Add git amend -i for a TUI

[Waylon Brown]

Description of the bug

For git amend the docs state that if I want to amend only some changes, I should add those to the staging area first.

I then expected there to be git amend -i - similar to git record -i - where I can choose with the TUI which changes to stage. This would be great so that I don't need to create a new commit each time I want to use the TUI to add only some changes.

I agree that this would be useful, but I don't have any plans to work on it. You could try https://github.com/martinvonz/jj which does have a jj amend -i command.

Out of curiosity, why is it this isn't something that's planned? Is it too much work to integrate the existing TUI with amend? The TUI is really great - I think it'd make branchless a bit more intuitive to be able to use the TUI in other places since it's working with record.

Unfortunately jj is incompatible with my repo.

For ex. I can accomplish it w/ a couple commands, so I'm wondering if much of the internals could be reused here.

# git stage interactive
# Select changes in working directory to stage.
function gsi {
	# Using && \ to abort if exiting TUI.
	# Commit changes to keep
	git record -i -m "Temp." && \
	# Move changes back into working directory, which has prev-commited changes staged.
	git reset --soft HEAD~
}

# git amend interactive
alias gai="gsi && git amend"

I just haven't had time to work on it. It should be reasonably straightforward if you want to work on it (but not trivial, because you have to synthesize the partial commit — you can see how it's done here:

git-branchless/git-branchless-record/src/lib.rs

Line 304 in ed35cde

 let (selected, _unselected) = file.get_selected_contents(); 

).

You would also want to support the --merge and --reparent options that already exist for git amend.
