Zig Language
Core language features, data types, and idioms for writing Zig code.
Anti-fabrication
This skill follows core:anti-fabrication. Verified against zig 0.16.0 (locally
installed, claude-skills-204) by compiling the documented snippets:
references/language.md's defer example opened a file with std.fs.cwd(), which does
not exist at 0.16.0 — rewritten against std.Io.Dir.cwd().openFile(io, ...) /
file.close(io), with the pre-0.16 form kept as a note for readers on older
toolchains. Re-verify against a locally installed zig version before asserting a
std API this skill doesn't cover — Zig is pre-1.0 and std breaks across minor
releases.
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
