Have come up with the following function. Would this be enough to count the
number
oy opening parantheses in a region ?
(defun bracketing-count (region-start region-end)
"Counts opening and closing bracketing marks.
Interactive functions enable them to be called using `M-x`"
(interactive "r") ; gets region start and end
(message "Counting bracketing marks ...")
(save-excursion
(let (count)
(setq count 0)
(goto-char region-start)
(while (and (< (point) region-end)
(search-forward "\(" region-end t))
(setq count (1+ count))) ))))
