Am I missing some kind of readline facility in my setup?
I am trying out a small app using Plug, using the code from this question - Simple Elixir web page - use Phoenix or not?, which is based on the Plug docs - Plug — Plug v1.20.2.
After I use Ctrl-C to stop the server, recompile and restart I realize that I can’t use the cursor key to recollect the commands from the previous session.
The cursor keys give only the commands I have entered in the new iex -S mix session.
Is that the normal behaviour? Command line tools mysql and psql have a history going back to previous sessions and I wonder if iex has the samel

I guess this is one question I can answer myself. I came across it when trying out erlang but couldn’t remember the debian package name, rlwrap
There is another option using a Erlang History
More about both here - http://stackoverflow.com/questions/22426716/how-to-save-log-the-output-of-the-iex-shell-to-get-persistent-command-history/28514369#28514369

I use this in my dev env
I would not use this in production (due to production paranoia 
).

Unfortunately, there is no such feature because it’s not supported by the underlying Erlang shell. There is a closed issue on Github which documents this: Saving iex history to a file between runs · Issue #2945 · elixir-lang/elixir · GitHub
The erlang-history module mentioned by @outlog and also referenced in the Gihub issue seems to be a little bit hacky and its author stated that the history might get corrupted from time to time. But still, better than no history at all, I suppose
