Functions

func FromGmailFilterNames

func FromGmailFilterNames(s string) string

FromGmailFilterNames removes the " OR " separators between elements in the gmail filters sender list

func GetDomainNames

func GetDomainNames(s string) (retval string)

func GetTopLevelDomains

func GetTopLevelDomains(s string) (retval string)

func MakeSet

func MakeSet(list []string) (retval []string)

func NumSpace

func NumSpace(s string) string

NumSpace formats numeric values for readability by adding spaces every three digits.

e.g.

12345678.87654321 e-42

first, split off any exponent from the mantissa

12345678.87654321  and  e-42

next, split off any decimal part from the integer part

12345678   and    .87654321

next, add spaces between digits in the integer part

12 345 678  and    .876 543 21

finally, add any exponent back to the mantissa

func Reverse

func Reverse(s string) string

Reverse is not utf8 compatible ... focus on

utf8.DecodeRuneInString(s string) (r rune, size int)

func Reverse2

func Reverse2(s string) string

Reverse2 reverses Reference: https://stackoverflow.com/questions/1752414/how-to-reverse-a-string-in-go

func Reverse3

func Reverse3(s string) string

func Reverse5

func Reverse5(s string) string

Reverse5 returns a string with the bytes of s in reverse order.

func ReverseRune

Example

fmt.Println(input)
fmt.Println(ReverseRune(input))

Output:
