Hey there! Ready to dive into Zig, a systems programming language that’s not only powerful but also surprisingly friendly? This first chapter introduces some of the coolest things Zig has to offer.

Training your brain to think in Zig

Learning a new programming language is no walk in the park, especially when it’s a systems programming language such as Zig. You might be tempted to blame your brain, thinking it just isn’t wired to absorb all this low-level, technical stuff.

But the truth is, your brain isn’t the problem—it’s how you’re feeding it. Your brain thrives on novelty. It’s always on the lookout for something new, something interesting. That’s how it’s designed, to keep you alert and, quite literally, alive. When faced with the routine, the ordinary, or the dull, your brain tunes it out, pushing it to the background so that it can focus on what really matters.

But how does your brain decide what’s important? Imagine you’re coding away, deep in thought, and suddenly your computer starts overheating, the fans roaring like a jet engine. Your brain immediately kicks into high...

Systems programming reimagined

When you venture into the tangled mess of systems programming, it doesn’t take long before you stumble upon the usual suspects. You’ve got the classics—C and C++—those old rock bands that refuse to retire. Then, there are the hipsters, D and Odin, who are so niche that just knowing they exist feels like an insider secret. And, of course, the cool kids swell in with Rust and Go, showing off their shiny features and acting like they’ve reinvented the wheel.

But here’s the kicker—despite all this variety, none of these heavyweights entirely manage to strike that elusive balance between simplicity, transparency, and portability. That is, until Zig crashes the party, making it clear that it’s here to show everyone how it’s really done. Zig doesn’t just aim for the sweet spot; it plants its flag there and dares anyone to do better.

Language X versus language...

Maintain with Zig

One of the core principles of the Zig project is Maintain with Zig. But what does that really mean? To put it into perspective, let’s draw a parallel with two other languages that embrace a progressive approach rather than pushing for massive, disruptive rewrites: Kotlin and Carbon.

Kotlin and Carbon

Developed by JetBrains, Kotlin is a statically typed programming language that runs on the Java Virtual Machine (JVM) and can also be compiled into JavaScript or native code. Kotlin is designed to be fully interoperable with Java, which makes it a popular choice for Android development and enterprise applications.

Carbon is a language being developed by Google as a potential successor to C++. It aims to address the limitations of C++ while maintaining performance and control over low-level system resources. Carbon is designed with modern language features to improve developer productivity and code safety.

...

A new era begins

Systems programming has been stuck in the mud for too long, weighed down by the complexities of C/C++. But it doesn’t have to stay that way. The Zig project brings a fresh perspective, making systems programming more accessible, practical, and efficient. With its powerful compiler, flexible build system, a package manager on the horizon, and very simple language, Zig is set to spark a revival in the craft of low-level programming.

Luckily, you’re getting ready to be part of this change. And just between you and me, now is the perfect time to dive into Zig. Whether you’re contributing to open source projects, learning the language, or just exploring what it can do, Zig offers the tools and community support you need to succeed. As we move forward, Zig is not just helping us maintain the past—it’s building the future of systems programming.

Safety

Safety is often touted as the ultimate buzzword...

Summary

As we wrap up this chapter, you’ve now got a glimpse of what Zig brings to the table. You got the lowdown on why Zig is the go-to choice for anyone tired of the quirks and headaches of C and C++. We talked about how Zig keeps things simple and safe, without making you pull your hair out over memory bugs. You’ll find that what you learned here is the foundation for beginning to master Zig, and trust me—it’s going to make your life a lot easier.

Next up, we’re going to roll up our sleeves and get your Zig development environment up and running, ensuring you’re fully equipped to write, test, and build with Zig. This is where things get real, as we take all the theory we covered today and take the first step to produce actual code. Ready to keep the momentum going? Let’s do this!

Description

System programming has long forced developers to choose between safety and performance, but Zig changes the game with its no hidden control flow philosophy and explicit resource management. If you've struggled with memory leaks, undefined behavior, or cryptic compiler errors, Zig offers an alternative that puts you back in control. Alex Rios, a seasoned software engineer with experience building high-throughput systems across fintech, telecom, and gaming industries, brings his unconventional system design approach and offers insight into Zig, as someone who's seen the limitations of existing languages firsthand. You’ll get to grips with Zig's safety-centric design fundamentals, which will guide you through setting up your app development environment and writing your first programs. You'll then explore Zig's distinctive features in depth, such as explicit error handling, manual memory management, and compile-time execution. The book tackles each topic with a blend of technical depth and wit, ensuring you grasp not just the how but also the why behind Zig's design decisions. By the end of this book, you'll be ready to build a complete application that interacts with the OS, third-party libraries, and C dependencies, as well as engage with Zig's growing community and contribute to its ecosystem.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
