Create MediaWiki Project[edit]

make sure your user is part of group www-data

/var/www/html$ sudo chown www-data.www-data mediawiki-1.33.2
/var/www/html$ sudo chmod g+w mediawiki-1.33.2/
/var/www/html$ sudo chown -R www-data.www-data wiki

Create Eclipse project with "open project from existing source" using /var/www/html/wiki as the source folder

Enable composer in Project's properties There should be only some 20 errors and 60 warnings. Mostly the errors are XMLProblems and ComposerHook ComposerPack issues which are hopefully not relevant.

Debugging[edit]

Setting Eclipse PHP Debug Preferences[edit]

Personally I think break on first line isn't helpful because it triggers to often.

Setting breakpoints[edit]

Set your breakpoints e.g. in the code e.g. of an extension. Then click index.php and right click "Run Debug as PHP Web Application". You'll be asked for the URL to debug

After clicking "debug" the code will hopefully halt at one of your breakpoints and you can inspect what is going on.

Debug Extension[edit]
