Zig Programming Language

Zig is a general-purpose programming language and toolchain created by Andrew Kelley in 2015, designed as a modern alternative to C with a focus on simplicity, performance, and correctness, providing manual memory management without hidden control flow, compile-time code execution through comptime, a powerful cross-compilation toolchain that can build C, C++, and Zig code for any target from any host, and no hidden allocations or exceptions, adopted by Bun which uses Zig for its core runtime, and by Uber for build infrastructure. The comptime feature enables executing arbitrary code at compile time, with comptime parameters creating generic functions and types, enabling powerful metaprogramming without a separate macro system or preprocessor, with the compiler treating compile-time and runtime code through the same language semantics. The manual memory management requires explicit allocation through allocator parameters passed to functions, with no hidden heap allocations, no garbage collector, giving developers precise control over when and how memory is allocated and freed, with the standard library providing allocators including the GeneralPurposeAllocator, the ArenaAllocator, and the FixedBufferAllocator. The cross-compilation is a first-class feature, with the ability to build for any target operating system and architecture from any host by specifying the target triple, with no need for separate cross-compilation toolchains. The error handling through error sets. The defer and errdefer for cleanup. The C interop through translate-c. The build system with build.zig. Designed by Andrew Kelley. Designed for systems programmers.
