Hi. I've been using this for a while and find it very handy.
If people like this and want it in Org Mode, I'll do the rest of the work to
package it up as a patch, with ChangeLog entry, NEWS, etc, and post it here for
review before committing.
To try it out, just evaluate both functions and then run
`M-x org-display-headings-to-point'
from somewhere deep in an org subtree. Comments/feedback welcome.
Best regards,
-Karl
(defun org-headings-to-point ()
"Return all the Org Mode headings leading to point."
(when (not (eq major-mode 'org-mode))
(error "ERROR: this only works in Org Mode"))
(let ((headings (list (org-heading-components))))
(save-excursion
(save-match-data
(save-restriction
(widen)
(while (org-up-heading-safe)
(setq headings (cons (org-heading-components) headings)))))
headings)))
(defun org-display-headings-to-point ()
"Display Org Mode heading titles from level 1 to current subtree.
Display each title on its own line, indented proportionally to its level."
(interactive)
(let* ((heading-titles (mapcar (lambda (heading)
(nth 4 heading))
(org-headings-to-point)))
(level 0)
(hierarchy (mapcar (lambda (title)
(prog1
(if (zerop level)
(concat "• " title)
(concat "\n"
(make-string (* level 2) ? )
"→ " title))
(setq level (1+ level))))
heading-titles)))
(display-message-or-buffer (string-join hierarchy))))
