asset pipeline precompile #1966

Closed epipheus closed 5 years ago

epipheus commented 5 years ago

I am in the middle of Opal hell. I could not figure out what was happening. In the end, it turns out that a bunch of opal is being culled out by a Proc I use to determine which items should be precompiled and which should not. As a result, Opal call just don't happen. Is there a simple way to determine what should be included and precompile and what should not?

These are the 247 files that are excluded from being precompiled

Here is my Proc. Not terribly pretty, but my attempt to smartly precompile items. Blacklisted items are overridden with whitelist items unless it's on the redlist. Yeah. I know. Refactoring is coming. 

Rails.application.config.assets.precompile << Proc.new { |path|

        full_path = Rails.application.assets.resolve(path)

    whitelist = [

    redlist = [
            /LICENSE/

    # puts "path: #{path}\n" if PMODE == :verbose # full_path breaks in production
    if (path =~ /(^[^_\/]|\/[^_])[^\/]*$/) and

I tried this Proc with the Opal hello world example, until I got it to this current regex set, it did not work. Now the hello world example works with this set but my production app doesn't sigh. Again if I am overlooking some "normal" way of doing this, I could really use insight.

@epipheus was trying to understand the problem, I'm not sure why you want to precompile that much stuff, isn't something as simple as this enough?

Rails.application.config.assets.precompile << lambda do |filename, path|
  next false if File.extname(filename).empty?
  path =~ %r{app/assets} && File.basename(filename) == 'application'
end

if you have an application.js.rb and require stuff from that it will be sprockets' job to mix all the sources together and compile the top file with everything.

Am I missing something?

epipheus commented 5 years ago

Ummm yeah... face palm -- so, I'm just being stupid and didn't realized that somehow I had commented out including application.js.rb in the view.

sigh this is awkward. Closing. Sorry.

no worries, simple mistakes are the best ones, super easy to fix! 👍

I will give that a try, usually I only see my gemified ui assets being compiled and I use the blacklist to eliminate partials that aren't well-formed on their own and crash precompilation. I'm trying to move all js in this app to opal and somehow in that process this proc pulls in all .rb files from opal/opal as if they are .js files.
