fs.wrap¶
Collection of useful WrapFS
subclasses.
Here’s an example that opens a filesystem then makes it read only:
>>> from fs import open_fs
>>> from fs.wrap import read_only
>>> projects_fs = open_fs('~/projects')
>>> read_only_projects_fs = read_only(projects_fs)
>>> read_only_projects_fs.remove('__init__.py')
Traceback (most recent call last):
...
fs.errors.ResourceReadOnly: resource '__init__.py' is read only

WrapCachedDir
(wrap_fs)¶ Caches filesystem directory information.
This filesystem caches directory information retrieved from a scandir call. This may speed up code that calls
isdir
,isfile
, orgettype
too frequently.Note
Using this wrap will prevent changes to directory information being visible to the filesystem object. Consequently it is best used only in a fairly limited scope where you don’t expected anything on the filesystem to change.

WrapReadOnly
(wrap_fs)¶ Makes a Filesystem read-only.
Any call that would would write data or modify the filesystem in any way will raise a
ResourceReadOnly
exception.
