sol2 VS json_struct

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.

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.

Consider sol2

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.

Here's an example: sol2

Here is link number 2 - Previous text "Sol"

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.

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"

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

I made a header only library with good performance and low memory overhead to parse JSON straight into structs, and serialize structs to JSON. How to parse into non map/object types is configurable with template functions. json_struct

json_struct for serializing directly to and from structs. Its one header only and performs on par with RapidJSON.

Hi, I wrote JsonStruct. A header only library for parsing to and from structs. So I basically had the same problem: how to add metadata. I desided for having an additional macro. This leads to make it possible to add metadata to structs that you cannot modify for instance. Also, you can deside not to add metadata for all of the member of a struct. Please check it out! https://github.com/jorgen/json\_struct

Nice page! I have written a JSON header only library that parses and serializes to structs. Would you be interested in reviewing it? Performance is ok/good and I personally think usability is good as well :) https://github.com/jorgen/json_struct
