Fwd: ASDF walkthrough
by Faré 04 Jan '14

04 Jan '14

Dear Lisp hackers, I'm considering recording a walk through the ASDF sources. I'd like to have an interactive session over Google Hangout with one or a few people, explaining the current code in asdf/defsystem (i.e. not going into uiop, except to minimally explain what asdf uses). That should take about 2 hours. To enjoy the walkthrough, you need to be somewhat fluent in Common Lisp, and somewhat familiar with how to use ASDF, though not necessarily with either extending it or hacking its internals. If at least one person is familiar with ASDF 2 and has questions, that could be interesting, or that could be a separate session. Please respond me to this email (privately or publicly) if you're interested. —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org If a trainstation is where the trains stop, what is then a workstation... — Lars Lundgren <d95lars(a)dtek.chalmers.se>

Enumerated Types in CL.
by Antoniotti Marco 03 Jan '14

03 Jan '14

Hello I created a small library to define “enums” in Common Lisp. It is Yet Another^n DEFENUM macro. The site is defenum.sourceforge.net. A blog entry with some comments (especially by Farè) is here: http://within-parens.blogspot.gr/2014/01/enumerated-types-in-cl.html I would not mind having a discussion about the beast. The design is simply “let’s do in CL what they do in Java and C/C++”, so it does have some shortcomings and the implementation is still sub-optimal. All the best -- Marco Antoniotti

ELS'14 - 7th European Lisp Symposium IRCAM, Paris, France May 5-6, 2014 http://www.european-lisp-symposium.org/ The purpose of the European Lisp Symposium is to provide a forum for the discussion and dissemination of all aspects of design, implementation and application of any of the Lisp and Lisp-inspired dialects, including Common Lisp, Scheme, Emacs Lisp, AutoLisp, ISLISP, Dylan, Clojure, ACL2, ECMAScript, Racket, SKILL, Hop and so on. We encourage everyone interested in Lisp to participate. The 7th 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 Please note that IRCAM, the conference venue, is a French institute for research on music and acoustics. Submissions relating Lisp to music or other acoustical matters will hence be particularly welcome, although given no heightened favor during the review process. We invite submissions in the following forms: Papers: Technical papers of up to 8 pages that describe original results or explain known ideas in new and elegant ways. Demonstrations: Abstracts of up to 2 pages for demonstrations of tools, libraries, and applications. Tutorials: Abstracts of up to 4 pages for in-depth presentations about topics of special interest for at least 90 minutes and up to 180 minutes.

:DBG
by Faré 21 Nov '13

21 Nov '13

In ASDF 3.1.0.14, I introduced a macro :DBG (in uiop/utility.lisp). Yes, it's in the keyword package. Why? Because it's the one and only macro I want to be accessible from everywhere without a prefix, yet without modifying existing defpackage forms to make it accessible — because it's only used temporarily for debugging. :DBG is a macro for print-debugging. The syntax is (:DBG tag forms... last-form) The semantics is that if tag is true, print the tag, then for each form, write its source and its values; return the values of the last form. If tag is false, just evaluate the last form and return its values. (Tag is typically a constant keyword or string, identifying the point where values are printed.) The expansion is rather space and time efficient, as far as the semantics permit. I find :DBG soooo useful for print-debugging. I've seen tens of variants of it, but every time with something not quite right in the syntax, semantics or implementation. I just wanted one variant that got everything right, and make it ubiquitous. Because when you need it, you need it now, and there's no time to modify things to load an additional library. And when you're done, you want minimal cleanup, too: just delete the form, except maybe keep the last subform. Previously, I was using (uiop:uiop-debug) from uiop/utility which allows you to load a magic file of your choice that defines a debug mode. The default one I provided was mine, which define :DBG as DBG in your current package (thereby avoiding symbol import issues). But that still adds a new definition everytime and an extra line or form to cleanup. I was recently convinced that using the keyword package instead makes perfect sense: on the one hand, that's using a shared namespace that it is polite to not pollute, but on the other hand, such a temporary print-debugging macro the only use case I imagine of otherwise wanting something to be immediately accessible without package prefixing yet without modifying the package definition form. It's still time to remove that macro before the next release, but I believe it's the right thing to include it, and maybe some of you will agree with me and start using it, if not from the yet unrelease ASDF 3.1.1, perhaps from a copy in your .sbclrc. —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org The common argument that crime is caused by poverty is a kind of slander on the poor. — H.

Closer projects moved to sourceforge
by Pascal Costanza 08 Nov '13

08 Nov '13

Hi, I have moved the hosting of the Closer projects (MOP Feature Tests, Closer to MOP, ContextL, Filtered Functions, AspectL, LW Compat) to sourceforge. I also switched from darcs hosting to git hosting. You can find the software now at http://sourceforge.net/p/closer/_list/git All libraries have received new version numbers based on semantic versioning. The mailing lists will from now on also be hosted at sourceforge. Please subscribe to the mailing lists at http://sourceforge.net/p/closer/mailman/ if you are interested. The information on the Closer webpage at http://common-lisp.net/project/closer/ has also been updated accordingly. Please let me know if you have any questions or problems.

Looking for CDR volunteers
by Pascal Costanza 06 Nov '13

06 Nov '13

I wish to resign from my activities as the main maintainer of the Common Lisp Document Repository (CDR - http://cdr.europlisp.org) Although Arthur Lemmens, Edi Weitz, and Marc Battyani have supported the effort throughout CDR's existence, for which I'm very grateful, the main work rested on my shoulders. CDR had some noticeable impact in the seven years of its existence, but it may benefit from some new ideas and a fresh perspective. Since Arthur, Edi, and/or Marc do not want to take over the day-to-day activities for maintaining CDR, this effectively means that we are looking for volunteers to take over its maintenance. I would like to ensure that CDR doesn't become unmaintained, so I will keep on running things for as long as necessary. Feel free to ask any questions, either publicly, or privately to me directly, or via editors(a)cdr.eurolisp.org. Thanks, Pascal -- Pascal Costanza The views expressed in this email are my own, and not those of my employer.
