Example: Go code for "a concurrent prime sieve":

Code: Select all

// A concurrent prime sieve
// See "Prime Numbers" section of the tutorial:
// http://golang.org/doc/go_tutorial.html
package main
// Send the sequence 2, 3, 4, ... to channel 'ch'.
func Generate(ch chan<- int) {
 for i := 2; ; i++ {
  ch <- i // Send 'i' to channel 'ch'.
 }
}
// Copy the values from channel 'in' to channel 'out',
// removing those divisible by 'prime'.
func Filter(in <-chan int, out chan<- int, prime int) {
 for {
  i := <-in // Receive value from 'in'.
  if i%prime != 0 {
   out <- i // Send 'i' to 'out'.
  }
 }
}
// The prime sieve: Daisy-chain Filter processes.
func main() {
 ch := make(chan int) // Create a new channel.
 go Generate(ch)      // Launch Generate goroutine.
 for i := 0; i < 10; i++ {
  prime := <-ch
  print(prime, "\n")
  ch1 := make(chan int)
  go Filter(ch, ch1, prime)
  ch = ch1
 }
}
