  /** * Sets the "is-active" class on relevant links. * * This is a PHP implementation of the drupal.active-link JavaScript library. * * @param string $html_markup * The HTML markup to update. * @param string $current_path * The system path of the currently active page. * @param bool $is_front * Whether the current page is the front page (which implies the current * path might also be <front>). * @param string $url_language * The language code of the current URL. * @param array $query * The query string for the current URL. * * @return string * The updated HTML markup. * * @todo Once a future version of PHP supports parsing HTML5 properly * (i.e. doesn't fail on * https://www.drupal.org/comment/7938201#comment-7938201) then we can get * rid of this manual parsing and use DOMDocument instead. */
