https://www.mediawiki.org/wiki/Template:Js_doclink creates links of the above format, so it'd be good to have those working again (although I'm sure that template will be updated with the new URL structure once the new docs are all sorted out).

I think this needs to be done in the JSDoc theme... some kind of code snippet that checks the hash fragment and does a redirect on the client.

I can't submit a patch to jsdoc/wmf-theme (Permission denied), so I made a PR to GitHub, do what you want with it: https://github.com/wikimedia/jsdoc-wmf-theme/pull/4.

Hmm, that is annoying. I have created T364361: Configure jsdoc/wmf-theme repo permissions

@Jack_who_built_the_house sorry about that - I've added you to that repo so you should be able to push patches now. Thanks for working on this!

Definitely missing. I just tried "see documentation" on [[mw.OOUI/Windows/Simple messages]], and get 404. Finally get from somebody a right address, and documenfation is missing too, but that's another story, not for this task.

To add some detail to IKhitron's post:

Steps to reproduce

• Visit https://doc.wikimedia.org/oojs-ui/master/js/#!/api/OO.ui-method-alert

What happens?

• Redirects to https://doc.wikimedia.org/oojs-ui/master/js/OO.ui-method-alert.html
• 404

What should happen instead?

• Redirects to https://doc.wikimedia.org/oojs-ui/master/js/OO.ui.html#.alert

Latest patch released in v1.1.0. Let's leave this open and see if the issues identified in recent comments have been fixed

Not all methods seem to redirect properly. For example, the redirect for https://doc.wikimedia.org/oojs/master/#!/api/OO-method-inheritClass doesn't have the necessary dot in front.

Having 100% of URLs redirect properly was not the goal; there is no simple pattern for the matches and approximating it wouldn't be worth the effort. As for OO methods, I used the capital letter as a heuristic to tell classes (that generally have instances, like mw.Uri) from namespaces (that generally have members, like mw, mw.util). OO would be a special case here as a namespace starting with a capital letter. But I think OO methods have been using JSDuck for a long time? Is a redirect really needed here?

Well, Bing still has the old links. I thought that meant other search engines will also do the old links but that seems false and I agree that it's probably not worth the extra effort.
