CoffeeScript

A language compiling into JavaScript, with a nice syntax close to Python, with some flavors of Ruby as well! See ​http://coffeescript.org/ and ​CoffeeScript for more information on background and features.

The easiest way to install a ready-to-use CoffeeScript compiler is to first install ​nodejs, then:

npm install -g coffee-script

We are using CoffeeScript version 1.x in Trac 1.3.2+ and in the meantime, nothing prevents you to use it in your plugins! Also see alternatives to ITemplateStreamFilter.
