Emacs like editor in Elixir

[Boris Kuznetsov]

Hi,

I'm exploring the idea of writing Emacs-like terminal editor in Elixir.

The base idea is to run `mix run --no-halt` and then use libraries like
https://github.com/ndreynolds/ratatouille to manage termonal window.

You could recompile/extend your editor on the fly be running `r(Module)`
or use the helper `IEx.Helpers.recompile()`.

The issue I have is I'm getting compilation messages to the editor
window when I run recompillation. I think the source is from
`Mix.Utils.compiling_n/2`. Also, things like `IO.inspect/1` will write
directly to STDOUT.

I would like to redefine that to make it write to a different place,
basically to some variable/gen server when I can view it later by
issuing a command from editor.

So, my questions is basically this:

- is it possible to write Emacs in Elixir (in terms of live programming
environment)

- do I need to compile to a final app or it's possible only when running in
development mode, i.e. having tools lile mix/iex/recompilation

- should I write custom logging backend for `Mix.shell().info/1`, I
don't want to silence it with `MIX_QUIET` (but it looks like I'm still
can't silence compiling messages with this ENV variable)

Thank you
