Primarily Drupal hooks and global API functions to manipulate views.

Code

function views_preprocess_html(&$variables) {

  // If the page contains a view as its main content, contextual links may have
  // been attached to the page as a whole; for example, by views_page_alter().
  // This allows them to be associated with the page and rendered by default
  // next to the page title (which we want). However, it also causes the
  // Contextual Links module to treat the wrapper for the entire page (i.e.,
  // the <body> tag) as the HTML element that these contextual links are
  // associated with. This we don't want; for better visual highlighting, we
  // prefer a smaller region to be chosen. The region we prefer differs from
  // theme to theme and depends on the details of the theme's markup in
  // page.tpl.php, so we can only find it using JavaScript. We therefore remove
  // the "contextual-region" class from the <body> tag here and add
  // JavaScript that will insert it back in the correct place.
  if (!empty($variables['page']['#views_contextual_links_info'])) {
    $key = array_search('contextual-region', $variables['attributes']['class']
      ->value());
    if ($key !== FALSE) {
      unset($variables['attributes']['class'][$key]);

      // Add the JavaScript, with a group and weight such that it will run
      // before modules/contextual/contextual.js.
