Installing

npm

npm i cfonts -g

yarn

yarn global add cfonts

To use it in your shell:

$ cfonts "Hello|World\!"

💡 Remember to escape the ! character with \ in the shell

Or use it in your project:

const cfonts = require('cfonts');

cfonts.say('Hello|world!', {
	font: 'block',              // define the font face
	align: 'left',              // define text alignment
	colors: ['system'],         // define all colors
	background: 'transparent',  // define the background color, you can also use `backgroundColor` here as key
	letterSpacing: 1,           // define letter spacing
	lineHeight: 1,              // define the line height
	space: true,                // define if the output text should have empty lines on top and on the bottom
	maxLength: '0',             // define how many character can be on one line
	gradient: false,            // define your two gradient colors
	independentGradient: false, // define if you want to recalculate the gradient for each new line
	transitionGradient: false,  // define if this is a transition between colors directly
	rawMode: false,             // define if the line breaks should be CRLF (`\r\n`) over the default LF (`\n`)
	env: 'node'                 // define the environment cfonts is being executed in
});

All settings are optional and shown here with their default

You can use cfonts in your project without the direct output to the console:

const cfonts = require('cfonts');

const prettyFont = cfonts.render('Hello|world!', {/* same settings object as above */});

prettyFont.string  // the ansi string for sexy console font
prettyFont.array   // returns the array for the output
prettyFont.lines   // returns the lines used
prettyFont.options // returns the options used

Tests

This package is tested on the below platform and node combinations as part of our CI.

Unit tests

The package comes with a bunch of unit tests that aim to cover 100% of the code base. For more details about the code coverage check out coveralls.

npm run test:unit

Type tests

Since the code base uses JSDocs we use typescript to test the inferred types from those comments. Typescript supports JSDocs and we use it in our test.

npm run test:types

Font file test

There is also a test suite for font files.

npm run test:fonts

This tool checks:

• the existence of the font
• all attributes of a font
• each character for: - existence - consistent width - consistent lines

All tests

Run all tests via:

npm run test

Contributing

To build the repo install dependencies via:
(Since we ship a yarn.lock file please use yarn for development.)

yarn

and run the watch to continuously transpile the code.

yarn watch

Please look at the coding style and work with it, not against it ;)
