Looking around for help with pybind11, I saw a brief flurry of activity related to it here back in Oct 2015, when Wenzel Jakob introduced it. Since then, not so much.
I'm trying to come up-to-speed with it, though I'm not a C++ programmer, so it's been a slow slog so far. Almost the first thing I tried to do has me stumped. I have a singleton class (no public constructor, C++ programmers call an instance() member function). As a Python programmer, that seems crude to me. In Python, I'd write a __new__ method and let programmers pretend they have different instances. We already have some Boost.Python wrappers for parts of our C++ libraries. The general strategy there seems to be to create a second struct which does have a constructor and a bunch of one-line member functions, then use .def(py::init<>()) That also seems crude, *and* makes me have to repeat myself. For every member function (static or otherwise) that I want to expose, not only do I have to add the necessary .def(...) call, I have to also add a silly member function to that artificial struct created to provide a public constructor. (And since they are structurally separate, I can't even use preprocessor macros to expand things.) Is there an straightforward way to wrap a singleton class using pybind11 which minimizes the amount of boilerplate I have to write? I thought I'd be able to figure out type converters, then write a few .def(...) calls, and be done with it. That's turning out not to be the case, at least not for me. I suppose if was an actual C++ programmer, I would be further along at this point.
