Carbon (programming language)

Carbon is an experimental programming language designed for connectiveness with C++. The project is open-source and was started at Google. Google engineer Chandler Carruth first introduced Carbon at the CppNorth conference in Toronto in July 2022. He stated that Carbon was created to be a C++ successor. The language is expected to have an experimental MVP version 0.1 in 2025 and a production-ready version 1.0 after 2027.

The language intends to fix several perceived shortcomings of C++ but otherwise provides a similar feature set. The main goals of the language are readability and "bi-directional interoperability" (which allows the user to include C++ code in the Carbon file), as opposed to using a new language like Rust, that, whilst being influenced by C++, is not two-way compatible with C++ programs. Changes to the language will be decided by the Carbon leads.

Carbon's documents, design, implementation, and related tools are hosted on GitHub under the Apache-2.0 license with LLVM Exceptions.
