# chango

A go package for running tasks concurrently and control concurreny, task completion and errors.

# Examples

- Apply a function to items of a list concurrently

```go

func main() {

	list := []int{1, 2, 3, 4, 5, 6}

	res := chango.Map(list, Square, &pkg.Options{Concurrency: 10})

	for i := range res {

		fmt.Println(i.Result.(int))

	}

}

```

- Apply a function to values recived from a channel

```go

func main() {

	list := []int{1, 2, 3, 4, 5, 6}

	in := make(chan interface{}, 10)

	for _, i := range list {

		in <- i

	}

	close(in)

	res2 := pkg.Pipe(

		pkg.Pipe(in, Cube, &pkg.Options{Concurrency: 1}), 

		Square, 

		&pkg.Options{Concurrency: 1}

	)

	for i := range res2 {

		fmt.Println(i.(int))

	}

}

```

You can combine `Pipe` do some powerful stuff. 

For example, you can do Map, Filter on the items in the channel concurrently!

NOTE: Remember to close the input channel once all items are sent, or else it will result in a deadlock.
