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.

Newline characters will be normalized to \n.

Tab characters are expanded to spaces using 8-column tab stops before wrapping.

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.
