[PD] netsend / netreceive for Max <-> Pd communication

[d.lj]

that help text in

pd/doc/5.reference/netsend.pd

should be updated to point to http://www.akustische-kunst.org/maxmsp/


[Olaf Matthes]->[Re: [PD] [announce] netsend / netreceive for Max <-> Pd...

 |okay, to avoid any confusion: in Pd's help patch for netsend some Max
 |objects called 'netsend' and 'netreceive' are mentioned (the link given
 |there does not work any longer...). These objects are different from the
 |ones I made and here is what's actually different:
 |- they only support UDP
 |- they only send messages consisting of <symbol> <float>
 |- the 'syntax' (i.e. how the patch has to look like) is different from
 |how it is done in Pd
 |
 |With my objects I've tried to stick as close as possible to the Pd
 |objects (but I don't support the 'old' flag....). So everything you see
 |in the help patches for Pd can be done exactly the same way in Max.
 |But the text in the netreceive help patch from Pd 0.36 still states
 |"Incoming network messages appear in 'receive' objects;" This is no
 |longer true (unless the 'old' flag is set to explicitly switch back to
 |this old mode).
 |
 |To send messages of arbitrary length, the following (using 'l2s' from
 |zexy) should work:
 |
 |[your list of arbitrary length with 23 floats and probably symbols]
 | |
 |[l2s]
 | |
 |[send $1]
 | |
 |[netsend]
 |
 |By converting a list to a symbol it shrinks down to a constant length of
 |always one symbol, regardless the original list length. netreceive will
 |unpack it into a list again before sending it through it's outlet.
