I uploaded a new release of Clasp today (January 25th, 2015) that brings a lot of stability improvements, improved performance, improved compatibility with the Common Lisp standard and ASDF, SLIME and Quicklisp support.
It requires a reinstallation of externals-clasp. We are working on eliminating the need for externals-clasp.
- ASDF support has been added – it can be accessed using (require :asdf)
- SLIME support has been added and the changes to SLIME have been uploaded to the standard SLIME repository. You should be able to access it the standard way you install and upgrade slime.
- Quicklisp support has been added. I’ve submitted the changes to quicklisp to Zach Bean (the developer of quicklisp) and they should be available soon.
- Improvements in performance of the compiled code (Linux code is at least 2x faster).
- Improvements in stability.
- Almost all Common Lisp symbols have been implemented (18 left, you can see them using (core:calculate-missing-common-lisp-symbols).
- Example code for Clasp/C++ interoperation is available.
- Weak-key-hash-tables, weak-pointer, weak-key-mapping types have been implemented in both garbage collectors.
This release focused on getting SLIME working because I want to incorporate a new compiler front end for Clasp and I want to do it in this extremely powerful programming environment.
