program a simple irc bot with ruby

In programming on 30 May 2007 with 13 comments

i spend my time learning socket programming in many languages such as c, c++, perl, ruby and etc.. but i like ruby most since it's easier to handle especially when i can use regular expression to manipulate strings sent by server. after reading through ruby's tutorial and understand a little bit of its concept i manage to code this simple ruby irc bot that can connect to irc and join a channel automatically. i also include some command to control the bot like ~join ~part ~say ~msg and ~quit to terminate the bot. it even have auto-jawab salam function..hehe

here's the code

print "ruby irc bot\\nbrought to you by novatechnhttp://wan.pengganas.net\\n"

require 'socket'
server = "java.webchat.org"
port = "6667"

bot = TCPSocket.open(server,port)
bot.send("USER novaBot novaBot novaBot :Written in Ruby ;) \\r\\n", 0)
bot.send("NICK botcapayam\\r\\nJOIN #database\\r\\n", 0)    

stay = 1
while stay == 1
    str = String.new(bot.readline) #i don't know why i did this
    #check if we have ping
    if /^PING :(.*)/.match(str)
        bot.send("PONG #$1\\r\\n", 0)
    end

    if /^:novatech!(.*)@(.*) PRIVMSG #(.*) :(.*)/.match(str)
        command = "#$3 #$4"
        bot.send("PRIVMSG ##$1 #$2\\r\\n", 0) if command =~ /(.*) ~say (.*)/
        bot.send("PRIVMSG #$2\\r\\n", 0) if command =~ /(.*) ~msg (.*)/
        bot.send("JOIN ##$2\\r\\n", 0) if command =~ /(.*) ~join (.*)/
        bot.send("PART ##$2\\r\\n", 0) if command =~ /(.*) ~part (.*)/
    	stay = 0 if command =~ /(.*) ~quit/
    end
    if /^:(.*)!(.*)@(.*) PRIVMSG #(.*) :(askum|assalamualaikum|akum|a'kum)/.match(str)
        bot.send("PRIVMSG ##$4 wa'alaikumussalam #$1\\r\\n", 0)
    end
#puts bot.readline // for debug purpose
end #end while
bot.close

yea~ i'm suck in regular expressing..lol~!!

download the source code if you can't copy code above properly

if you want to expend its features, then all you need to do is learn yourself how to manage strings in ruby...and of course a lot of regex practice hehe... see ya

to all banjirian peoples.. apa kata korang semua cuba try ekjas buat rimut tibai ruby plak? apa macam ada brani? aku dah cek... laju daripada rimut irc, tapi apakan daya aku dah pencen
