Thank you, Gergo, this is working fine now!
regards, Bernhard

It should be $services = $config->get( 'ShariffServices' );
The actual error is an unrelated configuration problem with your wiki (or possibly a MediaWiki core bug where it tries to use a certain type of error handling too early in the request lifecycle), that's triggered during rendering the error about configuration not having a Services key.

Hi,
in my first attempt at jumping into improving a mediawiki extension, I am failing at a very basic step.
I want to make the extension configurable and followed this advice: [ https://www.mediawiki.org/wiki/Manual:Configuration_for_developers | https://www.mediawiki.org/wiki/Manual:Configuration_for_developers ]
this is my extension.json I added:
"config": { "ShariffServices": { "value": "["twitter","facebook","pinterest"]", "description": "configuration of available services" } }, "ConfigRegistry": { "Shariff": "GlobalVarConfig::newInstance" },
now in the baisc PHP file of the extension, I am trying use MediaWiki\MediaWikiServices; $config = MediaWikiServices::getInstance()->getConfigFactory()->makeConfig( 'Shariff' ); $services = $config->get ('Services');
but the last line leads to [XtqcaewKU0Q3UCukKmZO9AAAABM] /index.php?title=Main_Page Error from line 3061 of ../includes/parser/Parser.php: Call to a member function matchStartAndRemove() on null

What am I doing wrong?
As far is I understand it, using DefaultSettings.php is outdated, we should be using extension.json. But I can't get it to work.
Can anybody point me to a simple extension that uses this mechanism correctly?
so long, Bernhard
