Yeah, I'm doing that by default. The problem in my actual program is
that the user can change the latex command and the compiler options, so
I can't guarantee that the latex compiler is being run in batchmode or
nonstopmode (The user might screw up). So, ideally, I want to enforce
that the subprocess is non-interactive by trowing an exception if it
does ask for input.
I have to use subprocess instead of os.system because I want to filter
the output (colorize it, parse for warnings, etc.)
Thanks,
Michael
