###
# A way to know, at runtime, what modules a module has used at compile time.
# In this case, you include `IndirectUsesTracker` into a module. When that module gets
# used in some other module, it makes that module registerable under a namespace of your choosing.
# When the registerable module is used into a third module, that third module will know at runtime which
# registerables were `use`d in it at compile time, via a function titled after the namespace.

# You will need fswatch installed (available in homebrew and friends)
# The command below will run tests and wait until fswatch writes something.
# The --stale flag will only run stale entries, it requires Elixir v1.3.

defmodule HendricksFormatter do
	@moduledoc """
	This module is a formatter plugin for Elixir's `mix format` task
	that converts leading whitespace to tabs.
	It tries to intelligently determine the tab width based on the most common
	counts of leading space runs in the file.
	It allows additional space characters for minor adjustments that are below the tab width.
	OK, why tabs? Why resurrect this age-old nerd debate again?
	Very simple: It's an accessibility issue:
