How does Atlas help me review my Symfony `git diff`?

Atlas allows you to generate your full working diff using `Atlas: bash git diff`. You can then use Atlas's `read` tool to systematically review the output, ensuring you inspect every change across your Symfony project, from `src/Entity` to `config/services.yaml`, preventing any modifications from being overlooked before committing.

Can Atlas help me find `dd()` or `dump()` calls in my Symfony code?

Yes, Atlas can efficiently scan your Symfony codebase for debugging functions. You can use `Atlas: grep -r 'dd(' src/` or `Atlas: grep -r 'dump(' src/` to quickly locate instances of these functions within your `src/` directory, ensuring they are removed before your code reaches a reviewer or CI.

How do I run `PHPUnit (WebTestCase)` with Atlas in my Symfony project?

You can execute your `PHPUnit (WebTestCase)` tests directly through Atlas using the `bash` tool. Simply type `Atlas: bash bin/phpunit` to run your entire test suite. Atlas will display the output, allowing you to verify that all your Symfony tests pass before committing your changes.

What if I make a mistake and need to undo changes in Symfony with Atlas?

If you identify unwanted changes during your self-review, Atlas's `session revert` tool can restore your Symfony files from a previous snapshot. This command is safe, as it first asserts that the session is not busy, preventing accidental data loss and ensuring a clean rollback of your modifications.

Does Atlas integrate with `PHP-CS-Fixer` for Symfony code style?

Absolutely. Atlas allows you to run `PHP-CS-Fixer` via its `bash` tool to enforce your Symfony project's coding standards. Use `Atlas: bash vendor/bin/php-cs-fixer fix` to automatically apply formatting corrections based on your `php-cs-fixer.dist.php` configuration, ensuring consistent code style before committing.

Can Atlas help me review changes in specific Symfony configuration files?

Yes, after generating your diff, you can use `Atlas: read config/services.yaml` or `Atlas: read config/routes.yaml` to review the full content of specific Symfony configuration files. This ensures that your changes are contextually correct and align with the overall application setup, not just the isolated diff lines.

Self-review your working diff before committing in Symfony with Atlas (2026)

To catch your own mistakes in uncommitted Symfony diffs before they reach a reviewer or CI, Atlas provides a structured workflow that integrates directly with your existing Symfony toolchain, including `PHPUnit (WebTestCase)`, `Composer`, and `PHP-CS-Fixer`. By leveraging Atlas's ability to read `git` diffs, search code, and execute `bash` commands, you can thoroughly inspect changes, remove debugging artifacts, and ensure code quality in 2026.

How to Generate and Review Your Symfony Diff with Atlas

In 2026, generating and reviewing your uncommitted Symfony diff is a critical first step to self-correction. Atlas allows you to produce the working diff using `bash git diff` and then read it end to end, ensuring no changes are overlooked, even in complex Symfony bundles or service definitions.

Atlas integrates directly with your version control system, enabling you to generate a comprehensive diff of your uncommitted changes. Instead of relying on memory for files you've touched, Atlas ensures you review every modification. You can instruct Atlas to execute `bash git diff` to display the full working tree diff. Following this, Atlas's `read` tool can be used to systematically go through the output, allowing you to inspect changes across your `src/Controller`, `src/Service`, or `config/routes` files. This approach prevents isolated changes from being missed, which is especially important when refactoring Symfony services or updating Doctrine entity mappings.

How to Deep Dive into Changed Symfony Files with Atlas

Reading each changed Symfony file in full is essential to understand the impact of your modifications within its surrounding context. A raw diff only shows what changed, but Atlas helps you read the entire file, ensuring your updates to a `src/Controller` or a `config/services.yaml` are appropriate for the file's overall structure in 2026.

A standard `git diff` can obscure the broader context of your changes, potentially leading to subtle bugs or style inconsistencies. Atlas addresses this by allowing you to read each changed file in its entirety. After identifying modified files from the diff, you can use `Atlas: read src/Controller/MyController.php` or `Atlas: read config/services.yaml` to view the complete file content. This full-file review is crucial for Symfony applications, where changes in one part of a controller might affect an autowired service, or a small adjustment in a Doctrine entity mapping could have wider implications for your database schema. Atlas's ability to present the full file helps you verify that your changes align with Symfony's best practices and the existing codebase structure.

How to Scan for Debugging Artifacts in Symfony Code with Atlas

Before committing your Symfony code, it is vital to remove any debugging leftovers like temporary logging or skipped tests. Atlas provides a powerful `grep` tool to efficiently scan your working tree for common Symfony debugging functions and test annotations, ensuring a clean codebase in 2026.

Debugging functions and temporary test markers are common during development but must be removed before committing. Atlas's `grep` tool allows you to search your entire working tree for these artifacts. For Symfony applications, this includes searching for `dd()`, `dump()`, `var_dump()`, `die()`, or `exit()` calls that might have been introduced. You should also `grep` for `// @todo` comments, `SKIP` annotations in `PHPUnit (WebTestCase)` tests, or commented-out blocks of code. For example, `Atlas: grep -r 'dd(' src/` will quickly identify instances of the Symfony VarDumper component's debug function. This proactive scanning prevents accidental inclusion of debugging code that could impact performance or expose sensitive information in production.

How to Revert Unwanted Symfony Changes with Atlas Snapshots

If you discover a change that should not have been made during your self-review, Atlas offers a robust `session revert` mechanism to restore your Symfony codebase. This feature leverages snapshots to undo unwanted edits, ensuring that your working tree is clean and consistent, and it asserts the session is not busy before running in 2026.

Atlas maintains snapshots of your file changes, providing a safety net for your development workflow. If, during your review of a Symfony controller or service, you identify a modification that needs to be undone, `Atlas: session revert` can restore your files to a previous state. This is far more reliable than manually reverting changes, especially when dealing with multiple intertwined modifications across different Symfony bundles or configuration files. The `session revert` command is permission-gated and includes a crucial safety check: it refuses to run on a busy session, preventing a half-written turn from being rolled back mid-flight. This ensures data integrity and prevents accidental loss of work, making it a reliable tool for managing your Symfony codebase.

How to Validate Symfony Code with PHPUnit and PHP-CS-Fixer

Before finalizing your commit, validating your Symfony code with `PHPUnit (WebTestCase)` and `PHP-CS-Fixer` is a non-negotiable step. Atlas allows you to run these essential tools directly via `bash` commands, ensuring your code meets both functional and stylistic standards in 2026.

Running your tests and applying code formatting are crucial final checks. For Symfony projects, this means executing `PHPUnit (WebTestCase)` to verify functionality and `PHP-CS-Fixer` to enforce coding standards. Atlas enables you to run these tools direct. You can use `Atlas: bash bin/phpunit` to execute your test suite, including any `WebTestCase` tests for your controllers. After confirming all tests pass, you can then run `Atlas: bash vendor/bin/php-cs-fixer fix` to automatically correct any stylistic issues according to your project's `php-cs-fixer.dist.php` configuration. This two-step validation process, managed through Atlas, ensures that your committed Symfony code is both functionally correct and adheres to your team's coding guidelines, preventing issues from reaching CI or code review.
