What is Zig?

Zig is a general-purpose programming language and toolchain designed for maintaining robust, optimal, and reusable software. Created by Andrew Kelley, Zig aims to be a better alternative to C, offering modern language features while maintaining the simplicity and performance that systems programmers need.

            🚀 Why Latest Versions Matter: Zig is rapidly evolving with significant performance improvements, new language features, and critical bug fixes in each release. The latest 0.15.2 includes major enhancements like improved cross-compilation, faster compilation times, and enhanced debugging capabilities.
        

🔥 Key Features of Zig

⚡ Simple & Fast

No hidden control flow, no hidden memory allocations, no preprocessor. Focus on debugging your application, not your language knowledge.

🔧 Comptime Magic

Compile-time code execution and lazy evaluation. Call any function at compile-time and manipulate types as values without runtime overhead.

🌐 Cross-Compilation

Built-in cross-compilation support for dozens of targets. No external dependencies needed for most platforms.

🔄 C/C++ Interop

Use Zig as a drop-in C/C++ compiler with better cross-compilation. Incrementally adopt Zig in existing codebases.

🆕 What's New in Zig 0.16.0

I/O as an Interface: All I/O now requires an Io instance, enabling threaded, evented, and async backends
Async & Cancellation: Built-in task concurrency with Futures and Groups, plus standardized cancellation across all I/O operations
New Metaprogramming Builtins: @Type replaced with targeted builtins (@Int, @Struct, @Union, @Enum, etc.) for cleaner generic code
Native Deflate Compression: Built-in deflate compression with zlib-comparable performance and simplified decompression APIs
Better Stack Traces: Safe stack unwinding across nearly all platforms with improved debug info and inline caller support
Expanded Target Support: 8+ new architectures in CI including aarch64-freebsd, loongarch64, powerpc64le, and s390x

⚠️ Breaking Change — New Package Structure

This repository uses reprepro, which is configured to keep only the latest version of each package. This means older builds are replaced when a new release ships — you cannot pin a specific version with apt install zig=0.15.2 after 0.16.0 has been published.

To let users keep a previous release installed alongside the current one, packages are now named by stability tier:

zig — meta-package, always pulls in zig-stable
zig-stable — current stable release (e.g. 0.16.0)
zig-oldstable — previous stable release (e.g. 0.15.2), installable alongside zig-stable
zig-0 — deprecated, install zig-stable instead

zig-stable and zig-oldstable register with update-alternatives so you can switch the active /usr/bin/zig at any time.

⬆️ Upgrading to 0.16.0: If you have zig-0 installed from the old package structure, you must remove it first:

apt update && apt remove zig zig-0 && apt install zig

To also install the previous stable release (0.15.2) alongside 0.16.0:

apt install zig-oldstable

Step 2: Install Zig

# Install current stable Zig
sudo apt install zig

# Optionally install the previous stable release alongside it
sudo apt install zig-oldstable

# Switch between installed versions at any time
sudo update-alternatives --config zig

# Or install nightly builds for cutting-edge features
sudo apt install zig-master
                

# Install current stable Zig
apt install zig

# Optionally install the previous stable release alongside it
apt install zig-oldstable

# Switch between installed versions at any time
update-alternatives --config zig

# Or install nightly builds for cutting-edge features
apt install zig-master
                

🎯 Basic Usage Examples

Create a new project:

# Create and enter project directory
mkdir my-zig-project && cd my-zig-project

# Initialize new Zig project
zig init

# Build and run
zig build run
        

Compile a single file:

# Create hello.zig
echo 'const std = @import("std");
pub fn main() void {
    std.debug.print("Hello, Zig!\n", .{});
}' > hello.zig

# Compile and run
zig run hello.zig
        

Use as C compiler:

# Compile C code with Zig
zig cc -o program program.c

# Cross-compile for different targets
zig cc -target x86_64-windows -o program.exe program.c
        

🚀 Why Choose debian.griffo.io?
