The InterwikiRegex extension adds regex capability for interwiki links. Or something like regex; actually, it's str_replace.

Installation

• Create a folder in the extensions folder named InterwikiRegex
• Move the files to the extensions/InterwikiRegex/ folder
• Edit LocalSettings.php in the root of your MediaWiki installation, and add the following line near the bottom:

require_once("$IP/extensions/InterwikiRegex/InterwikiRegex.php");

Usage

Configuration settings

// Array of interwiki prefixes and the string replacements
$wgInterwikiRegexString = array (
        'urbandictionary' => array (
                ' ' => '+',
                '_' => '+',
        )
);

This will cause [[urbandictionary:would of]] to link to http://www.urbandictionary.com/define.php?term=would+of , once you have added the appropriate interwiki link using Special:Interwiki.
