Hoa is a modular, extensible and structured set of PHP libraries.
Moreover, Hoa aims at being a bridge between industrial and research worlds.

Hoa\Irc

Help on IRC Help on Gitter Documentation Board

This library allows to write an IRC client, and interact through listeners and simple methods.

Learn more.

Installation

With Composer, to include this library into your dependencies, you need to require hoa/irc:

$ composer require hoa/irc '~0.0'

For more installation procedures, please read the Source page.

Testing

Before running the test suites, the development dependencies must be installed:

$ composer install

Then, to run all the test suites:

$ vendor/bin/hoa test:run

For more information, please read the contributor guide.

Quick usage

We propose a quick overview of a simple client that joins a channel and interacts to mentions. Next, we will enhance this client with a WebSocket server to receive external messages.

Interact to mentions

The Hoa\Irc\Client proposes the following listeners: open, join, message, private-message, mention, other-message, ping, kick, invite and error.

In order to connect to an IRC server, we have to use a socket client, such as:

$uri    = 'irc://chat.freenode.net';
$client = new Hoa\Irc\Client(new Hoa\Socket\Client($uri));

Then, we attach our listeners. When the connexion will be opened, we will join a channel, for example #hoaproject with the Gordon username:

$client->on('open', function (Hoa\Event\Bucket $bucket) {
    $bucket->getSource()->join('Gordon', '#hoaproject');

    return;
});

Next, when someone will mention Gordon, we will answer What?:

$client->on('mention', function (Hoa\Event\Bucket $bucket) {
    $data    = $bucket->getData();
    $message = $data['message']; // do something with that.

    $bucket->getSource()->say(
        $data['from']['nick'] . ': What?'
    );

    return;
});

Finally, to run the client:

$client->run();

Include a WebSocket server

We can add a WebSocket server to receive external messages we will forward to the IRC client. Thus, the beginning of our program will look like:

$ircUri = 'irc://chat.freenode.net';
$wsUri  = 'ws://127.0.0.1:8889';

$group  = new Hoa\Socket\Connection\Group();
$client = new Hoa\Irc\Client(new Hoa\Socket\Client($ircUri));
$server = new Hoa\Websocket\Server(new Hoa\Socket\Server($wsUri));

$group[] = $server;
$group[] = $client;

Then, we will forward all messages received by the WebSocket server to the IRC client:

$server->on('message', function (Hoa\Event\Bucket $bucket) use ($client) {
    $data = $bucket->getData();
    $client->say($data['message']);

    return;
});

Finally, to run both the IRC client and WebSocket server:

$group->run();

To send a message to the WebSocket server, we can use a WebSocket client in CLI:

$ echo 'foobar' | hoa websocket:client -s 127.0.0.1:8889

Documentation

The hack book of Hoa\Irc contains detailed information about how to use this library and how it works.

To generate the documentation locally, execute the following commands:

$ composer require --dev hoa/devtools
$ vendor/bin/hoa devtools:documentation --open

More documentation can be found on the project's website: hoa-project.net.

irc's Issues

Support Common CTCP Commands

see http://en.wikipedia.org/wiki/Client-to-client_protocol for a short list, and http://www.irchelp.org/irchelp/rfc/ctcpspec.html for reference.

Extended support could include:

  • FINGER - Returns the user's full name, and idle time.
  • VERSION - The version and type of the client.
  • SOURCE - Where to obtain a copy of a client.
  • USERINFO - A string set by the user (never the client coder)
  • CLIENTINFO - Dynamic master index of what a client knows.
  • ERRMSG - Used when an error needs to be replied with.
  • PING - Used to measure the delay of the IRC network between clients.
  • TIME - Gets the local date and time from other clients.

Example?

Is there a working example of this IRC client?

Issue with `composer install` on the last version.

I've retrieved the last commits on master to work on the #22. When I ran composer install, I've got the problem detailed in hoaproject/Central#32.

I retrieved the hoa/core package because the hoa/stream used is 0.15.x. To make it works I needed to change the hoa/stream version constraint to : "hoa/socket": "~1.0".

With that change, everything is fine 😄.

Extract useful informations from connection URL

As mentioned in the PR #22, the Irc connection URL can contains a lot of details about the connection that must be done : nickname, password, channel...

We need to retrieve this URI information to use them in the connection. For the moment we are throwing away all additional informations given (authentication, channel...).

Irc RFCs :

The list of information that can be retrieved from URL: https://tools.ietf.org/html/draft-butcher-irc-url-04#section-2.1

keep a list of connected nick

this can be done by

  1. When you connect, note everyone in the channel.
  2. then just watch JOIN, PART, QUIT, KICK, NICK messages and update the list accordingly

Allow to add new command in Client::_run

For now, the only way to add commands in Client::_run is to extends this method, reparse message and call parent for base message.

Please provide a simple way to add custom commands (or/and implement all the base commands, see #14).

A good solution should be to add an empty method in Client (by exemple "manageCustomCommand") and call it in default case.

support /ping command

when I do /PING <bot_nick>, I do not receive the same message as when I do /PING nickserv for example.

You should add a "clock system"

It's impossible to do things periodically or at a given timestamp.

Imagine following modules:

  • quizz with a countdown ;
  • twitter that check periodically new tweets ;
  • todo manager that alert you just before due date ;
  • etc...

Infinite loop when server fails

Sometimes, our bot has a peak to 100% CPU because of a server disconnection. Hard to reproduce… Does anyone have met this situation?
