gnus-demon question

[Noorul Islam K M]

I have the following settings.

(gnus-demon-add-handler 'gnus-group-get-new-news 15 t)
(gnus-demon-init)

But still it looks like, emacs is not checking mails every 15 minutes
and also the *Group* buffer is not getting updated.

I use

No Gnus v0.11
GNU Emacs 24.0.50.1 (i686-pc-linux-gnu, GTK+ Version 2.12.12)
 of 2010-11-26 on noorul

Everything works fine with Gnus

I hope someone else might also be facing similar problem. Anyone?

Thanks and Regards
Noorul

The `gnus-demon-init' is not needed.  `gnus-demon-add-handler' calls it
already.  Your code 1) adds a new handler, 2) kills all old handlers and
initializes them anew (gnus-demon-init), and then does 2) again.

Looking at the docs

,----[ (info "(gnus)Daemons") ]
|    If IDLE is `t', then the function will be called after TIME minutes
| only if Emacs is idle.  So if Emacs is never idle, the function will
| never be called.  But once Emacs goes idle, the function will be called
| every TIME minutes.
`----

Hm, reading that statement, I'd say that your code would check every 15
minutes if emacs is idle, and if so, call `gnus-group-get-new-news'.

But looking at the code

  (gnus-demon-add-handler 'gnus-group-get-new-news 15 t)

is equivalent to

  (gnus-demon-add-handler 'gnus-group-get-new-news 15 15)

,----[ (info "(gnus)Daemons") ]
|    If IDLE is a number and TIME is a number, the function will be
| called every TIME minutes only when Emacs has been idle for IDLE
| minutes.
`----

So your code will call `gnus-group-get-new-news' every 15 minutes after
emacs has been idle for at least 15 minutes.  That's pretty seldomly, I
guess...

So what's wrong?  Code, documentation, or my understanding of the code?

The same setup was working when I was using Gnus. I use emacs as I was
using earlier. So the idleness remains the same. There are days when I
lock the system for several hours. Still there is no effect.

I've never used that, and I'm not sure whether that's supposed to work
or not.  Anybody?

How do we make gnus to check mails at regular intervals? If there is any
other way then it will be great to know.

I use this in my ~/.gnus:

  ; Daemon to fetch email every 5 minutes when Emacs has been idle for 5 minutes:
  (gnus-demon-add-handler 'gnus-demon-scan-mail 5 5)
  (gnus-demon-init)

Works like a charm (note that I don't think this updates the *Group*
buffer; I am not 100% sure though).

Then how do you know that new mails arrived?

I go 'g'.

(And I realize that probably isn't what you want; my setup isn't that
vanilla - among other things I forward emails to my phone when email is
fetched by the demon, but not when fetched by (my) hand.)

Hopefully someone else can either tell us that I am wrong about the
*Group* or tell us how to have it update :-)

I do:

(gnus-demon-add-handler 'gnus-group-get-new-news 5 3)

which updates the *Group* buffer fine (plus I don't bother with
gnus-demon-init)

So basically gnus-demon-scan-news without the wrapping?

I think I use gnus-demon-scan-mail because I don't need the news-servers
to be bothered when I am not at the Emacs. It would be nice the the
*Group* buffer was updated though.

I should test to see if it is just my imagination, or it really isn't
updated...

That isn't necessary?

It really isn't. I will try the scan-news version and see if that isn't
more fun.

Thanks for the nudge!

No, `gnus-demon-add-handler' calls it for you.  Calling it explicitly
again will cancel all timers and initialize them anew for a second
time. :-)

I wonder why I have it in my configuration then. Oh well... Maybe it was
to have delayed mail sent, from before I used the demon to look for new
mail? Probably I am just making things up by now.

Re: gnus-demon question

[Philipp Haselwarter]

The problem I encountered with the demon is that `gnus-demon-init'
(which gets called at the end of `gnus-demon-add-handler' btw) has to be
called at a certain point of time (after gnus is launched?).
As I split up my gnus config to have only personal information in my
.gnus.el and keep the other stuff, like adding the handlers, elsewhere,
I used (eval-after-load "gnus" 'load-my-gnus-config) which apparently
resulted in `gnus-demon-init' being run at some suboptimal time.

Long story short, this reliably made the demon work for me:

--8<---------------cut here---------------start------------->8---
(add-hook 'gnus-started-hook 'gnus-demon-init)
--8<---------------cut here---------------end--------------->8---

Also, I use different handlers to get news by group-level; I poll my
imap server way more often than gmane. I can post the setup if anyone's
interested.

I use this (first param is TIME, second is IDLE)

  (gnus-demon-add-handler 'gnus-demon-scan-news 15 5)

The docs say

,----[ (info "(gnus)Daemons") ]
|    If IDLE is a number and TIME is a number, the function will be

| minutes.
`----

so I'd expect it to run every 15 minutes but only if emacs has been idle
for 5 minutes.

Nevertheless, that doesn't match my observations.  It seems, that the
docs are correct for the first run, but any subsequent run doesn't check
if emacs has been idle.  Often, I'm writing in emacs, do a 15 seconds
thinking pause, and then I can see Gnus checking for new mail/news.

Well, because that's so fast nowadays, it's not a big issue for me.  But
the docs don't seem to be correct...
