How to obtain the headline level from org-element-at-point

How to obtain the headline level from org-element-at-point

[Jeremie Juste]

Hello,

Interleave-mode https://github.com/rudolfochrist/interleave, is a very convenient tool for writing notes in associated
with pdf. It uses org-mode for this purpose.

I recently noticed that in the case where I want to write notes for
multiple pdf in a singlie org file, I have to use the level 1 headline

* Notes for CS103
  :PROPERTIES:
  :INTERLEAVE_PDF: cs103.pdf
  :END:


I would like to have the possibility of using any headline level for
this purpose but my org-fu is weak.

I think it boils down to this function in interleave-mode mode where
(org-element-type headline) checks only for level 1 headline.


#+BEGIN_SRC elisp
(defun interleave--headline-pdf-path (buffer)
  "Return the INTERLEAVE_PDF property of the current headline in BUFFER." 
(with-current-buffer buffer 
  (save-excursion 
    (let ((headline (org-element-at-point))) 
      (when (and (equal (org-element-type headline) 'headline) 
		 (org-entry-get nil interleave--pdf-prop)) 
	(setq interleave-multi-pdf-notes-file t) 
	(org-entry-get nil interleave--pdf-prop))))))

#+END_SRC


Can anyone see a way around it ?

Best regards,

Jeremie

what do you mean it only considers level 1 headlines? It seems to work on
all headlines for me.

The email subject doesn't seem related to the body you can get the level
like this.

(org-element-property :level (org-element-at-point))

Hello,

Thanks for the reply.
> what do you mean it only considers level 1 headlines? It seems to work on all headlines for me.
I mean that interleave-mode doesn't find the pdf path if I use the
following configuration. That is property at level 2 headline.

     * Literature  
     ** Notes for CS103
        :PROPERTIES:
        :INTERLEAVE_PDF: cs103.pdf
        :END:


> The email subject doesn't seem related to the body you can get the level like this.
I was thinking that the function looks at the property of level 1 level
only. am I wrong ? I filed an issue
https://github.com/rudolfochrist/interleave/issues/44  and the
maintainer seems to have confirmed it.

Thanks for the command. I was hoping to understand more this issue with
it. Will post a reply if I find anything interesting.

Bests regards,

Jeremie

There is nothing in that function that limits it to level 2 headings.
The only way you would not get the property is if you are on the level
one heading. It will not look down into the subheading for the property.
