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

Online documentation, which includes examples, can be found at: http://godoc.org/sourcecode.social/reiver/go-hexadeca

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 symbols:

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'`

Lower-Case Samples:

c0de
4b1d

Upper-Case Samples:

C0DE
4b1d

Persian Samples:

Custom Symbols

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

Samples:

𝍬𝍠𝍭𝍮
