# tmux_away irssi module
#
# Written by Colin Didier <cdidier@cybione.org> and heavily based on
# screen_away irssi module version 0.9.7.1 written by Andreas 'ads' Scherbaum
# <ads@ufp.de>.
#
# Updated by John C. Vernaleo <john@netpurgatory.com> to handle tmux with
# named sessions and other code cleanup and forked as version 2.0.
#
# usage:
#
# put this script into your autorun directory and/or load it with
# /SCRIPT LOAD <name>
#
# there are 5 settings available:
#
# /set tmux_away_active ON/OFF/TOGGLE
# /set tmux_away_repeat <integer>
# /set tmux_away_grace <integer>
# /set tmux_away_message <string>
# /set tmux_away_window <string>
# /set tmux_away_nick <string>
#
# active means that you will be only set away/unaway, if this
# flag is set, default is ON
# repeat is the number of seconds, after the script will check the
# tmux session status again, default is 5 seconds
# grace is the number of seconds, to wait additionally, before
# setting you away, default is disabled (0)
# message is the away message sent to the server, default: not here ...
# window is a window number or name, if set, the script will switch
# to this window, if it sets you away, default is '1'
# nick is the new nick, if the script goes away
# will only be used it not empty
# variables
