# GenStateMachine

An idiomatic Elixir wrapper for `gen_statem` in OTP 19 (and above).

**Full documentation is available [here](**

**You can find the package on Hex [here](**

One important difference between `gen_statem` and this wrapper is that you
declare your callback mode as part of `use GenStateMachine` in this wrapper,
rather than returning it from your `init/1` and `code_change/4`. You can still,
however, switch callback modes in `code_change/4` by returning a callback mode.

Other than that (and the usual automatically-defined default callbacks as a
result of `use`-ing `GenStateMachine`), this wrapper does not make any
functional alterations.

## Installation

  1. Add `gen_state_machine` to your list of dependencies in `mix.exs`:

    def deps do
      [{:gen_state_machine, "~> 0.0.2"}]

  2. Ensure `gen_state_machine` is added to your applications:

    def application do
      [applications: [:gen_state_machine]]
