A high-performance, header-only C++ library for binding to Lua with advanced features and zero-overhead abstractions.
sol2 is a C++ library that provides bindings between C++ and Lua, enabling seamless integration of Lua scripting into C++ applications. It solves the problem of exposing C++ types, functions, and objects to Lua with high performance and minimal overhead, abstracting away the low-level Lua C API.
C++ developers who need to embed Lua scripting in their applications, such as game developers, tools programmers, and software engineers building extensible systems.
Developers choose sol2 for its benchmark-leading performance, header-only simplicity, comprehensive C++ type support, and modern C++17 features, making it the most efficient and easy-to-use Lua binding library available.
Sol3 (sol2 v3.0) - a C++ <-> Lua API wrapper with advanced features and top notch performance - is here, and it's great! Documentation:
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Benchmarked as the fastest C++ Lua binding library, with zero-overhead abstractions ensuring efficient script execution, as highlighted in the documentation's benchmarks.
Handles a wide range of C++ types including strings, containers, smart pointers, and C++17 variants, making integration seamless for complex data structures.
Easy drag-and-drop setup with single header files, allowing quick addition to projects without complex build systems, as emphasized in the README for ease of use.
Leverages C++17 features like variants and optionals, providing a contemporary API that aligns with modern C++ practices and enhances type safety.
Necessitates compilers supporting C++17 or later, limiting compatibility with older toolchains and projects not yet upgraded, as admitted in the README's supported compilers section.
The header-only, template-heavy design can lead to increased compile times, especially in large codebases, which might impact development speed.
Only supports Lua bindings, so projects needing integration with other scripting languages require additional libraries or alternative solutions.
