But it seems there is no such thing for MediaWiki. And I think there’s a lot of itching to scratch here. A lot of MediaWiki folks haven’t experienced drush or wp-cli yet, so the itch has not been exposed yet. But I’m quickly progressing with a proof of concept: mewsh, a MediaWiki Shell.
While doing it I’m learning some more about composer (the PHP tool, not the social media service that keeps on getting better and better) and I think mewsh will become part of my wiki toolset in the next couple of weeks.
UPDATE: I gave mewsh a home at mewsh.org
