command line utility for cups

[Brian Oney]

Dear all,

I am having trouble with argparse. I am trying to translate the following line to a sleek python
script:

lpr -o media=legal -o sides=two-sided-long-edge filename

Now where I am.

import argparse
parser = argparse.ArgumentParser(description='Print stuff with cups')
parser.add_argument('--printer', '-p',
                    help='Use this printer, try running: lpstat -a')
parser.add_argument('--options', '-o', 
                    help='Options for this printer, try running: \
                    lpoptions -p PRINTER -l')

parser.parse_known_args(['-o', 'sides=one-sided', '-o', 'test=crap'])
Namespace(options='test=crap', printer=None))

How should I deal with multiple options being fed into my script?

Thanks!

Cheers,
Brian

Try action="append". You may also provide a type=split_func argument to
split the key=value pairs:

>>> import argparse
>>> parser = argparse.ArgumentParser()
>>> parser.add_argument("-o", action="append", type=lambda p: p.split("=",
1))
_AppendAction(option_strings=['-o'], dest='o', nargs=None, const=None,
default=None, type=<function <lambda> at 0x7feef70a8510>, choices=None,
help=None, metavar=None)
>>> parser.parse_args(["-o", "a=b", "-o", "c=d"])
Namespace(o=[['a', 'b'], ['c', 'd']])

Hi,
You can also try click library from pypi, that is a very good command line
stuff.

Thanks Peter!

That's pretty slick.

I will get it working for sure now.

Thank you for the tip. I am away of click and it's awesomeness, but am hesitant because it's not apart of stdlib. I have gotten bitten too often.
