on [<modes>]input [<serial#>] [-|^]<match> { <action> }

This hook is triggered whenever a command is entered on the input line, or when text is sent to a channel or query.

This is a very powerful mechanism of the client. Used intelligently, it permits a very fine degree of control over the text entered on the input line. Used carelessly, and it can easily disable the client. Use with caution.

If a silent hook is set, one can use a loaded script to do preprocessing of the input line.

To emulate the INPUT_ALIASES setting:

 on ^input "*" {
    eval $*
 }
