Colocated repos with multiple workspaces?

[kwiberg]

🖖,

When I use jj workspace add in a colocated Jujutsu repo, I get a new workspace with a .jj/ dir but no .git/ dir—that is, only the primary workspace is colocated.

It feels like this might be fixable with Git worktrees, by giving each Jujutsu workspace its own colocated Git worktree. Has anyone attempted to do this?

Yes, in #4644.

There's no good way to hack it until it's an official feature, because you need jj to keep the git worktree's index up to date and it won't do that today.

Thanks! This answers my question exactly.
TL;DR: Although that PR has been open for almost a year, @ejpcmac recently took over the work started by @cormacrelf, so it looks like it may be picking up steam. ❤️

Hello @kwiberg, just a head’s up to say I’ve been a bit busy AFK for the end of the summer and did not finish the rebase yet. It turned out a little bit more difficult than anticipated because some code has changed in a way that is breaking for the original changes to work.

I also very much want this feature myself, and would like to invest some time in Jujutsu in the long run. This then remains one of my prio OSS work for the weeks to come.

Use case: nix flakes commands like nix develop refuse to work unless they see a .git. Reproducible development environments are very useful.

Yes, I’m a Nix user myself and that’s precisely why I want to see this land. I have at least 6 hours planned to work on this feature this week. I’ve spent last week reading a lot of code and concepts and I’m starting to feel much more confident in rebasing #4436 and having a plan forward :)

For those interested, I have created a tracking issue for this feature and its associated work: #8052. I will post updates on the work in the tracking issue.
