Informations about the package phergie-irc-client-react
phergie/phergie-irc-client-react
A bare-bones PHP-based IRC client library built on React.
Install
The recommended method of installation is through composer.
Design goals
- Minimalistic and extensible design
- Informative logging of client-server interactions
- Simple easy-to-understand API
Usage
This example makes the bot greet other users as they join any of the channels in which the bot is present.
- Create and configure an instance of the connection class,
\Phergie\Irc\Connection
, for each server the bot will connect to. See phergie-irc-connection documentation for more information on configuring connection objects. - Create an instance of the client class,
\Phergie\Irc\Client\React\Client
. - Call the client object's
on()
method any number of times, each time specifying an event to monitor and a callback that will be executed whenever that event is received from the server. - Call the client object's
run()
method with a connection object or array of multiple connection objects created in step #1.
Client Events
Below are the events supported by the client. Its on()
method can be used to add callbacks for them.
connect.before.all
Emitted before any connections are established.
Parameters
\Phergie\Irc\ConnectionInterface[] $connections
- array of all connection objects
Example
connect.after.all
Emitted after all connections are established.
Parameters
\Phergie\Irc\ConnectionInterface[] $connections
- array of all connection objects\Phergie\Irc\Client\React\WriteStream[] $writes
- corresponding array of connection write streams
Note that if a connection attempt failed, the value in $writes
for that connection will be null
.
Example
connect.before.each
Emitted before each connection is established.
Parameters
\Phergie\Irc\ConnectionInterface $connection
- object for the connection to be established
Example
connect.after.each
Emitted after each connection is established.
One potentially useful application of this is to institute a delay between connections in cases where the client is attempting to establish multiple connections to the same server and that server throttles connection attempts by origin to prevent abuse, DDoS attacks, etc.
Parameters
\Phergie\Irc\ConnectionInterface $connection
- object for the established connection\Phergie\Irc\Client\React\WriteStream|null $write
- write stream for the connection
Note that if the connection attempt failed, $write
will be null
.
Example
connect.error
Emitted when an error is encountered on a connection.
Parameters
Exception $exception
- exception describing the error that encountered\Phergie\Irc\ConnectionInterface $connection
- container that stores metadata for the connection on which the event occurred and implements the interface\Phergie\Irc\ConnectionInterface
(see its source code for a list of available methods)\Psr\Log\LoggerInterface $logger
- logger for logging any relevant events from the listener which go to stdout by default (see the Monolog documentation for more information)
Example
connect.end
Emitted when a connection is terminated.
This can be useful for re-establishing a connection if it is unexpectedly terminated.
Parameters
\Phergie\Irc\ConnectionInterface $connection
- container that stores metadata for the connection that was terminated and implements the interface\Phergie\Irc\ConnectionInterface
(see its source code for a list of available methods)\Psr\Log\LoggerInterface $logger
- logger for logging any relevant events from the listener which go to stdout by default (see the Monolog documentation for more information)
Example
irc.received
Emitted when an IRC event is received from the server.
Parameters
array $message
- associative array containing data for the event received from the server as obtained by\Phergie\Irc\Parser
(see its documentation for examples)\Phergie\Irc\Client\React\WriteStream $write
- stream that will send new events from the client to the server when its methods are called and implements the interface\Phergie\Irc\GeneratorInterface
(see its source code for a list of available methods)\Phergie\Irc\ConnectionInterface $connection
- container that stores metadata for the connection on which the event occurred and implements the interface\Phergie\Irc\ConnectionInterface
(see its source code for a list of available methods)\Psr\Log\LoggerInterface $logger
- logger for logging any relevant events from the listener which go to stdout by default (see the Monolog documentation for more information)
Example
irc.sent
Emitted when an IRC event is sent by the client to the server.
Parameters
string $message
- message being sent by the client\Phergie\Irc\Client\React\WriteStream $write
- stream that will send new events from the client to the server when its methods are called and implements the interface\Phergie\Irc\GeneratorInterface
(see its source code for a list of available methods)\Phergie\Irc\ConnectionInterface $connection
- container that stores metadata for the connection on which the event occurred and implements the interface\Phergie\Irc\ConnectionInterface
(see its source code for a list of available methods)\Psr\Log\LoggerInterface $logger
- logger for logging any relevant events from the listener which go to stdout by default (see the Monolog documentation for more information)
Example
irc.tick
Emitted periodically on each connection to allow events to be sent
asynchronously versus in response to received or sent events. The interval
between invocations is specified in seconds and set using the client's
setTickInterval()
method.
Parameters
\Phergie\Irc\Client\React\WriteStream $write
- stream that will send new events from the client to the server when its methods are called and implements the interface\Phergie\Irc\GeneratorInterface
(see its source code for a list of available methods)\Phergie\Irc\ConnectionInterface $connection
- container that stores metadata for the connection on which the event occurred and implements the interface\Phergie\Irc\ConnectionInterface
(see its source code for a list of available methods)\Psr\Log\LoggerInterface $logger
- logger for logging any relevant events from the listener which go to stdout by default (see the Monolog documentation for more information)
Example
Timers
In some cases, it's desirable to execute a callback on a specified interval rather than in response to a specific event.
One-Time Callbacks
To add one-time callbacks that execute after a specified amount of time (in seconds):
The above example will execute the specified callback at least 5 seconds after it's added.
Recurring Callbacks
To add recurring callbacks that execute on a specified interval (in seconds):
The above example will execute the specified callback at least every 5 seconds after it's added.
Connection Options
force-ip4
Connection sockets will use IPv6 by default where available. If you need to force usage of IPv4, set this option to true
.
allow-self-signed
By default all ssl connections only accept officially signed certificates. Sometimes you need to connect to a irc server that uses a self signed certificate. If you need to allow connections to servers using a self signed certificate, set this option to true
.
transport
By default, a standard TCP socket is used. For IRC servers that support TLS or SSL, specify an appropriate transport.
