Andrew TropinTIL: There is an identifier-syntax macro that you can use to implement syntax-id-rules or do other fancy macro stuff.<a href="https://fosstodon.org/tags/scheme" class="mention hashtag" rel="tag">#scheme</a> <a href="https://fosstodon.org/tags/guile" class="mention hashtag" rel="tag">#guile</a> <a href="https://fosstodon.org/tags/racket" class="mention hashtag" rel="tag">#racket</a> <a href="https://fosstodon.org/tags/macros" class="mention hashtag" rel="tag">#macros</a>

Peter BrettShout-out to @dpk, hero of <a href="https://mastodon.me.uk/tags/Scheme" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Scheme</a> standardisation!I spent an hour wittering about the horrifying hybrid of Lisp and Scheme that we ship in our products, and she did not run screaming…I'm confident that R7RS Large is in safe hands.

Stephen RamsayI'm not sure I can trace how I got there, but something had me playing around with GNU Guile (I've always liked the idea of an embeddable Scheme, I just never got around to looking at it closely).Anyway, Guile is way cooler than I thought -- way more "unix-y" than other Schemes I've known.But the real surprise was a static site generator -- Haunt (<a href="https://dthompson.us/projects/haunt.html" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://dthompson.us/projects/haunt.html</a>) -- and a full-blown web framework -- Artanis (<a href="https://artanis.dev/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://artanis.dev/</a>)!I am so glad both of these things exist.<a href="https://hcommons.social/tags/Scheme" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Scheme</a> <a href="https://hcommons.social/tags/Guile" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Guile</a> <a href="https://hcommons.social/tags/Webdev" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Webdev</a>

Ramin Honary<blockquote>What I don’t like:<ul><li>some stuff breaks “everything is a list” model</li><li>Common Lisp is not minimal, includes overlapping and legacy stuff</li></ul>does <a class="hashtag" href="https://fe.disroot.org/tag/scheme" rel="nofollow noopener noreferrer" target="_blank">#scheme</a> address this?</blockquote><a class="u-url mention" href="https://mastodon.social/@rzeta0" rel="nofollow noopener noreferrer" target="_blank">@rzeta0</a> I would say yes, Scheme sort of addresses those issues.Scheme’s biggest advantage is that it is minimal enough that you can understand the whole language specification top-to-bottom, inside and out. But that is also it’s greatest drawback: is that it is too minimal to be practical. So for a long time, every single Scheme implementation has a it’s own large and unique set of libraries for solving practical programming problems that were incompatible with other Scheme implementations, making the Scheme ecosystem very fragmented. The <a href="https://srfi.schemers.org/%20" rel="nofollow noopener noreferrer" target="_blank">Scheme Request for Implementation (SRFI) process</a> is meant to address this fragmentation issue. Fragmentation is still (in my opinion) a pretty big problem, though things are much better than they were 20 years ago.The R6RS standard, as I understand it, tried to make Scheme more practical, but it started to become too Common Lisp-like in complexity so it was mostly rejected by the Scheme community — with a few notable exceptions, like the <a href="https://www.scheme.com" rel="nofollow noopener noreferrer" target="_blank">Chez Scheme compiler</a>.The next standard, R7RS, split the language into two parts: “R7RS small,” ratified in 2014, which is more like the original minimal core of the Scheme language, but just a few new features, in particular the <code>define-library</code> macro, for modularizing parts of Scheme programs into immutable environment objects. Then they took a collection of “SRFIs” and declared them to be part of the “R7RS large” language standard. The full “large” language specification is not yet fully ratified, even 11 years after the completion of R7RS “small,” but I think the SRFIs they have ratified so far already make the latest Scheme standard a very practical language. The final R7RS standard may end up being larger than Common Lisp, but that is fine with me since it can be almost completely implemented in the R7RS “small” Scheme standard.R7RS “small” Scheme, in my opinion, is a powerful but minimal language that exists to implement other languages, but is still useful in it’s own right as a progeny of Lisp. The “R7RS large” language then adds the useful features of larger languages like Python or Common Lisp as a layer on top of the “R7RS small” language.The current chair of the R7RS working group is Daphne Preston Kendal, and is often on Mastodon as <a class="u-url mention" href="https://chaos.social/@dpk" rel="nofollow noopener noreferrer" target="_blank">@dpk</a> .

TariqFinally got to chapter 14 of the <a href="https://mastodon.social/tags/lisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#lisp</a> course ... people say this is the power of lisp.So far what I like about lisp:* simple syntax, so not a lot to learn to read others code* some constructs hit sweet spot of simple vs general eg DO, COND, LAMBDA* simple conceptual model (almost everything is a list)What I don't like (i'm a beginner)* some stuff breaks "everything is a list" model* Common Lisp is not minimal, includes overlapping and legacy stuffdoes <a href="https://mastodon.social/tags/scheme" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#scheme</a> address this?

Digital Mark λ ☕️ 🕹 🙄I can't easily publish all the source for these at present, it's just such a mess and ties through multiple libraries, other programs, and test code. Making a Scheme "binary" is the only reasonable way out. And I can't use my full app build, because it has no UI, just command line.Thus my Motie Engineer thing. <a href="https://mdhughes.tech/2019/11/22/adult-engineer-over-optimization-as-the-motie-problem/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://mdhughes.tech/2019/11/22/adult-engineer-over-optimization-as-the-motie-problem/</a> <a href="https://appdot.net/tags/scheme" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#scheme</a>

WolfI see <a href="https://hachyderm.io/tags/HelixEditor" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#HelixEditor</a> is getting a built-in language (eventually, I don’t know when, and I don’t have links to information about it). The language will be a <a href="https://hachyderm.io/tags/Scheme" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Scheme</a> called Steel. Steel is inspired by <a href="https://hachyderm.io/tags/RacketLang" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RacketLang</a> and written in Rust. I’ve written small programs in Racket and don’t much like it. I find them hard to understand when I come back to them later. Probably that’s just lack of experience. Adding a built-in language is a really good thing. Picking a Scheme is almost certainly a great choice, despite my feelings. If I do settle on Helix and if I do end up scripting it, maybe I’ll end up liking Scheme more. As far as I’m concerned, this addition to Helix can’t come soon enough.

Digital Mark λ ☕️ 🕹 🙄If I let it grind longer (iterations 400%), I get a filled-in thing like those donjon generators. But I don't like that much, it's too Gygaxian paper-thin-walls like.
