class Puma::UserFileDefaultOptions

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 prefered 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 prefered 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`
