(I'm not > familiar with cltl2, I'm affraid) Hi, Yes by environment I mean the &environment parameter to defmacro. The distributed version of lparallel uses variable-information to create closures which are executed on remote machines. Since at least four implementations offer variable-information (SBCL, CCL, LispWorks, Allegro), this technique amounts to a somewhat portable way to serialize closures.

[armedbear-devel] variable-information?
by James M. Lawrence 02 Mar '13

02 Mar '13

Is there something akin to variable-information in CLTL2? For a given environment I would like to know if a symbol is a lexical variable or a symbol macrolet.

[armedbear-devel] Package-local nicknames landed
by Rudolf Schlatte 01 Mar '13

01 Mar '13

Hi, I just committed support for package-local nicknames in abcl. This follows the lead of sbcl and lets you introduce short, meaningful nicknames ("XML" for "COM.WHATEVER.FOO.XML-PARSER") in your own packages without fear of package (nick)name collisions. Here's the example from Nikodemus' documentation: (defpackage :bar (:intern "X")) (defpackage :foo (:intern "X")) (defpackage :quux (:use :cl) (:local-nicknames (:bar :foo) (:foo :bar))) (find-symbol "X" :foo) ; => FOO::X (find-symbol "X" :bar) ; => BAR::X (let ((*package* (find-package :quux))) (find-symbol "X" :foo)) ; => BAR::X (let ((*package* (find-package :quux))) (find-symbol "X" :bar)) ; => FOO::X This puts :package-local-nicknames on *features*; I had to increase the fasl version since %defpackage got a new parameter. Cheers, Rudi

[armedbear-devel] strange interaction between ql:quickload and ABCL
by Anton Vodonosov 28 Feb '13

28 Feb '13

Hello. I have very strange behaviour of ql:quickload that I observer only on ABCL. It happens when I run (ql:quickload :modf). Precondition: the system :modf is NOT installed into quicklisp. > java -jar abcl.jar --noinit --nosystem Armed Bear Common Lisp 1.1.0 Java 1.6.0_26 Sun Microsystems Inc. Java HotSpot(TM) 64-Bit Server VM Low-level initialization completed in 0.945 seconds. Startup completed in 4.8 seconds. Type ":help" for a list of available commands. CL-USER(1): (load "C:\\Users\\anton\\quicklisp\\setup.lisp") T CL-USER(2): (ql:quickload :modf) Error loading C:/Users/anton/quicklisp/dists/quicklisp/software/closer-mop-20130128-darcs/closer-mop.asd at line 43 (offset 1649) #<THREAD "interpreter" {40773F4B}>: Debugger invoked on condition of type LOAD-SYSTEM-DEFINITION-ERROR Error while trying to load definition for system closer-mop from pathname C:/Users/anton/quicklisp/dists/quicklisp/software/closer-mop-20130128 -darcs/closer-mop.asd: Unrecognized keyword argument ("closer-mop-packages" "closer-mop-shared") Restarts: 0: REINITIALIZE-SOURCE-REGISTRY-AND-RETRY Retry finding system closer-mop after reinitializing the source-registry. 1: ABORT Give up on "modf" 2: TOP-LEVEL Return to top level. [1] ASDF0(3): As you see it is trying to load closer-mop. Why? If :modf ASDF is not available, quicklisp should not load anything other systems yet. Moreover, modf.asd has :depends-on (:alexandria #-abcl :closer-mop :iterate) So on ABCL it does not depend on closer-mop. I got backtrace using this command: [1] ASDF0(3): (with-open-file (stream "C:\\Users\\anton\\unpacked\\abcl\\abcl-bin-1.1.0\\backtrace.txt" :direction :output :if-exists :supersede :if-does-not-exist :create) (let ((*debug-io* stream)) (top-level::backtrace-command "10000"))) The resulting file is here: https://dl.dropbox.com/u/5708042/backtrace.txt. @abcl dvelopers: this backtrace seem to contain not only the current invocation stack, but also previous calls, already finished. For example the (LOAD "C:\\Users\\anton\\quicklisp\\setup.lisp") at the very bottom of the file. Do I retrieve backtrace incorrectly? Back to the ql:quickload problem. I know that if I install :modf with CCL, this problem doesn't happen anymore, and ABCL can load it. Zach, how it works? Best regards, - Anton

[armedbear-devel] encoding issues with ABCL
by Faré 26 Feb '13

26 Feb '13

Dear ABCL developers, it looks like ABCL is not doing the Right Thing with respect to LOAD's :EXTERNAL-FORMAT argument, instead reading everything with some dubious default from the environment. Can you fix it? For instance, in Robert Golman's test below, the file is read as MacRoman. Please check COMPILE-FILE too in case it has the same bug. —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org Men have a much better time of it than women; for one thing they marry later; for another thing they die earlier. — H.L.

[armedbear-devel] How can I build ABCL 1.1.1 without recording the absolute path of the source ?
by Xiaofeng Yang 23 Feb '13

23 Feb '13

Hi, all I built ABCL 1.1.1 using Ant. After I built it, I found that the source locations of all the symbols are absolute path. For exmaple: [1] CL-USER(1): (symbol-plist 'defun) (SYSTEM::%SOURCE (#P"L:/abcl-src-1.1.1/src/org/armedbear/lisp/precompiler.lisp" . 44441) PRECOMPILER::PRECOMPILE-HANDLER PRECOMPILER::PRECOMPILE-DEFUN) I tried using '--nosystem', setting (LOGICAL-PATHNAME-TRANSLATIONS "sys") by myself, and even deleting system.lisp from the jar. But the source location didn't change. How can I build ABCL 1.1.1 without recording the absolute path of the source ? Or, making the source location changable so that I can locate it even if I change the path of the source code ? I think I can do it manually by i.g. (dolist (pkg (list-all-packages)) (do-symbols (sym pkg) if there exists system::%source in symbol-plist, replace it)). Is there any other way to do this ? Thanks Best regards, Xiaofeng Yang

Congratulations! You've met the autoloader, now level up... In order to reduce initial system boot times (and also to partially optimize for booting over the network), not all functions corresponding to symbols in the base ABCL system are loaded initially. Instead, the symbol function slot contains a stub which when first executed as a function loads the necessary code, which as a side effect also populates the symbol plist. Users of the implementation may currently interact with this mechanism meaningfullly through the EXT:AUTOLOADP and EXT:RESOLVE functions, which tell you if a symbol needs to be autoloaded and to resolve it, respectively. Using these functions we may define (defun maybe-resolve-symbol-plist (symbol) (when (autoloadp symbol) (resolve symbol)) (symbol-plist symbol)) which you can then use in your code to change the source locations. yers, Mark -- A: Because it messes up the order in which people normally read text.

[armedbear-devel] ASDF 2.30 released
by Faré 21 Feb '13

21 Feb '13

Dear Lisp hackers, ASDF 2.30 is another stability release in preparation for ASDF 3. Since 2.29, in addition to specific portability fixes for CCL and CMUCL, it notably restores some backward compatible behavior for syntax tables around loading .asd files, using mutable global tables, instead of standard syntax tables. Just like 2.29, 2.28 and 2.27 before it, ASDF 2.30 is a pre-release of ASDF 3, an almost complete rewrite of ASDF, and includes a vast number of improvements since ASDF 2.26. http://lists.common-lisp.net/pipermail/asdf-announce/2013-February/000014.h… We invite all implementation vendors to update to ASDF 2.30. We also invite all implementations to make the standard *readtable* and *print-pprint-dispatch* tables immutable, with useful error messages when a modification is attempted. See how the CLHS forbids conformant programs from modifying them: http://clhs.lisp.se/Body/26_glo_s.htm#standard_readtable http://clhs.lisp.se/Body/26_glo_s.htm#standard_pprint_dispatch_table Such modification can only result in problems down the line for users, and it would be nice if at least when SAFETY isn't 0, that were checked. In some unspecified future, we'd like to revert to ASDF 2.29's behavior of binding the syntax tables to their standard values, and then we hope that most implementations will immediately catch misguided attempts by users to modify them (SBCL is the only implementation enforced immutability on both tables). Many thanks to stassats and avodonosov for their help in testing ASDF and helping make it more robust, more portable and more backward compatible. —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org In a free market there are no market failures, only market opportunities.
