[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 ``` ## Related - [string-width-cli](https://github.com/sindresorhus/string-width-cli) - CLI for this module - [string-length](https://github.com/sindresorhus/string-length) - Get the real length of a string - [widest-line](https://github.com/sindresorhus/widest-line) - Get the visual width of the widest line in a string ## License MIT © [Sindre Sorhus](https://sindresorhus.com) string-width-2.0.0/test.js000066400000000000000000000010771277070006200154570ustar00rootroot00000000000000import test from 'ava'; import m from './'; test('main', t => { t.is(m('abcde'), 5); t.is(m('古池や'), 6); t.is(m('あいうabc'), 9); t.is(m('ノード.js'), 9); t.is(m('你好'), 4); t.is(m('안녕하세요'), 10); t.is(m('A\ud83c\ude00BC'), 5, 'surrogate'); t.is(m('\u001b[31m\u001b[39m'), 0); }); test('ignores control characters', t => { t.is(m(String.fromCharCode(0)), 0); t.is(m(String.fromCharCode(31)), 0); t.is(m(String.fromCharCode(127)), 0); t.is(m(String.fromCharCode(134)), 0); t.is(m(String.fromCharCode(159)), 0); t.is(m('\u001b'), 0); });
