Zig Language

Core language features, data types, and idioms for writing Zig code.

When to Use This Skill

Activate when:

• Writing Zig code with structs, enums, unions, optionals
• Using comptime for compile-time execution and generics
• Handling errors with error unions, try, catch, errdefer
• Working with slices, arrays, pointers, and strings
• Using defer/errdefer for resource cleanup

Key Topics

For detailed syntax, patterns, and examples, see references/language.md.

Topics covered:

• Comptime: compile-time execution, generics via comptime parameters, key builtins
• Error handling: error sets, error unions, try/catch, errdefer, merging error sets
• Data types: structs, packed structs, enums, tagged unions, optionals
• Slices, arrays, pointers, and sentinel-terminated types
• Strings as []const u8 byte slices
• Resource cleanup with defer/errdefer (LIFO execution order)
• Naming conventions and formatting style
