NAME
    Protocol::Redis - Redis protocol parser/encoder with asynchronous
    capabilities.

SYNOPSIS
        use Protocol::Redis;
        my $redis = Protocol::Redis->new(api => 1) or die "API v1 not supported";

        $redis->parse("+foo\r\n");

        # get parsed message
        my $message = $redis->get_message;
        print "parsed message: ", $message->{data}, "\n";

        # asynchronous parsing interface
        $redis->on_message(sub {
            my ($redis, $message) = @_;
            print "parsed message: ", $message->{data}, "\n";
        });

        # parse pipelined message
        $redis->parse("+bar\r\n-error\r\n");

        # create message
        print "Get key message:\n",
          $redis->encode({type => '*', data => [
             {type => '$', data => 'string'},
             {type => '+', data => 'OK'}
        ]});

DESCRIPTION
    Redis protocol parser/encoder with asynchronous capabilities and
    pipelining <http://redis.io/topics/pipelining> support.

APIv1
    Protocol::Redis APIv1 uses "Unified Request Protocol
    <http://redis.io/topics/protocol>" for message encoding/parsing and
    supports methods described further. Client libraries should specify API
    version during Protocol::Redis construction.

  "new"
        my $redis = Protocol::Redis->new(api => 1)
            or die "API v1 not supported";

    Construct Protocol::Redis object with specific API version support. If
    specified API version not supported constructor returns undef. Client
    libraries should always specify API version.

  "parse"
        $redis->parse("*2\r\n$4ping\r\n\r\n");

    Parse Redis protocol chunk.

  "get_message"
        while (my $message = $redis->get_message) {
            ...
        }

    Get parsed message or undef.

  "on_message"
        $redis->on_message(sub {
            my ($redis, $message) = @_;

        }

    Calls callback on each parsed message.

  "encode"
        my $string = $redis->encode({type => '+', data => 'test'});
        $string = $redis->encode(
            {type => '*', data => [
                {type => '$', data => 'test'}]});

    Encode data into redis message.

  "api"
        my $api_version = $redis->api;

    Get API version.
