# 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
|
||
|
||
[](https://godoc.org/sourcecode.social/reiver/go-hexadeca)
|
||
|
||
## 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), `'ا'` (alef), `'ب '` (be), `'پ '` (pe), `'ت '` (te), `'ث '` (s̱e), `'ج'` (jim).
|
||
|
||
As well as defining you own using function:
|
||
```go
|
||
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)
|
