Is there a way to do repetitive tasks at intervals?

Question

Is there a way to do repetitive background tasks in Go? I\'m thinking of something like Timer.schedule(task, delay, period) in Java. I know I can do this with

Answer 1

The function time.NewTicker makes a channel that sends a periodic message, and provides a way to stop it. Use it something like this (untested):

ticker := time.NewTicker(5 * time.Second)
quit := make(chan struct{})
go func() {
    for {
       select {
        case <- ticker.C:
            // do stuff
        case <- quit:
            ticker.Stop()
            return
        }
    }
 }()

You can stop the worker by closing the quit channel: close(quit).
