A Better IO.inspect/2 for Debugging

I use IO.inspect/2 all the time when I'm debugging something, and I often run into a problem where I'm looking at a gigantic map with lots of fields that gets truncated. I usually want everything to be printed, and I have to remember the options to enable it. So for reference for my future self, here's a handy function that actually prints everything:

def io_inspect(item, opts \\ []) do
    opts =
      opts
      |> Keyword.put(:limit, :infinity)
      |> Keyword.put(:printable_limit, :infinity)
      |> Keyword.put(:width, 0)

    IO.inspect(item, opts)
  end

I kinda wish the default was to print everything, with options to truncate if desired. The power of defaults...

You can also customize the default behavior of IO.inspect/2 inside of IEx by putting the following in ~/.iex.exs:

IEx.configure(
  inspect: [limit: :infinity, printable_limit: :infinity, width: 0]
)
