Quick threaded app with “Go”
November 19th, 2009 at 19:21Wow, seriously, hats off to Google on this one… This should make threaded apps programming easier in the future for me. They have created a language called “Go”, which in my opinion, looks like if Python and C++ had a child out of wedlock. I don’t think I’ll be able to stop gushing about Go for a while. I believe I have found my new prototyping language, however, I don’t see a reason why this couldn’t run production code…
Check out this snippet of Go code:
file: threads.go
package main
import "fmt"
import "syscall"
const THREADS = 2;
func threadtest(a int) {
fmt.Printf("Thread %d started.\n", a);
syscall.Sleep(10);
for true {
for i := 0; i < 10; i++ {
fmt.Printf("Thread %d -> %d \n", a, i);
}
}
}
func waitforever(debug int) {
for true {
if debug == 1 {
fmt.Printf(".");
} else {
fmt.Printf("");
}
}
}
func main() {
fmt.Printf("testing threads:\n");
for i := 0; i < THREADS; i++ {
go threadtest(i);
}
waitforever(0);
}
Output:
$ ./threads
testing threads:
Thread 0 started.
Thread 1 started.
Thread 0 -> 0
Thread 1 -> 0
Thread 0 -> 1
Thread 1 -> 1
Thread 0 -> 2
Thread 1 -> 2
Thread 0 -> 3
Thread 1 -> 3
Thread 0 -> 4
Thread 1 -> 4
Thread 0 -> 5
Thread 1 -> 5
Thread 0 -> 6
Thread 1 -> 6
Thread 0 -> 7
Thread 1 -> 7
Thread 0 -> 8
Thread 1 -> 8
Thread 0 -> 9
Thread 1 -> 9
