D3I
===

[](#d3i)

D3I (Dynamic Decorator Dependency Injection) is a replacement of Pimple which I suggest to use for Silex-alike frameworks.

Main Definitions
================

[](#main-definitions)

Container
---------

[](#container)

The Container objects are for keeping services and other values (eg. configuration setting values). You can access for all values by using property access (arrow-style: `->key`) and array item access (brackets-style: `[key]`).

When you accessing an item as a property and its a Provider, the provider will be called and you will give its service:

```
$container = new Container();
$container->my_service = Provider::Create(function(Container $c) {...return $service;})->share(); // registering a service
$service = $container->my_service; // getting the unique instance of the "my_service" service
```

Provider
--------

[](#provider)

This is for encapsulating a service to be registered. You can get, share, protect, or extend a service by using this class.

Getting a service:

```
$service = $provider($container);
```

Sharing a service:

```
$provider->share();
```

Protecting a service will always returning a new instance of a service when getting from container:

```
$provider->protect();
```

Extending a service:

```
$extendedProvider = $provider->extend(function(Container $c, $s) {
	// ...using of parent container
	$foo = $c['foo'] + 1;
	// ...using of parent service
	$s->setFoo($foo);
	return $s;
});
```

...or using a provider extension:

```
$container->my_extension = Provider::Create(function(Container $c, $s=null) {
	// checking whether if extending a service or not:
	if ($s === null) return new Service(); // returning a simple service rather than extending it

	// ...using of parent container
	$foo = $c['foo'] + 1;
	// ...using of parent service
	$s->setFoo($foo);
	return $s; // returns the extended service
})->share();
...
$extendedProvider = $container['my_service']->extend($container['my_extension']);
```

This last way of extending is useful when you want to use an extension as a standalone service too.

Query Parser
------------

[](#query-parser)

D3I uses a special accessing style, let we call as *D3I queries*. You can use it by both property and array access but we suggest to use it only by array access.

By D3I queries you can access to sub-items by using a single-line query as a container key, without the need of accessing it by level to level. Useful when you want to refer to services or settings in a setting and want to access to the referred item quickly.

For example, let we have a configuration setting, creating a service based on the setting, and accessing a setting by using a D3I query:

```
$container = Container::Create([
	'my_service'	=> [
		'settings'	=> [
			'welcome_str' => 'Hello %s!'
		]
	]
]);

class MyService {
	public $settings;
	function __construct($settings) {
		$this->settings = $settings;
	}
	function getWelcome($to = 'World') {
		// getting the welcome_str property by querying service
		return sprintf($container['@my_service.settings.welcome_str'], $to);
	}
}

$container->my_service = Provider::Create(function(Container $c) {
	// getting original settings by accessing the mutated original value of this provider
	return new MyService($c['!my_service.settings']);
})
	->mutate($container['my_service']) // mutate the original value before of overlapping it
	->share();

echo $container->my_service->getWelcome();
// -> "Hello World!"
```

You can also use "#" (hash mark) for annotate an integer key of an array.
