Hi Spencer, Very useful info. I'll snip a lot and only comment the stuff I have more questions or additions for.
Additionally, you can save a little time/memory by using arrays of null UGen references, rather than arrays of UGens. Hmm isn't this a bit suspicious, in terms of semantics. I mean the default of instanciating arrays as though objects where already constructed. If they are added, that design cannot support classes that lack a parameterless constructor, singleton classes in which it is private, and abstract classes or interfaces which cannot b instanciated in the first place.
That should be okay--when constructors and abstract classes are finally implemented in ChucK, the gotchas you mentioned can and should be caught by the compiler.
IS string also a class? I read something to that effect but cannot find its methods anywhere. I don't seem to be able to do much apart from concatenating them.
It is a class, but it doesn't have any documented methods (yet).
will there be a template mechanism or the ability to downcast arguments? You can always cast them to back to what they were initially, using the $ operator. You just have to actually know what they are. Ah that's the question. Quite OK for homogenous stuff but I can already imagine a design in which this is not known. IN which I have to branch on a type name. That's a bad smell in OOPy circles often but not always. Many recursive data structure dumpers require, for example, that you know whether an element is a single item, some reference to an array or object or something else. Not very relevant to chucK right now, though, as there's no serialization support.
Yes, ChucK is definitely not the language for OO purists...
don't know yacc either, but in my experience its pretty easy to pick up the basics by just reading a .y file. Ah I'll take a look. I'll be lazy and ask if there's a direct URL to the current CHucK yacc grammar. I usually don't get the source, though in this case it might be beneficial.
You'll probably have to take a look at the source, as the repository is not online. If you have a cvs client on your machine, then something like cvs -d :ext:anon-chuck@cvs.cs.princeton.edu:/cvs checkout chuck_dev/ v2/chuck.y should also do the trick. Just be sure to replace the ' at ' with an actually 'at' sign, as I believe the list server automatically replaces at signs with ' at ' to foil the spam bots. spencer
