Support stashing

[modocache]

I want to be able to stash uncommitted changes:

let repository = openRepository(NSURL(fileURLWithPath: "/Users/modocache/Desktop/MyRepo")!)
let index = repository.flatMap { $0.index }
let commit = index.flatMap { $0.stash(message: "Saving some work for another day") }

I'd also like to be able to apply stashed changes somehow. Not sure what that API should look like yet, but suggestions welcome!

We can create a stash thanks to b305354 and 699f411. It turns out a stash creates a commit object.

The next part of this issue would involve applying a stash. Perhaps "applying a stash" would simply mean merging the commit that was created? Is there a way to get a list of stashes, like git stash list? Ideally, we would be able to list all stashes, find the one we want, then apply it.

Hi @modocache!

There are two things related to stashing that I think I can help shed some light on.

With regards to applying a stash, I don't know the specifics, but I'm pretty sure that it's far more complicated than a simple merge. Fortunately it appears that libgit2 will get git_stash_apply and git_stash_pop soon.

With regards to getting a list of stashes libgit2 already has this built in, with git_stash_foreach.

Hopefully this helps,
Ezekiel
