tl;dr: Is it possible to enforce an order on callback functions that are attached to the
same hook?
Detailed question:
I've written a custom extension that modifies Category pages. It creates a subclass of
CategoryPage and inserts it using the hook "ArticleFromTitle." It works great on
its own, but unfortunately, another popular extension we use, CategoryTree, does exactly
the same thing, and it overrides my extension's modifications.
I can write my extension to check for the presence of CategoryTree and compensate for it.
Unfortunately, MediaWiki 1.28.0 always runs CategoryTree's callback after mine, so no
matter what I do, CategoryTree wins. (Strangely, in 1.27, my extension always won.)
Is there a way to ensure that my extensions ArticleFromTitle callback runs *after*
CategoryTree's callback?
Thank you very much.
