Issue

Enabling Semantic Glossary in MediaWiki 1.31.5 produces the following error

Fatal error: Uncaught Error: Call to undefined method ExtensionRegistry::load() in extensions/SemanticGlossary/SemanticGlossary.php:27 

Stack trace:

Steps to reproduce the observation (recommendation is to use the sandbox):

Thanks for reporting. Note that SG does not work with MW 1.35+ even if it is loaded.

[krabina]

It seems that the followingg approach is working:

• update Semantic Glossary to master
• update Lingo to master
• envoke both in LocalSettings.php

It works in my setup now in MW 1.35. The only thing I see that is this notice and warning, but only on Special:Version:

Notice
: Undefined index: parserhook in
.../extensions/Lingo/src/Lingo.php
on line
89


Warning

@krabina And the bubble show?

[krabina]

yes:

[kghbln]

Ok, thanks. Last time on sandbox I had no bubbles. Will give it another shot.

[kghbln]

Nope, not working on sandbox. Moreover with Composer I cannot longer install master so I had to check out master with Git. Additionally I to not get the Notices on Special:Version you mentioned. I am giving up on this.

[krabina]

did you invoke both in LocalSettings.php, first Lingo, ,then SG?

Sure yes. I guess some other extension may interfere. However I have no time to figure this out a the moment. Also I am on MW 1.35.0-rc2 which I cannot upgrade at the moment. Perhaps MediaWiki is at play to though this would surprise me at the moment.

I think a first step could be a current (working) release of Lingo: https://www.mediawiki.org/wiki/Topic:W365ntpdz01m3zif. Not sure if it is really working, since Travis CI seems to be not triggered. Last Travis build is 3 years old: https://travis-ci.org/github/wikimedia/mediawiki-extensions-Lingo/builds. I forked the repo from Github to manually trigger Travis...

[gesinn-it-gea]

Lingo definitely requires some love before a next release. All Travis build jobs failed: https://travis-ci.org/github/gesinn-it/mediawiki-extensions-Lingo/builds/758499039

[gesinn-it-gea]

Btw. the above mentioned fork of Lingo was not meant to be permanent. It was just to allow manually triggering Travis...

[kghbln]

Very much indeed. Heaps of love needed. Helping hands appreciated!

[krabina]

I guess this is fixed.
Latest version 3.0.0 (5feb7e4) 18:51, 21. Jun. 2021 is working for me in 1.35
