The Ü Programming Language

Key takeaways

  • It has safe and unsafe code separation, compile-time correctness checks, powerful abstractions like RAII and templates, encapsulation, rich type system, lambdas, coroutines and many other useful features.
  • Ü is heavily inspired by C++, but doesn't have its downsides.
  • Ü compiler is based on LLVM library and thus leverages many its powers, including numerous optimizations and code generation support for many CPU architectures and operating systems.

It has safe and unsafe code separation, compile-time correctness checks, powerful abstractions like RAII and templates, encapsulation, rich type system, lambdas, coroutines and many other useful features. Ü uses RAII for memory and resources management (no GC is involved), but manual memory management may be still used in unsafe code. Ü is memory-safe and race-condition-safe, as long as no unsafe code is involved at all or as long as unsafe code is correctly written.

Ü is heavily inspired by C++, but doesn't have its downsides. Also it was influenced by Rust, but only slightly and thus is way easier to use in comparison to Rust. Any possible coincidence with design and features of other programming languages is unintentional.

Ü compiler is based on LLVM library and thus leverages many its powers, including numerous optimizations and code generation support for many CPU architectures and operating systems. Even more, there are two Ü compilers, the first one is written in C++ and the second one is mostly written in Ü itself (frontend part, backend is still LLVM).
