README

A production-quality Composer plugin that automatically detects and resolves dependency conflicts, with a strong focus on Drupal projects.

🎯 Features

• Programmatic Conflict Analysis: Uses Composer's internal solver to detect conflicts accurately.
• Dependency Graph Building: Maps out the relationships between conflicting packages.
• Minimal Resolution Planning: Computes the smallest set of version changes required to fix conflicts.
• Risk Assessment: Classifies the risk level of suggested changes (LOW, MEDIUM, HIGH, EXTREME).
• Drupal Integration: Specific rules for drupal/core and drupal/core-recommended.
• Dry-run and Auto-apply: See the plan or apply it automatically.

📦 Installation

composer require nmangold/composer-remedy

⚙️ Usage

When you encounter a dependency conflict, run:

composer drupal:fix-conflicts

Options

• --dry-run: Show the resolution plan without making any changes.
• --apply: Automatically execute composer require with the computed version fixes.

🛠 Architecture

The plugin follows SOLID principles and uses a service-oriented architecture:

• ConflictAnalyzer: Triggers a simulated update to capture SolverProblemsException.
• DependencyGraphBuilder: Constructs a graph of involved packages.
• ResolutionPlanner: Iteratively relaxes constraints to find a valid resolution.
• RiskAnalyzer: Evaluates the impact of version bumps.
• DrupalAnalyzer: Applies Drupal-specific logic for core and modules.

🧪 Testing

Run the test suite with PHPUnit:
