پودمان:Mapshapes

توضیحات پودمان[ایجاد]

-- This fetches referenced wikidata entries (P527 - has part, or
-- P2670 - has parts of the class ) and adds mapshapes, with colors acc. to
-- P465 (sRGB color hex triplet) or P462 (color)

-- TODO: Ideally, this could be merged into Module:map (incl. the Template:Mapshapes)

-- test code:
-- frame={["args"]={["default-color"] = "#ff0000"}, ["expandTemplate"] =function(a,b) mw.logObject(b); end}
-- p.showOne(frame, "Q2400801", {})
