Is there a way to get bash-it/zsh style terminal prompt information about my jj repo?

Hiya, I use bash-it, and it's nice in a git repo to see some git information like the branch name here:

jbarkhuysen at MacBook-Y9JVN in ~/workspace/golang-doc on main
$

Besides telling me I'm in the main branch, it's also telling me I have no uncommitted changes (lack of an asterisk like main*), and mostly importantly that I'm in a git repo at all.

I'd love something like that for jj. Right now it looks like:

jbarkhuysen at MacBook-Y9JVN in ~/workspace/foo
$

foo is a git repo that I cloned with jj. Has anyone got anything that I could use to get some jj info into my prompt?

Brainstorming how that might look... My jj log looks like this:

jbarkhuysen at MacBook-Y9JVN in ~/workspace/foo
$ jj log

Maybe the short-rev?

jbarkhuysen at MacBook-Y9JVN in ~/workspace/foo nptpzqvp
$

Or maybe the short-rev chain to HEAD?

jbarkhuysen at MacBook-Y9JVN in ~/workspace/foo nptpzqvp -> qtvzykvk -> tqtwnrrz
$

Maybe subbing short-rev for branch name if one exists instead?

Maybe you can adapt the starship.rs template into one for bash-it?

Ended up writing a small bash-it plugin for this. Turned out much easier than expected.
