Li-AutoRepair is a World of Warcraft addon that repairs your gear automatically when you open a window with a repair merchant.

First it will attempt to repair using guild funds, if that doesn't work, it will repair using personal funds. If it was successful it will tell you what your calculated durability was and how much gold it costed you.

That's it! There is nothing to configure, just install it, and it works the same on any character you play on.

This project can be found on GitHub if you think you want to make it work better or add features to it.
