Thanks, your code works as long as the element at point is some kind
of block element.
I have identified the following block elements:
- all elements that end with "-block
- latex-export/environment
- diary
- drawer
- export
- fixed_width
However, I'm trying to write something that works on all elements and
I want my code to continue working even if new elements are added to
org-mode.
It would be ideal if elements had the following additional properties:
- :value-begin
- :value-end
Unfortunately, they don't.
I have come to the following hackish solution:
#+BEGIN_SRC emacs-lisp
(defun org-select-inner-element ()
"Select inner-element.
Return begin and end of inner contents of org-element at point."
(let* ((element (org-element-context)))
;; Element has a value
(if-let ((value (org-element-property :value element)))
;; Try to return begin and end of :value property
(let ((lines (remove "" (split-string value "[\n\r]"))))
(list (save-excursion
(goto-char (org-element-property :post-affiliated element))
(search-forward (first lines))
(match-beginning 0))
(save-excursion
(goto-char (org-element-property :end element))
(search-backward (car (last lines)))
(match-end 0))))
;; Check if element has :contents-begin and contents-end
(if (org-element-property :contents-begin element)
(list (org-element-property :contents-begin element)
(org-element-property :contents-end element))
;; Otherwise select the whole element
(list (org-element-property :begin element)
(org-element-property :end element)))
)))
#+END_SRC
