Herb Sutter shares his perspective on C++ evolution and provides updates on cppfront, his experimental compiler aiming for simplicity and safety.

cppnow.org linkedin.com/company/cppnow --- Keynote: The Evolution of C++ - A Typescript for Cpp - Herb Sutter - CppNow 2023 Slides: github.com/boostcon --- C++23 is done. But C++ is not! In this talk Herb will give his personal perspectives on C++’s ongoing and very active evolution, updates on his cppfront experimental compiler, and why compatibility (and what kind, and how much) is essential to continuing to bring C++ forward successfully. CHAPTERS - Intro and roadmap for the talk - 1. cppfront recap - 2. cppfront: what’s new - (a) 3 smaller new features showing simplicity+safety+efficiency - simplicity, safety and efficiency rarely in tension, with the right abstractions - chained comparisons - named loops/break/continue - main’s arguments - (b) user-defined types - explicit `this` - unified `operator=`: {construct,assign}x{copy,move} is a single function (by default) - virtual/override/final are qualifiers on `this` - DEMO: inheritance - (c) reflection and type metafunctions – DEMO: applying type metafunctions - 3. compatibility for C++ - John Carmack on compatibility in the real world - C++ from C, TypeScript from JavaScript, Swift from Objective-C, Roslyn from prior compiler - emphasizing and dissecting TypeScript’s compatibility story - Dart: similar goal, but not designed to be compatible - the “lost decade” pattern: lack of seamless compatibility will cost you a decade in adoption - three “plans”: the “10% plan”, the “Dart plan”, and the “TypeScript plan” - “10% plan”: incremental evolution-as-usual - “Dart plan”: designing something new, not worry about compatible interop, competitive - “TypeScript plan”: designing for something compatible, cooperative - filling in the blank: A TypeScript for C++ --- Herb Sutter Herb Sutter is an author and speaker, chair of the ISO C++ standards committee, and a programming language architect at Microsoft. --- think-cell develops one of the world’s leading PowerPoint applications, with C++ at the core of everything we build, from layout algorithms to deep integration with Microsoft Office.
