A simple one-liner to convert all JavaScript to CoffeeScript

A simple one-liner to convert all JavaScript in a folder to CoffeeScript

First, make sure you have installed “js2coffee” ( and js2coffee.org is real cool for single files too ):

npm install js2coffee

And then just paste this:

for f in *.js; do js2coffee -it $f > ${f%%.*}.coffee; rm $f; done;

`-it` options modifies the spaces to tabs, remove it if you prefer spaces.

Enjoy!
