class documentation

The default behavior of Click is to apply a type on a value directly. This works well in most cases, except for when `nargs` is set to a fixed count and different types should be used for different items. In this case the :class:`Tuple` type can be used. This type can only be used if `nargs` is set to a fixed number. For more information see :ref:`tuple-type`. This can be selected by using a Python tuple literal as a type. :param types: a list of types that should be used for the tuple items.

Inherited from ParamType (via CompositeParamType):

Method __call__ Undocumented
Method fail Helper method to fail with an invalid value message.
Method get_metavar Returns the metavar default for this param if it provides one.
Method get_missing_message Optionally might return extra information about a missing parameter.
Method shell_complete Return a list of :class:`~click.shell_completion.CompletionItem` objects for the incomplete value. Most types do not provide completions, but some do, and this allows custom types to provide custom completions as well.
Method split_envvar_value Given a value from an environment variable this splits it up into small chunks depending on the defined envvar list splitter.

Parameters
types:t.Sequence[t.Union[t.Type, ParamType]]Undocumented
def convert(self, value, param, ctx): (source)

Convert the value to the correct type. This is not called if the value is ``None`` (the missing value). This must accept string values from the command line, as well as values that are already the correct type. It may also convert other compatible types. The ``param`` and ``ctx`` arguments may be ``None`` in certain situations, such as when converting prompt input. If the value cannot be converted, call :meth:`fail` with a descriptive message. :param value: The value to convert. :param param: The parameter that is using this type to convert its value. May be ``None``. :param ctx: The current context that arrived at this value. May be ``None``.

Parameters
value:t.AnyUndocumented
param:t.Optional[Parameter]Undocumented
ctx:t.Optional[Context]Undocumented
Returns
t.AnyUndocumented
def to_info_dict(self): (source)

Gather information that could be useful for a tool generating user-facing documentation. Use :meth:`click.Context.to_info_dict` to traverse the entire CLI structure. .. versionadded:: 8.0
