Hi, someone on IRC asked about how to make a function that delays sending of email, so as to have a chance to edit/cancel within 2 minutes or so. I came up with
(defun message-wait-send-and-exit (&optional arg)
"Bury the buffer and wait a bit, then send message like
`message-send-and-exit'."
(interactive "P")
(let ((timeout "2 minutes")
(buf (current-buffer)))
(message "Sending %s in %s" buf timeout)
(bury-buffer)
(run-at-time timeout
nil
(lambda (arg buf)
(when (buffer-live-p buf)
(with-current-buffer buf
(let ((inhibit-quit nil)) ; avoid hang if e.g. server is
slow/down
; though this makes C-g
dangerous
(message-send-and-exit arg)))))
arg
buf)))
but I know it's fraught with problems (missing headers cause
interactive questions to pop up out of nowhere, a C-g at the wrong
moment will cancel sending).
Has anyone attempted something like this before? I guess to avoid the
problem of interactive questions you'd have to write your own version of
`message-send' and do the `run-at-time' there. Perhaps `with-timeout'
could be used along with inhibit-quit to avoid stray C-g's while still
not hanging on server trouble? (Or is this a much bigger project than
that?)
