*load-pathname* and *compile-file-pathname* issues
by Marco Antoniotti 16 Dec '25

16 Dec '25

Hi I am getting old and I get confused. Here is the thing (a followup to the "wild" ASDF module question). I am writing something that will have, at run time, a variable * the-directory-where-stuff-is*. Now, I want to initialize this variable automagically, with no "outside" references. I thought I could do something like (defvar the-directory-where-stuff-is* (merge-pathnames (make-pathname :directory '(:relative "stuff") :name nil :type nil) (make-pathname :name nil :type nil :defaults *load-pathname*))) Alas, ASDF and other things may move the compiled file to a cache folder, which, in the end misaligns *load-pathname* w.r.t. where "stuff" actually is (and should be). This is something that build systems like cmake achieve with the notion of "source", "install", etc folders. Any ideas, suggestions, incantations, workarounds, even at the ASDF level to get this done? Thanks -- Marco Antoniotti

Loading the content of a "data" directory with ASDF (vel similia)
by Marco Antoniotti 01 Dec '25

01 Dec '25

Hello parenthetically unchallenged friends! Suppose I have a library that is structured as src/ code.lisp pkg.lisp stuff.lisp data/ data-file-1.lisp data-file-2.lisp data-file-3.lisp ... data-file-3-point-14-godzillion.lisp Actually, the data folder could be anywhere. How do I tell ASDF (or similar) to just slurp in all the data files at once? I know it's doable, but maybe someone knows of a better way. Thanks Marco -- Marco Antoniotti, Professor, Director tel. +39 - 02 64 48 79 01 DISCo, University of Milan-Bicocca U14 2043 http://dcb.disco.unimib.it Viale Sarca 336 I-20126 Milan (MI) ITALY REGAINS: https://regains.disco.unimib.it/

Current Lisp job market
by pc＠p-cos.net 19 Nov '25

19 Nov '25

Hi, It has been a while since there was some activity on this mailing list. I am currently looking for a job, and am wondering what the current job market looks like for Lisp, especially Common Lisp (of course ;). Are there still possibilities for finding employment? Cheers, Pascal

Unicode character naming
by Marco Antoniotti 15 Oct '24

15 Oct '24

Hello parenthetical crowd Is there a consensus about how to "name" Unicode characters, or every implementation does whatever it likes (thus breaking otherwise perfectly portable code)? Cf., #\INFINITY All the best MA PS Do not even think to use the "hey, it is an implementation-dependent thing" argument! -- Marco Antoniotti, Professor tel. +39 - 02 64 48 79 01 DISCo, University of Milan-Bicocca U14 2043 http://dcb.disco.unimib.it Viale Sarca 336 I-20126 Milan (MI) ITALY

CDR for Package-Local Nicknames [Feedback Request]
by Alexander Fedorov 13 Jul '24

13 Jul '24

Dear all, Over 10 years ago, SBCL implemented the Package-Local Nicknames (PLNs) extension. Since then, PLNs have also been adopted by multiple implementations (ABCL, CCL, ECL, Clasp, Allegro CL and LispWorks) and are now widely used in many projects. However, PLNs are still considered experimental, as stated in the SBCL manual, since there is no formal specification for them, and each implementation interprets various corner cases differently. While the need for a specification has been previously discussed, I was unable to find any publicly accessible draft for one. Therefore, I have drafted a specification intended to become a CDR document. I initially wrote this draft about a year ago and have recently revised it. You can find the latest version here: https://gleefre.github.io/cdr-package-local-nicknames/index.html. There are currently nine unresolved standardization issues, each with at least one proposed resolution. Input on those issues would be particularly helpful, but any feedback is welcome! P.S. I am sharing this link across multiple platforms to reach as many lispers as possible. This includes various mailing lists (Lisp Pro, CDR-discuss and -devel for various CL implementations); IRC channels (#commonlisp and implementation-specific ones); the Lisp Discord server; several Telegram groups; and a post on Reddit. If you have any suggestions for additional places to share the link, please let me know. My apologies to those receiving this message multiple times. Best regards, Alexander Fedorov.

Seeking early adopters for a CL product
by John Morrison 28 Jun '24

28 Jun '24

Hi All; Can't think of a better place to find people to help us refine a fledgling CL product than this list. We are seeking early adopters for our distributed situational awareness platform, key bits of which are written in Common Lisp. It's a "local first" (completely self-hosted) slippy-map, plus: a 3D globe, a data fabric, an OpenStreetmap PostGIS database, a nominatim geocoder, etc. Here <https://drive.google.com/file/d/1bI7RyHD0pgkXdCDxk6Z4RoRwUB9QiFyv/view?usp=…> is the two-pager. Please send any replies not to the list, but to me directly. Thanks in advance, John Morrison (who actually used a wire-wrapped CADR back in the day, and owns a MacIvory whose Mac II host motherboard probably needs to be recapped) --- John Morrison <jm(a)symbolic-simulation.com> Chief Technology Officer Symbolic Simulation, LLC <https://www.symbolic-simulation.com> m: (617) 388-3071 <+1-617-388-3071> <https://www.symbolic-simulation.com> *CONFIDENTIALITY NOTICE: The information transmitted by this email is intended only for the person or entity to which it is addressed.
