mmeval.fileio.list_dir_or_file

mmeval.fileio.list_dir_or_file(dir_path: Union[str, pathlib.Path], list_dir: bool = True, list_file: bool = True, suffix: Optional[Union[str, Tuple[str]]] = None, recursive: bool = False, backend_args: Optional[dict] = None) → Iterator[str]

Scan a directory to find the interested directories or files in arbitrary order.

Note

list_dir_or_file() returns the path relative to dir_path.

Parameters

• dir_path (str or Path) – Path of the directory.

• list_dir (bool) – List the directories. Defaults to True.

• list_file (bool) – List the path of files. Defaults to True.

• suffix (str or tuple[str], optional) – File suffix that we are interested in. Defaults to None.

• recursive (bool) – If set to True, recursively scan the directory. Defaults to False.

• backend_args (dict, optional) – Arguments to instantiate the corresponding backend. Defaults to None.

Yields

Iterable[str] – A relative path to dir_path.

Examples

>>> dir_path = '/path/of/dir'
>>> for file_path in list_dir_or_file(dir_path):
...     print(file_path)
>>> # list those files and directories in current directory
>>> for file_path in list_dir_or_file(dir_path):
...     print(file_path)
>>> # only list files
>>> for file_path in list_dir_or_file(dir_path, list_dir=False):
...     print(file_path)
>>> # only list directories
>>> for file_path in list_dir_or_file(dir_path, list_file=False):
...     print(file_path)
>>> # only list files ending with specified suffixes
>>> for file_path in list_dir_or_file(dir_path, suffix='.txt'):
...     print(file_path)
>>> # list all files and directory recursively
>>> for file_path in list_dir_or_file(dir_path, recursive=True):
...     print(file_path)
