Sh2
===

Client-side syntax highligher plugin for Rails.
Based on [SyntaxHighlighter2](http://alexgorbatchev.com/wiki/SyntaxHighlighter) by Alex Gorbatchev.


Example
=======

In your layout:

<head>
  <%= include_syntax_highlighter_assets(:theme => :midnight, :brushes => :all) %>
  <%= include_syntax_highlighter_assets(:theme => :midnight, :brushes => [:ruby, :shell, :jscript, :sql, :xml, :css]) %>
</head>

Brushes stands for lang plugins. See PLUGIN_ROOT/assets/javascripts/shBrush* for supported languages.
Themes located in PLUGIN_ROOT/assets/stylesheets/shTheme*

At the bottom of page (or after all to-be-highlighted-code-blocks) call sh2_highlight_code helper

<%= sh2_highlight_code %> 


Code like this will be highlighted:

<pre class="brush: js;"> 
function onThemeChange(sender)
{
  var parts = sender.value.split('|');
  document.getElementById("theme").href = "Styles/" + parts[1];
  document.body.style.backgroundColor = parts[0];
}
</pre>
