Functions

func CopiedBytes

func CopiedBytes(source []byte) (destination []byte)

func Debug

func Debug(format string, args ...interface{})

func Debugln

func Debugln(args ...interface{})

func ErrorIf

func ErrorIf(err error, msg string, data ...interface{})

errorIf synonymous with fatalIf but doesn't exit on error != nil

func FatalIf

func FatalIf(err error, msg string, data ...interface{})

fatalIf wrapper function which takes error and prints error messages.

func FileExists

func FileExists(path string) bool

func Filter

func Filter(xs []string, f func(string) bool) []string

func GenerateRandomId

func GenerateRandomId() []byte

func Keys

func Keys(v interface{}) []string

Get keys of a map, i.e. map[string]interface{} -> []string Note that some type checks are omitted for efficiency, you need to ensure them yourself, otherwise your program should panic

func Map

func Map(xs []string, f func(string) string) []string

func MarshalTOMLConfig

func MarshalTOMLConfig() error

func MsgPackMarshal

func MsgPackMarshal(v interface{}) ([]byte, error)

func MsgPackUnMarshal

func MsgPackUnMarshal(data []byte, v interface{}) error

func SetupConfig

func SetupConfig()

func StringInSlice

func StringInSlice(s string, ss []string) bool

func SubString

func SubString(str string, begin, length int) (substr string)

func Ternary

func Ternary(IF bool, THEN interface{}, ELSE interface{}) interface{}

mimic `?:` operator Need type assertion to convert output to expected type

func UnicodeIndex

func UnicodeIndex(str, substr string) int
