jupyterlab-git

A JupyterLab extension for version control using Git

ui_glow_up

To see the extension in action, open the example notebook included in the Binder demo.

Prerequisites

JupyterLab
Git (version >=2.x)

Usage

Open the Git extension from the Git tab on the left panel

Install

To install perform the following steps:

pip install --upgrade jupyterlab-gitjupyter lab build

Settings

Once installed, extension behavior can be modified via the following settings which can be set in JupyterLab's advanced settings editor:

disableBranchWithChanges: disable all branch operations, such as creating a new branch or switching to a different branch, when there are changed/staged files. When set to true, this setting guards against overwriting and/or losing uncommitted changes.
doubleClickDiff: double click a file in the Git UI to open a diff of the file instead of opening the file for editing.
historyCount: number of commits shown in the history log, beginning with the most recent. Displaying a larger number of commits can lead to performance degradation, so use caution when modifying this setting.
refreshInterval: number of milliseconds between polling the file system for changes. In order to ensure that the UI correctly displays the current repository status, the extension must poll the file system for changes. Longer polling times increase the likelihood that the UI does not reflect the current status; however, longer polling times also incur less performance overhead.
simpleStaging: enable a simplified concept of staging. When this setting is true, all files with changes are automatically staged. When we develop in JupyterLab, we often only care about what files have changed (in the broadest sense) and don't need to distinguish between "tracked" and "untracked" files. Accordingly, this setting allows us to simplify the visual presentation of changes, which is especially useful for those less acquainted with Git.

Troubleshooting

Before consulting the following list, be sure the server extension and the frontend extension have the same version by executing the following commands:

jupyter serverextension listjupyter labextension list

Issue: the Git panel does not recognize that you are in a Git repository.
Possible fixes:
- Be sure to be in a Git repository in the filebrowser tab
- Check the server log. If you see a warning with a 404 code similar to:[W 00:27:41.800 LabApp] 404 GET /git/server_root?1576081660665
  Explicitly enable the server extension by running:
```
jupyter serverextension enable --py jupyterlab_git
```
- If you are using JupyterHub or some other technologies requiring an initialization script which includes the jupyterlab-git extension, be sure to install both the frontend and the server extension before launching JupyterLab.
Issue: the Git panel is not visible.
Possible fixes:
- Check that the JupyterLab extension is installed:
```
jupyter labextension list
```
  If you don't see @jupyterlab/git v... enabled OK in the list, explicitly install the jupyter labextension by running:
```
jupyter labextension install @jupyterlab/git
```

Install

Requires NodeJS

# Install new-ish JupyterLabpip install -U jupyterlab# Clone the repo to your local environmentgit clone https://github.com/jupyterlab/jupyterlab-git.gitcd jupyterlab-git# Install the server extension in development mode and enable itpip install -e .[test]jupyter serverextension enable --py jupyterlab_git --sys-prefix# Build the labextension and dev-mode link it to jlabjlpmjupyter labextension link .

To rebuild the package after a change and the JupyterLab app:

jlpm run buildjupyter lab build

To continuously monitor the project for changes and automatically trigger a rebuild, start Jupyter in watch mode:

jupyter lab --watch

And in a separate session, begin watching the source directory for changes:

jlpm run watch

Now every change will be built locally and bundled into JupyterLab. Be sure to refresh your browser page after saving file changes to reload the extension (note: you'll need to wait for webpack to finish, which can take 10s+ at times).

To execute the tests

pytest jupyterlab_gitjlpm run test
