Magit + gerrit - push to other branch

Question

I am using gerrit. When I want to push my commits, I use following command:

git push origin HEAD:refs/for/master

How can I recreate the same command using Magit?

Answer 1

After a while I managed to have enough time to try to fix it myself.

I don't know of any "out-of-the-box" way to do this; however, you can expand magit to fit your needs.

Firstly, I wrote a function that would push to gerrit:

(defun magit-push-to-gerrit ()
  (interactive)
  (magit-git-command "push origin HEAD:refs/for/master" (magit-toplevel)))

Next, I added it to push menu:

(transient-append-suffix 'magit-push "p"
  '("m" "Push to gerrit" magit-push-to-gerrit))

These two forms are in my init file.

And that's it! Now I can use P m to push to gerrit.

Update: If you want to push a specific commit and not HEAD, you can use this function (also updated with magit-git-command-topdir as referred to in the comment):

(defun magit-push-to-gerrit (source)
  "Push an arbitrary branch or commit to gerrit. The source is read in the minibuffer."
  (interactive
   (let ((source (magit-read-local-branch-or-commit "Push")))
     (list source)))
  (magit-git-command-topdir (concat "git push origin " source ":refs/for/master")))

Answer 2

Use ! to use a generic git command, then you can simple write: push origin HEAD:refs/for/master almost as usual.

There is also a dedicated package for gerrit here: https://github.com/terranpro/magit-gerrit I haven't used it personally however, so don't know exactly how to use it.

EDIT

In a recent version of magit, it is now possible to specify an explicit git refspec from the r subcommand. Thus, to push to the gerrit refspec, simply use:

P r "origin" RET "HEAD:refs/for/master"

Although, this is not really a shortcut since you have to do even more key-presses, but it is available out of the box.
