// Test 168: Import Registers Taps Automatically
//
// Tests that importing a module automatically registers any taps defined in it.
// This is the mechanism that makes `~[profile]import "std/profiler"` work -
// the import adds the module's universal taps to the tap registry, enabling
// full-program instrumentation with a single line.
//
// Structure:
//   test_lib/
//     logger.kz  → Defines a universal tap ~tap(* -> *) that logs all events
//
// Expected: The logger's tap fires for ALL events, even though we didn't
//          explicitly write the tap pattern in this file.
//
// This demonstrates "ambient" behavior - importing makes taps active.

const std = @import("std");

// Import the logger module (which defines universal taps)
~import app/test_lib/logger

// Define some events to test with
~tor compute { x: i32 } -> i32

~tor format { value: i32 } -> string

~tor display { text: string }

~proc compute|zig {
    std.debug.print("compute({d})\n", .{x});
    return x * 2;
}

~proc format|zig {
    std.debug.print("format({d})\n", .{value});
    // Allocate temporary string for testing
    const text = "formatted";
    return text;
}

~proc display|zig {
    std.debug.print("Final: {s}\n", .{text});
}

// Call events - the logger's universal tap should intercept them!
~compute(x: 42): r |> format(value: r): f |> display(text: f)
