cxxopts is a lightweight, header-only C++11 library for parsing command line options in GNU style. It provides a fluent API to define options with short and long names, positional arguments, default/implicit values, and supports boolean, integer, floating-point, string, vector, optional, and filesystem types. The parser handles GNU-style syntax (e.g., --long, -a, --long=value, combined short options) and produces a ParseResult object for querying parsed values, unmatched arguments, and iteration. The library is self-contained in a single header file (include/cxxopts.hpp) and requires no external dependencies beyond the C++ standard library, with optional Unicode support via ICU. The code demonstrates careful attention to integer overflow detection, locale-independent parsing, and robust help text wrapping. It is widely used in the C++ ecosystem, with active maintenance, fuzzing, and comprehensive test coverage.
This repository is a comprehensively governed, production-grade library of 115+ prompt templates, meta-prompt generators, workshop guides, and structured routines for AI-assisted product management. It is not a deployed software application but rather a content methodology repository with application-like engineering discipline: standalone prompt contracts, coupling levels, CI-validated metadata, deterministic catalog generation, and an explicit coupling remediation plan. The library covers the full product management lifecycle—discovery, strategy, requirements, competitive intelligence, end-of-life, storytelling, and team facilitation—using three defined interaction modes (facilitation, co-construction, autonomous investigation). Notable sub-collections include an eight-discipline market intelligence framework (OSINT, FININT, GEOINT, etc.) with an all-source fusion prompt, a complete product sunset (EOL) workflow, and a TAM-SAM-SOM market sizing Langflow pipeline. The repo exhibits hybrid character: while primarily a content asset, it includes reusable Python scripts for validation and catalog generation, a GitHub Actions CI pipeline, and follows software engineering best practices such as versioning, changelogs, and architectural decision records.
