(gitlab is uusable; i have to report here.) ecl 21.2.1 gives: > (log 1/6319748715279270675921934218987893281199411530039296) Debugger received error of type: DIVISION-BY-ZERO #<a DIVISION-BY-ZERO 0x7ff5afe6c540> Error flushed. whereas other cl's (i testyed sbcl and ccl) give results like: ? (log 1/6319748715279270675921934218987893281199411530039296) -119.27552 I tested on amd64 (gentoo) and arm64 (debian and netbsd) with identical results. i did not have a musl box or other bsd to test on. run with --no-trap-fpe, the result is #<single-float negative infinity>. another example is: (truncate (log 1/6319748715279270675921934218987893281199418867)) Debugger received error of type: ARITHMETIC-ERROR #<a ARITHMETIC-ERROR 0xffff8f688a40> whereas this works: (truncate (log 1/631974871527927067592193421898789328119941867)) -103 -0.27893066 which of course suggests that the issue is c's long double's precision. it looks like ecl could use an mpq log function; https://github.com/linas/anant might work. -JimC -- James Cloos <cloos(a)jhcloos.com> OpenPGP: 0x997A9F17ED7DAEA6

ASDF 3.3.6 is released
by Robert Goldman 07 Aug '22

07 Aug '22

Dear Lisp Implementation Developers and Maintainers, Today we release ASDF 3.3.6, the sixth bugfix release for the 3.3 release series, and -- it is devoutly to be hoped -- the final one. We urge implementations that are currently bundling previous versions of ASDF -- and especially those bundling 3.3.0 through 3.3.5 -- to upgrade to 3.3.6 at their earliest convenience. As maintainer, my primary role continues to be coordination and some limited quality control. The real work for this release has been done by many contributors and bug-reporters, to whom the Common Lisp community owes a tremendous vote of thanks. Their names are listed on the Changelog, appended below. An extra special thanks is due to my co-maintainer, Eric Timmons, who has provided many fixes and also has overhauled and much improved our regression testing. We *hope* that the next release will be 3.4, introducing new functionality but which, as the numbering suggests, will be backward compatible. Best, Robert * Fix bug loading ASDF system definitions from jar files on ABCL. See !190 * Fix bug with version numbering after reload. See !194 and #94. Thanks to Eric Timmons. * Fix bug in return value of UPGRADE-ASDF. See !195. Again, thanks to Eric Timmons. * Multiple improvements to documentation and tests. Thanks to Nathan Ringo and Phoebe Goldman. * Add clasp support for uiop/launch program. Thanks to Christian Schafmeister. * Miscellaneous minor bug fixes and tweaks. * Don't let *package* binding leak into ASDF compile operations. Thanks to Phoebe Goldman.

--norc --shell fails
by James Cloos 03 Jul '22

03 Jul '22

with 21.2.1, when running a script which has hash-bang line: #!/usr/bin/ecl --norc --shell i get: Unknown command line option --norc --shell. in general, hash-bang lines can only have an executable and zero or one options. the filename is not added when there are two options. it would be best if there were single-character options for --norc and --shell, so they could be combined into one -option. or, alternatively, --shell might imply --norc and there could be a function in ext: which runs the rc file(s) for those times (if any) when --rc --shell would be preferred. -JimC -- James Cloos <cloos(a)jhcloos.com> OpenPGP: 0x997A9F17ED7DAEA6

[CfPart] ELS 2022, 15th European Lisp Symposium, March 21-22, Porto.

10 Mar '22

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 15th European Lisp Symposium Call for Participation March 21-22, 2022 FEUP, Porto, Portugal & Online In cooperation with ACM SIGPLAN https://www.european-lisp-symposium.org/2022 Sponsored by EPITA, Franz Inc., and SISCOG ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Important News ~~~~~~~~~~~~~~~ - Full programme now online - Invited speakers below - Registrations are open Scope ~~~~~ The European Lisp Symposium is a premier forum for the discussion and dissemination of all aspects of design, implementation and application of any of the Lisp dialects, including Common Lisp, Scheme, Emacs Lisp, Clojure, Racket, ACL2, AutoLisp, ISLISP, Dylan, SKILL, Hy, Shen, Carp, Janet, uLisp, Picolisp, Gamelisp, TXR, and so on. We encourage everyone interested in Lisp to participate. The European Lisp Symposium invites high quality papers about novel research results, insights and lessons learned from practical applications, and educational perspectives. We also encourage submissions about known ideas as long as they are presented in a new setting and/or in a highly elegant way. Topics include but are not limited to: - context-, aspect-, domain-oriented and generative programming - macro-, reflective-, meta- and/or rule-based development approaches - language design and implementation - language integration, inter-operation and deployment - development methodologies, support and environments - educational approaches and perspectives - experience reports and case studies Invited talks ~~~~~~~~~~~~~ Building SICMUtils, the Atelier of Abstractions -- Sam Ritchie SICMUtils is a Clojure library designed for interactive exploration of mathematical physics. It is simultaneously a work of persuasive writing, a collection of essays on functional pearls and computational ideas, a stable of workhorse functional abstractions, and a practical place to work and visualize algorithms and physical systems, on a server or in the browser. How do you build a library like this? This talk will go through the architecture of SICMUtils, based on many of the ideas of "additive programming" from Gerald Sussman and Chris Hanson's latest book, Software Design for Flexibility. We'll look at surprising examples of the system becoming easier to extend over time. Clojure's embrace of its host platform lets us use the best modern work in Javascript for visualization, while keeping the horsepower of our servers for real work. Lisp's particular elegance will shine throughout. Creating a Common Lisp Implementation -- Robert Strandh Being dissatisfied with the way current Common Lisp implementations are written, and with the duplication of system code between different implementations, we started the SICL project in 2008. The initial idea was to create modules that the creators of Common Lisp implementations could use to create a complete system from an initial minimal core. But this idea was unsatisfactory because it required each module to be written in a subset of Common Lisp. So instead, we decided to use the full language to implement these modules, effectively making them useless to an implementation using traditional bootstrapping techniques. We therefore decided to also create a new Common Lisp implementation (also named SICL), that could use those modules. A crucial element is a bootstrapping technique that can handle these modules. In this spirit, we have developed several modules, including an implementation of CLOS which is also an important element of bootstrapping. Lately, we have increased our level of ambition in that we want to extract those modules as separate (and separately maintained) repositories, which requires us to deal with code during bootstrapping that was not specifically written for SICL. In our talk, we describe this evolution of ambition, and its consequences to bootstrapping, in more detail. We also give an overview of several new techniques we created, some of which have been published (at ICL and ELS) and some of which have not. Finally, we discuss the future of the project, and other projects for which we imagine SICL to be a base. Lisp as Renaissance Workshop: A Lispy Tour through Mathematical Physics -- Sam Ritchie Lisp is an exquisite medium for the communication of computational ideas. From our most accurate observations of physical reality up through chemistry, biology, and cognition, the universe seems to be computing itself; modeling and simulating these systems in machines has led to incredible technological wealth. Deep principles and beautiful abstractions seem to drive these systems, but they have always been hard to discover; and we are floundering at the computational frontiers of intelligence, synthetic biology and control systems for our climate. The only way to push forward is to build powerful tools that can communicate and teach. This talk will take a tour through SICMUtils, a Lisp system designed as a workshop for conducting serious work in mathematical physics and sharing those explorations in a deeply interactive, multiplayer way. The library’s growth parallels our human scientific history; hopefully tools like this will help us write the next chapter.

Considering resignation as maintainer
by Robert Goldman 10 Jan '22

10 Jan '22

I have discovered that Stas Bokuraev is continuing to refuse to update Edi packages to modern ASDF system-naming. This would not be bad in and of itself, because these are open source systems, and they can be forked. What *is* bad is that he has publicly stated that he is doing this hoping that the resulting warnings will break people's systems and thus cause them to get angry and complain to me about ASDF checking system names. What is even worse is that the CL community tacitly accepts this as normal behavior. I would like to see the CL open source community pause and consider what constitutes a healthy community. I don't believe that someone trying to break things in order to pressure a volunteer maintainer of infrastructure is something that a healthy community should accept. If the community prefers a more rough-and-tumble approach, I can accept that, but if so it's time for the community to find an ASDF maintainer who is more in harmony with the values it (at least implicitly) espouses.

Re: Re: How to use lisp packages from libraries?
by Иван Трусков 06 Jul '21

06 Jul '21

Thanks for your explanation! I have changed lisp code to have package definition and in-package declaration, and after that everything did work (also, i per your advice used package name in symbol lookup in C code). There is one thing i would like to discuss a little bit further. >The question you need to answer is whether you want your program defer >to run-time, on the user's workstation, when to use quicklisp to > donwload and install the "str" system, and load it into your program > to get the "STR" package and its functions? Do you realize that every > month, new systems are added to quicklisp, but also SOME SYSTEMS are > REMOVED from the quicklisp distribution!? Do you want your program to > break next month because the quicklisp maintainer decided to remove > some depdency from its distribution? 1) packages changing in repository is, well, just the fact of life. In most cases hoping for the best is enough. I mean, there is no certain guarantee that digital infrastructure taken for granted will be there tomorrow? 2) what i am really curious about is: when my lisp package is compiled, let us say, monolithically - is used package "pulled into" it? In resulting object fdile, is there all the machine code corresponding to the functions from it that i have used? Maybe to other ones?
