This gem provides a Jekyll converter for Less CSS files.
Install the gem:
[sudo] gem install jekyll-less
In a plugin file within your Jekyll project's _plugins directory:
# _plugins/my-plugin.rb
require "jekyll-less"
Alternatively, add a configuration option in _config.yml:
gems: ['jekyll-less']
Place .less files anywhere in your Jekyll project's directory. These will be converted to .css files with the same directory path and filename. For example, if you create a Less file at css/my-stuff/styles.less, then the corresponding css file would end up at css/my-stuff/styles.css.
Already using bundler to manage gems for your Jekyll project? Then just add
gem "jekyll-less"
to your gemfile and create the following plugin in your projects _plugins directory. I've called mine bundler.rb. This will automatically require all of the gems specified in your Gemfile.
# _plugins/bundler.rb
require "rubygems"
require "bundler/setup"
Bundler.require(:default)
