# Jupyter Notebook PyFilesystem Contents Manager

[![Build Status](https://travis-ci.com/manics/jupyter-pyfilesystem.svg?branch=master)](https://travis-ci.com/manics/jupyter-pyfilesystem)

[![PyPI](https://img.shields.io/pypi/v/jupyter-pyfilesystem)](https://pypi.org/project/jupyter-pyfilesystem/)

A [Jupyter Notebooks `ContentsManager`](https://jupyter-notebook.readthedocs.io/en/stable/extending/contents.html#writing-a-custom-contentsmanager) that uses [PyFilesystem](https://www.pyfilesystem.org/) for storing files.

Includes a compatible [`Checkpoints`](https://jupyter-notebook.readthedocs.io/en/stable/extending/contents.html#customizing-checkpoints) class.

## Installation

```

pip install jupyter-pyfilesystem

```

## Example

`jupyter_notebook_config.py`:

```python

c.NotebookApp.contents_manager_class = 'jupyter_pyfilesystem.FsContentsManager'

# In-memory temporary filesystem

c.FsContentsManager.fs_url = 'mem://'

```

See https://docs.pyfilesystem.org/en/latest/openers.html for information on how to define `fs_url`, and https://docs.pyfilesystem.org/en/latest/builtin.html for a list of built-in filesystems.

There are also several externally-contributed filesystems that can be used.

Some are listed on https://www.pyfilesystem.org/page/index-of-filesystems/

Note some filesystems may not behave as you expect.

For example, the curent implementations of the `zip://` and `tar://` filesystems do not allow you to update an existing file.

You can only create/overwrite an existing file, or open a file read-only.

For example:

```python

c.FsContentsManager.fs_url = 'zip:///tmp/test.zip'

import os

if os.path.exists(fs_url[6:]):

    c.FsContentsManager.create = False

    c.FsContentsManager.writeable = False

```

If you are using a remote filesystem you may want to enable the `keepalive`.

For example, this will make a remote request to get the details of `/` every 60 seconds:

```python

c.FsContentsManager.keepalive = 60

```
