Using Barista with Jammit to package and compile CoffeeScript

jammit.rake

# simply run rake jammit:package to compile your coffeescript and then package up all your assets
# including the newly compiled javascripts

namespace :jammit do
  task :package do
    Rake::Task["barista:brew"].invoke
    Jammit.package!
  end
end

I apologize for the ambiguity. This is a custom rake task that I have in lib/tasks of a Rails 3.0 project. I use it to compile my coffeescript into the public/javascripts folder where Jammit can then bundle it up as part of my assets package.
Quite handy for heroku if you don't want to have to deal with getting coffeescript to compile on heroku. Simply run this task as part of a git commit hook before you push up the heroku.

You can just run:

rake jammit:package

Thanks rweald, I'll have to remember this bit when I start experimenting with heroku.
