# GenFsm
Elixir wrapper around Erlang's OTP gen_fsm.
## Motivation
Elixir [deprecated](https://github.com/elixir-lang/elixir/commit/455eb4c4ace81ce60b347558f9419fe3c33d8bf7)
its wrapper around OTP's gen_fsm from the standard library because it is difficult to understand and suggested that
developers seek other finite state machine implementations.
This is understandable, but some of us still need/prefer to use the OTP gen_fsm.
I took the basis of Elixir's old
[GenFSM.Behaviour](https://github.com/elixir-lang/elixir/blob/a6f048b3de4a971c15fc8b66397cf2e4597793cb/lib/elixir/lib/gen_fsm/behaviour.ex)
and added some additional convenience methods. Currently missing are the `start_link`, `stop`, and `enter_loop` methods
