git absorb: the fixup workflow that sorts itself out

Here's a small thing that has made my git workflow less tedious.

When you're working on a feature branch and get review feedback, you usually end up doing this:

1. Make your fixes
2. Find the commit SHA that needs the fix
3. git commit --fixup <sha>
4. git rebase -i --autosquash

Step 2 is the annoying part. You're scanning git log, copying the SHA, maybe getting it wrong.

git-absorb automates the bookkeeping. You stage your files, run git absorb, and it figures out which commits your changes belong to and creates the fixup commits for you.

git add $FILES_YOU_FIXED
git absorb

If you trust it, --and-rebase squishes everything in one go:

git add $FILES_YOU_FIXED
git absorb --and-rebase

If you want to check first, just run git absorb without the flag, look at what it generated with git log, then run git rebase -i --autosquash yourself.

It's a Rust port of hg absorb, built by Facebook. Install it from the releases page or via cargo.

The workflow it enables is clean: make your changes, stage the files, let the tool sort out which commit gets what. No SHA hunting.

If you're still doing fixups manually, give it a try.
