There's this new thing also, called Purr Data, it has all the power of the
late extended, plus the power of the current vanilla

Re: [PD] maxlib/arraycopy & pd-essentials

[Fred Jan Kraan]

Hi Ed,

Did I understand correctly the object works in a predictable way in the 
end?


Sometimes I try to maintain a version of maxlib distributed with deken, 
and had the impression it worked as expected when I revisited the 
help-patch.


At the same time, I had the idea that this object, as there are a lot 
more in Max/MSP and pd-extended, are just convenience objects; could be 
as well a proper abstraction. Which would have much higher educational 
value IMHO.


It would be a nice project for the Pd-community as a whole to find the 
(few) essential objects missing from pd-vanilla and leave the rest of 
pd-extended as proper legacy; nice to have to get that old patch 
working, not otherwise not really useful.


Greetings,

Fred Jan

Re: [PD] maxlib/arraycopy

[Ed Kelly via Pd-list]

At the back of my mind, a thought that there must be a vanilla way of doing 
this. "I'm sure I saw it somewhere..." etc
Just as with the [text] objects, I'm gradually emerging from years of using 
Pd-extended 0.42/43 and realising the power of vanilla.Thanks Roman

Perfect. A way of doing it in Vanilla Pd. If I can gradually trim away the 
externals from my patches and vanillarize them I'll be a happy man.Thanks,Ed

Checkout help for new [array] class. There is [array get ] for
retrieving part of or whole array as a list. With [array set ]
you can update part of or whole array.

And there has always been:

[ (

[send ]

to update an array/table.

Re: [PD] maxlib arraycopy

[Matt Barber]

Fastest vanilla way now is to get the range from the source as a list with
[array get] and then write to the dest with [array set]. It's faster than
you'd think. You can do some minor bounds checking, but the way Pd ranges
work mostly takes care of that for you.

[PD] maxlib arraycopy

[Ed Kelly via Pd-list]

Hey list,
Recently my rechunk~ abstraction has ceased to work. I've recently re-installed 
and, it seems the maxlib/arraycopy object is not working the way it used to. I 
used to send it a list with[sourceArray start end destinationArray(values,but 
now, when the source array is longer than the destination array, I get error 
messages that:arraycopy: start point 1223199 out of range for destination 
chunk_2_13Where chunk_2_13 is an array created to be the same length as the 
chunk I wish to extract.
Does anyone have a better way of copying chunks from one array into another? Is 
there a vanilla way?
Questions, questions,Ed
