Hi, I'm impletting a tool in Python. I'd like this tool to behave like a standard unix tool, as grep for exemple. I chose to use the argparse module to parse the command line and I think I'm getting into several limitations of this module.
> First Question. How can I configure the the ArgumentParser to allow the user to give either an input file or to pipe the output from another program? $ mytool.py file.txt $ cat file.txt | mytool.py > Second Question. How can I get the nargs options working with subparser? Cause basically if I've got a positionnal argument with nargs > 1, then the subparsers are recognized as values for the positionnal argument. $ mytool.py file1.txt file2.txt foo Here foo is a command I'd like to pass to mytool but argparse considers it's another input file (as are file1.txt and file2.txt). Any help would be appreciated. Ben. -- http://mail.python.org/mailman/listinfo/python-list
