Модуль:Suppress categories

Документацію для цього модуля можна створити у Модуль:Suppress categories/документація

-- 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 )

    if mw.ustring.match( beforePipe, '[%[%]<>{}%c\n]' ) then
        return all
    else
        return ''
    end
end

-- Preprocess the content if we aren't being called from #invoke,
-- and pass it to gsub to remove valid category links.
local function suppress( content, isPreprocessed )
    if not isPreprocessed then
        content = mw.getCurrentFrame():preprocess( content )

        processCategory
    )

end

-- Get the content to suppress categories from, and find
-- whether the content has already been preprocessed. (If the
-- module is called from #invoke, it has been preprocessed already.)
