Systems Programming in Zig

This book offers a hands-on, project-driven guide to mastering systems programming with Zig.

What Sets This Book Apart Link to heading

Systems Programming in Zig immerses readers in practical systems challenges using Zig’s unique features. The book is organized into four parts with progressively challenging projects:

Part 1: The Systems Foundation Link to heading

  • Chapter 1: Standard I/O, efficient printing, file handling, buffering, environment variables, string manipulation, cross-platform paths and permission checking.
  • Chapter 2: Zig build system, unit testing with memory leak detection, coverage analysis, documentation generation and dependency management.
  • Chapter 3: Direct memory access, binary formats, extern structs, pointer arithmetic, endianness and byte casting.

Part 2: Rebuilding UNIX Tools (I/O & Filesystem) Link to heading

  • Chapter 4: Stream processing, buffered I/O, minimizing system calls and bitwise operations for data encoding.
  • Chapter 5: Directory navigation, inodes, permissions, symlinks, recursive traversal and OS-native filesystem event watching.

Part 3: Networking & Concurrency Link to heading

  • Chapter 6: TCP/UDP servers and clients, hostname resolution, concurrent servers, HTTP implementation, system monitoring and JSON handling.
  • Chapter 7: Threads, processes, daemonization, signal handling and process management.
  • Chapter 8: Concurrency patterns, mutexes, read-write locks, atomics and thread pools.
  • Chapter 9: Asynchronous I/O, event loops, non-blocking code and async/await refactoring.

Part 4: Advanced Systems Engineering Link to heading

  • Chapter 10: High-performance in-memory cache servers with custom binary protocols, state machines and LRU caches.
  • Chapter 11: SQLite3 integration using comptime reflection and generics for struct mapping.
  • Chapter 12: Domain-specific language development with lexing, parsing, ASTs and REPLs.

Readers learn not only how to write Zig, but why its approach provides a compelling alternative to C, Rust or Go.

Target Audience Link to heading

This book suits systems programmers, DevOps engineers and developers interested in low-level systems work. It requires only basic programming knowledge and no prior Zig experience. By the end, readers gain practical tools and deep understanding of systems programming.

Release Timeline Link to heading

The manuscript nears completion. Publication depends on the release of Zig 0.16.x to align with the latest stable features. Progress on Zig 0.16.x can be followed here: https://codeberg.org/ziglang/zig/milestone/32343

Further updates will cover the exact release date and purchasing options.
