--[[This code does not work ib all namespaces where the Translate tool works. -- It works in the main namespace on Meta because it allows subpages there -- It would not work in the main namespace of English Wikipedia (but the -- articles are monolignual on that wiki). -- On Meta-Wiki the main space uses subpages and its pages are translated. -- The Translate tool allows translatng pages in all namespaces, even if -- the namespace officially does not have subpages. -- On Meta-Wiki the Category namespace still does not have subpages enabled, -- even if they would be very useful for categorizing templates, that DO have -- subpages (for documentatio and tstboxes pages). This is a misconfiguration -- bug of Meta-Wiki. The work-around is to split the full title and then -- get the last titlepart. local subpage = mw.title.getCurrentTitle().subpageText --]] local titleparts = mw.text.split(mw.title.getCurrentTitle().fullText, '/') local subpage = titleparts[#titleparts] return this.checkLanguage(subpage, '')end -- [[Get the last subpage of the current frame if it is a translation.
