AddNamedArgumentsRector

The AddNamedArgumentsRector rule enhances your code by converting function, method, or constructor calls to use named arguments where possible. Named arguments improve readability and reduce errors by explicitly naming the parameters being passed.

Example

- str_contains('foo', 'bar');
+ str_contains(haystack: 'foo', needle: 'bar');

This feature works for:

• Functions
• Static methods
• Instance methods
• Constructors

---

Installation

You can install the package via Composer:

composer require --dev savinmikhail/add_named_arguments_rector

---

Usage

To enable the rule, add it to your Rector configuration (rector.php):

<?php

declare(strict_types=1);

use Rector\Config\RectorConfig;
use SavinMikhail\AddNamedArgumentsRector\AddNamedArgumentsRector;

return static function (RectorConfig $rectorConfig): void {
    $rectorConfig->rule(AddNamedArgumentsRector::class);
};

---

Customization

By default, the rule applies named arguments universally where possible. However, if you want more control over when the rule applies, you can use a strategy:

<?php

declare(strict_types=1);

use Rector\Config\RectorConfig;
use SavinMikhail\AddNamedArgumentsRector\AddNamedArgumentsRector;
use SavinMikhail\AddNamedArgumentsRector\Config\PhpyhStrategy;

return static function (RectorConfig $rectorConfig): void {
    $rectorConfig->ruleWithConfiguration(
        AddNamedArgumentsRector::class,
        [PhpyhStrategy::class]
    );
};

Implementing Your Own Strategy

See PhpyhStrategy as example, you can create your own strategy by implementing the ConfigStrategy interface. For example:

<?php

declare(strict_types=1);

namespace YourNamespace;

use PhpParser\Node;
use SavinMikhail\AddNamedArgumentsRector\Config\ConfigStrategy;

class CustomStrategy implements ConfigStrategy
{
    public static function shouldApply(Node $node, array $parameters): bool
    {
        // Add your custom logic here
        return true;
    }
}

Then, configure it in your rector.php:

<?php

declare(strict_types=1);

use Rector\Config\RectorConfig;
use SavinMikhail\AddNamedArgumentsRector\AddNamedArgumentsRector;
use YourNamespace\CustomStrategy;

return static function (RectorConfig $rectorConfig): void {
    $rectorConfig->ruleWithConfiguration(
        AddNamedArgumentsRector::class,
        [CustomStrategy::class]
    );
};
