Needle Dependency Injector for Ruby
http://rubyforge.org/projects/needle
[1.2] 18 Nov 2004:
* Parameterized services.
* Multiton services.
* Added Container#use, Container#use!, and Container#defaults for setting
default options for services.
* Added :log_for service, which is a parameterized version of the :logs
service.
* DefinitionContext now passes all unknown messages through to the
container.
* Updated manual and FAQ.
* Fixed bugs and documentation typos.
[1.1] 11 Nov 2004:
* Needle::Registry instances may be nested (i.e., given a parent).
* Needle::Registry instances may be given names
* The implementing classes of namespaces, interceptors, and definition
contexts are now services themselves, allowing clients to override them.
* Added a chapter to the manual describing how to override the namespace,
interceptor, and definition context implementations.
[1.0] 4 Nov 2004:
* Logging levels may be specified more flexibly and robustly.
* Added Container#require, to better support service libraries.
* Added DefinitionContext#namespace_define!. DefinitionContext#namespace! is
now an alias for that.
* FAQ and Users Manual are complete (first draft).
[0.9] 28 Oct 2004:
* Registry.new! is now Registry.define!
* Added Registry.define as a class method.
* Registry#fullname always returns nil. ServicePoint#fullname and
Container#fullname no longer include the registry itself in the
path.
[0.6] 21 Oct 2004:
* Added benchmarks.
* Removed Container#register!.
* Added Container#define and Container#define!, and changed semantics of
Registry#new!.
* Service constructor blocks may accept two parameters: the container, and
the service point itself.
* Container#namespace (and friends) no longer acts like "mkdir -p".
* Added QueryableMutex for detecting cycles in dependencies.
* Changed implementation of service models to use instantiation pipelines.
* Added many new service models (prototype_initialize, threaded,
singleton_deferred_initialize, etc.)
* Added Jim Weirich's "DI in Ruby" article to documentation.
[0.5] 14 Oct 2004:
* First public release.
