[![Build Status](https://camo.githubusercontent.com/82ce695f15e07a506c307b981f497c3d20958544428fe295ae1d6c0640125209/68747470733a2f2f7472617669732d63692e6f72672f6b61796c61646e6c732f737065632e7376673f6272616e63683d6d6173746572)](https://travis-ci.org/kayladnls/spec) [![Code Climate](https://camo.githubusercontent.com/0a427af82b1e6e54f45357c1fb97a80b9edeec74acb725843a8ec8584caaae37/68747470733a2f2f636f6465636c696d6174652e636f6d2f6769746875622f6b61796c61646e6c732f737065632f6261646765732f6770612e737667)](https://codeclimate.com/github/kayladnls/spec)

### Installation

[](#installation)

```
composer require kayladnls/spec

```

### What is it?

[](#what-is-it)

> "the specification pattern is a particular software design pattern, whereby business rules can be recombined by chaining the business rules together using boolean logic. The pattern is frequently used in the context of domain-driven design." -- [wikipedia](https://en.wikipedia.org/wiki/Specification_pattern)

### How do I use it?

[](#how-do-i-use-it)

#### Use the builder

[](#use-the-builder)

```
$all_spec = Kayladnls/Spec/Builder::all(new MustHaveFourLegs(), new MustHaveStripesSpec());

$all_spec->isSatisfiedBy($elephpant) //False
$all_spec->isSatisfiedBy($zebra)     // True

$any_spec = Kayladnls/Spec/Builder::any($all_spec, new IsLizardSpec());
$any_spec->isSatisfiedBy($iguana) // True
```

Or, you can use functions if that's what tickles your fancy.

#### Function Based

[](#function-based)

```
$all_spec = Kayladnls/Spec/all([new MustHaveFourLegs(), new MustHaveStripesSpec()]);

Kayladnls/Spec/satisfies($elephpant, $all_spec) //False
Kayladnls/Spec/satisfies($zebra, $all_spec) //True

$any_spec = Kayladnls/Spec/any([$all_spec, new IsLizardSpec()]);
Kayladnls/Spec/satisfies($iguana, $any_spec) // True

$none_spec = Kayladnls/Spec/none([new MustHaveFourLegs(), new MustHaveSpotsSpec()]);
Kayladnls/Spec/satisfies($kangaroo, $none_spec) // true
Kayladnls/Spec/satisfies($cheetah, $none_spec) // false
```

### Example

[](#example)

```
if ($all_spec->isSatisfiedBy($zebra)){
	// Do Some cool Zebra Stuff here.
}

// Function Based
if (satisfies($iguana, $any_spec)){
	// do some cool lizard-based stuff here.
}
```
