-I use [sourcegraph](https://sourcegraph.com/) for searching code, and I sometimes need to share a link to the source code I'm looking at in a buffer. For this, the package [`git-link`](https://github.com/sshaw/git-link) is great.
-
-To integrate sourcegraph and `git-link`, the [documentation](https://github.com/sshaw/git-link#sourcegraph) recommends adding a remote entry named `sourcegraph` in the repository, like this:
-
-```bash
-git remote add sourcegraph https://sourcegraph.com/github.com/sshaw/copy-as-format
-```
-
-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:
-
-```lisp
-(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))
-```
-
-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 [association list](https://www.gnu.org/software/emacs/manual/html_node/elisp/Association-Lists.html) 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.
