Load app configuration based on a PHP / YAML tree

[gorkalaucirica]

Based on the usage of WPFoundation done in the latest projects I see that mainly configuration related things are done.

My proposal is to generate a config tree using PHP (maybe a YAML alternative could be used also, but might be limited).

Example of a basic configuration tree:

class Config
{
    const MENU_MAIN = 'Main menu';
    const VENDOR_PATH = '';

    const POST_TYPE_EXHIBITION = 'exhibition';
    const POST_TYPE_PAGE = 'page';

    const TAXONOMY_EXHIBITION_CATEGORY = 'exhibition_category';

    const TEMPLATE_PAGE_CONTACT = 'page_contact';
    const TEMPLATE_PAGE_FRONT_PAGE = 'front_page';
    const TEMPLATE_PAGE_GENERIC = 'generic';
}

$baseOptions = [
    'has_archive'        => true,
    'public'             => true,
    'publicly_queryable' => true,
    'query_var'          => true,
    'show_in_rest'       => true,
    'show_ui'            => true,
];

$config = [
    'logo'       => get_stylesheet_directory_uri() . '/../../themes/app/assets/images/site-login-logo.png',
    'menus'      => [
        Config::MENU_MAIN => Translations::trans('Main menu'),
    ],
    'assets'     => [
        'jquery.sidr.min' => [
            'path'         => Config::VENDOR_PATH . '/sidr',
            'dependencies' => [],
            'version'      => '1.0.0',
            'media'        => 'all'
        ]
    ],
    'templates'  => [
        'front_page'   => Translations::trans('Front Page'),
        'page_contact' => Translations::trans('Contact'),
        'Generic'      => Translations::trans('Generic (Page builder)'),
    ],
    'post_types' => [
        Config::POST_TYPE_EXHIBITION => array_merge($baseOptions, [
            'labels'   => [
                'name'          => Translations::trans('Exhibitions'),
                'singular_name' => Translations::trans('Exhibition'),
            ],
            'supports' => ['title', 'editor', 'thumbnail'],
        ])
    ],
    'fields' => [
        [
            'fields' => [ExhibitionPostFields::class],
            'connector' => new PostTypeFieldConnector(Config::POST_TYPE_EXHIBITION)
        ]
    ]
];
