PySonar2 is a static analyzer for Python, which does interprocedural analysis to infer types. To understand its properties, please refer to my blog posts:

mvn package

I haven't yet set up releases, so I push working copies of the builds that I don't see problems so far to the target directory as a "stable" version. If the current build is broken or buggy, please grab that snapshot instead. And of course, filing an issue is appreciated.

• Python 2.7.x is recommended (Python <= 2.5 does not work, Python 2.6 works for some people but not all)

• Python 3.x if you have Python3 files

PySonar2 uses CPython interpreter to parse Python code, so please make sure you have python or python3 installed and pointed to by the PATH environment variable. If you have them in different names, please make symbol links.

PYTHONPATH environment variable is used for locating the Python standard libraries. It is important to point it to the correct Python library, for example

export PYTHONPATH=/usr/lib/python2.7

If this is not set up correctly, you may find suboptimal results.

PySonar2 is mainly designed as a library for Python IDEs and other developer tools, so its interface may not be as appealing as an end-user tool, but for your understanding of the library's capabilities, a reasonably nice demo program has been built (all features added by Steve Yegge, all bugs added by Yin Wang).

Now you can build a simple "code-browser" of the Python 2.7 standard library with the following command line:

java -jar target/pysonar-2.0-SNAPSHOT.jar /usr/lib/python2.7 ./html

This will take a few minutes. You should find some interactive HTML files inside the html directory after this process.

PySonar2 doesn't need much memory to do analysis. 1.5Gb is probably enough for analyzing a medium sized project such as Python's standard library or Django. But for generating the HTML files, you may need quite some memory (~2.5Gb for Python 2.7 standard lib). This is due to the highlighting code is putting all code and their HTML tags into the memory.
