gh pr create - is it possible?

[pweiskircher]

Hi! Love jj!

With git, I had a little gh alias that created a PR from my branch with certain labels set. This is currently not possible as far as I can see - gh doesn't know on which branch it is. Anyone ran into this problem yet and found a possible solution?

Can you look at these to see if your problem is addressed?
Better workflow for reviewing and editing GitHub PRs? #5500

I did see #5500 and that didn't help me. I'm going to subscribe to #4555, though! That sounds like it might solve my problem in the future, at least!

You can use the GitHub CLI per our docs here https://jj-vcs.github.io/jj/v0.28.2/github/#using-github-cli

I'm using jj with my git repo colocated so this already works. I still get things like:

❯ gh pr view
could not determine current branch: failed to run git: not on any branch

[PhilipMetzger]

yes, since you're always in detached HEAD mode as described in https://jj-vcs.github.io/jj/v0.28.2/github/#working-in-a-git-co-located-repository. But since the gh CLI relies on always being on branch, it fails there.

Yup! I was mostly wondering if someone knew a way to make this work or has some workaround for it.

[PhilipMetzger]

there have been a/are various feature requests to make jj behave like its on a given branch but there's no simple workaround for it.

If gh is the GitHub CLI, there is a --head flag that lets you specify which branch you want to use to create the PR.

$ jj bookmark set my-feature -r @-
$ jj git push
$ gh pr create --head my-feature

[pweiskircher]

Nice! I didn't know about that one! Thank you!

I wrote a script that does this slightly more automatically. The initial version took a revision, and automatically used an existing bookmark or prompted for a bookmark name as needed.

The latest version is a little more fun: if there is a bookmark between the tip revision and main, it asks you which one you want to use as the base of the PR, and then it generates a branch name for you based on the diff and log.

In the simple case of a PR of @- directly on main with no bookmarks in between, it's just jprc and press enter to confirm the generated branch name.

I have the following alias in my .config/gh/config.yml file:

aliases:
    pc: "!jj git push -c \"all:$1\"; for c in $(jj log --no-graph -r \"$1 & mutable()\" -T \"change_id ++ '\n'\"); do echo creating PR for $c; gh pr create --head $(jj bookmark list -r $c -T name) --base $(jj bookmark list -r \"heads(::$c- & bookmarks())\" -T name) --fill; done"

You run gh pc <revset> and it will use git push -c to auto push branches for all of your changes in that revset, and for each it will create a PR whose base is the previous bookmark. You might want to drop the base logic if you're not interested in that

Oh, awesome! Something like this was what I was looking for. Much appreciated!
