"""Parse `argv` based on command-line interface described in `doc`.
|
|
||||||
|
|
||||||
`docopt` creates your command-line interface based on its
|
|
||||||
description that you pass as `doc`. Such description can contain
|
|
||||||
--options, <positional-argument>, commands, which could be
|
|
||||||
[optional], (required), (mutually | exclusive) or repeated...
|
|
||||||
|
|
||||||
Parameters
|
|
||||||
----------
|
|
||||||
doc : str
|
|
||||||
Description of your command-line interface.
|
|
||||||
argv : list of str, optional
|
|
||||||
Argument vector to be parsed. sys.argv[1:] is used if not
|
|
||||||
provided.
|
|
||||||
help : bool (default: True)
|
|
||||||
Set to False to disable automatic help on -h or --help
|
|
||||||
options.
|
|
||||||
version : any object
|
|
||||||
If passed, the object will be printed if --version is in
|
|
||||||
`argv`.
|
|
||||||
options_first : bool (default: False)
|
|
||||||
Set to True to require options precede positional arguments,
|
|
||||||
i.e. to forbid options and positional arguments intermix.
|
|
||||||
|
|
||||||
Returns
|
|
||||||
-------
|
|
||||||
args : dict
|
|
||||||
A dictionary, where keys are names of command-line elements
|
|
||||||
such as e.g. "--verbose" and "<path>", and values are the
|
|
||||||
parsed values of those elements.
|
|
||||||
|
|
||||||
Example
|
|
||||||
-------
|
|
||||||
>>> from docopt import docopt
