Magento 2 - Twig Template Engine

Module implementing Twig as Magento 2 template engine. It works with default .phtml templates as fallback.

Installation

1. Install module via composer composer require clawrock/magento2-twig-engine
2. Register module php bin/magento setup:upgrade

Compatibility

• Magento 2.2 - 2.3
• PHP 7.0 - 7.2

Configuration

There is no system.xml file, because Twig configuration should be only edited by developers.

Auto resolve option

This module can automatically look for twig files. For example if you want to use twig template in Magento\Theme\Block\Html\Title block just add file in app/design/frontend/Vendor/theme/Magento_Theme/templates/html/title.html.twig. If you disable auto resolve you will have to update each block template manually:

<referenceBlock name="page.main.title" template="Magento_Theme::html/title.html.twig"/>

Auto resolve option works the same as Magento 2 template resolver. For example if your theme is Luma and template is Magento_Theme::html/title.phtml it will check possible paths in following order until first existing file:

vendor/magento/theme-frontend-luma/Magento_Theme/templates/html/title.html.twig
vendor/magento/theme-frontend-luma/Magento_Theme/templates/html/title.twig
vendor/magento/theme-frontend-luma/Magento_Theme/templates/html/title.phtml

vendor/magento/theme-frontend-blank/Magento_Theme/templates/html/title.html.twig
vendor/magento/theme-frontend-blank/Magento_Theme/templates/html/title.twig
vendor/magento/theme-frontend-blank/Magento_Theme/templates/html/title.phtml

vendor/magento/module-theme/view/frontend/templates/html/title.html.twig
vendor/magento/module-theme/view/frontend/templates/html/title.twig
