  2. Check out https://github.com/martinvonz/jj/ . It's highly inspired by Pijul, among VCSes, and uses a git backing store, so you can use it personally and (mostly) seamlessly interact with any git-only team.

  3. I'm still trying to wrap my head around this one, but jj is interesting: https://github.com/martinvonz/jj

  4. …very interesting system y'all should check out). Sure. I presented about that at Git Merge 2022. https://github.com/martinvonz/jj#disclaimer has links to the slides and the recording from there. I'll summarize the problems we have with…

    comment by sluongng · 2023-06-28 · in Meta developer tools: Working at scale
  6. There's also Jujitsu that looks a bit more interesting IMO: https://github.com/martinvonz/jj Or Pijul if you want to give up on Git compatibility.
    comment by IshKebab · 2023-06-17 · in Gitless: A simple VCS built on top of Git
  7. See https://github.com/martinvonz/jj for a VCS that's compatible with Git and has a simpler CLI with undo functionality and first-class conflicts (you can rebase conflict resolutions, for example). It's what we're planning to replace…

  9. You can give https://github.com/martinvonz/jj a try. It works with git repos. Jj is developed, in part, by a few Mercurial developers.
    comment by ilyagr · 2023-01-22 · in Git-sim: Visually simulate Git operations in your own repos
  10. https://github.com/martinvonz/jj and http://sapling-scm.com/ are good steps in this direction!
    comment by arxanas · 2023-01-09 · in Branchless Workflow for Git
  11. see also, https://github.com/martinvonz/jj which I really have been enjoying wrapping my head around and using. True undo, and no-stage is truly such an amazing experience compared with raw git.

  16. For people who want Git's data model but a better CLI, check out https://github.com/martinvonz/jj . It's a more Mercurial-like CLI but you can use it with existing Git repos. It also includes undo functionality, anonymous branches and…

  17. …given the requirments of the tool. If you're curious how it can be done (IMO), take a look at https://github.com/martinvonz/jj . It's its own VCS but also compatible with Git so individual developers on a team can migrate to it.

  21. …SCM is compatible with Git, you may not have to learn much about Git. That's my hope for my SCM: https://github.com/martinvonz/jj . I agree that it seems very hard for a new SCM to get many users without having good compatibility with Git.

    comment by markstos · 2022-04-12 · in Eden
  25. https://github.com/martinvonz/jj is a promising alternative which fixes many of the design mistakes of Git, but can still interact directly with Git repositories.
    comment by arxanas · 2022-03-26 · in Fossil
  26. There are probably a couple good ways to avoid trying to split `git add -p` with e.g. jujutsu `jj`? https://github.com/martinvonz/jj/blob/main/docs/git-comparis... If CI isn't running tests for every PR, `git add -p` can create pretty…

  28. …`jj git fetch` which branches to import, but I'm not sure yet what the best solution is. See https://github.com/martinvonz/jj/blob/main/docs/branches.md for more information.
    comment by martinvonz · 2022-02-20 · in Jujutsu – A Git-compatible DVCS that is both simple and powerful
  29. Yes, they are supported, and documented at https://github.com/martinvonz/jj/blob/main/docs/branches.md . I need to document better how to use them for common workflows like GitHub PRs. FYI, here's one way to use them with GitHub PRs: 1.…
    comment by martinvonz · 2022-02-20 · in Jujutsu – A Git-compatible DVCS that is both simple and powerful
  30. Yep. Same thing in Jujutsu (the recursive merge is at https://github.com/martinvonz/jj/blob/a6ef792ba66b5b19e75282... ). Probably the biggest difference compared Git there is that it'll still work even if there are conflicts. FYI, this is…

  31. I filed https://github.com/martinvonz/jj/issues/61 about having Nix packages. I should learn about Nix packaging some day, but I'd appreciate any help I can get.
    comment by martinvonz · 2022-02-20 · in Jujutsu – A Git-compatible DVCS that is both simple and powerful
  32. Yes, no staging area. Does https://github.com/martinvonz/jj/blob/main/docs/git-comparis... help address your concern?
    comment by martinvonz · 2022-02-20 · in Jujutsu – A Git-compatible DVCS that is both simple and powerful
  33. …definitely a goal. I think Jujutsu does a much better job at that than Git does. Did you read https://github.com/martinvonz/jj#comprehensive-support-for-r... ?

    comment by mdaniel · 2022-02-19 · in Jujutsu – A Git-compatible DVCS that is both simple and powerful
  36. Note, though, that it depends on libgit2 (which is written in C). (As pointed out by someone in https://github.com/martinvonz/jj/issues/56 .)

  37. …to use the jj backend to get all the feature? Nope, conflicts work with the git backend as well. https://github.com/martinvonz/jj/blob/main/docs/git-compatib... has some info. > To sum up my comment in a TL;DR: To really sell me on a…

  38. …`jj split -r <commit>`, where `<commit>` may be the working copy commit (which is the default). See https://github.com/martinvonz/jj/blob/main/docs/git-comparis... for more examples.

    comment by martinvonz · 2022-01-29 · in Oh Shit, Git?
  43. I'd like to think it was my project ( https://github.com/martinvonz/jj ), but other possibilities include Gitless ( https://gitless.com/ ) or Bazaar ( https://bazaar.canonical.com/ ).
    comment by martinvonz · 2022-01-19 · in Pijul 1.0 Beta
  44. Or my own project: https://github.com/martinvonz/jj . I think https://github.com/Byron/gitoxide also plans to provide a different CLI, but I don't think they've started working on it.
