I try to use alert and copy the example from here as below:

scratch buffer:

(require 'alert)

;; This is the most basic form usage
(alert "This is an alert")

;; You can adjust the severity for more important messages
(alert "This is an alert" :severity 'high)

;; Or decrease it for purely informative ones
(alert "This is an alert" :severity 'trivial)

;; Alerts can have optional titles.  Otherwise, the title is the
;; buffer-name of the (current-buffer) where the alert originated.
(alert "This is an alert" :title "My Alert")

;; Further, alerts can have categories.  This allows users to
;; selectively filter on them.
(alert "This is an alert" :title "My Alert" :category 'debug)

After eval-buffer, it seems nothing happens.

I am not sure what should I expect after evaluate the alert function?

  • Have you read the help page for alert (C-h f alert)? – Squidly Aug 13 '15 at 9:01
  • Isn't it almost the same as what I have posted? – Enze Chi Aug 13 '15 at 12:24

Maybe the messages are in the *Messages* buffer. You can go to it with C-x b *Messages* or simply with a left-click on the minibuffer.

    To examine *Messages*, you can also use C-h e. – xuchunyang Aug 13 '15 at 8:29
  • That messages are really in the *Message* buffer. But I can't see how dumping message to *Message* buffer can be called ALERT? Before I expect it is something like notification. – Enze Chi Aug 13 '15 at 12:27
