Rich Trott f44969a5ab tools: update ESLint to current version We have been stalled on ESLint 3.8.0 for some time. Current ESLint is 3.13.0. We have been unable to upgrade because of more aggressive reporting on some rules, including indentation. ESLint configuration options and bugfixes are now such that we can reasonably upgrade.

string-width

Get the visual width of a string - the number of columns required to display it

Some Unicode characters are fullwidth and use double the normal width. ANSI escape codes 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

const stringWidth = require('string-width');

stringWidth('古');
//=> 2

stringWidth('\u001b[1m古\u001b[22m');
//=> 2

stringWidth('a');
//=> 1
