Redcloth with CodeRay

Adds CodeRay syntax highlighting support to RedCloth, with a ‘source’ tag. See the examples below.

A short summary of what you can do:

• <source>foo</source> - Use this tag to produce CodeRay highlighted HTML for the contents within that tag. The language defaults to Ruby.
• <source:css>foo</source> - Highlight as usual, but highlight as CSS. Supports everything CodeRay supports. Refer to the CodeRay documentation for a list of supported languages.
• You can also use the <code> tag.

Installing

Installation as usual:

 sudo gem install redclothcoderay

You can also install the gem via github, to get the latest HEAD.

 sudo gem install augustl-redclothcoderay --source=http://gems.github.com/

Using

A short example.

 require 'rubygems'
 require 'redcloth'
 require 'coderay'
 require 'redclothcoderay'

 RedCloth.new('I am *bold* and <source>@hi_tech</source>').to_html

You can specify the CodeRay options, too (defaults to RedclothCoderay::CODERAY_OPTIONS).

  RedclothCoderay.coderay_options :line_numbers => :table

Example

This input:

 Hello, this is *textilized*. It also has <source>@inline_code_examples</source>!

 What about a multi-line code sample?

 <source:html>
 <h1>Hello, world!</h1>
 </source>

Produces this output (indented for clarity):

 <p>
     Hello, this is <strong>textilized</strong>. It also has
     <code class="inline_code">
         <span class="iv">
             @inline_code_examples
         </span>
     </code>!
 </p>

 <p>
     What about a multi-line code sample?
 </p>
 <div class="multiline_code">
     <span class="ta">&lt;h1&gt;</span>Hello, world!<span class="ta">&lt;/h1&gt;</span>
 </div>
