Zig's comptime turns generics, lookup tables, and compile-time validation into ordinary Zig code. A worked fixed-capacity stack example, plus the real trade-offs: compile times, error messages, and version churn.
Zig's comptime replaces macros and templates with ordinary code evaluated by the compiler. Here's how it powers zero-cost generics, with a ring buffer example and the trade-offs.
MissingMethodException after adding @CompileStatic? Static compilation bypasses Groovy's dynamic dispatch. Diagnose methodMissing, propertyMissing, and GDK call failures and fix them selectively.
Zig's comptime replaces macros, templates, and code generators with one mechanism: ordinary Zig functions executed at compile time. A look at generics, a worked JSON serializer, and the real costs.
Functions can't delay evaluation of their arguments — macros can. A practical look at Racket's define-syntax-rule, hygiene, and the macro stepper, with worked examples and honest trade-offs.
A decision guide for Zig's comptime versus runtime error unions: when each applies, their costs, and a working example you can compile and verify.
Zig's comptime runs ordinary Zig code during compilation to produce constants and per-type specializations, replacing separate macro systems. Here is a worked table example, its limits, and how to verify it on your toolchain.
Zig's comptime feature runs functions at compile time, letting you embed pre‑computed tables directly in the binary.
Learn how Nim's compile-time macros eliminate boilerplate and runtime reflection by manipulating the AST, allowing for high-performance code generation without runtime overhead.
