ensure_filelike

class gufe.utils.ensure_filelike(fn, mode=None, force_close=False)

Context manager to convert pathlike or filelike to filelike.

This makes it so that methods can allow a range of user inputs.

Parameters:

• fn (PathLike or FileLike) – The user input to normalize.

• mode (str or None) – The mode, if fn is pathlike. If fn is filelike, a warning will be emitted and the mode will be ignored.

• force_close (bool, default False) – Whether to forcibly close the stream on exit. For pathlike inputs, the stream will always be closed. Filelike inputs will close if this parameter is True.
