Types

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

func NewStdIO() IO

NewStdIO returns a valid IO for stdin, stdout, stderr

func NewTestIO

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

NewTestIO returns a valid IO and in, out, errout buffers for unit tests
