Scopes for function binding and mixins

Peridot Scope

, _(*1)

Peridot Scope., _(*2)

Scopes allow safe binding of state for closures and offers a mechanism for mixing state and behavior in via child scopes., _(*3)

Extracted from the Peridot testing framework., _(*4)

Usage

We recommend installing this package via composer:, _(*5)

$ 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, _(*6)

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., _(*7)
