Functions

func BufferStdin

func BufferStdin() *bufio.Reader

BufferStdin is used to allow reading prompts for stdin multiple times, when we read from non-tty

func GetCheckPassword

func GetCheckPassword(prompt, prompt2 string, buf *bufio.Reader) (string, error)

GetCheckPassword will prompt for a password twice to verify they match (for creating a new password). It enforces the password length. Only parses password once if input is piped in.

func GetConfirmation

func GetConfirmation(prompt string, buf *bufio.Reader) (bool, error)

GetConfirmation will request user give the confirmation from stdin. "y", "Y", "yes", "YES", and "Yes" all count as confirmations. If the input is not recognized, it will ask again.

func GetPassword

func GetPassword(prompt string, buf *bufio.Reader) (pass string, err error)

GetPassword will prompt for a password one-time (to sign a tx) It enforces the password length

func GetSeed

func GetSeed(prompt string, buf *bufio.Reader) (string, error)

GetSeed will request a seed phrase from stdin and trims off leading/trailing spaces

func GetString

func GetString(prompt string, buf *bufio.Reader) (string, error)

GetString simply returns the trimmed string output of a given reader.

func PrintPrefixed

func PrintPrefixed(msg string)

PrintPrefixed prints a string with > prefixed for use in prompts.
