Two managed languages will be hard to integrate, but if the library is written in C or in a language with a C ABI, is possible to call it from pretty much any language. The question is whether you would want to run it in the same address space as your editor even if you could. Clang is more stable these days, but I still see clangd crashing from time to time and it would be very annoying if it were to take down my editor every time. So in the end even if you had the option of running the language plugin within the same address space, probably you wouldn't want to. A better RPC protocol than JSON would be nice, but a standard is better than no standard.
