Real-World Event Sourcing: Missing setup instructions (page 3)

@autodidaddict,

On the website it states: “What You Need: You’ll need a computer preferably running MacOS, Linux, or WSL/Ubuntu on Windows. You’ll install everything else you need (such as Elixir and an event store) as you progress through the book.”

So, I expect some sort of aside or maybe a section in the introduction about what tools to install for those of us that don’t already have the necessary tools. However, on page three it says “go ahead and create this module as calculator .exs. Start up iex and enter c(“calculator .exs”) to load and compile the module.”. I would therefore expect by this point to have been given some guidance as to what tools to install, as this is the first point in the book that I need it.

As someone who does not use Elixir, I don’t know the toolset, so the text needs to be explicit about what tooling I need to get going with the examples. It doesn’t have to be comprehensive, it just needs the basics to point me to the relevant websites and tell me what I need in order to get started. I’m sure from that point I can Google the rest if I need it.

First Post!

I’m also at the beginning of reading the book. I’d assume the author meant installing the language.

go ahead and create this module as calculator .exs. Start up iex and enter c(“calculator .exs”) to load and compile the module

You can access iex shell after installing Elixir successfully. The c("calculator.exs") is typed once you’re inside iex shell.

On the website it states: “What You Need: You’ll need a computer preferably running MacOS, Linux, or WSL/Ubuntu on Windows. You’ll install everything else you need (such as Elixir and an event store) as you progress through the book.”

Not sure if they’ll update this to be less ambiguous
