Kooky IRC Client

Function code

This code is based on http://www.endoneight.com/29_lua-irc-bot . You will need the lua socket library http://www.tecgraf.puc-rio.br/~diego/professional/luasocket/

 local socket = require("socket")
 local io = io
 local string = string

 module("irc")
 local connection
 local host
 local port
 local channel
 local nickname
 local messages = {
       ptr = 0, 
       size = -1
 }

 function initialize(settings)
       host = settings.host
       port = settings.port
       nickname = settings.nickname
       channel = settings.channel
       connection = socket.tcp()
       connection:settimeout(1)
 end

 function connect()
       if connection == nil then
               connection = socket.tcp()
               connection:settimeout(1)
       end
       connection:connect(host, port)
       send("NICK "..nickname)
       send("USER Awesome 0 * :awesome-git")
 end

function disconnect()
       if connection ~= nil then
               connection:close()
       end
       connection = nil

 function read()

Usage

To use the module in awesome just require it in your rc.lua and set the host, port and the nickname of your client in a table

 require("irc")

 irc.settings = {}
 irc.settings.host = "irc.oftc.net"
 irc.settings.port = 6667
 irc.settings.nickname = "awesome"

 irc.initialize(irc.settings)
 irc.connect()

 awful.hooks.timer.register(10, function ()
       if irc.messages_size() > 0 then
               msg = irc.message()
               if msg ~= nil then
                       irc.popup = naughty.notify({ 
                               title = "IRC",
                               text = msg.nick..": "..msg.message, 
                               hover_timeout = 3, 
                               timeout = 10
                       })
               end
        end
 end)

 awful.hooks.timer.register(1, function ()
       irc.read()
 end)

Have Fun!
