Thanks! I share a comment on the fly, maybe more comments soon after a test :)

Hi @nib - still thanks and you are welcome in updating this patch using something like this:

arc patch D25872
(edits)
arc diff

If you can't, we can eventually help. Thanks!

I've tested this and I'm impressed. You probably have changed my life.

Since the original workflow was completely borked I supposed this is the minimal viable product. But note that running the command twice causes this:

STDERR
fatal: a branch named 'T15187-blabla' already exists

1. Probably in this specific case it should just try to checkout there without creating the branch (?). I also don't think it should behave like arc patch that creates something different.

2. Also, what should happen if the title changes a bit and if I run it again? Maybe it should detect tasks starting with Tsomething and use that?

What do you think about? Note that I'm still impressed and happy as-is lol

Hopefully the latest change will work for you. Now it checks existing git branches matching "T12345*" and if any exist, it will git checkout the first one, else it will create it from the task name.
So that should allow you to change the task title, and to use arc work T12345 as many times as you want without error.

@aklapper Would it make sense to move the branch-naming lines into a function in class ArcanistGitWorkEngine, since it the branch-naming is git-specific? E.g.

public function buildBranchName($task_ref) {
  $task_name = $task_ref->getName();
  // regex, preg_replace, trim, etc
  return $branch_name;
}

Probably yes so it's easier with Subversion and Mercurial in the future (?)

Probably something with "for task" in the name like buildBranchNameForTask($task_ref)
