As the + example above shows, the add_argument() method is used to populate + the parser with actions for optional and positional arguments. Then + the parse_args() method is invoked to convert the args at the + command-line into an object with attributes. + + - ArgumentError -- The exception raised by ArgumentParser objects when + there are errors with the parser's actions. Errors raised while + parsing the command-line are caught by ArgumentParser and emitted + as command-line messages. + + - FileType -- A factory for defining types of files to be created. As the + example above shows, instances of FileType are typically passed as + the type= argument of add_argument() calls. + + - Action -- The base class for parser actions. Typically actions are + selected by passing strings like 'store_true' or 'append_const' to + the action= argument of add_argument(). However, for greater + customization of ArgumentParser actions, subclasses of Action may + be defined and passed as the action= argument. + + - HelpFormatter, RawDescriptionHelpFormatter, RawTextHelpFormatter, + ArgumentDefaultsHelpFormatter -- Formatter classes which + may be passed as the formatter_class= argument to the + ArgumentParser constructor. HelpFormatter is the default, + RawDescriptionHelpFormatter and RawTextHelpFormatter tell the parser + not to change the formatting for help text, and + ArgumentDefaultsHelpFormatter adds information about argument defaults + to the help. + +All other classes in this module are considered implementation details. +(Also note that HelpFormatter and RawDescriptionHelpFormatter are only +considered public as object names -- the API of the formatter objects is +still considered an implementation detail.) +""" + +__version__ = '1.1' +__all__ = [ + 'ArgumentParser', + 'ArgumentError', + 'ArgumentTypeError', + 'BooleanOptionalAction', + 'FileType', + 'HelpFormatter', + 'ArgumentDefaultsHelpFormatter', + 'RawDescriptionHelpFormatter', + 'RawTextHelpFormatter', + 'MetavarTypeHelpFormatter', + 'Namespace', + 'Action', + 'ONE_OR_MORE', + 'OPTIONAL', + 'PARSER', + 'REMAINDER', + 'SUPPRESS', + 'ZERO_OR_MORE', +] + +import re as _re +import sys as _sys +import warnings +from gettext import gettext as _, ngettext + +from sanic.log import logger + +SUPPRESS = '==SUPPRESS==' + +OPTIONAL = '?' +ZERO_OR_MORE = '*' +ONE_OR_MORE = '+' +PARSER = 'A...' +REMAINDER = '...' +_UNRECOGNIZED_ARGS_ATTR = '_unrecognized_args' + + +class PrintMessage(Exception): + ... + + +# ============================= +# Utility functions and classes +# ============================= + +class _AttributeHolder(object): + """Abstract base class that provides __repr__. + + The __repr__ method returns a string in the format:: + ClassName(attr=name, attr=name, ...) + The attributes are determined either by a class-level attribute, + '_kwarg_names', or by inspecting the instance __dict__. + """ + + def __repr__(self): + type_name = type(self).__name__ + arg_strings = [] + star_args = {} + for arg in self._get_args(): + arg_strings.append(repr(arg)) + for name, value in self._get_kwargs(): + if name.isidentifier(): + arg_strings.append('%s=%r' % (name, value)) + else: + star_args[name] = value + if star_args: + arg_strings.append('**%s' % repr(star_args)) + return '%s(%s)' % (type_name, ', '.join(arg_strings)) + + def _get_kwargs(self): + return list(self.__dict__.items()) + + def _get_args(self): + return [] + + +def _copy_items(items): + if items is None: + return [] + # The copy module is used only in the 'append' and 'append_const' + # actions, and it is needed only when the default value isn't a list. + # Delay its import for speeding up the common case. + if type(items) is list: + return items[:] + import copy + return copy.copy(items) + + +# =============== +# Formatting Help +# =============== + + +class HelpFormatter(object): + """Formatter for generating usage messages and argument help strings. + + Only the name of this class is considered a public API.
