13:14 <godd2> Is it possible to get source maps working for static applications?

13:20 <godd2> Nevermind, I think I found my answer: "Opal::Environment is a bit lower level and doesn't support source maps by itself."

16:03 <godd2> If Opal::Environment is getting deprecated, what's going to be the way to make static applications?

17:57 <adambeynon_> godd2: hey

17:57 <adambeynon_> Opal::Environment is just a subclass of Sprockets::Environment

17:57 <adambeynon_> so in future all you need to do is add each path from Opal.paths() into a sprockets instance

17:57 <adambeynon_> thats all Opal::Environment does

17:57 <adambeynon_> so, opal-rails does this automatically for you

17:58 <adambeynon_> so if youre using sinatra, for example, then you just need to do the same

17:58 <adambeynon_> I found that in reality, we were always dealing with an existing sprockets instance, so having our own was just confusing/in the way

18:05 <godd2> oh, okay, awesome!

18:08 <godd2> in that case, you can ignore my tweet

18:24 <elia> godd2, you can use the builder to generate both the js and map files

18:24 <godd2> Okay so this works. Is this what you had in mind? https://gist.github.com/nicklink483/45d700b91b2b1ab22e74

18:24 <elia> sure, that works too

18:27 <elia> godd2, to get the map you can do the following Opal::Processor.source_map_register['opaltest.js']

18:27 <elia> errata corrige: Opal::Processor.source_map_register['opaltest']

18:28 <elia> godd2, then the result needs to be converted to json before writing it to disk

18:28 <elia> (with .to_json)

18:29 <elia> adambeynon_, you around?

18:30 <adambeynon_> elia: hey. Yeah briefly.

18:31 <elia> adambeynon_, just wanted to know if I can rebase the cache branch on master

18:31 <elia> just to keep it fresh

18:32 <godd2> elia I'm trying all that out now. I'll let you know when I get snagged

18:32 <elia> godd2, good, I'll leave in a few moments, but I'll check the logs

18:32 <godd2> sounds good. Thank you very much

20:01 <godd2> Alright I got the standalone stuff working, but I'm having trouble understanding elia's instructions on source maps.

20:01 <godd2> Here's the proof-of-concept in a gist: https://gist.github.com/nicklink483/45d700b91b2b1ab22e74

20:02 <godd2> you can see in the Rakefile the explanation of the problem. Did he mean to run to_json on the result of Opal::Processor.source_map_register ? or of Opal::Processor.source_map_register['opal_test'] ? Or something else?

21:42 <adambeynon_> godd2: yes, so somthing like this (from your example):

21:42 <adambeynon_> out << Opal::Processor.source_map_register['opal_test’].to_json

21:43 <adambeynon_> Opal::Processor.source_map_register['opal_test’] returns just an instance of SourceMap::Map, so to_json gets it ready for the browser

21:48 <godd2> Opal::Processor.source_map_register['opal_test'].class in pry says its a String

21:51 <godd2> For the record, I'm using 0.7.0beta3 in ruby 1.9.3 on windows if that makes a difference

21:53 <adambeynon_> godd2: let me check

21:54 <adambeynon_> godd2: sorry, you are correct

21:54 <adambeynon_> yes, so, it should work as per your gist example

21:55 <godd2> okay perfect. so what do I do with that map file? I see it loads under the Network tab of Chrome developer tools
