Forgot to add the code.

#+begin_src emacs-lisp
  ;; Adapted from code posted by Paul Sexton <2011-02-16 Wed 4:51am>
  ;; - Everything now contained in one function
  ;; - Will count correct number of words inside Latex macro

  (defun org-word-count (beg end)
  (interactive "r")
  (unless mark-active
    (setf beg (point-min)
          end (point-max)))
  (let ((wc 0)
(latex-macro-regexp "\\\\[A-Za-z]+\\(\\[[^]]*\\]\\| \\){\\([^}]*\\)}")) ; CHANGED
    (save-excursion
      (goto-char beg)
      (while (< (point) end)
        (re-search-forward "\\w+\\W*")
        (cond
         ((or (org-in-commented-line) (org-at-table-p)) ; CHANGED
          nil)

          (goto-char (match-end 0)))
         ((save-excursion

          (goto-char (match-beginning 2))  ; CHANGED
          (setf wc (+ 2 wc)))
         (t
          (incf wc)))))
    (message (format "%d words in %s." wc
                     (if mark-active "region" "buffer")))))
#+end_src

I am trying to reduce the word count in a document I am writing. The
existing word count functionality for emacs is surprisingly lacking.
I wanted a word count function for org mode which excluded tables and
comments, and ended up writing one myself.

If this function is called with a region highlighted, it counts the words in
the region. Otherwise it counts words in the whole buffer.

It ignores commented lines and tables. LaTeX-style macros such as
\foo{bar,baz} are counted as 1 word, as a compromise (more often than not
they should count as 0, but they do sometimes expand to 1 or more words
in the final document).

Limitations:
- Does not ignore BEGIN_SRC/END_SRC or inline src_* blocks (babel).
   Should be easy enough to add however.
- There is probably a better way of identifying latex macros
   than my 'latex-macro-regexp' below.
- Ignores all org links. I couldn't figure out how to extract "description"
   text from links, but I didn't look very hard.

Improvements welcome.

Paul
