NAME

       "Net::Async::IRC" - use IRC with "IO::Async"

SYNOPSIS

          use Future::AsyncAwait;

          use IO::Async::Loop;
          use Net::Async::IRC;

          my $loop = IO::Async::Loop->new;

          my $irc = Net::Async::IRC->new(
             on_message_text => sub {
                my ( $self, $message, $hints ) = @_;

                print "$hints->{prefix_name} says: $hints->{text}\n";
             },
          );

          $loop->add( $irc );

          await $irc->login(
             nick => "MyName",
             host => "irc.example.org",
          );

          await $irc->do_PRIVMSG( target => "YourName", text => "Hello world!" );

          $loop->run;

DESCRIPTION

       This object class implements an asynchronous IRC client, for use in programs based on
       IO::Async.

       Most of the actual IRC message handling behaviour is implemented by the parent class
       Net::Async::IRC::Protocol.

       Most of the behaviour related to being an IRC client is implemented by the parent class
       Protocol::IRC::Client.

       The following documentation may make mention of these above two parent classes; the reader
       should make reference to them when required.

PARAMETERS

       The following named parameters may be passed to "new" or "configure":

       nick => STRING
       user => STRING
       realname => STRING
               Connection details. See also "connect", "login".

               If "user" is not supplied, it will default to either $ENV{LOGNAME} or the current
               user's name as supplied by "getpwuid()" or "Win32::LoginName()".

               If unconnected, changing these properties will set the default values to use when
               logging in.

               If logged in, changing the "nick" property is equivalent to calling "change_nick".
               Changing the other properties will not take effect until the next login.

       use_caps => ARRAY of STRING
               Attempts to negotiate IRC v3.1 CAP at connect time. The array gives the names of
               capabilities which will be requested, if the server supports them.

               If the "sasl" capability is requested and supported by the server, the "login"
               method will use that.

METHODS

       The following methods documented in an "await" expression return Future instances.

   connect
          $irc = await $irc->connect( %args );

       Connects to the IRC server. This method does not perform the complete IRC login sequence;
       for that see instead the "login" method. The returned Future will yield the $irc instance
       itself, to make chaining easier.

       host => STRING
               Hostname of the IRC server.

       service => STRING or NUMBER
               Optional. Port number or service name of the IRC server. Defaults to 6667.

       Any other arguments are passed into the underlying "IO::Async::Loop" "connect" method.

          $irc->connect( %args );

       The following additional arguments are used to provide continuations when not returning a
       Future.

       on_connected => CODE
               Continuation to invoke once the connection has been established. Usually used by
               the "login" method to perform the actual login sequence.

                  $on_connected->( $irc )

       on_error => CODE
               Continuation to invoke in the case of an error preventing the connection from
               taking place.

                  $on_error->( $errormsg )

   login
          $irc = await $irc->login( %args );

       Logs in to the IRC network, connecting first using the "connect" method if required. Takes
       the following named arguments:

       nick => STRING
       user => STRING
       realname => STRING
               IRC connection details. Defaults can be set with the "new" or "configure" methods.

       pass => STRING
               Server password to connect with.

       Any other arguments that are passed, are forwarded to the "connect" method if it is
       required; i.e. if "login" is invoked when not yet connected to the server.

          $irc->login( %args );

       The following additional arguments are used to provide continuations when not returning a
       Future.

       on_login => CODE
               A continuation to invoke once login is successful.

                  $on_login->( $irc )

       If the "sasl" capability was requested and is supported by the server, this will be used
       instead of the simple "USER/PASS" command combination.

       At the current version, only the "PLAIN" SASL mechanism is supported.

   change_nick
          $irc->change_nick( $newnick );

       Requests to change the nick. If unconnected, the change happens immediately to the stored
       defaults. If logged in, sends a "NICK" command to the server, which may suceed or fail at
       a later point.

IRC v3.1 CAPABILITIES

       The following methods relate to IRC v3.1 capabilities negotiations.

   caps_supported
          $caps = $irc->caps_supported;

       Returns a HASH whose keys give the capabilities listed by the server as supported in its
       "CAP LS" response. If the server ignored the "CAP" negotiation then this method returns
       "undef".

   cap_supported
          $supported = $irc->cap_supported( $cap );

       Returns a boolean indicating if the server supports the named capability.

   caps_enabled
          $caps = $irc->caps_enabled;

       Returns a HASH whose keys give the capabilities successfully enabled by the server as part
       of the "CAP REQ" login sequence. If the server ignored the "CAP" negotiation then this
       method returns "undef".

   cap_enabled
          $enabled = $irc->cap_enabled( $cap );

       Returns a boolean indicating if the client successfully enabled the named capability.

MESSAGE-WRAPPING METHODS

       The following methods are all inherited from Protocol::IRC::Client but are mentioned again
       for convenient. For further details see the documentation in the parent module.

       In particular, each method returns a Future instance.

   do_PRIVMSG
   do_NOTICE
          await $irc->do_PRIVMSG( target => $target, text => $text );

          await $irc->do_NOTICE( target => $target, text => $text );

       Sends a "PRIVMSG" or "NOITICE" command.
