When I run the script it errors out

PHP Fatal error: Uncaught Error: Call to a member function getType() on string in DesignPatternDetector/vendor/phpmetrics/phpmetrics/src/Hal/Component/OOP/Extractor/Extractor.php:89

I am having the same issue.

Guys, you need to start script by executing next:
./vendor/bin/phpmetrics <path-to-your-code>

[vukanac]

That command does not produce expected output about used design patterns.
It should be something like:
$ ./bin/design-pattern /projects/project/src/

[vukanac]

With hope to re-alive this repo, I tried to upgrade required libs to the latest, and fix 3 bugs (similar) but have the new one:

Extracting classes
  0/27 [>---------------------------]   0%

  [Symfony\Component\Debug\Exception\FatalThrowableError]
  Class 'Hal\Component\Token\Tokenizer' not found

From phpmetrics Tokenizer is removed.

If someone can say or help with what to change Tokenizer.
