PySonar2 - an advanced static analyzer for Python

How to build

PySonar 1.0 was part of Jython, and PySonar2 still depend on Jython's parser (the situation may change soon). So you need to download Jython's source code and compile PySonar2 with it.

the easy way

To make this process easier, I made a shell script. So you can just run

./build.sh

It will automatically download Jython and do all the set up for you. It should tell you what's going on what to do next. If it doesn't work, look at the rest of the this section for manual steps, otherwise you are done.

the harder way (read only if you fail the easy way)

1. Download Jython

    hg clone http://hg.python.org/jython
   

2. Checkout this repo, replace everything inside src/org/python/indexer (which is PySonar 1.0) with the content of this repo

3. Delete the tests for the old indexer

    rm -rf tests/java/org/python/indexer
   

4. Build Jython

    ant jar-complete
   

5. Finished. PySonar2 is now inside dist/jython.jar.

How to run?

PySonar2 is mainly designed as a library for Python IDEs and other tools, but for your understanding of the library's usage, a demo program is built (most credits go to Steve Yegge). To run it, use the following command line:

java -classpath dist/jython.jar org.python.indexer.demos.HtmlDemo /usr/lib/python2.7 /usr/lib/python2.7

You should find some interactive HTML files inside the html directory generated after this process.

Note: PySonar2 doesn't need much memory to do analysis (1GB is probably enough), but for generating the HTML files, you may need a lot of memory (~4GB for Python 2.5 standard lib). This is due to the highlighting I added without using more sophisticated ways of doing it. The situation may change soon.
