Thank you so much Javier for the detailed explanation, it works beautifully now!

The only problem is that if I miss a message, I may have to press "C-t m" repeatedly to "search" for previous messages. Is there a way to show all the messages, similar to Emacs's *Messages* buffer?

You can use :: to access internal symbols of a package. So the code in my previous email should be amended to 

(load-module "notify")


(load-module "notify")

Long version:
# is a non-terminating dispatching macro character, which means that the meaning is determined by the character following the sharp-sign (#). #: creates an is an uninterned symbol, that is a symbol that doesn't belong to a package. They are normally used for package designators among other things. In the case of  (in-package #:notify), #:notify stands in (denotes) the package notify. #' is short hand notation for accessing the function namespace. Because funcall takes a function designator we can get away with passing it a symbol and it will be coerced it to the function bound to that symbol in the function namespace.

Hope that clears things up

Thank you very much for your detailed instruction Javier!

I'm very confused by the package name "#:notify". What does the "#" prefix mean? I can only call the functions inside this package by:

  (in-package #:notify)

But I don't want to introduce a namespace only to call one or two functions. I want to be able to call the function with namespace prefix like:


But this doesn't work. What did I do wrong?

Upon reading the I've realized the instructions could be written in a
more straightforward manner. All you have to do for the contrib to work is put
the following lines in your rc file.

(load-module "notify")
(notify-server-on) ; or (notify-server-toggle)

With that in your rc file show-notification would run every time a slack
notification, or any other notification, is sent. In the case of
show-notification that means using the message box that StumpWM for its

If you would like that the notification be displayed in a different manner you
would have to change the function stored in *notification-received-hook* (which
incidentally is not a hook, hooks are lists of functions). For example Ubuntu
comes with libnotify which you can use from the CLI through notify-send. One
could use libnotify by placing the following code it its rc-file after loading
the notify module.

(defun libnotify-show-notification (app icon summary body)
   (format nil "notify-send --app-name=~A --icon=~A \"~A\" \"~A\""
           body)) )
(setf notify:*notification-received-hook* #'libnotify-show-notification)

I still have no idea how to get "notify" working. Would it be possible for someone to provide me a bit more instruction as to how to get Slack notifications in StumpWM? The following is my ./stumpwm.d/init.lisp:

;; -*-lisp-*-

(in-package :stumpwm)

;; Bind "c" to gnome-terminal instead of xterm
(define-key *root-map* (kbd "c") "exec gnome-terminal")

(setf *mode-line-position* :bottom)

Thank you very much Javier. Because I'm new to Common Lisp, it would be a lot easier for me if I could have some usage information with examples for this "notify" package. Could you point me to some of these information as I didn't find them on the GitHub link.

Have a great day,

Hi list,

I'm using Linux Mint 17.3 at home, and 18.3 at work. I'm trying to use StumpWM. However, since we use Slack at work, I have to be able to get notified whenever new slack messages arrive. Without this ability, StumpWM would be useless for me. I've tried to run `gnome-panel' but all I got was a black band at the top of the screen showing nothing. Is it possible to have this notification in mode line?

Thanks in advance,
