I am trying to capture the stdin and stdout from runProcess into a string for analysis.
However, setting up the handles seems to be rather difficult. I wandered into GHC.IO.Handle, and that seems to be the logical destination, but it seems that this should be very simple.
If you don’t need to communicate with the process interactively, the easiest method is to use
readProcess:Otherwise, look at
runInteractiveProcess– it starts the process and creates pipes that you can write to and read from with e.g.hPutStr/hGetLine.
