Patternlab php not working with PHP 8.0

[drcobel]

We use Patternlab PHP together with Azure, so the compilation is done on an Azure Ubuntu or Mac agent. They were recently updated by MS to run PHP 8.0 and Patternlab stopped working. This is the error message we get:

`Running "shell:patternlab" (shell) task Warning: Command failed: php core/console -gp PHP Fatal error: Uncaught Error: Class "\PatternLabListener" not found in /home/vsts/work/1/s/pattern-lab/vendor/pattern-lab/core/src/PatternLab/Dispatcher.php:61 Stack trace:

Bump.

We have a similar issue. We us the PHP flavor with Drupal and WordPress and we desperately need php8 support asap.

Check your configuration registration. I had to make two changes:

config/listeners.json

- {"listeners":["\\aleksip\\DataTransformPlugin\\PatternLabListener","\\PatternLab\\TwigNamespaces\\PatternLabListener","\\PatternLabListener"]} 
+ {"listeners":["\\aleksip\\DataTransformPlugin\\PatternLabListener","\\PatternLab\\TwigNamespaces\\PatternLabListener","\\PatternLab\\Listener"]}

config/patternengines.json

- {"patternengines":["\\PatternLab\\PatternEngine\\Twig\\PatternEngineRule","\\PatternEngineRule"]} 
+ {"patternengines":["\\PatternLab\\PatternEngine\\Twig\\PatternEngineRule","\\PatternLab\\PatternEngine\\Rule"]}

And I think this repository is deprecated.... See https://github.com/pattern-lab/patternlab-php-core/issues/177
