There and Back Again: An Incremental C++ Modules Design

Log in to save this to your schedule and see who's attending!

The Clang project has been working on Modules in one form or another for many years. It started off with C and Objective-C many years ago. Today, we have a C++ compiler that can transparently use C++ Modules with existing C++ code, and we have deployed that at scale. However, this is very separate from the question of how to integrate a modular compilation model into the language itself. That is an issue that several groups working on C++ have been trying to tackle over the last few years.

Based on our experience deploying the core technology behind Modules, we have learned a tremendous amount about how they interact with existing code. This has informed the particular design we would like to see for C++ Modules, and it centers around incremental adoption. In essence, how do we take the C++ code we have today, and migrate it to directly leverage C++ Modules in its very syntax, while still interacting cleanly with C++ code that will always and forever be stuck in a legacy mode without Modules.

In this talk we will present our ideas on how C++ Modules should be designed in order to interoperate seamlessly with existing patterns, libraries, and codebases. However, these are still early days for C++ Modules. We are all still experimenting and learning about what the best design is likely to be. Here, we simply want to present a possible and still very early design direction for this feature.
