Laratext for Laravel

Introduction

Laratext is a Laravel package designed to manage and auto-translate your application's text strings. In laravel, when using the __ gettext helper method you specify the translation or the key. Both options have issues. If you specify the key, the file becomes difficult to read, as you don't know what's there. If you specify the text, your translations will break if you change a single character. With Laratex you specify both the key and the text, makint it useful and readable.

It also allows you to seamlessly integrate translation services (like OpenAI or Google Translate) into your Laravel application to automatically translate missing translation keys across multiple languages.

It includes these features:

• Simplifies working with language files in Laravel.
• Auto-translate missing translation keys to multiple languages.
• Supports multiple translation services (e.g., OpenAI, Google Translate).
• Easy-to-use Blade directive (@text) and helper functions (text()).
• Commands to scan and update translation files.

Installation

Execute the following command in your Laravel root project directory:

composer require edulazaro/laratext

To publish the configuration run:

php artisan vendor:publish" --tag="texts"

Or if for some reason it does not work:

php artisan vendor:publish --provider="EduLazaro\Laratext\LaratextServiceProvider" --tag="texts"

This will generate the texts.php configuration file in the config folder.

Configuration

The texts.php configuration file contains all the settings for the package, including API keys for translation services, supported languages, and more.

Example of the configuration (config/texts.php):

return [
    // Default Translator
    'default_translator' => EduLazaro\Laratext\Translators\OpenAITranslator::class,

    // Translator Services
    'translators' => [
        'openai' => EduLazaro\Laratext\Translators\OpenAITranslator::class,
        'google' => EduLazaro\Laratext\Translators\GoogleTranslator::class,
    ],

    // OpenAI Configuration
    'openai' => [
        'api_key' => env('OPENAI_API_KEY'),
        'model' => env('OPENAI_MODEL', 'gpt-3.5-turbo'),
        'timeout' => 10,
        'retries' => 3,
    ],

    // Google Translator Configuration
    'google' => [
        'api_key' => env('GOOGLE_TRANSLATOR_API_KEY'),
        'timeout' => 10,
        'retries' => 3,
    ],

    // List the supported languages for translations.
    'languages' => [
        'en' => 'English',
        'es' => 'Spanish',
        'fr' => 'French',
    ],
];

This configuration allows you to define your translation services, API keys, and the supported languages in your Laravel application.

This is an example of the .env:

OPENAI_API_KEY=your_openai_api_key
GOOGLE_TRANSLATOR_API_KEY=your_google_api_key

Usage

Here is how you can use the blade directive and the text function:

Use the text() helper function to fetch translations within your PHP code.

text('key_name', 'default_value');

Use the @text Blade directive to fetch translations within your views.

@text('key_name', 'default_value')

Scanning Translations

You can use the laratext:scan command to scan your project files for missing translation keys and optionally translate them into multiple languages.

php artisan laratext:scan --write --lang=es --translator=google

These are the command Options:

• --write: Write the missing keys to the language files.
• --lang: Target a specific language for translation (e.g., es for Spanish).
• --dry Perform a dry run (do not write).
• --diff: Show the diff of the changes made.
• --translator: Specify the translator service to use (e.g., openai or google).

Creating translators

To create a custom translator, you need to implement the TranslatorInterface. This will define the structure and method that will handle the translation.

To facilitate the creation of custom translators, you can create a make:translator command that will generate the required files for a new translator class.

To create a translator run:

php artisan make:translator BeautifulTranslator

This will create the BeautifulTranslator.php file in the app/Translators directory:

namespace App\Translators;

use EduLazaro\Laratext\Contracts\TranslatorInterface;

class BeautifulTranslator implements TranslatorInterface
{
    public function translate(string $text, string $from, array $to): array
    {
        // TODO: Implement your translation logic here.

        $results = [];

        foreach ($to as $language) {
            $results[$language] = $text; // Dummy return same text
        }

        return $results;
    }
}
