Mirror Bridge Extension

Mirror Bridge is a C++ reflection-based tool that automatically generates bindings for Python, Lua, and JavaScript from C++ code, eliminating manual binding boilerplate.OverviewMirror Bridge is a library designed to simplify the process of exposing C++ code to other programming languages. Using C++26 reflection, it can automatically discover classes, methods, and fields in your C++ code and generate bindings for Python, Lua, and JavaScript without writing any manual glue code . This allows developers to write performance-critical code in C++ and seamlessly use it in higher-level languages.Key FeaturesAutomatic Binding Generation: Mirror Bridge detects C++ classes, methods, and fields and generates bindings automatically, reducing development time and errors .Multi-language Support: Supports Python, Lua, and JavaScript, enabling cross-language integration from a single C++ codebase .Zero Runtime Overhead: The generated bindings are efficient, with minimal performance cost compared to direct C++ calls .Experimental C++26 Reflection: Requires a compiler supporting C++26 reflection (e.g., Bloomberg's clang-p2996), .Interactive Playground: You can test Mirror Bridge in your browser or via Docker without installation .Usage ExampleSuppose you have a simple C++ class:CppCopyclass Vec3 {public: double x, y, z; Vec3(double x, double y, double z) : x(x), y(y), z(z) {} double dot(const Vec3& other) const { return x*other.x + y*other.y + z*other.z; }}; To generate Python bindings:BashCopy./mirror_bridge_auto src/ --module vec3 -o . After this, you can call dot() from Python directly without writing any binding code . Benchmarks show that even for frequent calls, Mirror Bridge can provide significant speedups compared to traditional Python wrappers, though the actual performance gain depends on the operation size and argument conversion overhead .BenefitsSimplifies cross-language development: No need for pybind11 or other manual binding frameworks.Reduces boilerplate: One command generates bindings for multiple languages.Improves maintainability: Changes in C++ code automatically propagate to bindings. Mirror Bridge is particularly useful for teams with large Python codebases that need to optimize performance-critical functions in C++ while maintaining seamless integration with existing scripts and tests .
