jsoncpp

brew install jsoncpp v1.9.8 MIT

C++ library for parsing, generating, and manipulating JSON with optional comment preservation.

Why you might care

JsonCpp is a mature, stable library commonly used as a build dependency in C++ projects that need JSON support. It handles both serialization and deserialization, preserves comments during round-trip parsing (useful for config files), and is widely integrated into larger applications and build chains.

It can represent\nnumbers, strings, ordered sequences of values, and collections of name/value\npairs.\n\n[json-org]: http://json.org/\n\nJsonCpp is a C++ library that allows manipulating JSON values, including\nserialization and deserialization to and from strings. It can also preserve\nexisting comment in deserialization/serialization steps, making it a convenient\nformat to store user input files.\n\n## Project Status\n\nJsonCpp is a mature project in maintenance mode. Our priority is providing a stable,\nreliable JSON library for the long tail of C++ development.\n\n### Current Focus\n\n* **Security:** Addressing vulnerabilities and fuzzing results.\n* **Compatibility:** Ensuring the library builds without warnings on the latest versions of GCC,\nClang, and MSVC.\n* **Reliability:** Fixing regressions and critical logical bugs.\n\n### Out of Scope\n\n* **Performance:** We are not competing with SIMD-accelerated or reflection-based parsers.\n* **Features:** We are generally not accepting requests for new data formats or major API changes.\n\nJsonCpp remains a primary choice for developers who require comment preservation and support for\nlegacy toolchains where modern C++ standards are unavailable. The library is intended to be a\nreliable dependency that does not require frequent updates or major migration efforts.\n\n## A note on backward-compatibility\n\n* **`1.y.z` (master):** Actively mai",
