Thanks, Adam and Reiner, I should've guessed it was solved already :)
I prefer a shorter demon timeout for this purpose, but I don't need the
full news scan, so I used
(gnus-demon-add-handler 'gnus-delay-send-queue 1 nil) ; call every other
minute regardless of idleness
(gnus-demon-init)
And for the actual sending, in case anyone's interested:
(defvar message-delayed-send-default-minutes 2
"Default delay in minutes before delayed-sending with
`message-delayed-send-and-exit'")
(defun message-delayed-send-and-exit ()
"Use `gnus-delay-article' to send after
`message-delayed-send-default-minutes' minutes."
(interactive)
(message "Sending in %s minutes" message-delayed-send-default-minutes)
(gnus-delay-article (format "%sm" message-delayed-send-default-minutes)))
(define-key message-mode-map (kbd "C-c C-c") 'message-delayed-send-and-exit)
And in case I exit gnus before it's sent, I added:
(defun gnus-delay-send-queue-hurry ()
"As `gnus-delay-send-queue, but also send anything that is to
be sent within `message-delayed-send-default-minutes minutes."
(interactive)
(save-excursion
(let* ((group (format "nndraft:%s" gnus-delay-group))
(message-send-hook (copy-sequence message-send-hook))
articles
article deadline)
(when (gnus-group-entry group)
(gnus-activate-group group)
(add-hook 'message-send-hook
(lambda () (message-remove-header gnus-delay-header)))
(setq articles (nndraft-articles))
(while (setq article (pop articles))
(gnus-request-head article group)
(set-buffer nntp-server-buffer)
(goto-char (point-min))
(if (re-search-forward
(concat "^" (regexp-quote gnus-delay-header) ":\\s-+")
nil t)
(progn
(setq deadline (nnheader-header-value))
(setq deadline (apply 'encode-time
(parse-time-string deadline)))
;; The difference:
(setq deadline (time-subtract
deadline
(seconds-to-time
(* 60 message-delayed-send-default-minutes))))
(setq deadline (time-since deadline))
(when (and (>= (nth 0 deadline) 0)
(>= (nth 1 deadline) 0))
(message "Sending delayed article %d" article)
(gnus-draft-send article group)
(message "Sending delayed article %d...done" article)))
(message "Delay header missing for article %d" article)))))))
(add-hook 'gnus-exit-gnus-hook 'gnus-delay-send-queue-hurry)
(I guess another possibility would be to first go through nndraft and
alter the header, then call `gnus-delay-send-queue', but most of that
function consists of finding delayed articles anyway …)
