Custom function for killing the thing at point

Custom function for killing the thing at point

[Rodrigo Morales]

I just created this function for copying the thing under the cursor (it
works for some #+BEGIN blocks and links). I think it would be useful for
others, so I'm creating this post for getting feedback on the Elisp code
and sharing it to those interested.

#+BEGIN_SRC elisp
(defun my/org-kill-thing-at-point ()
  "Kill the thing at point.

The following things are currently supported

- #+BEGIN_SRC <<any>>
- #+BEGIN_EXPORT <<any>>
- #+BEGIN_EXAMPLE <<any>>
- #+BEGIN_COMMENT
- Org links (the description is not copied)"
  (interactive)
  (let* (content
         (element (org-element-context))
         (type (org-element-type element)))
    (cond ((or (eq type 'src-block)
               (eq type 'export-block)
               (eq type 'example-block)
               (eq type 'comment-block))
           (setq content (plist-get (cadr element) :value)))
          ((eq type 'link)
           (setq content (plist-get (cadr element) :raw-link)))
          (t
           (error "The element at point couldn't be copied.")))
    (my/kill-new content)))
#+END_SRC

#+BEGIN_SRC elisp
(define-key org-mode-map (kbd "C-c c") 'my/org-kill-thing-at-point)
#+END_SRC

Hi Rodrigo,

Thanks for sharing, it seems interesting and useful. But I think this
function is missing in your post: `my/kill-new'.

Best regards,

Juan Manuel

I would fall back to region between :begin and :end of the element.

Also, it might be helpful to print a short message about what element
have just been copied.

alternatively, fall back to org-mark-element. I am not sure what
differences in what you are trying to achieve and this are, but this should
cover all org elements:

(defun org-kill-element ()
  (interactive)
  (org-mark-element)
  (call-interactively #'kill-region))

Sounds more reasonable as a default. (org-mark-element) will mark
everything including affiliated keywords and post-blank empty lines.
(:begin .. :end) will not include the affiliated keywords and extra
blank lines.
