Macro system
by Alexandre Rademaker 26 Nov '18

26 Nov '18

In the LoL book we learn the flexibility of the Common Lisp macro system. Reading now http://blog.racket-lang.org/2011/04/writing-syntax-case-macros.html It seems that the Racket macros do not necessarily impose constraints to the programmers. But I never really used it. Does anyone here have experiences with both approaches, sufficient to give insights about the good and bad of each one? Alexandre Rademaker Sent from my iPhone

Common wisdom on arithmetic (IEEE)
by Antoniotti Marco 05 Nov '18

05 Nov '18

Dear all I am fooling around (again!) with the spec of a math library that I want the students to work on as a project. Language is Common Lisp. Essentially the library is an extended generic math library built on the basis of the many ones floating around. Now. Here comes IEEE. And “infinity" Among many implementations there is more or less a consensus about how to “represent” IEEE infinities in CL. E.g. LW > math:long-float-positive-infinity +1D++0 #| +1D++0 is double-float plus-infinity |# CCL ? math:long-float-positive-infinity 1D++0 and so on. NaN is not as clearly defined. LW 45 > math:nan 1D+-0 #| 1D+-0 is double-float not-a-number |# CCL ? math:nan 1D+-0 #| not-a-number |# But to get a NaN in SBCL/CMUCL requires a trick. I use (sb-kernel:make-double-float -524288 0)) ; Courtesy of Raymond Toy. In any case… There are two issues that I would like to brainstorm a bit. The first one pertains rounding modes. Give the current state of affairs, it does not seem possible to access them in all the CL implementations. CMUCL/SBCL give you the necessary hooks, but LW doesn’t. Let’s skip this. The second is just a simple question. Given that we *do* have (with some acrobatics) access to IEEE infinities, would you add symbolic constants to such library like (defconstant +posinf+ ‘+posinf+) or would you just rely on the IEEE infinities? Generic functions like (defgeneric plus (x y) …) Will obviously be affected. I just want to get a feeling about the overall wisdom of this crowd. All the best Marco -- Marco Antoniotti

Common Lisp style: multiple packages in same repo
by Daniel Pezely 28 Aug '18

28 Aug '18

I posted this to Stack Overflow but was hoping for more input. https://stackoverflow.com/questions/51638864/common-lisp-style-multiple-pac… May I get recommendations or links to representative code repositories with good style for multiple related Common Lisp packages, please? For instance, consider a high-level workflow library with accompanying lower-level API, each in its own CL package but same git repo due to synchronized releases. Each system (|*.asd| file) isolates tests and may be invoked using: |(asdf:test-system foo :force t)| Separate systems may be built via |make|, which definitely helps isolate SBCL code-coverage reports. Some users of the library may only want to load the lower-level API. For simplifying dependencies for those using higher-level API, it seems best to keep everything bundled in one repo. Any revision to one library would likely require updating all for the same release. I currently have a single directory tree with a subdirectory for each CL package. There's a top-level |Makefile| plus one in each subdirectory that the library maintain would use. The top-level also contains symbolic links for |.asd| files pointing into relevant subdirectories. (It's a library deeply dependent upon POSIX calls via |uiop-posix|, so it's only applicable on an OS with sym-links.) This seems to be an issue at large considering issue #1 for Quicklisp-docs [0]. Found nothing relevant in Google's CL style guide [1], State of the Common Lisp Ecosystem, 2015 [2], Edi's CL Recipes [3] or Lisp-lang [4]. Browsing repos seem to have quite a mix of styles. * [0] https://github.com/rudolfochrist/quicklisp-docs/issues/1 * [1] https://google.github.io/styleguide/lispguide.xml * [2] https://web.archive.org/web/20160305061250/http://eudoxia.me/article/common… * [3] http://weitz.de/cl-recipes/ * [4] http://lisp-lang.org/learn/writing-libraries but see also their section on Continuous Integration Repo to be fixed: https://gitlab.com/dpezely/cl-mmap (commit a23bd88d of 2018-07-14; release will be tagged when fixed) Thanks, -Daniel

Paredit-mode in the slime repl
by Alexandre Rademaker 07 Aug '18

07 Aug '18

After the last Emacs upgrade to 26.1, the M-s key bind from paredit-mode is replaced by `Next element matching (regexp)` command in the slime repl buffer. Sorry for the silly question, but how to get M-s mapped to paredit-splice-sexp again? In a lisp file buffer it is working as expected. Best, -- Alexandre Rademaker http://arademaker.github.io

emacs lisp mode, mailing list?

Is there a mailing list to ask questions and make suggestions and talk about emacs lisp mode for pro Lispers? Would that be here perhaps?

CDR maintenance
by Pascal Costanza 25 May '18

25 May '18

Hi, The Common Lisp Document Repository (CDR - https://common-lisp.net/project/cdr/) is for all practical purposes currently unmaintained. We have been receiving a few minor requests recently, but don’t have the time anymore to take care of this. Is there somebody else in the community who would like to take over and breathe some new life into this project? Thanks, Pascal -- Pascal Costanza
