With pull request #50 the Schemacs Elisp interpreter is now able to load all of two very important Emacs Lisp source files:

./lisp/emacs-lisp/byte-run.el and
./lisp/subr.el

…which are two files that define most of what you could call the the Emacs Lisp “core” language (by which I mean macros like defun and lambda).

With these files now loaded, I can proceed to the next task, which is implementing enough of the C-level built-in functions in Scheme to be able to run ./lisp/emacs-lisp/cl-lib.el, which is in-turn one of the dependencies for running the Emacs Regression Tests (ERT) suite.

Once ERT is up and running, it will be much easier for anyone to contribute code to this project as you will just be able to pick a failing regression test and write whatever code is necessary to make it pass.

wrote a Gauche #Scheme script to query a #mastodon instance blocklist and save it out to an importable file

(define (blocks domain)
(json-link #"https://~|domain|/api/v1/instance/domain_blocks"))

(define (blocklist domain file)
(call-with-output-file file
(lambda (out)
(for-each (lambda (block)
(write-string (cdr (assoc "domain" block)) out)
(newline out))
(vector->list (blocks domain))))))

Hi! I'm new to this instance and to Mastodon in general, I'm here mostly talk to new people about my interests and theirs.

Some of my interests include:
#music #programming, #lisp (and #scheme) and #videogames.

I wrote a followup #article about #lisp 's position in the #programming language #TIOBE rankings top 25 for 2025 including notes from the article's thread.

https://screwlisp.small-web.org/momentary/further-arguments-on-tiobe-lisp/

where I give examples of possibly (not) including historic languages in the list, #scheme viewed as a middle-aged lisp,

speculation about Visual Basic '98 as another completely-stable and reliably supported similarly-to-lisp target,

examples of how the ANSI standardised language still evolves.

Thinking languagey thoughts, and was reminded of #Dylan, the language they wrote for the #AppleNewton but didn't get ready in time & never ended up using.

It's derived from #Scheme and #CommonLisp but it has a built-in object system derived from CLOS, and *looks* a lot like Ruby‡

I really wish they had shipped it. I feel like it died before it ever got a chance to live.

Hey look, I finally did it! Behold #Scheme R^7RS standard in all its glory, now in semantic HTML5! 🥳🥳🥳

I should have posted about Goldfish Scheme to let more people know about it.

当我选择用中文写 Goldfish Scheme 的文学编程文档的时候，我大概没有期望会有很多贡献者来贡献代码。现在已经有12位贡献者了，其实已经大大超出我的期望了。

The presentation is live now, and I am available for questions in the “Big Blue Button” chat room. Feel free to ask me questions here on ActivityPub.

big shoutout to @abcdw who helped improve the dev experience and tests of the project, #hacking on it is now a delight (with #guile #arei #ares on #emacs ).
system is much more modular now, organized, user overrides are easy, and there is a #wip #gruvbox theme support (many more too), added rotating wallpapers

just noticed the new website design for Gauche #Scheme

https://practical-scheme.net/gauche/

Square brackets and curly braces in Common Lisp! :taneŝima_ĝojas:

(set-macro-character #\] (get-macro-character #\)))(set-macro-character #\[ (lambda (stream char) (declare (ignore char)) (read-delimited-list #\] stream t)))

CL-USER> [cadr '{(1 3) 2 3}]1

This makes my heart happy. So happy. Thanks, Paul Graham.

Please let me know in the replies what implementation do you like/use? Or if you use something less common.

I am currently looking for a #job . I am an experienced (senior) software developer/engineer with 7y of experience. If someone is looking for a capable software engineer or knows someone looking for engineers, please let me know.

I do #python #scheme #django #docker and aim for reproducible software. I learned some #devops and #ansible and can manage servers. Used to do #fullstack dev work, before everything needed to be an SPA.

I am looking for #remote work or work in #berlin or #potsdam .
