A small pet-peeve with fetching the latest main on jujutsu is that I like to move all my WIP patches to the new one. That's also nice because jj doesn't make me fix the conflicts immediately!

The solution from a co-worker (kudos to skippyhammond!) is to query all immediate decendants of the previous main after the fetch.

jj git fetch
# assuming 'z' is the rev-id of the previous main.
jj rebase -s "mutable()&z+" -d main

~~I haven't learnt how to make aliases accept params with it yet, so this will have to do for now.~~

Update: After a bit of searching, it seems that today this is only possible by wrapping it in a shell script. Based on the examples in the jj documentation an alias would look like this:

Update 2: After some months of usage across multiple repositories, I've found it better to be clear with the destination since main, trunk or others can be tracked with a combination of repository aliases too.

[aliases]
# Update all revs to the latest main; point to the previous one.
hoist = ["util", "exec", "--", "bash", "-c", """
set -euo pipefail
jj rebase -s "mutable()&$1+" -d "$2"
""", ""]

You can use this to rebase all your WIPs like so:

$ jj hoist <prev_main> <current_main>

If my previous main revision was kz, this is what I would end up doing:

$ jj fetch origin
$ jj hoist kz main@origin
