README

• Install ShortCommandsBundle.

composer require yuralukashik/short-commands-bundle

• Register a folder with your commands, see config.yml:

short_commands:
  directories:
    - "%kernel.root_dir%/../examples"

• Create a PHP file, for example examples/example:use-filesystem-service.php. Name of the file example:use-filesystem-service is going to be the name of the command.
• Return a function from that file with all dependencies as arguments:

<?php

use Symfony\Component\Filesystem\Filesystem;
use Symfony\Component\Console\Output\OutputInterface;

return function (
    Filesystem $filesystem,
    OutputInterface $output,
    string $name = 'Unknown'
) {
    $currentFileExists = $filesystem->exists(__FILE__);
    $message = $currentFileExists
        ? 'current file really exists'
        : 'current file does not exist';
    $output->writeln("Hey {$name}!");
    $output->writeln("I've just checked and {$message}");
};
