PyDiff: a structural comparison tool for Python

PyDiff is the forerunner of ydiff, which I implemented around 2011. Later I developed ydiff based on the same algorithm, while supporting multiple languages. Unfortunately I never got a chance to write a Python parser for ydiff. Thus I put the original code for PyDiff here, just in hope it can be useful to someone.

Installation

Copy the whole directory to somewhere in your file system
Add the path to the system's "PATH variable"

Usage

Just run pydiff.py from the command line:

./pydiff.py demos/list1.py demos/list2.py

This will generate a HTML file named list1-list2.html in the current directory. You can then use your browser to open this file and browse around the code.

The HTML is a standalone entity (CSS styles and JavaScript embedded). You can put it anywhere you like and still be able to view it.

Demo

A demo of PyDiff's output (PyDiff diffing itself over a recent big change) can be found here:
