Extension:SubPageList

The SubPageList extension is a lightweight extension to display subpages.

Feature overview

 * Adds a  or   parser hook that you can use to list subpages.
 * Backward compatible with the SubPageList3 extension.
 * Supports multiple parameters that enable you to customize the subpage list.
 * Full integration with the Validator extension.

Download
SubPageList requires Validator 0.4.2 or above in order to work. A compatible copy of Validator always comes bundled with the regular releases, and is automatically loaded by SubPageList, so you do not need to worry about it when using one of these. If you are getting the code from SVN, make sure you also get a copy of Validator (see here for instructions).

Installation
Once you have downloaded the code, place the SubPageList and Validator directories within your MediaWiki 'extensions' directory. Then add the following code to your LocalSettings.php file:

MediaWiki has a setting that specifies which namespaces can have subpages. For namespaces where this is not set, creating  will not result in   being a child page of. See Manual:$wgNamespacesWithSubpages. Typically you want to also enable this for the main namespace, as follows:

Configuration
Configuration of SubPageList is done by adding simple PHP statements to your LocalSettings.php file. These statements need to be placed AFTER the inclusion of SubPageList. The options are listed below and their default is set in the SubPageList settings file. You should NOT modify the settings file, but can have a look at it to get an idea of how to use the settings, in case the below descriptions do not suffice.

Automatic refresh
As of version 0.3, you can choose to automatically refresh subpage lists that are on the base page of subpages you add, move or delete, or on one of the subpages of the base page. This behaviour is off by default as it can produce extra load on your server, but can be turned on with this code:

General subpage settings
MediaWiki itself has some support for subpages, which causes back links to be displayed on subpages to their parent pages. To enable this you need to set wgNamespacesWithSubpages, which is a per namespace setting, like shown below:

Usage
You have the choice to either use a tag extension (  or   ) or use a parser function (   or   ). All these take the same parameters and behave identically.

Syntax
Tag extension with only the required parameters.

Tag extension with all parameters.

 Tag extension with all parameters using the default parameter notation.

{page, Text} Parser function with only the required parameters.

Parser function with all parameters.

Parser function with all parameters using the default parameter notation.

Examples
Listing the subpages of the current page with default options:

Listing the subpages of page "Foobar" with the "ol" format:



Using several options and making use of the default parameter system of the parser function (again for page "Foobar"):

Internationalization
SubPageList is fully internationalized. Translation of SubPageList messages is done through translatewiki.net. The translation for this extension can be found here. To add language values or change existing ones, you should create an account on translatewiki.net, then request permission from the administrators to translate a certain language or languages on this page (this is a very simple process). Once you have permission for a given language, you can log in and add or edit whatever messages you want to in that language.
