dev-lang/zig: new package
Zig is an open-source programming language designed for robustness, optimality, and maintainability. Feature Highlights - Manual memory management. Memory allocation failure is handled correctly. Edge cases matter! - Zig competes with C instead of depending on it. The Zig Standard Library does not depend on libc. - Small, simple language. Focus on debugging your application rather than debugging your knowledge of your programming language. - A fresh take on error handling that resembles what well-written C error handling looks like, minus the boilerplate and verbosity. - Debug mode optimizes for fast compilation time and crashing with a stack trace when undefined behavior would happen. - ReleaseFast mode produces heavily optimized code. What other projects call "Link Time Optimization" Zig does automatically. - ReleaseSafe mode produces optimized code but keeps safety checks enabled. Disable safety checks in the bottlenecks of your code. - Generic data structures and functions. - Compile-time reflection and compile-time code execution. No preprocessor. - Concurrency via coroutines. Async/await is thread-safe, non-blocking, and makes no syscalls, and therefore available in freestanding mode. You can multiplex coroutines onto a thread pool in userland for M:N concurrency. - Import .h files and directly use C types, variables, and functions. - Export functions, variables, and types for C code to depend on. Automatically generate .h files. - Optional type instead of null pointers. - Order independent top level declarations. - Friendly toward package maintainers. Reproducible build, 3-step bootstrapping process. - Cross-compiling is a first-class use case.
