Minimal PHP Code Causing Issue

See https://getrector.org/demo/224e1a17-d4f4-4d71-bafe-f1d4cf129846

<?php

final class DemoFile extends Demo
{
    /**
     * @var int
     */
    private $test = 5;

    public function run()
    {
        $demo = new Demo();
        return 5;

        // we never get here
        return 10;
    }
}

final class Demo {
}

final class Demo2 {
}

Responsible rules

<?php

use Rector\Config\RectorConfig;
use Rector\Php74\Rector\Property\TypedPropertyRector;
use Rector\Set\ValueObject\SetList;
use Rector\Renaming\Rector\Name\RenameClassRector;
use Rector\DeadCode\Rector\Stmt\RemoveUnreachableStatementRector;

return static function (RectorConfig $rectorConfig): void {
    $rectorConfig->skip([
        TypedPropertyRector::class => ['/*'], 
        RenameClassRector::class => ['/*']
    ]);

    $rectorConfig->rule(TypedPropertyRector::class);
    $rectorConfig->rule(RemoveUnreachableStatementRector::class);
    $rectorConfig->ruleWithConfiguration(RenameClassRector::class, [
        Demo::class => Demo2::class,
    ]);
};

Expected Behavior

Rector should skip RenameClassRector rule (same as TypedPropertyRector was skipped)

[samsonasik]

The change is expected, the extends Demo not changed because it is final class, if the class is not final, it will change extends and new instantion, ref :

if you want to skip the RenameClassRector, you can do skip it with provide correct path:

    $rectorConfig->skip([
        RenameClassRector::class => __DIR__ . '/app/Entity'
    ]);

Thanks for the reply.

The problem is that I want to skip RenameClassRector rule, but event I provide a full path to the file, it isn't skipped:

RenameClassRector seems use post rector, which skip by path may overlapped, if you don't need, you can skip it entirely without path:

$rectorConfig->skip([ RenameClassRector::class,

//...

]);

Skipping the RenameClassRector rule is not a solution.

I want to rename class in every file except the single one. How can I achieve this ?

[TomasVotruba]

See README: https://github.com/rectorphp/rector/blob/main/docs/how_to_ignore_rule_or_paths.md

[samsonasik]

It seems not possible, as now, as it applied in post rector as well, see ClassRenamingPostRector

https://github.com/rectorphp/rector/blob/dbe8618a4c26d574ff4b457a6e853514afe90bc5/packages/PostRector/Rector/ClassRenamingPostRector.php#L35-L39

that's executed if $this->renamedClassesDataCollector->getOldToNewClasses() not empty.

The question is why you're doing that, because changing only in specific file for RenameClassRector seems not right, because when class used, it will point different object.

[grandmaster44]

I discovered that I can skip the rule by combination of two rules (RenameClassRector and ClassRenamingPostRector)

https://getrector.org/demo/acfd37ce-819f-4248-b13c-e229c438cfa7

<?php

use Rector\Config\RectorConfig;
use Rector\Php74\Rector\Property\TypedPropertyRector;
use Rector\Set\ValueObject\SetList;
use Rector\Renaming\Rector\Name\RenameClassRector;
use Rector\DeadCode\Rector\Stmt\RemoveUnreachableStatementRector;
use Rector\PostRector\Rector\ClassRenamingPostRector;

return static function (RectorConfig $rectorConfig): void {
    $rectorConfig->skip([
        TypedPropertyRector::class => ['/rector_analyzed_file.php'],
        RenameClassRector::class => ['/rector_analyzed_file.php'],
        ClassRenamingPostRector::class => ['/rector_analyzed_file.php'],
    ]);

    $rectorConfig->rule(TypedPropertyRector::class);
    $rectorConfig->rule(RemoveUnreachableStatementRector::class);
    $rectorConfig->ruleWithConfiguration(RenameClassRector::class, [
        Demo::class => Demo2::class,
    ]);
};

The reason for skipping a single file from RenameClassRector rule may be that I want to force the usage of NewMailer in new features and thus allow OldMailer to be used in old ones.

Old Feature (skip class rename):

//@deprecated
final class DeprecatedVendorMailer{}

//@deprecated
final class OldSendMailService {
    public function __construct(DeprecatedVendorMailer $mailer) {}
}

New Feature (check that NewMailer has been used - if not - rename class - from DeprecatedVendorMailer to NewVendorMailer):

final class NewVendorMailer{}

final class NewSendMailService {
    public function __construct(NewVendorMailer $mailer) {}
}

@grandmaster44 awesome 👍 , yes, it seems skip both RenameClassRector and ClassRenamingPostRector seems the way to go as they share the $this->renamedClassesDataCollector->getOldToNewClasses() data

[samsonasik]

Re-open, I will create PR to properly fix it.
