Intranet/Intranet Extensions

This article details a list of extensions. There are many extensions already installed but not activated when installing Mediawiki via Intranet/Intranet Installation and you should explore those at /var/www/html/mediawiki/extensions/. Other extensions are installed at /var/www/html/local-extensions/ in this documented scheme, which keeps them out of the way to avoid accidentally overwriting them.

Extensions can be tricky to manage and here we present a scheme that should cover all ways of loading them

LocalSettings.php

The scheme used here is as follows:

• Provided extensions - these come with the installation and do not need downloading separately. Some of them need additional software, for example VisualEditor (already covered in Intranet/Intranet Installation) or Scribunto and Graph #### TODO indicate these.
• Local maintained extensions - these are downloaded (usually with git) to /var/www/html/local-extensions/
• Some extensions are disabled when using command line tools
• Some extensions do not support the modern calling mechanism - wfLoadExtension - and have to be called via require_once

# Provided extensions
wfLoadExtension( 'ParserFunctions' );
wfLoadExtension( 'DynamicSidebar' );
wfLoadExtension( 'PdfHandler' );
wfLoadExtension( 'Nuke' );

# CirrusSearch does not have an extension.json
require_once( "$IP/extensions/CirrusSearch/CirrusSearch.php" );

##### Locally maintained extensions
##### $wgExtensionDirectory gets repeatedly redefined as needed and then reset back to the default

# These extensions have a nasty habit of breaking maint scripts, so are not loaded for command line mode
if ( !$wgCommandLineMode ) 
{
    $wgExtensionDirectory = '/var/www/html/local-extensions';
    wfLoadExtension( 'Auth_remoteuser' );
    wfLoadExtension( 'ExternalData' );
    $wgExtensionDirectory = '$IP/extensions';
}

# local extensions that are always loaded
$wgExtensionDirectory = '/var/www/html/local-extensions';
wfLoadExtension( 'WikiCategoryTagCloud' );
wfLoadExtension( 'GraphViz' );
wfLoadExtension( 'MyVariables' );
$wgExtensionDirectory = '$IP/extensions';

# local extensions that don't support wfLoadExtension
require_once ( "$IP/../local-extensions/AdminLinks/AdminLinks.php" );
require_once   "$IP/../local-extensions/SimpleTooltip/SimpleTooltip.php";

##### /Locally maintained extensions

Many of these extensions need configuration. Comment out all of the above and then enable them one by one as required.
