The new class `\CuyZ\Valinor\Mapper\Tree\Message\MessageBuilder` can be
used to easily create an instance of (error) message.
This new straightforward way of creating messages leads to the
depreciation of `\CuyZ\Valinor\Mapper\Tree\Message\ThrowableMessage`.
```php
$message = MessageBuilder::newError('Some message / {some_parameter}.')
->withCode('some_code')
->withParameter('some_parameter', 'some_value')
->build();
```
The `MethodObjectBuilder` was incorrectly used when a registered
constructor is a static anonymous functions — it was handled like a
static method closure `Class::method(...)` and would yield errors like
this:
```
Error: Call to undefined method
stdClass::CuyZ\Valinor\Tests\Integration\Mapping\{closure}()
```
PHP Reflection does not provide any way of telling static functions and
closures of static methods apart, other than checking for the name
`{closure}`. We check that `{closure}` is actually the last part of the
fully-qualified name, instead of just checking that the string ends with
`{closure}`.
Fixes the following message reported by `symfony/error-handler`:
`User Deprecated: Method "Psr\SimpleCache\CacheInterface::get()" might
add "mixed" as a native return type declaration in the future. Do the
same in implementation "CuyZ\Valinor\Cache\..." now to avoid errors or
add an explicit @return annotation to suppress this message.`
Method `\CuyZ\Valinor\Cache\FileSystemCache::get()` was not properly
looping on all delegates, leading to the values not being fetched from
the cache files and resulting in `null` (the default value) being
returned in some cases. Because of the following algorithm, the cache
entry was populated again, so the cache was not really working here.
```php
if ($this->cache->has($key)) {
$entry = $this->cache->get($key);
if ($entry) {
return $entry;
}
}
$class = $this->delegate->for($type);
$this->cache->set($key, $class);
return $class;
```
```php
(new \CuyZ\Valinor\MapperBuilder())
// Both `Cookie` and `ATOM` formats will be accepted
->supportDateFormats(DATE_COOKIE, DATE_ATOM)
->mapper()
->map(DateTimeInterface::class, 'Monday, 08-Nov-1971 13:37:42 UTC');
```
A new constructor can be registered to declare which format(s) are
supported during the mapping of a date object. By default, any valid
timestamp or ATOM-formatted value will be accepted.
```php
(new \CuyZ\Valinor\MapperBuilder())
// Both COOKIE and ATOM formats will be accepted
->registerConstructor(
new \CuyZ\Valinor\Mapper\Object\DateTimeFormatConstructor(DATE_COOKIE, DATE_ATOM)
)
->mapper()
->map(DateTimeInterface::class, 'Monday, 08-Nov-1971 13:37:42 UTC');
```
The previously very opinionated behaviour has been removed, but can be
temporarily used to help with the migration.
```php
(new \CuyZ\Valinor\MapperBuilder())
->registerConstructor(
new \CuyZ\Valinor\Mapper\Object\BackwardCompatibilityDateTimeConstructor()
)
->mapper()
->map(DateTimeInterface::class, 'Monday, 08-Nov-1971 13:37:42 UTC');
```
In some situations the type handled by a constructor is only known at
runtime, in which case the constructor needs to know what class must be
used to instantiate the object.
For instance, an interface may declare a static constructor that is then
implemented by several child classes. One solution would be to register
the constructor for each child class, which leads to a lot of
boilerplate code and would require a new registration each time a new
child is created. Another way is to use the attribute
`\CuyZ\Valinor\Mapper\Object\DynamicConstructor`.
When a constructor uses this attribute, its first parameter must be a
string and will be filled with the name of the actual class that the
mapper needs to build when the constructor is called. Other arguments
may be added and will be mapped normally, depending on the source given
to the mapper.
```php
interface InterfaceWithStaticConstructor
{
public static function from(string $value): self;
}
final class ClassWithInheritedStaticConstructor implements InterfaceWithStaticConstructor
{
private function __construct(private SomeValueObject $value) {}
public static function from(string $value): self
{
return new self(new SomeValueObject($value));
}
}
(new \CuyZ\Valinor\MapperBuilder())
->registerConstructor(
#[\CuyZ\Valinor\Attribute\DynamicConstructor]
function (string $className, string $value): InterfaceWithStaticConstructor {
return $className::from($value);
}
)
->mapper()
->map(ClassWithInheritedStaticConstructor::class, 'foo');
```
It is now possible to register a static method constructor that can be
inherited by a child class. The constructor will then be used correctly
to map the child class.
```php
abstract class ClassWithStaticConstructor
{
public string $value;
final private function __construct(string $value)
{
$this->value = $value;
}
public static function from(string $value): static
{
return new static($value);
}
}
final class ChildClass extends ClassWithStaticConstructor {}
(new MapperBuilder())
// The constructor can be used for every child of the parent class
->registerConstructor(ClassWithStaticConstructor::from(...))
->mapper()
->map(ChildClass::class, 'foo');
```
Using two instances of the same class implementing the `__invoke()`
method in one of the mapper builder methods will now be properly handled
by the library
Handles race condition when the attribute is affected to a property or
parameter that was promoted, in this case the attribute will be applied
to both `ParameterReflection` and `PropertyReflection`, but the target
argument inside the attribute class is configured to support only one of
them (parameter or property).

The `\CuyZ\Valinor\Mapper\Tree\Message\Message` interface is no longer
a `Stringable`, however it defines a new method `body` that must return
the body of the message, which can contain placeholders that will be
replaced by parameters.
These parameters can now be defined by implementing the interface
`\CuyZ\Valinor\Mapper\Tree\Message\HasParameters`.
This leads to the deprecation of the no longer needed interface
`\CuyZ\Valinor\Mapper\Tree\Message\TranslatableMessage` which had a
confusing name.
```php
final class SomeException
extends DomainException
implements ErrorMessage, HasParameters, HasCode
{
private string $someParameter;
public function __construct(string $someParameter)
{
parent::__construct();
$this->someParameter = $someParameter;
}
public function body() : string
{
return 'Some message / {some_parameter} / {source_value}';
}
public function parameters(): array
{
return [
'some_parameter' => $this->someParameter,
];
}
public function code() : string
{
// A unique code that can help to identify the error
return 'some_unique_code';
}
}
```
The class `\CuyZ\Valinor\Mapper\Tree\Node` has been refactored to remove
access to unwanted methods that were not supposed to be part of the
public API. Below are a list of all changes:
- New methods `$node->sourceFilled()` and `$node->sourceValue()` allow
accessing the source value.
- The method `$node->value()` has been renamed to `$node->mappedValue()`
and will throw an exception if the node is not value.
- The method `$node->type()` now returns a string.
- The methods `$message->name()`, `$message->path()`, `$message->type()`
and `$message->value()` have been deprecated in favor of the new
method `$message->node()`.
- The message parameter `{original_value}` has been deprecated in favor
of `{source_value}`.
The access to class/function definition, types and exceptions did not
add value to the actual goal of the library. Keeping these features
under the public API flag causes more maintenance burden whereas
revoking their access allows more flexibility with the overall
development of the library.
This feature was a relic of the first release of the library. It had
strong design issues and was going to become a huge blocker for upcoming
features.
Although it was never documented, it may have been used in applications;
there will be no replacement for this feature. If this becomes an issue
for existing applications, an issue can be created in the repository to
discuss other possible solutions.
