Hi there, I have a script named ListModules.exs that contains the below, defmodule ListModule do def sum([]), do: 0 def sum([head | tail]) do head + sum(tail) end end How can I run the above from a windows shell and call the function sum()? I tried to run elixir -r ListModule.exs -e …

Try outputting the result, otherwise it is just thrown away: ➜ ~ elixir -r ListModule.exs -e "ListModule.sum([])" ➜ ~ elixir -r ListModule.exs -e "IO.inspect(ListModule.sum([]))" 0 ➜ ~ elixir -r ListModule.exs -e "IO.inspect(ListModule.sum([1, 2, 3]))" 6
