on QUIT

The on QUIT event triggers when a user quits IRC while on the same channel as you.


Format: on <level>:QUIT:<commands>
Example: on 1:QUIT:/notice $me $nick just quit IRC with the message $1-

Examples

on 1:QUIT:/ame waves bye-bye to $nick *sniff*

This triggers when a user quits IRC while on the same channel as you. The $1- parameters hold the user's quit message.
