Overview

A class used for storing “leveled” configuration options.

In this class any “user” specified options take precedence over any “file” specified options, take precedence over any “default” options.

User input is preferred over “defaults”:

user_options    = { foo: "bar" }
default_options = { foo: "zoo" }
options = UserFileDefaultOptions.new(user_options, default_options)
puts options[:foo]
# => "bar"

All values can be accessed via #all_of

puts options.all_of(:foo)
# => ["bar", "zoo"]

A “file” option can be set. This config will be preferred over “default” options but will defer to any available “user” specified options.

user_options    = { foo: "bar" }
default_options = { rackup: "zoo.rb" }
options = UserFileDefaultOptions.new(user_options, default_options)
options.file_options[:rackup] = "sup.rb"
puts options[:rackup]
# => "sup.rb"

The “default” options can be set via procs. These are resolved during runtime via calls to #finalize_values
