Blade directives are shortcut codes that help to implement basic PHP control structure. For example loop and conditional statements. It helps makes a code snippets clean and easier to understand. @lang directive is one of these. We can use to display messages from specific languages in Laravel Localization.
This is one of the Blade features that makes the html view easier to work with.
The @lang directive helps retrieve translation strings with multi-language support Laravel application.
When using multi language support in a Laravel application to retrieve lines from language files, you may use the __ helper function. This method accepts the file and the key of the translation string as its first argument. For example, to retrieve the welcome translation string from the resources/lang/messages.php language file, you may use the code snippet below.
{{ __('messages.welcome') }}
@lang('messages.welcome')A Blade templating engine, allows you to use the syntax in line 1 to echo the translation string or use the @lang directive.
The @lang directive is compiled in the Illuminate\View\Compilers\BladeCompiler class.
The BladeCompiler is then registered as a singleton in the Illuminate\View\ViewServiceProvider class. You may then add the newly created provider in the providers array inside config/app.php.
You can find the code logic behind the @lang directive, and even create a customizable version of it.
'providers' => [
...
Illuminate\View\ViewServiceProvider::class,
...
],
