# weestats.py, version 0.2 for WeeChat version 0.3
# Latest development version: https://github.com/FiXato/weechat_scripts
#
# Inserts some statistics into your input field about the buffers/windows
#  you have open.
# Example: 151 buffers (46 merged): 135 channels, 9 servers, 3 queries,
#  1 script, 1 python, 1 perl, 1 core; 3 windows
#
## History:
#
### 2012-03-29: FiXato:
# * version 0.1: initial release.
#     * Display a count of all the different buffers you have open.
#     * Display a count of all the open windows.
# * version 0.2: Getting the splits.
#     * Displays the how many vertical and horizontal windows.
#       (not quite sure if my approximation is correct though..)
#     * Fixed possible memleak (forgot to free an infolist)
### 2015-05-02: arza:
# * version 0.3:
#     * handle non-#-channels
#     * numerical sort for buffer info
#     * moved window split info to option -split
#     * simplified the output
#
## Acknowledgements:
# * Sebastien "Flashcode" Helleu, for developing the kick-ass chat/IRC
#    client WeeChat
#
## TODO:
#   - Add more statistics, such as:
#     - average and total history lines.
#     - average and total topic/title lengths
#     - how many are displayed in a window
