Cppfront: A Bold Step Toward a Simpler, Safer C++
Cppfront, an experimental front-end for the C++ programming language, aims to overhaul the language by introducing a simpler and safer syntax. Spearheaded by Herb Sutter, a leading figure in C++ development and chair of the ISO C++ committee, Cppfront seeks to modernize C++ while making it more accessible for developers. The project’s goal is ambitious: to make C++ “10x simpler, safer, and more toolable,” transforming it into a language that can evolve with modern programming needs.
The concept behind Cppfront is to create a “syntax 1 to syntax 2” compiler, which would allow developers to experiment with a new syntax while retaining compatibility with existing C++ code. This alternative syntax would introduce several transformative changes to the language. For instance, it would enable C++ to become context-free and order-independent, simplifying the learning curve and reducing the likelihood of bugs. The new syntax would also focus on making type and memory safety the default, thereby preventing some of the common pitfalls that C++ developers face today.
In addition to simplifying the language, Cppfront would also incorporate more modern features from C++ 20 and C++ 23, making modules and import std the default. By doing so, it aligns C++ with contemporary programming practices, offering a cleaner and more consistent coding experience. The new syntax would also support easier writing of parsers, refactoring tools, and other utilities, further enhancing the toolability of C++ development.
Though still in its early stages, Cppfront has been under development for several years and was publicly showcased at the CppCon conference in Aurora, CO. The compiler is compatible with major C++ 20 compilers such as MSVC, GCC, and Clang, and the project’s ongoing development can be followed on its GitHub repository. If successful, Cppfront could pave the way for a more modern, efficient, and user-friendly C++, making it a compelling option for the future of high-performance software development.
