How to store Configatron persistently, after Ruby app has run

Question

I'm pretty new to Ruby (though not to programming) and am trying to create a persistent config. Though I thought using Configatron would automatically make my config persistent, it does not seem to be the case. How would I make this persistent throughout multiple runs? Should I store this to a file? If so, how? I would think a ~/.myapp file might be good?

Persistence in Rails

If you're using Ruby on Rails, you need to modify your initializers for this gem:

• app/config/configatron/defaults.rb
• app/config/configatron/{development,test,production}.rb

Persistence Without Rails

Ruby Modules

If you're using Ruby itself, rather than the Rails framework, then you need to persist your configuration as a Ruby module (e.g. require "my_configuration") or serialize the Configatron class if it can serialized. It looks like the goal of the gem is to avoid serialization, so requiring a module that contains your configuration as executable code seems to be the canonical approach for this gem.

Serialization

I don't use this gem myself, so you'll have to experiment with serializers to see if they work for your use case. For serialization, I'd recommend using one of:

• YAML::Store
• PStore
• Marshal

However, if you're using serialization to save and load your configuration, I'm not entirely sure why you'd need this gem in the first place. Your mileage may certainly vary.
