Overview

This repo contains a set of Jupyter Notebook plugins that enable interop with pex and pants.

Installation

To install this plugin, simply invoke pip install like so:

pip install pants-jupyter-plugin

Plugin Loading

To load the plugin in your Jupyter Notebook environment, use the %load_ext command in a Notebook cell like so:

%load_ext pants_jupyter_plugin

Magics

This package provides 3 primary magics for python environment loading from pex and/or pants targets. All of these will scrub and replace the existing sys.path/environment so it's best to do this before you import any modules to avoid cached imports.

%pex_load

This magic allows you to load an existing pex file that exists on disk into the python environment.

Usage:

%pex_load <path to pex file>

%requirements_load

This magic allows you to load a transitive closure of arbitrary requirements into the environment using pex(1).

Usage:

%requirements_load <requirements>

%pants_load

This magic allows you to build and load a pants python_binary target into the environment. It works in conjunction with the %pants_repo magic, which is how you point the plugin to a given pants-compatible repo.

%pants_repo <path to pants repo>
...
%pants_load <pants target>
