# :title: linkbot management for rbot
#
# Author:: Giuseppe "Oblomov" Bilotta <giuseppe.bilotta@gmail.com>

#
# Based on an idea by hagabaka (Yaohan Chen <yaohan.chen@gmail.com>)
#
# This plugin is used to grab messages from eggdrops (or other bots) that link
# channels from different networks. For the time being, a PRIVMSG echoed by an
# eggdrop is assumed to be in the form:
# <eggdrop> (nick@network) text of the message
# and it's fed back to the message delegators.
#
# This plugin also shows how to create 'fake' messages from a plugin, letting
# the bot parse them.
#
# TODO a possible enhancement to the Irc framework could be to create 'fake'
# servers to make this even easier.
class LinkBot < Plugin
BotConfig.register BotConfigArrayValue.new('linkbot.nicks',
:default => [],
:desc => "Nick(s) of the bots that act as channel links across networks")
BotConfig.register BotConfigArrayValue.new('linkbot.message_patterns',
:default => ['^<(\S+?)@(\S+?)>\s+(.*)$', '^\((\S+?)@(\S+?)\)\s+(.*)$'],
:desc => "List of regexp which match linkbot messages; each regexp needs to have three captures, which in order are the nickname of the original speaker, network, and original message")
# TODO use template strings instead of regexp for user friendliness
# Initialize the plugin
def initialize
super
@message_patterns = @bot.config['linkbot.message_patterns'].map {|p|
Regexp.new(p)
}
end
# Main method
def listen(m)
linkbots = @bot.config['linkbot.nicks']
return if linkbots.empty?
return unless linkbots.include?(m.sourcenick)
return unless m.kind_of?(PrivMessage)
# Now we know that _m_ is a PRIVMSG from a linkbot. Let's split it
# in nick, network, message
if @message_patterns.any? {|p| m.message.match p}
# if the regexp doesn't contain all parts, the default values get used
new_nick = $1 || 'unknown_nick'
network = $2 || 'unknown_network'
message = $3 || 'unknown_message'
debug "#{m.sourcenick} reports that #{new_nick} said #{message.inspect} on #{network}"
# One way to pass the new message back to the bot is to create a PrivMessage
# and delegate it to the plugins
new_m = PrivMessage.new(@bot, m.server, m.server.user(new_nick), m.target, message)
@bot.plugins.delegate "listen", new_m
@bot.plugins.privmsg(new_m) if new_m.address?
## Another way is to create a data Hash with source, target and message keys
## and then letting the bot client :privmsg handler handle it
## Note that this will also create irclog entries for the fake PRIVMSG
## TODO we could probably add a :no_irc_log entry to the data passed to the
## @bot.client handlers, or something like that
# data = {
# :source => m.server.user(new_nick)
# :target => m.target
# :message => message
# }
# @bot.client[:privmsg].call(data)
end
