YAML based DRY settings manager.

The YAML expansion functionality came about by our getting tired of having to create a YAML file and then create an initializer that would expand such file and include in our applications.

Figleaf::Settings can be used to override settings depending on what environment your application is running. If it's a Rails app, it will know it from Rails.env, otherwise it will check for ENV['ENVIRONMENT'].

Add this line to your application's Gemfile:

gem 'figleaf'

And then execute:

$ bundle

Or install it yourself as:

$ gem install figleaf

In application.rb:

Figleaf::Settings.configure_with_auto_define do |s|
  s.env = Rails.env
  s.some_awesome_flag = true
  s.load_settings
end

Then, you can override any particular setting inside your environments/*.rb files.

eg: In production.rb

Figleaf::Settings.configure do |s|
  s.some_awesome_flag = false
end

etc...

Then, in your app, you can reference Figleaf::Setting.some_awesome_flag?.

Also, it provides the ability for you to define all your environment dependent settings in just one YAML file inside config/settings/. The anatomy of these files should be:

development:
  foo: bar
  some_bool_property: true

test:
  foo: flob
  some_bool_property: false

production:
  foo: foo
  some_bool_property: false

The Figleaf::Settings parser will create a namespace for your YAML file after the file name.

Then, assuming that you named your YAML file mysetting.yml. you can just access foo as Figleaf::Settings.mysetting["foo"], Figleaf::Settings.mysetting[:foo] or even Figleaf::Settings.mysetting.foo (the one caveat of the method expansion is that you can't access attributes that collide with Hash methods that way, like key). (Inspired by Rails' database.yml, of course.) In the case of boolean values, the property is available as a predicate (eg: Figleaf::Settings.mysetting.some_bool_property?)

You can also use Figleaf::Settings.override_with_local! to load particular file settings in runtime.

Properties can also be lambdas.
