Overriding MW core messages via extension - Wikitech-l

6 Sep 2018

Is it possible to override messages part of MediaWiki core via an
extension. I tried adding to an extension's en.json file and that didn't
seem to work, but am wondering if there's another way.

Is it possible for an extension to add a language? If so, then the
extension's mylang.json file could only define those that need overriding
and fallback on another language for everything else.

Thanks,
James
