#irc

A very basic IRC library and client (bot).

For hobby purposes, not production ready.

Unclear if the network code is any good.

#Tutorial

Install:

composer require thirdplace/irc:dev-main

Examples:

// non-tls
$config = [
    'server'    => 'irc.libera.chat',
    'protocol'  => 'tcp',
    'port'      => 6667,
    'nick'      => 'botson45',
    'channels'  => ['#test'],
];
$client = new \Thirdplace\Irc\Client($config);
$client->start();

// tls
$libera = [
    'server'    => 'irc.libera.chat',
    'protocol'  => 'tls',
    'port'      => 6697,
    'nick'      => 'botson45',
    'channels'  => ['#test'],
];
$client = new \Thirdplace\Irc\Client($config);
$client->start();

// tls with SASL authentication
$libera2 = [
    'server'    => 'irc.libera.chat',
    'protocol'  => 'tls',
    'port'      => 6697,
    'nick'      => 'botson45',
    'user'      => 'botson45',
    'auth'      => 'sasl',
    'password'  => 'REPLACE ME',
    'channels' => ['#test'],
];
$client = new \Thirdplace\Irc\Client($config);
$client->start();

// tls with twitch authentication (oauth)
$twitch = [
    'server'    => 'irc.chat.twitch.tv',
    'protocol'  => 'tls',
    'port'      => 6697,
    'nick'      => 'botson45',
    'auth'      => 'twitch',
    'token'     => 'REPLACE ME',
    'channels'  => ['#hasanbi'],
];
$client = new \Thirdplace\Irc\Client($config);
$client->start();

Run unit tests:

./vendor/bin/phpunit --bootstrap=vendor/autoload.php ./test

#How-to

#How to create a command

// Respond to !hello command with 'world'
$client->addHandler(function(Client $client, Message $message) {
    if (
        $message->isChannelMessage()
        && preg_match('/^!hello/', $message->getMessageParameter())
    ) {
        $client->write($message->reply('world'));
    }
});

#How to run handler each 10 seconds

// Write a tick message to #test3 each 10 seconds
$client->addTickHandler(10, function(Client $client) {
    $client->write(Message::privmsg('#test3', 'tick!'));
});

#How to send raw text to server

Create client wite pipe_file config:

$config = [
    'server'    => 'irc.libera.chat',
    'protocol'  => 'tcp',
    'port'      => 6667,
    'nick'      => 'botson45',
    'channels'  => ['#test3'],
    'pipe_file' => '/tmp/irc',
];
$client = new \Thirdplace\Irc\Client($config);
$client->start();

Write to it from shell:

echo "PRIVMSG #test3 :hello world" > /tmp/irc

#Explanation

The code base is small. Start with src/Client.php to get a feel.

The majority of the irc logic is in Message.php. The client is in Client.php. The src/handlers folder contains code to be invoked based off of passing irc messages.

#Reference

Client config:

$defaults = [
    'server'    => 'irc.libera.chat',
    'protocol'  => 'tls', // ['tcp', 'tls']
    'port'      => 6697,
    'auth'      => null, // [null, 'nickserv', 'sasl', 'twitch']
    'nick'      => null,
    'user'      => null,
    'password'  => null, // for NickServer or SASL
    'token'     => null, // oauth auth token (twitch.tv et al)
    'channels'  => [], // List of channels to join
    'pipe_file' => null, // Write raw text to server
];

Handler interface:

interface Handler
{
    public function __invoke(Client $client, Message $message): void;
}

Base exception:

final class IrcException extends \Exception
{
}
