What would you like to do?
Haml/Sass builder script (great for Wordpress themes & other HTML-like templates)
require 'digest/md5'
=begin
About:
This script automatically runs on a 2-second loop, searches the current directory for haml & sass files that have been modified since the last iteration and builds them as needed into a file with the same name minus the .haml/sass extension. I wrote it so I could use Haml & Sass to develop Wordpress themes.
How-to:
1) Name your source files with the extension you'd like them to have, then add ".haml" or ".sass" as appropriate...
For example: index.php.haml and styles.css.sass
2) Open a terminal window in your development directory and run "ruby build.rb"
3) Tweak your haml & sass, refresh your PHP app (ie your Wordpress site) & Enjoy!
Have fun,
