Functions

func Contains

func Contains(list []string, str string) bool

func DecodeChineseToFloat64

func DecodeChineseToFloat64(cn string) (float64, error)

DecodeToFloat64 : decode a chinese number string into Float64

func DecodeChineseToInt64

func DecodeChineseToInt64(chinese string) (int64, error)

DecodeToInt64 : decode a chinese number string into Int64

func EncodeChineseFromFloat64

func EncodeChineseFromFloat64(num float64) string

EncodeFromFloat64 : convert float64 into Chinese number 由于float64固然存在的精度问题，本函数可能不会特别精准。所以小数部分最多精确到6位。

func EncodeChineseFromInt64

func EncodeChineseFromInt64(num int64) string

EncodeFromInt64 : convert int64 into Chinese number

func Filter

func Filter(s string, filter func(r rune) bool) string

func HasEmpty

func HasEmpty(args ...string) bool

func MustDecodeChineseToFloat64

func MustDecodeChineseToFloat64(cn string) float64

MustDecodeToFloat64 : decode a chinese number string into Float64 without error

func MustDecodeChineseToInt64

func MustDecodeChineseToInt64(chinese string) int64

MustDecodeToInt64 : decode a chinese number string into Int64 without error

func NotEmpty

func NotEmpty(args ...string) bool

func Remove

func Remove(strings []string, strs ...string) []string

func Reverse

func Reverse(s string) string

func Substr

func Substr(str string, start int, stop int) (string, error)

Substr returns runes between start and stop [start, stop) regardless of the chars are ascii or utf8

func TakeOne

func TakeOne(valid, or string) string

func TakeWithPriority

func TakeWithPriority(fns ...func() string) string

func Union

func Union(first, second []string) []string
