README

Laravel AI Translator is a powerful package designed to automate the translation of your application's language files using Google Gemini AI Studio API. It simplifies your localization workflow, letting you scale your app to multiple languages with ease and precision.

✨ Features

AI-Powered Translations
High-quality, context-aware translations powered by Google Gemini AI.
Dual File Support
Automatically translates both JSON files (resources/lang/en.json) and PHP array files (resources/lang/en/messages.php).
Smart Updates
Detects and translates only missing or identical keys, preserving your custom edits.
Structured Arrays Preserved
Maintains the original structure of nested PHP arrays without any flattening.
Interactive CLI
Artisan commands make setup, translation, and management intuitive and fast.
Dry Run Mode
Preview translations directly in the console before saving them.
Configurable & Extensible
Customize API keys, source/target languages, and AI prompts via config file.
Laravel Ready
Compatible with Laravel 10.x, 11.x and PHP >= 8.1.
Robust Error Handling
Graceful messaging for API errors and misconfigurations.

🚀 Installation

Install the package via Composer:

composer require anuragsingk/laravel-ai-translator

🛠️ Setup

Before you begin, you’ll need a Google Gemini API Key.
👉 Generate your API Key from Google AI Studio

After that, run the setup command to configure the package:

php artisan ai-translate:setup

This command will:

Prompt for your Gemini API key (saved as AI_TRANSLATOR_API_KEY in .env)
Auto-detect source language files (e.g., en.json, en/messages.php)
Attempt to auto-detect the source language (e.g., en) and confirm it

Optional: To manually publish the configuration file:

php artisan vendor:publish --tag=ai-translator-config

📖 Usage

Add a New Language

php artisan ai-translate:add-language es

Translates your source language files into a new target language (e.g., Spanish es) and saves them as:

resources/lang/es.json
resources/lang/es/messages.php

Update Existing Translations

php artisan ai-translate:update

Updates all configured target languages by translating only missing or unchanged keys.

Preview (Dry Run)

php artisan ai-translate:update --dry-run

Previews the translations in your console without writing to any files.

Delete a Language

php artisan ai-translate:delete-language ta

Deletes all language files associated with a specific language code.

List Configured Languages

php artisan ai-translate:list

Displays source and target languages and associated files.

Show Current Configuration

php artisan ai-translate:show-config

Displays the current configuration (API key masked).

📂 File Handling

JSON File Example

{
    "welcome": "Welcome to our application!",
    "greeting": "Hello, {name}!",
    "messages": {
        "success": "Operation completed successfully.",
        "error": "An error occurred."
    }
}

PHP Array File Example

<?php

return [
    'welcome_message' => 'Welcome to our website!',
    'goodbye_message' => 'Goodbye, see you soon!',
    'validation' => [
        'required' => 'The :attribute field is required.',
        'email' => 'The :attribute must be a valid email address.',
    ],
];

The package maintains file structure and nesting in both formats.
