Feature: #96688 - Attributes for Extbase Annotations

See Issue #96688

Description

Since PHP 8, native attributes are supported. In comparison to doc comments, attributes have auto-completion, are better readable and were “invented” for storing meta-information about properties. For more info on attributes see https://stitcher.io/blog/attributes-in-php-8 and https://www.php.net/manual/en/language.attributes.overview.php

Extbase annotations are already nearly 1:1 translatable to attributes.

Impact

In addition to their usage as annotations, the following extbase annotations have been enriched for usage as attributes:

@Extbase\ORM\Transient
@Extbase\ORM\Cascade
@Extbase\ORM\Lazy
@Extbase\IgnoreValidation
@Extbase\Validate

Examples

Transient & Lazy

Annotations:

use TYPO3\CMS\Extbase\Annotation as Extbase;

/**
 * @Extbase\ORM\Lazy()
 * @Extbase\ORM\Transient()
 */

Attribute:

use TYPO3\CMS\Extbase\Annotation as Extbase;

#[Extbase\ORM\Lazy()]
#[Extbase\ORM\Transient()]

Cascade

Annotation:

/**
 * @Extbase\ORM\Cascade("remove")
 */

Attribute:

#[Extbase\ORM\Cascade(['value' => 'remove'])]

Validate

Annotations:

/**
 * @Extbase\Validate("StringLength", options={"minimum": 1, "maximum": 10})
 * @Extbase\Validate("NotEmpty")
 * @Extbase\Validate("TYPO3.CMS.Extbase:NotEmpty")
 * @Extbase\Validate("TYPO3.CMS.Extbase.Tests.Unit.Reflection.Fixture:DummyValidator")
 * @Extbase\Validate("\TYPO3\CMS\Extbase\Validation\Validator\NotEmptyValidator")
 * @Extbase\Validate("TYPO3\CMS\Extbase\Validation\Validator\NotEmptyValidator")
 */
protected $propertyWithValidateAnnotations;

Attributes:

#[Extbase\Validate(['validator' => 'StringLength', 'options' => ['minimum' => 1, 'maximum' => 10]])]
#[Extbase\Validate(['validator' => 'NotEmpty'])]
#[Extbase\Validate(['validator' => 'TYPO3.CMS.Extbase:NotEmpty'])]
#[Extbase\Validate(['validator' => 'TYPO3.CMS.Extbase.Tests.Unit.Reflection.Fixture:DummyValidator'])]
#[Extbase\Validate(['validator' => '\TYPO3\CMS\Extbase\Validation\Validator\NotEmptyValidator'])]
#[Extbase\Validate(['validator' => NotEmptyValidator::class])]
protected $propertyWithValidateAttributes;

With promoted properties in constructor:

public function __construct(
    #[Extbase\Validate(['validator' => 'StringLength', 'options' => ['minimum' => 1, 'maximum' => 10]])]
    #[Extbase\Validate(['validator' => 'NotEmpty'])]
    #[Extbase\Validate(['validator' => 'TYPO3.CMS.Extbase:NotEmpty'])]
    #[Extbase\Validate(['validator' => 'TYPO3.CMS.Extbase.Tests.Unit.Reflection.Fixture:DummyValidator'])]
    #[Extbase\Validate(['validator' => '\TYPO3\CMS\Extbase\Validation\Validator\NotEmptyValidator'])]
    #[Extbase\Validate(['validator' => NotEmptyValidator::class])]
    public readonly string $dummyPromotedProperty
)
