42## API
43
44### wrapAnsi(input, columns, [options])
45
46Wrap words to the specified column width.
47
48#### input
49
50Type: `string`
51
52String with ANSI escape codes. Like one styled by [`chalk`](https://github.com/chalk/chalk).
53
54#### columns
55
56Type: `number`
57
58Number of columns to wrap the text to.
59
60#### options
61
62Type: `Object`
63
64##### hard
65
66Type: `boolean`<br>
67Default: `false`
68
69By 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.
70
71##### wordWrap
72
73Type: `boolean`<br>
74Default: `true`
75
76By 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.
77
78##### trim
79
80Type: `boolean`<br>
81Default: `true`
82
83Whitespace on all lines is removed by default. Set this option to `false` if you don't want to trim.
