Module:Category handler/shared

File:Green check.svg

This module is rated as ready for general use. It has reached a mature state, is considered relatively stable and bug-free, and may be used wherever appropriate. It can be mentioned on help pages and other Wikipedia resources as an option for new users. To minimise server load and avoid disruptive output, improvements should be developed through sandbox testing rather than repeated trial-and-error editing.

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

Warning

This Lua module is used in system messages, and on approximately 4,970,000 pages, or roughly 60632% of all pages.
Changes to it can cause immediate changes to the Calamity Wiki 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.

	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.

		mappingsKey = 'talk'
	else
		mappingsKey = mw.site.namespaces[titleObj.namespace].name
	end
