# buffruneio
[![Tests Status](https://travis-ci.org/pelletier/go-buffruneio.svg?branch=master)](https://travis-ci.org/pelletier/go-buffruneio)
[![GoDoc](https://godoc.org/github.com/pelletier/go-buffruneio?status.svg)](https://godoc.org/github.com/pelletier/go-buffruneio)
Buffruneio is a wrapper around bufio to provide buffered runes access with
unlimited unreads.
```go
import "github.com/pelletier/go-buffruneio"
```
## Examples
```go
import (
"fmt"
"github.com/pelletier/go-buffruneio"
"strings"
)
reader := buffruneio.NewReader(strings.NewReader("abcd"))
fmt.Println(reader.ReadRune()) // 'a'
fmt.Println(reader.ReadRune()) // 'b'
fmt.Println(reader.ReadRune()) // 'c'
reader.UnreadRune()
reader.UnreadRune()
fmt.Println(reader.ReadRune()) // 'b'
fmt.Println(reader.ReadRune()) // 'c'
```
## Documentation
The documentation and additional examples are available at
