funnel

This is a library that controls the number of concurrent OS command executions.

example

const maxProcess = 1
f := funnel.New(maxProcess, context.TODO())
var wg sync.WaitGroup

for _, job := range []*funnel.Job{
	{
		Command: "ls",
		Options: []string{
			"-lh",
		},
	},
	{
		Command: "sh",
		Options: []string{
			"-c",
			"sleep 10; ls",
		},
	},
} {
	wg.Add(1)
	go func(job *funnel.Job, wg *sync.WaitGroup) {
		defer wg.Done()
		out, err := f.Request(job)
		if err != nil {
			log.Fatalln(err)
		}
		fmt.Println(out)
	}(job, &wg)
}

// wait all request completed
// this wait group is used to stop safely
f.Wg().Wait()
// wait receive
wg.Wait()
