How to stop input inside iex
How could I send an EOF/EOT inside an input in iex?
Say inside
iex> IO.read :all
Usually we do it by pressing ctrl+D on other shells, but that’s something else in Erlang.
If there isn’t a way, how could I stop the input in a way that I could access the data already entered?

It appears erl and iex both block the user from issuing the EOF signal, which can usually be done with Ctrl+d.
However, if you use elixir then it works!
$ elixir --eval 'IO.write("> "); l = IO.read(:stdio, :line); IO.inspect(l)'
> :eof
At the prompt above, I gave Ctrl+d and it got :eof like expected. However, this doesn’t work in iex; I assume this is on purpose to avoid accidentally terminating the shell input loop.
Hope this helps other future searchers
