示例1: Run
// Run runs the given command and streams all the output to the
// given UI. It also connects stdin properly so that input works as
// expected.
func Run(uiVal ui.Ui, cmd *exec.Cmd) error {
out_r, out_w := io.Pipe()
cmd.Stdin = os.Stdin
cmd.Stdout = out_w
cmd.Stderr = out_w
// Copy output to the UI until we can't.
output := false
uiDone := make(chan struct{})
go func() {
defer close(uiDone)
var buf [1024]byte
for {
n, err := out_r.Read(buf[:])
if n > 0 {
output = true
uiVal.Raw(string(buf[:n]))
}
// We just break on any error. io.EOF is not an error and
// is our true exit case, but any other error we don't really
// handle here. It probably means something went wrong
// somewhere else anyways.
if err != nil {
break
}
}
}()
// Run the command
log.Printf("[DEBUG] execDir: %s", cmd.Dir)
log.Printf("[DEBUG] exec: %s %s", cmd.Path, strings.Join(cmd.Args[1:], " "))
// Build a runnable command that we can log out to make things easier
// for debugging. This lets debuging devs just copy and paste the command.
logRunnableCommand(cmd)
// Run
err := Runner(cmd)
// Wait for all the output to finish
out_w.Close()
<-uiDone
if output {
// Output one extra newline to separate output from Otto. We only
// do this if there was any output to begin with.
uiVal.Message("")
}
// Return the output from the command
return err
