[2.0.0-alpha1] Add PropTypeInterface::normalize()

Problem/Motivation

Today, each source plugin is responsible of the validity of the data returned by SourceInterface::getData(): mixed

For better safety, we need to add an extra check managed by the prop type themselves.

Proposed resolution

Add PropTypeInterface::normalize(mixed $value): mixed method and implement it in every prop type plugins.

Example for strings:

function normalize(mixed $value): mixed {
  return (string) $value;
}

This new method may be the opportunity of merging 2 over-specific mechanisms.

ComponentElementAlter::cleanSlotsValues(array $element): array

This can be moved to the new normalize() method of Slot prop type.

However, even if it will look a bit empty after the removal of cleanSlotsValues we want to keep ComponentElementAlter, because :

  • we want PropTypeInterface::normalize() to be called by ComponentElementAlter and not by ComponentElementBuilder, so every component will be normalized, even when they are not build by the ComponentElementBuilder
  • we will add other mechanisms to ComponentElementAlter later

LinksPropType::normalize(array $items): array

This method can be updated to use the new method instead of being public without being described by any interface

This method is currenly static, does that means PropTypeInterface::normalize() will be static too?

This method is currently explicitly called from preprocesses, example: 

$before = LinksPropType::normalize(\array_filter([
  $variables['items']['first'] ?? [],
  $variables['items']['previous'] ?? [],
));

But we hope than calling PropTypeInterface::normalize() from ComponentElementAlter will help remove those explicit direct calls.

Remaining tasks

There is an ongoing discussion about the naming of this method. Maybe ::sanitize() or prepare() is better.... Let's talk.

Don't hesitate to share your brainstorming with maintainers of UI Suite themes.
