Problem/Motivation

There are far, far too many ways to do exactly the same thing in Drupal. In particular, there are 4 ways to provide theme_hook_suggestions for Drupal 8:

  1. provide a pattern in hook_theme
  2. implement hook_template_suggestions()
  3. implement hook_template_suggestions_alter()
  4. pass an array to theme()

Proposed resolution

If we were to remove pattern from hook_theme, there would only be three ways to do the same thing.

From the API:

pattern: A regular expression pattern to be used to allow this theme implementation to have a dynamic name. The convention is to use __ to differentiate the dynamic portion of the theme.

For all current uses of 'pattern' in core we should use hook_template_suggestions() instead.

Remaining tasks

Remove pattern from hook_theme().

User interface changes

None.

API changes

Remove pattern from hook_theme().

#1751194: Introduce hook_theme_suggestions[_HOOK]() and hook_theme_suggestions[_HOOK]_alter()

We just removed these from Views, but with the expectation that $hook . '__' would always be added.

So we could just have a global one that does $hook . '__' for each hook...

Postponed until we can actually do this.

The idea is that the pattern is removed as an external option, but kept as an internal option.

Already now theme:8 has the assumption that the pattern is '__', so we would keep that, but purely internally.

So as core already has the pattern hardcoded for the case, where it does not _know_ the hook to use the pattern from, it makes sense to remove the 'pattern' option entirely from hook_theme() and hardcode to '__' everywhere.

Thanks!

I guess this could be done at some point in Drupal 8 release cycle because the pattern doesn't work anymore.
