Projects with multiple cpp2 files

[AdRiley]

Sorry this is a newbie question, but what is the correct way of splitting a project across multiple .cpp2 files?

Say I have this code

main: () =
{
Hello();
}

Hello : () =
{
std::cout << "Hello World";
}

And want to move the definition of Hello into a different file?

I think this is a subject of #594.

Yes I read that one, but it seems more about using headers to work alongside cpp code. What do I do in a pure ccp2 project?

[JohelEGP]

You still need Cpp2 headers, unless you're OK with forward-declaring Hello in Cpp1.

I think for pure cpp2 projects we should push towards using modules exclusively, but cppfront doesn't support that (yet) #269

I'm doing a multiple-cpp2 project right now and using Johel's modules version of cppfront. It's working pretty well. https://github.com/threeifbyair/advent2024
