Which pattern matcher should I use for chez scheme ?
https://srfi.schemers.org/srfi-241/srfi-241.html
It seems like there is different versions of similar concept.
https://github.com/scheme-requests-for-implementation/srfi-241
https://github.com/ArnautDaniel/thunderchez/blob/trunk/match.ss
https://github.com/scheme-libraries/scheme-libraries/blob/main/lib/scheme-libraries/define-match.sls
I am currently trying to get the latter working. I have put the code in my chez scheme load path, and it at least succesfully imports:
> (import (scheme-libraries match))
> ;; no errors
https://codeberg.org/pkw/chez-start
This is my notes for setting up a consistant/repeatable chez scheme environment.
It's basically a Makefile that will install chez and chez-ncurses (To show installing an extra lib).
Then the Makefile can run code using chez from the commandline or repl.
(To prove it's working.)
Damn, Chez Scheme called my bluff:
(let ((x (apply values (iota 12349033)))) (+ x 1))
Exception: returned twelve million three hundred forty-nine thousand thirty-three values to single value return context.
I did not expect them to have a full number to string function for the error messages. I stand corrected.
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.
https://cisco.github.io/ChezScheme/csug10.0/csug.pdf
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
There are a few cool commits landed on guix master today:
- chez-scheme: Update to 10.0.0.
- racket: Update to 8.12.
- chez-scheme: Bootstrap from source.
- Add librewolf.
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.
🌖 即將合併以創建 Chez Scheme v9.9.9
➤ Chez Scheme 的主要分支即將與 racket/ChezScheme 分支合併，版本將為 v9.9.9-pre-release.20
✤ https://groups.google.com/g/chez-scheme/c/D7g6mIcYLNU
Chez Scheme 的主要分支將與 racket/ChezScheme 分支進行合併，合併後的版本將為 v9.9.9-pre-release.20，這是向 v10.0 發布的一個步驟。合併後，cisco/ChezScheme 的內容將與 racket/ChezScheme 的功能幾乎相同，並且保證了變更不會影響 Chez Scheme 的一致性和品質。
+ 這是一個重要的合併，對於 Chez Scheme 的發展來說非常有意義。
+ 很期待看到合併後的版本，希望能帶來更多的功能和改進。
