Configurations off-canvas: styles list validation

riabovol → closed merge request !19

A good example of the entity constraint implementation https://www.drupal.org/docs/drupal-apis/entity-api/entity-validation-api... →

@riabovol here an example of validation with good regexp

    $styles = ".in_circle|Tes\r\n.in-circle|tes12\r\n.incircle|as12\r\n.in_circle|In Circle\r\n.bordered|With Borders\r\n.some-example|SomeExample\r\n123text|123Test\r\n\sad|\Sad\r\n.some_class*|someclass\r\n";

    $styles = str_replace(["\r\n", "\r"], "\n", $styles);
    foreach (explode("\n", $styles) as $style) {
      $style = trim($style);

      // Validate syntax: [.class...]|label pattern expected.
      if (!preg_match('@^ *(\\.[_a-zA-Z]+[a-zA-Z0-9_-]+ *)*\\| *.+ *$@', $style)) {
        return FALSE;
      }

      // Parse.
      [$selector, $label] = explode('|', $style);
      $configured_style = [
        'name' => trim($label),
        'class' => trim($selector),
      ];

    }

MR looks fine, merging it into the dev branch.
