Yireo AdditionalLanguageFile

Magento version PHP version License Latest Version

This Magento 2 module adds the ability to add an extra language file to your theme.

Overview

Every theme has the ability to override language strings in a file like i18n/en_US.csv. This module allows you to add a second file i18n/en_US_additional.csv which is loaded on top of the original file. The benefit of this is that you can have a parent theme that fills up the en_US.csv which is then inherited in the child theme. Yet using this module, you can make specific overrides in the additional language file.

Installation

Install this module within Magento 2 using composer:

composer require yireo/magento2-additional-language-file

And of course afterwards use the regular commands to enable the module.

Technical architecture

This module remaps the preference for the original Magento\Framework\Translate file to a new class.
