Laravel-Translator for PHP and Vue

This is a forked version of Laravel-Translator (https://github.com/thiagocordeiro/laravel-translator) which adds the ability to separate generation of Vue translation files and PHP translation files. It's slightly refactored to play nicely with translated strings rather than named keys.

Follow these simple rules when adding translations

• Always use __() instead of lang(), trans() etc
• Any strings that contain a " must use " instead
• Always use "" instead of '' on the string, i.e. {{ __("String that can be translated") }}
• Always use '' instead of "" on any embedded HTML, i.e. <a href=''></a>
• Always use {!! !!} instead of {{ }} when embedding HTML
• Never break translations onto a new line, it will create additional spaces / tabs
• For pluralisation, casing etc refer to: https://laravel.com/docs/5.6/localization

Translations in Laravel Blades

For simple strings:

{{ __("String that can be translated") }}

For strings with variables

{{ __("Hi :name, welcome to :app", ['name' => 'Scott', 'app' => 'Widgets 3000']) }}

Translations in Javascript/Vue

Translations not updating? Clear the cache! $ php artisan cache:clear

Strings used in Vue templates and Javascript code are stored in /resources/lang/_javascript/ and are handled separately from general PHP/system translations. This is to ensure the visitor only downloads translations that are used in JS, keeping file sizes small for faster downloads.

We load <script src="/js/lang-{lang}.js"></script> on every page of the system. The URL is actually a Laravel route which loads the corresponding language file (e.g. /resources/lang/_javascript/{lang}.json) and returns a json encoded string of the translations. This string is stored in the variable: window.i18n, which can then be referenced by Javascript.

During the generation of this string will tell Laravel to cache this response forever. Therefore if you ever update the translation file you need to clear the cache via php artisan cache:clear.

To keep the logic of translations consistent, we have a Vue prototype variable of __ which handles the conversion of the translations (in /resources/assets/js/app.js):

For simple strings:

{{ __("String that can be translated") }}

For strings with variables:

{{ __("Hi :name, welcome to :app", {'name': 'Scott', 'app', 'Widgets 3000'}) }}

Laravel-translator scans your project resources/view/ resources/js/ and app/ folder to find lang(...) and __(...) functions, then it create keys based on first parameter value and insert into json translation files.

Installation

You just have to require the package

This package register the provider automatically, See laravel package discover.

After composer finish it's installation, you'll be able to update your project translation keys running the following command:

if for any reason artisan can't find translator:update command, you can register the provider manually on your config/app.php file:

Usage

First you have to create your json translation files:

Keep working as you are used to, when laravel built-in translation funcion can't find given key, it'll return itself, so if you create english keys, you don't need to create an english translation

also you can use params on translation keys

Output

translator:update command will scan your code to identify new translation keys, then it'll update all json files on app/resources/lang/ folder appending this keys.
