Any help I would give is “just use eMacs”, seriously, switch, even if just for lisp. I used to try making lisp work in other editors as I’d had a lot of bad experiences with eMacs before (Google the language Mozart oz) and in the end I just gave up and tried using lisp in eMacs and… it was the path of least resistance. Also I do not recommend intellij products, even for the languages they’re meant for, in my day job I write python and pycharm does not work reliably with the tooling and infrastructure we have to use and even if it does temporarily it breaks on each update. Save yourself the headache, use eMacs for lisp.

With the predicate, you can leave out the if. You can use the null function to see if something is eq to nil. (defun game-over-p (lives scrambled-sitcom) (or (<= lives 0) (null (position #\_ scrambled-sitcom))))

In the game function, this snippet will eliminate some repetition (let ((letter (get-letter guessed-letters))) (game :sitcom sitcom :lives (if (null (position letter sitcom)) (1- lives) lives) :guessed-letters (cons letter guessed-letters)))))

This isn't a critique of your code but here's my take on the game function. (I'm learning too, which is why I'm watching your vids) (defun game () (let* ((options '(rock paper scissors)) (cpu-choice (nth (random (length options) (make-random-state t)) options)) (player-choice (get-player-choice options))) (format t "You: ~A, Cpu: ~A~%~A~%" player-choice cpu-choice (case (winner cpu-choice player-choice) (draw "It's a draw!") (cpu "You lose") (player "You win!") (otherwise "Error"))))) I used case there. I hope it doesn't have errors.

@lispymath I’m glad you’re having fun! It’s good to be thinking in Common Lisp idioms so early.

How so?

@@NeilMunroI watch the videos to learn something useful, not for watching someone else errors, I make mines more easy than follows yours! Thank you anyway to ask!

I like to show that even senior engineers make mistakes and get things wrong in the process. But if that’s not you thing, I get it, thanks for watching anyway.

I’m sorry, I don’t think I understand what you’re asking? For the language or my lessons?

Thanks, I take corrections and publish them online, but you know, you can also make your own video and fix what you think is wrong :)

I was a big vim user for years and while I was trying to get set up with Common Lisp what I was ready about what the experience should be and what I was actually experiencing was different. I tried using slimv or something like that to emulate the experience but it was so brittle and often times wouldn’t work for me. So, having had some experience with eMacs at university (a programming language known as Mozart/oz or I think more accurately Oz with the Mozart programming system) I was not keen to go back to it, but I owed it to myself to try and after a while something clicked, the idea that there’s an interpreter sitting behind the scenes waiting for you to compile functions and test things immediately without switching contexts (even to switch to a buffer with a terminal in it) became just… something I did, without thinking. Evaluating what something did became just a natural part of writing a function, instead of running the program as a whole, run the unit you just wrote. It is, I suppose, a way to get a gist of how what I just wrote works without necessarily having to immediately write a unit test or run the whole program to see if it worked, tests may have some complicated setup, running the program may take time, the repl may already have state and other information ready to do a quick test with, and even if not, I can use the repl to write out what would become a unit test, I do sometimes find the code I test in the repl becomes a unit test, eventually! It soon became muscle memory and I apologize if sometimes it isn’t clear what is happening, it’s sometimes just an autonomic action!

I like making them, but I changed jobs and so im finding myself with less free time as I did, I’d like to go back to them, and will try to when I can

If I may ask, what topic would you like to see next, if there was another video?

@@NeilMunro oh, I'm not sure. I think I'd like to learn more about practical things, like http libraries and json parsing or SQL libraries and the like, or working with quicklisp, asdf, Roswell etc. But what I most like about your videos is the fact that you sound to me like you really enjoy making them and I find that infectious :)

I’ve been using vim since the start of my career as there was a list of approved editors where I worked… I’m institutionalised now and can’t use anything else.

@@NeilMunro I can understand that and I know that there are many people who adore Vim. I believe most of them are probably touch typists which is a factor perhaps. But for me as a ten finger hunt and pecker the presumed advantages of Vim are lost. There is also the "modal" problem that I just can't seem to get past, but as I said earlier, to each his own.😬

Oh aye, I’m totally a touch typist with a config I’m always tweaking and making work for me more… although I will say, learning to touch type and finding and editor that damn near becomes an extension of your body is a good investment. I love not having to be able to think about my editor… what I want flows into the buffet as quickly as I can type it

@@NeilMunro Hey, when you're right, you're right. I know that it would be a good idea for me to learn to touch type, but at my age, breaking the old bad habits would require enormous effort, and apparently I'm just a bit to lazy to do it. Sigh. What is one to do?

The typing of the dead 🤣 it’s a wonderfully weird touch typing gsme

I do add single inheritance later, yes, but I think the solution is much simpler…

Have an absolute wonderful day, I’m so glad something I may brought you some joy!

I’m sorry it’s a bit small for you, I only really had a limited set up and it was huge for me. It’s hard to know large a font is large enough. I’m slowly collecting all the code and publishing it on my blog so if there’s something too small eventually you’ll be able to zoom into a written version.

@@NeilMunro That's great thank you, I hope you'll be able to make more videos, I'm looking forward to them. 👍

I have been adjusting to a new role and recovering from a few rounds of covid but I’ve begun planning some new videos, but I do want to make sure I spend time writing the companion blog pieces too, so everything can be accessible if my recording falls short in some ways

Plan, yes, but it’s finding the time, my job changed, and I caught Covid three times which affected my voice quite a bit

@@NeilMunro Thanks for all the videos you upload. Now, recording video is a very minor thing. I just hope you to recover. I don't know when the COVID-19 will disappear. Please wear a mask and take precautions.

What topics do you feel are missing? I’m thinking of how to dump a lisp system to disk and how to have it automatically run a function, but that wouldn’t be a very long video.

@@NeilMunro I wanna to see more applications from common lisp, also some technique to build a software using common lisp. I come from a background of C/C++/Java/C#, If I could use common lisp to provide part of services, then recommending it to other teammates is easier. I know Grammarly using common lisp to construct their part of services, which inspaired me to learn some common lisp. Before this, I learnt some scheme/racket, but I don't have an idea how to apply them to the real world.

RavenPack also use Common Lisp, so there’s another commercial entity using it. I’ve never worked commercially with Common Lisp because no company I’ve worked in has used it, the one company that had used lisp sold its lisp division to another company before I started with them. I’ll have a think what more I could add to the series then.

It works quite differently than it does in most other programming languages but there’s a way to do that. It could make a short video but may still be useful

That’s a great tip and thanks for sharing it, I think I remember it hit upon this issue myself but simply removed the alias and the more I used eMacs the less I used sbcl in the terminal. If I may, can I put this tip on my website as it seems pretty useful and as I (slowly) compile my videos into written tutorials it seems this could be a great little tip on its own.

@@NeilMunro yes, sure. documenting how to get to a working installation is always tricky because there are so many different systems :/ and it can be quite discouraging for the beginner if it doesn't work. I suppose that's one reason why docker was invented.

I typed :vs to vertically split the buffer and pressed ctrl and while holding it pressed w twice

@@NeilMunro Thanks man.

You’re welcome

You're welcome!

I'll test it in the next few days, but I belived it's installed by default, will check!

@@NeilMunro Same problem figuring out Slynk. Mine's not installed by default

I certainly do!

If you have a sample implementation I’ll add it to my documentation

It’s a bug I became aware of and am no longer using the same software, I switched to something else

@@NeilMunro ah ok

Yeah there was a video editing tool I used where the audio and video were recorded by two different apps and for whatever reason in the final edit it eventually became out of sync. I am going back and creating companion written pieces to help with this (a long task however!) nmunro.github.io/blog.html I’ll eventually get them all transcribed and when I do videos again it’ll be scripted and blogged first with the video following the blog so if there’s upload or editing issues there will be an original written doc for reference:)

Thanks, I have a video I’m working on but I’m also writing companion blog posts for each video so that there’s more context and code snippets, you can read them here: nmunro.github.io/nmunro.github.io/blog.html

Ah that’s helpful to know, I don’t speak Japanese but in Scot’s Gaelic there’s no words for yes or no, there’s “tha” for “is/are” or “chan eil” for “isn’t/aren’t”. Aren’t languages and culture fun?

Great to hear!

@@NeilMunro I failed the class unfortunatly, many things happened at once sadly, but still a big thanks! :D

I’m sorry to hear that, I hope everything has calmed down for you though?

@@NeilMunro Yep, going good so far this semester! :D Luckily we're not doing LISP anymore for that subject and it has changed to Python, thank goodness! XD
