New mail indicator

New mail indicator

[Roman Belenov]

Hello,

Is there an easy way to add some indicator (like some text in the
modeline of all buffers) when there is new unread mail in GNUS ?

And what should I expect to see in the modeline ? At this moment I
have about 100 unread messages in GNUS but I can't find any indication.

This tells you whether you have mail in /var/mail/jrl.  It does not
tell you about the number of unread messages in Gnus.

So it's not related to my question (I don't have /var/... at all under
Windows NT). Is there a way to indicate that there are unread messages
in Gnus ?

In ~/News, there Gnus put them (they were received via POP3).

Well, I think there is no predefined functionality in Gnus for doing
this, but try M-: (gnus-group-unread "nnml:mail.misc") RET -- does
that return a useful value?  (You might wish to substitute another
group name rather than nnml:mail.misc.)  And then, there is M-:
(gnus-topic-unread "Gnus") RET which returns the number of unread
messages in that topic.

But I think it does not make sense to show the number of unread
messages in Gnus, except maybe if you're using the demon.  Are you a
demonic Gnus user?

Normally, I think it would make more sense to have a program which
contacts the POP server every now and then to determine the number of
messages waiting there.  Or maybe the IMAP server.  Maybe the nice
package epop3mail.el from Franklin Lee provides that functionality for
POP?  Dunno about IMAP.

Sorry, of course they are in ~/Mail (although it doesn't matter).

Thanks, these functions should suffice.

Yes. Actually, I've just started using Gnus as my mail reader; but my
previous reader checked POP3 mailbox (getting new mail) once a while
so I enabled similar functionality in Gnus.

Well, maybe just polling POP3 server will be more useful - I'll try it too.

Well, in group buffer, I can usually see how many unread messages are
in each topics(?) like this:

       5: fj.editor.emacs                          000107
       2: fj.editor.xemacs                         000107
      12: fj.os.linux                              000107
      36: nnml:ML.gnus                             000107
       8: nnml:ML.i386                             000107
       1: nnml:ML.mac68k                           000107
       4: nnml:ML.macML                            000107
       1: nnml:ML.yokohama                         000106
       1: nnml:MM.Mag2                             991231
       1: nnml:MM.WebCatch                         000107
       1: nnml:MM.meeting                          991229

# note: I'm a user of *NetBSD/mac68k* and get mails from pop server
        using *fetchpop* (=mail retrieving programs). And in group
        buffer, I type *g* so that I can get mails from
        /var/mail/shigeki and split mails.

Isn't that what you wanna do ?

Now, I wanted to see if new mail have arrived without switching to
Gnus (I use Gnus daemon to get new mail).

BTW I altered my mode line to show the number of unread messages (if
there are any), but encountered the following problem: is there a hook
that is called *after* the article was marked as read. I defined a
function that changes the modeline and call it after the new mail was
obtained (via gnus-after-getting-new-news-hook), but it also should be
called when articles are marked as read so what mode line will always
present correct number of unread articles; I tried some hooks like
gnus-mark-article-hook without success. Are there any suitable hooks
for this ?

Also I found that functions mentioned by Kai (gnus-topic-unread etc.)
are not even mentioned in the texinfo documentation, although they are
quite useful.

Roman,

Is it possible to modify the demon to update the modeline?  i.e. I
have the following running under the gnus-use-demon...

(defun gnus-demon-scan-mail-groups1 ()
  (save-window-excursion
    (when (gnus-alive-p)
      (save-excursion
        (set-buffer gnus-group-buffer)
        (gnus-group-get-new-news 1)))))

Is there a way to count how many messages are in the group-1 groups
and then change the modeline?  It would't update the modeline directly
after your ead your messages, but it would next time you ran the
demon.

Let us know what you come up with - this would be a fun thing to have,

Cheers,  Jody

Hi, people.  I'm not sure if this addresses your question, but there is
a mechanism in Gnus to force the display of `%' in the Group buffer next
to all groups which received messages and which you did not visit yet.

Building on this, I customized the Topics mode to force the display of
normally hidden groups, as long as they have that `%' mark.  I also added
the `%' command, both in the Group buffer and in the Summary buffer, that
automatically selects and visits the next group which has such a `%' mark
(and also gets new mail before doing so, if any arrived in the meantime).

These things make Gnus, as a mail reader, significantly more useful for
me, especially I also managed to sort most summaries with more recent
articles first.  I have many groups, many of which are hidden, and mail
gets split a bit everywhere when received.  I like to (at least try to)
browse all incoming mail once, not too long after its receipt.

P.S. - I thought I posted all this code here (but maybe a while ago...).
Or maybe I sent it to Lars only?  It might be.  In any case, Lars told me
that he wants to revisit, rethink and refresh this area of Gnus.

Could this be adapted such that Gnus always shows groups which have
cached articles?  I'd be very interested in that.  (A solution
requiring topic mode to be on is okay.)

I've added the following to my .gnus to add the number of unread
messages to the modeline (all my mail groups are under "Mail" topic):

(setq my-gnus-unread-mail-articles-p nil)
(setq my-gnus-unread-mail-articles "0")

(defun my-update-gnus-mode-line ()
  (let ((unread-articles (gnus-topic-unread "Mail")))
    (setq my-gnus-unread-mail-articles-p (> unread-articles 0))
    (setq my-gnus-unread-mail-articles (format "%d" unread-articles))
    (force-mode-line-update)))

(add-hook 'gnus-after-getting-new-news-hook 'my-update-gnus-mode-line)

(or (boundp 'my-gnus-mode-line-activated)
    (progn
      (setq my-gnus-mode-line-format
            '(my-gnus-unread-mail-articles-p ("Unread: " my-gnus-unread-mail-articles "  ")))
      (setq global-mode-string (cons my-gnus-mode-line-format global-mode-string))))

(setq my-gnus-mode-line-activated t)


Note that the modeline is not changed then articles are read since I
couldn't find suitable hook.
