Google Summer of Code (GSoC) 2011
Below, you'll find a list of projects that we - the ABCL project community - came up with. These projects (or parts thereof) can be completed in a summer and would really help the project leap forward.
After assembling the proposals here, we need to liase with http://lispnyc.org/soc.
Testing framework for DEFINE-METHOD-COMBINATION (D-M-C, the long form)
During the 0.23 development cycle, experimental support for the long form of D-M-C has been added. However, in order to improve the quality of the implementation, tests need to be designed and implemented. If the project leaves time, optionally with fixes to the implementation that we currently have. SBCL's tests may serve as a good basis, but aren't suitable in a copy/paste manner, because their tests aren't RT based, while ABCL's are.
Metaclasses for generic functions
During the development cycle of 0.19, support for the :metaclass DEFCLASS option has been added to ABCL's CLOS. However, DEFCLASS isn't the only CLOS macro which requires support for that option: DEFGENERIC does too.
Difficulty of this project may be that generic functions are based on the FUNCALLABLE-INSTANCE class, for which some investigating may be required to determine if its supports is up to the task of implementing generic functions with non-standard metaclasses.
Make LispObject a Java interface, as God and Gosling intended. Then factor the existing code into a Java5/6 implementation of LispObject. Then, provide an implementation of LispObject that will work on .NET and/or Dalvik.
Port to Dalvik
First get the ABCL interpreter booted on Dalvik. Then, modify our complier to emit Dalvik bytecode.
Improve Java interoperability
Looking at the best ideas from ABCL's JAVA package and Alan Ruttenberg's JSS package while studying the best patterns from Clojure, design and implement an interface possibly using macros, auto-magic PACKAGE import, and other standard language extension features that allow Java developers to easily use ABCL but has solid Common Lisp foundations.
Implement a better debugging facility
ABCL could use a facility to inspect the current Lisp stack frame as well as maintaining better correspondence between compiled and source code. The ultimate goal would be the ability to single step through Lisp programs.
