Is there any way to integrate some extensions written by C++?

[FaresX]

imgui has many useful extensions but most of them are written by C++. I wonder if I can integrate them to my own applications by some certain method. I am not familiar with C++ and the only thing I can do is to rewrite the source codes that only works for short projects. I could learn anything and wonder about the shortest path.

So in theory yes, but you'll have to create C bindings for the extension. The best way is probably to use CxxWrap.jl; for which you'll need to create a little C++ library that creates Julia-compatible C functions that call the C++ functions, and a Julia module that uses those bindings (which you can use from your ImGui program).

A more hard-core alternative would be to extend dear_bindings to work with the extensions that you want to use, and use that to create C bindings, which you can put in a JLL and call from Julia. This is similar to how the bindings for ImGui are generated, and it has the advantage that other languages could also use those bindings.

Oh, and this was just registered: https://github.com/grasph/WrapIt.jl
No idea how well it works but it might be worth trying out, especially since most imgui extensions have a relatively small API.
