Marble Translate

Machine translation for Marble CMS item field values using DeepL or Google Translate.

Installation

composer require marblecms/marble-translate
php artisan marble:translate:install

Publish config:

php artisan vendor:publish --tag=translate-config

Configuration (config/translate.php)

Key	Default	Description
provider	deepl	Default provider: deepl or google
api_key	''	API key for the chosen provider
deepl_pro	false	Use DeepL Pro endpoint (api.deepl.com vs api-free.deepl.com)

.env variables:

TRANSLATE_PROVIDER=deepl
TRANSLATE_API_KEY=your-key-here
TRANSLATE_DEEPL_PRO=false

How it works

1. Admin visits Structure → Translate to see all published items with translatable fields
2. Items show a per-language coverage indicator (tick = translated, "Missing" = not yet)
3. Click the arrow button to open the translation workspace for an item
4. Select source language, target language, and provider; click Translate
5. The plugin calls the API and creates a pending TranslationJob with the results
6. Review the source vs. translated values in the diff table
7. Click Apply All to write the translations back to item_values, or Reject to discard

Applying a job fires the ItemTranslated event.

Providers

DeepL

Uses the DeepL API v2. Free tier uses api-free.deepl.com; Pro tier uses api.deepl.com (set TRANSLATE_DEEPL_PRO=true).

Google Cloud Translation

Uses the Cloud Translation Basic (v2) API. Requires a Cloud Translation API key.

Extending with a custom provider

Implement a provider class with this interface:

public function translate(array $texts, string $sourceLang, string $targetLang): array;

Then extend TranslationService::resolveProvider() or bind your provider in a service provider.
