# install it

make install

Installer less

npm install -g less

Command-line usage

Once installed, you can invoke the compiler from the command-line, as such:

$ lessc styles.less

This will output the compiled CSS to stdout, you may then redirect it to a file of your choice:

$ lessc styles.less > styles.css

Pour minifier le code, il faut installer YUI Compressor

$ aptitude install yui-compressor

To output minified CSS, simply pass the -x option. If you would like more involved minification, the YUI CSS Compressor is also available with the –yui-compress option.

To see all the command line options run lessc without parameters.

Un petit script pour automatiser tout ça

#!/bin/bash
cd `dirname $0`
lessc --yui-compress public/less/bootstrap.less > public/css/bootstrap.min.css
