What to do with read-only file? diff?

[ddickstein]

In cases where vim crashes and a newer swapfile exists, a readonly version of the file opens. I understand this is by design. What if I want to see the swapfile, or override the readonly version with the new one? Ideally whenever this happens I'd like 2 panes to open, one with the swapfile and one with the old version, and be able to do a side-by-side comparison and pick between them. What's the best way to achieve this?

Seems like the appropriate thing would be to call :recover. Almost everything I edit these days is under Git so I can sort of cheat and just write the recovery out, exit and use git diff to see if I really want it or not. Vim probably can do some of this on its own, but I use what I know. 🤷‍♂️
