Extending
Translator Structure
The final major extension is a translator, which usually uses a third party translation service. It extends the \Twigger\Translate\Translate\Translator class, and defines methods to translate a line to another language.
You may also override the translateMany method, to optimise translating multiple strings at a time. This is optional though.
To access any configuration, such as keys or endpoints, you can use the getConfig function.
class GoogleTranslator extends \Twigger\Translate\Translate\Translator
{
protected $google;
public function __construct(array $config = [], \App\Services\GoogleTranslate $google) {
parent::__construct($config);
$this->google = $google;
}
public function translate(string $line, string $to, string $from): ?string
{
$password = $this->getConfig('password', 'default-password');
return $this->google->translate($line, $to, $from, $password);
}
public function translateMany(array $lines, string $to, string $from): array
{
return $this->google->translateMany($lines, $to, $from);
}
}
Register a Translator
Having created a translator, you need to register it as a driver. This way, it can be used in configurations. You’ll also need to write a callback that will return an instance of the translator, with dependencies passed in.
\Twigger\Translate\Translate::pushDriver('google', function ($app, $config) {
return new GoogleTranslator($config, $app->make(\App\Services\GoogleTranslate::class));
});
