Created December 18, 2017 04:49 — forked from christhekeele/1-uses_tracker.ex

A way to know what modules a module has used in Elixir.

	# A way to know, at runtime, what modules a module has used at compile time.
	# In this case, you include `UsesTracker` into a module. When that module gets
	# used in some other module, it registers itself with the other module.

retgoat / 1-indirect_uses_tracker.ex

Created December 18, 2017 04:49 — forked from christhekeele/1-indirect_uses_tracker.ex

A way to track when modules are used in Elixir, and an example adapter/plugin architecture built on top.

	# For simpler use cases, see the UsesTracker instead:
	# https://gist.github.com/christhekeele/e858881d0ca2053295c6e10d8692e6ea


	###
	# 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.
