Transforming Java -> Smalltalk

Hello,

I want to transform a bunch of Java classes (source available) to
Smalltalk. SmaCC includes an example java parser, but I'm curious to
know if someone has already done some kind of transformer that creates
Smalltalk source code. The output can be incomplete, I just want to
avoid transforming the boring parts that can be automated.

Holger,

Some time ago there was a project called Frost which permitted to load Java
code into VisualWorks. The sources of that project are available in the
Cincom Public Store Repository. Certainly the status is far away from
production quality, but maybe it can help you.

alexandre bergel parsed and could script some java code with Smacc  
and the Java parser.
Contact him.

Hi,

Maybe this can help you:
We're not transforming any Java code into Smalltalk code, but we're  
manipulating Java code represented by Eclipse parsetrees directly in  
a bunch of Smalltalk tools. The Eclipse parser and its parsetree are  
made available in Smalltalk through a Java<->Smalltalk  
interconnection library called JavaConnect (similar to JNIPort). I  
don't know how easy it would work using JNIPort because Eclipse is  
quite ugly with its specific classloader requirement etc, but we're  
about to make JavaConnect public too.

Our goal for doing this was exactly to avoid having to write Java-
parsing and -analysis tools in Smalltalk and still be able to operate  
on Java code from within a Smalltalk environment. So, if you want to  
have a full Eclipse parsetree available from within Smalltalk, from  
where you can start doing transformation, just drop me a note. We  
will also send an email in the next few weeks when we make all the  
system public.

best,
Johan Brichau
