[pro] Lexer wanted
by Frank Huttner 15 Feb '15

15 Feb '15

buffalo is an LALR(1) parser generator in pure Lisp that performs roughly on par with its large cousin on the "torture" tests from the GNU Bison test suite (https://github.com/fhuttner/buffalo-testsuite) What I find really missing is an equivalent, open-sourced lexer; is there such a project?

[pro] [MOP] Does intern-eql-specializer serve any real purpose?
by Jean-Claude Beaudoin 27 Dec '14

27 Dec '14

Hello CL Pros, Lately I have been improving the MOPishness of MKCL and that brought me in contact with the specification of intern-eql-specializer in AMOP. The EQ requirement on its returned value seem to me to dictate a hash-table implementation (PCL and its derivatives all seem to do just that). The problem I see with this is that it will be a "for ever growing" hash-table with not upper bound in sight. And the "purpose" of such a mandatory built-in memory leak also completely escapes me. Could any of you share some insight on this question, please? Thank you, JCB

[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
by peter 22 Aug '14

22 Aug '14

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?
by Martin Mallinson 22 Aug '14

22 Aug '14

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

[pro] Meaning of "inline" when applied to a generic function?
by Jean-Claude Beaudoin 10 Jul '14

10 Jul '14

Hello CL pros, I am trying to figure out the meaning of the inline declaration when the so qualified function happens to be a generic function. As in: (declaim (inline foo)) (defgeneric foo (a b)) What can be expected of a compiler when it then faces a call to foo while the above is in effect? Is this an obvious no-op or did some find something useful to do in such a context? Thanks for your help, JCB
