yannoff/console

A simple, lightweight console implementation for command-line PHP applications.

Latest Stable Version Total Downloads License

Why are we here ?

This library was conceived as an alternative to the symfony/console component.

Truth is, the symfony component may be good for rapid-application-development or for a proof-of-concept, but on the other hand doesn't seem to be the best option for most use-cases, since only a few among the plenty of available features are necessary.

So here came the need for the yannoff/console component.

Yet the idea was not to reinvent the wheel, but merely to provide a simpler, lighter (in size & resource) and more POSIX-compliant implementation for PHP command-line applications.

Installation

Via composer:

$ composer require yannoff/console

Usage

Here is a Hello World command example:

First the application script, the script that will be invoked using php bin/app.php

#!/usr/bin/env php
<?php
// bin/app.php

// Mute PHP deprecation warnings & notices
error_reporting(E_ERROR);

require __DIR__ . '/../vendor/autoload.php';

use Yannoff\Component\Console\Application;
use Acme\Demo\HelloCommand;

$application = new Application('acme', '0.0.0');

$application->addCommands([
    new HelloCommand('hello'),
]);

$application->run();

Then the command file:

<?php
// src/Acme/Demo/

namespace Acme\Demo;

use Yannoff\Component\Console\Command;
use Yannoff\Component\Console\Definition\Argument;
use Yannoff\Component\Console\Definition\Option;

class HelloCommand extends Command
{
    public function configure()
    {
        $this
            ->setName('hello')
            ->setHelp('Hello world')
            ->setDescription('Hello world demo application')
            ->addArgument(
                'name',
                Argument::OPTIONAL,
                'Optional name to greet'
            )
            ->addOption(
                'upper',
                'u',
                Option::FLAG,
                'Print the greetings in upper case'
            )
            ;
    }

    public function execute()
    {
        $name = $this->getArgument('name');
        $upper = $this->getOption('upper');

        $message = 'Hello ' . (null === $name ? 'World' : $name);
        if ($upper) {
            $message = strtoupper($message);
        }

        $this->write($message);

        return 0;
    }
}
