Example of Assetfile used with rake pipeline

assetfile

Use gem to get rake-pipeline and rake-pipeline-web-filters (both on github w/ docs on installation/setup)

create an Assetfile in your project's root  that looks something like the one shown below:

The handlebars compilation section is in the middle though you may check out the others for edification or whatnot.

    require 'rake-pipeline-web-filters'
    input "static" do
      output "static/"
      #compile the JS files that the coffeescript compiler outputs and wrap using minispade
      match "compiledJS/**/*.js" do
        minispade :rewrite_requires => true, :string => false, :module_id_generator => proc { |input| 
          id = input.path.dup
          id.sub!('compiledJS/', '') 
          id
        }
        concat "js/src/applicationcompiled.js"
      end

      #compile handlebars templates into Ember.TEMPLATES
      match "coffee/**/*.handlebars" do
        handlebars
        concat "js/src/applicationtemplates.js"
      end

      #SASS compile from single main.sass file which imports all partials
      match "sass/main.sass" do
        sass
        concat "css/application.css"
      end
    end
