Functions

func Fetch 

func Fetch(path string) string

Fetch returns a value at given key path in default locale. If key path holds an array, it returns random array element. If value looks like a regex, it attempts to regexify it.

func Letterify 

func Letterify(s string) string

Letterify replaces pattern like '??? ??' with randomly generated uppercase letters

func Numerify 

func Numerify(s string) string

Numerify replaces pattern like '##-###' with randomly generated digits.

func NumerifyAndLetterify 

func NumerifyAndLetterify(s string) string

NumerifyAndLetterify both numerifies and letterifies s.

func RandomChoice 

func RandomChoice(ss []string) string

RandomChoice returns random string from slice of strings.

func RandomInt 

func RandomInt(min, max int) int

RandomInt returns random int in [min, max] range.

func RandomInt64 

func RandomInt64(min, max int64) int64

RandomInt64 returns random int64 in [min, max] range.

func RandomRepeat 

func RandomRepeat(s string, min, max int) string

RandomRepeat returns a new string consisting of random number of copies of the string s.

func RandomString 

func RandomString(n int) string

RandomString returns a random alphanumeric string with length n.

func Regexify 

func Regexify(s string) (string, error)

Regexify attempts to generate a string that would match given regular expression. It does not handle ., *, unbounded ranges such as {1,}, extensions such as (?=), character classes, some abbreviations for character classes, and nested parentheses.

func Seed added in v1.1.0 

func Seed(seed int64)

Seed uses the provided seed value to initialize the random source to a deterministic state.
