Add ability to have hooks inisde application.js and application.css via asset pipeline
I'm not sure if this is a good idea or not, and I'm not sure anyone except maybe JP Lang would know the best course of action.
There are already some discussions about this topic
And there are already some efforts
Move existing application.js contents to some other file like base.js and include it via asset pipeline and enable plugins to add their own js to application.js as a manifest which would compile application.js later
So eventually it would look like this
// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// compiled file.
// Read Sprockets README (https://github.com/rails/sprockets#sprockets-directives) for details
// about supported directives.
//= require jquery
//= require base
//= require whatever from plugns...
