# Jupyter helpers for IPython

[![flake8](https://github.com/krassowski/jupyter-helpers/workflows/Flake8/badge.svg)](https://github.com/krassowski/jupyter-helpers/actions?query=workflow%3A%22flake8%22)

[![pypi-version](https://img.shields.io/pypi/v/jupyter-helpers.svg)](https://python.org/pypi/jupyter-helpers)

This collection of IPython helpers optimized for JupyterLab users will help you to:

- Play a sound once the computations have finished (or failed)

- Integrate the notifications with your OS (ready for GNOME shell)

- Enable auto-completion for rpy2 (great for using  ggplot2!) - now also available in [jupyterlab-lsp](https://github.com/krassowski/jupyterlab-lsp)

- Summarize dictionaries and other structures in a nice table

- Selectively import from other notebooks

- Scroll to the recently executed cell on error or when opening the notebook

- Use interactive (following) tail for long outputs

The examples are available in [demos](https://github.com/krassowski/jupyter-helpers/tree/master/demos) directory. Please, see the [Productivity tips for Jupyter (Python)](https://medium.com/@krassowski.michal/productivity-tips-for-jupyter-python-a3614d70c770) article for introduction and more code samples. For jump-to-definition feature, please visit [jupyterlab-lsp](https://github.com/krassowski/jupyterlab-lsp).

### Installation

```bash

pip3 install "jupyterlab>=3" jupyter_helpers ipywidgets

```

To use advanced GNOME integration,

run `setup.sh` script from the installation directory (PRs welcome to propose a better setup procedure).

To check if you have required system libraries for the better GNOME integration, see [notify-send.sh repository](https://github.com/vlevit/notify-send.sh).

### Showcase

#### Notifications

Note: this implementation is IPython-specific and limitted to GNOME. For a universal implementation of JupyterLab notifications checkout: https://github.com/mwakaba2/jupyterlab-notifications

#### Tailing outputs

#### Auto-completion in R cells
