Re: The creator of Jujutsu has joined ERSC
#142I like the idea of jujutsu, but I must not operate at a scale where its "killer features" would truly shine. Git hardly ever gets in my way, I have never had to do complex octopus merges or anything like that. It's usually: feature branch, implement, merge, and occasionally fix a merge conflict. JJ seems like it's more for people that like to have tons of active branches that they are constantly switching between whereas I usually only work on 1 thing at a time. I've never thought to myself "git is so frustrating I wish there were something better" because I only use the same 5 commands over and over every day and they never get in my way. Not to mention jj has its own share of esoteric syntax with all the "@--+::" business and I'd have to re-wire my brain to remember those symbols instead of `ref~N`, etc.

I was a skeptic until a few months ago. It’s my daily driver now. I’ve got sizable amount of people committing to the same repo, many are not skilled with git. So I deal with weird crazy “how did you ever get the repo into this state” issues not infrequently.
JJ is just so low friction. The seamless and painless shuffling of commits, working up and down the commit chain without explicit rebasing, unchanging change-ids. The min identifiers in change-ids being highlighted. Being able to make commits and worry about the message later. Snapshots of changes while you are working serving as a tool agnostic undo.
Painless and sensible cli args that are vastly more consistent than git.
Superior conflict handling.
You can “jj undo” anything and it works perfectly.
It’s fabulous.
> "@--+::"
I have no idea what that means and I’ve never had to type anything remotely like it.
The rev specification language is pretty elaborate but you don’t need to know it.

#144This website has unbearable scroll performance on mobile. Is it the animation at the top?
We tested it in mobile, but several people pointed out that we have more performance work to do to make sure that the animation is fast on lower-end hardware. I don't know what phone you're using, but we'll get it fixed regardless.
One more data point--I'm using Firefox on an M1 Mac mini (MacOS 15.7.7), and this web site destroys the responsiveness of this system in a way I have literally never seen before (4+ years) from anything, web site or otherwise.
I opened up Activity Monitor and CPU use looked normal but it showed the GPU was pegged at 100% as long as that page was open.

A few advantages for me, even for the same 5 commands I use over and over:
- undo
- shuffling commits around with squash, split, and rebase is much better than git’s interactive rebase
- make commits without having to come up with a branch name (I might make three versions of the same change in parallel to see how they compare)
I see git is working on adding some of this under the history command. The revset language is really not esoteric: @ is head, @—- is two behind head. That’s about it.
Part of it is that the sorts of shuffling I used to avoid because they were a pain in git (so I didn’t feel I needed them improved) are so easy in jj that I do them all the time.

#147Earlier quoted context omitted.
I absolutely love jj (just check my HN comment history). One thing I'd love to see in jj though that git does better is copy tracking. If somebody renames a file upstream, and you go to rebase your commit that touches that file onto main, jj doesn't handle this very well compared to git. Do you have any idea if this is coming to jj soon?
Do you happen to have or know of any good open source projects on any public platform like GitHub, gitlab or Codeberg, that uses Jujutsu/jj?
jj uses git as a backend. None of those need to "use" jj. You can use jj in an existing git repo, with your git wielding friends.
Re: The creator of Jujutsu has joined ERSC
#148Badass!!! Congrats. I love JJ’s mental model. Its so much less opionated and lets me do what I want. Want to make 5 versions of the same commit? Easy. Need to push out a change asap without having to pre create a branch, stash your changes, yadayada. Jj just adapts.
Once you start thinking in jj it becomes frustrating having think back to use GitHub as a code repo.

#149Earlier quoted context omitted.
I'd argue that the reason a lot of developers have not learned git in depth is because it's actually kind of terrible from a UX standpoint (lots of inconsistent naming of things and somewhat leaky abstractions), and that Mercurial faced an uphill battle in large part because it lacked compatibility with what people were already using. I haven't used Mercurial, but from what I've heard quite a lot of how jj does thing…
> I'd argue that the reason a lot of developers have not learned git in depth is because it's actually kind of terrible from a UX standpoint Not really. I remember my early years with git and the favt was that I never needed more than clone, add, commit, pull and push. While I’ve done some mistakes that got ne to learn more, especially with creating branches and undoing. I’ve never needed a lot, even when I started u…
I honestly kind of think your experience is in favor of the GP’s assessment.

> git can do everything jujutsu can do (otherwise, jujutsu couldn't work with git). FWIW I think it's a bit more nuanced than that. As a trivial counter example Git does not currently have a way to store conflicts inside commits[1], which is one of our major features. The way this works is that we basically store the sides of the conflicting trees in the Git object database (and another conflicted tree pointing to al…
> As a trivial counter example Git does not currently have a way to store conflicts inside commits[1], which is one of our major features. Yes, I like how jj does it! Did a big `git rebase -i` yesterday and I felt stressed up, almost a bit angry, when there were some conflicts and I wasn't sure if I'd resolve all of them before it was time to leave, and work more later from a different laptop. But with jj, no stress:…
And you can deal with them in any order, bit by bit, or by adjusting things in earlier commits. I no longer fear rebase conflicts.
