## 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`<br>
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`<br>
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.
