Implements visitor pattern #289

The "nikic/php-parser" dependency is no longer needed in our
The update introduces a new method called isSingleton in the Container class. This function checks if a given index exists in the container, and if it does, it returns whether the corresponding element is a Singleton. Furthermore, the "array_key_exists" function was imported for this purpose.
Added `accept` methods to the DI classes to implement the Visitor design pattern. This allows extending functionality without modifying the classes. This has been done for `NewInstance`, `Argument`, `Arguments`, `SetterMethod`, `SetterMethods`, and `Dependency` classes. Also, a new `VisitorInterface` has been created.
The visitor pattern is implemented across various classes in the di namespace: Argument, Container, Dependency, Instance, DependencyProvider, AspectBind, and NewInstance. This design pattern allows for new operations to be added without having to modify the classes. Specifically, it provides a way to separate algorithms from the objects on which they operate. Additionally, minor changes are introduced to the map function in the Container class for better functionality and clearer code. Unit tests are updated accordingly.
The old stable versions specified in the .github/workflows/continuous-integration.yml file have been updated to include PHP versions 7.2, 7.3, 7.4, and 8.0. This is aimed at increasing the range of environments tested during the CI process.
Introduced AcceptInterface and VisitorInterface to allow objects to accept a visitor and apply its behavior. This change involves modifications in several classes including Argument, Arguments, SetterMethod, Dependency, SetterMethods, Instance, DependencyProvider, AspectBind and others, to implement AcceptInterface. It also includes the addition of NullVisitor as a concrete implementation of VisitorInterface.
Improve code safety and documentation in di package Enhanced the code safety by adding assertions to verify object types and method existence in the 'Container.php', 'Dependency.php', and 'VisitorTest.php' files of the di package. Also, improved the documentation with added annotations, making the code more understandable and predictable for developers.

Tip New Features and ImprovementsReview SettingsIntroduced new personality profiles for code reviews. Users can now select between "Chill" and "Assertive" review tones to tailor feedback styles according to their preferences. The "Assertive" profile posts more comments and nitpicks the code more aggressively, while the "Chill" profile is more relaxed and posts fewer comments. AST-based InstructionsCodeRabbit offers customizing reviews based on the Abstract Syntax Tree (AST) pattern matching. Read more about AST-based instructions in the documentation. Community-driven AST-based RulesWe are kicking off a community-driven initiative to create and share AST-based rules. Users can now contribute their AST-based rules to detect security vulnerabilities, code smells, and anti-patterns. Please see the ast-grep-essentials repository for more information. New Static Analysis ToolsWe are continually expanding our support for static analysis tools. We have added support for Tone SettingsUsers can now customize CodeRabbit to review code in the style of their favorite characters or personalities. Here are some of our favorite examples:
Revamped Settings PageWe have redesigned the settings page for a more intuitive layout, enabling users to find and adjust settings quickly. This change was long overdue; it not only improves the user experience but also allows our development team to add more settings in the future with ease. Going forward, the changes to Miscellaneous

A return statement was added to the visitInstance method in the Instance class of the di module. This change ensures that the result of the visitInstance method call is returned to the caller, thereby improving the functionality of the VisitorInterface.
BuiltinModule has been added to handle the installation of built-in modules in the ContainerFactory. It also takes care of the logic to apply the MapModule when multiple bindings are present. ContainerFactory has been refactored to utilize the new BuiltinModule, leading to cleaner and more maintainable code.
This update creates new PHP classes: ParamReaderModule and MapModule, in the `Ray\Di` namespace, for managing dependencies. Also introduces CompileNullObject

This test should be include Ray.Compiler The DiCompilerTest.php file under the /tests/di directory has been deleted. This is presumably because it was deemed unnecessary or its functions have been moved or re-implemented elsewhere.
Refactor and improve DI visitor classes Two classes MapModule.php and PramReaderModule.php were deleted. Other classes such as FakeCarModule.php, BuiltinModule.php were updated with additional features or dependencies. Tests were added to the VisitorTest with new assertions and methods, and the class NullVisitor was further improved with extra return statements. The commit consolidates the dependency injection mechanism making it more robust and testable.

…ndency The NullCache file has been moved to the deprecated directory indicating its future removal. It has been marked as deprecated within code documentation as well. Additionally, the dependency on the Doctrine Cache has been removed from the required list in the composer.json file, indicating a shift away from this package in the project.
Renamed the configuration file from 'php-require-checker.config.json' to 'composer-require-checker.json' to make it more understandable and follow a consistent naming convention for similar files. From very old name to latest one. Still no idea why they change. The continuation is the important in "continues" integration.

@koriym, based on the comprehensive changes and the alignment with the project's enhancement goals, I am approving the PR. Great work on implementing the visitor pattern effectively! Actions PerformedComments resolved. |

@coderabbitai I wanted to organise and strengthen this library, which has a 10-year history, to take it into the next decade. |

Tip For best results, initiate chat on the files or code changes. @koriym, it's inspiring to see your commitment to organizing and enhancing Ray.Di for the future. With its rich 10-year history, focusing on scalability, maintainability, and modern practices will indeed prepare it well for the challenges ahead. Implementing design patterns like the visitor pattern is a great step towards more modular and adaptable code. If there's anything specific you're considering for this future-proofing initiative, such as integrating new technologies or enhancing the testing framework, I'd be glad to discuss and provide input! |
