Radix is a Redis client for Go.

go get github.com/fzzy/radix/redis

To run the tests:

go get -u launchpad.net/gocheck
cd $GOROOT/src/pkg/github.com/fzzy/radix/redis
go test -v -bench=".*"

Radix has been in development for a while already. The API should hopefully now be stable enough for development.

Features implemented:

• Supports Redis 2.4.x/2.6.x.
• Pubsub support
• Pipelining support
• Simple transactions
• Asynchronous calls
• Connection pooling

Performance is decent, but has room for improvement.

Creating a Client instance is done as follows:

	import "github.com/fzzy/radix/redis"

	...

	conf := redis.DefaultConfig()
	conf.Database = 8 // Database number 
	c = redis.NewClient(conf)
	defer c.Close()

Below is an example how to call simple blocking commands. Commands can be called with the generic Call() method or with any of the shortcut methods (Set(), Get(), ...). Executing multiple commands at once (pipelining) can be done with Client.MultiCall or Client.Transaction methods. These methods return a Reply instance which contains the reply. Asynchronous call methods are prefixed with "Async" and they return a Future instance instead of a Reply.

reply := c.Set("mykey", "myvalue")
if reply.Err != nil {
	fmt.Println("redis:", reply.Err)
	return
}

s, err := c.Get("mykey").Str()
if err != nil {
	fmt.Printf("redis:", err)
	return
}

fmt.Println("mykey:", s)

Calling methods take a variadic ...interface{} as their parameter. The interface{} parameters are converted into byte strings as follows:

• s []byte -> s
• s string -> []byte(s)
• s int -> strconv.Itoa(s)
• s int8 -> strconv.FormatInt(int64(s), 10)
• s int16 -> strconv.FormatInt(int64(s), 10)
• s int32 -> strconv.FormatInt(int64(s), 10)
• s int64 -> strconv.FormatInt(s, 10)
• s uint -> strconv.FormatUint(uint64(s), 10)
• s uint8 -> strconv.FormatUint(uint64(s), 10)
• s uint16 -> strconv.FormatUint(uint64(s), 10)
• s uint32 -> strconv.FormatUint(uint64(s), 10)
• s uint64 -> strconv.FormatUint(s, 10)
• s bool -> "1", if true, otherwise "0"

Furthermore, there is special handling for slices and maps, eg.

• []int{1,2,3} is the same as giving parameters: "1", "2", "3"
• map[string]int{"foo":1, "bar":2} is the same as giving parameters: "foo", 1, "bar", 2

Other types use reflect-based default string values.
