Standardese is a documentation generator for C++ that parses source code (particularly header files) using libclang or cppast to extract code structure and documentation comments. It combines this information to produce documentation in multiple formats, including HTML, Markdown, XML, and plain text. The tool is designed to be extensible, with a modular architecture separating comment parsing, entity modeling, synopsis generation, and output generation. The project employs several software engineering patterns, such as the visitor pattern for traversing the markup DOM, a builder pattern for constructing documentation entities, and a thread pool for parallel processing. Configuration is handled via command-line options and configuration files using Boost.Program_options. The output generation system uses a generator interface that allows adding new formats without modifying the core logic. Standardese is actively maintained, with recent commits indicating ongoing development. It relies on well-established dependencies like Boost, cmark-gfm, and cppast/libclang, and its build system is based on CMake. The codebase demonstrates good craftsmanship in its separation of concerns and reusable components, such as escaping utilities and enum reflection helpers, which could be extracted for use in other projects.
