In general there isn't a concept of non-blocking IO APIs in Go. You accomplish the same thing by using goroutines.
Here's an example on Play, stdin is simulated since play doesn't allow for it.
package main
import "fmt"
import "time"
func main() {
ch := make(chan string)
go func(ch chan string) {
/* Uncomment this block to actually read from stdin
reader := bufio.NewReader(os.Stdin)
for {
s, err := reader.ReadString('
')
if err != nil { // Maybe log non io.EOF errors, if you want
close(ch)
return
}
ch <- s
}
*/
// Simulating stdin
ch <- "A line of text"
close(ch)
}(ch)
stdinloop:
for {
select {
case stdin, ok := <-ch:
if !ok {
break stdinloop
} else {
fmt.Println("Read input from stdin:", stdin)
}
case <-time.After(1 * time.Second):
// Do something when there is nothing read from stdin
}
}
fmt.Println("Done, stdin must be closed")
}
