Peridot Scope

=============

[![Build Status](https://travis-ci.org/peridot-php/peridot-scope.png)](https://travis-ci.org/peridot-php/peridot-scope) [![HHVM Status](http://hhvm.h4cc.de/badge/peridot-php/peridot-scope.svg)](http://hhvm.h4cc.de/package/peridot-php/peridot-scope)

Peridot [Scope](https://github.com/peridot-php/peridot/wiki/Scopes).

Scopes allow safe binding of state for closures and offers a mechanism

for mixing state and behavior in via [child scopes](https://github.com/peridot-php/peridot/wiki/Scopes#extending-functionality-with-scopes).

Extracted from the [Peridot](http://peridot-php.github.io/) testing framework.

##Usage

We recommend installing this package via composer:

```

$ composer require peridot-php/peridot-scope:~1.0

```

###Creating a Scope

```php

$scope = new Scope();

$scope->name = "Brian";

$fnWithName = function() {

    print $this->name;

};

$fnWithName = $scope->peridotBindTo($fnWithName);

$fnWithName(); //prints "Brian"

```

###Using the ScopeTrait

If an existing class can benefit from a Scope, you can use the `ScopeTrait`

```php

class Test

{

    use ScopeTrait;

    

    protected $definition;

    

    public function __construct(callable $definition)

    {

        $this->definition = $definition; 

    }

    

    /**

     * Return the definition bound to a scope

     */

    public function getDefinition()

    {

        $scope = $this->getScope();

        return $scope->peridotBindTo($this->definition);

    }

}

```

##Mixins

You can mix behavior in via [child scopes](https://github.com/peridot-php/peridot/wiki/Scopes#extending-functionality-with-scopes).
