jj is so good, finally a tool to replace Git. SVN -> Git -> jj

• WolfeReader 11mo ago
  That's an excellent description. I still remember feeling like a badass using Git-SVN on my SVN-based team, and being the only guy who could actually correct bad merges and restore lost data without having to plead to our SVN admin. And now I'm feeling like a badass using jj on my Git-based team :)

  No LFS, submodules, hooks, or new tags means jj has some ways to go before it is a viable replacement for many organizations https://jj-vcs.github.io/jj/latest/git-compatibility/ https://jj-vcs.github.io/jj/latest/git-compatibility/

    Having used git submodules, I see a lack of them as a feature. I honestly think that a script that checks out a specific commit from an external repository, combined with adding the path to the .gitignore is strictly better than submodules.
    • verdverm 11mo ago
      sure, but there are projects that use them already. If jj wants to replace git, it needs to work with people's existing projects without significant changes (ideally none at all) Changing git hosts happens less frequently than changing clouds, which is infrequent. Changing VCS tools is even less frequent than either of those
      • aidenn0 11mo ago
        git doesn't do everything that SVN does, so I don't think that's true.
        • verdverm 11mo ago
          The development world is much different and entrenched than it was when the move from svn -> git happened. Think of all the tooling, integrations, and automation we use these days. That was not happening 15+ years ago. I don't think svn as an analogy holds much water, tbh
          • aidenn0 11mo ago
            Tooling, integrations, and automation (Including CI) were all things we used at my work when we switched from CVS to SVN almost 20 years ago.
            • verdverm 11mo ago
              Some people were, yes, but the scale of this has changed in those 20 years as well

      How do you record the specific commit of the external repository, that was used in a specific commit of your repository?

    LFS sorta works and submodules are just managed by git, and you can create tags with the git CLI just fine. Hooks are a bigger change, though, for sure.
    • verdverm 11mo ago
      Sounds like I still need git for much of this, so jj and the things it does is and additional thing to manage. I've been told intermixing them is not a good idea
      • steveklabnik 11mo ago
        Sure. Use the tools you like! At the same time, not everyone requires those features. All I mean to say is, the degree of support is varied out of the things mentioned, not just "no support for any of them." It's still pre-1.0 software. We'll get there :)
        • verdverm 11mo ago
          The docs say "no" to support for all of those except tags, which is "partial" because jj can check it ou, but not create them, which hopefully is clear in my comment that "new tags" is still a "no" I'm going to take the docs for what they say about support over an HN comment
          • steveklabnik 11mo ago
            You can trivially run `git tag` and create one, or in your forge and then pull it down. Creating one is not directly supported directly in jj's cli, but if you create a tag, it's in the repo just fine.
            • verdverm 11mo ago
              right, but then I'm using git, not jj, so why jj? Why do people believe it's going to replace git if it won't do basic things we need. Why is it hard for jj to create a tag?
