Topic on Extension talk:Babel/Flow

Languages without ISO code can only be added locally in a wiki using templates.

Can we add languages that have no ISO-363 code, like toki-pona?

You can create a template matching MediaWiki:babel-template in your wiki and use it. --Base (talk) 13:06, 11 November 2017 (UTC)

You can, if you create such templates yourself, like Base explains above. Without a ISO code it won't be added to the Babel extension.

Toki Pona has an ISO code now (search "iso 639-3 tok", i can't send links), so it should be added to MediaWiki.

This discussion is about Babel, not MediaWiki in general.
