Hi! Thanks for the great Scheme overview! I'm using Scheme for more than ten years already; there are several Guile libraries that I developed during the years and still maintain. One of the my libraries that I'm kinda proud of is Guile-SSH that is used in GNU Guix for its offloading feature and some other stuff.

@SystemCrafters 6 месяцев назад

That's awesome! You certainly have made a bunch of useful libraries, thanks for that! The Guile ecosystem definitely needs people like you who are willing and able to flesh out the ecosystem

@ade5324 6 месяцев назад

scheme is perfect programming language to learn programming languages (how they work) currently enjoying "lisp in small pieces" book and half-way though mit 6.001 video lectures, i don't even care that its a niche language anymore, its been a pleasure.

@SystemCrafters 6 месяцев назад

Lisp in Small Pieces is such a great book!

@nazmi3126 6 месяцев назад

I dabbled a little bit in Racket and Common Lisp by following the book Realm of Racket and Land of Lisp. Both great books and in the Lisp family of languages with Scheme. I really like lisp languages - something about all those parenthesis appeals more than 'C-type' syntax.

@capability-snob 6 месяцев назад

Not just tail call optimisation but _tail call elimination_. The difference is that in scheme, it's a property you can rely on, and can happily tail call all day, safe in the knowledge you're not growing the stack.

@SystemCrafters 6 месяцев назад

That's right, I should have referred to it like that. It's a great feature!

@alurma 6 месяцев назад

True

@9s-l-s9 6 месяцев назад

So to the questions at the end: I was recently looking into which lisp I should learn. As I am already using guix, at first scheme seemed great. I also like the general design philosophy of a simpler feature set compared with other lisps. However my end goal would be to have some sort of lisp machine. And I found that actually common lisp currently offers a wider number of apps for this. I can configure stumpwm, nyxt and lem all with the same language. So I started with common lisp.

@SystemCrafters 6 месяцев назад

Common Lisp is definitely a good choice for that. Perhaps if more people learn Scheme we'll see more Scheme-configurable apps of a similar kind. There is the Nomad browser which is like Nyxt for Guile Scheme but I don't know if it's still being developed/maintained.

@9s-l-s9 6 месяцев назад

@@SystemCrafters Yeah, well I am not too happy with Common Lisp. I really would prefer a simple language. Btw, is the course going to be free? (also, the link is not working for me)

@SystemCrafters 6 месяцев назад

The course is paid due to the interactive nature and time involved. It appears Codeberg Pages is down at the moment so my site is unfortunately down :( Hopefully will be back up soon

@gagagero 6 месяцев назад

@@9s-l-s9Common Lisp is simple. It (just like Scheme) has a large standard library, which is where most of the complexity comes from. But if you want to create a Lisp machine of sorts, probably the only way to do that is to load everything into one single CL image, maybe on different threads.

I subscribed to the newsletter partially in hopes of seeing an intermediate scheme course. I hope the beginner one is successful enough to encourage you to run one.

@SystemCrafters 6 месяцев назад

I will definitely run an intermediate Guile course, that's where the real fun will begin! What would you hope to learn from such a course?

@joshuacottrell7225 6 месяцев назад

@@SystemCrafters I'd hope to learn how to move beyond the small (one to three source file) projects to something larger that maybe included an outside package (outside: via a package manager), where macro code goes relative to other code, and maybe utilize a database. What's a step or two beyond Advent of Code problems? That's my initial definition. I'd likely take it (finances allowing at the time of release) if it didn't re-explain syntax, expressions, car/first, cdr/rest, cond, recursion, lambda/anonymous functions, etc.

@SystemCrafters 6 месяцев назад

@joshuacottrell7225 Yep, not re-explaining the basics would be the goal! My early thoughts on an intermediate to advanced course definitely cover a lot of what you mentioned there. I think we'd try to develop a networked application of some sort, enough to feel like it's an approximation of a real world application

@lorensims4846 6 месяцев назад

Very nice, comprehensive, and concise video! I've noticed that you tend to ramble when you're not working from a script. I like this much better. I've been fascinated with Lisp[ ever since I first heard of it in 1980 in Byte magazine when it was introduced as the language of artificial intelligence. Emacs is a good example of what can be done with Lisp. The original version of Emacs was written in MacLisp, a version that featured easy use of macros. In GNU Emacs, Elisp is a version of MacLisp. I understand Gnu is currently looking to convert Emacs to work with Guile to better integrate with the whole Gnu ecosystem because Guile is intended to be THE system-wide scripting language for Gnu. I really like Guile because of its interoperability with C. It's easy to write a C program in Guile and to write a Guile program in C. The idea is to make it easy to add Guile to your application as the application's built-in scripting language, much the way Elisp is Emacs's built-in scripting language. It is a completely different paradigm in programming, much as OCaML, Forth, or even Tcl are. It's good to see different ways to do what you're used to doing to stretch your understanding of programming principles. I've started working with Guile a couple of times and have found it to be quite enjoyable, but somehow I keep getting distracted by something else. I feel that Guile is very important to the Gnu ecosystem and for that reason alone I want to become proficient in it. Thank you for offering the series. It's just what I've been looking for.

Nice! What about Racket? Except for Guix, Racket feels more like a 2024 topic than Scheme. What do you think about Racket?

@TheLittlehuihui 6 месяцев назад

Nice video. What is your opinion on Scheme vs Common Lisp + Coalton ?

@SystemCrafters 6 месяцев назад

Haven't tried Coalton! I'm more of a fan of Scheme than CL, but Coalton is surely interesting.

@abarocio80 6 месяцев назад

Guix is actually my main interest on scheme, but not the only one.

Can we game on Guix yet?

@SystemCrafters 6 месяцев назад

@theena 6 месяцев назад

David, I am hoping to use this year to learn Common Lisp as a first-ish programming language (have experience with some python, some Lua (because I use NeoVim). Would this be a good way to get into Lisp as a whole?

@SystemCrafters 6 месяцев назад

Common Lisp is a perfectly fine language to get started with, you will learn a lot that will transfer to other Lisps

@gagagero 6 месяцев назад

I wouldn't recommend it. Something else that doesn't need as much theory and is more common (like C or Python) would be better for getting core programming concepts down. Even Scheme with SICP would be a better choice.

@alurma 6 месяцев назад

Thanks. For learning functional programming, I think it's better to learn languages tailored for the paradigm, particularly Clojure, Haskell, Erlang, Elixir or OCaml, not Scheme or Lisp. I agree on the other points. Exciting to see Scheme on the Web!

@SystemCrafters 6 месяцев назад

Scheme actually is tailored for the paradigm, its design is directly inspired by lambda calculus. I don't think that a language needs immutable data structures or to refuse binding reassignments to be an effective functional language, it all depends on how you write the code. You definitely can't say the same thing about Common Lisp, though, I would not call that a functional language even though you can program in a functional style.

@alurma 6 месяцев назад

Yeah, we can agree to disagree. I'm not saying Scheme isn't functional. The word has many meanings. Having functional data structures syntactically close in languages like Clojure, Haskell, etc. makes a difference. It's possible to program in a functional style in ANY mainstream programming language (Go, Python, name it), there are ways to achieve this. Scheme makes some things easier (e.g. tail calls are eliminated). Haskell, OCaml, Erlang and Elixir even more so (one could argue that Clojure is a bit different because on JVM it's expensive to eliminate tail calls so Clojure doesn't do it automatically, gotta do yourself). So, I hope you got my idea. If so, we can agree do disagree (or agree to agree, you decide 🙂)

@mattinykanen4780 6 месяцев назад

I code in Haskell nowadays. (As a soon-to-retire academic, I can afford that luxury.) But I arrived there from Scheme: While I loved its delay/force mechanism, I hated how much self-discipline it took to get that code to work... or even to avoid a black hole... Oh how I wish the compiler could ease that burden! But hey, there's this "Hindley-Milner type inference" thingy; maybe it could help? Hence whenever a student asks me about how to get started in functional programming, I mostly suggest starting with Scheme and not Haskell. While types are _extremely_ important, it is easier to learn new stuff one step at a time.

@vikinghornsfromhell 2 месяца назад

When adding the non-free modules to guix, the "guile" scheme fails miserably! So don't waste your time, unless you use the defaults (libre)!

@TheLongestConfidence 2 месяца назад

Clojure has an emphasis on immutable data structures, but *not* pure functions. You should write pure functions wherever possible, just like any other language, but functional purity is not a core philosophy of the language, nor even idiomatic.
