Active alternative look here

[kunitoki]

If you’re evaluating Lua/C++ binding libraries and still looking at sol2, it’s worth reassessing based on current project health and capabilities. Repo activity and issue backlog suggest low maintenance velocity.

🚀 LuaBridge3: actively evolving alternative

Actively maintained with ongoing fixes and improvements:

• Supports Lua 5.5 and Luau (not supported by sol2)
• Performance is competitive and improving, in several cases surpassing sol2
• Support for C++20 coroutines
  • co_await into Lua
  • yield back into C++
• Open to contributions, with responsive iteration cycle

🔧 Tooling advantage: tsujikiri integrates with LuaBridge3

The ecosystem goes further with automated binding generation:

• libclang-based analyzer / transformer / generator
• Comparable in spirit to Qt’s Shiboken, but generic and extensible
• Enables:
  • Automated bindings generation (luabridge3 support builtin)
  • API surface versioning with automation major / minor version bumps suggestions
  • Reduced manual glue code and maintenance cost

Hope you find this useful and can get some inspiration from it.

Hi, thanks for the detailed introduction of LuaBridge3!
I’m currently using EnTT (the C++ entity-component system) together with sol2 via entt-meets-sol2, and one thing I really rely on is EnTT’s meta system (runtime reflection for types, functions, etc.).
I wonder: does LuaBridge3 support EnTT’s meta system?
Or is there any way to expose EnTT-registered meta types/functions to Lua automatically with LuaBridge3?
Thanks in advance! 😊

Hey! No at the moment there is no direct support for EnTT meta system, but it wouldn't be difficult to add on top of what LuaBridge3 offers, pretty much like what is possible with sol2.
