App
---

[](#app)

Check out the [**App Skeleton**](https://github.com/tobento-ch/app-skeleton) if you are using the skeleton.

You may also check out the [**App**](https://github.com/tobento-ch/app) to learn more about the app in general.

Language Boot
-------------

[](#language-boot)

The language boot does the following:

- installs and loads language config file
- language interfaces implementation based on config
- determines current language
- sets current language on the [date formatter](https://github.com/tobento-ch/app#dater-boot)

```
use Tobento\App\AppFactory;

// Create the app
$app = new AppFactory()->createApp();

// Add directories:
$app->dirs()
    ->dir(realpath(__DIR__.'/../'), 'root')
    ->dir(realpath(__DIR__.'/../app/'), 'app')
    ->dir($app->dir('app').'config', 'config', group: 'config')
    ->dir($app->dir('root').'public', 'public')
    ->dir($app->dir('root').'vendor', 'vendor');

// Adding boots:
$app->boot(\Tobento\App\Language\Boot\Language::class);

// Run the app:
$app->run();
```

### Language Config

[](#language-config)

The configuration for the language is located in the `app/config/language.php` file at the default App Skeleton config location.

### App Languages

[](#app-languages)

```
use Tobento\App\AppFactory;
use Tobento\Service\Language\LanguagesInterface;

$app = new AppFactory()->createApp();

// Add directories:
$app->dirs()
    ->dir(realpath(__DIR__.'/../'), 'root')
    ->dir(realpath(__DIR__.'/../app/'), 'app')
    ->dir($app->dir('app').'config', 'config', group: 'config')
    ->dir($app->dir('root').'public', 'public')
    ->dir($app->dir('root').'vendor', 'vendor');

// Adding boots:
$app->boot(\Tobento\App\Language\Boot\Language::class);
$app->booting();

// Gets the app languages:
$languages = $app->get(LanguagesInterface::class);

// Run the app:
$app->run();
```

You may check out the [**Language Service**](https://github.com/tobento-ch/service-language) to learn more about it.

### Current And Default App Language

[](#current-and-default-app-language)

```
use Tobento\App\AppFactory;
use Tobento\Service\Language\LanguagesInterface;
use Tobento\Service\Language\LanguageInterface;

$app = new AppFactory()->createApp();

// Add directories:
$app->dirs()
    ->dir(realpath(__DIR__.'/../'), 'root')
    ->dir(realpath(__DIR__.'/../app/'), 'app')
    ->dir($app->dir('app').'config', 'config', group: 'config')
    ->dir($app->dir('root').'public', 'public')
    ->dir($app->dir('root').'vendor', 'vendor');

// Adding boots:
$app->boot(\Tobento\App\Language\Boot\Language::class);
$app->booting();

// Gets the app languages:
$languages = $app->get(LanguagesInterface::class);

// Current language:
$currentLanguage = $languages->current();
// var_dump($currentLanguage instanceof LanguageInterface);
// bool(true)

// Default language:
$defaultLanguage = $languages->default();
// var_dump($defaultLanguage instanceof LanguageInterface);
// bool(true)

// Run the app:
$app->run();
```

You may check out the [**Language Service**](https://github.com/tobento-ch/service-language) to learn more about it.

### Resolving Current Language

[](#resolving-current-language)

By default, the current language is resolved by the `Tobento\App\Language\CurrentLanguageRouterResolver::class`. You may change the implementation in the language config.

### Localizing Routes

[](#localizing-routes)

You may localize your routes by the following way:

```
use Tobento\App\AppFactory;
use Tobento\App\Language\RouteLocalizerInterface;
use Tobento\Service\Language\LanguagesInterface;

$app = new AppFactory()->createApp();

// Add directories:
$app->dirs()
    ->dir(realpath(__DIR__.'/../'), 'root')
    ->dir(realpath(__DIR__.'/../app/'), 'app')
    ->dir($app->dir('app').'config', 'config', group: 'config')
    ->dir($app->dir('root').'public', 'public')
    ->dir($app->dir('root').'vendor', 'vendor');

// Adding boots:
$app->boot(\Tobento\App\Language\Boot\Language::class);
$app->booting();

// Localize Routes:
$routeLocalizer = $app->get(RouteLocalizerInterface::class);

$route = $app->route('GET', '{?locale}/team', function(LanguagesInterface $languages): array {
    return ['page' => 'team', 'locale' => $languages->current()->locale()];
})->name('team');

$routeLocalizer->localizeRoute($route);

/*
print_r($app->routeUrl('team')->translated());
Array
(
    [de] => https://example.com/de/team
    [en] => https://example.com/team
)
*/

// Run the app:
$app->run();
```

**Translation Routing**

Simply, install the [App Translation](https://github.com/tobento-ch/app-translation) bundle and boot the `\Tobento\App\Translation\Boot\Translation::class`:

```
composer require tobento/app-translation

```

```
use Tobento\App\AppFactory;
use Tobento\App\Language\RouteLocalizerInterface;
use Tobento\Service\Language\LanguagesInterface;
use Tobento\Service\Translation\TranslatorInterface;
use Tobento\Service\Translation\Resource;

$app = new AppFactory()->createApp();

// Add directories:
$app->dirs()
    ->dir(realpath(__DIR__.'/../'), 'root')
    ->dir(realpath(__DIR__.'/../app/'), 'app')
    ->dir($app->dir('app').'config', 'config', group: 'config')
    ->dir($app->dir('root').'public', 'public')
    ->dir($app->dir('root').'vendor', 'vendor');

// Adding boots:
$app->boot(\Tobento\App\Language\Boot\Language::class);
$app->boot(\Tobento\App\Translation\Boot\Translation::class);
$app->booting();

// Add routes translations:
$app->on(TranslatorInterface::class, function(TranslatorInterface $translator) {
    $translator->resources()->add(new Resource(
        name: 'routes',
        locale: 'en',
        translations: [
            'checkout' => 'checkout', 'payment' => 'payment',
            'products' => 'products', 'edit' => 'edit'
        ],
    ));
    $translator->resources()->add(new Resource(
        name: 'routes',
        locale: 'de',
        translations: [
            'checkout' => 'kasse', 'payment' => 'zahlung',
            'products' => 'produkte', 'edit' => 'bearbeiten',
        ],
    ));
});

// Localize Routes:
$routeLocalizer = $app->get(RouteLocalizerInterface::class);

$route = $app->route('GET', '{?locale}/{checkout}/{payment}', function(LanguagesInterface $languages) {
    return ['page' => 'checkout', 'locale' => $languages->current()->locale()];
})->name('checkout.payment');

// checkout and payment will be translated
// by the TranslatorInterface::class if implemented, otherwise
// checkout and payment is used:
$routeLocalizer->localizeRoute($route, 'checkout', 'payment');

/*
print_r($app->routeUrl('checkout.payment')->translated());
Array
(
    [de] => https://example.com/de/kasse/zahlung
    [en] => https://example.com/checkout/payment
)
*/

// Resource example:
$routeResource = $app->routeResource('{?locale}/{products}', ResourceController::class)->name('products');

$routeLocalizer->localizeRoute($routeResource, 'products', 'edit.edit');
// define resource verbs with a dot if you want to translate them too!
// e.g. 'create.create' or 'edit.edit'

/*
print_r($app->routeUrl('products.edit', ['id' => 5])->translated());
Array
(
    [de] => https://example.com/de/produkte/5/bearbeiten
    [en] => https://example.com/products/5/edit
)
*/

// Run the app:
$app->run();
```

By default, translations are loaded from the `routes` [named resources](https://github.com/tobento-ch/service-translation#translate-message).

You may change the localization strategy by changing the `RouteLocalizerInterface::class` implemenation in the language config file.

### Localizing Routes With Domains

[](#localizing-routes-with-domains)

You will need to specify the languages with its domain in the `app/config/language.php` file:

```
// ...
$storage = new InMemoryStorage([
    'languages' => [
        1 => [
            'id' => 1,
            'locale' => 'de-DE',

            // The key is used for translations and storing resources!
            'key' => 'de',

            'domain' => 'example.de',
            'default' => true,
        ],
        2 => [
            'id' => 2,
            'locale' => 'de-CH',

            // The key is used for translations and storing resources!
            'key' => 'de',
            // or if specific translations and storing resources!
            //'key' => 'de-CH',

            'slug' => 'de',
            'domain' => 'example.ch',
            'fallback' => 'de-DE',
            'default' => true,
        ],
        3 => [
            'id' => 3,
            'locale' => 'fr-CH',
            'slug' => 'fr',
            'domain' => 'example.ch',
            'fallback' => 'de-DE',
        ],
    ],
]);
// ...
```

**App Example**

```
use Tobento\App\AppFactory;
use Tobento\App\Language\RouteLocalizerInterface;
use Tobento\Service\Translation\TranslatorInterface;

$app = new AppFactory()->createApp();

// Add directories:
$app->dirs()
    ->dir(realpath(__DIR__.'/../'), 'root')
    ->dir(realpath(__DIR__.'/../app/'), 'app')
    ->dir($app->dir('app').'config', 'config', group: 'config')
    ->dir($app->dir('root').'public', 'public')
    ->dir($app->dir('root').'vendor', 'vendor');

// Adding boots:
$app->boot(\Tobento\App\Language\Boot\Language::class);
$app->booting();

// Localize Routes:
$routeLocalizer = $app->get(RouteLocalizerInterface::class);

$route = $app->route('GET', '{?locale}/team', function(null|string $locale): array {
    return ['page' => 'team', 'locale' => $locale];
})->name('team');

$routeLocalizer->localizeRoute($route);

/*
print_r($app->routeUrl('team')->domained());
Array
(
    [example.ch] => http://example.ch/team
    [example.de] => http://example.de/team
)

print_r($app->routeUrl('team')->domain('example.ch')->translated());
Array
(
    [de] => http://example.ch/team
    [fr] => http://example.ch/fr/team
)

print_r($app->routeUrl('team')->domain('example.de')->translated());
Array
(
    [de-de] => http://example.de/team
)
*/

// Run the app:
$app->run();
```

### Area Languages

[](#area-languages)

```
use Tobento\App\AppFactory;
use Tobento\Service\Language\AreaLanguagesInterface;
use Tobento\Service\Language\LanguagesInterface;

$app = new AppFactory()->createApp();

// Add directories:
$app->dirs()
    ->dir(realpath(__DIR__.'/../'), 'root')
    ->dir(realpath(__DIR__.'/../app/'), 'app')
    ->dir($app->dir('app').'config', 'config', group: 'config')
    ->dir($app->dir('root').'public', 'public')
    ->dir($app->dir('root').'vendor', 'vendor');

// Adding boots:
$app->boot(\Tobento\App\Language\Boot\Language::class);
$app->booting();

// Gets the area languages:
$areaLanguages = $app->get(AreaLanguagesInterface::class);

// Run the app:
$app->run();
```
