Could you spell out slightly more what you mean? I'm not 100% sure what "get" means.

I think they mean what other branch some branch was originally branched off from.

  Yes. I could see confusion about the term "parent" but get? IDK what the confusion is there.

    It was just like, in what context? To print a log? To rebase something? "get" is not a command exactly. That's it. Some of it is also what a "branch" means to different people can mean different things: https://jvns.ca/blog/2023/11/23/branches-intuition-reality/ https://jvns.ca/blog/2023/11/23/branches-intuition-reality/ But yeah, as others have said, not really possible in a general way, sadly.

      get as in find, retrieve, identify, etc. Im talking about a use-case not a git feature.

        Yeah now I got it! Just me being a bit confused, it's a me thing, not a you think :)

    If you're looking to model git branches as much as possible with jj bookmarks and assume that: - the working copy has a bookmark pointing to it - there's some ancestor with a bookmark - there's a single linear path between the two with no other bookmarks in between Here's an example that represents a branch containing 3 commits named "bookmark-05ff" branched off of "bookmark-6825". > jj log -r y:: -T builtin_log_redacted @ urplyywu user-482a 2025-10-23 13:24:52 bookmark-05ff a334e2e1 │ (empty) (redacted) ○ lxxtnlxw user-482a 2025-10-23 13:24:46 git_head() 7e32fa6b │ (empty) (redacted) ○ omktyuos user-482a 2025-10-23 13:24:13 7668b0bb │ (empty) (redacted) ○ ykzktoux user-7b7f 2025-10-23 13:23:47 bookmark-6825 98bfcbde │ (empty) (redacted) ~ In this case, the following log would get you the commit pointed to by "bookmark-6825": > jj log -r 'latest(ancestors(@) & bookmarks(), 2) ~ @' -T builtin_log_redacted ○ ykzktoux user-7b7f 2025-10-23 13:23:47 bookmark-6825 98bfcbde │ (empty) (redacted) ~ I'm using the builtin_log_redacted output template. Normally you'd have actual bookmark names, descriptions, user, etc. Also note this bakes in a lot of assumptions and is brittle. As many others have said, it’s not generalizable.
