[Jython-dev] ANN: First beta release of Jython-2.0

[<bc...@wo...>]

I am happy to announce the first beta release of Jython 2.0. 

Jython is a Java implementation of the Python programming language.  It
allows users to compile Python source code to Java byte codes, and run
the resulting bytecodes on any Java Virtual Machine. It is a very
seamless and smooth integration with Java: from Python you have complete
access to all Java libraries, can build applets, can integrate with Java
beans, and can subclass Java classes in Python and vice versa. Like
Python, and unlike Java, Jython can also be used interactively: just
type some Jython code at the prompt and see the results immediately.

A java installer is available for download at the Jython website:

    http://jython.sourceforge.net/

Installation is started by running the installer class. Further 
information and tips on installation is available at:

    http://jython.sourceforge.net/install.html

Jython 2.0 is feature compatible with Python 2.0 and among the 
new features are:

  - Augmented assignment, e.g. x += 1
  - List comprehensions, e.g. [x**2 for x in range(10)]
  - Extended import statement, e.g. import Module as Name
  - Extended print statement, e.g. print >> file, "Hello"

The changes from alpha 3 include:

  New features
    - Installer logo by Ivan Kougaenko. The logo competition is still 
      open, so submit you suggestions.
    - The default packages selected in the installer are now better
      attuned to the users (as opposed to the jython developers).

  Bug fixes.
    - Fixed a NPE when a class is defined in non-module namespace.
    - Fixed a compilation problem when using JDK1.2.x
    - The installer now creates a useable Uninstall.class.

A complete list of changes and differences are available here:

Cheers,
the jython-developers
