## API
### wrapAnsi(string, columns, options?)
Wrap words to the specified column width.
#### string
Type: `string`
A string with ANSI escape codes, like one styled by [`chalk`](https://github.com/chalk/chalk).
Newline characters will be normalized to `\n`.
#### columns
Type: `number`
The number of columns to wrap the text to.
#### options
Type: `object`
##### 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.
##### trim
Type: `boolean`\
Default: `true`
Whitespace on all lines is removed by default. Set this option to `false` if you don't want to trim.
