# 2013-06-27: nils_2, (freenode.#weechat)
#       0.3 : fix: bug with root bar
#
# 2013-01-25: nils_2, (freenode.#weechat)
#       0.2 : make script compatible with Python 3.x
#
# 2012-12-23: nils_2, (freenode.#weechat)
#       0.1 : initial release
#
# requires: WeeChat version 0.3.0
#
# How to use:
# ===========
#
# Template:
#  /set plugins.var.python.text_item.<item_name> <type> <${color}><text>
#  type : all, channel, server, private
#  (use /buffer localvar)
#
# Example:
# =======
# creates an option for a text item (nick_text), to use in all channel buffers:
#  /set plugins.var.python.text_item.nick_text channel ${yellow}Nicks:
#
# add the item "nick_text" to the bar.items (use auto-completion or iset.pl!)
# /set weechat.bar.status.items nick_text
#
# The text "Nicks:" will be displayed in the status bar (yellow colored!).
#
# Development is currently hosted at
# https://github.com/weechatter/weechat-scripts
