Any tips for how to make moddable games?
As someone said, make the game data-driven is a good first step but I will say, also have some sort of way to add additional game logic. For C++ games, lua is really easy to embed the interpreter in your C++ binary, read in the files from a directory (like /mods) with the C++ filesystem api new in C++17, and it's very easy to use SoL to write an API for lua specific to your game. Many games use lua in this way and it's probably the most common mod path setup.

Script Interoperability
I've only ever done this from C++, but it's using the same lua C library, so should be durable from C as well. You can look up how sol2 or any other wrapper libraries do it.

CBN Changelog: December 3, 2022. Improved LUA support in progress!
This version relies on a Lua C++ wrapper called sol2 to hide Lua stack management from the developer, so creating new bindings can be done by adding a few lines of human-readable C++. It still has to be done manually, but at least sol2 is able to automatically figure out types of objects being bound, so it's not much different from our de-/serialization code.
- RTS programming game where you write real C++ code to control your player.

why?

Have you considered using sol2? https://github.com/ThePhD/sol2 Or if you don't want to switch over, you can at least look at their code and see how they handle this.

jluna: a new Julia <-> C++ Wrapper
It is half of a pun as I was inspired by [sol3](https://github.com/ThePhD/sol2) which is a lua <-> c++ wrapper. Sol means sun and the julia c-api prefixes all it's functions with jl, luna means moon so it is pronounced "jay luna"

A new C++ <-> Julia Wrapper: jluna
If you want to be portable I'd recommend C++ and Lua, I used those for years and it runs on everything and there's this most amazing wrapper API which was a huge inspiration
What are some alternatives?
When comparing Lua and sol2 you can also consider the following projects:
ChaiScript - Embedded Scripting Language Designed for C++
Wren - The Wren Programming Language. Wren is a small, fast, class-based concurrent scripting language.
pybind11 - Seamless operability between C++11 and Python
Duktape - Duktape - embeddable Javascript engine with a focus on portability and compact footprint
SWIG - SWIG is a software development tool that connects programs written in C and C++ with a variety of high-level programming languages.
V8 - The official mirror of the V8 Git repository
luacxx - C++11 API for creating Lua bindings
Cython - The most widely used Python to C compiler
