[Mono-devel-list] Extending mcs

[Rodrigo B. de Oliveira]

The boo compiler is based on a pipeline architecture in which parsing just 
happens to be the first step of most standard pipelines.

You can provide a different parser and still take advantage of all the 
extensibility goodies: syntactic attributes and macros. In other words, the 
source code would still be c# compatible. The generated code wouldn't even 
depend on Boo.dll in most cases.

For instance:

class Customer
{
     [getter(FirstName)] string _fname;

     public Customer([required] string fname)
     {
           _fname = fname;
     }
}

is valid c# but would be expanded by the boo compiler to:

class Customer
{
     string _fname;

     public Customer(string fname)
     {
           if (null == fname)
           {
                 throw new ArgumentNullException("fname");
           }
           _fname = fname;
      }

      public string FirstName
      {
            get
            {
                 return _fname;
            }
      }
}

I haven't checked XC# lately but last time I did I think they provided 
something like that, right?

cheers!
Rodrigo
