openitemdef

A C library for parsing, validating, and manipulating Steam Inventory Schema files.

openitemdef provides a clean C API with predictable memory behavior, strict schema validation, and error reporting designed for integration into game engines, build pipelines, CLI tools, and GUI editors.
The project includes a complete test suite using Unity and optional code-coverage instrumentation via GCC/Clang.

🚧 Status

Note: This project is under active development.
