How to pretty print all values in a Redis database

Copydef pretty_print_redis(redis)
  redis.keys.each_with_object({}) do |key, hash|
    type = redis.type(key)

    hash[key] = case type
    when 'string'
      redis.get(key)
    when 'hash'
      redis.hgetall(key)
    when 'list'
      redis.lrange(key, 0, -1)
    when 'set'
      redis.smembers(key)
    when 'zset'
      redis.zrange(key, 0, -1, with_scores: true)
    else
      raise ArgumentError, "Unknown type #{type}"
    end
  end
end
