Installation
------------

Install:

    go get gopkg.in/redis.v3

Quickstart
----------

```go
func ExampleNewClient() {
	client := redis.NewClient(&redis.Options{
		Addr:     "localhost:6379",
		Password: "", // no password set
		DB:       0,  // use default DB
	})

	pong, err := client.Ping().Result()
	fmt.Println(pong, err)
	// Output: PONG <nil>
}

func ExampleClient() {
	err := client.Set("key", "value", 0).Err()
	if err != nil {
		panic(err)
	}

	val, err := client.Get("key").Result()
	if err != nil {
		panic(err)
	}
	fmt.Println("key", val)

	val2, err := client.Get("key2").Result()
	if err == redis.Nil {
		fmt.Println("key2 does not exists")
	} else if err != nil {
		panic(err)
	} else {
		fmt.Println("key2", val2)
	}
	// Output: key value
	// key2 does not exists
}
```

Look and feel
-------------

Some corner cases:

    SET key value EX 10 NX
    set, err := client.SetNX("key", "value", 10*time.Second).Result()

    SORT list LIMIT 0 2 ASC
    vals, err := client.Sort("list", redis.Sort{Offset: 0, Count: 2, Order: "ASC"}).Result()

    ZRANGEBYSCORE zset -inf +inf WITHSCORES LIMIT 0 2
    vals, err := client.ZRangeByScoreWithScores("zset", redis.ZRangeByScore{
        Min: "-inf",
        Max: "+inf",
        Offset: 0,
        Count: 2,
    }).Result()

    ZINTERSTORE out 2 zset1 zset2 WEIGHTS 2 3 AGGREGATE SUM
    vals, err := client.ZInterStore("out", redis.ZStore{Weights: []int64{2, 3}}, "zset1", "zset2").Result()

    EVAL "return {KEYS[1],ARGV[1]}" 1 "key" "hello"
    vals, err := client.Eval("return {KEYS[1],ARGV[1]}", []string{"key"}, []string{"hello"}).Result()
