Overview

Class represents a config option that is possibly callable. Examples:

config.names.stack
config.names.task_definition

Abstraction is definitely obtuse. Using it to get rid of duplication.

#layer_levels(prefix = nil) ⇒ Object

Works similiar to Layering::Layer. Consider combining the logic and usin Layering::Layer

Examples:

prefix: .ufo/config/#{Ufo.app}/env

Returns

.ufo/config/#{Ufo.app}/env.rb
.ufo/config/#{Ufo.app}/env/base.rb
.ufo/config/#{Ufo.app}/env/#{Ufo.env}.rb

  end
  add_ext!(paths)
end

#load_project_config ⇒ Object

load_project_config gets called so early many things like logger is not available. Take care not to rely on things that rely on the the config or else will create and infinite loop.
