mirr

Minimally Invasive Runtime Reflection

---

Mirr aims to be a simple runtime reflection library for c++. It was written for use in the chroma engine. The API was written to be similar to the meta reflection system from the popular ECS library entt, while attempting to simplify the API, and make integration into a game engine easier.

Usage

The following is a simple example of the reflection system.

#include <mirr/mirr.h>

// We'll use this type for demonstrating usage.
struct vector
{
    float x, y, z;
    float magnitude();
};

int main()
{
    // To register a type
    mirr::register_type<vector>("vector")
            .data<&vector::x>("x") // Register our data members
            .data<&vector::y>("y")
            .data<&vector::z>("z")
            .function<&vector::magnitude>("magnitude"); // Register the magnitude function
            
    // Use the reflection system
    mirr::type type = mirr::resolve("vector");
    
    vector my_vector{};
    
    // Set a data member using the reflection system
    type.data("x").set(my_vector, 4.2f);
    
    // Call a function from its name using the reflection system
    float magnitude = type.function("magnitude").invoke(my_vector);
    
    return 0;
}
