I have Syntax Highlighting working and Scribunto working, but this extension throws the following errors in the browser console (not sure why). Using MediaWiki 1.30.0. If I comment CodeEditor from LocalSettings.php the errors go away:
VM116:125 This page is using the deprecated ResourceLoader module "jquery.ui.widget". VM116:165 This page is using the deprecated ResourceLoader module "jquery.ui.position". This page is using the deprecated ResourceLoader module "jquery.ui.core". Please use "mediawiki.ui.button" or "oojs-ui" instead. jQuery.Deferred exception: $button.data(...) is not a function TypeError: $button.data(...) is not a function at Object.updateButtonIcon (<anonymous>:506:280) at Object.updateCodeEditorToolbarButton (<anonymous>:506:345) at Object.setupCodeEditorToolbar (<anonymous>:505:837) at Object.$.wikiEditor.extensions.codeEditor (<anonymous>:516:172) at jQuery.fn.init.$.fn.wikiEditor (<anonymous>:36:196) at HTMLDocument.<anonymous> (<anonymous>:516:2260) at mightThrow (URL/load.php?debug=false&lang=en&modules=jquery%2Cmediawiki&only=scripts&skin=vector&version=0ocu5xa:49:598) at process (URL/load.php?debug=false&lang=en&modules=jquery%2Cmediawiki&only=scripts&skin=vector&version=0ocu5xa:50:269) undefined
Do I need to update some JS somewhere? Thanks.
