Quickly Search all Magento 2 Controller Files

Here’s a fun pestle command I forgot about.

pestle.phar magento2:search:search_controllers

This command accepts a file path as a single argument, searches through the specified folder for anything that looks like a Magento controller file, and then displays that controller file’s execute method along with its relative file path.

Pipe the resulting output to a file or text editor, and you can quickly search through all Magento’s controller files. For example, today I forgot the syntax for adding a custom handle to a layout update XML file – but with magento2:search:search_controllers the syntax was and a “Ctrl-F handle” away.

$ pestle.phar magento2:search:search_controllers
//...
vendor/magento/module-backend/Controller/Adminhtml/Denied.php
--------------------------------------------------
function execute()
{
    if (!$this->_auth->isLoggedIn()) {
        /** @var MagentoBackendModelViewResultRedirect $resultRedirect */
        $resultRedirect = $this->resultRedirectFactory->create();
        $resultRedirect->setStatusHeader(403, '1.1', 'Forbidden');
        return $resultRedirect->setPath('*/auth/login');
    }
    /** @var MagentoBackendModelViewResultPage $resultPage */
    $resultPage = $this->resultPageFactory->create();
    $resultPage->setStatusHeader(403, '1.1', 'Forbidden');
    $resultPage->addHandle('adminhtml_denied');
    return $resultPage;
}  
//...
