This page documents a user-defined function that you can copy and paste into your addon. Replace <PREFIX> with your AddOn's prefix to avoid conflicts between different versions of these functions.

These are cut-and-paste functions that you can use in your addons, submitted by WoWWiki contributors. Please see User defined macros, User defined modules and AddOn defined functions for additional snippets and useful ideas.


The following functions aim at extending the information WoW API provides; some are provided by specialized addons rather than being copy/pastable.
