Functions

func CToGoString

func CToGoString(c []byte) string

func ColumnReorder

func ColumnReorder(filePath string, columns []int, delimiter string)

ColumnReorder is to reorder the CSV columns

func DetectCsvDelimiter

func DetectCsvDelimiter(filePath string) string

DetectCsvDelimiter - detect and get csv delimiter

func Equal

func Equal(a, b []string) bool

Equal :test whether the given two string slices are equal

func Find

func Find(a []string, x string) int

Find returns the smallest index i at which x == a[i], or -1 if there is no such index.

func GetColumnCount

func GetColumnCount(filePath string) int

GetColumnCount : return the CSV column count

func GetHeader

func GetHeader(filePath string) []string

GetHeader : return the CSV header

func HeaderPositionEqual

func HeaderPositionEqual(a, b []int) bool

HeaderPositionEqual :test whether the given two string slices are equal

func IsSpace

func IsSpace(b byte) bool

Test for space character

func MaxInt

func MaxInt(a, b int) int

shortcut functions. hopefully will be inlined by compiler

func MinInt

func MinInt(a, b int) int

shortcut functions. hopefully will be inlined by compiler

func RandShuffle

func RandShuffle(input []int)

RandShuffle to shuffle the given slices of numbers

func TimeTrack

func TimeTrack(start time.Time, name string)

func ToLowerByte

func ToLowerByte(b byte) byte

convert byte to lower case
