README

A TYPO3 backend module for editing translation labels (locallang files) without modifying the original extension files. This extension's intended goal is to allow editors to independently translate frontend labels without requiring developer involvement.

Features

• 📝 Edit labels - Customize any label from any extension
• 🌍 Multi-language support - Edit multiple languages simultaneously
• ➕ Add custom labels - Create new labels that don't exist in the original files
• 🔍 Search & filter - Quickly find labels
• 🎯 Non-destructive - Original extension files remain untouched

Works with locallang_formats if you want to use YAML, JSON, or PHP array files instead of XLF.

📋 Requirements

• TYPO3 13.4
• PHP 8.2

📦 Installation

composer require amdeu/typo3-label-editor

🛠️ Usage

Access the Module

Navigate to Site Management → Label Editor in the TYPO3 backend.

Add an Extension

1. Find the extension you want to edit in the "Add Extension" section
2. Click the "+" button to add it to management
3. The extension's locallang files are now available for editing

Edit Labels

1. Select an extension from the "Managed Extensions" list
2. Choose the label file from the dropdown
3. Select one or more languages using the checkboxes
4. Edit labels in the table:
   • Single language view: Shows original and custom override
   • Multi-language view: Shows override for each selected language
5. Click "Save" in the document header

Add Custom Labels

1. Enter a label key (e.g., my.custom.label) in the input field
2. Click "+"
3. The label is created across all language files
4. Fill in the values and save

Search Labels

Use the search box above the table to filter labels by key or value in real-time.

Remove an Extension

1. Click the trash icon next to a managed extension
2. Confirm the warning dialog
3. All custom label overrides for that extension will be deleted

Configuration

Extension Configuration in Backend:

System > Settings > Extension Configuration > label_editor

• allowedExtensions: Restrict which extensions can be edited. Comma-separated list of extension keys. If empty, all extensions are allowed.

💡 How It Works

The extension uses TYPO3's locallangXMLOverride/resourceOverrides feature:

1. When you add an extension, a registry is created at var/label_editor/registry.json
2. Custom labels are stored in var/label_editor/overrides/{extension}/{file}.xlf
3. TYPO3 merges these override files with the original locallang files
4. Original extension files remain unchanged
