Debugging

New features:

• debugging Drab functions directly from IEx console:

When starting Phoenix+Drab from iex -S mix phoenix.server the following debug instructions appear:

[debug] 
    Started Drab for /drab, handling events in DrabPoc.PageCommander
    You may debug Drab functions in IEx by copy/paste the following:
import Drab.Core; import Drab.Query; import Drab.Modal; import Drab.Waiter
socket = GenServer.call(pid("0.666.0"), :get_socket)

    Examples:
socket |> select(:htmls, from: "h4")
socket |> execjs("alert('hello from IEx!')")
socket |> alert("Title", "Sure?", buttons: [ok: "Azaliż", cancel: "Poniechaj"])

You may use it to debug. Just copy/paste this lines and you may remote control your browser from IEx REPL:

iex(1)> import Drab.Core; import Drab.Query; import Drab.Modal; import Drab.Waiter
Drab.Waiter
iex(2)> socket = GenServer.call(pid("0.666.0"), :get_socket)
%Phoenix.Socket{assigns: %{__action: :index,
   __controller: DrabPoc.PageController, __drab_pid: #PID<0.666.0>,
   ... 
   transport_pid: #PID<0.1548.0>}

iex(3)> socket |> select(:htmls, from: "h4")
