cppfront is an experimental compiler that translates a new 'Syntax 2' (Cpp2) flavor of C++ into standard 'Syntax 1' (Cpp1) C++ code. It serves as a prototype for evolving the C++ language itself, generating output that works with existing C++20+ compilers and toolchains.

Use cases

• try an experimental cleaner C++ syntax
• prototype proposed C++ language features
• write safer simpler C++ that compiles to standard C++
• experiment with future C++ standardization ideas
• use Cpp2 alongside existing C++20 toolchains

When to choose

• you want to experiment with or give feedback on proposed C++ syntax evolution
• you want a simpler, safer 'skin' for writing ordinary C++ that interoperates with existing compilers and libraries
• you are prototyping language features for C++ standardization proposals

When to avoid

• you need a production-stable compiler for shipping software
• you want a separate successor language with its own ecosystem
• you need guaranteed long-term support or standards compliance
