The RandomInCategory tool is a replacement for Special:RandomInCategory that actually chooses a page randomly. Includes options for filtering results by namespace and type. To use on a wiki, replace [[Special:RandomInCategory/CATEGORY_NAME]] with [[toolforge:RandomInCategory/CATEGORY_NAME]] or [[toolforge:RandomInCategory/CATEGORY_NAME&OPTIONAL_PARAMETERS]].
Multiple categories can be specified by adding the category2=, category3=, etc. parameters to the url, e.g. [[toolforge:RandomInCategory/Fish&category2=Whales&category3=Crabs&category4=Plankton]].
By default, the script assumes the category is from en.wikipedia.org. This can be overridden by adding the server= parameters to the url, e.g. &server=commons.wikimedia.org. Do not include "https://" in the site name. The server must at one of the following Wikimedia-owned domains:
Results can be filtered by namespace and type by adding the namespace= and type= parameters to the url, e.g. &namespace=2|118&type=page. These parameters are documented as cmnamespace and cmtype at https://www.mediawiki.org/wiki/API:Categorymembers, but the "|" between namespaces can optionally be replaced with a ";" or "!" for compatibility with wikilinks.
For performance reasons, the list of items is cached for 10 minutes. To manually refresh the cache, set the purge= parameter to any value.
Set the returntype= parameter to article or subject to return the associated subject page if the randomly chosen page is a talk page. Similarly, returntype=talk will return the associated talk page if the randomly chosen page is a subject page. If the associated page does not exist, the original randomly chosen page will be returned.
The script will return the URL of the article and other debugging data instead of actually performing the redirect if the debug= parameter is set to any value.
Any other parameters in the URL will be passed on to the target page.
