Thank you that is very nice.

Got me thinking that it would be fun to write some code that would
report file statistics by element.



[O] New org-count-words function

2018-06-12 Thread Adam Porter
Hi friends,

Here's a new function that counts lines, words, and characters in the
region or the subtree at point.  It prints a message like `count-words`
does, like:

Subtree "Heading" has 7 line, 5 words, and 28 characters.

Note that it does *not* count words in heading lines, planning lines,
and drawers, so it gives a more useful count for the "prose" in the
subtree.

Here's the code:

#+BEGIN_SRC elisp
(defun ap/org-count-words ()
  "If region is active, count words in it; otherwise count words in current 
subtree."
  (interactive)
  (if (use-region-p)
  (funcall-interactively #'count-words-region (region-beginning) 
(region-end))
(org-with-wide-buffer
 (cl-loop for (lines words characters)
  in (org-map-entries
  (lambda ()
(ap/org-forward-to-entry-content 'unsafe)
(let ((end (org-entry-end-position)))
  (list (count-lines (point) end)
(count-words (point) end)
(- end (point)
  nil 'tree)
  sum lines into total-lines
  sum words into total-words
  sum characters into total-characters
  finally do (message "Subtree \"%s\" has %s lines, %s words, and 
%s characters."
  (org-get-heading t t)
  total-lines total-words
  total-characters)
#+END_SRC

It requires this supporting function:

#+BEGIN_SRC elisp
(defun ap/org-forward-to-entry-content (&optional unsafe)
  "Skip headline, planning line, and all drawers in current entry.
If UNSAFE is non-nil, assume point is on headline."
  (unless unsafe
;; To improve performance in loops (e.g. with `org-map-entries')
(org-back-to-heading))
  (cl-loop for element = (org-element-at-point)
   for pos = (pcase element
   (`(headline . ,_)
(org-element-property :contents-begin element))
   (`(,(or 'planning 'property-drawer 'drawer) . ,_)
(org-element-property :end element)))
   while pos
   do (goto-char pos)))
#+END_SRC

I think it's an improvement over the functions I've seen that do this.
Hope someone finds it useful.
