Requires a CMake-based build setup, community wrappers for Qt and Unreal Engine are maintained separately and not officially supported.
yaml-cpp is a library for C++ programs that need to read or write YAML files. YAML is a text format commonly used for configuration files, where data is organized using indentation and simple punctuation rather than XML tags or JSON brackets. This library lets C++ code load a YAML file and work with its contents as structured data, or take data from a C++ program and write it out as a properly formatted YAML file. The project follows the YAML 1.2 specification, which is the current official standard for the format. Developers integrate it into their own C++ projects using CMake, a widely used build tool that works across Windows, macOS, and Linux. The library can be built as a static library (bundled directly into the application) or as a shared library (loaded separately at runtime), depending on the needs of the project. Adding yaml-cpp to a CMake-based project can be done with CMake's FetchContent feature, which automatically downloads and links the library during the build process without requiring manual installation steps. The README points to a tutorial and a separate guide for emitting (writing out) YAML for anyone who wants to learn how to use the API. The project has a current API (version 0.5.0 and above) and an older API (version 0.3.x) that is still available but will stop receiving bug fixes in 2026. Community integrations exist for Qt and Unreal Engine, though those are maintained separately and not officially supported by this project.
