The problem with the generic script container which is using BSF is that its
quite limited as to what it can do with introspection. For example, I'm
don't think it can get at the attr_writer variables in Ruby so it can't
support Ruby introspection the way the C++ Ruby container does, and there's
probably similar problems with other languages. I also couldn't see how to
get it to work with scopes properly without using a new BSFManager for each
instance which means recompiling the script for each instance which is a bit
inefficient. So at least for now I think it is useful to keep the langauge
specific containers (i've just added a rhino one to the sandbox).

What i'd like to do now is just implement a few containers and get support
for all the things like scopes, lifecycle, async, properties and references
working so we can clearly see what code can be made common. If you'd like to
do Ruby or add support for something like async or component lifecylces that
would be great.

Hi Ant,

Sequel to our last chat over IRC I took a look at your Sandbox.  I am able
to understand all of what you have done there.  A couple of thoughts /
questions ...
- So would it be that we just have this one 'ScriptContainer' that will
take
care of javascript, ruby, groovy.
- Would it be good to have a Script Registry (like the wsdl registry and
so
on) that would have compiled scripts.  So given a script source one can
get
a BSFEngine from the registry.  But then what about the context info
(properties and references) - how do we set them in a 'flyweight' way?
- What do we do about introspectable component type info?  Should we have
an
interface for which we will have implementations for various script types?

Please let me know your thoughts on the next steps with the Sandbox stuff
and what I can help you out with?

Thanks

- Venkat
