Use cases

MediaWiki installations use the SpecialVersionExtensionTypes hook to achieve more fine grained control over the list of extension types displayed on the Special:Version page. With this hook they can

• change the labels used to identify each extension type
• change the way extensions are split into groups by type

Background

The Special:Version page lists the current version of MediaWiki and all extensions installed. The listing categories the extensions based on the type provided to $wgExtensionCredits .

By default, extensions are grouped into five categories: specialpage, parserhook, variable, media, and other. This hook can be used to add or remove types and/or change the label associated with each type.

Usage

Functions attached to this hook add and remove extension types to $aExtensionTypes. The array is keyed by typeid and its values are the display labels associated with each type. typeid is a locale-independent type id used as the value for the 'type' element of $wgExtensionCredits .

Functions attached to this hook should return true so that other functions attached to this hook may run.
