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.
- Copy the whole directory to somewhere in your file system
- Add the path to the system's "PATH variable"
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.
A demo of PyDiff's output (PyDiff diffing itself over a recent big change) can be found here:
