You define a grammar by combining predefined parser elements (Word, Literal, etc.) using Python operators, then call parse_string() to parse input text. The result is a ParseResults object that behaves like both a nested list and a dictionary, depending on how you named the matched elements.\n\nThe package emphasizes speed through regex-based optimization and faster infix operator parsing, and introduces a Whitespace context manager to control what characters are skipped and how the grammar behaves globally. It differs from pyparsing in that ParserElements are immutable\u2014calling add_parse_action() returns a new element rather than modifying the original\u2014and it removes backward-compatibility cruft. The main dependencies are mo-dots and mo-future, both lightweight utility packages.","worth_installing":"Yes, if you need a PEG parser and are comfortable with immutable ParserElement semantics. The low install friction, permissive MIT license, and lack of known vulnerabilities make it safe to try. The 290-day release gap suggests stability but not active development; use it for parsing tasks where pyparsing's API or performance is a concern, but verify performance gains match your use case before committing to a migration."},"id":"mo-parsing","links":{"html":"https://skillfed.io/packages/mo-parsing","md":"https://skillfed.io/packages/mo-parsing.md","pypi":"https://pypi.org/project/mo-parsing/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2025-10-28","license_spdx":null,"license_treatment":"permissive","name":"mo-parsing","python_support":"unspecified","summary":"Another PEG Parsing Tool"},"popularity":{"monthly_downloads":227111,"position":9186,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"8.694.25301"}
