Sometimes, we want to apply just one rule at a time. But modifying rector.php config over and over again is tedious and can lead to mistakes.
To run single rule, we can use --only CLI option. Just add quoted class name:
vendor/bin/rector --only="Rector\DeadCode\Rector\ClassMethod\RemoveUnusedPrivateMethodRector"
Mind the quotes, as both Win and *nix system require them to pick up the full class name string (both single and double are supported).
rector.php#We can run only the rules explicitly registered in rector.php or loaded sets. This way configured rules load explicit configuration the same way we would run the rule by calling vendor/bin/rector.
In case Rector is not able to pick up your class name, see feature pull-request that describes all supported formats.
