go-hexadeca

Package hexadeca implements hexadecimal encoding and decoding, for the Go programming language. This is meant to be a better alternative to Go's built-in "hex" package.

Package hexadeca has functions for hexadecimal encoding and decoding with Go types:

  • byte (i.e., uint8),
  • uint16,
  • uint32
  • uint64
  • int64

Documention

Symbols

Package hexadeca lets you pick the 16 symbols to hexadecimal encode to and hexadecimal decode from.

Package hexadeca has built-in support for the following symbol sequences:

Name zero one two three four five six seven eight nine ten eleven twelve thirteen fourteen fifteen
Lower-Case '0' '1' '2' '3' '4' '5' '6' '7' '8' '9' 'a' 'b' 'c' 'd' 'e' 'f'
Upper-Case '0' '1' '2' '3' '4' '5' '6' '7' '8' '9' 'A' 'B' 'C' 'D' 'E' 'F'
Persian '۰' '۱' '۲' '۳' '۴' '۵' '۶' '۷' '۸' '۹' 'ی' 'ک' 'ل' 'م' 'ن' 'س'

Package hexadeca also lets you pick your own symbol sequences, using a function.

Samples

Here are some samples of hexadecimal numbers using each of the built-in symbol sequences:

Name Decimal 49,374 Decimal 19,229 Decimal 255
Lower-Case c0de 4b1d ff
Upper-Case C0DE 4B1D FF
Persian نم۰ل م۱ک۴ س'س'

Custom Symbols

Package hexadeca also lets you use your own custom symbols by using your own symbol function.

For example:

func CustomSymbol(value byte) rune {
        var table [16]rune = [16]rune{
                '𝍠', //  0
                '𝍡', //  1
                '𝍢', //  2
                '𝍣', //  3
                '𝍤', //  4
                '𝍥', //  5
                '𝍦', //  6
                '𝍧', //  7
                '𝍨', //  8
                '𝍩', //  9
                '𝍪', // 10
                '𝍫', // 11
                '𝍬', // 12
                '𝍭', // 13
                '𝍮', // 14
                '𝍯', // 15
        }

        var index int = int(value) % len(table)

        var result rune = table[index]

        return result
}

// ...

r1, r0 := hexadeca.EncodeRune(value, CustomSymbol)

Samples:

  • 𝍬𝍠𝍭𝍮
  • 𝍤𝍫𝍡𝍭
