Purpose[edit | edit source]

Syntax highlight text snippets, whole pages or whole files. The extension also provides a new 'hook' for other extensions to leverage as well as providing syntax highlighting for text blocks, whole pages or whole files. Line numbers can optionally be included or omitted.

Usage[edit | edit source]

  • LINES parameter
    • 0 -> no line numbers
    • 1 -> include line numbers
  • LANG parameter: language
  • SOURCE parameter
    • source=page where page is a valid page
    • source=file where file is a valid file of the Mediawiki installation accessible through the root of the installation.

Example 1[edit | edit source]

<geshi lang=LANG lines=LINES source=SOURCE> code OR page title OR filename </geshi>

Example 2[edit | edit source]

<php lines=LINES source=SOURCE> php code OR page title OR filename </php>

This usage is especially useful to integrate with other extensions (such as Form Processor).

  1. The most recent release is always available through the extension's PEAR and SVN repositories. This page is not necessarily up-to-date.
  2. 2.0 2.1 2.2 Extension:ExtensionManager does not require any modification to LocalSettings.php because ExtensionManager includes the extension.
    Note that if PHP code caching is in place (e.g. APC, eAccelerator), then to successfully complete the installation a cache flush might be needed.
  3. Modifications to LocalSettings.php is only necessary if not using Extension:ExtensionManager
