cli-truncate

Truncate a string to a specific width in the terminal

Gracefully handles ANSI escapes. Like a string styled with chalk.

Install

$ npm install --save cli-truncate

Usage

const cliTruncate = require('cli-truncate');

cliTruncate('unicorn', 4);
//=> 'uni…'

// Truncate at different positions
cliTruncate('unicorn', 4, {position: 'start'});
//=> '…orn'

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…'
