NAME

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

SYNOPSIS

use Protocol::Redis;
my $redis = Protocol::Redis->new(api => 1);

$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);

Construct Protocol::Redis object with specific API version support. If specified API version not supported constructor should raise an exception. 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.
