Functions ¶
func DupReadCloser ¶
func DupReadCloser(reader io.ReadCloser) (io.ReadCloser, io.ReadCloser)

func EnterToContinue ¶
func EnterToContinue()
func ReadAndWrite ¶
func ReadTextLines ¶
func ReadTextLines(filename string, opts ...TextReadOption) ([]string, error)
func RedirectInOut ¶
func RedirectInOut() (restore func(), err error)
RedirectInOut redirects stdin to r, stdout to w, and callers need to call restore afterwards.
