queue

-- import "github.com/anikhasibul/queue"

package queue gives you a queue group accessibility. Helps you to limit goroutines, wait for the end of the all goroutines and much more...

maxRoutines := 50
q := queue.New(maxRoutines)
defer q.Close()
for i := 0; i != 1000; i++ {
	q.Add()
	go func(c int) {
		defer q.Done()
		fmt.Println(c)
	}(i)
}
//wait for the end of the all jobs
q.Wait()
