[Mediawiki-l] changing displayed text for links in category page

[Kraus, Alexander (KBV)]

I'd like to change the text from the links displayed in a category page.

Now, they are displayed in a format like "namespace:articletitle"

How can I change the displayed text for such a link to a format like
"articletitle (namespace)"?

I searched the mediawiki-code to change this and found the function
makeKnownLinkObj in Linker.php.
I'm not sure, where the best possibility to change the code is -
without having any side-effects.

Any help or suggestions would be appreciated.

thanks in advance

Alex
