See it in action:


Just surround your code like this (note that your code must be HTML escaped):

<pre class="brush:[code-alias]"> ...Your Code Here... </pre>

or like this:

<script type="syntaxhighlighter" class="brush: js"><![CDATA[ ...Your Code Here... ]]></script>

Replace the [code-alias] segment with the type of code you have. For a list of all available brush aliases, see here. There's some pros and cons for each of the above options here.

Admins can provide additional aliases (like <plsql> your code </plsql>) by adding to the extension file code like this:

// This is a comment. Comments are not displayed in the browser //
$wgHooks['ParserFirstCallInit'][] = 'syntaxHighlightingExtension';
function syntaxHighlightingExtension( &$parser ) {
    $parser->setHook( 'PLSQL', 'syntaxHighlightingRenderHtml' );
    return true;

function syntaxHighlightingRenderHtml($input, $args, $parser, $frame){
    return "<pre class=\"brush:sql\">\n" . $input . "</pre>";


  • Download the latest version of SyntaxHighlighter and extract the files in a directory called Syntax in your extensions/ folder.
  • Add the code from the files under #Code section on this page to this directory.
  • Add the following to LocalSettings.php:

Alternative installation[edit]

Alternatively, you could handle the installation of the appropriate files and the generation of this content all with a script. An example of this can be seen here.
