Feel free to reopen the ticket if it will not work on local wiki

How exactly can we check it on local wiki, @Pastakhov?

I meant that it depends on the value of the $wgLanguageCode variable.
On test.wikipedia.org it is en thus there are no Localized magic words.
For check localized magic words you should set $wgLanguageCode to corresponded value.

Not funny.

I found other way - add uselang parameter to url, but it is more a bag that a feature (and should be fixed)
For example https://test.wikipedia.org/w/index.php?title=Pride_and_Prejudice&action=edit&oldid=323245&uselang=de
Or change it by language toolbar at the top of page. But in this case I see only part of language aliases.
Have no idea why.

beaware that uselang usually (unless there is very special hook in test wiki) only changes the UI language, not the content language of the site.

@IKhitron, It does not work since there are only part of language aliases (localized magic words).
And as I wrote, I have no idea why there are only part of them.
In any case this behavior is a bug, CodeMirror should use only language from $wgLanguageCode and it will be fixed soon.
For check localized magic words you should set $wgLanguageCode to corresponded value or use the CodeMirror extension on wiki with $wgLanguageCode have corresponded value (it's no joke).

@eranroz, yes, uselang should change the UI language only, but one affects also to list of Magic Words used in CodeMirror. Not sure where the bug is, in MW Core or CodeMirror, hope the bug in CodeMirror and will be easily fixed.

P.S. created another task T170130

You mean you actually expect I'll change the configuration of test.wikipedia.org?

@kaldari Is there a test wiki in any other language? It would help us to test that the magic words work properly on languages outside of English.

We have the beta cluster which also has CodeMirror since I deployed it there. Here's the German version: https://de.wikipedia.beta.wmflabs.org/wiki/Wikipedia:Hauptseite I believe it needs a new account and doesn't work with CentralAuth. I could be wrong.

@IKhitron: I tried it out at https://de.wikipedia.beta.wmflabs.org/ and it seems to work correctly. "{{SORTIERUNG:AAA}}", the German localization for {{DEFAULTSORT}}, is correctly recognized as a magic word and highlighted as red instead of purple.

@kaldari, we have a problem. It does not work. See here. Thank you.

Thank you.

I checked to see if this was a problem on Dutch Beta -- it works correctly there, as in the screenshot below. This is probably an RTL issue.

I was casually looking into this thing again...

First of all, there definitely is something wrong with this part of the code. If you take: {{DEFAULTSORT:AAAA}}
The regex stream.match(/^([^\s\u00a0}[\]<{'|&:]+)(:|[\s\u00a0]*)(\}\}?)?(.)?/); that it uses, matches and returns DEFAULTSORT:A (dropping three A's and the 3rd capture group is always undefined).. It probably should be more something the likes of ^([^}[\]<{'|&:]+)(:([^[\]<'|&:]*))?\}\}

But the reason the Hebrew version is not matching, and this took me a while to spot, is because it contains a space character. Magic words by convention do not have spaces, so this regex isn't expecting those and doesn't match on it.

I'm kinda surprised we have magic words with spaces, we should check how many other languages have magicwords with spaces and if that is ok or not.. (it probably is)
