I noticed that Wanderlust 2.15.9 (Almost Unreal) does not automatically mark an email as "answered" to which I have written a reply, as some other mail clients do. How can I make it do so? I am aware that there are wl-summary-mark-as-answered and the likes, but I am not sure how to use them from a elisp code.

  • I use wl-summary-reply-with-citation and mine gets marked as "a" with the whole line is wl-highlight-summary-answered-face, but I don't know if I previously fixed it to mark the email as answered (it has been several years already). What function are you using to answer? I'm happy to trace, but would like to make sure I'm starting with the right function.

  • @lawlist Thank you for your attention! I use mime-preview-follow-current-entity in an MIME-View-mode buffer, since oftentimes I want to cite only the text/plain part of the email. And you are right, if I use your function the message gets marked as answered.

  • Rather than getting fancy with advice, I would probably just create a new function: (defun foo () (interactive) (wl-summary-mark-as-answered) (mime-preview-follow-currentity)) I looked at the function you are calling and I didn't see any hooks that were obvious.

  • @lawlist Thank you for your help. Ideally, I'd like to mark the message as answered only after sending the reply, since I often start writing a reply without completing it...

  • What function do you use to send the email after replying with mime-preview-follow-current-entity?

The following answer is based on a bare-bones default configuration, with the following three steps:

  1. From the Summary buffer, select a message with the space bar (aka wl-summary-read).

  2. From the " *WL:Message*" buffer, type M-x mime-preview-follow-current-entity.

  3. From the "+draft/1" buffer, press C-c C-c (aka wl-draft-send-and-exit).

CAVEAT:  The default value for mime-preview-following-method-alist is ((wl-original-message-mode . wl-message-follow-current-entity)).

(require 'wl)

(defun wl-message-follow-current-entity (buffer)
  "Follow to current message.  @lawlist redefined this function so that
`wl-draft-reply' uses the optional argument of NUMBER.  NUMBER will become
`wl-draft-parent-number' by virtue of `wl-draft-create-buffer'."
  (wl-draft-reply  ;; reply to all
  (let ((mail-reply-buffer buffer))
    (wl-draft-yank-from-mail-reply-buffer nil)))
  • I put your code in my .wl, but it didn't mark the message as answered. Perhaps this has to do with lexical/dynamic binding? (My Emacs version is 24.4.1.)

  • In the comments underneath the original question, you indicated that the buffer is in mime-view-mode. The default configuration when following steps 1, 2 and 3 above will result in a wl-draft-mode buffer. So, we need to backtrack to see what actual steps are you taking beginning from the Summary buffer to end up with a mime-view-mode buffer after launching M-x mime-preview-follow-current-entity. We should also check the value of mime-preview-following-method-alist to see whether you have modified the default setting ((wl-original-message-mode . wl-message-follow-current-entity))

  • As it turns out, your code works now. I believe what I was experiencing was due to some inconsistency in defuns or lack of synchronization between Wanderlust and the IMAP server. Thank you!

    I was able to simply everything down to just adding an optional argument to wl-draft-reply within wl-message-follow-current-entity. The previous fix to wl-draft-send relating to using the mail-send-actions is a bonafide fix, but is not needed for this answer.
