Message-ID: <4DBBCEE7.8030000@easy-emacs.de> (raw)
Hi,
occassionally want to compare a file with its auto-saved version.
Couldn't find a function doing this.
Tweaked diff-backup for the purpose.
The result:
(defun diff-autosaved (&optional switches)
"Diff this file with its auto-saved version or vice versa.
With prefix arg, prompt for diff switches."
(interactive (list (diff-switches)))
(let ((dir default-directory)
(file (file-name-nondirectory (replace-regexp-in-string "#" ""
(buffer-file-name))))
bak ori)
(if (string-match "^#" file)
(setq bak file
ori (replace-regexp-in-string "#" "" file))
(setq bak (concat "#" file "#")
ori file))
(setq bak (concat dir bak))
(setq ori (concat dir ori))
(diff bak ori switches)))
Comments welcome.
Andreas
