Hello Docdiff is a nice utility which allows to compare 2 files word by word and writes the difference in one single HTML file, in which the differences are highlighted. The result looks very much as if a human would have corrected some text. Now I wrote a primitive function which works for two files but I would like to modify ediff-revision (using RCS) such that docdiff runs on two versions of a file under version control. Here is what I did and what does not work: (defun docdiff-vc-version () "Invoke docdiff for the current buffer, and run mozilla-firefox -remote openfile(filename) to preview the diff" (interactive) (let* ((currentname (buffer-file-name (current-buffer))) (newbuffer (vc-version-other-window (read-string "Version number: "))) (origname (vc-version-other-window (read-string "Version number: ")))) (diff-command "/usr/bin/docdiff --html %s %s > %s") (mozilla-command-line "/usr/local/seamonkey/seamonkey -remote 'openfile(%s)'") (moztmpfile-name (concat default-directory ".docdiff/docdifftmp.html"))) (shell-command (format diff-command origname newbuffer moztmpfile-name)) (shell-command (format mozilla-command-line moztmpfile-name))) The problem is the second call: (vc-version-other-window (read-string "Version number: ")))) in the first call xemacs has identified the other version say, test.~1.1~ but then in the second call applies it to that file (and fails since this file is _not_ under version control) and not the original file which _is_ under version control. I tried several tricks such that the second vc-version-other-window call takes place in the original buffer but I did not succeed it also would help if vc-version-other-window would allow me to specify the file but it does not. If somebody has an idea I would be grateful.
