Setup¶

nbgitpuller is a jupyter serverextension, and hence can be developed locally without needing a JupyterHub.

Fork the nbgitpuller repository and git clone it to your local computer.
Inside the nbgitpuller clone on your local machine, setup a virtual environment to do development in
```
python3 -m venv venv
source venv/bin/activate
```
Install nbgitpuller with its dependencies in this virtual environment
```
pip install -e .
```

Enable the nbgitpuller jupyter serverextension

jupyter serverextension enable --sys-prefix nbgitpuller

Start the notebook server. This will open the classic notebook in your web browser, and automatically authenticate you as a side effect.
```
jupyter notebook
```
You can now test nbgitpuller locally, by hitting the /git-pull url with any of the URL query parameters. For example, to pull the data-8/textbook repository’s gh-pages branch, you can use the following URL:
```
http://localhost:8888/git-sync?repo=https://github.com/data-8/textbook&branch=gh-pages
```
If you make changes to nbgitpuller’s python code, you need to restart the jupyter notebook process (started in step 5) to see your changes take effect. This is not needed if you are only working on the javascript or css.
