Throw exception if Phar not installed

[ghost]

With Couscous:

https://github.com/CouscousPHP/Couscous

if Phar is not installed you get this:

The "phar" extension is required to run this archive.

but with Spress you get nothing. I checked the code and here is the difference:

if (class_exists('Phar')) {
   $include = 'phar://' . __FILE__;
   Phar::mapPhar('couscous.phar');
} else {
   throw new Exception('The "phar" extension is required to run this archive.');
}

if (class_exists('Phar')) {
   Phar::mapPhar('spress.phar');
   require 'phar://' . __FILE__ . '/bin/spress';
}

Yes. I'm gonna add that exception

Where did you see these lines of code?

if (class_exists('Phar')) {
   Phar::mapPhar('spress.phar');
   require 'phar://' . __FILE__ . '/bin/spress';
}
