Category:Extensions by hook usage/pl

The  category is the parent category for hook usage categories. Hook usage categories collect together all the articles that make use of a particular MediaWiki hook.

This category is intended to help new (and old) implementers find examples of code that use particular kinds of hooks. It is not intended for listing newly defined hooks. If your extension has added a hook, please add it to the Hook extensions category instead. You may also want to consider adding a brief description of your hook to the Extension hook registry.
