metapp VS reflecxx

https://github.com/wqking/metapp Need to register your struct to a wrapper manually.

My recent working on libraries are focusing on solving the problems you have. metapp is a runtime reflection library, jsonpp is a simple JSON library basing on metapp. More important, the meta data built in metapp is reusable for different purpose, such as serialization, scripting, etc.

Reusable technology. The core technology is from C++ reflection library metapp developed by the same developer (wqking) of jsonpp. The technology is not unique to jsonpp, it's reusable for other purposes such as runtime reflection system, serialization, script binding, etc.

You may read Core concepts and mechanism for some basic concepts. If you wonder how it parses the mystery type char const *(*(* volatile * (&)[][8])())[], or even 10 times more complicated type, it's not magic, it uses recursive template specialization.

I haven't used the cmake_find_package generator much myself. People like it because it lets you write your cmake in a mostly conan agnostic way. If you don't care about that, I find the plain cmake generator much easier to use. You can inspect the generated conanbuildinfo.cmake file to see the targets, and call conan_basic_setup(TARGETS ). Then you link against targets that look like CONAN_PKG::boost or similar. I usually wrap conan setup in a cmake utility file like this: https://github.com/jimmyorourke/reflecxx/blob/main/test/cmake/ConanSetup.cmake

I have a library and tooling that using code generation will allow you to automatically generate serialization/deserialization to your custom binary format. It uses the visitor pattern and code generation for static reflection (eg iterating over fields of a struct). Check it out at https://github.com/jimmyorourke/reflecxx. Particularly it includes an automatic to/from json, which you could use as a starting point for how to write your own visitor.

You might be interested in a project I've put together that uses libclang to generate static reflection metadata that can then be used for generic parsing or serialization: https://github.com/jimmyorourke/reflecxx. It has examples of automatic to/from json.
