# Snooper

Easily debug, inspect, and log a function's behavior on a line-by-line basis.

Use like so:

    defmodule SnooperReadme do
      import Snooper

      snoop def my_function(a, b) do
        c = a + b * a + b
        d = c * c
        {alpha, beta} = {c * d, c + d}
      end
    end

Gives colorized output like:
