# idea by lasers@freenode.#weechat
#
# 2023-08-01: nils_2 (libera.#weechat)
#     0.6.1 : fix a timing problem when joining autojoin-channels (reported by thecdnhermit)
#
# 2021-05-05: Sébastien Helleu <flashcode@flashtux.org>
#       0.6 : add compatibility with XDG directories (WeeChat >= 3.2)
#
# 2018-08-08: nils_2, (freenode.#weechat)
#       0.5 : fix TypeError with python3.6
#
# 2017-04-14: nils_2 & FiXato, (freenode.#weechat)
#       0.4 : big rewrite:
#           : added extra hooks:
#           - query buffers are now also stored when opening/closing queries
#           - queries only restored on connect; no longer on every reconnect
#           : current buffer position is retained
#           : manual saving of query list (https://github.com/weechat/scripts/issues/196)
#
# 2015-02-27: nils_2, (freenode.#weechat)
#       0.3 : make script consistent with "buffer_switch_autojoin" option (idea haasn)
#
# 2013-11-07: nils_2, (freenode.#weechat)
#       0.2 : fix file not found error (reported by calcifea)
#           : make script compatible with Python 3.x
#
# 2013-07-26: nils_2, (freenode.#weechat)
#       0.1 : initial release
#
# script will create a config file (~./weechat/queryman.txt)
# format: "servername nickname" (without "")
#
# Development is currently hosted at
# https://github.com/weechatter/weechat-scripts
