"""Type-dependent environment variable value splitting.
Converts a single string into a list of strings. Splits when:
* The ``type_`` is some variant of ``Iterable[pathlib.Path]`` objects.
If Windows, split on ``;``, otherwise split on ``:``.
* Otherwise, if the ``type_`` is an ``Iterable``, split on whitespace.
Leading/trailing whitespace of each output element will be stripped.
This function is the default value for :attr:`cyclopts.App.env_var_split`.
Parameters
----------
type_: type
Type hint that we will eventually coerce into.
val: str
String to split.
delimiter: Optional[str]
Delimiter to split ``val`` on.
If ``None``, defaults to whitespace.
Returns
-------
list[str]
List of individual string tokens.
