Pty is a Go package for using unix pseudo-terminals.
(Note, there is only a Linux implementation. I'd appreciate a patch for other systems!)
go get github.com/kr/pty
package main
import (
"fmt"
"github.com/kr/pty"
"io"
"os"
"os/exec"
)
func main() {
c := exec.Command("grep", "--color=auto", "bar")
f, err := pty.Start(c)
if err != nil {
panic(err)
}
go func() {
fmt.Fprintln(f, "foo")
fmt.Fprintln(f, "bar")
fmt.Fprintln(f, "baz")
f.Close()
}()
io.Copy(os.Stdout, f)
c.Wait()
}
