Finalize classes in a safe way. We first look for those, that should be skipped:

• classes who are in parent position
• Doctrine entities by docblocks and attribute

composer require tomasvotruba/finalize --dev

1. First run command, that detects parent classes, entities etc.

vendor/bin/finalize detect src/ tests/

It will generate .finalize.json files with all found classes, that should be skipped.

2. Run Rector with config that contains TomasVotruba\Finalize\Rector\FinalizeClassRector rule.

Rector uses data from .finalize.json to keep used classes non final and finalize only the safe ones:

vendor/bin/rector process --config vendor/tomasvotruba/finalize/config/prepared-rector.php

Do not keep this run in your main rector.php. Family map can change with any new class, e.g. some new class will come and it will be extended, and Rector would not finalize valid class.
