;;; Commentary:

;; Functions to studlycapsify a region, word, or buffer.  Possibly the
;; esoteric significance of studlycapsification escapes you; that is,
;; you suffer from autostudlycapsifibogotification.  Too bad.

;;; Code:

(defun studlify-region (begin end)
  "Studlify-case the region"
  (interactive "*r")
      (goto-char begin)
      (while (re-search-forward "\\w+" end t)
	(let ((rnd (loop for pos from (match-beginning 0) to (match-end 0)
		     sum (or (char-after pos) 0))))
	  (loop for pos from (match-beginning 0) to (1- (match-end 0)) do
	    (let ((c (char-after pos)))
	      (when (= (% (+ c rnd) 4) 2)
		(if (eq c (upcase c))
		    (downcase-region pos (1+ pos))
		  (upcase-region pos (1+ pos)))
		(incf pos)))))))))

(defun studlify-word (count)
  "Studlify-case the current word, or COUNT words if given an argument"
  (interactive "*p")
  (let ((begin (point)) end rb re)
    (forward-word count)
    (setq end (point))
    (setq rb (min begin end) re (max begin end))
    (studlify-region rb re)))

(defun studlify-buffer ()
  "Studlify-case the current buffer"
  (interactive "*")
  (studlify-region (point-min) (point-max)))
