I wanted to always have up to date hash of contents of the directory after any change to use as a cache key. Started to list files, hashing them only to realize jj is already constantly doing that 😬
$ jj log --limit 1 -r "ancestors(@)" -T "self.commit_id()" --no-graph src/
# git hash
$ jj log --limit 1 -r "ancestors(@)" -T "self.commit_id().short()" --no-graph src/
# short hash
One of my most used commands gets better and better - jj prpr.
When using “jj”, I’m on the squash/changes as TODO workflow:
jj sq, or better: jj absorbThis handles the local part, what about the PRs? I don’t want to repeat my commits
in GitHub PR description. It’s already in my commits! This was how prpr was born.
jj prprfirst change on top of trunk()?
Confirm/skip AI code review for quick sanity check
Push bookmarks in the stack
No PR? Create PR via gh CLI
PR exists?
Link to draft PR is now in clipboard. PR description is created out of commit messages.
There’s a lot of asterisks here and little QoL fixes like handling multiple changes,
stacking PRs and more. I freaking love it. At some point hopefully jj sync
will be there and it will get even better.
I asked Claude to describe the full flow in ASCII:

Just sharing it out there, little QoL commands that are fun and easy. I had the initial version working in bash in ~2024 but in 2025 I let Claude rewrite it in fish-shell, and add all the little improvements that really made it enjoyable.
