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 support.

APIv1

Protocol::Redis APIv1 uses "Unified Request 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.
