DEPRECATED

This extension is deprecated, please use nbgitpuller instead.

nbpuller

An extension for jupyter notebook to retrieve and update local files from remote git repository using native git pull and merge.

Installation

You can currently install this directly from git:

pip install git+https://github.com/data-8/nbpuller.git
jupyter serverextension enable --py nbpuller
jupyter nbextension install --py nbpuller

To enable this extension for all notebooks:

jupyter nbextension enable --py nbpuller

Usage

nbpuller can be activated through a HTTP GET request to a link in the following format:

<notebook_url>/interact?<settings>

<settings> has the form of URL query strings, with the following possible parameters:

The remote git repo url is constructed as follows: https://<domain>/<account>/<repo>.git

Files or directories at each <path> of the given branch will be retrieved using git.

For example, path=README.md will retrieve a typical README file, while path=labs/ would retrieve a directory called labs in the root of the git repo.

Alternative setting will be:

file_url should be a url. An example is ?file_url=http://localhost/README.md

Configuration

Nbpuller enforces several whitelists for security.

1. File type whitelist for pulling from arbitary url (using file_url option). By default, only ipynb file type is allowed. It can be overriden by ALLOWED_FULETYPES environment variable, delimited by ":".

2. Domain whitelist for pulling from arbitary url. By default none is allowed. Overriden by ALLOWED_URL_DOMAIN variable.

3. Github account whitelist, enforced when pulling from a repo on github. By default, only data-8 is allowed as an account to pull from. This can be overriden by setting ALLOWED_GITHUB_ACCOUNTS variable.

4. Git remote domain whitelist, restricting which domain can the git repo be at. By default, only Github is allowed. This can be overriden by setting ALLOWED_WEB_DOMAINS variable.

Expected behavior

If the destination folder is empty, nbpuller will git clone remote repo.

If the destination folder exist, in general, nbpuller tries to do git pull and merge with -Xours parameter, if necessary. In the case that there is any change in the folder, nbpuller will git add all of them and commit them, before pulling and merging.

After files are ready, user will receive a HTTP redirect to the file tree at the last path downloaded. In case error, the user will stay at the initial page and see an error output.
