NAME

Redis::Script - wrapper class for Redis' script

SYNOPSIS

# OO-interface
use Redis;
use Redis::Script;
my $script = Redis::Script->new(script => "return {KEYS[1],KEYS[2],ARGV[1],ARGV[2]}");
my ($key1, $key2, $arg1, $arg2) = $script->eval(Redis->new, ['key1', 'key2'], ['arg1', 'arg2']);

# Functional
use Redis::Script qw/redis_eval/;
my ($key1, $key2, $arg1, $arg2) = redis_eval(Redis->new, "return {KEYS[1],KEYS[2],ARGV[1],ARGV[2]}", ['key1', 'key2'], ['arg1', 'arg2']);

DESCRIPTION

Redis::Script is wrapper class for Redis' script.

FUNCTIONS

$script->eval($redis:Redis, $keys:ArrayRef, $args:ArrayRef)

eval executes the script by EVALSHA command. If EVALSHA reports "No matching script", use EVAL instead of EVALSHA. Redis will cache the script of EVAL command, so EVALSHA will succeed next time.

If use_evalsha option is false, eval does not use EVALSHA command.

$script->exists($redis:Redis)

exists reports if $redis caches the script.

$script->load($redis:Redis)

Load a script into the scripts cache, without executing it.
