CodeRay filter for Haml. Specify which language to highlight with a shebang followed by the language name:
:coderay
  #!ruby
  if true
    puts "hello"
  end
Use :coderay_raw if you want to disable #{} interpolation.
The default encoder and encoder options are :div and {}, respectively,
and they can be altered through:
Haml::Filters::CodeRay.encoder
Haml::Filters::CodeRay.encoder_options
For example, if you want to provide your own styling instead of the default inline styling:
Haml::Filters::CodeRay.encoder         = :div
Haml::Filters::CodeRay.encoder_options = { :css => :class }
gem install haml-coderay
