LuaBridge 3.0

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, and also compatibility is provided with lua 5.2.4, 5.3.6 and 5.4.3 as well as LuaJit.


LuaBridge is usable from a compliant C++17 compiler and offers the following features:

  • MIT Licensed
  • Headers-only: No Makefile, no .cpp files, just one #include and one header file (optional) !
  • Simple, light, and nothing else needed.
  • 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.
  • Interoperable with most common c++ standard library container types.
  • Can work with both c++ exceptions and without (Works with -fno-exceptions and /EHsc-).
  • Written in a clear and easy to debug style.
