lib/AnyEvent/Lingr.pm  view on Meta::CPAN

Update joined room info, and fire on_room_info callback.
This method also update subscription rooms which is target room for on_event callback.

=head2 say($room, $message [, $cb ])

Say something to lingr room.

    $lingr->say('perl_jp', 'hi!');

If you want response data, you can speficy callback.
The callback is invoked when the API call was successful.

    $lingr->say('perl_jp', 'hi there!', sub {
        my $res = shift;
        warn $res->{message}->{id};
    });

=head1 CALLBACKS

This module supports following three callbacks:

=over

=item * on_error->($msg)

=item * on_room_info->($rooms)

=item * on_event->($event)

=back

All callbacks can be set by accessor:

    $lingr->on_error(sub { ... });

Or by constructor:

    my $lingr = AnyEvent::Lingr->new(
        ...
        on_error => sub { ... },
    );

=head2 on_error->($msg)

Error callbacks.

C<$msg> is error message. If this message is form of "\d\d\d: message" like:

    595: Invalid argument

This is http level or connection level error. Otherwise C<$msg> is error message returned from lingr api server.

Both case, lingr session was closed before this callback, so you can restart session in this callback:

    $lingr->on_error(sub {
        my ($msg) = @_;
        warn 'Lingr error: ', $msg;
    
        # reconnect after 5 seconds,
        my $t; $t = AnyEvent->timer(
            after => 5,
            cb    => sub {
                $lingr->start_session;
                undef $t;
            },
        );
    });

=head2 on_room_info->($rooms)

Fired when after start_session or after update_room_info method.

C<$rooms> is ArrayRef of room information you joined.

=head2 on_event->($event)

Fired when some events is occurred in your subscribed rooms.
