Haml and Sass plugin for Jekyll 0.6.2

haml_converter.rb

module Jekyll
  require 'haml'
  class HamlConverter < Converter
    safe true
    priority :low

    def matches(ext)
      ext =~ /haml/i
    end

    def output_ext(ext)
      ".html"
    end

    def convert(content)
      begin
        engine = Haml::Engine.new(content)
        engine.render
      rescue StandardError => e
          puts "!!! HAML Error: " + e.message
      end
    end
  end

  require 'sass'
  class SassConverter < Converter
    safe true
    priority :low

     def matches(ext)
      ext =~ /sass/i
    end

    def output_ext(ext)
      ".css"
    end

    def convert(content)
      begin
        engine = Sass::Engine.new(content)
        engine.render
      rescue StandardError => e
        puts "!!! SASS Error: " + e.message
      end
    end
  end
end

Today I was bit by a Jekyll / HAML problem using a similar converter, so just a comment..

HAML raises SyntaxError on parse problems. In Ruby 1.9, SyntaxError is not a child of StandardError, so rescue will miss it and probably lead to a frustrating debugging session; or, you could rescue Exception, but that seems blunt. Of course, HAML might raise other errors you're catching with StandardError.

Also, rescue expects StandardError by default, so rescue => e would be sufficient.
