editor

When your debug mode is enabled, you can set your editor to quickly open the file in which the error appeared.

return [
    'debug'  => true,
    'editor' => 'vscode'
];

The following editors are supported:

Make sure to disable debug mode in production! Displaying PHP errors on a public server can be a serious security risk:

Error messages are displayed with detailed information about the code structure (e.g. file path, class, method)
With Whoops enabled, there will be even more detailed information about the code structure

In a production environment, always log errors to your PHP error logs.
