How do I get a URL variable in a template?
Ok nevermind. On the other stack I mentioned the function was

function riptide7_preprocess_page_title(&amp;$variables) {
  $variables['url'] = $_SERVER['REQUEST_URI'];
  $variables['#cache']['contexts'][] = 'url.path';
    echo "What?!";
}


and I just had to change preprocess_page_title to preprocess_page
