For this, the package [[https://github.com/sshaw/git-link][=git-link=]] is great. - -To integrate sourcegraph and =git-link=, the [[https://github.com/sshaw/git-link#sourcegraph][documentation]] recommends adding a remote entry named =sourcegraph= in the repository, like this: - -#+begin_src sh -git remote add sourcegraph https://sourcegraph.com/github.com/sshaw/copy-as-format -#+end_src - -The next time you run =M-x git-link= in a buffer, it will use the URL associated with that remote. That's works great, except that now you need to add this for every repository. Instead, for my usage, I came up with the following solution: - -#+begin_src elisp -(use-package git-link - :ensure t - :after magit - :bind (("C-c g l" . git-link) - ("C-c g a" . git-link-commit)) - :config - (defun fcuny/get-sg-remote-from-hostname (hostname) - (format "sourcegraph.<$domain>.<$tld>/%s" hostname)) - - (defun fcuny/git-link-work-sourcegraph (hostname dirname filename _branch commit start end) - ;;; For a given repository, build the proper link for sourcegraph. - ;;; Use the default branch of the repository instead of the - ;;; current one (we might be on a feature branch that is not - ;;; available on the remote). - (require 'magit-branch) - (let ((sg-base-url (fcuny/get-sg-remote-from-hostname hostname)) - (main-branch (magit-main-branch))) - (git-link-sourcegraph sg-base-url dirname filename main-branch commit start end))) - - (defun fcuny/git-link-commit-work-sourcegraph (hostname dirname commit) - (let ((sg-base-url (fcuny/get-sg-remote-from-hostname hostname))) - (git-link-commit-sourcegraph sg-base-url dirname commit))) - - (add-to-list 'git-link-remote-alist '("twitter" fcuny/git-link-work-sourcegraph)) - (add-to-list 'git-link-commit-remote-alist '("twitter" fcuny/git-link-commit-work-sourcegraph)) - - (setq git-link-open-in-browser 't)) -#+end_src - -We use different domains to host various git repositories at work (e.g. =git.$work=, =gitfoo.$work=, etc). Each of them map to a different URI for sourcegraph (e.g. =sourcegraph.$work/gitfoo=). - -=git-link-commit-remote-alist= is an [[https://www.gnu.org/software/emacs/manual/html_node/elisp/Association-Lists.html][association list]] that takes a regular expression and a function. The custom function receives the hostname for the remote repository, which is then used to generate the URI for our sourcegraph instance. I then call =git-link-sourcegraph= replacing the hostname with the URI for sourcegraph. - -Now I can run =M-x git-link= in any repository where the host for the origin git repository matches =twitter= without having to setup the custom remote first. |
