> Wordwrap a string with [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles)


## Install

```
$ npm install --save wrap-ansi
```


## Usage

```js
const chalk = require('chalk');
const wrapAnsi = require('wrap-ansi');

	'the lazy ' + chalk.green('dog and then ran away with the unicorn.');

console.log(wrapAnsi(input, 20));
```




## API

### wrapAnsi(input, columns, [options])

Wrap words to the specified column width.

#### input

Type: `string`

String with ANSI escape codes. Like one styled by [`chalk`](https://github.com/chalk/chalk).

#### columns

Type: `number`

Number of columns to wrap the text to.

#### options

##### hard

Type: `boolean`

Default: `false`

By default the wrap is soft, meaning long words may extend past the column width. Setting this to `true` will make it hard wrap at the column width.

##### wordWrap

Type: `boolean`

Default: `true`

By default, an attempt is made to split words at spaces, ensuring that they don't extend past the configured columns. If wordWrap is `false`, each column will instead be completely filled splitting words as necessary.
