Protected "Module:Suppress categories": High-risk Lua module; 1,000+ transclusions ([Edit=Require autoconfirmed or confirmed access] (indefinite))
-- This is a simple module to strip categories from wikitext. It does
-- not support nested links or magic words like __TOC__, etc. Even so,
-- it should still handle most categories.
local p = {}
-- Detects if a category link is valid or not. If it is valid,
-- the function returns the blank string. If not, the input
-- is returned with no changes.
local function processCategory( all, submatch )
local beforePipe = mw.ustring.match( submatch, '^(.-)[%s_]*|[%s_]*.-$' )
beforePipe = beforePipe or submatch
if mw.ustring.match( beforePipe, '[%[%]<>{}%c\n]' ) then
return all
else
return ''
end

-- and pass it to gsub to remove valid category links.
