CoffeeScript
This folder contains the CoffeeScript file that will be compiled to the static
directory. By default, we're compile and merge all the files ending .coffee
into static/js/application.js.
Install the Compiler
CoffeeScript compiler are written in JavaScript. You'll need to install Node and npm (Node Package Manager) to be able to install the CoffeeScript compiler.
Mac OS X
Install Node via Homebrew, then use npm:
$ brew install node
$ curl http://npmjs.org/install.sh | sh
$ npm install -g git://github.com/jashkenas/coffee-script.git
(Note that we're using the edge version of CoffeeScript for now, as there was some issue with directory watching in 1.3.1.)
Try to run coffee and make sure you get a coffee prompt.
Debian/Ubuntu
Conveniently, you can install Node via apt-get, then use npm:
$ sudo apt-get install nodejs npm &&
$ sudo npm install -g git://github.com/jashkenas/coffee-script.git
Compiling
CoffeeScript is compiled when you update assets using the command:
$ paver update_assets
Testing
We use Jasmine to unit-test the JavaScript files. See docs/en_us/internal/testing.rst for details.
