gnus notifications setup

gnus notifications setup

[Noorul Islam K M]

I was desperately looking for something like this
http://julien.danjou.info/blog/2012/gnus-notifications.

I thought of setting this up but I could not make it work.

I tested this using the following expression and it works.

(gnus-notifications-notify "Noorul" "Testing notification" nil)

And I added the following line in .gnus.el

;;; Notification
(add-hook 'gnus-after-getting-new-news-hook 'gnus-notifications)

But when I press 'g' from groups buffer, I am not getting any
notifications even if I have new mails. Am I missing something?

From describe variable:

gnus-after-getting-new-news-hook is a variable defined in `gnus-start.el'.
Its value is (gnus-notifications gnus-display-time-event-handler)
Original value was 
(gnus-display-time-event-handler)

Thanks and Regards
Noorul

It sound like you haven't started up dbus. Put this in your ~/.profile:

   # DBus
   eval `dbus-launch`
   export DBUS_SESSION_BUS_ADDRESS

I think I have 

 noman in ~
$ --> echo $DBUS_SESSION_BUS_ADDRESS
unix:abstract=/tmp/dbus-uxvaB7e5OP,guid=044075e05c08bb0ac331d85900000027

OK, it is something else. Have you tried customizing
"gnus-notifications-minimum-level"? It defaults to Level 1 groups.

Also, I don't need to do:

,----
| ;;; Notification
| (add-hook 'gnus-after-getting-new-news-hook 'gnus-notifications)
`----

it works out of the box.

Cheers,
Charles

Oops, sorry about this part, I do have this in my gnus config
file. Sorry for the misinformation.

Ok, now I set this to 10 and it displays the notification. But my group
buffer is not displaying the unread count after pressing 'g'.

Also I get an error message 

gnus-string-match-p: Wrong type argument: stringp, nil

But when I try to debug this by setting debug-on-error to t, I get

Entering debugger...
button-at: Args out of range: 0

This is strange, I don't know `button-at' and it's not used in
gnus-notifications. Could you maybe try with a shorter/lighter Gnus
config, in case something else would trigger this?

It is trying to match a string with nil. I am not sure why the address
is nil in this case.

Debugger entered--entering a function:
  gnus-string-match-p("noorul@noorul\\.com" nil)
* gnus-notifications()
  run-hooks(gnus-after-getting-new-news-hook)
  apply(run-hooks gnus-after-getting-new-news-hook)
  gnus-run-hooks(gnus-after-getting-new-news-hook)
  gnus-group-get-new-news(nil)
  call-interactively(gnus-group-get-new-news nil nil)

Could you type `e' and then `address-components' so I see what the
address is?

And from code

(unless (gnus-string-match-p gnus-ignored-from-addresses
                                               address)

What if my gnus-ignored-from-addresses is nil?

You are right, I've added a check for both values.

It works now but pretty slow. I am not sure how this maximum level
setting will help to restrict some groups. I would like to have a
configurable custom variable groups list which should be ignored from
notifications. If you think this will be useful to others, I can come up
with a patch to add 'gnus-notifications-ignored-groups' variable.

Thanks and Regards
Noorul

The logic here is that you set the important groups that you want
notifications above and at the number set in
"gnus-notifications-minimum-level" by using group levels (set with S l
in the group buffer). For example, if you set it to "2", only groups
that are level 2 and 1 will have notifications.

I had missed this - I never had a reason to put my mail groups on level
1. Now I have.

Thanks for the tip!

Haha, same here. I never had a need to use group levels until now.

You're welcome.

If you want to check your D-Bus settings, and whether the notifications
daemon is running, you could apply

--8<---------------cut here---------------start------------->8---
(require 'notifications)
(notifications-notify :title "test")
--8<---------------cut here---------------end--------------->8---

Well, in my initial mail, I said;

I tested this using the following expression and it works.

(gnus-notifications-notify "Noorul" "Testing notification" nil)
