The way I understand your pipecom library (*please correct any error I may make here*) Is that it executes a shell command then stores either STDOUT or STDERR in string variables and Then returns after the command is finished !
A function I would like to see ? ? Is one that acts a bit more like _FILES$. I am thinking of shell process's that might take some significant time to execute and I want my ***Main program*** to monitor that process's output As it executes !. (I am specifically in my projects using ffmpeg & ImageMagick to do conversions, some of those commands can take several seconds and in the case of using ffmpeg to extract Video frames may actually take several minutes to complete !)
I'm currently using a kludge for monitoring ffmpeg frame extractions. I use a SHELL _DONTWAIT than start counting files in the frames output directory. If that count stays Static for 3 seconds then I assume ffmpeg is done !. So far that is working. But I'm concerned that it may not work properly if someone ever runs my app on a slow machine with a Video with VERY LARGE frames !
That works for frame extractions but I also have a couple places in my code where ffmpeg just converts a video and outputs another video ! Counting Files doesn't work in this context and at present I just print an appropriate status message with Please Wait and use a regular Shell command. It would be a nice touch for my software if I could do something like Linux does with Software updates and enable a terminal sub-window in my Main screen showing ffmpeg's output as it proceeds !
I don't expect miracles but I was just thinking that such a function would be useful to have if that was an option that pipecom could encompass !
