Jekyll extension to easly use HAML instead of plain HTML

HAML Jekyll extension

Auto-generates html and css files for your layouts in HAML/SASS (you can still have your liquid syntax)

This extension uses jekyll_ext, which allows you to extend the Jekyll static blog generator without forking and modifying it’s codebase.
With this code, not only do your extensions live in your blog directory, but they can also be shared and reutilized.

Use this extension with jekyll_ext by just cloning this repo into the extensions dir of your blog: git clone git://github.com/codegram/haml_jekyllextension.git _extensions

More information about jekyll_ext can be found here: Jekyll Extensions -= Pain
