Do you know of anything like flet for multiplatform (gtk / web/ mobile) implementations usable and integrateable like this from CL ?
@the-lisper Күн бұрын
No, sorry... The CL ecosystem provides a lot of building blocks, but integration with many platform is a lot of works and requires a bigger community... I think that the best chance is to integrate CL as a shared library (ECL or sbcl-librarian) into some other products outside the CL ecosystem... (or buy LispWorks)

I also really like the idea, Lisp has to find ways to talk to the outside world. This way it can be used to write the core logic and take advantage of libraries that receive a lot of development!

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

Yes, I also think that some context is important when choosing a library!
@amorphousblob2721 29 күн бұрын
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.

Thanks for the tip! I think that one should have strong reason to build such a construction, most of the time I would provide the "public interface" and discourage the usage of the "internal interface". The user may mess up at its own risk. Nevertheless, yeah, it is interesting the one can do whatever he wants!

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!
@the-lisper 26 күн бұрын
Yes, "Object-Oriented Programming in COMMON LISP: A Programmer's Guide to CLOS" and "The Art of the Metaobject Protocol" is the way to learn CLOS!

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

Probably knowing some math may help, it may make you see things in a different way. Nevertheless, it is really not required, one can learn by doing and there are no really prerequisites from math.

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？

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.
@the-lisper 2 ай бұрын
.env file and environmental variables are almost the standard in webapp configuration, you can use the same config directly with your lisp implementation or passing it to docker without changing it

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.

Hello, I would suggest looking at the resources in the various subreddits related to lisp, there is usually a section with tutorial and books. For example you could start from www.reddit.com/r/lisp/ and then looking at the one regarding the lisp you are interested in, for example common lisp ( www.reddit.com/r/Common_Lisp/ ) or clojure ( www.reddit.com/r/Clojure/ )!

As I see over internet, most of time let is outside of defun, not inside. Is there any differencea between two approaches?
@the-lisper 2 ай бұрын
Let-over-lambda means define a function inside another lexical scope, when you call the function you are actually outside that scope but it was not freed because you are still using some references. The outer defun let you "parameterize" the closure, and create basically some "objects"
@oskarwerner2164 2 ай бұрын
@the-lisper But you could create and parametrize objects with let inside, so I still don't understand difference between (let (defun ...) and (defun (let ...)
