Transit-format (JSON/MessagePack) reader/writer in C

Transit.c is a C11 library that reads and writes data in the Transit format (JSON, JSON-Verbose, and MessagePack), fully supporting the 0.8 specification including all ground and extension types with key-based compression. It is designed for developers needing high-performance, portable data interchange in C applications, particularly those working with polyglot systems or constrained environments. Its interest lies in bringing Transit’s efficient, extensible serialization to C, enabling seamless data exchange with languages like Clojure and Java without sacrificing speed or memory control.
