Generating Code with comptime

Emit repetitive logic automatically.

Let the Compiler Write Repetition

Instead of copying near-identical code, you describe the pattern once and let comptime emit each variation for you. ⚙️

An inline for over a comptime list expands into separate statements, one per item, all baked into the final program.

inline for (.{ 1, 2, 3 }) |n| {
    std.debug.print("{}\n", .{n});
}
