Usage

Once the extension is installed, simply modify your application configuration as follows:

return [
    'bootstrap' => ['debug'],
    'modules' => [
        'debug' => [
            'class' => Yiisoft\Yii\Debug\Module::class,
            // uncomment and adjust the following to add your IP if you are not connecting from localhost.
            //'allowedIPs' => ['127.0.0.1', '::1'],
        ],
        // ...
    ],
    ...
];

You will see a debugger toolbar showing at the bottom of every page of your application. You can click on the toolbar to see more detailed debug information.

Open Files in IDE

You can create a link to open files in your favorite IDE with this configuration:

return [
    'bootstrap' => ['debug'],
    'modules' => [
        'debug' => [
            'class' => Yiisoft\Yii\Debug\Module::class,
            'traceLine' => '<a href="phpstorm://open?url={file}&line={line}">{file}:{line}</a>',
            // uncomment and adjust the following to add your IP if you are not connecting from localhost.
            //'allowedIPs' => ['127.0.0.1', '::1'],
        ],
        // ...
    ],
    ...
];

You must make some changes to your OS. See these examples:

Virtualized or dockerized

If your application is run under a virtualized or dockerized environment, it is often the case that the application's base path is different inside of the virtual machine or container than on your host machine. For the links work in those situations, you can configure traceLine like this (change the path to your app):

'traceLine' => function($options, $panel) {
    $filePath = str_replace($this->app->basePath, '~/path/to/your/app', $options['file']);
    return strtr('<a href="ide://open?url=file://{file}&line={line}">{text}</a>', ['{file}' => $filePath]);
},
