Subject: Re: Context-sensitive word count in org mode (elisp)

Message-ID: <loom.20110217T002249-206@post.gmane.org> (raw)

Thanks for all the suggestions. Here is version 2.

- ignores source code blocks
- ignores tags and TODO keywords in headings
- ignores footnotes by default (option to force counting them)
- skips any sections tagged as not for export
- option to count words in latex macro arguments (they are ignored
  by default)

I would still like to count hyperlink descriptions but am not sure
how -- is there a function that fetches the description of the hyperlink
at point?



(defun org-word-count (beg end
                           &optional count-latex-macro-args?
  "Report the number of words in the Org mode buffer or selected region.
- comments
- tables
- source code blocks (#+BEGIN_SRC ... #+END_SRC, and inline blocks)
- hyperlinks
- tags, priorities, and TODO keywords in headers
- sections tagged as 'not for export'.

The text of footnote definitions is ignored, unless the optional argument
COUNT-FOOTNOTES? is non-nil.

If the optional argument COUNT-LATEX-MACRO-ARGS? is non-nil, the word count
includes LaTeX macro arguments (the material between {curly braces}).
Otherwise, and by default, every LaTeX macro counts as 1 word regardless
of its arguments."
  (interactive "r")
  (unless mark-active
    (setf beg (point-min)
	  end (point-max)))
  (let ((wc 0)
	(latex-macro-regexp "\\\\[A-Za-z]+\\(\\[[^]]*\\]\\|\\){\\([^}]*\\)}"))
      (goto-char beg)
      (while (< (point) end)
        (re-search-forward "\\w+\\W*")
         ;; Ignore comments.
         ((or (org-in-commented-line) (org-at-table-p))
         ;; Ignore hyperlinks.
         ;; TODO need to count text of the link's description.
         ((looking-at org-any-link-re)
          (goto-char (match-end 0)))
