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` 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. ## Related - [slice-ansi](https://github.com/chalk/slice-ansi) - Slice a string with ANSI escape codes - [chalk](https://github.com/chalk/chalk) - Terminal string styling done right - [jsesc](https://github.com/mathiasbynens/jsesc) - Generate ASCII-only output from Unicode strings.
