Parsing a commandline from within Python


I am writing a commandline tool in Python which is often feed with lots of commandline arguments. In practice, the commandline already reached a critical length which is to long for Windows (some versions of Windows only support commandlines of up to 2047 characters). To work around this problem, wethought up the idea of bypassing the commandline into a file and then letting Python parse the content of the file the same way, the arguments in sys..argv are parsed.

Is there any buildin function which mimics the behavior of the standard commandline parser (generating a list of strings "foo bar" and "some text" from the commandline <"foo bar" "some text">)?

If not, do you have any other ideas how to handle this problem (increasing commandline length, xml files might be a way)?

Try the shlex module::
>>import shlex
shlex.split('"foo bar" "some text"')
['foo bar', 'some text']
