Using smart pointer constructor #73

Open janvorisek opened 9 months ago

janvorisek commented 9 months ago

Thanks for a really useful library!

Is it possible to make addConstructor use smart pointers?

I.e., in emscripten I can do 

EMSCRIPTEN_BINDINGS(better_smart_pointers) {
    class_<C>("C")
        .smart_ptr_constructor("C", &std::make_unique<C>)
        ;
}

My cpp library works with smart pointers all the time. Now I want to utilize it in Typescript via emglue.

Is that possible?

Hey, thanks for the issue! If I remember correctly this should already be possible (see here for an example), however the library uses std::shared_ptr instead of std::unique_ptr, as multiple references to the same object may be kept in different places.

It should be easily possible to construct a shared pointer from a unique one to bind your library to TypeScript.
