Support `git wt -` to switch back to the previous worktree

[ras0q]

Hi @k1LoW , thank you for this great tool!

I would like to suggest adding support for git wt -, similar to cd - or git switch -.

• git-wt stores the previous worktree path
• Running git wt - switches back to that previous worktree.

This would be very helpful for toggling between two worktrees frequently.

What do you think?

I think it's an excellent idea!
While it might not be necessary for my use case, it feels like a natural feature.

The key point seems to be how previous worktrees should be stored.

OMG I never knew cd - was a thing

Just an idea:
If one doen't mind adding unnecessary entries to one's reflog, checking out to the same branch will add an entry to .git/worktrees/{branch}/logs/HEAD. So we can find previous worktree by the second newest record.

I think we need to decide whether we want to store previous worktrees for each shell session (like cd -) or for each repository (like git switch - ). My idea was to store it on a per-repository basis.

Indeed, you're absolutely right.
While repository-based implementation might be more practical, session-based seems more intuitive.

This is a tough decision.

If it matters, my vote goes for per-repository option too as worktree is a repository rather than shell session thing.

I use git wt as an alias for git worktree add -b new-branch ./.wt/new-branch; cd ./.wt/new-branch, so I think the session-based approach would be a good fit here.
