I cannot find the list in the api documentation.
https://api.drupal.org/api/drupal/core%21modules%21views%21views.api.php/group/views_hooks/8.5.x
Nor am I able to enter such functions in a theme when loading a page with a view.
They're here
- In the codebase: core/modules/views/views.api.php.
- On the web: https://api.drupal.org/api/drupal/core%21modules%21views%21views.api.php/8.5.x
As always, only *_alter hooks and hook_theme can be implemented in a theme. Any other hook needs to be implemented in a module.
