It's designed for building custom parsers when standard parsing tools (like XML or template parsers) don't fit your needs, and it includes Unicode support.\n\nThe package is production-stable according to its classifier but has been unmaintained since October 2015. It targets both Python 2.7 and Python 3.x, though the long gap since its last release raises questions about compatibility with recent Python versions. The description indicates it depends on lxml, though the exact dependency relationship is not fully documented in the fact sheet.","worth_installing":"No, unless you have a specific legacy requirement. The package is abandoned (last release 2015) with no maintenance for over 3964 days, creating risk for Python 3.10+ compatibility issues. The GPLv2 copyleft license also constrains derivative work. For new projects, consider actively maintained PEG libraries like lark or parsley instead."},"id":"pypeg2","links":{"html":"https://skillfed.io/packages/pypeg2","md":"https://skillfed.io/packages/pypeg2.md","pypi":"https://pypi.org/project/pypeg2/"},"maintenance":{"status":"abandoned"},"meta":{"latest_release":"2015-10-07","license_spdx":null,"license_treatment":"copyleft","name":"pyPEG2","python_support":"unspecified","summary":"An intrinsic PEG Parser-Interpreter for Python"},"popularity":{"monthly_downloads":83606,"position":14061,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.15.2"}
