Hi rector team! Is there a rector rule to remove named arguments

[alexandreelise]

Here the thing.
I have a project which is on PHP8.3 but I mistakenly added named arguments everywhere and I don't want to manually remove them since it's error prone and hugely ineffective. That's when your super tool rector comes in. Is there a rule to remove something like this $this->world(name: 'hello') . I want to remove the name: part which is a feature of PHP8.0 anywhere in the PHP codebase.
Could you please point me at least to the right direction?

I think I found it. I used your rector playground to try it out.

<?php

final class DemoFile
{
    public function run(bool $param)
    {
        if ($this->isTrue(value: $param)) {
            return 5;
        }

        return '10';
    }

    private function isTrue($value)
    {
        return $value === true;
    }
}

and the config is

<?php

use Rector\Config\RectorConfig;
use Rector\ValueObject\PhpVersion;
use Rector\Set\ValueObject\DowngradeLevelSetList;

return RectorConfig::configure()
    ->withPhpVersion(PhpVersion::PHP_83)
    ->withSets([DowngradeLevelSetList::DOWN_TO_PHP_74]);

I don't know if it's the best practice but in the playground it seem to work. It removes the named arguments.

Please confirm if it's the right way to do it @TomasVotruba . Enjoy your day.

Maybe that might be more relevant

https://github.com/rectorphp/rector-downgrade-php/blob/6dba10960d71bdd442b5ebe54dbbf2c4a72b263d/config/set/downgrade-php80.php#L29C1-L29C74

So the latest config file might look like

<?php

use Rector\Config\RectorConfig;
use Rector\ValueObject\PhpVersion;
use Rector\DowngradePhp80\Rector\MethodCall\DowngradeNamedArgumentRector;

return RectorConfig::configure()
    ->withPhpVersion(PhpVersion::PHP_83)
    ->withRules([DowngradeNamedArgumentRector::class]);

Is it better?

Hope it helps someone that stumbled upon the same hurdle.

Your rector playground is definitely a game changer. Super useful tool to grasp more easily and visually the TRUE POWER of rector. Nice! Have a delightful day rector team. I think I figured it out thanks to your playground. Won't waste your precious time. Take care...
