th31nitiate / redfour-elixir

A test repository for RedFour: elixir course. This has been used like some type of note taking system via commits. It is mainly for my own use but thought I would make it public so peeps that are working through have something to reference when stuck. I also use this for training by performing updates/experiments on a codebase that I am familiar with.

Installation

run "iex .S mix"

This will give you a shell, then you can play with the modules.

The correct escape value is alway 11.2 for the earth. You can use this to generate a a struct in to the module.

defmodule Physics.Planet do
  defstruct [
    name: "Earth",
    radius: 6.371e6,
    mass: 5.97e24
  ]
end

Physics.Rocketry.escape_velocity(Physics.Planet.struct)

We have created the Converter module, this allows us to seprate funcation logic to diffirent modules.

I have added tests for, we can use the following url to verify unknown values. mass/kg radius/meters
