Drago Translator

Lightweight translator for Nette Framework using NEON files, supporting global and module-specific translations.

Requirements

• PHP >= 8.3
• Nette Framework
• Composer

Installation

composer require drago-ex/translator

Extension Registration

Register the DI extension in your NEON configuration.

extensions:
	translator: Drago\Localization\DI\TranslatorExtension(%appDir%, %tempDir%)

Optional configuration

translator:
	autoFinder: false
	translateDirs:
		- %appDir%/First/Translate
		- %appDir%/Second/Translate
	exclude:
		- %appDir%/Temp
		- %appDir%/Legacy

Translator Behavior

• All directories listed in translateDirs are loaded in order.
• Later directories override translations from earlier ones.
• If autoFinder is enabled, the entire application directory is scanned for NEON files.
• Directories listed in exclude are skipped during automatic scanning.

Translation files must be named by language code:

cs.neon
en.neon

Translation File Format

"Hello, world!": "Hello, world!"

Using Translator in Presenters

Add the TranslatorAdapter trait to your presenter:

use Drago\Localization\TranslatorAdapter;

The trait provides:

• persistent language parameter ($lang)
• automatic translator initialization
• template integration

Accessing the Current Language

You can access the currently set language using the following property:

$this->lang;

Getting Translator Instance

To get the initialized translator for the current language:

$this->getTranslator()

Using Translations in Templates

The translator is automatically registered in templates. Example usage in Latte:

{_"Hello, world!"}
{$label|translate}

Using Translator in Forms

To enable translations in forms, set the translator explicitly:

$form->setTranslator($this->getTranslator());

Routing for Language Switching

To support language prefixes, configure your routes accordingly:

$router->addRoute('[<lang=en cs|en>/]<presenter>/<action>', 'Presenter:action');

Switching Languages in Templates

You can switch languages by passing the lang parameter:

<a n:href="this, lang => cs">Czech</a>
<a n:href="this, lang => en">English</a>

Language Switch Widget

The package provides a reusable Latte widget for language switching. When project file copying is handled by drago-ex/project-tools, the widget is copied to:

app/Core/Widget/@lang-switch.latte

Import the widget in your layout:

{import 'path/to/@lang-switch.latte'}

Render language links:

{include lang-switch, lang: 'cs', name: 'Czech'}
<span class="small ps-1 pe-1 text-secondary">|</span>
{include lang-switch, lang: 'en', name: 'English'}

The current language link automatically receives the current class.

Available options:

• lang - target language code.
• name - visible translated label.
• class - optional class added to the link.
• tag - optional wrapper tag: li, div, or span.
• tagClass - optional class added to the wrapper tag.

Use class when the link needs a custom class:

{include lang-switch, lang: 'cs', name: 'Czech', class: 'nav-link'}

Use tag when the link must be wrapped, for example in a dropdown menu:

{include lang-switch, lang: 'cs', name: 'Czech', tag: 'li'}
{include lang-switch, lang: 'en', name: 'English', tag: 'li'}

Use tagClass when the wrapper needs styling:

{include lang-switch, lang: 'cs', name: 'Czech', tag: 'li', tagClass: 'item-wrapper'}

Notes

• Translator loads translations lazily on first use
• Translations are loaded once per request
• Missing keys return the original message
