Functions ¶

func IsAcceptableSecretString ¶

func IsAcceptableSecretString(s string) bool

IsAcceptableSecretString returns true if s should be accepted as a secret string. The only strings that will be rejected are those that start with generatedSecretStringPrefix but don't have a matching checksum.

func NewSecretString ¶

func NewSecretString(rand io.Reader) string

NewSecretString generates a random, human readable string with a special form that includes a checksum which allows typos to be rejected (so long as the typo isn't in the first two letters).

Types ¶

type Card ¶

type Card struct {
	// contains filtered or unexported fields
}

Card represents a playing card (except for the jokers).

func ParseCard ¶

func ParseCard(s string) (card Card, ok bool)

ParseCard parses a card from a simple, two or three character string representation where the first character specifies the face value as one of "a23456789jqk" and the second the suit as one of "shdc". Case is ignored. The 10 is the exception and takes three charactors.

func (Card) IsRed ¶

func (c Card) IsRed() bool

func (Card) Number ¶

func (c Card) Number() int

func (Card) String ¶

func (c Card) String() string

String converts a Card to a two-glyph, string representation where the second glyph is a code-point for the suit.

type CardStack ¶

type CardStack struct {
	NumDecks int
	// contains filtered or unexported fields
}

func (*CardStack) Add ¶

func (cs *CardStack) Add(c Card) bool

func (*CardStack) Canonicalise ¶

func (cs *CardStack) Canonicalise() *CardStack

func (*CardStack) MinimumDecks ¶
