Hi! I want to replace “default definee” when I require ruby file.

A short example: [config1.rb · GitHub](http://gist.github.com/461094)

Of course, it says that One::Configuration is an uninitialized constant.

So, here is my question: how to require configN.rb so that all  
definitions are done inside the module?

Thanks in advance,  
Daniel.

You can’t do this with require. You probably want module\_eval

module One  
module\_eval File.read(“config1.rb”)  
end

module Two  
module\_eval File.read(“config2.rb”)  
end

def process(config)  
puts config.value  
end

process One::Configuration  
process Two::Configuration
