archiving mail with nnmail-expiry-target

archiving mail with nnmail-expiry-target

[martin.bishop]

In my .gnus I have the following

(setq nnmail-expiry-wait 'immediate)
(setq nnmail-expiry-target
        '(lambda (group)
         (concat "nnfolder:"
                 (format-time-string "%b-%Y." (current-time))
                 group)))


Is there any way to prevent gnus from opening the group to be archive
to in a buffer ?
I.E. when I go to exit emacs, I get prompted to save the Jun-2006.Inbox
buffer

Here you are using the nnfolder backend which is a single file based
group which gets loaded into a buffer. If you use nnml or some other
backend you'll get around this..

Are you sure you quit Gnus properly with 'q' in the Group buffer ?
Gnus should save the buffer at that time. You can also do it by
pressing 's' in the group buffer which saves all changes in the state
of groups etc.

I'll keep this in mind as a plan B. I was hoping to keep things in
separate mbox
files so that I can use various other tools against them.

Yes, I'm using q to exit gnus. I've just tried using s as well and this
also
doesn't save the changes. I still get prompted by emacs at quit time
to save Mail/Jun-2006/Inbox. Must gnus open an mbox file in a buffer to
append expired messages to it ? I'm starting to think that even if I
can
get it to save the changes, it is going to cause problems once I start
having up to a month worth of various mailing list mboxes open in
various
buffers. Is going to a different backend for expiry-targets the only
way to solve this ?

Barring any weird bug in Gnus, this leads me to think that Gnus is not
thinking of this folder as in it's active select methods...
And I think I know why. See how it is trying to place the archive
inside the Jun-2006 dir? This must be preventing Gnus from considering
that as a managed group. Try:

(setq nnmail-expiry-target
        '(lambda (group)
         (concat "nnfolder:"
                 (format-time-string "%b-%Y-" (current-time))
                 group)))

Notice that I replaced the '.' after the year with a dash.

Yes. That is how elisp handles updates to files.

They will only be opened if:
     a) You accessed them and did not exit the group
     b) Some messages were recently expired there.

If the change I suggest above does not do it, then it is the only one
_I_ see. Maybe someone more knowledgeable here can give a better suggestion.

Changes the location as predicted, but still needs to be saved manually
as before. I changed from nnfolder: to nnml: and things work properly
for both the dash and dot separation case. So, I'd suspect the expiry
routine in nnfolder.el is missing something. I've had a look, but my
lisp-fu is not strong enough yet.
