Module: Category handler/shared

40x40px

This module is rated as ready for general use. It has reached a mature form and is thought to be relatively bug-free and ready for use wherever appropriate. It is ready to mention on help pages and other Wikipedia resources as an option for new users to learn. To reduce server load and bad output, it should be improved by sandbox testing rather than repeated trial-and-error editing.

local p = {}

	for i, pattern in ipairs(blacklist) do
		local match = mw.ustring.match(page, pattern)
		if match then
			return true

end

function p.getParamMappings(useLoadData)
	local dataPage = 'Module:Namespace detect/data'
	if useLoadData then
		return mw.loadData(dataPage).mappings
	else
		return require(dataPage).mappings
	end
end

function p.getNamespaceParameters(titleObj, mappings)
	-- We don't use title.nsText for the namespace name because it adds
	-- underscores.
	local mappingsKey
	if titleObj.isTalkPage then
		mappingsKey = 'talk'
	else
		mappingsKey = mw.site.namespaces[titleObj.namespace].name
	end
	mappingsKey = mw.ustring.lower(mappingsKey)
	return mappings[mappingsKey] or {}
