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

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As far is I understand it, using DefaultSettings.php is outdated, we should be using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
