I am new to drupal 8 and i need to override a views template. So, for that I have enabled theme debug in services.yml to view the twig template suggestion name.

Normal view theme debug.

<!-- THEME DEBUG -->
<!-- THEME HOOK: 'views_view_unformatted' -->
<!-- BEGIN OUTPUT from 'themes/custom/cohesion/templates/views/views-view-unformatted.html.twig' -->

This is my view theme debug when in have views-view-unformatted--test-view.html.twig in my theme.

<!-- THEME DEBUG -->
<!-- THEME HOOK: 'views_view_unformatted__test_view' -->
   x views-view-unformatted--test-view.html.twig
   x views-view-unformatted--test-view.html.twig
   * views-view-unformatted.html.twig

I used both the theme hook suggestion(preprocess) function to override in mytheme.theme file and the function calls. But inside the function the variable argument is empty inside that function. So i cant able to get the field values from my view in preprocess function.

Is there anyway to override the variables coming to the twig template. Can anyone give me suggestion to override the views template.

Views uses multiple theme hooks instead of theme suggestions. I think we should add theme hooks to twig debug similar to template suggestions.

There is test coverage for twig debug, so this would need test coverage expanded.

The issue summary needs an update to explain why this is a task and to reference the original report.

This also needs a beta evaluation, which should be easy, because twig debugging messages are markup, so this is "unfrozen".
