Unexpected set differences with setkeys about jd HOT 2 CLOSED

@duallain the setkeys option determines how the identity of an object should be determined. So -setkeys "column-name" means "two objects are the same one if the value under column-name is the same". So you can flip around the order of the rules but you'll get the same result. jd will compare the columna objects and provide a diff. And it will compare the columnb objects and provide a diff.

I can see how the name "setkeys" could be confusing! I've been thinking of adding a feature to ignore / include certain fields and calling it "masking". I think that's what you were expecting. What could I call "setkeys" instead that would be more clear? How about "idkeys"? I'm working on a v2 API so I can rename it there.

Ahh, I think I understand.

I think the name is ok, all the alternatives seem clunky as well. Not that sure it helps much to rename, but I do like including id in the name, that does help. Maybe objectIDKeys (or setIDKeys)?

Maybe a few more words in the readme to explain what's going on would help. I made a quick PR to try and capture this understanding -- #75

🤞 I've correctly understood what you're saying, and wrote it up reasonably as well. Closing this issue since I think you took care of my request to understand already.
