I recently migrated to PricePer from an extremely out of date non-Ace PriceEach.
One option that I would like to control is the ability to hide the per-item calculation of the "bid" price; I only want to see the per-item "buyout" price. (I find the display of the bid price to be distracting when eyeball-grep scanning bargains that I can purchase immediately.)
I whipped up a small patch to PricePer to add a new option "showbid":
/priceper showbid Toggles whether the per-item bid price is displayed.
Basically the diff file just shows the lines added/changed and removed line by line...
iirc you can use something line WinMerge http://winmerge.org/ to merge the changes into the PricePer lua files. Alternatively you can just open the diff file with a text editor (Notepad, Notepad++, EditPlus... whatever) and open the .lua files for Price Per and make the changes manually.
I gave this a shot but /priceper doesn't seem to be a valid registered slash command. Course then I went back to r36848 before I added the diff and noticed the slash command didn't work for me in the first place.
I'd like to thank the author of this addon. About a year ago when auctionit worked, they had price per item. Most useful. Why would anyone want to do the math for each item in their head? I just found priceper and can get the same functionality.
