Welcome to the Reflectivity!
The Reflectivity is work on progress based on Squeak. It provides extensions to the standard reflection features of Smalltalk for both structural and behavioral reflection: - Structural reflection is extended by sub-method reflection: the structure of method bodies has as a first class and causally connected representation that can easily be extended and annotated.
- Behavioral Reflection is provided by a new and improved version of Geppetto, a realization of Partial Behavioral Reflection as pioneered by Reflex.
There are some slides from a demo at DYLA07 here
- Persephone. This provides Reflective Methods and a small "JIT" compiler (extensible with plugins) to generate bytecode for execution.
- Geppetto. Reflex for Squeak, redone. Simplified a lot from the original Geppetto, it uses annotations on method structure instead of bytecode manipulation.
Latest Release: 0.19, Ready to run image: Reflectivity.zip
