Subscribe methods does not return channel about redis HOT 3 OPEN

This is currently the way to use subscriptions with gosexy/redis:

rec := make(chan []string)

go func() {
    select {
    case ls = <-rec:
        t.Logf("Got: %v\n", ls)
    }
}()

go consumer.Subscribe(rec, "channel")

The problem I tried to solve was setting up the select before attempting to subscribe (subscribe is a blocking function) and that was the way that seemed right at the time. Obviously I'm no expert and I'm sure things could be better, what do you think of this? (untested).

var rec chan []string
var err error

if rec, err = consumer.SubscribeNonBlocking("channel"); err != nil {
    t.Logf("Failed: %q", err)
}

go func() {
    select {
    case ls = <-rec:
        t.Logf("Got: %v\n", ls)
    }
}()

Do you have any suggestions?

from redis.

I just started learning Go and this question appeared, because I didn't see any point in passing this channel instead of returning new instance from subscribe function. But I'm very new to Go, so I don't know how things here should be done.

Best regards, Vyacheslav

from redis.

@Termina1 Here is a simple use case : you might want to use that channel for multiple subscribers.
