render.inc Provides hooks and theme callbacks for default render hooks. @TODO add a "sprite" render hook.

Code

function icon_preprocess_icon_sprite(&$variables) {
  $bundle =& $variables['bundle'];
  $icon =& $variables['icon'];

  // Add default settings.
  if (!isset($bundle['settings']['tag'])) {
    $bundle['settings']['tag'] = 'span';
  }
  if (!isset($bundle['settings']['content'])) {
    $bundle['settings']['content'] = '';
  }

  // Sanitize and add icon class here. Don't need to check for numeric because
  // these are already CSS class name based.
  $variables['attributes']['class'][] = \Drupal\Component\Utility\Html::getClass($icon);
}
