Nette Framework class reflection extension for PHPStan

Nette Framework extension for PHPStan

, _(*1)

• PHPStan
• Nette Framework

This extension provides following features:, _(*2)

• Nette\ComponentModel\Container::getComponent() knows type of the component because it reads the return type on createComponent* (this works best in presenters and controls)
• Nette\DI\Container::getByType and createInstance return type based on first parameter (Foo::class).
• Nette\Forms\Container::getValues return type based on $asArray parameter.
• Nette\ComponentModel\Component::lookup return type based on $throw parameter.
• Nette\Application\UI\Component::getPresenter return type based on $throw parameter.
• Dynamic methods of Nette\Utils\Html
• Magic Nette\Object and Nette\SmartObject properties
• Event listeners through the on* properties
• Defines early terminating method calls for Presenter methods to prevent Undefined variable errors
• Understand the exact array shape coming from Nette\Utils\Strings::match() and Nette\Utils\Strings::matchAll() based on pattern

It also contains these framework-specific rules (can be enabled separately):, _(*3)

• Do not extend Nette\Object, use Nette\SmartObject trait instead
• Rethrow exceptions that are always meant to be rethrown (like AbortException)
