Check all pages

A script that validates the content of all pages against their blueprints:

<?php // bin/check-content.php
use Blueprint\App;
use Blueprint\Config;
use Blueprint\Page;

define("PROJECT_DIR", dirname(__DIR__));
require PROJECT_DIR . "/vendor/autoload.php";

App::create(Config::load(PROJECT_DIR . "/config"));

$check = function (iterable $pages) use (&$check) {
    foreach ($pages as $page) {
        foreach ($page->blueprint()->validate($page->data()) as $field => $messages) {
            echo $page->id(), " › $field: ", implode(", ", $messages), PHP_EOL;
        }
        $check($page->allChildren());
    }
};

$check(site()->allChildren());
