It works by parsing code into an abstract syntax tree (AST) and matching language features against an internal ruleset covering Python 2.0\u20132.7 and 3.0\u20133.14. The tool has no external dependencies and can run on Python 3.0 or later, even when analyzing code that uses Python 2.x syntax.\n\nThe package is designed for developers who need to know or enforce minimum version requirements for their projects. It detects a wide range of language features\u2014from basic syntax like f-strings and async/await to advanced constructs like pattern matching, type aliases, and generic classes. It integrates with CI/CD pipelines and pre-commit hooks, and supports configuration files for specifying target versions. The project is well-tested with thousands of unit and integration tests.","worth_installing":"Yes. Vermin is a mature, actively maintained tool with no external dependencies, permissive licensing, and strong test coverage. It solves a concrete problem\u2014determining minimum Python version requirements\u2014with a comprehensive ruleset and multiple integration points. Install it if you need to verify or enforce Python version compatibility in your projects."},"id":"vermin","links":{"html":"https://skillfed.io/packages/vermin","md":"https://skillfed.io/packages/vermin.md","pypi":"https://pypi.org/project/vermin/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-11-20","license_spdx":"MIT","license_treatment":"permissive","name":"vermin","python_support":"supports_current","summary":"Concurrently detect the minimum Python versions needed to run code"},"popularity":{"monthly_downloads":501234,"position":6316,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.8.0"}
