The plan is to remove more and more from here over time. The reason this is a different module and not optparse from the stdlib is that there are differences in 2.x and 3.x about the error messages generated and optparse in the stdlib uses gettext for no good reason and might cause us issues. � N)�deque� )� UsageError� NoSuchOption�BadOptionUsage�BadArgumentUsagec s� t ���t |�}g }d��fdd�� |r�� |�}|dkrH|�� ��� q$|dkr�� �fdd�t|�D �}�dk rx|�� |�t|�� q$|dk r$�dk r�td��t|��|�d� q$�dk r�t��|�< g �t|�d d� �|�d d�< t|�t��fS ) a� Given an iterable of arguments and an iterable of nargs specifications, it returns a tuple with all the unpacked arguments at the first index and all remaining arguments as the second. The nargs specification is the number of arguments that should be consumed or `-1` to indicate that this position should eat up all the remainders. Missing items are filled with `None`.

It's modelled after optparse and brings a similar but vastly simplified API. It should generally not be used directly as the high level Click classes wrap it for you. It's not nearly as extensible as optparse or argparse as it does not implement features that are implemented on a higher level (such as types or defaults). :param ctx: optionally the :class:`~click.Context` where this parser should go with.

The destination is not inferred (unlike with optparse) and needs to be explicitly provided. Action can be any of ``store``, ``store_const``, ``append``, ``appnd_const`` or ``count``. The `obj` can be used to identify the option in the order list that is returned from the parser.
