WebAssembly is a nice way to go for such things in future. You provide the interface, their wasm code runs in a sandbox, and your users get to write their plugins in whatever language they like.

This gets mentioned a lot but has it been used in practice? How would you pass objects and methods etc to the scripting language? Autogenerated C headers?

  To be able to use WASM-compiled languages for embedding you first need a small WASM runtime you can depend on (and things like ref types, GC etc which have been standardized only in the last couple of years). That didn't exist until recently, but now you can use https://github.com/bytecodealliance/wasm-micro-runtime/blob/main/doc/embed_wamr.md https://github.com/bytecodealliance/wasm-micro-runtime/blob/... I am not aware of anyone using this yet, but I hope to see that become common in the next few years.

Complexity of writing and building WASM is a few magnitudes higher than just writing a simple Lua script. It might make sense for building complex plugins, but for simple stuff, Lua still excels, and doesn't require much programming knowledge in many cases.
