h2(#toc_cr){clear:none}. CodeRay

To include "CodeRay":http://coderay.rubychan.de/ syntax highlighting support in a page you need to have the @coderay@ gem installed, and you need to include the CodeRay stylesheet in your layout. The following example shows a page that uses CodeRay syntax highlighting combined with Textile markup.

Note how the @coderay@ block is enclosed by a @notextile@ block. This ensures that the Textile filter does not clobber the generated syntax highlighting.

<pre class="code">

title:  CodeRay Example
filter:
  - erb
  - coderay
  - textile
--- 
h2. <%= h(@page.title) %>

This is the @render_page@ function from the Webby static website generation
system. It is used to render a page by applying the specified filters in
succession to the page contents.

<notextile>&lt;notextile&gt;
&lt;coderay lang="ruby" line_numbers="inline"&gt;
# call-seq:
#    render_page    => string
#
# Apply the desired filters to the page. The filters to apply are
# determined from the page's meta-data.
#
def render_page
  ary = []
  str = ::Webby::File.read(@page.path)

  @page.filter.to_a.each do |filter|
    str = self.send(filter + '_filter', str)
  end

  str
end
&lt;/coderay&gt;
&lt;/notextile&gt;</notextile>
</pre>

There are more options that can be passed to the CodeRay syntax highlighter than those shown in the example above. Take a look at the RDoc documentation for the "CodeRayFilter":http://webby.rubyforge.org/rdoc/classes/Webby/CodeRayFilter.html class for more information.
