Redis::Scripted

A Ruby client that supports the experimental scripting feature in Redis.

Usage

Drop your Lua scripts in ./scripts:

scripts/
├── msadd.lua
└── sintercard.lua

Then initialize the connection to Redis, passing the path where the class should look for scripts:

require "redis/scripted"

redis = Redis::Scripted.connect(scripts_path: "./scripts")

The scripts are defined as instance methods for convenience:

redis.msadd(["foo"], ["s1", "s2", "s3"])

Note that msadd receives two arguments at most: one array for the keys and another for the values. This is necessary because of how EVAL works.

The class also exposes the eval and evalsha methods if you want to call them yourself.
