[Sorry if this isn't quite the usual business for this list.] I've been wanting to get in touch with my old X3J13 colleague JonL White, but email to his last known good address got no response. He is one of the important contributors to Lisp development over the past half century. I believe he is still somewhere in the silicon valley area, but he has had health issues the past several years. Anyone have recent news or contact information? TIA--

[pro] Langutils

From Re: [pro] CL-PDF in ACL 64bit - anyone know how to get 64bit ZLIB? At 5:27 AM +0100 14/8/22, Nick Levine wrote: There should be no "try to build" with quicklisp - it's supposed to Just Work. Not only does Langutils not work (although it can seem to load OK in some contexts), but it can be tricky to unpick such as langutils-tokenize::tokenize-stream with its many layers of macro and readtable optimizations. It doesn't seem so obvious as to where to find who might have unpicked this already. Or find documentation behind a system and its design intent. I.e. although perhaps nothing should be in Quicklisp unless pure and solid, it can be quite a goose chase to try to hunt down remedies when that does not seem the case.

[pro] CL-PDF in ACL 64bit - anyone know how to get 64bit ZLIB?

CL-PDF looks very useful for me. Thanks Marc and the team at ILC2014 for this and all the great info! Ok, now to use CL-PDF on Allegro I SVN'ed it from https://github.com/mbattyani/cl-pdf and tried to build it with acl-load the essence of which is (defparameter *cl-pdf-home* excl:*source-pathname*) (defun cl-file (x) (tpl:do-command "cl" (namestring (merge-pathnames x *cl-pdf-home*)))) (eval-when (load) (mapc #'cl-file '("defpackage" "cl-zlib-small" "pdf" "pdf-base" "pdf-geom" ))) note the lower case do-command "cl" not "CL" since I am in modern mode ACL 9.0 64 bit Anyhow it does not work, since cl-zlib-small.lisp tells me to: (defvar *libgz-path* "/usr/lib/libz.so" "Set this variable to point to the location of the zlib library (libz.so or zlib.dll) on your system.") which begs the question of where is zlib.dll for 64 bits? It is not on my machine and I cant seem to find it on the WWW... Any LISPer's using CL-PDF on ACL WIndows 64bit who have solved this problem? Any help much appreciated... Martin M

[pro] AMOP question: When and where is slot-value-using-class called?
by Jean-Claude Beaudoin 04 Aug '14

04 Aug '14

Hello CL Pros, Lately I have been trying to understand the inner workings of the MOP slot protocol as I go through yet one more reading of the usual CLOS litterature (CLHS, AMOP, OOP The CLOS Perspective). To that end I put together a little test file (here attached) and ran its code in sbcl, clisp, ccl, acl and lispworks. I got different results in pretty much each CL implementation on the tracing of calls to slot-value-using-class. I am puzzled and baffled. The results I see go like this: sbcl: only accessors (foo-a) call s-v-u-c. clisp: both accessors and cl:slot-value call s-v-u-c. ccl: s-v-u-c is called neither by cl:slot-value nor by accessors. acl: both accessors and cl:slot-value call s-v-u-c. lispworks: only cl:slot-value calls s-v-u-c. Only clisp and acl seem to agree. And the cherry on the cake's icing comes with sbcl when then defmethod on s-v-u-c is moved ahead of the defclass/make-instance sequence. Then, in sbcl, both accessors and cl::slot-value call s-v-u-c as in clisp and acl. So my question is: Which one is right? Thank you for your help. Jean-Claude Beaudoin
