Module irc

LuaIRC is a low-level IRC library for Lua. All functions raise Lua exceptions on error. Use new to create a new IRC object.
Example:
require "irc"
local sleep = require "socket".sleep
local s = irc.new{nick = "example"}
s:hook("OnChat", function(user, channel, message)
print(("[%s] %s: %s"):format(channel, user.nick, message))
end)
s:connect("irc.example.net")
s:join("#example")
while true do
s:think()
sleep(0.5)
end
