The default behavior of dbg/2 when running an application via IEx (e.g. iex -S mix phx.server) is to halt execution and request to pry into the executing context.
However, in most cases I just want dbg/2 to behave a like a fancier IO.inspect/2.
This can be accomplished by adding this configuration to ~/.iex.exs:
# Change behavior of dbg/2 to stop prying when in IEx
Application.put_env(:elixir, :dbg_callback, {Macro, :dbg, []})=> [1] dbg/2 | [2] pry/0 | [3] IO.inspect/2
