Redis client for Golang.

Usage

Example:

import "github.com/vmihailenco/redis"


connect := func() (io.ReadWriter, error) {
    fmt.Println("Connecting...")
    return net.Dial("tcp", "localhost:6379")
}

disconnect := func(conn io.ReadWriter) error {
    fmt.Println("Disconnecting...")
    conn.Close()
    return nil
}

redisClient = redis.NewClient(connect, disconnect)

_, err := redisClient.Set("foo", "bar").Reply()
if err != nil {
    panic(err)
}

value, err := redisClient.Get("foo").Reply()
if err != nil {
    if err != redis.Nil {
        panic(err)
    }
}

Multi/Exec

Getting multiClient:

multiClient := redisClient.Multi()

Or:

multiClient = redis.NewMultiClient(connect, disconnect)

Working with multiClient::

futureGet1 := multiClient.Get("foo1")
futureGet2 := multiClient.Get("foo2")
_, err := multiClient.Exec()
if err != nil {
   panic(err)
}

value1, err := futureGet1.Reply()
if err != nil {
    if err != redis.Nil {
        panic(err)
    }
}

value2, err := futureGet2.Reply()
if err != nil {
    if err != redis.Nil {
        panic(err)
    }
}

Or:

multiClient := redisClient.Multi()
multiClient.Get("foo1")
multiClient.Get("foo2")
reqs, err := multiClient.Exec()
if err != nil {
    panic(err)
}

for req := range reqs {
    value, err := req.Reply()
    if err != nil {
        if err != redis.Nil {
            panic(err)
        }
    }
}

Pub/sub

Publish:

_, err := redisClient.Publish("mychannel", "hello").Reply()
if err != nil {
    panic(err)
}

Subscribe:

pubsub := redisClient.PubSubClient()
// pubsub := redis.NewPubSubClient(connect, disconnect)

ch, err := pubsub.Subscribe("mychannel")
if err != nil {
    panic(err)
}

go func() {
    for msg := range ch {
        if msg.Err != nil {
            panic(err)
        }
        fmt.Println(msg.Message)
    }
}

Thread safety

Client is thread safe. Internally sync.Mutex is used to synchronize writes and reads.
