Modules, Componentization, and Transition

by Gabriel Dos Reis and Pavel Curtis

Excerpt:

We provide an analysis of constraints for a good, acceptable, and scalable module system for modern C++. This analysis is based on decades of practical experience with precompiled headers, and 40+ years of the include-file model, which has shown its limits. The paper also discusses several migration strategies. The end goal is to stimulate a technical discussion about the difficult choices we face in bringing C++’s compilation model into the era of semantics-aware developer tools, and of smart distributed and cloud build systems.
