To use Lua scripting:
```go
client := redis.NewTCPClient(&redis.Options{
Addr: ":6379",
})
defer client.Close()
setnx := redis.NewScript(`
if redis.call("get", KEYS[1]) == false then
redis.call("set", KEYS[1], ARGV[1])
return 1
end
return 0
`)
run1 := setnx.Run(client, []string{"keynx"}, []string{"foo"})
fmt.Println(run1.Val().(int64), run1.Err())
run2 := setnx.Run(client, []string{"keynx"}, []string{"bar"})
fmt.Println(run2.Val().(int64), run2.Err())
get := client.Get("keynx")
fmt.Println(get)
// Output: 1 <nil>
// 0 <nil>
// GET keynx: foo
```
You can also write custom commands:
