Use `notifications-notify`, not `notify-send` command?

[egh]

Since emacs 24.1 (at least?), emacs supports alerting via dbus directly, rather than using notify-send. It would, I believe, be easy to replace or enhance the libnotify alerts to use notifications.el directly, rather than using notify-send.

I am happy to implement this. Is there a reason to retain the old use of notify-send, though? For instance to support emacs older than 24.1?

e.g.

(defun alert-libnotify-notify (info)
  "Send INFO using notifications-notify.
Handles :ICON, :CATEGORY, :SEVERITY, :PERSISTENT, :NEVER-PERSIST, :TITLE
and :MESSAGE keywords from the INFO plist.  :CATEGORY can be
passed as a single symbol, a string or a list of symbols or
strings."
  (if (fboundp #'notifications-notify)
      (let ((category (plist-get info :category))
            (urgency (cdr (assq (plist-get info :severity) alert-libnotify-priorities))))
        (notifications-notify
         :title (alert-encode-string (plist-get info :title))
         :body (alert-encode-string (plist-get info :message))
         :app-icon (or (plist-get info :icon) alert-default-icon)
         :category (cond ((symbolp category)
                          (symbol-name category))
                         ((stringp category) category)
                         ((listp category)
                          (mapconcat (if (symbolp (car category))
                                         #'symbol-name
                                       #'identity)
                                     category ",")))
         :timeout (* 1000 ; notify-send takes msecs
                     (if (and (plist-get info :persistent)
                              (not (plist-get info :never-persist)))
                         0 ; 0 indicates persistence
                       alert-fade-time))
         :urgency (if urgency (symbol-name urgency) "normal")))
    (alert-message-notify info)))
