It serves as a lightweight, dependency-free alternative to python-magic/libmagic, making it suitable for cross-platform use without requiring system libraries. The package implements functions like from_file() and from_string() for basic identification, plus more detailed magic_file() and magic_stream() methods that return all possible matches ranked by confidence.\n\nSince version 2.0, puremagic includes a deep scan system that performs content-aware analysis beyond simple magic number matching, improving accuracy for formats like Office documents, text files, CSV, MP3, Python source, JSON, HDF5, email, and scientific formats. Deep scan is enabled by default but can be disabled via the PUREMAGIC_DEEPSCAN environment variable. The package also includes a command-line interface for batch file identification.","worth_installing":"Yes. Zero runtime dependencies, active maintenance, permissive MIT license, and no known vulnerabilities make this a low-risk choice. Install friction is minimal. Use it if you need file type detection without system library dependencies or if you want content-aware analysis beyond simple magic number matching. The Python 3.12+ requirement is a constraint but not a blocker for modern projects."},"id":"puremagic","links":{"html":"https://skillfed.io/packages/puremagic","md":"https://skillfed.io/packages/puremagic.md","pypi":"https://pypi.org/project/puremagic/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-04-08","license_spdx":"MIT","license_treatment":"permissive","name":"puremagic","python_support":"supports_current","summary":"Pure python implementation of magic file detection"},"popularity":{"monthly_downloads":7537817,"position":1725,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"2.2.0"}
