ApplicationConfig
=================

Basically there are 2 levels of configuration:

1) application wide which is configured in config/application.yml
2) environment specific which is configured in config/environments/application-#{RAILS_ENV}.yml

The environment specific configs override the applicaiton wide config


Example
=======

script/install plugin git://github.com/asynchrony/application_config.git

Then if for example in your config/application.yml you had:

mail_host: example.com

And in your config/environments/application-production.yml you had:

mail_host: production.server.com

you could in your code do:

ApplicationConfig::Base['mail_host'].to_s or
ApplicationConfig::Base.mail_host.to_s

At the moment you really need the to_s on the end.

Also, if you want to do a nil check you need to put the applicaiton config on the LHS:

if ApplicationConfig::Base.mail_host == nil

Because of the way it's working.

For testing, first:

require 'application_config_test_ext'

in your test_helper

And then before any test you want to alter the config for:

ApplicationConfig::Base.add(
<<EOF
mail_host: test_mail_host
EOF
)

Which will change the config for that test and then rollback to what it was before the test. 
This allows you to test behavior off of the singleton config object.
