# based on the nicklist.pl script
################################################################################
# tmux_nicklist.pl
# This script integrates tmux and irssi to display a list of nicks in a
# vertical right pane with 20% width. Right now theres no configuration
# or setup, simply initialize the script with irssi and by default you
# will get the nicklist for every channel(customize by altering
# the regex in /set nicklist_channel_re)
#
# /set nicklist_channel_re <regex>
# * only show on channels matching this regular expression
#
# /set nicklist_max_users <num>
# * only show when the channel has so many users or less (0 = always)
#
# /set nicklist_smallest_main <num>
# * only show when main window is larger than this (0 = always)
#
# /set nicklist_pane_width <num>
# * width of the nicklist pane
#
# /set nicklist_color <ON|OFF>
# * colourise the nicks in the nicklist (required nickcolor script
# with get_nick_color2 and debug_ansicolour functions)
#
# /set nicklist_gone_sort <ON|OFF>
# * sort away people below
#
# It supports mouse scrolling and the following keys:
# k/up arrow: up one line
# j/down arrow: down one line
# u/pageup: up 50% lines
# d/pagedown: down 50% lines
# gg: go to top
# G: go to bottom
#
# For better integration, unrecognized sequences will be sent to irssi and
# its pane will be focused.
#
# to toggle the nicklist if it is in the way you can make a key binding:
# /bind meta-Z /script exec Irssi::Script::tmux_nicklist_portable::toggle_nicklist
