I want to make an addon who is yelling something when my trinket proc. I read this forum and can't get any tuto or something else to learn to write an addon with ace (link for "WelcomeHome" seem don't working).
Where can I found something to learn coding with ace ?
1. Post in the right forum. This forum is for technical discussion of the Ace3 framework itself. Your post belongs in the "Lua Code Discussion" forum. I've moved it, but please read the forum descriptions in the future. If you're confused, look at some of the topics in the forum. If you're still confused, just post in the General forum.
2. Find a small addon that does something similar to what you want to do. Look at its code until you understand it. Use wowwiki.com and wowprogramming.com to help. Ask here with specific questions if you can't figure something out.
Yes, there is.

There are very few errors in Blizzard's XML. They are all well-formed and most can be validated with the provided Schema. Blizzard_TradeskillUI.xml has a validation error (<Size> is used in <Anchors>, which is not allowed).
Also, some Templates are used incorrectly: in FriendsFrame.xml, The $parentSummonButton button are declared as <Button>, but use ActionButtonTemplate as a template, which is a <CheckButton>.
