## 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.
