State machine
=============

[](#state-machine)

The state machine is a flexible library that helps you move Eloquent models from States through Transitions while emitting events along the way.

Example
-------

[](#example)

Let's say we have a [Cat](tests/stubs/Models/Cat.php), who does two things, being

- [Asleep](tests/stubs/States/Cat/Asleep.php) and
- [Awake](tests/stubs/States/Cat/Awake.php)

In order to become Awake from his initial state being Asleep, the cat has to

- [WakeUp](tests/stubs/Transitions/Cat/WakesUp.php)

Now if we look at the [state machine definition](tests/stubs/Definitions/CatDefinition.php) we can see the above is perfectly mapped out.

Installation
------------

[](#installation)

```
composer require hyn/state-machine
```

**Read more** about installation and configuration on [state-machine.readme.io](https://state-machine.readme.io/docs).

Tests
-----

[](#tests)

Run the tests with:

```
vendor/bin/phpunit
```
