template in enigma_user

[WizzardMaker]

I am trying to use a template in the include.h file for my Extension but Enigma or LGM does not recognize my function...
Here is my code:

Code: [Select]

//include.h
#include "../../var4.h"
#include <functional>
#include <luastate.h>

namespace enigma_user{
template<typename FuncType> variant luaF_execute_file(string filepath,FuncType f);
}
Is there any way to let Enigma or LGM get the function?

No, sadly EGL doesn't allow templates or classes. That is why I'm waiting 100 years for the new parser. I even made a templated matrix extension that is in the ENIGMA repo, but cannot be enabled and used because of this. There are always a way around this though (think C instead of C++).

[WizzardMaker]

So the only way to make this happen is using #define or am I missing something?

EDIT:
Hm... I could write multiple functions to make that happen but that not really good looking

[TheExDeus]

What exactly is FuncType?

And sadly as I said, EDL is basically C. So you will have to do it the C way.
I think you can use overloads though.

[WizzardMaker]

FuncType is a Function Pointer.

[TheExDeus]

If it's just pointer, then you can use "void*". Pointers are allowed in ENIGMA and they have been working for me in the past (like passing an array to a function).

[WizzardMaker]

Yeah, I know but the problem is that I want to get GML functions that can be executed in Lua like instance_create or motion_set so I cant use void* (As I know)

[TheExDeus]

This seems to work:

Code: (edl) [Select]

void* a = instance_create;But wouldn't that mean you will be able to use only one function inside LUA?

[WizzardMaker]

Yeah, but I haven't tried your Method, I used this:

Code: [Select]

variant luaF_execute_file_int3(string filepath,const std::function<int(int, int, int)> &f);I will try it and send it in here.

Thank you.

Hm I tested it and the compiler throws this error:

I think I found a way to avoid it.
I could use a struct to get many types like this:

Code: [Select]

struct functype{
operator const std::function<int(int)>();
        ...
        ...
};And then I can use the struct functype
EDIT:
Nope that didn't work
