loop in library tapped from user

✓ Passing This code compiles and runs correctly.

Code

// User code: taps tick from the counter library
// The loop lives in counter.kz - this just observes it

~import std/taps
~import app/counter

const std = @import("std");

~tor log { n: u32 }
~proc log|zig {
    std.debug.print("tick {}\n", .{n});
}

~tap(app/counter:tick -> *)
| next v |> log(n: v)

input.kz

Supporting Files

// JavaScript implementation facet. Events are declared in counter.kz (merged at
// import); this file holds the |js proc bodies.

~proc tick|js {
    if (n < 5) {
        return { tag: "next", next: n + 1 };
    }
    return { tag: "done" };
}

counter.kjs

// Library module: defines tick event and owns the loop

const std = @import("std");

~pub tor tick { n: u32 }
| next u32
| done

~proc tick|zig {
    if (n < 5) {
        return .{ .next = n + 1 };
    }
    return .{ .done = .{} };
}

// The loop lives here - user code taps it
~#loop tick(n: 0)
| next v |> @loop(n: v)
| done |> _
