An extensible IRC bot implemented using C++11 and Boost.Asio.

By now the bot can connect to a IRC network, join channels, send private messages, change nick, op someone and quit. Here is a list of commands:

• /m subject message - send a message to the subject (#channel, nick, etc.)
• /n newnick - changes the bot's nickname
• /j #channel - tries to join the channel #channel
• /op nick #channel - Op nick in #channel
• /q message - quits leaving a message

In the code side, it is possible to add read handlers, for example:

bot.add_read_handler([&bot](const std::string& m) {
	std::istringstream iss(m);
	std::string from, type, to, msg;
	
	iss >> from >> type >> to >> msg;
	
	if (msg == ":!time") {
		std::time_t now = std::chrono::system_clock::to_time_t(
			std::chrono::system_clock::now());
			
		bot.message(to, std::ctime(&now));
	}
});

This method call adds a read handler (a lamda function which takes an const std::string as argument) to the bot which prints the current time whenever some user sends a !time message on a channel in which the bot is in.

Cleverbot requires some new features of C++11 and some libraries from Boost such as Boost.Asio and Boost.System.
