The article explores advanced usage of Zig's comptime feature to create tagged union subsets, building on Mitchell Hashimoto's work with the Ghostty terminal. It demonstrates how to derive specific union types for different scopes of keyboard actions, improving type safety and compiler checks. The technique helps prevent programming errors by ensuring functions only handle relevant action types through exhaustive switching.
Background
Zig is a systems programming language that emphasizes safety, performance, and explicit behavior. Its comptime feature allows code to be executed at compile-time, enabling powerful metaprogramming capabilities. Tagged unions are a common pattern in systems programming for representing different variants of a type.
