That is EXACTLY what I wanted! In the meantime, though, I
was able to hack together this:
(defun wake-up-saved-dired-buffer ()
"This function can be used to make a \"live\" dired buffer from
one saved to disk as an ordinary text file.
To try it out, open up dired in some buffer and save the buffer
as a the file my-dired-save.txt. Close the buffer and open it
again. You will now have a normal text file but with dired
contents. Now run this function.
I have not tested all types of dired commands but it seems to
work for the things I needed it for at the moment.
IMHO, this is kind of useful when you want to save large
listings that you have got from find-dired or find-grep-dired.
Maybe someone can merge this into all the different
session-saving packages out there?"
(interactive)
(goto-char (point-min))
;; Find the dir name
(if (not (search-forward-regexp " \\(.*\\):$"))
(error "This is no saved dired buffer")
(let ((dir (match-string 1))
(m1))
;; Enter dired-mode
(dired-mode dir)
;; dired needs the variable dired-subdir-alist
(set (make-local-variable 'dired-subdir-alist) nil)
(setq m1 (make-marker))
(set-marker m1 1)
(setq dired-subdir-alist (list (cons dir m1))))))
:)
