</p>

<p align="center">This is a silly little command line tool for sexy ANSI fonts in the console. <strong>Give your cli some love.</strong></p>

## Installing

### [npm](https://www.npmjs.com/package/cfonts)

```sh
npm i cfonts -g
```

### [yarn](https://yarnpkg.com/package/cfonts)

```sh
yarn global add cfonts
```

To use it in your shell:

```sh
$ cfonts "Hello|World\!"
```

_💡  Remember to escape the `!` character with `\` in the shell_

Or use it in your project:

```js
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:

```js
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
```

### Unit tests

The package comes with a bunch of [unit tests](https://github.com/dominikwilkowski/cfonts/blob/released/nodejs/test/unit) that aim to cover 100% of the code base.
For more details about the code coverage check out [coveralls](https://coveralls.io/github/dominikwilkowski/cfonts?branch=released).

```sh
npm run test:unit
```

### Type tests

Since the code base uses [JSDocs](https://jsdoc.app/) we use [typescript](https://www.typescriptlang.org/) to test the inferred types from those comments.
Typescript [supports JSDocs](https://www.typescriptlang.org/docs/handbook/type-checking-javascript-files.html#supported-jsdoc) and we use it in our [test](https://github.com/dominikwilkowski/cfonts/blob/released/nodejs/package.json#L37).

```sh
npm run test:types
```

### Font file test

There is also a [test suite](https://github.com/dominikwilkowski/cfonts/blob/released/nodejs/test/fonttest.js) for font files.

```sh
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:

```sh
npm run test
```


## Contributing

To build the repo install dependencies via:  
_(Since we ship a `yarn.lock` file please use [`yarn`](https://yarnpkg.com/) for development.)_

```sh
yarn
```

and run the watch to continuously transpile the code.

```sh
yarn watch
```

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