It includes a cleanroom pure-Python implementation of libmagic that supports 263 MIME types and can act as a drop-in replacement for the Unix `file` command, but with the added capability to recursively identify files embedded within other files\u2014similar to binwalk.\n\nThe package supports parsing and semantic mapping of PDF, ZIP, JPEG/JFIF, iNES, and any format specified in a Kaitai Struct grammar. It offers multiple output formats (including an extension of the SBuD JSON format), an interactive debugger for troubleshooting file matching and parsing, and both command-line and programmatic interfaces. The package automatically patches a known issue with Kaitai Struct's auto-generated Python code on import.","worth_installing":"Yes, if you need recursive file identification and polyglot detection. The pure-Python libmagic implementation and low install friction make it accessible, and Apache 2.0 licensing poses no restrictions. However, the aging maintenance status (204 days since last release, minimal repository activity) and 14 runtime dependencies warrant caution for production use\u2014verify that the package remains stable for your specific file formats and that dependency bloat is acceptable for your use case."},"id":"polyfile-weave","links":{"html":"https://skillfed.io/packages/polyfile-weave","md":"https://skillfed.io/packages/polyfile-weave.md","pypi":"https://pypi.org/project/polyfile-weave/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2026-01-22","license_spdx":null,"license_treatment":"permissive","name":"polyfile-weave","python_support":"supports_current","summary":"A utility to recursively map the structure of a file."},"popularity":{"monthly_downloads":935471,"position":4694,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.5.9"}
