Hello, i wonder if it is possible to setup something on raspberry, so that the puredata-watchdog will restart pd-0.48.0 automatically? where could i look up the mechanics of this, unfortunatly i am not a unix crack…
Are you referring to the pd-watchdog binary, that comes with puredata- core? Is your Raspberry Pi running Raspbian?
From what I understand, the purpose of the pd-watchdog is to pause Pd in regular intervals when running in real-time mode. I think this is measure to prevent Pd from locking up the system. Assume you accidentally trigger an [until] without a stopping mechanism, thanks to pd-watchdog you're still able to move the mouse and quit Pd.
Is your goal to make sure that Pd is running at any time, so that it is started again as soon as it stops? Maybe you can achieve something like this wit a shell script. I haven't tested this, but it might give you an idea how to make it work:
#!/bin/sh
while true do # We start pd and send detach it from the terminal ('&') /usr/bin/pd -open yourpatch &
# we catch pd's process id pdpid=$!
# now let's wait for the process to terminate wait $pdpid
# once pd terminates, we start another iteration # of our while-loop done
I like until !!; do :; done which restarts the last command from bash_history in case it exits without a clean 0 exit status. Useful for all sorts of things. I guess it can also be written as until pd myCrashingPatch.pd; do; :; done
