Package redis was formerly a wrapper for the official redis C client hiredis. As of October 2014, package redis was splitted into two different packages: a RESP decoder (resp) and the redis client (redis) this page describes.

Build Status

How to install or upgrade

Use go get to install or upgrade (-u) the redis package.

go get -u menteslibres.net/gosexy/redis

Usage

Use import to use redis in your program:

import (
  "menteslibres.net/gosexy/redis"
)

The redis.New() function returns a *redis.Client pointer that you can use to interact with a redis server.

This example shows how to connect and ping a redis server.

var client *redis.Client

client = redis.New()

err = client.Connect(host, port)

if err != nil {
  log.Fatalf("Connect failed: %s\n", err.Error())
  return
}

log.Println("Connected to redis-server.")

log.Printf("Sending PING...\n")
s, err = client.Ping()

if err != nil {
  log.Fatalf("Could not ping: %s\n", err.Error())
  return
}

log.Printf("Received %s!\n", s)

client.Quit()

This is the expected output of the above ping-pong example:

2013/02/19 07:15:52 Connected to redis-server.
2013/02/19 07:15:52 Sending PING...
2013/02/19 07:15:52 Received PONG!

Always use client.Quit() to close the client connection.

Examples

Simple SET and GET

An example on how to use *redis.Client to send SET and GET commands to the client.

var client *redis.Client
var err error

client = redis.New()

err = client.Connect(host, port)

if err != nil {
  log.Fatalf("Connect failed: %s\n", err.Error())
  return
}

log.Println("Connected to redis-server.")

// DEL hello
log.Printf("DEL hello\n")
client.Del("hello")

// SET hello 1
log.Printf("SET hello 1\n")
client.Set("hello", 1)

// INCR hello
log.Printf("INCR hello\n")
client.Incr("hello")

// GET hello
log.Printf("GET hello\n")
s, err = client.Get("hello")

if err != nil {
  log.Fatalf("Could not GET: %s\n", err.Error())
  return
}

log.Printf("> hello = %s\n", s)

client.Quit()

This is the expected output of the above set-get example:

2013/02/19 07:19:37 Connected to redis-server.
2013/02/19 07:19:37 DEL hello
2013/02/19 07:19:37 SET hello 1
2013/02/19 07:19:37 INCR hello
2013/02/19 07:19:37 GET hello
2013/02/19 07:19:37 > hello = 2

Subscriptions

You can use SUBSCRIBE and PSUBSCRIBE with channels and goroutines inside a non-blocking connection. You can create a non-blocking connection using the ConnectNonBlock or ConnectUnixNonBlock functions.

go consumer.Subscribe(rec, "channel")

var ls []string

for {
  ls = <-rec
  log.Printf("Consumer received: %v\n", strings.Join(ls, ", "))
}

The above snippet is part of a subscription example, if you run the full example you'll see something like this:

2013/02/19 07:25:33 Consumer received: message, channel, Hello world!
2013/02/19 07:25:33 Consumer received: message, channel, Do you know how to count?
2013/02/19 07:25:33 Consumer received: message, channel, 0
2013/02/19 07:25:33 Consumer received: message, channel, 1
2013/02/19 07:25:33 Consumer received: message, channel, 2
