[Ironruby-core] Handling C# lower case namespaces

[Tomas Matousek]

Thumbs up :)

You might however expect this to work for all CLR types. In which case you can indeed monkey patch it as well (kind of):

>>> class Object
...   def to_s
...     self.class.name[0,8] == "System::" ? to_string.to_s : super
...   end
... end
=> nil
>>>
=> nil
>>> require 'mscorlib'
=> true
>>>
=> nil
>>> System::Convert.to_int64(1234)
=> 1234

Just monkey-patch it:

class System::Int64

     def inspect
          self.to_string.to_s
     end
end

;)

Well, that's very unfortunate. They seems to break .NET guidelines for namespace naming. It's not compatible with Ruby language to have lowercased namespaces since they behave like modules. Module names must start with an upper case. We can add some API to overcome this, but it won't be pretty. Something like



clr.class_get :foo, :bar, :baz would return class for type foo.bar.baz.



For now you can use reflection API to get the type (and Ruby class for that type):

System::Type.get_type("foo.bar.baz").to_class



As for Int64... it prints #<System::Int64:0x000005e>, which is not particularly useful. It should probably call ToString. I'll file a bug.

It seems like the current version does not handle lower case namespaces when referencing a .NET DLL.  It thinks it is a method call whenever a constant starts with lower case.  It also doesn't handle non-alphabet characters such as _ (underscore).

I'm trying to call WCF service from IronRuby via the proxies file.  svcutil converts all namespaces in the proxies file to lower case.  Here's some info on it:

I also noticed that "puts" does not output the value of Int64.  However, it does if I use Console.WriteLine in my ruby program.
