Hey all
I'm looking for the best available solution to execute commands from Pd. Ideally, the object would launch the process independently from Pd in order to avoid any lock-ups. Then, it'd be nice if there would be interfaces to access stdout, stderr and the exit code (probably an outlet for each). Third, it should allow to send signals to the running process. I found [moolib/popen], [motex/system] and [ggee/shell] and none of them fits for what I intend to do. [popen] and [system] don't give any feedback at all and probably are meant to run one-shot commands only. [shell] comes closest, it has an outlet for stdout and one for the exit code. However, on macOS only the the second outlet works (and gives correct exit codes) while the left outlet never outputs anything. On Linux, the left outlet outputs stdout, while the right outlet always gives 0 regardless of actual exit code. Ideally, I need something that works on macOS and Linux the same way.
I'd like to be able to control a handful of jacktrip[1] instances from Pd. I need to be able to evaluate their stdout to get feedback about their connection status. Also, I need to be able to kill them individually.
I'm also happy to explore ideas that think outside the box as long as the solution can be built into a Deken package.
Thanks, Roman
