------------------------------------------------------------------------- [20:46:30] Forrest Chang(@fkchang):@flajann2 Depends on what it is you need/want to do. More often than not I find myself not needed libraries. The only one I've used in depth w/Opal is Lissio, which most ppl seem to not grok, but with React getting popular, more people might. D3 on the other hand, I'd just wrap ( I think someone took a stab at it already, maybe it was a blog post I read) coz it's too much effort to redo in Opal, and performance is an issue. ---------------------------------------------------------------------------------------------------- [20:48:31] Forrest Chang(@fkchang):Just having real classes, sane scoping, and high level language makes a lot of JS libs/frameworks unecessary ---------------------------------------------------------------------------------------------------- ############################## [2015-04-09] ############################## [14:21:47] Elia Schito(@elia):'t was lol :D ---------------------------------------------------------------------------------------------------- [14:40:11] Juan Francisco Giménez Silva(@juanfgs):got it working! :) ---------------------------------------------------------------------------------------------------- [14:42:42] Juan Francisco Giménez Silva(@juanfgs):I created this Rakefile http://pastebin.com/epbarJqD just in case some one is struggling with that issue ---------------------------------------------------------------------------------------------------- [14:42:43] Juan Francisco Giménez Silva(@juanfgs): still don't know why it doesn't work with just gem install and ruby -r opal-browser, but this seems to work ---------------------------------------------------------------------------------------------------- [14:51:38] Elia Schito(@elia)::+1: ---------------------------------------------------------------------------------------------------- [16:01:21] Forrest Chang(@fkchang):@adambeynon @elia seems like the react.rb dsl is very close to @meh 's paggio, maybe that could be the common template format for rails and react.rb ---------------------------------------------------------------------------------------------------- [04:41:51] Fred Mitchell(@flajann2):Thanks @fkchang and @jaredcwhite for your inputs. I am creating a control panel for my neural network engine RubyNEAT, and eventually want it to be a full-blown dev environment where you can monitor the evolution and make changes to some of the parameters, tweaking them in real time. So it will be heavy on the visualization. I find D3 annoying to work with directly, but like its performance. Angular 2 is coming out soon as well, but would just rather (re)do everything in Opal. Using Sinatra as a light-weight interface to RubyNEAT as a plugin, but I don't like some of the issues I am having with it, as Sinatra wants to "steal" the entire show... ---------------------------------------------------------------------------------------------------- [04:47:03] Fred Mitchell(@flajann2):Lisso is looking pretty good.

I'm trying to make it so I can run more of Volt in with opal-rspec. The big problem I'm running into is with jquery. Basically I would like to just not load jquery in the specs since I can stub the dom stuff that gets used. The problem is in one part of Volt, I do: ```ruby if RUBY_PLATFORM == 'opal' require 'opal-jquery' end ``` Is there any way to make it not require opal-jquery when running in the specs?

I was hoping to write a few blogs about the structure of a large opal app I have (about 1.8mb of minimized javascript - very large!). its a very mature app, so I think a lot of the structure could be useful for other people thinking about large opal apps - handling routes, controllers, caching json etc ---------------------------------------------------------------------------------------------------- [18:36:11] Bráulio Bhavamitra(@brauliobo):hello all, sorry for asking such a question, but anyone ever thought of a ruby vm based on opal? ---------------------------------------------------------------------------------------------------- [18:39:15] Adam Beynon(@adambeynon):@brauliobo opal (more specifically javascript) makes it difficult to support everything in ruby ---------------------------------------------------------------------------------------------------- [18:39:21] Adam Beynon(@adambeynon):a big problem would be Threads ---------------------------------------------------------------------------------------------------- [18:39:32] Adam Beynon(@adambeynon):so there are some things which we could never support ---------------------------------------------------------------------------------------------------- [18:40:34] Bráulio Bhavamitra(@brauliobo):@adambeynon threads is not supported by webworkers or something on node.js? ---------------------------------------------------------------------------------------------------- [18:40:48] Bráulio Bhavamitra(@brauliobo):what more would be difficult? ---------------------------------------------------------------------------------------------------- [18:41:56] Bráulio Bhavamitra(@brauliobo):https://github.com/audreyt/node-webworker-threads ---------------------------------------------------------------------------------------------------- [18:42:04] Bráulio Bhavamitra(@brauliobo):webworkers on node.js ---------------------------------------------------------------------------------------------------- [18:51:06] Forrest Chang(@fkchang):@jaredcwhite nice work -- ur giving me incentive to provide content for it ---------------------------------------------------------------------------------------------------- [18:52:27] Ryan Stout(@ryanstout):@adambeynon if you have a second, any ideas on the cause of this? https://github.com/opal/opal/issues/500 (I keep running into this one, and I might take a shot at fixing it for 0.8 if you can point me in the right direction) ---------------------------------------------------------------------------------------------------- [18:55:58] Jared White(@jaredcwhite):@fkchang Awesome! That's the idea :) @adambeynon That sounds great, I'd love to read about that. ---------------------------------------------------------------------------------------------------- [19:04:56] Ryan Stout(@ryanstout):@jaredcwhite great job on the first opalist :-) ---------------------------------------------------------------------------------------------------- [19:05:41] Ryan Stout(@ryanstout):@adambeynon one other question, maybe there's an issue for it. But the default inspect in irb shows instance variables, would you take a PR for that? ---------------------------------------------------------------------------------------------------- ############################## [2015-04-15] ############################## [13:50:26] Vais Salikhov(@vais):@jaredcwhite The pleasure's all mine, thank you, Jared! ---------------------------------------------------------------------------------------------------- [13:54:54] Vais Salikhov(@vais):@jaredcwhite BTW your "But your kids are gonna love it..." post has been in the number one spot on http://www.reddit.com/r/ruby all day today.

I assume the problem comes from the upgrade to Sprockets 3. ---------------------------------------------------------------------------------------------------- [20:06:38] Forrest Chang(@fkchang):@ryanstout @adambeynon ironically I tackled the inspect thing for the same reason. I had to use a method I have in opal-irb that gives me just the "ruby instance variables" i.e. there are asserted instance variables that are not normal to ruby, i.e. for 0.7.1 there is @constructor and @toString, so I filter those out. I gave a coworker a monkey patch to run in his opal-irb ---------------------------------------------------------------------------------------------------- ############################## [2015-04-16] ############################## [05:31:08] Ryan Stout(@ryanstout):@adambeynon or @elia have either of you ran into this issue?

Its a blocker for me :-) ---------------------------------------------------------------------------------------------------- [05:41:39] Ryan Stout(@ryanstout):ok, tracked down the issue. Basically ```true.hash``` doesn't return a consistent value. ---------------------------------------------------------------------------------------------------- [05:42:15] Ryan Stout(@ryanstout):@elia I think you worked on the hashing stuff, hit me up when you get time. I've got a question, but I can do a PR fix. ---------------------------------------------------------------------------------------------------- [18:36:05] Vitor Capela(@dodecaphonic):I'm mapping a library with the classic case of taking a callback as a block. When it comes to executing the thing in an async test, however, I get `undefined is not a function`. Analyzing it further, It boils down to a NoMethodError calling `continue_async` on nil. Any tips? ---------------------------------------------------------------------------------------------------- [18:58:17] Vitor Capela(@dodecaphonic):I have a lot of other async tests running fine, using Promises as the async mechanism. When I go to raw procs or even passing lambdas, I get that sort of error. ---------------------------------------------------------------------------------------------------- [19:28:59] Elia Schito(@elia):Maybe the block is instance evaled so that self is no more the example ---------------------------------------------------------------------------------------------------- ############################## [2015-04-17] ############################## [17:25:33] Forrest Chang(@fkchang):@elia @adambeynon @meh what is the general guidelines on using Native vs not. I've been doing some stuff w/google maps and some other js wrappers to that, and I've been mixing it up, partly because I can only get some things to work w/o calling Native and using x strings. From the Ruby perspective, I'd like to use Native all the time, and minimize my use of x strings ---------------------------------------------------------------------------------------------------- [17:26:45] meh.(@meh):@fkchang personally I use it as a helper to build wrappers around libraries, but what's not working that forces you to go with x-strings? ---------------------------------------------------------------------------------------------------- [21:11:04] Forrest Chang(@fkchang):@meh I suspect it was a non correct conversion of types a few layers down, i.e. map.bounds.extendWith(arrayOfJsObjs), where I originally called Native on map. I started w/JS and converted, I couldn't get it all working, and ended up doing the x strings wrapping that worked ---------------------------------------------------------------------------------------------------- ############################## [2015-04-19] ############################## [14:24:55] Kurtis Rainbolt-Greene(@krainboltgreene):@elia: Any plans to implement URI? ---------------------------------------------------------------------------------------------------- [17:32:16] Elia Schito(@elia):@krainboltgreene I started about a year ago I think but there were too many issues with regexps… ---------------------------------------------------------------------------------------------------- ############################## [2015-04-20] ############################## [00:48:49] Kurtis Rainbolt-Greene(@krainboltgreene):@elia: Alright, I'm going to work on it I think.

I will not, if you're using rails and opal-rails that jquery and opal-jquery are already bundled in. This time around I decided not to fight what was already there, but I strive towards jQuery free apps where possible ---------------------------------------------------------------------------------------------------- [16:51:31] meh.(@meh):@fkchang yeah, I tried to look but I couldn't see any issues with the inspect code, I'll have to dig deeper, did you try with other browsers? ---------------------------------------------------------------------------------------------------- [16:53:20] Forrest Chang(@fkchang):@meh I should try, but I backed away to get the task at hand finished.

I'm trying to run some code whether the promise is resolved or rejected, for instance in an HTTP request via opal-query: ``` HTTP.get('/fooling/jsonstest').then do alert 'good!' end.fail do alert 'oops!' end.always do alert 'finished' end ``` But the "always" block doesn't actually happen always. My expectation would be to get "good!" + "finished" alerts if the request was successful, and "oops!" + "finished" alerts if not. Any ideas? ---------------------------------------------------------------------------------------------------- [18:42:09] Adam Beynon(@adambeynon):@jaredcwhite that would be my assumption as well. I’ll check with @meh as he implemented it. ---------------------------------------------------------------------------------------------------- [18:42:14] Adam Beynon(@adambeynon):but yes, that should be the case ---------------------------------------------------------------------------------------------------- [18:51:46] meh.(@meh):@adambeynon @jaredcwhite it's like that by design, I don't know if it would be possible to implement it like that since a rejection is short circuiting. ---------------------------------------------------------------------------------------------------- [18:52:41] Adam Beynon(@adambeynon):@meh does Promises A have anything similar to #always? ---------------------------------------------------------------------------------------------------- [18:53:14] meh.(@meh):adambeynon, I don't remember, I think not, #always was more like an lias to .then(&block).fail(&block) ---------------------------------------------------------------------------------------------------- [00:29:54] Ryan Stout(@ryanstout):does that give a significant performance improvement? ---------------------------------------------------------------------------------------------------- [04:44:37] George Plymale II(@ylluminarious):sorry, don't mean to interrupt the conversation here, but just a quick question about accessing js properties in native opal. i have an example here: http://cl.ly/0K0x1k3H1t0Y that models a problem i am currently having. if you run the code, you get an error saying that `element.$name()` is undefined (which is the code on line 21). the only way i can see to bypass this error is to do something like this: http://cl.ly/1I2O1t3X0W0O. however, i'd prefer to find a solution for this in native opal. does anyone have any ideas? ---------------------------------------------------------------------------------------------------- ############################## [2015-04-24] ############################## [22:24:12] Elia Schito(@elia):jk ---------------------------------------------------------------------------------------------------- [22:24:24] meh.(@meh):I didn't consider always would have to act that way ---------------------------------------------------------------------------------------------------- [22:26:21] Elia Schito(@elia):btw optparse implementation (by nobu + another guy) is really a mess ---------------------------------------------------------------------------------------------------- [22:26:35] Elia Schito(@elia):or at least not easily readable ---------------------------------------------------------------------------------------------------- [22:28:00] Ryan Stout(@ryanstout):@elia I've tried to read through optparse, its rough :-) ---------------------------------------------------------------------------------------------------- [22:28:07] Ryan Stout(@ryanstout):I think it's really really old though ---------------------------------------------------------------------------------------------------- [22:29:01] Elia Schito(@elia):yea, there are blobs of code that look a lot like C ---------------------------------------------------------------------------------------------------- [22:30:29] Ryan Stout(@ryanstout):@elia or @adambeynon any idea why require '...' wouldn't actually include code when using Opal.compile ---------------------------------------------------------------------------------------------------- [22:30:34] Ryan Stout(@ryanstout):or am I missing something obvious ---------------------------------------------------------------------------------------------------- [22:32:27] Elia Schito(@elia):Opal.compile == Opal::Compiler.new(…).compile irrc ---------------------------------------------------------------------------------------------------- [22:33:07] Elia Schito(@elia):I suggest using: `compiler = Opal::Compiler.new(…); compiler.compile; compiler.requires` which gives you the list of requires from a compiled file ---------------------------------------------------------------------------------------------------- [22:33:35] Elia Schito(@elia):Opal::Compiler is low level, Opal::Builder takes care of fetching requires ---------------------------------------------------------------------------------------------------- [22:34:15] Elia Schito(@elia):@ryanstout when `requirable: true` is passed to Opal::Compiler it will compile inside `Opal.module` (js) ---------------------------------------------------------------------------------------------------- [22:34:42] Elia Schito(@elia):then you'll be able to require the file in opal-land with Kernel#require (opal) ---------------------------------------------------------------------------------------------------- [22:35:07] Elia Schito(@elia):_inception, as always_ ---------------------------------------------------------------------------------------------------- [22:35:24] Ryan Stout(@ryanstout):so maybe I should be using Opal::Builder. The problem is right now I have to start with a string of code. Would that still work? ---------------------------------------------------------------------------------------------------- [22:35:31] Ryan Stout(@ryanstout):or is Opal::Builder for working with files? ---------------------------------------------------------------------------------------------------- [22:35:51] Elia Schito(@elia):Use Opal::Builder#build_str ---------------------------------------------------------------------------------------------------- [22:36:20] Elia Schito(@elia):alas you have no other option than checking the source to see docs, params, etc. ---------------------------------------------------------------------------------------------------- [22:36:55] Ryan Stout(@ryanstout):no worries, I can read through the source :-) ---------------------------------------------------------------------------------------------------- [22:37:05] Ryan Stout(@ryanstout):cool, that might have answered another question I had ---------------------------------------------------------------------------------------------------- [22:37:48] Elia Schito(@elia):feel free to add documentation! :P ---------------------------------------------------------------------------------------------------- [22:43:41] Ryan Stout(@ryanstout):is Opal::Builder going away in 0.8? ---------------------------------------------------------------------------------------------------- [22:47:24] Elia Schito(@elia):no, but I think it will stick with current 0.7 implementation, that kinda reinvents the sprockets wheel ---------------------------------------------------------------------------------------------------- [00:34:12] Forrest Chang(@fkchang):@elia @adambeynon so what's in 0.7.2? ---------------------------------------------------------------------------------------------------- [00:37:04] Elia Schito(@elia):Basically just fixed ENGINE_VERSION inside Opal ---------------------------------------------------------------------------------------------------- [00:37:55] Elia Schito(@elia):https://github.com/opal/opal/pull/806 ---------------------------------------------------------------------------------------------------- [05:48:44] Penn Su(@pencilcheck):so opal is rubyfire? ---------------------------------------------------------------------------------------------------- [06:08:21] Adam Beynon(@adambeynon):@pencilcheck rubyfire is a MVC style library that uses Opal. It is being extracted from a production app, but isn’t yet ready (taking longer than expected/not enough time to finish getting it ready) ---------------------------------------------------------------------------------------------------- [06:08:31] Adam Beynon(@adambeynon):it is similar to vienna, which is on github already ---------------------------------------------------------------------------------------------------- [06:10:20] Penn Su(@pencilcheck):Ah I see ---------------------------------------------------------------------------------------------------- [15:29:33] Jared White(@jaredcwhite):@adambeynon @meh Hmm, this feels like a bug to me. For example, using jQuery directly this works as I would expect: ``` $.get('/fooling/jsontest').done(function() { alert('$.get done!'); }).fail(function() { alert('$.get failed!'); }).always(function() { alert( "$.get finished" ); }); ``` ---------------------------------------------------------------------------------------------------- [15:33:45] Jared White(@jaredcwhite):There, the code in the always callback is run whether or not the promise was resolved or rejected ---------------------------------------------------------------------------------------------------- [15:34:30] meh.(@meh):@jaredcwhite makes sense, I'll give it a shot. ---------------------------------------------------------------------------------------------------- [17:33:40] Forrest Chang(@fkchang):@meh get a chance to check the paggio project? ---------------------------------------------------------------------------------------------------- [17:33:52] meh.(@meh):@fkchang not yet, I'll do it after the Promise stuff ---------------------------------------------------------------------------------------------------- [17:34:00] Forrest Chang(@fkchang):ok, cool ---------------------------------------------------------------------------------------------------- [20:21:41] Jared White(@jaredcwhite):@meh Cool, thanks ---------------------------------------------------------------------------------------------------- [21:03:31] ylluminate(@ylluminate):@ylluminate applauds @AstonJ & @elia for Twitter crusade. ---------------------------------------------------------------------------------------------------- [21:27:16] Ryan Stout(@ryanstout):did 0.7.2 go back to sprockets, or is that waiting for 0.8? ---------------------------------------------------------------------------------------------------- [21:27:55] ylluminate(@ylluminate):I thought I saw .8 ---------------------------------------------------------------------------------------------------- [21:36:40] AstonJ(@AstonJ):Thanks @ylluminate - I’m glad that conversation happened, because I will feel less guilty about supporting, promoting and helping Volt now; nobody can say we didn’t try our hardest to try and get DHH to adopt Opal/full stack Ruby. ---------------------------------------------------------------------------------------------------- [21:38:29] Elia Schito(@elia):@ryanstout 0.7.2 just fixes RUBY_ENGINE_VERSION ---------------------------------------------------------------------------------------------------- [21:39:09] Elia Schito(@elia):unless I messed up very badly :fearful: ---------------------------------------------------------------------------------------------------- [21:39:23] Ryan Stout(@ryanstout):@AstonJ DHH has a vested interest to keep things the same. (imho) ---------------------------------------------------------------------------------------------------- [21:39:33] Ryan Stout(@ryanstout):@elia no, I was just curious ---------------------------------------------------------------------------------------------------- [21:42:05] Elia Schito(@elia):I think opal should be a good rails citizen, and rails & volt can be friends too :) I don't like confrontational style very much as it yields very few results ---------------------------------------------------------------------------------------------------- [21:42:48] Ryan Stout(@ryanstout):true :-) ---------------------------------------------------------------------------------------------------- [21:42:56] Ryan Stout(@ryanstout):yea, I like DHH actually :-) ---------------------------------------------------------------------------------------------------- [21:43:10] Ryan Stout(@ryanstout):just saying he has more incentive to move slowly, because too many changes and he'll lose people ---------------------------------------------------------------------------------------------------- [21:43:22] Ryan Stout(@ryanstout):which is very understandable ---------------------------------------------------------------------------------------------------- [22:06:50] AstonJ(@AstonJ):I like DHH as well, I have a huge amount of respect for him both in relation to Ruby related stuff and personal stuff. I like that he stands up for what he believes in (often for the underdogs or those who are persecuted - something that I think takes guts) and of course I love Rails. But I love Ruby more. I think, like @ryanstout, that Rails has stagnated. It is 10 years old, and although they have done an amazing job to remain relevant, apps (note I don't say 'the web') is a very different place now. I think MVVm is more relevant, I think isomorphic Ruby is nicer (which should equate to better productivity), I think scalability is no longer an option and I think bags of old code and functionality that nobody uses anymore is a hinderance. This is why I am so excited about Volt - it is fresh, and has that certain something, that pizazz, that I think can capture the imagination of the next generation of developers/development. ---------------------------------------------------------------------------------------------------- [22:08:19] AstonJ(@AstonJ):I also think there is only so much you can achieve by being nice @elia, we've tried to get DHH to consider Opal for a while now, you and Adam even went to the trouble of giving him Active Support when that was his main criticism! I think we just have to accept that we have to make our own path. And I think it's totally fine that there will be inroads back to us (developers leaving Rails, Ember, etc) ...and that is only down to them, for not recognising that people wanted a pure (ish) Ruby option and all the other things that Volt and Opal is offering us. ---------------------------------------------------------------------------------------------------- [22:11:40] Elia Schito(@elia):I have no need to convince dhh to adopt opal, nicely or otherwise, having people that care and build awesome stuff is enough and in the long run all other players will notice. Rails had plenty of criticism, but I guess by now is quite established tech ---------------------------------------------------------------------------------------------------- [22:13:17] Elia Schito(@elia):I'd rather see energy spent making opal docs and improving the experience for newcomers ---------------------------------------------------------------------------------------------------- [22:13:51] Elia Schito(@elia):another example: RSpec prospers even if dhh kinda hates it ---------------------------------------------------------------------------------------------------- [22:14:56] Elia Schito(@elia):also the small part of activesupport I implemented was for me :P ---------------------------------------------------------------------------------------------------- [22:16:01] AstonJ(@AstonJ):It is the logical choice imo. Rails is Ruby, and most Rubyists love Ruby and want to write Ruby not JS. But yeah I agree with you, docs are severely lacking for Opal - we need some newbie guides. I keep toying with the idea of doing screen casts at Metaruby.com - just can’t fidn the time. ---------------------------------------------------------------------------------------------------- [22:18:57] meh.(@meh):I don't care either way, I just wanted Ruby in the browser :D ---------------------------------------------------------------------------------------------------- [22:19:40] Elia Schito(@elia):that's how we roll ---------------------------------------------------------------------------------------------------- [22:19:42] Elia Schito(@elia):lol ---------------------------------------------------------------------------------------------------- [22:20:31] AstonJ(@AstonJ):Me too @meh!

May I ask if there are some release notes. ---------------------------------------------------------------------------------------------------- [16:55:24] meh.(@meh):@jaredcwhite try Promise#always on master, it should work as expected now. ---------------------------------------------------------------------------------------------------- [17:54:30] meh.(@meh):@fkchang found the issue, the loop is actually an Opal bug, `string.gsub(/^[ \t]{#{string.scan(/^[ \t]*(?=\S)/).min.size rescue 0}}/, '')` causes an infinite loop ---------------------------------------------------------------------------------------------------- [17:59:55] meh.(@meh):@fkchang and I just realized it's actually a bug that I opened on Dec 15, 2013, https://github.com/opal/opal/issues/457 ---------------------------------------------------------------------------------------------------- [18:00:38] meh.(@meh):@fkchang it works on lissio because it doesn't use `Paggio::Formatter` ---------------------------------------------------------------------------------------------------- ############################## [2015-04-27] ############################## [00:10:53] Elia Schito(@elia):@bwl21 https://github.com/opal/opal/blob/master/CHANGELOG.md it's a super micro release ---------------------------------------------------------------------------------------------------- [10:09:51] Vais Salikhov(@vais):@meh @fkchang the fix for #457 is on the opal master branch :) ---------------------------------------------------------------------------------------------------- [14:59:15] Jared White(@jaredcwhite):@meh I'd love to try out your fix for Promise#always -- however I can't seem to run anything on the latest Opal master. I had updated another project to master a few days ago, and run into a huge issue and figured maybe I was doing something wrong and reverted, but now I just updated a simple test project and ran into the same issue. ---------------------------------------------------------------------------------------------------- [14:59:21] Jared White(@jaredcwhite):[Error] NameError: uninitialized constant Object::Document (anonymous function) (kernel.js, line 1137) $const_missing (module.js, line 329) get (runtime.js, line 75) (anonymous function) (index, line 214) global code (index, line 246) ---------------------------------------------------------------------------------------------------- [14:59:58] Jared White(@jaredcwhite):The issue seems to be that a bunch of extra library files (the opal-jquery stuff for example), as well as my own asset files, simply aren't being loaded. Maybe a Sprockets issue? ---------------------------------------------------------------------------------------------------- [15:01:33] Jared White(@jaredcwhite):Sorry -- I misspoke -- the compiled JS is loaded into the browser, but it's not accessible in the runtime context. For example, document.js is loaded from opal-jquery, but if I go to the console and type "Opal.Document" it is undefined. ---------------------------------------------------------------------------------------------------- [15:03:18] Jared White(@jaredcwhite):@adambeynon @fkchang BTW, I'm going to be sending out the next issue of the Opalist newsletter on Wednesday, so if you have any content/links you'd like me to include let me know in the next day or so. Thanks! ---------------------------------------------------------------------------------------------------- [22:09:52] Nathan Hopkins(@hopsoft):can someone demonstrate how to access a method on a global object. i'm using vue.js & would like to do this from opal. note `Vue` is a global. ``` Vue.directive("html-with-newlines", function (value) { this.el.innerHTML = String(value).replace(/\n/g, '
'); }); ``` ---------------------------------------------------------------------------------------------------- [22:10:43] Elia Schito(@elia):@hopsoft Easiest way is probably through `Native()` ---------------------------------------------------------------------------------------------------- [22:12:17] Nathan Hopkins(@hopsoft):I'm trying Native, but am getting: Uncaught NoMethodError: undefined method `directive' for # ---------------------------------------------------------------------------------------------------- [22:12:49] Elia Schito(@elia):``` Vue = Native(`Vue`) Vue.directive('html-with-newlines', -> value { Native(`this`)[:el].innerHTML = String(value).gsub("\n", '

I had gone off the idea, but I am thinking about doing screen casts at www.metaruby.com again to be a bit like egghead.io but with a forum as well. We were thinking of Voltcasts over at Volt, but I think a broader scope would help the whole Opal (/Ruby) community. What do you guys think? ---------------------------------------------------------------------------------------------------- [16:00:04] Adam Beynon(@adambeynon):@AstonJ of course. Railscasts was/is huge for rails uptake ---------------------------------------------------------------------------------------------------- [16:00:07] Elia Schito(@elia):> @AstonJ I’m not too woried about opal being “officially” supported in rails, in the same way that Haml isn’t, nor Slim, nor RSpec, etc completely agree ---------------------------------------------------------------------------------------------------- [16:01:39] Rick Carlino(@RickCarlino):@AstonJ : I've been doing more content creation out of my blog these days (www.datamelon.io/blog). If you want an guest/affiliate writer for content creation, let me know. I've got some Volt stuff in the works. ---------------------------------------------------------------------------------------------------- [16:01:42] Elia Schito(@elia):"Voltcasts" would be awesome, ppl need "how do I …" style tutorials ---------------------------------------------------------------------------------------------------- [16:01:56] Rick Carlino(@RickCarlino):Hell, is there a curated email list for the Opal / Volt community yet? ---------------------------------------------------------------------------------------------------- [16:02:34] Adam Beynon(@adambeynon):We do, yeap: http://www.opalist.co ---------------------------------------------------------------------------------------------------- [16:02:52] Adam Beynon(@adambeynon):new (only 1 mailing so far), but will be a nice central place for updates ---------------------------------------------------------------------------------------------------- [16:03:21] Rick Carlino(@RickCarlino):Awesome. I'll let you guys know when new content is up. ---------------------------------------------------------------------------------------------------- [16:07:10] AstonJ(@AstonJ):There’s Opalist.co - Adam beat me to it :p Rick, blog posts sound cool! I think we could probably keep a list of all publised posts on the Volt site somewhere, that will help for people clicking through and for SEO. I’ll run this past Ryan later. ---------------------------------------------------------------------------------------------------- [16:12:33] Elia Schito(@elia):@adambeynon I think we should promote the ML on opalrb.org and in the README, @jaredcwhite mind doing a PR? ---------------------------------------------------------------------------------------------------- [16:14:34] AstonJ(@AstonJ):Agree @elia - also add everything else that’s using Opal too? Such as Volt and Clearspring and Fire and I think even Active Support isn’t even mentioned on the site? ---------------------------------------------------------------------------------------------------- [16:15:29] AstonJ(@AstonJ):Btw @adambeynon, I think the link to my post is still broke on the RubyFire site ---------------------------------------------------------------------------------------------------- [16:15:58] Elia Schito(@elia):Yes I'll be glad to accept PRs and I think @adambeynon would agree to even give commit access to opalrb.org if a maintainer arises, docs really need some love ---------------------------------------------------------------------------------------------------- [16:21:44] AstonJ(@AstonJ):Nice. I am currently going through the Volt docs, I’ll try to move on to Opal after that. If any of you can write up some rough docs, I don’t mind trying to edit or re-write them?

WHen I resume, I'll try to file something ---------------------------------------------------------------------------------------------------- [15:25:51] Forrest Chang(@fkchang):@AstonJ Related to your twitter crusade, I honestly don't understand why more Ruby web devs are diving into opal. GIven all the conference rejections I've gotten, I obviously must not be phrasing the message right. Lately, I've been thinking of "why wouldn't someone use opal for web if they're already a rubyist". As far as I can tell it's existing investment(say lots of Backbone/Angular whatever), and that might in the team members mentality, raw performance, or just thinking that opal is a toy ---------------------------------------------------------------------------------------------------- [15:26:00] Forrest Chang(@fkchang):otherewise, I can't think of any good reasons ---------------------------------------------------------------------------------------------------- [15:42:03] Adam Beynon(@adambeynon):@fkchang the lack of large open-source examples could hinder it as well ---------------------------------------------------------------------------------------------------- [15:42:12] Adam Beynon(@adambeynon):nothing like a large code base to show development stylw ---------------------------------------------------------------------------------------------------- [15:42:16] Adam Beynon(@adambeynon):style* ---------------------------------------------------------------------------------------------------- [15:47:56] AstonJ(@AstonJ):@fkchang Funnily enough, I have just been having a short exchange with DHH over email. He says he can only fit so many causes on his plate - and that right now Ruby in the browser isn’t one of them. I’ve asked him if there’s anything we can do to change his mind. **EDIT**: he’s just got back to me saying that we are unlikely to sway him :-(. Like you, I think there must be other reasons that is part of his reasoning (probably not wanting to re-write all that Coffescript for one, followed by other smaller factors). ---------------------------------------------------------------------------------------------------- [15:48:00] AstonJ(@AstonJ):But that’s ok, at least we tried, and tbh, it makes me feel a lot less guilty about supporting and promoting Volt - because at least nobody can say we didn’t try our hardest to get Opal in Rails. Not that Volt’s only appeal is Opal, the whole package in Volt is pretty awesome, and on many levels, a step-up from Rails in many regards. It’s fresh, with ideas to match. Lean (does not have baggage of legacy frameworks). Scalable, thanks to tech like JRuby compatible and web sockets. Cutting edge (adopted the current best methodologies) and of course gives us the power of Ruby in the browser (and minimises our exposure to JS!! haha) ---------------------------------------------------------------------------------------------------- [15:48:27] AstonJ(@AstonJ):@adambeynon - I think Volt is going to be Opal’s first killer app ;-) ---------------------------------------------------------------------------------------------------- [15:49:18] Rick Carlino(@RickCarlino):Sad to hear @AstonJ . That's the route I'm taking- I'm trying my hardest to promote Volt. It's the best road forward for the community at this point. We just need to sell it. And sell it hard. ---------------------------------------------------------------------------------------------------- [15:49:55] Adam Beynon(@adambeynon):@AstonJ I’m not too woried about opal being “officially” supported in rails, in the same way that Haml isn’t, nor Slim, nor RSpec, etc ---------------------------------------------------------------------------------------------------- [15:52:04] AstonJ(@AstonJ):Completely agree @RickCarlino - we have started a strategies team at Volt if you (or anyone else here) is interested in joining :) ---------------------------------------------------------------------------------------------------- [15:52:28] AstonJ(@AstonJ):All Volt needs is _one_ killer app. And I really don’t think it will be long before we see one :D ---------------------------------------------------------------------------------------------------- [15:53:06] AstonJ(@AstonJ):@adambeynon It just would have been nice (and fitting) that’s all. Look what Rails did for CS, completely unworthy imo. ---------------------------------------------------------------------------------------------------- ############################## [2015-04-29] ############################## [10:42:19] Elia Schito(@elia):where's the batman emoji ---------------------------------------------------------------------------------------------------- [10:42:21] Elia Schito(@elia):! ---------------------------------------------------------------------------------------------------- [10:48:37] Elia Schito(@elia):@adambeynon ``` _ ~/~/~/~/~/~/\~~/~/ _ _ \/__/_|/_/_/_|_/_/ _____*~~~ ** ~~~*_____ \____/ __* ___ |\__/| ___ *__ _* / 888~~\__(8OO8)__/~~888 \ *_ _* /88888888888888888888888888\ *_ * |8888888888888888888888888888| * /~* \8888/~\88/~\8888/~\88/~\8888/ *~ / ~* \88/ \/ (88) \/ \88/ *~ / ~* \/ \/ \/ *~ / ~~*_ _*~~/ / ~~~~~*___ ** ___*~~~~~ / / ~ ~ / / / / / / / / t__n__r__ / / | ####### | / ___ | ####### | ____i__ / / _____p_____l_l____ | ####### | | ooooo | qp i__p__ / | ############## | | ####### |__l___xp____| ooooo | |~~~~| oooo |_I_| ############## | | ####### |oo%Xoox%ooxo| ooooo |p__h__|##%#| oooo |ooo| ############## | | ####### |o%xo%%xoooo%| ooooo | |#xx%| oooo |ooo| ############## | | ####### |o%ooxx%ooo%%| ooooo |######|x##%| oooo |ooo| ############## | | ####### |oo%%x%oo%xoo| ooooo |######|##%x| oooo |ooo| ############## | | ####### |%x%%oo%/oo%o| ooooo |######|/#%x| oooo |ooo| ############## | | ####### |%%x/oo/xx%xo| ooooo |######|#%x/| oooo |ooo| ############## | | ####### |xxooo%%/xo%o| ooooo |######|#^x#| oooo |ooo| ############## | | ####### |oox%%o/x%%ox| ooooo |~~~$~~|x##/| oooo |ooo| ############## | | ####### |x%oo%x/o%//x| ooooo |_KKKK_|#x/%| ooo~\|ooo|~\############## | ~\####### |oox%xo%%oox%~\ooooo |_|~|~\|xx%/| ooo ||oHo| |####AAAA###### |h||##XX### |x%x%WWx%%/ox||ooDoo |_| |Y||xGGx| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | ~~~~~~~ ``` ---------------------------------------------------------------------------------------------------- [10:51:18] Vais Salikhov(@vais):HOLY BATMAN!

This seems like a really good, fast-track way to get info and quality screencasts out there without too much hassle for devs. What does everyone else think about this idea? ---------------------------------------------------------------------------------------------------- [13:25:14] Elia Schito(@elia):@fazibear http://opalrb.org/try/?code:%60%0Avar%20Test%3B%0A%0ATest%20%3D%20(function()%20%7B%0A%20%20function%20Test(a%2C%20b)%20%7B%0A%20%20%20%20console.log(a)%3B%0A%20%20%20%20console.log(b)%3B%0A%20%20%20%20this.a%20%3D%20a%3B%0A%20%20%20%20this.b%20%3D%20b%3B%0A%20%20%7D%0A%0A%20%20Test.prototype.get_a%20%3D%20function()%20%7B%0A%20%20%20%20return%20this.a%3B%0A%20%20%7D%3B%0A%0A%20%20Test.prototype.get_b%20%3D%20function()%20%7B%0A%20%20%20%20return%20this.b%3B%0A%20%20%7D%3B%0A%0A%20%20return%20Test%3B%0A%0A%7D)()%3B%0A%60%0A%0Aclass%20RTest%20%3C%20%60Test%60%0A%20%20def%20self.new(a%2Cb)%0A%20%20%20%20%25x%7Breturn%20new%20Test(a%2Cb)%3B%7D%0A%20%20end%0A%20%20%0A%20%20alias_native%20%3Aget_a%0Aend%0A%0Aputs%20RTest.new(1%2C2)%0Aputs%20RTest.new(3%2C4).get_a%0Aputs%20%60new%20Test(1%2C2)%60 ---------------------------------------------------------------------------------------------------- [13:48:45] Michał Kalbarczyk(@fazibear):@elia, thanks, now I get it :) ---------------------------------------------------------------------------------------------------- [14:37:32] Forrest Chang(@fkchang):@AstonJ screencasts is still on list of things to do. the opalist mailing list is giving some sort of deadline incentive to churn out all the material that's been piling up that I've meant to publish in some form or another. I was really hoping to come up with that smalltalk/lisp machine cool tooling I hinted at w/opal-inspector, but stalled waiting for the method/comment lookup stuff in opal. @adambeynon said it's still on his list though. Maybe @vais knows enough to put that in. I also thought I might be able to fake some of that functionality (small talk object browser type functionality) if I could programmatically call source maps. At least enough to make a really compelling video to inspire ppl ---------------------------------------------------------------------------------------------------- [14:47:52] Forrest Chang(@fkchang):@elia @adambeynon any of you guys use opal-jquery against IE8? Having a problem, suspect that self.new breaks on IE8 coz new is a reserved word and won't work on IE8 ---------------------------------------------------------------------------------------------------- [14:48:19] Elia Schito(@elia):@fkchang I think it's fixed on master ---------------------------------------------------------------------------------------------------- [14:53:50] Forrest Chang(@fkchang):@elia is opal-jquery master against 0.8 ? ---------------------------------------------------------------------------------------------------- [15:00:06] Elia Schito(@elia):@fkchang opal master should be enough, opal-jquery master is probably a good idea too ---------------------------------------------------------------------------------------------------- [15:26:44] AstonJ(@AstonJ):Sounds good @fkchang. Quite a few people have expressed an interest in doing screen casts now which is great :) I think we definitely need some beginner tuts that introduce the concepts - just so people can get their heads around the idea. ---------------------------------------------------------------------------------------------------- [15:40:14] Forrest Chang(@fkchang):@elia we may submit a PR with the same self.new fix in the 0.7 since 0.8 doesn't work for us yet ---------------------------------------------------------------------------------------------------- [15:40:37] Elia Schito(@elia):sure, branch is 0-7-stable ---------------------------------------------------------------------------------------------------- [15:40:57] Forrest Chang(@fkchang):@AstonJ it's cool that there is interest in screen casts. I think beginner material of all kinds are needed. ---------------------------------------------------------------------------------------------------- [15:41:24] Forrest Chang(@fkchang):I'd consider writing a book, but then I'd have to understand all that stuff ;) , and then find the time to do it ---------------------------------------------------------------------------------------------------- [15:41:45] Forrest Chang(@fkchang):I think something that comprehensive will help, and more open source examples ---------------------------------------------------------------------------------------------------- [15:43:54] Forrest Chang(@fkchang):I suspect one reservation people have is that they don't think opal is ready for production. Comprehensive instructions/examples can help. Or it's a case of "I'd love to do Ruby in the browser, but I don't know how to XXX" and at the moment, googling doesn't yield the answer. ---------------------------------------------------------------------------------------------------- [15:44:55] Elia Schito(@elia)::+1: ---------------------------------------------------------------------------------------------------- [16:09:10] AstonJ(@AstonJ):@fkchang yeah, book writing is haaard (at least if you are to do it properly). I started work on a Rails book once, but decided against it because Rails changes every year and you would need to make a long term commitment, keeping the book updated etc I agree with you about the reservations people might have - Opal really could do with a few screencasts on how to use it (say in Rails). It's actually one of the reasons why I think Volt is appealing, cos Ryan has done all the nitty gritty and if you learn Volt, you also end up learning all those things that you might otherwise have thought about using Opal for. I also think, that maybe as time goes on, Opal becomes the 'heart' of frameworks and tools like Volt, Fire and Clearspring, rather than something used independently. This I think makes sense on a number of fronts - the Opal team then only need to spend time helping a smaller number of devs - rather than thousands for example. ---------------------------------------------------------------------------------------------------- [21:09:24] Rick Carlino(@RickCarlino):What is this `magic-breakpoint` I keep hearing about? ---------------------------------------------------------------------------------------------------- [21:09:34] Rick Carlino(@RickCarlino):Is that a debug tool? ---------------------------------------------------------------------------------------------------- [23:43:21] Elia Schito(@elia):@RickCarlino never heard of that… ---------------------------------------------------------------------------------------------------- [00:11:46] Penn Su(@pencilcheck):@ryanstout what do you mean? the compiled code? or the data? ---------------------------------------------------------------------------------------------------- [00:11:50] Penn Su(@pencilcheck):or marshaling? ---------------------------------------------------------------------------------------------------- [00:32:59] Ryan Stout(@ryanstout):@elia the data. ---------------------------------------------------------------------------------------------------- [00:33:20] Ryan Stout(@ryanstout):Mostly I'm wishing json had a date type. ---------------------------------------------------------------------------------------------------- [02:34:45] Forrest Chang(@fkchang):@jaredcwhite ok, so I have about 2.5 hours. On it ---------------------------------------------------------------------------------------------------- [02:35:27] Forrest Chang(@fkchang):@jaredcwhite the symptoms in that opal issue look very similar to what i remember seeing. I'm wondering if we need to do additional requiring in 0.8 vs 0.7 ---------------------------------------------------------------------------------------------------- [03:08:59] Vais Salikhov(@vais):@AstonJ, this is my "two cents" only, please take with a grain of salt: Mongo is the elephant in the room. Nevermind its recent fall from grace, the meteoric rise and fall among the hipsters. The real issue is the disconnect between the general appeal and applicability of Volt on the one hand, and the narrow scope of Mongo on the other. Volt's association with Mongo will serve to hinder PR efforts attempted prior to the release of the data provider api. That is, if you want to talk about Volt and Rails in the same sentence, the Mongo-only issue has to be addressed. ---------------------------------------------------------------------------------------------------- [03:10:16] Ryan Stout(@ryanstout):@vais We're adding support for other databases, postgres support should be out shortly. ---------------------------------------------------------------------------------------------------- [03:16:59] Jared White(@jaredcwhite):@vais @ryanstout That's the only significant reason why I've been hesitant to dive deep into Volt. Knowing that postgres support is coming soon, I'm very excited to check that out! ---------------------------------------------------------------------------------------------------- [03:17:37] Ryan Stout(@ryanstout):I wish I had gotten the memo that everyone hated mongo before I started :-) Though that was two years ago, so everyone didn't then :-) ---------------------------------------------------------------------------------------------------- [03:17:52] Ryan Stout(@ryanstout):also, mongo was easier for me to implement due to a few reasons. ---------------------------------------------------------------------------------------------------- [03:56:35] Jared White(@jaredcwhite):Heh...3 years ago I built a Rails app using CouchDB. Found out that was even dumber than going with Mongo...ended up porting to postgres. Live and learn! ---------------------------------------------------------------------------------------------------- [04:02:45] ylluminate(@ylluminate):get excited @gabrielrios - note the very soon support of pgsql! ---------------------------------------------------------------------------------------------------- [04:04:40] ylluminate(@ylluminate):we used couch back about 5 years ago on a project @jaredcwhite. went surprisingly well. i still miss it sometimes, but pgsql just offers too much utility ---------------------------------------------------------------------------------------------------- [04:21:30] Forrest Chang(@fkchang):@jaredcwhite http://funkworks.blogspot.com/2015/04/ruby-fying-javascript-avoiding-jquery.html ---------------------------------------------------------------------------------------------------- [05:02:41] Vais Salikhov(@vais):@ryanstout two years ago everyone was loving mongo :) But seriously, this is not about loving or hating Mongo - I summarized my thoughts on this [here](http://www.reddit.com/r/ruby/comments/33eu6t/volt_090_is_here_and_its_amazing_xpost/cqkcmf2) in response to the 0.9.0 announcement. I really am excited about the promise of data provider API, and I know I'm not alone in this. I like to think that you tied Volt to Mongo on purpose, so that you get to build it out in relative calm, then drop Mongo and really take Volt public :) Cause there's no freaking chance in hell that a mongo-specific ruby framework is going to take the world by storm in 2015. But a storage-agnostic real-time isomorphic ruby framework that puts Rails to shame in terms of developer productivity just might ;) ---------------------------------------------------------------------------------------------------- [05:03:35] Ryan Stout(@ryanstout):@vais yea, I did mongo because it was fast to get up and running with. ---------------------------------------------------------------------------------------------------- [05:03:49] Ryan Stout(@ryanstout):(since Volt needs to parse queries and its easy to parse mongo queries) ---------------------------------------------------------------------------------------------------- [05:04:22] Ryan Stout(@ryanstout):@vais anyway, come chat in the volt gitter sometime if you want to chat more ---------------------------------------------------------------------------------------------------- [05:36:30] Jared White(@jaredcwhite):@fkchang got it, thanks!!! ---------------------------------------------------------------------------------------------------- [05:42:15] Ryan Stout(@ryanstout):does require_tree only work as a sprockets directive, or does it work directly in opal? ---------------------------------------------------------------------------------------------------- [06:23:31] Elia Schito(@elia):@ryanstout which version of Opal ? ---------------------------------------------------------------------------------------------------- [06:24:34] Elia Schito(@elia):on master I can tell it's parsed by the compiler and available as #required_trees iirc ---------------------------------------------------------------------------------------------------- [07:48:51] Elia Schito(@elia):@adambeynon ping ---------------------------------------------------------------------------------------------------- [07:50:23] Adam Beynon(@adambeynon):@elia yo yo ---------------------------------------------------------------------------------------------------- [07:52:10] Elia Schito(@elia):@adambeynon sup, anything you wanna take into 0.8 from this list https://github.com/opal/opal/milestones/0.8? ---------------------------------------------------------------------------------------------------- [07:53:15] Adam Beynon(@adambeynon):@elia hmmmmmmm, I had one thought which might help debugging. At the moment, when looking at stack traces, any blocks show up as $TMP_1, $TMP_2 etc, which isn’t very helpful. I thought about changing the temp variables names into something more useful ---------------------------------------------------------------------------------------------------- [07:53:25] Adam Beynon(@adambeynon):e.g. $block_in_array_each ---------------------------------------------------------------------------------------------------- [07:53:38] Elia Schito(@elia):that would be great ---------------------------------------------------------------------------------------------------- [07:53:54] Elia Schito(@elia):or even $Array_each ---------------------------------------------------------------------------------------------------- [07:55:06] Adam Beynon(@adambeynon):elia, yeap. its an easy fix, and would make debugging WAY easier. From what I can see, it would work in both chrome and safari in terms of stack traces ---------------------------------------------------------------------------------------------------- [07:55:19] Adam Beynon(@adambeynon):haven’t tried firefox, but I imagine it is a similar thingy ---------------------------------------------------------------------------------------------------- [07:59:38] Elia Schito(@elia):@adambeynon you already have it working locally? ---------------------------------------------------------------------------------------------------- [08:36:19] Elia Schito(@elia):I thought this was just local: https://travis-ci.org/opal/opal/jobs/60498552 ---------------------------------------------------------------------------------------------------- [08:37:19] Elia Schito(@elia):@adambeynon @vais you ever saw that ^^^? ---------------------------------------------------------------------------------------------------- [08:56:37] Vais Salikhov(@vais):@elia ow snap! Yes, I saw it while running specs on Chrome and on Chrome only. I suspect this has something to do with how the JS runtime is compiled, since on the same machine nodejs did not have a problem with it, and Chrome did, and both are V8. Well, actually, Chrome has a more recent V8 than node, so maybe its a newer version of node being used to run the specs on travis? ---------------------------------------------------------------------------------------------------- [09:01:50] Vais Salikhov(@vais):Anyhow, the fix would be to fiddle with the TOLERANCE constant here: https://github.com/opal/rubyspec/blob/master/spec_helper.rb#L44 ---------------------------------------------------------------------------------------------------- [09:02:21] Vais Salikhov(@vais):Currently `TOLERANCE = 0.00003 unless Object.const_defined?(:TOLERANCE)` ---------------------------------------------------------------------------------------------------- [09:04:08] Vais Salikhov(@vais):So, edit the spec_helper or define `TOLERANCE` before the specs are run. ---------------------------------------------------------------------------------------------------- [09:30:21] Elia Schito(@elia):@vais node v0.12 here, you have an earlier one? ---------------------------------------------------------------------------------------------------- [09:34:58] Vais Salikhov(@vais):$ node -v v0.10.35 ---------------------------------------------------------------------------------------------------- [09:35:14] Elia Schito(@elia):I guess we nailed it down ---------------------------------------------------------------------------------------------------- [09:35:44] Elia Schito(@elia):>> '%.8f' % (11226018484.0012 - 11226018484.001236) => "-0.00003624" ---------------------------------------------------------------------------------------------------- [09:37:34] Vais Salikhov(@vais):right, @elia, but I'm confused - I just did 2 PRs, one failed the other one didn't ---------------------------------------------------------------------------------------------------- [09:37:56] Elia Schito(@elia):My guess is that they're running on different machines ---------------------------------------------------------------------------------------------------- [09:38:08] Vais Salikhov(@vais):Hehe, that would explain it ---------------------------------------------------------------------------------------------------- [09:38:16] Elia Schito(@elia):and they're in the process of upgrading the default version of node ---------------------------------------------------------------------------------------------------- [09:38:22] Elia Schito(@elia):pushing a fix ---------------------------------------------------------------------------------------------------- [09:38:39] Vais Salikhov(@vais):Mystery solved :) ---------------------------------------------------------------------------------------------------- [09:39:25] Elia Schito(@elia):btw, 4.8k specs is awesome ---------------------------------------------------------------------------------------------------- [09:40:50] Vais Salikhov(@vais)::+1: ---------------------------------------------------------------------------------------------------- [10:04:42] Elia Schito(@elia):@vais so, you're still on the #format quest or you need another one? :P ---------------------------------------------------------------------------------------------------- [10:26:22] Vais Salikhov(@vais):@elia nope, that's 100% done.

I will comb through it again to see if there's anything I can pick off now that I've gained some experience with Opal ;) ---------------------------------------------------------------------------------------------------- [10:37:39] Vais Salikhov(@vais):That said, a lot of the issues are discussions, WIPs etc. I don't see anything wrong with having those around, as long as they don't go stale.

---------------------------------------------------------------------------------------------------- [23:17:04] Elia Schito(@elia):how so? ---------------------------------------------------------------------------------------------------- [23:17:11] meh.(@meh):krainboltgreene, even require doesn't do what you think it does ---------------------------------------------------------------------------------------------------- [23:17:19] Kurtis Rainbolt-Greene(@krainboltgreene):Would it be so terrible to assume all Dir, File, and Path domains refered to a "fake" filesystem loaded by Opal.environment?

So close, but so far ---------------------------------------------------------------------------------------------------- [00:34:13] Elia Schito(@elia):Have you googled the error already ? ---------------------------------------------------------------------------------------------------- [00:44:43] Forrest Chang(@fkchang):@elia seems like this might be it in general https://groups.google.com/a/chromium.org/forum/#!topic/chromium-extensions/T1IqBsNr1-U where it looks like I'd have to munge what the opal compiler gives ---------------------------------------------------------------------------------------------------- [00:52:04] Elia Schito(@elia):I think it can serialize with json the name which is a string and not the obj itself for obvious reasons ---------------------------------------------------------------------------------------------------- [01:10:52] Forrest Chang(@fkchang):Yeah, so the question is can we make opal objects json stringifyable? or do I munge the compiled output to force to_s or someting? @adambeynon ? ---------------------------------------------------------------------------------------------------- [01:12:02] Forrest Chang(@fkchang):otherwise fairly close to a chrome panel that you can have opal-irb in any opal app w/o having to build it in ---------------------------------------------------------------------------------------------------- [01:14:50] Forrest Chang(@fkchang):this unfortunately the last evaluated object, because everything has to be stringified? ---------------------------------------------------------------------------------------------------- [01:41:48] Forrest Chang(@fkchang):So it seems when it comes back, it loses the opal prototype ---------------------------------------------------------------------------------------------------- [01:42:07] Forrest Chang(@fkchang):unless @adambeynon or anyone else has any ideas, I think I'm going to give up on the chrome panel ---------------------------------------------------------------------------------------------------- [06:24:13] Adam Beynon(@adambeynon):@fkchang iirc, when I looked at it before, my plan of action was to inject the compiler/parser into the page itself, and the REPL was just a case of passing the string to the page context, doing the compiling there, and then returning the result ---------------------------------------------------------------------------------------------------- [06:24:40] Adam Beynon(@adambeynon):if you want to do object inspection, then all that logic and code etc would need to live in the page itself, and the extension just asks for the json representation ---------------------------------------------------------------------------------------------------- [06:25:01] Adam Beynon(@adambeynon):its all very awkward, but unfortunately thats the way it is ---------------------------------------------------------------------------------------------------- [06:25:11] Adam Beynon(@adambeynon):opal-parser.js could have all that logic baked in ---------------------------------------------------------------------------------------------------- [06:25:29] Adam Beynon(@adambeynon):so the chrome extension is just an interface to that logic ---------------------------------------------------------------------------------------------------- [14:11:55] Forrest Chang(@fkchang):@adambeynon what I believe is happening is that the chrome panel runs as it's own process, thus allowing it to have different js libs and what not. ```javascript chrome.devtools.inspectedWindow.eval``` runs it in the context of the inspected window and the result gets json-stringify-ed to be sent back to the chrome panel. If I understand your example, you want to inject the compiler into the page, and use ```javascript inspectedWIndow.eval``` to communicate w/that one? Hmm, I might be able to make that work, but it is convoluted. After killing a day yesterday, I think I'll let that digest a bit ---------------------------------------------------------------------------------------------------- [14:14:13] Forrest Chang(@fkchang):Though maybe just improving opal-irb and other tools so they have less dependencies and is easier to insert into ones app (mostly it's the dependencies that make that a little harder) might be better ROI ---------------------------------------------------------------------------------------------------- [14:16:46] Forrest Chang(@fkchang):@adambeynon did u have an idea of how u would inject the parser into the page? ---------------------------------------------------------------------------------------------------- [14:32:54] Forrest Chang(@fkchang):I suppose I could precompile the pertinent classes into a single js file and inject that. The problem I see w/that is that may or may not run if there is an opal version conflict, whereas the chrome panel way of doing it simply sends code across to be evaled in the inspected window's context w/o injecting possibly incompatible code. Not sure if it would be worth the time ---------------------------------------------------------------------------------------------------- [14:34:01] Elia Schito(@elia):I kinda like the irb solution more (as a safari user :P) ---------------------------------------------------------------------------------------------------- [14:39:53] Vais Salikhov(@vais):Guys, can someone please tell me how in the world this works: ``` $ bundle exec opal-repl >> puts "hool\u0007" hoola => nil >> puts "hool\u001b" hoole => nil ``` It's been driving me crazy for a couple of days already that I can't figure it out. @adambeynon any pointers where this transformation occurs in the parse/compile process? ---------------------------------------------------------------------------------------------------- [14:44:38] Elia Schito(@elia):@vais check the lexer too ---------------------------------------------------------------------------------------------------- [14:45:29] Elia Schito(@elia):``` > opal --sexp -Oe 'puts "hool\u0007"' (:call, nil, :puts, (:arglist, (:str, "hool\a"))) ``` ---------------------------------------------------------------------------------------------------- [14:48:17] Elia Schito(@elia):@vais probably `def read_escape` ---------------------------------------------------------------------------------------------------- [15:08:48] Vais Salikhov(@vais):@elia thanks, but this is exactly the place that's been driving me crazy - `read_escape` seems to be doing the right thing, but somehow, somewhere down the line this transformation occurs. `read_escape` definitely does not convert `\u0007` into `a` and `\u001b` into `e`... wtf.. ---------------------------------------------------------------------------------------------------- [15:10:27] Elia Schito(@elia):@vais that means it's after lexing and before parsing as the sexp already shows `\a` ---------------------------------------------------------------------------------------------------- [15:11:19] Vais Salikhov(@vais):Something is converting these unicode escapes into `\a` and `\e` which are not recognized by javascript, it just sees them as literal `a` and `e`. How to make them stay as unicode escapes all the way into js-land? ---------------------------------------------------------------------------------------------------- [15:11:59] Elia Schito(@elia):drop a `puts` :bomb: ---------------------------------------------------------------------------------------------------- [15:12:18] Elia Schito(@elia):but beware escaping: inspect vs. to_s ---------------------------------------------------------------------------------------------------- [15:23:09] Vais Salikhov(@vais):@elia I dropped so many `puts` bombs the whole thing looks like the surface of the moon :sweat: ---------------------------------------------------------------------------------------------------- [15:24:37] Vais Salikhov(@vais):Giving up for today. @elia if you or @adambeynon can take a look, plz lmk... It's not super urgent, just hate the feeling. ---------------------------------------------------------------------------------------------------- [15:26:35] Elia Schito(@elia):lol :) ---------------------------------------------------------------------------------------------------- [15:26:55] Elia Schito(@elia):quick attempt shows it's the lexer ---------------------------------------------------------------------------------------------------- [15:26:59] Elia Schito(@elia):``` >> l = Opal::Lexer.new('"\u0007"', 'file') => #, @scanner_stack=[#], @case_stmt=nil, @start_of_lambda=nil> >> l.next_token => [:tSTRING_BEG, ["\"", [1, 0]]] >> l.next_token => [:tSTRING_CONTENT, ["\a", [1, 1]]] >> l.next_token => [:tSTRING_END, ["\"", [1, 7]]] >> ``` ---------------------------------------------------------------------------------------------------- [15:27:43] Elia Schito(@elia):but also in ruby: ---------------------------------------------------------------------------------------------------- [15:27:50] Elia Schito(@elia):``` >> "\u0007" => "\a" ``` ---------------------------------------------------------------------------------------------------- [15:29:48] Elia Schito(@elia):@vais it's this line: https://github.com/opal/opal/blob/master/lib/opal/parser/lexer.rb#L262 ---------------------------------------------------------------------------------------------------- [15:30:06] Elia Schito(@elia):`scanner[1].to_i(16).chr(Encoding::UTF_8)` ---------------------------------------------------------------------------------------------------- [15:30:27] Elia Schito(@elia):converts to a hex num and then picks the corresponding char ---------------------------------------------------------------------------------------------------- [15:31:20] Vais Salikhov(@vais):@elia right, so then "\a" goes into js-land ---------------------------------------------------------------------------------------------------- [15:31:37] Vais Salikhov(@vais):But there it no longer has the same meaning ---------------------------------------------------------------------------------------------------- [15:33:21] Vais Salikhov(@vais):Ok, it's late here, my brain is fried. Thanks for the pointer, @elia, I'll pick it up tomorrow. :zzz: ---------------------------------------------------------------------------------------------------- [15:36:34] Elia Schito(@elia)::+1: ---------------------------------------------------------------------------------------------------- [20:29:54] Mitch VanDuyn(@catmando):anybody: using opal-rspec and playing with react.rb... this needs to include react.js... not sure how to add a include to the opal-rspec header that seems like its generated automatically by opal-rspec. Can anybody explain how I would go about including a js file so its there for all the specs to run? ---------------------------------------------------------------------------------------------------- [20:59:05] Forrest Chang(@fkchang):@catmando if react.js is in the load path you can just do a require 'react' ---------------------------------------------------------------------------------------------------- [21:04:14] Mitch VanDuyn(@catmando):problem is I am using gem react.rb which is also called "react" ---------------------------------------------------------------------------------------------------- [21:05:06] Mitch VanDuyn(@catmando):So I guess I need to pull down react.js save it in assets, rename it to something like react-js.js and then require 'react-js' will that work? ---------------------------------------------------------------------------------------------------- [21:27:25] Forrest Chang(@fkchang):@catmando there will be a problem if 2 files are compiled to react.js, maybe you can have a path that uniquely identifies it say, require 'vendor/assets/javascripts/react/react' or if you include an html file as your html for the test, you could do a script tag there ---------------------------------------------------------------------------------------------------- [21:35:05] Mitch VanDuyn(@catmando):@fkchang.. I guess. In this case its really a matter of new library (react.rb) that needs to under the hood include react.js... For now I took the route I suggested (rename react.js to react_js.js) and that works fine. ---------------------------------------------------------------------------------------------------- [21:37:00] Mitch VanDuyn(@catmando):@fkchang - please explain "or if you include an html file as your html for the test, you could do a script tag there" That was my original approach, but I could not figure out how to get opal-rspec to use a different index file. ---------------------------------------------------------------------------------------------------- [21:45:21] Elia Schito(@elia):@catmando @fkchang react.rb depends on react-source which is the gem from facebook itself ---------------------------------------------------------------------------------------------------- [21:45:28] Elia Schito(@elia):https://rubygems.org/gems/react-source ---------------------------------------------------------------------------------------------------- [21:47:03] Elia Schito(@elia):not sure with which path you can require it tho ---------------------------------------------------------------------------------------------------- [21:48:14] Mitch VanDuyn(@catmando):@elia, yeah I also could not figure that out... There is no doc for react-source. Also react.rb only requires react-source in development (!?) ---------------------------------------------------------------------------------------------------- [21:48:47] Elia Schito(@elia):and it doesn't work out of the box uh… ---------------------------------------------------------------------------------------------------- [21:50:05] Mitch VanDuyn(@catmando):I am guessing react-source would be required using 'react' but the name conflicts. I guess I could try renaming react.rb so that you can require react_rb or some such... ---------------------------------------------------------------------------------------------------- [21:51:53] Elia Schito(@elia):my gut tells me @zetachang has done his work properly and you don't need to ---------------------------------------------------------------------------------------------------- [21:52:58] Mitch VanDuyn(@catmando):could be, I am going to put in an issue, and perhaps he can clarify everything ---------------------------------------------------------------------------------------------------- [21:58:11] Forrest Chang(@fkchang):@catmando when you config the rake task for your opal specs you can configure the index file i.e. ```ruby Opal::RSpec::RakeTask.new("spec:opal") do |s| s.index_path = "opal/spec/index.html" ``` ---------------------------------------------------------------------------------------------------- [21:58:11] Forrest Chang(@fkchang): ---------------------------------------------------------------------------------------------------- [22:04:51] Mitch VanDuyn(@catmando):@fkchang... gotcha... thanks... ---------------------------------------------------------------------------------------------------- [22:47:14] Kurtis Rainbolt-Greene(@krainboltgreene):How should I handle data loading at compile time? ---------------------------------------------------------------------------------------------------- [22:56:32] Elia Schito(@elia):@krainboltgreene what do you mean? ---------------------------------------------------------------------------------------------------- [22:57:04] Kurtis Rainbolt-Greene(@krainboltgreene):@elia: I'm making a game, and I have configuration data stored as json files. ---------------------------------------------------------------------------------------------------- [22:57:17] Kurtis Rainbolt-Greene(@krainboltgreene):I want to load those files as native Ruby objects and have those available in runtime. ---------------------------------------------------------------------------------------------------- [22:58:04] Elia Schito(@elia):Like hashes or something else? ---------------------------------------------------------------------------------------------------- [23:02:06] Kurtis Rainbolt-Greene(@krainboltgreene):@elia: Sure. ---------------------------------------------------------------------------------------------------- ############################## [2015-05-07] ############################## [16:06:37] Vais Salikhov(@vais):@elia figured it out. The parser was doing everything right. To solve the problem of Ruby's `\a` and `\e` escape sequences not being supported in JS, I had to fix it in the compiler. That was the "next step" I was missing. The final result is here: https://github.com/opal/opal/pull/837 ---------------------------------------------------------------------------------------------------- [16:07:29] Vais Salikhov(@vais)::beer::beer::beer: ---------------------------------------------------------------------------------------------------- [16:17:27] Forrest Chang(@fkchang):I'm probably holding off on browser extensions indefinitely for the issues. Aside from not being able to show the value of the last evaluated object correctly if it's not a string or number, I do a have a working opal-irb chrome plugin. Is that of value to anyone? It's sort of like gdb/dbx/ where if you want to see the value you have to print it out out -- i.e. ``` p variable``` so it works. The in app opal-irb will be superior in that you don't have to do that, but the chrome panel is cool in that you can attach it to an opal app w/o having to build it in. ---------------------------------------------------------------------------------------------------- [16:18:16] Forrest Chang(@fkchang):Maybe I'll make a screencast and leave a question of "is this useful enough to release, given it can't do all the things I want?" ---------------------------------------------------------------------------------------------------- [16:30:41] Adam Beynon(@adambeynon):@fkchang I stopped working on an extension because of the same reasons ---------------------------------------------------------------------------------------------------- [16:30:49] Adam Beynon(@adambeynon):something like opal-irb seems the better option ---------------------------------------------------------------------------------------------------- ############################## [2015-05-08] ############################## [21:50:56] Elia Schito(@elia):it should ---------------------------------------------------------------------------------------------------- [21:51:06] Mitch VanDuyn(@catmando):trying now... ---------------------------------------------------------------------------------------------------- [21:51:56] Elia Schito(@elia)::+1: ---------------------------------------------------------------------------------------------------- [21:57:05] Brian Glusman(@bglusman):Just pushed up a tetris that runs in opal and on shoes locally FYI :-) bglusman/tetris ---------------------------------------------------------------------------------------------------- [21:58:33] Mitch VanDuyn(@catmando):@elia, yeah that works fine... bottom line (for me any way - add a config.js.rb.erb file and then include it the top level header. That works for dev and production. For running rspec in the browser I will just add the config to the spec helper. ---------------------------------------------------------------------------------------------------- [21:59:14] Mitch VanDuyn(@catmando):I'm thinking a little gem would be nice, or perhaps just add something to opal-rails ---------------------------------------------------------------------------------------------------- [21:59:20] Elia Schito(@elia):@bglusman awe ---------------------------------------------------------------------------------------------------- [22:00:18] Elia Schito(@elia):@bglusman just add a screenshot to the readme plz! ---------------------------------------------------------------------------------------------------- [22:00:59] Elia Schito(@elia):@catmando 0.8 should fix thise kind of issues ---------------------------------------------------------------------------------------------------- [22:01:58] Mitch VanDuyn(@catmando):@elia, not so much from an issue standpoint, but just would be nice to have a standard solution ---------------------------------------------------------------------------------------------------- [22:03:10] Elia Schito(@elia):sorry, I though the gem would have been to solve the require problem, plz be patient :smile_cat: ---------------------------------------------------------------------------------------------------- [22:05:28] Mitch VanDuyn(@catmando):no drama here at all, thanks for all the great work.. opal has been a life saver for us! ---------------------------------------------------------------------------------------------------- [22:13:10] Brian Glusman(@bglusman):@elia it's easy far from done, literally just pushed up the first version with Abby kind of proof it's at all functional :-) ---------------------------------------------------------------------------------------------------- [22:14:26] Elia Schito(@elia):@bglusman k, will wait, but think of the children! :D ---------------------------------------------------------------------------------------------------- [22:45:49] Vais Salikhov(@vais):@fkchang thanks for all the great work you've been doing to spread awareness of Opal. Just want you to know that it's made a huge difference. It will take time, but we're getting there. > I do need the feature thats somewhere deep down in @adambeynon 's todo list to be able to retrieve the code and comments to duplicate some of the small talk env stuff. Maybe @vais knows enough about the innards of Opal now that he could hit it I wish I did :) Is there an issue for this on GH? This would be the first step. I will be offline for a couple days, but will check back ;) ---------------------------------------------------------------------------------------------------- [14:58:01] AstonJ(@AstonJ):Agree with Rick - I think the Opal FAQ can be reworded at some point :) ---------------------------------------------------------------------------------------------------- [14:59:04] Rick Carlino(@RickCarlino):You might want to give it a second look. They have some great conversations on there, plus Reddit drives thousands of readers per week to my blog. It's a great place to share stuff that's useful to other developers. The key is to subscribe to good subreddits. ---------------------------------------------------------------------------------------------------- [14:59:39] Rick Carlino(@RickCarlino):The upvotes / downvotes stop people from being spammy, too. ---------------------------------------------------------------------------------------------------- [14:59:59] Vais Salikhov(@vais):@AstonJ what @RickCarlino said :+1: ---------------------------------------------------------------------------------------------------- [15:01:27] Rick Carlino(@RickCarlino):Also, "Reddit Enhancement Suite" is a pretty good user script if you're having trouble keeping track of stuff. Adds a ton of features as a browser plugin. ---------------------------------------------------------------------------------------------------- [15:04:40] AstonJ(@AstonJ):I think I posted about my Rails book idea on there a while back (or was it HN lol) - the responses were alright actually. It’s just that some of the threads I’ve seen on there seem indicate it is a ‘free for all’, which I find tedious. I will check out the Ruby bits tho. ---------------------------------------------------------------------------------------------------- [15:04:50] AstonJ(@AstonJ):Oo look… awwwww http://www.reddit.com/r/40DaysofRuby/comments/1tglws/for_those_of_you_preparing_to_start_ruby_i/ ---------------------------------------------------------------------------------------------------- [15:05:28] AstonJ(@AstonJ): ---------------------------------------------------------------------------------------------------- [15:06:04] Rick Carlino(@RickCarlino):**studio audience says "Awwww..."** ---------------------------------------------------------------------------------------------------- [15:06:33] Rick Carlino(@RickCarlino):https://www.reddit.com/domain/astonj.com ---------------------------------------------------------------------------------------------------- [15:07:26] AstonJ(@AstonJ):The one @dfyx posted has had the most comments (Red Hot Ruby article) :) ---------------------------------------------------------------------------------------------------- [15:08:28] AstonJ(@AstonJ):So this is the one to follow right? https://www.reddit.com/r/ruby/ ---------------------------------------------------------------------------------------------------- [15:09:53] AstonJ(@AstonJ):I am sure I had the ‘AstonJ’ user, but on trying to reset password it says no email with that username ---------------------------------------------------------------------------------------------------- [15:11:32] meh.(@meh):vais, yeah, I agree, but I also never read the FAQ :P ---------------------------------------------------------------------------------------------------- [15:24:37] AstonJ(@AstonJ):Something like this? @vais @RickCarlino @elia @meh @adambeynon ### Why does Opal exist? Opal exists because the power of Ruby in the browser is, and always has been, extremely appealing. Thanks to this power, Opal is now paving the way to allow developers to do what they could previously only dream off - isomorphic Ruby. ---------------------------------------------------------------------------------------------------- [15:26:26] AstonJ(@AstonJ):(Just initital thoughts - feel free to edit/modify) ---------------------------------------------------------------------------------------------------- [15:33:01] AstonJ(@AstonJ):Version 2: ### Why does Opal exist? Opal exists because the prospect of the power of Ruby in the browser was too good to ignore. Thanks to this power, Opal is now paving the way to allow developers to do what they could previously only dream off - client side apps in Ruby as well as full stack isomorphic Ruby. ---------------------------------------------------------------------------------------------------- [16:18:44] Michał Kalbarczyk(@fazibear):Hi, I’m messing around with new opal beta and source maps, and it looks like everything point to last line of ruby source ? Any clues why this thing happened ? Using sprockets 3.0 ? ---------------------------------------------------------------------------------------------------- [16:27:27] Michał Kalbarczyk(@fazibear):[![Screen Shot 2015-05-08 at 18.27.04.png](https://files.gitter.im/opal/opal/7CR1/thumb/Screen-Shot-2015-05-08-at-18.27.04.png)](https://files.gitter.im/opal/opal/7CR1/Screen-Shot-2015-05-08-at-18.27.04.png) ---------------------------------------------------------------------------------------------------- [16:41:10] Forrest Chang(@fkchang):@vais @RickCarlino @elia @meh @adambeynon @AstonJ On the note of spreading opal/explaining why rubyists should adopt Opal, I'm stumped. I thought my Rubyconf 13 video that brought @vais into the fold would've done it, I think I covered enough bases that a Rubyist would think it's a no brainer. Perhaps I showed too much info? Maybe I wasn't specific enough. I propose a bunch of Opal talks for conferences every year trying spread the message from various angles, to date only the Star Wars one was accepted. My Jubilee talk for Rubyconf 14 slips in Opal in the side door and I show that code, but that one also surprises me in how little attention Rubyists are paying to the "Ruby everywhere" thing that Jubilee and Opal give you. ---------------------------------------------------------------------------------------------------- [16:43:00] Forrest Chang(@fkchang):Some of it think needs concrete, pertinent examples. This Ruby-fying javascript series I'm blogging about is attempting to do that w/real world code. I've been assembling a pattern language around it that blogging is helping me solidify. I'm hoping give names to concrete things that explain why coding browser code in Opal really is much better can help. ---------------------------------------------------------------------------------------------------- [16:47:05] Forrest Chang(@fkchang):@all any help on having me flesh these out would be appreciated. If ppl can read, comment, discuss those things, that might help. I see how pattern languages yielded Design Patterns and all the descendant *** Patterns exploded by cataloging and naming things - I hope to enumerate the reasons starting w/my Ruby-fying JS. I'm trying to think about how to reword the messages, which I think are pretty darn solid for the Rubyist, in my various talk proposals. These days, they distill to why Ruby is better in the browser, and how Ruby everywhere is both viable and joyful. ---------------------------------------------------------------------------------------------------- [16:47:32] AstonJ(@AstonJ):You’re doing a great job @fkchang :+1: I think what Opal could really do with is some screencasts (or blogs) from the very basics up (bit like I am aiming to do with Volt :point_up: [May 8 2015 6:31 AM](https://gitter.im/AstonJ/rubyscreencasts?at=554c4a37489c98827952e2cb)). I am crap at JS so suggest someone with a better knowledge has a go instead of me. Ideally (at least in my mind) a series on Opal would show youhow to do stuff that you would usually use JS for without even mentioning JS. Almost like JS has been rendered superfluous. ---------------------------------------------------------------------------------------------------- [16:48:27] Forrest Chang(@fkchang):When I get around to building opal-inspector and the ilk, the message will be how opal will have better tooling/environment -- I've had that talk brewing for a while, I have the movie theme, quotes, multimedia all lined up for that. I do need the feature thats somewhere deep down in @adambeynon 's todo list to be able to retrieve the code and comments to duplicate some of the small talk env stuff. Maybe @vais knows enough about the innards of Opal now that he could hit it ---------------------------------------------------------------------------------------------------- [16:51:37] Forrest Chang(@fkchang):@AstonJ if you need my opal blogs http://funkworks.blogspot.com/search/label/opal - I had been meaning to collect all the various blogs at one point myself ---------------------------------------------------------------------------------------------------- [16:52:18] Rick Carlino(@RickCarlino):@fkchang I think it just takes time. My thought is that once Volt hits 1.0 and has proven itself in production it will be Opal's killer app. ---------------------------------------------------------------------------------------------------- [16:52:57] Rick Carlino(@RickCarlino):I heard about Opal for the first time maybe 18 months ago? When I heard about it I thought "Oh, cool. I'm going to star this and hope to god it grows an ecosystem" ---------------------------------------------------------------------------------------------------- [16:53:17] Rick Carlino(@RickCarlino):Im sure others who hear about Opal thinking the same thing- they're optimistic, but they need reassurance. ---------------------------------------------------------------------------------------------------- [16:55:26] Forrest Chang(@fkchang):@RickCarlino I think volt is definitely cool, but I feel Rails integration needs more pumping. When you can use Rails for all the good and many things it does well, and then Opal for the front end, that's huge for pretty much anyone who does rails. I tried to explain that in my Jubilee talk w/my demo app, where I summarized it as "Use rails to get me to the game, Jubilee/opal to play the game". Twitter signup oauth, like 3 lines in Rails, -- BAM, real time sync w/servers and players, a handful of Jubilee/opal code bam! ---------------------------------------------------------------------------------------------------- [16:55:38] AstonJ(@AstonJ):Sounds good Forrest. I do think we need to cover the basics first because that way we make it super easy for anyone to jump in - even benefits in the way of just helping with the mental shift. Agree with Rick too. Volt is going to be Opal’s first killer app, which in turn is going to get Opal a lot more interest. I sometimes think that Opal is actually going to be more of the heart/engine, of frameworks like Volt, Clearspring, Vienna, Fire etc. In some ways that is better for the Opal team as it’s less people asking support questions. ---------------------------------------------------------------------------------------------------- [16:55:43] Forrest Chang(@fkchang):Being able to leverage your old code and the entire Rails ecosystem isn't to be laughed at ---------------------------------------------------------------------------------------------------- [16:56:08] AstonJ(@AstonJ):Also agree with you about Rails integration Forrest. ---------------------------------------------------------------------------------------------------- [16:56:16] Forrest Chang(@fkchang):We deployed our 1st production rails app w/opal last night. Opal was a huge part of the success ---------------------------------------------------------------------------------------------------- [16:56:21] AstonJ(@AstonJ):(I’m off shopping now but will catch up later) ---------------------------------------------------------------------------------------------------- [16:56:32] Rick Carlino(@RickCarlino):That's true- maybe I'll write an article titled "How to get Opal in your existing Rails app today" ---------------------------------------------------------------------------------------------------- [16:56:44] Rick Carlino(@RickCarlino):We can see how people take to it. ---------------------------------------------------------------------------------------------------- [16:56:46] Forrest Chang(@fkchang):I think Rails ppl need to see and hear this. The problem is none of the production rails app are open source ---------------------------------------------------------------------------------------------------- [16:57:55] Rick Carlino(@RickCarlino):I work on two production Rails apps that are opensource. I can try to wedge it in where possible ---------------------------------------------------------------------------------------------------- [16:58:03] Rick Carlino(@RickCarlino):although, both use angular :( ---------------------------------------------------------------------------------------------------- [16:58:05] Forrest Chang(@fkchang):I'll get down to blogging about various techniques I've come up with that I think are pretty nice. It'd be nice if we could get a little blog circle on that. @adambeynon and @elia would have probably the most data on that ---------------------------------------------------------------------------------------------------- [16:59:09] Rick Carlino(@RickCarlino):Doesn't "The Opalist" cover this sort of stuff currently? Who runs that? ---------------------------------------------------------------------------------------------------- [16:59:12] Forrest Chang(@fkchang):I'd be curious what @jaredcwhite is working on. Kudos again on the opalist. I think that will help w/the cause. It has me committing to providing content for each issue which I think is a good thing. Sometimes we just need deadlines to get stuff to the top fo the q ---------------------------------------------------------------------------------------------------- [17:01:26] Forrest Chang(@fkchang):On another thing, a message I know most ppl don't grok is that I think "Ruby web components" has the potential to be significant -- matching w/all the other web components (official and implemented by various frameworks) buzz that I also realize most ppl don't grok. It's why I really like @meh 's lissio ---------------------------------------------------------------------------------------------------- [17:02:18] Forrest Chang(@fkchang):React has been strong in pushing the reasons why lissio is really significant, but lissio's implementation is better, IMO, it's all objects, all Ruby, cohesively together ---------------------------------------------------------------------------------------------------- [17:02:26] Forrest Chang(@fkchang):at the point, coding is just Ruby ---------------------------------------------------------------------------------------------------- [17:02:31] Forrest Chang(@fkchang):and that is significant ---------------------------------------------------------------------------------------------------- [17:07:26] Jared White(@jaredcwhite):@RickCarlino @fkchang Opalist is a bi-weekly email newsletter. I also have a matching blog, which I'm obviously happy to open up to anyone who would like to publish on that, although I suspect most people writing a blog post will want to post on their own blog. (Which is fine, I can link to that from the newsletter!) So...I'm checking Reddit, Ruby news sites, etc. like anybody, but if you specifically want to make sure your content ends up in Opalist just send it my way. hello@whitefusion.io ---------------------------------------------------------------------------------------------------- [17:20:49] Rick Carlino(@RickCarlino):Good stuff. Would probably be good if it had a "Submit an article" form or something. I'll have some content here shortly. ---------------------------------------------------------------------------------------------------- [18:53:42] Elia Schito(@elia):> I think it just takes time. I agree, if anyone remember how Ruby & Rails were considered in the early years… ---------------------------------------------------------------------------------------------------- [18:55:05] Elia Schito(@elia):> We deployed our 1st production rails app w/opal last night. @fkchang that would be cool to list on the site, that too in the early years helped rails ---------------------------------------------------------------------------------------------------- [18:55:59] Elia Schito(@elia):@fkchang also I think that would be cool if you were blogging from the opalrb.org blog, at least for general stuff ---------------------------------------------------------------------------------------------------- [19:13:31] Elia Schito(@elia):@jaredcwhite how many days left before the next opalist issue? ---------------------------------------------------------------------------------------------------- [19:13:47] Rick Carlino(@RickCarlino):Great question. ---------------------------------------------------------------------------------------------------- [19:13:55] Rick Carlino(@RickCarlino):@RickCarlino wants to know how long he can procrastinate ---------------------------------------------------------------------------------------------------- [19:14:09] Elia Schito(@elia):haha, meee too ---------------------------------------------------------------------------------------------------- [19:14:20] Elia Schito(@elia):was thinking it would be nice to have the 0.8 post out for that date ---------------------------------------------------------------------------------------------------- [19:28:14] Rick Carlino(@RickCarlino):Oh lol @edubkendo is in here. Long time no see, sir. ---------------------------------------------------------------------------------------------------- [19:28:28] Rick Carlino(@RickCarlino):We met many moons ago in the TowerJS days ---------------------------------------------------------------------------------------------------- [19:34:22] Jared White(@jaredcwhite):@RickCarlino Great point, I will work on that. @elia Next issue's going out Wednesday next week (May 13). I will try to get you a PR for a link as well. :shipit: ---------------------------------------------------------------------------------------------------- [19:38:44] Elia Schito(@elia):ok, then I don't think I'll be able to write something :( ---------------------------------------------------------------------------------------------------- [19:38:52] Elia Schito(@elia):great to hear about that PR ---------------------------------------------------------------------------------------------------- [19:40:01] Elia Schito(@elia):If you guys have any production app with opal installer would be also great to have a "trysted by" section in the homepage ---------------------------------------------------------------------------------------------------- [20:10:02] AstonJ(@AstonJ):@jaredcwhite Do you think you could update the Opal site with a list of all Opal related articles to date too? :point_up: [May 8 2015 12:38 PM](https://gitter.im/opal/opal?at=554ca024629c609946251102) Seems more sense for you to do it if you are already scouring the web for Opal-related stuff :) If you can’t no worries, but could you email us a list of Opal-related articles you know of to date please? One of us can add them to the site then. ---------------------------------------------------------------------------------------------------- [20:12:39] Elia Schito(@elia):@AstonJ @jaredcwhite opening now an issue on opalrb.org to gather the list so you too can accumulate stuff there and get an agreement on where it's better to put them in the site :smiley: ---------------------------------------------------------------------------------------------------- [20:13:05] AstonJ(@AstonJ):Awesome, thanks @elia :) ---------------------------------------------------------------------------------------------------- [20:14:13] Elia Schito(@elia):https://github.com/opal/opalrb.org/issues/19 ---------------------------------------------------------------------------------------------------- [21:10:45] Mitch VanDuyn(@catmando):anybody have strategies for configuring opal between development/test/production. ---------------------------------------------------------------------------------------------------- [21:11:31] Mitch VanDuyn(@catmando):For example i have a string value that I need to have a different value depending on whether we are in test/development or production. ---------------------------------------------------------------------------------------------------- [21:12:06] Rick Carlino(@RickCarlino):Is ERB an option? ---------------------------------------------------------------------------------------------------- [21:12:55] Rick Carlino(@RickCarlino):Oh wait, I'm not sure that would work. It might in the asset pipeline, though. Have you tried adding a .erb to the end and putting in some ERB with an ENV[] var? ---------------------------------------------------------------------------------------------------- [21:13:26] Adam Beynon(@adambeynon):yep, I use the erb solution (with asset pipeline) ---------------------------------------------------------------------------------------------------- [21:14:03] Rick Carlino(@RickCarlino):Ah, but you don't like it I take it? ---------------------------------------------------------------------------------------------------- [21:14:29] Rick Carlino(@RickCarlino):Probably makes it hard for your syntax highlight to do its job ---------------------------------------------------------------------------------------------------- [21:14:30] Elia Schito(@elia):I tend to prefer data attributes, in some cases I used meta tags and loaded into ENV (inside opal) ---------------------------------------------------------------------------------------------------- [21:15:01] Adam Beynon(@adambeynon):umm, its not ideal. I keep meaning to move to something similar to elia ^^ ---------------------------------------------------------------------------------------------------- [21:30:58] Mitch VanDuyn(@catmando):soo not be a dummy but... I stuck a little file (config.js.rb.erb) into the assets folder. ---------------------------------------------------------------------------------------------------- [21:31:29] Mitch VanDuyn(@catmando):I can require it fine in the opal code, but the erb is not getting expanded ---------------------------------------------------------------------------------------------------- [21:31:49] Mitch VanDuyn(@catmando):do I have to do something to enable this in the asset pipeline? ---------------------------------------------------------------------------------------------------- [21:31:49] Elia Schito(@elia):v0.7? ---------------------------------------------------------------------------------------------------- [21:32:20] Mitch VanDuyn(@catmando):yeah more or less (its my patched version mostly 0.7) ---------------------------------------------------------------------------------------------------- [21:32:55] Elia Schito(@elia):then you either use master or you use the .erb as main file ---------------------------------------------------------------------------------------------------- [21:33:10] Elia Schito(@elia):in 0.7 only the main file gets full sprockets treatment ---------------------------------------------------------------------------------------------------- [21:34:14] Elia Schito(@elia):0.8 restores full sprockets processing while keeping support for require order ---------------------------------------------------------------------------------------------------- [21:37:27] Mitch VanDuyn(@catmando):the main file being like application.js.rb ? ---------------------------------------------------------------------------------------------------- [21:37:45] Elia Schito(@elia):yep, would be application.js.rb.erb ---------------------------------------------------------------------------------------------------- [21:37:49] Elia Schito(@elia):that should work ---------------------------------------------------------------------------------------------------- [21:43:55] Mitch VanDuyn(@catmando):nope :-( ---------------------------------------------------------------------------------------------------- [21:44:20] Mitch VanDuyn(@catmando):but ... ---------------------------------------------------------------------------------------------------- [21:44:37] Elia Schito(@elia):that is the file you use for javascript_include_tag? ---------------------------------------------------------------------------------------------------- [21:44:45] Elia Schito(@elia):_assuming rails_ ---------------------------------------------------------------------------------------------------- [21:44:55] Mitch VanDuyn(@catmando):what exactly do we mean by top level file... ---------------------------------------------------------------------------------------------------- [21:45:03] Mitch VanDuyn(@catmando):what if you have multiple? ---------------------------------------------------------------------------------------------------- [21:45:15] Elia Schito(@elia):example? ---------------------------------------------------------------------------------------------------- [21:45:34] Mitch VanDuyn(@catmando):we have a ton of javascript_include_tags ---------------------------------------------------------------------------------------------------- [21:45:43] Elia Schito(@elia):shouldn't be a problem ---------------------------------------------------------------------------------------------------- [21:45:43] Mitch VanDuyn(@catmando):our asset pipeline structure is a mess ---------------------------------------------------------------------------------------------------- [21:46:09] Mitch VanDuyn(@catmando):so as long as its being pulled in via the top level javascript_include_tag it should work ---------------------------------------------------------------------------------------------------- [21:46:11] Elia Schito(@elia):does it work you use erb on a plain js file? ---------------------------------------------------------------------------------------------------- [21:46:19] Elia Schito(@elia):yep ---------------------------------------------------------------------------------------------------- [21:50:40] Mitch VanDuyn(@catmando):so as long as I directly include config.js.rb.erb all should be well correct? ---------------------------------------------------------------------------------------------------- [02:40:01] Kurtis Rainbolt-Greene(@krainboltgreene):@elia Hey, re: our previous discussion about other filesystem operations it seems like Opal's File and Dir classes already assume some level of "during build process"? ---------------------------------------------------------------------------------------------------- [02:40:58] Kurtis Rainbolt-Greene(@krainboltgreene):Or they talk to a virtual fs, I can't really tell. ---------------------------------------------------------------------------------------------------- [02:49:05] Kurtis Rainbolt-Greene(@krainboltgreene):Ugh, this is really just becoming an annoying blocker for me. Hmm. ---------------------------------------------------------------------------------------------------- [04:12:36] Kurtis Rainbolt-Greene(@krainboltgreene):@elia: http://opalrb.org/try/?code:hash%20%3D%20%7B%20foo%3A%201%20%7D%0Astring%20%3D%20%22Value%3A%20%25%3Cfoo%3E%22%0A%0Aputs(string%20%25%20hash) :( ---------------------------------------------------------------------------------------------------- [07:52:09] Elia Schito(@elia):@krainboltgreene fixed on master, but with {} instead of <> ---------------------------------------------------------------------------------------------------- [07:52:19] Elia Schito(@elia):thanks to @vais of course ---------------------------------------------------------------------------------------------------- [08:07:23] Elia Schito(@elia):@adambeynon ping, got my message? ---------------------------------------------------------------------------------------------------- [09:51:33] Vais Salikhov(@vais):@elia @krainboltgreene actually both `%{}` and `%<>` format strings are fully supported now. `Kernel#format` (and the many names it's known by and the many forms in which it manifests itself) is 100% rubyspec-compliant since https://github.com/opal/opal/commit/511565ab80b1ae2250ef29d99ba6f6ec18a3558e :beers: ---------------------------------------------------------------------------------------------------- [09:52:12] Elia Schito(@elia):uh, maybe I did something wrong when I tried it ---------------------------------------------------------------------------------------------------- [09:53:42] Elia Schito(@elia):@vais I get `ArgumentError: malformed format string - %` when executing the code from @krainboltgreene's link ---------------------------------------------------------------------------------------------------- [09:53:55] Elia Schito(@elia):``` hash = { foo: 1 } string = "Value: %" puts(string % hash) ``` ---------------------------------------------------------------------------------------------------- [10:00:16] Vais Salikhov(@vais):@elia I see - this must be a case not covered by rubyspec then. This is actually a pretty little-known feature of ruby for some reason. The difference between `%{}` and `%<>` is that the first one is not followed by a field specifier, but the second one must be, otherwise it does not work. So, in MRI it fails silently, but in Opal it blows up, as it should :) Check this out: ``` $ ruby -v -e "p('Value: %' % { foo: 1 })" ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-darwin14] "Value: %" $ ruby -v -e "p('Value: %s' % { foo: 1 })" ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-darwin14] "Value: 1" $ bundle exec opal -v -e "p('Value: %s' % { foo: 1 })" Opal v0.8.0.dev "Value: 1" ``` ---------------------------------------------------------------------------------------------------- [10:02:28] Vais Salikhov(@vais):MRI's behavior above should be considered a bug, since it silently drops the value on the floor instead of complaining about an invalid format string. This is how *we* roll: ``` $ bundle exec opal -v -e "p('Value: %' % { foo: 1 })" Opal v0.8.0.dev /private/var/folders/pt/kr0lwm4d20jgc_jvpc5fyk1r0000gn/T/opal-nodejs-runner-20150508-18639-1wd0fyb:3603 throw exception; ^ ArgumentError: malformed format string - % ``` ---------------------------------------------------------------------------------------------------- [10:18:28] Elia Schito(@elia):go @vais! in which Opal uncovered an MRI bug :P ---------------------------------------------------------------------------------------------------- [10:29:59] Vais Salikhov(@vais):@elia LOL. I just checked on 2.0.0 cause I though this may be a regression in 2.2.0, but no, it's the same. Go figure. Well, @brixen did complain about MRI devs not using rubyspec :trollface: Except that there is no test covering this particular case in rubyspec either double-:trollface: ri Kernel#sprintf just has this to say at the very bottom: ``` For more complex formatting, Ruby supports a reference by name. %s style uses format style, but %{name} style doesn't. Examples: sprintf("%d : %f", { :foo => 1, :bar => 2 }) #=> 1 : 2.000000 sprintf("%{foo}f", { :foo => 1 }) # => "1f" ``` ---------------------------------------------------------------------------------------------------- [10:31:33] Elia Schito(@elia):@vais should be noted that now they're actually using it https://github.com/ruby/rubyspec ---------------------------------------------------------------------------------------------------- [10:31:50] Vais Salikhov(@vais):It's officially my favorite feature of Ruby :stuck_out_tongue_closed_eyes: ---------------------------------------------------------------------------------------------------- [10:32:12] Vais Salikhov(@vais)::stuck_out_tongue_winking_eye: ---------------------------------------------------------------------------------------------------- [10:32:23] Elia Schito(@elia)::smile_cat: ---------------------------------------------------------------------------------------------------- [10:36:55] Vais Salikhov(@vais):@elia my git-fu is still not strong enough to sync our outdated rubyspec fork with theirs :sweat_smile: ---------------------------------------------------------------------------------------------------- [10:37:35] Elia Schito(@elia):I still dream up on doing it myself, but I lack time-fu :clock230: ---------------------------------------------------------------------------------------------------- [10:38:16] Elia Schito(@elia):last time I think mike did the hard work ---------------------------------------------------------------------------------------------------- [10:38:55] Elia Schito(@elia):https://github.com/opal/opal/pull/528 ---------------------------------------------------------------------------------------------------- [10:54:15] Vais Salikhov(@vais):@elia the way I think about it is we still have plenty of failing cases to work on as it is, so no rush :) ---------------------------------------------------------------------------------------------------- [11:17:56] Elia Schito(@elia):@/all beta1 is out! https://rubygems.org/gems/opal/versions/0.8.0.beta1 ---------------------------------------------------------------------------------------------------- [11:22:20] Elia Schito(@elia):(ugh https://travis-ci.org/opal/opal/jobs/61749537, fixed on master) ---------------------------------------------------------------------------------------------------- [11:25:42] AstonJ(@AstonJ):Nice one @elia :+1: ---------------------------------------------------------------------------------------------------- [11:26:02] Elia Schito(@elia)::smile: ---------------------------------------------------------------------------------------------------- [11:28:00] Vais Salikhov(@vais):Where in the world is @mieko?

I think Opal deserves more attention on /r/ruby. Right now the burden is on us to give the community something worth talking about. BTW @elia @adambeynon the *"try and keep ruby relevant"* always rubbed me the wrong way. Does anyone else feel that way? ---------------------------------------------------------------------------------------------------- [14:55:06] Rick Carlino(@RickCarlino):@vais Just so I make myself apparent- I think the high volume of Opal posts on /r/ruby is **a good thing**. ---------------------------------------------------------------------------------------------------- [14:55:57] Vais Salikhov(@vais):@RickCarlino no, I understood you correctly :) Just offering an explanation as to why. ---------------------------------------------------------------------------------------------------- [14:56:13] Rick Carlino(@RickCarlino):But yeah "try and keep Ruby relevant" might indicate that its losing relevance to some people ---------------------------------------------------------------------------------------------------- [14:56:32] Rick Carlino(@RickCarlino):Maybe "spread the power of Ruby to new platforms" ---------------------------------------------------------------------------------------------------- [14:57:25] AstonJ(@AstonJ):Is r/ruby, reddit? I have never seen the appeal tbh - it just looks like a stripped down forum but where it’s really difficult to keep track of the conversation. ---------------------------------------------------------------------------------------------------- ############################## [2015-05-09] ############################## [03:10:38] Rick Carlino(@RickCarlino):@bglusman That's awesome. Way to target the benefits of isomorphism. Blog about it! The world needs to know! ---------------------------------------------------------------------------------------------------- [13:14:40] Kurtis Rainbolt-Greene(@krainboltgreene):@elia @vais: Wow, thanks for that fix. I'll pull from master later today. ---------------------------------------------------------------------------------------------------- [17:43:55] AstonJ(@AstonJ):Nice! Looking forward to seeing rubytetris.com and all of our scores @bglusman ;-) ---------------------------------------------------------------------------------------------------- [23:08:05] Jamie Gaskins(@jgaskins):@AstonJ Sorry, I only just saw your message about screencasts. For some reason, I didn't get the email from Gitter about the mention. I'd love to get in on that. I was thinking of making some Clearwater screencasts anyway. :+1: ---------------------------------------------------------------------------------------------------- ############################## [2015-05-10] ############################## [00:07:45] AstonJ(@AstonJ):@jgaskins No probs Jamie I’ll add you to the room :-) We’re currently debating on the direction - whether we go for a screencasting outfit (which I think may be fraught with problems or take too much time to set up properly) or a syndicate style app that feeds everyone’s videos through Rubycasters.com, giving everyone independence and freedom to follow their own vision. Have a read of my post starting ‘Attention please’. ---------------------------------------------------------------------------------------------------- [03:23:01] Mario Rogic(@supermario):Hey guys - I've been messing with Opal for a while now, including presenting it at a Ruby Meetup in Melbourne recently where it was pretty well received (demoed a WIP game and a FirefoxOS weather app). I'm really struggling from time to time however, mostly with `opal-browser` not having docs, using specs as docs but them not working somehow (i.e. can't for the life of me get `Interval` to work, or `Browser::Console`, but then others like `Browser::HTTP` are fine). I'm not sure if perhaps I'm missing something - but I'd love to figure it all out and even contribute back with docs. Can someone help, or point me in the right direction? ---------------------------------------------------------------------------------------------------- [03:49:31] Jamie Gaskins(@jgaskins):@supermario Did you `require 'browser/interval'`? That one's necessary to require manually, same with `require 'browser/delay'`. Also, I've been using the GitHub version of `opal-browser` in my apps because I think the current gem release is pretty far behind it. ---------------------------------------------------------------------------------------------------- [03:50:29] Jamie Gaskins(@jgaskins):@supermario Also, the code itself is _very_ well written and documented, so you should be able to find your way through it reasonably well. Some stuff in the gem, I'd really like docs for, so maybe I'll put in a PR for it when I get some free time. ---------------------------------------------------------------------------------------------------- [11:19:26] Mario Rogic(@supermario):@jgaskins I was positive I had – but just tried again and now fine, so I must have made some mistake. Yep, I'm pulling straight from github in my gemfile. ---------------------------------------------------------------------------------------------------- [11:21:25] Mario Rogic(@supermario):Not trying to imply the code is poorly written or documented, just sharing I'm having a tough time as a professional developer (not ruling out it could just be that I'm daft), and wonder if beginners would fare much worse. If I can help that cause, I'd be happy to. ---------------------------------------------------------------------------------------------------- [11:23:05] Mario Rogic(@supermario):I guess i'll crack on some more, and keep watching issues to see if there's some area I can help out :smile: ---------------------------------------------------------------------------------------------------- [17:29:12] Forrest Chang(@fkchang):@supermario I've been wanting to write docs/a series of blog posts on opal-browser primarily because I feel nearly no one knows about it, and they end up reimplementing it when they don't need to. Also, someone needs to pimp @meh 's work ---------------------------------------------------------------------------------------------------- [17:30:40] Forrest Chang(@fkchang):Though lately I haven't been using it much because it conflicts w/opal-jquery in places and the bulk of the opal I've been doing uses rails - I put both opal-browser and opal-jquery on an internal project, but for our app that just went to production on thurs, I decided not to fight the fact that rails comes w/jquery and our app already uses it. Some team members tried to pull it in, hit some issues and backed out ---------------------------------------------------------------------------------------------------- [17:33:32] meh.(@meh):fkchang, I could try to work around those if you know what was up ---------------------------------------------------------------------------------------------------- [17:33:42] meh.(@meh):they should not conflict ---------------------------------------------------------------------------------------------------- [18:01:58] Forrest Chang(@fkchang):@meh I need to catalog what the problems were, I think 1 was that both set $document. I can ask the team if they remember what the problems they hit were. For the internal tool, I think the order I evaluated mattered depending on what it was that I wanted to do ---------------------------------------------------------------------------------------------------- [23:50:07] Mario Rogic(@supermario):I'm finding less and less of a need for jQuery lately, especially with different approaches like React. Also http://youmightnotneedjquery.com/ – so yeah I'd agree, I didn't find opal-browser for a while and even then had issues until I went straight from GH repo. Would definitely be a stumbling block for beginners I think! ---------------------------------------------------------------------------------------------------- ############################## [2015-05-11] ############################## [16:27:30] Rick Carlino(@RickCarlino):Is `opal-rails` set to have source maps by default? ---------------------------------------------------------------------------------------------------- [16:28:13] Rick Carlino(@RickCarlino):It says it does, but I'm not seeing them. It appears that I have source maps enabled in Chrome and have assets in debug mode ---------------------------------------------------------------------------------------------------- [16:30:22] Rick Carlino(@RickCarlino):It maps to `the_correct_file.rb` in console, but when I open that file, it's compiled output, not Ruby ---------------------------------------------------------------------------------------------------- [16:36:17] Elia Schito(@elia):@RickCarlino I need to check how other projects set defaults for different environments ---------------------------------------------------------------------------------------------------- [16:37:00] Rick Carlino(@RickCarlino):Ah ok. So its a known issue with `opal-rails`? ---------------------------------------------------------------------------------------------------- [16:37:47] Elia Schito(@elia):no, it should work afaik, was just pointing out that current status is a bit fragile ---------------------------------------------------------------------------------------------------- [16:50:19] Forrest Chang(@fkchang):@RickCarlino which version of opal r u using? source maps are (were?) broken for the 0.7.* I've been using lately ---------------------------------------------------------------------------------------------------- [16:50:34] Forrest Chang(@fkchang):on 0.6.* they worked out of the box for me ---------------------------------------------------------------------------------------------------- [16:50:40] Elia Schito(@elia):@fkchang thanks, that's the right question ---------------------------------------------------------------------------------------------------- [16:51:36] Rick Carlino(@RickCarlino):``` opal (0.7.1) hike (~> 1.2) sourcemap (~> 0.1.0) sprockets (>= 2.2.3, < 4.0.0) tilt (~> 1.4) opal-activesupport (0.1.0) opal (>= 0.5.0, < 1.0.0) opal-jquery (0.3.0) opal (~> 0.7.0) opal-rails (0.7.0) jquery-rails opal (~> 0.7.0) opal-activesupport (>= 0.0.5) opal-jquery (~> 0.3.0.beta1) opal-rspec (~> 0.4.0) rails (>= 3.2, < 5.0) opal-rspec (0.4.2) opal (~> 0.7.0) ``` ---------------------------------------------------------------------------------------------------- [16:51:47] Rick Carlino(@RickCarlino):Yep.

What's the exact cut off hour? ---------------------------------------------------------------------------------------------------- [20:50:39] Jared White(@jaredcwhite):@AstonJ Yep, will add some stuff here https://github.com/opal/opalrb.org/issues/19 @fkchang When I go to bed on Tuesday. :) Generally around 10:30pm ---------------------------------------------------------------------------------------------------- [22:05:32] Rick Carlino(@RickCarlino):Is try opal broke right now? ---------------------------------------------------------------------------------------------------- [22:05:49] Elia Schito(@elia):just pushed a new version of opalrb ---------------------------------------------------------------------------------------------------- [22:06:02] Rick Carlino(@RickCarlino):Ah- just temporary? ---------------------------------------------------------------------------------------------------- [22:06:21] Elia Schito(@elia):no, was supposedly ok, let me check, what's the error? ---------------------------------------------------------------------------------------------------- [22:06:44] Rick Carlino(@RickCarlino):http://opalrb.org/try/ <-- broke in chrome on linux ---------------------------------------------------------------------------------------------------- [22:19:55] Elia Schito(@elia):@RickCarlino should be fixed ---------------------------------------------------------------------------------------------------- [22:20:19] Elia Schito(@elia):let me know if you see any other broken stuff ---------------------------------------------------------------------------------------------------- ############################## [2015-05-12] ############################## [04:19:43] Forrest Chang(@fkchang):Pre- react, I think most people just wouldn't grok lissio, after lissio, I think it makes sense. That everything including CSS is in Opal is a distinguishing aspect of lissio ---------------------------------------------------------------------------------------------------- [08:12:49] Vais Salikhov(@vais):@fkchang re #840, I must admit you are over-estimating my current ability with Opal by an order of magnitude or two :sweat_smile: Nevertheless, having it posted as an issue gives it visibility and a chance of getting worked on. Who knows, maybe even by yours truly... ---------------------------------------------------------------------------------------------------- [08:28:20] Elia Schito(@elia):@catmando i'd love to help but I'm a bit tight with time, there's already an issue open on opal or opal-rails or opal-rspec? ---------------------------------------------------------------------------------------------------- [14:28:44] Mitch VanDuyn(@catmando):@elia - no drama. If there is not an obvious answer, then I will indeed open an issue on opal-rspec. I think the root problem is that opal-rpsec should build one tree of requires for the entire test, not a separate tree for each individual test spec. I might fork a branch and see if I can get that work. In the mean time I put a work around in place: I made a version of react.js that checks if its loaded. I am just loading that version in test (not in production or development.) That got me through the night. I will add that to the notes on the problem in case anybody else bumps into this. ---------------------------------------------------------------------------------------------------- [15:16:33] Jared White(@jaredcwhite):Anyone try getting the latest Opal 0.8.0.beta1 and opal-rails working? I'm just not having luck at all. https://github.com/opal/opal-rails/issues/49#issuecomment-101317128 ---------------------------------------------------------------------------------------------------- [15:32:47] Forrest Chang(@fkchang):@vais re: #840 -- maybe, I figure it's just a matter of time. When @meh is directing issues directly to you, I figure u picked up very quickly ---------------------------------------------------------------------------------------------------- [15:57:00] Vais Salikhov(@vais):Thanks @fkchang I'm seriously flattered :blush: ---------------------------------------------------------------------------------------------------- [15:57:32] meh.(@meh):vais, did anyone give you the contributor bit yet? you should get it if not ---------------------------------------------------------------------------------------------------- [16:08:19] Vais Salikhov(@vais):@meh yes! I'm a "collaborator" :smile: I still prefer to send PRs though :sweat_smile: ---------------------------------------------------------------------------------------------------- [16:16:23] Forrest Chang(@fkchang):@vais ur welcome. I'm just going to keep flattering u until the feature is in ;) ---------------------------------------------------------------------------------------------------- [16:17:02] meh.(@meh):lol ---------------------------------------------------------------------------------------------------- [16:19:22] Forrest Chang(@fkchang):Related to opal promotion and killer apps, I'd like to think that if I build out opal inspector w/it's smalltalk and lisp machine inspired features, that could be a killer app for Opal. avdi has been posting about smalltalk, and I completely could build in a lot of those things he's excited about. ---------------------------------------------------------------------------------------------------- [16:19:45] Forrest Chang(@fkchang):like this https://twitter.com/avdi/status/597423163509764096 I could completely build that (somewhat simulated because we don't exactly have the full smalltalk features) ---------------------------------------------------------------------------------------------------- [16:20:10] Forrest Chang(@fkchang):I'm tempted to build it and then basically post the same thing but with #opal ---------------------------------------------------------------------------------------------------- [16:27:27] Vais Salikhov(@vais):@fkchang how about that "find by example" feature? (Finds what method could be used to accomplish the output based on input). I can't wrap my mind around how that's even implemented in Smalltalk. Mind-blowing. ---------------------------------------------------------------------------------------------------- [16:27:56] Vais Salikhov(@vais):BTW, here's the video http://devblog.avdi.org/2015/05/11/in-which-i-make-you-hate-ruby-in-7-minutes/ ---------------------------------------------------------------------------------------------------- [16:35:21] Forrest Chang(@fkchang):@vais actually find by example is already implemented as a gem https://github.com/BMorearty/what_methods --- the way it's done is a little more complicated than I would've done it (probably covers more edge cases and it blacklists certain dangerous methods). Unfortunately that code didn't work when I pasted it into opal-irb, so I'll end up rewriting it anyways ---------------------------------------------------------------------------------------------------- [16:36:52] Forrest Chang(@fkchang):the 7 min demo, I could come reasonably close to duplicating. Being able to lookup code/comments would be a key part of approximating/duplicating the smalltalk experience ---------------------------------------------------------------------------------------------------- [16:37:37] Forrest Chang(@fkchang):On a side note, I thought I would name opal-inspector - clouseau, but unfortunately that name is taken. I have all sorts of Pink Panther imagery for my eventual talk on it ---------------------------------------------------------------------------------------------------- [16:38:19] Forrest Chang(@fkchang):though a video called "in which I make you love Opal in 7 minutes" would be cool ---------------------------------------------------------------------------------------------------- [16:44:02] Forrest Chang(@fkchang):@AstonJ @elia @meh @adambeynon @vais I think this excerpt from this Rust critique applies to opal http://www.viva64.com/en/b/0324/ i.e. ```I think it's high time we started learning lessons of history. No one sane will ever start using a new language in their projects until you show them a few cool development tools supporting it, tell them a couple of success stories, and show a dozen of programmers working with that language and living close by. As for programmers, they will never - except probably for the youngest ones - spend their time and health on learning another "very best" language until you show them a few cool development tools (not a frob like Racer) and a couple of tens of thousands of ready-made libraries (not "experimental" or "unstable" or stuff like that), tell them a couple of success stories, and show them a dozen of open vacancies in their city or town. You know, it's like the "Chicken or the Egg" dilemma. On very rare occasions, this problem does get resolved (relatively representative examples are Go and Scala) - mostly thanks to investments of time and money from some large company (Google, Typesafe) who for some reason finds it worthy to popularize a new language.``` ---------------------------------------------------------------------------------------------------- [17:20:33] AstonJ(@AstonJ):Completely agree with that Forrest :+1: I think Volt will be Opal's first killer app and when Volt gets its own killer app, Opal will benefit hugely as well. I also agree about showing people stuff, how they can use it (and why it's so much better than the alternatives!!) ...exactly why I think good quality screencasts are important. I'm currently reformatting my Mac but will post a summary of what's going on with the screencasts and where everyone's at later this week :) ---------------------------------------------------------------------------------------------------- [19:01:29] Dan Ross(@btnpushnmunky):Hi there. I have the following code to get a file input tag `file_input = Element.find("#fileInput")`. I'm using opal-jquery as well as just opal. I can't figure out a way to get the file being uploaded.

Any help would be appreciated. ---------------------------------------------------------------------------------------------------- [21:45:33] Forrest Chang(@fkchang):@jaredcwhite submitted post via submit-link --- 7.5 hours before the deadline! ---------------------------------------------------------------------------------------------------- [21:45:58] Rick Carlino(@RickCarlino):. #livingOnTheEdge #YOLO ---------------------------------------------------------------------------------------------------- [23:16:15] Rick Carlino(@RickCarlino):Has anyone dealt with class level instance var issues in Opal before? ---------------------------------------------------------------------------------------------------- [23:16:22] Rick Carlino(@RickCarlino):https://github.com/opal/opal/issues/849 ---------------------------------------------------------------------------------------------------- [23:39:51] Jared White(@jaredcwhite):@RickCarlino Replied -- it may be a weird blank char or something, I'm not sure.

Cool. Thanks @jaredcwhite ---------------------------------------------------------------------------------------------------- [23:55:10] Vais Salikhov(@vais):@fkchang wow re what_methods, didn't know that even existed, cool! Re being able to lookup code/comments, at the risk of this starting to sound like the beginning of the [stone soup story](http://en.wikipedia.org/wiki/Stone_Soup), I think the next step is for you to express your vision for this capability as a set of executable failing specs :wink2: Then someone could just make those specs pass, and... the end. This would really take a lot of guesswork (and design work) out of it. I know I would never have gotten involved with Opal if not for rubyspec. It made it a no-brainer to contribute. ---------------------------------------------------------------------------------------------------- [01:37:11] Rick Carlino(@RickCarlino):@jaredcwhite Thanks for the confirmation email. Pretty sure I forgot that I sent it to you and may have inadvertently double posted. Sorry if that was the case. ---------------------------------------------------------------------------------------------------- [02:11:47] Rick Carlino(@RickCarlino):So what are the most actively maintained front end frameworks in Opal?

To some extent you can do that now w/opal-irb, but my ultimate goal is much more ambitious, ala this prototype https://www.youtube.com/watch?v=TRkhihHVLzQ -- though most people haven't worked w/lisp machines or smalltalk, so they don't really get what I'm pitching, from what I can tell ---------------------------------------------------------------------------------------------------- [21:16:51] Hampton Catlin(@hcatlin):hahahaa... that's intense. ---------------------------------------------------------------------------------------------------- [21:17:42] Hampton Catlin(@hcatlin):i'm currently trying to get something to just display on a the page with the sinatra app... ---------------------------------------------------------------------------------------------------- [21:17:54] Hampton Catlin(@hcatlin):I feel like I'm missing something obvious here. ---------------------------------------------------------------------------------------------------- [21:18:16] Hampton Catlin(@hcatlin):Like, I know this is general purpose Ruby->JS, and not a framework, but I'm trying to figure out how to work with the browser itself. ---------------------------------------------------------------------------------------------------- [21:18:49] Elia Schito(@elia):it's either opal-jquery or opal-browser ---------------------------------------------------------------------------------------------------- [21:19:02] Elia Schito(@elia):the alternative is using native.rb ---------------------------------------------------------------------------------------------------- [21:19:18] Forrest Chang(@fkchang):@hcatlin re, getting started, I feel your pain. I started (but never completed) https://github.com/fkchang/opal-starter-kit w/the intention of making getting started 2 steps --- also to officially document the correct ways to setup ---------------------------------------------------------------------------------------------------- [21:19:25] Hampton Catlin(@hcatlin):vienna doesn't cover it ---------------------------------------------------------------------------------------------------- [21:19:29] Hampton Catlin(@hcatlin):oh!... let me check that out. ---------------------------------------------------------------------------------------------------- [21:19:43] Elia Schito(@elia):vienna it's based on opal-jquery ---------------------------------------------------------------------------------------------------- [21:20:24] Forrest Chang(@fkchang):@hcatlin opal-browser covers a lot more functionality than jquery, -- canvas, websql, websockets, etc. but you might be more comfortable w/opal-jquery if your a jquery person ---------------------------------------------------------------------------------------------------- [21:21:30] Forrest Chang(@fkchang):@hcatlin re frameworks, there's vienna, lissio that are more mature, and new ones like volt, clearwater, opal-react that I know of ---------------------------------------------------------------------------------------------------- [21:21:52] Hampton Catlin(@hcatlin):I guess I'm looking for a template folder I can setup... ---------------------------------------------------------------------------------------------------- [21:22:02] Hampton Catlin(@hcatlin):And where I can just write some CSS and get to building something. ---------------------------------------------------------------------------------------------------- [21:22:20] Hampton Catlin(@hcatlin):Models are less important... ---------------------------------------------------------------------------------------------------- [21:23:29] Hampton Catlin(@hcatlin):I guess I mean server-side support, more than an intense browser framework. ---------------------------------------------------------------------------------------------------- [21:23:39] Hampton Catlin(@hcatlin):The starter-kit seems pretty close. ---------------------------------------------------------------------------------------------------- [21:26:08] Forrest Chang(@fkchang):@hcatlin yeah, so if opal-starter-kit was coded against like opal 0.5 ish, I've been meaning to revisit. I think the most bells and whistles out of the box is to setup opal-rails ---------------------------------------------------------------------------------------------------- [21:26:35] Forrest Chang(@fkchang):then you can just edit the haml and the opal code w/o having to set stuff up ---------------------------------------------------------------------------------------------------- [21:27:37] Forrest Chang(@fkchang):It's nice to just use the rails conventions, write opal in both *.js.rb files and via the :opal filter in haml ---------------------------------------------------------------------------------------------------- [21:28:33] Hampton Catlin(@hcatlin):my goal is to have this thing be fully static... so I might give opal-jquery a try. ---------------------------------------------------------------------------------------------------- [21:30:24] Forrest Chang(@fkchang):@hcatlin I think starting w/opal-rails makes it easy to get started and monkey w/stuff and then you can switch to generating a static app. When I get around to updating the starter kit, I'm going to make the static recipe, include opal server, so you can dev against it, and have a rake task to generate the static app. ---------------------------------------------------------------------------------------------------- [21:30:40] meh.(@meh):hcatlin, if you want something fully static, check out lissio ---------------------------------------------------------------------------------------------------- [21:31:01] meh.(@meh):hcatlin, I built an Overwolf app with it, just generates the index.html with everything in and it werks ---------------------------------------------------------------------------------------------------- [21:31:24] meh.(@meh):hcatlin, but it's probably going to feel weird if you're used to MVC ---------------------------------------------------------------------------------------------------- [21:36:30] Elia Schito(@elia):this might be of interest http://dev.mikamai.com/post/96967839924/dead-simple-view-layer-with-opal-and-jquery ---------------------------------------------------------------------------------------------------- [21:40:02] Hampton Catlin(@hcatlin):that sounds good! ---------------------------------------------------------------------------------------------------- [21:40:23] Hampton Catlin(@hcatlin):@meh I'm pretty used to new things. ;) ---------------------------------------------------------------------------------------------------- [21:43:15] Hampton Catlin(@hcatlin):feeling a bit overwhelmed by choice here... looking around the Todo app ---------------------------------------------------------------------------------------------------- [21:54:42] Forrest Chang(@fkchang):@hcatlin lissio's all ruby - component based approach really appealed to me ---------------------------------------------------------------------------------------------------- [21:55:55] Forrest Chang(@fkchang):Re: choice, I find w/Opal a lot of time I find I "don't need no stinking frameworks", that opal-inspect prototype is mostly just raw opal w/some opal-jquery

---------------------------------------------------------------------------------------------------- [22:00:09] Hampton Catlin(@hcatlin):any hints? ---------------------------------------------------------------------------------------------------- [22:00:27] Elia Schito(@elia):self.map comes from sprockets 3 ---------------------------------------------------------------------------------------------------- [22:00:58] Elia Schito(@elia):so it might be a good idea to downgrade to 2 until i fix it properly ---------------------------------------------------------------------------------------------------- [22:01:28] Forrest Chang(@fkchang):@hcatlin Opal-inspector prototype was surprisingly small amount of code too, I talk about how how little code it was and not the need for a framework at about 23:40 in https://www.youtube.com/watch?v=GH9FAfKG-qY -- that video is good coz it's a very broad overview of everything in Opal at that time: has a better opal inspector demo than the dedicated youtube, I show off some lissio too ---------------------------------------------------------------------------------------------------- [22:01:31] Elia Schito(@elia):sourcemaps will be a hack on top of sprockets until v4 (of sprockets) ---------------------------------------------------------------------------------------------------- [22:02:52] Hampton Catlin(@hcatlin):np ---------------------------------------------------------------------------------------------------- [22:03:40] Elia Schito(@elia):about the blank page I need to know which opal version you're using,

Thanks @elia ---------------------------------------------------------------------------------------------------- [22:04:15] Elia Schito(@elia)::+1: ---------------------------------------------------------------------------------------------------- [22:04:18] Hampton Catlin(@hcatlin):and, I got stuff displaying. had the wrong #element ---------------------------------------------------------------------------------------------------- [22:06:46] Forrest Chang(@fkchang):@elia u did the source maps support, IIRC? ---------------------------------------------------------------------------------------------------- [22:09:02] Elia Schito(@elia):@fkchang I hacked in something initially, based on comments (similarly to those you see in sass), but then @adambeynon added support at compiler level ---------------------------------------------------------------------------------------------------- [22:09:48] Forrest Chang(@fkchang):so then @adambeynon is the one to ask to see if we could reuse stuff in source maps to provide the code/comment lookup stuff I want ---------------------------------------------------------------------------------------------------- [22:11:45] Elia Schito(@elia):yes, sorry ---------------------------------------------------------------------------------------------------- [22:13:24] Forrest Chang(@fkchang):rats... ---------------------------------------------------------------------------------------------------- [22:13:37] Forrest Chang(@fkchang):expecting @vais to have a stroke of genius now ---------------------------------------------------------------------------------------------------- [22:14:40] Elia Schito(@elia):well, the compiler stuff is really readable and OO, you have to look into lib/opal/nodes ---------------------------------------------------------------------------------------------------- [22:17:33] meh.(@meh):as long as it's not parser related it's fairly simple ---------------------------------------------------------------------------------------------------- [22:51:12] Jeremy Evans(@jeremyevans):I've been playing around with the new Opal::TiltTemplate stuff, and I've found that it doesn't work well when you need to require something in the stdlib or let's says opal/jquery, or maybe I'm doing it wrong ---------------------------------------------------------------------------------------------------- [22:51:19] Jeremy Evans(@jeremyevans):I think if TiltTemplate could optionally call Opal::Builder instead of Opal::Compiler, this may fix the issue ---------------------------------------------------------------------------------------------------- [22:51:25] Jeremy Evans(@jeremyevans):e.g. if you do Tilt.new('foo.rb', :build=>true).render # use Opal::Builder, not Opal::Compiler ---------------------------------------------------------------------------------------------------- [22:51:32] Jeremy Evans(@jeremyevans):Before I head further down that path, I'd like to get a sanity check from an opal developer to make sure that makes sense ---------------------------------------------------------------------------------------------------- [22:52:11] Elia Schito(@elia):@jeremyevans just to be sure I understand your goal, you still want to avoid sprockets? ---------------------------------------------------------------------------------------------------- [22:53:12] Jeremy Evans(@jeremyevans):Yes ---------------------------------------------------------------------------------------------------- [22:53:30] Elia Schito(@elia):ok, then Opal::Builder is the way to go ---------------------------------------------------------------------------------------------------- [22:54:04] Jeremy Evans(@jeremyevans):OK. So does a :build option to Opal::TiltTemplate to support Opal::Builder make sense? ---------------------------------------------------------------------------------------------------- [22:55:15] Elia Schito(@elia):like `build: true`? to which method you want to pass the option? ---------------------------------------------------------------------------------------------------- [22:55:22] Jeremy Evans(@jeremyevans):Tilt.new ---------------------------------------------------------------------------------------------------- [22:57:48] Elia Schito(@elia):ok, so, I don't know that well Tilt, but looking at the TiltTemplate source I think it could make sense to just use the builder and let the user control the build with `require` ---------------------------------------------------------------------------------------------------- [22:58:17] Elia Schito(@elia):basically what you want is to replicate the tilt based Processor from opal 0.7 ---------------------------------------------------------------------------------------------------- [22:58:48] Elia Schito(@elia):https://github.com/opal/opal/blob/0-7-stable/lib/opal/sprockets/processor.rb#L68-L83 ---------------------------------------------------------------------------------------------------- [22:59:53] Jeremy Evans(@jeremyevans):Yes, similar, but instead of having sprockets doing things, just leave everything to Opal::Builder, since it seems like Opal::Builder can handle things without sprockets ---------------------------------------------------------------------------------------------------- [23:00:45] Jeremy Evans(@jeremyevans):I mean, if you are using sprockets directives in your code, then using sprockets makes sense, but if you aren't using sprockets directives, it seems unnecessary to try to use sprockets ---------------------------------------------------------------------------------------------------- [23:00:50] Elia Schito(@elia):yes, I struggled to make them work together but gave up :) ---------------------------------------------------------------------------------------------------- [23:01:44] Elia Schito(@elia):I still like sprockets for the compilation minification etc. ---------------------------------------------------------------------------------------------------- [23:03:01] Elia Schito(@elia):@jeremyevans to skip sprockets you just don't pass a special path_reader ---------------------------------------------------------------------------------------------------- [23:03:01] Elia Schito(@elia):https://github.com/opal/opal/blob/0-7-stable/lib/opal/sprockets/processor.rb#L111-L116 ---------------------------------------------------------------------------------------------------- [23:04:12] Elia Schito(@elia):and you can also skip passing an array of already required stuff (`prerequired`) ---------------------------------------------------------------------------------------------------- [23:04:13] Elia Schito(@elia):https://github.com/opal/opal/blob/0-7-stable/lib/opal/sprockets/processor.rb#L75 ---------------------------------------------------------------------------------------------------- [23:04:34] Jeremy Evans(@jeremyevans):I'm developing with 0.8.0 beta1, do you think I should use the sprockets-specific stuff, or is it safe to just rely on Opal::Builder? ---------------------------------------------------------------------------------------------------- [23:05:51] Elia Schito(@elia):I'm kinda evaluating if having a "sprockets-free" codepath still valuable as the more I was trying to make it work the more I found I was reimplementing sprockets ---------------------------------------------------------------------------------------------------- [23:06:10] Elia Schito(@elia):your use case makes a point I think ---------------------------------------------------------------------------------------------------- [23:08:05] Elia Schito(@elia):also I think that when I'll switch to the new style of sprockets processor api (#call based) they could share most code, just a supposition though ---------------------------------------------------------------------------------------------------- [23:09:42] Jeremy Evans(@jeremyevans):It really depends if the long term goal is to depend on sprockets or move away from sprockets. Personally, I like the fact that you can use Opal like any other template library, independent of sprockets. But I may be in the minority :) ---------------------------------------------------------------------------------------------------- [23:10:53] Elia Schito(@elia):maybe it forces it to stay a bit more general and not too tied to sprockets ---------------------------------------------------------------------------------------------------- [23:12:20] Elia Schito(@elia):anyway for now the builder won't go anywhere, it might lose some sprockets-like features in the future bu that's not a problem I guess ---------------------------------------------------------------------------------------------------- [23:13:26] Elia Schito(@elia):thinking out loud, the other thing that sprockets facilitates on the other hand is plugins and alternative processors like opal-haml or react.rb jsx support ---------------------------------------------------------------------------------------------------- [23:14:22] Jeremy Evans(@jeremyevans):Good to know. I've got to go now, I'll try to check back in tomorrow. ---------------------------------------------------------------------------------------------------- [23:14:29] Elia Schito(@elia):@jeremyevans keep me posted on your experience, real world always beats mumbling :P ---------------------------------------------------------------------------------------------------- [23:14:56] Jeremy Evans(@jeremyevans):Definitely. I'm liking things so far. ---------------------------------------------------------------------------------------------------- [23:15:38] Elia Schito(@elia):always good to hear! ---------------------------------------------------------------------------------------------------- [00:05:46] Forrest Chang(@fkchang):@vais, I could certainly write some specs, or at least some pseudo spec. If the caller is in the same place as the where Opal code is compiled, it'd be relatively easy. A potential issue is then you'd have to package the indexing of such which could be quite large. I would probably want to have it on demand the info, similar to source maps, but I guess 1 step at a time. ---------------------------------------------------------------------------------------------------- [00:09:25] Forrest Chang(@fkchang):perhaps @adambeynon has some ideas, but I'm foreseeing something like this * static app - prepackage indexing w/app via a compile option * app w/ruby based server, possible to prepack via same compile option or, with some sort of rack middle ware that servers up info on demand much like source maps, which accesses on demand some output the compiler emited when it was compiled Ultimately in something like opal-inspector, I would override the mapping w/code that is evaluated in browser, so I would also want the ability to send it back to the server, but that's out of scope for the feature I'm asking and more in the middle ware. So I guess I'd start with the compile option ---------------------------------------------------------------------------------------------------- [00:10:56] Vais Salikhov(@vais):@fkchang any idea how this is done on MRI (in pry for example)? Would that approach not work for what your are trying to accomplish? ---------------------------------------------------------------------------------------------------- [00:14:03] Forrest Chang(@fkchang):@vais I don't know how it's done in pry, but I'd guess it has some index and servers up the files off the file system, which described like that is close to what the source maps do ---------------------------------------------------------------------------------------------------- [00:15:53] Forrest Chang(@fkchang):Pry's example might provide insight, wouldn't be surprised if it dropped in to C to do it though. Maybe @elia can provide some source map insights ---------------------------------------------------------------------------------------------------- [00:17:25] Forrest Chang(@fkchang):You ultimate need to index a method entity with code that was compiled, @adambeynon suggested some AST traversing for part of that. Then you'd store it somewhere. Packaging could be as easy as global hash or similar. ---------------------------------------------------------------------------------------------------- [00:19:50] Vais Salikhov(@vais):@fkchang this does sound very close to what sourcemaps do. I have no idea how sourcemaps work, so that would be the place I'd start to figure this out. And yes, the difference with MRI is that it has direct access to the source files on disk. So, it looks like sourcemaps would play into this one way or another. ---------------------------------------------------------------------------------------------------- [00:21:12] Forrest Chang(@fkchang):Step one I'd go with fully qualified method names ```ruby $method_lookup = { 'Mod::Class1#foo' => "def foo (param)\n blah(param)\nend" } ``` ---------------------------------------------------------------------------------------------------- [00:32:32] Forrest Chang(@fkchang):@vais I added a pseudo spec to https://github.com/opal/opal/issues/840 -- tell me if it makes sense ---------------------------------------------------------------------------------------------------- [10:26:01] Vais Salikhov(@vais):@fkchang makes sense ;) ---------------------------------------------------------------------------------------------------- [11:08:19] Vais Salikhov(@vais):@elia, you there? ---------------------------------------------------------------------------------------------------- [11:09:33] Vais Salikhov(@vais):I'm trying to run `bundle exec rake dist` on the latest master, and it chokes: ``` * building math... done. (development: 10.93KB, minified: 7.63KB, gzipped: 1.26KB). * building minitest... rake aborted! Sprockets::FileNotFound: couldn't find file 'optparse' (in /Users/vais/GitHub/opal/stdlib/minitest.rb) ``` ---------------------------------------------------------------------------------------------------- [11:10:38] Vais Salikhov(@vais):This is in regards to jshint, I want to run it locally, so I need `rake dist` which I've never used before. ---------------------------------------------------------------------------------------------------- [11:10:53] Vais Salikhov(@vais):Any ideas? ---------------------------------------------------------------------------------------------------- [12:04:00] Vais Salikhov(@vais):@elia weird, I checked out your upstream/jshint branch, and I'm still getting an error, but it's a different one: ``` * building math... done. (development: 10.93KB, minified: 7.63KB, gzipped: 1.26KB). * building minitest... rake aborted! Sprockets::CircularDependencyError: /Users/vais/GitHub/opal/stdlib/minitest.rb has already been required ``` ---------------------------------------------------------------------------------------------------- [14:38:50] Forrest Chang(@fkchang):@vais @elia when I was describing the process outload, maybe we could just slightly piggy back on the source maps mechanism. We already map lines of code to source maps, maybe the indexing by method comment simply generates the same sort of mapping of method/comment to source code? ---------------------------------------------------------------------------------------------------- [14:39:01] Forrest Chang(@fkchang):this w/o knowing how the source maps are implemented at all ---------------------------------------------------------------------------------------------------- [14:39:34] Forrest Chang(@fkchang):@jaredcwhite good editorial summary/copy on the opalist! kudos ---------------------------------------------------------------------------------------------------- [15:57:52] Jared White(@jaredcwhite):@fkchang Thanks man. Yeah, I enjoyed reading about your dev experience on the project. ---------------------------------------------------------------------------------------------------- [18:47:25] Jose Bencosme(@jlbenc):Hello, all. Avdi mentioned Volt on the Ruby Rogues latest episode (#207, around ~40:00). Go Opal! :) ---------------------------------------------------------------------------------------------------- [18:47:41] Rick Carlino(@RickCarlino):Awesome! ---------------------------------------------------------------------------------------------------- [18:48:30] Jose Bencosme(@jlbenc):Simple mention, but nice anyway! ---------------------------------------------------------------------------------------------------- [19:54:59] Elia Schito(@elia):https://twitter.com/hcatlin/status/598575698148622336 ---------------------------------------------------------------------------------------------------- [20:12:02] Hampton Catlin(@hcatlin):hahahaha ---------------------------------------------------------------------------------------------------- [20:12:06] Hampton Catlin(@hcatlin):YOU ARE TALKING ABOUT ME ---------------------------------------------------------------------------------------------------- [20:12:22] Forrest Chang(@fkchang):@hcatlin just about to respond to that tweet ---------------------------------------------------------------------------------------------------- [20:13:48] Hampton Catlin(@hcatlin):My current startup is an open sourced Ember app with a Rails API backend. I'm not disappointed with Ember, but I'm also not 100% happy with it. ---------------------------------------------------------------------------------------------------- [20:14:27] Hampton Catlin(@hcatlin):I'm needing to build a simple side-site, that's pretty interaction heavy... and so I've been evaluating different options. ---------------------------------------------------------------------------------------------------- [20:14:49] Forrest Chang(@fkchang):@hcatlin what are you not happy about wrt to ember? There are certain perks that I think opal brings out of the box, they may or may not address your grievances w/ember ---------------------------------------------------------------------------------------------------- [20:15:48] Hampton Catlin(@hcatlin):There are a lot of best-practices that aren't written down, and vague references to how you are doing it wrong (by following the public guides)... which is kind of an odd feeling. ---------------------------------------------------------------------------------------------------- [20:16:02] Hampton Catlin(@hcatlin):And, there are definitely funny edge cases all over the place that aren't covered at all. ---------------------------------------------------------------------------------------------------- [20:16:43] Hampton Catlin(@hcatlin):Odd behaviours that are hard to tell if it's a bug or something I did or a best practice I never read or, more typically, just an "edge case" that they haven't gotten to yet. ---------------------------------------------------------------------------------------------------- [20:17:14] Hampton Catlin(@hcatlin):The thing I *love* is the fast auto-reloader of Ember-CLI. ---------------------------------------------------------------------------------------------------- [20:17:32] Hampton Catlin(@hcatlin):But, I freaking hate that to upgrade, I have to *delete the node_modules and bower_components* folder to get it tow rok. ---------------------------------------------------------------------------------------------------- [20:17:34] Hampton Catlin(@hcatlin):work* ---------------------------------------------------------------------------------------------------- [20:20:54] Hampton Catlin(@hcatlin):I don't think Opal directly solves any of those, tbh, but I'd rather deal with trying to translate Ruby concepts into interactive apps, then wrangling with weird prototype-object behaviours and weird NPM side-effects. ---------------------------------------------------------------------------------------------------- [20:22:32] Hampton Catlin(@hcatlin):I kind of think Opal + React could be interesting. ---------------------------------------------------------------------------------------------------- [20:23:51] Hampton Catlin(@hcatlin):Writing pure Javascript makes me use patterns again, just like when I used to write Java.

Rails hasn't the shiny new thing for a while. I would think Opal would help a lot to match the "js on the backend allows the js people to leverage their skills there" argument for Rubyists the other way, but again we have the whole adoption issues I quoted from the Rust critique to address. Ultimately, my opinion, is "if they want Javascript, they can have it." I'm about spreading the joy of Ruby, extended outside of it's traditional place in to the web front end w/Opal, scaling the backend w/Jubliee/vert.x, etc... ---------------------------------------------------------------------------------------------------- [17:02:46] Forrest Chang(@fkchang):Ruby everywhere is an advantage, IMO, so we don't need to conquer the world, just thrive. ---------------------------------------------------------------------------------------------------- [19:30:13] Jeremy Evans(@jeremyevans):I've just added pull request #864 which makes tilt/opal able to build opal projects that use require (and probably require_tree) without using sprockets.

I need to clean up its Opal bindings, though. ---------------------------------------------------------------------------------------------------- [18:43:18] Jamie Gaskins(@jgaskins):@fkchang I'm not actually reimplementing Paggio, though. Just added some convenience methods to a mixin to sanitize and generate nodes for that virtual DOM implementation. ---------------------------------------------------------------------------------------------------- [18:44:41] Jamie Gaskins(@jgaskins):The idea is that, as long as an object's `render` method returns a scalar, a virtual DOM node, or an array of any combination of those, that's all that's needed. ---------------------------------------------------------------------------------------------------- [18:56:19] Forrest Chang(@fkchang):@jgaskins yours doesn't look as close to paggio as some others I've seen ---------------------------------------------------------------------------------------------------- [20:27:24] Elia Schito(@elia):@fkchang dang it! you exposed my little scheme! ---------------------------------------------------------------------------------------------------- [21:02:12] Forrest Chang(@fkchang):@elia if it makes @adambeynon blog, it'll be worth it ---------------------------------------------------------------------------------------------------- [21:02:35] Forrest Chang(@fkchang):BTW, I added the global and class dot completion to opal-irb ---------------------------------------------------------------------------------------------------- [21:19:38] Elia Schito(@elia):@fkchang great stuff! can't wait to try it ---------------------------------------------------------------------------------------------------- [21:24:48] Forrest Chang(@fkchang):@adambeynon I'm using regexps for the tab completion, I suppose I should probably use some kind of AST assist instead, as I want to support fully qualified classnames which means changing the regexps ---------------------------------------------------------------------------------------------------- [00:02:12] Jeremy Evans(@jeremyevans):@elia A couple other questions. 1) How would you feel about moving sprockets from a runtime dependency to a development dependency, and having the tilt runtime dependency support >=1.4? 2) Would you consider supporting syntax allowing you to call javascript methods (e.g. obj.$method() in ruby calls obj.method() in javascript)? ---------------------------------------------------------------------------------------------------- [09:03:45] Adam Beynon(@adambeynon):@jeremyevans I have looked at a syntax based way to call into javascript land, and in honesty it is something I would love to add. It’s just a matter of deciding on something that won’t break anything on the ruby side ---------------------------------------------------------------------------------------------------- [09:04:30] Adam Beynon(@adambeynon):Originally Opal did use obj::foo() style calls to compile down into regular javascript calls, but as we started using ruby libraries, such as rspec, mspec etc it was no longer viable ---------------------------------------------------------------------------------------------------- [09:05:09] Adam Beynon(@adambeynon):I also wondered about something like a compiler trigger ---------------------------------------------------------------------------------------------------- [09:05:38] Adam Beynon(@adambeynon):object.js.foo() would compile to `object.foo()`, or someything like that (and perhaps something better than `.js`) ---------------------------------------------------------------------------------------------------- [09:05:53] Adam Beynon(@adambeynon):but, any suggestions would be great :+1: ---------------------------------------------------------------------------------------------------- [09:08:25] Adam Beynon(@adambeynon):@fkchang autocomplete stuff is looking great! :smile: ---------------------------------------------------------------------------------------------------- [11:52:37] Elia Schito(@elia):@adambeynon ping, you have a minute? ---------------------------------------------------------------------------------------------------- [11:53:49] Elia Schito(@elia):``` def has_attribute?(name) `!!self.attr(name)` end ``` ---------------------------------------------------------------------------------------------------- [11:53:57] Elia Schito(@elia):I think should be: ---------------------------------------------------------------------------------------------------- [11:54:25] Elia Schito(@elia):``` def has_attribute?(name) `self.attr(name) !== undefined` end ``` but it can potentially break apps ---------------------------------------------------------------------------------------------------- [11:55:17] Elia Schito(@elia):(backstory is that jquery returns an empty string if the attribute is there but has no value set) ---------------------------------------------------------------------------------------------------- [11:56:15] Adam Beynon(@adambeynon):@elia yes, agree with that.

I have 2 examples of things that can really throw you off * if a spec file doesn't compile, the spec runner just ignores it, so you can get green, so if u don't pay attention to the spec count, you think the build is passing. * no stack trace when there is an error. I'm having this issue right now where specs that should pass cause a bunch of stuff totally unrelated to break, comment them out, and everything is normal. The only info is this ``` TypeError: wrong argument type Method (expected Proc/Method) ``` ---------------------------------------------------------------------------------------------------- [17:46:00] Mitch VanDuyn(@catmando):Is there any hacky way to get the callers binding ---------------------------------------------------------------------------------------------------- [17:46:10] Mitch VanDuyn(@catmando):In opal? ---------------------------------------------------------------------------------------------------- [17:48:30] Mitch VanDuyn(@catmando):In other words how to implement binding soft caller gem in opal.

A blog post or 3 would make good material for the opalist (hope @jaredcwhite doesn't mind me pimping that) for the greater opal publicity ---------------------------------------------------------------------------------------------------- [18:03:12] Forrest Chang(@fkchang):related @AstonJ suggested something about a publicity committee or similar? We should definitely do that since I think we have enough "highly enthused" ppl here. Maybe merging w/volt's committee is the thing to do? ---------------------------------------------------------------------------------------------------- [18:04:17] Elia Schito(@elia):@ylluminate any way to see it without logging into fb? ---------------------------------------------------------------------------------------------------- [18:28:39] Jared White(@jaredcwhite):@jeremyevans What about hash syntax with the proposed .JS syntax? Aka `some object.JS.somemethod({foo: "bar"})` -- I'm wondering if that passes on a regular JS hash-style object to the method or an Opal hash which wouldn't be compatible. ---------------------------------------------------------------------------------------------------- [18:32:29] Jeremy Evans(@jeremyevans):@jaredcwhite I assume that would pass the ruby/opal hash, you'd have to use `some object.JS.somemethod({foo: "bar"}.to_n)` to pass the javascript object ---------------------------------------------------------------------------------------------------- [18:32:57] meh.(@meh):jeremyevans, you should probably insert a Native.try_convert ---------------------------------------------------------------------------------------------------- [18:33:02] meh.(@meh):implicitly ---------------------------------------------------------------------------------------------------- [18:33:06] meh.(@meh):when calling a method with JS ---------------------------------------------------------------------------------------------------- [18:33:44] Jeremy Evans(@jeremyevans):@meh doesn't that require loading native from the stdlib, which the runtime can't depend on? ---------------------------------------------------------------------------------------------------- [18:34:13] meh.(@meh):jeremyevans, becomes simple when it's an option ---------------------------------------------------------------------------------------------------- [18:35:27] meh.(@meh):jeremyevans, that's also why I'd go with the disable by default ---------------------------------------------------------------------------------------------------- [18:35:47] meh.(@meh):I'd rather keep the standard semantics with the default options, and not everyone needs that kind of stuff in their code ---------------------------------------------------------------------------------------------------- [18:35:57] meh.(@meh):but we do need at least per-gem options ---------------------------------------------------------------------------------------------------- [18:36:03] meh.(@meh):per-file would be good too ---------------------------------------------------------------------------------------------------- [18:36:44] meh.(@meh):basically I'm all for this thing if it seamlessly uses Native as well, and it's disabled by default ---------------------------------------------------------------------------------------------------- [18:37:10] meh.(@meh):it's a nice ergonomic thing when you're dealing with native stuff, i.e. porting something or writing a wrapper ---------------------------------------------------------------------------------------------------- [18:37:18] meh.(@meh):but when writing Opal code you should never, ever, access JS ---------------------------------------------------------------------------------------------------- [18:37:37] meh.(@meh):it should all be hidden behind wrappers ---------------------------------------------------------------------------------------------------- [18:38:02] meh.(@meh):if you're writing js in your application you're doing something wrong unless it's for optimization ---------------------------------------------------------------------------------------------------- [18:40:21] Jeremy Evans(@jeremyevans):The main reason for adding this is so I can easily write ruby instead of javascript, with minimal invasion. I would like to be able to incrementally replace javascript with ruby, which is really ugly if you have to manually wrap and unwrap javascript objects everywhere. ---------------------------------------------------------------------------------------------------- [18:41:20] Jeremy Evans(@jeremyevans):I think per-file options would be possible using magic comments, but I can't think of another good way to do so ---------------------------------------------------------------------------------------------------- [18:42:46] Jeremy Evans(@jeremyevans):Really, if you should never, ever, access JS, opal should be implicitly converting all function arguments to ruby objects, and converting all function return values to javascript objects if they weren't called by ruby code. That would probably slow things down quite a bit, though. ---------------------------------------------------------------------------------------------------- [18:46:36] Jeremy Evans(@jeremyevans):I have a more pragmatic viewpoint. If you are running on a javascript runtime, you'll eventually need to deal with javascript objects, so you might as well make that as easy as possible. ---------------------------------------------------------------------------------------------------- [18:53:20] Elia Schito(@elia):I had a hard time too trying to deal with native libs http://dev.mikamai.com/post/87806500959/learning-d3-js-basics-with-ruby-and-opal ---------------------------------------------------------------------------------------------------- [19:02:38] meh.(@meh):jeremyevans, the point is JS is treated like FFI ---------------------------------------------------------------------------------------------------- [19:02:56] meh.(@meh):we're running on it, but that doesn't mean it should be seamless, and it doesn't work ---------------------------------------------------------------------------------------------------- [19:03:08] meh.(@meh):when you need to go down to raw JS is to use APIs written in it ---------------------------------------------------------------------------------------------------- [19:03:16] meh.(@meh):and that's where writing a Ruby-esque wrapper comes in ---------------------------------------------------------------------------------------------------- [19:03:27] meh.(@meh):you do it, release it, and everyone's happier ---------------------------------------------------------------------------------------------------- [20:11:39] Christian Käser(@dfyx):Just some experiment to get opal running with electron: ---------------------------------------------------------------------------------------------------- [20:11:41] Christian Käser(@dfyx): require 'opal' require 'opal-electron/app' require 'opal-electron/browser_window' require 'opal-electron/crash_reporter' require 'opal-electron/process' CrashReporter::start App::on 'window-all-closed' do App::quit if Process::platform != 'darwin' end App::on 'ready' do main_window = BrowserWindow.new(width: 800, height: 600) main_window.load_url_relative 'index.html' end ---------------------------------------------------------------------------------------------------- [20:11:44] Christian Käser(@dfyx):Works ---------------------------------------------------------------------------------------------------- [20:11:53] Christian Käser(@dfyx):All those requires are pretty simple ---------------------------------------------------------------------------------------------------- [20:12:50] Christian Käser(@dfyx):(I just wrapped everything I needed in ruby classes) ---------------------------------------------------------------------------------------------------- [23:06:52] AstonJ(@AstonJ):@AstonJ Want to join the strategies team? ---------------------------------------------------------------------------------------------------- [23:07:45] AstonJ(@AstonJ): Hey @/all We have just started a new team for anyone interested in helping out with the some of the behind-the-scenes stuff, marketing and promotion of the Opal and Volt projects (in fact any Opal related project).

I am working with the react.rb gem. Currently when you do a require, you say: `require 'react'` but this keeps causing all sorts of problems because of the name space collision with the react.js library. I want to change things so that you say `require 'opal-react'` (like `opal-jquery`) but still use the `React` name space within opal to refer to the opal wrapper. (I assume this is okay with the opal team, if not then something like ruby-react would be fine) This is a dumb question I think, but I am not seeing how this is done with opal-jquery. THANKS IN ADVANCE! ---------------------------------------------------------------------------------------------------- [14:05:55] Elia Schito(@elia):@catmando you should consider them as normal ruby requires and actively forgot the special bound between module/class naming and file names that rails adds ---------------------------------------------------------------------------------------------------- [14:07:00] Elia Schito(@elia):also think of js files as native libs, the same way as you require a `.so` file in MRI ---------------------------------------------------------------------------------------------------- [14:07:19] Elia Schito(@elia):(not that that happens often, but the idea it's the same) ---------------------------------------------------------------------------------------------------- [14:09:16] Mitch VanDuyn(@catmando):@elia well, the problems I keep having is with using react.rb in rails... I am pretty sure its because of the specific name "react.rb". I worked around the first set of problems, but now am getting things working with rails-react, and I am back into the middle of these issues. I have no problems using other opal gems, so I am assuming I just need to change the name of react.rb to something else. ---------------------------------------------------------------------------------------------------- [14:09:38] Mitch VanDuyn(@catmando):But I would like to keep it so that within the opal code you can still just use the Module "React". ---------------------------------------------------------------------------------------------------- [14:10:18] Elia Schito(@elia):@catmando just renaming the files and updating the requires should do the job ---------------------------------------------------------------------------------------------------- [14:10:34] Mitch VanDuyn(@catmando):I am pretty if I just change the whole gem to say "reactrb" and call the outer scope ReactRB things will work fine ---------------------------------------------------------------------------------------------------- [14:11:17] Mitch VanDuyn(@catmando):But I would prefer if possible to be able to use React inside Opal while requiring 'opal-react'. ---------------------------------------------------------------------------------------------------- [14:11:33] Mitch VanDuyn(@catmando):I think this is essentially what was done with opal-jquery as well. ---------------------------------------------------------------------------------------------------- [14:12:10] Elia Schito(@elia):@catmando have you tried it? it should work fine… ---------------------------------------------------------------------------------------------------- [14:12:25] Elia Schito(@elia):let me know if you get any specific error ---------------------------------------------------------------------------------------------------- [14:12:52] Elia Schito(@elia):and remember that module namespace doesn't need to match filenames ---------------------------------------------------------------------------------------------------- [14:12:57] Mitch VanDuyn(@catmando):So you think if I just change the gem name to "opal-react" from "react.rb" things should work? ---------------------------------------------------------------------------------------------------- [14:13:54] Elia Schito(@elia):I don't think the problem is with the gem name at all ---------------------------------------------------------------------------------------------------- [14:13:55] Mitch VanDuyn(@catmando):OHHH I see...

Instant isomorphic rendering in ruby. I am proposing to react.rb's developer that we rename to opal-react. Is that okay? ---------------------------------------------------------------------------------------------------- [20:28:31] Elia Schito(@elia):@catmando sure it is ---------------------------------------------------------------------------------------------------- [20:31:54] Elia Schito(@elia):no need to ask anyway ;) ---------------------------------------------------------------------------------------------------- [20:41:01] Elia Schito(@elia):@catmando btw an example app with opal-react+react-rails+clearwater would be really cool ---------------------------------------------------------------------------------------------------- [20:41:20] Elia Schito(@elia):blog post/tut would be super :sparkles: ---------------------------------------------------------------------------------------------------- [20:41:40] Elia Schito(@elia):@catmando does this setup do server side rendering too? ---------------------------------------------------------------------------------------------------- [20:44:38] Mitch VanDuyn(@catmando):Ye'* ---------------------------------------------------------------------------------------------------- [20:48:55] Mitch VanDuyn(@catmando):@elia yep just tried a small test, but seems to work fine, server and client. The react API in ruby reads beautifully, and react integrates so easily ---------------------------------------------------------------------------------------------------- [20:49:39] Mitch VanDuyn(@catmando):I expect to have some pages on our website converted by end of week. ---------------------------------------------------------------------------------------------------- [20:50:01] Mitch VanDuyn(@catmando):Will also work on a to do demo ---------------------------------------------------------------------------------------------------- ############################## [2015-05-26] ############################## [00:31:57] Jamie Gaskins(@jgaskins):@catmando FWIW, when I was playing around with react.rb, I was able to do this, which I found to be intention-revealing: ```ruby require 'react.js' require 'react.rb' ``` ---------------------------------------------------------------------------------------------------- [00:36:23] Jamie Gaskins(@jgaskins):@elia I'm not sure how well Clearwater would work with React, at least not in the same parts of the DOM. The idea behind both virtual DOMs is that they're the only things modifying their part of the DOM tree. Once they start colliding, results are likely unpredictable. ---------------------------------------------------------------------------------------------------- [00:42:49] Jamie Gaskins(@jgaskins):@elia With that said, I think it would be a lot of fun to see if we could make react.rb components work with Clearwater. I'm not sure what that entails yet, though, because React's components are presented with just the class name. ---------------------------------------------------------------------------------------------------- [15:57:20] David Chang(@zetachang):Hey, guys. Just setup a gitter room for react.rb https://gitter.im/zetachang/react.rb ---------------------------------------------------------------------------------------------------- [15:59:35] David Chang(@zetachang):Feel free to drop a line if you got something to be discussed or stuff to share :smile: ---------------------------------------------------------------------------------------------------- [19:44:32] Rick Carlino(@RickCarlino):. #shamelessPromotion f you live in Chicago (or have dev friends in Chicago) I will be giving a talk on Volt / Opal next month.

I can make that happen. ---------------------------------------------------------------------------------------------------- [13:39:31] Francesco 'makevoid' Canessa(@makevoid):I think it will be useful for rubysts that want to start playing with opal, there are not many videos out there ---------------------------------------------------------------------------------------------------- [17:37:27] CJ Lazell(@cj):so I'm trying to find out where it appends the required js to the compiled result as I need to append code https://github.com/opal/opal/blob/master/lib/opal/sprockets/processor.rb#L43-L46 ---------------------------------------------------------------------------------------------------- [17:39:52] CJ Lazell(@cj):the result.to_s is still just the single file and doesn't include all the files js it requires ---------------------------------------------------------------------------------------------------- [17:51:47] Mitch VanDuyn(@catmando):arghh! I need to define a javascript var at the global level from within opal. I want to do something like this: ---------------------------------------------------------------------------------------------------- [17:52:08] Mitch VanDuyn(@catmando):var Foo = some_func_call() ---------------------------------------------------------------------------------------------------- [17:52:40] Mitch VanDuyn(@catmando):where Foo is the result of a function call. ---------------------------------------------------------------------------------------------------- [17:52:42] Mitch VanDuyn(@catmando):i.e. ---------------------------------------------------------------------------------------------------- [17:53:38] Jared White(@jaredcwhite):@catmando All global JS vars are essentially properties on `window`. So you can simply do `window.Foo = some_func_call()` ---------------------------------------------------------------------------------------------------- [17:53:48] Mitch VanDuyn(@catmando):yeah ---------------------------------------------------------------------------------------------------- [17:53:58] Mitch VanDuyn(@catmando):but I Foo itself is a variable ---------------------------------------------------------------------------------------------------- [17:54:11] Mitch VanDuyn(@catmando):i.e. "Foo" is the result of a function call ---------------------------------------------------------------------------------------------------- [17:54:21] Mitch VanDuyn(@catmando):do I have to use javascript eval? ---------------------------------------------------------------------------------------------------- [17:55:02] Jared White(@jaredcwhite):Not following ---------------------------------------------------------------------------------------------------- [17:57:06] Jared White(@jaredcwhite):at which ever point you have a variable that you want to assign to the global level (lets' call it local_var, in backticks you would write JS code: ---------------------------------------------------------------------------------------------------- [17:57:21] Jared White(@jaredcwhite):`window.globalVar = local_var` ---------------------------------------------------------------------------------------------------- [17:57:36] Mitch VanDuyn(@catmando):no like this ---------------------------------------------------------------------------------------------------- [17:58:08] Mitch VanDuyn(@catmando):window[name_to_be_defined] = something_else ---------------------------------------------------------------------------------------------------- [17:58:53] Jared White(@jaredcwhite):what you just wrote will work actually ---------------------------------------------------------------------------------------------------- [17:59:02] Mitch VanDuyn(@catmando):nope tried that ---------------------------------------------------------------------------------------------------- [17:59:20] Jared White(@jaredcwhite):I just tried it in my JS console: ---------------------------------------------------------------------------------------------------- [17:59:22] Jared White(@jaredcwhite):> foo = "myVar" < "myVar" > window[foo] = "something" < "something" > window.myVar < "something" ---------------------------------------------------------------------------------------------------- [18:01:39] Mitch VanDuyn(@catmando):yes lovely... I know how to do it JS ---------------------------------------------------------------------------------------------------- [18:01:43] Mitch VanDuyn(@catmando):I am trying to do it ruby ---------------------------------------------------------------------------------------------------- [18:03:03] Jared White(@jaredcwhite):You mean an Opal-context global var? Hmm, not sure about that. I always encapsulate "global" variables instead of a Ruby class or a module. ---------------------------------------------------------------------------------------------------- [18:05:13] CJ Lazell(@cj):hopefully this might help understand what I'm trying to do (sorry about the non dry code, just trying to get it working) https://gist.github.com/cj/11a226a6df25c3a49e41#file-opal-rb-L22 I'm trying to override the compile method to append some javascript. The issue is it needs all the required files included with the compiled js, but when it hits compile it's just the single file.... this hack works but there must be a better way to tell/trigger once all files are joined ---------------------------------------------------------------------------------------------------- [18:05:29] Mitch VanDuyn(@catmando):@jaredcwhite Yes, but this is for a special case (communicating to React JS via Rails-React) ---------------------------------------------------------------------------------------------------- [18:07:47] CJ Lazell(@cj):I tried wrapping it in a simple typeof check but then the code block never gets executed ---------------------------------------------------------------------------------------------------- [18:08:04] Elia Schito(@elia):@catmando with native loaded this should work ``` Native(`window`)[some_key] = whatever ``` ---------------------------------------------------------------------------------------------------- [18:09:00] CJ Lazell(@cj):I can't seem to find which opal is adding the compiled js for all the require 'foo' in a certain file ---------------------------------------------------------------------------------------------------- [18:09:04] CJ Lazell(@cj):where* ---------------------------------------------------------------------------------------------------- [18:13:47] Mitch VanDuyn(@catmando):@elia - thank you kind sir. Almost there with a very nice opal-react-rails demo! ---------------------------------------------------------------------------------------------------- [18:29:55] Mitch VanDuyn(@catmando):@elia - we are just looking at this... (works) but can you explain exactly what Native() does? ---------------------------------------------------------------------------------------------------- [19:03:46] Elia Schito(@elia):@catmando really briefly native creates a ruby object with a @native ivar that contains the native object, then uses method missing to call native methods + #[] and #[]= for properties reading/setting ---------------------------------------------------------------------------------------------------- [19:08:59] CJ Lazell(@cj):is there anyway to execute code after Opal.modules["wedge"] has been triggered ? ---------------------------------------------------------------------------------------------------- [19:09:37] CJ Lazell(@cj):I'm trying add code on compile that only gets executed once the file has been loaded including all it's requires ---------------------------------------------------------------------------------------------------- ############################## [2015-05-28] ############################## [16:14:41] Forrest Chang(@fkchang):@jaredcwhite So I dunno about others, but I'd be interested in a reminder to submit stuff for the opalist. The 2 weeks went by too fast. Thanks for including opal-irb in the issue. Though even with a warning, this was pretty swamped, Amazon told us Monday that they were going to retire our main server due to h/w degradation, so I spent the last 2 days rebuilding, testing and then deploying the replacement ---------------------------------------------------------------------------------------------------- [16:15:45] Forrest Chang(@fkchang):So I wouldn't have been able to write something up. That being said, I'll target next issue ---------------------------------------------------------------------------------------------------- [16:34:15] CJ Lazell(@cj):morning. ran into a strange issue passing blocks https://github.com/opal/opal/issues/895 ---------------------------------------------------------------------------------------------------- [19:10:10] ylluminate(@ylluminate):@all just a reminder that we're looking to get more community involvement, input and demos going for opal-phaser (https://gitter.im/orbitalimpact/opal-phaser). our goal with opal-phaser is to take advantage of this very robust and well accepted framework and make it absolutely as ruby-like as possible. we're using it for a private, rather large, application development project at the moment that we can't share, but we are more than open to getting some suggestions for demo games and such as well as input to make the api more ruby friendly. ---------------------------------------------------------------------------------------------------- [20:15:49] Forrest Chang(@fkchang):@ylluminate I'd love to read more about what you guys are doing w/opal. Surely there are some aspects you can write about even if you can't share about the large project? ---------------------------------------------------------------------------------------------------- [20:33:26] Mitch VanDuyn(@catmando):@adambeyon - we were curious over on the react.rb (opal-react) gitter about where the name opal came from... ---------------------------------------------------------------------------------------------------- [21:27:46] Jared White(@jaredcwhite):@fkchang Yikes, sorry to hear about that hassle! Yes I will try to send a reminder out the week before so people have time to get content ready. ---------------------------------------------------------------------------------------------------- ############################## [2015-05-29] ############################## [18:05:50] Mitch VanDuyn(@catmando):```ruby before(:all) do @test_chains = Hash.new(Promise.new.tap { |p| p.resolve}) end async "test 1" do @test_chains[:default].then do @test_chains[:default] = Promise.new # I will start right away async {@test_chains[:default].resolve; expect ... } end end async "test 2", test_chain: :chain_2 do etc # I will also start right away end async "test 3" do # and I will also start right away end async "test 4" do # but I wont' start until test3 finishes end async "test 5", test_chain: :chain_1 do # and I won't start until test 1 finishes end ``` ---------------------------------------------------------------------------------------------------- [18:25:35] Adam Beynon(@adambeynon):@ryanstout no, havne’t had a chance Im sorry. In honesty, im not sure if its something Im going to look to fix anytime soon. not really having time to work on web/opal stuff atm ---------------------------------------------------------------------------------------------------- [19:31:26] Ryan Stout(@ryanstout):@adambeynon no worries. I know how that goes. Would you take a PR for it? ---------------------------------------------------------------------------------------------------- [19:40:33] Mitch VanDuyn(@catmando):@ryanstout - fyi I also started on a change for this... let me know if you want to wait for me to finish it up, else I can use what you have in mind....I too want to get this fixed :-) ---------------------------------------------------------------------------------------------------- [19:42:03] Ryan Stout(@ryanstout):@catmando so the thing I'm trying to get working is making it so specs run the same in MRI and opal, so we may not have the same use cases. On the server, I can have the promises block when created. ---------------------------------------------------------------------------------------------------- [19:43:09] Mitch VanDuyn(@catmando):@ryanstout but you use async? ---------------------------------------------------------------------------------------------------- [19:45:08] Ryan Stout(@ryanstout):yea, but they are still in promises. ---------------------------------------------------------------------------------------------------- [19:45:10] Ryan Stout(@ryanstout):long story ---------------------------------------------------------------------------------------------------- [19:45:17] Ryan Stout(@ryanstout):anyway, let me know if you start on it, maybe I can help ---------------------------------------------------------------------------------------------------- [19:54:08] Mitch VanDuyn(@catmando):@catmando so roughly right should the outline I gave above work for you? I.e. async case is blocked by a promise until the previous case finishes? ---------------------------------------------------------------------------------------------------- [07:13:32] ylluminate(@ylluminate):@elia @catmando @fkchang i was thinking of something along these lines: http://f.cl.ly/items/0n1p3c1k0a1S2G322s3i/Opal%20Logo%20-%20R3.1.png ---------------------------------------------------------------------------------------------------- [07:15:12] ylluminate(@ylluminate):obviously not the 3d rendered version i'd mentioned, but this gives an idea of what i was talking about. ---------------------------------------------------------------------------------------------------- [07:28:46] Elia Schito(@elia):I like the fill color, yet I prefer a more unique shape ---------------------------------------------------------------------------------------------------- [10:14:17] Mitch VanDuyn(@catmando):I like it ---------------------------------------------------------------------------------------------------- [10:14:53] Mitch VanDuyn(@catmando):Clear message ---------------------------------------------------------------------------------------------------- [14:10:45] ylluminate(@ylluminate):I was going to change shape too @elia, but then I kept getting stuck on the importance about how we want folks to recognize that this IS "ruby" (I think a la @catmando's "clear message" conclusion). So that's why I thought I'd send this for some chatter before going any further. I do perhaps think, at the very least, I need to somehow raise the contrast of this or perhaps "opalize" the facets separately. Hmmm. ---------------------------------------------------------------------------------------------------- [14:18:16] Elia Schito(@elia):gradients and textures are not very scalable (svg-wise) ---------------------------------------------------------------------------------------------------- [14:38:18] Vais Salikhov(@vais):@ylluminate in my past life I did a short stint as a web dev at a jewelry business. Opal's never cut to have facets, it's normally more of a smooth, oblong affair. So, yes, making it look like ruby is problematic :smile: ---------------------------------------------------------------------------------------------------- [14:42:54] ylluminate(@ylluminate):LOL, that crossed my mind @vais, but that was thrown into the wind when the name "opal" was chosen for a ruby implementation. ;) ---------------------------------------------------------------------------------------------------- [14:44:54] ylluminate(@ylluminate):of course these shapes did cross my mind: http://cl.ly/image/2S1r0q1u2l44 ---------------------------------------------------------------------------------------------------- [14:45:38] Vais Salikhov(@vais):Here's a stream of consciousness.... From wikipedia "The internal structure of precious opal makes it diffract light; depending on the conditions in which it formed, it can take on many colors. " ---------------------------------------------------------------------------------------------------- [14:45:55] ylluminate(@ylluminate):http://cl.ly/image/1Q1z3T3K253A ---------------------------------------------------------------------------------------------------- [14:46:59] Vais Salikhov(@vais):http://www.puresoliloquy.com/wp-content/uploads/2013/10/pink-floyd-dark-side-of-the-moon-wallpaper-2.png ---------------------------------------------------------------------------------------------------- [14:47:25] Vais Salikhov(@vais)::wink2: ---------------------------------------------------------------------------------------------------- [14:47:41] ylluminate(@ylluminate):lol, cute ---------------------------------------------------------------------------------------------------- [14:47:49] Vais Salikhov(@vais):(with a ruby shape instead of a triangle of course) ---------------------------------------------------------------------------------------------------- [14:49:25] Vais Salikhov(@vais):Oops, that's actually not an example of diffraction :sweat_smile: ---------------------------------------------------------------------------------------------------- [14:50:23] ylluminate(@ylluminate):one problem with logos is that when we get too many mental concepts going on it wrecks havoc on the user's ability to obtain meaning. i once did a logo design for an organization about 8 years ago that caused me to not do any designs since for anyone buy my own projects because a committee had to decide on it. i went through about 200 iterations until i finally gave up, used a logo design app and used a nike-like swoosh default and they freaking loved it. -.- i was not a happy camper, but c'est la vie ---------------------------------------------------------------------------------------------------- [14:51:56] Vais Salikhov(@vais):Hehe... ---------------------------------------------------------------------------------------------------- [14:52:53] Vais Salikhov(@vais):Nike-like swoosh... that's not a bad idea! ---------------------------------------------------------------------------------------------------- [14:53:13] ylluminate(@ylluminate)::P ---------------------------------------------------------------------------------------------------- [14:53:22] Vais Salikhov(@vais):LOL ---------------------------------------------------------------------------------------------------- [14:53:24] ylluminate(@ylluminate):let's just use a white dot ---------------------------------------------------------------------------------------------------- [14:53:50] ylluminate(@ylluminate):(no outline, just a white dot... :shipit: ) ---------------------------------------------------------------------------------------------------- [14:58:42] Vais Salikhov(@vais):That's already taken - I'm using it for Diamond, my Opal implementation on top of Windows Scripting Host. ---------------------------------------------------------------------------------------------------- [14:59:23] Vais Salikhov(@vais):Anyway, long day, it's time for me to shutdown :zzz: Have fun with it! ---------------------------------------------------------------------------------------------------- [14:59:38] Elia Schito(@elia):good night! ---------------------------------------------------------------------------------------------------- [14:59:51] ylluminate(@ylluminate):lol, i thought that was "Glass" ---------------------------------------------------------------------------------------------------- [15:00:11] ylluminate(@ylluminate):sounds like it's pretty fragile... ;) night ---------------------------------------------------------------------------------------------------- [15:34:21] Forrest Chang(@fkchang):@ylluminate I like logo, w/the intentional ruby shape ---------------------------------------------------------------------------------------------------- [15:53:33] Christian Käser(@dfyx):@elia Did you see that the specs for opal-rails fail on travis? ---------------------------------------------------------------------------------------------------- [15:56:19] Elia Schito(@elia):@dfyx yes, I think it's a weird issue with travis' file system ---------------------------------------------------------------------------------------------------- [15:56:28] Christian Käser(@dfyx):Alright ---------------------------------------------------------------------------------------------------- [15:57:16] Christian Käser(@dfyx):Just saw it because my boss *finally* lets me migrate some of our web stuff to rails and what better way is there to start a new rails app than with opal on the front end? ---------------------------------------------------------------------------------------------------- [15:57:35] Elia Schito(@elia)::tada: ---------------------------------------------------------------------------------------------------- [15:58:31] Christian Käser(@dfyx):(Would have loved to use volt but I don't think it fits that specific application) ---------------------------------------------------------------------------------------------------- [16:54:18] Ryan Stout(@ryanstout):@adambeynon hey, how are you? Have you had any more thoughts about making opal-rspec wait on returned promises? ---------------------------------------------------------------------------------------------------- [16:57:16] Ryan Stout(@ryanstout):is there a way to do async/run_async in opal rspec for before/after right now? ---------------------------------------------------------------------------------------------------- [17:33:56] Mitch VanDuyn(@catmando):@ryanstout can you explain your opal-rspec question again? I am having what I think is a similar problem, so its something I have been thinking about as well. ---------------------------------------------------------------------------------------------------- [17:35:49] Ryan Stout(@ryanstout):@catmando basically, I have some stuff that returns a promise, and I want the it spec to wait until it resolves before continuing. (Since I setup .then blocks that run more expect's) ---------------------------------------------------------------------------------------------------- [17:35:51] Mitch VanDuyn(@catmando):@ylluminate how about putting a small standard red ruby symbol inside the current logo (instead of the triangle at the back) ---------------------------------------------------------------------------------------------------- [17:38:12] Mitch VanDuyn(@catmando):@ryanstout - **exactly** the same problem I having. For now I just have one giant spec with a bunch of `expects` inside that concluding in the final `async { expect ..`. ---------------------------------------------------------------------------------------------------- [17:41:20] Mitch VanDuyn(@catmando):@ryanstout this might be a quick easy fix: have each async block do a busy wait until the previous async block completes. Busy-wait normally bad, but acceptable in a test environment. ---------------------------------------------------------------------------------------------------- [17:41:42] Ryan Stout(@ryanstout):@catmando you can't busy wait in JS ---------------------------------------------------------------------------------------------------- [17:41:45] Mitch VanDuyn(@catmando):I am suggesting this function be added to aync ---------------------------------------------------------------------------------------------------- [17:41:48] Ryan Stout(@ryanstout):well, you can, but the other thing won't get done :-) ---------------------------------------------------------------------------------------------------- [17:41:52] Ryan Stout(@ryanstout):for (;;) {} ---------------------------------------------------------------------------------------------------- [17:42:12] Mitch VanDuyn(@catmando):perhaps I should have said "poll" ---------------------------------------------------------------------------------------------------- [17:42:40] Ryan Stout(@ryanstout):you can't do that either in this situation, because a setTimeout would move on to the next spec ---------------------------------------------------------------------------------------------------- [17:42:52] Ryan Stout(@ryanstout):afaik ---------------------------------------------------------------------------------------------------- [17:43:59] Mitch VanDuyn(@catmando):you would add the polling to the async block so yes it would "move on" but what you would actually create is a chain of async blocks that will run in order ---------------------------------------------------------------------------------------------------- [17:50:36] Mitch VanDuyn(@catmando):currently ```ruby async "test returns_a_promise" do returns_a_promise.then do async { expect ... } end end async "test returns_another_promise" do returns_another_promise.then do async { expect ... } end end ``` Today it may call returns_another_promise before returns_a_romise completes (just confirming the problem statement is correct) If each async test block just waits (heck probably doesn't need to poll) for the previous block finish its async test, then I think we are all set ---------------------------------------------------------------------------------------------------- [17:52:03] Mitch VanDuyn(@catmando):in fact we can add a optional parameter called `:test_chain` so that you can set up independent chains of tests ---------------------------------------------------------------------------------------------------- [17:55:11] Mitch VanDuyn(@catmando): ---------------------------------------------------------------------------------------------------- [17:56:31] Mitch VanDuyn(@catmando):```ruby async "test 1", test_chain: :chain_1 do # I will start right away end async "test 2", test_chain: :chain_2 do # I will also start right away end async "test 3" do # and I will also start right away end async "test 4" do # but I wont' start until test3 finishes end async "test 5", test_chain: :chain_1 do # and I won't start until test 1 finishes end ``` How about that? ---------------------------------------------------------------------------------------------------- [17:57:26] Mitch VanDuyn(@catmando):I think it can all be done today without updating opal-rspec just as a test: ---------------------------------------------------------------------------------------------------- ############################## [2015-05-30] ############################## [14:20:25] Vais Salikhov(@vais):Fun fact: Opal is now passing 5005 rubyspec examples :tada: ---------------------------------------------------------------------------------------------------- [16:03:37] Mitch VanDuyn(@catmando):Coolest! ---------------------------------------------------------------------------------------------------- [16:03:58] Mitch VanDuyn(@catmando):@vais 5005 out of?

For example, I don't need all of the CSSOM stuff and I want to make some of the more specialized things like `Browser::Event::DeviceProximity` opt-in vs loaded by default. It looks like it might take some restructuring of the base classes since it seems they know about their subclasses.

If I want events, though, I have to load all of the event types. ---------------------------------------------------------------------------------------------------- [17:08:41] meh.(@meh):jgaskins, splitting up the event handling code would be a pain in the ass, if I recall I tried last time and it came out really ugly ---------------------------------------------------------------------------------------------------- [17:09:24] meh.(@meh):jgaskins, but pull requests welcome if you figure out a way to make it not ugly as sin and cherry-pickable ---------------------------------------------------------------------------------------------------- [17:10:28] Jamie Gaskins(@jgaskins):@meh Totally, I have a few ideas I'll try out.

So your pull request would get rid of the need for this code I have? https://github.com/wedgeio/wedge/blob/master/lib/wedge/component.rb#L270-L294 ---------------------------------------------------------------------------------------------------- [02:36:32] Mitch VanDuyn(@catmando):does anybody know if class_eval is not fully implemented? Looking at the code it seems not, but there is no caveat in the documentation. Seems it will not work on a string, only if a block is supplied. ---------------------------------------------------------------------------------------------------- [05:24:06] Vais Salikhov(@vais):@catmando that' right, it's not. The reasoning behind this, AFAIK, is that a block can be used without needing the compiler at runtime, but a string would require one. ---------------------------------------------------------------------------------------------------- [12:56:59] Mitch VanDuyn(@catmando): Okay... I'm going to do a PR that will add the capability by requiring the parser. I.e. if parser is loaded then you get the full capability... ---------------------------------------------------------------------------------------------------- [13:54:58] Adam Beynon(@adambeynon):@catmando bare in mind, the compiler can only compile code that gets evaluated in the top/main context. It can’t take an optional context (object or class) to run against ---------------------------------------------------------------------------------------------------- [14:28:50] Mitch VanDuyn(@catmando):so far this seems to work, but only with limited testing :-) ```ruby class Module alias_method :old_class_eval, :class_eval def class_eval(*args, &block) #puts "new class eval has block?: #{!!block}" if !block cstring = "lambda {\n#{args[0]}\n}" #puts "building block from #{cstring}" #puts "testing Opal #{Opal.compile('puts "hi"')}" #puts compiled = Opal.compile(cstring) #puts "got some compiled stuff here #{compiled}" block = `eval(#{compiled})` #puts "got a nice block #{block}" end #puts "should be good to go #{block}" return old_class_eval(&block) end end ``` ---------------------------------------------------------------------------------------------------- [14:37:15] Mitch VanDuyn(@catmando):@adambeynon Should this work okay? Seems like it does... ---------------------------------------------------------------------------------------------------- [14:38:40] meh.(@meh):catmando, yeah, it's not a bad idea ---------------------------------------------------------------------------------------------------- [16:13:31] Adam Beynon(@adambeynon):@catmando yeah, but what Im saying is that any code inside that string will evaluate with ‘main’ as the self context. The class won’t be the value of `self` ---------------------------------------------------------------------------------------------------- [16:15:16] Mitch VanDuyn(@catmando):@adambeynon I thought wrapping it the lambda and then passing it back to the original class_eval would take care fo setting the context? ---------------------------------------------------------------------------------------------------- [16:16:34] Adam Beynon(@adambeynon):@catmando sorry ---------------------------------------------------------------------------------------------------- [16:16:36] Adam Beynon(@adambeynon):yes ---------------------------------------------------------------------------------------------------- [16:16:38] Adam Beynon(@adambeynon):you’re right ---------------------------------------------------------------------------------------------------- [16:16:53] Adam Beynon(@adambeynon):I missed that part :+1: ---------------------------------------------------------------------------------------------------- [16:27:24] Mitch VanDuyn(@catmando):no drama... the nice thing that i discovered is that if the parser is not present then compile returns nothing. So this method can just raise a nice error explaining that "require 'opal-parser' in order to use string blocks" ---------------------------------------------------------------------------------------------------- [16:29:21] Adam Beynon(@adambeynon):nice, yeap, sounds good to me :+1: ---------------------------------------------------------------------------------------------------- [16:43:32] Mitch VanDuyn(@catmando):hey has anybody seen this problem: Looks like you can't call super from self.included in a module. For example: ```ruby module ModuleToInclude def self.included(base) puts "about to call super" super puts "done with super" rescue Exception => e puts "whoops #{e}" end end class TheIncluder include ModuleToInclude end ``` in MRI you get: ```` about to call super done with super => TheIncluder ```` but in Opal you get ```` about to call super whoops ReferenceError: $ModuleToInclude is not defined ```` ---------------------------------------------------------------------------------------------------- [17:51:14] Mitch VanDuyn(@catmando):Folks - I'm full of obscure questions today! Is `catch symbol do ... end` not implemented? ---------------------------------------------------------------------------------------------------- [17:53:31] Mitch VanDuyn(@catmando):```ruby catch :foo do puts 'hi' end ``` fails with undefined method catch for main! ---------------------------------------------------------------------------------------------------- ############################## [2015-06-03] ############################## [00:28:27] Vais Salikhov(@vais):@catmando try/catch is not part of Opal AFAIK.

Its just odd because it seems like its in the parser and everything... ---------------------------------------------------------------------------------------------------- [00:38:34] Vais Salikhov(@vais):@catmando give it a shot! ---------------------------------------------------------------------------------------------------- [00:39:28] Mitch VanDuyn(@catmando):well already have - it is used in Acts As State Machine which I am getting working in Opal, so I already had to monkey patch it in :-) ---------------------------------------------------------------------------------------------------- [03:27:38] Vais Salikhov(@vais):@catmando PR plz ---------------------------------------------------------------------------------------------------- [08:02:27] Elia Schito(@elia):@catmando good to hear about throw/catch, I did a quick implementation some time ago but hadn't the time to finish it properly, looking forward to your PR : ) ---------------------------------------------------------------------------------------------------- [11:10:56] Mitch VanDuyn(@catmando):@elia mine will also be super quick and dirty ---------------------------------------------------------------------------------------------------- [11:12:07] Elia Schito(@elia)::shipit: please do it anyway, I'll add my version to the thread and hopefully we'll come up with something meaningful ---------------------------------------------------------------------------------------------------- [11:51:38] Vais Salikhov(@vais):@catmando what @elia said, just :shipit: :) ---------------------------------------------------------------------------------------------------- [13:18:28] Christian Käser(@dfyx):@elia I've just seen a really weird problem with opal-rails (might be a general rails/sprockets problem but I don't think so) ---------------------------------------------------------------------------------------------------- [13:21:16] Christian Käser(@dfyx):To reproduce: * Use rails 4.2.1 and opal-rails 0.7.0 * Run `rake assets:precompile` * Run rails in production * Visit the rails app in your browser * Stop rails and start it in development * Visit the rails app again ---------------------------------------------------------------------------------------------------- [13:21:23] Christian Käser(@dfyx):Result: "Opal already loaded.

I assume I'll need to wrap the plugins in someway (using native, or a wrapper class/module). It's seems straight forward looking at opal-jquery's source how it's wrapping jQuery, but for some reason I'm not grasping how to do it with a plugin. Can anyone point me in the right direction? Or suggest some existing jQuery plugin wrappers at which I could look? ---------------------------------------------------------------------------------------------------- [15:37:30] Adam Beynon(@adambeynon):@ajjahn if it is a simple method, which takes simple parameters you can use the expose method ---------------------------------------------------------------------------------------------------- [15:37:37] Adam Beynon(@adambeynon):e.g., with bootstrap’s modal() plugin: ---------------------------------------------------------------------------------------------------- [15:37:44] Adam Beynon(@adambeynon):`Element.expose :modal` ---------------------------------------------------------------------------------------------------- [15:38:04] Adam Beynon(@adambeynon):that assumes we can pass parameters which can be handled directly, e.g. strings, numbers etc ---------------------------------------------------------------------------------------------------- [15:38:08] Adam Beynon(@adambeynon):or no args at all ---------------------------------------------------------------------------------------------------- [15:53:58] Adam Jahn(@ajjahn):@adambeynon Intersting; I'll have a look at that! One road I traveled down for more complex methods was to create a module that implements the plugin's method(s) by shelling out to JS and then including it in the Element class: `Element.send(:include, PluginModule)`. Works, but I wouldn't know if there is a better way. ---------------------------------------------------------------------------------------------------- [17:33:52] BrandonMathis(@BrandonMathis):@RickCarlino We promoted one of our devs to a Volt developer ---------------------------------------------------------------------------------------------------- [20:24:25] Rick Carlino(@RickCarlino):@BrandonMathis I saw that.

In my mind, the subject of Ruby's demise has been beaten to death already. The definitive piece to me was Jeff Atwood's http://blog.codinghorror.com/why-ruby from 2013 (!): > Ruby isn't cool any more. Yeah, you heard me. It's not cool to write Ruby code any more. All the cool people moved on to slinging Scala and Node.js years ago. Our project isn't cool, it's just a bunch of boring old Ruby code. Personally, I'm thrilled that Ruby is now mature enough that the community no longer needs to bother with the pretense of being the coolest kid on the block. That means the rest of us who just like to Get Shit Done can roll up our sleeves and focus on the mission of building stuff with our peers rather than frantically running around trying to suss out the next shiny thing. That said, if you feel strongly about Ruby (Opal) advocacy, they could use your help over at https://gitter.im/AstonJ/Opal-and-Co--Strategies cc @AstonJ ---------------------------------------------------------------------------------------------------- [02:36:40] Ryan Stout(@ryanstout):@meh is the "a promise has already been chained" exception standard behavior in A+?

(@catmando, btw, [this](https://github.com/catprintlabs/opal/blob/module-class-eval-compilation/opal/corelib/module.rb#L378) does not seem to work in [this](https://github.com/vais/opal/blob/benchmark-dispatch/benchmark/bm_dispatch_code_gen.rb#L26) case.)

You specify it as the main file, so either you have your own copy of it, or you want to access the sprockets_runner in opal-rspec gem, which means you'll have to add it to opal's load path so it finds it as you've specified it (or specify it differently) ---------------------------------------------------------------------------------------------------- [17:27:48] Mitch VanDuyn(@catmando):@fkchang head is spinning... I'll take any suggestion. Right now I can get rid of that error (sprockets runner not found) by requiring 'opal-rspec' but perhaps that is what is causing the other breakages. I just don't fully follow your suggestion, I got that I have to include sprockets_runner.js someplace, but where exactly, and where do I get it? ---------------------------------------------------------------------------------------------------- [17:27:56] Mitch VanDuyn(@catmando):Sorry to be dim :-) ---------------------------------------------------------------------------------------------------- [17:28:51] Mitch VanDuyn(@catmando):I mean I see a "spec_runner.js" in opal_spec/vendor... ---------------------------------------------------------------------------------------------------- [17:30:44] Mitch VanDuyn(@catmando):I see the .rb.erb file, so I guess I can bodge this up someway... ---------------------------------------------------------------------------------------------------- [18:37:39] Mitch VanDuyn(@catmando):Hi ---------------------------------------------------------------------------------------------------- [19:54:38] Forrest Chang(@fkchang):@catmando ``` s.main = 'opal/rspec/sprockets_runner'``` specifies the file for Opal::Server to run - somehow the you need the spec files, the class files, need to get loaded and rspec needs to get kicked off. This can be done in a number of ways, all via the code file run, or in the index_path file or some combination of both (i.e. load the files in the index, kick off the suite in the js.rb). That being said, IIRC, there are sprocket_runners in both opal-rspec and opal-rails (at least to facilitate being able to run a rake task and to hit the /opal_spec in the app itself, you can imagine the 2 end points would be different). Since you are not using opal-rails, I would have to assume the sprockets_runner.js.rb you want to run is the one in opal-rspec gem. Re: your error I can't tell if```uninitialized constant Object::RSpec``` is the problem, but I would suspect that maybe you are missing an opal-rspec reference. It might be one of those cases where you need to require it on the server side for 1 thing, and on the client for the other half ---------------------------------------------------------------------------------------------------- [19:57:55] Mitch VanDuyn(@catmando):@fkchang. Hey thanks a lot. Meanwhile I looked at another gem source I have that DOES have seem to work okay (opal-aasm) and I see that the developer of react.rb has some things I don't understand in the way files are required. I think that may be causing the problem. Thanks again, I'll let everybody know what I figure out for future reference. ---------------------------------------------------------------------------------------------------- [20:18:41] Mitch VanDuyn(@catmando):@/all So can somebody explain why (and how it works) I see opal gem structures like this: top-level ``` top-level | - lib | - opal | - opal-gemname.rb | - opal | - opal | - opal-remname.rb ``` Am I right in guessing that the code in the lib directory only runs on the server, while in outer opal directory is common? I have been doing an ```ruby if RUBY_ENGINE = = 'opal' ... else ... end ``` to achieve this, but I am looking at some other gems it does not have the RUBY_ENGINE == 'opal' anywhere, but yet I am pretty sure some of these gems (like opal-rspec) must have some differences between server and client. I think this is at this is related to why I can't get react.rb to run opal-rspec. I have an older version of react.rb that has the `if RUBY_ENGINE... ` and it works fine. Any help appreciated! ---------------------------------------------------------------------------------------------------- [20:53:57] Mitch VanDuyn(@catmando):figured it out... you have to use latest released opal-rspec with latest released opal. Gemfile was locked at opal-rspec 3x... ---------------------------------------------------------------------------------------------------- [21:05:20] Jared White(@jaredcwhite):@catmando the lib ... opal structure is actually an older convention. Using the if conditional within /lib alone is newer and preferred AFAIK. ---------------------------------------------------------------------------------------------------- ############################## [2015-06-10] ############################## [22:54:45] Srikanth Kuppuswamy(@Hospira-MedNet):direct call from .JS file ---------------------------------------------------------------------------------------------------- [22:56:59] Srikanth Kuppuswamy(@Hospira-MedNet):@elia or anyone plz help me out on this ---------------------------------------------------------------------------------------------------- [01:26:24] Forrest Chang(@fkchang):@jaredcwhite submitted my opalist entry ---------------------------------------------------------------------------------------------------- [09:07:39] Christian Käser(@dfyx):@elia I found some other weird behavior with opal-jquery ---------------------------------------------------------------------------------------------------- [09:08:46] Christian Käser(@dfyx):Assume I have the following html: `...` ---------------------------------------------------------------------------------------------------- [09:09:28] Christian Käser(@dfyx):Now I run `Element.find('#foobar').data('some-object')` ---------------------------------------------------------------------------------------------------- [09:10:34] Christian Käser(@dfyx):jQuery parses the JSON and returns a JS object. opal-jquery doesn't wrap this object and just returns it ---------------------------------------------------------------------------------------------------- [09:11:24] Adam Beynon(@adambeynon):@dfyx yeah, its a bug. until now Element#data assumed it was either a string or numeric - it needs to check for js objects and wrap them in a hash ---------------------------------------------------------------------------------------------------- [09:12:07] Christian Käser(@dfyx):@adambeynon What's the best way to wrap an object in a hash?

But i am getting some exceptions ---------------------------------------------------------------------------------------------------- [07:02:44] Forrest Chang(@fkchang):@adambeynon @meh @elia @vais shouldn't an instance Native::Object return something other than nil for methods?

(just to help me understand) ---------------------------------------------------------------------------------------------------- [08:17:58] Srikanth Kuppuswamy(@Hospira-MedNet):@fkchang let me know whether am i compiling correctly. If not , Please let me know on how to compile class Foo ---------------------------------------------------------------------------------------------------- [12:11:41] Vais Salikhov(@vais):@adambeynon @elia guys, with arity check enabled (which is how specs are running), the following fails with an `ArgumentError`, `wrong number of arguments(1 for 0)` ```ruby def test puts 'ok' end a = nil test(*a) ``` But this works on MRI just fine. I think splat with a `nil` is a special case. Any idea where I could begin fixing this? I need this to work to pass some new rubyspecs... ---------------------------------------------------------------------------------------------------- [12:25:32] Srikanth Kuppuswamy(@Hospira-MedNet):can anyone give me some suggestions on my question plzz ---------------------------------------------------------------------------------------------------- [12:31:45] Vais Salikhov(@vais):@Hospira-MedNet in your stackoverflow question it looks like you are answering your own question. It's not clear what exactly is your question?? ---------------------------------------------------------------------------------------------------- [12:42:34] Srikanth Kuppuswamy(@Hospira-MedNet):@vais my question is how i can call ruby method in my protractor tests (.JS file) ---------------------------------------------------------------------------------------------------- [12:43:21] Srikanth Kuppuswamy(@Hospira-MedNet):@fkchang told me that you need to compile first.. so i called like Opal.compile(Foo) in my ruby file but i got some exceptions ---------------------------------------------------------------------------------------------------- [12:51:23] Vais Salikhov(@vais):@Hospira-MedNet the easiest way for you to compile `file.rb` into `file.js` is to write this on the command line: `opal -c file.rb > file.js` Now you can include `file.js` into your html page using a script tag, like any other javascript file. Make sense? ---------------------------------------------------------------------------------------------------- [12:59:21] Srikanth Kuppuswamy(@Hospira-MedNet):i did i am getting other general opal related stuff with at the end our class name is now converted into function name ---------------------------------------------------------------------------------------------------- [12:59:53] Srikanth Kuppuswamy(@Hospira-MedNet):as you said using script tag we can call this .js file ---------------------------------------------------------------------------------------------------- [13:00:24] Srikanth Kuppuswamy(@Hospira-MedNet):so i can call directly like this Opal.Foo.$new().$bar(); in .JS file am i right? ---------------------------------------------------------------------------------------------------- [13:16:41] Vais Salikhov(@vais):@Hospira-MedNet yep, what you get in that .js file is all of Opal compiled to javascript + your ruby compiled to javascript. Now if you include this file into your page, other javascript included after this file should be able to call into your ruby-compiled-to-js code. Hope this helps! ---------------------------------------------------------------------------------------------------- [14:34:37] CJ Lazell(@cj):@vais found another bug to do with procs ---------------------------------------------------------------------------------------------------- [14:35:54] CJ Lazell(@cj):https://github.com/opal/opal/issues/932 ---------------------------------------------------------------------------------------------------- [14:36:27] CJ Lazell(@cj):I created an opalrb gist with a refined example ---------------------------------------------------------------------------------------------------- [15:30:33] Vais Salikhov(@vais):@cj wait, that's the refined example?!

Every one use it ? Thanks ---------------------------------------------------------------------------------------------------- [22:08:13] Michał Kalbarczyk(@fazibear):@jgaskins, any clues ? ---------------------------------------------------------------------------------------------------- [22:15:20] Mitch VanDuyn(@catmando):I am trying to make a directory in rails (lets call it app/shared) that will contain ruby code that rails will find on the server (I think this is the easy part) but also that will get compiled and downloaded with the assets. Any clues? (anybody else?) ---------------------------------------------------------------------------------------------------- [22:17:48] Michał Kalbarczyk(@fazibear):@catmando maybe that will help ``` # config/initializers/opal.rb Rails.application.config.assets.paths << Rails.root.join('app', ’shared').to_s ``` ---------------------------------------------------------------------------------------------------- [22:25:07] Mitch VanDuyn(@catmando):@fazibear - that was it! works great. thanks ---------------------------------------------------------------------------------------------------- [22:33:22] Mitch VanDuyn(@catmando):but now the problem is (not a big problem) I want to just pull in all the files in that shared directory without requiring them. I would like to keep the require_tree directive in the assets folder, but I don't think there is a way. I guess will have to add a file in the shared directory called shared.rb that just has a require_tree "." or something? ---------------------------------------------------------------------------------------------------- [22:46:21] Forrest Chang(@fkchang):@catmando don't have time to write it now, but I've been meaning to blog about how we approached the shared code in our production app ---------------------------------------------------------------------------------------------------- [22:47:07] Mitch VanDuyn(@catmando):@fkchang - any quick hints? We are right there and I don't want to reinvent the wheel. ---------------------------------------------------------------------------------------------------- [22:49:07] Forrest Chang(@fkchang):there were some issues, we had to resolve, but in short, we made a lib/client_and_server directory that we softlinked into app/assets/javascripts ---------------------------------------------------------------------------------------------------- [22:49:26] Forrest Chang(@fkchang):we did have some load order issues that we had to specifically specify require order, which may or may not hit you ---------------------------------------------------------------------------------------------------- [22:50:23] Mitch VanDuyn(@catmando):So far I am setting up a directory shared, which will contain ruby code that will get included in the server as well as the client... So for works okay, except I wanted to do this: ```ruby class Jobs # bunch of stuff that only is relevant to the server end ``` and in the shared directory ```ruby class Jobs # stuff related to both client and server end ``` The only problem is that rails will only find one (I think) so one has to require the other... not a big deal I guess ---------------------------------------------------------------------------------------------------- [22:51:22] Mitch VanDuyn(@catmando):why did you go with the softlink approach and not just a directory at the top level (i.e. app/client_and_server) ---------------------------------------------------------------------------------------------------- [22:52:13] Forrest Chang(@fkchang):I would put the common code in the lib/client_and_server dir, and the extend the class respectively in the appropriate server/link ---------------------------------------------------------------------------------------------------- [22:53:39] Forrest Chang(@fkchang):re softlink, I guess we could've done that. We messed around w/autoloader no autoloading on both front and back end for various things, ended up with something different than we started with ---------------------------------------------------------------------------------------------------- [22:53:49] Forrest Chang(@fkchang):could've worked w/the toplevel dir ---------------------------------------------------------------------------------------------------- [22:54:28] Forrest Chang(@fkchang):I'd be curious to what @elia and @adambeynon have done, they've deployed the most opal rails apps of anyone ---------------------------------------------------------------------------------------------------- [22:57:09] Mitch VanDuyn(@catmando):@fkchang - yeah I guess the extend will be okay, but it would be nice to just have it be automagic ---------------------------------------------------------------------------------------------------- [23:13:15] Forrest Chang(@fkchang):u could check the ruby engine for opal in a single file ---------------------------------------------------------------------------------------------------- [23:13:32] Forrest Chang(@fkchang):not certain I like the cleanliness of that, but it'd work w/o extending the classes ---------------------------------------------------------------------------------------------------- ############################## [2015-06-12] ############################## [07:48:59] Elia Schito(@elia):@kofno https://gist.github.com/kofno/2762bcc615ce7440b7f0#comment-1472177 ---------------------------------------------------------------------------------------------------- [09:23:53] Keith Salisbury(@globalkeith):Hi all, I'm doing a presentation to my company at lunchtime about Opal and I've compiled a gist with all the links I can find to useful stuff - if you have another useful link please can you let me know.... https://gist.github.com/globalkeith/fd1e3c7144dc67f21463 ---------------------------------------------------------------------------------------------------- [09:24:22] Keith Salisbury(@globalkeith):Sorry I didn't realise it would add it all here.... ---------------------------------------------------------------------------------------------------- [13:47:13] Gabriel Rios(@gabrielrios):Is there any doc on native inheritance?

YAY!!! :clap: I do have one concern which I mentioned here: https://github.com/opal/opal-rails/issues/49#issuecomment-113186052 It seems there's no more require_tree for including many Opal files in a folder. My homegrown front-end framework expects there to be a variable number of files in each of the main folders (controllers, views, etc.), and it seems like a big pain to have to remember to go in and explicitly add require 'controller/foo' type statements for every single one. ---------------------------------------------------------------------------------------------------- [15:11:50] Elia Schito(@elia):@jaredcwhite see my answer, but basically you just have to use require_tree from opal instead of using the sprockets magic comment ---------------------------------------------------------------------------------------------------- [15:33:42] Mitch VanDuyn(@catmando):Does 0.8 still require sprockets 3.x? (Q1) Q2 - is there a from_n or some other concept like that, where I can add a method to a class that will convert from a native object to an instance of that class? Obviously I can do a JSON parse, and then allow the classes .new method to accept a hash, but it seems like there should be a standard way of announcing the intention ---------------------------------------------------------------------------------------------------- [15:44:30] Elia Schito(@elia):Q1 - yes, sorry Q2 - no, but it's a good idea, yet we should first look at how Ruby handles this kind of things first to see if there's some standard we can adhere to ---------------------------------------------------------------------------------------------------- [15:44:41] Elia Schito(@elia):cc @meh ^^ ---------------------------------------------------------------------------------------------------- [16:09:18] Forrest Chang(@fkchang):@RickCarlino I had that problem, on 6.2, and got around it. Don't remember how, search the irc, @meh had to help me out on it, IIRC ---------------------------------------------------------------------------------------------------- [16:17:27] Rick Carlino(@RickCarlino):Ah, no worries, I ended up just using Opal-JQ in the meantime ---------------------------------------------------------------------------------------------------- [18:05:06] Mitch VanDuyn(@catmando):@elia - that's what I was thinking (re from_native) I mean you could just have .new check to see if the incoming param is native, in which case do the conversion. Hmmm... maybe that is a good enough convention. ---------------------------------------------------------------------------------------------------- [19:48:08] Mitch VanDuyn(@catmando):So what is the canonical way to check if an object is native or not? ---------------------------------------------------------------------------------------------------- [20:03:31] Elia Schito(@elia):Hash.new word that way ---------------------------------------------------------------------------------------------------- [20:04:21] Elia Schito(@elia):and native.rb adds Kernel#native? iirc ---------------------------------------------------------------------------------------------------- [20:47:07] Ryan Stout(@ryanstout):how do I get a javascript date object into an opal time object? ---------------------------------------------------------------------------------------------------- [20:52:57] Ryan Stout(@ryanstout):nevermind, figured it out ---------------------------------------------------------------------------------------------------- [21:14:16] ylluminate(@ylluminate):@adambeynon thank you for taking action on those "issues" gone wild. ---------------------------------------------------------------------------------------------------- ############################## [2015-06-19] ############################## [16:52:22] meh.(@meh):but many methods come from the stdlib ---------------------------------------------------------------------------------------------------- [16:52:38] meh.(@meh):no idea why it was designed like that, but it's how it is ---------------------------------------------------------------------------------------------------- [16:56:46] Todd J Russell(@comexpressao):in the browser console I tried: ---------------------------------------------------------------------------------------------------- [16:56:49] Todd J Russell(@comexpressao):Opal.Date.$parse(Opal.Time.$now()) ---------------------------------------------------------------------------------------------------- [16:57:03] Todd J Russell(@comexpressao):Uncaught TypeError: Cannot read property '1' of null ---------------------------------------------------------------------------------------------------- [16:57:08] Todd J Russell(@comexpressao):oh well :-( ---------------------------------------------------------------------------------------------------- [16:57:34] meh.(@meh):comexpressao, yeah, that method is in the stdlib, you have to `require 'date'` to access it ---------------------------------------------------------------------------------------------------- [16:57:41] meh.(@meh):and IIRC the try doesn't support requires ---------------------------------------------------------------------------------------------------- [16:57:53] meh.(@meh):it will work when using Opal normally ---------------------------------------------------------------------------------------------------- [16:58:03] Todd J Russell(@comexpressao):we got it... the above was missing to_s... now works ---------------------------------------------------------------------------------------------------- [16:58:08] Todd J Russell(@comexpressao):yeah! ---------------------------------------------------------------------------------------------------- [16:59:48] Todd J Russell(@comexpressao):Thanks for all the help and input ---------------------------------------------------------------------------------------------------- [17:01:02] meh.(@meh):np ---------------------------------------------------------------------------------------------------- [17:04:59] Michał Kalbarczyk(@fazibear):is there any estmined date for 0.8 release ? ---------------------------------------------------------------------------------------------------- [18:08:25] Jared White(@jaredcwhite):@ylluminate @dfyx Yeah that WebAssembly stuff sounds fantastic. If some folks have been hesitant to use a compile-to-JS language because of a fear of leaky abstractions or some other perceived issues that compel them to stick with raw JS, this kind of thing could really be the tipping point. It turns the browser into a lower-level runtime that can execute code from a theoretically infinite variety of higher-level languages. What remains to be seen is what kind of language features end up really being supported. We benefit from the fact that most of the cool stuff Ruby does can actually be implemented on top of JS. But what about a language that has some kind of bizarre syntax/state/execution flow/data processing/whatever feature that WebAssembly simply doesn't support? I guess I will need to read up on the details as they come out... ---------------------------------------------------------------------------------------------------- [18:11:39] ylluminate(@ylluminate):well, i guess it depends on how close it comes to an assembly level implementation. everything runs atop a relatively simplistic set of rules when you look at it from a true asm perspective and if they're able to achieve that, then probably sky's the limits ---------------------------------------------------------------------------------------------------- [19:49:35] Elia Schito(@elia):@fazibear it's almost ready but there's some stuff going on now and I don't think a release will happen until it's settled ---------------------------------------------------------------------------------------------------- [21:58:45] Forrest Chang(@fkchang):@catmando I just now remembered why we did the client_and_server softlink the way we did. I wanted an explicit 'client_and_server' in the opal requires to indicate that the code was shared and not client only ---------------------------------------------------------------------------------------------------- [22:11:38] Mitch VanDuyn(@catmando):@fkchang thanks for that info ---------------------------------------------------------------------------------------------------- [03:00:05] ylluminate(@ylluminate):heads up @all http://techcrunch.com/2015/06/17/google-microsoft-mozilla-and-others-team-up-to-launch-webassembly-a-new-binary-format-for-the-web/ ---------------------------------------------------------------------------------------------------- [03:05:12] ylluminate(@ylluminate):> "The team notes that the idea here is not to replace JavaScript, by the way, but to allow many more languages to be compiled for the Web. Indeed, chances are that both JavaScript and WebAssembly will be used side-by-side and some parts of the application may use WebAssembly modules (animation, visualization, compression, etc.), while the user interface will still be mostly written in JavaScript, for example." ---------------------------------------------------------------------------------------------------- [15:10:25] Christian Käser(@dfyx):@ylluminate Sounds really promising. In fact I'm reading the design document right now ---------------------------------------------------------------------------------------------------- [15:10:32] Christian Käser(@dfyx):https://github.com/WebAssembly/design ---------------------------------------------------------------------------------------------------- [15:47:28] Todd J Russell(@comexpressao):Hey guys, I'm attempting to include the timeliness gem with no success.

I.e. each file is named after the directory name in RubySpec and contains the failing specs for all the files in that directory. It's a bit of a dumping ground right now. It's kinda organized by "topic", which makes it not quite straight-forward if you want to get a clear picture of what exactly is unsupported, or where to put a new failing item. Or to revise things down the road. It's a bit of work, so before I do, I'd like to know if there are any objections. ---------------------------------------------------------------------------------------------------- [16:31:48] meh.(@meh):vais, I'm fine with that, it was just a dumping ground, I think we didn't even have sections at the beginning ---------------------------------------------------------------------------------------------------- [16:33:24] Todd J Russell(@comexpressao):is DateTime implemented?

Got your submission! Issue's going out in the morning. Good night folks :) ---------------------------------------------------------------------------------------------------- [05:44:38] Adam Beynon(@adambeynon):@fkchang Array, String etc which are just instances of the JavaScript equivalents. Objects which we just use and extend rather than wrapping ---------------------------------------------------------------------------------------------------- [16:19:28] Forrest Chang(@fkchang):@adambeynon ok, so when opal-jquery says that Element is a toll free bridged class by doing ---------------------------------------------------------------------------------------------------- [16:20:18] Forrest Chang(@fkchang):```ruby class Element < `#{JQUERY_CLASS.to_n}` ``` What it means is that you're extending JQUERY_CLASS via the above line? ---------------------------------------------------------------------------------------------------- [16:21:17] Adam Beynon(@adambeynon):@fkchang Yeap. If you pass a javascript class (i.e. just a Function) as a superclass, then we extend the function prototype and make it toll free ---------------------------------------------------------------------------------------------------- [16:21:27] Adam Beynon(@adambeynon):We then mix in all methods from Object and Kernel ---------------------------------------------------------------------------------------------------- [16:21:39] Adam Beynon(@adambeynon):and any future method defined on Object and Kernel get added to it as well ---------------------------------------------------------------------------------------------------- [16:22:30] Adam Beynon(@adambeynon):but do bare in mind, we also treat it as a method_missing target, so we adds all those dummy methods to its prototype so method_missing works on it like any other ruby object ---------------------------------------------------------------------------------------------------- [16:24:25] Forrest Chang(@fkchang):@adambeynon ok, so side effect is I can now call $ opal methods off of $ in js ---------------------------------------------------------------------------------------------------- [16:25:03] Elia Schito(@elia):I do that all the time ---------------------------------------------------------------------------------------------------- [16:25:24] Forrest Chang(@fkchang):interesting ---------------------------------------------------------------------------------------------------- [16:37:47] Forrest Chang(@fkchang):while I have @adambeynon and @elia online, how is $$ defined? because ```ruby $$ == `window` # true $$[:jQuery] # works `window`[:jQuery] # fails no method [] $$ != Native(`window`) # true, but Native(`window`)[:jQuery] works ``` ---------------------------------------------------------------------------------------------------- [16:38:46] Elia Schito(@elia):$$ is ```Native(`Opal.global`)``` ---------------------------------------------------------------------------------------------------- [16:38:57] Elia Schito(@elia):which in the browser is window of course ---------------------------------------------------------------------------------------------------- [16:39:16] Forrest Chang(@fkchang):also what terminology do we use for what's returned by x strings, I want to say native, but it's not the same as what's returned by Native() ---------------------------------------------------------------------------------------------------- [16:39:30] Elia Schito(@elia):I think ```$$ != Native(`window`)``` is a bug ---------------------------------------------------------------------------------------------------- [16:53:21] meh.(@meh):sounds like a bug indeed ---------------------------------------------------------------------------------------------------- [16:53:23] meh.(@meh):gonna fix that ---------------------------------------------------------------------------------------------------- [16:54:57] Rick Carlino(@RickCarlino):So `$$` is an interface to native JS functions?

That's why I'm working on implementing these things in Opal now, hoping to figure it out once and for all, but it's been a slog :sweat_smile: ---------------------------------------------------------------------------------------------------- [02:00:33] Ryan Stout(@ryanstout):@vais yea, I think there's one (or probably two) too many date/time classes in ruby :-) ---------------------------------------------------------------------------------------------------- [02:00:50] Ryan Stout(@ryanstout):@vais thanks for the hard work, let me know if there's something I can help with. ---------------------------------------------------------------------------------------------------- [02:06:34] Vais Salikhov(@vais):Thanks @ryanstout. Right now, if you `require 'time'`, you can do `Time.parse`, which simply calls `Date.parse`, whose implementation is just two lines of code that uses this regex: `/^(\d*)-(\d*)-(\d*)/`. Leaves much to be desired to say the least. You may not want to lean too heavily on it at this time. ---------------------------------------------------------------------------------------------------- [02:14:49] Ryan Stout(@ryanstout):@vais no worries. Yea, I figured too you probably don't want all of the parse logic in corelib because its probably huge (file size wise :-) ---------------------------------------------------------------------------------------------------- [02:30:23] George Plymale II(@ylluminarious):some weird problems with native inheritance: http://cl.ly/400W070w1z2F ---------------------------------------------------------------------------------------------------- [02:30:42] George Plymale II(@ylluminarious):@elia @meh @adambeynon got any suggestions / input? ---------------------------------------------------------------------------------------------------- [02:31:28] Vais Salikhov(@vais):@ryanstout right, but it wouldn't go into corelib's Time, it would go into stdlib Date or Time, which you'd then `require` if you need it, so file size should not be an issue. ---------------------------------------------------------------------------------------------------- [02:31:59] Ryan Stout(@ryanstout):cool ---------------------------------------------------------------------------------------------------- [16:09:21] Forrest Chang(@fkchang):@ylluminarious in 'toll free bridging' you need to redefine Klass.new because the original javascript constructor maps to Ruby's allocate (http://seejohncode.com/2012/03/16/ruby-class-allocate/) ---------------------------------------------------------------------------------------------------- [17:55:19] Nathan Hopkins(@hopsoft):Is it possible to use opal + react-rails + react.rb? I keep getting `parse error on value "Unobtrusive" (tCONSTANT) :react_ujs:3` when the pipeline tries to load `react_ujs.js.erb`. Is opal is attempting to process this file because it's erb? ---------------------------------------------------------------------------------------------------- [17:59:18] Nathan Hopkins(@hopsoft):Here is the start of the file it dies on: ``` /*globals React, Turbolinks*/ // Unobtrusive scripting adapter for React ;(function(document, window) { // jQuery is optional. Use it to support legacy browsers. var $ = (typeof window.jQuery !== 'undefined') && window.jQuery; ``` ---------------------------------------------------------------------------------------------------- [18:36:03] Mitch VanDuyn(@catmando):@hopsoft - We have been using opal + react-rails + react.rb. I don't remember ever seeing that problem (but I saw so many :-)... I could get together with you and try to figure this out. Let me know ---------------------------------------------------------------------------------------------------- [18:38:34] Nathan Hopkins(@hopsoft):@catmando now that you have some battle scars, would you choose this path again? ---------------------------------------------------------------------------------------------------- [18:38:48] Mitch VanDuyn(@catmando):Experts! I have a loading twist here I just can't work out: I have opal running on the server (in rubyracer under react-rails) + ruby code on server + opal in browser. The problem I just ran into is need opal-jquery on the browser, but not (obviously) on the opal server side. This is all going into a gem, so its a bit unclear how I can require opal-jquery only if the browser is loading ---------------------------------------------------------------------------------------------------- [18:39:06] Mitch VanDuyn(@catmando):@hopsoft - I am betting my whole company on it :-) ---------------------------------------------------------------------------------------------------- [18:40:31] Nathan Hopkins(@hopsoft):@catmando Thanks. I'll reach out to you in a bit if I can't get past it. ---------------------------------------------------------------------------------------------------- [18:40:35] Mitch VanDuyn(@catmando):@hopsoft - but we not using JSX at all. Its pure ruby, with a highly modified version of react.rb. My developers are really loving it. ---------------------------------------------------------------------------------------------------- [18:41:36] Mitch VanDuyn(@catmando):@hopsoft - yeah just ping me. I'll try to keep one eye on gitter ---------------------------------------------------------------------------------------------------- [19:01:07] Mitch VanDuyn(@catmando):regarding my request for conditionally loading: I just did this which seems to work: ```ruby if RUBY_ENGINE == 'opal' if `typeof window.ReactiveRecordCache == 'undefined'` require 'opal-jquery' end end ``` where `window.ReactiveRecordCache ` is a variable defined only if running opal on the server This works, but I was SURE that i saw warnings when I was getting the AASM gem working whenever that gem did conditional requires. ---------------------------------------------------------------------------------------------------- [21:27:04] Elia Schito(@elia):@catmando that's the way to go ---------------------------------------------------------------------------------------------------- [21:52:05] Elia Schito(@elia):warnings are printed for dynamic requires, which can't be clearly inferred by the compiler ---------------------------------------------------------------------------------------------------- ############################## [2015-06-27] ############################## [00:26:22] Mitch VanDuyn(@catmando):Cool... ---------------------------------------------------------------------------------------------------- [00:27:05] Mitch VanDuyn(@catmando):I assume that checking predefined constants etc should work as well.

Maybe approach 2 to start, giving the capability now, and then down the road doing approach 1, but that would be reinforced more if I could see another use for this functionality Thoughts, tips? Thanks ---------------------------------------------------------------------------------------------------- ############################## [2015-06-30] ############################## [21:40:13] Mitch VanDuyn(@catmando):@ktec, am swamped right now, but if I get I chance I will have a look... ---------------------------------------------------------------------------------------------------- [21:40:17] Elia Schito(@elia):@ktec can you post any of the errors just to start from something? ---------------------------------------------------------------------------------------------------- [21:44:01] Forrest Chang(@fkchang):@ktec I looked at your repo, but I would need more specifics ---------------------------------------------------------------------------------------------------- [21:47:18] Keith(@ktec):hi guys, so the first problem is the inheritance, I would like to use the benefits of ruby and implement the base.rb class here https://github.com/globalkeith/opal-pixi/blob/master/lib/opal/pixi/base.rb and include it, as an example here: https://github.com/globalkeith/opal-pixi/blob/master/lib/opal/pixi/container.rb however when I include it, it runs the x-string stuff, but the instance methods are no longer available. ---------------------------------------------------------------------------------------------------- [21:49:20] Elia Schito(@elia):@ktec maybe you're overwriting some local vars, eval is dangerous as always :) ---------------------------------------------------------------------------------------------------- [21:49:56] Keith(@ktec):If i can use `include PIXI::Base` I can get rid of the x-strings in all the classes. Then i can start to implement some metaprogramming stuff like method missing. I couldn't get the x-string to interpolate without doing it like that ---------------------------------------------------------------------------------------------------- [21:50:09] Elia Schito(@elia):also beware that in opal 0.7 _proto and friends are all preceded by `$$`, e.g. `$$proto` ---------------------------------------------------------------------------------------------------- [21:50:39] Keith(@ktec):perhaps there's a problem with the way the project is set up, thats really why i was asking if someone could take a look and point me in the right direction ---------------------------------------------------------------------------------------------------- [21:50:39] Mitch VanDuyn(@catmando):@ktec, I am missing where you are doing teh include? ---------------------------------------------------------------------------------------------------- [21:51:23] Keith(@ktec):at the moment the includes are all commented out (all includes are in these classes https://github.com/globalkeith/opal-pixi/tree/master/lib/opal/pixi ---------------------------------------------------------------------------------------------------- [21:51:38] Keith(@ktec):i want to use `base.rb` ---------------------------------------------------------------------------------------------------- [21:54:40] Keith(@ktec):i've set up the https://github.com/globalkeith/opal-pixi/tree/master/demo directory to run the example, which uses the gem code in https://github.com/globalkeith/opal-pixi/tree/master/lib ---------------------------------------------------------------------------------------------------- [21:55:06] ylluminate(@ylluminate):hey @ktec, pop on over here: https://gitter.im/orbitalimpact/opal-pixi ---------------------------------------------------------------------------------------------------- [21:55:17] Keith(@ktec):thats where i started ---------------------------------------------------------------------------------------------------- [00:04:09] Forrest Chang(@fkchang):[![Pasted_Image_6_29_15__5_03_PM.png](https://files.gitter.im/opal/opal/cCNy/thumb/Pasted_Image_6_29_15__5_03_PM.png)](https://files.gitter.im/opal/opal/cCNy/Pasted_Image_6_29_15__5_03_PM.png) ---------------------------------------------------------------------------------------------------- [00:04:28] Forrest Chang(@fkchang):I need some styling help, this is what I've got but I don't think it scales out right ---------------------------------------------------------------------------------------------------- [04:33:49] Jared White(@jaredcwhite):I'm planning on writing an article with example code on how to use design patterns in rolling your own front-end framework with Opal. Anyone have any suggestions for what to focus on? Any pain points? I want to go beyond binding a method to a button click or rendering a list of li tags. That's obvious stuff. :) ---------------------------------------------------------------------------------------------------- [13:48:28] ylluminate(@ylluminate):@fkchang you know, i've always thought a pull request or fork of jsbin would be an incredibly useful approach along with an integration of the repl. it would definitely give opal more exposure to boot if it were integrated into the core. ---------------------------------------------------------------------------------------------------- [16:26:45] Rick Carlino(@RickCarlino):https://www.reddit.com/r/ruby/comments/3bi3qx/opal_playground_like_js_fiddle_but_dom/ Comments are flowing in on Reddit. ---------------------------------------------------------------------------------------------------- [16:29:41] Ángel M(@Angelmmiguel):Same onhttps://www.reddit.com/r/ruby/comments/3biidf/a_box_to_compile_and_run_ruby_code_on_your_website/ :) ---------------------------------------------------------------------------------------------------- [16:30:19] Ángel M(@Angelmmiguel):I'm developing multitab (multiple files) on voces ---------------------------------------------------------------------------------------------------- [16:30:31] Ángel M(@Angelmmiguel):boxes* ---------------------------------------------------------------------------------------------------- [16:31:07] Rick Carlino(@RickCarlino):Looks like you're loading Opal over insecure HTTP (no 's') and chrome won't let me load the page . ---------------------------------------------------------------------------------------------------- [16:36:26] Forrest Chang(@fkchang):@ylluminate that's a pretty good idea, except that I'd have to deal w/javascript. I'm planning on having stuff that is a fair amount different than what jsbin and clones do, so I'm probably going to pursue that direction, while I'm inspired ---------------------------------------------------------------------------------------------------- [16:36:56] Forrest Chang(@fkchang):@RickCarlino cool on the comments and ur presence on the reddit thread ---------------------------------------------------------------------------------------------------- [16:37:33] Forrest Chang(@fkchang):So should I push my current 'embedded in the iframe, but not too good looking or response opal-irb' that I have displayed in the screen shot? ---------------------------------------------------------------------------------------------------- [16:37:57] Forrest Chang(@fkchang):oh, and any style wizardry assistance would be appreciated ---------------------------------------------------------------------------------------------------- [17:49:03] Jikku Jose(@JikkuJose):Any idea why the `css class` isn't getting set in the initialize method?: http://tinyurl.com/opal-box-class ---------------------------------------------------------------------------------------------------- [17:50:05] Jikku Jose(@JikkuJose):If I uncomment the explicit setting of the class it works. ---------------------------------------------------------------------------------------------------- [19:16:47] Forrest Chang(@fkchang):how quick should I push to opal-playground, I like added 3 features, but I'd sort of like some vetting ---------------------------------------------------------------------------------------------------- [19:52:04] Rick Carlino(@RickCarlino):Maybe you could push a 'staging' that we can all QA off of and let you know. Is that what you're worried about? Bugs / compat issues? ---------------------------------------------------------------------------------------------------- [19:52:19] Mitch VanDuyn(@catmando):I was just using it with @JikkuJose problem, and it was very cool ---------------------------------------------------------------------------------------------------- [19:53:53] Mitch VanDuyn(@catmando):btw @JikkuJose I don't see anything wrong with that code... I suspect its because Element is just a thin wrapper on Jquery and hence does not work. But I'm not sure. Folks: Is there any known problem with circular requires? I have several classes that end up with a circular dependency. ---------------------------------------------------------------------------------------------------- [20:21:28] Forrest Chang(@fkchang):@RickCarlino something like that. I would like to make some sort of preview version available before I foist it upon the world ---------------------------------------------------------------------------------------------------- [20:24:43] Forrest Chang(@fkchang):On another note, I'm at an interesting place where working on opal-playground reinforces 2 'not particularly known/understood ideas' I want to pitch for opal, namely * being able to edit code in the app and not have to re setup state (ala smalltalk images and lisp machines) is a huge advance that most ppl can't appreciate (call it Editor/IDE Blub) * Lissio's way (doesn't have to be lissio, but no other framework does it) of combining markup, style and behavior into 1 coherent ruby class is both more productive, and responds to increasing complexity better. That being said, it's potentially a long rambling blog post I don't know I have time to write while it's fresh in my brain ---------------------------------------------------------------------------------------------------- [20:30:29] Mitch VanDuyn(@catmando):@fkchange - I am coming rapidly to the same conclusion working with opal-react (react.rb)... Current state of react.rb that my team is using is the same idea. behavior and markup are in together in small simple classes (have not really pushed my team to bring the style in, but I think that's next.) And like wise its pretty obvious you could have a great development environment where you developed these classes in a very interactive environment. I am imaging typing things like: edit Component::Navbar and having that fire up a window with the Navbar code. When you save it fires up a react rerender of the component... ---------------------------------------------------------------------------------------------------- [20:31:46] Mitch VanDuyn(@catmando):The whole thing could be somehow backed by github, so you have builtin config management too. ---------------------------------------------------------------------------------------------------- [20:33:22] Forrest Chang(@fkchang):@catmando react still does css in the normal (i.e. cascaded over all kinds of css files and not associated direct w/the component, nor in a dsl) way, no? My particular issue was w/css, looking for the right files, changing mental languages, etc. In lissio, I believe a lot of cascading types of practices would be unnecessary due to using css inheritance ---------------------------------------------------------------------------------------------------- [20:34:42] Mitch VanDuyn(@catmando):@fkchang - yes I hate that too, but there are folks in the react.js world who have tools that allow the css to be nicely placed right in the component. I want to look into that for opal-react. ---------------------------------------------------------------------------------------------------- [20:35:25] Forrest Chang(@fkchang):@catmando related, I had planned to make a lissio component editor, which is in 20/20 hindsight is functionally equivalent to opal-playground, but each editor is ruby and it maps down to 1 class, and had thought that I'd want to add opal-react to the playground, except that I haven't played w/it at all ---------------------------------------------------------------------------------------------------- [20:35:51] Forrest Chang(@fkchang):@catmando nice, got some links so I can see what they are doing? ---------------------------------------------------------------------------------------------------- [20:36:04] Mitch VanDuyn(@catmando):However main priority was to get the system up, and get the team productive and they are used to style sheets. Meanwhile we really needed a way to talk to the active-record objects from within react, so that is done now (at least enough to move on.) ---------------------------------------------------------------------------------------------------- [20:39:07] Mitch VanDuyn(@catmando):Why don't we set up a time, and I can get a staging version of what we have up and running and then do some code walk throughs and show you how it works. How does that sound? ---------------------------------------------------------------------------------------------------- [20:40:30] Mitch VanDuyn(@catmando):@fkchang - re: the editor. Exactly the idea. works good with react to, as each component = a class, so if you had a class editor then it = a component editor. ANd because react is well reactive, then it should be almost no work to make saving the changes == a render update! ---------------------------------------------------------------------------------------------------- [20:41:54] Mitch VanDuyn(@catmando):@fkchang - yes it would be nice to have some way to pull in various components depending on what people are doing. ---------------------------------------------------------------------------------------------------- [20:54:43] Forrest Chang(@fkchang):@catmando yeah, I'd love to see what you guys were doing, also the css in react component thing too ---------------------------------------------------------------------------------------------------- [20:56:34] Mitch VanDuyn(@catmando):@fkchang - well lets set a time! We can do it gitter tomorrow perhaps. To be clear... we are NOT doing the CSS thing in react (YET) but I am thinking we will just grab it right out lissio. It would work just the same I think. ---------------------------------------------------------------------------------------------------- [20:59:16] Forrest Chang(@fkchang):For a quickie thing, I could pull in opal-react lib and you could do everything thru the ruby window, does opal-react require everything, in lissio, you have to specifically require any components you want to subclass, so to do the lissio experiment, I'd have to do that ---------------------------------------------------------------------------------------------------- [20:59:40] Mitch VanDuyn(@catmando):@fkchang the only thing I might change about how lissio does it is to change this ```ruby css do rule '.title' do font size: 32.px end rule '.subtitle' do font size: 18.px, style: :italic end end ``` to just ```ruby rule '.title' do font size: 32.px end ``` as the css seems redundant. ---------------------------------------------------------------------------------------------------- [21:00:19] Forrest Chang(@fkchang):@catmando what time zone r u in? ---------------------------------------------------------------------------------------------------- [21:00:57] Forrest Chang(@fkchang):@catmando lissio does that, I believe, to 1) designate the css area 2), in that block is where the css dsl is active. @meh could answer definitively, but my explanation makes sense to me ---------------------------------------------------------------------------------------------------- [21:01:09] Mitch VanDuyn(@catmando):east coast. My only constraint though is my wife is returning from west coast tomorrow sometime so it would be best to do it before that. ---------------------------------------------------------------------------------------------------- [21:01:55] Forrest Chang(@fkchang):@catmando when does ur wife return? ---------------------------------------------------------------------------------------------------- [21:02:26] Mitch VanDuyn(@catmando):@re lissio... understood. In react.rb you `include React::Component` and then all the generator methods are available within that class. ---------------------------------------------------------------------------------------------------- [21:04:16] Mitch VanDuyn(@catmando):So thinking about a minimal experiment in opal-react: basically you need the gem loaded you need the component class defined then you need to attach the class to some dom element. ---------------------------------------------------------------------------------------------------- [21:06:25] Mitch VanDuyn(@catmando):There is a lot of magic being done to make the syntax very noise free, and I would have to think about what happens if you redefine the component. Should work....I will do a smoke test later and see what happens. ---------------------------------------------------------------------------------------------------- [21:15:18] Mitch VanDuyn(@catmando):@fkchang - not sure, but she is coming from Seattle so I am guessing pretty late... let me see if I can get txt her now. but I think we can assume anytime before 5:00 PM EDT ---------------------------------------------------------------------------------------------------- [21:33:44] Keith(@ktec):hi all, I wonder if someone could take a look at this for me when you have a minute. https://github.com/globalkeith/opal-pixi I'm trying to move the opal-pixi library forwards a get all the examples completed, however I've stumbled on some fairly simple stuff which I dont understand. Firstly when I try to implement an included Module, it seems to break all the inherited instance methods, and also when I upgrade to opal 7+ everything breaks and I dont really know where to start. If anyone can point me in the right direction with these and any other tips in general, I'm excited to take this project forward and complete all the examples on http://pixijs.github.io/examples/index.html many thanks ---------------------------------------------------------------------------------------------------- [21:37:38] Forrest Chang(@fkchang):@catmando that might be tough for me, I think I'm not available before 6pm ET ---------------------------------------------------------------------------------------------------- [21:38:11] Mitch VanDuyn(@catmando):i'll let you know when I know more... good chance i;ll be available late... ---------------------------------------------------------------------------------------------------- ############################## [2015-07-01] ############################## [00:20:34] Forrest Chang(@fkchang):ok, I've updated http://fkchang.github.io/opal-playground - added help, show compile error, show compiled js, embedded opal-irb, some other tweaks ---------------------------------------------------------------------------------------------------- [00:22:12] John Rizzo(@johnrizzo1):any good examples I can use to learn how to use components… the documentation only tells you the purpose and how they fit in but not how to create new ones... ---------------------------------------------------------------------------------------------------- [00:22:34] John Rizzo(@johnrizzo1):oops ---------------------------------------------------------------------------------------------------- [00:22:37] John Rizzo(@johnrizzo1)::) ---------------------------------------------------------------------------------------------------- [00:23:00] John Rizzo(@johnrizzo1):wrong chat ---------------------------------------------------------------------------------------------------- [00:51:48] Mitch VanDuyn(@catmando):@fkchang do u want to do a show and tell and 7:00 eastern tomorrow? ---------------------------------------------------------------------------------------------------- [00:58:44] Mitch VanDuyn(@catmando):And anybody else interested in react opal ---------------------------------------------------------------------------------------------------- [01:18:51] Forrest Chang(@fkchang):@catmando I think I can do that ---------------------------------------------------------------------------------------------------- [11:44:04] Andrzej Krzywda(@andrzejkrzywda):Hey all, as Arkency we launched React.js koans 2 days ago. To our surprise it gathered over 1500 GitHub stars and it's now a trending repo - https://github.com/arkency/reactjs_koans The original version uses ES6, but the main goal was to teach React.js not ES6 (not that much). Long story short - it would be great to put the Opal version as well. This may be a good promotion for Opal as React.js is nowe getting more and more popular. Someone already created an issue for that: https://github.com/arkency/reactjs_koans/issues/22 Just a full disclosure here - this repository has a book ad in the README - thanks to the people buying the book, we can spend more time/money on doing open source like this. If this is not a problem, then your help in doing the Opal version would be more than welcome. Even just porting the first exercise would be of much value - as then it would be easier for others to jump in and help with the next exercises. ---------------------------------------------------------------------------------------------------- [11:45:29] Elia Schito(@elia)::eyeglasses: watched ---------------------------------------------------------------------------------------------------- [13:11:27] Vais Salikhov(@vais):@andrzejkrzywda one of those 1500 stars is mine for what it's worth :) ---------------------------------------------------------------------------------------------------- [13:12:13] Andrzej Krzywda(@andrzejkrzywda):@vais thanks :) ---------------------------------------------------------------------------------------------------- [13:15:02] Vais Salikhov(@vais):@zetachang authored https://github.com/zetachang/react.rb which is an Opal wrapper around react.js ---------------------------------------------------------------------------------------------------- [13:15:02] Vais Salikhov(@vais):@zetachang authored https://github.com/zetachang/react.rb which is an Opal wrapper around react.js ---------------------------------------------------------------------------------------------------- [15:56:56] CJ Lazell(@cj):@elia morning.

Am I missing something? ---------------------------------------------------------------------------------------------------- [16:49:40] CJ Lazell(@cj):how is this code supposed to work? https://github.com/opal/opal/blob/master/lib/opal/sprockets/source_map_server.rb#L85 what is self? it’s never actually getting in there when path_info == wedge.map ---------------------------------------------------------------------------------------------------- [16:51:02] CJ Lazell(@cj):changing the regex to %r{^(.*)(\.self|\.map)$} makes it work ---------------------------------------------------------------------------------------------------- [16:51:23] CJ Lazell(@cj):gitter removed the backslashes ---------------------------------------------------------------------------------------------------- [17:05:27] CJ Lazell(@cj):created a ticket https://github.com/opal/opal/issues/968 ---------------------------------------------------------------------------------------------------- [20:46:49] Elia Schito(@elia):@cj `.self` comes from sprockets 3 and it's a "pipeline" intended to serve just the file you're requesting ---------------------------------------------------------------------------------------------------- [20:46:50] Elia Schito(@elia):https://github.com/rails/sprockets/blob/c46c6218573d3982879c6ef90074beb8077060e9/lib/sprockets.rb#L90-L92 ---------------------------------------------------------------------------------------------------- [20:47:50] Elia Schito(@elia):the main problem is that the whole thing is a huge hack on sprockets which won't support sourcemaps until v4 ---------------------------------------------------------------------------------------------------- [21:18:16] Mitch VanDuyn(@catmando):@fkchang Hey I don't think I can do this react-opal thing tonight, unless a bunch of people are going to e very dissappointed... I just have a bunch of stuff that I need to do. I think we can schedule it for next week.

---------------------------------------------------------------------------------------------------- [16:57:24] CJ Lazell(@cj):yee, trying to think of an easy re-create ---------------------------------------------------------------------------------------------------- [17:01:17] Elia Schito(@elia)::+1: ---------------------------------------------------------------------------------------------------- [17:03:28] CJ Lazell(@cj):@elia @vais https://github.com/opal/opal/issues/972 ---------------------------------------------------------------------------------------------------- [17:05:21] CJ Lazell(@cj):I’m a bug magent lol ---------------------------------------------------------------------------------------------------- [18:32:39] ylluminate(@ylluminate):we're still looking for some input on this: https://github.com/opal/opal/issues/965 ---------------------------------------------------------------------------------------------------- [18:33:04] ylluminate(@ylluminate):been about 6 days... :) ---------------------------------------------------------------------------------------------------- [18:46:55] Forrest Chang(@fkchang):@ylluminate :point_up: [June 26, 2015 9:09 AM](https://gitter.im/opal/opal?at=558d793198f9c0bc3da03e02) ---------------------------------------------------------------------------------------------------- [18:51:57] Gabriel Rios(@gabrielrios):@fkchang I got that, but what I’m wondering is why can’t opal take cara of that ---------------------------------------------------------------------------------------------------- [18:57:49] Gabriel Rios(@gabrielrios):And I sure that ‘toll free bridge’ classes might not be something common, someone coming from ruby would expect the `#initialize` method to work, instead of having to overriding `.new` ---------------------------------------------------------------------------------------------------- [19:04:02] ylluminate(@ylluminate):@fkchang thus why we're hoping that @adambeynon @elia @meh or someone can chime in with some clarification on that front... :fire: ---------------------------------------------------------------------------------------------------- [20:28:56] Forrest Chang(@fkchang):hmm, would documenting that suffice? ---------------------------------------------------------------------------------------------------- [20:29:36] Forrest Chang(@fkchang):because I can see in Ruby-fying a toll free bridged class, you might change what you pass in vs automatically assuming they match 1 to 1 ---------------------------------------------------------------------------------------------------- [20:32:09] Forrest Chang(@fkchang):so you wouldn't necessarily auto generate a new function ---------------------------------------------------------------------------------------------------- [20:36:15] Gabriel Rios(@gabrielrios):Yes, that was exactly my point on the issue. I’m trying to clarify this so we can at least add documentation for this, as wrapping JS libraries as so important for opal and deserves some docs ---------------------------------------------------------------------------------------------------- [21:11:18] ylluminate(@ylluminate):Right, it is critically important for Opal to have an exceptionally well documented and authoritative wrapping tutorial / document. ---------------------------------------------------------------------------------------------------- [23:46:44] Forrest Chang(@fkchang):It's my intent to document wrapping and other stuff in a series of blog posts, possibly that'll be the basis of the official docs? ---------------------------------------------------------------------------------------------------- [03:14:46] Jamie Gaskins(@jgaskins):@fkchang Re: "Lissio's way (doesn't have to be lissio, but no other framework does it) of combining markup, style and behavior into 1 coherent ruby class" — Clearwater does it pretty similarly to React: https://gist.github.com/jgaskins/746f65ccbf267dca36a6 Notice `{ style: style }` in some of the attribute hashes. ---------------------------------------------------------------------------------------------------- [03:17:08] Jamie Gaskins(@jgaskins):It's pretty awesome. It makes components completely self-contained, which makes it possible to extract your components to gems without having to add stylesheets for them. ---------------------------------------------------------------------------------------------------- [05:20:33] Jikku Jose(@JikkuJose):@catmando thanks for taking a look; I was going mad about why that wasn't working! Did you mean to say `super` method cannot be trusted to work as it should be? ---------------------------------------------------------------------------------------------------- [05:21:24] Jikku Jose(@JikkuJose):Other than that; I don't see any problem with this: http://tinyurl.com/opal-box-class ---------------------------------------------------------------------------------------------------- [05:23:29] Jikku Jose(@JikkuJose):@fkchang great work with Opal playground; perhaps a short url generating system can be built to share the links easily ---------------------------------------------------------------------------------------------------- [06:59:35] Forrest Chang(@fkchang):@jgaskins cool, I will have to get around to checking it out ---------------------------------------------------------------------------------------------------- [07:00:06] Forrest Chang(@fkchang):@JikkuJose thx, maybe a bit.ly or similar interface or something ---------------------------------------------------------------------------------------------------- [07:21:56] Jikku Jose(@JikkuJose):@fkchang yes! It will make copying a breeze ---------------------------------------------------------------------------------------------------- [07:27:59] Elia Schito(@elia):@fkchang @JikkuJose I suggest https://git.io ---------------------------------------------------------------------------------------------------- [14:30:45] CJ Lazell(@cj):@elia so is the reason it’s not getting passed because it’s not in a white list. similar to roda assets? can’t we just remove the self for now so that it works? ---------------------------------------------------------------------------------------------------- [14:32:42] Elia Schito(@elia):@cj self it's a sprockets thing so it's not a choice. The code you posted uses sprockets or it's something based on roda or custom? ---------------------------------------------------------------------------------------------------- [14:33:51] CJ Lazell(@cj):It’s using the code you gave me before. but it can’t get past this line https://github.com/opal/opal/blob/master/lib/opal/sprockets/source_map_server.rb#L85 ---------------------------------------------------------------------------------------------------- [14:34:19] CJ Lazell(@cj):the .map file exists, because if I remove \.self it will work ---------------------------------------------------------------------------------------------------- [14:35:33] CJ Lazell(@cj):https://github.com/wedgeio/wedge/blob/master/lib/wedge/middleware.rb#L21-L25 and is used on line 115 ---------------------------------------------------------------------------------------------------- [14:37:31] CJ Lazell(@cj):that line in the opal code would never pass as the regex is looking for some_file.self.map ---------------------------------------------------------------------------------------------------- [14:37:40] CJ Lazell(@cj):but the file is just some_file.map ---------------------------------------------------------------------------------------------------- [14:38:36] Elia Schito(@elia):What I don't get is why the files are there without the .self extension ---------------------------------------------------------------------------------------------------- [14:39:20] CJ Lazell(@cj):@elia so are they supposed to be some_file.self.map? ---------------------------------------------------------------------------------------------------- [14:40:01] CJ Lazell(@cj):because the file it’s looking for and adds to the js is some_file.map ---------------------------------------------------------------------------------------------------- [14:50:15] Elia Schito(@elia):@cj yes, they're supposed to have that `.self`, is your sprockets environment using debug mode? ---------------------------------------------------------------------------------------------------- [14:50:47] CJ Lazell(@cj):https://github.com/wedgeio/wedge/blob/master/lib/wedge/middleware.rb#L16 ---------------------------------------------------------------------------------------------------- [14:53:20] Elia Schito(@elia):@cj maybe you're calling assets without the `?body=1` param ---------------------------------------------------------------------------------------------------- [14:53:21] Elia Schito(@elia):https://github.com/rails/sprockets-rails/blob/master/lib/sprockets/rails/helper.rb#L60 ---------------------------------------------------------------------------------------------------- [14:53:56] CJ Lazell(@cj):@elia ye I’m not doing that, didn’t know you had too lol…. is that another hack? ---------------------------------------------------------------------------------------------------- [14:55:58] CJ Lazell(@cj):wow… adding that makes it work… random ---------------------------------------------------------------------------------------------------- [14:56:10] Elia Schito(@elia):no, it's how sprockets expect assets to be called for debugging, works out of the box in rails so I didn't thoght about it before ---------------------------------------------------------------------------------------------------- [14:56:21] Elia Schito(@elia):remove any sprockets cache you may have ---------------------------------------------------------------------------------------------------- [14:58:40] CJ Lazell(@cj):@elia thank you again. we should have docs for wedge soon. it’s pretty awesome :) ---------------------------------------------------------------------------------------------------- [14:58:57] Elia Schito(@elia)::+1: happy to help ---------------------------------------------------------------------------------------------------- [15:07:40] CJ Lazell(@cj):those links work btw ---------------------------------------------------------------------------------------------------- [15:07:42] CJ Lazell(@cj):@elia so another random issue when doing http://local.sh/assets/wedge/wedge.js?body=1 it doesn’t include opal, going to http://local.sh/assets/wedge/wedge.js does ---------------------------------------------------------------------------------------------------- [15:08:52] Elia Schito(@elia):yes because you're supposed to have a script[src] tag for each body=1 script ---------------------------------------------------------------------------------------------------- [15:09:19] Elia Schito(@elia):you can checkout the sprockets-rails helper.rb to see how it's done in rails ---------------------------------------------------------------------------------------------------- [15:10:00] Elia Schito(@elia):but more or less should be something like `sprockets_env['wedge.js'].to_a` ---------------------------------------------------------------------------------------------------- [15:10:15] Elia Schito(@elia):for each entry you need a script tag ---------------------------------------------------------------------------------------------------- [15:10:29] CJ Lazell(@cj):that seems terrible https://github.com/wedgeio/wedge/blob/master/lib/wedge.rb#L1-L21, I now see why that other person was suggesting being able to group them up ---------------------------------------------------------------------------------------------------- [15:11:20] Elia Schito(@elia):yep, I tried to merge maps together in 0.7 but they were broken and I wasnt' able to debug the problem ---------------------------------------------------------------------------------------------------- [15:11:49] Elia Schito(@elia):so in opal 0.8 we've gone back to separated assets ---------------------------------------------------------------------------------------------------- [15:13:51] CJ Lazell(@cj):http://www.giantfreakinrobot.com/wp-content/uploads/2011/08/vadernoo.jpg ---------------------------------------------------------------------------------------------------- [15:14:04] CJ Lazell(@cj):lol ---------------------------------------------------------------------------------------------------- [15:14:06] Elia Schito(@elia):lol ---------------------------------------------------------------------------------------------------- [15:15:28] Elia Schito(@elia):@cj try this impl ---------------------------------------------------------------------------------------------------- [15:15:29] Elia Schito(@elia):https://github.com/opal/opal/blob/2dce252fa67e5bd0afed83039d391fa5ab6edd12/lib/opal/sprockets/server.rb#L124-L142 ---------------------------------------------------------------------------------------------------- [15:15:49] CJ Lazell(@cj):I guess I’ll just add that in for now then, damn sprockets! that’s why I use roda assets :) ---------------------------------------------------------------------------------------------------- [15:16:39] CJ Lazell(@cj):ha… that’s what I was going to do… that’s fine for the main .js file. but the files you are requring via ajax I guess all need to be split up if they require other files right? ---------------------------------------------------------------------------------------------------- [15:17:39] Elia Schito(@elia):I guess so ---------------------------------------------------------------------------------------------------- [15:17:42] CJ Lazell(@cj):so basically if a rb file requires another file I have to make that a seperate file request, right? ---------------------------------------------------------------------------------------------------- [15:17:55] Elia Schito(@elia):yep ---------------------------------------------------------------------------------------------------- [15:18:07] CJ Lazell(@cj):I think I just threw up a little ---------------------------------------------------------------------------------------------------- [15:19:25] Elia Schito(@elia):if you find a good way to merge sourcemaps when concatenating assets I'll add it immediately (so to speak) ---------------------------------------------------------------------------------------------------- [15:20:00] Jared White(@jaredcwhite):@elia BTW, that latest require_self patch you did fixed all my sprockets problems. Sooo excited for the final 0.8 release!!! ---------------------------------------------------------------------------------------------------- [15:20:27] Elia Schito(@elia):@jaredcwhite the one in the PR? ---------------------------------------------------------------------------------------------------- [15:20:27] CJ Lazell(@cj):@jaredcwhite what sprocket problems were you having? ---------------------------------------------------------------------------------------------------- [15:20:32] Jared White(@jaredcwhite):I mean require_tree ---------------------------------------------------------------------------------------------------- [15:20:53] Elia Schito(@elia):yeah, I'll backport it to the 0-8-stable branch ---------------------------------------------------------------------------------------------------- [15:21:17] Elia Schito(@elia):maybe it's time to release after all cc @meh @adambeynon ---------------------------------------------------------------------------------------------------- [15:21:19] CJ Lazell(@cj):@elia one other thing, what is the need for https://github.com/opal/opal/blob/2dce252fa67e5bd0afed83039d391fa5ab6edd12/lib/opal/sprockets/processor.rb#L119 ? ---------------------------------------------------------------------------------------------------- [15:22:25] Jared White(@jaredcwhite):@cj I had a require_tree '.' In my application.js.rb file and that wasn't working. But it's now with Elia's PR ---------------------------------------------------------------------------------------------------- [15:22:26] Elia Schito(@elia):@cj good point, that's to bootstrap the main file since letting sprockets manage single files makes them all compile as "requireable" ---------------------------------------------------------------------------------------------------- [15:23:02] Elia Schito(@elia):so the main file needs to be required (as in `Opal.require('wedge')`) ---------------------------------------------------------------------------------------------------- [15:23:33] Elia Schito(@elia):the code you linked also takes care of stubbed and non opal files ---------------------------------------------------------------------------------------------------- [15:23:53] CJ Lazell(@cj):interesting… thank you ---------------------------------------------------------------------------------------------------- ############################## [2015-07-03] ############################## [02:45:16] Jikku Jose(@JikkuJose):In case someone is interested: I was able to solve the problem of not being able to assign class through `initialize` (http://tinyurl.com/opal-box-class) by creating a class method to call `initialize`: http://git.io/vqJBs ---------------------------------------------------------------------------------------------------- [02:48:50] Rick Carlino(@RickCarlino):@JikkuJose Neat find.

Now I am on mobile on a crappy wifi, so definitely have no answer for you at this time... ---------------------------------------------------------------------------------------------------- [10:08:10] Elia Schito(@elia):no worries at all ---------------------------------------------------------------------------------------------------- [10:19:42] Elia Schito(@elia):@/all 0.8.0.rc2 is out 🌝 please try it out! cc @ryanstout ---------------------------------------------------------------------------------------------------- [13:16:28] Vais Salikhov(@vais):@elia so will 0.8 include everything on master up to the point of release, or will it be capped at a certain commit? ---------------------------------------------------------------------------------------------------- [13:18:28] Elia Schito(@elia):@vais stops just before the merge of .JS stuff from jeremy evans ---------------------------------------------------------------------------------------------------- [13:18:50] Elia Schito(@elia):there was enough stuff already, had set a limit :D ---------------------------------------------------------------------------------------------------- [13:19:48] Elia Schito(@elia):the rest is set for 0.9 for which we can set our goals or just let some time pass by ---------------------------------------------------------------------------------------------------- [13:21:40] Vais Salikhov(@vais):@elia that's kind of a bummer cause there's been quite a fees bug fixes since then. ---------------------------------------------------------------------------------------------------- [13:22:32] Vais Salikhov(@vais):a few (typing on my phone, sorry) ---------------------------------------------------------------------------------------------------- [13:22:32] Elia Schito(@elia):Yeah, I know, my intention is to get out 0.9 way faster ---------------------------------------------------------------------------------------------------- [13:25:41] Vais Salikhov(@vais):Hmm I guess I'm trying to understand it from e.g. @ryanstout perspective maintaining a framework that depends on Opal. Volt is still on 0.6? If Volt updates to 0.8, how long will it be until Volt updates to 0.9? ---------------------------------------------------------------------------------------------------- [13:30:08] Vais Salikhov(@vais):I.e does it even make sense for them to update to 0.8 or just wait for 0.9? I'm definitely out of my depth here, just curious and wondering how people manage this kind of stuff. ---------------------------------------------------------------------------------------------------- [13:30:31] Elia Schito(@elia):@vais once 0.8 is out imo is time to start the works for 0.9 ---------------------------------------------------------------------------------------------------- [13:31:48] Elia Schito(@elia):also unless sprockets 4 is released in the meanwhile 0.9 will be mostly new feat & fixes ---------------------------------------------------------------------------------------------------- [13:32:31] Elia Schito(@elia):and 0.8 is so important for users bc it brings back working sourcmaps ---------------------------------------------------------------------------------------------------- [13:35:30] Vais Salikhov(@vais)::+1: ---------------------------------------------------------------------------------------------------- [13:36:36] Vais Salikhov(@vais):Re Sprockets 4.0 is that kinda like Perl 6 :trollface: ---------------------------------------------------------------------------------------------------- [13:55:51] Elia Schito(@elia):lol, I keep good hope tho, v3 is basically v4 with v2 backward compatibility, for opal 0.9 I might even be able to remove some hacks I had to do to make sourcemaps work for v2, but I need to update processors to the new format first ---------------------------------------------------------------------------------------------------- [14:02:16] Vais Salikhov(@vais):Yep, trolling aside, I really hope so as well. Thank you for all the work you've put in to make source maps work with the existing setup! Working source maps are absolutely critical to Opal' success if that even needs to be stated. ---------------------------------------------------------------------------------------------------- [14:04:41] Elia Schito(@elia):🌟 ---------------------------------------------------------------------------------------------------- [19:17:44] Ryan Stout(@ryanstout):@vais volt is currently on 0.7.2 ---------------------------------------------------------------------------------------------------- [19:18:10] Ryan Stout(@ryanstout):the upgrade to 0.8 wasn't too bad, so far the only thing that took some rethinking was the module system (since we were generating script tags ourself) ---------------------------------------------------------------------------------------------------- [19:18:29] Ryan Stout(@ryanstout):@elia and @vais thanks for fixing that issue, nice work ---------------------------------------------------------------------------------------------------- [02:33:29] Vais Salikhov(@vais):@elia something's broken in the latest rubyspec, I'm consistently getting this: ``` ..........FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - process out of memory rake aborted! ``` I am able to run your new `String#split` specs separately though, so the problem must be somewhere else, I will track it down after I fix `String#split` per the new specs. When it rains it pours. ---------------------------------------------------------------------------------------------------- [03:50:51] Vais Salikhov(@vais):@elia fixed the FATAL ERROR problem above and updated to latest rubyspec here https://github.com/opal/opal/pull/976. Next step once this and https://github.com/opal/opal/pull/974 are merged into master is to uncomment the failures for your new `String#split` specs in filters/bugs/string.rb, run the spec suite (everything should pass at that point), and commit. Makes sense? ---------------------------------------------------------------------------------------------------- [03:52:02] Vais Salikhov(@vais):@ryanstout we're getting there :) ---------------------------------------------------------------------------------------------------- [03:53:07] Ryan Stout(@ryanstout):@vais thanks, I owe you one :-) ---------------------------------------------------------------------------------------------------- [09:44:31] Elia Schito(@elia):@vais still around? ---------------------------------------------------------------------------------------------------- ############################## [2015-07-05] ############################## [02:02:56] ylluminate(@ylluminate):@vais @elia I tried to get some better timeline info for you out of the sprockets guys to not much avail: https://github.com/rails/sprockets/issues/68 ---------------------------------------------------------------------------------------------------- [06:43:24] Elia Schito(@elia):Yeah saw that ---------------------------------------------------------------------------------------------------- [16:22:40] Rick Carlino(@RickCarlino): ---------------------------------------------------------------------------------------------------- [16:23:50] Rick Carlino(@RickCarlino): ---------------------------------------------------------------------------------------------------- [16:24:14] Rick Carlino(@RickCarlino):I got it to work for primitives, but Object is not possible ---------------------------------------------------------------------------------------------------- [16:26:36] Rick Carlino(@RickCarlino):D'oh - found the answer in the docs.

Any tips? ---------------------------------------------------------------------------------------------------- [20:14:34] Forrest Chang(@fkchang):on that note, how stable is the AST format going to be? ---------------------------------------------------------------------------------------------------- [20:18:55] Forrest Chang(@fkchang):@adambeynon above was meant for you and not adambutler, but it's a bit premature, I think I can probably leverage node handlers for some of the stuff I want, so I might expose something else ---------------------------------------------------------------------------------------------------- ############################## [2015-07-06] ############################## [00:50:01] Penn Su(@pencilcheck):@AstonJ sorry just got to see your message.

any way around the dollar ---------------------------------------------------------------------------------------------------- [23:09:46] meh.(@meh):dancinglightning, how do you mean? ---------------------------------------------------------------------------------------------------- [23:11:34] Torsten Rüger(@dancinglightning):@meh doesn't read like ruby code, is all i meant. probably works well enough. can't think of an alternative either ---------------------------------------------------------------------------------------------------- [23:12:12] meh.(@meh):dancinglightning, what are you trying to do exactly? ---------------------------------------------------------------------------------------------------- [23:13:06] Torsten Rüger(@dancinglightning):@meh just get my pixi element into the dom at the right place. ---------------------------------------------------------------------------------------------------- [23:13:31] Elia Schito(@elia):the document should be a global, you can either use the dollar or a constant (e.g. Document) ---------------------------------------------------------------------------------------------------- [23:14:24] Torsten Rüger(@dancinglightning):ok, that was what i was looking for, thanks @elia , so i'm good ---------------------------------------------------------------------------------------------------- [23:14:55] George Plymale II(@ylluminarious):that is, anywhere in the defined scope of the program ---------------------------------------------------------------------------------------------------- [23:15:09] George Plymale II(@ylluminarious):@dancinglightning the dollar sign just indicates it's a global variable (accessible anywhere) ---------------------------------------------------------------------------------------------------- [23:16:46] George Plymale II(@ylluminarious):@dancinglightning also, i sometimes use `$$[:document]` to access the document. `$$` is the wrapped window object, so you can access properties like the document from there. ---------------------------------------------------------------------------------------------------- [23:17:17] George Plymale II(@ylluminarious):huh, weird, gitter just switched some of my messages around ---------------------------------------------------------------------------------------------------- [23:18:23] George Plymale II(@ylluminarious):re: `$$`, you don't have to use opal-browser to use `$$` ---------------------------------------------------------------------------------------------------- [23:19:05] George Plymale II(@ylluminarious):as you can see [here](http://opalrb.org/try/?code:%24%24.alert(%22test%22)), i'm not using opal-browser to access the window object ---------------------------------------------------------------------------------------------------- [23:19:37] George Plymale II(@ylluminarious):but opal-browser is nice when you need more fine-grained control ---------------------------------------------------------------------------------------------------- [23:21:51] George Plymale II(@ylluminarious):shoot, i think gitter broke my link because of the markdown ---------------------------------------------------------------------------------------------------- [23:48:12] Forrest Chang(@fkchang):@meh @elia thoughts on :point_up: [July 7, 2015 12:55 AM](https://gitter.im/opal/opal?at=559b85f01c1634674f8a5e45) ---------------------------------------------------------------------------------------------------- [23:50:26] meh.(@meh):fkchang, bridged classes imply having the methods directly added on the native class prototype ---------------------------------------------------------------------------------------------------- [23:50:30] meh.(@meh):that may be unwanted ---------------------------------------------------------------------------------------------------- [23:56:56] Forrest Chang(@fkchang):@meh right, but why would I chose bridging over just including Native, the implications are different on the JS side only ---------------------------------------------------------------------------------------------------- [23:58:37] meh.(@meh):that's the only reason, they're implementation dependant ---------------------------------------------------------------------------------------------------- [04:51:57] Rick Carlino(@RickCarlino):So when is usage of `to_n` warranted? ---------------------------------------------------------------------------------------------------- [04:52:35] Rick Carlino(@RickCarlino):Is it used mostly when interpolating code? ---------------------------------------------------------------------------------------------------- [07:55:28] Forrest Chang(@fkchang):@adambeynon @elia @meh when wrapping JS, why would one choose toll free bridging over include Native? In both cases you have to expose the methods via alias_native, though in toll free you have to define Klass.new and w/include Native, you can set @native in Klass#initialize ---------------------------------------------------------------------------------------------------- [08:03:22] Forrest Chang(@fkchang):The difference seems larger on the Javascript side, where they seem equivalent on the opal side ---------------------------------------------------------------------------------------------------- [14:13:58] AstonJ(@AstonJ):@pencilcheck www.metaruby.com - just let me know your username when you get there :) ---------------------------------------------------------------------------------------------------- [15:43:44] Forrest Chang(@fkchang):@jaredcwhite opalist deadline 8pm PT ish again tonight? Gonna be a tight squeeze for me ---------------------------------------------------------------------------------------------------- [16:07:22] Rick Carlino(@RickCarlino):Thanks for the reminder, @fkchang almost forgot! ---------------------------------------------------------------------------------------------------- [16:41:10] Torsten Rüger(@dancinglightning):Hi, i'm trying to build some graphical application using html canvas. ---------------------------------------------------------------------------------------------------- [16:41:30] Torsten Rüger(@dancinglightning):Does anyone know of ruby wrappers for other libraries than three and phaser ---------------------------------------------------------------------------------------------------- [16:42:25] Torsten Rüger(@dancinglightning):Maybe Famous ? Anything not have to code on the canvas. ---------------------------------------------------------------------------------------------------- [16:45:23] Forrest Chang(@fkchang):@dancinglightning I think there's a opal-raphael, though simply wrapping in Native works pretty well for raphael ---------------------------------------------------------------------------------------------------- [16:52:59] Torsten Rüger(@dancinglightning):@fkchang Thanks. I was looking for something not so tied to svg. more 2d context, possibly with 3d later. But simple is good. ---------------------------------------------------------------------------------------------------- [16:53:13] Torsten Rüger(@dancinglightning):Do you know the maintainer, it seems quite dead ---------------------------------------------------------------------------------------------------- [16:54:44] Forrest Chang(@fkchang):@dancinglightning I don't know the maintainer, it hit my radar a while's back, so I remembered that it's there. Looking back at the example on his readme, doesn't seem like he put much over what just wrapping w/Native gives you ---------------------------------------------------------------------------------------------------- [16:57:43] Forrest Chang(@fkchang):hmm, maybe I should take that repo over at some point ---------------------------------------------------------------------------------------------------- [16:58:23] Torsten Rüger(@dancinglightning):@fkchang it does seem very thin. 100 lines of code ---------------------------------------------------------------------------------------------------- [16:59:15] Forrest Chang(@fkchang):Yeah, his wrapper doesn't do much in the way or Ruby-fying, so it's nearly equivalent to wrapping in Native, but w/more work involved ---------------------------------------------------------------------------------------------------- [17:00:57] Torsten Rüger(@dancinglightning):@fkchang sorry, newbie: what is wrapping Native? some link i can read. ---------------------------------------------------------------------------------------------------- [17:01:56] Torsten Rüger(@dancinglightning):Just asking because if it's easy, i might consider doing pixi.js myself. seems the better library ---------------------------------------------------------------------------------------------------- [17:05:49] George Plymale II(@ylluminarious):@dancinglightning there's an opal-pixi you're welcome to contribute to: https://github.com/orbitalimpact/opal-pixi ---------------------------------------------------------------------------------------------------- [17:06:27] George Plymale II(@ylluminarious):it's in its very early stages right now, and we've been busy with opal-phaser lately ---------------------------------------------------------------------------------------------------- [17:06:47] Torsten Rüger(@dancinglightning):@ylluminarious i see you're everywhere. Thanks for the offer. i may just do that ---------------------------------------------------------------------------------------------------- [17:07:17] Torsten Rüger(@dancinglightning):Pixi seems just what i need, small enough and big enough. And well documented ---------------------------------------------------------------------------------------------------- [17:07:32] Torsten Rüger(@dancinglightning):Now i just need that link to the Native wrapping ---------------------------------------------------------------------------------------------------- [17:08:11] George Plymale II(@ylluminarious):@dancinglightning lol, thanks. you know what they say about great minds ;) ---------------------------------------------------------------------------------------------------- [17:12:14] Torsten Rüger(@dancinglightning):@ylluminarious I hope that we're talking v3?

DO the screencast ---------------------------------------------------------------------------------------------------- [17:39:39] Forrest Chang(@fkchang):targeting @jaredcwhite 's opalist newsletter, but I don't think I'll get it in time. I need to take 'speed screencasting' lessons from @RickCarlino ---------------------------------------------------------------------------------------------------- [17:40:45] Forrest Chang(@fkchang):The global thing is a quickie trick that I do in my normal apps -- make easily accessible certain variables to opal-irb (else they are hidden via closure). You could scope them in a class, but it's less typing to selectively use globals ---------------------------------------------------------------------------------------------------- [18:11:10] Rick Carlino(@RickCarlino):@fkchang I use a combo of `Kazaam` + `KDENlive!` on linux ---------------------------------------------------------------------------------------------------- [18:11:38] Rick Carlino(@RickCarlino):Record each as seperate screens and then use `shift + r` to trim silence off the ends of scene transitions ---------------------------------------------------------------------------------------------------- [18:12:00] Rick Carlino(@RickCarlino):Speaking of which, [EPISODE 8](http://datamelon.io/blog/2015/using-js-libraries-with-opal.html) came out today. I cover `Native` and `to_n` breifly ---------------------------------------------------------------------------------------------------- [20:04:18] Jamie Gaskins(@jgaskins):@JikkuJose Haven't used Handlebars, but there's `opal-haml` (https://github.com/opal/opal-haml) and `opal-slim`(https://github.com/jgaskins/opal-slim) for Haml and Slim. ---------------------------------------------------------------------------------------------------- [20:07:59] Jared White(@jaredcwhite):@fkchang Yep, tonight's the night. @RickCarlino is a screencasting MACHINE! ---------------------------------------------------------------------------------------------------- [20:08:25] Rick Carlino(@RickCarlino):I'm actually 14 different people. ---------------------------------------------------------------------------------------------------- [20:08:28] Jared White(@jaredcwhite):BTW, I'm running behind too - I was planning to writing up a front end design pattern article with some code examples, but I've just been super busy opening up a new office IRL and that's taken up lots of time. ---------------------------------------------------------------------------------------------------- [20:08:50] Jamie Gaskins(@jgaskins):@RickCarlino All inside a single trench coat, right? :-) ---------------------------------------------------------------------------------------------------- [20:08:55] Rick Carlino(@RickCarlino):(that was a joke, btw) ---------------------------------------------------------------------------------------------------- ############################## [2015-07-08] ############################## [00:04:48] Forrest Chang(@fkchang):@meh so what's an example where you want to the extend the native class prototype? ---------------------------------------------------------------------------------------------------- [00:05:56] meh.(@meh):it's when you do not want to that matters ---------------------------------------------------------------------------------------------------- [00:06:12] meh.(@meh):for example in IE6..8 extending the DOM would cause an exception ---------------------------------------------------------------------------------------------------- [00:08:41] Forrest Chang(@fkchang):@meh then it would seem that there's no advantage to toll free bridging. include Native seems to be across the board safer, unless you are wanting to call opal methods off of native js objects. Is there any performance benefits? ---------------------------------------------------------------------------------------------------- [00:09:23] meh.(@meh):from my tests there's no meaningful overhead between wrapping and extending ---------------------------------------------------------------------------------------------------- [00:11:51] Forrest Chang(@fkchang):@meh any history to the name "toll free" bridging? It would seem to imply that include Native is "toll required" bridging, to which I ask, "what is the toll?" ---------------------------------------------------------------------------------------------------- [00:12:21] Forrest Chang(@fkchang):though I think toll free bridging is done on numbers, strings, etc. for performance reasons ---------------------------------------------------------------------------------------------------- [00:12:28] Forrest Chang(@fkchang):rather than wrapping those ---------------------------------------------------------------------------------------------------- [00:13:29] meh.(@meh):those are not for performance reasons ---------------------------------------------------------------------------------------------------- [00:13:31] meh.(@meh):but for usability reasons ---------------------------------------------------------------------------------------------------- [00:13:40] meh.(@meh):you'd have to call #to_n on all of them otherwise ---------------------------------------------------------------------------------------------------- [00:13:47] meh.(@meh):which would make it a pain in the ass even within the corelib ---------------------------------------------------------------------------------------------------- [00:14:16] meh.(@meh):to stay on the safe side you should still call #to_n on those tho ---------------------------------------------------------------------------------------------------- [00:14:27] meh.(@meh):because they call valueOf() on self or other things ---------------------------------------------------------------------------------------------------- [00:14:29] Forrest Chang(@fkchang):@meh so then, there is some sort of benefit to toll free bridging, but what would it be? ---------------------------------------------------------------------------------------------------- [00:15:13] meh.(@meh):for things that aren't in the corelib? none ---------------------------------------------------------------------------------------------------- [00:16:10] Forrest Chang(@fkchang):that's a start. I'll note that opal-jquery does toll free bridging on element. @elia said he took advantage of the js object being extended, I'd be curious as to what circumstances ---------------------------------------------------------------------------------------------------- [00:16:24] Forrest Chang(@fkchang):@meh does opal-browser do any toll free bridging? ---------------------------------------------------------------------------------------------------- [00:16:45] meh.(@meh):nope ---------------------------------------------------------------------------------------------------- [00:17:24] Forrest Chang(@fkchang):so then general advice would be to favor include Native then ---------------------------------------------------------------------------------------------------- [00:17:37] meh.(@meh):yep ---------------------------------------------------------------------------------------------------- [00:18:01] Forrest Chang(@fkchang):thx ---------------------------------------------------------------------------------------------------- [00:18:15] Forrest Chang(@fkchang):@meh btw, working on anything cool lately? ---------------------------------------------------------------------------------------------------- [00:18:24] meh.(@meh):working on a game in Rust ---------------------------------------------------------------------------------------------------- [00:18:44] Forrest Chang(@fkchang):ironically, my 13 yr old son just wrote a tic tac toe game in Rust ---------------------------------------------------------------------------------------------------- [00:18:55] meh.(@meh):noice ---------------------------------------------------------------------------------------------------- [00:19:13] meh.(@meh):send him towards glium and 3d stuff :^) ---------------------------------------------------------------------------------------------------- [00:20:14] Forrest Chang(@fkchang):yeah, he impresses me, taught himself java to write an adventure game, then ruby for another text based game, started SICP, but when stalled redirected to Rust. I explained to him virtualbox and he's been running different distro's to do his develpoment on ---------------------------------------------------------------------------------------------------- [01:33:30] Torsten Rüger(@dancinglightning):@meh i was trying to follow the native discussion and looked at browser source. A lot of include Native there, but not much alias_native. I wonder is it even possible to use alias_naive when wrapping a larger api (for me pixi). I seems that "ruby" objects would make it back into the js framework and boom ---------------------------------------------------------------------------------------------------- [01:35:02] Torsten Rüger(@dancinglightning):Maybe just for simple attribute readers ? ---------------------------------------------------------------------------------------------------- [02:04:36] Jikku Jose(@JikkuJose):@jgaskins Thanks! I will look into it! Infact I prefer Haml better, I didn't expect to see it. ---------------------------------------------------------------------------------------------------- ############################## [2015-07-09] ############################## [08:23:42] Christian Käser(@dfyx):@fkchang yeah, Raphael works great with opal ---------------------------------------------------------------------------------------------------- [08:23:53] Christian Käser(@dfyx):I use it in my project to generate some pie charts ---------------------------------------------------------------------------------------------------- [16:39:56] Forrest Chang(@fkchang):@meh @elia @adambeynon I'm thinking perhaps the time to use toll free bridging is when you are passing back your objects to js. W/toll free bridging, you extend the js prototype, so the object you actually pass around is the js one. W/ include Native, you wrap the object and it's @native that is the actual js object, so passing the wrapper back to the original js isn't as seemless ---------------------------------------------------------------------------------------------------- [17:09:07] Forrest Chang(@fkchang):In my mucking w/Raphael and opal, I haven't needed to pass my object back to raphael, so it seems fine to just wrap it w/native, but I can imagine other js libs where you have objects, and you have to pass them back to the js libs a lot more in normal, where toll free bridging allows the actual js object get passed back vs. an opal wrapper obj that you have to expose the @native object back to js ---------------------------------------------------------------------------------------------------- [17:42:28] Forrest Chang(@fkchang):@all, wanted to pimp out the rspec part of opal-playground (which @adambeynon wrote). I've been using it w/a coworker to debate over how a spec should work ---------------------------------------------------------------------------------------------------- [17:43:00] Forrest Chang(@fkchang):http://git.io/vqMDa ---------------------------------------------------------------------------------------------------- [17:47:31] Forrest Chang(@fkchang):Pretty damn handy for real life dev ---------------------------------------------------------------------------------------------------- [19:09:35] Torsten Rüger(@dancinglightning):@fkchang i homed in on pixi, which i find the more complete package while still small-ish. ---------------------------------------------------------------------------------------------------- [19:09:36] Torsten Rüger(@dancinglightning):It just got a makeover with native, which i took to the extreme (just trying around) as you can see eg https://github.com/orbitalimpact/opal-pixi/blob/master/lib/opal/pixi/sprite.rb ---------------------------------------------------------------------------------------------------- [19:10:29] Torsten Rüger(@dancinglightning):It seems to unrap "ruby" objects and there is a possibility with the :as option to wrap the result. It's very smooth i think ---------------------------------------------------------------------------------------------------- [19:11:37] Torsten Rüger(@dancinglightning):The "on" method even knows how to handle a block (and i assume pass it as a js function). ---------------------------------------------------------------------------------------------------- [19:12:26] Torsten Rüger(@dancinglightning):The only js left is in the constructor and any code to make the library "smarter" ---------------------------------------------------------------------------------------------------- [21:29:06] Forrest Chang(@fkchang):@dancinglightning cool, I've been thinking that a reason to use toll free bridging is when you need to pass your objects back to the original js a lot. I haven't hit it in Raphael (not that I've worked that much), so I don't see it needed there, but I have 0 experience w/pixi to know if that makes sense. I think it makes sense in opal-jquery that Element is toll free bridged, coz you pass your elements to other jquery functions often. ---------------------------------------------------------------------------------------------------- [22:12:27] Gabriel Rios(@gabrielrios):@fkchang Yes, so I think that while using the library you won't have much need to pass the original JS back (if the library is completely wrapped), it would only make sense for interacting with JS libraries that don't have an Opal counterpart, so yes opal-jquery Element makes a lot of sense as there's tons of jquery plugins out there. ---------------------------------------------------------------------------------------------------- ############################## [2015-07-10] ############################## [19:57:56] Stephen Russett(@StephenOTT):Hey, any performance comparisons between Opal and gopherjs? ---------------------------------------------------------------------------------------------------- [19:58:05] Stephen Russett(@StephenOTT):or any pro/con list? ---------------------------------------------------------------------------------------------------- [21:17:22] Forrest Chang(@fkchang):@StephenOTT interesting question, I'd be surprised if anyone has looked at both. I've only worked w/Go a little -- a websockets proxy, where I needed the speed and concurrency. With Go being a simpler, non dynamic language, I imagine gopherjs ought to be faster performing, if that actually makes a difference in your app. That being said, Ruby is higher level and more flexible, so I imagine coding a complex app in Opal could go faster. That gopherjs supports a form of goroutine on top of js is cool, we should consider imitating that in Opal, since there's no Ruby example to draw from. I volunteer @meh to work that magic ---------------------------------------------------------------------------------------------------- [21:17:58] meh.(@meh):fkchang, not compatible with Opal's design ---------------------------------------------------------------------------------------------------- ############################## [2015-07-12] ############################## [21:46:42] Ángel M(@Angelmmiguel):Hi @elia ---------------------------------------------------------------------------------------------------- [21:47:11] Ángel M(@Angelmmiguel):Opal.compile method (javascript) ---------------------------------------------------------------------------------------------------- [21:48:07] Ángel M(@Angelmmiguel):I loaded current version from opalrb.org (cdn) and used in my website ---------------------------------------------------------------------------------------------------- [21:52:20] Elia Schito(@elia):Be sure to load opal-parser.js too ---------------------------------------------------------------------------------------------------- [21:58:21] Ángel M(@Angelmmiguel):yes, the two libraries was loaded ---------------------------------------------------------------------------------------------------- [21:59:46] Ángel M(@Angelmmiguel):When I change url to use 0.7.1 version, it works well :) ---------------------------------------------------------------------------------------------------- [11:25:10] Ángel M(@Angelmmiguel):Hello! ---------------------------------------------------------------------------------------------------- [11:26:42] Ángel M(@Angelmmiguel):Do you delete the compile method on javascript library? ---------------------------------------------------------------------------------------------------- [11:26:53] Ángel M(@Angelmmiguel):I get an error when I try to use it ---------------------------------------------------------------------------------------------------- [14:39:31] Ángel M(@Angelmmiguel):I downgrade the version of the library from current to 0.7.1 and it's ok :) ---------------------------------------------------------------------------------------------------- [21:45:49] Elia Schito(@elia):@Angelmmiguel which method exactly? ---------------------------------------------------------------------------------------------------- ############################## [2015-07-13] ############################## [07:48:36] Elia Schito(@elia):@Angelmmiguel can you post the urls for which it doesn't work? ---------------------------------------------------------------------------------------------------- [08:12:34] Ángel M(@Angelmmiguel):@elia http://cdn.opalrb.org/opal/current/opal.min.js and http://cdn.opalrb.org/opal/current/opal-parser.min.js ---------------------------------------------------------------------------------------------------- [08:15:39] Elia Schito(@elia):@Angelmmiguel Ok, the solution is to `require "opal-parser"` from a ruby/opal script ---------------------------------------------------------------------------------------------------- [08:15:55] Elia Schito(@elia):or `Opal.require('opal-parser')` in JS land ---------------------------------------------------------------------------------------------------- [08:16:45] Elia Schito(@elia):eg. ``` ``` ---------------------------------------------------------------------------------------------------- [08:18:06] Ángel M(@Angelmmiguel):Ah! ok @elia, thanks for the reply.

Does a week from today at 1:00 PM work? ---------------------------------------------------------------------------------------------------- [20:30:53] Mitch VanDuyn(@catmando):we can do it on gitter on the react.rb room, I'll set up some thing to share code etc. ---------------------------------------------------------------------------------------------------- [20:33:53] Forrest Chang(@fkchang):@catmando thurs is generally my busiest day ---------------------------------------------------------------------------------------------------- [20:34:47] Mitch VanDuyn(@catmando):@fkchang, np wednesday is also good for me, but really anytime works, and I can rearrange things. ---------------------------------------------------------------------------------------------------- [20:43:12] Forrest Chang(@fkchang):@catmando how's fridays, my schedule often clears up 1pm PT on fridays ---------------------------------------------------------------------------------------------------- [20:45:17] Mitch VanDuyn(@catmando):@fkchang, I am good at 1:00 PM PT next friday - actually would work very well for me. ---------------------------------------------------------------------------------------------------- [20:48:53] Forrest Chang(@fkchang):@catmando ok, let's shoot for that ---------------------------------------------------------------------------------------------------- [16:54:33] Ryan Stout(@ryanstout):congrats! ---------------------------------------------------------------------------------------------------- [17:28:34] ylluminate(@ylluminate):anything we can help out with to get .8 to volt? i know you'd mentioned you had been working on it @ryanstout ---------------------------------------------------------------------------------------------------- [17:29:11] Ryan Stout(@ryanstout):@ylluminate (fyi, this is the opal room). I'm really close, if things go well, I might have it out today. ---------------------------------------------------------------------------------------------------- [17:30:21] ylluminate(@ylluminate)::clap: ---------------------------------------------------------------------------------------------------- [17:56:44] Andrew Kalek(@anlek):Hello everyone, Just wondering if Opal is production ready? I haven't done much research into it yet but figured I could ask here. ---------------------------------------------------------------------------------------------------- [18:05:05] Mitch VanDuyn(@catmando):@anlek, I have a small team and we redoing our website front end in Opal, its going very well. We have had basically no problems. ---------------------------------------------------------------------------------------------------- [18:05:58] Andrew Kalek(@anlek):Interesting. I find that Opal website doesn't do a good job showing the rendered JS (like let's say CoffeeScript website) which makes me a bit uncomfortable. ---------------------------------------------------------------------------------------------------- [18:08:27] Mitch VanDuyn(@catmando):@anlek coffeescript was designed as more a syntax sugar on top of javascript, so that there is pretty much a 1:1 mapping between the two. Opal is true compiler that generates efficient javascript code, so while the code is readable if you really want to do that, you basically don't have to. ---------------------------------------------------------------------------------------------------- [18:09:04] Mitch VanDuyn(@catmando):@anlek but if you want to see what opal is doing try this: http://opalrb.org/try/ ---------------------------------------------------------------------------------------------------- [18:09:19] Andrew Kalek(@anlek):Wow, that's a good point that I didn't know about. ---------------------------------------------------------------------------------------------------- [18:09:47] Mitch VanDuyn(@catmando):What kind of project were you thinking of using opal for? ---------------------------------------------------------------------------------------------------- [18:10:23] Andrew Kalek(@anlek):No project in mind yet, I just read about Opal (and heard a podcast a few weeks back) and thought I'd look into it. ---------------------------------------------------------------------------------------------------- [18:10:33] Andrew Kalek(@anlek):Any idea how Opal works with things like Ember.js? ---------------------------------------------------------------------------------------------------- [18:11:20] Mitch VanDuyn(@catmando):@anlek - you could make it work I think easily enough. However... ---------------------------------------------------------------------------------------------------- [18:11:42] Andrew Kalek(@anlek):oh boy, here it comes... ;) ---------------------------------------------------------------------------------------------------- [18:12:07] Mitch VanDuyn(@catmando):we started using ember and got quite a few of our pages in ember, but it found the learning curve too steep. ---------------------------------------------------------------------------------------------------- [18:12:25] Andrew Kalek(@anlek):For Ember itself or using Ember with Opal? ---------------------------------------------------------------------------------------------------- [18:13:07] Mitch VanDuyn(@catmando):For ember itself... ---------------------------------------------------------------------------------------------------- [18:13:28] Gabriel Rios(@gabrielrios):@anlek would probably require a wrapper, there’s one for React.js (https://github.com/zetachang/react.rb), but there’s some Opal Frameworks too ---------------------------------------------------------------------------------------------------- [18:13:30] Andrew Kalek(@anlek):Oh, ok. I can deal with that. ---------------------------------------------------------------------------------------------------- [18:13:31] Mitch VanDuyn(@catmando):what we are doing in my shop is using Facebooks React + a set of gems that let you do everything in ruby. ---------------------------------------------------------------------------------------------------- [18:13:32] George Plymale II(@ylluminarious):@anlek there are a number of frameworks and libraries for opal, e.g., [voltrb](https://github.com/voltrb/volt), [vienna](https://github.com/opal/vienna) ---------------------------------------------------------------------------------------------------- [18:14:36] Mitch VanDuyn(@catmando):@anlek at this point with about 3 months experience I have become an absolute opal-react fanatic. ---------------------------------------------------------------------------------------------------- [18:16:53] Mitch VanDuyn(@catmando):But there is no technical reason why you can't put a wrapper on Ember. If you do want to chat about react + opal head over to the zetachang/react.rb gitter room for specific discussion there. ---------------------------------------------------------------------------------------------------- [18:17:23] Andrew Kalek(@anlek):@catmando Thanks, I'll look into it when the time comes ;) ---------------------------------------------------------------------------------------------------- [18:17:49] Andrew Kalek(@anlek):@ylluminarious Thanks, I have seen Vienna somewhere on the Opal site but didn't look into it. I'll check those out. ---------------------------------------------------------------------------------------------------- [18:17:55] Mitch VanDuyn(@catmando):@anlek - have fun! ---------------------------------------------------------------------------------------------------- [18:18:18] Andrew Kalek(@anlek):It's also nice to know there is a channel with so many nice people willing to help if I have any problems ;) ---------------------------------------------------------------------------------------------------- [18:20:07] George Plymale II(@ylluminarious):@anlek no problem ---------------------------------------------------------------------------------------------------- [18:33:53] Andrew Kalek(@anlek):Has anyone used Volt? ---------------------------------------------------------------------------------------------------- [18:34:52] George Plymale II(@ylluminarious):@anlek fyi, there's a volt room for discussion: https://gitter.im/voltrb/volt ---------------------------------------------------------------------------------------------------- [18:35:08] Andrew Kalek(@anlek):Wow, awesome, thanks! ---------------------------------------------------------------------------------------------------- [18:48:33] Forrest Chang(@fkchang):@anlek there are 2 other places to mess around with opal in the browser http://fkchang.github.io/opal-irb/index-embeddable.html#code:alert%20%22Hi%20anlek!%22 ---------------------------------------------------------------------------------------------------- [18:49:12] Forrest Chang(@fkchang):and http://git.io/vm2vM ---------------------------------------------------------------------------------------------------- [18:49:43] Andrew Kalek(@anlek):@fkchang first link doesn't seem to do anything for me (I see H1 and H2 content but can't click `show lrb`) ---------------------------------------------------------------------------------------------------- [18:49:52] Forrest Chang(@fkchang):u can see the compiled code in both, though more easily in the playground ---------------------------------------------------------------------------------------------------- [18:50:07] Andrew Kalek(@anlek):Second link looks great! ---------------------------------------------------------------------------------------------------- [18:50:30] Forrest Chang(@fkchang):For opal frameworks, I would also look at clearwater and lissio ---------------------------------------------------------------------------------------------------- [18:51:00] Forrest Chang(@fkchang):@anlek do you have an error in the javascript console for the 1st link? ---------------------------------------------------------------------------------------------------- [18:52:06] Andrew Kalek(@anlek):@fkchang https://www.evernote.com/l/ACR7qYRX5VtOzpvcWJkDvTwg4w1dUVjwESwB/image.png ---------------------------------------------------------------------------------------------------- [18:54:01] Forrest Chang(@fkchang):change your url to not have https in the header, are you using "always https" or similar plugin? ---------------------------------------------------------------------------------------------------- [18:54:19] Andrew Kalek(@anlek):Yeah, I think I do ---------------------------------------------------------------------------------------------------- [18:54:47] Forrest Chang(@fkchang):I'll fix it to not specifically http the dependency js at some point and it'll still work on https, but not certain when I'll get to it ---------------------------------------------------------------------------------------------------- [18:55:21] Forrest Chang(@fkchang):@anlek when it works it would come up like this ---------------------------------------------------------------------------------------------------- [18:55:45] Andrew Kalek(@anlek):@fkchang I turned of the https force, and now I can see it. very nice. ---------------------------------------------------------------------------------------------------- [18:56:13] Forrest Chang(@fkchang):[![Screenshot_7_16_15__11_55_AM.png](https://files.gitter.im/opal/opal/OiCj/thumb/Screenshot_7_16_15__11_55_AM.png)](https://files.gitter.im/opal/opal/OiCj/Screenshot_7_16_15__11_55_AM.png) ---------------------------------------------------------------------------------------------------- [18:56:24] Andrew Kalek(@anlek)::) ---------------------------------------------------------------------------------------------------- [18:56:47] Forrest Chang(@fkchang):@anlek sign up for the opalist.co newsletter too ---------------------------------------------------------------------------------------------------- [18:57:03] Forrest Chang(@fkchang):and more discussion at metaruby.com ---------------------------------------------------------------------------------------------------- [18:57:22] Andrew Kalek(@anlek):@fkchang Thanks, I'll look into it :) ---------------------------------------------------------------------------------------------------- [19:00:10] Mitch VanDuyn(@catmando):@fkchang - i've been meaning to ask you this: Why can't I type CRs into IRB? ---------------------------------------------------------------------------------------------------- [19:01:25] Mitch VanDuyn(@catmando):Like if I type ```ruby class Foo puts "I'm a class" end ``` I get ============ SyntaxError: An error occurred while compiling: (file) unexpected 'false' Source: (file):1:9 class Foo ---------------------------------------------------------------------------------------------------- [19:21:52] Forrest Chang(@fkchang):@catmando hit ctrl-M and use the multi line editor ---------------------------------------------------------------------------------------------------- [19:22:32] Forrest Chang(@fkchang):u should watch some of the online demos, it seems most ppl have no idea of 90% of the features there ---------------------------------------------------------------------------------------------------- [19:25:24] Forrest Chang(@fkchang):and if you want the link to anything in your history, navigate to it, and hit ctrl-L (l for link), and it gives you the link for that ---------------------------------------------------------------------------------------------------- [19:25:55] Forrest Chang(@fkchang):I do some things different than irb, but actually give more capability, and make it easier once u realize how it can work. Like irb, you can go up and down command history and edit anything, but multi line edit in irb sucks, so, you just hit ctrl-M (m for multiline) and get a syntax highlighted editor (that I'm adding code completion to). Edit, reformat to your hearts content, then evaluate ---------------------------------------------------------------------------------------------------- [19:28:31] Forrest Chang(@fkchang):I started to go down the road of if what you type on one line doesn't parse, to keep it open. I implemented some of that but it's not as robust as irb, but then I realized multi line editing in irb sucks, esp. if you made a mistake, it'd be easier and more productive to invoke an editor on your statement than to spend a lot of work making the "don't blow up if the statement goes past 1 line" way ---------------------------------------------------------------------------------------------------- [19:35:03] Mitch VanDuyn(@catmando):yeah that's much better... I agree, I would rather have the multi line edit option anyway. BTW anyway to steal this nice gitter interface with their multiline / single line capability? That would be so sweet. ---------------------------------------------------------------------------------------------------- [19:36:55] Mitch VanDuyn(@catmando):@fkchange... its very cool... I really want to get react.rb integrated so you can sit there and build a ui on the fly! ---------------------------------------------------------------------------------------------------- [19:38:14] Forrest Chang(@fkchang):@catmando that's an interesting idea, since I'm using jconsole for the terminal emulation, I suspect that would be more work that I'd hope, esp. the way gitter does inline change of the content. I imagine I need to make it more clear you can do multiline edit, aside from putting it in the help ---------------------------------------------------------------------------------------------------- [19:38:50] Forrest Chang(@fkchang):@catmando yeah, I need to carve out some time to checkout react.rb one of these days, it wouldn't be too hard to make a react.rb based editor ---------------------------------------------------------------------------------------------------- [19:39:05] Forrest Chang(@fkchang):I had planned to make one for lissio for a while now ---------------------------------------------------------------------------------------------------- [19:39:13] Mitch VanDuyn(@catmando):@fkchang... yeah I wouldn't want to work on it unless I could just steal it. (the gitter text editor) ---------------------------------------------------------------------------------------------------- [19:41:34] Mitch VanDuyn(@catmando):@fkchang - I am imagining you could have some kind of TDD playground where you built each component and a set of test scripts with it at the same time. ---------------------------------------------------------------------------------------------------- [19:50:14] Mitch VanDuyn(@catmando):General Question is it there any way to in opal with sprockets to conditionally compile stuff? If not how hard would it be to add? For example if you type `if PRODUCTION ...end` and PRODUCTION were false, the code would not even get generated? ---------------------------------------------------------------------------------------------------- [19:50:49] Forrest Chang(@fkchang):@catmando Compose mode just makes it multi line, codemirror gives me so much more capability (including the qualified autocomplete I working on) ---------------------------------------------------------------------------------------------------- [19:51:23] Mitch VanDuyn(@catmando):@fkchang is codemirror in there? or something you are working ---------------------------------------------------------------------------------------------------- [19:51:55] Forrest Chang(@fkchang):@catmando opal-inspector would do that and much more, but hindered w/o the ability to look up code by name, I've been thinking of some workarounds so I can get started and show some really neat things to get some momentum behind it ---------------------------------------------------------------------------------------------------- [19:52:23] Forrest Chang(@fkchang):@catmando I'm using codemirror as the editor ---------------------------------------------------------------------------------------------------- [19:53:36] Mitch VanDuyn(@catmando):gotcha... lookup code by name meaning getting the source code back? ---------------------------------------------------------------------------------------------------- [19:53:39] Forrest Chang(@fkchang):here's my pre qualified code complete (qualified meaning I tell you what it is) ---------------------------------------------------------------------------------------------------- [19:53:50] Forrest Chang(@fkchang):[![Screenshot_7_16_15__12_53_PM.png](https://files.gitter.im/opal/opal/Gm17/thumb/Screenshot_7_16_15__12_53_PM.png)](https://files.gitter.im/opal/opal/Gm17/Screenshot_7_16_15__12_53_PM.png) ---------------------------------------------------------------------------------------------------- [19:54:31] Mitch VanDuyn(@catmando):sweet ---------------------------------------------------------------------------------------------------- [19:55:00] Forrest Chang(@fkchang):@catmando yes, it's on @adambeynon 's list of todo's, but it's critical to simulation of smalltalk's object browser way of editing code that I demoed a prototype of a few years back ---------------------------------------------------------------------------------------------------- [19:56:52] Mitch VanDuyn(@catmando):@fkchang I assume its not a technical issue, just time right? Its just a matter of the parser keep track of stuff and storing it away right? I can see why its not done, just thinking what it will take to get it done :-) ---------------------------------------------------------------------------------------------------- [19:57:32] Forrest Chang(@fkchang):@catmando yeah, it' s a matter of storing it. Also to figure out some sort of api that could serve it up from both the server or in the client ---------------------------------------------------------------------------------------------------- [19:57:49] Forrest Chang(@fkchang):it's like 70% similar to what's done for source maps ---------------------------------------------------------------------------------------------------- [19:58:23] Mitch VanDuyn(@catmando):@fkchang, why not just store it in the javascript on the client (switchable for production mode of course) ---------------------------------------------------------------------------------------------------- [19:59:38] Mitch VanDuyn(@catmando):@fkchang can you do this in mrb today? ---------------------------------------------------------------------------------------------------- [19:59:39] Forrest Chang(@fkchang):@catmando that might be a first step, I have some grandiose plans about being able to start an app, develop it in the browser, and when the code is what I want, sending it back to the server, so there are some subtleties to work out. That being said, I have some lower hanging fruit ---------------------------------------------------------------------------------------------------- [20:00:48] Forrest Chang(@fkchang):@catmando irb doesn't do it but pry does it, and I planned on basically using the same interface they do, i.e. ```edit Class#method``` ---------------------------------------------------------------------------------------------------- [20:01:05] Forrest Chang(@fkchang):from opal-irb. I'd also make the class browser ala smalltalk ---------------------------------------------------------------------------------------------------- [20:01:21] Mitch VanDuyn(@catmando):@fkchang I am with you all the way on that. The only thing I would consider is what is the purpose of "sending it back to the server". I am thinking you want to send it to a git repo. ---------------------------------------------------------------------------------------------------- [20:01:59] Forrest Chang(@fkchang):sometimes the cmd line is where u want it, sometimes the gui, I'll do both ---------------------------------------------------------------------------------------------------- [20:02:54] Forrest Chang(@fkchang):@catmando sending it back to the server is a dev thing. Take this case, I develop in safari, get it working, then I send the stuff back to the server so I can test in FF or mobile ---------------------------------------------------------------------------------------------------- [20:03:25] Forrest Chang(@fkchang):I sort of envision some sort of PR's so I can figure which changes I want to actually commit to the repo. ---------------------------------------------------------------------------------------------------- [20:03:47] Forrest Chang(@fkchang):That said, the low hanging fruit is to just push it back to the server, and I can use git itself to decide whether or not to commit ---------------------------------------------------------------------------------------------------- [20:04:51] Forrest Chang(@fkchang):that might be the better way to do it, but I need to be able to pull up code by name and know where to put it back, etc. ---------------------------------------------------------------------------------------------------- [20:06:28] Mitch VanDuyn(@catmando):@fkchang well not very smalltalk'ish but if you basically were always editing a "file" then wouldn't it all work? ---------------------------------------------------------------------------------------------------- [20:07:52] Mitch VanDuyn(@catmando):@fkchang there is some advantage in the redundancy of having the file directory structure layed on top of the code structure (at least I find it so.) ---------------------------------------------------------------------------------------------------- [20:08:15] Forrest Chang(@fkchang):@catmando I was going to try something like that as one of my workaround steps\ ---------------------------------------------------------------------------------------------------- [20:08:39] Forrest Chang(@fkchang):there is no way of getting around file structure, because that's how it is stored ---------------------------------------------------------------------------------------------------- [20:08:46] Forrest Chang(@fkchang):on the server ---------------------------------------------------------------------------------------------------- [20:08:54] Forrest Chang(@fkchang):and I don't plan on making images like small talk ---------------------------------------------------------------------------------------------------- [20:09:36] Forrest Chang(@fkchang):opal-playground has been getting me to find smaller chunks of some of my ideas to implement, but I appreciate hearing your ideas. Small features can work me towards my loftier goals ---------------------------------------------------------------------------------------------------- [20:10:31] Mitch VanDuyn(@catmando):@fkchang, well actually I think with not too much work we could be using it in anger. ---------------------------------------------------------------------------------------------------- [20:10:52] Mitch VanDuyn(@catmando):@fkchang - on a different subject... ---------------------------------------------------------------------------------------------------- [20:11:00] Mitch VanDuyn(@catmando):if you have a few minutes... ---------------------------------------------------------------------------------------------------- [20:11:12] Forrest Chang(@fkchang):@catmando that'd be cool, having actual users outside of myself and my team could really help w/shaping it. Though I'd hope it's not in anger ---------------------------------------------------------------------------------------------------- [20:11:42] Mitch VanDuyn(@catmando):old guys expression perhaps (as opposed to playing) ---------------------------------------------------------------------------------------------------- [15:13:36] Elia Schito(@elia):@vais @meh @adambeynon might be a good time to release 0.8 wdyt? ---------------------------------------------------------------------------------------------------- [15:13:46] meh.(@meh):fine by me ---------------------------------------------------------------------------------------------------- [15:42:36] Vais Salikhov(@vais):I think it's time for 0.9 already :) so, yes. ---------------------------------------------------------------------------------------------------- [15:43:14] Elia Schito(@elia):2/3 is enough, releasing! ---------------------------------------------------------------------------------------------------- [15:44:15] Vais Salikhov(@vais)::tada: :sparkles: ---------------------------------------------------------------------------------------------------- [16:10:18] Gabriel Rios(@gabrielrios)::shipit: ---------------------------------------------------------------------------------------------------- [16:10:43] Elia Schito(@elia):https://twitter.com/rubygems/status/621713416126861313 ---------------------------------------------------------------------------------------------------- [16:12:13] Elia Schito(@elia):@/all finally v0.8 is out! 😄 Let's celebrate, update out apps and get ready for 0.9! ---------------------------------------------------------------------------------------------------- [16:13:38] George Plymale II(@ylluminarious)::D ---------------------------------------------------------------------------------------------------- [16:14:27] CJ Lazell(@cj):w00t! :D ---------------------------------------------------------------------------------------------------- [16:15:31] Torsten Rüger(@dancinglightning):well done ! ---------------------------------------------------------------------------------------------------- [16:49:01] ylluminate(@ylluminate):and almost to the 5,000th commit! ---------------------------------------------------------------------------------------------------- ############################## [2015-07-17] ############################## [23:02:21] Elia Schito(@elia):in dev only of course ---------------------------------------------------------------------------------------------------- [23:02:36] Elia Schito(@elia):https://twitter.com/rubygems/status/622177344002916352 ---------------------------------------------------------------------------------------------------- [23:06:12] Elia Schito(@elia):@ryanstout bedtime, keep me posted, would be definitely good to improve perf ---------------------------------------------------------------------------------------------------- [23:06:26] Ryan Stout(@ryanstout):@elia thanks for the help.

One of the best ever, both in content and presentation. It’s what got me to pick it up, thanks! ---------------------------------------------------------------------------------------------------- [18:50:08] Mitch VanDuyn(@catmando):@fkchang, am now... ---------------------------------------------------------------------------------------------------- [19:03:48] Forrest Chang(@fkchang):@dancinglightning thanks, I put a lot of work into that talk ---------------------------------------------------------------------------------------------------- [19:05:18] Torsten Rüger(@dancinglightning):@fkchang well it was great. btw wasn’t there some class browser ? ---------------------------------------------------------------------------------------------------- [19:07:37] Forrest Chang(@fkchang):Anyways, I was thinking about some form of web_require for opal. In opal-irb (and by proxy opal-playground) I implemented a require_js - demoed here where I require_js raphael.js to mess w/it http://git.io/vmGmQ. I was figuring if we had some sort of cdn where we compile all the opal libs, that could be useful for real time experimentation, I don't think I'd do that in a production app. Related, we could do a web_require on opal code itself if we setup the right type of repo, a rubygems for opal, per se, where we could resolve dependencies because we know where the code would live ---------------------------------------------------------------------------------------------------- [19:07:38] Forrest Chang(@fkchang):thoughts? ---------------------------------------------------------------------------------------------------- [19:09:17] Forrest Chang(@fkchang):@dancinglightning I demo'ed my "opal-inspector" prototype -- if you saw @catmando and my conversation here yesterday, I talked a bit about it. Long story short, I plan to borrow smalltalk and lisp machine stuff to make really cool opal tools, I'm kind of blocked on that feature I want @adambeynon but I'm looking to some workarounds to get something to show ---------------------------------------------------------------------------------------------------- [19:13:21] Mitch VanDuyn(@catmando):@fkchang so if you do a web_require 'my-opal-lib' it would just work? Neat idea. Could it be somehow integrated with sprockets so that in a production environment it grabs all the stuff while it builds the assets? ---------------------------------------------------------------------------------------------------- [19:14:16] Mitch VanDuyn(@catmando):The problem would be preventing unwanted config changes when new version of a gem were released. For that you are back to some kind of gemfile / gemfile.lock structure right? ---------------------------------------------------------------------------------------------------- [19:16:38] Forrest Chang(@fkchang):@catmando that's the idea. It's thought from the perspective of adding code at runtime. My initial thought is I'm in opal-irb (or playground, or the future opal-inspector) and I just want to pull something in that I didn't already have required on the server side (which is currently not possible -- you have gem install, require, etc... and restart app). So for experimenting or development that's useful, but I see that once I've figured out what I want to use, that I'd do it the normal way. That said, @ryanstout made some mention of wanting to be able to load something like opal-irb on demand, but not always, where something like this would be useful ---------------------------------------------------------------------------------------------------- [19:17:15] Mitch VanDuyn(@catmando):@fkchang, but perhaps it could all be implicit... so you web_require a file, it checks (server side) to see if that file has been required before. if not it gets it and adds it the assets. If its already there you have the one then you stay with that version, until you do some explicit action to remove. ---------------------------------------------------------------------------------------------------- [19:17:34] Forrest Chang(@fkchang):If we setup some sort of opalgems server, web_require could hit that, it'd know how to traverse the directories and compile to js in the browser. Dependencies on other opalgems could be resolved by convention ---------------------------------------------------------------------------------------------------- [19:18:03] Forrest Chang(@fkchang):etc. But an reasonable low fruit would be to have compiled versions of all the opal libs, and just use require_js (I think that should work) ---------------------------------------------------------------------------------------------------- [19:18:26] Forrest Chang(@fkchang):then I could require_js opal-react, for instance on opal-playground right now and mess w/it ---------------------------------------------------------------------------------------------------- [19:18:49] Forrest Chang(@fkchang):But if I'm the only one who wants this feature, I wouldn't spend much effort on it ---------------------------------------------------------------------------------------------------- [19:19:27] Forrest Chang(@fkchang):@catmando ur web_require is something to think of ---------------------------------------------------------------------------------------------------- [19:20:28] Forrest Chang(@fkchang):Maybe we don't need a repo, we could crawl source on github as long as we can figure out conventions ---------------------------------------------------------------------------------------------------- [19:20:38] Forrest Chang(@fkchang):for web_require that is ---------------------------------------------------------------------------------------------------- [19:21:26] Torsten Rüger(@dancinglightning):@fkchang maybe i misunderstand, but could this not be a opal.server feature, or a sinatra app that you write. ---------------------------------------------------------------------------------------------------- [19:23:08] Forrest Chang(@fkchang):@dancinglightning to serve as the "opalgems" server? ---------------------------------------------------------------------------------------------------- [19:25:08] Forrest Chang(@fkchang):I would've imagined that @adambeynon @elia and @adambeynon must've have thought about something like web_require/opalgems before ---------------------------------------------------------------------------------------------------- [19:25:29] Mitch VanDuyn(@catmando):however... all that said, how much does this really buy over simply releasing a gem? ---------------------------------------------------------------------------------------------------- [19:26:26] Forrest Chang(@fkchang):maybe there's some insights ---------------------------------------------------------------------------------------------------- [19:26:44] Forrest Chang(@fkchang):@catmando the whole point is to be able require things at run time ---------------------------------------------------------------------------------------------------- [19:27:03] Forrest Chang(@fkchang):the analogy is real irb, where anything I've installed, I can simply require it and then use it ---------------------------------------------------------------------------------------------------- [19:27:23] Forrest Chang(@fkchang):Now if you haven't installed, you still have gem install it, but everything is available at run time ---------------------------------------------------------------------------------------------------- [19:27:49] Forrest Chang(@fkchang):Gems are fine when you already know you want it, then u install, require it in your app etc. ---------------------------------------------------------------------------------------------------- [19:28:28] Mitch VanDuyn(@catmando):I see, well in that case, I think you can still use all the existing gem infrastructure. ---------------------------------------------------------------------------------------------------- [19:29:20] Forrest Chang(@fkchang):Again, if no one finds it useful, not something I'll spend a lot of time, but low hanging fruit is if opal-react or opal-pixi is compiled to js somewhere, I can just require_js them right now in anything that has opal-irb included and mess w/it, and I could do that right now -- that meets the need of "adding functionality at run time" ---------------------------------------------------------------------------------------------------- [19:31:56] Torsten Rüger(@dancinglightning):@fkchang I went through playing with 4 different opal libraries in 2 days. Never saw it as a problem to stop my server, change the gemfile, bundle and restart. It was the reading up and getting to know the libraries that took more time. ---------------------------------------------------------------------------------------------------- [19:31:59] Mitch VanDuyn(@catmando):Hmmm... I sort of see what you mean. Certainly some way to add more to opal-irb at run time is good, but not really sure ---------------------------------------------------------------------------------------------------- [19:32:31] Torsten Rüger(@dancinglightning):I do think that an irb on a running app (in dev mode) would be useful though ---------------------------------------------------------------------------------------------------- [19:33:04] Torsten Rüger(@dancinglightning):or a class / object inspector. a debugger as it were ---------------------------------------------------------------------------------------------------- [19:33:28] Mitch VanDuyn(@catmando):I'm with @dancinglightning. And beyond understanding the library, lets say you did automagically pull in opal-react, well that's nice but to make it useful there are going to have to be other stuff added. ---------------------------------------------------------------------------------------------------- [19:34:52] Gabriel Rios(@gabrielrios):@fkchang This might be useful, mostly for opal-irb indeed (and maybe opal-repl). But what I find really interesting about `require_js` is that we might want to use it on wrappers, right now everytime someone is going to use opal-pixi, opal-react and other libraries there’s the need to add the script tag, which someone might not be expecting ---------------------------------------------------------------------------------------------------- [19:35:01] Torsten Rüger(@dancinglightning):@fkchang didn’t mean to take the wind out there. I do think it’s good that you are thinking of how to improve development. It’s been the same for too many decades ---------------------------------------------------------------------------------------------------- [19:35:20] Mitch VanDuyn(@catmando):I think its a good feature, but I think there are bigger fish to fry that will get generate opal excitement. ---------------------------------------------------------------------------------------------------- [19:35:23] Forrest Chang(@fkchang):@dancinglightning running opal-irb on apps is really handy. I've used the "live gist" to even help a coworker debug by setting up the situation that went wrong ---------------------------------------------------------------------------------------------------- [19:35:28] Gabriel Rios(@gabrielrios):Anyway there was a opal-cdn thing, that looks down right now (https://github.com/opal/opal-cdn), and I remember @ylluminate talking about having a central cdn for all opal gems ---------------------------------------------------------------------------------------------------- [19:35:48] Forrest Chang(@fkchang):W/o opal-irb, it'd be so hard to get the situation over to him ---------------------------------------------------------------------------------------------------- [19:38:45] Mitch VanDuyn(@catmando):I am just thinking if we want to do this then just make it work with standard gem structure. Have opal-irb redefine require, so that it "knows" how to go the gem server find the gem extract the needed opal code, and pull it down. It might be easier to set up a rails / sinatra server that does the donkey work and caches the results. ---------------------------------------------------------------------------------------------------- [19:39:29] Forrest Chang(@fkchang):@dancinglightning no worries, a bunch of the stuff I have in mind, most people won't be able to appreciate until they use it. Some folks in the Ruby world are familiar w/the smalltalk dev env (see avdi's recent gushing on smalltalk for someone who has recently discovered it - or rediscovered it). I believe I am the only person I know in the Ruby community who has ever used a lisp machine, so there's somethings I'll borrow, that pretty much no one in the ruby community has seen. ---------------------------------------------------------------------------------------------------- [19:42:12] Forrest Chang(@fkchang):@gabrielrios my quickie require_js implementation was to insert a ` in the html, but what is source in this case? (Note this is straight opal code, no lissio, but I assume that was just an example) Right now the page looks like this: ```html Hello React >----- does this go here???? ----<
``` ---------------------------------------------------------------------------------------------------- [15:27:49] meh.(@meh):catmando, yes, that should work ---------------------------------------------------------------------------------------------------- [15:37:15] Mitch VanDuyn(@catmando):@meh gee sorry but source is of course not defined... in this context what is "source" going to be??? ---------------------------------------------------------------------------------------------------- [15:42:15] meh.(@meh):catmando, right ---------------------------------------------------------------------------------------------------- [15:42:19] meh.(@meh):catmando, let me check ---------------------------------------------------------------------------------------------------- [15:42:29] Mitch VanDuyn(@catmando):I'm getting it I think ---------------------------------------------------------------------------------------------------- [15:42:53] Mitch VanDuyn(@catmando):looked at load_asset_code, source is the source file name right? and then I need to grab the opal processor ---------------------------------------------------------------------------------------------------- [15:43:28] Mitch VanDuyn(@catmando):@meh GOT IT! Thanks... ---------------------------------------------------------------------------------------------------- [15:43:34] meh.(@meh):catmando, yeah, source is the file name ---------------------------------------------------------------------------------------------------- [15:43:53] meh.(@meh):catmando, so it knows what the main file to load from the module list is ---------------------------------------------------------------------------------------------------- [15:44:13] Mitch VanDuyn(@catmando):Should this be documented anywhere? I will update the docs, but I am a little unsure where it should go. ---------------------------------------------------------------------------------------------------- [15:44:30] meh.(@meh):catmando, no idea, I had elia work on that stuff because I didn't follow the changes through ---------------------------------------------------------------------------------------------------- [15:44:42] meh.(@meh):as in, to make lissio compatible with 0.8 ---------------------------------------------------------------------------------------------------- [15:46:28] Mitch VanDuyn(@catmando):Yeah well that is what happened here too... @elia I would like to update the docs to explain that if you are rolling your own loading function then you need to include a call to Opal::Processor.load_asset_code... its just not clear in the docs where this should go? ---------------------------------------------------------------------------------------------------- [16:42:53] Elia Schito(@elia):good question! I have no idea either, I think I mentioned it in the changelog tho ---------------------------------------------------------------------------------------------------- [17:21:59] Mitch VanDuyn(@catmando):@elia I think perhaps very briefly upfront under install / getting started with a link to a section towards the end with the details. How does that sound? ---------------------------------------------------------------------------------------------------- [17:23:17] Elia Schito(@elia):good, can you draft something for that, super busy for some hours ---------------------------------------------------------------------------------------------------- [18:26:42] Ryan Stout(@ryanstout):@elia you around? ---------------------------------------------------------------------------------------------------- [20:49:26] Mitch VanDuyn(@catmando):arghhh... why is including every, and after so darn hard. Every time I try to use those methods I beat my head on the wall for hours... right now I am including opal-browser in the gem file, but when I require opal-browser it breaks the Opal::Processor.load_asset_code! ---------------------------------------------------------------------------------------------------- [20:50:37] Mitch VanDuyn(@catmando):THERE!!! the gem file is called opal-browser, but you require browser. Maybe if I said that to myself 37 more times I will remember! ---------------------------------------------------------------------------------------------------- ############################## [2015-07-21] ############################## [19:09:31] Brayden Banks(@bb010g):(There's GNU Smalltalk, but it seems really meh to me.) ---------------------------------------------------------------------------------------------------- [19:25:27] Forrest Chang(@fkchang):@bb010g it's where it is in that video, waiting for the code/comments lookup feature that I was hoping @vais would be able to implement in @adambeynon 's place given all the commits he's been making . I've been getting some low hanging fruit ideas working on opal-playground and from @catmando so I'll probably revive them. I'm adding auto completion w/context to the editor in opal-irb, that I'll bring to opal-playground, then after a "say detour", I'll probably get back to doing something opal-inspector -y. I also can implement a couple of things that avdi gushed about in small talk on his blog lately, I might detour and do that so I can say, "but that already exists in opal..." ---------------------------------------------------------------------------------------------------- [19:27:43] Forrest Chang(@fkchang):on a related note, the opal inspector demo site will need to be server based, I think, any ideas now that heroku doesn't do free 24/7 dynos anymore? ---------------------------------------------------------------------------------------------------- [19:28:43] Brayden Banks(@bb010g):App Engine? ---------------------------------------------------------------------------------------------------- [21:43:13] Mitch VanDuyn(@catmando):@fkchang You can host it on one of our servers if you like, or easier yet we can sponsor the demo site on our heroku account. ---------------------------------------------------------------------------------------------------- [22:33:24] Forrest Chang(@fkchang):@catmando thanks, I might take u up on it when it actually happens ---------------------------------------------------------------------------------------------------- [22:35:31] Mitch VanDuyn(@catmando):No drama, just let me know and I'll set you up with a box ---------------------------------------------------------------------------------------------------- [00:11:56] Vais Salikhov(@vais):https://news.ycombinator.com/item?id=9918343 ---------------------------------------------------------------------------------------------------- [01:41:19] Vais Salikhov(@vais):@/all https://news.ycombinator.com/item?id=9918343 is at number 16 on the HN front page. This one could really use your comments/upvotes - it's a great opportunity to get some visibility for Opal and its ecosystem. Thanks! ---------------------------------------------------------------------------------------------------- [01:56:55] Rick Carlino(@RickCarlino):@vais What's amazing is the lack of "Snarky" comments that a lot of new libraries get. Seems like people are really excited. ---------------------------------------------------------------------------------------------------- [11:20:15] Vais Salikhov(@vais):@RickCarlino indeed! It stayed up on the front page for a while, and it was pretty quiet - not a single negative comment until almost the end. Very interesting reaction :smile: Also, if you want something to make it to the front page of HN these days, remember to include the word "react" in the title :wink: ---------------------------------------------------------------------------------------------------- [14:22:56] Mitch VanDuyn(@catmando):@rickcarlino r u referring to " ruby has an incredible amount of cruft, gotchas, and a massive stdlib".

The point is more about having a curated repository with links to everything available in the opal world. Perhaps "everything-opal" would be a more suitable name? ---------------------------------------------------------------------------------------------------- [06:35:46] Keith Salisbury(@globalkeith):btw, did anyone here go to Brighton Ruby? ---------------------------------------------------------------------------------------------------- [07:07:56] Forrest Chang(@fkchang):I did some playing around w/crystal, pretty impressed that the cases I was playing around were faster than golang, w/smaller binaries (I'll blog about it shortly to include benchmarks). I think a crystal backend makes for a good pairing w/opal, ruby end to end, and rocket fast w/good memory utilization ---------------------------------------------------------------------------------------------------- [16:26:46] Bozhidar Batsov(@bbatsov):the way things are going in 5 years nobody will be using MRI :-) ---------------------------------------------------------------------------------------------------- [16:28:23] Forrest Chang(@fkchang):@bbatsov there's some truth to that, looking at the ideas I have for rubyconf proposals, that is an implication, though until the other ruby derivatives have comparable amounts of gems, I think MRI still has longevity ---------------------------------------------------------------------------------------------------- [16:33:10] Bozhidar Batsov(@bbatsov):sure, that’s why I said 5 years :-) ---------------------------------------------------------------------------------------------------- [16:33:29] Bozhidar Batsov(@bbatsov):it’s interesting why there’s so little interested in Opal so far ---------------------------------------------------------------------------------------------------- [16:33:37] Bozhidar Batsov(@bbatsov):only around 80k downloads ---------------------------------------------------------------------------------------------------- [16:33:45] Bozhidar Batsov(@bbatsov):and 2.7k stars ---------------------------------------------------------------------------------------------------- [16:33:58] Bozhidar Batsov(@bbatsov):in Clojure-world, ClojureScript seems to be as popular as Clojure ---------------------------------------------------------------------------------------------------- [16:34:11] Bozhidar Batsov(@bbatsov):and probably will become more popular than Clojure pretty soon ---------------------------------------------------------------------------------------------------- [16:34:44] Bozhidar Batsov(@bbatsov):one would imagine people would be pretty happy to drop CoffeeScript for Ruby ---------------------------------------------------------------------------------------------------- [16:38:06] George Plymale II(@ylluminarious):@bbatsov i think that some people are actually attached to javascript and prefer CS over plain ruby because of its similarity to js. it's very strange, but it just seems like some people like javascript (which really just seems like masochism to me :P) ---------------------------------------------------------------------------------------------------- [16:48:08] Torsten Rüger(@dancinglightning):@bbatsov another reason why opal is not adopted may also be that the ruby community is rails heavy, and rails is server. The drive to client side app left the community and started ember. Not surprisingly because dhh is on record for a document based approach. And for small things coffee really is quite fine, you know where you’re at (no runtime, very stable..) ---------------------------------------------------------------------------------------------------- [16:50:28] George Plymale II(@ylluminarious):@dancinglightning i concur ---------------------------------------------------------------------------------------------------- [16:57:21] Torsten Rüger(@dancinglightning):and opal is great, a bit like ruby before rails. It needs it’s killer app, and on the app framework side there has been more dabbling, only now with volt is there is serious contendent. ---------------------------------------------------------------------------------------------------- [17:15:08] Bozhidar Batsov(@bbatsov):yep, guess that’s right ---------------------------------------------------------------------------------------------------- [17:15:16] Bozhidar Batsov(@bbatsov):Volt lead me to Opal ---------------------------------------------------------------------------------------------------- [18:04:45] Forrest Chang(@fkchang):@bbatsov as someone who's been evangelizing for a few years, I'm pretty surprised at the lack of uptake from the Ruby community. I suppose it's because people either think it's a toy (not mature enough, or not enough documentation/examples) and/or they are happy w/whatever JS based investment they already have. I read DHH's response to @AstonJ 's queries as "happy w/coffescript, and not on list of things to learn at this point". Opal has to be much more compelling to get people in that camp to switch, IMO. I think the route to popularity is to make it such a no brainer for Rails, that all those people w/substantial investment in Rails will start to adopt ---------------------------------------------------------------------------------------------------- [20:21:46] Elia Schito(@elia):@fkchang :+1: also agree with @dancinglightning, I see many many people that are rails programmers and wouldn't touch frontend with a ten-foot pole, no matter the language, to the point that I had a colleague (very skilled rubyist) that preferred to use backticks and plain JS ---------------------------------------------------------------------------------------------------- [20:26:09] Ryan Stout(@ryanstout):anyone know why doing: Time.now.usec displays: "Microseconds are not supported" I can't find where that is in the opal code. ---------------------------------------------------------------------------------------------------- [20:26:46] Elia Schito(@elia):stdlib/time i think ---------------------------------------------------------------------------------------------------- [20:29:02] Ryan Stout(@ryanstout):@elia I'm really confused on this one: http://opalrb.org/try/?code:puts%20Time.now.usec ---------------------------------------------------------------------------------------------------- [20:29:10] Ryan Stout(@ryanstout):https://github.com/opal/opal/blob/master/opal/corelib/time.rb#L377 ---------------------------------------------------------------------------------------------------- [20:31:05] Ryan Stout(@ryanstout):ok, nevermind, found where it was: https://github.com/opal/opal/commit/d4a3f94fc13cb979e80e6440ef099563df242815 ---------------------------------------------------------------------------------------------------- [20:31:18] Elia Schito(@elia):yeah: https://github.com/opal/opal/blob/0-8-stable/opal/corelib/time.rb#L258-L261 ---------------------------------------------------------------------------------------------------- [20:32:49] Ryan Stout(@ryanstout):thanks! ---------------------------------------------------------------------------------------------------- ############################## [2015-07-28] ############################## [03:56:24] Bozhidar Batsov(@bbatsov):@fkchang Opal certainly needs more promotion. These days every second Ruby conf I visit has a talk on Crystal, but I’ve yet to see anyone besides you and @ryanstout talk about Opal. I aslo found a talk by @elia, but it was in Italian. :-) ---------------------------------------------------------------------------------------------------- [04:23:32] Jared White(@jaredcwhite):Part of the problem may be brain-drain at this point -- many people that are keenly interested in heavy frontend dev have long jumped on the JS bandwagon, and people that are still really super into Ruby (and likely Rails) tend to be more backend focused. It's challenging to find folks in the client-side frame of mind that are gung-ho about coding in Ruby rather than something else. ---------------------------------------------------------------------------------------------------- [04:34:24] Ryan Stout(@ryanstout):@bbatsov I think its that the tools aren't there yet. Since most of the front-end tools are (currently) written in JS, they don't see the advantage of using opal. I think once we get more idiomatic ruby tools for the client side, people will see the benefit. That said, Volt seems to be getting lots of adoption. I think once its more feature complete it will ramp up pretty quickly. ---------------------------------------------------------------------------------------------------- [05:30:33] Forrest Chang(@fkchang):@bbatsov I keep submitting proposals for opal, but only one has been accepted. I keep trying though ---------------------------------------------------------------------------------------------------- [05:32:24] Forrest Chang(@fkchang):@jaredcwhite I think if we can show that browser based ruby is just ruby, more rubyist will adopt. I proposed a few talks where I basically tried to paint how when I code Ruby in the browser it's so much better than when I do JS, one thing I do instinctively is quickly abstract away browser specific code, so that 95% of the coding I do is "just Ruby" ---------------------------------------------------------------------------------------------------- [05:33:53] Forrest Chang(@fkchang):I suspect I need to find a better way to say it, or maybe I should just rewrite and submit again, maybe before wasn't the right time. I've also submitted a talk on how "all ruby web components was a good thing". In the post React days, this talk topic might make more sense. ---------------------------------------------------------------------------------------------------- [05:34:40] Forrest Chang(@fkchang):@ryanstout I should look into helping w/some volt tools ---------------------------------------------------------------------------------------------------- [05:35:29] Ryan Stout(@ryanstout):@fkchang hit me up if you have time, I would love to integrate some of your stuff into volt ---------------------------------------------------------------------------------------------------- [05:35:57] Ryan Stout(@ryanstout):also, yea, I keep getting talks rejected also.

The challenge is that it's a little like comparing apples and oranges. If you have any ideas on how to do that, lmk. You could compare Opal to MRI Ruby, but that's not very useful. I *do* use benchmarks to compare Opal to Opal when making changes to the corelib to make sure there are no performance regressions. And for that I *do* use MRI numbers as a baseline (but mostly for giggles). Here is an example: I am working on a large change to `Hash` to make it completely match Ruby semantics and pass the remaining RubySpecs, but sacrificing performance is not an option, so benchmarking is a big part of the work: ``` $ bundle exec rake bench:report Benchmark Opal1 Opal2 Opal3 Opal4 Ruby1 /Users/vais/Desktop/benchmark/bm_hash_assoc_object.rb 0.675 0.915 0.822 0.836 0.016 /Users/vais/Desktop/benchmark/bm_hash_assoc_string.rb 2.866 2.741 2.840 2.786 0.015 /Users/vais/Desktop/benchmark/bm_hash_clone_object.rb 1.710 2.070 1.849 1.846 0.690 /Users/vais/Desktop/benchmark/bm_hash_clone_string.rb 0.165 0.350 0.352 0.277 0.725 /Users/vais/Desktop/benchmark/bm_hash_delete_object.rb 0.746 0.179 0.208 0.121 0.016 /Users/vais/Desktop/benchmark/bm_hash_delete_string.rb 2.936 0.030 0.029 0.030 0.008 /Users/vais/Desktop/benchmark/bm_hash_each_key_object.rb 0.159 0.218 0.225 0.195 1.316 /Users/vais/Desktop/benchmark/bm_hash_each_key_string.rb 0.131 0.175 0.162 0.168 0.876 /Users/vais/Desktop/benchmark/bm_hash_each_object.rb 7.846 0.814 0.816 0.834 1.173 /Users/vais/Desktop/benchmark/bm_hash_each_string.rb 0.799 0.838 0.813 0.857 0.913 /Users/vais/Desktop/benchmark/bm_hash_each_value_object.rb 6.721 0.268 0.268 0.261 1.085 /Users/vais/Desktop/benchmark/bm_hash_each_value_string.rb 0.199 0.194 0.203 0.200 0.866 /Users/vais/Desktop/benchmark/bm_hash_element_reference_object.rb 0.126 0.214 0.208 0.179 0.014 /Users/vais/Desktop/benchmark/bm_hash_element_reference_string.rb 0.017 0.018 0.021 0.019 0.011 /Users/vais/Desktop/benchmark/bm_hash_element_set_object.rb 0.406 0.837 0.645 0.728 0.102 /Users/vais/Desktop/benchmark/bm_hash_element_set_string.rb 0.130 0.141 0.127 0.146 0.068 /Users/vais/Desktop/benchmark/bm_hash_equal_value_object.rb 11.988 10.678 9.553 9.771 2.980 /Users/vais/Desktop/benchmark/bm_hash_equal_value_string.rb 2.387 0.214 0.231 0.223 1.227 /Users/vais/Desktop/benchmark/bm_hash_fetch_object.rb 0.098 0.115 0.107 0.110 0.008 /Users/vais/Desktop/benchmark/bm_hash_fetch_string.rb 0.014 0.014 0.019 0.014 0.013 /Users/vais/Desktop/benchmark/bm_hash_flatten_object.rb 6.994 0.233 0.212 0.228 0.780 /Users/vais/Desktop/benchmark/bm_hash_flatten_string.rb 0.252 0.262 0.251 0.252 0.677 /Users/vais/Desktop/benchmark/bm_hash_has_key_object.rb 11.334 0.125 0.115 0.110 0.012 /Users/vais/Desktop/benchmark/bm_hash_has_key_string.rb 14.081 0.020 0.021 0.018 0.007 /Users/vais/Desktop/benchmark/bm_hash_has_value_object.rb 0.800 0.228 0.226 0.226 0.095 /Users/vais/Desktop/benchmark/bm_hash_has_value_string.rb 0.173 0.120 0.125 0.125 0.044 /Users/vais/Desktop/benchmark/bm_hash_hash_object.rb 2.293 2.080 2.086 2.122 0.039 /Users/vais/Desktop/benchmark/bm_hash_hash_string.rb 1.902 1.810 1.836 1.862 0.042 /Users/vais/Desktop/benchmark/bm_hash_inspect_object.rb 2.946 1.794 1.459 1.611 4.441 /Users/vais/Desktop/benchmark/bm_hash_inspect_string.rb 1.417 1.208 1.245 1.440 0.940 ... ``` ---------------------------------------------------------------------------------------------------- [13:06:55] Vais Salikhov(@vais):`Ruby1` column on the far right is MRI.

You might need a Crystal server and a separate "asset" server that's still Ruby. ---------------------------------------------------------------------------------------------------- [15:45:53] ylluminate(@ylluminate):on the topic of crystal, i'm curious as to what you guys see as the real appeal at the moment for the language as far as using opal with it. wouldn't this be more akin to a ruby + coffeescript scenario (where crystal is the coffeescript, but is more ruby-like obviously)? from what i've understood, it's not syntactically a one-to-one relationship with ruby; while it has obvious (serious) performance advantages, it does introduce a quirky relationship where we can't just run gems out of the box, etc... ---------------------------------------------------------------------------------------------------- [15:56:32] Jared White(@jaredcwhite):@ylluminate The way I see it, the #1 reason people ditch Ruby on Rails as a web stack is performance. First you ditch it in client-world by using frontend frameworks in a single page app (SPA). Then you ditch it in server-world by building APIs in some other language (JS/Node, Go, etc.) But if you are building SPAs in Javascript, Go, etc., well that's no fun! What if we could use Ruby/Ruby-like languages for both frontend and backend dev with great performance? Seems like a win/win scenario. (Of course, there are valid arguments to be made that Rails really isn't that big of a performance problem for most webapps...Improvements to MRI in 2.2+, or switching to JRuby, using the latest app servers like Passenger 5, etc...and there are even arguments to be made that a more backend-focused approach with things like Turbolinks for frontend responsiveness are also decent solutions.) ---------------------------------------------------------------------------------------------------- [15:57:19] Jared White(@jaredcwhite):But, y'know, NEW HOTNESS! :) ---------------------------------------------------------------------------------------------------- [16:20:01] ylluminate(@ylluminate):well that is my concern. raptor (passenger 5) has been amazing for us and i don't see the practicality of a loss of producitivity shifting to crystal, but i can see the "new hotness" argument, sure. ---------------------------------------------------------------------------------------------------- [16:21:13] ylluminate(@ylluminate):i could see a volt-like framework called "crystal-meth" that evokes the power of opal for the client side... ;) ---------------------------------------------------------------------------------------------------- [16:21:58] Forrest Chang(@fkchang):@ylluminate in my playing w/crystal thus far, I see it as a "subset of ruby" that ends up faster and w/smaller binaries than go. So my 1st thought is that I want to evangelize crystal as something rubyist can and should use in lieu of those times you would switch to golang or node -- which is generally performance based. That crystal makes binaries, and thus shippable w/o installing anything is an orthogonal perk. That being said, depending on the ruby you write, crystal will compile it directly, I grabbed some ruby mandelbrot code and it ran w/o modification - so I think constraining to a certain subset of ruby could work w/crystal in the backend. Since w/opal there are also things you have to do that don't work the same on the backend w/MRI or JRuby, I don't know if it would be that much of a change. That being said, crystal is still pretty early. I tried to get a simple websocket example working (that I want to hit on the front end from opal), and it turns out there's a fix or 2 that needs to get in for that to work. But, Crystal is also the only static language I can think of that has open classes, so I was able to monkey patch in the fixes w/o having clone, change and recompile crystal. We also spiked another application that uses JSON, which we encountered some issues. That might have some hinderances wrt to using crystal for webwork given the ubiquity of JSON, though hopefullly our issue on crystal will get some changes ---------------------------------------------------------------------------------------------------- [16:22:24] Forrest Chang(@fkchang):Ultimately, if I can basically write Ruby and have it run as fast as golang, I'm pretty happy. ---------------------------------------------------------------------------------------------------- [16:24:00] Forrest Chang(@fkchang):@jaredcwhite I suppose what @elia is suggesting is that that I use opal/sprockets rake task to do the compilation (possibly running under guard -- this is basically how people use grunt to do the equivalent of asset pipeline, set up the rules for grunt and then have it watch the source files) ---------------------------------------------------------------------------------------------------- [16:24:27] Forrest Chang(@fkchang):That's probably a good 1st step in lieu of trying to implement asset pipeline directly in crystal ---------------------------------------------------------------------------------------------------- [16:29:46] Forrest Chang(@fkchang):@ylluminate good name crystal-meth, if only we could get some sort of opal reference into it too ---------------------------------------------------------------------------------------------------- [16:33:03] ylluminate(@ylluminate):there's no doubt that that name is memorable and would certainly catch eyes ---------------------------------------------------------------------------------------------------- [16:34:42] ylluminate(@ylluminate):it sounds like a fork of volt to use crystal that would mutually contribute would perhaps be beneficial and act as a healthy boon to the effort of volt. volt would be the pure ruby stack, meth would be the crystal stack version with the same opal effort going on ---------------------------------------------------------------------------------------------------- [16:36:06] ylluminate(@ylluminate):the idea of "hotness" is indeed accurate in that it's getting attention for the reasons noted, even though the practicality may be in question ---------------------------------------------------------------------------------------------------- [17:41:05] Elia Schito(@elia):As fun as it is the crystal-meth name I can see how it can raise issues like the cocaine gem did etc. Just a heads up ;) ---------------------------------------------------------------------------------------------------- [17:43:18] Elia Schito(@elia):For me crystal is being the solution to ship the agent for timesampler.com which so far was a gem nearly impossible to install for any non-ruby-developer. For I also tried a nw.js / atom-shell approach reusing nearly 100% of the code with Opal (which is a really cool project if you didn't know) but that too didn't end well, because you know… Node.js. ---------------------------------------------------------------------------------------------------- [17:44:38] Elia Schito(@elia):With crystal I almost finished porting the code with just its stdlib (+ the external fswatch) and I think that by tonight I can have a two executables shippable that I can easily wrap in an osx package and make people install it quite easily. ---------------------------------------------------------------------------------------------------- [17:55:59] ylluminate(@ylluminate):lol @elia the interesting point of crystal-meth is that it's not as confusing as something like `cocaine`. a gem named cociaine is kind of hard to grok and what's worse is that their description on rubygems is even worse: "A small library for doing (command) lines"... o.o Kinda odd and crazy, but meth is more akin to volt - well what does it mean? it doesn't matter per se because it's a framework and it's more about name recognition than describing what it is in the name for these framework cases. eg, rails doesn't necessarily make sense. you have to think about it quite a bit to pull in meaning, but the same could be said of methamphetamines as well - they, according to a quick google, release dopamine rapidly and thus create "reward, motivation, the experience of pleasure, and motor function" obviously it will be criticized, but it will definitely catch some positive attention as well in that perhaps it will shift the negatively connoted drug towards something more positive. lol... anywayzzz ;) ---------------------------------------------------------------------------------------------------- [18:13:14] Gabriel Rios(@gabrielrios):after seeing github remove a project for having word *retard* on it, It’s always good to have that in mind ---------------------------------------------------------------------------------------------------- [18:19:56] Elia Schito(@elia):@gabrielrios any link to the full story? I missed the drama this time… ---------------------------------------------------------------------------------------------------- [18:20:24] ylluminate(@ylluminate):just move to gitlab if needed... :D ---------------------------------------------------------------------------------------------------- [18:20:55] ylluminate(@ylluminate):this drama is getting disgustingly old ---------------------------------------------------------------------------------------------------- [18:21:20] ylluminate(@ylluminate):people are not "real" anymore unfortunately. too worried about things that absolutely shouldn't be made into mountains ---------------------------------------------------------------------------------------------------- [18:22:34] ylluminate(@ylluminate):i guess the next logical step for folks like this would be to make kids wear full body armor when playing soccer or perhaps just shutting down any and all social interaction for risk of being offended or dealing with potentially being offended ---------------------------------------------------------------------------------------------------- [18:22:53] Elia Schito(@elia):@gabrielrios nvm found it ---------------------------------------------------------------------------------------------------- [18:24:05] Gabriel Rios(@gabrielrios):@elia :+1: ---------------------------------------------------------------------------------------------------- [18:28:34] Forrest Chang(@fkchang):@elia cool beans on the installer. About how much work was it to port? ---------------------------------------------------------------------------------------------------- [18:29:04] Forrest Chang(@fkchang):The big drawback for crystal performance wise, is that we're in nearly the same boat as node was before npm took off, that we'd have to port all these gems ---------------------------------------------------------------------------------------------------- [18:29:10] Forrest Chang(@fkchang):or the functional equivalent ---------------------------------------------------------------------------------------------------- [18:38:38] ylluminate(@ylluminate):so what i'm gathering, there's no pkg mgmt tool for crystal yet, right? ---------------------------------------------------------------------------------------------------- [18:38:57] ylluminate(@ylluminate):that is a pretty big negative and not considering somehow tying in gems in any fashion is a huge loss ---------------------------------------------------------------------------------------------------- [18:40:03] ylluminate(@ylluminate):it might be smart if someone were to take rubygems and extend it with a crystal validator that would check projects to see if they're usable in crystal. it could be a simply badge on rubygems.org and could help project owners who are interested to be aware of that ---------------------------------------------------------------------------------------------------- [19:02:28] Elia Schito(@elia):Given Crystal is 95% ruby syntax I don't think it's that easy to port entire gems, probably more difficult than porting to Opal as a bunch of semantics change as well ---------------------------------------------------------------------------------------------------- [19:03:27] ylluminate(@ylluminate):well, i guess i'm saying that it would make sense to have a way to test and then perhaps have a mechanism in place to make gems both std ruby and crystal compliant; perhaps having some .cr.diff files or something. brainstorming obviously. ---------------------------------------------------------------------------------------------------- [19:04:37] Elia Schito(@elia):Sure would be cool to use crystal instead of c for ruby extensions ---------------------------------------------------------------------------------------------------- [19:07:12] Elia Schito(@elia):@fkchang I think around 3hrs so far ---------------------------------------------------------------------------------------------------- [19:21:09] Forrest Chang(@fkchang):@ylluminate I haven't figured out the shards thing yet, but it seems that you setup the equivalent of a Gemfile with links right to repos (which I have to guess is in the shard format), and it will include those -- sort of a built in bundler. No central repository outside of github ATM, from what I can tell ---------------------------------------------------------------------------------------------------- [20:05:56] Mitch VanDuyn(@catmando): Folks - Anyway "reinitialize" opal? Am working on some server side rendering with RubyRacer, and want to avoid recreating the RubyRacer context if at all possible. This would require (I think) some how reinitializing Opal... any ideas? ---------------------------------------------------------------------------------------------------- [22:01:51] Forrest Chang(@fkchang):I think one think I like about asset pipeline in the app is that you get compile errors in the app. I think I should hope to understand that better, because I'd like to catch opal-rspec compile errors in the app, but what happens is that opal-rspec just doesn't run the spec that has compile errors, and you get fooled unless you watch the spec count. @elia have u or @adambeynon given thought to that? ---------------------------------------------------------------------------------------------------- [22:03:42] Elia Schito(@elia):@catmando that depends on what get's "dirty", anyway Opal it's enough similar to Ruby to make it quite difficult I think ---------------------------------------------------------------------------------------------------- [22:04:48] Elia Schito(@elia):@fkchang that's probably just related to the server running in a thread (or fork) and thus swalloing errors without feedback, try opening an issue for that ---------------------------------------------------------------------------------------------------- [22:25:12] Rick Carlino(@RickCarlino):Many opal gems call `.untaint` when adding themselves to the file path. Why is that? ---------------------------------------------------------------------------------------------------- [22:26:05] Elia Schito(@elia):Because some people used tainting features in their setup, like $SAFE = some number ---------------------------------------------------------------------------------------------------- [22:26:24] Rick Carlino(@RickCarlino):Ah ---------------------------------------------------------------------------------------------------- [22:44:30] Forrest Chang(@fkchang):@elia it happens when you hit spec page in the rails app too, I'm pretty certain. When I get a chance to verify, I'll write an issue.

It could be the right combiniation: Rails, opal and React since it is getting a lot of favorable press ---------------------------------------------------------------------------------------------------- [15:15:16] Elia Schito(@elia):@bbatsov "Used in production by 2013" actually just checked and the first time I used it was 26 june 2013 ---------------------------------------------------------------------------------------------------- [15:15:59] Elia Schito(@elia):implementing some frontend filters for an e-commerce ---------------------------------------------------------------------------------------------------- [15:16:13] Bozhidar Batsov(@bbatsov):I watched @fkchang’s presentation and he mentioned that he knew of some apps using it in prod in 2013 ---------------------------------------------------------------------------------------------------- [15:16:24] Bozhidar Batsov(@bbatsov):therefore this particular date reference ---------------------------------------------------------------------------------------------------- [15:17:23] Bozhidar Batsov(@bbatsov):btw, when I was at the conference some people were wondering how to get involved in the development ---------------------------------------------------------------------------------------------------- [15:17:38] Bozhidar Batsov(@bbatsov):it might be good to start adding “beginner-friendly” tags to some tickets ---------------------------------------------------------------------------------------------------- [15:17:46] Elia Schito(@elia):yeah, was just for info :) ---------------------------------------------------------------------------------------------------- [15:18:04] Bozhidar Batsov(@bbatsov):and perhaps link straight from the README to the list of things that have to be implemented ---------------------------------------------------------------------------------------------------- [15:18:12] Elia Schito(@elia)::+1: seems a good idea ---------------------------------------------------------------------------------------------------- [15:19:19] Elia Schito(@elia):If you happen to see any issue that can be marked as such just drop a comment and I'll add the tag ---------------------------------------------------------------------------------------------------- [15:20:05] Jared White(@jaredcwhite):hey folks - just a heads up that I'm putting the next Opalist issue off until next week - (a) I'm buried in work this week, and (b) the usual volume of news is a little less than usual by this time, but I'm sure next week there will be plenty to talk about. @catmando Hugely excited about what you shared on the React + Opal stuff your team is working on.

Maybe I can outsource it to @RickCarlino aka "God of opal screencasts" (GOOS from now on) ---------------------------------------------------------------------------------------------------- [15:25:01] Forrest Chang(@fkchang):I can be Maverick to his 'Goos', but I'll have to level up my (nonexistant) screencast game ---------------------------------------------------------------------------------------------------- [15:56:39] CJ Lazell(@cj):opal uses sprockets 3 now right? ---------------------------------------------------------------------------------------------------- [16:02:17] Forrest Chang(@fkchang):@cj as of 0.8 yes ---------------------------------------------------------------------------------------------------- [16:02:39] CJ Lazell(@cj):dang, they dropped gzip support in 3 ---------------------------------------------------------------------------------------------------- [16:04:25] CJ Lazell(@cj):I guess I’ll have to patch it :) ---------------------------------------------------------------------------------------------------- [17:25:55] Forrest Chang(@fkchang):@cj yeah, can't upgrade opal-playground coz middleman doesn't support sprockets 3, which is how opal-playground is setup ---------------------------------------------------------------------------------------------------- [19:59:54] AstonJ(@AstonJ):Nice slides @bbatsov - just posted on MR http://metaruby.com/t/if-youre-not-into-opal-how-can-we-convince-you/36/6 :) ---------------------------------------------------------------------------------------------------- [20:08:12] AstonJ(@AstonJ):@catmando - that was a great post, thanks… I tweeted it too :D ---------------------------------------------------------------------------------------------------- [20:16:02] Mitch VanDuyn(@catmando):I guess I am wondering what the arguments are that we see AGAINST using opal. (thanks @fkchang and @astonj for the encouragement, and @dancinglightning for trying out the system and making some great suggestions) ---------------------------------------------------------------------------------------------------- [20:44:35] AstonJ(@AstonJ):We touched on it in this thread @catmando http://metaruby.com/t/why-are-you-using-opal/258 - I think a big part is down to lack of official documentation.

My timezone is +10, so out of sync with your conversation. I understand your concern to keep the API clean and consistent, but I’ll probably keep my little patch going as it saves a lot of repetitive and comparatively untidy code. Since `#alias_native` already provides an `:as` option to provide type conversion from the native object, having the additional option `:as_array_of` seems to me semantically and functionally consistent with the intent of the method, and is very handy and concise to boot.

To do this rails-react looks for a components.js file that should require all the components to be loaded into V8 for prerendering. So in 0.7 I simply required 'opal' plus any other gems that I was using as well as the actual components. All worked fine. In 0.8 here is what I see (poking with the debugger and the rubyracer interface into the JS engine) : Opal seems to have been loaded fine, but the rest of the requires are simply not there. Other normal JS code in the components.js file after the requires executes just fine. I am wondering if the way loading and requires has changed somehow and I have to do something more to get all this required code to have been actually loaded into the Opal name space? Thanks in advance. ---------------------------------------------------------------------------------------------------- [10:41:35] Elia Schito(@elia):@catmando Try with `Opal.require('application')` where `application` is the name of your main file ---------------------------------------------------------------------------------------------------- [11:10:56] Mitch VanDuyn(@catmando):I tried with load and that helps.

Not responding, no output, asks to kill the page after a while.

Opal -c says some file not found (doesn’t say which, but i guess salama) ---------------------------------------------------------------------------------------------------- [13:59:02] meh.(@meh):dancinglightning, then download the generate .js and upload it somewhere ---------------------------------------------------------------------------------------------------- [13:59:08] meh.(@meh):I just need the compile blob ---------------------------------------------------------------------------------------------------- [13:59:15] meh.(@meh):or if you're using opal server and chrome ---------------------------------------------------------------------------------------------------- [13:59:21] meh.(@meh):open the developer tools ---------------------------------------------------------------------------------------------------- [13:59:24] meh.(@meh):in the debugger there's a pause icon ---------------------------------------------------------------------------------------------------- [13:59:26] meh.(@meh):click that ---------------------------------------------------------------------------------------------------- [13:59:32] meh.(@meh):and it should stop the execution and start the debugger in there ---------------------------------------------------------------------------------------------------- [14:00:04] meh.(@meh):but since it could be a bug somewhere outside StringScanner ---------------------------------------------------------------------------------------------------- [14:00:14] meh.(@meh):giving me the blob would be a better idea, or making a repo to make it run myself ---------------------------------------------------------------------------------------------------- [14:00:27] Torsten Rüger(@dancinglightning):@meh i never get to a page to open dev tools, it just hangs. I can check in and you can clone ---------------------------------------------------------------------------------------------------- [14:00:35] meh.(@meh):fine by me ---------------------------------------------------------------------------------------------------- [14:18:08] Torsten Rüger(@dancinglightning):@meh it’s done https://github.com/salama/salama-debugger on branch diy-render . Please understand that i was in the middle of an experiment there and the app doesn’t actually do anything. But it’s pure opal (as opposed to master which is volt) and has the bug in there. Possibly creating a simple app with just salama-reader is simpler for you. Still, good luck ---------------------------------------------------------------------------------------------------- [15:07:35] meh.(@meh):dancinglightning, ok, I reduced it to a loop in Parslet::Atoms::Repetition#try ---------------------------------------------------------------------------------------------------- [15:07:53] meh.(@meh):now I just have to figure out what alignment of stars causes it to explode ---------------------------------------------------------------------------------------------------- [15:08:07] meh.(@meh):because a basic parslet parser is working ---------------------------------------------------------------------------------------------------- [15:08:11] meh.(@meh):guess that's something ---------------------------------------------------------------------------------------------------- [15:18:16] Torsten Rüger(@dancinglightning):meh can you run parslets own tests under opal? ---------------------------------------------------------------------------------------------------- [15:19:21] meh.(@meh):I think that would be hard ---------------------------------------------------------------------------------------------------- [15:20:58] Torsten Rüger(@dancinglightning):My grammar may be kind of sub optimal for testing.

I don’t think it’s far off. ---------------------------------------------------------------------------------------------------- [16:40:23] meh.(@meh):dancinglightning, it's either a compiler bug, or a bug in StringScanner ---------------------------------------------------------------------------------------------------- [16:40:28] meh.(@meh):but it's probably the former :( ---------------------------------------------------------------------------------------------------- [16:40:39] meh.(@meh):the compiler is a total mess ---------------------------------------------------------------------------------------------------- [01:27:57] meh.(@meh):@dancinglightning can you test parslet works without the blankslate removal on master please? ---------------------------------------------------------------------------------------------------- [01:28:16] meh.(@meh):unless I'm dumb and that wasn't you ---------------------------------------------------------------------------------------------------- [01:29:59] meh.(@meh):mh, nope, blocked by exist ---------------------------------------------------------------------------------------------------- [02:34:56] meh.(@meh):@dancinglightning yeah, no luck, there's another compilation issue ---------------------------------------------------------------------------------------------------- [02:35:51] meh.(@meh):@dancinglightning at least I added the missing StringScanner methods :P ---------------------------------------------------------------------------------------------------- [11:14:44] Martin Becker(@Thermatix):could I have some clarification regarding inheritance please? I have a base class: ```ruby class Base include React::Component def initialize(native) @native = native end end ``` ---------------------------------------------------------------------------------------------------- [11:15:39] Martin Becker(@Thermatix):and then an app class: ```ruby class App < Base define_state(:logged_in) {:false} end ---------------------------------------------------------------------------------------------------- [11:15:54] Martin Becker(@Thermatix):``` (whoops) ---------------------------------------------------------------------------------------------------- [11:16:40] Martin Becker(@Thermatix):it complains Uncaught NoMethodError: undefined method `define_state' for # ---------------------------------------------------------------------------------------------------- [11:17:01] Martin Becker(@Thermatix):shouldn't it have access to `define_state`? ---------------------------------------------------------------------------------------------------- [11:17:11] Elia Schito(@elia):is define_state defined in the superclass (Base)? ---------------------------------------------------------------------------------------------------- [11:17:26] Martin Becker(@Thermatix):it's included from `include React::Component` ---------------------------------------------------------------------------------------------------- [11:17:41] Elia Schito(@elia):could be a bug ---------------------------------------------------------------------------------------------------- [11:17:49] Martin Becker(@Thermatix):since I was doing it in every class, I thought it easier to do that in a base class and then just inherit form base ---------------------------------------------------------------------------------------------------- [11:19:49] Martin Becker(@Thermatix):specificly I have `define_state(:logged_in) {:false}` inside of ```ruby before_mount do define_state(:logged_in) {:false} end ``` ---------------------------------------------------------------------------------------------------- [11:20:00] Martin Becker(@Thermatix):which is where the error is happening ---------------------------------------------------------------------------------------------------- [11:20:17] Elia Schito(@elia):which opal version? ---------------------------------------------------------------------------------------------------- [11:20:35] Martin Becker(@Thermatix):"~> 0.8" ---------------------------------------------------------------------------------------------------- [11:20:45] Elia Schito(@elia):also, does it work outside of the block? ---------------------------------------------------------------------------------------------------- [11:22:42] Martin Becker(@Thermatix):one moment, having weird issue, need to reset-server ---------------------------------------------------------------------------------------------------- [11:25:09] Martin Becker(@Thermatix):huh ---------------------------------------------------------------------------------------------------- [11:25:39] Martin Becker(@Thermatix):ok so I moved them out of the before_mount block and now it's sorta working? I mean the error's differant and just as oodd but the "undefined method" has gone away ---------------------------------------------------------------------------------------------------- [11:25:44] Martin Becker(@Thermatix):I guess it's a bug with react.rb ---------------------------------------------------------------------------------------------------- [11:32:23] Martin Becker(@Thermatix):so yeah, moving the `define_state` out of the `before_mount` block makes the problem go away, the current problem is a validation issue, something unrelated. ---------------------------------------------------------------------------------------------------- [11:32:51] Martin Becker(@Thermatix):guess I'll go bug them then, thanks ---------------------------------------------------------------------------------------------------- [11:33:19] Elia Schito(@elia)::+1: ---------------------------------------------------------------------------------------------------- [11:46:52] Martin Becker(@Thermatix):Actually, I take it back, It has to be in a `before_mount block` the problem is weird though, It says that it's undefined for `App` but the actual code that causes the problem is in a separate class called `Spinner`. It's very odd ---------------------------------------------------------------------------------------------------- [11:52:24] meh.(@meh):Thermatix, can you try on master? ---------------------------------------------------------------------------------------------------- [11:55:03] Martin Becker(@Thermatix):which version is master? ---------------------------------------------------------------------------------------------------- [11:55:58] Martin Becker(@Thermatix):nvm I'll clone and install it ---------------------------------------------------------------------------------------------------- [12:01:33] Martin Becker(@Thermatix):Ok, just updated to v0.9.0-dev ---------------------------------------------------------------------------------------------------- [12:01:38] Martin Becker(@Thermatix):and it's still complaining ---------------------------------------------------------------------------------------------------- [12:02:18] Martin Becker(@Thermatix):huh, is it me or is the backtrace in the JS console more human readable? ---------------------------------------------------------------------------------------------------- [12:05:21] Martin Becker(@Thermatix):no wait, it is just me, I've been using the .min version >_< ---------------------------------------------------------------------------------------------------- [12:06:05] meh.(@meh):Thermatix, can you make a simple repo that showcases the problem? ---------------------------------------------------------------------------------------------------- [12:06:19] meh.(@meh):so I can try and see if it's an Opal issue or not ---------------------------------------------------------------------------------------------------- [12:09:34] Martin Becker(@Thermatix):ok, give me a moment ---------------------------------------------------------------------------------------------------- [12:29:06] Martin Becker(@Thermatix):https://github.com/Thermatix/sprockets_problem and then switch to branch "undefined_method_define_state" ---------------------------------------------------------------------------------------------------- [12:29:31] Martin Becker(@Thermatix):follow the notes ---------------------------------------------------------------------------------------------------- [12:29:39] Martin Becker(@Thermatix):and then just run ./executable ---------------------------------------------------------------------------------------------------- [12:29:51] Martin Becker(@Thermatix):afk, need foooods ---------------------------------------------------------------------------------------------------- [12:43:37] Martin Becker(@Thermatix):back ---------------------------------------------------------------------------------------------------- [12:57:54] Mitch VanDuyn(@catmando):@thermatix - pretty sure this is a react.rb issue - lets move it over there... ---------------------------------------------------------------------------------------------------- [12:58:28] meh.(@meh):catmando, yeah ---------------------------------------------------------------------------------------------------- [12:58:30] meh.(@meh):I've been digging ---------------------------------------------------------------------------------------------------- [12:58:33] meh.(@meh):App does not have define_state ---------------------------------------------------------------------------------------------------- [12:58:36] Torsten Rüger(@dancinglightning):@meh nice, that scanner method got me a step closer.

You could try to investigate https://github.com/bwl21/zupfnoter/blob/master/30_sources/SRC_Zupfnoter/src/controller-nw.rb This is all I did to integrate. You can see the Rakefile https://github.com/bwl21/zupfnoter/blob/master/30_sources/SRC_Zupfnoter/src/Rakefile line 86 ff is the rake task to build the apps. ---------------------------------------------------------------------------------------------------- [10:21:05] Torsten Rüger(@dancinglightning):@elia i think documentation improvements are good, but opalrb.org is where people are most likely to land, i would start by improving that ---------------------------------------------------------------------------------------------------- [21:38:04] Qqwy / Wiebe-Marten(@Qqwy):@bwl21 : That looks great. ---------------------------------------------------------------------------------------------------- [21:38:07] Qqwy / Wiebe-Marten(@Qqwy):I will try to get it to run ---------------------------------------------------------------------------------------------------- [21:38:30] Qqwy / Wiebe-Marten(@Qqwy):I myself am not that far yet; Right now I'm attempting to include opal-jquery to no avail ---------------------------------------------------------------------------------------------------- [21:40:21] Qqwy / Wiebe-Marten(@Qqwy):In the task file where I call Opal.compile() I have `require 'opal'` and `require 'opal-jquery'`.

The npm request package allows you to get content from a remote URL (without relying on AJAX). It is usually used as follows: ---------------------------------------------------------------------------------------------------- [21:38:35] Qqwy / Wiebe-Marten(@Qqwy):request('http://example.com', function(error, response, body){ /* Do something with the result here */}) ---------------------------------------------------------------------------------------------------- [21:39:18] Qqwy / Wiebe-Marten(@Qqwy):Where `body` will contain the body of the HTTP response, `response` contains the headers and other metadata and `error` is empty unless there was a problem, in which case it is an array, iirc. ---------------------------------------------------------------------------------------------------- [21:40:21] Qqwy / Wiebe-Marten(@Qqwy):Basically I want to grab the results (that are gathered asynchroniously as everything is -for better or worse- in Node, and call a Ruby block with it ---------------------------------------------------------------------------------------------------- [21:43:30] meh.(@meh):well ---------------------------------------------------------------------------------------------------- [21:43:34] meh.(@meh):a Ruby block is just a JS function ---------------------------------------------------------------------------------------------------- [21:44:51] Qqwy / Wiebe-Marten(@Qqwy):Wait, so I can just pass it's name inside a #{} ? ---------------------------------------------------------------------------------------------------- [21:45:05] meh.(@meh):yeah ---------------------------------------------------------------------------------------------------- [21:45:16] Qqwy / Wiebe-Marten(@Qqwy):like `do_something_with_passed_function(#{ruby_block_name})` ? ---------------------------------------------------------------------------------------------------- [21:45:21] Qqwy / Wiebe-Marten(@Qqwy):Wow, awesome! ---------------------------------------------------------------------------------------------------- [21:45:23] meh.(@meh):yeah ---------------------------------------------------------------------------------------------------- [21:45:24] Qqwy / Wiebe-Marten(@Qqwy):It works! :D ---------------------------------------------------------------------------------------------------- [21:45:29] meh.(@meh):if you want the parameters to be wrapped in a native ---------------------------------------------------------------------------------------------------- [21:45:41] meh.(@meh):you can use `Native.proc { }` instead of `proc { }` ---------------------------------------------------------------------------------------------------- [21:52:52] Qqwy / Wiebe-Marten(@Qqwy):Is there documentation on the proper use of Native somewhere? ---------------------------------------------------------------------------------------------------- [21:53:28] meh.(@meh):I don't think so ---------------------------------------------------------------------------------------------------- [21:53:35] meh.(@meh):but the code is really small and self-contained ---------------------------------------------------------------------------------------------------- [22:09:07] Qqwy / Wiebe-Marten(@Qqwy):Where can I find the source code for Native? ---------------------------------------------------------------------------------------------------- [22:11:35] meh.(@meh):Qqwy, stdlib ---------------------------------------------------------------------------------------------------- ############################## [2015-08-25] ############################## [08:39:20] Martin Becker(@Thermatix):how do I use set_timeout or set_interval with opal? ---------------------------------------------------------------------------------------------------- [08:40:40] Martin Becker(@Thermatix):nvm , found it ---------------------------------------------------------------------------------------------------- [09:34:17] Bernhard Weichel(@bwl21):@Qqwy sorry, have been afk for a day. I have no clue, what is missing. My application does the same includes as you do. ---------------------------------------------------------------------------------------------------- [09:46:13] Bernhard Weichel(@bwl21):I need some help with object_id. I try to integrate a third party JS library which uses chained lists. I want to convert the same and there fore need unique object Ids. But if I call Native on the same JS-object twice, object_id does not yield the same result. ``` a = `{"foo": "hugo"}` puts Native(a).__id__ puts Native(a).__id__ puts Native(a).__id__ ``` yields 14522 14528 14532 I know there is no object id in JS. But is there any way that the code above always yields the same id? ---------------------------------------------------------------------------------------------------- [10:00:46] Martin Becker(@Thermatix):your going to have to store the results of `Native(a)` into a variable, it's generate new Ids because it's generate new objects each time you call Native(a). ---------------------------------------------------------------------------------------------------- [10:01:03] Martin Becker(@Thermatix):it's generating* ---------------------------------------------------------------------------------------------------- [10:01:28] Martin Becker(@Thermatix):They're not the same object hence differing ID's ---------------------------------------------------------------------------------------------------- [10:46:24] Bernhard Weichel(@bwl21):@Qqwy for a nw app, you still need to have a html landing page which embeds your script. Do you have that? ---------------------------------------------------------------------------------------------------- [10:49:33] Bernhard Weichel(@bwl21):@Thermatix this does not really help. I want to keep the JS-Objects in a hash and reference the same by the object id. So the only way I see is that the very first call to Native adds a unique Id to the underlying JS object. My question here is, if someone has already implemented such an approach. ---------------------------------------------------------------------------------------------------- [10:49:57] Martin Becker(@Thermatix):I mean like this ---------------------------------------------------------------------------------------------------- [10:50:54] Martin Becker(@Thermatix):```ruby a = `{"foo": "hugo"}` natives = {} natives[:a] = Native(a) puts natives[:a].__id__ ``` ---------------------------------------------------------------------------------------------------- [10:56:55] Bernhard Weichel(@bwl21):Yes but now I would like to see if natives already contains object a ---------------------------------------------------------------------------------------------------- [11:08:50] Martin Becker(@Thermatix):```ruby class Natives @natives = {} def add key,value @natives[key] = value unless not_allowed? value end def get key @natives[key] end def not_allowed? value get(key).__id__ == value.__id__ end end ---------------------------------------------------------------------------------------------------- [11:09:05] Martin Becker(@Thermatix):ug ---------------------------------------------------------------------------------------------------- [11:09:07] Martin Becker(@Thermatix):```ruby class Natives @natives = {} def add key,value @natives[key] = value unless not_allowed? value end def get key @natives[key] end def not_allowed? value get(key).__id__ == value.__id__ end end ``` ---------------------------------------------------------------------------------------------------- [11:09:33] Martin Becker(@Thermatix):oops, wrong class name but that might be the closest your gonnah get ---------------------------------------------------------------------------------------------------- [11:09:39] Martin Becker(@Thermatix):the problem is that ---------------------------------------------------------------------------------------------------- [11:10:48] Martin Becker(@Thermatix):`Natives(a)` generates a different object with the same keys each time, so you need to check if a key exists not an id (ofcourse not what i've done) ---------------------------------------------------------------------------------------------------- [11:36:00] Bernhard Weichel(@bwl21):Tried here: http://opalrb.org/try/?code:%20%20%20%20class%20Native%0A%20%20%20%20%20%20%20%20%40natives%20%3D%20%7B%7D%0A%20%20%20%20%20%20%20%20def%20add%20key%2Cvalue%0A%20%20%20%20%20%20%20%20%20%20%20%20%40natives%5Bkey%5D%20%3D%20value%20unless%20not_allowed%3F%20value%0A%20%20%20%20%20%20%20%20end%0A%0A%20%20%20%20%20%20%20%20def%20get%20key%0A%20%20%20%20%20%20%20%20%20%20%20%20%40natives%5Bkey%5D%0A%20%20%20%20%20%20%20%20end%0A%0A%20%20%20%20%20%20%20%20def%20not_allowed%3F%20value%0A%20%20%20%20%20%20%20%20%20%20%20%20get(key).__id__%20%3D%3D%20value.__id__%20%0A%20%20%20%20%20%20%20%20end%0A%20%20%20%20end%0A%0Aa%20%3D%20%60%7B%22foo%22%3A%20%22hugo%22%7D%60%0Ab%20%3D%20%60%7B%22foo%22%3A%20%22hugo%22%7D%60%0A%0A%0A%0Ax%20%3D%20Native(a)%0Ay%20%3D%20Native(a)%0Az%20%3D%20Native(b)%0A%0A%0Aputs%20x.get_key%0Aputs%20y.get_key%0Aputs%20z.get_key%0A%0A%20%20 ---------------------------------------------------------------------------------------------------- [11:36:35] Bernhard Weichel(@bwl21):But I wonder where the __id__ is added to the JS object. ---------------------------------------------------------------------------------------------------- [11:38:26] Bernhard Weichel(@bwl21):I guess your appraoch is to add an id to the JS object on the very first invocation of Native(a) right? ---------------------------------------------------------------------------------------------------- [11:44:58] Martin Becker(@Thermatix):I made a few mistakes, just touching it up >_< ---------------------------------------------------------------------------------------------------- [11:50:38] Colin Gunn(@balmoral):@bwl21 Don’t know if this is what you need but have you tried wrapping the JS objects in a Ruby class with Native mixin: ``` class SomeClass include Native alias_native :id, :__id__ …. end def some_method ruby_object = SomeClass.new(js_native) puts ruby_object.id end ``` ---------------------------------------------------------------------------------------------------- [11:52:00] Colin Gunn(@balmoral):that way you’re not creating a new Native instance every time ---------------------------------------------------------------------------------------------------- [12:02:34] Bernhard Weichel(@bwl21):To summarize my issue: I have a bunch of linked JS objects. They are linked such that they have a prev and a next reference. If I want to serialize such an object to JSON, I get an endless loop. Therefore I want to replace prev and next by object ids and a hash which resolves these ids. In oder to do this I need to find out, if a given JS object is already in my hash. ---------------------------------------------------------------------------------------------------- [12:06:56] Martin Becker(@Thermatix):hmm ok i've tried a few ways to do it, but it won't work, as said, every time you do `Native(a)` it generates a new object, so doing that twice in row will generate a native object with a separate id each time because there not the same object even if the object used to generate the native is the same, the only way your going to store a native is to store the created native into a hash with a key and then use that key as a unique reference no other way I can see, that or try what @balmoral suggested ---------------------------------------------------------------------------------------------------- [12:08:31] Martin Becker(@Thermatix):btw how in react do I pass a value to component that isn't a prop,? I want to push something to a component but not as a prop, how would I do this? ---------------------------------------------------------------------------------------------------- [12:27:53] Bernhard Weichel(@bwl21):I need to take a break and be afk for a few hours. Maybe I get an entirely new idea ... The best would be if Native yields the same object for the same JS object. In other words, if Native generates the wrapper, it could place the __id__ property in the JS object. By this it could yield the same Native instance whenever an object of the same __id__ occurs. Of course this might cause problems with the garbage collector. The other option for me is to solve it not in the most generic way but utilizing the application knowledge and solve it on the application level. thanks so far for the discussion. ---------------------------------------------------------------------------------------------------- [12:45:14] Martin Becker(@Thermatix):sorry I wasn't much help ---------------------------------------------------------------------------------------------------- [15:01:35] Jamie Gaskins(@jgaskins):I started working last night on an idea for server-rendered components in Clearwater. It's as simple as this in an initializer: ``` Opal.append_paths(shared_components_path) ``` … where `shared_components_path` is where your isomorphic code lives, like `"app/shared"`. Then you can just put `<%= MyComponent.new %>` in your server-side view. I still need to add the ability to use the router on the server to handle routing targets (which will likely change how you put the component in your Rails views), but it works pretty well. The branch is here: https://github.com/clearwater-rb/clearwater/tree/server-render ---------------------------------------------------------------------------------------------------- [15:10:47] Adam Jahn(@ajjahn):@jgaskins, Yes! I love the idea of components that render on both sides of the wire. I recently played with @catmando's branch of react.rb that works with react-rails, and things just felt right. ---------------------------------------------------------------------------------------------------- [15:26:12] Bernhard Weichel(@bwl21):@Thermatix : what do you think about this: http://opalrb.org/try/?code:module%20Kernel%0A%20%20%20%20def%20Native(obj)%0A%20%20%20%20if%20%60%23%7Bobj%7D%20%3D%3D%20null%60%0A%20%20%20%20%20%20nil%0A%20%20%20%20elsif%20native%3F(obj)%0A%20%20%20%20%20%20result%20%3D%20%20Native%3A%3AObject.new(obj)%0A%20%20%20%20%20%20if%20%60typeof(%23%7Bobj%7D.__id__)%20!%3D%3D%20%27undefined%27%60%20%20%23%7Bobj%7D.__id__%20%7C%7C%200%60%20%3E%200%0A%20%20%20%20%20%20%20%20puts%20%22reusing%20object%20%23%7B%60%23%7Bobj%7D.__id__%60%7D%22%0A%20%20%20%20%20%20else%0A%20%20%20%20%20%20%20%20%60%23%7Bobj%7D.__id__%20%3D%20%23%7Bresult.__id__%7D%60%0A%20%20%20%20%20%20end%0A%20%20%20%20%20%20result%0A%20%20%20%20else%0A%20%20%20%20%20%20obj%0A%20%20%20%20end%0A%20%20end%0Aend%0A%0Aa%20%3D%20%60%7B%22foo%22%3A%20%22hugo%22%2C%20%22bar%22%3A%20%7B%22foobar%22%3A%20b%7D%7D%60%0Ab%20%3D%20%60%7B%22foo%22%3A%20a%7D%60%0A%0A%0A%0A%0Ax%20%3D%20Native(a)%0Ay%20%3D%20Native(a)%0Az%20%3D%20Native(b)%0Aw%20%3D%20z%0A%0A%0Aputs%20x%5B%3A__id__%5D%0Aputs%20y%5B%3A__id__%5D%0Aputs%20z%5B%3A__id__%5D%0Aputs%20z%5B%3Afoo%5D%5B%3A__id__%5D%0Aputs%20w%5B%3Afoo%5D%5B%3A__id__%5D%0A%0A%0A%20%20 @elia: could you also please have a look on this.

There's an object that Node makes that extends Node's EventEmitter. But I cannot figure out how to properly make the callbacks work with that ---------------------------------------------------------------------------------------------------- [22:59:52] Qqwy / Wiebe-Marten(@Qqwy):Is there a way to call methods on the native object directly? ---------------------------------------------------------------------------------------------------- [23:05:03] Qqwy / Wiebe-Marten(@Qqwy):A very simple example: ---------------------------------------------------------------------------------------------------- [23:05:18] Qqwy / Wiebe-Marten(@Qqwy):This is how EventEmitters work in Node: var EventEmitter = require('events').EventEmitter; var radium = new EventEmitter(); radium.on('radiation', function(ray) { console.log(ray); }); setInterval(function() { radium.emit('radiation', 'GAMMA'); }, 1000); ---------------------------------------------------------------------------------------------------- [23:06:09] Qqwy / Wiebe-Marten(@Qqwy):This is what I tried with Opal: `var EventEmitter = require('events').EventEmitter;` radium = Native(`new EventEmitter()`); radium.on('radiation')do |ray| console.log(ray); end `setInterval(function() {` radium.emit('radiation', 'GAMMA'); `}, 1000);` ---------------------------------------------------------------------------------------------------- [23:07:34] Qqwy / Wiebe-Marten(@Qqwy):The Opal code will never output anything on the console. ---------------------------------------------------------------------------------------------------- [15:37:43] Qqwy / Wiebe-Marten(@Qqwy):@bwl21 : Yes. I have a main page which has two script tags in its `head`: the latest jquery version and application.js, which is the compiled result of the Opal Builder. ---------------------------------------------------------------------------------------------------- [15:42:03] Qqwy / Wiebe-Marten(@Qqwy):The problem I have right now still is that Opal's `require` does not work for non-(.rb, .opal or .js) files ---------------------------------------------------------------------------------------------------- [15:43:31] Qqwy / Wiebe-Marten(@Qqwy):`require_tree 'app/views'` throws errors, as it can *see* files like `view.haml`, `item.haml` but then tries to load files called `view` and `item` (without any extension) ---------------------------------------------------------------------------------------------------- ############################## [2015-08-27] ############################## [02:26:56] Rick Carlino(@RickCarlino):Just bought my RubyConf tickets.

Replacing it with prettyprint does not solve the problem. Nor does something like Native.call(radium, 'on', 'radiation') do |ray| pp ray end change the outcome. ---------------------------------------------------------------------------------------------------- [12:54:08] Elia Schito(@elia):> @elia i think documentation improvements are good, but opalrb.org is where people are most likely to land, i would start by improving that ---------------------------------------------------------------------------------------------------- [12:55:26] Elia Schito(@elia):@dancinglightning the plan is to embed/link all docs guides into it, the difference would be they'd be available for different versions (similarly to what happens for rails) ---------------------------------------------------------------------------------------------------- [14:19:49] Bernhard Weichel(@bwl21):@Qqwy in my APP i use a Static compilation of the opal code.

Can Opal compile *itself* into JavaScript? ---------------------------------------------------------------------------------------------------- [07:19:01] Bernhard Weichel(@bwl21):@Qqwy wrt to event emitter: best is to implement a wrapper class for EventEmitter. ---------------------------------------------------------------------------------------------------- [07:19:56] Adam Beynon(@adambeynon):@gregc of course! We provide opal/parser.js which is the gem compiled by itself ---------------------------------------------------------------------------------------------------- [07:54:19] Bernhard Weichel(@bwl21):@Qqwy It is similar to this (did not test it): ``` class EventEmitter def initialize() %x{ var EventEmitter = require('events').EventEmitter; var #{@radium} = new EventEmitter(); } end def on(event, &block) Native(@radium).on(event, block) end def start %x{ setInterval(function() { #{@radium}.emit('radiation', 'GAMMA'); }, 1000); } end end e = EventEmitter.new e.on(:radiation) do |ray| puts ray end e.start ``` ---------------------------------------------------------------------------------------------------- [09:53:31] Forrest Chang(@fkchang):@meh what's the right way to do this in paggio? ```ruby Paggio.html! do |_| _.label({for: name}) {label} _.input.nbb({name: name, id: name, value: source, readonly: true}) end ``` I'm getting ``` {"name"=>"number-editor-1526", "id"=>"number-editor-1526", "value"=>"a", "readonly"=>true} ``` ---------------------------------------------------------------------------------------------------- [19:14:05] Qqwy / Wiebe-Marten(@Qqwy):@bwl21 Thank you very much for your help! Indeed it would be nice to build a wrapper around it. ---------------------------------------------------------------------------------------------------- [19:15:05] Qqwy / Wiebe-Marten(@Qqwy):As for the code you've posted above: The `Native(@radium).on(event, block)` construction ought to work, but sadly it does not. The only way I managed to make it work was: ---------------------------------------------------------------------------------------------------- [19:15:21] Qqwy / Wiebe-Marten(@Qqwy): def event_emitter_register_event(object, eventname, &block) `#{object}.on(#{eventname}, block)` end ---------------------------------------------------------------------------------------------------- [19:16:11] Qqwy / Wiebe-Marten(@Qqwy):This calls &block on the emission of the the 'eventname' event on the object. I would have expected the Native() element to work the same way, but alas, it did not ---------------------------------------------------------------------------------------------------- [19:17:05] Qqwy / Wiebe-Marten(@Qqwy):For now, when I need to listen to native Node events, I use this function. When creating my own, I use the ruby gem `events` which follows the Node EventEmitter syntax quite closely. ---------------------------------------------------------------------------------------------------- [20:01:20] Bernhard Weichel(@bwl21):@Qqwy AS i am in my table at the moment, it is too hard to enger code. But you could also add your JS code to the method, i proposed.

It probably wouldn't be as fast as C, but JS is pretty easy for the VM to optimize if you do things a certain way (or rather, _don't_ do things a certain way). Some of the biggest performance issues in Opal are caused by the Ruby language itself allowing (and sometimes depending on) behavior that can't be optimized inside the VM. ---------------------------------------------------------------------------------------------------- [11:52:17] Jamie Gaskins(@jgaskins):If someone wrote a Nokogiri-like gem mostly in JS and put a Ruby wrapper around it, it could probably perform pretty well. ---------------------------------------------------------------------------------------------------- [12:51:07] Elia Schito(@elia):@jgaskins require native first ---------------------------------------------------------------------------------------------------- [12:51:33] Elia Schito(@elia):(re hash.new) ---------------------------------------------------------------------------------------------------- [12:54:36] Elia Schito(@elia):@bigtunacan the opal CLI requires a file or -e eval code, but that shouldn't probably a requirement when using --compile, I can fix that for 0.9 ---------------------------------------------------------------------------------------------------- [12:59:59] Elia Schito(@elia):@jgaskins @ryanstout about Oga, I'm pretty sure we can provide our _small, native extension (JavaScript fo Opal)_ :smirk: ---------------------------------------------------------------------------------------------------- [15:26:59] Ilya Bylich(@iliabylich):Hi there.

I try to use a third party JS library. As soon as I combine it with Opal, it fails. I boiled it down to the fact that Opal extends the JS Array. The third party lib uses the `for (x in y)`to iterate over the array. Even if it is not a good practice, it is a problem. I can verify this with the following opal-Script ``` %x{ var a=[1,2,3]; for(x in a){ #{puts( `a[x]`)}; } } ``` This yields the array values together with the opal methods ... http://opalrb.org/try/?code:%25x%7B%0A%20%20%20var%20a%3D%5B1%2C2%2C3%5D%3B%0A%20%20%20for(x%20in%20a)%7B%0A%20%20%20%20%20%23%7Bputs(%20%60a%5Bx%5D%60)%7D%3B%0A%20%20%20%7D%0A%7D%0A%0A Any Idea how to overcome this issue without changing the third party lib. ---------------------------------------------------------------------------------------------------- [17:11:26] Gabriel Rios(@gabrielrios):@bwl21 no, this is a recurring issue, only way to solve this is change the third party lib, send them a PR ;) ---------------------------------------------------------------------------------------------------- [17:11:55] Gabriel Rios(@gabrielrios):#1024 #680 ---------------------------------------------------------------------------------------------------- [18:51:19] Mitch VanDuyn(@catmando):does anybody know if the opal compiler will remove lines surrounded in `if RUBY_ENGINE != 'opal'` for example: ---------------------------------------------------------------------------------------------------- [18:52:43] Mitch VanDuyn(@catmando):```ruby if RUBY_ENGINE != 'opal' # piles and piles of server side only code # can always do a conditional require, but is it necessary or does opal just # toss out the code inside the failed if? Clearly it is doing some optimization # at compile time otherwise requires would not work... end ``` ---------------------------------------------------------------------------------------------------- [19:18:34] Bernhard Weichel(@bwl21):@catmando I am afraid, it will still compile these lines, even if they will not be executed. But you will see compiler errors there if there are some. ---------------------------------------------------------------------------------------------------- [21:12:39] Jamie Gaskins(@jgaskins):@bwl21 @catmando: Well, kinda. It compiles the conditional, but doesn't put the code within it into the compiled output. ```ruby if RUBY_ENGINE != 'opal' puts 'DID OPAL COMPILE THIS?' end ``` ```javascript if ((($a = $scope.get('RUBY_ENGINE')['$!=']("opal")) !== nil && (!$a.$$is_boolean || $a == true))) {}; ``` ---------------------------------------------------------------------------------------------------- [21:15:04] Mitch VanDuyn(@catmando):@bw21 @jgaskins - not worried about compiler errors, just worried about dumping a load of code down to the browser that will never get executed. Looks like from @jgaskins example, no actual code is generated, which is very very cool. Will allow server and client side code to exist in one file, without impacting the client load time.

Some folks in the volt gitter were asking about it. ---------------------------------------------------------------------------------------------------- [19:33:34] Ryan Stout(@ryanstout):@jgaskins yea, great work everyone on performance stuff. The big bottleneck for me is code loading. I've spent a little time profiling, but haven't gotten anywhere. One I was thinking is maybe there's a way to detect that a class doesn't call any class methods (except for def's), and then basically lazy load the whole class in a function that gets called on the scope const lookup. I read that most of the browsers won't compile functions until they are first used, so using that, we could basically lazily compile all classes. (I think) ---------------------------------------------------------------------------------------------------- [19:40:28] Jamie Gaskins(@jgaskins):@ryanstout That sounds interesting. So something like this? ```javascript const_lookups = { "MyConst": function() { # Opal-compiled Ruby class definition goes here } } ``` And then `Kernel#const_missing` just pulls from that? ---------------------------------------------------------------------------------------------------- [19:42:04] Ryan Stout(@ryanstout):yea, basically. Opal has a $scope.get function (that calls const_missing if a class isn't defined, I think) ---------------------------------------------------------------------------------------------------- [19:42:41] Ryan Stout(@ryanstout):the compile time for opal is my biggest performance issue right now, and I'm thinking that its partly because too much code is being run at compile time. ---------------------------------------------------------------------------------------------------- [19:42:53] Ryan Stout(@ryanstout):(though take that with a grain of salt, I've only profiled a bit) ---------------------------------------------------------------------------------------------------- [19:45:52] Ryan Stout(@ryanstout):@jgaskins have you looked much at compile time for your stuff? (volt probably has more code, though its not a crazy amount or anything) ---------------------------------------------------------------------------------------------------- [19:50:29] Ryan Stout(@ryanstout):And by compile time, I mean time for the browser to "evaluate script" ---------------------------------------------------------------------------------------------------- [20:15:33] Jamie Gaskins(@jgaskins):@ryanstout About 2/3 of the Clearwater codebase is the [`virtual-dom`](https://github.com/Matt-Esch/virtual-dom) library (vendored for various reasons), which is a fair bit of code. I think it's about 500kb unminified in a Hello World app, but I would need to verify that since I usually look at minified/gzipped sizes. :-) ---------------------------------------------------------------------------------------------------- [20:16:42] Ryan Stout(@ryanstout):@jgaskins ok, cool. Yea, most of volt is opal stuff, except for jquery. So its probably more of an issue for me. Though the time right now is fine, I would just like it to be faster, hehe. ---------------------------------------------------------------------------------------------------- [20:29:12] Jamie Gaskins(@jgaskins):Dev load time in 0.8 on Rails is a little weird because it sends 200 or so requests, one for each Ruby file. And that's okay because it makes source maps work, but it is a little awkward to wait 2-3 seconds on every change. ---------------------------------------------------------------------------------------------------- [20:32:09] Jamie Gaskins(@jgaskins):I still have some work to do to figure out how to get things working right on Roda. It compiles just fine, but Roda (or Sprockets?) concatenates the files and that seems to break source maps. Also, if you view source on [my Clearwater/Roda demo app](https://clearwater-roda-example.herokuapp.com), the script it includes ends in `.rb` instead of `.js`, so I don't know what's going on there. :-) ---------------------------------------------------------------------------------------------------- [20:59:18] Elia Schito(@elia):@jgaskins @ryanstout if you find a way to concatenate sourcemaps reliably (as e.g. discourse does) I'm most intrested ---------------------------------------------------------------------------------------------------- [20:59:41] Ryan Stout(@ryanstout):@elia you still seeing sourcemap concat issues?

So when $scope.get is called, does that call the modules func if it hasn't been run yet? or thats on require? ---------------------------------------------------------------------------------------------------- [21:08:27] Elia Schito(@elia):autoload hooks into const_missing and performs a require automatically ---------------------------------------------------------------------------------------------------- [21:08:56] Elia Schito(@elia):this behavior should be the same in both Opal/CRuby ---------------------------------------------------------------------------------------------------- [21:09:34] Ryan Stout(@ryanstout):ok, but require calls the Opal.modules func when you require right? ---------------------------------------------------------------------------------------------------- [21:09:46] Ryan Stout(@ryanstout):(not using autoload ---------------------------------------------------------------------------------------------------- [21:09:47] Ryan Stout(@ryanstout):) ---------------------------------------------------------------------------------------------------- [21:10:27] Elia Schito(@elia):yes ---------------------------------------------------------------------------------------------------- [21:11:07] Ryan Stout(@ryanstout):ok ---------------------------------------------------------------------------------------------------- [21:11:18] Elia Schito(@elia):https://github.com/opal/opal/blob/master/opal/corelib/runtime.js#L1711-L1734 ---------------------------------------------------------------------------------------------------- [21:11:53] Elia Schito(@elia):`Kernel#requires` calls `Opal.require();` which calls `Opal.load();` ---------------------------------------------------------------------------------------------------- [21:11:55] Ryan Stout(@ryanstout):would it make since to make require delay and $scope.get load for classes that only have def's? ---------------------------------------------------------------------------------------------------- [21:12:03] Ryan Stout(@ryanstout):or am I missing something? ---------------------------------------------------------------------------------------------------- [21:13:16] Elia Schito(@elia):can you give me an example of how would that work? (not clear what you mean by classes with def's) ---------------------------------------------------------------------------------------------------- [21:16:57] Ryan Stout(@ryanstout):sure, so if I have a class like this: ```ruby class Blue def one 1 end end ``` The Blue class only has def's in it (no side effects). My goal would be to not compile the def's on the client if the Blue class never gets used. So for cases like above where the class only has methods in it (something fairly common in my code), you could flag the class somehow, then have the require not actually load the class yet. Then when opal does $scope.get, that function could see that the class isn't loaded yet and load it. Looking over the generated code from opal, corelib, and volt, there's probably 50% of classes that would fall into this category, and I think (though I could be wrong) that it would really speed up compile time. (Since again, a lot of classes in volt and corelib never get used) Since there's no way to do deadcode elimination, it would be another way to save some compile time in the browser. ---------------------------------------------------------------------------------------------------- [21:17:06] Ryan Stout(@ryanstout):let me know if that makes any since. ---------------------------------------------------------------------------------------------------- [21:19:25] Elia Schito(@elia):so you mean like some implicit autload that checks side effects? ---------------------------------------------------------------------------------------------------- [21:20:58] Elia Schito(@elia):For what I understand would still be better to use autoload explicitly as you can have eg. some `self.inherited` hooks that would count as side effects and are kinda hard to check statically ---------------------------------------------------------------------------------------------------- [21:21:30] Ryan Stout(@ryanstout):@elia cool, I didn't think about inherited ---------------------------------------------------------------------------------------------------- [21:21:50] Ryan Stout(@ryanstout):yea, I'm just hesitant to use autoload on the server.. I'll read up some more on it though. ---------------------------------------------------------------------------------------------------- [21:22:03] Elia Schito(@elia):@ryanstout anyway in theory is possible, but would require inspecting the AST and similar stuff… ---------------------------------------------------------------------------------------------------- [21:22:10] Ryan Stout(@ryanstout):@elia yea ---------------------------------------------------------------------------------------------------- [21:22:26] Ryan Stout(@ryanstout):well, maybe if I get some time, I'll try and throw something together and do some benchmarks ---------------------------------------------------------------------------------------------------- [21:22:33] Ryan Stout(@ryanstout):I'll check out autoload first though ---------------------------------------------------------------------------------------------------- [21:22:42] Ryan Stout(@ryanstout):maybe autoloading only on the client makes since ---------------------------------------------------------------------------------------------------- [21:22:52] Elia Schito(@elia):@ryanstout what about something like: ``` if RUBY_ENGINE == 'opal' autoload :Foo, 'foo' else require 'foo' end ``` ---------------------------------------------------------------------------------------------------- [21:23:03] Ryan Stout(@ryanstout):though I guess I was hoping to be able to have it work for users classes also ---------------------------------------------------------------------------------------------------- [21:23:28] Ryan Stout(@ryanstout):but yea, most of the requires in volt are managed by volt ---------------------------------------------------------------------------------------------------- [21:24:06] Ryan Stout(@ryanstout):@elia can you do an autoload of a class that has autoloads? ---------------------------------------------------------------------------------------------------- [21:24:26] Elia Schito(@elia):I guess it wouldn't be a problem ---------------------------------------------------------------------------------------------------- [21:24:45] Ryan Stout(@ryanstout):ok ---------------------------------------------------------------------------------------------------- [21:24:59] Ryan Stout(@ryanstout):googling says autoloading is threadsafe as of 2.0.0 ---------------------------------------------------------------------------------------------------- [21:25:25] Elia Schito(@elia):lol, outdated knowledge is the best :D ---------------------------------------------------------------------------------------------------- [08:07:10] Elia Schito(@elia):> @bwl21 no, this is a recurring issue, only way to solve this is change the third party lib, send them a PR ;) ---------------------------------------------------------------------------------------------------- [08:07:40] Elia Schito(@elia):@gabrielrios maybe we'll have a docs page explaining all the things about that :) ---------------------------------------------------------------------------------------------------- [12:38:19] Mitch VanDuyn(@catmando):@elia What is Adam's gitter handle? ---------------------------------------------------------------------------------------------------- ############################## [2015-09-08] ############################## [00:04:25] Gabriel Rios(@gabrielrios):@RickCarlino I think its pretty complete, but I have only one app using it for chat might not have hit all the corners of firebase as its was not that complex use case ---------------------------------------------------------------------------------------------------- [00:51:45] Jamie Gaskins(@jgaskins):@elia @ryanstout I knew it'd been threadsafe in Rubinius and JRuby for years, but TBH I didn't know it was in MRI yet.

SO the above lambda { |*args| ... } will only look like there is one arg. So just curious how I could somehow hack at the JS level to do do something like this: ```javascript block.bind(#{some_self}) ``` I tried that and it doesn't seem to work btw: ```ruby class Foo def self.do_it(instance, &block) `block.bind(instance)`.call end def initialize(y) @x = y end def baz @x end end foo = Foo.new(12) puts Foo.do_it(foo) { baz } ``` (says `NoMethodError: undefined method `baz' for main` so its not applying the binding... ) ---------------------------------------------------------------------------------------------------- [20:57:53] Elia Schito(@elia):@catmando it's internal api, but there's a .$$self on procs that should work ---------------------------------------------------------------------------------------------------- [20:58:25] Mitch VanDuyn(@catmando):.$$self does what? ---------------------------------------------------------------------------------------------------- [20:59:05] Elia Schito(@elia):holds the self value, the block iirc will fallback on `this` if `$$self` is empty ---------------------------------------------------------------------------------------------------- [21:00:00] Mitch VanDuyn(@catmando):so do something like this `block.$$self = instance` ? ---------------------------------------------------------------------------------------------------- [21:00:07] Elia Schito(@elia):``` ($a = ($b = self).$lambda, $a.$$p = (TMP_1 = function(a){var self = TMP_1.$$s || this; if (a == null) a = nil; return self.$p(a)}, TMP_1.$$s = self, TMP_1), $a).call($b) ``` ---------------------------------------------------------------------------------------------------- [21:00:17] Elia Schito(@elia):I was wrong, it's `$$s` ---------------------------------------------------------------------------------------------------- [21:00:35] Elia Schito(@elia):the above code comes from `opal -Oce '-> a { p a }'` ---------------------------------------------------------------------------------------------------- [21:01:05] Elia Schito(@elia):but be warned that's internal api ;) ---------------------------------------------------------------------------------------------------- [21:02:31] Mitch VanDuyn(@catmando):hey it works !!! thanks @elia ---------------------------------------------------------------------------------------------------- [21:02:45] Elia Schito(@elia)::+1: ---------------------------------------------------------------------------------------------------- [21:03:08] Mitch VanDuyn(@catmando):the things people have to do in javascript due to the lack of any meta programming capability. ---------------------------------------------------------------------------------------------------- [21:04:01] Mitch VanDuyn(@catmando):the dsl in javascript has this sort of optional last parameter call back.

GH automatically setups redirects for both web and git so it should be fine for forks ---------------------------------------------------------------------------------------------------- [08:36:21] Bernhard Weichel(@bwl21):@elia the link to documentation on opalrb.org is broken ---------------------------------------------------------------------------------------------------- [08:45:38] Elia Schito(@elia):it is, that's why I need to perform the change above ---------------------------------------------------------------------------------------------------- ############################## [2015-09-12] ############################## [01:28:53] Francesco 'makevoid' Canessa(@makevoid):Idea: ES6toOpal ---------------------------------------------------------------------------------------------------- [01:28:56] Francesco 'makevoid' Canessa(@makevoid):like html2haml ---------------------------------------------------------------------------------------------------- [01:30:36] Francesco 'makevoid' Canessa(@makevoid):can be called JS2Opal or ES something maybe ---------------------------------------------------------------------------------------------------- [01:33:45] Francesco 'makevoid' Canessa(@makevoid):but I think it a lot of s-expressions will be needed to parse and rewrite that ---------------------------------------------------------------------------------------------------- [01:33:54] Kyle Mallette(@kemallette):Quick question: I'm using opal, opal-jquery, opal-rails, etc. I'm having the hardest time trying to figure out how to `bind` to my form's `ajax:*` events. I didn't find `bind` in opal-jquery, but I've tried using `#on` with no luck. ---------------------------------------------------------------------------------------------------- [01:35:40] Kyle Mallette(@kemallette):my goal is to do the following in wonderful ruby: ``` $($.livesearch.settings.searchFormId).bind('ajax:success', function(evt, xhr, status){ $.livesearch.stop(); });``` ---------------------------------------------------------------------------------------------------- [01:43:31] Kyle Mallette(@kemallette):Oh, @zetachang opal-irb is the shit! Much thanks. Also, many thanks to all the contributors present. Opal has been wonderful so far. Feels like I'm rediscovering ruby again.. ---------------------------------------------------------------------------------------------------- [02:52:43] Kyle Mallette(@kemallette):@kemallette is a dumbass ---------------------------------------------------------------------------------------------------- [02:53:26] Kyle Mallette(@kemallette):This works just fine: :) ``` @form.on "ajax:success", nil do |evt, xhr, status | puts "evt: #{evt}, \n xhr: #{xhr}, \n status: #{status}" end ``` ---------------------------------------------------------------------------------------------------- [03:54:15] Mitch VanDuyn(@catmando):@ ---------------------------------------------------------------------------------------------------- [18:02:09] Jamie Gaskins(@jgaskins):@kemallette I think you've got the wrong Chang. opal-irb was done by @fkchang. :-) ---------------------------------------------------------------------------------------------------- [18:17:02] meh.(@meh):jgaskins, do the specs actually expect negative results? ---------------------------------------------------------------------------------------------------- [18:47:37] Jamie Gaskins(@jgaskins):@meh You mean for the bit_length stuff I'm playing with? ---------------------------------------------------------------------------------------------------- [18:48:32] meh.(@meh):jgaskins, yes ---------------------------------------------------------------------------------------------------- [18:48:49] Jamie Gaskins(@jgaskins):Yeah, there's at least one failing spec for it: https://travis-ci.org/jgaskins/opal/jobs/79781606 ---------------------------------------------------------------------------------------------------- [18:50:17] meh.(@meh):jgaskins, there's `Math.log2` on the Ruby side if you need it ---------------------------------------------------------------------------------------------------- [18:50:43] Jamie Gaskins(@jgaskins):I'm not sure what I'm doing is even worth it. I just saw your commit for it and wanted to see if there's a simpler way. :-) I've done this before in other languages, but I didn't realize the Rubyspecs had so many test cases that I hadn't considered. ---------------------------------------------------------------------------------------------------- [18:50:44] meh.(@meh):and there's a `Math.log2` on the JS side as well with a polyfill ---------------------------------------------------------------------------------------------------- [18:50:57] Jamie Gaskins(@jgaskins):Huh, nice. I didn't know about that. :-) ---------------------------------------------------------------------------------------------------- [18:52:25] Jamie Gaskins(@jgaskins):Also, I can't get all the specs to run in my local environment for some reason, so I decided letting them go to CI would be easier. Then I can squash and do a PR. I didn't realize the gitter channel got notifications of commits to forks. ---------------------------------------------------------------------------------------------------- [18:52:58] meh.(@meh):jgaskins, what's the issue with getting them to run locally? ---------------------------------------------------------------------------------------------------- [18:53:38] meh.(@meh):use PATTERN="spec/rubyspec/core/fixnum/bit_length_spec.rb" ---------------------------------------------------------------------------------------------------- [18:53:40] meh.(@meh):that should work ---------------------------------------------------------------------------------------------------- [18:53:42] Jamie Gaskins(@jgaskins):Most of the time they just get hung up in a certain spot. ---------------------------------------------------------------------------------------------------- [18:53:44] Jamie Gaskins(@jgaskins):Ah, okay ---------------------------------------------------------------------------------------------------- [18:54:55] Jamie Gaskins(@jgaskins):Nice, that works! ---------------------------------------------------------------------------------------------------- [18:55:24] Jamie Gaskins(@jgaskins):But yeah, the full RubySpec suite gets about halfway through and just sits there for a while. I don't know if there's something wrong with my local env. ---------------------------------------------------------------------------------------------------- [18:55:44] meh.(@meh):how are you running it? ---------------------------------------------------------------------------------------------------- [18:56:26] Jamie Gaskins(@jgaskins):`rake SUITE=rubyspec` ---------------------------------------------------------------------------------------------------- [18:56:41] meh.(@meh):it should be `rake mspec_node SUITE=rubyspec` ---------------------------------------------------------------------------------------------------- [18:57:21] Jamie Gaskins(@jgaskins):ahh, okay. I remember at one point I could just run `rake` and it would run all the things, but that changed somewhat recently? ---------------------------------------------------------------------------------------------------- [18:57:36] meh.(@meh):I don't know what it's going to run ---------------------------------------------------------------------------------------------------- [18:57:39] meh.(@meh):but it may be running things that hang :P ---------------------------------------------------------------------------------------------------- [18:57:46] Jamie Gaskins(@jgaskins)::-D ---------------------------------------------------------------------------------------------------- [18:57:50] meh.(@meh):like mspec_phantom ---------------------------------------------------------------------------------------------------- [18:57:52] meh.(@meh):it hangs on my machine ---------------------------------------------------------------------------------------------------- [18:58:04] Jamie Gaskins(@jgaskins):That might be it. ---------------------------------------------------------------------------------------------------- [20:28:47] Jamie Gaskins(@jgaskins):@meh Doesn't look like that simplification is worthwhile. It breaks because floating-point precision. We need to use `Math.floor(Math.log2(n)) + 1` to figure out the number of bits, but for large values of `Math.log2((2 ** i) - 1)`, that gets too close to the next highest integer and the VM treats it as that integer. ```ruby [1] pry(main)> (1..64).map {|i| (1 << i) - 1}.map { |i| p i; [i, i.bit_length, Math.log2(i).floor + 1, Math.log2(i)] } => [[1, 1, 1, 0.0], [3, 2, 2, 1.584962500721156], [7, 3, 3, 2.807354922057604], [15, 4, 4, 3.9068905956085187], [31, 5, 5, 4.954196310386875], [63, 6, 6, 5.977279923499917], ...snip...

It defeats the purpose of simplifying it. ---------------------------------------------------------------------------------------------------- [20:32:14] Jamie Gaskins(@jgaskins):It was a really interesting reason for the tests to fail. I was really struggling to figure out why it worked just fine for the usual range of numbers you see, but got borked when it tried to do it on `fixnum_max` in the spec. ---------------------------------------------------------------------------------------------------- [20:36:29] meh.(@meh):jgaskins, our bitwise operations are 32 bit bound ---------------------------------------------------------------------------------------------------- [20:36:40] meh.(@meh):anything bigger we can ignore as unsupported ---------------------------------------------------------------------------------------------------- ############################## [2015-09-13] ############################## [03:12:32] Jamie Gaskins(@jgaskins):Interesting.

I think the android team does stuff like that. ---------------------------------------------------------------------------------------------------- [23:39:06] Forrest Chang(@fkchang):It could be free, we just need to host the individual talks as standlone videos, like how confreaks host them ---------------------------------------------------------------------------------------------------- [23:39:50] Elia Schito(@elia):@meh totally do it plz!!!! ---------------------------------------------------------------------------------------------------- [23:42:08] Forrest Chang(@fkchang):I believe the feature we need is Google Hangouts On Air, these guys did basically what I want to do, but for librarians http://publiclibrariesonline.org/2014/10/a-free-virtual-conference-for-librarians-its-on/ ---------------------------------------------------------------------------------------------------- [23:42:52] Forrest Chang(@fkchang):@meh should wear a suit like his icon, and the get something that erases his face ---------------------------------------------------------------------------------------------------- [23:43:37] meh.(@meh):@meh owns no suits ---------------------------------------------------------------------------------------------------- [23:44:30] Forrest Chang(@fkchang):rent ---------------------------------------------------------------------------------------------------- [23:44:39] Forrest Chang(@fkchang):or borrow ---------------------------------------------------------------------------------------------------- [23:45:42] Forrest Chang(@fkchang):I think this could really work, we could basically do what the librarians did ---------------------------------------------------------------------------------------------------- [23:48:52] Forrest Chang(@fkchang):FORAIC - future of ruby and it's culture 2015 ---------------------------------------------------------------------------------------------------- [23:49:15] Forrest Chang(@fkchang):anyone in?

It would be great for users and great for the reputation of Opal if there were some support for Opal in IDEA: * Language injection * sourcemaps There is an issue in their tracker: https://youtrack.jetbrains.com/issue/RUBY-13472 It would be great if other Opal users could comment there and express their interest. ---------------------------------------------------------------------------------------------------- [21:04:00] Elia Schito(@elia):@meh ping ---------------------------------------------------------------------------------------------------- [21:04:07] meh.(@meh):@elia pong ---------------------------------------------------------------------------------------------------- [21:04:13] Elia Schito(@elia):was forcing myself on writing some api docs ---------------------------------------------------------------------------------------------------- [21:04:34] Elia Schito(@elia):and kinda liking the (narcissistic) tomdoc ---------------------------------------------------------------------------------------------------- [21:04:58] Elia Schito(@elia):but wanted to check with you before committing to it ---------------------------------------------------------------------------------------------------- [21:05:33] meh.(@meh):what's wrong with yard? ---------------------------------------------------------------------------------------------------- [21:06:03] Elia Schito(@elia):dunno, kinda remember it was a bit more formal ---------------------------------------------------------------------------------------------------- [21:06:16] Elia Schito(@elia):but never learned well any doc format ---------------------------------------------------------------------------------------------------- [21:13:45] Elia Schito(@elia):@meh yes, tomdoc is a bit more human readable while yardoc is more machine parsable ---------------------------------------------------------------------------------------------------- [21:15:12] Elia Schito(@elia):anyways was kinda unaware there was some commitment to yard in the project (~10 files) ---------------------------------------------------------------------------------------------------- [21:15:34] Elia Schito(@elia):and recently switched to sdoc ---------------------------------------------------------------------------------------------------- [21:16:21] Elia Schito(@elia):eg. http://opalrb.org/docs/api/v0.8.0/lib/index.html ---------------------------------------------------------------------------------------------------- [21:17:52] Elia Schito(@elia):I can migrate existing documentation (as time permits) if you agree ---------------------------------------------------------------------------------------------------- [21:18:29] meh.(@meh):meh ---------------------------------------------------------------------------------------------------- [22:01:02] Ryan Stout(@ryanstout):@fkchang did you submit a rubyconf talk this year? ---------------------------------------------------------------------------------------------------- [22:01:28] Ryan Stout(@ryanstout):(or anyone else) ---------------------------------------------------------------------------------------------------- [22:18:32] Forrest Chang(@fkchang): @ryanstout I submitted 4, all 4 got some kind of discussion, so I'm hopeful one gets accepted ---------------------------------------------------------------------------------------------------- [22:19:03] Ryan Stout(@ryanstout):@fkchang nice, I did 3, all rejected :-( ---------------------------------------------------------------------------------------------------- [22:19:16] Ryan Stout(@ryanstout):2 had just positive feedback :-) ---------------------------------------------------------------------------------------------------- [22:20:08] Forrest Chang(@fkchang):oh, I see that all 4 got rejected now that I checked my email ---------------------------------------------------------------------------------------------------- [22:20:17] Ryan Stout(@ryanstout):man ---------------------------------------------------------------------------------------------------- [22:20:26] Ryan Stout(@ryanstout):what does it take to get a talk accepted ---------------------------------------------------------------------------------------------------- [22:20:35] Ryan Stout(@ryanstout):@fkchang what were yours on? ---------------------------------------------------------------------------------------------------- [22:21:57] Forrest Chang(@fkchang):I have no idea, I always think of my talk as along the lines of saving Ruby and it's culture.

Try to get a lightning talk in, but it's hard to get in coz those are so popular ---------------------------------------------------------------------------------------------------- [22:27:16] Forrest Chang(@fkchang):who knows, maybe we'll get a last minute callback like you did last year ---------------------------------------------------------------------------------------------------- [22:56:46] Ryan Stout(@ryanstout):yea, I think last year that was partly because I complained ---------------------------------------------------------------------------------------------------- [22:57:13] Ryan Stout(@ryanstout):yea, I'm going to go either way I think ---------------------------------------------------------------------------------------------------- [23:10:59] meh.(@meh):@fkchang wonder if they rejected the Opal related ones because of #941 :^) ---------------------------------------------------------------------------------------------------- [23:28:22] Forrest Chang(@fkchang):@ryanstout how did you go about complaining? ---------------------------------------------------------------------------------------------------- [23:28:32] Forrest Chang(@fkchang):@meh it's always possible ---------------------------------------------------------------------------------------------------- [23:28:46] Forrest Chang(@fkchang):@/all is it time to do an opalconf?

We can do like the librarians and put up a page, take registrations, and get "really nitty gritty technical" ---------------------------------------------------------------------------------------------------- [00:02:03] Ryan Stout(@ryanstout):@fkchang my original thought was maybe 5 talks over a few hours.

From what I can of the "virtual confs" (I think they are calling them "stay at home confs"), is they are like a few hours over a few consecutive days, so people can do them after work ---------------------------------------------------------------------------------------------------- [00:03:29] meh.(@meh):then I can keep the laughing man spinnan thing shown ---------------------------------------------------------------------------------------------------- [00:04:03] Forrest Chang(@fkchang):@meh can have the computer voice and Stephen Hawkings video... ---------------------------------------------------------------------------------------------------- [00:04:27] Forrest Chang(@fkchang):so I'd like for FORAIC to be like the stay at home confs, we'd have a "week of opal" ---------------------------------------------------------------------------------------------------- [00:06:32] Forrest Chang(@fkchang):who's got some design chops, or access to such ---------------------------------------------------------------------------------------------------- [00:07:40] George Plymale II(@ylluminarious)::+1: ---------------------------------------------------------------------------------------------------- [00:09:49] Forrest Chang(@fkchang):I have ideas for the foraic.org site, I should throw together a rough copy, "If you build it, they will come" -- hopefully ---------------------------------------------------------------------------------------------------- [00:12:54] Ilya Bylich(@iliabylich):@fkchang Amazing idea, don't understand why it wasn't proposed before ---------------------------------------------------------------------------------------------------- [00:13:33] Ilya Bylich(@iliabylich)::+1: for @meh 's confession ---------------------------------------------------------------------------------------------------- [00:14:48] Ilya Bylich(@iliabylich):If it's going to be a live conference, which timezone it will be? ---------------------------------------------------------------------------------------------------- [00:15:08] Forrest Chang(@fkchang):Ok, they're called remote confs, not stay at home cofn Structurally, this is the model, imo https://rubyremoteconf.com ---------------------------------------------------------------------------------------------------- [00:17:30] Forrest Chang(@fkchang):@iliabylich ah yes, time zone...I see rubyremoteconf was during the day EST, I guess it depends on whats best for the majority of the speakers, or possibly the attendees?

I kind of think it technically belongs under ruby ---------------------------------------------------------------------------------------------------- [22:00:41] Elia Schito(@elia):@fkchang yeah, personally I don't care much where we end up in the list but rather if we have an "awesome"™ page :) ---------------------------------------------------------------------------------------------------- ############################## [2015-09-19] ############################## [11:54:27] Bernhard Weichel(@bwl21):JSON.load does not yield a hash. http://opalrb.org/try/?code:require%20%27json%27%0A%0Axx%20%3D%20JSON.load(%25q%7B%7B%22a%22%3A%22this-is-a%22%7D%7D)%0Aputs%20xx JSON.parse works. Is there an incompatiblity? ---------------------------------------------------------------------------------------------------- [14:46:15] Elia Schito(@elia):@bwl21 what's the difference between the two? ---------------------------------------------------------------------------------------------------- [16:33:18] Bernhard Weichel(@bwl21):load yields "true" while parse yields the intended hash ---------------------------------------------------------------------------------------------------- [16:34:18] Bernhard Weichel(@bwl21):Ruby doc says that load is more basic while parse is more error prone ---------------------------------------------------------------------------------------------------- ############################## [2015-09-20] ############################## [13:19:40] Jose Añasco(@merongivian): ---------------------------------------------------------------------------------------------------- [14:48:50] Jamie Gaskins(@jgaskins):@merongivian it's not in there yet. I noticed the same the other day when I wanted to add my own controls to a video. I was thinking of submitting a PR for it, but I'm at a hackathon this weekend so I haven't had time. ---------------------------------------------------------------------------------------------------- [14:51:57] Jose Añasco(@merongivian):@jgaskins are you sending it to opal directly or to some other gem (like the opal-browser)? ---------------------------------------------------------------------------------------------------- [14:52:32] Jamie Gaskins(@jgaskins):@elia Agreed. Or, maybe, since it's functionality is quite similar to `JSON.parse`, maybe have it run parse and warn "hey, we think maybe you actually want parse, so we ran that instead." ---------------------------------------------------------------------------------------------------- [14:52:50] Jamie Gaskins(@jgaskins):@merongivian Opal ---------------------------------------------------------------------------------------------------- [14:53:01] Jamie Gaskins(@jgaskins):er, opal-browser ---------------------------------------------------------------------------------------------------- [14:53:30] Jamie Gaskins(@jgaskins):running gitter on an iPad is a gross ux, in case anyone is wondering. ---------------------------------------------------------------------------------------------------- [14:55:14] Jose Añasco(@merongivian):@jgaskins cool, let me know when you push it, i want to create a wrapper for creating keyboard-like sounds, probably im going to reuse band.js library or create my own.. ---------------------------------------------------------------------------------------------------- [15:03:54] Jose Añasco(@merongivian):@jgaskins or i can give it a try if you're busy, let me now either way :smile: ---------------------------------------------------------------------------------------------------- [15:37:30] Bernhard Weichel(@bwl21):@jgaskins @elia In this case it would be good to fall back to parse and raise a warning. This leads me to the propose to have a kind of mode control to configure the messages/exceptions raised by opal at runtime. This allows to have more checks on development time but not bother the regular user at runtime with messages he cannot fix. ---------------------------------------------------------------------------------------------------- [03:55:34] Jamie Gaskins(@jgaskins):@elia @bwl21 I think `JSON.load` can load JSON as arbitrary types instead of just hashes, similar to `YAML.load`. I don't remember the details, but basically the idea is that you almost always want `parse` instead of `load` if you want a hash result. ---------------------------------------------------------------------------------------------------- [03:56:08] Jamie Gaskins(@jgaskins):I really only remember a few things about it from when the `YAML.load` vulnerability was discovered in Rails. ---------------------------------------------------------------------------------------------------- [10:51:06] David Boardman(@djboardman):I'm getting an rspec error trying to run Volt specs against opal 0.9.0.dev (this working for 0.9.0.dev until I updated this morning but I hadn't updated for a while). opal-rspec is on 0.4.3 `NoMethodError: undefined method 'delegate_to_metadata' for ` ` http://localhost:9999/assets/opal/rspec/sprockets_runner.js:4165` `...` ---------------------------------------------------------------------------------------------------- [12:58:58] Elia Schito(@elia):@jgaskins maybe then we should raise a "not implemented error" on JSON.load or remove the method entirely ---------------------------------------------------------------------------------------------------- [12:59:35] Elia Schito(@elia):@djboardman is it possible that you also have upgraded phantomjs? ---------------------------------------------------------------------------------------------------- [13:01:33] Elia Schito(@elia):otherwise would be great if you can git bisect to the exact commit that broke the spec 😊 ---------------------------------------------------------------------------------------------------- [13:17:15] Jose Añasco(@merongivian):Hey guys, have a question, is there a wrapper for the web audio api ?, i saw that you guys created a wrapper for some html5 features (opal-browser) but didn't find web audio api in the readme ---------------------------------------------------------------------------------------------------- ############################## [2015-09-21] ############################## [22:55:42] meh.(@meh):elia, where? ---------------------------------------------------------------------------------------------------- [22:55:59] Elia Schito(@elia):https://github.com/opal/opal/pulls ---------------------------------------------------------------------------------------------------- [22:56:01] Elia Schito(@elia)::) ---------------------------------------------------------------------------------------------------- [22:56:03] meh.(@meh):ah ok ---------------------------------------------------------------------------------------------------- [06:19:18] David Boardman(@djboardman):@elia I thought you might ask me that - so far somewhere between 23 Jul and 28 Aug but I'll try and find it. Phantomjs still on 1.9.8... ---------------------------------------------------------------------------------------------------- [15:16:00] Ilya Bylich(@iliabylich):Do you plan to release opal as a standalone version of ruby so it would be possible to install it using rvm and test libraries compatibility on travis? ---------------------------------------------------------------------------------------------------- [15:16:33] Ilya Bylich(@iliabylich):Because currently we don't know which pure ruby libraries have opal support ---------------------------------------------------------------------------------------------------- [15:17:40] Ilya Bylich(@iliabylich):something like `rvm install opal-0.9.0; rvm use opal-0.9.0; rspec` which runs specs using opal through nodejs (?) ---------------------------------------------------------------------------------------------------- [15:18:07] Elia Schito(@elia):@iliabylich I started that in the past but to do that would need to reimplement rubygems in nodejs or having it live in both worlds ---------------------------------------------------------------------------------------------------- [15:19:20] Ilya Bylich(@iliabylich):@elia Is the problem only with load paths? ---------------------------------------------------------------------------------------------------- [15:19:43] Elia Schito(@elia):which is not impossible but requires time. An alternative could be to have clear instructions on how to test libs in opal too and let ppl add them to their .travis.yml ---------------------------------------------------------------------------------------------------- [15:20:31] Elia Schito(@elia):if the rvm opal is based on nodejs then it must support ruby gems to downlaod the deps of the gem under test ---------------------------------------------------------------------------------------------------- [15:21:35] Elia Schito(@elia):if we keep using MRI we need a way to expose rubygems for the same reason but keep the `ruby` executable pointing to `opal` ---------------------------------------------------------------------------------------------------- [15:22:03] Ilya Bylich(@iliabylich):But opal itself requires some native ruby for its parser, right? ---------------------------------------------------------------------------------------------------- [15:22:27] Ilya Bylich(@iliabylich):Then `ruby` can actually invoke a real ruby (which can download all deps) + opal parser ---------------------------------------------------------------------------------------------------- [15:23:35] Elia Schito(@elia):no, the nodejs version would be entirely JS based (as `opal-parser` compiles and works under JS too) ---------------------------------------------------------------------------------------------------- [15:24:45] Elia Schito(@elia):@iliabylich in fact `rvm list known` still lists opal, which is done with that technique but uses an ancient version ---------------------------------------------------------------------------------------------------- [15:29:01] Ilya Bylich(@iliabylich):Can't install it :D ---------------------------------------------------------------------------------------------------- [15:32:44] Elia Schito(@elia):yeah, it's old ---------------------------------------------------------------------------------------------------- [15:33:22] Elia Schito(@elia):but hey, if you want to give a try at alternative solutions I'll give all the support :) ---------------------------------------------------------------------------------------------------- [15:39:33] Ilya Bylich(@iliabylich):I've realized that for making a standalone `opal-ruby` stuff like bundler and rake should be implemented in the first turn, right? Then, I suppose, we should just wait :D ---------------------------------------------------------------------------------------------------- [15:40:52] Elia Schito(@elia):yes, the current `opal` CLI is very similar to the `ruby` (mri) CLI in terms of options, but as you say there's more to that ---------------------------------------------------------------------------------------------------- [17:31:07] Ilya Bylich(@iliabylich):@elia phantomjs is crashing on CI - https://travis-ci.org/opal/opal/jobs/81430315. Did you have any segfaults like this locally? ---------------------------------------------------------------------------------------------------- [17:40:30] Elia Schito(@elia):Not last time i checked, thanks for the heads up, I'll check later and if I get the time I'll update to v2 as well ---------------------------------------------------------------------------------------------------- [18:26:21] Torsten Rüger(@dancinglightning):@elia a node based opal-ruby sounds like a good idea (one i would be willing to help a little with), but i must be missing something in the discussion. Why would one not just compile bundler/rake/gems with opal and use those. Ok, some path mapping, but otherwise? ---------------------------------------------------------------------------------------------------- [18:29:55] Ilya Bylich(@iliabylich):@dancinglightning For example, check out Opal's `File` implementation - https://github.com/opal/opal/blob/master/opal/corelib/file.rb ---------------------------------------------------------------------------------------------------- [18:30:23] Ilya Bylich(@iliabylich):A lot of similar stuff should be re-implemented through node ---------------------------------------------------------------------------------------------------- [18:39:14] Torsten Rüger(@dancinglightning):@iliabylich kind of short, but maybe help me: what am i seeing there ? ---------------------------------------------------------------------------------------------------- [18:41:51] Ilya Bylich(@iliabylich):No interaction with file system. Bundler and rake both need it, so they can't be compiled with Opal, core functionality of standalone-ruby is missing ---------------------------------------------------------------------------------------------------- [18:45:12] Torsten Rüger(@dancinglightning):@iliabylich ok, so i misread. You’re basically talking about having to flesh out the missing pieces of the core (and possibly std) lib. Not as i misunderstood doing anything per se node (non-ruby) specific. ---------------------------------------------------------------------------------------------------- [18:49:27] Ilya Bylich(@iliabylich):As I know, this parts will never be implemented. Opal is for browser, you don't need files/threads/processes/ruby http/signals and other things on the client. For a standalone opal (as a package) all of these parts have to be made through some wrapper that runs it (node or phantomjs) ---------------------------------------------------------------------------------------------------- [18:54:04] Torsten Rüger(@dancinglightning):ok, i missed that part. i thought opal was ruby on js, not just ruby on the browser. No problem. But yes, then that would leave somebody else to fill that part. And then it would be a much bigger task than i imagined :-( ---------------------------------------------------------------------------------------------------- [21:01:56] Elia Schito(@elia):@iliabylich @dancinglightning actually the stdlib has some of those parts implemented from when I did a spike with nw.js / atom-shell, just `require "nodejs"` ---------------------------------------------------------------------------------------------------- [21:02:27] Elia Schito(@elia):eg. https://github.com/opal/opal/blob/master/stdlib/nodejs/file.rb ---------------------------------------------------------------------------------------------------- [21:03:15] Elia Schito(@elia):the main reason for which i made the RVM stuff back then was it was really cool installing opal that way ---------------------------------------------------------------------------------------------------- [21:03:46] Elia Schito(@elia):the other reason was to make it easy for people / show off / get some hype etc. ---------------------------------------------------------------------------------------------------- [21:04:32] Elia Schito(@elia):But having not practical usage and not enough time made me stop ---------------------------------------------------------------------------------------------------- [21:07:14] Torsten Rüger(@dancinglightning): nice bag of goodies , that nodejs folder. Did you try compiling gem or bundler, any clue to how much is missing ? Not that i have one of those practical uses things. ---------------------------------------------------------------------------------------------------- [21:33:16] Elia Schito(@elia):@dancinglightning nope, but I'm sure they'd need Net::HTTP and friends which for now are missing ---------------------------------------------------------------------------------------------------- [21:35:39] Elia Schito(@elia):@iliabylich about the crash I checked and yes, now I remember, sometimes it happens ---------------------------------------------------------------------------------------------------- [21:35:54] Elia Schito(@elia):I restarted the job, that's usually enough ---------------------------------------------------------------------------------------------------- [21:45:18] Jose Añasco(@merongivian):Hey @/all , im making a pr for opal-browser but i can't run the test suite , i did `bundle exec rake` but it says that rake isn't part of the bundle... ---------------------------------------------------------------------------------------------------- [21:45:45] Elia Schito(@elia):@meh ^ ---------------------------------------------------------------------------------------------------- [21:46:22] meh.(@meh):@merongivian opal-browser tests are borked and need a fixing, don't worry about it, just make the pull request ---------------------------------------------------------------------------------------------------- [21:46:50] Jose Añasco(@merongivian):@meh ah ok then , thanks ---------------------------------------------------------------------------------------------------- [21:47:22] meh.(@meh):@elia I recall you trying to fix them? or am I imagining things? ---------------------------------------------------------------------------------------------------- [21:47:49] Elia Schito(@elia):@meh I recall that too, but kinda in another life ---------------------------------------------------------------------------------------------------- [21:48:01] meh.(@meh):someone gotta do it sooner or later :P ---------------------------------------------------------------------------------------------------- [21:48:14] Elia Schito(@elia):yep, checking my local checkout ---------------------------------------------------------------------------------------------------- [21:52:43] Elia Schito(@elia):@meh what about a releasing guide, like stuff to check for each release?

I saw a game based on opal-phaser a while back — something with spiders, I think? It played pretty well and the code for it looked really nice. This was before I knew how well Opal performed, so I remember being pretty amazed with the performance at the time. ---------------------------------------------------------------------------------------------------- [01:48:30] Jamie Gaskins(@jgaskins):@meh I just noticed that the `Promise` class is implemented as a linked list to pass things down the chain. Is there any reason we shouldn't let promises point to more than one other promise? For example: ```ruby request = Browser::HTTP.get('/foo') request.then { do_a_thing } request.then { do_another_thing } ``` ---------------------------------------------------------------------------------------------------- [01:49:43] Jamie Gaskins(@jgaskins):It was a little confusing when I couldn't because JS promises allow that, so I don't know if that was intentional. ---------------------------------------------------------------------------------------------------- [02:40:06] George Plymale II(@ylluminarious):@jgaskins thanks! that project sounds really interesting; don't think i've seen it before. do you have a link? ---------------------------------------------------------------------------------------------------- [03:38:05] Jamie Gaskins(@jgaskins):@ylluminarious I don't seem to be able to find it. I think it might've been a port of a Phaser-based game to Opal-Phaser.

My Rakefile uses Opal::Builder.build, which works great. However, I would like to use the opal cdn for all the framework code, so I try switching to Opal.compile in my Rakefile. How do I get Ruby core and stdlib modules my app needs included in the generated javascript? Or is there some option to Opal::Builder.build I could use to exclude opal and its libraries from being included in the generated javascript? ---------------------------------------------------------------------------------------------------- [10:52:27] Elia Schito(@elia):@lhz Opal.compile is low level, so you have to do it manually, but that would mean replicating what Opal::Builder already does… ---------------------------------------------------------------------------------------------------- [10:52:48] Elia Schito(@elia):@lhz any particular reason for wanting to switch to the CDN? ---------------------------------------------------------------------------------------------------- [10:54:01] Lars Haugseth(@lhz):Not other than I plan to make many small canvas apps, and it seems wasteful to include 800KB+ of the same javascript code in each of them. ---------------------------------------------------------------------------------------------------- [10:54:23] Elia Schito(@elia):I see :) ---------------------------------------------------------------------------------------------------- [10:55:01] Elia Schito(@elia):so you just want to build without the core/std stuff right? ---------------------------------------------------------------------------------------------------- [10:55:53] Lars Haugseth(@lhz):Yeah. ---------------------------------------------------------------------------------------------------- [10:56:40] Elia Schito(@elia):This should be enough: ``` b = Opal::Builder.new b.build_str 'puts 4', '(eval)' File.write 'four.js', b.to_s ``` ---------------------------------------------------------------------------------------------------- [10:56:54] Elia Schito(@elia):unless - of course - I'm missing something :) ---------------------------------------------------------------------------------------------------- [10:59:01] Lars Haugseth(@lhz):This is what I have that works: ---------------------------------------------------------------------------------------------------- [10:59:11] Lars Haugseth(@lhz): Opal.append_path "app" File.binwrite "test.js", Opal::Builder.build("test").to_s ---------------------------------------------------------------------------------------------------- [11:00:07] Lars Haugseth(@lhz):And my app code is in app/test.rb ---------------------------------------------------------------------------------------------------- [11:00:54] Elia Schito(@elia):so, builder will search for `require` inside your code and include required files in the bundle ---------------------------------------------------------------------------------------------------- [11:02:07] Elia Schito(@elia):to avoid that you have to pass an Array as the `prerequired` option at builder initialization: eg. `Opal::Builder.new prerequired: ['set', 'ostruct']` ---------------------------------------------------------------------------------------------------- [11:02:34] Elia Schito(@elia):that should make it skip including Set and OpenStruct ---------------------------------------------------------------------------------------------------- [11:07:12] Lars Haugseth(@lhz):Ok, tried now using Opal::Builder.new(prerequired: ['opal', 'browser', 'browser/canvas', 'browser/interval']) ---------------------------------------------------------------------------------------------------- [11:07:37] Lars Haugseth(@lhz):Then I get "Uncaught NoMethodError: undefined method `every' for #" ---------------------------------------------------------------------------------------------------- [11:07:48] Lars Haugseth(@lhz):So progress at least :) ---------------------------------------------------------------------------------------------------- [11:07:59] Elia Schito(@elia):you get that in the browser or while compiling? :P ---------------------------------------------------------------------------------------------------- [11:08:09] Lars Haugseth(@lhz):In the browser console ---------------------------------------------------------------------------------------------------- [11:08:50] Elia Schito(@elia):you may want to check the versions you're getting from the CDN vs local ---------------------------------------------------------------------------------------------------- [11:10:02] Lars Haugseth(@lhz):using opal-browser-0.2.0, and that is the one I have locally as well. Browser::Interval should add #every to Kernel. ---------------------------------------------------------------------------------------------------- [11:10:36] Lars Haugseth(@lhz):and to Window as well. ---------------------------------------------------------------------------------------------------- [11:10:39] Elia Schito(@elia):also libraries in the CDN must be compiled against the same version of opal ---------------------------------------------------------------------------------------------------- [11:11:25] Elia Schito(@elia):that's why I asked about the use case, as using the CDN has some gotchas ---------------------------------------------------------------------------------------------------- [11:12:04] Elia Schito(@elia):but you can compile browser locally and source it from your server instead of the CDN ---------------------------------------------------------------------------------------------------- [11:17:00] Lars Haugseth(@lhz):Ok, got it to work by using only 'opal' and 'browser' as prerequired. ---------------------------------------------------------------------------------------------------- [11:17:28] Elia Schito(@elia):great! ---------------------------------------------------------------------------------------------------- [11:18:12] Lars Haugseth(@lhz):Which means browser/canvas and browser/interval is compiled in, but I can live with that. 60KB is still much better than 800 KB. :) Thanks a lot for the hints! ---------------------------------------------------------------------------------------------------- [11:18:55] Elia Schito(@elia)::+1: ---------------------------------------------------------------------------------------------------- [13:40:09] Lars Haugseth(@lhz):Strange, the `every(1.0 / 60) { update }`block seems to run every 16.67 ms in Chrome on Ubuntu, but it runs only half as often in Chrome on Windows 7.

Maybe a different directory would solve it, if not then if I had 2 opal files of the same names, would they conflict? say 'subdir1/klass.rb' and 'subdir2/klass.rb' ? ---------------------------------------------------------------------------------------------------- [23:00:20] Elia Schito(@elia):no the different dir definitely solves it, 0.8 relies on sprockets for the file lookup, that means you would have the same problem if the files were `foo.js.coffee` and `foo.eco` ---------------------------------------------------------------------------------------------------- [23:00:45] Forrest Chang(@fkchang):so if I were to put views in a subdir, that should work, I'll try it ---------------------------------------------------------------------------------------------------- [23:00:53] Forrest Chang(@fkchang):but good to know about the clash ---------------------------------------------------------------------------------------------------- [23:00:54] Elia Schito(@elia):I think builder is still able to differentiate between them tho ---------------------------------------------------------------------------------------------------- [23:10:32] Forrest Chang(@fkchang):@elia hmmm, what worked on 0.7 doesn't work, I put it under app/assets/javascripts/views the require seems to work (both ```require 'test_class.haml'``` and ```require 'views/test_class.haml``` but I can figure out how to reference it Tempate['test_class'] Template['test_class.haml'] and Template['views/test_class.haml'] all fail ---------------------------------------------------------------------------------------------------- [23:28:15] Forrest Chang(@fkchang):ok, it's Template['views/test_class'] ---------------------------------------------------------------------------------------------------- [23:30:05] Forrest Chang(@fkchang):updated the github so it works, if anyone needs a reference ---------------------------------------------------------------------------------------------------- [00:46:40] Forrest Chang(@fkchang):@elia I don't get that error anymore but I get this ```couldn't find file 'boolean_editor.html.haml' with type 'application/javascript' ``` ---------------------------------------------------------------------------------------------------- [00:47:20] Forrest Chang(@fkchang):do I need to require them differently? I have been doing ```require 'boolean_editor.html.haml'``` ---------------------------------------------------------------------------------------------------- [01:58:01] Jamie Gaskins(@jgaskins):@fkchang What happens when you just do `require 'boolean_editor'`? ---------------------------------------------------------------------------------------------------- [17:07:04] Forrest Chang(@fkchang):@jgaskins I'd have to rename stuff to try that I have ruby code and templates with the same root name (my convention for keeping them correlated). I might start a fresh rails project to explore what the correct template require scheme is. I ended up doing the full require 'boolean_editor.html.haml' in a previous project to disambiguate tempate vs code because of said naming scheme, which worked fine on 0.6 and 0.7 ---------------------------------------------------------------------------------------------------- [17:07:28] Mark Howard(@iheartkode):Hello Everyone ---------------------------------------------------------------------------------------------------- [17:07:40] Forrest Chang(@fkchang):@elia have any template require tips? ---------------------------------------------------------------------------------------------------- [17:07:46] Forrest Chang(@fkchang):hi @iheartkode ---------------------------------------------------------------------------------------------------- [17:07:51] Elia Schito(@elia):Hi! ---------------------------------------------------------------------------------------------------- [17:08:14] Mark Howard(@iheartkode):Ruby to JS wow I hate Js but love Ruby ---------------------------------------------------------------------------------------------------- [17:08:52] Elia Schito(@elia):@fkchang I require them without extension ---------------------------------------------------------------------------------------------------- [17:09:10] Elia Schito(@elia):are you using Opal Builder or sprockets ? ---------------------------------------------------------------------------------------------------- [17:11:26] Mark Howard(@iheartkode):So what are the common uses for Opal? ---------------------------------------------------------------------------------------------------- [17:47:56] George Plymale II(@ylluminarious):@iheartkode pretty much any common use of javascript ;) ---------------------------------------------------------------------------------------------------- [17:47:57] Forrest Chang(@fkchang):@elia it's opal-rails, so sprockets ---------------------------------------------------------------------------------------------------- [17:49:10] Forrest Chang(@fkchang):@elia is there a way to tell opal/opal-rails the difference between name.rb and name.html.haml, as both would be require 'name' ---------------------------------------------------------------------------------------------------- [17:49:53] Forrest Chang(@fkchang):@iheartkode I try to use it for any non trivial use of javascript, sometimes a few lines here and there in a vanilla rails app is all I need, but once there's complexity involved, I switch to opal ---------------------------------------------------------------------------------------------------- [17:50:13] Mark Howard(@iheartkode):Sweet ---------------------------------------------------------------------------------------------------- [18:06:36] Elia Schito(@elia):@fkchang :bulb: drop the ".html" ---------------------------------------------------------------------------------------------------- [18:30:11] Jamie Gaskins(@jgaskins):@elia Good point. It's not being compiled to HTML. It's being compiled to JS. Could Sprockets be having trouble with that discrepancy? ---------------------------------------------------------------------------------------------------- [18:58:47] Forrest Chang(@fkchang):@elia that's an improvement, compiler is happ, now I seem to have an issue with some classes that are defined and required, but opal doesn't know about them.

For those who are unfamiliar with UMD, it's just like Ruby's `require`, but instead of returning `true` / `false` based on whether or not that particular call just loaded it, it can return objects or functions evaluated in that file. And successive requires return the same object instance. This way, instead of requiring files for their side effects, we could require them for their return value. Basically, I don't want to pollute the top-level namespace by assigning object instances to constants, but I also don't want to clutter up my main app file by dumping all of these objects into the one file. ---------------------------------------------------------------------------------------------------- [03:25:30] Jamie Gaskins(@jgaskins):If people are interested, I'll file an issue. It's just one thing I thought the JS community got really right that Ruby got really wrong. :-) ---------------------------------------------------------------------------------------------------- [15:27:00] ll14m4n(@ll14m4n):Hello! I'm trying to use Middleman for static Opal app. How can I enable source maps? Don't even know where to start. ---------------------------------------------------------------------------------------------------- [19:52:58] Adam Jahn(@ajjahn):@elia If you haven't seen https://github.com/opal/opal-activesupport/pull/7 yet, let me know if you need anything else from me to get it merged. Also, would love to see a release too. Building another project against it. ---------------------------------------------------------------------------------------------------- [20:18:12] Elia Schito(@elia):@ajjahn merged thanks! I didn't see it, also cutting a new release right now ---------------------------------------------------------------------------------------------------- [20:20:00] Elia Schito(@elia):@ajjahn one thing that would be cool is to somehow keep a list of implemented stuff, just to make it easier to see if a particular AS thing is there already ---------------------------------------------------------------------------------------------------- [20:20:35] Elia Schito(@elia):maybe the readme could work, or a changelog ---------------------------------------------------------------------------------------------------- [20:24:06] Adam Jahn(@ajjahn):Thanks! Yeah, I was wondering the same thing. I would like to keep implementing things, but it will get tricky keeping track of partially implemented things even with a changeling or readme. ---------------------------------------------------------------------------------------------------- [20:28:08] Elia Schito(@elia):@ajjahn maybe it can help to have a reverse list, like of stuff that are still missing, and each PR will remove relevant lines from it ---------------------------------------------------------------------------------------------------- [20:28:46] Adam Jahn(@ajjahn):I wonder if it would be worth/possible to write a little wrapper over opal-rspec that would run test unit tests without the need to manually convert them. Then we could build against the actual AS tests to see what's missing. Just thinking out loud... ---------------------------------------------------------------------------------------------------- [20:29:40] Adam Jahn(@ajjahn):But you're right, at the very least a list is a good idea to get started. ---------------------------------------------------------------------------------------------------- [20:44:32] Elia Schito(@elia):@ajjahn I used rspec in the first place just for familiarity, I have no problem with switching to unit or minitest, or even to keep them both while we transition ---------------------------------------------------------------------------------------------------- [20:44:54] Elia Schito(@elia):opal-minitest should work to run them ---------------------------------------------------------------------------------------------------- [20:45:59] Adam Jahn(@ajjahn):@elia Oh jeez, I didn't even know opal-minitest existed. Yes I will explore a bit. ---------------------------------------------------------------------------------------------------- [20:47:18] Adam Jahn(@ajjahn):I typically use rspec, but in this case it makes sense to be able to pluck tests from AS and have them run. ---------------------------------------------------------------------------------------------------- [20:57:51] Elia Schito(@elia)::+1: ---------------------------------------------------------------------------------------------------- [20:59:23] Adam Jahn(@ajjahn):@elia Did you release then? ---------------------------------------------------------------------------------------------------- [21:01:48] Elia Schito(@elia):ouch ---------------------------------------------------------------------------------------------------- [21:01:56] Elia Schito(@elia):got distracted :P ---------------------------------------------------------------------------------------------------- [21:04:15] Elia Schito(@elia):@ajjahn https://twitter.com/rubygems/status/652227872699101184 ---------------------------------------------------------------------------------------------------- [21:05:29] Adam Jahn(@ajjahn):Rad!

In contrast, most apps using jQuery and Backbone, for example, interleave DOM reads and writes, which leads to a _lot_ of page reflows during render, which wastes time — and battery life, which seems to be a hot topic these days. Beyond that, you're looking at a difference of a handful of milliseconds, which only the most aggressive performance hounds will notice in most apps. :-) ---------------------------------------------------------------------------------------------------- [16:56:42] Martin Becker(@Thermatix):true enough, but for me it's not just speed, that was just icing on the cake ---------------------------------------------------------------------------------------------------- [16:57:20] Martin Becker(@Thermatix):The internet is supposed to be stateless and most frameworks go against that contract ---------------------------------------------------------------------------------------------------- [16:57:25] Martin Becker(@Thermatix):react doesn't ---------------------------------------------------------------------------------------------------- [16:57:36] Martin Becker(@Thermatix):everything flows in one direction like the internet is supposed to ---------------------------------------------------------------------------------------------------- [16:57:54] Martin Becker(@Thermatix):and once execution is finished, it's done, no state ---------------------------------------------------------------------------------------------------- [17:09:24] Brady Wied(@wied03):Not that my opinion matters a ton but I use react and I like it but I do think React (and the software world in general) is a little bit over the top with immutability these days. State is kind of a fact of life (I've never been able to have my chain of React components be state free). My worry is that the immutability movement is a reaction to OO done the wrong way. OO done the wrong way was Javabeans, etc. where public setters exposed the state of objects to the world. The right fix for that was to do what OO said from the beginning, which is encapsulate, control and ensure a valid state. I'm not sure if eliminating state was really necessary to fix that. I guess I'm a fan of partial immutability then. :) ---------------------------------------------------------------------------------------------------- [18:47:59] Martin Becker(@Thermatix):It's not immutability I have an issue with, just the internet is supposed to be stateless, the problem I have is that most frameworks have states that can change and then be written to backwards AND forwards. You can't do that in react, it has to go one way, something happens (button gets clicked on) which triggers a cascade of changes and then it stops until the next event, which is closer to how the web is because it's a one direction flow. It's because of that I feel it fits web development better then angular or ember ---------------------------------------------------------------------------------------------------- [19:39:36] Jamie Gaskins(@jgaskins):@wied03 Agreed. The craze over immutability is probably just the pendulum swinging the other direction. Immutability is great and solves a lot of problems, but it doesn't solve all of them. I really like Redux and its emphasis on immutability (so much that I based [`grand_central`](https://github.com/clearwater-rb/grand_central) on it) because it works really well for that purpose. UI elements being stateless is nice, but as you mentioned, it's not pragmatic to do it everywhere. You'd have to put that state in your store or in the URL. ---------------------------------------------------------------------------------------------------- [19:40:09] Jamie Gaskins(@jgaskins):@Thermatix I'm not sure I follow what you're saying. HTTP is stateless, but what else about the internet was intended to be? Also, how does this apply to front-end apps? They're a lot closer to native apps than they are to "the internet". That is, you fetch them from the internet, but after that, there's nothing else about them that relates to the internet at all. ---------------------------------------------------------------------------------------------------- [23:24:09] Elia Schito(@elia):@/all opal 0.9.0.beta1 is out, now's the time to test your apps and libs against it! :D https://twitter.com/rubygems/status/656214540363911168 changes: https://github.com/opal/opal/blob/master/CHANGELOG.md#090-edge ---------------------------------------------------------------------------------------------------- [23:25:31] Elia Schito(@elia):also any help in writing a blog post for 0.9 on opalrb.org would be appreciated :smile: ---------------------------------------------------------------------------------------------------- [23:41:21] Ryan Stout(@ryanstout):@elia nice work! ---------------------------------------------------------------------------------------------------- [23:41:27] Ryan Stout(@ryanstout)::clap: ---------------------------------------------------------------------------------------------------- [23:41:38] Ryan Stout(@ryanstout):I can help with a blog post if you need it ---------------------------------------------------------------------------------------------------- [23:41:53] Elia Schito(@elia):That would be awesome! ---------------------------------------------------------------------------------------------------- [23:42:08] Ryan Stout(@ryanstout):what were you thinking for a blog post? ---------------------------------------------------------------------------------------------------- [23:43:07] Elia Schito(@elia):Presenting the release, listing the new features, maybe some highlights, something that can be shared and make it to twitter/reddit/hn/… :) ---------------------------------------------------------------------------------------------------- [23:45:59] Ryan Stout(@ryanstout):cool, I'm pretty busy today, but I should have sometime tomorrow if that works. ---------------------------------------------------------------------------------------------------- [23:47:58] Elia Schito(@elia):no rush, the timeline is just after the 0.9 release, I think it will take a couple of weeks at least (a month?) to cycle betas and release candidates and have all major libs ready ---------------------------------------------------------------------------------------------------- [01:43:14] Jamie Gaskins(@jgaskins):@Thermatix I'll run a couple benchmarks comparing Opal vs JS, but I can guarantee you that, realistically, it doesn't matter. For example, people started using React.js because it allows them to write high-performance apps easily. An equivalent Clearwater app (a framework written with Opal — https://github.com/clearwater-rb/clearwater) is faster. ---------------------------------------------------------------------------------------------------- [01:51:23] Jamie Gaskins(@jgaskins):@Thermatix Deoptimizations in the JS VM like those that occur in React.js have far higher performance costs than the slight overhead incurred by Opal. I've submitted several PRs to Opal that do nothing more than remove deoptimizations, which is how Clearwater can run faster than React (anywhere from 20% to 100% faster, depending on the app). The only performance penalty you're really left with by using Opal is handling differences in scoping and truthiness between Ruby/JS. ---------------------------------------------------------------------------------------------------- [01:51:38] Jamie Gaskins(@jgaskins): And the best part is, if you think Opal is the bottleneck in a particular hot spot in your code, you can write it in JS to eke out the extra bit of performance you need. ---------------------------------------------------------------------------------------------------- [02:45:55] Jamie Gaskins(@jgaskins):@Thermatix here are a few quick benchmarks I checked (iterations per second for 5 seconds with a 1-second warmup, larger benchmark is better): https://gist.github.com/jgaskins/c5a066e12ad7bde48b22 Numeric operations aren't amazing in Opal, but you can see function calls and object instantiation are pretty damn good. If your app would be fast in JS, it'll be fast in Opal. ---------------------------------------------------------------------------------------------------- [12:35:49] giuan(@giuan): ---------------------------------------------------------------------------------------------------- [12:39:48] giuan(@giuan):Why does doc = `document` doc.JS[:title] = "title" work, bat document = `document` document.JS[:title] = "title" doesn't? (Opal 9.1beta) ---------------------------------------------------------------------------------------------------- [12:41:40] Elia Schito(@elia):@giuan you should wrap the code in triple backslashes or put it in a gist or some other service (pastebin.com or pastie.org) ---------------------------------------------------------------------------------------------------- [12:42:51] Elia Schito(@elia):but probably the problem with document = `document` is that it shadows `window.document` with a local `var` named `document` ---------------------------------------------------------------------------------------------------- [12:43:36] Elia Schito(@elia):Opal maps Ruby local variables to plain JS local variables ---------------------------------------------------------------------------------------------------- [12:54:58] giuan(@giuan):Ok it's ```document```. Also performance doesn't work, bat perform do. document is undefined `puts "document undefined" unless defined? document` -> document undefined. So its not possible to use variable named window, document, console, performance etc.. ? ---------------------------------------------------------------------------------------------------- [12:56:07] Elia Schito(@elia):I'd say you can use all of them but `window` and then access the others as `window.document` ---------------------------------------------------------------------------------------------------- [12:56:59] Elia Schito(@elia):or you can put them into globals (which they are already), e.g. $document = `document` ---------------------------------------------------------------------------------------------------- [13:14:54] giuan(@giuan):Thanks Elia! ---------------------------------------------------------------------------------------------------- [13:15:17] Elia Schito(@elia)::+1: ---------------------------------------------------------------------------------------------------- [13:33:45] Martin Becker(@Thermatix):interesting, so basically not much of a difference in speed at all, thanks, is clearwater faster then react.rb because react.rb is a wrapper whereas clearwater is written directly in opal? ---------------------------------------------------------------------------------------------------- [13:35:57] Elia Schito(@elia):@Thermatix actually I think @jgaskins was writing about React.js, which has code that the browser can't optimize ---------------------------------------------------------------------------------------------------- [13:37:18] Martin Becker(@Thermatix):I see, hmmm ---------------------------------------------------------------------------------------------------- [13:38:09] Martin Becker(@Thermatix):I remember reading a blog which had benchmarks in it, the benchmark was just rendering 1000 li tags, and react.js was faster then even native code at doing it ---------------------------------------------------------------------------------------------------- [13:38:34] Martin Becker(@Thermatix):so does that mean react.js is faster in some places and slower in others because it can't be optimised? ---------------------------------------------------------------------------------------------------- [13:39:39] Elia Schito(@elia):no, well, react.js skips dom manipulation until the last moment, and I think you meant that by "native code", the same does clearwater ---------------------------------------------------------------------------------------------------- [13:40:06] Martin Becker(@Thermatix):I seee ---------------------------------------------------------------------------------------------------- [13:40:14] Elia Schito(@elia):said that, comparing the speed of react and clearwater is comparing raw js speed ---------------------------------------------------------------------------------------------------- [13:40:14] Martin Becker(@Thermatix):hmmm ---------------------------------------------------------------------------------------------------- [13:40:23] Martin Becker(@Thermatix):I think I'll still stick to react.rb ---------------------------------------------------------------------------------------------------- [13:40:32] Elia Schito(@elia):that's why JS engine optimization are important ---------------------------------------------------------------------------------------------------- [13:40:33] Martin Becker(@Thermatix):but maybe for personal projects I'll try clearwater ---------------------------------------------------------------------------------------------------- [13:41:26] Elia Schito(@elia):that kind of speed matters depending on the kind of app ---------------------------------------------------------------------------------------------------- [13:41:44] Elia Schito(@elia):for most apps jquery is fine ---------------------------------------------------------------------------------------------------- [13:41:45] Martin Becker(@Thermatix):speed isn't that important for the app I'm building ---------------------------------------------------------------------------------------------------- [13:42:08] Martin Becker(@Thermatix):but it's complictated so having a front end framework to manage things like states is going to be super helpfull ---------------------------------------------------------------------------------------------------- [13:42:18] Elia Schito(@elia):and of course the fact the clearwater performs better doesn't make react slow, but just slower ---------------------------------------------------------------------------------------------------- [13:43:55] Martin Becker(@Thermatix):I know, react is fast ---------------------------------------------------------------------------------------------------- ############################## [2015-10-21] ############################## [14:36:42] Jared White(@jaredcwhite):Awesome sauce!

I care much less about runtimes than I do about the language, but someone might make the argument that the JS "runtime", node, etc. might be better at running Ruby code for certain things than the other runtimes are. Do you have any thoughts on the internals of Node running Opal vs. MRI, etc.? ---------------------------------------------------------------------------------------------------- [21:00:58] Jamie Gaskins(@jgaskins):@wied03: It's a cool idea. @vais set up some benchmarks to compare MRI vs Opal (via node, I think) execution speed. I haven't seen the benchmarks in a while, but I wonder what the new ones would look like with the performance enhancements that have gone in recently. Once we remove or minimize some of the other deoptimizations I've seen (such as methods like `String#gsub` wrapping the entire method in a `try` / `catch`), I think it would be pretty close in a lot of cases. I also wonder what the memory consumption would look like. ---------------------------------------------------------------------------------------------------- [21:05:41] Ryan Stout(@ryanstout):So question (not trolling): Is running general ruby code via opal on node possible? (like would it be possible to run bundler on node, considering that it uses a lot of file api's) I know node has the fs.readFileSync, but does that cause problems being sync? ---------------------------------------------------------------------------------------------------- [21:05:52] Ryan Stout(@ryanstout):is there a sync http api ---------------------------------------------------------------------------------------------------- [21:14:41] meh.(@meh):ryanstout, opal-browser does ---------------------------------------------------------------------------------------------------- [21:14:59] meh.(@meh):you just have to enable synchronous in Browser::HTTP::Request ---------------------------------------------------------------------------------------------------- [21:30:40] Jamie Gaskins(@jgaskins):@meh: I think he means does node.js do sync fetch? ---------------------------------------------------------------------------------------------------- [21:30:48] meh.(@meh):ah ---------------------------------------------------------------------------------------------------- [21:30:51] Jamie Gaskins(@jgaskins):… which I don't know the answer to, tbh. ---------------------------------------------------------------------------------------------------- [21:34:46] Jamie Gaskins(@jgaskins):@ryanstout: Latest docs seem to point to no: https://nodejs.org/api/http.html#http_http_request_options_callback ---------------------------------------------------------------------------------------------------- [21:35:02] Jamie Gaskins(@jgaskins):Doesn't seem to be an option for `sync: true` or anything like that. ---------------------------------------------------------------------------------------------------- [21:35:21] Ryan Stout(@ryanstout):ok ---------------------------------------------------------------------------------------------------- [21:35:30] Ryan Stout(@ryanstout):seems like those kind of issues would be pretty common in node ---------------------------------------------------------------------------------------------------- [21:35:32] Ryan Stout(@ryanstout):but maybe not ---------------------------------------------------------------------------------------------------- [21:37:15] Jamie Gaskins(@jgaskins):I dunno. I think all I/O in node is build around the same concept as on the client: run it async so you don't block anything else from happening. ---------------------------------------------------------------------------------------------------- ############################## [2015-10-22] ############################## [01:50:25] Brady Wied(@wied03):It wouldn't be too hard to write some wrapper code that blocks and makes it look synchronous, would it? If not, it might end up being in a C#/.NET situation where the Opal compiler would have to 'hide' the callbacks with async/await ---------------------------------------------------------------------------------------------------- [01:50:54] Brady Wied(@wied03):it is a nice feature of the last 2 C# compiler versions though. async code that reads/looks sync ---------------------------------------------------------------------------------------------------- [02:44:09] Ryan Stout(@ryanstout):@wied03 its mostly impossible to take an async api and make it sync without coroutines or threads, which node does not have (though there are some extensions) async/await in C# is available in ES7, but it changes the way you call methods, so it doesn't work with non-async/await aware code. ---------------------------------------------------------------------------------------------------- [02:44:15] Ryan Stout(@ryanstout):its a problem I've thought about a lot :-) ---------------------------------------------------------------------------------------------------- [03:07:37] Brady Wied(@wied03):@ryanstout - Would you be in the camp then that thinks Ruby (via Opal) on node (as a runtime) has some unique things to offer that MRI doesn't? Not a loaded question, just curious ---------------------------------------------------------------------------------------------------- [03:16:55] Jamie Gaskins(@jgaskins):I definitely think it'd be an interesting experiment. I wonder if it'd end up feeling a lot like EventMachine, for better or worse. I think EventMachine is pretty awesome, tbh, but it never took off primarily because you have to do everything differently to take advantage of async and so does every single gem you use that does I/O. :-\ ---------------------------------------------------------------------------------------------------- [03:28:28] Ryan Stout(@ryanstout):@wied03 I think it depends on what your doing. If we could get bundler working and more gems out of the box, I think it would be useful. But I'm not sure how practical that would be. ---------------------------------------------------------------------------------------------------- [03:58:18] Brady Wied(@wied03):One of the jruby guys had a decent prez on Ruby performance with MRI, JRuby, and RBX. It was easier for me to follow though because I think the JVM and its optimizations have been around longer and are more well known than node ---------------------------------------------------------------------------------------------------- [07:57:39] Elia Schito(@elia):One clear place opal+node is useful is with desktop apps like Electron and NW.js ---------------------------------------------------------------------------------------------------- [16:43:37] Brady Wied(@wied03):@jgaskins - What happened to thoughts you had about method optimization and try/catch? Working on a PR or anything? ---------------------------------------------------------------------------------------------------- [17:42:31] Forrest Chang(@fkchang):@/all anyone gotten javascript as node modules to work w/opal? ---------------------------------------------------------------------------------------------------- [19:08:22] Dan Allen(@mojavelinux):@fkchang Asciidoctor.js is published as a node module and uses Opal.

Haven't had time. ---------------------------------------------------------------------------------------------------- [17:30:47] Jamie Gaskins(@jgaskins):I'm also still unsure of where the try/catch comes from in methods whose bodies are wrapped entirely on a `try` block :-) ---------------------------------------------------------------------------------------------------- [19:58:49] Brady Wied(@wied03):@jgaskins - I can't find a try/catch on String#gsub with the latest code. Are there other examples? ---------------------------------------------------------------------------------------------------- [19:59:47] Brady Wied(@wied03):@jgaskins - wait, it was up on the same line, missed it, you're right, it's there ---------------------------------------------------------------------------------------------------- [20:04:57] Brady Wied(@wied03):@jgaskins - I suspected the reason is that's inserted by the compiler as part of 'returner' logic. I think in `String#gsub`, that's caused by a `return` inside a closure (probably lines 493, 499, and 403-506 in string.rb). I bet the 'returner' logic the compiler puts in was mainly meant to apply to returns inside Ruby blocks/procs/lambdas, not JS. ---------------------------------------------------------------------------------------------------- [20:13:42] Brady Wied(@wied03):@jgaskins - I was wrong again, it's coming from the Ruby return at the top of the gsub method (line 458). Going to a pure JS return there takes care of it - https://github.com/opal/opal/pull/1166 ---------------------------------------------------------------------------------------------------- [20:22:21] Brady Wied(@wied03):That was the only case in corelib that used `#{return ..}` from within JS but there might be others like this. I did search for `{try {` in the compiled code and the other cases I saw were in `string/encoding.rb` and `set.rb` but that was from pure Ruby code and since those are probably used less often, I'm not sure if they warrant optimizing ---------------------------------------------------------------------------------------------------- ############################## [2015-10-24] ############################## [03:19:36] Vais Salikhov(@vais):@wied03 brilliantly simple fix, kudos! ---------------------------------------------------------------------------------------------------- [16:26:53] Brady Wied(@wied03): I was due for an easy one I guess ---------------------------------------------------------------------------------------------------- [17:17:59] Brady Wied(@wied03):Has anyone thought of doing this before?

Some of these I have no idea why they aren't optimized. @jgaskins - Does that approach for checking optimization look like it's credible to you? ---------------------------------------------------------------------------------------------------- ############################## [2015-10-25] ############################## [01:24:41] Vais Salikhov(@vais):@wied03 great idea. Text is fine - it's a list, and the only part of the list you'd care about are the unoptimized methods. Output something like `String#[]`, etc. ---------------------------------------------------------------------------------------------------- [01:35:38] Vais Salikhov(@vais):@wied03 I imagine this would work the same way as rubyspec works now: have a white list of class#method items that are "allowed" to be not optimized, and fail the build if a class#method that's not on that list is not optimized. This would catch regressions, and would force one to add a class#method to the list explicitly if there's no other way to implement the method. This would also let us track progress on optimization, as the list gets shorter over time. Really cool. ---------------------------------------------------------------------------------------------------- [06:09:49] Jamie Gaskins(@jgaskins):@wied03 I like it. I'd read through that doc before, but I guess I missed that part because I didn't know about those directives in v8. :-) Nice work! ---------------------------------------------------------------------------------------------------- [06:12:15] Jamie Gaskins(@jgaskins):@vais I like that idea, because that'll help ensure that overall performance doesn't slip because someone accidentally committed something with a try/catch in a hot path. ---------------------------------------------------------------------------------------------------- [06:22:01] Jamie Gaskins(@jgaskins):It might be a good idea to make that run in its own process, though. That may already be the intended case, but just adding it here for posterity. The reason I mention it is that functions can get deoptimized for being too polymorphic. For example, if you call a function with more than some VM-specific number of different types of arguments (pretty sure in Safari it's 4, might be 3 in Chrome), it can decide to deoptimize the function because the cost (both performance and memory) of optimizing it for each different type of argument potentially outweighs the performance you gain from it. ---------------------------------------------------------------------------------------------------- [06:26:01] Jamie Gaskins(@jgaskins):In the Chrome profiler, the warning it gives for this is "Optimized too many times". ---------------------------------------------------------------------------------------------------- [15:37:00] Brady Wied(@wied03):@jgaskins isnt redux part of the immutable pendulum swing? It seems to strongly discourage mutating state in objects. ---------------------------------------------------------------------------------------------------- [20:23:57] Jamie Gaskins(@jgaskins):@wied03 It is, indeed. It's one place I like using immutability, though, because it allows O(1) cache invalidation on render. ---------------------------------------------------------------------------------------------------- [20:47:53] Jamie Gaskins(@jgaskins):It's more of a functional-core/imperative-shell thing than full immutable. The store modifies itself to change which object it uses to represent state, but that state object itself is treated as immutable. ---------------------------------------------------------------------------------------------------- [20:58:59] Jamie Gaskins(@jgaskins):I use caching pretty regularly in Clearwater and React apps. Not mutating the data structure you store state in lets you check whether an object has been modified by simply doing an identity comparison. ```ruby class TodoList include Clearwater::Component include Clearwater::CachedRender def should_render? previous !todos.equal?(previous.todos) end end ``` ---------------------------------------------------------------------------------------------------- ############################## [2015-10-26] ############################## [15:33:54] Brady Wied(@wied03):@meh or @elia - Is it consistent with Opal's direction to add an "async/await" keyword to Opal's Ruby 'keywords' that, under the hood, handle promise/callback stuff for you like the C# compiler or Babel ES7->ES6/5 tool does? ---------------------------------------------------------------------------------------------------- [15:35:05] meh.(@meh):@wied03 I'd rather not add keywords that aren't present in Ruby, if it's a library then I'm fine with it ---------------------------------------------------------------------------------------------------- [15:35:16] Elia Schito(@elia):right ---------------------------------------------------------------------------------------------------- [15:35:18] meh.(@meh):changing syntax means breaking tools ---------------------------------------------------------------------------------------------------- [15:36:23] Brady Wied(@wied03):yeah. I've wondered over the years why Ruby hasn't done anything with this. Maybe waiting for the hype over async to die down. Certainly a lot of people thinking they need async everywhere when they don't.

I see both Clearwater and Inesita solving the same problem: back-end-agnostic Opal front-end ( as opposed to Volt, which is in a league of its own). But it would be really interesting to hear your and @jgaskins perspectives. E.g. what prompted you to create Inesita, in what ways is it different from Clearwater, etc. :sparkles: ---------------------------------------------------------------------------------------------------- [16:28:11] Jamie Gaskins(@jgaskins):@vais: I was thinking of writing a blog post about it, actually.

So if my app lets users delete their accounts and the front-end app sends `DELETE /my_account`, I should go ahead and do it. ---------------------------------------------------------------------------------------------------- [14:50:14] Jamie Gaskins(@jgaskins):You’re right that you shouldn’t trust the client enough to delete anyone else’s accounts, though. ---------------------------------------------------------------------------------------------------- [14:51:49] Brady Wied(@wied03):I agree with you that if the client tells me to delete, I sort of have to assume I should do that. My point is that with more being done with JS, I already need to check that it's their account they are trying to delete even without marshalling ---------------------------------------------------------------------------------------------------- [14:52:12] Brady Wied(@wied03):frankly, even with no JS on the client side, I still need to not trust them ---------------------------------------------------------------------------------------------------- [15:00:24] Jamie Gaskins(@jgaskins):@wied03 Let’s assume `AccountDeletion` has no state at all because the user can only delete their own account; there’s no reason to have any state. So `AccountDeletion#call` is literally just `Browser::HTTP.delete ‘/my_account’`. If unmarshaling an object results in one of those objects and I send `call` to it, I’ve deleted my account. ---------------------------------------------------------------------------------------------------- [15:05:21] Brady Wied(@wied03):sure but what i'm trying to grasp is how is the threat of getting an unintended AccountDeletion unmarshal any different than getting an unintended HTTP.delete ? ---------------------------------------------------------------------------------------------------- [15:14:04] meh.(@meh):@iliabylich the biggest issue with supporting marshalling is it's a binary format ---------------------------------------------------------------------------------------------------- [15:16:16] meh.(@meh):and since you're in the browser and have json, you should use that instead ---------------------------------------------------------------------------------------------------- [15:16:34] meh.(@meh):they both support hooks to create classes, so you don't really need marshalling ---------------------------------------------------------------------------------------------------- [15:18:32] meh.(@meh):I honestly wouldn't be completely against adding marshal support ---------------------------------------------------------------------------------------------------- [15:18:52] meh.(@meh):but I think there are other areas of Opal that need love before marshalling can be considered ---------------------------------------------------------------------------------------------------- [15:21:58] Brady Wied(@wied03):@meh - Marshaling could be done in a different format though. Nothing says Opal would need to marshal into a byte stream like MRI/etc. do ---------------------------------------------------------------------------------------------------- [15:22:13] meh.(@meh):wied03, yeah but it would be pointless then, you already have json ---------------------------------------------------------------------------------------------------- [15:22:53] Brady Wied(@wied03):not exactly, I can't give an object graph to JSON, serialize it, then go back the other way with the same types intact ---------------------------------------------------------------------------------------------------- [15:23:01] meh.(@meh):wied03, yes you can ---------------------------------------------------------------------------------------------------- [15:23:16] meh.(@meh):I remember doing it ---------------------------------------------------------------------------------------------------- [15:23:31] meh.(@meh):I know because I fixed stdlib/json myself to do it ---------------------------------------------------------------------------------------------------- [15:24:14] Brady Wied(@wied03):this is the reason why things like the OJ GEM were made if I recall correctly ---------------------------------------------------------------------------------------------------- [15:24:19] Brady Wied(@wied03):but not for opal ---------------------------------------------------------------------------------------------------- [15:25:01] Brady Wied(@wied03):@meh - but that only works for built in types like Hash, array, etc. ---------------------------------------------------------------------------------------------------- [15:25:29] Brady Wied(@wied03):if I have some classes I create, I can't get back without writing a bunch of to_json or from_json code ---------------------------------------------------------------------------------------------------- [15:25:32] meh.(@meh):wied03, nope, you just have to define .json_create ---------------------------------------------------------------------------------------------------- [15:26:00] meh.(@meh):well of course, but you can just write a module that defines them to your liking ---------------------------------------------------------------------------------------------------- [15:26:29] meh.(@meh):I did it for lissio ---------------------------------------------------------------------------------------------------- [15:26:30] Brady Wied(@wied03):hmm, i didn't see json_create until you mentioned it ---------------------------------------------------------------------------------------------------- [15:27:00] Brady Wied(@wied03):that said, in my case, i'm serializing in MRI and deserializing in Opal, so I had to write my own ---------------------------------------------------------------------------------------------------- [15:27:36] Brady Wied(@wied03):but I suppose if I implemented some of the json_create stuff on the MRI side, I could cut out some code ---------------------------------------------------------------------------------------------------- [15:29:51] Brady Wied(@wied03):This is mainly just me reasoning through this, but I don't get the threat vector for this (as in controlled attribute) type of marshaling, which I guess is really serialization. I do think it would be worrisome (if it were some how implemented in Opal with a browser, hard to see how), to do binary marshaling and sent that to a server running MRI. I perceive the danger there to be that you're giving the marshalled bits fairly low level access to your memory ---------------------------------------------------------------------------------------------------- [15:32:27] Brady Wied(@wied03):I really have the same problem that @ryanstout does in my tinkering, which is I have object X on the MRI side and I want to represent it on the browser side (or vice versa), without having to define a chain of to_json/from_json. It looks like the json_create stuff might ease the Opal side of the problem ---------------------------------------------------------------------------------------------------- [15:33:15] meh.(@meh):wied03, it's just a matter of defining json_create ---------------------------------------------------------------------------------------------------- [15:33:18] meh.(@meh):everything works then ---------------------------------------------------------------------------------------------------- [15:33:54] meh.(@meh):wied03, https://github.com/meh/lissio/blob/master/opal/lissio/model.rb#L216-L235 ---------------------------------------------------------------------------------------------------- [15:34:00] meh.(@meh):that's it ---------------------------------------------------------------------------------------------------- [15:35:10] Ilya Bylich(@iliabylich):@meh But what about passing objects from MRI to Opal?

I mean, it's ugly, but seems to be possible ---------------------------------------------------------------------------------------------------- [15:41:10] meh.(@meh):iliabylich, if your json_create doesn't do anything that could be a security hole, yeah ---------------------------------------------------------------------------------------------------- [15:42:09] Brady Wied(@wied03):I didn't know MRI had JSON.load, interesting, https://www.ruby-lang.org/en/news/2013/02/22/json-dos-cve-2013-0269/ and what you said clarified it for me ---------------------------------------------------------------------------------------------------- [15:43:45] meh.(@meh):didn't even know it had a CVE ◕ ◡ ◔ ---------------------------------------------------------------------------------------------------- [15:49:40] meh.(@meh):wied03, in general, any automatic object creation with non-validated input, is a very bad idea ---------------------------------------------------------------------------------------------------- [15:52:55] Brady Wied(@wied03):I don't dispute that, but it comes down to where the validation is done. I was never suggesting that it not be validated ---------------------------------------------------------------------------------------------------- [15:53:14] Brady Wied(@wied03):I agree though that if it really is automatic, you lose the chance to validate ---------------------------------------------------------------------------------------------------- [16:11:12] Brady Wied(@wied03):seems like there still might be an opportunity to do something in this space, maybe like a graphQL opal client?? ---------------------------------------------------------------------------------------------------- [16:27:14] Brady Wied(@wied03):@meh - By this logic, is Opal is "vulnerable" to the issue the CVE pointed out. MRI will not use the `json_class` when you call `JSON::parse`, it returns a hash every time unless you use `JSON::load`. Opal on the other hand is paying attention to it and instantiating an object of that class ---------------------------------------------------------------------------------------------------- [16:27:34] meh.(@meh):wied03, that's definitely a bug ---------------------------------------------------------------------------------------------------- [16:28:55] Brady Wied(@wied03):I suppose in the server->client case, it's not a big issue, but Opal might eventually be used the other way, in which case I guess stdlib should offer parse AND load and behave accordingly, right ? ---------------------------------------------------------------------------------------------------- [16:29:19] meh.(@meh):wied03, personally, I see using Opal outside the browser like an awful idea ---------------------------------------------------------------------------------------------------- [16:29:32] meh.(@meh):so I don't even care about that case, but it's a bug since it's not consistent with MRI ---------------------------------------------------------------------------------------------------- [16:31:08] Brady Wied(@wied03):that goes back to that runtime debate ---------------------------------------------------------------------------------------------------- [16:31:54] Brady Wied(@wied03):I still don't have an opinion there but I think it's good to think about it, because people will ask those questions ---------------------------------------------------------------------------------------------------- [16:38:58] Brady Wied(@wied03):Parked the issue in https://github.com/opal/opal/issues/1174 - @jgaskins, @meh - thanks for the conversation, reminded me of a few important things ---------------------------------------------------------------------------------------------------- [16:49:19] Jamie Gaskins(@jgaskins)::+1: ---------------------------------------------------------------------------------------------------- [16:49:59] Ryan Stout(@ryanstout):@wied03 in volt we use json to serialize. It would be nice to be able to send objects from server to client (not the other way for obvious security reasons), but it's not really something we need. We made a simple EJSON parser (thing meteor made up) that adds time and binary to json. Which works for now. ---------------------------------------------------------------------------------------------------- [22:24:19] Martin Becker(@Thermatix):I have a question on stack that you lot might be able to answer, I've tried to do this twice already but it hasn't worked. ---------------------------------------------------------------------------------------------------- [22:24:22] Martin Becker(@Thermatix):http://stackoverflow.com/questions/33425460/same-class-but-different-behaviour-depending-on-whether-its-running-on-opal-or ---------------------------------------------------------------------------------------------------- [22:33:40] Jamie Gaskins(@jgaskins):@Thermatix Answering here because the SO login form is broken: Are you loading both classes from a directory that's in both client-side and server-side load paths? For example, if you're running on Rails and you're loading both from `app/shared`, just load one from `app/models` and the other from `app/assets/javascripts`. ---------------------------------------------------------------------------------------------------- [22:34:09] Jamie Gaskins(@jgaskins):If you're already not sharing load paths, they can have the same filename and it won't conflict. ---------------------------------------------------------------------------------------------------- [22:36:07] Martin Becker(@Thermatix):that's not the issue, I want to have a standardised way of defining them(fields and matching type), and since they exist on both the back and front ends (in different forms) I want to have a way to define them easily without having to define two seprate files for each pair. ---------------------------------------------------------------------------------------------------- [22:40:16] Jamie Gaskins(@jgaskins):@Thermatix You could use `if RUBY_ENGINE == 'opal'`, but I don't see how that's any better than two separate files. You're defining two entirely separate classes. ---------------------------------------------------------------------------------------------------- [22:41:21] Martin Becker(@Thermatix):so there's no way to do an isomorphic class? ---------------------------------------------------------------------------------------------------- [22:42:29] Jamie Gaskins(@jgaskins):@Thermatix There is, but this isn't isomorphic. You're running entirely different code on each platform. ---------------------------------------------------------------------------------------------------- [22:42:40] Jamie Gaskins(@jgaskins):The only thing they share is the name ---------------------------------------------------------------------------------------------------- [22:42:53] Martin Becker(@Thermatix):how would I do that then? ---------------------------------------------------------------------------------------------------- [22:44:57] Jamie Gaskins(@jgaskins):Are you using Rails? ---------------------------------------------------------------------------------------------------- [22:45:03] Martin Becker(@Thermatix):I am not ---------------------------------------------------------------------------------------------------- [22:45:05] Martin Becker(@Thermatix):sinatra ---------------------------------------------------------------------------------------------------- [22:46:01] Jamie Gaskins(@jgaskins):In that case, you can just put the server-side implementation where your server-side models go and your client-side implementation inside your assets directory. ---------------------------------------------------------------------------------------------------- [22:48:11] Martin Becker(@Thermatix):I see ---------------------------------------------------------------------------------------------------- [22:48:14] Martin Becker(@Thermatix):well, thanks at any rate ---------------------------------------------------------------------------------------------------- [22:50:43] Martin Becker(@Thermatix):also cup-ramen > pot noodle ---------------------------------------------------------------------------------------------------- [10:57:17] Ilya Bylich(@iliabylich):Is there a chance for Opal to support `Marshal.load/dump`? ---------------------------------------------------------------------------------------------------- [10:58:23] Ilya Bylich(@iliabylich):It would be nice to have an ability to pass some objects like `Struct/OpenStruct` (or even more complex) directly from server to the client ---------------------------------------------------------------------------------------------------- [13:00:07] Vais Salikhov(@vais):@iliabylich it's a minefield ---------------------------------------------------------------------------------------------------- [13:00:26] Vais Salikhov(@vais):security-wise AFAIK ---------------------------------------------------------------------------------------------------- [13:00:59] Ilya Bylich(@iliabylich):@vais I'm not talking about sending marshalled stuff to the server, only about server -> client ---------------------------------------------------------------------------------------------------- [13:02:58] Ilya Bylich(@iliabylich):But still, if something gives you an ability to make a potential vulnerability , it doesn't mean that it should not be implemented at all :smile: ---------------------------------------------------------------------------------------------------- [13:03:54] Vais Salikhov(@vais):Yeah, but having `Marshal` in Opal has been on @ryanstout's wish-list for a long time :wink2: ---------------------------------------------------------------------------------------------------- [13:04:39] Vais Salikhov(@vais):@meh may be able to explain better what the challenges are, I'm not sure to be honest... ---------------------------------------------------------------------------------------------------- [13:22:29] Ilya Bylich(@iliabylich):I've seen a node module https://github.com/instore/node-marshal - it seems to be working on simple cases, so I'm wondering why all the Marshal stuff is in unsupported section ---------------------------------------------------------------------------------------------------- [13:25:45] Jamie Gaskins(@jgaskins):@iliabylich If you're using Rails, you can use the `gon` gem to pass JSON-serialized objects from server to client. Then on the client side, it's just: ```ruby MyModel.new(Hash.new(`gon.things`)) ``` I do this a lot in JS and I've started using it in Clearwater apps pretty simply. ---------------------------------------------------------------------------------------------------- [13:27:56] Ilya Bylich(@iliabylich):@jgaskins Yeah, but it covers only simple cases, for every model you have to write your own `fromJSON` method (or custom `to_json` on the server) ---------------------------------------------------------------------------------------------------- [13:38:34] Jamie Gaskins(@jgaskins):@iliabylich Sort of. Rather than making serialization a model-level concern, I'd much rather have a serializer to take it back and forth between JSON. But yes, you would have to handle conversion between them. This isn't a bad thing, though. If you're expecting a specific set of objects from `gon` or an HTTP request, you can be sure that's exactly what you get if you're doing your own deserialization or raise an exception if that's not what you got. You don't have that guarantee when unmarshaling data. ---------------------------------------------------------------------------------------------------- [13:48:54] Brady Wied(@wied03):I recently rolled my own simple marshaller. JSON serialization (on its own) didn't satisfy me because it doesn't store type metadata, etc. I would have to tell each object how to deserialize itself. I ended up writing something that stored `{class: Something, value: 'something'}`. I use JSON as the format though. It's a little verbose but my developer time is more important (in my opinion :smile: ) ---------------------------------------------------------------------------------------------------- [13:49:52] Brady Wied(@wied03):In that sense, I do think marshaling, when you control both sides, could be useful for Opal, but it would probably need to be a JSON/text representation of the object rather than binary ---------------------------------------------------------------------------------------------------- [14:05:57] Jamie Gaskins(@jgaskins):It could definitely be useful, but I get nervous when talking about using marshaling because it’s an opaque process that results in arbitrary objects. Unmarshaling (well, YAML deserialization) values coming in from outside became one of the top security vulnerabilities ever in Rails. In my experience, if someone doesn't want to put in the effort to define a serializer to go back and forth between JSON, they’re not very likely to put in the effort to ensure the result is what they’re expecting, either. ---------------------------------------------------------------------------------------------------- [14:12:30] Jamie Gaskins(@jgaskins):Maybe that’s just fear of people doing stupid things they won’t actually do, but a decade of consulting and having to fix code that used things like `Marshal.dump` because it was fewer keystrokes really pushes me to want to make the good idea easier than the bad idea. ---------------------------------------------------------------------------------------------------- [14:16:29] Brady Wied(@wied03):I think there is a big difference though between using marshaling between browser and server with your code on both sides and using marshaling for service integration with 3rd parties. The latter is crazy ---------------------------------------------------------------------------------------------------- [14:17:14] Brady Wied(@wied03):if it's my own code, I can put malicious stuff in the code anyways (without it sneaking in via an unmarshal call) ---------------------------------------------------------------------------------------------------- [14:18:10] Brady Wied(@wied03):I agree that binary marshaling is more dangerous though ---------------------------------------------------------------------------------------------------- [14:19:17] Jamie Gaskins(@jgaskins):I don’t know enough about the `Marshal` format to know if there’s a way to format a string attribute of that object that could be supplied by a user (say, the `body` attribute of a serialized chat message) that could get it interpreted as a marshaled object instead of a string. ---------------------------------------------------------------------------------------------------- [14:24:46] Jamie Gaskins(@jgaskins):@wied03 I do agree with you, but I’m not confident enough in any marshaling format that I would want to trust an opaque unmarshaling process from string to arbitrary objects with anything that has any attributes supplied by arbitrary users. With JSON, at least I know I can _only_ get a hash/array/string/number out of it. That gives me a lot more confidence in it. ---------------------------------------------------------------------------------------------------- [14:28:25] Ilya Bylich(@iliabylich):@jgaskins In MRI there are marshaling hooks (`marshal_dump/marshal_load`) that are invoked after object is built - this is probably the only dangerous place. No hooks - no code invocation. De-marshaling goes like `instance = SomeClass.allocate; instance.instance_variable_set(:@ivar, ...nested vars...)` + hooks ---------------------------------------------------------------------------------------------------- [14:31:57] Brady Wied(@wied03):I suppose the code I rolled is kind of a middle ground. I explicitly enlist classes in it and I explicitly say which attributes go in. And in the end, since I lack memory representation control, I'm ultimately just setting class attributes from a hash ---------------------------------------------------------------------------------------------------- [14:33:15] Brady Wied(@wied03):My code might be a giant turd for all I know, but I was looking for something to ease my isomorphic experiment ---------------------------------------------------------------------------------------------------- [14:35:55] Brady Wied(@wied03):In other news, it's not quite actual GEM worthy yet (still need to resolve a few more of their specs), but I've got https://github.com/wied03/opal-factory_girl working to build test objects for my client side code. No AR support of course but I found factory girl convenient for building test objects even w/o persistence ---------------------------------------------------------------------------------------------------- [14:35:57] Jamie Gaskins(@jgaskins):@iliabylich Not exactly. The dangerous part is when two objects in the system have a method with the same name but do different things. So, for example, if you’re expecting to run `Foo#call`, but instead of a `Foo`, you got back an `AccountDeletion` service object from unmarshaling, then the user’s browser requests that the server delete their account. ---------------------------------------------------------------------------------------------------- [14:37:47] Brady Wied(@wied03):@jgaskins - Interesting point. From a threat vector standpoint though, doesn't that presuppose that you've managed to get untainted JS from an initial payload but a subsequent AJAX request was man in the middled, etc. ? ---------------------------------------------------------------------------------------------------- [14:41:01] Jamie Gaskins(@jgaskins):@wied03 Nah, that’s kinda what I was getting at before. If some container object has an attribute you thought was a string, but that string can trick the unmarshaler into thinking it’s actually another type of object. I don’t know if this can happen, but I don’t trust it not to. ---------------------------------------------------------------------------------------------------- [14:45:40] Brady Wied(@wied03):You kind of have to not trust the client irrespective of marshalling, right?

HTTPS is usually handled by the web server (apache, nginx) that proxies to your application server (webrick, thin, puma). If you expose your application server directly to the interwebs (without a front proxy), you *can* make webrick/thin/puma handle https for you. This is not how it's usually done for production apps, but each of these rack servers supports https. ---------------------------------------------------------------------------------------------------- [13:13:47] Martin Becker(@Thermatix):I c so beyond changing the protocol to https, I don't have to do anything else? ---------------------------------------------------------------------------------------------------- [13:14:10] Martin Becker(@Thermatix):how do I ensure that the protocol is set to http when doing an ajax request in opal? ---------------------------------------------------------------------------------------------------- [13:14:20] Martin Becker(@Thermatix):I'm using the jquery library for ajax requests ---------------------------------------------------------------------------------------------------- [13:17:35] Elia Schito(@elia):@Thermatix you still need the certificate, I suggest finding a tutorial of some kind depending on what you need (e.g. https://duckduckgo.com/?q=https+ruby+server+setup&t=osx&ia=qa) ---------------------------------------------------------------------------------------------------- [13:31:50] Vais Salikhov(@vais):@Thermatix correct, once https is set up on the server side, all you have to do it use https:// urls instead of http://. Opal does not care about that, and neither does jquery. If you load the initial html page over https, you can make ajax calls to relative urls (no need to specify https etc), and these requests will be going through https. Hope this makes sense. In addition to what @elia said, you can try to use a self-signed SSL certificate to test with. The browser will complain that the connection is not secure (since your self-signed certificate does not come from a "trusted" source), but that's ok for testing purposes. ---------------------------------------------------------------------------------------------------- [13:34:27] Martin Becker(@Thermatix):can I use opal to then ensure that the protocol is set to https in the first place? ---------------------------------------------------------------------------------------------------- [13:34:56] meh.(@meh):just do not expose a clear-text port ---------------------------------------------------------------------------------------------------- [13:42:02] Vais Salikhov(@vais):I think you can check this client-side, but a better approach is what @meh suggested: either do not expose a clear-text port (http port 80) at all, or check on the server-side if a request is using SSL and if not, redirect to the https URL. ---------------------------------------------------------------------------------------------------- [13:42:43] Vais Salikhov(@vais):@Thermatix I think the general theme here is: do not make encryption a client-side concern in any way :smile: ---------------------------------------------------------------------------------------------------- [13:47:09] Martin Becker(@Thermatix):ok ---------------------------------------------------------------------------------------------------- [14:04:11] Vais Salikhov(@vais):@elia re the `opal -R server my_code.rb` trick that you mentioned, I am getting `Empty reply from server` for `http://localhost:3000` What am I missing? ---------------------------------------------------------------------------------------------------- [14:05:08] Elia Schito(@elia):@vais not sure, I used it with a pipe: `pbpaste | opal -R server`, does it work that way? ---------------------------------------------------------------------------------------------------- [14:07:18] Vais Salikhov(@vais):let me try... ---------------------------------------------------------------------------------------------------- [14:14:19] Vais Salikhov(@vais):@elia my bad, the issue seems to be with my vagrant forwarded port (I decided to use Vagrant running Ubuntu even on my Mac, so I have the same environment everywhere. The jury is still out on whether this was a good idea :wink2:) ---------------------------------------------------------------------------------------------------- [14:15:08] Vais Salikhov(@vais):As they say, you can always add another layer of indirection. ---------------------------------------------------------------------------------------------------- [14:15:18] Elia Schito(@elia):@vais go docker! ---------------------------------------------------------------------------------------------------- [14:15:40] Elia Schito(@elia):and eventually dind! ---------------------------------------------------------------------------------------------------- [14:16:09] Ilya Bylich(@iliabylich):@elia Is it possible to run generated tmp/mspec_node.rb this way?

I'm so tired of debugging through `node debug ...`. Thanks you so much :) ---------------------------------------------------------------------------------------------------- [14:31:25] Vais Salikhov(@vais):@elia hmm, so it's not my vagrant port forwarding, because other web things work (even just `ruby -run -e httpd . -p 3000`) It's gotta be something in that server cli runner, but wth? I'm not having a good day today, one mystery after another :smile: Thought maybe it's thin, but the same result with webrick. Better luck tomorrow perhaps. ---------------------------------------------------------------------------------------------------- [14:39:00] Elia Schito(@elia):@iliabylich the only regret is that I didn't publicize it more :) ---------------------------------------------------------------------------------------------------- [14:39:46] Elia Schito(@elia):@vais does it work from inside the machine? (pseudocode: `vagrant ssh curl localhost:3000`) ---------------------------------------------------------------------------------------------------- [14:48:48] Vais Salikhov(@vais):@elia yep, it does with curl inside the ssh session, but not from the outside (outside Chrome shows me the empty reply error). ---------------------------------------------------------------------------------------------------- [14:49:47] Vais Salikhov(@vais):I have used this vagrant setup with rails and sinatra before, using thin and webrick, so I have no idea what gives in this case. ---------------------------------------------------------------------------------------------------- [14:52:09] Martin Becker(@Thermatix):how do I do a setTimeout in opal without using native javascript? ---------------------------------------------------------------------------------------------------- [14:55:22] Elia Schito(@elia):@Thermatix you can use native (which is already required if you're using opal-jquery) in this way: `$$.setTimeout(-> { callback code }, 500)` ---------------------------------------------------------------------------------------------------- [14:56:25] Martin Becker(@Thermatix):thanks that worked ---------------------------------------------------------------------------------------------------- [15:08:13] Ilya Bylich(@iliabylich):@Thermatix As I remember, there is a method `delay` in opal-browser that takes a timeout and a block ---------------------------------------------------------------------------------------------------- [15:08:50] Ilya Bylich(@iliabylich):https://github.com/opal/opal-browser/blob/1336a869be2ff2aa1cbc57b323359b49cc47e7db/opal/browser/delay.rb#L58 method `after` ---------------------------------------------------------------------------------------------------- [15:09:41] Martin Becker(@Thermatix):thanks but I don't really want to install an entire gem just for a single function ---------------------------------------------------------------------------------------------------- [15:10:16] Martin Becker(@Thermatix):although... ---------------------------------------------------------------------------------------------------- [15:10:27] Martin Becker(@Thermatix):it might be worth using over the jquery library ---------------------------------------------------------------------------------------------------- [15:10:39] Martin Becker(@Thermatix):do I need jquery included for opal-browser? ---------------------------------------------------------------------------------------------------- [15:11:49] Ilya Bylich(@iliabylich):I don't think so, there is no `opal-browser` dependency in `opal-jquery`'s gemspec ---------------------------------------------------------------------------------------------------- [15:12:32] Martin Becker(@Thermatix):I mean do I need the jquery library to use opal-browser ---------------------------------------------------------------------------------------------------- [15:13:14] Ilya Bylich(@iliabylich):No, `opal-browser` is a wrapper for a native browser functionality ---------------------------------------------------------------------------------------------------- [15:13:46] Martin Becker(@Thermatix):AH ok, thats what I wanted to know, thanks. ---------------------------------------------------------------------------------------------------- [15:14:03] Martin Becker(@Thermatix):in that case I think I'm going to ditch the jquery library and switch to opal-browser ---------------------------------------------------------------------------------------------------- [15:19:53] meh.(@meh):Thermatix, opal-browser is cherry-pickable ---------------------------------------------------------------------------------------------------- [15:19:59] meh.(@meh):if you just need delay, just require 'browser/delay' ---------------------------------------------------------------------------------------------------- [15:20:04] meh.(@meh):and it will just be one class ---------------------------------------------------------------------------------------------------- [15:20:24] meh.(@meh):Thermatix, if you find it's not cherry-pickable enough and it's bringing in stuff you don't want, open an issue and I can make it more granular ---------------------------------------------------------------------------------------------------- [15:21:31] Martin Becker(@Thermatix):... it's saying that Browser::HTTP doesn't exist... ---------------------------------------------------------------------------------------------------- [15:21:40] meh.(@meh):because it's cherry-pickable ---------------------------------------------------------------------------------------------------- [15:21:44] meh.(@meh):require 'browser/http' ---------------------------------------------------------------------------------------------------- [15:21:57] Martin Becker(@Thermatix):i'm requiring 'browser' for the moment ---------------------------------------------------------------------------------------------------- [15:22:02] meh.(@meh):yes ---------------------------------------------------------------------------------------------------- [15:22:08] meh.(@meh):require 'browser'; require 'browser/http' ---------------------------------------------------------------------------------------------------- [15:22:20] Martin Becker(@Thermatix):I c, so I can't just require 'browser' ---------------------------------------------------------------------------------------------------- [15:22:29] meh.(@meh):'browser' requires only the basic browser stuff ---------------------------------------------------------------------------------------------------- [15:22:34] meh.(@meh):events, window, dom and cssom ---------------------------------------------------------------------------------------------------- [15:22:45] meh.(@meh):if you need additional stuff you also have to require it ---------------------------------------------------------------------------------------------------- [15:23:06] Martin Becker(@Thermatix):I seee ---------------------------------------------------------------------------------------------------- [15:23:22] Martin Becker(@Thermatix):and browser/delay is not a basic thing?

only the object itself? ---------------------------------------------------------------------------------------------------- [15:36:20] meh.(@meh):what object? ---------------------------------------------------------------------------------------------------- [15:38:30] Martin Becker(@Thermatix):lets say I'm doing: ```ruby Request.get("/api/forms/tree/#{id}") do |result| result.on :success do |response| puts response.inspect end end ``` it only displays `#` and nothing else I have to do `puts response.instance_variables` to see anything and I'd still have to iterate over each one to find the value of each attribute (if they are a public attribute at all). ---------------------------------------------------------------------------------------------------- [15:38:56] meh.(@meh):Thermatix, because inspect isn't implemented for it, pull request welcome ---------------------------------------------------------------------------------------------------- [15:39:58] Martin Becker(@Thermatix):isn't .inspect a basic ruby object method that standardly returns an object and it's instance variables and there values? ---------------------------------------------------------------------------------------------------- [15:45:07] Ilya Bylich(@iliabylich):@Thermatix Not for every single object. For example, for Object - yes, for String - no :) ---------------------------------------------------------------------------------------------------- [15:46:20] Martin Becker(@Thermatix): ---------------------------------------------------------------------------------------------------- [15:46:42] Martin Becker(@Thermatix): ---------------------------------------------------------------------------------------------------- [15:47:09] Martin Becker(@Thermatix):lets try that again ---------------------------------------------------------------------------------------------------- [15:47:25] Martin Becker(@Thermatix):I'm having some trouble sending JSON data to my server. ---------------------------------------------------------------------------------------------------- [15:47:53] Martin Becker(@Thermatix):here's my request class that makes the request: ```ruby require 'browser/http' class Request class << self %w{get post delete put patch head}.each do |http_verb| define_method http_verb do |*args,&block| self.make(http_verb,*args,&block) end end def make(type,url,payload=nil, &block) data_hash = {dataType: 'json'} data_hash.merge!({payload: payload.to_json})if payload Browser::HTTP.send type, url, *data_hash do |response| puts response.inspect # results = [response.status_code,response.json] if block_given? block.call(*response) else response end end end end end ``` ---------------------------------------------------------------------------------------------------- [15:48:25] Martin Becker(@Thermatix):and I'm using it like so: ```ruby def handle_validation event value = event.target.value ::Request.post("/api/forms/validate/#{Form.tree[:meta][:id]}",format_validation(event)) do |result| result.on :success do |response| self.tree = response.json set_pair_validation_field_value true, value set_validation_messages 'correct', false end result.on :failure do |response| set_pair_validation_field_value false set_validation_messages response.json[:data][:message], true end end end ``` ---------------------------------------------------------------------------------------------------- [15:48:45] Martin Becker(@Thermatix):the problem is that the server is receiving the data like this and erroring: ---------------------------------------------------------------------------------------------------- [15:49:27] Martin Becker(@Thermatix):`unexpected token at 'dataType=json&payload=%7B%22meta%22%3A%7B%22context%22%3A%22form.validation.check%22%2C%20%22target%22%3A%22form.account%22%7D%2C%20%22data%22%3A%7B%22field%22%3A%22user%20name%22%2C%20%22value%22%3A%22%22%7D%7D':` ---------------------------------------------------------------------------------------------------- [15:50:20] Martin Becker(@Thermatix):all `format_validation` does is just make sure it's in the correct hash structure, nothing more ---------------------------------------------------------------------------------------------------- [15:55:12] Ilya Bylich(@iliabylich):Check out this code: https://github.com/opal/opal-browser/blob/master/opal/browser/http/request.rb#L297 (parameters is your `data_hash`) ---------------------------------------------------------------------------------------------------- [15:56:00] meh.(@meh):Thermatix, the problem is HTTP::Request is not a normal object ---------------------------------------------------------------------------------------------------- [15:56:11] meh.(@meh):most of the stuff that you care about isn't in instance variables, but on the underlying native object ---------------------------------------------------------------------------------------------------- [15:58:24] Ilya Bylich(@iliabylich):When you pass a `Hash` to the `send` method, `Browser::HTTP::Request` encodes it as "key1=value1&key2=value2" (while you need json). The solution is: encode your data with `to_json` manually before passing it to `Browser::HTTP.send` ---------------------------------------------------------------------------------------------------- [15:59:08] Martin Becker(@Thermatix):I see ---------------------------------------------------------------------------------------------------- [15:59:28] Martin Becker(@Thermatix):does it pick up on JSON automaticly so you don't need to tell it that your sending JSON? ---------------------------------------------------------------------------------------------------- [15:59:37] Martin Becker(@Thermatix):automatically* ---------------------------------------------------------------------------------------------------- [15:59:38] Ilya Bylich(@iliabylich):@Thermatix The only http-related example in readme is a simple http get (without any parameters), so start reading the source :) ---------------------------------------------------------------------------------------------------- [15:59:39] meh.(@meh):Thermatix, nope ---------------------------------------------------------------------------------------------------- [16:00:45] Martin Becker(@Thermatix):so how do you tell it the content type? because `hash[:payload]` is a JSON string ---------------------------------------------------------------------------------------------------- [16:01:00] meh.(@meh):well, first of all you have to use post ---------------------------------------------------------------------------------------------------- [16:01:41] Martin Becker(@Thermatix):wait, I think I get it ---------------------------------------------------------------------------------------------------- [16:01:43] meh.(@meh):so just HTTP.post(url, hash) ---------------------------------------------------------------------------------------------------- [16:01:55] meh.(@meh):Thermatix, there is documentation ---------------------------------------------------------------------------------------------------- [16:02:29] meh.(@meh):Thermatix, http://www.rubydoc.info/github/opal/opal-browser/ ---------------------------------------------------------------------------------------------------- [16:02:34] meh.(@meh):almost everything has docs ---------------------------------------------------------------------------------------------------- [16:09:58] Martin Becker(@Thermatix):how do I set the content_type header on the request object when `Browser::HTTP.post` returns a promise and not the request object? It seems strange that `Browser::HTTP.post` only takes a url and the payload but not the payload type, I don't see how to set the `content_type` when I don't get access to the request object directly nor can you pass it into the request object. ---------------------------------------------------------------------------------------------------- [16:10:31] meh.(@meh):Thermatix, read the docs ---------------------------------------------------------------------------------------------------- [16:10:38] meh.(@meh):you just pass a block to post ---------------------------------------------------------------------------------------------------- [10:44:42] Michał Kalbarczyk(@fazibear):Inesita's livereload works! https://www.youtube.com/watch?v=7h6wn8tF9Rw ---------------------------------------------------------------------------------------------------- [10:45:32] Michał Kalbarczyk(@fazibear):Needs lot of cleanups but it works :tada: ---------------------------------------------------------------------------------------------------- [11:09:26] Vais Salikhov(@vais):@fazibear sweet! ---------------------------------------------------------------------------------------------------- [11:09:37] Elia Schito(@elia):@fazibear retweeted! ---------------------------------------------------------------------------------------------------- [12:21:40] Martin Becker(@Thermatix):whats inestia? ---------------------------------------------------------------------------------------------------- [12:31:05] Martin Becker(@Thermatix):is there an opal library for encrypting data before transport via ajax? ---------------------------------------------------------------------------------------------------- [12:31:26] meh.(@meh):@/alll need opinions on https://github.com/opal/opal/issues/1181 ---------------------------------------------------------------------------------------------------- [12:31:34] Martin Becker(@Thermatix):that also matches equivalent ruby gem library? ---------------------------------------------------------------------------------------------------- [12:32:16] meh.(@meh):Thermatix, not that I know of ---------------------------------------------------------------------------------------------------- [12:32:49] Martin Becker(@Thermatix):*sigh* ---------------------------------------------------------------------------------------------------- [12:33:04] Martin Becker(@Thermatix):can you point me in the right direction for encryption/decryption? ---------------------------------------------------------------------------------------------------- [12:33:24] meh.(@meh):what kind of encryption do you need? ---------------------------------------------------------------------------------------------------- [12:35:00] Martin Becker(@Thermatix):I want to encrypt form data before sending to the back end ---------------------------------------------------------------------------------------------------- [12:35:18] Martin Becker(@Thermatix):I also want to know of a good js password hasing library ---------------------------------------------------------------------------------------------------- [12:41:26] Vais Salikhov(@vais):@Thermatix what's wrong with using https?

Am I missing something (also is this the right place to ask about opal-rails?). Thanks ---------------------------------------------------------------------------------------------------- [16:40:53] Elia Schito(@elia):@rainkinz right place indeed! : ) Can you tell me more about the template you want to render and its path? ---------------------------------------------------------------------------------------------------- [16:45:11] Brendan Grainger(@rainkinz):sure ---------------------------------------------------------------------------------------------------- [16:47:33] Brendan Grainger(@rainkinz):I have a messages_controller with the following create method: ``` def create @message = Message.create!(message_params) render type: :js, locals: { messages_html: render_to_string(@message) } # render type: :js, locals: { messages_html: "from controller" } end ``` and a create.js.opal file in: app/views/messages/create.js.opal with the following code: ``` require 'opal-jquery' Document.ready? do puts "Adding message #{@message}" Element.find('#chat').append(messages_html) end ``` ---------------------------------------------------------------------------------------------------- [16:48:01] Brendan Grainger(@rainkinz):note that if I don’t call `render_to_string` in the controller the opal code is called ---------------------------------------------------------------------------------------------------- [16:48:36] Brendan Grainger(@rainkinz):so I think it’s actually a rails thing, but given the example here: https://github.com/opal/opal-rails#as-a-template I thought it might work ---------------------------------------------------------------------------------------------------- [16:49:14] Brendan Grainger(@rainkinz):thank you so much for your help by the way ---------------------------------------------------------------------------------------------------- [16:52:31] Elia Schito(@elia):Sorry, I don't see anything obvious, can you open an issue over at https://github.com/opal/opal-rails/issues/new ? ---------------------------------------------------------------------------------------------------- [16:53:08] Elia Schito(@elia):I'll add a spec for it and then try to find out what's wrong ---------------------------------------------------------------------------------------------------- [16:54:38] Brendan Grainger(@rainkinz):sure, by the way if I change: ``` render type: :js, locals: { messages_html: render_to_string(@message) } ``` to ``` render type: :js, locals: { messages_html: "from controller” } ``` the opal code is called. So I think it’s more of a rails thing and perhaps that I’m trying to render an erb template using render_to_string then call render again to get it to call the create.js.opal template ---------------------------------------------------------------------------------------------------- [16:59:33] Elia Schito(@elia):the interaction is really strange, gotta go now, be sure to post anything you find about it here or in the issue, thanks! ---------------------------------------------------------------------------------------------------- [16:59:49] Brendan Grainger(@rainkinz):will do.

I tried using `Opal.use_gem`. It seems to do what it says on the tin.

For some end-to-end encryption things, I need to use the `ruby-ecdsa` and `digest-sha3` gems, both on the server-side and the client-side. Both of these gems do not have any external dependencies, so I think they should be able to interace with Opal. How can I get Opal/opal-rails to compile these gems so they can be used in the client-side code? ---------------------------------------------------------------------------------------------------- [12:16:59] Ilya Bylich(@iliabylich):Does opal-rspec support `let`? ---------------------------------------------------------------------------------------------------- [12:36:37] Qqwy / Wiebe-Marten(@Qqwy):@iliabylich as it is used inside the spec (https://github.com/opal/opal-rspec/blob/ceb3bc658cdf333b85e86fb9cee0256270e19e9a/spec/opal/example_spec.rb) I believe it does. ---------------------------------------------------------------------------------------------------- [12:39:13] Ilya Bylich(@iliabylich):@Qqwy It's opal-rspec 0.5.0.beta2, I don't think that opal master uses it :( Thank you ---------------------------------------------------------------------------------------------------- [12:43:04] Ilya Bylich(@iliabylich):@elia Do specs in /spec/opal use mspec inside? ---------------------------------------------------------------------------------------------------- [12:45:53] Ilya Bylich(@iliabylich):sure, that's why there's no `let ` :smile: ---------------------------------------------------------------------------------------------------- ############################## [2015-11-11] ############################## [06:21:06] Forrest Chang(@fkchang):@/all I added react support to opal playground http://git.io/v8Sm7 ---------------------------------------------------------------------------------------------------- [06:21:43] Forrest Chang(@fkchang):will tabify it also ---------------------------------------------------------------------------------------------------- [13:23:33] Martin Becker(@Thermatix):@all how do I do chunked file-uploads in opal? ---------------------------------------------------------------------------------------------------- [13:24:01] Elia Schito(@elia):@Thermatix are you using opal-browser or opal-jquery? ---------------------------------------------------------------------------------------------------- [13:24:05] Martin Becker(@Thermatix):browser ---------------------------------------------------------------------------------------------------- [13:24:20] Martin Becker(@Thermatix):also ---------------------------------------------------------------------------------------------------- [13:24:44] Martin Becker(@Thermatix):is it possible for the backend (sinatra) to give a progress update every time it gets a chunk? ---------------------------------------------------------------------------------------------------- [13:25:03] Elia Schito(@elia):@Thermatix never tried, google says something? ---------------------------------------------------------------------------------------------------- [13:25:55] Martin Becker(@Thermatix):well, that part isn't important ---------------------------------------------------------------------------------------------------- [13:25:58] Martin Becker(@Thermatix):it's the file upload that is ---------------------------------------------------------------------------------------------------- [13:26:17] Martin Becker(@Thermatix):I was thinking of using the following code for moving the chunked data to a target location https://gist.github.com/sasimpson/1112739 ---------------------------------------------------------------------------------------------------- [13:27:33] Elia Schito(@elia):I'd rather search for a javscript in-browser example and then convert it to opal cc @meh ---------------------------------------------------------------------------------------------------- [13:28:09] Martin Becker(@Thermatix):hmm I seee ---------------------------------------------------------------------------------------------------- [14:25:41] Mitch VanDuyn(@catmando):@thermatix - indeed.. there are good jquery plugins for this... no need to write new, although a opal wrapper would be nice! ---------------------------------------------------------------------------------------------------- [14:34:44] Mitch VanDuyn(@catmando):@thermatix, and yes the backend can monitor the progress. I can give you detailed code example for a sinatra app that does this. It does require some apache plugins etc to work (at least pre html5) ---------------------------------------------------------------------------------------------------- [14:38:53] Martin Becker(@Thermatix):I'm currently doing something like this: https://gist.github.com/Thermatix/3a8138baf705b55a565c ---------------------------------------------------------------------------------------------------- [14:39:17] Martin Becker(@Thermatix):for the backend ---------------------------------------------------------------------------------------------------- [14:40:03] Martin Becker(@Thermatix):because I intend to push the uploaded file to a remote server (s3 most probably) ---------------------------------------------------------------------------------------------------- [14:40:16] Martin Becker(@Thermatix):it probably won't be exactly like this ---------------------------------------------------------------------------------------------------- [14:40:30] Martin Becker(@Thermatix):but I'm trying to make it remote server agnostic ---------------------------------------------------------------------------------------------------- [14:41:18] Martin Becker(@Thermatix):also @catmando cool, I Iook forward to seeing it ---------------------------------------------------------------------------------------------------- [14:41:48] Mitch VanDuyn(@catmando):okay... sure I can paste the code someplace, but there are some important things to understand. ---------------------------------------------------------------------------------------------------- [14:43:44] Mitch VanDuyn(@catmando):you will get MUCH BETTER performance if you client app pushes directly to the cloud service, and then once its there, you can pull onto the server and process. Why? because the cloud storage is highly optimized to receive your files rapidly, at low overhead. But if you send to your server you are tying up a server process for the whole upload story. So for best results it goes like this: ---------------------------------------------------------------------------------------------------- [14:44:08] Mitch VanDuyn(@catmando):1) client initiates an upload ---------------------------------------------------------------------------------------------------- [14:45:01] Mitch VanDuyn(@catmando):2) server provides a unique id (or you can just do a random hash on the client) ---------------------------------------------------------------------------------------------------- [14:45:37] Mitch VanDuyn(@catmando):3) client pushes the files directly to a cloud location named using the id. ---------------------------------------------------------------------------------------------------- [14:45:56] Mitch VanDuyn(@catmando):4) the cloud service will provide the incremental feedback ---------------------------------------------------------------------------------------------------- [14:46:13] Mitch VanDuyn(@catmando):5) once done the client notifies the server that there is new data waiting to process ---------------------------------------------------------------------------------------------------- [14:47:56] Mitch VanDuyn(@catmando):Lots of stuff out in google land explaining how to do this. Strongly suggest you do not try to re-invent this particular wheel, as it gets really tricky. ---------------------------------------------------------------------------------------------------- [15:47:04] Martin Becker(@Thermatix):is it possible to remote_require a js file? ---------------------------------------------------------------------------------------------------- [15:55:39] Elia Schito(@elia):@Thermatix yes, but you have to implement it yourself, there's a `remote_require` in `opal-parser`, but it's a sync request and fetches ruby code instead of js so it's probably not what you need ---------------------------------------------------------------------------------------------------- [15:56:06] Elia Schito(@elia):https://github.com/opal/opal/blob/c6ffbfee22c031e90f30adfd8daf7ac23650e430/stdlib/opal-parser.rb#L11-L19 ---------------------------------------------------------------------------------------------------- [15:57:15] Martin Becker(@Thermatix):hmmm ---------------------------------------------------------------------------------------------------- [16:04:56] Martin Becker(@Thermatix):Ok, so I found a solution here: https://gitter.im/opal/opal ---------------------------------------------------------------------------------------------------- [16:05:01] Martin Becker(@Thermatix):what I'm doing is: ---------------------------------------------------------------------------------------------------- [16:05:22] Martin Becker(@Thermatix):```ruby def load_library &block raise 'no provider_url present' unless @provider_url %x' url = #{@provider_url} var script = document.createElement("script") script.type = "text/javascript"; if (script.readyState){ //IE script.onreadystatechange = function(){ if (script.readyState == "loaded" || script.readyState == "complete"){ script.onreadystatechange = null; #{block.call} } }; } else { //Others script.onload = function(){ #{block.call} }; } script.src = url; document.getElementsByTagName("head")[0].appendChild(script); ' end ``` ---------------------------------------------------------------------------------------------------- [17:38:17] Martin Becker(@Thermatix):how do I convert `#` into a type that a standard file uploader can understand? ---------------------------------------------------------------------------------------------------- [17:39:13] Martin Becker(@Thermatix):with `file.name`, `file.type`, etc ---------------------------------------------------------------------------------------------------- [17:39:31] meh.(@meh):Thermatix, call `#to_n` ---------------------------------------------------------------------------------------------------- [17:39:40] Martin Becker(@Thermatix):ah, thanks! ---------------------------------------------------------------------------------------------------- [17:52:31] Martin Becker(@Thermatix):I can't find the file reader in opal-browser ---------------------------------------------------------------------------------------------------- [17:52:38] Martin Becker(@Thermatix):can some one link it? ---------------------------------------------------------------------------------------------------- [17:57:24] meh.(@meh):Thermatix, it's not implemented if I recall correctly ---------------------------------------------------------------------------------------------------- [17:57:29] meh.(@meh):shouldn't be hard to add tho ---------------------------------------------------------------------------------------------------- ############################## [2015-11-12] ############################## [21:54:58] meh.(@meh):1) it won't change the API, so no possible breaking for whatever reason ---------------------------------------------------------------------------------------------------- [21:55:15] meh.(@meh):2) if you're doing double thenning, you're already using a variable, so it doesn't make the chaining ugly/weird ---------------------------------------------------------------------------------------------------- [21:55:44] meh.(@meh):3) you know in the code you're using multiple thenning ---------------------------------------------------------------------------------------------------- [21:57:17] meh.(@meh):@Thermatix by the way I just noticed there's actually documentation on providing APIs using promises in promise.rb inline-doc ---------------------------------------------------------------------------------------------------- [21:59:24] Ryan Stout(@ryanstout):@meh so let me explain my use case, that might make it clearer.

For example, there's a difference between `p.then.catch` and `p.then; p.catch`. The first one can call `.catch` if a failure occurs anywhere in the chain, but the second catch won't be triggered if the failure occurs inside the `then`. ---------------------------------------------------------------------------------------------------- [19:52:51] meh.(@meh):ryanstout, jgaskins, fine, you've changed my mind ---------------------------------------------------------------------------------------------------- [19:53:05] Jamie Gaskins(@jgaskins):More info: https://ponyfoo.com/articles/es6-promises-in-depth ---------------------------------------------------------------------------------------------------- [19:53:28] Ryan Stout(@ryanstout):@meh not sure if it makes things easier, but that promise.rb library has a nice clean implementation. ---------------------------------------------------------------------------------------------------- [19:53:54] Ryan Stout(@ryanstout):it had a bit different api, and for some reason raised exceptions through on failure ---------------------------------------------------------------------------------------------------- [21:33:25] giuan(@giuan):@elia ` opal -I. main.rb` doesn't work!

Main aim is to speed up debugging and take advantage of how many things hook into Karma (and Karma's convenient spin up/throw away browser stuff). ---------------------------------------------------------------------------------------------------- [07:56:02] Iaroslav Kukharuk(@brbrr):Hi guys! I'm looking for a way to use external gems with opal i.e. `rest-client`. Im quite sure that I requiring that gem incorrectly: ``` require 'rest-client' Opal.append_path '/Users/brbrr/.rbenv/versions/2.2.0/lib/ruby/gems/2.2.0/gems/rest-client-1.8.0/lib' ``` Another question is how to make compiled js to run in console(node/browser) ---------------------------------------------------------------------------------------------------- [10:51:23] Martin Becker(@Thermatix):if you want it to work for opal you'll need to port it to opal compatible ruby, some of the code won't be compatible; for example dynamic requires won't work so will have to be changed to `require_tree` directive. ---------------------------------------------------------------------------------------------------- [10:52:43] Martin Becker(@Thermatix):second of all if you want to make HTTP requests I'd recommend using the HTTP client that comes with opal-browser it's super easy to use, here, in fact I'll post you my request module that I built on top of it: ```ruby require 'browser/http' class Request class << self %w{get post delete put patch head}.each do |http_verb| define_method http_verb do |*args,&block| self.make(http_verb,*args,&block) end end def make(type,url,payload=nil, &block) # data_hash = {dataType: 'json'} # data_hash.merge!({payload: payload.to_json})if payload Browser::HTTP.send type, url, payload.to_json do |request| request.content_type 'application/json' if block_given? block.call(*request) else request end end end end end ``` ---------------------------------------------------------------------------------------------------- [10:53:53] Martin Becker(@Thermatix):Why did I build this? Because I want to ensure anything is correctly formatted and I can do that here so now every method will share any current and future formatting requirements. ---------------------------------------------------------------------------------------------------- [11:01:13] Iaroslav Kukharuk(@brbrr):@Thermatix isn't `require 'browser/http'` is dynamic require? actually `rest-client` was used as an example, and Im just playing around with opal, not trying to solve something. In what way I could just use gem as-is? ---------------------------------------------------------------------------------------------------- [12:42:48] Martin Becker(@Thermatix):no, dynamic require means for example iterating over a `Dir['.']` blob and requiring each one ---------------------------------------------------------------------------------------------------- [12:45:55] Iaroslav Kukharuk(@brbrr):anyway generated js is not works for me: ``` require 'rest-client' Opal.compile("RestClient.get('http://goo.gl'") ``` ---------------------------------------------------------------------------------------------------- [12:46:40] Martin Becker(@Thermatix):try: ---------------------------------------------------------------------------------------------------- [12:48:29] Martin Becker(@Thermatix):```ruby script = <<- OPAL require 'rest-client RestClient.get('http://goo.gl' OPAL Opal.compile(script) ``` Though, I'm not sure that's the best way to do it, have you tried starting an opal server like in the example and then loading the scripts as assets and then lettings sprockets handle file processing and serving? ---------------------------------------------------------------------------------------------------- [13:03:52] Iaroslav Kukharuk(@brbrr):ok, now how could I execute that js with opal included? sorry about my kinda silly questions. I suppose I need to include opal.js lib in to js repl on machine where RestClient is reachable. so using opalrb.org/try is not an option ---------------------------------------------------------------------------------------------------- [13:08:44] Martin Becker(@Thermatix):you might want to try following this example to set a basic opal environment up: https://github.com/opal/opal/tree/master/examples/sinatra use this to append your paths to the opal server: ```ruby opal = Opal::Server.new {|s| s.append_path 'assets/javascripts/' s.main = 'application' } ``` set up opal variables: ```ruby sprockets = opal.sprockets prefix = '/assets/javascripts' maps_prefix = '/__OPAL_SOURCE_MAPS__' maps_app = Opal::SourceMapServer.new(sprockets, maps_prefix) # Monkeypatch sourcemap header support into sprockets ::Opal::Sprockets::SourceMapHeaderPatch.inject!(maps_prefix) ``` set up the opal header ```ruby opal_header = ::Opal::Sprockets.javascript_include_tag('application', sprockets: sprockets, prefix: prefix, debug: true) ``` and then set up a basic sinatra root: ```ruby get '/' do <<-HTML #{opal_header} HTML end ``` ---------------------------------------------------------------------------------------------------- [13:28:21] Martin Becker(@Thermatix):how do I push a value from embedded javascript to an opal function and or object? ---------------------------------------------------------------------------------------------------- [13:55:17] Martin Becker(@Thermatix):nvm figured it out ---------------------------------------------------------------------------------------------------- [14:10:03] Iaroslav Kukharuk(@brbrr):ah, I didnt look in to config.ru.

I haven't used karma, does it use webdriver under the hood? ---------------------------------------------------------------------------------------------------- [22:05:01] Brady Wied(@wied03):@ryanstout - No. It's not an integration test tool. It's solely for JS unit testing. Since it's good at spinning up browsers and several tools I use can hook into it, I'm exploring using it for debugging instead of the opal-rspec rake task or opal-rspec browser runner ---------------------------------------------------------------------------------------------------- [22:05:33] Brady Wied(@wied03):You pick what it should run tests in (Chrome, Phantom, Firefox, etc.).

I personally like the GEM packaging system better so I'd love rails-assets.org for NPM packages (not just Bower). I do think it's good to support the other direction (opal into NPM) as well though. ---------------------------------------------------------------------------------------------------- [17:28:18] Brady Wied(@wied03):@fkchang - I also don't see why Sprockets needs to go away in favor of webpack. commonjs/requirejs are not exactly relevant in my view because it's not an apples to apples comparison. Opal Ruby modules are already providing the "require" dependency functionality from a runtime perspective. Sprockets covers the actual file dependency piece. I think fixing source maps in concatenated files is on Sprockets' radar (see https://github.com/rails/sprockets-rails/issues/254). I can't make the argument that Sprockets is absolutely better than webpack. I just don't necessarily agree with the reasons in the blog post. ---------------------------------------------------------------------------------------------------- [19:13:01] Forrest Chang(@fkchang):@fazibear do mean does hot module replacement work for opalrb-loader? If so, https://github.com/zetachang/opalrb-loader/tree/master/examples/simple says yes ---------------------------------------------------------------------------------------------------- [19:36:21] George Plymale II(@ylluminarious):@fazibear re: awesome-opal, great job on that! i've been waiting for an awesome-opal for a while and, if iirc, others here like @elia have expressed interest in it too. ---------------------------------------------------------------------------------------------------- [21:16:08] Forrest Chang(@fkchang):@wied03 I think there are advantages to being "1st class citizen" of JS, but something that would let me have things like * hot module reloading * painless integration of npm js modules (is this actually possible?), -- for react.rb I want to use existing react.js modules, they are all npm distributed and usually ES6, so I always have to process some and the save that as sometihng I require. Extend this to every npm module. * the ability to package only the needed assets for an entry point vs "the whole world" approach that sprockets does. I think react-router is really trying to do this and only load the appropriate js needed for particular routes, which ought to improve start up times, etc. All of which webpack does, but if we can it else wise, that would be cool. I'm not bound to webpack, but it seems like it's what all the JS ppl are doing, certain the react folks which is where I'm spending a lot of time researching ---------------------------------------------------------------------------------------------------- [21:44:50] Brady Wied(@wied03):@fkchang - the 1st 2 bullets are good reasons IMO. Doesn't the 3rd one come back to AMD vs. not? One could make the case that sending all of the JS so it can be cached is better than having to go back to the server for bits and pieces. ---------------------------------------------------------------------------------------------------- [22:00:01] Elia Schito(@elia):@fazibear awesome! can you send a couple PRs to add the link to the README and to opalrb.org? ---------------------------------------------------------------------------------------------------- [22:00:24] Elia Schito(@elia):never realized there's so much stuff! ---------------------------------------------------------------------------------------------------- [22:23:33] meh.(@meh):@fazibear where's lissio? :(( ---------------------------------------------------------------------------------------------------- [22:51:04] Elia Schito(@elia):@meh re yardoc, I'll revert the API docs to yard and rewrite those I written in tomdoc ---------------------------------------------------------------------------------------------------- [22:51:39] meh.(@meh):lol ---------------------------------------------------------------------------------------------------- [22:52:20] Elia Schito(@elia):i still like the sdoc search more, but yes, I repent! :D ---------------------------------------------------------------------------------------------------- [22:54:34] Elia Schito(@elia):also I still delude myself in thinking I'll have time to port the sdoc search to yard :P ---------------------------------------------------------------------------------------------------- ############################## [2015-11-21] ############################## [00:03:01] Forrest Chang(@fkchang):@wied03 I actually support all the module systems allows webpack to do all 3, hot reload is useful because data is separate from the module definitions, npm are all packaged as modules, knowing which modules to load and just those have to do with knowing module dependencies ---------------------------------------------------------------------------------------------------- [00:11:00] Forrest Chang(@fkchang):@fazibear my mistake that example is a live reloader not hot module reloader.

Writing something like ``` ruby class Float < Numeric def self.===(other) %x{ if (!other.$$is_number) { return false; } return (other % 1) !== 0; } end end ``` breaks floats coersion (i.e. `1.to_f` returns a `Number` and `Opal.coerce_to!` throws an error) ---------------------------------------------------------------------------------------------------- [17:45:52] meh.(@meh):iliabylich, nope ---------------------------------------------------------------------------------------------------- [17:47:31] meh.(@meh):iliabylich, all numbers are float in js ---------------------------------------------------------------------------------------------------- [17:49:10] Ilya Bylich(@iliabylich):@meh I see, thanks ---------------------------------------------------------------------------------------------------- [17:49:24] meh.(@meh):they're actually double, but you get the point ---------------------------------------------------------------------------------------------------- [18:48:28] Ilya Bylich(@iliabylich):@meh How about wrapping each float on the compilation stage to `Float(number)` and modify `Kernel#Float` to: ``` ruby def Float %x{ float = (... previous code ...); float = new Number(float); float.$$is_float = true; return float; } end ``` Then `Float.===` may look like: ``` ruby def self.===(other) return (other.$$is_float) || ((other % 1) !== 0); end ``` Plus some changes in Math logic like ``` ruby def *(other) if Float === other Float(self * `#{other}.valueOf()`}) else # current logic end ``` After theses changes we will get only one difference with MRI: inline `number.0`, because it's not a compiled number and it doesn't have floating value.

Is it correct to say: * Native() pulls an object from Javascript to Ruby-land by creating wrapper (decorator) for a javascript object * .JS pokes in javascript Land using ruby style syntax * Native returns a Ruby Object and is executed at runtime * JS by itself returns nothing, even if it looks like a method. It is kind of syntactic sugar and is basically handled at compile time. Methods sent to JS usually yield the return value of the invoked javascript method/property ... which is a javascript object. ---------------------------------------------------------------------------------------------------- [11:16:00] Elia Schito(@elia):@bwl21 that's correct ---------------------------------------------------------------------------------------------------- ############################## [2016-01-19] ############################## [00:50:35] Cassio Godinho(@cpgo):@elia , Im very new to opal and front end in general.

I have been using the same old set of apps so long, I can't remember what you need to do to configure rails to convert the .rb files to .js (i guess) ---------------------------------------------------------------------------------------------------- [17:13:36] Mitch VanDuyn(@catmando):okay got it... found the note about having to use application.rb unless you want to manually load stuff. (which I dont) ---------------------------------------------------------------------------------------------------- [17:13:59] Mitch VanDuyn(@catmando):The only problem is it means converting the existing application.js file to rb syntax right? ---------------------------------------------------------------------------------------------------- [17:14:11] Mitch VanDuyn(@catmando):which might be a bit harder for the generator... ---------------------------------------------------------------------------------------------------- [19:06:32] Elia Schito(@elia):@catmando that's a problem that I'd like to solve for opal-rails too ---------------------------------------------------------------------------------------------------- [19:07:13] Mitch VanDuyn(@catmando):@elia - so we are just doing an Opal.load('components') and it seems to be working... ---------------------------------------------------------------------------------------------------- [19:07:19] Mitch VanDuyn(@catmando):but I have another question: ---------------------------------------------------------------------------------------------------- [19:07:38] Mitch VanDuyn(@catmando):I need to require browser and browser/interval ---------------------------------------------------------------------------------------------------- [19:07:44] Mitch VanDuyn(@catmando):but only on the client! ---------------------------------------------------------------------------------------------------- [19:07:46] Elia Schito(@elia):(the sprockets directives `//= require` only make files available to the opal module system) ---------------------------------------------------------------------------------------------------- [19:08:17] Elia Schito(@elia):use the special `if RUBY_ENGINE == 'opal'` ---------------------------------------------------------------------------------------------------- [19:09:37] Elia Schito(@elia):unless of course your server is nodejs :trollface: :smile_cat: ---------------------------------------------------------------------------------------------------- [19:09:50] Mitch VanDuyn(@catmando):exactly the problem ---------------------------------------------------------------------------------------------------- [19:09:57] Mitch VanDuyn(@catmando):anyway I figured it out: ---------------------------------------------------------------------------------------------------- [19:10:31] Mitch VanDuyn(@catmando):```ruby if React::IsomorphicBase.on_opal_client? require 'browser' require 'browser/interval' end ``` (because React.rb has those handy methods :-) ) ---------------------------------------------------------------------------------------------------- [19:15:05] Elia Schito(@elia):in opal 0.9 there's also `opal/platform` in stdlib that should correctly detect the JS platform and set `OPAL_PLATFORM` ---------------------------------------------------------------------------------------------------- [19:15:19] Elia Schito(@elia):`if OPAL_PLATFORM == 'nodejs'` ---------------------------------------------------------------------------------------------------- [22:03:41] Bernhard Weichel(@bwl21):@elia sorry, it was a typo here at gitter.

Eventually, Polished will provide a number of loosely-coupled components that comprise a front-end framework that plugs super easily into any standard Rails project. For most of it, I'm simply extracting some patterns and shortcuts I've used in my own Rails/Opal projects, so it's not just theoretical. :) Anyway, check out (star!) Polished: Knockout and let me know what you think! ---------------------------------------------------------------------------------------------------- [19:10:33] Loïc Boutet(@loicboutet):Great work :) ---------------------------------------------------------------------------------------------------- [19:11:15] Jared White(@jaredcwhite):Thanks @loicboutet :) ---------------------------------------------------------------------------------------------------- [19:11:44] Loïc Boutet(@loicboutet):I like react.rb, but it s always good to see alternatives :) ---------------------------------------------------------------------------------------------------- [19:11:51] Loïc Boutet(@loicboutet):The more the merrier :) ---------------------------------------------------------------------------------------------------- [21:09:56] ylluminate(@ylluminate):has anyone taken a look at lighttable and what it would take to add opal support? ---------------------------------------------------------------------------------------------------- [21:09:58] ylluminate(@ylluminate):https://youtu.be/52SVAMM3V78 ---------------------------------------------------------------------------------------------------- [21:57:07] Elia Schito(@elia): @jaredcwhite great to hear! ---------------------------------------------------------------------------------------------------- [22:07:11] ylluminate(@ylluminate)::+1: @jaredcwhite great to see! ---------------------------------------------------------------------------------------------------- [23:25:16] Forrest Chang(@fkchang): @ylluminate I haven't looked at lighttable in a while, last I looked it didn't seem that ruby development options for it were that far along, though, in theory, Opal could be possibly be easier, being that it compiles to JS ---------------------------------------------------------------------------------------------------- ############################## [2016-01-26] ############################## [17:35:22] Martin Becker(@Thermatix):All I have to do is `include Asset_Pipeline` into my main sinatra app class and ---------------------------------------------------------------------------------------------------- [17:35:32] Martin Becker(@Thermatix):do: ---------------------------------------------------------------------------------------------------- [17:35:40] Martin Becker(@Thermatix):```ruby config do set :root, File.expand_path('path/to/root/goes/here', __FILE__) set :opal_libs, %{ruta react.rb opal-browser} end include Asset_Pipeline ``` at minimum ---------------------------------------------------------------------------------------------------- [17:36:17] Martin Becker(@Thermatix):and I get full asset setup with opal paths appended and routes for taking care of assets ---------------------------------------------------------------------------------------------------- [17:36:28] Martin Becker(@Thermatix):with full mime type handling :P ---------------------------------------------------------------------------------------------------- [17:37:54] Martin Becker(@Thermatix):it also sets the JS compressor to yui and css to sass ---------------------------------------------------------------------------------------------------- [17:38:41] Martin Becker(@Thermatix):OH and it also sets up sprocket helpers ---------------------------------------------------------------------------------------------------- [02:34:29] Brady Wied(@wied03):@ylluminate @fkchang - lighttable sounds like trying to get back to what IDEs give us.

Do you plan to replace `self.$each(self.$each)` with something like `self.$each({ $$p: ...}`? Right now it looks a bit unclear why do you call an `$each` function and pass itself as an argument :smile: . But in general :+1: , calling compiled methods looks more natural now. ---------------------------------------------------------------------------------------------------- [14:07:59] Ilya Bylich(@iliabylich):By the way, why there's no issue with overwriting `$$p` on the function representing a ruby method (like `$each.$$p`). I mean, the following code should not work - https://gist.github.com/iliabylich/4af98e4508dced607d54 because you override an existing version of `$each.$$p` in the inner loop (but the code works well on the master) ---------------------------------------------------------------------------------------------------- [14:09:28] Elia Schito(@elia):@iliabylich that was just a quick way to keep going, eventually I'll update everything in the right way ---------------------------------------------------------------------------------------------------- [14:09:46] Elia Schito(@elia):Further down the road can be even better: ```js /* Generated by Opal 0.10.0.dev */ (function(Opal) { Opal.dynamic_require_severity = "error"; var OPAL_CONFIG = { method_missing: true, arity_check: false, freezing: true, tainting: true }; var BLK_1, self = Opal.top, $hash2 = Opal.hash2; Opal.add_stubs(['$div', '$span', '$text']); return self.$div($hash2(["class"], {"class": "foo"}), BLK_1 = {$$s: self, $$p: function(){ var self = BLK_1.$$s || this, BLK_2; return self.$span($hash2(["class"], {"class": "bar"}), BLK_2 = {$$s: self, $$p: function(){ var self = BLK_2.$$s || this; return self.$text("baz") }}) }}) })(Opal); ``` ---------------------------------------------------------------------------------------------------- [14:13:55] Ilya Bylich(@iliabylich):Looks pretty much like a ruby code :smile: ---------------------------------------------------------------------------------------------------- [14:14:35] Elia Schito(@elia):indeed, the hard part is dealing with rest, opt and kw args ---------------------------------------------------------------------------------------------------- [14:15:24] Elia Schito(@elia):but I think that once I have something funcional that part can be improved and simplified too ---------------------------------------------------------------------------------------------------- [14:17:27] Ilya Bylich(@iliabylich):Will stdlib suffer from this? I mean, it seems more difficult to write such a code in a pure JS, your PR shows that ---------------------------------------------------------------------------------------------------- [14:18:47] Elia Schito(@elia):@iliabylich can you expand with an example? ---------------------------------------------------------------------------------------------------- [14:22:33] Ilya Bylich(@iliabylich):I was thinking about the stuff like `self.$each.apply(self, args.concat([self.$each]))`, but it was almost the same before + you just said that you are going to replace `$each` here. And with the new approach there's no need to modify existing methods. Sorry, I'm making decisions too quickly. ---------------------------------------------------------------------------------------------------- [14:23:43] Elia Schito(@elia):no worries, it's good to have more eyes on this kind of stuff, to be sure I didn't overlook something :) ---------------------------------------------------------------------------------------------------- [14:24:38] Elia Schito(@elia):that piece would probably end up in `args.push({$$p: fun…})` where it's ok to modify `args` ---------------------------------------------------------------------------------------------------- [18:51:53] Jared White(@jaredcwhite):Greetings everyone. I'm musing on doing another Opalist newsletter this week, not sure if there's been much news of late. Just checking in if there's anything I should know about. ---------------------------------------------------------------------------------------------------- [20:17:48] Forrest Chang(@fkchang):@jaredcwhite u got my semi recent submission? I've a few posts in the queue, but not ready for a bit ---------------------------------------------------------------------------------------------------- [20:30:04] Forrest Chang(@fkchang):@all I wanna say, being able to grab react.js components from npm and using them w/just a little setup is really handy. Opal being able to play as a "1st class JS citizen" is key to it's widespread adoption, IMO ---------------------------------------------------------------------------------------------------- [20:45:33] Elia Schito(@elia):@jaredcwhite checkout hyalite from last rubykaigi, talk in jp tho ---------------------------------------------------------------------------------------------------- [22:35:44] Mitch VanDuyn(@catmando):@jaredcwhite @loicboutet and I gave a talk on react.rb.. His tutorial repo does a complete step by step conversion of a standard CRUD rails todo app to a reactive one. ---------------------------------------------------------------------------------------------------- [22:44:56] Mitch VanDuyn(@catmando):The other news embedded in that, is that we have made really nice progress in using rspec/capybara to unit test components. For example (from catprint's test suite) ```ruby require 'spec_helper' describe 'tweet component', :js => true do before(:each) do size_window(:small, :portrait) @tweet = FactoryGirl.build(:tweets).sample mount "Tweet", {tweet: @tweet}, {render_on: :server_only} end it "is a tweet-card" do page.should have_css('div.tweet-card') page.save_screenshot('a-tweet-card.png') end it "has the tweeter's img" do page.find('img.profile-image')['src'].should eq(@tweet[:user][:profile_image_url_https]) end end ``` and even more fun, here is from tests at the end of @loicboutet's tutorial chapter 1, insuring that the rails generator correctly installed reactive-record: ```ruby it 'reactive-record has been installed' do 5.times { FactoryGirl.create(:todo) } mount "RRTest" do class RRTest < React::Component::Base def render "#{Todo.all.count} Todos. First Title = #{Todo.all.first.title}" end end end page.should have_content("#{Todo.all.count} Todos. First Title = #{Todo.all.first.title}") end ``` In this case we write the component inline in the server side rspec test, and it gets recompiled by opal and sent down to the client to make sure we have reactive-record installed. ---------------------------------------------------------------------------------------------------- [22:45:57] Mitch VanDuyn(@catmando):@jaredcwhite However perhaps I should do a blog post and/or gem just for testing this month, and then have you mention that next month... ---------------------------------------------------------------------------------------------------- ############################## [2016-02-17] ############################## [00:24:20] Jared White(@jaredcwhite):@fkchang @elia @catmando cool stuff!

In https://github.com/opal/opal/pull/1358/files I've extracted it to the common parent class (which looks dirty). Do you think it's better to put them into a separate module or make one more intermediate class (like `NodeWithArgs`)? ---------------------------------------------------------------------------------------------------- [15:52:06] Ilya Bylich(@iliabylich):I'm asking about existing conventions on the project :smile: ---------------------------------------------------------------------------------------------------- [15:53:56] Elia Schito(@elia):@iliabylich had the same though and was wondering too, let's say that for now a mixed in module or a super class seems to be just the same, maybe tho I lean a bit more for a module with "pure" helpers rather then a superclass ---------------------------------------------------------------------------------------------------- [15:54:34] Elia Schito(@elia):where "pure" helpers means the less bound to the object state and internal methods as possible (i.e. more stuff passed as a method param) ---------------------------------------------------------------------------------------------------- [15:54:45] Ilya Bylich(@iliabylich):Alright, I'll make a class.

React.rb will also have flavored my ideas since I wrote the gist ---------------------------------------------------------------------------------------------------- [19:53:12] George Plymale II(@ylluminarious):@fkchang just curious: what do you mean by the opposing "standard" widgets? ---------------------------------------------------------------------------------------------------- [19:55:49] George Plymale II(@ylluminarious):btw, perhaps we should move this discussion to the [opal-phaser](http://gitter.im/orbitalimpact/opal-phaser) room so as not to clutter up this one ---------------------------------------------------------------------------------------------------- [20:15:58] Forrest Chang(@fkchang):@ylluminarious I'm thinking along the lines of these (these are Ruby-Tk widgets, ) * TkFrame Create and manipulate frame widgets * TkButton Create and manipulate button widgets * TkLabel Create and manipulate label widgets * TkEntry Create and manipulate entry widgets * TkCheckButton Create and manipulate checkbutton widgets * TkRadioButton Create and manipulate radiobutton widgets * TkListbox Create and manipulate listbox widgets * TkComboBox Create and manipulate listbox widgets * TkMenu Create and manipulate menu widgets * TkMenubutton Create and manipulate menubutton widgets * Tk.messageBox Create and manipulate a message dialog * TkScrollbar Create and manipulate scrollbar widgets * TkCanvas Create and manipulate canvas widgets * TkScale Create and manipulate scale widgets * TkText Create and manipulate text widgets * TkToplevel Create and manipulate toplevel widgets * TkSpinbox Create and manipulate Spinbox widgets * TkProgressBar Create and manipulate Progress Bar widgets * Dialog Box Create and manipulate Dialog Box widgets * Tk::Tile::Notebook Display several windows in limited space with notebook metaphor. * Tk::Tile::Paned Displays a number of subwindows, stacked either vertically or horizontally. * Tk::Tile::Separator Displays a horizontal or vertical separator bar. * Ruby/Tk Font, Colors and Images Understanding Ruby/Tk Fonts, Colors and Images ---------------------------------------------------------------------------------------------------- [20:17:43] Forrest Chang(@fkchang):doen't have to be exactly this set, but basically -- all the higher level widgets pretty much every UI toolkit has implemented before the Web sent us 40 years back in time to only thinking in markup and CSS ---------------------------------------------------------------------------------------------------- [20:18:16] George Plymale II(@ylluminarious):ok ---------------------------------------------------------------------------------------------------- [20:18:29] George Plymale II(@ylluminarious):lol, re: that last remark ---------------------------------------------------------------------------------------------------- [20:19:32] Forrest Chang(@fkchang):@ylluminarious that remark has been on my nerves for ages.

Now I remember that I had the same issue with opal and xml2abc.js. At this time, the author of the library (http://wim.vree.org/svgParse/xml2abc.html) fixed the issue in his library. But it leaves the question if something could be done in Opal to overcome this issue. ---------------------------------------------------------------------------------------------------- [23:34:00] Elia Schito(@elia):@iliabylich that's true, and they shouldn't! :) ---------------------------------------------------------------------------------------------------- [17:00:03] Bernhard Weichel(@bwl21):I try to use w2ui (w2ui.com) together with Opal. But as soon as I add ```html ``` to my page - even if I don't do anything with Opal, the stuff fails with the following message in the chrome console: ```javascript Uncaught Error: Syntax error, unrecognized expression: #layout_layout_panel_function (symbol) { var $a, self = this, $iter = TMP_4.$$p, block = $iter || nil; var array_size = arguments.length - 1; if(array_size < 0) array_size = 0; var args = new Array(array_size); for(var arg_index = 0; arg_index < array_size; arg_index++) { args[arg_index] = arguments[arg_index + 1]; } TMP_4.$$p = null; return $scope.get('Kernel').$raise($scope.get('NoMethodError').$new((function() {if ((($a = self.$inspect && !self.$inspect.$$stub) !== nil && (!$a.$$is_boolean || $a == true))) { return "undefined method `" + (symbol) + "' for " + (self.$inspect()) + ":" + (self.$$class) } else { return "undefined method `" + (symbol) + "' for " + (self.$$class) }; return nil; })(), symbol)); } > .w2ui-panel-content ```` I don't know where to raise this issue, with Opal or with w2ui. I think the issue is caused by something with "Array" being changed by Opal, on the other hand, w2ui also seems to do some advanced stuff ... ---------------------------------------------------------------------------------------------------- [17:08:42] Bernhard Weichel(@bwl21):This is the html file which fails: ```html
``` ---------------------------------------------------------------------------------------------------- [17:10:40] Ilya Bylich(@iliabylich):@bwl21 Getting the same error, but stack trace doesn't show any functions from opal... ---------------------------------------------------------------------------------------------------- [17:12:18] Bernhard Weichel(@bwl21):@iliabylich Yes, I did not even use a function from opal yet. But the error message show some code which is generated by Opal. It appears to me that Opal is redefining something in a way that it causes the issue. ---------------------------------------------------------------------------------------------------- [17:23:22] Ilya Bylich(@iliabylich):Well, the error comes from this place - https://github.com/vitmalina/w2ui/blob/1.4.0/src/w2layout.js#L745. The library iterates over an array using `for (var i in [])` and they don't check for `if hasOwnProperty(i)` ---------------------------------------------------------------------------------------------------- [17:23:52] Ilya Bylich(@iliabylich):I guess every library that has this code may conflict with opal ---------------------------------------------------------------------------------------------------- [17:24:03] Ilya Bylich(@iliabylich):@elia is it true? :smile: ---------------------------------------------------------------------------------------------------- ############################## [2016-02-26] ############################## [08:44:10] Bernhard Weichel(@bwl21):@elia do you have any idea how the issue could be solved on Opal - side? @iliabylich there is a fix in w2ui master branch. It is from August 2015, but not yet in an official release. ---------------------------------------------------------------------------------------------------- [09:01:32] Elia Schito(@elia):@bwl21 it can't be solved our side, the best you can do is asking them to fix it (which they seem to have already done) or monkey patch it ---------------------------------------------------------------------------------------------------- [09:24:22] Bernhard Weichel(@bwl21):@elia, maybe it is worth to add a word on this to the doucmentation , e.g. http://opalrb.org/docs/guides/v0.9.2/compiled_ruby.html or in the compatibilty section. ---------------------------------------------------------------------------------------------------- [09:25:37] Elia Schito(@elia):@bwl21 sounds like a good idea ---------------------------------------------------------------------------------------------------- [09:26:33] Zac Cassini(@zcassini):@bwl21 you might have a look at https://github.com/balmoral/opal-webix might satisfy your needs. ---------------------------------------------------------------------------------------------------- [09:35:33] Colin Gunn(@balmoral):@zcassini @bwl21 I seem to recall a similar problem somewhere in webix, but that was some time back.

Ruta will then go off and try to load the context, if it doesn't exist it will try (using the provided url template) to download the code and files for the context. it almost works, it does download the file but either I get that error OR I can't get the code to wait for the files to download before progressing ---------------------------------------------------------------------------------------------------- [21:18:50] Mitch VanDuyn(@catmando):@elia - don't you have a css DSL built into lissio?

There are gems in there that aren't needed by my gem. Any hints? ---------------------------------------------------------------------------------------------------- [15:41:35] Aaron Quamme(@aquamme):I'm pretty inexperienced with Ruby, so I apologize if I'm flubbing up something obvious here. ---------------------------------------------------------------------------------------------------- [15:45:38] Elia Schito(@elia):@aquamme you should avoid adding `$LOAD_PATH` paths to opal, as it contains a number of paths that are used for Ruby which aren't compatible, usually you just add the dir containing your application code with append path. ---------------------------------------------------------------------------------------------------- [15:46:25] Elia Schito(@elia):or if you're a library developer you add the path to your library, eg: https://github.com/fazibear/opal-virtual-dom/blob/master/lib/opal-virtual-dom.rb#L3 ---------------------------------------------------------------------------------------------------- [15:48:21] Elia Schito(@elia):Also the error says `TypeError: can't convert Array into String`, looks like you tried to add the whole `$LOAD_PATHS` array with `Opal.append_path` which instead only takes a single string ---------------------------------------------------------------------------------------------------- [15:49:13] Elia Schito(@elia):here's a rather simple usage example for Rack: https://github.com/opal/opal/blob/master/examples/rack/config.ru#L17 ---------------------------------------------------------------------------------------------------- [15:59:22] Aaron Quamme(@aquamme):Thanks! I'll give that a shot ---------------------------------------------------------------------------------------------------- [16:06:27] Aaron Quamme(@aquamme):To be clear, I'm trying to do a static build of the gem so it can be included in a SPA. It looks like the examples you linked assume Ruby code is running on the server? ---------------------------------------------------------------------------------------------------- [16:09:58] Elia Schito(@elia):then you should require 'opal-parser', which will parse `

It was made exactly for cases like yours, when you call a method without parentheses and provide a single complex argument wrapped with `()` ---------------------------------------------------------------------------------------------------- [17:36:52] Ilya Bylich(@iliabylich):Time to fix it! :smile: ---------------------------------------------------------------------------------------------------- [17:42:32] Ilya Bylich(@iliabylich):`tLPAREN_ARG`, not `tLBRACE_ARG` ---------------------------------------------------------------------------------------------------- [17:46:13] CJ Lazell(@cj)::D ---------------------------------------------------------------------------------------------------- [18:35:50] Guillaume Grossetie(@Mogztter):Hi ---------------------------------------------------------------------------------------------------- [18:36:44] Guillaume Grossetie(@Mogztter):I'm trying to update from Opal 0.9.0.beta2 to Opal 0.9.2 ---------------------------------------------------------------------------------------------------- [18:38:52] Guillaume Grossetie(@Mogztter):Some Hash methods were renamed: ---------------------------------------------------------------------------------------------------- [18:39:08] Guillaume Grossetie(@Mogztter):```Hash.keys => Hash.$$keys Hash.map => Hash.$$map Hash.smap => Hash.$$smap``` ---------------------------------------------------------------------------------------------------- [18:40:31] Guillaume Grossetie(@Mogztter):Is there an "easy" way to create an alias between old and new name ? ---------------------------------------------------------------------------------------------------- [18:41:21] Guillaume Grossetie(@Mogztter):Yes we do have users that rely heavily on `smap` :cry: ---------------------------------------------------------------------------------------------------- [18:42:12] Guillaume Grossetie(@Mogztter):@fkchang work is in progress, I'm making good progress :wink: ---------------------------------------------------------------------------------------------------- [18:50:08] Ilya Bylich(@iliabylich):@Mogztter it was renamed because `object.property` is an instance variable ---------------------------------------------------------------------------------------------------- [18:50:25] Ilya Bylich(@iliabylich):`$$prop` is an internal Opal property ---------------------------------------------------------------------------------------------------- [19:05:48] Guillaume Grossetie(@Mogztter):I'm sure there's a good reason for this renaming ---------------------------------------------------------------------------------------------------- [19:06:28] Guillaume Grossetie(@Mogztter):but I want to be backward compatible (even if this is a bad practice to use internal property) ---------------------------------------------------------------------------------------------------- [19:07:32] Guillaume Grossetie(@Mogztter):any idea how to achieve this ? ---------------------------------------------------------------------------------------------------- [19:11:02] Ilya Bylich(@iliabylich):@Mogztter No, I think it's impossible ---------------------------------------------------------------------------------------------------- [19:11:27] Ilya Bylich(@iliabylich):You can just use public methods :smile: ---------------------------------------------------------------------------------------------------- [19:22:12] Guillaume Grossetie(@Mogztter):Ok thanks ---------------------------------------------------------------------------------------------------- [22:35:13] Forrest Chang(@fkchang):@wied03 hmm, that's not quite what I saw, but might be related, ```/\s*([A-Z]\w*::(?:[A-Z]+\w*(?:::)?)*)+$/``` acts different in 0.8 and 0.9, in 0.9 it does what I expect, but in 0.8 it's not "greedy enough" if I were to describe it in 2 words ---------------------------------------------------------------------------------------------------- [22:36:35] Forrest Chang(@fkchang):@Mogztter I'd love updates on the progress as well as what you are doing or planning to be doing with it. I suspect server side opal on node could be quite useful in getting opal more widespread ---------------------------------------------------------------------------------------------------- [05:44:18] Forrest Chang(@fkchang):@elia are regex's slightly different in 0.8 and 0.9 ? ---------------------------------------------------------------------------------------------------- [05:53:54] Forrest Chang(@fkchang):apparently they are, upgraded to 0.9 and the regex in question behaves more like I think it should ---------------------------------------------------------------------------------------------------- [06:04:25] Elia Schito(@elia):@fkchang Tbh don't remember :) ---------------------------------------------------------------------------------------------------- [13:08:09] Brady Wied(@wied03):@fkchang - I did make some regex fixes for treating `.` the same in JS as Ruby. ---------------------------------------------------------------------------------------------------- [16:59:50] CJ Lazell(@cj):@elia @iliabylich https://github.com/opal/opal/issues/1428 ---------------------------------------------------------------------------------------------------- [17:20:23] CJ Lazell(@cj):@iliabylich are you around? ---------------------------------------------------------------------------------------------------- [17:21:07] Ilya Bylich(@iliabylich):@cj Yes ---------------------------------------------------------------------------------------------------- ############################## [2016-04-14] ############################## [15:26:05] Brady Wied(@wied03):@iliabylich @elia - You guys know how to keep Opal from adding stubs to non Opal classes/methods? https://gist.github.com/wied03/940e70dcf9da0f3095326e2dfb912381 ---------------------------------------------------------------------------------------------------- [15:27:17] Ilya Bylich(@iliabylich):@weid03 Function is a proc :smile: That's an Opal class ---------------------------------------------------------------------------------------------------- [15:28:05] Brady Wied(@wied03):yep, but any way to be more selective about how we apply it ? ---------------------------------------------------------------------------------------------------- [15:28:25] Brady Wied(@wied03):i have some code that's pure JS that uses `$inject` as a function name and it's getting overwritten ---------------------------------------------------------------------------------------------------- [15:28:52] Brady Wied(@wied03):I suppose I could save off the function before requiring opal and restore it, but was curious if there is a better way ---------------------------------------------------------------------------------------------------- [15:29:17] Brady Wied(@wied03):I don't really want to turn off method_missing entirely either :( ---------------------------------------------------------------------------------------------------- [15:34:32] Ilya Bylich(@iliabylich):Actually don't even know what to say. That's a common problem of conflicting libraries ---------------------------------------------------------------------------------------------------- [15:35:18] Ilya Bylich(@iliabylich):Probably the easiest way here is to save and restore your original function ---------------------------------------------------------------------------------------------------- [15:36:10] Ilya Bylich(@iliabylich):Or you can try to add some code to `Opal.add_stubs` that applies a stub only if it wasn't registered in some global pool of exceptional methods ---------------------------------------------------------------------------------------------------- [15:36:32] Ilya Bylich(@iliabylich):But I'd say it also looks bad :smile: ---------------------------------------------------------------------------------------------------- [15:37:46] Brady Wied(@wied03):exceptional methods. they're so good they can't be stubbed ;) ---------------------------------------------------------------------------------------------------- [15:37:58] Brady Wied(@wied03):so many cheesy puns that can be done there, I'll spare you ---------------------------------------------------------------------------------------------------- [16:03:59] Brady Wied(@wied03):@iliabylich is not even laughing. can't say I blame you. lame jokes. anyways, thanks for being a sounding board ---------------------------------------------------------------------------------------------------- [16:25:21] Ilya Bylich(@iliabylich):@wied03 :+1: ---------------------------------------------------------------------------------------------------- [20:01:17] Elia Schito(@elia):@wied03 you can disable method missing if that's viable ---------------------------------------------------------------------------------------------------- [20:02:32] Elia Schito(@elia):@wied03 is it angular, I remember it used to use properties starting with `$` ---------------------------------------------------------------------------------------------------- [20:04:46] Brady Wied(@wied03):yeah, but that's all or none, and i don't want to do that ---------------------------------------------------------------------------------------------------- [20:05:15] Brady Wied(@wied03):and the opal compiler, which is the code that's "overwriting", relies on method_missing in a few spots I think ---------------------------------------------------------------------------------------------------- [20:06:00] Brady Wied(@wied03):not angular. it's Karma. and since Karma with this webpack loader loads the opal compiler in node, the method gets overwritten ---------------------------------------------------------------------------------------------------- [20:08:25] Brady Wied(@wied03):I might just have to monkey patch `Compiler#method_calls` to exclude `inject` from its list ---------------------------------------------------------------------------------------------------- [20:10:15] Elia Schito(@elia):you can also `var original_add_stubs = Opal.add_stubs; Opal.add_stubs = function(args){/*exclude stuff from args*/; original_add_stubs(args) };` ---------------------------------------------------------------------------------------------------- [20:10:46] Elia Schito(@elia):that patch should go after requiring `corelib/runtime.js` ---------------------------------------------------------------------------------------------------- [20:21:11] Brady Wied(@wied03):that's a good idea ---------------------------------------------------------------------------------------------------- ############################## [2016-04-16] ############################## [01:14:47] Forrest Chang(@fkchang):For anyone interested a react.rb, here's slides from an OCRuby talk I did in January. Thrown together fairly quickly, and w/o all the demos and conversation, but the fact that gitter renders this inline made me want to share it here ---------------------------------------------------------------------------------------------------- [01:14:48] Forrest Chang(@fkchang):http://www.slideshare.net/fkchang/reactrb-all-the-power-of-reactjs-with-all-the-joy-of-ruby ---------------------------------------------------------------------------------------------------- [07:21:13] Barrie Hadfield(@barriehadfield):@fkchang well done, this is an excellent predentation - thank you! ---------------------------------------------------------------------------------------------------- ############################## [2016-04-18] ############################## [20:50:28] Mitch VanDuyn(@catmando):I was just thinking I could block.source -> generate AST -> send 3rd child directly to Opal::CompileAST ---------------------------------------------------------------------------------------------------- [20:51:01] Mitch VanDuyn(@catmando):one less dependency, but as pointed out it depends on the two AST's being compatible. ---------------------------------------------------------------------------------------------------- [20:52:19] Mitch VanDuyn(@catmando):@wied03 -> yeah so I looked at adding AR / reactive-record to opal-factory-girl, and decided it would be both easier and more powerful to simply be able to drive the unit tests directly from the server passing the already built models to the components. ---------------------------------------------------------------------------------------------------- [20:54:33] Mitch VanDuyn(@catmando):the whole mount_component and associated code is less than 200 lines of code. I doubt I could get opal-factory-girl to work with active-record in any where near that (perhaps not.) But in addition it simplifies so much. ---------------------------------------------------------------------------------------------------- [20:59:18] Brady Wied(@wied03):another option is to make the timeout a prop that you can pass down from the server more easily ---------------------------------------------------------------------------------------------------- [20:59:44] Brady Wied(@wied03):i tend to use that instead of constants anyways because it's easier to test from a unit testing standpoint ---------------------------------------------------------------------------------------------------- [20:59:49] Brady Wied(@wied03):but it could help this as well ---------------------------------------------------------------------------------------------------- [21:01:38] Mitch VanDuyn(@catmando):@iliabylich - thanks for the answer BTW... I don't know if you followed all the chatter but I am as you suggest using Opal to just statically compile stuff. I just happen to know that the string I am giving to opal, came from an AST, so rather than turn it back into source, then reparse it, I thought it might be nice to send the AST directly to opal (which I will try fun grins anyway.) ---------------------------------------------------------------------------------------------------- [21:02:26] Mitch VanDuyn(@catmando):@wied03 - a couple of reasons why this want to be a constant. ---------------------------------------------------------------------------------------------------- [21:04:08] Mitch VanDuyn(@catmando):There is an underlying polling loop that updates the UI when chat is availability changes state. Each component is just reflecting the state of that *store*, and so there is only one polling interval. ---------------------------------------------------------------------------------------------------- [21:04:54] Mitch VanDuyn(@catmando):If the chat component was not so small anyway, you could seperate the polling into its own store, and then the mount_component would be just providing an alternative store. ---------------------------------------------------------------------------------------------------- [21:57:03] Elia Schito(@elia):@/all releasing beta3, probably the last beta before a release candidate and a final release ---------------------------------------------------------------------------------------------------- [21:57:44] Elia Schito(@elia):https://twitter.com/rubygems/status/722182273664172033 ---------------------------------------------------------------------------------------------------- [22:35:24] Brady Wied(@wied03):@elia - :+1: - opal-rspec passes fine with beta 3 ---------------------------------------------------------------------------------------------------- [22:58:19] Elia Schito(@elia):@wied03 w00t! :D ---------------------------------------------------------------------------------------------------- [23:33:19] CJ Lazell(@cj):@elia shouldn't Opal.append_path return true? ---------------------------------------------------------------------------------------------------- [17:22:31] Mitch VanDuyn(@catmando):Can I feed ruby AST to the opal compiler? ---------------------------------------------------------------------------------------------------- [17:22:51] Mitch VanDuyn(@catmando):In otherwords I want to do something like this: ---------------------------------------------------------------------------------------------------- [17:23:39] Mitch VanDuyn(@catmando):Opal::CompileAST(Parser::CurrentRuby.parse(some_block.source)) ---------------------------------------------------------------------------------------------------- [17:23:57] Mitch VanDuyn(@catmando):so it will compile existing server code to opal. ---------------------------------------------------------------------------------------------------- [17:25:03] Mitch VanDuyn(@catmando):I am doing this now by just passing some_block.source directly to Opal, but I now want to do some tweaks to the AST before passing to opal, and rather than translate the AST back to source, then back to ruby I thought i would save a step. ---------------------------------------------------------------------------------------------------- [17:25:06] Mitch VanDuyn(@catmando):possible? ---------------------------------------------------------------------------------------------------- [17:54:12] Ilya Bylich(@iliabylich):Opal compiler has a method `process` that takes s expression. You can get this sexp from `Parser#parse` ---------------------------------------------------------------------------------------------------- [17:54:45] Ilya Bylich(@iliabylich):Just don't forget to wrap sexp to `s(:top, parsed_sexp)` ---------------------------------------------------------------------------------------------------- [17:55:02] Ilya Bylich(@iliabylich):(this is what Opal compiler does internally) ---------------------------------------------------------------------------------------------------- [17:58:31] Ilya Bylich(@iliabylich):May I ask you why do you need it? Usually we call `Kernel#eval` for dynamic source code. If your code is static, just require a compiled version. If you code is dynamic - then its AST is also dynamic and you can't partially pre-compile it. Most probably I'm missing something :smile: ---------------------------------------------------------------------------------------------------- [19:31:47] Brady Wied(@wied03):@catmando - I'm wondering the same thing. It also might break fairly easily since the compiler nodes are not necessarily an interface that people avoid changing ---------------------------------------------------------------------------------------------------- [20:26:27] Mitch VanDuyn(@catmando):@wied03 its for my server side test driver. So I can say: ---------------------------------------------------------------------------------------------------- [20:27:52] Mitch VanDuyn(@catmando):```ruby it "will run this test in opal", :opal => true do expect(true).to be_truthy end ``` ---------------------------------------------------------------------------------------------------- [20:28:12] Mitch VanDuyn(@catmando):and the expectation will run in opal-rspec ---------------------------------------------------------------------------------------------------- [20:28:26] Mitch VanDuyn(@catmando): ---------------------------------------------------------------------------------------------------- [20:28:57] Mitch VanDuyn(@catmando): ---------------------------------------------------------------------------------------------------- [20:31:18] Elia Schito(@elia):@rubys came up (years ago?) with a nice trick to compile to opal using the method_source gem, this looks like a very nice application for it ---------------------------------------------------------------------------------------------------- [20:31:57] Elia Schito(@elia):https://rubygems.org/gems/method_source ---------------------------------------------------------------------------------------------------- [20:32:15] Mitch VanDuyn(@catmando):```ruby it "does some fun isomorphic stuff", :js => true do mount_component "Price", job: my_job = FactoryGirl.create(:job, :valid_job) do class Price < React::Component::Base ... modify internal behavior of price for testing end end find(".the-price").text.should eq(my_job.price) end ``` ---------------------------------------------------------------------------------------------------- [20:34:19] Brady Wied(@wied03):@catmando - Don't you really just want to use mocks then (e.g. RSpec mocks) ? ---------------------------------------------------------------------------------------------------- [20:34:47] Mitch VanDuyn(@catmando):@wied03 - I could but we already have the factories set up. ---------------------------------------------------------------------------------------------------- [20:35:05] Brady Wied(@wied03):your example seems to indicate you want to modify the React component (not the factory) ---------------------------------------------------------------------------------------------------- [20:35:19] Mitch VanDuyn(@catmando):kind of a dumb example ---------------------------------------------------------------------------------------------------- [20:36:06] Mitch VanDuyn(@catmando):here is a real one (I think I have given before) ---------------------------------------------------------------------------------------------------- [20:36:08] Brady Wied(@wied03):i do RSpec tests all the time that I run on both sides and I just surround some of my `describe` calls, etc. with RUBY_ENGINE guards ---------------------------------------------------------------------------------------------------- [20:37:42] Mitch VanDuyn(@catmando):```ruby require 'spec_helper' describe 'chat component', :js => true, group: 2 do before(:each) do @agents_online = 0 stub_request(:get, "support.catprint.com/customer/agent_online_check"). to_return { {body: "{\"online_agents\":#{@agents_online},\"routing_agents\":#{@agents_online}}"} } FactoryGirl.create :production_center, domain: "127.0.0.1", code: "US" end it "switches from offline to online" do mount("Chat", online_text: "ONLINE", offline_text: "OFFLINE") do class Components::Chat < React::Component::Base POLL_INTERVAL = 1 # override default of 5 minutes end end page.should have_content('OFFLINE') wait_for_ajax @agents_online = 2 Rails.cache.delete('desk_agents_online') page.should have_content('ONLINE') end ``` ---------------------------------------------------------------------------------------------------- [20:39:00] Brady Wied(@wied03):@catmando - Much easier to do with unit tests in JS. beating a dead horse? ;) ---------------------------------------------------------------------------------------------------- [20:39:19] Brady Wied(@wied03):Anyways, why not do what they said earlier and use `eval` ? ---------------------------------------------------------------------------------------------------- [20:40:39] Mitch VanDuyn(@catmando):@wied03 - I would very much like to see how this could be done easier than the above... ---------------------------------------------------------------------------------------------------- [20:40:53] Brady Wied(@wied03):what about eval ? ---------------------------------------------------------------------------------------------------- [20:41:18] Brady Wied(@wied03):If you humor my unit test stuff though, that's much easier. You just monkey patch or mock that poll interval and you're done ---------------------------------------------------------------------------------------------------- [20:41:34] Brady Wied(@wied03):because your tests are ruby/opal code running alongside the react component ---------------------------------------------------------------------------------------------------- [20:41:42] Mitch VanDuyn(@catmando):not quite - that component needs the production_center to work ---------------------------------------------------------------------------------------------------- [20:42:31] Brady Wied(@wied03):you could use factory girl on the opal side to avoid re-doing the work of constructing a production_center ---------------------------------------------------------------------------------------------------- [20:42:46] Brady Wied(@wied03):or some support code that builds one manually ---------------------------------------------------------------------------------------------------- [20:43:22] Mitch VanDuyn(@catmando):@wied03 - and so we come full circle. You might remember our first conversation was about getting factory-girl opal to work with active-record ---------------------------------------------------------------------------------------------------- [20:43:36] Elia Schito(@elia):@catmando I think method_source is a viable option to collect the block source code, compile and run it with opal ---------------------------------------------------------------------------------------------------- [20:44:56] Brady Wied(@wied03):@catmando - Sounds like what @elia is mentioning + eval could help. seems like a lot of work just to test this though ---------------------------------------------------------------------------------------------------- [20:46:01] Mitch VanDuyn(@catmando):RE: eval... that is essentially what I am doing now... however the problem is if you have code like this: ```ruby mount_component "Foo" do puts "hello" end ``` the block.source for the do, includes the line "mount_component" which we don't want so I just use the AST tree to get the actual block ---------------------------------------------------------------------------------------------------- [20:46:52] Brady Wied(@wied03):what if you did `def mount_component; yield; end` somewhere else that wasn't dynamic ---------------------------------------------------------------------------------------------------- [20:47:13] Brady Wied(@wied03):inject it (compiled via opal) in some place before the other stuff runs ---------------------------------------------------------------------------------------------------- [20:47:30] Brady Wied(@wied03):or more like instance_eval(&block) but you get the idea ---------------------------------------------------------------------------------------------------- [20:47:45] Brady Wied(@wied03):then you'd avoid coupling to compiler nodes ---------------------------------------------------------------------------------------------------- [20:48:10] Brady Wied(@wied03):@catmando - as to AR. I have no problem with a PR for opal-factory-girl to work with the AR stuff as long as it doesn't require a bunch of additional stuff in there. ---------------------------------------------------------------------------------------------------- [20:49:36] Mitch VanDuyn(@catmando):@wied03 - at any rate this is all working today (and has been for sometime) I was just thinking it might be nice to git rid of the extra step. Right now it works like this block.source -> generate AST -> convert 3rd child back to source -> send to Opal to compile. ---------------------------------------------------------------------------------------------------- ############################## [2016-04-19] ############################## [00:08:41] Elia Schito(@elia):@cj no, the return value is not guaranteed to be anything particular ---------------------------------------------------------------------------------------------------- ############################## [2016-04-21] ############################## [16:12:25] Forrest Chang(@fkchang): I wanna pimp @elia 's talk from wrocloverb -- Thought it was a good intro overview of what opal is and why Rubyists should try it (still shocked at how largely unknown it is to the Ruby community at large), I liked the slides themselves quite a bit https://www.youtube.com/watch?v=vhIrrlcWphU ---------------------------------------------------------------------------------------------------- [17:28:38] George Plymale II(@ylluminarious):@elia nice talk! your tetris port was really interesting; reminds me of [things](https://github.com/ylluminarious/opal_pong) [that](https://github.com/ylluminarious/js_pong) [i've](https://github.com/orbitalimpact/flutterjump) [done](https://github.com/orbitalimpact/opal-phaser-examples) with opal games and ports. i have to say, developing games with opal is a pretty fun process :D ---------------------------------------------------------------------------------------------------- [17:30:45] Elia Schito(@elia):@ylluminarious you should write about that! send them to peter cooper for rubyweekly and stuff! ---------------------------------------------------------------------------------------------------- [17:31:16] Elia Schito(@elia):@fkchang hey thanks! didn't know the video was up untill now! :D ---------------------------------------------------------------------------------------------------- [17:31:34] George Plymale II(@ylluminarious):@elia not a bad idea, thanks for the tip :) ---------------------------------------------------------------------------------------------------- ############################## [2016-04-22] ############################## [00:24:57] Brady Wied(@wied03):@elia @catmando - You guys might find this useful - https://github.com/wied03/opal-require-dep ---------------------------------------------------------------------------------------------------- [01:11:37] Mitch VanDuyn(@catmando):@wied03 - I kid you not...

I’ve got a Trailblazer application and I translated an infinite-scroll.coffee into an opal class but I can’t get opal-rspec to work so testing it is still a noop for me. Thoughts? ---------------------------------------------------------------------------------------------------- [21:44:05] Brady Wied(@wied03):Sure. can you be more specific about what's not working ? ---------------------------------------------------------------------------------------------------- [21:45:19] Brady Wied(@wied03):@erlandsona ---------------------------------------------------------------------------------------------------- [21:50:44] Austin Erlandson(@erlandsona):Absolutely, I’ve got opal-rails in the gem file added the configs from the opal-rails README Followed the setup for a “legacy rails app” from here… http://rubyist.jaredwhite.com/2015/07/22/how-to-introduce-opal-gently-into-a-legacy-rails-app/ And I rewrote / debugged a handrolled jQuery infinite-scroll in Opal which was such a refreshing experience, BTW! Next step was to get some specs running so I could test the InfiniteScroll class I’d just sparked. But first thing I ran into was where do I put the _spec.opal file… Then once I as able to get the browser route /opal_spec working at this point I noticed in the console it showed that Opal was not defined for the spec file. I added a require to the file and then describe was an undefined method so I added `require ‘opal-rspec’` and the console errors went away but the specs still aren’t executing. I’ve tried both opal-rails with opal 0.8 and opal 0.9+ and I much prefer the spec runner template for 0.9+ obviously but specs still aren’t executing… ---------------------------------------------------------------------------------------------------- [22:01:14] Austin Erlandson(@erlandsona):```ruby # require 'opal' # require 'opal-rspec' describe 'a spec' do it 'has successful examples' do expect('I run').to =~ /run/ end end ``` ---------------------------------------------------------------------------------------------------- [22:04:50] Brady Wied(@wied03):hmm. I'm an opal-rspec maintainer, but I don't use opal-rails but I'll take a quick look. You're using opal-rspec-rails, right ? ---------------------------------------------------------------------------------------------------- [22:06:52] Brady Wied(@wied03):opal-rails is now meant to be test framework agnostic, but I guess from looking further that @elia hasn't released opal-rspec-rails yet ---------------------------------------------------------------------------------------------------- [22:09:15] Brady Wied(@wied03):spec-opal is where he puts them in the 0.8.1 opal-rails test app ---------------------------------------------------------------------------------------------------- [22:10:11] Austin Erlandson(@erlandsona):So I’ve tried both the opal 0.8 implementation of opal-rails and the opal 0.9+ implementation of opal-rails with the extra opal-rspec-rails gem and in both cases I can get to the browser spec template… the whole /opal_spec (0.8) or /spec-opal (0.9) and it shows the spec file I want it to run but it doesn’t actually run any specs… My main thought is that I must not have phantomjs setup properly? My assumption is that phantom comes pre built into the spec gem but I also did an `npm install -g phantomjs` just to be safe… I also found the opal-rspec documentation about how to run the specs with a rake task but not sure about where in my stack that code should go. ---------------------------------------------------------------------------------------------------- [22:11:27] Austin Erlandson(@erlandsona):I’m happy to screenshare if it would help? I’m in Nashville, TN. ---------------------------------------------------------------------------------------------------- [22:12:26] Brady Wied(@wied03):Phantom is not bundled in there, that's separate. I'm trying to get up to speed. elia is out of town this weekend as well ---------------------------------------------------------------------------------------------------- [22:12:50] Brady Wied(@wied03):but when you hit that browser page, the browser is what should run them, not phantom ---------------------------------------------------------------------------------------------------- [22:15:14] Brady Wied(@wied03):I think I know what might be missing from the docs ---------------------------------------------------------------------------------------------------- [22:15:41] Austin Erlandson(@erlandsona):Hmmm… yeah that’s what I was thinking too. I thought it was odd that the Opal object wasn’t available to the spec file. I’ve also moved the spec file to a number of different directory locations. I’ve tried putting it in the following locations… app/assets/javascripts/spec/browser_spec.opal spec/solutions/search/browser_spec.opal spec/browser_spec.opal etc... ---------------------------------------------------------------------------------------------------- [22:17:55] Brady Wied(@wied03):opal-rails uses a different mechanism to run than core opal-rspec does, but I think the approach he was leaning towards with opal-rails is that you'd need to do something like this in your spec_helper ---------------------------------------------------------------------------------------------------- [22:17:56] Brady Wied(@wied03):```ruby ---------------------------------------------------------------------------------------------------- [22:18:08] Brady Wied(@wied03):```ruby at_exit { RSpec::Core::Runner.autorun } ``` ---------------------------------------------------------------------------------------------------- [22:18:56] Brady Wied(@wied03):I can't say for sure what direction he's going with opal-rails, but you might want to do that because it sounds like your opal-rails install scans your app for spec files but the thing to make RSpec actually run isn't present in your code (or opal-rails 0.8.1 code) ---------------------------------------------------------------------------------------------------- [22:19:38] Brady Wied(@wied03):As to opal itself, latest is always best, so I'd recommend Opal 0.9.2 (should work fine with opal-rails, including 0.8.1) ---------------------------------------------------------------------------------------------------- [22:22:27] Austin Erlandson(@erlandsona):Yeah just installed 0.9.2 again, I’ve been switching back and forth between them wondering if either was a more stable version that might just work out of the box but no luck with either. Regardless gitter has completely changed my life in Open Source being able to communicate with the authors of this code that I use on a daily basis is so powerful! Anyways, So something like… ```ruby require 'rubygems' require 'simplecov' SimpleCov.start 'rails' ENV['RAILS_ENV'] = 'test' ENV['CLOUDINARY_CLOUD_NAME'] = 'test' ENV['VERSION_TOKEN'] = 'test_version_token' require File.expand_path("../../config/environment", __FILE__) require 'avocado/rspec' require 'rspec/rails' WebMock.disable_net_connect! allow: [ ENV['ELASTICSEARCH_URL'] ], allow_localhost: true ActiveRecord::Migration.maintain_test_schema! # Requires supporting ruby files with custom matchers and macros, etc, # in spec/support/ and its subdirectories. Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f } RSpec.configure do |config| config.order = :random config.use_transactional_fixtures = true config.infer_base_class_for_anonymous_controllers = false config.infer_spec_type_from_file_location! config.render_views = true config.global_fixtures = :all config.fixture_path = Rails.root.join('spec', 'fixtures') config.include Capybara::DSL config.include Devise::TestHelpers, type: :controller config.include ActiveJob::TestHelper config.include Warden::Test::Helpers config.before :suite do Warden.test_mode! end Shoulda::Matchers.configure do |config| config.integrate do |with| with.test_framework :rspec with.library :rails end end # Blacklist any HTTP calls that might be made during JS tests, such # as hard-coded image URLs, Google fonts, etc Capybara::Webkit.configure do |config| config.block_unknown_urls end # config.before :each, js: true do # page.driver.browser.url_blacklist = %w() # end # config.expect_with :rspec do |expectations| expectations.include_chain_clauses_in_custom_matcher_descriptions = true expectations.syntax = :expect end config.mock_with :rspec do |mocks| mocks.verify_partial_doubles = true mocks.syntax = :expect end end at_exit { RSpec::Core::Runner.autorun } ``` The key line being ^ ---------------------------------------------------------------------------------------------------- [22:22:29] Brady Wied(@wied03):the test app @ https://github.com/opal/opal-rails/blob/v0.8.1/test_app/spec-opal/spec_helper.rb has some code like that, but unless you can guarantee the autorun statement runs last after opal-rails 'requires' all of your specs, then you'll miss some, thus I think you need that ---------------------------------------------------------------------------------------------------- [22:23:23] Brady Wied(@wied03):Yes, except you need a separate spec_helper in the `spec_opal` directory where you put your tests. you can't/shouldn't use the same one that you have in `spec` for your typical MRI based tests ---------------------------------------------------------------------------------------------------- [22:25:01] Brady Wied(@wied03):How RSpec works (which is different that say test-unit) but similar to Mocha or Jasmine is that requiring the specs (which I think opal-rails does for you and opal-rspec's standalone stuff also does) just tells RSpec about which tests (examples) and example groups you have. It doesn't run them though until it sees that 1 line. ---------------------------------------------------------------------------------------------------- [22:26:39] Brady Wied(@wied03):If some of this could be easier, feel free to document some of it in a github issue on the opal-rails project. Some of this might be that elia is a busy guy and he hasn't got a chance to release his current opal-rails/opal-rspec-rails work that make this clearer ---------------------------------------------------------------------------------------------------- [22:28:54] Austin Erlandson(@erlandsona):Just tried it out… I’ve currently got my browser_spec.opal file under app/concepts/solutions/search/browser.opal app/concepts/solutions/search/browser_spec.opal And in my config/application.rb I set the `config.opal.spec_location = “app/concepts”` ---------------------------------------------------------------------------------------------------- [22:29:15] Austin Erlandson(@erlandsona):Here’s what I’ve got… ---------------------------------------------------------------------------------------------------- [22:29:20] Austin Erlandson(@erlandsona):[![Screen Shot 2016-04-23 at 5.26.56 PM.png](https://files.gitter.im/opal/opal/Dg89/thumb/Screen-Shot-2016-04-23-at-5.26.56-PM.png)](https://files.gitter.im/opal/opal/Dg89/Screen-Shot-2016-04-23-at-5.26.56-PM.png) ---------------------------------------------------------------------------------------------------- [22:31:45] Austin Erlandson(@erlandsona):Ideally I’d eventually like to put my tests in the same directory as my source given that most of the code I’m writing at this point is all component based. EG: Trailblazer, and eventually probably React.rb. Not sure how to get there though. ---------------------------------------------------------------------------------------------------- [22:33:34] Brady Wied(@wied03):I'm not sure why you'd want tests in the same dir as the source, but that's another conversation ---------------------------------------------------------------------------------------------------- [22:33:56] Brady Wied(@wied03)::) ---------------------------------------------------------------------------------------------------- [22:33:57] Brady Wied(@wied03):I never use the Opal suffix, I use _spec.rb as the suffix, not sure if that is the issue or not ---------------------------------------------------------------------------------------------------- [22:36:00] Brady Wied(@wied03):that should work though (after looking @ the code) ---------------------------------------------------------------------------------------------------- [22:37:06] Brady Wied(@wied03):are you requiring a spec_helper.opal file that's located inside app/concepts from within browser_spec.opal ? ---------------------------------------------------------------------------------------------------- [22:37:20] Brady Wied(@wied03):name is immaterial, is long as you require it and it has the at_exit code above in it ---------------------------------------------------------------------------------------------------- [22:37:49] Brady Wied(@wied03):might want to check your browser's console as well and see what errors are showing up there if any ---------------------------------------------------------------------------------------------------- [22:38:34] Austin Erlandson(@erlandsona):Component based file organization, helps me to keep the business domain and isolate dependencies, enabling faster and more stable refactoring of code. When it’s all in different directories based on file type it can be hard to keep in your head which code touches which parts of the app. It’s also a best practice in most front-end frameworks at this point. RE: http://www.johnpapa.net/angular-app-structuring-guidelines/ Oh and you mean requiring the spec_helper from the manifest file right?! How could I forget! Freaking dependencies man! I love it! ---------------------------------------------------------------------------------------------------- [22:39:14] Brady Wied(@wied03):I'm not sure what you mean by manifest file ---------------------------------------------------------------------------------------------------- [22:39:33] Brady Wied(@wied03):I think that's an Angular habit I'm happy to not adopt ---------------------------------------------------------------------------------------------------- [22:40:01] Brady Wied(@wied03):habit/practice ---------------------------------------------------------------------------------------------------- [22:41:04] Brady Wied(@wied03):I do agree that separation of concerns is a problem in the Rails world. I usually would go a different route to achieve that. ---------------------------------------------------------------------------------------------------- [22:42:04] Austin Erlandson(@erlandsona):It’s actually a React concept that Angular adopted and now being adopted by more and more frameworks like Ember in their V2’s… Added the require to app/concepts/browser_manifest.opal ---------------------------------------------------------------------------------------------------- [22:45:21] Austin Erlandson(@erlandsona):Here’s my dependency tree to make opal work with the current setup it’s a bit to follow but here goes… app/assets/javascripts/app_js_manifest.js ```javascript //= require jquery.smartWizard //= require lodash //= require slick //= require survey-responses //= require selectize //= require login/email-matcher //= require login/organizations-input //= require javascripts //= require project_boards ``` app/assets/javascripts/application.opal ```ruby require 'jquery' require 'jquery_ujs' require 'opal' require 'opal_ujs' # 0.9.2 is required # require 'console' require 'app_js_manifest' require 'browser_manifest' ``` app/concepts/browser_manifest.opal ```ruby require 'spec_helper' require 'solutions/search/browser' ``` Here’s the actual opal source for the infinite scroll app/concepts/solutions/search/browser.opal ```ruby module Solutions module Search class InfiniteScroll def initialize(elem, pixels = 400) @scrollable_element = elem @loading_next_page = false @pixels_from_bottom = pixels # pixels above the bottom @page = 2 @image = Element.parse "

I think separating specs from app is okay but not really because I just end up duplicating the component structure anyways. It would just be really nice to have everything I need for a feature, from the controller, the viewmodel, the services, template, styles, poro’s whatever all in one directory per feature. ---------------------------------------------------------------------------------------------------- [22:54:16] Brady Wied(@wied03):Understandable ---------------------------------------------------------------------------------------------------- [22:54:39] Austin Erlandson(@erlandsona):Alright moved everything into browser_spec/browser_spec.opal still no execution? ---------------------------------------------------------------------------------------------------- [22:55:04] Brady Wied(@wied03):did you look at your browser console (See above) ? ---------------------------------------------------------------------------------------------------- [22:55:43] Austin Erlandson(@erlandsona):Yeah only thing I’m getting is a warning stating … Object freezing is not supported by Opal ---------------------------------------------------------------------------------------------------- [22:56:43] Austin Erlandson(@erlandsona):Are you available to do a quick hangout by any chance? ---------------------------------------------------------------------------------------------------- [22:58:59] Brady Wied(@wied03):not right now ---------------------------------------------------------------------------------------------------- [22:59:14] Austin Erlandson(@erlandsona):No biggie ---------------------------------------------------------------------------------------------------- [22:59:21] Brady Wied(@wied03):can you put a "puts 'hello 123'" in your at_exit block and see if you see that ---------------------------------------------------------------------------------------------------- [23:00:18] Austin Erlandson(@erlandsona):… ---------------------------------------------------------------------------------------------------- [23:02:12] Austin Erlandson(@erlandsona):Nope still a no op… ---------------------------------------------------------------------------------------------------- [23:06:10] Brady Wied(@wied03):you're checking the browser console ? ---------------------------------------------------------------------------------------------------- [23:06:16] Austin Erlandson(@erlandsona):Yup. ---------------------------------------------------------------------------------------------------- [23:06:36] Brady Wied(@wied03):what about putting the puts statement outside the at_exit block ---------------------------------------------------------------------------------------------------- [23:09:46] Austin Erlandson(@erlandsona):Still nothing… which means the spec_helper isn’t being required anywhere. So I’ve got config/application.rb with ```ruby ############### # Opal configs. ######### # Compiler options config.opal.method_missing = true config.opal.optimized_operators = true config.opal.arity_check = false config.opal.const_missing = true config.opal.dynamic_require_severity = :ignore # Enable/disable /opal_specs route config.opal.enable_specs = true # The path to opal specs from Rails.root config.opal.spec_location = 'browser_spec' ``` I have spec_browser/browser_spec.opal with the spec. spec_browser/spec_helper.opal with ```ruby require 'opal' require 'opal-rspec' puts 'hello 123' at_exit do Opal::RSpec::Runner.autorun end ``` ---------------------------------------------------------------------------------------------------- [23:11:52] Austin Erlandson(@erlandsona):I also tried `require`ing the spec_helper from my app/assets/javascripts/application.opal file which also didn’t work :/ ---------------------------------------------------------------------------------------------------- [23:15:45] Brady Wied(@wied03):Honestly I'm not sure what it is. It's been months since I even looked at opal-rails. The opal community probably owes you a better answer than that thoguh ---------------------------------------------------------------------------------------------------- [23:15:46] Brady Wied(@wied03):though ---------------------------------------------------------------------------------------------------- [23:17:13] Austin Erlandson(@erlandsona):Haha. No biggie I also tried a simple rails new —javascripts=opal to see if I could get specs working on a sample project and same story… Do you have a working example with specs I could check out somewhere? ---------------------------------------------------------------------------------------------------- [23:17:16] Brady Wied(@wied03):@fkchang - You know what the issue might be ? ---------------------------------------------------------------------------------------------------- [23:18:51] Brady Wied(@wied03):@erlandsona - I use opal-rspec all the time and I use with Rails, just not with opal-rails specifically. If you look at the opal-rspec source, you'll see a Rake task that invokes a bunch of specs in 'spec/opal' ---------------------------------------------------------------------------------------------------- [23:20:39] Austin Erlandson(@erlandsona):Yeah I looked at the opal-rspec source and figured opal-rails was somehow doing a lot of this configuration. But it may just not be very flexible currently? I’m cool with setting up opal-rspec myself just not sure where to put the rake task in my setup? ---------------------------------------------------------------------------------------------------- [23:21:01] Brady Wied(@wied03):That's not a Rails app of course. If you like using Karma, there is a Rails integration test here https://github.com/wied03/karma-opal-rspec/tree/master/spec/integration/rails_case ---------------------------------------------------------------------------------------------------- [23:22:44] Brady Wied(@wied03):In that case, Karma auto requires opal and opal-rspec and handles the test running for you. If you want to run opal-rspec standalone, you can have an opal initializer file similar to what's in that Opal test case, then just declare a task in lib/whatever.task in your Rails app like this: ```ruby Opal::RSpec::RakeTask.new('opal:spec_in_env' => :environment) do |server, task| app = Rails.application task.files = FileList[ app.root.join('spec/javascripts/**/*_spec{,.js}.{rb,opal}'), app.root.join('spec/shared/**/*_spec{,.js}.{rb,opal}') ] task.default_path = 'spec/javascripts' app.assets.paths.each { |p| server.append_path p } %w(spec/javascripts spec/shared).each { |p| server.append_path p } end ``` ---------------------------------------------------------------------------------------------------- [23:23:48] Brady Wied(@wied03):There's nothing special about Rails there except for the dependency on environment and the fact that it adds Rails' sprockets load paths to the Opal Rake Task with the `app.assets` line ---------------------------------------------------------------------------------------------------- [23:25:15] Austin Erlandson(@erlandsona):Hmm… nice! Yeah so that part is the part I’m a bit timid about… Mainly just because I’m not as familiar with Sprockets as I should be, Grunt, Gulp, Brunch, I can configure to do my bidding but haven’t had the week or two I’d need to really dig into tinkering with the sprockets source / config to really understand how it works. ---------------------------------------------------------------------------------------------------- [23:25:45] Brady Wied(@wied03):And you don't have to require opal or opal-rspec in your specs/spec helper when you use its Rack helper (see the opal rspec homepage) or the Rake task ---------------------------------------------------------------------------------------------------- [23:26:10] Brady Wied(@wied03):And it's not an official Opal project, but some of us are tinkering around with this if you like webpack: https://github.com/cj/opal-webpack ---------------------------------------------------------------------------------------------------- [23:26:40] Brady Wied(@wied03):the latest (under dev) version of karma-opal-rspec uses that instead of Sprockets ---------------------------------------------------------------------------------------------------- [23:27:33] Austin Erlandson(@erlandsona):I’m drooling. Unfortunately I also haven’t had the week or two to dig into Webpack. :/ This is where I’d need a walkthrough or something. ---------------------------------------------------------------------------------------------------- ############################## [2016-04-25] ############################## [16:10:04] Forrest Chang(@fkchang):@erlandsona I'll see if I can duplicate ---------------------------------------------------------------------------------------------------- [16:10:27] Forrest Chang(@fkchang):but I think @elia is the real source of knowledge on this ---------------------------------------------------------------------------------------------------- [16:11:41] Austin Erlandson(@erlandsona):Thanks a ton @fkchang! If I do need to get ahold of @elia what's the best time ? ---------------------------------------------------------------------------------------------------- [16:13:20] Forrest Chang(@fkchang):@erlandsona do you have a preferred target opal and rails versions? I'll try from scratch ---------------------------------------------------------------------------------------------------- [16:14:06] Brady Wied(@wied03):@erlandsona - elia will be back in a couple days. I think he's aware of what you're asking about. It's a busy time for him with the upcoming Opal 0.10 release. ---------------------------------------------------------------------------------------------------- [16:14:14] Forrest Chang(@fkchang):I think @elia would normally be on right now, but he's normally on Italy time, but I dunno if he's elsewhere @wied03 mentioned something of him not being around for the weekend ---------------------------------------------------------------------------------------------------- [16:14:26] Austin Erlandson(@erlandsona):Ruby 2.2.0 ---------------------------------------------------------------------------------------------------- [16:14:43] Austin Erlandson(@erlandsona):Rails ~> 4.2 ---------------------------------------------------------------------------------------------------- [16:14:55] Austin Erlandson(@erlandsona):Opal ~> 9.2 ---------------------------------------------------------------------------------------------------- [18:11:53] Forrest Chang(@fkchang):@erlandsona take a look at https://github.com/fkchang/opal-rails-rspec-test ---------------------------------------------------------------------------------------------------- [18:13:37] Forrest Chang(@fkchang):I realize as I commit this, it's using opal 0.8.1 - sorry, I haven't really used 0.9 yet, so I imagine there might be some differences.

Anybody could help? ---------------------------------------------------------------------------------------------------- [20:33:47] Forrest Chang(@fkchang):@zsolt-rozsnyai I don't believe rails 5 support is ready yet. My last collection is that @elia is still working on it. Anyone else know any different? ---------------------------------------------------------------------------------------------------- [20:36:25] Brady Wied(@wied03):I believe elia was working on the new sprockets version which is the main issue there ---------------------------------------------------------------------------------------------------- [20:57:02] Zsolt Rozsnyai(@zsolt-rozsnyai):thank you for the replies, I check if I can patch it ---------------------------------------------------------------------------------------------------- ############################## [2016-04-26] ############################## [14:57:02] Elia Schito(@elia):@zsolt-rozsnyai yes, there's a sprockets-4 branch on opal/opal ---------------------------------------------------------------------------------------------------- [14:57:08] Elia Schito(@elia):still WIP tho ---------------------------------------------------------------------------------------------------- [20:48:28] Zsolt Rozsnyai(@zsolt-rozsnyai):@elia there is no sprockets-4 branch on opal/opal, maybe you haven't pushed it.

I can’t figure out how to get the specs set up in my project though… Are you available to help? I’ve been working through @fkchang ’s example. Is there a way to configure opal-rspec to run the specs located inside an app/concepts/feature directory? I’m using Trailblazer to organize the backend into a component based architecture and it would be really nice if I could get all the specs inside the feature directories as well. ---------------------------------------------------------------------------------------------------- ############################## [2016-04-29] ############################## [00:28:38] Austin Erlandson(@erlandsona):Nvmnd! I got it! I just had to add config.opal_spec.spec_location and modify the opal-rspec-rails gem locally so that I could use the .opal naming convention which is important if I want to eventually put regular rspec’s in the same directory as well… eg: feature/controller_spec.rb vs feature/browser_spec.opal I would want the opal runner to run opal specs for now and rspec to run regular specs. ---------------------------------------------------------------------------------------------------- [00:30:18] Austin Erlandson(@erlandsona):@fkchang ^ Yay! ---------------------------------------------------------------------------------------------------- [00:54:22] Austin Erlandson(@erlandsona):Well sort of… I got a single spec to run but I’m trying to get some actual tests to run and I can’t instantiate the object I’m trying to test… :/ ---------------------------------------------------------------------------------------------------- [08:26:56] Elia Schito(@elia):@erlandsona I'm not really familiar with trailblazer, having some example code to look at would make it easier ---------------------------------------------------------------------------------------------------- [09:23:27] Barrie Hadfield(@barriehadfield):@erlandsona have a look at http://reactrb.org/ as react components map very nicely to TRB cells (conceptually as view models). I am also using TRB concepts for the back end and have replaced my entire UI from Cells to React components using react.rb and I am never looking back! ---------------------------------------------------------------------------------------------------- [13:07:51] Austin Erlandson(@erlandsona):@barriehadfield do you have an example app with TRB and React.rb I could look at? I'm dying to try out React.rb but I can't seem to get the ecosystem set up. Is React.rb pretty easy to write opal-rspecs for? ---------------------------------------------------------------------------------------------------- [14:12:16] Brady Wied(@wied03): @erlandsona - It's not hard to write RSpec tests for React components. I have 500 of them. To my knowledge, there isn't a shared approach yet but it's not hard using the wrappers react.rb already has for React test utils ---------------------------------------------------------------------------------------------------- [14:12:35] Brady Wied(@wied03):it can be trickier if you use a lot of stateful components (as opposed to the Redux/Grand Central way) ---------------------------------------------------------------------------------------------------- [14:14:27] Brady Wied(@wied03):@erlandsona - example - https://gist.github.com/wied03/a6b198a6d8820e8328037183e7b5c6f1 ---------------------------------------------------------------------------------------------------- [14:18:58] Barrie Hadfield(@barriehadfield):@erlandsona I will publish a sample app over the weekend for you. It did take some time to get the echosystem all working but I have eventually settled on using a combination of some gems (with Sprockets) and most of the front end assets beling delivered by Webpack. I would love to get 100% Webpack for the FE and am eagerly watching Opal progress here. ---------------------------------------------------------------------------------------------------- [14:20:39] Brady Wied(@wied03):@barriehadfield - https://github.com/cj/opal-webpack ---------------------------------------------------------------------------------------------------- [14:22:52] Barrie Hadfield(@barriehadfield):yes, I am very excited about that. I have not tried it yet and wondered if it would play nicely with the react.rb approach? ---------------------------------------------------------------------------------------------------- [14:24:01] Brady Wied(@wied03):I can't speak to Reactive record and all that stuff, but the core React.rb should work fine ---------------------------------------------------------------------------------------------------- [14:25:13] Barrie Hadfield(@barriehadfield):would there be any special considerations? (I had been thinking I would have to remove the react.rb gem and go 100% webpack). ---------------------------------------------------------------------------------------------------- [14:27:24] Brady Wied(@wied03):no. if you did that, you'd have to write React components the JS way ---------------------------------------------------------------------------------------------------- [14:27:50] Brady Wied(@wied03):React.rb GEM and opal webpack do not do the same thing. Webpack, if you use it a runtime, is more of a replacement for sprockets than it is React.rb ---------------------------------------------------------------------------------------------------- [14:28:09] Brady Wied(@wied03):I only use it to run tests with Karma right now ---------------------------------------------------------------------------------------------------- [14:28:10] Barrie Hadfield(@barriehadfield):excellent news ---------------------------------------------------------------------------------------------------- [14:51:16] Austin Erlandson(@erlandsona):@barriehadfield are you available to do like a hangout and take a look at the system by any chance? ---------------------------------------------------------------------------------------------------- [14:57:50] Barrie Hadfield(@barriehadfield):@erlandsona sure - happy to do that. message me privatly and we can set it up ---------------------------------------------------------------------------------------------------- [16:21:41] Austin Erlandson(@erlandsona):So @barriehadfield and I were not able to get the specs to run… anyone else want to jump on a hangout with me and try to figure it out? @wied03 I’m super close just can’t quite get the spec to recognize the file I’m trying to test and I’ve tried requiring but no luck... ---------------------------------------------------------------------------------------------------- [16:25:00] Austin Erlandson(@erlandsona):I’ve got `config.opal_spec.spec_location = 'app/concepts’` in config/application.rb I bundle opened opal-rspec-rails and patched the opal/opal-rspec-rails-runner.rb.erb file to recognize `**/*_spec.opal` instead of `**/*_spec.rb` files… which works well. And that config works without a spec_helper. But this is the part where I think I need a spec_helper to load all the opal source so I can test it from my _spec.opal files as currently the classes I have defined in my source files are not available in the _spec scope. Thoughts? ---------------------------------------------------------------------------------------------------- [16:31:06] Brady Wied(@wied03):@erlandsona - you have to `require` what you're testing from your specs no matter what. that's true for anything outside of Rails autoload ---------------------------------------------------------------------------------------------------- [16:31:25] Brady Wied(@wied03):now if that doesn't throw a sprockets error, then sprockets is including your impl ---------------------------------------------------------------------------------------------------- [16:31:41] Austin Erlandson(@erlandsona):yeah I’m getting the sprockets error page when I add the `require ‘infinite_scroll’` at the top of the infinite_scroll_spec.opal file ---------------------------------------------------------------------------------------------------- [16:36:34] Brady Wied(@wied03):is infinite_scroll in your Opal load path ? ---------------------------------------------------------------------------------------------------- [16:38:18] Austin Erlandson(@erlandsona):Not exactly sure how to answer that. The code for the infinite scroll works EG: the page infinitely scrolls and there’s no JS that would make that happen… But it may not be in the load path for the specs… Stupid question but how do I determine the load path? ---------------------------------------------------------------------------------------------------- [16:38:21] Brady Wied(@wied03):```ruby # config/initializers/opal.rb Rails.application.config.assets.paths << Rails.root.join('app', 'views', 'shared').to_s ``` ---------------------------------------------------------------------------------------------------- [16:38:39] Brady Wied(@wied03):you would need to have something like that ---------------------------------------------------------------------------------------------------- [16:38:46] Brady Wied(@wied03):this is from the opal-rails site ---------------------------------------------------------------------------------------------------- [16:39:24] Brady Wied(@wied03):in opal-rails case, the Opal load paths all end up in sprockets' load path, which is what Rails.application.config.assets.paths is ---------------------------------------------------------------------------------------------------- [16:39:47] Brady Wied(@wied03):one of the directories in that load path needs to contain 'infinite_scroll' for this to work ---------------------------------------------------------------------------------------------------- [16:40:16] Austin Erlandson(@erlandsona):It should… Let me double check though... ---------------------------------------------------------------------------------------------------- [16:40:29] Brady Wied(@wied03):and it can't be in a subdirectory or what not unless that subdirectory is in your load path or you require it differently than you are ---------------------------------------------------------------------------------------------------- [16:41:02] Brady Wied(@wied03):this may be working differently at runtime if you're using sprockets //=require stuff and relative stuff in something like application.js ---------------------------------------------------------------------------------------------------- [16:41:16] Austin Erlandson(@erlandsona):I’m assuming you don’t have a second to screenshare? ---------------------------------------------------------------------------------------------------- [16:42:39] Brady Wied(@wied03):correct, i'm working :( ---------------------------------------------------------------------------------------------------- [16:43:07] Brady Wied(@wied03):I could look without audio though ---------------------------------------------------------------------------------------------------- [16:43:25] Austin Erlandson(@erlandsona):Haha hey me too! :+1: for $. Alright that could work. ---------------------------------------------------------------------------------------------------- [17:31:11] Austin Erlandson(@erlandsona):Yay! @wied03 is the bomb! Turned out it the specs didn’t have jQuery available… I think we just need to add documentation that iterates on this http://rubyist.jaredwhite.com/2015/07/22/how-to-introduce-opal-gently-into-a-legacy-rails-app/ But that also explains the responsibility of the spec_helper. EG: It’s supposed to add the necessary require statements for dependencies that will be used by all you’re specs. And that also you need to require the spec_helper and whatever file you’re testing at the top of your spec file. At least initially until there’s a good solution for meta-programming those import statements that could be built into the opal-rspec-rails gem. Those are my thoughts. ---------------------------------------------------------------------------------------------------- [17:33:06] Brady Wied(@wied03):To follow up on what @erlandsona said, I created an issue here - https://github.com/opal/opal-rspec-rails/issues/2 ---------------------------------------------------------------------------------------------------- [17:45:58] Austin Erlandson(@erlandsona):@wied03 what’s the rake task for running opal specs? Or will they just run as rspecs? ---------------------------------------------------------------------------------------------------- [17:46:30] Austin Erlandson(@erlandsona):EG: right now I run `bundle exec rspec` to run my specs… is there something specific I should do for opal? ---------------------------------------------------------------------------------------------------- [17:52:46] Brady Wied(@wied03):they will not run as rspecs ---------------------------------------------------------------------------------------------------- [17:52:54] Brady Wied(@wied03):bundle exec rake opal:spec usually ---------------------------------------------------------------------------------------------------- [17:54:17] Brady Wied(@wied03):i'm not sure if opal-rails or opal-rspec-rails still include the rake task ---------------------------------------------------------------------------------------------------- [17:54:22] Austin Erlandson(@erlandsona):But since it’s not the spec directory would that matter? ---------------------------------------------------------------------------------------------------- [17:56:15] Austin Erlandson(@erlandsona):Also does opal have a require_tree equivalent? ---------------------------------------------------------------------------------------------------- [17:56:36] Brady Wied(@wied03):maybe elia is still working on that for opal-rspec-rails. in any case, you can just declare your own inside lib/tasks/some_fille.rake like this: ```ruby Opal::RSpec::RakeTask.new('opal:spec' => :environment) do |server, task| app = Rails.application task.files = FileList[ app.root.join('spec/javascripts/**/*_spec{,.js}.{rb,opal}') ] task.default_path = 'spec/javascripts' app.assets.paths.each { |p| server.append_path p } %w(spec/javascripts).each { |p| server.append_path p } end ``` ---------------------------------------------------------------------------------------------------- [17:57:24] Austin Erlandson(@erlandsona):Sweet! ---------------------------------------------------------------------------------------------------- [17:57:51] Brady Wied(@wied03):this is following the same stuff that's on the opal-rspec page. only difference with rails is the dependency on the environment task and `app.assets.paths.each { |p| server.append_path p }` ---------------------------------------------------------------------------------------------------- [17:58:15] Brady Wied(@wied03):yes, `require_tree` works in opal ---------------------------------------------------------------------------------------------------- [17:59:15] Brady Wied(@wied03):http://opalrb.org/docs/guides/v0.9.2/compiler_directives.html ---------------------------------------------------------------------------------------------------- [17:59:27] Austin Erlandson(@erlandsona):Alright working it out now! Got 8 green specs so far! WooooHooo!!! ---------------------------------------------------------------------------------------------------- [18:10:54] Austin Erlandson(@erlandsona):So I’m getting uninitialized constant Opal::RSpec::RakeTask? Thoughts? ---------------------------------------------------------------------------------------------------- [19:11:29] Brady Wied(@wied03):require the rake task first ---------------------------------------------------------------------------------------------------- [19:11:41] Brady Wied(@wied03):see opal-rspec page ---------------------------------------------------------------------------------------------------- [19:41:02] Austin Erlandson(@erlandsona):Got it.

Yay! ---------------------------------------------------------------------------------------------------- ############################## [2016-05-01] ############################## [21:35:48] Jamie Gaskins(@jgaskins):Is there a way to get `Opal::Builder` to use a file cache? ---------------------------------------------------------------------------------------------------- [21:41:29] Jamie Gaskins(@jgaskins):Well, that or something similar. I'm using `rerun` to reload a Roda app in development and I don't want to have to wait for my entire app to recompile each time, so I need something to let it reuse whatever hasn't changed since the last reload. ---------------------------------------------------------------------------------------------------- [22:56:05] Brady Wied(@wied03):@jgaskins - Only places I've used cache with Opal are the Sprockets route or with the webpack loader, which uses Builder, I borrowed the babel loader cache ---------------------------------------------------------------------------------------------------- ############################## [2016-05-02] ############################## [18:37:50] Jamie Gaskins(@jgaskins):@wied03 In Roda, [this](https://github.com/jeremyevans/roda-opal-example/blob/abb63538ffaa0087b530cb5ed7e64cf4b1d19b0f/config.ru#L4-L7 ) is the only way I know of to get an Opal app working: ```ruby class App < Roda plugin :assets, js: ['test.rb'], js_opts: { builder: Opal::Builder.new } compile_assets # This only runs once, at app startup end ``` ---------------------------------------------------------------------------------------------------- [18:41:49] Brady Wied(@wied03):@jgaskins - @cj has done work with Roda and Opal. Perhaps he can shed some light on what he does ---------------------------------------------------------------------------------------------------- [19:35:35] CJ Lazell(@cj):@jgaskins I just use webpack with roda :) ---------------------------------------------------------------------------------------------------- [02:38:26] Jamie Gaskins(@jgaskins):@wied03 Yeah, I was hoping for something like the `Sprockets::FileCache`. Looking at the code for `Opal::Builder`, though, it doesn't look like it supports it. ---------------------------------------------------------------------------------------------------- [11:14:26] Elia Schito(@elia):@jgaskins there's an old cache-related PR from adam, maybe you can give it a try (if it merges cleanly with master), if it works well it can be merged in master I guess… ---------------------------------------------------------------------------------------------------- [14:55:33] Brady Wied(@wied03):@jgaskins - Why would you want to cache directly with Builder without some higher level code doing it ? ---------------------------------------------------------------------------------------------------- ############################## [2016-05-03] ############################## [17:34:29] Forrest Chang(@fkchang):I'm coining the term "Node fatigue" unless it's already been coined https://twitter.com/fkchang2000/status/727551409151840256 ---------------------------------------------------------------------------------------------------- [17:34:41] Forrest Chang(@fkchang):I do see opal helping to remedy such ---------------------------------------------------------------------------------------------------- [20:21:47] Mitch VanDuyn(@catmando):Cool I just put a comment on that... a hidden item in all this is why go to node in the first place? Probably because of the beauty of one language everywhere. So opalrb gives a better solution to the same root problem. ---------------------------------------------------------------------------------------------------- ############################## [2016-05-04] ############################## [00:50:51] Forrest Chang(@fkchang):What versions of opal are people using?

Had a weird issue come up, this is with Opal 0.9.2. I got an error with my built code because the compiled JS was trying to call Opal.to_a and failed. I looked and saw that in the JS context there's an Opal.to_ary but no Opal.to_a. On a whim, I added a script tag and did Opal.to_a = Opal.to_ary. Then my stuff ran just fine. Is this some kind of compilation bug perhaps? Or do I need to do something different with how I'm building my Opal files. Thanks! ---------------------------------------------------------------------------------------------------- [15:25:06] Elia Schito(@elia):@jaredcwhite it's a bug, if you can find which code is producing the `.to_a` please file an issue and we'll fix it ---------------------------------------------------------------------------------------------------- [15:25:40] Elia Schito(@elia):of course if it's 3rd party stuff it's a matter of updating the 3rd party code :) ---------------------------------------------------------------------------------------------------- [15:33:31] Jared White(@jaredcwhite):@elia I think I pinpointed the problem.

Figured it might help by not having to restart the entire app when I'm only modifying front-end stuff. But that doesn't seem to be working, either. I think it might be the fact that it uses its own middleware. ---------------------------------------------------------------------------------------------------- [04:22:01] Jamie Gaskins(@jgaskins): ---------------------------------------------------------------------------------------------------- [04:24:09] Jamie Gaskins(@jgaskins): ---------------------------------------------------------------------------------------------------- [04:26:22] Jamie Gaskins(@jgaskins): ---------------------------------------------------------------------------------------------------- [04:29:38] Jamie Gaskins(@jgaskins):Deleting messages because I realized a problem I'm having with Rack apps is due to something I've already reported that @elia already told me how to solve. ---------------------------------------------------------------------------------------------------- [04:38:30] Jamie Gaskins(@jgaskins):@elia Does it seem reasonable to rework `Opal::Server` to delegate asset compilation to some smaller, more focused `Opal::AssetServer` Rack app? I ended up having to write my own asset-compiling Rack app to delegate to in this app. :-) ---------------------------------------------------------------------------------------------------- [05:58:08] Elia Schito(@elia):@jgaskins sounds interesting, anything cleaner or more manageable is welcome, it's ok if you wanna open a PR with your current code just to start the conversation ---------------------------------------------------------------------------------------------------- [13:29:37] Jamie Gaskins(@jgaskins)::+1: ---------------------------------------------------------------------------------------------------- [21:25:52] roupen(@roupen):hi guys, I was checking out the opal docs and was trying out some of the code for accessing the native window object and for some reason it's returning null for me.

I tried using the ERB in the gem, and it works, BUT, when you change the config file in rails and restart, it does not take the change in the config... Is there some way I can force the file to get blown away on server start? ---------------------------------------------------------------------------------------------------- [22:06:34] Elia Schito(@elia):@catmando you can use sprockets directive to link that file to another so its refreshed whenever the first one is ---------------------------------------------------------------------------------------------------- [22:06:47] Elia Schito(@elia):which version of sprockets are you running? ---------------------------------------------------------------------------------------------------- [22:07:07] Mitch VanDuyn(@catmando):3.0? ---------------------------------------------------------------------------------------------------- [22:07:07] Mitch VanDuyn(@catmando):yes ---------------------------------------------------------------------------------------------------- [22:07:50] Elia Schito(@elia):https://github.com/rails/sprockets/tree/3.x#the-directive-processor ---------------------------------------------------------------------------------------------------- [22:08:57] Elia Schito(@elia):https://github.com/rails/sprockets/tree/3.x#the-depend_on-directive ---------------------------------------------------------------------------------------------------- [22:09:01] Elia Schito(@elia):this should do ---------------------------------------------------------------------------------------------------- [14:53:56] Mitch VanDuyn(@catmando):@fkchang @elia @jgaskins @ajjahn @wied03 any ideas on the above?

The key is set in an config file on the server, so it would just be nice to have the gem get it down to the client without any extra coding. ---------------------------------------------------------------------------------------------------- [14:58:52] Mitch VanDuyn(@catmando):Specifically this is to enable pusher.com integration with reactive-record FYI ---------------------------------------------------------------------------------------------------- [15:00:08] Brady Wied(@wied03):well, if you're OK using what could be considered a hack by modern Sprockets standards, you could create a config class that's in an ERB file ---------------------------------------------------------------------------------------------------- [15:00:29] Brady Wied(@wied03):and ERB would drop in the API key, sprockets would compile it and you'd have a constant in an Opal class ---------------------------------------------------------------------------------------------------- [15:00:55] Mitch VanDuyn(@catmando):yeah that is where I was going. Can I assume ERB is there if sprockets is there? ---------------------------------------------------------------------------------------------------- [15:01:10] Brady Wied(@wied03):historically yes, but they are discouraging that I think ---------------------------------------------------------------------------------------------------- [15:01:26] Brady Wied(@wied03):might be better to create a Rake task that code gens that for you ---------------------------------------------------------------------------------------------------- [15:01:27] Mitch VanDuyn(@catmando):soooo what is the proposed alternative, I guess that is what I am asking ---------------------------------------------------------------------------------------------------- [15:01:54] Brady Wied(@wied03):the rails js routes project hooks that in with their railtie such that it generates an asset fairly automatically ---------------------------------------------------------------------------------------------------- [15:01:56] Mitch VanDuyn(@catmando):but then the user has to remember to run this rake task when ever they change the config ---------------------------------------------------------------------------------------------------- [15:02:06] Elia Schito(@elia):@catmando also dumping stuff as json in data-attributes or meta tags ---------------------------------------------------------------------------------------------------- [15:02:30] Brady Wied(@wied03):@elia - he wants it to be automatic without extra coding ---------------------------------------------------------------------------------------------------- [15:02:52] Mitch VanDuyn(@catmando):yeah - I know how to send values between client and server :-) ---------------------------------------------------------------------------------------------------- [15:03:07] Mitch VanDuyn(@catmando):but @wied03 has it right. ---------------------------------------------------------------------------------------------------- [15:03:18] Mitch VanDuyn(@catmando):currently I would do something like this in the gem ---------------------------------------------------------------------------------------------------- [15:04:02] Elia Schito(@elia):sorry, kinda skimmed the question and thrown stuff at the wall in the hope something sticked :smile: ---------------------------------------------------------------------------------------------------- [15:04:54] Brady Wied(@wied03):@catmando - maybe https://github.com/railsware/js-routes has a good way they do that ---------------------------------------------------------------------------------------------------- [15:05:24] Mitch VanDuyn(@catmando):```ruby #config.rb.erb module MyGemConfig def value '<%= MyGemConfig.value %>' end end ``` ---------------------------------------------------------------------------------------------------- [15:06:58] Mitch VanDuyn(@catmando):looks like ERB is the way to go..

I'll give it a try. I think CSS hot reloading would be good, let the compilers handle making it css. (I wouldn't make it compiler specific) ---------------------------------------------------------------------------------------------------- [21:29:25] Forrest Chang(@fkchang):@cj for sass I'd probably target rails, because I'll know what the convention is, I'll expect the asset pipeline to server up the compiled css files - for non rails, I'm not sure what I'd do ---------------------------------------------------------------------------------------------------- [21:30:54] Brady Wied(@wied03):@fkchang - Does this reinvent the wheel since webpack/other bundlers do this kind of thing ? ---------------------------------------------------------------------------------------------------- [21:32:26] CJ Lazell(@cj):webpack dev server does it, but I found it adds 1 minute onto the startup compile time. I personally switched to livereload, but for the video demo hotreloading would be better ---------------------------------------------------------------------------------------------------- [21:35:08] Forrest Chang(@fkchang):@wied03 yes and no, it is an all ruby/opal, self contained thing, so if you're doing any kind of opal/ruby webserver, it should be able to just drop in and you won't have to do anything w/webpack or similar. I do believe we will want to straddle the hybrid approach w/opal and rails, w/sprockets serving up all the things the normal Rails ecosystem, and webpack or similar for being a "1st class JS citizen". While I do favor moving as much js to webpack, I see an "all webpack solution" being only one of a few permutations, and not particularly appealing to most Rails programmers (who I think is the largest demographic likely to want to do opal programming) ---------------------------------------------------------------------------------------------------- [21:36:03] Brady Wied(@wied03):fair enough, maybe add that content to your repo as an FYI/vision for the project ? ---------------------------------------------------------------------------------------------------- [21:36:47] Forrest Chang(@fkchang):And the other thing is it works here and now for sinatra, rails and reactrb - I definitely feel getting the word out that we have modern web development tools like react.js does, right now, is useful for getting some attention to the assorted opal projects, as hopefully some momentum ---------------------------------------------------------------------------------------------------- [21:37:15] Forrest Chang(@fkchang):@wied03 I'm up for that, I'll see what I can do ---------------------------------------------------------------------------------------------------- [21:37:37] Brady Wied(@wied03):nothing fancy, just that way in your README people can see how you envision this ---------------------------------------------------------------------------------------------------- [21:52:12] Forrest Chang(@fkchang):@wied03 how's this https://github.com/fkchang/opal-hot-reloader#vision ---------------------------------------------------------------------------------------------------- [21:53:42] Brady Wied(@wied03)::+1: ---------------------------------------------------------------------------------------------------- ############################## [2016-05-18] ############################## [01:50:14] Barrie Hadfield(@barriehadfield):@fkchang I really like your hybrid vision with gems and sprockets for all things rails related and NPM/webpack for FE assets.

For example, if `foo.rb` requires `bar.rb`, which dynamic_requires `baz.rb`, this code causes a problem: ```ruby # foo.rb require 'bar' Bar.new.call ``` ```ruby # bar.rb dynamic_require('baz').then do class Bar def call Baz.new(self) end end end ``` So you'd have to know if not only your direct dependencies, but also your _indirect_ dependencies, have any async requires. ---------------------------------------------------------------------------------------------------- [09:05:01] Earl Balai Jr(@earlbalai):Anyone else having this issue on Rails 5.0.0.rc1 "activesupport-5.0.0.rc1/lib/active_support/dependencies.rb:293:in `require': cannot load such file -- rack/showexceptions (LoadError)" ---------------------------------------------------------------------------------------------------- [09:10:04] Alexandr Smirnov(@JelF):я fixed it in opal-rails ---------------------------------------------------------------------------------------------------- [09:10:22] Alexandr Smirnov(@JelF):in january as far as i remember ---------------------------------------------------------------------------------------------------- [15:53:29] Mitch VanDuyn(@catmando):For react.rb I would like to include a directory inside of the react.rb gem, that would contain sources for each react.js major version. ---------------------------------------------------------------------------------------------------- [15:54:28] Mitch VanDuyn(@catmando):I thought I would do it like opal-browser, where some of the files (like interval.rb) are NOT included in the base browser require, and you can then explicitly require them. ---------------------------------------------------------------------------------------------------- [15:54:41] Mitch VanDuyn(@catmando):But I can't seem to get it to work. ---------------------------------------------------------------------------------------------------- [15:54:46] Mitch VanDuyn(@catmando):I have the following structure: ---------------------------------------------------------------------------------------------------- [15:58:02] Mitch VanDuyn(@catmando):```text |-lib |-reactive-ruby |- etc |-sources |-react_v13.js |-react_v14.js |-react_v15.js |-reactive-ruby.rb ``` And reactive-ruby.rb looks like this ```ruby if RUBY_ENGINE == 'opal' #require 'sources/react_v13.js' #comment this out for release, leave in for testing with which ever version you like require 'react/top_level' require 'react/observable' require 'react/component' require 'react/component/base' require 'react/element' require 'react/event' require 'react/api' require 'react/validator' require 'react/rendering_context' require 'react/state' require 'reactive-ruby/isomorphic_helpers' require 'rails-helpers/top_level_rails_component' require 'reactive-ruby/version' else require 'opal' require 'opal-browser' require 'opal-activesupport' require 'reactive-ruby/version' require 'reactive-ruby/rails' if defined?(Rails) require 'reactive-ruby/isomorphic_helpers' require 'reactive-ruby/serializers' Opal.append_path File.expand_path('../', __FILE__).untaint Opal.append_path File.expand_path('../sources', __FILE__).untaint # I tried this to see if fixes anything end ``` ``` ---------------------------------------------------------------------------------------------------- [15:59:00] Mitch VanDuyn(@catmando):but when I do a `require 'reactive-record/sources/react_v13.js'` i get: ---------------------------------------------------------------------------------------------------- [15:59:16] Mitch VanDuyn(@catmando):Sprockets::FileNotFound at / couldn't find file 'reactive-ruby/sources/react_v13' with type 'application/javascript' ---------------------------------------------------------------------------------------------------- [16:00:02] Mitch VanDuyn(@catmando):As far as I can see I am following the exact structure of opal-browser, but yet can't get it to work... ---------------------------------------------------------------------------------------------------- [16:00:26] Mitch VanDuyn(@catmando):any help appreciated @elia any ideas?

Has anyone made a Rails engine that uses Opal? Currently I'm having trouble getting it to use OpalHelper#javascript_include_tag from opal-rails (0.8.1) ---------------------------------------------------------------------------------------------------- [20:15:57] Doug Orleans(@dougo):which is what it uses when it's an app. ---------------------------------------------------------------------------------------------------- [21:01:05] Doug Orleans(@dougo):hm, when I use rails console, `helper.method(:javascript_include_tag)` gets it from OpalHelper. But from inside my application layout, it's getting the one from Sprockets::Rails::Helper. ---------------------------------------------------------------------------------------------------- [21:04:58] Jamie Gaskins(@jgaskins):@dougo Is there a reason you want to get it to invoke the `OpalHelper` one specifically? ---------------------------------------------------------------------------------------------------- [21:05:41] Doug Orleans(@dougo):Yes, because that's the one that generates the code to actually call my application code. Otherwise it just defines a bunch of modules but never starts the app. ---------------------------------------------------------------------------------------------------- [21:06:23] Jamie Gaskins(@jgaskins):What version of Rails are you on? ---------------------------------------------------------------------------------------------------- [21:06:25] Doug Orleans(@dougo):specifically, it calls `Opal::Processor.load_asset_code(sprockets, source)` ---------------------------------------------------------------------------------------------------- [21:06:35] Doug Orleans(@dougo):rails 4.2.6 ---------------------------------------------------------------------------------------------------- [21:07:31] Jamie Gaskins(@jgaskins):That's really weird. I use the stock `javascript_include_tag` in my application layout all the time and it loads right up. ---------------------------------------------------------------------------------------------------- [21:07:50] Doug Orleans(@dougo):yeah, I think it's something about how Rails engines are different from applications. ---------------------------------------------------------------------------------------------------- [21:07:57] Jamie Gaskins(@jgaskins):Oh, right, engines ---------------------------------------------------------------------------------------------------- [21:08:40] Doug Orleans(@dougo):I've been running into a few gotchas. Like, it doesn't auto-require all the gems it depends on, you have to require them all manually. ---------------------------------------------------------------------------------------------------- [21:08:50] Doug Orleans(@dougo):took me a while to track that down... ---------------------------------------------------------------------------------------------------- [21:09:50] Doug Orleans(@dougo):@jgaskins, I assume the "stock" `javascript_include_tag`in your app is actually coming from opal-rails. At least that's what I determined from my app (before I converted it to an engine) ---------------------------------------------------------------------------------------------------- [21:18:13] Jamie Gaskins(@jgaskins):Huh, weird. Opal registers itself with Sprockets as the handler for `.rb` and `.opal` files, so it shouldn't need to do that. It might be to paper over inconsistencies between Sprockets versions, though. ---------------------------------------------------------------------------------------------------- [21:49:38] Doug Orleans(@dougo):hm, seems to be a consequence of using `isolate_namespace` in the engine. ---------------------------------------------------------------------------------------------------- [21:50:33] Doug Orleans(@dougo):I get that that prevents helpers from the engine from polluting the app, but in this case it seems to be preventing a helper from the engine's dependencies from being visible in the engine. ---------------------------------------------------------------------------------------------------- [22:00:00] Doug Orleans(@dougo):aha! found this hint: http://api.rubyonrails.org/classes/Rails/Engine.html#class-Rails::Engine-label-Isolated+engine-27s+helpers ---------------------------------------------------------------------------------------------------- [22:00:17] Doug Orleans(@dougo):adding `helper OpalHelper` into my engine's ApplicationController did the trick. whew! ---------------------------------------------------------------------------------------------------- [22:09:27] Jamie Gaskins(@jgaskins):@dougo Nice! :+1: ---------------------------------------------------------------------------------------------------- [14:12:11] chewedon(@chewedon):Hi... ---------------------------------------------------------------------------------------------------- [14:12:48] chewedon(@chewedon):So...Opal is a compiler for Ruby to Javascript ?

Google will give you TONS of gory and nasty details (in all directions) -- but basically a huge fight broke out on a github issue request asking to kick people off of the project for behavior outside of the project (which is quite rude, in my opinion, and unsurprising that it led to a fight). It has been an unfortunately notable incident in ongoing debates about social responsibility in open source projects, especially because it's hard for folks to realize that it has been resolved -- there is no ongoing issue in the Opal project that I know of. ---------------------------------------------------------------------------------------------------- [19:56:25] Brock Wilcox(@awwaiid):Adam Beynon, as I understand it, was a bit part of the resolution.

Not sure if that ever actually got off the ground. I'm looking at creating an official JS library for a tool I'm building (nothing specifically related to Opal), and my current code is mostly Opal-based. I might try the crazy route of actually releasing it as a compiled Ruby-to-JS file if it could include only a small subset of the Opal runtime. Otherwise I'm just going to rewrite it in JS (probably ES6 + Babel). ---------------------------------------------------------------------------------------------------- [11:53:13] Elia Schito(@elia):@jaredcwhite `require 'opal/mini'` instead of `opal` should do the trick, not sure if it's suitable for a general purpose library tho ---------------------------------------------------------------------------------------------------- [11:53:37] Elia Schito(@elia):https://github.com/opal/opal/blob/master/opal/opal/mini.rb ---------------------------------------------------------------------------------------------------- [14:31:55] Jamie Gaskins(@jgaskins):@elia Well, for a library, it's a good idea not to load Opal at all (on the front end, at least). ;-) The app using the library should decide how to load Opal. If an app loads it from a CDN but a lib loads it from the gem, you load the runtime twice. ---------------------------------------------------------------------------------------------------- [14:35:32] Elia Schito(@elia):indeed that's my general opinion too, but then you have stuff like asciidoctor.js and looks like a legit use case :D ---------------------------------------------------------------------------------------------------- [15:09:16] Vais Salikhov(@vais):@catmando in reference to https://github.com/opal/opal/pull/1474 I have no objections to the PR as it stands at https://github.com/opal/opal/pull/1474/commits/ad833a3e86ed95e6ac640f6ba7d63cd249db4a1a.

I thought the change to allow `null` had broken specs for kwargs (since kwargs are implemented with hashes), but @elia said it was caused by an incompatibility with mspec. So, never mind. :-) ---------------------------------------------------------------------------------------------------- [23:22:59] Jared White(@jaredcwhite):@elia Sweet! I'll definitely check that out. @jgaskins I could probably provide a variant of the library not including any of the Opal code itself, if the app wanted to load Opal separately. Yes? ---------------------------------------------------------------------------------------------------- [23:23:43] Jared White(@jaredcwhite):Also, FWIW, I added my 2c in that Reddit thread on Opal. :clap: ---------------------------------------------------------------------------------------------------- ############################## [2016-06-07] ############################## [00:02:23] Elia Schito(@elia):@/all I'm about to release 0.9.3 which contains just a minute fix, but given the recent problems rubygems had with symlinks if someone can confirm http://cl.ly/0E0l1D0U0X3x gets installed without errors?

Glad to hear. @catmando sure thing! :beer: ---------------------------------------------------------------------------------------------------- [16:18:49] Jamie Gaskins(@jgaskins):@jaredcwhite You could, but is there any value in making an assumption about how the app using your library is loading Opal? In general, I'm all for loading all dependencies of your code in the same file, and the runtime is definitely a dependency. :-) However, I kinda consider it similarly to running MRI or RSpec on the server. You can safely assume the Ruby runtime is loaded. Similarly, specs generally only load the code they're specifying; RSpec is assumed to be loaded elsewhere. ---------------------------------------------------------------------------------------------------- ############################## [2016-06-08] ############################## [01:20:46] Jonathan Simpson(@jsimpson):@fkchang honestly, most of them, but your most recent post about refactoring opal-hot-reloader helped me sort out some confusion I had about rspec and writing specs ---------------------------------------------------------------------------------------------------- [09:47:57] Vais Salikhov(@vais):@fkchang thanks :smile: Day job and family been keeping me busy ---------------------------------------------------------------------------------------------------- [17:36:16] Brady Wied(@wied03):FYI, i toyed around with React Native and Opal, https://github.com/wied03/react_native_sample, still some decent obstacles there ---------------------------------------------------------------------------------------------------- [17:38:23] Brady Wied(@wied03):and things w/ React native have changed a lot since zetachang's original sample ---------------------------------------------------------------------------------------------------- [17:57:36] Mitch VanDuyn(@catmando):@wied03 cool! ---------------------------------------------------------------------------------------------------- [21:23:52] Mitch VanDuyn(@catmando):opal-rails depends on opal-rspec 0.4.3 ??? so there is no way to run opal-rspec 0.5 with opal rails unless you take latest opal-rails from master? ---------------------------------------------------------------------------------------------------- [22:01:30] Brady Wied(@wied03):all roads run through elia :) ---------------------------------------------------------------------------------------------------- [23:52:15] Elia Schito(@elia):heyhey :D ---------------------------------------------------------------------------------------------------- [23:54:00] Elia Schito(@elia):@wied03 the new opal-rails has no direct opal-rspec bound, and I started som work around opal-rspec-rails, but I'm kinda stuck on that for lack of time (surprise!) could definitely use some help there ---------------------------------------------------------------------------------------------------- [23:54:05] Elia Schito(@elia)::) ---------------------------------------------------------------------------------------------------- ############################## [2016-06-09] ############################## [13:05:48] Mitch VanDuyn(@catmando):@elia do u know if there r any barriers to getting opal-rails on master running with opal 0.8?

My guess as to his motive is that metaprogramming is fun. ;-) @catmando In your example, `div` points to the same function in the VM as `method_missing`, wired up at compile time. The only extra cost is inside `method_missing`, which is probably reduced to almost 0 after a couple executions of it when the JIT gets ahold of it. Would be best not to conjecture and run benchmarks instead. :-) ---------------------------------------------------------------------------------------------------- [18:56:17] Jikku Jose(@JikkuJose):@fkchang Hey, thanks for replying! This is my setup: https://github.com/JikkuJose/react-lab/tree/feature-opal_support I am trying to _import_ a simple Ruby class to a typical React project. ---------------------------------------------------------------------------------------------------- [18:58:15] Jikku Jose(@JikkuJose):This is the Ruby file: https://github.com/JikkuJose/react-lab/blob/feature-opal_support/src/js/app/para.rb This is how I am hoping to us it: https://github.com/JikkuJose/react-lab/blob/feature-opal_support/src/js/app.jsx#L9 Note: Now, I am referring to the _jsx_ file instead of the .rb file. But didn't work when I was using it. ---------------------------------------------------------------------------------------------------- [18:58:42] Jikku Jose(@JikkuJose):Quick question: Opal compiles to es5? ---------------------------------------------------------------------------------------------------- [19:05:39] Jikku Jose(@JikkuJose):Also, shouldn't `opalrb-loader` be listed in `devDependencies`? (https://github.com/zetachang/opalrb-loader/blob/5fe749e062678e61e5f78cf44ecf8d5a3b22eedb/examples/simple/package.json#L8) ---------------------------------------------------------------------------------------------------- [19:07:10] Jikku Jose(@JikkuJose):Is there any equivalent for specifying the Ruby class as the one thats being exported? I think everything is getting compiled well, but I am unable to refer to the class I am creating. ---------------------------------------------------------------------------------------------------- [19:14:18] Ilya Bylich(@iliabylich):To get a Ruby class form JS you need to call `Opal.YourClass`. To create its instance use `.$new()`, to call your own method call `.$your_method()`. For your code it should be `Opal.Paragraph.$new().$text()`. ---------------------------------------------------------------------------------------------------- [19:14:33] Ilya Bylich(@iliabylich):No, opal doesn't support ES5 ---------------------------------------------------------------------------------------------------- [19:19:01] Ilya Bylich(@iliabylich):And ideally you should use your Ruby classes from your Ruby code, it can be really painful to use compiled JS directly (talking about things like Ruby blocks). ---------------------------------------------------------------------------------------------------- [19:29:10] Jikku Jose(@JikkuJose):Wow! Thats great help! ---------------------------------------------------------------------------------------------------- [19:32:55] Jikku Jose(@JikkuJose):@iliabylich I was able to use the Ruby class like you mentioned. I understand its not very pretty, but I was just trying to see if it was possible. It definitely looks awful to write `Opal.Paragraph.$new().$text()`; but the capability to do Ruby along side JS feels cool. Certainly not for production, but to see the value of webpack. Loud Thought: If Ruby classes could have been addressed like normal es6 classes this would have been a great way to use Opal along side, so that we could code in either Ruby or es6. ---------------------------------------------------------------------------------------------------- [20:12:21] Dino Maric(@dixpac):Hi all!

I've tried backticking it like `module.exports = MyRubyView` but that throws an error in the compiled js: "import and export may only appear at the top level". Googling various opal/export/modules failed, so I thought I might ask here :) ---------------------------------------------------------------------------------------------------- [14:36:54] Jamie Gaskins(@jgaskins):@scally I don't think so. The entire file gets wrapped in a closure by the compiler. ---------------------------------------------------------------------------------------------------- [14:53:58] Jared White(@jaredcwhite):@elia Blog post is ready to roll for 0.10 final release https://github.com/opal/opal.github.io/pull/37 ---------------------------------------------------------------------------------------------------- [17:22:19] Sean Scally(@scally):@jgaskins thanks for the response; is there any alternative approach I could use if I wanted to write something in opal that I could easily import from JS without having to wrap everything in `$`'s? ---------------------------------------------------------------------------------------------------- [17:30:04] Jamie Gaskins(@jgaskins):@scally Ah, I think I see what you mean. You want to be able to do something like this? ```ruby class Foo def bar end end `module.exports = #{Foo}` ``` And then elsewhere in JS: ```javascript import Foo from './foo'; var f = Foo.new(); foo.bar(); ``` ---------------------------------------------------------------------------------------------------- [17:34:58] Forrest Chang(@fkchang):@scally help me understand the situation, so isn't ```module.exports``` common.js/node modules -- i.e. it doesn't make sense outside of node - I'm not sure how code like that gets compiled to work on the client via browerify/webpack, etc.. I guess u want to do something like what @jgaskins posted? ---------------------------------------------------------------------------------------------------- [17:39:25] Jamie Gaskins(@jgaskins):@fkchang I figured he wanted to convert the compiled Ruby to a JS-like object because of this: > wanted to write something in opal that I could easily import from JS without having to wrap everything in `$`'s ---------------------------------------------------------------------------------------------------- [17:49:12] Sean Scally(@scally):@jgaskins Yes, you got it in your example ---------------------------------------------------------------------------------------------------- [17:56:41] Jamie Gaskins(@jgaskins):@scally Currently, there's no way to convert a Ruby class into an object without `$` method prefixes. AFAIK, the `$` prefix exists purely so you can have methods and ivars with the same names (like `attr_reader`s). That might be the biggest obstacle to getting something like this working. ---------------------------------------------------------------------------------------------------- [18:02:09] Sean Scally(@scally):OK, got it. Appreciate your response. :) ---------------------------------------------------------------------------------------------------- [18:03:37] Sean Scally(@scally):FWIW, my use case is React Native; I've been building a RN app with ES6 and added a gulp task to convert Coffeescript/CJSX to JS, using the backticks in Coffeescript to import/export as needed to emit JS that Coffeescript didn't support, and was hoping I could extend the same methodology to use RN with Opal. ---------------------------------------------------------------------------------------------------- [18:03:56] Jamie Gaskins(@jgaskins):No worries. I like to make stuff usable easily and I think it would be a lot of fun to be able to use something like that. Right now, it's easy to call out to JS from Ruby, but going the other direction still has a fair bit of friction. ---------------------------------------------------------------------------------------------------- [18:05:01] Sean Scally(@scally):I saw there's a Github sample project for RN/Opal but it seems outdated & I have some concerns that the methodology it used (skipping the npm ecosystem) made it harder to update as RN changed or interop with the rest of the npm ecosystem ---------------------------------------------------------------------------------------------------- [18:05:36] Sean Scally(@scally):I was looking for a way to approach RN/Opal in a way that still used the npm infrastructure instead of rake/bundler ---------------------------------------------------------------------------------------------------- [18:05:56] Jamie Gaskins(@jgaskins):The one @wied03 posted? ---------------------------------------------------------------------------------------------------- [18:06:24] Sean Scally(@scally):This is the one I meant: https://github.com/zetachang/opal-native ---------------------------------------------------------------------------------------------------- [18:10:01] Sean Scally(@scally):Looking over the https://github.com/wied03/react_native_sample one now... This might be closer to what I'm looking to do, thanks for pointing me in that direction. Looks like using a webpack server approach with opal-webpack? ---------------------------------------------------------------------------------------------------- [20:01:28] Forrest Chang(@fkchang):@jgaskins I'm thinking maybe a library that converts opal classes/objects into something that looks more native Javascript like could be in order, it would be limitd where one couldn't have a property and method w/the same name. That could be a good too for publicity, if we made a kick but opal lib that was easily usuable by JS. I think that was a selling point of coffeescript, easily usuable by JS because it's just syntactic sugar ---------------------------------------------------------------------------------------------------- [20:21:57] Yehonathan Sharvit(@viebel):@dixpac were you able to require a gem with opal, compile to javascript and run the javascript? ---------------------------------------------------------------------------------------------------- [20:53:19] Mitch VanDuyn(@catmando):@viebel - i have done that... ---------------------------------------------------------------------------------------------------- ############################## [2016-06-24] ############################## [03:10:41] Yehonathan Sharvit(@viebel):@catmando how did you do that? ---------------------------------------------------------------------------------------------------- [03:11:45] Mitch VanDuyn(@catmando):I think instructions are in opal readme ---------------------------------------------------------------------------------------------------- [03:12:09] Mitch VanDuyn(@catmando):I'm about to go to bed.

This adds their require paths to Opal's list of require paths. Then you can `require` them in your client-side app as normal Ruby libraries. Unfortunately, for it to work, those gems can't use anything Opal doesn't support, like threads, files (in the browser), native extensions, POSIX stuff (`fork`, processes), `Net::HTTP`, and other things that can't be done in the browser (at least, not the way Ruby does it). ---------------------------------------------------------------------------------------------------- ############################## [2016-06-27] ############################## [15:02:06] Martin Becker(@Thermatix):for the things that the browser does support, why not monkey-patch in interfaces so that when the gems make calls to those things, it simply-redirects any calls to the correct classes/methods ---------------------------------------------------------------------------------------------------- [15:02:22] Martin Becker(@Thermatix):and for the things that don't, error with somthing helpfull? ---------------------------------------------------------------------------------------------------- [20:24:07] Mitch VanDuyn(@catmando):@wied03 @elia not sure where to report this, but I just down graded from opal 9x to opal 8x, and neither opal-rspec or opal-rails reported an issue, but stayed at version 0.9.

If you rewrote that code instead like this: ```ruby module Foo end class Foo::Whack end module Foo::Bar end class Foo::Bar::Baz def self.test(s) const_get s.to_s end def self.test1 test(Whack) end end ``` Both of your test methods would fail, but your lookup method would still work. ---------------------------------------------------------------------------------------------------- ############################## [2016-06-29] ############################## [08:17:11] Mehmet Beydogan(@beydogan):@iliabylich I will try that, thanks ---------------------------------------------------------------------------------------------------- ############################## [2016-07-01] ############################## [16:46:55] Doug Orleans(@dougo):I mean the actual array you get from `Exception#backtrace` ---------------------------------------------------------------------------------------------------- [16:47:29] Doug Orleans(@dougo):would be nice if there were a way to tell it to use source maps, or else a way to translate it afterward ---------------------------------------------------------------------------------------------------- [16:47:51] Elia Schito(@elia):I see, I think it's possible but not easy, and would involve dealing with source maps and doing the mapping manually ---------------------------------------------------------------------------------------------------- [16:48:06] Doug Orleans(@dougo):Yep. ---------------------------------------------------------------------------------------------------- [16:48:16] Elia Schito(@elia):would probably be cool if browser offered an api to do that… ---------------------------------------------------------------------------------------------------- [16:48:30] Doug Orleans(@dougo):I started going down that road and decided I'd ask if someone already did this... ---------------------------------------------------------------------------------------------------- [16:44:34] Doug Orleans(@dougo):Is there a way to have exception backtraces use source maps? ---------------------------------------------------------------------------------------------------- [16:46:02] Elia Schito(@elia):@dougo on browser should already be the case, certainly on Safari (which I use most of the time) ---------------------------------------------------------------------------------------------------- ############################## [2016-07-02] ############################## [00:45:52] Forrest Chang(@fkchang):@dougo if u figure out a way, I'd be interested ---------------------------------------------------------------------------------------------------- [05:37:05] Forrest Chang(@fkchang):@/all per @catmando 's suggestion, I've made the 1st release of opal-console devtools https://chrome.google.com/webstore/detail/opal-console/bloiggoenjaanceeabeipidehkahdcam ---------------------------------------------------------------------------------------------------- [07:57:44] Elia Schito(@elia):@catmando about the 0.9 -> 0.8 downgrade the right place to report is opal-rails ---------------------------------------------------------------------------------------------------- ############################## [2016-07-03] ############################## [20:47:03] Forrest Chang(@fkchang):@/all just found out that opal-console also works on opera! ---------------------------------------------------------------------------------------------------- [21:02:53] Jamie Gaskins(@jgaskins)::+1: ---------------------------------------------------------------------------------------------------- ############################## [2016-07-04] ############################## [03:12:12] Doug Orleans(@dougo):@fkchang I hacked together this for opal-minitest: https://github.com/aostrega/opal-minitest/pull/11/files#diff-f217b36f75562cb1130e401df1660c89 ---------------------------------------------------------------------------------------------------- [03:12:52] Doug Orleans(@dougo):it only works because it uses Opal::Server though.

One thing though, is it being maintained & considered production-ready? I have an existing JS app (MERN stack) & plan on converting it into Opal/Reactrb. I know this is a broad question, & I would appreaciate any opinions on the matter! ---------------------------------------------------------------------------------------------------- [03:06:24] meh.(@meh):Qudware, it's maintained, and people use it in production ---------------------------------------------------------------------------------------------------- [03:08:19] hayley(@hayley):@Qudware I'm just some random, but I'd say it's production ready. I've been following Opal's development since 2014 or so and I'd definitely say it's in active development. I have a few projects that have been using it for awhile (none open source unfortunately), and it's definitely made JS more pleasant to work with. And if you're specifically interested in reactrb, there's an active gitter chat here for that too. ---------------------------------------------------------------------------------------------------- [04:31:25] Jamie Gaskins(@jgaskins):@Qudware One of my [Clearwater](https://github.com/clearwater-rb/clearwater) apps has been in production since last year, around 3k LOC and monitors the status of food deliveries in real time across 55 markets all over the country. It'll be fine for whatever ya need. ;-) ---------------------------------------------------------------------------------------------------- [19:19:19] Mitch VanDuyn(@catmando):trying to get opal working with middleman does anybody know any tricks (@hayley, @fkchang) ? ---------------------------------------------------------------------------------------------------- [19:20:58] Mitch VanDuyn(@catmando):@Qudware - We are using it all fairly large app (about 18K sloc of opal code I think) its in beta test. It uses opal + reactrb. Opal is very stable, and I can remember only finding one very obscure bug in the last couple of years. ---------------------------------------------------------------------------------------------------- [19:32:17] hayley(@hayley):@catmando what version of middleman? Where are you getting stuck? If you're using v3, it's stuck at Opal 0.7.X I believe, due to sprockets compatibility. I actually have a v3 project where I set up something external so that I could use a modern version of opal, but I was never quite thrilled with it. And I'll post some example projects in a bit. ---------------------------------------------------------------------------------------------------- [19:33:26] Mitch VanDuyn(@catmando):i;m trying to use latest and greatest (v4) I found your blog post, but as you said that's v3... ---------------------------------------------------------------------------------------------------- [19:35:06] hayley(@hayley):@catmando yeah, I actually feel bad that that ranks since it's years old at this point. Time for an update... ---------------------------------------------------------------------------------------------------- [19:38:04] hayley(@hayley):here's a couple of sample projects: https://github.com/opal/opal.github.io/tree/source (make sure you're on the source branch) and https://github.com/fkchang/opal-playground - both are v4. And I'll see if I can put together quick instructions in the next 15 minutes or so (and write a more current blog post at some point too) ---------------------------------------------------------------------------------------------------- [19:49:10] hayley(@hayley):Here's half the instructions for now: sprockets is no longer a default part of the middleman install, add this to your `Gemfile`: ``` gem 'middleman-sprockets', '4.0.0' ``` You will also need to then make the following changes to your `config.rb`: ``` activate :sprockets after_configuration do Opal.paths.each do |p| sprockets.append_path p end end set :js_dir, 'app' # for instance if your ruby code is in /source/app ``` The huge thing I haven't figured out is source maps support. Anyone here know how to add opal source maps support to middleman? ---------------------------------------------------------------------------------------------------- [20:07:06] Mitch VanDuyn(@catmando):hmmm... I also had to do this in the top level js file `Opal.load('test')` (assuming I have a single ruby file called test) ---------------------------------------------------------------------------------------------------- [20:11:14] hayley(@hayley):yeah, sorry, the actual JS stuff was the *other* half of the instructions I didn't include. But yeah, as I understand it, as of 0.8 and greater, opal code does not auto-execute just because it got pulled in with sprockets (meaning you'd see its source in your compiled js file, but it wouldn't be running). This does give you the flexibility of not having to worry about what order sprockets pulls your files in, but then (if you're using a .js file as an entry point), you'll need to do `Opal.load('FILENAME')` to make sure it executes. ---------------------------------------------------------------------------------------------------- [20:22:04] Mitch VanDuyn(@catmando):yeah - great... with your old blog post, etc, I have it all working pretty nice... ---------------------------------------------------------------------------------------------------- [20:58:03] Mitch VanDuyn(@catmando):My plan is to have a separate ruby directory so you will have ``` source ├── images │   └── middleman-logo.svg ├── index.html.erb ├── javascripts │   ├── all.js │   └── some_js_code.js ├── layouts │   └── layout.erb ├── ruby │   ├── application.rb │   ├── components │   │   └── clock.rb │   └── ruby.rb └── stylesheets ├── _normalize.scss └── site.css.scss ``` ---------------------------------------------------------------------------------------------------- [20:58:50] Mitch VanDuyn(@catmando):BUT... that said I just discovered middleman-react, so I am off the play with that before going farther... ---------------------------------------------------------------------------------------------------- [21:06:25] hayley(@hayley):yeah, I have something similar with my v3 project. I have an opal directory with its own Gemfile and then a Rakefile that will build what's in the opal directory. Then I have a Procfile in the main middleman directory that runs middleman at the same time as the Rake rebuilder. What I want to do though is experiment with getting webpack going both for JS dependencies and building opal files, especially given that the middleman devs seem so intent on divorcing the project from sprockets and using the external pipeline instead (external pipeline is v4 only though). ---------------------------------------------------------------------------------------------------- [22:08:03] Forrest Chang(@fkchang): @Qudware we have a public facing app in production and several internal facing apps. ---------------------------------------------------------------------------------------------------- ############################## [2016-07-16] ############################## [17:48:41] Elia Schito(@elia):@hayley wrt jsonp I think jquery has support for it (via $.ajax options), otherwise you can still add functions to window: `require 'native'; $$[:callback_123] = -> data { p Hash.new(data) }` (don't trust this code 100%, didn't test it) ---------------------------------------------------------------------------------------------------- [19:06:21] hayley(@hayley):@elia I didn't even know that was a possibility until @catmando mentioned that he's apparently working on a reactrb extension for middleman. For me though, after many happy years with middleman, I am shopping around for a new static site generator for a lot of reasons, but one huge one being that there's a bug that prevents me from safely upgrading some of my sites to v4 (and middleman v3 is stuck on opal 0.7.x unless you add something outside of middleman to handle the transpiling). And yeah, jquery definitely has support for jsonp. And I'll have to look into your sample code. I vaguely remember writing some really hackish coffeescript/jquery thing that would send the jsonp data back to opal. ---------------------------------------------------------------------------------------------------- [19:32:29] Elia Schito(@elia):@hayley during the last update to the opal site I almost rewrote a subset of middleman using actionview, maybe that's a path worth exploring more. The greatest appeal middleman had for was its similarity with rails ---------------------------------------------------------------------------------------------------- [19:49:33] Mitch VanDuyn(@catmando):@elia I'm almost done with reactrb-middleman ---------------------------------------------------------------------------------------------------- [19:50:09] Mitch VanDuyn(@catmando):It includes reactrb, but will work with poo as well plain old opal ---------------------------------------------------------------------------------------------------- [19:51:29] Elia Schito(@elia):Nice! And LOLS for POO! ---------------------------------------------------------------------------------------------------- [22:09:31] hayley(@hayley):@elia I'm actually one of those 'unicorns' who calls Ruby their programming language of choice but doesn't actually know Rails so I know very little about actionview. @catmando PlainOldOpal. Hahaha. ---------------------------------------------------------------------------------------------------- [22:28:23] hayley(@hayley):Anyone with experience with opal-webpack, want to take a stab at something I'm attempting? I opened issue cj/opal-webpack#36 but I'm new to the webpack world, so I'm kinda lost as to where to go from here. In a sentence, I'm trying to integrate reactrb into the react.js-based static site generator gatsby. I just wrote up a bunch of instructions in the README: https://github.com/hayley/hayley.io I kinda feel that, given the direction I seem to be headed (writing SPAs), that a static site generator oriented towards doing exactly that kind of site would be the best fit for me going forward. But only if I can get proper opal/reactrb support. Love Opal. Can't stand JS. ---------------------------------------------------------------------------------------------------- [03:29:15] hayley(@hayley):hey, for those of you who are using Opal to hit json on 3rd party sites where they *don't* have `Access-Control-Allow-Origin: *`, how are you handling it? I've generally handled it by finding free proxies (e.g. https://crossorigin.me/) but they seem to disappear/crash quite frequently. And is there an official way to handle jsonp with opal? ---------------------------------------------------------------------------------------------------- [17:46:26] Elia Schito(@elia):@hayley not sure if it's worth it, but maybe creating a middleman-opal gem is easier than the blogpost :) ---------------------------------------------------------------------------------------------------- ############################## [2016-07-17] ############################## [03:43:13] Biarity(@Biarity):I posted a while back asking for feedback on Opal's state.

We're trying firebase + opal but still evaluating options. ---------------------------------------------------------------------------------------------------- ############################## [2016-07-18] ############################## [09:19:14] Guillaume Grossetie(@Mogztter):Hello ---------------------------------------------------------------------------------------------------- [09:19:58] Guillaume Grossetie(@Mogztter):I'm frequently hitting an error when running `mspec_ruby_nodejs`: `The rescue keyword parses 'a += b rescue c' as 'a += (b rescue c)' ERROR` ---------------------------------------------------------------------------------------------------- [09:20:57] Guillaume Grossetie(@Mogztter):does anyone have a clue about this error ? ---------------------------------------------------------------------------------------------------- [11:01:46] Ilya Bylich(@iliabylich):@Mogztter Are you getting this error on master? ---------------------------------------------------------------------------------------------------- [11:02:08] Ilya Bylich(@iliabylich):And do you run the full rubyspec test suite? ---------------------------------------------------------------------------------------------------- [15:10:59] Guillaume Grossetie(@Mogztter):@iliabylich yes and I'm running `bundle exec rake mspec_ruby_nodejs` ---------------------------------------------------------------------------------------------------- [22:44:23] Doug Orleans(@dougo):What's the status of adding `optparse` to stdlib? Has anyone started working on it? Is there any expectation that it wouldn't just run as-is from MRI source? ---------------------------------------------------------------------------------------------------- ############################## [2016-07-19] ############################## [17:06:45] Forrest Chang(@fkchang):So then I guess my thought of customers must be wrong? The rank and file (or even people of prominence) in the Ruby/Rails community largely don't care, so maybe I should stop trying to speak to that crowd. Why opal? For me, in 1 sentence, bringing the Joy of Ruby to everywhere that that Javascript exists. I guess it's still JDD (Joy driven development). I've been evolving towards that as my main message, maybe that's the unifying theme among "customers" ---------------------------------------------------------------------------------------------------- [18:34:25] Torsten Rüger(@dancinglightning):@fkchang just 2 cent: I guess you can count me in as one of the handful :-) (i would think it's more but to the point) I think the customer is a rails developer. And so the product should be well integrated into rails, and one that provides benefit. Ie does more than one can do without feeling the pain of coffee script, but without abandoning rails. It seems to me there is lots of experimenting with pure client going on, which is great for play, but no use in production. And very real efforts for frameworks (clearwater, volt) just miss the customer imho, ie lack integration. ---------------------------------------------------------------------------------------------------- [18:51:50] Torsten Rüger(@dancinglightning):@elia ok i had a look. Up to fazibear if he wants a table layout. ---------------------------------------------------------------------------------------------------- [19:28:53] Doug Orleans(@dougo):@iliabylich I was asking about optparse because it's used by Minitest, but opal-minitest has option handling disabled because of the lack of optparse in Opal. It uses phantomjs, not Node, but it's still a command-line use case. But, I just realized I could parse the command-line options in the Rake task (in plain Ruby), and pass them as a pre-parsed hash to Minitest inside Opal. ---------------------------------------------------------------------------------------------------- [19:30:04] Doug Orleans(@dougo):But tying this into @fkchang's topic, I think "Opal is mostly for browser" is maybe not the best stance to take. ---------------------------------------------------------------------------------------------------- [19:30:59] Doug Orleans(@dougo):or maybe it is... as long as that includes headless browsers. :) ---------------------------------------------------------------------------------------------------- [19:31:44] Doug Orleans(@dougo):I'll admit that the only reason I use opal-minitest is for unit testing my code that is intended to run in the browser. ---------------------------------------------------------------------------------------------------- [19:34:41] hayley(@hayley):@fkchang for me, the whole JDD is a big thing. Coffeescript was a decent improvement to the syntax, but I always missed the power of Ruby's standard library. Before, I switched to opal, I had started using http://sugarjs.com/ (which now seems abandoned), but it wasn't the same. I feel like half of my love of ruby is simply all of the useful things that are built-in to the language. I kinda mentioned this once on the reactrb channel, but maybe opal itself could use something like https://react.rocks/ - I know that site has been hugely influential about getting me inspired about react in general. awesome-opal is a great start, but for someone like me, the "gallery" style (screenshots, etc) is what I really like to see since you can get more of a feel of something from a screenshot than from a text description. ---------------------------------------------------------------------------------------------------- [19:55:13] Mitch VanDuyn(@catmando):https://docs.google.com/a/catprint.com/presentation/d/1TcUgYu5Od8Q6PH_P76j8fGiAKawpoootZXmWOpIL5jw/pub?start=true&loop=false&delayms=3000 ---------------------------------------------------------------------------------------------------- [19:56:49] Mitch VanDuyn(@catmando):My answer above... in 1 year we have reduced our code size by almost half, we have a much better UI, maintenance is easier, and we are not done yet... by end of year I expect this to be almost 100% ruby. ---------------------------------------------------------------------------------------------------- [19:57:16] hayley(@hayley):@catmando "You need permission to access this published document." :D ---------------------------------------------------------------------------------------------------- [19:57:27] Mitch VanDuyn(@catmando):rats... ---------------------------------------------------------------------------------------------------- [19:58:27] hayley(@hayley):As a shortcut, anytime I'm posting something where I feel permissions might be a problem, I try loading the page in Chrome's incognito mode to see what happens. ---------------------------------------------------------------------------------------------------- [20:08:54] Mitch VanDuyn(@catmando):https://slides.com/mitchvanduyn/deck-6/live ---------------------------------------------------------------------------------------------------- [20:09:21] Mitch VanDuyn(@catmando):try that :-) Thanks @hayley ---------------------------------------------------------------------------------------------------- [20:18:34] hayley(@hayley):@catmando Nice. I have a random thought just for the heck of it: how hard would it be to *show* the difference? Like, not just as a chart, but something along the line's of atom's minimap (which obfuscates the actual text too) where you'd concatenate the entire v3 and v4 codebases into two tiny images that you could show side by side. ---------------------------------------------------------------------------------------------------- [20:23:11] Mitch VanDuyn(@catmando):that chart is about as close as you are going to get to that... there are just to many file changes if I understand what you are suggesting ---------------------------------------------------------------------------------------------------- [20:28:58] hayley(@hayley):@catmando it's just kind of an out there idea to begin with, but if you were using git and could easily check out the last version of v3 versus what you have now, that's what I'd use... I might actually try to build a visualizer for myself if it doesn't already exist, but how I'm imagining it would work is that you'd point this image generator script at a project directory. And then it would go through and then produce one really long image à la atom's minimap (see the right side of the image in the screenshot on https://atom.io/packages/minimap). I don't know, I'm thinking this counts more so as "fun" than useful, but it could be interesting as a before/after comparison tool. ---------------------------------------------------------------------------------------------------- [20:36:22] Forrest Chang(@fkchang): @dancinglightning regardless of whether the rank and file Rails dev is the target audience, I definitely think that better Rails integration benefits, simply because most Rubyists, and I'm assuming most opalists use Rails, so there's a lot of JDD to be exploited there. ---------------------------------------------------------------------------------------------------- [20:38:49] Forrest Chang(@fkchang):@dougo I think a big thing for me is really "joy of Ruby everywhere there is JS", that's what is a big draw to reactrb (aside from the fact that react's component based framework is the 1st JS framework that sat well w/my way of thinking), is that if you can do reactrb (via react.js of course), then you can web, mobile (react native), and desktop (electron and friends), as well as some of the other fringe rendering platforms that react has reached (u can write terminal console apps w/react for example, flipboard made a react-canvas for performance, etc.) ---------------------------------------------------------------------------------------------------- [20:39:03] Forrest Chang(@fkchang):but there are other options because JS is literally everywhere ---------------------------------------------------------------------------------------------------- [20:40:02] Forrest Chang(@fkchang):@hayley a react rocks equivalent would be nice, not certain there is enough content yet for such, I guess the next best thing is the awesome-opal page ---------------------------------------------------------------------------------------------------- [20:43:58] Doug Orleans(@dougo):JS is everywhere, but Ruby is also most places too, so it's hard to see a case for Opal where MRI works just fine. ---------------------------------------------------------------------------------------------------- [20:44:57] Doug Orleans(@dougo):which is what I assume @iliabylich was getting at with "Opal is mostly for browser". ---------------------------------------------------------------------------------------------------- [20:45:42] meh.(@meh):dougo, yeah I don't get the point of running Opal on Node.js, other than helping with running tests or whatever ---------------------------------------------------------------------------------------------------- [20:46:23] Doug Orleans(@dougo):maybe if you need better threading, but then why not go to Elixir... ---------------------------------------------------------------------------------------------------- [20:47:22] Forrest Chang(@fkchang):@dougo in the case of reactrb, it's not just 1 language, but 1 way to write apps for desktop, web, mobile ---------------------------------------------------------------------------------------------------- [20:48:39] Doug Orleans(@dougo):sure, but that's basically the same as "for browser". it's just that the brower is also on desktop and mobile. ---------------------------------------------------------------------------------------------------- [20:48:56] Forrest Chang(@fkchang):u could do mri/jruby server, opal web, rubymotion ios, etc... but 1 language (sorta), and 3 ways (arguably still a diff in web front vs back, but reactrb lets you do server rendered views w/the same views you have on the front end, though opal lets u do that too w/erb and haml) ---------------------------------------------------------------------------------------------------- [20:50:04] Forrest Chang(@fkchang):node.js vs MRI, I don't have a compelling need for it at the time, but I could imagine that it might better if you wanted truly the same language on both sides vs close to the same langauge w/MRI and opal, and for the same perf reasons that ppl dropped MRI for node, would apply except that you can write ruby on node via opal ---------------------------------------------------------------------------------------------------- [20:51:42] Forrest Chang(@fkchang):JRuby brought "joy of ruby wherever the JVM is" for the most part, though I continue to see issues w/resources and start time. They continue to get better, but it affects the speed cycle, lessoning the JDD for me. Also, there are a number of gems which are neglected for JRuby. Still feels like JRuby and JRuby on Rails is a 2nd class citizen, despite JRuby being the most performant of Ruby implmentations ---------------------------------------------------------------------------------------------------- [20:51:46] meh.(@meh):dougo, but Node.js is not multi-threaded ---------------------------------------------------------------------------------------------------- [20:52:50] Doug Orleans(@dougo):good point :) ---------------------------------------------------------------------------------------------------- [20:52:55] Forrest Chang(@fkchang):It does seem that JS will have greater reach than the JVM, esp. in new horizons, for example IOT seems to be embracing JS, and you can dev for Windows 10 desktop and Mobile via js/HTML etc... ---------------------------------------------------------------------------------------------------- [20:53:20] Forrest Chang(@fkchang):I'm back to "Joy of Ruby everywhere JS is", in some cases, where better integrated the JDD is there ---------------------------------------------------------------------------------------------------- [20:54:18] Forrest Chang(@fkchang):Ride the JS train, after all, why not? ---------------------------------------------------------------------------------------------------- [20:54:44] Forrest Chang(@fkchang):@catmando I'm gonna tweet that slide ---------------------------------------------------------------------------------------------------- [20:54:53] Doug Orleans(@dougo):so far the MRI train still services most of the stops I want to visit :) ---------------------------------------------------------------------------------------------------- [21:00:14] Forrest Chang(@fkchang):@dougo no problem with that. I think similar to @hayley's notion of having something like react rocks, until a good example of how awesome it IS (vs could be), it'll be a hard sell. One of these days, I'll get one of my startup ideas up with an "all ruby stack" and then I can show it ---------------------------------------------------------------------------------------------------- [21:04:49] Mitch VanDuyn(@catmando):@fkchang yeah you should... ---------------------------------------------------------------------------------------------------- [21:04:54] Mitch VanDuyn(@catmando):I will on reactrb as well ---------------------------------------------------------------------------------------------------- [21:34:52] hayley(@hayley):re a react.rocks type of site, I'd actually be willing to come up with something at some point both opal/reactrb related (could be the same site and just filterable by specific technologies used), but I'd probably say my big concern is I don't want to get in a position where I feel like I'm stepping on toes. Like from watching some of the "awesome" lists and their pull requests, some of them are taking curation seriously and rejecting pull requests if they don't think something is awesome enough. Granted, that would be a problem with a text-only list: if it grows too large, it's hard to find the best of the best since there's zero filtering. Whereas a web page could kind of skirt around that via a voting/rating system or taking things like github stars into account. Personally, I feel like there shouldn't necessarily be curation (because likely every project is going to be of interest to someone), but obviously there needs to be a way for the most useful things to be easily findable. ---------------------------------------------------------------------------------------------------- [23:13:55] Mitch VanDuyn(@catmando):Seems like `rescue Exception => e` no longer has a backtrace on e... does anybody know why? ---------------------------------------------------------------------------------------------------- [23:35:51] Mitch VanDuyn(@catmando):NVM firefox issue (I guess) works fine in chrome as always... ---------------------------------------------------------------------------------------------------- [00:33:32] Ilya Bylich(@iliabylich):@dougo Opal doesn't have `optparse` (because Opal is mostly for browser). It could be used with Node but its implementation is quite complex - https://github.com/ruby/ruby/blob/trunk/lib/optparse.rb. I didn't check but I'm quite sure that Opal can't properly compile it. That code is quite complex, at least stuff like `do_something or return` and those ruby-specific regexpes are not completely supported by Opal yet. ---------------------------------------------------------------------------------------------------- [00:34:46] Ilya Bylich(@iliabylich):Probably it's possible to implement a minimal simplified subset of `optparse` ---------------------------------------------------------------------------------------------------- [00:35:52] Ilya Bylich(@iliabylich):I guess if you want to use it with Node you should use Node libraries ---------------------------------------------------------------------------------------------------- [05:33:04] Forrest Chang(@fkchang): ---------------------------------------------------------------------------------------------------- [11:28:14] Torsten Rüger(@dancinglightning):@elia Just saw the libraries compilation, great work! It says contribution and suggestions welcome at the bottom. If you make that a link or a mail, people might know where to put those suggestions. My suggestion would be to make a table or something, so the right column would be easier to scan. Another one would be to included liveliness, as that can be an issue with some of them. That would obviously only work if the list is generated. ---------------------------------------------------------------------------------------------------- [11:50:59] Mitch VanDuyn(@catmando):@qudware I don't know anything about firebase, let us know how it goes... ---------------------------------------------------------------------------------------------------- [12:35:40] Guillaume Grossetie(@Mogztter):@iliabylich I think this a "concurrent" issue. I can reproduce this issue when saving the whole javascript file produced. If I delete everything but "rescue_spec" then I get no error ---------------------------------------------------------------------------------------------------- [12:37:05] Ilya Bylich(@iliabylich):@Mogztter Then it can be some shared state between tests ---------------------------------------------------------------------------------------------------- [12:38:05] Ilya Bylich(@iliabylich):And you are the only one who can catch it :smile: ---------------------------------------------------------------------------------------------------- [12:38:06] Guillaume Grossetie(@Mogztter):@iliabylich indeed, I will dig a bit further and let you know ---------------------------------------------------------------------------------------------------- [12:38:25] Guillaume Grossetie(@Mogztter):lucky me :smile: ---------------------------------------------------------------------------------------------------- [12:44:56] Guillaume Grossetie(@Mogztter):seems like return_spec and rescue_spec are conflicting ---------------------------------------------------------------------------------------------------- [12:46:23] Guillaume Grossetie(@Mogztter):ScratchPad is a good suspect ---------------------------------------------------------------------------------------------------- [12:55:55] Guillaume Grossetie(@Mogztter):The compiled code is: ``` (a = $rb_plus(a, (function() { try { console.log("self.$b()", self.$b()); return self.$b() } catch ($err) { console.log("err", $err); if (Opal.rescue($err, [$scope.get('StandardError')])) { try { return c } finally { Opal.pop_exception() } } else { throw $err; } }})())); ``` When `return_spec` and `rescue_spec` are enabled, `self.$b() 1` ---------------------------------------------------------------------------------------------------- [12:56:43] Guillaume Grossetie(@Mogztter):But when `return_spec` is disabled, an exception is thrown and rescue is working ---------------------------------------------------------------------------------------------------- [12:57:10] Guillaume Grossetie(@Mogztter):so something is mocking `self.$b()` function in `return_spec` ---------------------------------------------------------------------------------------------------- [12:58:43] Guillaume Grossetie(@Mogztter):``` describe "downstream from a lambda" do it "returns to its own return-capturing lexical enclosure" do def a ->{ yield }.call return 2 end def b a { return 1 } end b.should == 1 end end ``` ---------------------------------------------------------------------------------------------------- [12:58:57] Guillaume Grossetie(@Mogztter):hm hm ---------------------------------------------------------------------------------------------------- [12:59:31] Ilya Bylich(@iliabylich):Yeah, it can be the issue ---------------------------------------------------------------------------------------------------- [13:00:16] Guillaume Grossetie(@Mogztter):but why am I the only one to reproduce this issue ? ---------------------------------------------------------------------------------------------------- [13:01:20] Guillaume Grossetie(@Mogztter):I can confirm that the full test suites is working for me if I comment out `downstream from a lambda` spec ---------------------------------------------------------------------------------------------------- [13:03:30] Ilya Bylich(@iliabylich):usually rubyspec uses `eval` to evaluate the code directly in the context of the current example ---------------------------------------------------------------------------------------------------- [13:03:32] Guillaume Grossetie(@Mogztter):we can also rename `b` function to something less generic. Do you know why "inner" functions is visible outside ? ---------------------------------------------------------------------------------------------------- [13:04:16] Ilya Bylich(@iliabylich):For me `rescue_spec` gets executed before `return_spec` ---------------------------------------------------------------------------------------------------- [13:04:23] Ilya Bylich(@iliabylich):That's why there's no conflict ---------------------------------------------------------------------------------------------------- [13:05:02] Guillaume Grossetie(@Mogztter):lol ---------------------------------------------------------------------------------------------------- [13:05:19] Ilya Bylich(@iliabylich):``` ruby proc do def m p 'm called' end end.call self.m ``` ---------------------------------------------------------------------------------------------------- [13:05:58] Ilya Bylich(@iliabylich):Because blocks are evaluates in the outer context ---------------------------------------------------------------------------------------------------- [13:06:10] Ilya Bylich(@iliabylich):And there's no `private` in opal ---------------------------------------------------------------------------------------------------- [13:06:19] Guillaume Grossetie(@Mogztter):got it ---------------------------------------------------------------------------------------------------- [13:07:49] Ilya Bylich(@iliabylich):Rubyspec defines method `:b` on the `Object` ---------------------------------------------------------------------------------------------------- [13:08:01] Ilya Bylich(@iliabylich):And it makes it available everywhere ---------------------------------------------------------------------------------------------------- [13:08:34] Guillaume Grossetie(@Mogztter):> For me `rescue_spec` gets executed before `return_spec` Even with a french locale, `return_spec` should come after `rescue_spec` if sorted by filenames :wink: ---------------------------------------------------------------------------------------------------- [13:09:30] Guillaume Grossetie(@Mogztter):but I guess we are not explicitly sorting files ---------------------------------------------------------------------------------------------------- [13:09:37] Ilya Bylich(@iliabylich):Could you check an output of `tmp/mspec_nodejs.rb`? ---------------------------------------------------------------------------------------------------- [13:10:02] Guillaume Grossetie(@Mogztter):I have one ---------------------------------------------------------------------------------------------------- [13:10:13] Ilya Bylich(@iliabylich):Yes, `testing.rake` has all the code for compiling rubyspec.

That's beyond my skill set :worried: ---------------------------------------------------------------------------------------------------- [14:49:22] Ilya Bylich(@iliabylich):This example shows the difference between explicit `def` and `def` in `evaluate`: ``` ruby describe "Description" do evaluate <<-ruby, "Test 1" do def m1 123 end ruby m1.should == 123 end it "Test 2" do def m2 456 end m2.should == 456 end it "Test 3" do lambda { self.m1 }.should raise_error(NoMethodError) lambda { self.m2 }.should_not raise_error(NoMethodError) end end ``` ---------------------------------------------------------------------------------------------------- [14:51:41] Ilya Bylich(@iliabylich):And it passes on MRI (didn't check on Opal yet). We need to modify rubyspec to have only examples like "Test 1". Tests like the second one are polluting global MSpec environment ---------------------------------------------------------------------------------------------------- [14:56:51] Guillaume Grossetie(@Mogztter):Yep I understand and you don't want to modify `ruby/spec` to surround every declarations with `evaluate` ---------------------------------------------------------------------------------------------------- [14:58:57] Guillaume Grossetie(@Mogztter):I read again your message ---------------------------------------------------------------------------------------------------- [14:59:18] Guillaume Grossetie(@Mogztter):you don't want to modify mspec runner ? ---------------------------------------------------------------------------------------------------- [14:59:36] Guillaume Grossetie(@Mogztter):to invoke test on a new `@env` object ? ---------------------------------------------------------------------------------------------------- [15:00:24] Guillaume Grossetie(@Mogztter):I can certainly add `evaluate` blocks on rubyspec :smile: ---------------------------------------------------------------------------------------------------- [15:01:38] Ilya Bylich(@iliabylich):Yes, we should replace every occurrence of explicit `def` in rubyspec to `evaluate("def ...", &block)` ---------------------------------------------------------------------------------------------------- [15:12:20] Ilya Bylich(@iliabylich):@Mogztter https://github.com/ruby/spec/issues/275 ---------------------------------------------------------------------------------------------------- [15:12:56] Guillaume Grossetie(@Mogztter):Thanks :+1: ---------------------------------------------------------------------------------------------------- [15:14:22] Guillaume Grossetie(@Mogztter):I'm experimenting with `evaluate`, but maybe the maintainer (@eregon ?) has a better idea ---------------------------------------------------------------------------------------------------- [16:07:33] Forrest Chang(@fkchang):@/all I have a weird bug working with opal 0.10.1.

Perhaps that's the wrong approach. In years of evangelizing, I've reached what, a handful of people? For myself, and I think I've been leaning that way for a while, maybe it's just "forget the rest of them, let's just make something 'insanely great' for my fellow opalists", but I suppose if we are to do a Steve Jobs approach, it' s not just focus on the product, but also the customers. ---------------------------------------------------------------------------------------------------- ############################## [2016-07-20] ############################## [03:32:21] Doug Orleans(@dougo):I finally dived in and made a fork of opal.

Later we should call `MSpec.files` - https://github.com/ruby/mspec/blob/master/lib/mspec/runner/mspec.rb#L48-L61 - which iterates over registered files, loads them one by one, and executes in a separate `@env`. I'll send a PR soon ---------------------------------------------------------------------------------------------------- [11:21:59] Ilya Bylich(@iliabylich):Probably we can even use the original MSpec's method that runs the whole test suite - `MSpec.process` - https://github.com/ruby/mspec/blob/master/lib/mspec/runner/mspec.rb#L42-L46 ---------------------------------------------------------------------------------------------------- [19:11:13] Mitch VanDuyn(@catmando):hey all, trying to get execjs to evaluate opal code for middleman prerendering.

It's all about delegation. ---------------------------------------------------------------------------------------------------- [23:30:49] Doug Orleans(@dougo):yes, but also what I said :) ---------------------------------------------------------------------------------------------------- [23:31:08] Doug Orleans(@dougo):but, thanks, I hadn't thought about that distinction also. ---------------------------------------------------------------------------------------------------- ############################## [2016-07-27] ############################## [22:31:34] Elia Schito(@elia):@fkchang http://dev.mikamai.com/post/99319315864/why-json-sucks-for-user-configuration :smile: although json is fine for communication ---------------------------------------------------------------------------------------------------- [22:32:58] Elia Schito(@elia):@fkchang this could be what you were looking for in terms of exposing methods to JS, be aware that you can't expose a method if u have an ivar with the same name https://github.com/opal/opal/blob/master/stdlib/native.rb#L597-L612 ---------------------------------------------------------------------------------------------------- ############################## [2016-07-28] ############################## [01:06:33] Doug Orleans(@dougo):Hm, just noticed that my Opal-generated js assets are not being uglified ---------------------------------------------------------------------------------------------------- [01:07:10] Doug Orleans(@dougo):I have this in my config/environments/production.rb: ` config.assets.js_compressor = :uglifier` ---------------------------------------------------------------------------------------------------- [01:07:31] Doug Orleans(@dougo):Is there something else I need to set? ---------------------------------------------------------------------------------------------------- [01:26:38] Doug Orleans(@dougo):oh, duh.

The problem is once the foo.rb.erb is expanded to foo.rb I can't get it to "reexpand" during the testing.... I have tried setting the rails cache to null_cache, deleteting cache/tmp/* etc, etc... ---------------------------------------------------------------------------------------------------- [16:34:22] Mitch VanDuyn(@catmando):note that the file being expanded is inside a gem... perhaps that makes a difference? ---------------------------------------------------------------------------------------------------- [17:23:06] Jamie Gaskins(@jgaskins):@CicholGricenchos You should be able to run it with `Opal.load('application')` in JS after your `" end File.open("#{OUTFOLDER}/webserver/#{INDEXFILE}", "w") do |f| a = File.open(HTMLTEMPLATE).read f.puts ERB.new(a).result end ``` ---------------------------------------------------------------------------------------------------- [18:06:20] Elia Schito(@elia):@bwl21 that should still work (and be kept) ---------------------------------------------------------------------------------------------------- [18:06:31] Bernhard Weichel(@bwl21):Thanks, I will give it a try these days.

Basically, nearly every interaction w/a JS API, will typically return (and take as parameters) JS objects, I know in various places we are smart about converting, say jquery's ajax functions where response.json gets converted, but there's too much manual doing that can get consistent, in response, you also need to remember to add to_n to Opal Hashes you pass in to JS apis too. I think there is a 90% solution out there where we don't have to convert, but pretty much treat a JS object as a limited hash in opal, w/o having to do conversions. My 2 day ago pain came from I was storing json data in an indexedb field, and I had to search that, I'm dealing with 1000's of entries, so I don't want to have a loop that has to convert things, so I wrote all the filtering stuff in JS, which as we all know is decidely less pleasurable than writing opal, and call that via x-strings. Possibly native wrapping or .JS could address it (though I can't use .JS coz the app I'm doing it on is 0.8), but it still feels a bit piecemeal -- i.e. developers have to remember to do it. Ultimately I think this affects uptake of opal, where people will think, "Hey, if I have to remember to convert to and from (and sometimes that's rather complex, I get that problem with > 1 level deep nested objects in hyper-react all the time), then I may as well just do it all in JS". May we have a new class JsObject, maybe introduce a literal that thing we can use to define them? I dunno On the implementation side, @elia @meh @iliabylich, @jeremyevans @jgaskins may have some ideas, I suspect I'm not alone in feeling this "impedance mismatch with the primary way of moving data in JS", @catmando and some of the other hyper-react folks might have some insights -- there are solutions, but they can be intricate and hard to debug, If I could just handle nested js objects as if they were Opal Hash (a likes) w/o converting, that would pretty much do it. Sorry to ramble. Want to get this thought out while the pain is still fresh ---------------------------------------------------------------------------------------------------- [17:23:55] meh.(@meh):fkchang, the problem is they're plain objects, we can't add methods to them, so they can't behave like hashes in any way ---------------------------------------------------------------------------------------------------- [17:28:22] Forrest Chang(@fkchang):@meh we can't add to the proto? (or there is no proto) ---------------------------------------------------------------------------------------------------- [17:29:08] meh.(@meh):fkchang, it depends on how the code of the library deals with the object ---------------------------------------------------------------------------------------------------- [17:30:53] Forrest Chang(@fkchang):off the cuff, I think, the 80% need is to support [] and []= from the opal side on the js object w/o converting it. Is that possible, and what ramifications would it have on libs? ---------------------------------------------------------------------------------------------------- [17:32:07] Forrest Chang(@fkchang):that and iteration, keys() and values() ---------------------------------------------------------------------------------------------------- [17:35:29] meh.(@meh):fkchang, if we add methods to the prototype then EVERY object will have that method, it would be the same as adding the method to `BasicObject` ---------------------------------------------------------------------------------------------------- [17:37:25] meh.(@meh):the best solution is to just use .JS ---------------------------------------------------------------------------------------------------- [17:38:50] meh.(@meh):fkchang, and even if it were, if for some reason the underlying code uses a for loop instead of Object.* the method will show up ---------------------------------------------------------------------------------------------------- [17:42:41] Forrest Chang(@fkchang):@meh what if we clone the proto and make a new one? Got a quick .JS alike functionality for older opal's? ---------------------------------------------------------------------------------------------------- [17:43:13] meh.(@meh):fkchang, it wouldn't be an object, if the underlying code checks the passed value is a raw object it won't work ---------------------------------------------------------------------------------------------------- [17:43:37] meh.(@meh):there's just no way to work around that at runtime as far as I know ---------------------------------------------------------------------------------------------------- [17:46:14] Forrest Chang(@fkchang):hmm, so maybe we make something that takes a block, in the block, we wrap the js object with something that translates the hash funtionality and sets the values on the js object? A little weird, but it would meet the need to be able to manipulate like a Hash, but leave it a pure JS object ---------------------------------------------------------------------------------------------------- [17:46:21] Forrest Chang(@fkchang):I'll have to play w/that idea ---------------------------------------------------------------------------------------------------- [17:47:02] Forrest Chang(@fkchang):of course, this forces us to use, and remember to use blocks when dealing w/JS objects, but it might help, though .JS might meet most of that ---------------------------------------------------------------------------------------------------- [17:47:10] Forrest Chang(@fkchang):too bad I can't use .JS on most of my stuff ---------------------------------------------------------------------------------------------------- [17:48:02] meh.(@meh):fkchang, that's effectively the same as calling `#to_n` at the end, you still have to change your code ---------------------------------------------------------------------------------------------------- [17:48:13] meh.(@meh):and remember to do it ---------------------------------------------------------------------------------------------------- [18:40:00] Forrest Chang(@fkchang):u do have to remember, but to_n only works on creating, but not accessing ---------------------------------------------------------------------------------------------------- [18:40:12] Forrest Chang(@fkchang):and I can't use .JS on the project that needs it right now ---------------------------------------------------------------------------------------------------- [18:40:58] meh.(@meh):fkchang, don't you just need to wrap the incoming object in another `Hash`? ---------------------------------------------------------------------------------------------------- [18:41:07] meh.(@meh):I don't remember what stuff was in 0.8 ---------------------------------------------------------------------------------------------------- [18:44:44] Forrest Chang(@fkchang):My case atm is that that I store an array of JS objects in an indexedDB column (or equivalent of such), I need to filter out by certain values in the js objects, so I realize as I'm describing this, that my block approach doesn't work for this very situation, mabye I can universally wrap recursively. Anyways, I had to write JS code to be able to filter out the stuff. JS makes me cry sometimes ---------------------------------------------------------------------------------------------------- [20:47:35] Jamie Gaskins(@jgaskins):@fkchang If you're storing Ruby objects in IDB, and you know the type of object it was in Ruby, for example a `Person`, you can do: ```ruby # people is the raw JS array pulled from IDB people.map do |js_person| `Object.assign(#{Person.allocate}, js_person)` end ``` This should give you the object exactly as it existed before you persisted it to IDB. This may also include the `object_id`, but you might be able to strip that out. ---------------------------------------------------------------------------------------------------- [21:14:52] Forrest Chang(@fkchang):@jgaskins that's an interesting piece of info, I had decided to store it as the native js array of objects I pulled over opal-jquery ajax request, instead of the converted response.json, so maybe this could be used instead of doing it all in js ---------------------------------------------------------------------------------------------------- [21:19:24] Jamie Gaskins(@jgaskins):I think I've got some code on my machine at home to wrap the basics of IDB in Ruby, but I stopped messing with it once I realized it stripped all the proto/constructor metadata from the objects. I suppose it's not the end of the world. I'll see if I can post a Bowser PR for it tonight. ---------------------------------------------------------------------------------------------------- [21:27:04] Forrest Chang(@fkchang):yeah, I figure it's still best to just store js objects in indexdb, i.e. json compatible data ---------------------------------------------------------------------------------------------------- [21:27:23] Forrest Chang(@fkchang):but I'd be curious as to your indexedDB wrapper details ---------------------------------------------------------------------------------------------------- [23:38:15] Mitch VanDuyn(@catmando):@/all has anybody got opal-rspec-rails working???

And I would not consider that `{a:1, b:2}.to_js` yields a proper Opal object. It yields a JS object. I don't think that to_n provides this at the moment. I observe somtimes traces of Opal methods in the result. I recently had the trouble when I tried to use neatjson.js. Eventually I ended up going via JSON to get a `clean`JS object. ```ruby outputjs = %x{neatjson(JSON.parse(JSON.stringify(#{object.to_n})), #{opts.to_n})} ``` ---------------------------------------------------------------------------------------------------- [13:51:21] Guillaume Grossetie(@Mogztter):I'm using this function in a wrapper API to convert from plain JSON to `Opal.hash`: https://github.com/asciidoctor/asciidoctor.js/blob/0866d3335699f728f0a9197f8f01c51ce92525cc/src/asciidoctor-core-api.js#L1-L6 ---------------------------------------------------------------------------------------------------- [13:51:37] Guillaume Grossetie(@Mogztter):```javascript var toHash = function (object) { if (object && !object.smap) { return Opal.hash(object); } return object; }; ``` ---------------------------------------------------------------------------------------------------- [13:53:22] Guillaume Grossetie(@Mogztter):```diff -var options = Opal.hash({attributes: 'icons=font@ data-uri!'}); +var options = {attributes: 'icons=font@ data-uri!'}; var doc = asciidoctor.load('== Test', options); ``` ---------------------------------------------------------------------------------------------------- [13:54:43] Guillaume Grossetie(@Mogztter):This is at best "syntactic sugar" but at least`Opal.hash` is hidden :smile: ---------------------------------------------------------------------------------------------------- [21:27:18] Elia Schito(@elia):@/all having a look at opal-rspec-rails right now ---------------------------------------------------------------------------------------------------- [21:28:15] Elia Schito(@elia):I fear it's yak-shaving time :D ---------------------------------------------------------------------------------------------------- [23:21:26] Elia Schito(@elia):@catmando @jgaskins just pushed some changes that should have fixed the regexp error ---------------------------------------------------------------------------------------------------- [23:21:55] Elia Schito(@elia):do you mainly use it from the browser or from the terminal? ---------------------------------------------------------------------------------------------------- [23:22:22] Mitch VanDuyn(@catmando):Both.

That way when you used the gems during development you would not get this big payload. Understand that in production it happens automatically. I just want to pre-minify it. Also it would get rid of this annoying massive amounts of source maps which we can't get rid of. Also it would make initial boot time quicker. Right now it takes about 30 seconds for the first boot of the server as it compiles all that stuff. ---------------------------------------------------------------------------------------------------- [23:13:42] Forrest Chang(@fkchang):@catmando I'm assuming you have source maps turned off? I would like the ability to download one big sourcemap file - they're handy, instead of the gazillion that come out ---------------------------------------------------------------------------------------------------- [23:15:18] Mitch VanDuyn(@catmando):yes I have them turned off, but it still seems to want to generate them (perhaps just not download them?) I'm not sure. Perhaps its not source maps at all, but just the initial compile time. Either case precompiling gems would be a big help speed wise. ---------------------------------------------------------------------------------------------------- ############################## [2017-03-21] ############################## [18:37:03] Forrest Chang(@fkchang): @catmando u should use opal_hot_reloader - load time is only large at the beginning and then it's near instantaneous.

So Postgres has a (fairly bare-bones) V8 environment, but with no libraries or any such. Is it practical to get simple, even minimal Ruby compiling to run in that environment? ---------------------------------------------------------------------------------------------------- ############################## [2017-04-20] ############################## [00:33:13] Guyren Howe(@gisborne):Many failings. ---------------------------------------------------------------------------------------------------- [00:39:22] Guyren Howe(@gisborne):I think the quoting is mucking up. Stand by. ---------------------------------------------------------------------------------------------------- [00:56:16] Guyren Howe(@gisborne):Trying now to define a function that returns Opal, by adding return Opal; at the end, I can define the function but when I try to run it, I get "Opal is not defined" on line 2063: Opal.loaded(["corelib/runtime"]); ---------------------------------------------------------------------------------------------------- [03:22:35] Guyren Howe(@gisborne):I don't think this is going to work. Let me put the idea into your heads, though. PLV8 already supports several transpiler options. It would be amazing if you brought this option to Postgres. ---------------------------------------------------------------------------------------------------- [13:01:40] Ilya Bylich(@iliabylich):@gisborne I've changed the code of `plv8` a little bit locally and got a `plopal` PG language (just like `plcoffee` for coffeescript) that almost works. It looks like: ``` sql CREATE EXTENSION plopal; DO LANGUAGE plopal $$ foo = %w(f o o).join `plv8.elog(INFO, foo)` $$; ``` But its performance is really bad. `plv8` uses a compiler (`coffee-script.js` / `opal-parser.js`) internally when you declare a PG function. It assumes that produced JS has no dependencies, it's true for CoffeScript/LiveScript (`plv8` has both of them embedded by default), but not for Opal. Opal is not just a transpiler, it has a runtime and a corelib, both of them must be included into the execution context. Maybe it's possible to optimize it by having 2 separated V8 contexts: one for compiling to js (must have a runtime + corelib + parser inside) and one for js evaluation (requires only runtime + corelib). But atm `plv8` doesn't expect an external compiler to have any runtime dependencies. Rewritting seems possible, but it requires a lot of time. ---------------------------------------------------------------------------------------------------- [14:36:02] Guyren Howe(@gisborne):You, my friend, whoever you are, are amazing. ---------------------------------------------------------------------------------------------------- [14:36:36] Guyren Howe(@gisborne):Possibly relevant: http://adpgtech.blogspot.com/2013/03/loading-useful-modules-in-plv8.html ---------------------------------------------------------------------------------------------------- ############################## [2017-04-21] ############################## [00:37:35] Guyren Howe(@gisborne):I also considered trying to glom together a function that returned the compiled text, as the Postgres function-defining mechanism ultimately takes the text of the function as a string. ---------------------------------------------------------------------------------------------------- [01:58:25] Guyren Howe(@gisborne):That failed also. 🙃 ---------------------------------------------------------------------------------------------------- [08:14:33] Elia Schito(@elia):@gisborne compiling once and storing the resulting js looks like a better approach as the compilation is very costly ---------------------------------------------------------------------------------------------------- [13:36:47] Guyren Howe(@gisborne):Certainly. ---------------------------------------------------------------------------------------------------- [20:20:25] Mitch VanDuyn(@catmando):@gisborne not sure if this is relevant to your project but the ruby-hyperloop project compiles ahead in three places: The hyperloop-config gem precompiles all opal gems, and the hyperloop-js (standalone hyperloop in the browser) precompiles and minimizes all the the hyperloop gems into a single js file. The hyper-console gem also precompiles the console code into a single JS file. So if we can help let us know over at https://gitter.im/ruby-hyperloop/chat site or private IM me... ---------------------------------------------------------------------------------------------------- [21:46:06] Guyren Howe(@gisborne):Thanks for that. I don't see a hyperloop-config gem, but I'm about to try the minimized compiler. ---------------------------------------------------------------------------------------------------- [22:22:50] Guyren Howe(@gisborne):Yeah, that still doesn't quite work. I tried to change it from global.Opal to plv8.global and was able to get it to define a function.

Been driving myself crazy for the past two days trying to figure out why I couldn't get stuff to precompile (a hyperloop project). The problem was traced down to `Rails.application.assets` was nil if `config.assets.precompile` is set to false. It seems a lot of stuff depends on that being there. ---------------------------------------------------------------------------------------------------- [19:50:16] Elia Schito(@elia):@adamcreekroad did you fix it somehow or is it still not working? Do you have steps or an app I can use to reproduce the problem? ---------------------------------------------------------------------------------------------------- [19:52:45] Adam(@adamcreekroad):@elia I had to revert back to sprockets-rails 2.3.3. All you need to do to reproduce is set `config.assets.precompile = false` in your environment and then do a `javascript_include_tag` and you should hit the problem. ---------------------------------------------------------------------------------------------------- [19:54:36] Elia Schito(@elia):thanks ---------------------------------------------------------------------------------------------------- [19:55:59] Adam(@adamcreekroad):no problem! ---------------------------------------------------------------------------------------------------- [19:56:40] Elia Schito(@elia):@adamcreekroad what's the point of setting precompile to nil? from what I see it starts as an array… ---------------------------------------------------------------------------------------------------- [19:57:41] Adam(@adamcreekroad):I'm sorry, I meant `config.assets.compile = false`.

What could be the reason? [![screenshot_867.jpg](https://files.gitter.im/opal/opal/kphD/thumb/screenshot_867.jpg)](https://files.gitter.im/opal/opal/kphD/screenshot_867.jpg) ---------------------------------------------------------------------------------------------------- [19:07:49] Bernhard Weichel(@bwl21):Does that mean, that whenver I pass a string to a native library, I should do it with .to_n ? ---------------------------------------------------------------------------------------------------- [19:22:59] Bernhard Weichel(@bwl21):I have copied parts of activesupport/lib/active_support/core_ext/object/deep_dup.rb , there is the root of the problem. I do a deep_dup on a hash, which makes the strings in that hash to bei String instead of JS primitives. ---------------------------------------------------------------------------------------------------- [19:27:37] Bernhard Weichel(@bwl21):The same happens with Numerical etc. ---------------------------------------------------------------------------------------------------- [19:33:19] Bernhard Weichel(@bwl21):deep_dup is defined in ```ruby class Object # Returns a deep copy of object if it's duplicable. If it's # not duplicable, returns +self+. # # object = Object.new # dup = object.deep_dup # dup.instance_variable_set(:@a, 1) # # object.instance_variable_defined?(:@a) # => false # dup.instance_variable_defined?(:@a) # => true def deep_dup duplicable? ? dup : self end end ``` ---------------------------------------------------------------------------------------------------- [19:36:18] Bernhard Weichel(@bwl21):where dupliactable? is something like ```ruby class Numeric # Numbers are not duplicable: # # 3.duplicable? # => false # 3.dup # => TypeError: can't dup Integer def duplicable? false end end ``` The problem went away after I added deep_dup to String and Numeric directly. But i don't not what I am doing. ```` ## this is necessary for opal ... class String def deep_dup self.to_n end end class Numeric def deep_dup self.to_n end end ``` Any advice is welcome. ---------------------------------------------------------------------------------------------------- [20:09:00] Jamie Gaskins(@jgaskins):[![Screen Shot 2017-05-29 at 4.06.27 PM.png](https://files.gitter.im/opal/opal/GNXm/thumb/Screen-Shot-2017-05-29-at-4.06.27-PM.png)](https://files.gitter.im/opal/opal/GNXm/Screen-Shot-2017-05-29-at-4.06.27-PM.png) ---------------------------------------------------------------------------------------------------- [20:09:08] Jamie Gaskins(@jgaskins):@bwl21 ^^ It's the difference between a string literal and `new String(string_literal)`. It's one of the quirks of JS — they even have a different `typeof`. ---------------------------------------------------------------------------------------------------- [20:10:37] Jamie Gaskins(@jgaskins):The same thing happens with numbers: `123` vs `new Number(123)`. I think it's some legacy stuff from when JS was originally intended to "work like Java". ---------------------------------------------------------------------------------------------------- [20:12:19] Jamie Gaskins(@jgaskins):If you call `.valueOf()` on it, it'll cast itself down to the primitive type, which might be why `.to_n` fixes it. ---------------------------------------------------------------------------------------------------- [20:16:19] Jamie Gaskins(@jgaskins):I ran into this same problem with Clearwater because it checks `typeof` before adding stuff to a DOM node. Some of the math stuff wasn't working because I was getting back objects instead of numbers — but only sometimes. I assume it's something in the bridging stuff between Ruby classes and JS primitives, but I didn't have time to look into it so I just ran everything through `.valueOf()`. ---------------------------------------------------------------------------------------------------- [20:36:19] Bernhard Weichel(@bwl21):@jgaskins do I get it right that I should for example change ```ruby `#{@native_jspdf}.text(#{nx}, #{ny}, #{text}, #{flags})` ``` to ```ruby `#{@native_jspdf}.text(#{nx}.valuelOf(), #{ny}.valueOf(), #{text}.valueOf(), #{flags}).valueOf()` ``` ---------------------------------------------------------------------------------------------------- [20:43:25] Bernhard Weichel(@bwl21):I basically have reimplemented one of my classes based on deep_merge, deep_dup etc. So I think I should find an implementation which does not require a change in the clients of that class.. I guess I stick with the `to_n` in the code I took from active_support untl I am facing another problem :-) Thanks ---------------------------------------------------------------------------------------------------- ############################## [2017-05-30] ############################## [03:18:43] Jamie Gaskins(@jgaskins):I think `to_n` should do the trick if it uses `valueOf()` under the hood — which it should if it doesn't already. ---------------------------------------------------------------------------------------------------- [05:07:42] Joseph McDonald(@jots_twitter):I put some code in: http://opalrb.org/try/# , pasted the output into newfile.js and tried: node newfile.js and get: `ReferenceError: Opal is not defined` do I need to do something special to run the output of `: http://opalrb.org/try/` in node? ---------------------------------------------------------------------------------------------------- [05:24:59] Joseph McDonald(@jots_twitter):I see I need to require code from `http://cdn.opalrb.org/opal/current/opal.js` at the top. that gets "hello world" working, but doesn't work with my test that tries to read ARGV to find out what files to open and process. ---------------------------------------------------------------------------------------------------- [18:14:39] Joseph McDonald(@jots_twitter):This is the code I wanted to try running under opal: https://github.com/timuckun/faster-command-line-tools-in-nim/blob/master/Ruby/csv_test.rb I guess there is something more needed to use ARGV and possibly File.open each_line? ---------------------------------------------------------------------------------------------------- ############################## [2017-06-11] ############################## [19:48:21] James Carlson(@jxxcarlson):An trying to use Opal in chrome.

` to `h('div', { id: 'foo' })` and ignores all other syntax, all you'd need is to define a `Kernel#h` method and it would just work. ---------------------------------------------------------------------------------------------------- [14:13:37] Billy.Zheng(@zw963):> @JikkuJose @fkchang I'm quite sure it can be done with some compiler plugin and abusing heredocs, e.g.: ``` class HelloMessage < React::Component def render <<-JSX
Hello {@props[:name]}
JSX end end ``` or some variant like `<<-HTML` which most editors will highlight as HTML: ``` <<-HTML
Hello {props.name}
HTML ``` Pray not do like this!! @Elia, Use HEREDOC is guly, and not `syntax highlight` + `code format` support, personal, i think this is a very bad idea. ---------------------------------------------------------------------------------------------------- ############################## [2017-07-13] ############################## [00:23:35] Forrest Chang(@fkchang):@JikkuJose I thought the original react.rb supported jsx, am I recalling wrong? ---------------------------------------------------------------------------------------------------- [00:24:23] Forrest Chang(@fkchang):anyways, I dunno if that will ppl over to react.rb, in my mind, the Ruby DSL is a selling point to Rubyists, since it's the full power of Ruby, but looks something like slim ---------------------------------------------------------------------------------------------------- ############################## [2017-07-17] ############################## [12:48:49] Billy.Zheng(@zw963):@elia , I just see [this](https://youtu.be/vhIrrlcWphU) Youtube video, ``Opal.rb - Elia Schito - wroc_love.rb 2016`` it is awesome!

React is an under layer that could be replace one day.

Once that is done I think we can release 0.11. My thought-process has been that many many projects use Opal-RSpec and releasing without proper support would be counterproductive.

I have a few details to finish - spent yesterday trying to figure out how to get a catch-all route in Rack (rails: `match '*all', to: 'home#page', via: [:get]`). We need all URLs to be resolved by the client side ReactRouter and Rack gives a 404). Solved this over night realizing that this is not a Rack problem as we will be deploying the site to Github pages so we would need to solve this somehow independently of Rack. Luckily I found this https://github.com/rafrex/spa-github-pages which will hopefully do the trick. I know that with Rack I can use a custom 404.html as well. If anyone is interested in this topic, please say, and I will send the link to the project and tutorial when it exists. ---------------------------------------------------------------------------------------------------- ############################## [2017-09-12] ############################## [13:00:50] Leon(@illogikal):yes please :) ---------------------------------------------------------------------------------------------------- [20:53:00] Colin Gunn(@balmoral):@barriehadfield very keen to see your tutorial on the rack + opal sprockets + hot reloader stack. 😀 ---------------------------------------------------------------------------------------------------- ############################## [2017-09-14] ############################## [16:24:38] Adrian Madrid(@aemadrid):@barriehadfield are you running all Hyperloop code (libs too) through Webpack?

Hope this useful to anyne building a non-rails app. Note that this is designed for Hyperloop but will work for any Opal based framework or Opal app (just ignore the Hyperloop steps) ---------------------------------------------------------------------------------------------------- ############################## [2017-10-03] ############################## [12:52:59] Frederic ZINGG(@fzingg):HI, When i run this code: ``` ``` I got the error: ``` Uncaught TypeError: item.$__id__ is not a function ``` How to access my Javascript object elements ? Thanks. ---------------------------------------------------------------------------------------------------- [12:56:30] Elia Schito(@elia):@fzingg you can either use the console: `require 'console'; $console.log @obj` ---------------------------------------------------------------------------------------------------- [12:58:06] Elia Schito(@elia):or import the objects as Hash instances: `require 'native'; puts @obj.map{|element| Hash.new(element)}` ---------------------------------------------------------------------------------------------------- [13:25:26] Frederic ZINGG(@fzingg):@elia Tx, the second one works well. ``` rubyobj = @obj.map{|element| Hash.new(element)} puts rubyobj[0][:name] ``` ---------------------------------------------------------------------------------------------------- ############################## [2017-10-05] ############################## [03:48:38] Andrew Havens(@andrewhavens):Hello everyone. I'm trying to find an example of how to load/compile a ".erb" file. I'm new to using Opal, but I have this idea that I want to try rendering an ".erb" file on both the server side and client side. ---------------------------------------------------------------------------------------------------- [03:50:23] Andrew Havens(@andrewhavens):I came across this example (https://github.com/opal/opal/blob/master/lib/opal/erb.rb) but I don't quite understand it. It looks like it's only intended for compiling at runtime, but I want to do the compiling from an actual file at build time. ---------------------------------------------------------------------------------------------------- [20:31:36] Elia Schito(@elia):@andrewhavens here's an usage example: ```plain $ cd /tmp $ opal -v Opal v0.11.0.rc1 $ echo "require 'bar'; puts Template['bar'].render(self)" > foo.rb /p/tmp $ echo "

<%= self.inspect %>

" > bar.opalerb $ opal -I. foo.rb

main

$ opal -I. foo.rb -c > foo.js $ tail -n 20 foo.js return output_buffer.$join();}, TMP_1.$$s = self, TMP_1.$$arity = 1, TMP_1)); }; /* Generated by Opal 0.11.0.rc1 */ (function(Opal) { var self = Opal.top, $nesting = [], nil = Opal.nil, $breaker = Opal.breaker, $slice = Opal.slice; Opal.add_stubs(['$require', '$puts', '$render', '$[]']); self.$require("bar"); return self.$puts(Opal.const_get_relative($nesting, 'Template')['$[]']("bar").$render(self)); })(Opal); /* Generated by Opal 0.11.0.rc1 */ (function(Opal) { var self = Opal.top, $nesting = [], nil = Opal.nil, $breaker = Opal.breaker, $slice = Opal.slice; Opal.add_stubs(['$exit']); return Opal.const_get_relative($nesting, 'Kernel').$exit() })(Opal); ``` ---------------------------------------------------------------------------------------------------- ############################## [2017-10-06] ############################## [15:34:03] Forrest Chang(@fkchang):@elia did you do the sourcemaps support? I was wondering if there's a way to customize which source maps get requested to the browser, I'd love to be able to cherry pick which source maps get loaded or even do it on demand ---------------------------------------------------------------------------------------------------- [17:28:21] Adrian Madrid(@aemadrid):anybody using `opal` with `brunch`? ---------------------------------------------------------------------------------------------------- [22:41:57] Elia Schito(@elia):@fkchang I did, at least in part, will provide all the support if you intend to work on that ---------------------------------------------------------------------------------------------------- ############################## [2017-10-08] ############################## [20:22:09] Forrest Chang(@fkchang):@elia if you know how that should work in general, I'd be willing to tackle that ---------------------------------------------------------------------------------------------------- ############################## [2017-10-09] ############################## [21:30:06] Elia Schito(@elia):@fkchang yes it works AFAICT, you were thinking about tackling it in sprockets or in some other system? ---------------------------------------------------------------------------------------------------- [21:32:26] Elia Schito(@elia):@fkchang probably the two places you want to start from are https://github.com/opal/opal-sprockets/blob/master/lib/opal/sprockets/source_map_server.rb and https://github.com/opal/opal/blob/master/lib/opal/simple_server.rb#L36-L38 ---------------------------------------------------------------------------------------------------- ############################## [2017-10-10] ############################## [16:33:36] Forrest Chang(@fkchang):@elia what I've been unable to figure out in the past is exactly what the browser server interactions should be, I'd like to write a tool that allow me to surpress source maps until I want them, and then cherry pick which ones to load, vs the "load the entire Ruby std lib, all your gems, one file at a time before the browser finishes your requests" behavior that currently happens ---------------------------------------------------------------------------------------------------- [17:01:59] Elia Schito(@elia):@fkchang being this the problem space I think would be valueable to research what other tools/compilers are doing since I fear that's more on the browser side of things. That said I think even a way to skip source maps for certain files (e.g. non user code like core+stdlib) would be useful to reduce noise and make load times faster. ---------------------------------------------------------------------------------------------------- ############################## [2017-10-11] ############################## [20:37:54] Mitch VanDuyn(@catmando):@/all dumb question. Does the opal compiler on the server (i.e. running as part of sprockets) run regular MRB ruby or is it running inside of a JS engine? ---------------------------------------------------------------------------------------------------- [20:53:57] Forrest Chang(@fkchang):whatever the server ruby is, MRI or Jruby ---------------------------------------------------------------------------------------------------- [21:01:56] Mitch VanDuyn(@catmando):okay... but just to be clear its not making the compilation be done inside of some JS engine right? We are trying to understand why it take sprockets 6 seconds to recompile just a few .rb files... ---------------------------------------------------------------------------------------------------- [22:08:45] Forrest Chang(@fkchang):I suspect that's more of an @elia question, though I'd guess Adam did most of that, opal compiler doesn't need JS to transpile opal to JS, not certain what the execjs requirement is for opal-rails, looking at the gemspec, I notice 2 things, 1) it's a development dependency so it's not required for deploy 2), most of the other development dependencies are to support testing, which require JS ---------------------------------------------------------------------------------------------------- [22:20:10] Elia Schito(@elia):@catmando the first thing you need to che is if the sprockets cache is working properly. Apart from that I guess could just be that Ruby is slow at this kind of code (compiling). On master the slowest part is the lexer, never checked for 0.10 but could easily be something similar. ---------------------------------------------------------------------------------------------------- [22:22:03] Elia Schito(@elia):Also if you happen to find the bottleneck and it is in fact optimizable I’m willing to do what I can to help as I see slow compilations at my workplace too ---------------------------------------------------------------------------------------------------- [22:47:32] Forrest Chang(@fkchang):wonder if we could port the compiler to crystal? ---------------------------------------------------------------------------------------------------- [22:52:10] Elia Schito(@elia):I was reading just yesterday an interesting pr with the parser (gem) reimplemented in c, it wasn’t merged but something like that despite the difficulty, would be very useful ---------------------------------------------------------------------------------------------------- ############################## [2017-10-12] ############################## [18:44:51] Jan Biedermann(@janbiedermann):great, thanks, i will try ---------------------------------------------------------------------------------------------------- [20:12:19] Adrian Madrid(@aemadrid):I can’t seem to get `Opal-Console` to work ---------------------------------------------------------------------------------------------------- [20:13:10] Adrian Madrid(@aemadrid):in the Chrome console I can get `Opal.RUBY_VERSION = “2.2.7”` but I get the `Opal not running or older than 0.7 - Console not supported for this page` in the `Opal-Console` ---------------------------------------------------------------------------------------------------- [21:22:59] Forrest Chang(@fkchang):@aemadrid it works, but there's something I need to fix with newer opal, ignore the message and type this in to handle a formatting bug ---------------------------------------------------------------------------------------------------- [21:23:10] Forrest Chang(@fkchang):```ruby OpalConsole.config.auto_pretty_print = false ``` ---------------------------------------------------------------------------------------------------- [21:23:33] Forrest Chang(@fkchang):@aemadrid I need to get around to fixing that ---------------------------------------------------------------------------------------------------- [22:06:13] Elia Schito(@elia):@janbiedermann @fkchang re windows: I think `RbConfig::CONFIG['host_os']` can have different values for mingw, cygwin, and other windows variants ---------------------------------------------------------------------------------------------------- [22:27:03] Adrian Madrid(@aemadrid):@fkchang that worked! I had to do it a couple times though because I was getting errors like `Exception: TypeError: Cannot read property '$==' of undefined` ---------------------------------------------------------------------------------------------------- [22:27:11] Adrian Madrid(@aemadrid):but doing it again usually solved that ---------------------------------------------------------------------------------------------------- [01:01:42] Colin Gunn(@balmoral):@/all Anyone know how to enable source maps with Roda opal assets? Might be an opal tilt option. ---------------------------------------------------------------------------------------------------- [02:17:00] Jamie Gaskins(@jgaskins):@balmoral Do you mean the `:assets` plugin that comes with Roda or the `roda-opal_assets` gem? ---------------------------------------------------------------------------------------------------- [02:19:13] Colin Gunn(@balmoral):@jgaskins yes - the `:assets` plugin provides `:js_opts` which get passed to `tilt`, but I’ve no idea where to start with that. I’ve tried `Opal::Config.source_map_enabled = true` before setting up the `Opal::Builder` and calling the plugin, but no luck. ---------------------------------------------------------------------------------------------------- [02:20:23] Colin Gunn(@balmoral):@jgaskins oh sorry - not not the `roda-opal_assets` gem, just straight usage of Roda for `roda-opal-example` ---------------------------------------------------------------------------------------------------- [02:21:07] Jamie Gaskins(@jgaskins):To be honest, I haven't had much success with the `:assets` plugin. I never got it to work with `require`. :-\ So it seems to be great if you load all your Opal dependencies and then all of your individual assets separately. ---------------------------------------------------------------------------------------------------- [02:22:21] Jamie Gaskins(@jgaskins):This might get you what you need, though https://github.com/clearwater-rb/roda-opal_assets ---------------------------------------------------------------------------------------------------- [02:26:15] Colin Gunn(@balmoral):`require` seems to work ok with my example. I’ve even moved some code out of `assets/js` and into a `lib` folder, with a stub `assets/js/main.rb` file which requires, say, `lib/client/app.rb`. And got `:dependencies` going so any file changes get past the caching. I’ll check out `roda-opal_assets` again. Thanks for you help. ---------------------------------------------------------------------------------------------------- [02:27:30] Jamie Gaskins(@jgaskins):Nice. I'd be happy to hear how you got that working some time :-) ---------------------------------------------------------------------------------------------------- [02:40:36] Colin Gunn(@balmoral):Very early days, but here’s what I’ve got so far: https://github.com/balmoral/roda-opal-example.git ---------------------------------------------------------------------------------------------------- [02:44:49] Colin Gunn(@balmoral):It would be nice to have a Roda plugin which handles opal/ruby explicitly. A bit beyond my pay grade at present :smile: ---------------------------------------------------------------------------------------------------- [06:29:34] Jan Biedermann(@janbiedermann):@catmando @elia @fkchang i would like to add some numbers to the performance issue: changing a file within a set 10 that is `require_tree 'component'` in rails sprockets: 6 seconds compiling that set of 10 files with Opal::Compiler from irb: 0.026 seconds Its NOT the compiler being slow. Now even if you add some file and cache checks to that 0.026 seconds, and maybe concatenate 3 megabytes of cached code -> 6 seconds is faaaar, faaaaaaaar awaahaay ... ---------------------------------------------------------------------------------------------------- [08:07:45] Elia Schito(@elia):@janbiedermann nice benchmark, did you try with Opal::Builder too? is `require 'opal'` part of the benchmark for the two cases? If the answer to the latter question is yes I think we should report it to the sprockets team… ---------------------------------------------------------------------------------------------------- [09:51:18] Jan Biedermann(@janbiedermann):@elia @catmando i just identified part of the problem, makes me wanno freak out, wtf?: in sprockets-3.7.1/lib/sprockets/uri_utils.rb, def split_file_uri(uri), commenting out this: ``` # Hack for parsing Windows "file:///C:/Users/IEUser" paths path.gsub!(/^\/([a-zA-Z]:)/, '\1'.freeze) ``` reduces load time (without compilation) from 3 to 1,5 seconds, i will report this for sure ---------------------------------------------------------------------------------------------------- [09:51:47] Elia Schito(@elia)::rocket: ---------------------------------------------------------------------------------------------------- [12:37:51] Jan Biedermann(@janbiedermann):@elia another issue is, that with opal, the entire ruby load_path becomes an asset load_path to, now sprockets walks all those directories looking for file changes, thousands of directories and files, with File.stat, which is slow. To make it fast, it should only check the files within the app for changes, maybe that would be the task for opal-rails or opal-sprockets to limit sprockets in that way, not sure how to achieve this. How can i achieve this? ---------------------------------------------------------------------------------------------------- [12:39:35] Elia Schito(@elia):@janbiedermann that's something that actually would help sprockets perfs for any project/compiler, I mean being able to make it stat files only in some dirs and consider other directories as "static". ---------------------------------------------------------------------------------------------------- [12:41:55] Jan Biedermann(@janbiedermann):alright, checking out sprockets ... ---------------------------------------------------------------------------------------------------- [12:42:17] Elia Schito(@elia)::turtle: :turtle: :turtle: :turtle: ---------------------------------------------------------------------------------------------------- [12:43:17] Elia Schito(@elia):@janbiedermann just to add some info, I think in rails 5 sprockets should rely on the file watcher to detect changes, not 100% sure tho ---------------------------------------------------------------------------------------------------- [13:59:28] Jan Biedermann(@janbiedermann):@elia @catmando, just to verify this sprockets thing i gorilla patched sprockets-3.7.1/lib/sprockets/path_utils.rb with ```ruby module PathUtils extend self def stat(path) root = '/put/rails/root/path/here/app' if (path[0..(root.size-1)] != root) @@gorilla_patch_cached_stats ||= {} return @@gorilla_patch_cached_stats[path] if @@gorilla_patch_cached_stats.has_key?(path) @@gorilla_patch_cached_stats[path] = if File.exist?(path) File.stat(path) else nil end else if File.exist?(path) File.stat(path) else nil end end end ``` Results: normal get of page with stock Sprockets 3.7.1: **4 seconds** with my 2 gorilla patches: ###483ms of which in sprockets 0.2s :) :rocket: on second page load ---------------------------------------------------------------------------------------------------- [14:40:15] Elia Schito(@elia)::bomb: :clap: ---------------------------------------------------------------------------------------------------- [14:45:54] Elia Schito(@elia):@janbiedermann I'm copying the patch to my current project right now :smile: ---------------------------------------------------------------------------------------------------- [14:47:05] Jan Biedermann(@janbiedermann):Please express your primal urge here: https://github.com/rails/sprockets/issues/504 ---------------------------------------------------------------------------------------------------- [15:01:20] Elia Schito(@elia):@janbiedermann any reason for this `if path[7..9].include?(':')` not being this `if path[9] == ':'`?

I don't see that performance issue with the `roda-opal_assets` gem, though. When I refresh, my app loads instantly no matter how many files it has, so I don't think Sprockets is the issue. ---------------------------------------------------------------------------------------------------- [18:19:09] Jan Biedermann(@janbiedermann):@jgaskins thats interesting, do you have a repo at hand? ---------------------------------------------------------------------------------------------------- [18:22:42] Jamie Gaskins(@jgaskins):@janbiedermann Sure https://github.com/jgaskins/clearwater_roda_example Clone it and run `./dev` to start it up ---------------------------------------------------------------------------------------------------- [18:22:58] Jan Biedermann(@janbiedermann):@jgaskins thanks ---------------------------------------------------------------------------------------------------- [18:27:23] Jamie Gaskins(@jgaskins):Part of it is that `roda-opal_assets` lets Sprockets use the browser's HTTP caching, but even if you Shift-Cmd-R to bypass the cache, it still loads very quickly. ---------------------------------------------------------------------------------------------------- [21:27:47] Jan Biedermann(@janbiedermann):https://github.com/rails/sprockets/pull/506, i believe it is sprockets ;) @jgaskins ---------------------------------------------------------------------------------------------------- [21:30:01] Jan Biedermann(@janbiedermann):thats the moderate version ---------------------------------------------------------------------------------------------------- [23:12:32] Jan Biedermann(@janbiedermann):https://github.com/rails/sprockets/pull/507, gorilla version, i still believe its sprockets ---------------------------------------------------------------------------------------------------- ############################## [2017-10-15] ############################## [04:04:49] Jamie Gaskins(@jgaskins):Weird. I don't understand why you and I would be seeing such different performance, then. ---------------------------------------------------------------------------------------------------- [04:35:53] Colin Gunn(@balmoral):Does anyone know of problems with condional requires using sprockets for testing RUBY_PLATFORM indirectly? I’m using a Platform module which goes like: ``` module Platform module_function def opal? RUBY_PLATFORM == 'opal' end def client? opal? end def server? !opal? end end ``` If I use this like ``` if Platform.client? require ‘client_code.rb’ else require ‘server_code.rb’ end ``` then opal sprockets loads `server_code.rb` when RUBY_PLATFORM is ‘opal’. If I use ``` if RUBY_PLATFORM == ‘opal' require ‘client_code.rb’ else require ‘server_code.rb’ end ``` it works ok. ---------------------------------------------------------------------------------------------------- [05:58:18] Jan Biedermann(@janbiedermann):@jgaskins for your clearwater_roda_example, the load_path is to small, to make a difference. increase load_path size, and loaded set, and sprockets will become a problem. You have just 6 load_paths to look things up, with rails and hyperloop there are hundreds of load paths and over 340 .rb files compiled. ---------------------------------------------------------------------------------------------------- [08:20:59] Colin Gunn(@balmoral):@jgaskins FYI I’ve given up on roda assets plugin (couldn’t get source maps going) and I’ve switched to roda-opal_assets type setup. I don’t much like putting my ruby code under assets/js so have structured it under lib/client, lib/common, lib/server... Thanks for a great example of how to pull all this stuff together. ---------------------------------------------------------------------------------------------------- [08:47:14] Torsten Rüger(@dancinglightning):@balmoral As far as i understood, the test for RUBY_PLATFORM is a compile time thing. Bit like #ifdef in the c days. So the compiler removes the appropriate require completely. If do the test in code (indirectly) both requires are included to be able to perform both branches at runtime. ---------------------------------------------------------------------------------------------------- [10:30:55] Jan Biedermann(@janbiedermann):@elia check current https://github.com/rails/sprockets/pull/506, sprockets uses an internal cache, hardcoded to 1024 entries, which is far to little for ruby-hyperloop or any other large opal-rails project. constant cache misses where the result, https://github.com/rails/sprockets/pull/506 now fixes this and gives me unbelieavable good numbers with opal, also for recompiles :) ---------------------------------------------------------------------------------------------------- [20:57:18] Elia Schito(@elia):@balmoral, @dancinglightning is right, that check is done at compilation level so the constant must be used explicitly, the only alternatives that comes to mind are: - to require the same filename but have different include paths for server & client, that can lead to some confusion - to keep the code as is and configure opal to ignore load errors (setting `dynamic_require_severity` to `ignore`), the con here is that you may miss some actual error in your app ---------------------------------------------------------------------------------------------------- [22:27:50] Elia Schito(@elia):@janbiedermann good catch! As a matter of fact our main app was hitting both the memstore (1024 entries) and the filestore limit (25MB) putting the latter under constant sprockets-GC pressure.

I just tried compiling ruby-hyperloop with opal 0.11. hyperloop brings a lot of code to compile for the client/browser/opal to get going, so this code has to be compiled at once after installing hyperloop and maybe again after changes to the gems and so on. hyperloop relies on sprockets, so sprockets, the opal processor will do the job. Some numbers: opal-0.10.5: ``` tc: 62.290000 7.360000 69.650000 ( 69.664902) tr: 2.750000 0.460000 3.210000 ( 3.173351) ts: 18.900000 30.560000 49.460000 ( 49.552422) ``` opal-0.11 ``` tc: 207.540000 10.260000 217.800000 (218.658982) tr: 4.320000 0.410000 4.730000 ( 4.778514) ts: 27.070000 37.370000 64.440000 ( 64.722876) ``` tc: time spent in the compiler tr: sprockets processing requires ts: caching source maps tc grew with 0.11 around 3 times. Are there any ideas how to make the processor/compiler faster, that where just not implemented yet? Or can i change some compiler setting? Or how can i make this process faster? ---------------------------------------------------------------------------------------------------- [10:33:47] Jan Biedermann(@janbiedermann):numbers are for compiling ~350 files ---------------------------------------------------------------------------------------------------- [10:37:44] Elia Schito(@elia):@janbiedermann the compiler of 0.11 relies on the "parser" gem, which is much more complete, but also does more work, I think would be interesting to see how much of compiler time is spent in parsing, I don't think any compiling option affects compile time (usually the effects are at runtime) except maybe for generating source maps… ---------------------------------------------------------------------------------------------------- [10:38:30] Jan Biedermann(@janbiedermann):ok, i will check that :) parser ---------------------------------------------------------------------------------------------------- [10:41:05] Elia Schito(@elia):@janbiedermann just the other day I was looking at a PR to parser by @alexdowad for a C implementation of its bottleneck that was finally turned down for a number of reasons ---------------------------------------------------------------------------------------------------- [10:42:47] Jan Biedermann(@janbiedermann):interesting, i will look for that, thanks ---------------------------------------------------------------------------------------------------- [16:29:04] Jan Biedermann(@janbiedermann):@elia confirmed, ~85% of the time are spent in Parser::Base.parse ---------------------------------------------------------------------------------------------------- ############################## [2017-10-25] ############################## [17:54:19] Mitch VanDuyn(@catmando):@elia (or anybody else :-) is there any way to run a specific test (or at least a test file) in opal-rspec. ---------------------------------------------------------------------------------------------------- [17:55:01] Mitch VanDuyn(@catmando):I am following current instructions for browser, i.e. running rackup, then browsing localhost:9292 which all works fine, but I have a single test failing.

Any tips on where that `block` method might be would be appreciated, and I will get a PR done asap. ---------------------------------------------------------------------------------------------------- [06:51:39] LeoDaoTao(@LeoDaoTao):I’ve been experimenting with opal-rails today and I really like the way it handles jQuery. I’ve tried a few jQuery plugins that I use in some of my projects and all just work fine once I expose the methods. I’m having an issue with one of them — jCanvas. I expose the method I’m using (just trying the example from jCanvas homepage), but it does not work and there is no error, it just does not draw on the canvas. If I use JS in the console it works as expected so everything is loaded correctly. Maybe an issue with the way canvas works but I’m not sure. Any ideas on how can even start troubleshooing this? Hard to troubleshoot if you don’t get errors :-) ---------------------------------------------------------------------------------------------------- [06:53:50] Barrie Hadfield(@barriehadfield):@LeoDaoTao try `.to_n` if you are passing an array to a JS method ---------------------------------------------------------------------------------------------------- [06:58:26] LeoDaoTao(@LeoDaoTao):@barriehadfield I’m passing a hash and .to_n did the trick ---------------------------------------------------------------------------------------------------- [06:59:19] LeoDaoTao(@LeoDaoTao):@barriehadfield Thank you! ---------------------------------------------------------------------------------------------------- [07:10:12] LeoDaoTao(@LeoDaoTao):@barriehadfield I’m wondering if this maybe should be done by Opal internally? Are there any cases where .to_n would not be used? ---------------------------------------------------------------------------------------------------- [07:31:49] Elia Schito(@elia):@leodaotao Despite the similar syntax and usage js objects and hashes have major differences, I thought a couple of times about introducing a special syntax or method to produce js objects directly (eg `JS{foo: :bar}`) but never went much further ---------------------------------------------------------------------------------------------------- [07:33:20] LeoDaoTao(@LeoDaoTao):@elia yeah, just realized that after looking up JS docs, JS is not my strong point ---------------------------------------------------------------------------------------------------- [07:39:00] LeoDaoTao(@LeoDaoTao):@elia @barriehadfield so let’s say I have jQuery code that looks like this: ``` $('canvas').drawPolygon({ x: 100, y: 100, radius: 50, click: function(layer) { $(this).animateLayer(layer, { rotate: '+=144' }); } }); ``` How do I get the function passed to click: to work with opal ? ---------------------------------------------------------------------------------------------------- [08:47:38] Elia Schito(@elia):@LeoDaoTao I think it would be something like: ``` Element['canvas'].drawPolygon({ x: 100, y: 100, radius: 50, click: -> (layer) { Element[`this`].animateLayer(layer, { rotate: '+=144' }.to_n); } }.to_n) ``` Note that inside the lamda `self` comes from the lambda definition, that's why we need to explicitly reference `this` in backticks ---------------------------------------------------------------------------------------------------- [22:24:06] LeoDaoTao(@LeoDaoTao):@elia Thank you, I get a `Uncaught TypeError: self.$to_a is not a function` on the click event what could be causing this? ---------------------------------------------------------------------------------------------------- [22:25:43] Elia Schito(@elia):@LeoDaoTao you have to inspect the stacktrace in order to find the cause ---------------------------------------------------------------------------------------------------- [22:27:25] LeoDaoTao(@LeoDaoTao):@elie not sure I understand the error though, let me try to disect it more :-) ---------------------------------------------------------------------------------------------------- [22:34:36] LeoDaoTao(@LeoDaoTao):@elie I’m thinking of using a different canvas library though. jCanvas creates too much spaghetti code that looks bad even when written in ruby. I tried fabric.js which is pure JS and it works with objects. Translates to ruby objecs pretty nicelly when wrapped in Native. I think I’ll just wrap parts of it that I need. Very nice work you guys did with Opal. It’s really impressive! ---------------------------------------------------------------------------------------------------- ############################## [2017-10-27] ############################## [01:13:56] Forrest Chang(@fkchang):@elia the JS object direct syntax is something I would be interested in, but I'd have to think through all the ramifications ---------------------------------------------------------------------------------------------------- [12:17:22] Jan Biedermann(@janbiedermann):@elia the compile performance problem i mentioned before, opal 0.11 being 3 times slower, well, its not. The new parser of 0.11 uses method_missing a lot, when method_missing got overwritten by something not that fast, that will have a very negative effect on compile times. Thats what happened. ---------------------------------------------------------------------------------------------------- [13:44:26] Elia Schito(@elia):@janbiedermann interesting! you have any pointers in the code? I'd like to understand what's going on in a more tangible way ---------------------------------------------------------------------------------------------------- [14:15:00] Jan Biedermann(@janbiedermann):yes, i used stackprof gem to profile the compilation from within the opal-sprockets processor. method_missing is called a lot at the end of the process, but the trace doesn't give more detail than Opal::Compiler#compile here, and during parsing, its called most of the time from lib/parser/lexer.rb#advance. You can see the most dramatic effect by compiling this lexer.rb from within sprockets. This file compiled manually takes ~4s, in sprockets it took ~190s, without method_missng overwritten this file still takes much longer to compile. The time used then within Parser::AST::Node#assign_properties. I don't understand yet whats different there to the "manual" compile. ---------------------------------------------------------------------------------------------------- [14:17:29] Jan Biedermann(@janbiedermann):maybe i need to increase the stackprof resolution there. ---------------------------------------------------------------------------------------------------- [15:04:54] Elia Schito(@elia):@iliabylich see above, maybe you have some more insight into this ---------------------------------------------------------------------------------------------------- [19:07:32] Jan Biedermann(@janbiedermann):Another 0.11 issue, an out of place top level constant: ``` undefined method `component_did_mount' for class `String::Hyperloop::Component::Mixin' ``` The odd thing here being the `String` This does not happen on 0.10.5, but on 0.11 master. I followed it in the debugger, `$parent()` `$$parent` for Hyperloop look fine, this String comes from $$base_module, this gets set when a modules is loaded. What stopped me here is, this Hyperloop::Whatever::Something appears on to many places. How can i find the cause of this? ---------------------------------------------------------------------------------------------------- [23:12:22] Jan Biedermann(@janbiedermann):@elia @iliabylich the thing that was causing this performance problems really was that const missing. The other issue, for the remaining performance problem, has been an issue with my environment. I fixed that. Sorry if caused trouble. All works fine now and beautifully fast. ---------------------------------------------------------------------------------------------------- ############################## [2017-10-28] ############################## [09:19:03] Elia Schito(@elia):@janbiedermann looks related to constant lookup, if given a repro of any kind I can try looking into it (or give directions for anyone wanting to try) ---------------------------------------------------------------------------------------------------- [12:43:26] Jesus Castello(@matugm):Hi :) ---------------------------------------------------------------------------------------------------- [12:43:58] Jesus Castello(@matugm):Would Opal be a good solution for evaluating code on a "interactive coding exercises" kind of site? ---------------------------------------------------------------------------------------------------- [12:44:22] Jesus Castello(@matugm):Instead of evaluating the code on the server & having to sandbox everything. ---------------------------------------------------------------------------------------------------- [19:43:52] Xavier Riley(@xavriley):Hi :wave: I'm hoping to use Opal to implement a subset of Sonic Pi (a Ruby based live coding music environment http://sonic-pi.net/) in the browser with web audio. Most of that should be straightforward but a key part of that API is how it uses multiple threads with calls to `sleep`. While I don't have threads in JS, I can approximate a non-blocking sleep with the following: ``` function sleep(ms) { return new Promise(resolve => setTimeout(resolve, ms)); } async function kick() { console.log("boom") await sleep(1000); } async function hihats() { console.log("tick") await sleep(500); console.log("tick") await sleep(500); } // viewing the console shows these execute concurrently kick(); hihats(); ``` In terms of porting to Opal, I had the following idea. If a class is bridged from an `AsyncFunction`, the parser could check for ``` (async function(){}).constructor.name === "AsyncFunction" ``` and add the `async` keyword in front of the function call for generated methods. That would allow for something like the following: ``` %x{ var async_bridge_class_demo = Object.getPrototypeOf(async function(){}).constructor; async_bridge_class_demo.prototype.$sleep = function sleep(ms) { return new Promise(resolve => setTimeout(resolve, ms)); }; } class BridgeFoo < `async_bridge_class_demo` def self.baz puts "in block" `await #{sleep(2000)}` puts "still in block" end end BridgeFoo.baz ``` At the moment this fails because the `await` keyword is placed inside a non-async generated function. Firstly, does this seem like a reasonable approach? Secondly, is this the kind of thing that I'd use a rewriter for? Ideally I'd like to be able to make the `await` implicit so that `sleep(2000)` doesn't have to be placed in backticks but I can't think of a better way at present. ---------------------------------------------------------------------------------------------------- [20:41:18] Xavier Riley(@xavriley):sorry for the noise - I'm still reading up.

When I use .addEventListener(:keydown) { |event| handle_name_change(event) }, the event is not wrapped in, and I get this error: Uncaught TypeError: event.$target is not a function Can I get opal to wrap the event, or am I doing things the wrong way? --- Issue 2. All JS is executed 3 times for some reason, and I do not know why. Can you help, or guess? --- Here's the repo: https://github.com/rangeoshun/wromoror The files in hand is /app/assets/javascripts/setup.js.rb ---------------------------------------------------------------------------------------------------- [16:51:38] rangeoshun(@rangeoshun):Updated my question, thanks, and cheers! ---------------------------------------------------------------------------------------------------- [17:00:07] rangeoshun(@rangeoshun):Adding: in the handle_name_change method I try to read the event.target.value. ---------------------------------------------------------------------------------------------------- [17:32:18] rangeoshun(@rangeoshun):Issue 2 might be a turbolinks problem I think. ---------------------------------------------------------------------------------------------------- [21:09:01] rangeoshun(@rangeoshun):Ok, I switched to the Element.find("selector").on { |ev| ... } But still find strange, that the native way does not work as one would expect. ---------------------------------------------------------------------------------------------------- ############################## [2017-12-01] ############################## [04:49:59] Jamie Gaskins(@jgaskins):It's because method calls in Opal are prefixed with `$` to keep them from being ambiguous with instance variables in the compiled JS code. So calling `e.target.addEventListener(:foo) { |e| handle(e) }` in Ruby calls something like this: `e.$target().$addEventListener('foo')` with the block attached to the method itself as a property of its underlying function. ---------------------------------------------------------------------------------------------------- [06:29:28] rangeoshun(@rangeoshun):Hey! Thanks for your answer. Thing is, I get that almost all objects are wrapped in with `$` to keep separated from the native JS. The problem is, that if I attach a native event listener, I cannot use the resulting event, because the event object is not wrapped in an opal container, but my code is. That results in my compiled code is trying to access: `event.$target`, but my handler receives as`{ target: div }`this mechanism breaks the native event handler basically. ---------------------------------------------------------------------------------------------------- [11:02:17] rangeoshun(@rangeoshun):Did you guys come accross this issue with `opal-rails`? https://github.com/opal/opal-rails/issues/98 ---------------------------------------------------------------------------------------------------- ############################## [2017-12-02] ############################## [12:07:54] Bernhard Weichel(@bwl21):I try to build a CLI version of my app. Thereby I have problems with the 3rd party javascript libraries. They create classes or objects in a whatever namespace. Sometimes it is in an object called `exports` (when running in node), sometimes it is in the top level object (when running in Browser) What is the right way to implement a ruby module which works in Browser as well as in a node cli script. One of it uses the pattern neatjson_js.js: ```javascript (function(exports){ exports.neatJSON = neatJSON; function neatJSON(value,opts){ // some code here } neatJSON.version = "0.8.3"; })(typeof exports === 'undefined' ? this : exports); ``` in Opal I use this ```ruby if (RUBY_ENGINE == 'opal') require 'json' module JSON require 'neatjson_js' # desperatley try to find neatJSON as method. $neatJSON = %x{exports.neatJSON} rescue %x{neatJSON} def self.neat_generate(object, opts={explicit_sort: []}) outputjs = %x{#{$neatJSON}(#{object.to_n})), #{opts.to_n})}; outputjs end end end ``` ---------------------------------------------------------------------------------------------------- ############################## [2017-12-03] ############################## [22:16:31] Elia Schito(@elia):@rangeoshun saw the issue, thanks for the example app ---------------------------------------------------------------------------------------------------- [22:19:36] Elia Schito(@elia):@bwl21 try experimenting with `node_require` from stdlib `nodejs/kernel` https://github.com/opal/opal/blob/66849b5da5c54236eea5a0e5eaf95ba06a744fe3/stdlib/nodejs/kernel.rb#L19-L21 and let me know how it goes ---------------------------------------------------------------------------------------------------- ############################## [2017-12-04] ############################## [09:53:33] Bernhard Weichel(@bwl21):@elia I got "undefined method `node_require' for JSON" with opal 0.9.0 I then updated to opal 0.10.5 and got "undefined method `node_require' for JSON" as well. but with 0.10.5 I also got a runtime error ``` opal-neatjson.self.js?body=1:16 Uncaught ReferenceError: exports is not defined at opal-neatjson.self.js?body=1:16 at opal-neatjson.self.js?body=1:19 at Opal.modules.opal-neatjson (opal-neatjson.self.js?body=1:36) at Object.Opal.load (runtime.self.js?body=1:1957) at Object_alloc.Opal.require [as $require] (runtime.self.js?body=1:1981) at Opal.modules.application (application.self.js?body=1:9) at Object.Opal.load (runtime.self.js?body=1:1957) at (index):135 ``` The compiiled part is ```javascript $gvars.neatJSON = (function() { try {return exports.neatJSON; } catch ($err) { <--- if fails here if (Opal.rescue($err, [$scope.get('StandardError')])) { return neatJSON; } else { throw $err; } }})(); ``` It seems that the error handling was changed somehow.
