I think you do the best CL stuff on here, now

updated finding: if you set *print-circle* t, and define a long list with repeating elements, you will see that the elements that repeat are not stored as individual elements, but are stored as pointers pointing to the original list item that it duplicated... I guess this changes when you update the element? Anyway, when you print the list in the repl, you will see items that are list as #1YourItem, #2AnotherItem, etc. When the printout gets to the repeating elements, instead of printing them it will show (for example) #1# (if the item is a repeat of the first list item). This really threw me when I stumbled over it. But if you take (nth somenumber yourlist) and somenumber is a repeat item, you will see the correct list item. just an FYI. cheers!

Mr. Lisper, what do you think about doing a series on Data Structures and Algorithms implementation in Common Lisp? I would love to watch that.

You're a mind-reader! I was just thinking earlier about using a circular list, and their dangers. Thank you, for the explainer.

My favorite YT channel 🙂

I'm personally a big fan of this macro. But I mostly use. the iterate library.

Great! Thank you! Could you also show do in more detail?

Definitely do. This is Lisp. It should support anything that is useful to do.

Why would you want public keys to be secrets? They are "public" for a reason. Am I missing something?

Over complicated in my opinion. Is there any tutorial /book which can explain this? what are :initarg and :text ? How to get them populated in IDE? I am using Portacle

This is excellent and will be useful for my first large CL project! Thank you for your work on these videos, I watch every single one.

Interesting. But thats's not from scratch. I was under impression that Auth provider will be in Common Lisp! Authentik is written in Java or Golang i believe.

always happy when you post :)

Great you are back again.

Which IDE to use for Common Lisp? I really don't like emacs and its flavors.

Papers have been written proving that compiled lisp code can be just as fast as C code, especially with statically typed variables and optimal data structures like indexed arrays and vectors.

Good tool for faster solutions while keeping CL.

Thanks!

I love to see the common lisp community growing and getting more active.

so, are we making competition to HTMX?

That's really inspiring, thanks a lot!

so, about the type inference is it exclusive for classes or applies to structs and types with deftype as well?

I love to see a new raise in the common lisp community, is slow and steady, this is the best, because in the last times, it was fast and went as fast as it came, we need time to build an ecosystem that makes lisp great again.

you forgot to talk about CLASP implementation of Common Lisp, targeting LLVM to interface with C++ and compile everything to native, no interpreter and it is being used to work in chemistry for nanotechnology and design nanomachines and molecules.

Excellent, thanks for a short and effective presentation 😊

Do you know of anything like flet for multiplatform (gtk / web/ mobile) implementations usable and integrateable like this from CL ?

I like how emacs org-mode is used to drive the presentation.

Really useful video. I heard about py4cl but didn't use for anything practical yet.

Informative! I was aware of those libraries, but as a CL beginner I needed some perspective. These videos are a public service.

With the _closer-mop_ library in most Common Lisp implementations, you can deny access to a slot by defining the SLOT-VALUE-USING-CLASS method. Your method would check if it's being called by an approved caller (using a special variable that either does or doesn't have the correct sentinel variable, and a macro to define approved accessor functions in such a way that the special variable has the sentinel value), and it would signal an error if it wasn't. A metaclass that uses a custom slot type would give you a place to store the visibility of each slot.

I think the CLOS is a very good OOP system. It's unfortunate that C++ and Java have implemented such schizophrenic notions of classes souring an entire generation on what OOP can be. I used functions quite heavily, but for stateful components in a system (especially when I want dispatch) CLOS is excellent. There are quite a few CLOS books too!

Do you think its possible to use CFFI to interface with the Unreal Engine APIs? I understand it has its own GC...

Excellent approach to teaching! I will imitate it. Thank you!

You're a mind reader, I was thinking about getting dirty with some CLOS earlier today. TFTV!

I'm pretty surprised what CLisp is capable of, but is it safe for production environments ? I'm asking this as a newcomer in the language, because in my whole life I used java and golang for web apps

Also ABCL for Common Lisp on Java...

I'm sure the video title sounds like silly nonsense words to non-programmers 😂 Anyway, good video

How much math would one need to know in order to master lisp?

As someone currently starting with CL, this is very useful. Thanks a lot!

Will you make a video for before, after and around methods?

I think more properly it's a Hindley-Milner type system, used by the whole ML language family, notably OCaml, F# and Haskell.

Very interesting

Did types beat Lisp? Or did Lisp manage to swallow a typed language?

too quiet, even at max volume..

とても良い動画ですね。 Doug HoyteのLetOverLambdaのチャプター2（和訳だと第一章） letoverlambda.com/index.cl/guest/chap2.html#sec_7 の、 まとめを読んだ様な気分。古き良きletとlambdaだけでOOモドキが簡単に 出来て楽しい。特にmake-personのリターンが値の一覧では無くてlambdaの 一覧なのが、なんかファンクショナルで良いですね。ところで、 外側のdefunと内側のlambdaの役割分担は、 ・外側のdefun - インスタンスの作成(new) ・内側のlambda - アクセサとかセッター という風に考えて良いのでしょうか？ また宣言した*person*を削除(delete-person)する様に改変するなら どの様にしますか？ OOとしては足らない機能は何ですか？

Now I understand! Thanks for saving my sanity.

Parabéns!

Why to write a special reader function and use SHELL syntax for config, when you can just LOAD a lisp file with any code holding config values? Usually I just use UIOP:GETENV in a place where confuration value is used and have (LOAD ".local.lisp") which SETF these variables if .local.lisp file exists. In production these env variables are configured in a dockerfile or in the systemd config.

Grazie per l'utilissimo video. E che sorpresa vedere che l'autore è un omonimo Italiano! Un saluto dalla Scozia 👋😊

Very good examples using Portacle. Could you make more videos using Portacle? I am asking it because I know some people who uses Windows who might be interested in Emacs, but never heard about it... And it is a good way to start leading them into the Linux/OpenSource path... Apart from that, when you make new videos about Lisp/Emacs, could you use lighter themes and bigger fonts? Just think about people who are short-sighted and would like to follow your YT channel. Thx.
