Module:Category handler/blacklist

This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing.

This Lua module is used in system messages, and on approximately 4,580,000 pages, or roughly 11839% 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.

Usage

{{#invoke:Category handler|function_name}}

-- This module contains the blacklist used by [[Module:Category handler]].
-- Pages that match Lua patterns in this list will not be categorised unless
-- categorisation is explicitly requested.

return {
    '^Main Page$', -- don't categorise the main page.
 
    -- Don't categorise the following pages or their subpages.
    -- "%f[/\0]" matches if the next character is "/" or the end of the string.
    '^Wikipedia:Cascade%-protected items%f[/\0]',
    '^User:UBX%f[/\0]', -- The userbox "template" space.
    '^User talk:UBX%f[/\0]',
 
    -- Don't categorise subpages of these pages, but allow
    -- categorisation of the base page.
    '^Wikipedia:Template messages/.*$',
 
    '/[aA]rchive' -- Don't categorise archives.
