Opening Sourcegraph from Emacs

Sourcegraph is super useful when browsing through code and dependencies, there is currently no plugin for emacs, but it is pretty easy to configure git-link to do the trick as @sqs pointed out to me on Twitter.

This is all the configuration to make git-link work as expected, and it should be pretty generic.

Emacs Markdown list DWIM

Markdown has multiple types of lists, and in my mind checking items from those list means different things depending on the type.

- [ ] this item is open
- [x] this item is close
- this item is also open
- ~~this item is also close~~

For checklists I want the box to be checked when I toggle the item for, others I want the item to be crossed out via strike-through. All of those actions already exist in Emacs Markdown-Mode, but they are different depending on the list, I want Emacs to do what I mean no matter the list so I added this

(defun coder--markdown-toogle-list-item-dwim ()
    "Toogle the current list item depending on the type do the right thing.

1. When it is not a markdown list, ignore
2. When the list is a checklist indicated by [ ] check the checkbox
3. When the list is a normal list, strike-through the current item
4. When the item already has strike-through applied, un-strike it"
        (when-let ((bounds (markdown-cur-list-item-bounds)))
          ;; move to the beginning of the item after the list marker
          (goto-char (cl-first bounds))
          (forward-char (cl-fourth bounds))

          (cond ((looking-at "\\[[\s-xX]\\]") (markdown-toggle-gfm-checkbox))
                ((thing-at-point-looking-at markdown-regex-strike-through) (markdown-insert-strike-through))
                (t (progn
                     (set-mark (point))
                     ;; remove trailing whitespace from line first, this
                     ;; otherwise breaks strikethrough rendering

Happy markdown editing!
