CoffeeScript adapter for the Rails asset pipeline. Also adds support to use CoffeeScript to respond to JavaScript requests (use .coffee
views).
Since Rails 3.1 Coffee-Rails is included in the default Gemfile when you create a new application. If you are upgrading to Rails 3.1 you must add the coffee-rails to your Gemfile:
gem 'coffee-rails'
$ bundle install
$ bundle exec rake test
If you need to test against local gems, use Bundler's gem :path
option in the Gemfile.
