Meta
A header-only, non-intrusive, macro-free runtime reflection system for C++17 and later.
What is Meta?
Meta is a header-only runtime reflection library for C++ that allows developers to inspect and manipulate types, members, and objects at runtime without macros or intrusive code changes. It solves the lack of built-in reflection in C++ by providing a lightweight, non-intrusive system for dynamic type operations, such as constructing objects, accessing data members, and invoking functions dynamically.
C++ developers working on projects that require runtime type introspection, such as game engines (e.g., EnTT integration), serialization systems, editor tools, or scripting interfaces where dynamic object handling is essential.
Developers choose Meta for its macro-free, non-intrusive design, header-only simplicity, and performance optimizations like small-buffer optimization (SBO). It offers more control and flexibility compared to other reflection libraries by avoiding allocations and supporting custom identifiers and policies.
