Laravel Auto Translation

Introduction

Laravel Auto Translation is a robust package designed to simplify and streamline the localization of your Laravel application. By automating the translation of your language files, this package ensures a more efficient workflow. Key features include support for multiple drivers (ChatGPT, Google Translate, and DeepL) and compatibility with both JSON and PHP language files. Two main commands, translate:scan and translate:default, enable seamless scanning and translating of language strings.

Requirements

• PHP >= 8.0
• Laravel 9.x, 10.x, or 11.x

Installation

Install the package using Composer:

composer require vildanbina/laravel-auto-translation

Publish the configuration file:

php artisan vendor:publish --provider="VildanBina\LaravelAutoTranslation\AutoTranslationsServiceProvider"

Configuration

The configuration file is located at config/auto-translations.php. Below is an example of its default settings. Customize these settings to suit your application, such as specifying the default driver or changing the source language.

<?php

return [
    'lang_path' => lang_path(),

    'default_driver' => env('TRANSLATION_DEFAULT_DRIVER', 'chatgpt'),

    'source_language' => env('TRANSLATION_SOURCE_LANGUAGE', 'en'),

    'drivers' => [
        'chatgpt' => [
            'api_key'     => env('CHATGPT_API_KEY'),
            'model'       => env('CHATGPT_MODEL', 'gpt-3.5-turbo'),
            'temperature' => env('CHATGPT_TEMPERATURE', 0.7),
            'max_tokens'  => env('CHATGPT_MAX_TOKENS', 1000),
        ],

        'google' => [
            'api_key' => env('GOOGLE_API_KEY'),
        ],

        'deepl' => [
            'api_key' => env('DEEPL_API_KEY'),
            'api_url' => env('DEEPL_API_URL', 'https://api-free.deepl.com/v2/translate'),
        ],
    ],
];

Setting Up Environment Variables

Add the required API keys to your .env file. Obtain these keys from the respective service providers:

• ChatGPT: Visit OpenAI API documentation to generate an API key.
• Google Translate: Obtain an API key from the Google Cloud Console.
• DeepL: Generate your API key from the DeepL Pro Account.

TRANSLATION_DEFAULT_DRIVER=chatgpt
TRANSLATION_SOURCE_LANGUAGE=en
CHATGPT_API_KEY=your-chatgpt-api-key
GOOGLE_API_KEY=your-google-api-key
DEEPL_API_KEY=your-deepl-api-key

Commands

1. translate:scan

This command scans all PHP files located within the lang/ folder (including nested directories), extracting translatable strings and saving them in a JSON file (lang/texts_to_translate.json). This file serves as the base for subsequent translations.

Signature:

Command	Description
translate:scan	Extracts translatable strings from PHP files in lang/ and saves them in texts_to_translate.json.

Options:

• --lang=: (Optional) Source language code. Defaults to the value in the configuration file.

Usage:

php artisan translate:scan --lang=en

Example Output:

• Extracted strings are stored in lang/texts_to_translate.json.

2. translate:default

This command translates the strings defined in texts_to_translate.json into a specified target language using the chosen translation driver.

Signature:

Command	Description
translate:default	Translates strings from texts_to_translate.json into the specified target language.

Arguments:

• target_lang: Target language code.

Options:

• --source_lang=: (Optional) Source language code. Defaults to the value in the configuration file.
• --driver=: (Optional) Translation driver to use. Defaults to the value in the configuration file.
• --overwrite: (Optional) Overwrite existing translations if they already exist.

Usage:

php artisan translate:default fr --driver=deepl --overwrite

Example Output:

• Translations are stored in respective language files, e.g., lang/fr.json.

Supported Drivers

The package supports:

• ChatGPT: Flexible and context-aware translations.
• Google Translate API: Fast and reliable.
• DeepL API: Known for accurate translations, especially for European languages.

To Do

• Add support for creating custom translation drivers. For example, contributors could implement drivers that use alternative translation APIs, integrate with offline translation tools, or support specific regional dialects.
• Enhance error handling for failed API calls.
• Provide additional options for partial translations in complex projects.
