Java guys aren't the only IoC geeks.
In the Ruby world you have Copland which borrows ideas from HiveMind, while putting a Ruby twist on things.
Rather than XML, or SDL, they use good ole YAML which ends up like:
id: quickstart
service-points:
SimpleService:
create-instance:
class: simple-service/ASimpleService
The manual is nicely written, and it is fun to see that the introduction has two answers to "What is Copland?".
Copland sans Buzzwords
Copland avec Buzzwords
Features
Currently, Copland features the following buzzwords:
Type 2 IoC (setter injection)
Type 3 IoC (constructor injection)
YAML-based descriptor configuration
Object-, Class-, and Singleton-backed services
Service factories, with extendable rule-processing engine for defining new factories.
Interceptors (for adding basic AOP-like “pre” and “post” hooks to every method of a service)
Multicast services, which do nothing themselves except delegate recieved messages to a set of other interested services.
Event/Listener infrastructure, for notifying services at various points during another service’s lifecycle.
dRuby and SOAP support, in the form of two core services that applications may use to export their services to remote clients.
