      mix new orval

    You will see in your terminal

    * creating README.md
    * creating .formatter.exs
    * creating .gitignore
    * creating mix.exs
    * creating config
    * creating config/config.exs
    * creating lib
    * creating lib/orval.ex
    * creating test
    * creating test/test_helper.exs
    * creating test/orval_test.exs
    
    Your Mix project was created successfully.
    You can use "mix" to compile it, test it, and more:
    
        cd orval
        mix test
    
    Run "mix help" for more commands.
    

    Intersting note: we decide to use Orval as a project name in honor to Anne-Françoise Pypaert, the first female Trappist brewmaster. You can know more abot her story in this link:

  • Running our code

    Starts iex in the context of your project—it uses mix to build the application environment and then enters iex

    iex -S mix 

    If your terminal is showing like below you are in the rigth way 👍

    Erlang/OTP 21 [erts-10.3.1] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [hipe] [dtrace]
    
    Compiling 1 file (.ex)
    Generated orval app
    Interactive Elixir (1.8.1) - press Ctrl+C to exit (type h() ENTER for help)
    iex(1)>
    
    

  • Write a FindWord Module Open Orval project in your favorite editor You should have some tree folder like this

    |_____build
    |____config
    | |____config.exs
    |____lib
    | |____orval.ex
    |____test
    | |____orval_test.exs
    | |____test_helper.exs
    |____.formatter.exs
    |____.gitignore
    |____mix.exs
    |____README.md
    

    Create a new file find_word.ex under lib folder. We suggest you install a plugin like: ElixirLS Open your new file let's start define the name for our module, Every Module in elixir is defined like below

    defmodule FindWord do
    
    end

    Inside FindWord write a function say_helow

    defmodule FindWord do
    
      def say_hellow do
        IO.puts "Hellow Elixir Girls"
      end
    
    end

    Now go to your terminal and run recompile just to compile our new changes

      iex(2)> recompile
      :ok
    

    Type FindWord.say_hellow
