Re: [Grammatica-users] Grammar for "Nesting"

[Patrick M Gremo]

This is close.



But I think what I need is something like:

Message = [Object | Message] MethodCall

But this gives me an infinite loop.

I think I can describe it as:

A Message can have an Object OR another Message coupled with a MethodCall.










I think a production for Message could look like this:

  Message = MethodCall Message?
          | Object Message? ;

This will allow an infinite list of method calls and
objects mixed together. If the Object production can
only be placed at the end, you'd write the production
like this:

  Message = MessageCall Message?
          | Object ;

Cheers,
