Peridot Scope.

Scopes allow safe binding of state for closures and offers a mechanism for mixing state and behavior in via child scopes.

Extracted from the Peridot testing framework.

##Usage

We recommend installing this package via composer:

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

###Creating a Scope

$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

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.
