Open Source Software in Python

Open Source Ajax Frameworks

Open Source Aspect-Oriented Frameworks in Python

  • Aspects.py - aspects.py library provides means to intercept function calls. Functions and methods (also in Python standard library and third party code) can be wrapped so that when they are called, the wrap is invoked first. Depending on the wrap, the execution of the original function can be omitted, or the function can be called arbitrarily many times. Wraps are able to modify the arguments and the return value of the original function. In the terminology of aspect-oriented programming, the library allows applying advices (wraps) to call join points of methods and functions in around fashion.

     * extensibility - PyBlosxom has a plugin framework allowing you to build plugins in Python to augment and change PyBlosxom's default behavior.
     * community - There are hundreds of PyBlosxom users out there all of whom have different needs. PyBlosxom is used on a variety of operating systems in a variety of environments. The pyblosxom users list shares their experiences, plugins, and expertise. PyBlosxom runs as a CGI script, under Paste, and as a WSGI
