I’ve been following along with the book and have noticed there’s some code missing.

Page 49: We create the inital Acceptor module, the paragraph mentions that it is a GenServer but in the code block we are not invoking the GenServer or adding the start_link function.

Page 55: We register to the BroadcastRegistry and BroadcastRegistry registries, but do not alias them into the module.

Page 67: We reference the Chat.AcceptorPool.Acceptor in the code and the paragraph mentions that we should be able to pass the tests after changing our supervisor tree. We are not given the code for the Chat.AcceptorPool.Acceptor.

I understand that these are minor issues that an experienced Elixir developer will have no issue with. I am a less experienced Elixir dev and these issues left me with non-functional code and caused me to debug, looking at the included code repo for what I was missing. It would be nice if the book contained all necessary code.
