That is useful. I am launching software through Emacs and often those
programs should persist.
It would be good to have some prefix or similar command to make it
persist.
As a side note, not quite relate, but could be, some software I cannot
launch with M-! but it works with M-& -- example is rox and retext. It
is very unclear why is this happening, do you maybe know a reason?
For example this below does not work with `retext' editor neither M-!
retext works, but M-& retext does work.
(defun rcd-edit-with-external-editor ()
(interactive)
(let* ((buffer (current-buffer))
(text (buffer-substring-no-properties (point-min) (point-max)))
(mode major-mode)
(file (concat (or (getenv "TMPDIR") "/tmp/") "temp-file")))
(string-to-file-force text file)
(shell-command (format "retext %s" file))
(erase-buffer)
(insert (file-to-string file))
(goto-char 0)))
If I use other GUI editor it does work.
