Move base theme system templates into /core/templates

Created on 1 February 2013, over 12 years ago

Problem/Motivation

This issue was originally about providing for theme templates that would represent theme callbacks used in .inc files. However, drupal_common_theme() is only ever called once, by system_theme(). We could move drupal_common_theme() directly into system_theme(), and then all the theme functions/templates there too. All the places where these functions are used without a full bootstrap currently have to include system module beforehand.

Once they're in system module, there's incentive to factor them back out again.

Original issue by steveoliver

Drupal currently has no way of supporting templates for theme implementations defined in core/includes/* except by searching in themes/ directories drupal_find_theme_templates.

In our effort to replace Drupal's theme functions with [Twig] templates, we need a way for the theme system to find templates for theme implementations in /core/includes/.

Thank you for creating this issue to improve Drupal.

We are working to decide if this task is still relevant to a currently supported version of Drupal. There hasn't been any discussion here for over 8 years which suggests that this has either been implemented or is no longer relevant. Your thoughts on this will allow a decision to be made.

Since we need more information to move forward with this issue, the status is now Postponed (maintainer needs more info). If we don't receive additional information to help with the issue, it may be closed after three months.

Thanks!
