Unfortunately rediculous feature request: c++ interop

Mentions C but I guess C++ is too weird to work with? :frowning: I wanna work
with OpenSceneGraph that is all in C++.

hi, Thanks for the suggestion re: externs. Yeah that is too much
effort. I’m going to try Felix and then Cling and then hope that Clasp
gets to a usable point soon. :wink: Or use a scheme.

I just want to make progress on the project rather than make my own
hacky tools or have to learn swig again. :-}

It will involve a bit of boilerplate, but in a pinch you can write a
wrapper that let’s the C++ be called from C. e.g:

// wrapper.h
#ifdef _cplusplus
extern "C" {
#endif

int fact2_in_cpp(int n);

#ifdef _cpplus
}
#endif

// wrapper.cpp
extern "C"
int fact2_in_cpp(int n) {
    return cpp_library::fact2(n);
}

Then you can call the wrapper from ATS.

Oh yeah, Felix … I should really give it a try someday, but really, I
just wish I could find a C or C++ oriented project to work on.

Maybe it is just my lack of perspective, but it really seems like SML style
syntax is taking off these days. The funny thing is a lot of languages that
do have such traits don’t reference (S)ML as an influencing language on
wikipedia, though Felix seems to be an exception.

It might be fun to show an interactive session log here:
