Windows CRLF in config files causes errors in mix task lvn.setup.config

[bowyern]

When running mix lvn.setup.config I have this syntax error on import:

$ mix lvn.setup.config
Write to config/config.exs
(Y)es (n)o (d)iff
> y
Write to config/dev.exs

I'm adding lvn to an existing phoenix application (1.7.18, originally 1.7.2).

I added the 0.3.0 dependencies from the getting started readme, then ran mix lvn.setup and mix lvn.setup.config.

That import only shows up in our router.ex. Brian asked for the first 10 LOC from that file:

defmodule PortalWeb.Router do
  #alias PortalWeb.PageController
  use PortalWeb, :router

  import PortalWeb.UserAuth

  pipeline :browser do
    plug :accepts, ["html"]
    plug :fetch_session
    plug :fetch_live_flash
    plug :put_root_layout, {PortalWeb.Layouts, :root}
    plug :protect_from_forgery
    plug :put_secure_browser_headers
    plug :fetch_current_user
  end

@bowyern could you try 0.4.0-rc.0 for all of the libs except stylesheet? Have that be 0.3.2

I cannot reproduce this on main

This appears to be caused by CRLF line endings.

$ file config/config.exs
config/config.exs: ASCII text, with CRLF line terminators
$ file ../../lvntest/config/config.exs
../../lvntest/config/config.exs: ASCII text

Running dos2unix on each of config.exs, dev.exs, test.exs, endpoint.ex, and router.ex fixes it.

thank you, I'll try to tackle this for rc.1
