dylib

Dynamic library loading experiment. Provides a concise way of wiring up symbol loading.

Host code:

class FooLibrary : public Library {
  public:
    FooLibrary(std::string path) : Library(path) {}
    Import(double /* return type */, bar, int /* x */)
    // Add as many Import's as you want.
};
...
FooLibrary foo("foolib.dylib");
double y = foo.bar(100);
...

Library code:

extern "C" {
  double FooLibrary__bar(int x);
}
double FooLibrary__bar(int x) {
  return 1.5 * x;
}
