Is it possible to get enum name from meta::uvalue?

[MineBill]

I'm using something like this to draw a dropdown with the enum value as options:

for (auto const& evalue : enum_type.get_evalues()) {
    if (ImGui::Selectable(evalue.get_name().c_str())) {
        member.set(ptr, evalue.get_value());
    }
}

It works fine and i can set the member just fine. But I can't seem to find a way to go from a meta::uvalue (which is what member.get(ptr) returns) to a meta::evalue so i can then get the name of the enumeration. Is that possible?

Hm... It's a good feature request, because right now we can't get an evalue from dynamic values (only from static typed values). I'm going to refactor enum_type in the next few days!

Thanks for replying! I appreciate your help!
I figured out a whacky way to do this that i want to post just in case it helps someone in the future in any way:

auto GetName = [&enum_type](int i) -> std::string_view {
    for (auto const& evalue : enum_type.get_evalues()) {
        if (auto as_underlying_ptr = static_cast<int const*>(evalue.get_underlying_value().get_data()); *as_underlying_ptr == i) {
            return evalue.get_name();
        }
    }
    return std::string_view{ "Invalid" };
};

auto as_underlying_ptr = static_cast<int**>(value.get_data());
auto name = GetName(**as_underlying_ptr);

I guess this only really works because i don't specify an underlying type for my enums so it's int be default.
Also, i'm using double pointers here because the members are registered with the as_pointer policy because i need to modify them.

In any case, i'm waiting for the refactor!

So, enum_type was refactored. Now it contains value_to_evalue overloaded methods that work with static and dynamic values as well, and can be used in your case!

Here is some examples/tests of this new functionality:
