From costanza at web.de Tue Jul 27 19:17:26 2004 From: costanza at web.de (Pascal Costanza) Date: Tue, 27 Jul 2004 21:17:26 +0200 Subject: [aspectl-announce] AspectL 0.6 released Message-ID: <9857EB32-E001-11D8-8A94-000A95DB189E@web.de> Hi, I have just released AspectL 0.6 on its website at http://www.common-lisp.net/project/aspectl/ The most notable improvement is that I have successfully ported AspectL to a number of Common Lisp implementations beyond LispWorks. It now runs on the following implementations: - Allegro Common Lisp (with minor restrictions) - CMU CL - LispWorks - OpenMCL (but not special generic functions) - SBCL Apart from some internal changes, porting AspectL to those other platforms has required one important design change. In AspectL 0.5, special generic function had to be defined like this: (defgeneric some-function (some-parameters) (:generic-function-class special-generic-function)) Now, they have to be defined like that: (define-special-function some-function (some-parameters) (:definer some-function*)) You have to provide two names: The first name must be used for calling a special function whereas the second name (the "definer") must be used for defining methods. This avoids some deep problems I have faced when trying to sneak in additional information in the generic function invocation protocol of the CLOS MOP. In all other respects, define-special-function acts like defgeneric. For further details, see the release notes. Pascal -- Tyler: "How's that working out for you?" Jack: "Great."
