Probe

Tired of the output from 10,000 IO.inspect statements cluttering your terminal?

Power you debugging with Probe!

defmodule BugFest do
  require Probe#, as: P

  def do_something_badly(with_args) do
    case with_args |> munge() |> Probe.i do
      :one -> true
      :two -> false
    end |> Probe.green(:do_something_badly)
  end

  def munge(args) when is_list(args) do
    :one
  end
  def munge(args) do
    :two
  end
end

BugFest.do_something_badly([:right, :then, :now])
 munge(with_args)  :one
 :do_something_bady  true
:one

All of the convenience of IO.inspect with none of the confusion.

Plus, colours.

Disabling in Production

If you carry the shame of your debugging into production then you can at least reduce the impact of your incompetence by disabling Probe completely.

Just add

config :probe, disabled: true

into config/prod.exs to not only disable the logging output but also (since Probe uses macros) completely remove the debugging code from your apps. (You may need to provoke a re-compilation of your app to see the change appear.)

Installation

If available in Hex, the package can be installed by adding probe to your list of dependencies in mix.exs:

def deps do
  [{:probe, "~> 1.0.0"}]
end

Documentation can be generated with ExDoc and published on HexDocs. Once published, the docs can be found at https://hexdocs.pm/probe.
