MartinDias / Ficus

This repository contains a family of experiments:

Ficus provides a framework for defining tree-like immutable objects. It support first-class edits, which represent operations that can be applied to Ficus objects. It also supports first-class changes, which represent the change after applying an edit to a Ficus object.
FicusMetamodel defines a Ficus model (i.e. tree-like immutable objects) to represent Pharo metalevel objects.
RingFicus defines wrappers for FicusMetamodel which are polymorphic to real Pharo metalevel objects. In a nutshell, it's like the original Ring but with more isolation and more lightweight.

Also check Yrupe project, a serializer for Ficus objects.
