type IO ¶

type IO struct {
	// In think, os.Stdin
	In io.Reader
	// Out think, os.Stdout
	Out io.Writer
	// ErrOut think, os.Stderr
	ErrOut io.Writer
}

IO provides the standard names for iostreams. This is useful for embedding and for unit testing. Inconsistent and different names make it hard to read and review code

func NewStdIO() IO

func NewTestIO() (IO, *bytes.Buffer, *bytes.Buffer, *bytes.Buffer)
