It is advised to be used with Laravel IDE Helper, which generates helper files for your IDE, so it'll be able to highlight and understand some Laravel-specific syntax. This package provides an additional IDE helper file for Laravel macros with the syntax you are already used to in Laravel IDE Helper.
Just require it in your Composer file, and you are good to go:
"tutorigo/laravel-ide-macros": "*"
If you are using Laravel 5.4 or lower, you must register the IdeMacrosServiceProvider manually.
Run the following command to publish the configuration file to config/ide-macros.php:
php artisan vendor:publish --provider="Tutorigo\LaravelMacroHelper\IdeMacrosServiceProvider"
Run the following command to generate the macro IDE helpers:
php artisan ide-helper:macros
