#LuaLang is probably my fav imperative language and #RacketLang or #SchemeLang my fav functional one. Can't decide between Racket and Scheme, I want to like Scheme more but I have much more experience with Racket.

R7RS Large has seen a new release and now #SchemeLang has nested defines.
I was reading it and was like, wasn’t that there forever? Then I remembered I been programming in #RacketLang 😹😹😹 -

The official steering committee of the Scheme programming language is calling a vote to replace themselvesQuoting the memo:
The outgoing Steering Committee was elected in 2009 and successfully oversaw the production and ratification of the R7RS small language report until 2013. Unfortunately, during the protracted initial development of the R7RS large language after that, it fell dormant.
The current Scheme Working Group resolved in September 2025 to ask the Steering Commitee for a new election because it felt that after such long dormancy the outgoing Steering Committee was no longer able, as a group, to make and implement decisions effectively.
The Scheme standardization process charter says, ‘The Steering Committee itself shall establish procedures for replacing its members.’ The outgoing Steering Committee unanimously decided to delegate this task to the current Working Group. The Working Group has very closely modelled the procedure to be used this time on the procedure used last time.
The Working Group has written a statement to candidates and voters explaining what it hopes for in a new steering committee.

There are some issues with it(it shoudl ignore newlines, and it should run the hello world from wikipedia, but it doesn't do either) but here's my #brainfuck interpreter written in #racketlang . I do provide a link to a hello world it does run, showing it's not completely wrong.

I see #HelixEditor 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 #Scheme called Steel. Steel is inspired by #RacketLang 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.

Are you a Lisper? If yes, What made #lisp special in your view?
@lxsameer a few things:
- absolute minimum amount of syntax, makes it very easy to understand how the computer sees each part of the program, makes it easy to implement your own parser if you want to.
- the ability to define your own evaluator for Lisp syntax, also made considerably easier than other languages due to the minimal syntax. This also makes it easy to develop your own tooling, or to modify existing tooling for the language, which brings me to the next point…
- macro programming: the ability to hack the Lisp compiler itself so that it can run your own evaluator. This allows you to introduce language features when and where you need them, like linting, type checking, literate programming, alternative evaluation strategies (e.g. lazy evaluation, or concurrent evaluation), etc.
- functional programming: it is based on the mathematics of lambda calculus, which is a very elegant way of defining algorithms and computation. It is also a computer for the “untyped lambda calculus“ which can implement any other typed lambda calculus as a system of macros.
- homoiconicity, again a feature of the minimal syntax, allows you to express programs as data, and data as programs. This is very useful for serialization and transport across multiple computers.
- REPL-based development, which is a feature many languages have nowadays (although Lisp invented this feature), allows for rapid prototyping and easier debugging.
- stability: Lisp languages like Common Lisp and Scheme have changed very little throughout the decades as there is no need to change them. Macro programming makes it so that you don’t need too add new language features all the time, language features become extensions you can import into your project.

My 8 year old son has fallen in love with this old laptop that honestly isn’t useful for that much as the speed and wifi is so slow.
But he says he wants to learn how to code on it.
@codemonkeymike yes, I would recommend learning Racket. The Racket language is relatively lightweight compared to modern app development frameworks such as VSCode so runs nice and fast on older hardware, and it is designed specifically for teaching coding. There are some nice books aimed at kids for teaching Racket as well:
It is about as easy as learning BASIC was when I was a kid.

"While the new curriculum begins in Pyret, which is similarly designed for teaching purposes, it will quickly transition to Python in the first course. Python does not have anything similar — students must be taught complex features upfront, before they learn the design skills to cleanly and effectively use those features."

"The new courses will primarily teach Python, and the college claims it is an added bonus that Python “is currently the most requested language by co-op employers.” But we should not teach a language simply because it is currently popular in industry — we must choose a language with real pedagogical merit. Racket was chosen because it has “teaching languages” that can gradually introduce features as students are taught the relevant design principles."

“Question for lispers with experience: If you should start to learn a LISP style language today, which one do you pick up? Why?”
@syntaxerror The R7RS “Small” Scheme standard is roughly 80 pages, so you can learn about all of the language features very quickly. I love it because of it’s minimalism, it is my preferred language.
My take on it is that the “Small” Scheme standard is perfectly designed to construct larger programming languages with more features. One such language is R7RS “Large” Scheme, but you could theoretically use it to implement Common Lisp, Python, JavaScript, or any other language.
The R7RS “Large” standard is still being discussed (10 years after “small” was ratified), but it relies heavily on the “Scheme Request For Implementation“ (SRFI) process to fill out features. The larger portion of the R7RS “Large” standard is already ratified and published, so it is still useful even though it is not complete.
There are many Scheme implementations, but I recommend Guile, as it is almost completely R7RS-Small compliant, and has a ton of other useful features that come with it out of the box. So if you need, for example, a quick web server, or a way to search your filesystem, Guile has modules for that.
Another good batteries-included Lisp is Racket, which is a larger language built on top of Chez Scheme (an R6RS Standard Scheme implementation). You can easily install the R7RS Scheme language pack on Racket and write your code in Scheme as you read through the R7RS standard document.
Both Guile and Racket/CS (Chez Scheme) not only have many useful features, but compile to binary code that runs extremely fast for a high-level language.
Also, if you haven’t already, try to learn to use Emacs.

Data Integrity via Smart Structs
by David Storrs
Structs in Racket should be more than dumb data storage. They should be data models in the sense of MVC programming; they should ensure that their contents are valid according to your project’s business rules and they should make it easy to do common operations such as storing to a database or generating a struct from data of another type such as a database row or user input field.
The struct-plus-plus module makes this easy. It allows you to place contracts on individual fields, specify business rules that ensure integrity between fields, easily create converter functions, and much more, with all of these things being part of the struct definition and therefore in one easily-referenced location. Come see how it all works and how you can simplify your code with struct-plus-plus!

keyring: Uniformly Access Secrets
by Sam Phillips
Hardcoding passwords in your programs is bad. Using secure password stores are good. Keyring is a Racket library that allows programs to access different password stores using a simple interface.
