General State Machine for Elixir

Using Statex is easy, you just have to define a @state_graph.

  defmodule LightSwitch do
    use Statex

    @state_graph off: [flip: :on],
                 on:  [flip: :off]

  end

  iex> {:ok, pid} = LightSwitch.start_link()
  ...
  iex> LightSwitch.state(pid)
  :off
  iex> LightSwitch.flip(pid)
  :ok
  iex> LightSwitch.state(pid)
  :on
  iex> LightSwitch.flip(pid)
  :ok
  iex> LightSwitch.state(pid)
  :off

Installation

The package can be installed by adding Statex to your list of dependencies in mix.exs:
