property path format

[root-aza]

Hi! Is it possible to somehow change the formation of the property path?

Example:

 cities.0.name => cities.[0].name

Hi @root-aza, pinging me wont change the delay for the answer that I write during my sparetime, and is kind of a rude thing to do after such a short time. Please be careful about it 😉

Concerning your question, I don't really understand what is needed there: could you add a more detailed example of what should be changed?

Code example

<?php

declare(strict_types=1);

use CuyZ\Valinor\Mapper\MappingError;
use CuyZ\Valinor\Mapper\Source\Source;
use CuyZ\Valinor\Mapper\Tree\Message\Messages;
use Symfony\Component\Validator\ConstraintViolation;
use Symfony\Component\Validator\ConstraintViolationList;

include 'vendor/autoload.php';


final readonly class Country
{
    /**
     * @param non-empty-string $name
     * @param list<City>       $cities
     */
    public function __construct(
        public string $name,
        public array $cities,
    ) {}
}

final readonly class City
{
    /**
     * @param non-empty-string       $name
     * @param DateTimeZone $timeZone
     */
    public function __construct(
        public string $name,
        public DateTimeZone $timeZone,
    ) {}
}

$json = <<<JSON
    {
        "cities": [
            {"name": "", "timeZone": "Europe/Paris"},
            {"name": "Lyon", "timeZone": "Europe/Paris"}
        ]
    }
JSON;

try {
    $country = (new \CuyZ\Valinor\MapperBuilder())
        ->mapper()
        ->map(Country::class, Source::json($json));

    echo $country->name; // France
    echo $country->cities[0]->name; // Paris
} catch (MappingError $error) {
    $list = new ConstraintViolationList();

    foreach (Messages::flattenFromNode($error->node())->errors() as $error){
        $node    = $error->node();
        $newPath = $node->path();

        $constraint = new ConstraintViolation(
            $error->toString(),
            messageTemplate: null,
            parameters: [],
            root: null,
            propertyPath: $node->path(),
            invalidValue: $node->sourceFilled() ? $node->sourceValue() : null,
            code: '72fb6435-c397-4dd2-a201-94c6b4973157'
        );


        $list->add($constraint);
    }
}

$node->path() returns a path like cities.0.name

but we want to get cities.[0].name

Why is this necessary?
To comply with the contract

If I understand correctly, this is needed by the ConstraintViolation class? Is there any documentation I can read about that?

not really.

symfony/validator initially generates a path in the format cities.[0].name

And I would like monotony
