Overview

The TYPO3 Upgrade Analyzer is a comprehensive tool that evaluates TYPO3 installations externally without requiring installation into the target system. It provides objective risk measures and effort estimates through automated analysis.

Features

• Standalone Operation: Operates completely independently of target TYPO3 installation
• Cross-Version Compatibility: Works with TYPO3 versions 6.x through 13.x
• Comprehensive Analysis: Multiple analyzer types for thorough evaluation
• Multiple Output Formats: HTML and Markdown reports
• Clean Architecture: Follows clean architecture principles with strict separation of concerns
• Modular Analyzer System: Dynamic analyzer discovery with pluggable implementations
• Advanced Static Analysis: Integrates TYPO3 Rector and Fractor for code modernization analysis
• External API Integration: Checks TYPO3 Extension Repository, Packagist, and Git repositories
• Caching Support: Built-in caching for improved performance on repeated analyses

Requirements

• PHP 8.3 or higher
• Composer for dependency management
• External Tools (automatically managed via Composer):
  • ssch/typo3-rector for TYPO3-specific code analysis
  • a9f/typo3-fractor for TypoScript modernization
  • Network access for external API calls (TER, Packagist, GitHub)

Installation

Via Composer (Recommended)

# For development/local use
composer require --dev cpsit/typo3-upgrade-analyser

# For global installation
composer global require cpsit/typo3-upgrade-analyser

From Source

git clone https://github.com/cpsit/typo3-upgrade-analyser.git
cd typo3-upgrade-analyser
composer install

Quick Start

1. Create Configuration File:

   ./bin/typo3-analyzer init-config

2. Analyze TYPO3 Installation:

   ./bin/typo3-analyzer analyze

3. View Results: Check the var/reports/ directory for HTML and Markdown reports.

For detailed usage instructions, see the Usage Guide.

Available Analyzers

Currently Implemented

• Version Availability Analyzer (version_availability)

  • Checks extension compatibility across TER, Packagist, and Git repositories
  • Analyzes version constraints and upgrade paths
  • Provides risk scoring based on availability

• TYPO3 Rector Analyzer (typo3_rector)

  • Uses ssch/typo3-rector for TYPO3-specific code analysis
  • Detects deprecated API usage and required migrations
  • Provides automated refactoring suggestions

• Fractor Analyzer (fractor)

  • Uses a9f/typo3-fractor for TypoScript modernization
  • Analyzes TypoScript patterns and suggests improvements
  • Detects outdated TypoScript syntax

• Lines of Code Analyzer (lines_of_code)

  • Counts total lines of code, comments, and blank lines
  • Calculates code complexity metrics
  • Provides maintenance effort estimates

Analyzer Features

• Dynamic Discovery: All analyzers are automatically discovered and registered
• Caching Support: Results are cached to improve performance on repeated runs
• Configurable: Each analyzer can be enabled/disabled and configured independently
• Extensible: New analyzers can be added by implementing AnalyzerInterface

Output Structure

The analyzer creates a comprehensive output structure in the configured output directory:

  • Required migrations and refactoring opportunities
  • Risk scores and upgrade recommendations

Development

Requirements

• PHP 8.3 or higher
• Composer for dependency management
• Git for version control

Setup

git clone https://github.com/cpsit/typo3-upgrade-analyser.git
cd typo3-upgrade-analyser
composer install
