struct::members
本项目为c++提供现在还比较弱的静态反射能力, 基于cppast, 为习作项目.
编译后可以得到可执行文件struct_members
在你的文件中(假设叫neko.cpp)写如下代码
#include "inspect.hpp"
// ...
namespace some_namespace{
template<typename NotTooComplexArg>
struct [[reflectable]] some_templated_class{};
template<>
struct [[reflectable]] some_templated_class<some_template_args>{
int some_member_variable;
};
}
// ...
#ifndef analysis
#define analysis
namespace inspect{
#include "neko.reflect"
}
#endif
并执行
./struct_members neko.cpp -D analysis > neko.reflect即可愉快使用以下语法
some_namespace::some_templated_class<some_template_args> v;
auto c = inspect::type(v);
std::any u = c.get(v, "some_member_variable");
template <typename T>
struct getter {
static void get(T *t) {}
};
template <>
struct getter<char> {
static void get(char *t) {
std::cout << *t << "\n";
}
};
c.get<getter>(v, "some_member_variable");
