Module:Caller title/doc

This module simply returns the title of the page embedding the template that directly calls this module (i.e. the page that embeds the wrapper template). It’s primarily intended for templates translated using the Translate extension, but it can be used in traditional layout templates as well (in that case, the module should be called directly in order to get the title of the translation subpage). It has two entry points, both can be called with {{#invoke:Caller title|name}}:

title

Get the full title of the template.

lang

Get the language code (subpage name). In fact, it doesn’t check if the subpage name is a valid language code, so if called from X/y/z, it’ll happily return z. The template using this functionality should ensure it’s only used on language subpages (or be okay with garbage output).
