Module:Category handler/data/doc

This module is used in conjunction with the category handler module to manage categories; it is a very important template used on millions of pages.

This Lua module is used in system messages, and on approximately 4,630,000 pages, or roughly 8% of all pages. Changes to it can cause immediate changes to the Wikipedia user interface. To avoid major disruption and server load, any changes should be tested in the module's /sandbox or /testcases subpages, or in your own module sandbox. The tested changes can be added to this page in a single edit. Please discuss changes on the talk page before implementing them.

This module depends on the following other modules: Module:Category handler/config Module:Category handler/shared Module:Category handler/blacklist
