pip-viz 0.0.7

A package that generates a graph of dependencies using Graphviz

pip-viz

A script that generates an SVG image displaying the dependencies within a pip virtual environment.

Installation

pip-viz uses graphviz Python library to generate a .gv file containing instructions written in Graphviz's DOT language. The Graphviz application takes the instructions written in the .gv file and generates an image.

The Graphviz application will need to be installed separately. Linux, Windows, and Mac versions are available and the graphviz executable dot will need to be on your PATH.

With your virtualenv active, install from the Python Package Index (PyPI) with the following command:

pip install pip-viz

Once installed, use the pip-viz executable to render a diagram for the current virtualenv. The syntax for this command is:

pip-viz my_app_dependencies

This command will generate two files in the current working directory:

• my_app_dependencies.gv - The file that defines the graph in the DOT language
• my_app_dependencies.gv.svg - An SVG image that you can view in your web browser. You can use the zoom, scroll, and find features of your browser to navigate the diagram.

By default, pip-viz and it's dependencies as well as packages that are present in a newly created virtualenv will be ignored unless:

1. The package is a dependency of a package which is not ignored
2. The -a (or --all) command line flag is used.
