The irc component implements an IRC (Internet Relay Chat) transport.

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-irc</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>

URI format

irc:nick@host[:port]/#room[?options]
irc:nick@host[:port]?channels=#channel1,#channel2,#channel3[?options]

You can append query options to the URI in the following format, ?option=value&option=value&…​

Options

The IRC component has no options.

The IRC component supports 26 endpoint options which are listed below:

{% raw %}

NameGroupDefaultJava TypeDescription

hostname

common

 

String

Required Hostname for the IRC chat server

port

common

6667,6668,6669

int

Port number for the IRC chat server

autoRejoin

common

true

boolean

Whether to auto re-join when being kicked

namesOnJoin

common

false

boolean

Sends NAMES command to channel after joining it. link onReply has to be true in order to process the result which will have the header value irc.num = '353'.

nickname

common

 

String

The nickname used in chat.

persistent

common

true

boolean

Use persistent messages.

realname

common

 

String

The IRC user’s actual name.

bridgeErrorHandler

consumer

false

boolean

Allows for bridging the consumer to the Camel routing Error Handler which mean any exceptions occurred while the consumer is trying to pickup incoming messages or the likes will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions that will be logged at WARN/ERROR level and ignored.

exceptionHandler

consumer (advanced)

 

ExceptionHandler

To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this options is not in use. By default the consumer will deal with exceptions that will be logged at WARN/ERROR level and ignored.

exchangePattern

consumer (advanced)

 

ExchangePattern

Sets the exchange pattern when the consumer creates an exchange.

colors

advanced

true

boolean

Whether or not the server supports color codes.

synchronous

advanced

false

boolean

Sets whether synchronous processing should be strictly used or Camel is allowed to use asynchronous processing (if supported).

onJoin

filter

true

boolean

Handle user join events.

onKick

filter

true

boolean

Handle kick events.

onMode

filter

true

boolean

Handle mode change events.

onNick

filter

true

boolean

Handle nickname change events.

onPart

filter

true

boolean

Handle user part events.

onPrivmsg

filter

true

boolean

Handle private message events.

onQuit

filter

true

boolean

Handle user quit events.

onReply

filter

false

boolean

Whether or not to handle general responses to commands or informational messages.

onTopic

filter

true

boolean

Handle topic change events.

nickPassword

security

 

String

Your IRC server nickname password.

password

security

 

String

The IRC server password.

sslContextParameters

security

 

SSLContextParameters

Used for configuring security using SSL. Reference to a org.apache.camel.util.jsse.SSLContextParameters in the Registry. This reference overrides any configured SSLContextParameters at the component level. Note that this setting overrides the trustManager option.

trustManager

security

 

SSLTrustManager

The trust manager used to verify the SSL server’s certificate.

username

security

 

String

The IRC server user name.

{% endraw %}

SSL Support

Using the JSSE Configuration Utility

As of Camel 2.9, the IRC component supports SSL/TLS configuration through the Camel JSSE Configuration Utility.  This utility greatly decreases the amount of component specific code you need to write and is configurable at the endpoint and component levels.  The following examples demonstrate how to use the utility with the IRC component.

Programmatic configuration of the endpoint

KeyStoreParameters ksp = new KeyStoreParameters();
ksp.setResource("/users/home/server/truststore.jks");
ksp.setPassword("keystorePassword");

TrustManagersParameters tmp = new TrustManagersParameters();
tmp.setKeyStore(ksp);

SSLContextParameters scp = new SSLContextParameters();
scp.setTrustManagers(tmp);

Registry registry = ...
registry.bind("sslContextParameters", scp);

...

from(...)
    .to("ircs://camel-prd-user@server:6669/#camel-test?nickname=camel-prd&password=password&sslContextParameters=#sslContextParameters");

Spring DSL based configuration of endpoint

...
  <camel:sslContextParameters
      id="sslContextParameters">
    <camel:trustManagers>
      <camel:keyStore
          resource="/users/home/server/truststore.jks"
          password="keystorePassword"/>
    </camel:keyManagers>
  </camel:sslContextParameters>...
...
  <to uri="ircs://camel-prd-user@server:6669/#camel-test?nickname=camel-prd&password=password&sslContextParameters=#sslContextParameters"/>...

Using the legacy basic configuration options

You can also connect to an SSL enabled IRC server, as follows:

ircs:host[:port]/#room?username=user&password=pass

By default, the IRC transport uses SSLDefaultTrustManager. If you need to provide your own custom trust manager, use the trustManager parameter as follows:

ircs:host[:port]/#room?username=user&password=pass&trustManager=#referenceToMyTrustManagerBean

Using keys

Available as of Camel 2.2

Some irc rooms requires you to provide a key to be able to join that channel. The key is just a secret word.

For example we join 3 channels where as only channel 1 and 3 uses a key.

irc:nick@irc.server.org?channels=#chan1,#chan2,#chan3&keys=chan1Key,,chan3key

Getting a list of users of the channel

Using the namesOnJoin option one can invoke the IRC-NAMES command after the component has joined a channel. The server will reply with irc.num = 353. So in order to process the result the property onReply has to be true. Furthermore one has to filter the onReply exchanges in order to get the names.

For example we want to get all exchanges that contain the usernames of the channel:

from("ircs:nick@myserver:1234/#mychannelname?listOnJoin=true&onReply=true")
	.choice()
		.when(header("irc.messageType").isEqualToIgnoreCase("REPLY"))
			.filter(header("irc.num").isEqualTo("353"))
			.to("mock:result").stop();
