Cxxwrap was broken for a while there, maybe a few years? Maybe it was cxx... I forget, whichever one let you have a c++ repl. But yea I'd argue that it's a pretty common use case to embed Julia in c++. This has been possible for a long time, Julia is written in C after all, but it's hard to do meaningfully because of Julia's GC. You have to do a lot of sketchy stuff to ensure values don't get deleted as you call for them via ffi. This might surprise you but you can do this with pretty much any other languages, usually with far less RAM consumption and JIT interruptions though...

Yes, Cxx: https://github.com/JuliaInterop/Cxx.jl -- it uses Clang to generate JIT'd interop thunks, and does neat things to enable that, like cross-language type inference and inlining (in addition to the REPL).

CxxWrap is a different thing, which AFAIK has been actively maintained for > 5 years now: https://github.com/JuliaInterop/CxxWrap.jl

It is similar to Boost.Python/pybind11/nanobind: bindings are written in C++ and compiled ahead of time into a module that defines Julia entrypoints. Those entrypoints take care of signature selection, translation to/from Julia objects, and lifetime bookkeeping.
