Nete 3.0: Operator? is deprecated in config files

@Mabar I would not say that usage of PHP in neon is strictly “bad”. I would say there is a scale of what one may consider “useful” and what someone else may consider “I like PHP extension better”.

For those who are looking for easiest way:

Nette 2.4 code (neon config):

application.application:
	setup:
		- "$service->onError[] = ?"([@Some\Logger, logApplicationError])

As far as my knowledge goes this code does not have an equivalent in 3.0. A PHP extension may be used instead:

<?php

declare(strict_types=1);

namespace App\DI;

use Nette\Application\Application;
use Nette\DI\CompilerExtension;
use Nette\DI\Definitions\FactoryDefinition;
use Nette\DI\Definitions\ServiceDefinition;
use Nette\DI\Definitions\Statement;
use Some\Logger;

/**
 * @property-read array $config
 */
final class NativeEventsExtension extends CompilerExtension
{

	public function loadConfiguration(): void
	{
		$builder = $this->getContainerBuilder();

		$application = $builder->getByType(Application::class);

		if ($application === null) {
			throw new \UnexpectedValueException;
		}

		$applicationDefinition = $builder->getDefinition($application);

		if ($applicationDefinition instanceof ServiceDefinition) {
			/**
			 * OK
			 */
		} elseif ($applicationDefinition instanceof FactoryDefinition) {
			$applicationDefinition = $applicationDefinition->getResultDefinition();
		} else {
			throw new \UnexpectedValueException;
		}

		$builder->addDefinition($this->prefix('logger'))
			->setFactory(Logger::class);

		$applicationDefinition->addSetup(
			new Statement(
				'$service->onError[] = [?, ?]',
				['@' . Logger::class, 'logApplicationError']
			)
		);
	}
}

Do you know now why I consider the 2.4 more useful?

EDIT:

It looks there is a new syntax for 3.0:

application.application:
    setup:
        - '$service->onError[]' = [@Some\Logger, logApplicationError]

Statements with a question mark are very difficult to understand. The aim is to replace its usage with a more readable syntax.

Your example can be replaced this way

application.application:
    setup:
        - '$service->onError[]' = [@Some\Logger, logApplicationError]

@Mabar Those are there because of phpstan..

Even with max level and extensions, assert is enough
