-#   Helper script for IRC Channel Operators
-#
-#   Inspired by auto_bleh.pl (irssi) and chanserv.py (xchat) scripts.
-#
-#   Networks like Freenode and some channels encourage operators to not stay
-#   permanently with +o privileges and only use it when needed. This script
-#   works along those lines, requesting op, kick/ban/etc and deop
-#   automatically with a single command.
-#   Still this script is very configurable and its behaviour can be configured
-#   in a per server or per channel basis so it can fit most needs without
-#   changing its code.
-#
-#   Features several completions for ban/quiet masks and a memory for channel
-#   masks and users (so users that parted are still bannable by nick).
-#
-#
-#   Commands (see detailed help with /help in WeeChat):
-#   *      /oop: Request or give op.
-#   *    /odeop: Drop or remove op.
-#   *    /okick: Kick user (or users).
-#   *     /oban: Apply ban mask.
-#   *   /ounban: Remove ban mask.
-#   *   /oquiet: Apply quiet mask.
-#   * /ounquiet: Remove quiet mask.
-#   * /obankick: Ban and kick user (or users)
-#   *   /otopic: Change channel topic
-#   *    /omode: Change channel modes
-#   *    /olist: List cached masks (bans or quiets)
-#   *   /ovoice: Give voice to user
-#   * /odevoice: Remove voice from user
-#
-#
-#   Settings:
-#   Most configs (unless noted otherwise) can be defined for a server or a
-#   channel in particular, so it is possible to request op in different
-#   networks, stay always op'ed in one channel while
-#   auto-deop in another.
-#
-#   For define an option for a specific server use:
-#   /set plugins.var.python.chanop.<option>.<server> "value"
-#   For define it in a specific channel use:
-#   /set plugins.var.python.chanop.<option>.<server>.<#channel> "value"
-#
-#   * plugins.var.python.chanop.op_command:
-#     Here you define the command the script must run for request op, normally
-#     is a /msg to a bot, like chanserv in freenode or Q in quakenet.
-#     It accepts the special vars $server, $channel and $nick
-#
-#     By default it ask op to chanserv, if your network doesn't use chanserv,
-#     then you must change it.
-#
-#     Examples:
-#     /set plugins.var.python.chanop.op_command
-#          "/msg chanserv op $channel $nick"
-#     (globally for all servers, like freenode and oftc)
-#     /set plugins.var.python.chanop.op_command.quakenet
-#          "/msg q op $channel $nick"
-#     (for quakenet only)
-#
-#   * plugins.var.python.chanop.autodeop:
-#     Enables auto-deop'ing after using any of the ban or kick commands.
-#     Note that if you got op manually (like with /oop) then the script won't
-#     deop you.
-#     Valid values: 'on', 'off' Default: 'on'
-#
-#   * plugins.var.python.chanop.autodeop_delay:
-#     Time it must pass (without using any commands) before auto-deop, in
-#     seconds. Using zero causes to deop immediately.
-#     Default: 180
-#
-#   * plugins.var.python.chanop.default_banmask:
-#     List of keywords separated by comas. Defines default banmask, when using
-#     /oban, /obankick or /oquiet
-#     You can use several keywords for build a banmask, each keyword defines how
-#     the banmask will be generated for a given hostmask, see /help oban.
-#     Valid keywords are: nick, user, host and exact.
-#     Default: 'host'
-#
-#     Examples:
-#     /set plugins.var.python.chanop.default_banmask host
-#     (bans with *!*@host)
-#     /set plugins.var.python.chanop.default_banmask host,user
-#     (bans with *!user@host)
-#
-#   * plugins.var.python.chanop.kick_reason:
-#     Default kick reason if none was given in the command.
-#
-#   * plugins.var.python.chanop.enable_remove:
-#     If enabled, it will use "/quote remove" command instead of /kick, enable
-#     it only in networks that support it, like freenode.
-#     Valid values: 'on', 'off' Default: 'off'
-#
-#     Example:
-#     /set plugins.var.python.chanop.enable_remove.freenode on
-#
-#   * plugins.var.python.chanop.display_affected:
-#     Whenever a new ban is set, chanop will show the users affected by it.
-#     This is intended for help operators to see if their ban is too wide or
-#     point out clones in the channel.
-#     Valid values: 'on', 'off' Default: 'off'
-#
-#
-#   The following configs are global and can't be defined per server or channel.
-#
-#   * plugins.var.python.chanop.enable_multi_kick:
-#     Enables kicking multiple users with /okick command.
-#     Be careful with this as you can kick somebody by accident if
-#     you're not careful when writting the kick reason.
-#
-#     This also applies to /obankick command, multiple bankicks would be enabled.
-#     Valid values: 'on', 'off' Default: 'off'
-#
-#   * plugins.var.python.chanop.enable_bar:
-#     This will enable a pop-up bar for displaying chanop messages that would
-#     otherwise be printed in the buffer. This bar also shows in realtime the
-#     users affected by a ban you're about to set.
-#     Valid values: 'on', 'off' Default: 'on'
-#
-#
-#   The following configs are defined per server and are updated by the script only.
-#
-#   * plugins.var.python.chanop.watchlist:
-#     Indicates to chanop which channels should watch and keep track of users and
-#     masks. This config is automatically updated when you use any command that needs
-#     op, so manual setting shouldn't be needed.
-#
-#   * plugins.var.python.chanop.isupport:
-#     Only used in WeeChat versions prior to 0.3.3 which lacked support for
-#     irc_005 messages. These aren't meant to be set manually.
-#
-#
-#   Completions:
-#     Chanop has several completions, documented here. Some aren't used by chanop
-#     itself, but can be used in aliases with custom completions.
-#     Examples:
-#     apply exemptions with mask autocompletion
-#     /alias -completion %(chanop_ban_mask) exemption /mode $channel +e
-#     if you use grep.py script, grep with host autocompletion, for look clones.
-#     /alias -completion %(chanop_hosts) ogrep /grep
-#
-#   * chanop_unban_mask (used in /ounban)
-#     Autocompletes with banmasks set in current channel, requesting them if needed.
-#     Supports patterns for autocomplete several masks: *<tab> for all bans, or
-#     *192.168*<tab> for bans with '192.168' string.
-#
-#   * chanop_unquiet (used in /ounquiet)
-#     Same as chanop_unban_mask, but with masks for q channel mode.
-#
-#   * chanop_ban_mask (used in /oban and /oquiet)
-#     Given a partial IRC hostmask, it will try to complete with hostmasks of current
-#     users: *!*@192<tab> will try to complete with matching users, like
-#     *!*@192.168.0.1
-#
-#   * chanop_nicks (used in most commands)
-#     Autocompletes nicks, same as WeeChat's completer, but using chanop's user
-#     cache, so nicks from users that parted the channel will be still be completed.
-#
-#   * chanop_users (not used by chanop)
-#     Same as chanop_nicks, but with the usename part of the hostmask.
-#
-#   * chanop_hosts (not used by chanop)
-#     Same as chanop_nicks, but with the host part of the hostmask (includes previously used
-#     hostnames).
-#
-#
-#   TODO
-#   * use dedicated config file like in urlgrab.py?
-#   * ban expire time
-#   * save ban.mask and ban.hostmask across reloads
-#   * allow to override quiet command (for quiet with ChanServ)
-#   * freenode:
-#    - support for bans with channel forward
-#    - support for extbans (?)
-#   * Sort completions by user activity
-#
-#
-#   History:
-#   2013-05-24
-#   version 0.3.1: bug fixes

-#   * added pop-up bar for show information.
-#   * save ban mask information (date and operator)
-#   * remove workarounds for < 0.3.2 weechat versions
-#   * python 3.0 compatibility (not tested)
-#
-#   2013-01-02
-#   version 0.2.7: bug fixes:
-#   * fix /obankick, don't deop before kicking.
-#
-#   2011-09-18
-#   version 0.2.6: bug fixes:
-#   * update script to work with freenode's new quiet messages.
-#   * /omode wouldn't work with several modes.
-#
-#   2011-05-31
-#   version 0.2.5: bug fixes:
-#   * /omode -o nick wouldn't work due to the deopNow switch.
-#   * unban_completer could fetch the same masks several times.
-#   * removing ban forwards falied when using exact mask.
-#   * user nick wasn't updated in every call.
-#
-#   2011-02-02
-#   version 0.2.4: fix python 2.5 compatibility
-#
-#   2011-01-09
-#   version 0.2.3: bug fixes.
-#
-#   2010-12-23
-#   version 0.2.2: bug fixes.
-#
-#   2010-10-28
-#   version 0.2.1: refactoring mostly
-#   * deop_command option removed
-#   * removed --webchat switch, freenode's updates made it superfluous.
-#   * if WeeChat doesn't know a hostmask, use /userhost or /who if needed.
-#   * /oban and /oquiet without arguments show ban/quiet list.
-#   * most commands allows '-o' option, that forces immediate deop (without configured delay).
-#   * updated for WeeChat 0.3.4 (irc_nick infolist changes)
-#
-#   2010-09-20
-#   version 0.2: major update
-#   * fixed quiets for ircd-seven (freenode)
-#   * implemented user and mask cache.
-#   * added commands:
-#     - /ovoice /odevoice for de/voice users.
-#     - /omode for change channel modes.
-#     - /olist for list bans/quiets on cache.
-#   * changed /omute and /ounmute commands to /oquiet and /ounquiet, as q masks
-#     is refered as a quiet rather than a mute.
-#   * autocompletions:
-#     - for bans set on a channel.
-#     - for make new bans.
-#     - for nicks/usernames/hostnames.
-#   * /okban renamed to /obankick. This is because /okban is too similar to
-#     /okick and bankicking somebody due to tab fail was too easy.
-#   * added display_affected feature.
-#   * added --webchat ban option.
-#   * config options removed:
-#     - merge_bans: superseded by isupport methods.
-#     - enable_mute: superseded by isupport methods.
-#     - invert_kickban_order: now is fixed to "ban, then kick"
-#   * Use WeeChat isupport infos.
-#   * /oop and /odeop can op/deop other users.
-#
-#   2009-11-9
-#   version 0.1.1: fixes
-#   * script renamed to 'chanop' because it was causing conflicts with python
-#     'operator' module
-#   * added /otopic command
-#
-#   2009-10-31
-#   version 0.1: Initial release

+# ListBuffer, version 0.8.1 for WeeChat version 0.3
+# Latest development version: https://github.com/FiXato/listbuffer
+#
+#   Show /list results in a common buffer and interact with them.
+#
+#   This script allows you to easily join channels from the /list output.
+#   It will open a common buffer for the /list result, through which you
+#   browse with your cursor keys, and join with the meta-enter keys.
+#   Adjust sorting with meta->, meta-< and meta-/ keybindings.
+#
+## History:
+### 2011-09-08: FiXato:
+#
+# * version 0.1:  initial release.
+#     * added a common buffer for /list results
+#     * added highlighting for currently selected line
+#     * added /join support via enter key
+#     * added scroll_top and scroll_bottom support
+#
+# * version 0.2:  /list format bugfix
+#     * added support for /list results without modes
+#     * some servers don't send 321 (/list start). Taken into account.
+#
+# * version 0.3: Sorting support
+#     * Added some basic sorting support. Scroll through sort options
+#       with meta-> and meta-< (users, channel, topic, modes)
+#
+### 2011-09-19: FiXato
+#
+# * version 0.4:
+#     * Case-insensitive buffer lookup fix.
+#     * Removed default enter keybind
+#
+### 2011-12-28: troydm:
+#
+# * version 0.5: It's an upside-down-world
+#     * Added inverted sorting support provided by Dmitry "troydm" Geurkov
+#       Use meta-/ to switch between inverted and regular sorting.
+#
+### 2012-02-10: FiXato:
+#
+# * version 0.6: Stop shoving that buffer in my face!
+#     * The listbuffer should no longer pop up by itself when you load the script.
+#       It should only pop up now when you actually do a /list query.
+#
+# * version 0.7: .. but please pop it up in my current window when I ask for it
+#     * Added setting plugins.var.python.listbuffer.autofocus
+#       This will autofocus the listbuffer in the current window if another window isn't
+#       already showing it, and of course only when the user issues /list
+#
+### 2012-07-10: FiXato:
+#
+# * version 0.7.1: Forgetful bugfix
+#     * Made sure lb_curline global variable is defined
+#
+### 2013-03-19: FiXato:
+#
+# * version 0.8: Sorted out the sorting
+#     * Added automatically updating options for sorting:
+#       * plugins.var.python.listbuffer.sort_inverted
+#       * plugins.var.python.listbuffer.sort_order
+# * version 0.8.1: Pad it baby!
+#     * Channel modes are equally padded even when there are no channel modes.
+#     * Added padding options:
+#       * plugins.var.python.listbuffer.modes_min_width
+#       * plugins.var.python.listbuffer.channel_min_width
+#       * plugins.var.python.listbuffer.users_min_width
+#
+## Acknowledgements:
+# * Dmitry "troydm" Geurkov, for providing the inverse-sorting patch to the project.
+# * Sebastien "Flashcode" Helleu, for developing the kick-ass IRC client WeeChat
+#    and the iset.pl script which inspired me to this script.
+# * Nils "nils_2" Görs, for his contributions to iset.pl which served as
+#    example code.
+# * David "drubin" Rubin, for his urlgrab.py script, which also served
+#    as example code.
+# * ArZa, whose listsort.pl script helped me getting started with
+#    grabbing the /list results. Parts of his code have been shamelessly
+#    copied and ported to Python.
+# * Khaled Mardam-Bey, for making me yearn for similar /list support in
+#    WeeChat as mIRC already offered. :P
+# * mave_, for pointing out that sort orders weren't remembered.
+#
+## TODO:
+#   - Auto-scroll selected line upon window scroll.
+#   - Add option to hide already joined channels.
+#   - Improve sorting methods
+#   - Add auto-join support
+#   - Detect if channel is already in auto-join
+#   - Allow automatically switching to the listbuffer
+#   - Add support for ALIS (/squery alis LIST * -mix 100 (IRCNet)
+#   - Make colours configurable
+#   - Limit number of channels to parse
+#   - Add filter support a la iset
+#   - Allow selecting multiple channels
+#   - Add optional command redirection.
