In a recent project I discovered a major WTF in the theme hook suggestions. Perhaps someone could clarify this.
I needed to distiguish between views block and views page and added the following hook:
/**
* Implements hook_theme_suggestions_HOOK_alter() for node templates.
*/
function MY_THEME_theme_suggestions_views_view_alter(array &$suggestions, array $variables) {
$view = $variables['view'];
$suggestions[] = 'views__' . $view->getDisplay()->getBaseId();
}This ends up in the following suggestions:
<!-- FILE NAME SUGGESTIONS:
* views--block.html.twig
x views-view.html.twig
-->I added the template called views--block.html.twig but the template does not get discovered.
The theme system still uses views-view.html.twig.
Now the WTF:
If i rename the file from views--block.html.twig to views-view--block.html.twig there are new suggestions added without changing the preprocess function:
<!-- FILE NAME SUGGESTIONS:
x views-view--block.html.twig
* views--block.html.twig
x views-view--block.html.twig
* views-view.html.twig
-->And now it works. For me this is not understandable, could someone explain this to me ?
