You can also browse our extension code in our local Subversion repository or our GitHub mirror.

1. Called from $wgExtensionFunctions array when initialising extensions

function wfSetupLivelets() { global $wgLivelets,$wgScriptPath,$wgLiveletsPath; $wgLivelets = new Livelets(); if ($wgLiveletsPath == ) $wgLiveletsPath = "$wgScriptPath/extensions/livelets"; }

1. Needed in MediaWiki >1.8.0 for magic word hooks to work properly

function wfLiveletsLanguageGetMagic(&$magicWords,$langCode = 0) { global $wgLiveletsMagic; $magicWords[$wgLiveletsMagic] = array(0,$wgLiveletsMagic); return true; } ?>
