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 does not impose any endianness for hexadecimal encoding. The individual symbols are returned separately. For example:
b1, b0 := hexadeca.EncodeByteUsingUpperCaseSymbols(u16)
b3, b2, b1, b0 := hexadeca.EncodeUint16UsingLowerCaseSymbols(u16)
r7, r6, r5, r4, r3, r2, r1, r0 := hexadeca.EncodeUint32UsingPersianSymbols(u16)
Package hexadeca has functions for hexadecimal encoding and decoding for the 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 |
'سس' |
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
