LESS folder watcher with optional debug information

A nodejs script that allows you to watch a folder for changes and compile the less css files into another folder, optionally passing original lessc compiler arguments. When the --line-numbers=mediaquery argument is used, this nodejs script will fix the syntax so that webkit understands it too.

I only added those latter modifications. All credits should go to those who did the most work (which is like 99%):

Jonathan Cheung for writing the entire less watcher https://github.com/jonycheung/Dead-Simple-LESS-Watch-Compiler

Mikeal Rogers for writing the original folder watch script https://github.com/mikeal/watch

Installation instructions

First, install LESS. Best to make them accessible from anywhere in your shell.

npm install less --global

Then, install lesswatch.

npm install lesswatch --global

Usage

lesswatch [options] <source-folder> <destination-folder>

Example

lesswatch --line-numbers=mediaquery less css

That will watch ./less folder and compile the less css files into ./css when they are added/changed and add mediaquery-formatted debug info to the css for debugging with webkit-inspector.

• This script only compiles files with .less extension. More file extensions can be added by modifying the allowedExtensions array.
• Files that start with underscores _style.css or period .style.css are ignored. This behavior can be changed in the filterFiles() function.
