NAME
Redis - perl binding for Redis databaseDESCRIPTION
Pure perl bindings for <http://code.google.com/p/redis/>This version supports protocol 1.2 or later of Redis available at
<git://github.com/antirez/redis>
This documentation lists commands which are exercised in test suite, but additinal commands will work correctly since protocol specifies enough information to support almost all commands with same peace of code with a little help of "AUTOLOAD".
FUNCTIONS
new
my $r = Redis->new; # $ENV{REDIS_SERVER} or 127.0.0.1:6379 my $r = Redis->new( server => '192.168.0.1:6379', debug = 0 );
Connection Handling
quit
$r->quit;
ping
$r->ping || die "no server?";
Commands operating on string values
set
$r->set( foo => 'bar' ); $r->setnx( foo => 42 );
get
my $value = $r->get( 'foo' );
mget
my @values = $r->mget( 'foo', 'bar', 'baz' );
incr
$r->incr('counter'); $r->incrby('tripplets', 3);
decr
$r->decr('counter'); $r->decrby('tripplets', 3);
exists
$r->exists( 'key' ) && print "got key!";
del
$r->del( 'key' ) || warn "key doesn't exist";
type
$r->type( 'key' ); # = string
Commands operating on the key space
keys
my @keys = $r->keys( '*glob_pattern*' );
randomkey
my $key = $r->randomkey;
rename
my $ok = $r->rename( 'old-key', 'new-key', $new );
dbsize
my $nr_keys = $r->dbsize;
Commands operating on lists
See also Redis::List for tie interface.rpush
$r->rpush( $key, $value );
lpush
$r->lpush( $key, $value );
llen
$r->llen( $key );
lrange
my @list = $r->lrange( $key, $start, $end );
ltrim
my $ok = $r->ltrim( $key, $start, $end );
lindex
$r->lindex( $key, $index );
lset
$r->lset( $key, $index, $value );
lrem
my $modified_count = $r->lrem( $key, $count, $value );
lpop
my $value = $r->lpop( $key );
rpop
my $value = $r->rpop( $key );
Commands operating on sets
sadd
$r->sadd( $key, $member );
srem
$r->srem( $key, $member );
scard
my $elements = $r->scard( $key );
sismember
$r->sismember( $key, $member );
sinter
$r->sinter( $key1, $key2, ... );
sinterstore
my $ok = $r->sinterstore( $dstkey, $key1, $key2, ... );
Multiple databases handling commands
select
$r->select( $dbindex ); # 0 for new clients
move
$r->move( $key, $dbindex );
flushdb
$r->flushdb;
flushall
$r->flushall;
Sorting
sort
$r->sort("key BY pattern LIMIT start end GET pattern ASC|DESC ALPHA');
Persistence control commands
save
$r->save;
bgsave
$r->bgsave;
lastsave
$r->lastsave;
shutdown
$r->shutdown;
Remote server control commands
info
my $info_hash = $r->info;
ENCODING
Since Redis knows nothing about encoding, we are forcing utf-8 flag on all data received from Redis. This change is introduced in 1.2001 version.This allows us to round-trip utf-8 encoded characters correctly, but might be problem if you push binary junk into Redis and expect to get it back without utf-8 flag turned on.
