ANN: JRuby beta 1.6/0.5.1

Proudly announcing a new version of JRuby:

JRuby (http://jruby.sf.net) is a pure Java implementation of the Ruby
interpreter, being developed by a team lead by Jan Arne Petersen.

JRuby is free software released under the GNU General Public License.

JRuby is tightly integrated with Java to allow both to script any Java
class and to embed the interpreter into any Java application.

Since our latest release in May we have made lots of progress. All of
this is in our new beta release 1.6/0.5.1, available at
http://sourceforge.net/project/showfiles.php?group_id=35413&release_id=104911

Note: JRuby is still BETA software. In particular, the thread support
may (will) have bad interactions with other threads when JRuby is
embedded.

Changes since 1.6/0.5.0:

* Improved support for built-in classes.
* Speed improvements.
* Better Java-Ruby support.
* Memory management improvements.
* New start script.
* Lots of bug fixes.

Regards
The JRuby Team

Pardon my ignorance about this project…

Which, if any, of the following are possible
with JRuby?

  1. Compile a Ruby program to Java bytecodes
  2. Add a Swing-based GUI to a Ruby program
  3. Write an applet in Ruby which will then
    run on a browser with a JVM

Just curious.

Thanks,
Hal

Not yet, but we hope to do this sooner or later.

Yes, there is even a small example of this included.

  1. Write an applet in Ruby which will then
    run on a browser with a JVM

I think it would require bytecode compilation to create an applet
directly. But it should be possible to write some kind of launcher
applet that loads and runs a script.

Please do tell us if you write one! :slight_smile:
