ej	e2dQ�dRdS�Z4dS)Zr&a�The context is a special internal object that holds state relevant
    for the script execution at every single level.  It's normally invisible
    to commands unless they opt-in to getting access to it.

    The context is useful as it can pass internal objects around and can
    control special execution features such as reading data from
    environment variables.

    A context can be used as context manager in which case it will call
    :meth:`close` on teardown.

    :param command: the command class for this context.
    :param parent: the parent context.
    :param info_name: the info name for this invocation.  Generally this
                      is the most descriptive name for the script or
                      command.  For the toplevel script it is usually
                      the name of the script, for commands below it it's
                      the name of the script.
    :param obj: an arbitrary object of user data.
    :param auto_envvar_prefix: the prefix to use for automatic environment
                               variables.  If this is `None` then reading
                               from environment variables is disabled.  This
                               does not affect manually set environment
                               variables which are always read.
    :param default_map: a dictionary (like object) with default values
                        for parameters.
    :param terminal_width: the width of the terminal.  The default is
                           inherit from parent context.  If no context
                           defines the terminal width then auto
                           detection will be applied.
    :param max_content_width: the maximum width for content rendered by
                              Click (this currently only affects help
                              pages).  This defaults to 80 characters if
                              not overridden.  In other words: even if the
                              terminal is larger than that, Click will not
                              format things wider than 80 characters by
                              default.  In addition to that, formatters might
                              add some safety mapping on the right.
    :param resilient_parsing: if this flag is enabled then Click will
                              parse without any interactivity or callback
                              invocation.  Default values will also be
                              ignored.  This is useful for implementing
                              things such as completion support.
    :param allow_extra_args: if this is set to `True` then extra arguments
                             at the end will not raise an error and will be
                             kept on the context.  The default is to inherit
                             from the command.
    :param allow_interspersed_args: if this is set to `False` then options
                                    and arguments cannot be mixed.  The
                                    default is to inherit from the command.
    :param ignore_unknown_options: instructs click to ignore options it does
                                   not know and keeps them for later
                                   processing.
    :param help_option_names: optionally a list of strings that define how
                              the default help parameter is named.  The
                              default is ``['--help']``.
    :param token_normalize_func: an optional function that is used to
                                 normalize tokens (options, choices,
                                 etc.).  This for instance can be used to
                                 implement case insensitive behavior.
    :param color: controls if the terminal supports ANSI colors or not.  The
                  default is autodetection.  This is only needed if ANSI
                  codes are used in texts that Click prints which is by
                  default not the case.  This for instance would affect
                  help output.
    :param show_default: Show the default value for commands. If this
        value is not set, it defaults to the value from the parent
        context. ``Command.show_default`` overrides this default for the
        specific command.

    .. versionchanged:: 8.1
        The ``show_default`` parameter is overridden by
        ``Command.show_default``, instead of the other way around.

    .. versionchanged:: 8.0
        The ``show_default`` parameter defaults to the value from the
        parent context.

    .. versionchanged:: 7.1

    .. versionchanged:: 4.0

        it to the current thread local (see :func:`get_current_context`).
        The default behavior of this is to invoke the cleanup functions which
        can be disabled by setting `cleanup` to `False`.  The cleanup
        functions are typically used for things such as closing file handles.

        If the cleanup is intended the context object can also be directly
        used as a context manager.

        Example usage::

            with ctx.scope():
                assert get_current_context() is ctx

        This is equivalent::

            with ctx:
                assert get_current_context() is ctx

        .. versionadded:: 5.0

        :param cleanup: controls if the cleanup functions should be run or
                        not.  The default is to run these functions.  In
                        some situations the context only wants to be
                        temporarily pushed in which case this can be disabled.
                        Nested pushes automatically defer the cleanup.

N)r�)r�r��rvr5r5r6�scope�sz
Context.scopecCs|jS)a�This is a dictionary which is shared with all the contexts
        that are nested.  It exists so that click utilities can store some
        state here if they need to.  It is however the responsibility of
        that code to manage this dictionary well.

        The keys are supposed to be unique dotted strings.  For instance
        module paths are a good choice for it.  What is stored in there is
        irrelevant for the operation of click.  However what is important is
        that code that places data here adheres to the general semantics of
        the system.

        Example usage::

            LANG_KEY = f'{__name__}.lang'

            def set_language(value):
                ctx = get_current_context()
                ctx.meta[LANG_KEY] = value

            def get_language():

        resource's ``__enter__()`` method and returns the result. When

        resource's ``__exit__()`` method.

        To register a cleanup function for something that isn't a
        context manager, use :meth:`call_on_close`. Or use something

        1.  the first argument can be a callback and all other arguments and
            keyword arguments are forwarded directly to the function.
        2.  the first argument is a click command object.  In that case all
            arguments are forwarded as well but proper click parameters
            (options and click arguments) must be keyword arguments and Click
            will fill in defaults.

        Note that before Click 3.2 keyword arguments were not properly filled
        in against the intention of this code and no context was created.  For
        more information about this change and why it was done in a bugfix
        release see :ref:`upgrade-to-3.2`.

dd(�d)d*�Zejejejd+�d,d-�Z dS)4�BaseCommanda�The base command implements the minimal API contract of commands.
    Most code will never use this as it does not implement a lot of useful
    functionality but it can act as the direct subclass of alternative
    parsing methods that do not depend on the Click parser.

    For instance, this can be used to bridge Click and other systems like
    argparse or docopt.

    Because base commands do not implement a lot of the API that other
    parts of Click take for granted, they are not supported for all
    operations.  For instance, they cannot be used with the decorators
    usually and they have no built-in callback system.

    .. versionchanged:: 2.0
       Added the `context_settings` parameter.

    :param name: the name of the command to use unless a group overrides it.
    :param context_settings: an optional dictionary with defaults that are

d�YnXdS)a�This is the way to invoke a script with all the bells and
        whistles as a command line application.  This will always terminate
        the application after a call.  If this is not wanted, ``SystemExit``
        needs to be caught.

        This method is also available by directly calling the instance of
        a :class:`Command`.

        :param args: the arguments that should be used for parsing.  If not
                     provided, ``sys.argv[1:]`` is used.
        :param prog_name: the program name that should be used.  By default
                          the program name is constructed by taking the file
                          name from ``sys.argv[0]``.
        :param complete_var: the environment variable that controls the
                             bash completion support.  The default is
                             ``"_<prog_name>_COMPLETE"`` with prog_name in
                             uppercase.
        :param standalone_mode: the default behavior is to invoke the script
                                in standalone mode.  Click will then
                                handle exceptions and convert them into
                                error messages and the function will never
                                return but shut down the interpreter.  If
                                this is set to `False` they will be
                                propagated to the caller and the return
                                value of this function is the return value
                                of :meth:`invoke`.
        :param windows_expand_args: Expand glob patterns, user dir, and
            env vars in command line args on Windows.
        :param extra: extra keyword arguments are forwarded to the context
                      constructor.  See :class:`Context` for more information.

        .. versionchanged:: 8.0.1
            Added the ``windows_expand_args`` parameter to allow
            disabling command line arg expansion on Windows.

        .. versionchanged:: 8.0
            When taking arguments from ``sys.argv`` on Windows, glob
            patterns, user dir, and env vars are expanded.

    :param epilog: like the help string but it's printed at the end of the
                   help page after everything else.
    :param short_help: the short help to use for this command.  This is
                       shown on the command listing of the parent command.
    :param add_help_option: by default each command registers a ``--help``
                            option.  This can be disabled by this parameter.
    :param no_args_is_help: this controls what happens if no arguments are
                            provided.  This option is disabled by default.
                            If enabled this will add ``--help`` as argument
                            if no arguments are passed
    :param hidden: hide this command from help outputs.

eejd"d#��fd$d%�Z�ZS)(r-a�A multi command is the basic implementation of a command that
    dispatches to subcommands.  The most common version is the
    :class:`Group`.

    :param invoke_without_command: this controls how the multi command itself
                                   is invoked.  By default it's only invoked
                                   if a subcommand is provided.
    :param no_args_is_help: this controls what happens if no arguments are
                            provided.  This option is enabled by default if
                            `invoke_without_command` is disabled or disabled
                            if it's enabled.  If enabled this will add
                            ``--help`` as argument if no arguments are
                            passed.
    :param subcommand_metavar: the string that is used in the documentation
                               to indicate the subcommand place.
    :param chain: if this is set to `True` chaining of multiple subcommands
                  is enabled.  This restricts the form of commands in that
                  they cannot have optional arguments but it allows
                  multiple commands to be chained together.
    :param result_callback: The result callback to attach to this multi
        command. This can be set or changed later with the
        :meth:`result_callback` decorator.
    :param attrs: Other command arguments described in :class:`Command`.

        result callback is already registered this will chain them but
        this can be disabled with the `replace` parameter.  The result
        callback is invoked with the return value of the subcommand
        (or the list of return values from all subcommands if chaining
        is enabled) as well as the parameters as they would be passed
        to the main callback.

        Example::

            @click.group()
            @click.option('-i', '--input', default=23)
            def cli(input):
                return 42

            @cli.result_callback()
            def process_result(result, input):
                return result + input

        :param replace: if set to `True` an already existing result
                        callback will be removed.

    :class:`Option`\s or :class:`Argument`\s.  Other subclasses are currently
    not supported by design as some of the internals for parsing are
    intentionally not finalized.

    Some settings are supported by both options and arguments.

    :param param_decls: the parameter declarations for this option or
                        argument.  This is a list of flags or argument
                        names.
    :param type: the type that should be used.  Either a :class:`ParamType`
                 or a Python type.  The latter is converted into the former
                 automatically if supported.
    :param required: controls if this is optional or not.
    :param default: the default value if omitted.  This can also be a callable,
                    in which case it's invoked when the default is needed
                    without any arguments.
    :param callback: A function to further process or validate the value
        after type conversion. It is called as ``f(ctx, param, value)``
        and must return the value. It is called for all sources,
        including prompts.
    :param nargs: the number of arguments to match.  If not ``1`` the return
                  value is a tuple instead of single value.  The default for
                  nargs is ``1`` (except if the type is a tuple, then it's
                  the arity of the tuple). If ``nargs=-1``, all remaining
                  parameters are collected.
    :param metavar: how the value is represented in the help page.
    :param expose_value: if this is `True` then the value is passed onwards
                         to the command callback and stored on the context,
                         otherwise it's skipped.
    :param is_eager: eager values are processed before non eager ones.  This
                     should not be set for arguments or it will inverse the
                     order of processing.
    :param envvar: a string or list of strings that are environment variables
                   that should be checked.
    :param shell_complete: A function that returns custom shell
        completions. Used instead of the param's type completion if
        given. Takes ``ctx, param, incomplete`` and must return a list
        of :class:`~click.shell_completion.CompletionItem` or a list of
        strings.

    .. versionchanged:: 8.0
        ``process_value`` validates required parameters and bounded
        ``nargs``, and invokes the parameter callback before returning
        the value. This allows the callback to validate prompts.
        ``full_process_value`` is removed.

    .. versionchanged:: 8.0
        ``autocompletion`` is renamed to ``shell_complete`` and has new
        semantics described above. The old name is deprecated and will
        be removed in 8.1, until then it will be wrapped to match the
        new requirements.

    .. versionchanged:: 8.0
        For ``multiple=True, nargs>1``, the default must be a list of
        tuples.

    .. versionchanged:: 8.0
        Setting a default is no longer required for ``nargs>1``, it will
        default to ``None``. ``multiple=True`` or ``nargs=-1`` will
        default to ``()``.

    .. versionchanged:: 7.1
        Empty environment variables are ignored rather than taking the
        empty string value. This makes it possible for scripts to clear
        variables if they can't unset them.

    .. versionchanged:: 2.0
        Changed signature for parameter callback to also be passed the
        parameter. The old callback format will still work, but it will
        raise a warning to give you a chance to migrate the code easier.

        .. versionchanged:: 8.0.2
            Type casting is no longer performed when getting a default.

        .. versionchanged:: 8.0.1
            Type casting can fail in resilient parsing mode. Invalid
            defaults will not prevent showing help text.

        .. versionchanged:: 8.0
            Looks at ``ctx.default_map`` first.

        .. versionchanged:: 8.0
            Added the ``call`` parameter.

    have some extra features that arguments don't have.

    All other parameters are passed onwards to the parameter constructor.

    :param show_default: Show the default value for this option in its
        help text. Values are not shown by default, unless
        :attr:`Context.show_default` is ``True``. If this value is a
        string, it shows that string in parentheses instead of the
        actual value. This is particularly useful for dynamic options.
        For single option boolean flags, the default remains hidden if
        its value is ``False``.
    :param show_envvar: Controls if an environment variable should be
        shown on the help page. Normally, environment variables are not
        shown.
    :param prompt: If set to ``True`` or a non empty string then the
        user will be prompted for input. If set to ``True`` the prompt
        will be the option name capitalized.
    :param confirmation_prompt: Prompt a second time to confirm the
        value if it was prompted for. Can be set to a string instead of
        ``True`` to customize the message.
    :param prompt_required: If set to ``False``, the user will be
        prompted for input only when the option was specified as a flag
        without a value.
    :param hide_input: If this is ``True`` then the input on the prompt
        will be hidden from the user. This is useful for password input.
    :param is_flag: forces this option to act as a flag.  The default is
                    auto detection.
    :param flag_value: which value should be used for this flag if it's
                       enabled.  This is set to a boolean automatically if
                       the option string contains a slash to mark two options.
    :param multiple: if this is set to `True` then the argument is accepted
                     multiple times and recorded.  This is similar to ``nargs``
                     in how it works but supports arbitrary number of
                     arguments.
    :param count: this flag makes an option increment an integer.
    :param allow_from_autoenv: if this is enabled then the value of this
                               parameter will be pulled from an environment
                               variable in case a prefix is defined on the
                               context.
    :param help: the help string.
    :param hidden: hide this option from help outputs.
    :param attrs: Other command arguments described in :class:`Parameter`.

    .. versionchanged:: 8.1.0
        Help text indentation is cleaned here instead of only in the
        ``@option`` decorator.

    .. versionchanged:: 8.1.0
        The ``show_default`` parameter overrides
        ``Context.show_default``.

    .. versionchanged:: 8.1.0
        The default of a single option boolean flag is not shown if the
        default value is ``False``.

    .. versionchanged:: 8.0.1
        ``type`` is detected from ``flag_value`` if given.
