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.

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
