On open

The on OPEN events trigger for various events relating to the opening of a window.

on <level>:OPEN:<?|@|=|!|*>:<matchtext>:<commands>

The matchtext can be a wildcard match or even a regular expression. To use regular expressions as matchtext, you need the $-Prefix.

Read access levels to get more info about the <level> field.

The location where this event occurrs can be either a channel (#), a query (?), a DCC-window (=) or a fileserver-window (!) or everything (*).

Note that in the case of dcc sessions, it is trigger when a dcc connection has opened.

Example

on *:Open:?:*: {
 echo -a $nick has just opened a query window with you!
}

This example reacts on every opening query and echos it to the active window.

on ^*:Open:?:*: {
 if ($nick == idiot) {
  halt
 }
}

This example also reacts on every opening query but before the window has opened, checks if the nick is idiot and if it is, halts the opening.
