This module defines:

class SubargParser

Parser for structured sub-arguments of argparse arguments. The subarguments can be positional arguments or keyword-arguments, e.g.: myprog.py --print Welcome Message name=Michael role=brother

class SubargAction

Action class to be used with a SubargParser instance. To do so, use arguments action=SubargAction and subarg_parser= when calling add_parameter() method of ArgumentParser.

class SubargHelpFormatter

Formatter for help when using action=SubargAction in add_parameter() of ArgumentParser. Uses SubargHelpFormatterMixin and HelpFormatter to do the actual work.

class SubargHelpFormatterMixin

Mixin for creating formatter classes for use with ArgumentParser when SubargHelpFormatter is not suitable. This could, e.g., be

class MyDefaultsFormatter(
         SubargHelpFormatterMixin, 
         argparse.ArgumentDefaultsHelpFormatter)
    pass

class PSubarg

Positional subarg description with __eq__ operator.

class KWSubarg
