Version number: Version 1.77 (Sep 9 2020)
Author: Andy Bulka
Reverse engineer Python source code into UML class diagrams.
Installation / Usage
Pynsource binary app installers for Mac / Windows / Linux - see Downloads
An affordable, commercial Pro Edition is also available with extra features like zoom and the ability to drag to connect shapes.
To run from source code
python3, specifically Python 3.7 or later installed (Linux can use Python 3.6). You also need
pip3 (which should come with Python 3), then simply:
$ git clone https://github.com/abulka/pynsource.git $ cd pynsource $ pip3 install -r requirements.txt $ ./bin/run (Mac, Linux) or $ .\bin\run-win10.bat (Windows 10)
Linux Users: Please use the script
bin/install-linux-18.04 to pip install needed Ubuntu dependencies, including a wxPython wheel specific to
Ubuntu 18.04. Use the script
bin/install-linux-20.04 if you are installing on
Ubuntu 20.04. If you are using a different
version of Ubuntu simply edit the script to change the url of wxpython accordingly.
The GUI toolkit wxpython that
Pynsource relies on needs a ‘proper’ framework Python environment to run in, which means no virtual environments - use your main Python e.g. brew Python on a Mac or an official install from python.org for Windows 10. The default Python 3 on Ubuntu 18.04 is fine too.
However I've recently discovered that you can use a pyenv framework Python environment for building and running Pynsource, see this issue for more info on how to do this. E.g.
PYTHON_CONFIGURE_OPTS="--enable-framework" pyenv install 3.8.6.
Or simply use the prebuilt binaries executables listed above!
- Generates UML diagrams from Python 3 or legacy Python source code

Examples of PlantUML view:
Note: PlantUML view requires an internet connection.
What does Pynsource mean?
Py = Python N = and Source = Source code
Long Answer: Since it was built in Australia, which is famous for its meat pies and sauce at football matches, Pie-and-Sauce. Where Py = Python and Source = source code.

Help is built into the app - hit
View a Youtube video tutorial on the basic usage of Pynsource (pro edition is featured).

Run your own PlantUML server
When using PlantUML view (which is not necessary to use the app), if you want to run your own PlantUML server (faster, larger diagrams, more secure), see the Pynsource built in help for installation and configuration instructions.
Support the project
Help support the project by purchasing a Pro Edition license which contains extra features. Future plans include undo/redo, recognition of Python type annotations, line labels, module and package visualisation.
Running the tests
Download the source code, install the dependencies (see above) then
./bin/testall (Mac, Linux) or .\bin\testall-win10.bat (Windows 10)
from the root of the project. You may need to alter the version of Python being invoked by the script e.g.
The environment variable
TRAVIS is set by the script to avoid tests that involve loading the wxPython package - this is especially needed on Travis and GitHub actions. It may also not be possible on your machine if you are running certain Python environments e.g. I had a problem with a framework pyenv install on my Mac running any tests that imported
wx, even though Pynsource itself ran OK. P.S. The subset of packages
requirements-travis.txt is all you need to run the tests, and these exclude wx.
Alternatively you can also run all the tests by
cd src then
./bin/testall (because there is a testall script both in ./bin/ and in src/bin - for Mac/Linux, anyway).
