Bug Summary and Steps to Reproduce

At present, the only way to enable IntelliSense to recognize symbols in the module is through the _INTELLISENSE macro. This problem has been going on for too long. Can the official provide a future support plan! When can we truly utilize the C++20 module features.

// main.cpp
#include <iostream>

#ifdef __INTELLISENSE__
#include "test.ixx"
#endif

import test;

int main(int argc, char** argv) {
    std::cout << "hello world!" << std::endl;
    test();
    A a;
    a.f();
    a.g();

    return 0;
}

// test.ixx
export module test;

import std;

#define abc 123


export void test() {
    std::cout << "test" << std::endl;
}


export class A {
public:
    void f() {
        std::cout << "A::f()" << std::endl;
    }
    void g() {
        std::cout << "A::g()" << std::endl;
    }
};

Hi @hxznhf,

This is being tracked with issue #6302. We have been working with EDG who provides our IntelliSense parser to prioritize this, but it has taken a long time. There are some instructions in #6302 on how to get some IntelliSense support for modules if you are using the Microsoft C++ compiler and CMake (#6302 (comment)).

We will close this issue as a duplicate.
