Module:Namespace detect/data/doc

This is a documentation subpage for Module:Namespace detect/data.
It may contain usage information, categories and other content that is not part of the original module page.

This Lua module is used in system messages, and on approximately 4,970,000 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 is a data page for Module:Namespace detect and Module:Category handler/shared. It is loaded by the main module using mw.loadData, which means it is only processed once per page rather than once per #invoke.
