BeanShell - Simple Java Scripting

What kind of new language features are you experimenting with?

Language visualization. I am tracing execution of the code to help 
present and edit it. There are several other research projects here that 
needed to instrument Java code - they did it in various laborious ways. 
Hacking an interpreter is so much easier. If 2.0 gets to the point where 
it is really 100% Java-compatible it will be useful in research.

BTW, I am considering Jedit for the GUI side of my work. Eclipse is the 
alternative. Jedit looks so much simpler and cleaner. But, as I am sure 
you are painfully aware of, Eclipse has become just incredibly popular.

Hi Jonathan,

I am highly interested in language visualisation too.

I am mainly interested in graphical visualisation of object oriented and
structured programming concepts. 
I intend to derive JHotDraw for my visualisations. JEdit or Eclipse are of
no use to me. I need something lean, because I want to integrate my visualisations
into web-based online tutorials.

I think we may have similar needs regarding the accessibility of BeanShell
such as 1) access to the name space, 2) to the execution stack and 3) to
the tokens (for coloring the source code).

If you happen to have these needs too, I wonder if you (or other people on
this list) could share some ideas, on how to achieve this. i.e. is this possible
by subclassing some of the BeanShell classes, or does this require a minor
(or a major) rewrite of BeanShell?
