Hi,
I am trying to make Pd connect to certain jack ports after startup. While on Linux I could use the jack_connect command line program to do so I am trying to make do from a bash script after having started Pd. Stupid me I am thinking of starting and detaching pd with -nogui in the script and, upon successful startup, call jack_connect. So far I have
pd -nogui -rt -jack -jackname blah -nojackconnect -open superpatch.pd -send "goto 10" & pidpd=$!
if [ $pidpd -eq 0 ]; then echo "Pd did not start successfully. Exiting script."; exit 1; else jack_connect pddel:output0 system:playback_1 jack_connect pddel:output1 system:playback_2 fi
But I would like to not detach Pd so that I can kill it and its script conveniently with command-c. Apart from writing a better shell script that eventually listens to the keyboard and then kills $pidpd, I wonder if there is a vanilla way™ to connect to jack ports from within pd after startup. I have not found something in the list archives so far.
Thanks for all hints! Peter
well, you could just foreground ("fg") the Pd-process after jack_connect did its job.
however, i think the proper way is to have a separate process running that auto-connects Pd, e.g. qjackctl with it's patchbay feature. there are others around as well (google for jack session management).
i'm *firmly* opposed to bloating the Pd core to add jack session management to "within Pd".
