Chalk is PSR-4 compliant so any PSR-4 autoloader will do, just add the Chalk namespace "Chalk" and point it to the Chalk/src directory.

Usage

Quick Examples

You can copy this into a .php file and test it out.

<?php

require_once 'vendor/autoload.php';

use Chalk\Chalk;
use Chalk\Style;
use Chalk\Color;
use Chalk\BackgroundColor;

// use the style method to style the text
echo Chalk::style('This text is green', Color::GREEN) . PHP_EOL;

// convenience methods are available for colors (case insensitive)
echo Chalk::green('This text is also green') . PHP_EOL;
echo Chalk::Red('This text is red') . PHP_EOL;

// use a style object to compose styles
$style = new Style([Color::RED, BackgroundColor::GREEN, Style::UNDERLINED]);
echo Chalk::style('This text is red with green background', $style) . PHP_EOL;

// use the parse method for more advanced compositions
echo Chalk::parse('This text is {green}, {yellow}, {red}, {blue} and {something else}', [
  Color::GREEN,
  Color::YELLOW,
  Color::RED,
  Color::BLUE,
  $style
]) . PHP_EOL;

// you can nest styles
// note that the text at the end of the string is still green even after the background styling is reset
echo Chalk::Green('This text has some ' . Chalk::style('nested', BackgroundColor::WHITE) . ' styling') . PHP_EOL;

Example output:

Methods

Chalk::style(string $string, mixed $style)
Style the string by passing in either a Color/BackgroundColor/Style or a composed style object.

Chalk::parse(string $string, array $styles)
For more advanced styling use the parse method to style specific parts of the string. Use "{}" tags to target part of the string and pass in an array of styles. The styles matches the index of the found tags.

Convenience methods
If you use Chalk::{COLOR}($string) with any available color (case insensitive) it will conveniently map to Chalk::style($string, {COLOR}), eg. Chalk::Red($string) === Chalk::style($string, Color::RED)
