[boost.python] def_readwrite need a default docstring

[qiaozhiqiang@…]

the default docstring defined by def_readwrite is null, can boost.python add the type name of my_s::a as the default docstring? like the function's "C++ signature" docstring.

struct my_s {

int a;

};

void export_module {

class_<my_s > s_class("my_s", init< >()); s_class.def_readwrite("a", &my_s::a); doc is empty, can boost.python add the type name of my_s::a as the default docstring? like the function's "C++ signature" docstring.

}

I do this like this: get type name of data member of class template<typename T, typename C> char const* MemberTypeName(T C::*) {

char const* name = typeid(T).name(); return name;

}

boost::python def_readwrite no docstring read write property #define DEF_READWRITE(n, p) \

def_readwrite((n), (p), std::string("read write property, type is ") + MemberTypeName(p)).c_str())

void export_module {

class_<my_s > s_class("my_s", init< >()); s_class.DEF_READWRITE("a", &my_s::a); replace all auto genarated def_readwrite to DEF_READWRITE.

}
