I love this stuff as a hobbyist, but professionally I can't help but think this is all obsolete in the age of agent-driven development. I wish jj was around a decade ago.
Makes me happy to see the influx of jj posts as of late. Great tool. Roughly this workflow is how I convinced a few friends to finally loosen their death grip on git and try something new.
This is something you have to generally handle manually since absorb won't squash hunks with ambiguous targets, but I typically stack these branches and accept the dependency. I have had instances where this has backfired a little bit re: ordering but thankfully with JJ and the very patient little man in my computer named Codex it's easy to reorder them and end up with the same diff
The mega merge wouldn't handle that based on the way the article shows. You COULD have a revset that includes stacked changes, though. That does work and is what I currently do.
It's interesting to see the strange workflows that come from jujutsu users, as someone who works on git workflows.
There's some counterproductive stuff in there from my perspective but at its core you're keeping up a throwaway integration branch, which is helpful practice if you'll ever care about an integration. It's annoying with git because the interface for updating your throwaway integration branch is very clunky and easy to get wrong.
I saw Jujutsu on HN a few days ago and gave it a try. I picked a bunch of it up in just a couple hours and a couple days later I've completely switched to it for all my projects, it's not even close. Git is dead to me.
I just wish Jujutsu supported git tags rather than only supporting bookmarks as branches. And I also wish that Jujutsu supported preserving commit dates during rebases.
One of my absolute favorite things about Jujutsu is how easy it is to manipulate the commit graph remotely without having to manually checkout each commit first. I've been working on some pull requests to their built-in diff editor lately trying to improve the user experience enough that most conflicts will be fixable without having to use a text editor.
Also, the lack of a special staging area means you also never have to fucking stash your changes before you can do practically anything. Your changes always have a place, you can always go somewhere else and you can always come back.
Oh? That's incredibly recent. Thank you for letting me know. As it turns out, I just built jj from source earlier today, so ironically I should already have tags. I'll give it a try.
Re: commit dates, fundamentally those always change when rebasing because you're rewriting the commit object, but we don't touch the author date unless you explicitly reset it with metaedit
Though, I'd be remiss not to mention that this (and any other) jj workflow would be much easier with jjui. It's the best TUI around, not just for jj
I proposed incorporating some of this article into it. https://github.com/idursun/jjui/discussions/644
If anyone is JJ-curious, I also can't recommend the Discord[1] enough. The community is very helpful and welcoming.

I'm still not as smooth at figuring out conflicts on mega-rebase.

There are commands for manipulating tags (jj tag set, jj tag delete), and recently [1] support for fetching / pushing
