The uMOF library is a cross platform C++ meta system. It can be used for reflection and script binding. It's written in C++11 and require modern compiler.
The library uses premake4 as the build system. To build uMOF, in command line navigate into uMOF folder, then:
premake4 action
See premake4 documentation for full list of supported actions. The project files will be created in uMOF/build folder. After compiling the project, the library
file will be in uMOF/lib.

To use meta system you should declare method and properties of class using macros.
class Test
{
public:
Test() = default;
int func(int a, int b)
{
return a + b;
}
float func(float a, float b)
{
return a + b;
}
int null()
{
return 0;
}
void test()
{
std::cout << "test" << std::endl;
}
int getVal() const
{
return _val;
}
void setVal(int v)
{
_val = v;
}
double prop;
private:
int _val;
};
U_DECALRE_METHODS(Test)
{
U_OVERLOAD(func, Test, int, int, int),
U_OVERLOAD(func, Test, float, float, float),
U_METHOD(null),
U_METHOD(test)
};
U_PROPERTIES(Test)
{
U_PROPERTY(val, READ(getVal), WRITE(setVal))
U_PROPERTY(prop, MEMBER(prop))
}
U_DECLARE_API(Test)
Now you can use exposed api of the class.
const Api api = Api::from<Test>();
Method method = api.method(0);
Test t;
int ret;
m.call(&t, ret, {1, 2});
