Displaying parse errors in module development on the browser
You have to enable error displaying in PHP. There are several ways to do it, but one of the most straightforward is to enable them in the settings.php of your project. 

Just add those lines to the file:

error_reporting(E_ALL);
$conf['error_level'] = 2;
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);


Meaning: 


Instruct PHP to notify all errors.
Instructs Drupal to show all errors (using a drupal_set_message).
Instruct PHP to display errors instead of show a blank page.
Instruct PHP to display errors even those in the startup phase.


Also, as Clive comments, if you enable XDebug error reporting is more verbose. The screenshot you show includes XDdebug error backtrace.
