MonkeysLegion Core v2

High-performance framework kernel with typed config, service providers, pipeline, and PHP 8.4 primitives for the MonkeysLegion framework.

Features

Feature	Status
PHP 8.4 Native	Property hooks, backed enums, readonly classes, new in initializers
3 Attributes	#[Provider], #[BootAfter], #[Config]
Application Kernel	Provider registration, topological boot ordering, lifecycle hooks
Generic Pipeline	Immutable, zero-reflection, multi-pipe-type support
Exception Handler	Environment-aware: full debug local, sanitized in production
Error Rendering	Error Renderer contract + implementation for CLI/debug output
Typed Config	Dot-notation, O(1) cached lookups, type-safe getters
Arr Utilities	dot/undot, flatten, pluck, groupBy, sortBy, first/last
Str Utilities	camel/snake/kebab/studly, slug, UUID/ULID, mask, random (CSPRNG)
Benchmark	hrtime precision, memory measurement, comparison
Once (Memoization)	Rust-inspired call-once with keyed caching
PSR-20 Clock	Testable system clock
20+ Helper Functions	env, paths, retry, rescue, tap, value, blank/filled

Quick Start

Kernel Boot

use MonkeysLegion\Core\Kernel\Kernel;
use MonkeysLegion\Core\Environment\Environment;

$kernel = new Kernel(
    container: $container,
    environment: Environment::Production,
);

$kernel->register(new DatabaseProvider());
$kernel->register(new AuthProvider());
$kernel->boot();

// ... handle request ...

$kernel->terminate();

Service Providers

use MonkeysLegion\Core\Attribute\Provider;
use MonkeysLegion\Core\Attribute\BootAfter;
use MonkeysLegion\Core\Contract\Bootable;
use MonkeysLegion\Core\Provider\AbstractProvider;

#[Provider(priority: 10)]
#[BootAfter(DatabaseProvider::class)]
final class AuthProvider extends AbstractProvider implements Bootable
{
    public function register(): void
    {
        // Register bindings
    }

    public function boot(): void
    {
        // Boot after DatabaseProvider
    }
}

Pipeline

use MonkeysLegion\Core\Pipeline\Pipeline;

$result = (new Pipeline())
    ->send($request)
    ->through([
        TrimStrings::class,
        ValidateInput::class,
        AuthenticateUser::class,
    ])
    ->then(fn($req) => $handler->handle($req));

Config

use MonkeysLegion\Core\Config\ConfigRepository;

$config = new ConfigRepository([
    'database' => [
        'host' => 'localhost',
        'port' => 5432,
    ],
]);

$host = $config->string('database.host');       // 'localhost'
$port = $config->int('database.port');           // 5432
$ssl  = $config->bool('database.ssl', false);    // false

Exception Handling

use MonkeysLegion\Core\Exception\Handler;
use MonkeysLegion\Core\Exception\HttpException;

// In production: generic messages, no stack traces
$handler = new Handler(Environment::Production, $logger);

try {
    throw HttpException::notFound('User not found');
} catch (\Throwable $e) {
    $handler->report($e);
    $response = $handler->render($e);
    // { error: true, status: 404, message: "User not found" }
}

Utilities

use MonkeysLegion\Core\Support\{Arr, Str, Benchmark, Once};

// Arrays
Arr::get($data, 'user.address.city', 'Unknown');
Arr::dot(['a' => ['b' => 1]]);  // ['a.b' => 1]

// Strings
Str::uuid();                    // 'f47ac10b-58cc-...'
Str::slug('Hello World!');      // 'hello-world'
Str::mask('secret123', '*', 3); // 'sec******'
Str::random(32);                // CSPRNG-backed

// Benchmark
$ms = Benchmark::measure(fn() => expensiveQuery(), iterations: 100);

// Memoization
$value = Once::callKeyed('config', fn() => loadConfig());

Performance & Security

Performance

• ConfigRepository: O(1) cached dot-notation lookups after first access
• Pipeline: Zero reflection, no container resolution overhead
• Kernel: Topological sort (Kahn's algorithm) runs once during boot
• Benchmark: hrtime() for nanosecond precision
• Arr/Str: Static methods with zero state, minimal allocations

Security

• Exception Handler: Never exposes stack traces, file paths, or internal details in production
• Str::random(): CSPRNG-backed via random_int()
• Str::uuid()/ulid(): CSPRNG-backed via random_bytes()
• env(): Only reads from server environment, never from user input
• HttpException: Client-safe messages; internal details via $previous
• Kernel::terminate(): Catches all exceptions to prevent information leaks
• Str::mask(): Safely hides sensitive data (tokens, API keys)
