Template:Ns has subpages
yes
Detects whether the current or the given namespace has subpages enabled. Returns "yes" if it does, and an empty string otherwise.
This template can be substituted.
Usage
{{ns has subpages}}→ yes{{ns has subpages|Template}}→ yes{{ns has subpages|Category}}→{{ns has subpages|}}(main space) →{{ns has subpages|{{ns:0}}}}(main space) →{{ns has subpages|:}}(main space) →{{ns has subpages|{{ns:Talk}}}}→ yes
The template recognises namespaces which 'should' have subpages, but currently do not (see mediazilla:18437); that is, pages in Category talk:, Help: and Help talk: namespaces. Full page names can be passed, with the obvious caveat that passing the article [[Template]] or [[Category]] is... inadvisable...
{{ns has subpages|Category talk}}→ yes{{ns has subpages|File:Foo}}→{{ns has subpages|Foo}}→{{ns has subpages|:Template}}→ yes
