Typical Workflow

• Create a branch:

git checkout -b feature/my-change

• Implement changes + focused tests
• Run composer check
• Commit:

git add .
git commit -m "feat: add XYZ analyzer"

• Push + open PR

---

Debugging

Enable bundle debug options:

doctrine_doctor:
    profiler:
        show_debug_info: true
    debug:
        enabled: true
        internal_logging: true

Note: internal_logging adds overhead; use it only when investigating issues.

---

Local Integration Test (Symfony app)

symfony new test-app
cd test-app

In the app composer.json:

{
  "repositories": [
    {
      "type": "path",
      "url": "../doctrine-doctor"
    }
  ]
}

Then:

composer require --dev ahmed-bhs/doctrine-doctor:@dev

---

Before Opening PR

• composer check passes
• docs updated when behavior/config changes
• root changelog (CHANGELOG.md) updated when relevant
