Go implementation of [Little Endian Base 128 codec](https://en.wikipedia.org/wiki/LEB128).

## Install

```bash

$ go get -u ekyu.moe/leb128

# or better

$ dep ensure -add ekyu.moe/leb128

```

## Example

```go

package main

import (

    "fmt"

    "ekyu.moe/leb128"

)

func main() {

    // Notes: These specs are taken from https://en.wikipedia.org/wiki/LEB128

    // Encode unsigned LEB128

    fmt.Printf("%x\n", leb128.AppendUleb128(nil, 624485)) //=> e58e26

    // Encode signed LEB128

    fmt.Printf("%x\n", leb128.AppendSleb128(nil, -624485)) //=> 9bf159

    // Decode unsigned LEB128, n is the number of bytes read

    u, n := leb128.DecodeUleb128([]byte{0xe5, 0x8e, 0x26, 'a', 'b', 'c'})

    fmt.Printf("%d %d\n", u, n) //=> 624485 3

    // Decode signed LEB128, n is the number of bytes read

    s, n := leb128.DecodeSleb128([]byte{0x9b, 0xf1, 0x59, 'd', 'e', 'f'})

    fmt.Printf("%d %d\n", s, n) //=> -624485 3

}

```
