Hello,
I, an Emacs Lisp newbie, want to get a list of all top-level headings of the current buffer. My approach so far is:
(defun test-org-map()
(interactive)
(setq headings '())
(org-map-entries (lambda ()
(setq current-header-item (org-element-property :title (org-element-at-point))
(message "Header: %s" current-header-item)
(message "Is String: %s" (stringp (org-element-property :title (org-element-at-point))))
(setq headings (append current-header-item headings))
)
"LEVEL=1"
)
(dolist (heading headings)
(message "Header Item: %s" heading)
)
)
This gives the otput:
Header: AAA
Is String: t
Header: BBB
Is String: t
Header Item: 66 [3 times]
Header Item: 65 [3 times]
so basically the (org-element-property :title (org-element-at-point) does exactly what I want, but building the list does not what I want. I suppose that comes from a fundamental misunderstanding of how strings work in elisp.
I would appreciate a short explanation (or pointers) why this does not work. And of course, I am very open to completely different, likely better, approches to that simply problem!
Thanks,
Florian
