I came up with
--8<---------------cut here---------------start------------->8---
(defun test_gen (begin end from to)
(save-excursion
(save-restriction
(let (deactivate-mark)
(narrow-to-region begin end)
(goto-char (point-min))
(while (re-search-forward from end t)
(replace-match-maybe-edit to t nil nil (match-data) nil)))
)))
--8<---------------cut here---------------end--------------->8---
I used replace-match-maybe-edit because I wanted to be prompted for each
replacement, and replace-match wouldn't allow it. However with
replace-match-maybe-edit, the excursion is messed up at the end. It
wasn't the case with replace-match.
