Rails plugin Markdown

1. RDiscount

http://github.com/rtomayko/rdiscount

> sudo gem install rdiscount

Usage

RDiscount implements the basic protocol popularized by RedCloth and adopted by BlueCloth:

require 'rdiscount'
markdown = RDiscount.new("Hello World!")
puts markdown.to_html

Additional processing options can be turned on when creating the RDiscount object:

markdown = RDiscount.new("Hello World!", :smart, :filter_html)

Inject RDiscount into your BlueCloth-using code by replacing your bluecloth require statements with the following:

begin
  require 'rdiscount'
  BlueCloth = RDiscount
rescue LoadError
  require 'bluecloth'
end

2. BlueCloth

http://deveiate.org/projects/BlueCloth

> sudo gem install bluecloth

Usage

require "bluecloth"

markdown = BlueCloth.new("<p>Hi</p>") or Markdown.new("<p>Hi</p>")

markdown.to_html

Tip : # BlueCloth has set the top-level 'Markdown' constant

::Markdown = ::BlueCloth unless defined?( ::Markdown )
