There is git-fixup, which provides the 'git fixup' command that makes suggestions to which commit the currently staged changes should be added.

git-fixup will add fixup! commits, so it still needs the mentioned 'git rebase -i --autosquash' afterwards. Usually you do not even need to give it a specific commit if your branch is set to track an upstream branch.

Still not quite the same, because absorb splits up your working directory changes into all relevant commits, as deduced by diff context.

Staged or unstaged? Sounds interesting, will give it a try. Thanks for the details.

Dipped into it.

Staged changes, excluding renames.

So git-fixup and git-absorb will now happily live together for the moment on my box.

Made a good first impression, thanks again for the reference.
