# patch-text [![Build Status](https://travis-ci.org/bendrucker/patch-text.svg?branch=master)](https://travis-ci.org/bendrucker/patch-text)

> Make multiple changes to a block of text by providing start and end indices and replacement text


## Install

```
$ npm install --save patch-text
```


## Usage

```js
var patch = require('patch-text');
var text = 'Hello guys!'
var updated = patch(text, [
  {
    start: 0,
    end: 5,
    replacement: 'Hi'
  },
  {
    start: 7,
    end: 9,
    replacement: 'al'
  }
])
// => 'Hi gals!'
```

Your patches shouldn't overlap, but they can shrink or increase the character count and your patches will still apply to the right text. 

## API
