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. Click uses parts of optparse written by Gregory P. Ward and maintained by the Python Software Foundation. This is limited to code in parser.py. Copyright 2001-2006 Gregory P. Ward.

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`.

OptionParsera+ The option parser is an internal class that is ultimately used to parse options and arguments. 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``, ``append_const`` or ``count``. The `obj` can be used to identify the option in the order list that is returned from the parser. c s g | ]}t | jqS r )r3 r1 )r r+ rK r r r 4 s z+OptionParser.add_option.<locals>.<listcomp>)r? r( r@ N)r rv updaterF rC rt rD ru ) rH r; r= r> r? r( r@ optionr+ r rK r add_option# s zOptionParser.add_optionra c C s | j t|||d dS )zAdds a positional argument named `dest` to the parser.

The order is a list of objects as they appear on the command line. If arguments appear multiple times they will be memorized multiple times as well.
