#chez — Public Fediverse posts

Cautiously excited. This is the #racket programming language on #haikuos - specifically it's the DrRacket IDE running on Haiku.

This was a goal for me when I started porting #Chez #Scheme to Haiku this year (Racket is built with Chez). Prof. Matthew Flatt did some initial work in a Racket branch when he reviewed my work on Chez, and today I took that branch and made a handful of changes, and very rapidly got here (I'm flabberghasted that all the Raco buildout worked and gracket too)

It's a small thing, and a small contribution. I've been contributing to Free and Open Source Software for 30 years, and still seeing something I did go out into the world makes me very happy. #chez #scheme 10.4.0 is out now on #haikuos

@mason also, I’ll have to update the #haikuports version of #chez #scheme this weekend too, the patches I used to make it run on #haikuos have been adopted upstream and now released. Thus we can simplify that port!

Nothing too exciting, unless you're me - for the first time I have #chez #scheme placing a graphical window on my #haikuos desktop - this is using the native C++ API, wrapped as a C API and then accessed via FFI.

And, with the kind support and assistance of Matthew Flat, the #haikuos port of #chez #scheme has landed in the main branch of the repository! That should allow a simplification of the #haikuports package in the future too!

Phase 2 took a step forward. Someone else fixed a threading issue and that made everything pass on the HEAD of the git repository for #Chez #scheme on my #haikuos build box. So I've just submitted the PR to the upstream project to re-establish Haiku support in Chez. Let's see how that goes.

Reminder, the #haikuports version of Chez Scheme is already available.

I've done a bit of experimenting getting #racket to build, but I'm not there yet. #Akku looks promising too.

Next steps:
- Work on getting the new machine types into the upstream #Chez #Scheme project.
- Take this work and use it to get #Racket building on top of Chez for #HaikuOS

The #chez #scheme port got merged in the #haikuports repository just under an hour ago.

Yay. Happy hacking #haikuos users who love Scheme (there must be at least four of us!).

The #chez #scheme port for haiku is progressing through review. I was impressed with the speed and quality of reviewing that was done so far. As a first time contributor to #haikuports it's really nice to get the feedback and tips. #haikuos #scheme

Well, I had to learn more that I was expecting (particularly about how tests work in the #chez #scheme code), but I've just submitted the PR on the #haikuports
repository. If that port gets accepted I'll have a go at getting the new #haiku machine types for Chez added to the upstream project.

I might then move towards getting #racket up and running on #Haiku on the basis of the Chez port. #haikuos

A little update on my efforts to port #chez #scheme to #Haikuos . I'm pretty sure (as per my last post) that its running fine, but there are certain aspects of Haiku that need to be properly reflected in the test suite.

Chief among these areas is the filesystem - some file operations that the test suite expects to fail, which simply succeed. Some of this is because Haiku, as a single-user OS, basically gives you root rights across the whole filesystem.

interesting Cadence Research Systems-oriented Cisco patent featuring Andy Keep as an inventor:

"Theres a system compiler comprising: block 1 compiler to compile logic for a logical block in a first language, the 1st language being a DSL & the 1st logic block being switching logic for a network switch; a 2nd block compiler to compile logic for a 2nd logical block in another DSL, the 2nd language being a non-DSL..."

I updated my "is #guile fast?" page with the new r7rs #benchmarks data and anchored Guile and #Chez in the benchmarksgame:

#Scheme benchmarks: https://www.draketo.de/software/guile-fast#other-schemes
Compared to other languages: https://www.draketo.de/software/guile-fast#other-languages

Chez is roughly factor 7 slower than C,
Guile roughly factor 18

@mdhughes here is the thread system of #Chez. Its a simple pthread interface. Deadlock land. #Racket has offered basic /unsafe pthread primitives since version 6 I think

This may be what finally pushes me over the edge to become a normal person by finally ditching #Chez #Scheme for Racket:
"With the version 9.0 release, #Racket includes support for shared-memory threads that can take advantage of multicore hardware and OS threads to run in parallel— not merely concurrently with other Racket threads, as was the case in versions before 9.0."

Spending ten hours troubleshooting Podman - NextCloud only to fibnally realize I had a symbol in the password that podman couldn't handle ..... AAAAaaargh! #self-hosted #nextcloud #podman #linux #chez-geek

Prof. Dybvig's paper, "The Development of Chez Scheme" (2006), is a brief history of the #Chez Scheme compiler that he had been working on since 1985. Despite his quiet, understated tone, he manages to convey in this paper his heart-felt enthusiasm for, and decades-long dedication to, the Scheme language and its implementations. This is indeed an inspiration to all of us #geeks. Today, Chez Scheme is one of the fastest, most compact, and most advanced implementation of #R6RS.

Dybvig was, in turn, a student of another pillar of the Scheme community, Prof. Friedman. I first came across Dybvig's work, when I read the 1ed of his famous book, "The Scheme Programming Language" (1987), the 4ed of which was published in 2009 and it covers R6RS.

https://www.amazon.com/Scheme-Programming-Language-Kent-Dybvig/dp/013791864X

The book "Chez Scheme Version 10.0.0 User’s Guide" (2024), published by Cisco, covers the inner workings of Chez Scheme v10, which is a superset of R6RS.

Chez Scheme and the whole of Dybvig's work are the guide posts for all #Lisp and #Scheme #programmers.

shoutsing out to this talk: https://www.youtube.com/watch?v=BcC3KScZ-yA

it covers a lot of fascinating dynamic language compiler techniques in a really digestible way. 11/10

also, and i somehow didn't realize this was the same guy, there's this one: https://www.youtube.com/watch?v=Os7FE3J-U5Q

this one is more about the nanopass framework, which is extremely cool. i think i prefer the first talk because it's more packed with 1337 tr1ckz learned from his time working on chez scheme, my beloved

I remember hearing that #Racket made some progress towards migrating to upstream #Chez, does anybody know what the status of that is? Racket users and users of software written in Racket would benefit immensely from this.

Chez is a powerful infrastructure in a ~500kb statically linked binary that approaches C in performance. Due to its low-level and bare bones compilation and build tools, you can also compile in only what you need. racket-minimal on #guix is ~160mb, which is great for what you get, but still 320x the size of Chez. Having Racket's ecosystem while being able to ship only chez + the compiled chez code of the libraries you import could allow for shipping sophisticate programs in only a few mb. Just saying.

Changes from Racket fork of Chez Scheme are getting merged back to Chez.

@vruz @zardoz03

totally, minimalism at the language level enables innovation at the compiler level, and thus a rock solid infrastructure that does "one thing and does it well" ((cross)compiles a sufficiently expressive imperative language to lean fast static binaries). but if thats the reason to its success, then why isn't #chez just as successful? the obvious answer is that #go is backed by google, but so is #dart, which is successful soley due to flutter, and doesn't seem to really be adored anywhere, so it seems unsuccessful at the fandom level.

because like, what the hell is even going on there. it's a feature pile that most of its users seem to find annoying (including me, as I'm currently using it at work), but it has a powerful compiler infrastructure with native rendering capabilities that you can't find anywhere else. for this reason, I imagine projects targetting dart like #ClojureDart will start to take off, and dart will increasingly be a platform to target, similar to other successful JVM languages like clj & #kotlin (which is Google's official "first order" recommendation for Android dev today).

so I do think that go's success, as a language that its community really loves using, isnt just the solid infrastucture. I think its that it holistically captures a refined vision of the #unix philosophy that has includes insight from the longue duree of the innovations of plan9
