[Aspectsharp-users] Proposal

[hammett <ha...@uo...>]

Hiya!

So, here is my bunch of suggestion and the things I consider working on, at
least reserving some part of my spare time to focus on it:

---- Configuration language ----

Something better than xml to describe aspect configurations, with a
easy-to-grasp semantic and ressembling aspectj (although xml should still be
supported)

import MyAssembly
import OtherAssembly

// These declarations forms a global declaration that can be
// referenced by any aspect declaration
interceptors
{
  "shoot", MyInterceptorClass in AssemblyX;
  "logger", MyLoggerInterceptor
}

// Idem, ibidem
mixins
{
  "customer", CustomerClass in CustomerAssembly
}

// Aspect declaration
aspect JohnMcBrother for MyType
{
}

// or

aspect JohnMcBrother for (* in AspectSharp.Core)
{
}

// or (with some regular expressions)

aspect JohnMcBrother for (* in AspectSharp.Core !~ AspectEngine)
{
}
aspect JohnMcBrother for (=~ Customer*)
{
}

// Pointcuts

aspect JohnMcBrother for MyType
{
    pointcut execution(void DoSomething())
    {
       interceptor { "shoot" }
    }

    pointcut execution(*)
    {
       interceptor { "logger" }
    }

    pointcut execution(* get_*())
    {
       interceptor { MyStrangeInterceptor in MyStrangeAssembly }
    }
}

// Mixins

aspect JohnMcBrother for MyType
{
  // Mixins are now Ruby like :-)
  include "customer"
  include MyOtherMixin in MyOtherAssembly
}


This content will go through a lexer, parser and a semantic checking, and
meanwhline constructing a object model. This same object model can be used
in the xml configuration version.

---- Design changes ----

- AspectEngine be an instance class instead of a singletion/static
- Drop the IMixin, IProxyAware
- Drop the AopAlliance "support"

---- Refactoring ----

- The test cases are a bit confusing, I suggest start all this process by
creating brand new test cases, and only after that start to code this new
version.


What do you guys think?

Cheers,
