Zig

Zig is a modern system language competing with C/Rust. v0.13 (2025) stabilizes the stdlib and build system. It is famous for its C toolchain capabilities (zig cc).

When to Use

• Systems Programming: OS kernels, game engines, embedded.
• Cross-Compilation: The best cross-compiler toolchain in existence.
• Drop-in C Replacement: Can compile .c files directly.

Core Concepts

Comptime

Run code at compile time. comptime { ... }.

Allocators

Memory management is explicit. You pass an Allocator to functions.

Defer

defer allocator.free(bytes) ensures cleanup.

Best Practices (2025)

Do:

• Use zig cc: To compile C/C++ projects easier than Make/CMake.
• Handle Errors: Zig uses error unions !T.
• Use GeneralPurposeAllocator: Included debug features for leaks.

Don't:

• Don't expect stability: Only use if you can tolerate breaking changes until v1.0.
