abstractions and objects WAS: Re: [PD-dev] [Fwd: PD-cvs Digest, Vol 2, Issue 5]

26 Apr 2005


      The more code in CVS, the better as far as I am concerned.  We can  
figure out how to distribute and organize it separately.
But that reminds me of another, related idea.  I think we should be  
trying to implement Pd objects in Pd as much as possible, and therefore  
making a distinction between objects written in Pd, which are basically  
"externals", and patches that are more like a finished application  
(performance patches, examples, etc.).
Though I know that "abstractions" is an old, established term in  
regards to the Max family of languages, I think that with Pd it is  
somewhat misleading.  Ideally there should be no distinction between Pd  
objects written in C, C++, python, Tcl, TK, and even Pd itself.
That leads me to: is having a separate area for "abstractions" useful?   
Personally, I have been putting the objects written in Pd into my  
directory in "externals", but maybe it makes sense to have the objects  
written in Pd all in the "abstractions" section.  But I think there  
should be a separate section for applications, performance patches,  
examples, etc.  So objects would go into "extra" and apps, examples,  
etc. would go somewhere else, perhaps an entirely separate distro, or  
even a separate CVS repository so that we can freely grant CVS access  
to that distro without having to grant access to the core pure-data  
CVS.  We could also just use ACLs is that's a problem too...	
Thinking out loud...

hello,
i'm tring to clean my pd directory, in order to share all abstraction  
i made that can be usefull for others.
i don't have lot's of time now, so it's quite slow, but in the future  
you'll find in the abstraction/nusmuk folder a set of simple but  
usefull abstractions.
the first one is another granular synthesys exemple.
i hope it's ok for everybody.
