Zig by Example Gives Systems Programmers a Practical On-Ramp

If you've been meaning to take Zig seriously, the friction just got lower. Zig by Example, written by Dariush Abbasi for Boring College, is a new open-source learning resource that teaches Zig the same way Go by Example taught a generation of Go developers: short, annotated, runnable programs that each isolate one concept.

The project landed on Hacker News' front page and has already picked up 138 stars, signaling real demand for approachable Zig documentation.

What It Covers

The curriculum is deliberately comprehensive. Starting from the basics and working toward production-adjacent topics, the example list reads like a language spec in miniature:

• Primitives & types: Values, Variables, Integers, Floats, Strings, Arrays, Slices, Vectors
• Composite types: Structs, Enums, Unions
• Control flow: If/Else, Switch, While Loops, For Loops, Blocks and Statements
• Zig-specific idioms: Defer, Errors, Optionals, Comptime, Generics
• Memory: Pointers, Multi-Pointers, Slices (Pointers), Memory Allocation, ArrayList, HashMap, Linked List
• Standard library & tooling: File I/O, Processes, JSON, Sorting, Math, Formatting and Print, Testing, Build System
• C Interop — arguably the killer feature for teams looking to escape C without rewriting everything at once

All examples target Zig 0.14, keeping the material current and avoiding the confusion that plagued older tutorials written against pre-stable releases.

Why the Format Works

Zig's core pitch — no hidden control flow, no hidden allocations, no preprocessor — is elegant on paper but demands a mental shift coming from C, C++, or even Rust. The annotated-example format is well-suited to this because it lets the language's explicitness speak for itself: you see exactly what memory is being allocated and where, exactly what error paths exist, and exactly how comptime evaluation unfolds, all without a wall of explanatory prose getting in the way.

The Go by Example lineage is worth noting. Mark McGranaghan's site became a go-to reference precisely because working programmers learn faster from concrete code than from abstract description. Zig by Example makes the same bet.

Where It Fits in the Ecosystem

The repo's Further Reading section points to the official Zig documentation, the standard library source, Zig Learn, Zig News, and Ziglings (an exercises-based learning tool). Zig by Example occupies a different niche than Ziglings — rather than guided fill-in-the-blank exercises, it's a reference you skim when you hit an unfamiliar construct in real code.

For developers already writing C for embedded systems, OS tooling, or performance-critical libraries, the C Interop example alone is worth bookmarking. Zig's ability to incrementally replace C files in an existing build is one of its most pragmatic selling points, and seeing a concrete annotated example of how that boundary works lowers the activation energy considerably.

The project is open to contributions — see CONTRIBUTING.md in the repo — so the community can fill gaps as the language evolves past 0.14.
