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

Symbols

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

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' [zero], '۱' [one], '۲' [two], '۳' [three], '۴' [four], '۵' [five], '۶' [six], '۷' [seven], '۸' [eight], '۹' [nine], 'ی' (ye) [ten], 'ک' (kāf) [eleven], 'ل' (lâm) [twelve], 'م' (mim) [thirteen], 'ن' (nun) [fourteen], 'س'' (sin) [fifteen]

As well as defining you own using function:

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)

hexadecimal encode byte

To hexadecimal encode a byte use any of these:

// ...

// value==254 -> mostSignificant=='f', leastSignificant=='e'
mostSignificant, leastSignificant := hexadeca.EncodeByteUsingLowerCaseSymbols(value)

// ...

// value==254 -> mostSignificant=='F', leastSignificant=='E'
mostSignificant, leastSignificant := hexadeca.EncodeByteUsingUpperCaseSymbols(value)

Or:

import (
	"sourcecode.social/reiver/go-hexadeca"
	"sourcecode.social/reiver/go-hexadeca/symbols/rune"
)

// ...

// value==254 -> mostSignificant=='f', leastSignificant=='e'
mostSignificant, leastSignificant := hexadeca.EncodeByte(value, runesymbols.LowerCase)
