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 module can only be edited by administrators because it is transcluded onto one or more cascade-protected pages.

This module depends on the following other modules:

Module:Namespace detect/data (sandbox)

Usage

{{#invoke:Category handler|function_name}}

-- This module contains shared functions used by [[Module:Category handler]]
-- and its submodules.

local p = {}

function p.matchesBlacklist(page, blacklist)
	for i, pattern in ipairs(blacklist) do
		local match = mw.ustring.match(page, pattern)
		if match then
			return true
		end
	end
	return false
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 {}
end
