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

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

Edit Labels

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

Add Custom Labels

Enter a label key (e.g., my.custom.label) in the input field
Click "+"
The label is created across all language files
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

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

💡 How It Works

The extension uses TYPO3's locallangXMLOverride/resourceOverrides feature:

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