Replaces variable values in included names with configuration data.

Variable values are nested configuration keys that will be replaced by their value or some of these special strings:

• '%key', will be replaced by the element's key.
• '%parent', to reference the parent element.

There may be nested configuration keys separated by dots or more complex patterns like '%parent.name' which references the 'name' value of the parent element.

Example patterns:

• 'name.subkey', indicates a nested value of the current element.
• '%parent.name', will be replaced by the 'name' value of the parent.
• '%parent.%key', will be replaced by the parent element's key.

Based on Drupal\Core\Config\TypedConfigManager::replaceVariable($value, $data).

Parameters

string $value: Variable value to be replaced.

mixed $data: Configuration data for the element.

Return value

string The replaced value if a replacement found or the original value if not.
