I use ERC for all my IRC chatting. I finally got fed up with not noticing someones message because I didn't have emacs focused. So I spent my evening concocting a more noticeable messaging system through Pymacs and libnotify.
Half way though implementing this, wouldn't you know it, I found ErcPageMe which does exactly what I wanted. I figured I was learning quite a bit and I continued writing my own version. I expanded on their code and (at least for me) made some improvements. So kudos go to whoever wrote ErcPageMe :)
The following code will pop up a message on your gnome desktop alerting you whenever you receive a personal message or when someone mentions your nickname in a channel. It also avoids notification for the same user in the same channel if they triggered a message within the last 30 seconds.
Here is my lisp and embedded python/pymacs code:
(defun notify-desktop (title message &optional duration &optional icon) "Pop up a message on the desktop with an optional duration (forever otherwise)" (pymacs-exec "import pynotify") (pymacs-exec "pynotify.init('Emacs')") (if icon (pymacs-exec (format "msg = pynotify.Notification('%s','%s','%s')" title message icon)) (pymacs-exec (format "msg = pynotify.Notification('%s','%s')" title message)) ) (if duration (pymacs-exec (format "msg.set_timeout(%s)" duration)) ) (pymacs-exec "msg.show()") ) ;; Notify me when someone wants to talk to me. ;; Heavily based off of ErcPageMe on emacswiki.org, with some improvements. ;; I wanted to learn and I used my own notification system with pymacs ;; Delay is on a per user, per channel basis now. (defvar erc-page-nick-alist nil "Alist of 'nickname|target' and last time they triggered a notification" ) (defun erc-notify-allowed (nick target &optional delay) "Return true if a certain nick has waited long enough to notify" (unless delay (setq delay 30)) (let ((cur-time (time-to-seconds (current-time))) (cur-assoc (assoc (format "%s|%s" nick target) erc-page-nick-alist)) (last-time)) (if cur-assoc (progn (setq last-time (cdr cur-assoc)) (setcdr cur-assoc cur-time) (> (abs (- cur-time last-time)) delay)) (push (cons (format "%s|%s" nick target) cur-time) erc-page-nick-alist) t) ) ) (defun erc-notify-PRIVMSG (proc parsed) (let ((nick (car (erc-parse-user (erc-response.sender parsed)))) (target (car (erc-response.command-args parsed))) (msg (erc-response.contents parsed))) ;;Handle true private/direct messages (non channel) (when (and (not (erc-is-message-ctcp-and-not-action-p msg)) (erc-current-nick-p target) (erc-notify-allowed nick target) ) ;Do actual notification (ding) (notify-desktop (format "%s - %s" nick (format-time-string "%b %d %I:%M %p")) msg 0 "gnome-emacs") ) ;;Handle channel messages when my nick is mentioned (when (and (not (erc-is-message-ctcp-and-not-action-p msg)) (string-match (erc-current-nick) msg) (erc-notify-allowed nick target) ) ;Do actual notification (ding) (notify-desktop (format "%s - %s" target (format-time-string "%b %d %I:%M %p")) (format "%s: %s" nick msg) 0 "gnome-emacs") ) ) ) (add-hook 'erc-server-PRIVMSG-functions 'erc-notify-PRIVMSG)
