4 Simple Checkers for Coding Standard Haters but Clean Code Lovers

There are some checkers in coding standard world, that don't check spaces, tabs, commas nor brackets. They actually do code-review for you.

I use a set of 4 checkers to check open-source packages to help them keeping their code clean.

In Sylius they removed 500 lines of unused code just few days ago.

Among others it removed dead constructor dependencies.

It will not only make your code cleaner, but also can speed up you container build as a side effect.

4 Simple Checkers

use PhpCsFixer\Fixer\ArrayNotation\ArraySyntaxFixer;
use PhpCsFixer\Fixer\Import\NoUnusedImportsFixer;
use PhpCsFixer\Fixer\Import\OrderedImportsFixer;
use SlevomatCodingStandard\Sniffs\Classes\UnusedPrivateElementsSniff;
use Symfony\Component\DependencyInjection\Loader\Configurator\ContainerConfigurator;

return function (ContainerConfigurator $containerConfigurator): void {
    $services = $containerConfigurator->services();

    // use short array []
    $services->set(ArraySyntaxFixer::class)
        ->call('configure', [['syntax' => 'short']]);

    // drop dead code
    $services->set(UnusedPrivateElementsSniff::class);

    // drop dead use namespaces
    $services->set(NoUnusedImportsFixer::class);

    // and sort them A → Z
    $services->set(OrderedImportsFixer::class);
};

4 Steps to Make Your Code Cleaner

1. Install it

   composer require symplify/easy-coding-standard --dev
   

2. Add checkers to ecs.php file

3. Check your code

   vendor/bin/ecs check src
   

4. Fix the code

   vendor/bin/ecs check src --fix
   

Happy coding!
