Kernel Component Registration Strategies

[Craig Neuwirt]

The recent changes to the kernel registration interface allows for custom registration strategies.   I just added an AllTypesOf strategy to allow for the most common scenarios. 

Here are some examples

• registering all controllers in the current assembly 
  
• kernel.Register( AllTypesOf<IController>
       .FromAssembly( Assembly.GetExecutingAssembly() )
        );

• selecting the first interface as the service
  
• kernel.Register( AllTypesOf<ICommon>
        .FromAssembly(Assembly.GetExecutingAssembly() )
        .WithService.FirstInterface()
         );

• Using custom configuration
• kernel.Register( AllTypesOf<ICommon>
        .FromAssembly( Assembly.GetExecutingAssembly() )
        .Configure( component => component.LifeStyle.Transient
                              .Named( component.Implementation.FullName + "XYZ" )
                              )
         );
• Choosing types if they have a specific attribute (courtesy of LINQ)
• kernel.Register( AllTypesOf<CustomerChain1>
          .Pick( from type in Assembly.GetExecutingAssembly().GetExportedTypes()
                   where type.IsDefined(typeof(SerializableAttribute), true)
                   select type
                   ));

Thanks to Ayende for inspiration from some of his Binsor work!!!

You are taking all the fun out of Binsor :-)

[Craig Neuwirt]

Oh no,

  It would take a lot more magic and probably c# 6.0 to be able to do that!!!  In fact, the registration updates had Binsor in mind.  I am going to replace all the custom extension stuff in Binsor with a single ComponentRegistration.  This will eliminate most of Binsor code and finally have a single unified registration approach so other tools besides boo and have some fun.  Gotta get my RhinoTools Nant building happily from trunk first :-)

How's Seattle treating you?

This is really cool. Awesome work.

Hi , first of all it is nice work. !! Thank you.

I have a question about binsor to optimize register components text format in boo files.

I want to use this code block in my boo files : 

"var kernel = new DefaultKernel();

using (kernel.OptimizeDependencyResolution())
{
    for (int i = 0; i < 500; i++)
    {
        kernel.AddComponent("key" + i, typeof(string), typeof(string));
    }
}

"

below you can see my boo code.

"private def RegisterRepositories():

   for type in AllTypes("<myAssebmly>"):

       continue unless typeof(cr.IRepositoryBase).IsAssignableFrom(type)

       keyType = TypeHelper.GetTopLevelRepositoryInterface(type)

       if not Kernel.HasComponent(keyType):

           Component type.Namespace + "." + type.Name.ToLowerInvariant() + ".repository", keyType, type

"

how can i you "using" c# keyword in my case. 

i'll be happy with your helps.

Thanx...

Ümit
