Configatron is a new Ruby library that makes it easy to have persistently accessible configuration data available through your Ruby application. It bears some similarities to the Rails pluginSimpleConfig, but being distributed as a gem, is suitable for non-Rails applications. To install: gem install configatron

Once configatron is installed, the following code will get things going:

configatron do |config|
config.app_name = “My Awesomely Jazzy App”
config.database_url = “postgres://localhost/somedb”
# etc…
end

And then you can access these configuration variables throughout your application, like so:

configatron.app_name # =”My Awesomely Jazzy App”
configatron.database_url # =”postgres://localhost/somedb”

Note that this only gives a very cursory look at what Configatron offers, however, as it has many other features – including namespacing and nested configurations. Read More
