This repository only has features for dependencies scan You can use Pyupdater for better features.
A comprehensive CLI tool that reads, parses, and analyzes multiple dependency file formats commonly used in Python projects. The tool supports requirements.txt, Pipfile, and pyproject.toml files, providing unified dependency analysis with conflict detection, security vulnerability checking, license compatibility analysis, and PyPI integration.
- requirements.txt: Full pip requirements format support
- Pipfile: Native Pipfile parsing with fallback
- pyproject.toml: Poetry, PDM, and Flit formats
- Python Source: AST-based import analysis
- Security Scanning: CVE vulnerability detection via PyPI advisories
- License Analysis: License compatibility checking across dependencies
- Conflict Detection: Cross-file version conflicts
- PyPI Integration: Package validation and latest version checking
- Performance Benchmarks: Built-in performance testing suite
- Multiple Formats: JSON, Table, Simple text, HTML reports
- Colored Output: Enhanced visual feedback with status indicators
- Comprehensive Reports: Security, license, and dependency analysis
- Export Capabilities: Save results to custom log files
- CVE Database: Real-time vulnerability checking
- License Compatibility: SPDX-compliant license analysis
- Risk Assessment: Security and compliance scoring
- Advisory Integration: PyPI security advisories
