The FAMIX-Lisp meta-model is an extension of the FAMIX meta-model. The FAMIX-Lisp meta-model extends the FAMIX meta-model with capabilities to model Lisp systems by adding some new entities, like Macros and CLOS entities.
CL-Famix is not a toy implementation; it was successfully applied for extracting models from an important number of real-world systems ranging in size from 5KLOC to large-scale systems of 350KLOC.
The Lisp models extracted with cl-famix can be imported and analyzed with the MoosLi plugin for the Moose re-engineering environment.
