red_cloth.rb

require 'redcloth/textile_doc'
module RedCloth
  class TextileDoc
    def initialize( string, restrictions = [:no_span_caps] )
      restrictions.each { |r| method("#{r}=").call( true ) }
      super( string )
    end
  end
end

require 'action_view/helpers/text_helper'
module ActionView
  module Helpers
    module TextHelper
      def textilize(text, *options)
        options = [:hard_breaks, :no_span_caps] if options.nil? or options.size == 0

        if text.blank?
          ""
        else
          textilized = RedCloth.new(text, options)
          textilized.to_html
        end
      end
    end
  end
end

Thanks!
