I am trying to use a command line program called foma (http:// code.google.com/p/foma/) from one of my Pylons application's controllers. I need to use the program to generate a binary file. The following Python script generates the file I expect. This script opens the foma program and runs two commands: the first loads a human- readable file ('source phonology.foma') and the second writes the binary file ('save stack phonology_bin.foma').
import subprocess process = subprocess.Popen(['foma'], stdin=subprocess.PIPE, stdout=subprocess.PIPE) result = process.communicate('source phonology.foma\nsave stack phonology_bin.foma\n')[0] However, if I run the exact same three lines of code *from within* a Pylons controller, a phonology_bin.foma file is still generated but it is not the file I expect. Note that the incorrect/unexpected binary file generated *is* a valid foma file, it is just not the one I expect, i.e., it is not the one generated by running the Python script from the command line. Can somebody enlighten me as to what might be the cause of this discrepancy? Or (perhaps better) could someone point me towards a better strategy for solving this problem?
