Instructions and scripts for setting Up IRSSI so that it does native Apple notifications.

readme.md

1. Place the ssh-config file in ~/.ssh/config
2. Place the irc-notify.sh file in ~/bin/irc_notify.sh
3. Place the fnotify.pl file on the remote server within ~/.irssi/scripts
4. Link the fnotify.pl script to ~/.irssi/scripts/autorun/fnotify.pl
5. Install terminal-notifier (link?)
6. SSH into the remote box: ssh personal -i .ssh/personal.pem (or whatever your keyfile is named).
7. From there, run a tmux session and then run irssi.

When you login to the remote box (where you'll be running irssi), the SSH config will tell SSH to first run the irc-notify.sh script, which will clear the fnotify file and, in effect, pipe the tail of the fnotify file to your local terminal-notifier program. (It will first kill any such commands that are already running.)

When you start up irssi on the remote server, it will, in turn, run the fnotify.pl script, which will check for highlighted messages in IRC (i.e. referencing your nick, or whatever you have set up for highlighting), and then write those lines to the fnotify file.

Since you now have a process piping that file to terminal-notifier on your local box, you'll get notifications any time a message is highlighted. If the pipe dies for some reason (typically, I suppose, because the SSH session that's tailing the fnotify file dies), you'll have to SSH in again, but you don't usually need to start another irssi session.
