We use BitBucket at our company, which is some source of frustration for us. One of the issues we have with BitBucket is that it seems to lack a decent CLI tool. This means that in order to e.g. create a pull request, you go to the website, click a few times and only then confirm that a PR is really what you want.
Well, after some time I learned that it’s not that bad. When you git push your changes, Git (on the command line) responds with the URL you need to go to create a pull request out of the branch you just pushed. (This is most probably achieved via post-receive or some other Git hook.) Nice.
Well, of course I don’t use Git from the command line – I use Magit. So naturally I wanted Emacs to extract that information for me and open the URL in the browser. It turns out that it was easier than I thought. Using the famous Emacs self-documenting capabilities, I found two commands: magit-section-backward, and, most importantly, magit-process-buffer. (Go check their docstrings to learn what they do, or perhaps confirm your guess.) So, I hacked up a pretty simple function to grab the data from the Magit process buffer and open the PR page in my browser.
(defun magit-open-pull-request-pr ()
"Open the pull request URL if applicable."
(interactive)
(save-excursion
(set-buffer (magit-process-buffer t))
(goto-char (point-max))
(magit-section-backward)
(when
(search-backward-regexp "remote: \\(To create a merge\\|Create pull\\) request" nil t)
(forward-line 1)
(re-search-forward "remote: +" (line-end-position) t)
(browse-url-at-point))))
As a bonus, I modified the first regex in the code above so that the same command works for GitLab (which we also use for a few projects).
I feel like a broken record, but once again Emacs turns out to be an extremely user-friendly environment (provided that the user is a tinkerer kind, of course).
