+# string-width [![Build Status](https://travis-ci.org/sindresorhus/string-width.svg?branch=master)](https://travis-ci.org/sindresorhus/string-width)
+
+> Get the visual width of a string - the number of columns required to display it
+
+Some Unicode characters are [fullwidth](https://en.wikipedia.org/wiki/Halfwidth_and_fullwidth_forms) and use double the normal width. [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code) are stripped and doesn't affect the width.
+
+Useful to be able to measure the actual width of command-line output.
+
+
+## Install
+
+```
+$ npm install --save string-width
+```
+
+
+## Usage
+
+```js
+const stringWidth = require('string-width');
+
+stringWidth('古');
+//=> 2
+
+stringWidth('\u001b[1m古\u001b[22m');
+//=> 2
+
+stringWidth('a');
+//=> 1
+```

+
+> Truncate a string to a specific width in the terminal
+
+Gracefully handles [ANSI escapes](https://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles). Like a string styled with [`chalk`](https://github.com/chalk/chalk).
+
+
+## Install
+
+```
+$ npm install --save cli-truncate
+```
+
+
+## Usage
+
+```js
+const cliTruncate = require('cli-truncate');
+
+cliTruncate('unicorn', 4);
+//=> 'uni…'
+
+// Truncate at different positions
+cliTruncate('unicorn', 4, {position: 'start'});

+
+cliTruncate('unicorn', 4, {position: 'middle'});
+//=> 'un…n'
+
+cliTruncate('\u001b[31municorn\u001b[39m', 4);
+//=> '\u001b[31muni\u001b[39m…'
+
+// Truncate the paragraph to the terminal width
+const paragraph = 'Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. Aenean massa.';
+cliTruncate(paragraph, process.stdout.columns));
+//=> 'Lorem ipsum dolor sit amet, consectetuer adipiscing…'
+```
+
+
+## API
+
+### cliTruncate(input, columns, [options])
+
+#### input
+
+Type: `string`
+
+Text to truncate.
+
+#### columns
+
+Type: `number`
