Hi all,
as I mentioned, I'm writing a simple exporter. However, I stumbled on
something apparently simple. How to get the current list level within
org-whatever-item transcoder?
TIA,

By inspecting values of org-whatever-item's arguments, I found out one
way: by checking the amount of indentation in :bullet. Is it reliable?

Ooops, my bad. Indentation is stripped from :bullet.
So, what do I do?

I ran into this problem once; the solution I found was to just walk up
the AST via org-export-get-parent until you run out of parents.
Something like this should work (untested, and probably needs to be
tweaked, as my Elisp is a little rusty):
(defun find-depth (element)
"Find the depth of a (list) element during export."
(let ((parent (org-export-get-parent element)))
(case (org-element-type parent)
('item (1+ (find-depth parent)))
('plain-list (find-depth (org-export-get-parent parent)))
(t 1))))
Hope that helps!
Best,
Richard

Sure it does! I'm ashamed I didn't think about this myself. Here's my
take (I assume that ITEM is a plain-list item):
--8<---------------cut here---------------start------------->8---
(defun org-item-get-level (item)
"Get the level of ITEM, which should be an item in a plain
list. Levels are indexed from 0."
(let ((pparent (org-element-property :parent (org-element-property :parent item))))
(if (eq (org-element-type pparent)
'item)
(1+ (org-item-get-level pparent))
0)))
--8<---------------cut here---------------end--------------->8---
It is a bit less general (and probably a bit faster), but for
a plain-list item transcoder the generality doesn't matter.
