Module:Infobox mapframe
Lua error: Internal error: The interpreter exited with status 127.
Usage
Module that automatically makes a mapframe suitable for an infobox automatically, if a page's linked Wikidata item has coordinates ([Lua error: Internal error: The interpreter exited with status 127. Lua error: Internal error: The interpreter exited with status 127. (P625)]). Otherwise, an empty string is returned. The coordinates will be displayed as a point feature unless [Lua error: Internal error: The interpreter exited with status 127. Lua error: Internal error: The interpreter exited with status 127. (P402)] is specified on the Wikidata item.
Can be used from {{Infobox mapframe}}, or invoked directly by a template, or imported to another Lua module.
Script error: Lua error: Internal error: The interpreter exited with status 127.
