Jython and Groovy

Groovy is still getting all the hype at the moment, but Jython is still very much in the picture. In fact, I hope and expect that they'll both succeed. Both get a flattering mention in Extend your Java Application with Embedded Languages.

On the Jython side, the Jython site is now indicating a major Summer release, just as Samuele said in April. Also, I hear from Jez that the Sun boys are planning to make some changes to the JVM to make continuations easier to implement in Groovy. Might this make generators easier to implement in Jython? Perhaps Samuele should get in touch with James...

Also, IBM's developerWorks is running a new series, alt.lang.jre, covering alternate JVM languages. The first article, Get to know Jython, in a nice little intro into, uh, well, I suppose you can work out what it's about for yourself. ;-) I wouldn't be surprised if a Groovy article isn't to far behind.

Getting all the hype or not, I can see that Groovy is getting a JSR - http://www.jcp.org/en/jsr/detail?id=241

My quick summary of Java scripting languages:

:-( can't create classes

:) concise regular-expression handling
:-( can't shortcut .getFoo() to .foo
:-( can't concatenate strings and numbers directly

:) concise regular-expression handling
:-( filename must be valid class name
:-( can't use Java prior to 1.4

:) whitespace defines blocks - concise
:-( creates a bunch of *$py.class files
:-( no boolean type
:-( can't concatenate strings and numbers directly
