Hi,
The importing of Lua modules across wikis is currently broken[1]. They will appear without syntax highlighting and not work in {{#invoke}}'s.
I have a patch up for review to fix it, and hope to deploy it early next week. In the meantime, I can fix individual modules using a server-side script; find me on IRC (in #wikimedia-tech as "legoktm") or leave a note on the Phabricator ticket.
