EventGenerateCommand.php

TLDR

This file contains the EventGenerateCommand class that generates missing events and listeners based on registration.

Methods

handle

This method executes the console command. It retrieves the providers that implement the EventServiceProvider class and generates the events and listeners based on their registrations.

makeEventAndListeners

This method creates the event and listeners for a given event. It checks if the event name contains a backslash and if it does, it calls the make:event and makeListeners methods.

makeListeners

This method creates the listeners for a given event. It iterates over the listeners array, removes any method suffix, and calls the make:listener command with the appropriate arguments.
