DIC-IT is a simple dependency injection container, with extensible activation & injection strategies.

Setup
-----

[](#setup)

The recommended setup is to create a config folder at the root of your repository. All configuration is based on YAML files.

Sample YAML file :

```
parameters:
    MyParameter: 'Some parameter value'
    MyOtherParameter: 42
    MyParameters:
        nested_level:
            foo : foo
            bar : bar
            baz : foobar
classes:
    MyServiceName:
        class: \Fully\Qualified\ClassName
        arguments: [ @MyDependency, %MyParameter, %MyParameters.nested_level, 'Hard-coded value', $container, $env.ENV, $const.ROOT_PATH ]
    MyDependency:
        class: \Fully\Qualified\DependencyClassName
        props:
            MyProperty: %MyOtherParameter

```

References
----------

[](#references)

You can inject different kind of references inside class definitions. You can get other service instances, parameters, the container itself, env variables, and constant values.

- @ServiceName : fetch an instance of that definition
- %param : fetch a parameter defined in the container
- $container : fetch the container itself
- $env.ENV\_NAME : fetch an environment variable
- $const.CONST\_NAME : fetch a global defined constant value

Using includes
--------------

[](#using-includes)

The configuration can be split into multiple files to ease management of your dependencies :

```
includes:
    - relative/file.yml
    - relative/another-file.yml

classes:
    ...

```

This allows you to separate parameters from service definitions for example.

Default object life-cycle
-------------------------

[](#default-object-life-cycle)

By default, all objects are created as non-singleton (this will definitely change) objects, so every time a reference is resolved by the container, a new instance of the requested object is created.

Managing circular dependencies
------------------------------

[](#managing-circular-dependencies)

By default, circular dependencies are not handled well (stack overflow...) due the default object life-cycle. To enable circular dependencies for a given object, at least one of the two objects must be defined as a singleton. This however will not yield the expected results, so it is *highly* recommended to define both objects involved in the circular dependency as singletons.
