IrcBotBundle

Installation

1. Download IrcBotBundle
2. Enable the bundle
3. Configure server, user
4. Launch the IrcBot!

Step 1: Download IrcBotBundle

{
    "require": {
        "whisller/irc-bot-bundle": "*"
    }
}

Now tell composer to download the bundle by running the command:

$ php composer.phar update whisller/irc-bot-bundle

Composer will install the bundle to your project's vendor/whisller directory.

Step 2: Enable the bundle

Enable the bundle in the kernel:

<?php
// app/AppKernel.php

public function registerBundles()
{
    $bundles = array(
        // ...
        new Whisnet\IrcBotBundle\WhisnetIrcBotBundle(),
    );
}

Step 3: Configure server, user

Basic configuration:

whisnet_irc_bot:
  user: ~
  channels: ["#test-irc"]

Advanced configuration:

whisnet_irc_bot:
    connection_class: Whisnet\IrcBotBundle\Connection\Socket
    host: irc.freenode.net
    port: 6667
    command_prefix: !bot
    user:
        username: IrcBotBunle
        mode: 8
        servername: IrcBotBundle
    channels: ["#test-irc", "#test-other-irc"]

Step 4: Launch the IrcBot!

$ php app/console irc:launch

Write your own bot's command.

1. Write listener
2. Register your listener
3. Use your command

When you want to write your own command it is really simple, because IrcBotBundle is working on Event Dispatcher.

So one thing you need to do is catch command event, and handle it.

Best way to learn something is to see how does it work. So lets write simple command, which will be saying "Hi {user}!"

Step 1: Write listener

<?php
namespace Acme\EventListener;

use Whisnet\IrcBotBundle\EventListener\Plugins\Commands\CommandListener;
use Whisnet\IrcBotBundle\Event\BotCommandFoundEvent;

class HelloListener extends CommandListener
{
    public function onCommand(BotCommandFoundEvent $event)
    {
        // get list of arguments passed after command
        $args = $event->getArguments();

        $msg = 'Hi, '.(isset($args[0]) ? $args[0] : 'nobody').' !';

        // write to the current channel
        $this->sendMessage(array($event->getChannel()), $msg);
    }
}

Step 2: Register your listener

<service id="whisnet_irc_bot.bot_command_hello_listener" class="Acme\EventListener\HelloListener">
    <tag name="whisnet_irc_bot.bot_command" command="hello" help="Say hello to user" arguments="(username)"/>
    <tag name="kernel.event_listener" event="whisnet_irc_bot.bot_command_hello" method="onCommand"/>
</service>

As you can see event name is "whisnet_irc_bot.bot_command_hello", bundle is listening on PRIVMSG message from server, then searching in it for string defined in "whisnet_irc_bot.command_prefix".

If the "whisnet_irc_bot.command_prefix" string gonna by found, then bundle is trying to parse everything after it to read command name and arguments for pass to "BotCommandFoundEvent".

E.g. "!bot hello whisller" will be parsed as:

• command: "hello"
• arg_0: "whisller"

And then it trigger an event "whisnet_irc_bot.bot_command_hello".

Step 3: Use your command

!bot hello whisller

Events list

IrcBotBundle events

whisnet_irc_bot.post_connection

This event is triggered after connection to the server is established. The example of use this event you can find in Whisnet\IrcBotBundle\EventListener\Plugins\Core\LoadUserCoreListener class.

Server events

Bundle is triggering events based on server messages. E.g.

whisnet_irc_bot.irc_command_PRIVMSG
whisnet_irc_bot.irc_command_MODE
whisnet_irc_bot.irc_command_372
whisnet_irc_bot.irc_command_NOTICE
whisnet_irc_bot.irc_command_391

and so on.

The event name is really simple, it is based on prefix "whisnet_irc_bot.irc_command_" and a type of message sent by server, e.g. "PRIVMSG". So you can listen on all events sent by server to make your own extends of bundle.

All list of commands you can find on http://tools.ietf.org/html/rfc2812

Bot commands

If Whisnet\IrcBotBundle\EventListener\Irc\Messages\PrivMsgListener::onData decide that message wrote on channel are a irc bot command then it trigger an event "whisnet_irc_bot.bot_command_COMMANDNAME" e.g. whisnet_irc_bot.bot_command_time, whisnet_irc_bot.bot_command_seen.
