In summary mode, when I press R for gnus-summary-reply-with-original or F for gnus-summary-followup-with-original, my signature gets inserted below the original message text.
How can I tell gnus to insert my signature at the very top of the message, before the quoted text of the original?
It looks as though that's not an option built into Gnus (as of v5.10.8), so you have to redefine one of the built-in functions like so:
(eval-after-load "gnus-msg"
(defun gnus-inews-yank-articles (articles)
(let (beg article yank-string)
(goto-char (point-max)) ; put articles after signature
(insert "\n") ; and one extra newline
; was this (message-goto-body)
(while (setq article (pop articles))
(when (listp article)
(setq yank-string (nth 1 article)
article (nth 0 article)))
(save-window-excursion
(set-buffer gnus-summary-buffer)
(gnus-summary-select-article nil nil nil article)
(gnus-summary-remove-process-mark article))
(gnus-copy-article-buffer nil yank-string)
(let ((message-reply-buffer gnus-article-copy)
(message-reply-headers
;; The headers are decoded.
(with-current-buffer gnus-article-copy
(save-restriction
(nnheader-narrow-to-headers)
(nnheader-parse-naked-head)))))
(message-yank-original)
(setq beg (or beg (mark t))))
(when articles
(insert "\n")))
(push-mark)
(goto-char beg))))
I wrapped the new definition of 'gnus-inews-yank-articles in an eval-after-load form so that it gets defined at the appropriate time. Obviously, if you want to allow customization, create a variable and write the appropriate if statement.
Nice. By the way, don't forget to quote the eval-after-load form (else error occurs):
(eval-after-load "gnus-msg" '(defun gnus-inews-yank-articles (articles) ...))
