Hi list,
I am a happy user of Chris McCormick's recent suggestion for Pd/shell communication using [netsend], [netreceive] and a shell script piping commands from/to pdreceive/pdsend in a while loop (based on a solution by Claude):
http://lists.puredata.info/pipermail/pd-list/2009-02/067864.html
However, this ceases to work when the Pd patch is restarted, since the ports remain occupied. While one can close the link from Pd to the script before restarting the patch using the [disconnect< message to [netsend], there seems to be no clean way of closing the connection from the script to Pd.
I am guessing that one would need to modify Chris' script in a way that it is possible to send a 'disconnect' event from Pd to the script, which causes it to close the pipe to Pd, right?
Not being the world's greatest shell scripter, I would appreciate any hints on how this could be accomplished.
best, flo.H
Flo,
i am sure you have tried this, and others have suggested it too, but there is always the [shell] external in externals/ggee i think.

I am limiting myself to vanilla Pd for this particular application. This is a project eventually aiming at PD anywhere running on an ARM processor, and I would like to avoid any cross-compilation I don't strictly need to do.
Also, to speak with Chris, I am a fan of vanilla Pd, and there is of course also the good old urge to learn ;-)
Thanks for the hint, though.
best, flo.H
