Zig Tutorial

Zig is a blazing fast, statically typed, compiled systems programming language with a modern C-like syntax, offering low-level control, built-in memory safety, and powerful meta-programming capabilities. It prioritizes developer happiness with clear error messages, a friendly compiler, and an active community.

Scope: Study the topics in order, compile each example with the Zig toolchain, and use the official manual for authoritative depth.

#	ZIG	Topic	Description
PHASE 1: FOUNDATIONS
	01	Why Zig & Thinking in Zig	Origins, purpose, paradigms: no hidden control flow or allocation, no macros.
	02	Toolchain & Environment	Install Zig, run your first program, and understand the four build modes.
	03	Statements & Expressions	Punctuation, operators, identifiers, comments, and compiler builtins.
PHASE 2: TYPES & CONTROL
	04	Data Types & Literals	Explicit-width integers, floats, bools, arrays, and compile-time literals.
	05	Control Flow	if, switch, while, and for — every construct is an expression.
	06	Functions & Cleanup	Parameters, return values, defer, errdefer, and inline functions.
PHASE 3: THE CORE OF ZIG
	07	Compile-Time Metaprogramming	comptime parameters and variables: generics and reflection in the language itself.
	08	Pointers & Slices	Single-item pointers, many-item pointers, slices, alignment, and casting.
	09	Optionals & Null Safety	Nullable values are explicit in the type: ?T, null, orelse, and unwrapping.
	10	Errors & Error Unions	Error sets, error unions, try, catch, and errdefer — errors are values.
PHASE 4: MEMORY & DATA
	11	Allocators & Memory	Explicit allocators, arena cleanup, and leak detection — no hidden allocation.
	12	Strings, Formatting & Files	Strings are byte slices, formatting is explicit, and file I/O needs an allocator.
	13	Structs, Enums & Unions	Data modeling with struct, enum, tagged union, and exhaustive switch.
PHASE 5: TOOLING & INTEROP
	14	Build System	build.zig, build steps, and the zig build / run / test workflow.
	15	C Interop	Import C headers with @cImport, link C libraries, and share types.
	16	Testing & Debugging	zig test, test blocks, safety checks, leak detection, and formatter.
PHASE 6: PRACTICE & DEMO
	17	Lab Examples	Run and modify single-file practice demos for every lesson.
	18	Study Projects	Small composed projects that combine everything: algorithms and CLI tools.
PHASE 7: REFERENCE
	19	References & Compilers	Browser playgrounds, official docs, courses, and sample repositories.
