psydiff

a structural comparison tool for Python

Psydiff is a structural differencer for Python. It parses Python into ASTs, compare them, and then generate interactive HTML.

Demo

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

http://www.yinwang.org/resources/pydiff1-pydiff2.html

Installation

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

Usage

Just run psydiff.py from the command line:

./psydiff.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.
