A golang implementation of the [left-pad javascript library](https://www.npmjs.com/package/left-pad)
|
||||
|
||||
I was inspired by [Stew](https://twitter.com/StewOConnor)'s [`left-cats`](https://github.com/stew/left-cats), who was inspired by [this article](http://arstechnica.com/information-technology/2016/03/rage-quit-coder-unpublished-17-lines-of-javascript-and-broke-the-internet/), to port this to Go.
|
||||
|
||||
This implementation will let you pad byte-strings and UTF-8 encoded strings
|
||||
|
||||
example usage:
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
|
||||
"github.com/willf/pad"
|
||||
padUtf8 "github.com/willf/pad/utf8"
|
||||
)
|
||||
|
||||
func main() {
|
||||
fmt.Println(pad.Right("Hello", 20, "!"))
|
||||
fmt.Println(padUtf8.Left("Exit now", 20, "→"))
|
||||
}

```

```bash
