Some commit messages contain sha1 hashes of older commits in order to reference these commits, e.g.:

Fixes: deadbeef

Is it possible to visit the referenced commit from the first commit message?

    I've created an issue for this (and a bit more): github.com/magit/magit/issues/2949. – tarsius Jan 10 '17 at 23:09

I'm not aware of any builtin command that works on an arbitrary hash at point. You can copy the hash, call C-u magit-show-commit, and then yank the hash.

Instead, I use the following command for this purpose.

(defun km/magit-show-commit-at-point (&optional choose-project)
  "Show commit point.
If there is no current project or if the prefix argument
CHOOSE-PROJECT is non-nil, prompt for the project name."
  (interactive "P")
  (if (save-excursion (skip-chars-backward "A-z0-9")
                      (looking-at "\\b[A-z0-9]\\{4,40\\}\\b"))
      (let* ((hash (match-string-no-properties 0))
             (project
              (and (or choose-project
                       (not (projectile-project-p))
                       (not (magit-rev-verify (concat hash "^{commit}"))))
                   (completing-read "Project: "
                                    (projectile-relevant-known-projects))))
             (default-directory (or project default-directory)))
        (magit-show-commit hash (car (magit-diff-arguments))))
    (user-error "No hash found at point")))

I've written this to work with Projectile. It prompts for a project if the hash doesn't seem to belong to the current project or there is no current project. However, you could easily remove those parts, if you don't use Projectile.

  • Thanks, this works, I removed the projectile parts for my usage. It would be nice to work as described by phils, though. – Gregor Jan 10 '17 at 22:43
