How to search whole buffer?

How to search whole buffer?

[Ulrich Scholz]

Hi, I'm using search-forward to search and replace strings.

(defun my-replace nil "change escape sequences to umlauts"
  (interactive)
   (while (search-forward "<DF>" nil t)
           (replace-match "ß" nil nil))
)

But that search does not search the whole buffer.  In particular, if I
perform two subsequent searches then the second does not find
anything.  So either I'm looking for something like
search-buffer (which I did not find yet) or for a method to set the
begin of the search to the first character of the current buffer.
(I've had a look at search but there was no documentation)

Thanks,

Ulrich

Hi Ulrich,

what you want is this:

--8<---------------cut here---------------start------------->8---
(defun my-replace ()
  "change escape sequences to umlauts"
  (interactive)
  (save-excursion
    (goto-char 1)
    (while (search-forward "ß" nil t)
      (replace-match "ß" nil nil))))
--8<---------------cut here---------------end--------------->8---

The `save-excursion' takes care that point is on the same position after
the replace and (goto-char 1) sets the point to the first position in
the buffer, so that the replace is done in the whole buffer.

HTH,

Ups, while testing I replaced the <DF> with ß. ;-)
