Usage
From wikitext
From wikitext this module must be used via the {{ns has subpages}} template. Please see the template page for documentation.
From Lua
Usually Lua modules should use mw.site.namespaces[namespace].hasSubpages rather than this module. But if you have a good reason, it can be accessed like this:
Load the module: <syntaxhighlight lang="lua"> local mNsHasSubpages = require('Module:Ns has subpages') </syntaxhighlight>
The subpage information can be found with the ._main function: <syntaxhighlight lang="lua"> mNsHasSubpages._main(ns, frame) </syntaxhighlight>
- ns is the namespace name, number, or a page name. It defaults to the current namespace.
- frame is a frame object with which we can call frame:callParserFunction if necessary. This is optional, and intended for internal use.
