# Select a buffer from dmenu or rofi
# To call externally (IE: from i3), enable weechat fifo and run:

#
# Optionally requires i3-py [py2] (or i3ipc [py3]) to focus weechat in i3
#
# History:
# 2017-05-03, Ferus
# version 0.1.1: fix argument error for config_set_plugin
# 2016-05-01, Ferus
# version 0.1: initial release - requires WeeChat ≥ 0.3.7
# TODO:
# Option to remove certain buffer types
# Implement `focus` for other window managers
# if buffer == currentbuffer: switch to previous buffer
