NAME
AnyEvent::Redis - Non-blocking Redis client SYNOPSIS
use AnyEvent::Redis; my $redis = AnyEvent::Redis->new( host => '127.0.0.1', port => 6379, encoding => 'utf8', on_error => sub { warn @_ }, ); # callback based $redis->set( 'foo'=> 'bar', sub { warn "SET!" } ); $redis->get( 'foo', sub { my $value = shift } ); my ($key, $value) = ('list_key', 123); $redis->lpush( $key, $value ); $redis->lpop( $key, sub { my $value = shift }); # condvar based my $cv = $redis->lpop( $key ); $cv->cb(sub { my $value = $_[0]->recv }); DESCRIPTION
AnyEvent::Redis is a non-blocking (event-driven) Redis client. This module is an AnyEvent user; you must install and use a supported event loop. ESTABLISHING A CONNECTION
To create a new connection, use the new() method with the following attributes: host => <HOSTNAME> Required. The hostname or literal address of the server. port => <PORT> Optional. The server port. encoding => <ENCODING> Optional. Encode and decode data (when storing and retrieving, respectively) according to ENCODING ("utf8" is recommended or see Encode::Supported for details on possible ENCODING values). Omit if you intend to handle raw binary data with this connection. on_error => $cb->($errmsg) Optional. Callback that will be fired if a connection or database-level error occurs. The error message will be passed to the callback as the sole argument. METHODS
All methods supported by your version of Redis should be supported. Normal commands There are two alternative approaches for handling results from commands: o AnyEvent::CondVar based: my $cv = $redis->command( # arguments to command ); # Then... my $res; eval { # Could die() $res = $cv->recv; }; warn $@ if $@; # or... $cv->cb(sub { my($cv) = @_; my($result, $err) = $cv->recv }); o Callback: $redis->command( # arguments, sub { my($result, $err) = @_; }); (Callback is a wrapper around the $cv approach.) Subscriptions The subscription methods ("subscribe" and "psubscribe") must be used with a callback: my $cv = $redis->subscribe("test", sub { my($message, $channel[, $actual_channel]) = @_; # ($actual_channel is provided for pattern subscriptions.) }); The $cv condition will be met on unsubscribing from the channel. Due to limitations of the Redis protocol the only valid commands on a connection with an active subscription are subscribe and unsubscribe commands. Common methods o get o set o hset o hget o lpush o lpop The Redis command reference (<http://redis.io/commands>) lists all commands Redis supports. REQUIREMENTS
This requires Redis >= 1.2. COPYRIGHT
