<?php

<?= $this->wysiwyg('content', \AppBundle\Document\EditableConstants::BLOG_WYSIWYG_CONFIG); ?>

Extend by using

<?= $this->wysiwyg('content', \AppBundle\Document\EditableConstants::extend(
    \AppBundle\Document\EditableConstants::BLOG_WYSIWYG_CONFIG, [
    // your extra config goes here
]
)); ?>

Use this PHP class for using the class EditableConstants with Twig:

<?php

declare(strict_types=1);

namespace AppBundle\Twig;

use AppBundle\Document\EditableConstants;
use Twig\TwigFunction;
use Twig\Extension\AbstractExtension;

class WYSIWYGEditablesExtension extends AbstractExtension
{
    /**
     * {@inheritdoc}
     */
    public function getFunctions()
    {
        return [
            new TwigFunction('wysiwyg_config', function (string $constant) {
                return constant(EditableConstants::class . '::' . $constant);
            }),
        ];
    }
}

Usage:

{{ dump(wysiwyg_config('TITLE_WYSIWYG_CONFIG')) }}

(Don't forgot to register it within templating_twig.yml)
