What's New in Rector v2?

Rector has emerged as an indispensable tool for PHP developers aiming to elevate their code quality. By automating robust programming practices, Rector not only enforces coding standards but also provides a safe pathway for migrating legacy PHP projects, even from as far back as PHP 5.3, to the latest PHP 8.4. Integrating Rector into your Continuous Integration (CI) pipeline is a smart move, enabling continuous code refinement and ensuring consistently high code quality across your projects.

The latest iteration, Rector v2, has arrived, and while performance enhancements were a primary focus, resulting in an impressive 10-15% speed boost, the dedicated team has also packed in some valuable new features. This release underscores Rector's commitment to making PHP refactoring more efficient and developer-friendly.

What's New in Rector v2?

Rector v2 isn't just about speed; it introduces features designed to give you more control and flexibility in your code refactoring workflows:

• Precision Refactoring with the --only Option: Need to target a specific coding rule? The new --only option allows you to run just one Rector rule. This is incredibly useful for focused refactoring, debugging, or when you want to apply changes incrementally.

  Example: Imagine you want to specifically address long method chains in your codebase. You can now run:

  Bash

  vendor/bin/rector --only ChainMethodCallToFluidCallRector
  

  This command will execute only the ChainMethodCallToFluidCallRector, streamlining the process and saving you time when dealing with particular code issues.

• Composer-Based Sets for Rule Management: Rector v2 embraces Composer for managing rule sets. This update simplifies the inclusion and sharing of Rector rule configurations across projects. By leveraging Composer, you can easily define and reuse sets of rules, ensuring consistency and reducing configuration overhead.

• Polyfill Packages Included by Default: Rector v2 now includes polyfill packages out-of-the-box. This is a significant enhancement for projects targeting multiple PHP versions, as Rector can automatically add necessary polyfills to ensure backward compatibility, simplifying the migration process.

• Smarter Handling of Annotations to Attributes Sets: For those leveraging PHP 8 attributes, Rector v2 brings smarter handling of annotations when converting them to attributes. This feature ensures a smoother transition to modern PHP syntax, maintaining code clarity and reducing manual adjustments.

• Leaner and More Efficient Custom Rules: If you're crafting custom Rector rules, version 2 makes the process leaner. This improvement leads to more efficient rule execution and easier maintenance of your custom refactoring logic. For developers who extend Rector's functionality, this update is a welcome enhancement.

Upgrading to Rector v2

Migrating to Rector v2 from previous versions should be a smooth experience. However, if you've written custom rules, it's recommended to consult the official upgrade guide to ensure compatibility and take advantage of the new features optimally.
