I've kicked around through the site and the wiki, but I can't find what I'm looking for. If someone could aim me that way, they would be my hero for at least a day. Maybe even two. What I'm looking for is what values and functions I can use from Auctioneer. From Chardonnay's (I think) BaseRule example, I've seen stuff like:
Auctioneer.Statistic.GetUsableMedian(key) and Auctioneer.ItemDB.CreateItemKeyFromLink(link)
I'd like to know all the other values I can use, and where they live.
well, built in variables are explained in the wiki.
as for the functions you listed above (and other similar ones), they are included in the "public API" section at the bottom of every LUA code file in auctioneer. please note that there is no official support provided for these functions - if you want to use them, you'd best be prepared to roll up your sleeves and look at the code to at least make an effort at figuring out what they do on your own, first.
Yeah, your best bet is to dig into the code. There is documentation but as always with documentation there's no guarantee that it's correct, complete, or up to date.
