LuaBridge is a lightweight and dependency-free library for mapping data, functions, and classes back and forth between C++ and Lua (a powerful, fast, lightweight, embeddable scripting language) . LuaBridge has been tested and works with Lua revisions starting from 5.1.5., although it should work in any version of Lua from 5.1.0 as well as LuaJit.
LuaBridge offers the following features:
- MIT Licensed
- A printable Reference Manual.
- Headers-only: No Makefile, no .cpp files, just one #include!
- Simple, light, and nothing else needed (like Boost).
- No macros, settings, or configuration scripts needed.
- Supports different object lifetime management models.
- Convenient, type-safe access to the Lua stack.
- Automatic function parameter type binding.
- Easy access to Lua objects like tables and functions.
- Written in a clear and easy to debug style.
Please read the LuaBridge Reference Manual for more details on the API.
Unit test build requires a CMake and C++11 compliant compiler.
There are 4 unit test flavors:
Tests51- uses Lua 5.1, with C++11 features
Tests51L- uses Lua 5.1, no C++11 features
Tests52- uses Lua 5.2, with C++11 features
Tests52L- uses Lua 5.2, no C++11 features
Build using Make on Linux/MacOS:
clone --recurse-submodules [email protected]:vinniefalco/LuaBridge.git cd LuaBridge cmake -DCMAKE_BUILD_TYPE=Debug -B build # or cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo -B build # or cmake -DCMAKE_BUILD_TYPE=Release -B build cd build make -j
Generate XCode project on MacOS:
clone --recurse-submodules [email protected]:vinniefalco/LuaBridge.git cd LuaBridge cmake -G Xcode -B build # Generates XCode project build/LuaBridge.xcodeproj
Generate MSVS solution on Windows:
clone --recurse-submodules email@example.com:vinniefalco/LuaBridge.git cd LuaBridge mkdir build cd build cmake -G "Visual Studio 15 2017 Win64" -B build # or cmake -G "Visual Studio 14 2015" -B build # or cmake -G "Visual Studio 15 2017 Win64" -B build # or cmake -G "Visual Studio 15 2017" -B build # or cmake -G "Visual Studio 15 2019" -A Win64 -B build # or cmake -G "Visual Studio 15 2019" -B build # Generates MSVS solution build/LuaBridge.sln
LuaBridge provides both a command line program and a stand-alone graphical program for compiling and running the test suite. The graphical program brings up an interactive window where you can enter execute Lua statements in a persistent environment. This application is cross platform and works on Windows, Mac OS, iOS, Android, and GNU/Linux systems with X11. The stand-alone program should work anywhere. Both of these applications include LuaBridge, Lua version 5.2, and the code necessary to produce a cross platform graphic application. They are all together in a separate repository, with no additional dependencies, available on Github at LuaBridge Demo and Tests. This is what the GUI application looks like, along with the C++ code snippet for registering the two classes:

The original version of LuaBridge was written by Nathan Reed. The project has been taken over by Vinnie Falco, who added new functionality, wrote the new documentation, and incorporated contributions from Nigel Atkinson.
