Status

Complete enough to use for nearly every project. See the roadmap to 2.0.

Getting Started

npm install -g coffee-script-redux
coffee --help
coffee --js <input.coffee >output.js

Before transitioning from Jeremy’s compiler, see the intentional deviations from jashkenas/coffee-script wiki page.

Development

git clone git://github.com/michaelficarra/CoffeeScriptRedux.git && cd CoffeeScriptRedux && npm install
make clean && git checkout -- lib && make -j build && make test
