# UrlGrab, version 1.3 for weechat version 0.2.6
#   Listens to all channels for URLs, collects them in a list, and launches
#   them in your favourite web server on the local host or a remote server.
#   Copies url to X11 clipboard via xsel
#      (http://www.vergenet.net/~conrad/software/xsel)
#   The /url command provides access to all UrlGrab functions.  Run
#   '/url help' for complete command usage.
#   In general, use '/url list' to list the entire url list for the current
#   channel, and '/url <n>' to launch the nth url in the list.  For
#   example, to launch the first (and most-recently added) url in the list,
#   you would run '/url 1'
#   From the server window, you must specify a specific channel for the
#   list and launch commands, for example:
#     /url list #weechat 
#     /url 3 #weechat
# Configuration:
#   The '/url set' command lets you get and set the following options:
#   historysize
#     The maximum number of URLs saved per channel.  Default is 10
#     Must be one of 'local' or 'remote' - Defines how URLs are launched by
#     the script.  If 'local', the script will run 'localcmd' on the host.
#     If 'remote', the script will run 'remotessh remotehost remotecmd' on
#     the local host which should normally use ssh to connect to another
#     host and run the browser command there.
#   localcmd
#     The command to run on the local host to launch URLs in 'local' mode.
#     The string '%s' will be replaced with the URL.  The default is
#     'firefox %s'.
#   remotessh
#     The command (and arguments) used to connect to the remote host for
#     'remote' mode.  The default is 'ssh -x' which will connect as the
#     current username via ssh and disable X11 forwarding.
#   remotehost
#     The remote host to which we will connect in 'remote' mode.  For ssh,
#     this can just be a hostname or 'user@host' to specify a username
#     other than your current login name.  The default is 'localhost'.
#   remotecmd
#     The command to execute on the remote host for 'remote' mode.  The
#     default is 'bash -c "DISPLAY=:0.0 firefox %s"'  Which runs bash, sets
#     up the environment to display on the remote host's main X display,
#     and runs firefox.  As with 'localcmd', the string '%s' will be
#     replaced with the URL.
#   cmdoutput
#     The file where the command output (if any) is saved.  Overwritten
#     each time you launch a new URL.  Default is ~/.weechat/urllaunch.log
#   default
#     The command that will be run if no arguemnts to /url are given.
#     Default is help
# Requirements:
#  - Designed to run with weechat version 0.2.4 or better.
#      http://weechat.flashtux.org/
# Acknowlegements:
#  - Based on an earlier version called 'urlcollector.py' by 'kolter' of
#    irc.freenode.net/#weechat Honestly, I just cleaned up the code a bit and
#    made the settings a little more useful (to me).
#  - With changes by Leonid Evdokimov (weechat at darkk dot net another dot ru):
#    http://darkk.net.ru/weechat/urlgrab.py
#    v1.1:  added better handling of dead zombie-childs
#           added parsing of private messages
#           added default command setting
#           added parsing of scrollback buffers on load
#    v1.2:  `historysize` was ignored
#  - With changes by ExclusivE (exclusive_tm at mail dot ru):
#    v1.3: X11 clipboard support
