Function inIsTTY

internal/cli/provider_cmd.go:637–647

inIsTTY reports whether the supplied reader is a *os.File backed by a terminal. Tests using bytes.Buffer return false, which is what we want so the buffer-driven test path doesn't block on a confirmation prompt.

(in io.Reader)

// terminal. Tests using bytes.Buffer return false, which is what we want
// so the buffer-driven test path doesn't block on a confirmation prompt.
func inIsTTY(in io.Reader) bool {
	file, ok := in.(*os.File)
	if !ok {
		return false
	}
	info, err := file.Stat()
	if err != nil {
		return false

	return info.Mode()&os.ModeCharDevice != 0
}

// readLine reads up to a newline from in. Used only on the interactive
// confirmation path; bounded read so we don't hang on a closed stdin.
