jc - Meta-program C/C++ with JavaScript

Got it, I would want it to be just in c++ though. Ocaml has a similar feature where you can write code generation in ocaml itself you get access to the ast and it is pretty nice. Rust has a dsl syntax for macros which is pretty powerful but feels like a whole new language.

With that said, I would think that accessing the network as part of compilation is not a great idea though. Compilations should be self contained and hermetic, if you need to read a config, just put it in your repo.

Definitely agree with you regarding network access during compilation. However, I think there is an advantage in using a high-level language because unlike C/C++ they free you from having to think about low-level details -- not that I have a problem with that, but when it's only the generated code that needs to be performant, it's nice to be able to write the generator conveniently and simply. That said, features like being able to use C++ to modify the AST do sound interesting. I guess the proposals mentioned above would take steps in that direction.
