Subject: Re: How to compute the number of headlines under the given headline?
Date: Sat, 31 Jan 2015 09:37:34 -0500 [thread overview]
Message-ID: <m2egqb2ez5.fsf@andrew.cmu.edu> (raw)

What about:
* Count headlines in current level
#+BEGIN_SRC emacs-lisp
(save-restriction
(org-narrow-to-subtree)
(1- (length
(org-element-map
(org-element-parse-buffer)
'headline
(lambda (x) 1)))))
#+END_SRC
#+RESULTS:
: 5
** one
** two
*** three
**** four
** five
This counts the headline you are in, so I subtract one from the total
count.
