🐞 Path filtering doesn't work about python-toolbox

[tkilias]

it seems it has something to do with generator expressions https://docs.python.org/3/library/functions.html#filter, see the note in the description

An alternative implementation could be

def _matches(file: Path, c: str|Path|re.Pattern):
    if isinstance(c, re.Pattern):
        return c.match(str(file))
    if isinstance(c, Path):
        return str(c) in str(file)
    return c in file.parts


def _accept(file: Path, deny_list: Sequence[str|Path|re.Pattern]) -> Path | None:
    """
    Return ``file`` if none of the specified criteria in Sequence
    ``deny_list`` matches, otherwise return ``None``.
    """
    for criterion in deny_list:
        if _matches(file, criterion):
            return None
    return file


def _deny_filter(files: Iterable[Path], deny_list: Iterable[str]) -> Iterable[Path]:
    return (f for f in files if _accept(f, list(deny_list)))
