c++20 modules


Recommended Posts

I was trying out the new module system in c++20, I was wondering if anyone is using or planning to use this?

https://devblogs.microsoft.com/cppblog/a-tour-of-cpp-modules-in-visual-studio/

I added an example to GitHub about it -> https://github.com/xx4g/modules-example-cpp 

The modules are stored in a file with the extension .ixx


module;
#include <iostream>
export module UserCode;
namespace UserCode
{
    void notify_user_internal() {

        std::cout << "user notified -> press any key to continue" << std::endl;
        auto result = -1;
        std::cin >> result;

    }
    export void notify_user_export() {
        notify_user_internal();
    }
}

Then in main.cpp you can import it

import UserCode;
int main()
{
	UserCode::notify_user_export();
	
	return { 0 };
}
