Hi
Assuming a process is running in OSX, and it is printing to stdout. I want to create a GUI to display the data. How do I get that data?
I have seen some mention that IPCsocket will do it. Also I wonder if a TextInputStream would work.
I’ve used IPCsocket, which uses a file. Could the answer be to redirect stdout of the process to that file, then read same with IPCsocket?
Thanks Christian.
So using Shell, I assume I need to launch the process from the Xojo desktop app…correct?
I think that should work for what I want to do. But to be thorough…what if the process is already running? One could use Shell to run ps, parse the result, and get a process ID. But from there…?
That sounds interesting. I use ‘screen’ all the time for serial I/O. Can you give me an idea how one would launch using screen? That is a big man page. I don’t like reading that much
I have been trying to run some embedded MCU C code on my Mac, as a process. I rewrote the hardware abstraction layer to do the I/O using stdin and stdout. The I/O has been encoded to indicate whether the text represent I/O bit state, analog voltage, user serial communication or whatever. That project stalled when I couldn’t figure out how to get a single character typed from the console (it is easy on Linux but not Mac). Which brings me back to ‘screen’. I presume it would be possible to create a virtual comm port that would show up in /dev. I don’t know how to do this in C, and that is off-topic anyway. But I wonder if that is possible in a Xojo console app? Is there a way that a Xojo console app can create a virtual serial port in /dev?
