Given this tree :
* TODO Main [#2]
** DONE Child1 [#0]
** TODO Child2 [#3]
** TODO Child3 [#4]
*** TODO Subchild1 [#1]
*** TODO Subchild2 [#2]
I would like that the priority of parent headings be automatically set to the highest
priority among its note done children.
So, in previous example, as soon as Subchild1 priority is set to 1 (0=highest, 5=lowest),
then priority of Child3 should be replaced by 1 (instead of 4) and priority of Main should
also be changed to 1 as this became the priority of its child Child3, but it would not
be set to 0, priority of Child1, as this task is done.
The reason for this it that usually a project is a main heading, which is split in
subtasks and, I want the overall project priority to reflect the highest priority of its
not done tasks.
To do so, I need to create a recursive function :
(adjust-priority ()
(apply-on-child #'adjust-priority)
(set-priority (if-child (collect highest-priority))))
and apply this function to the top level heading whenever a change in priority occurs in
its children.
But this involves org skills a bit beyond my understanding, I wonder if you could give
me some piece of advices on how to do that :
- is there a suitable hook for this function ?
- when in a given tree, how can I select the top level heading ?
- when at a given heading, how can I change programmatically the priority ?
For this latter question, I tried (org-entry-put nil "PRIORITY" "2"), but it replied that
org-priority: Priority must be between ‘0’ and ‘5’

No hook, but you can advice `org-priority' using :after advice.

(while (org-up-heading-safe))
Try to play with this using M-: with point at different headings.

(org-priority 1), for example.

That's because `org-entry-put' converts the argument into number,
assuming a single-character string like "A". This is probably a bug.

Here is something working, probably not yet all cases proof
(defun local/set-priority1 ()
(org-with-wide-buffer
(when (org-goto-first-child)
(let ((ls (remove nil (cl-loop collect (local/set-priority1) while (org-goto-sibling)))))
(outline-up-heading 1)
(if ls (org-priority (seq-min ls)))))
(if (eq 'todo (org-element-property :todo-type (org-element-at-point)))
(string-to-number (org-entry-get nil "PRIORITY")))))
(defun local/set-priority2 ()
(save-excursion
(outline-up-heading (- (org-element-property :level (org-element-at-point)) 1))
(local/set-priority1)))

I recommend using org-* functions, when you can. outline-* functions are
not always compatible with Org.

Note that parent heading may or may not be just one level lower.
Consider
* heading 1
****** child
