Dear Jakob and all,
indeed I was blind. This works like a charm:
amount := 42
remaining := amount
ticker := time.NewTicker(5 * time.Second)
defer ticker.Stop()
for remaining > 0 {
select {
case <-ticker.C:
fmt.Printf("Progress: %d left from %d\n", remaining, amount)
case <-donChan:
remaining--
case res := <-resChan:
fmt.Println(res)
}
}
thanks all!
Chris
