DecorateWith Syntax

[StarTrekRedneck]

I find myself wanting a decorator pattern syntax similar to...

x.For<IInterface>().Use<Implementation>()
                   .DecorateWith<Decorator1>()
                   .DecorateWith<Decorator2>();

In the past (v2.6) I used an extension method by Matt Honeycutt that gave me this (from his blog)...

cfg.For<IProductRepository>().Use<InMemoryProductRepository>()
                             .Decorate().With<ProductSecurityDecorator>()
                             .AndThen<ProductRepoLogger>()
                             .AndThen<RudeProductRepoLogger>();

Am I missing something in StructureMap v3, or can we add this kind of decorator syntax?

Looking at the acceptance tests on github shows the syntax I think you're looking for:

https://github.com/structuremap/structuremap/blob/a5badbc2fff19f8394991ac94c9495a0c28496c0/src/StructureMap.Testing/Acceptance/interception_acceptance_tests.cs

Does that point you in the right direction?

Yes, thanks Jeff!

x.For<IInterface>().Use<Implementation>();
x.For<IInterface>().DecorateAllWith<Decorator1>();
x.For<IInterface>().DecorateAllWith<Decorator2>();

The last decorator will be the outermost wrapper (as one would expect), and the .Use<Implementation> does not have to be declared first-- it can go anywhere (it's last in the acceptance tests).

Additionally, the Scan() feature can still register the default implementation. So, without establishing custom conventions, I wouldn't have to register an implementation for IWidget if the implementation was named Widget, and decorators would still be appropriately applied.

Awesome, glad that helped.
