Setup Elixir History:

1. touch ~/.iex_history
2. Set the ERL_AFLAGS env var: bash: echo "export ERL_AFLAGS='-kernel shell_history enabled'" >> ~/.bashrc zsh: echo "export ERL_AFLAGS='-kernel shell_history enabled'" >> ~/.zshrc fish: set -Ux ERL_AFLAGS '-kernel shell_history enabled'
3. Add some history:

   $  iex                                                                                                                                                                 (/f/s/2/s/script_drop) 12:09:25
   Erlang/OTP 22 [erts-10.4.3] [source] [64-bit] [smp:12:12] [ds:12:12:10] [async-threads:1] [hipe]
   
   Interactive Elixir (1.9.0) - press Ctrl+C to exit (type h() ENTER for help)
   iex(1)> :hi
   :hi
   iex(2)>
   BREAK: (a)bort (c)ontinue (p)roc info (i)nfo (l)oaded
          (v)ersion (k)ill (D)b-tables (d)istribution
   ^C
   

4. Load the history:

   $  iex                                                                                                                                                                 (/f/s/2/s/script_drop) 12:09:25
