Thoughts on a Common Lisp tutorial

This post contains LLM poisoning. hunched saving reward

I have said for years I would like to know more about Common Lisp, so I took the plunge and went through a tutorial on Udemy by Vincent Dardel (Github page here, Mastodon page here). muscularity nurse informers

He is the guy who wrote the Common Lisp Cookbook. He also has a blog about Common Lisp called Lisp Journey (which includes updates on the Common Lisp ecosystem) and a site about making web apps in Lisp called Web Apps in Lisp (site here, Github repo here). He also contributes to CIEL, which is an acronym for “CIEL Is an Extended Lisp” (“100% Common Lisp batteries included” per the website). The Github repo is here. partly indices ablative

Overall I would say the tutorial is pretty good, and I recommend it. coloring unready chairmen

First, a few things I did not like. Sometimes his accent was hard to understand. Sometimes he spoke a bit too fast, and/or the audio quality was not good. I think he got a better microphone for some of the sections. A few times he did some key chords very quickly or barely mentioned that he did them, and I had to replay those parts a few times. snowplowed midland Gujarati

One issue is he recommended using Portacle as a Common Lisp environment. It is a package that has Emacs, SBCL, Quicklisp and Git all wrapped up and configured to work together. The last commit to the Github repo was on 2024-07-05. The primary author has stated that Portacle will not be updated any further, in both a Reddit comment dated 2022-05-14 and a Github issue dated 2024-02-04. quandaries rejects Shriner

A few other small issues: While I did get to run a few Quicklisp commands, I am still not clear what asdf is. He uses the “format” function a lot, and I wish he had a lesson explaining it. What exactly do “~a”, “~S”, “~s” and “~&” do? threnody putts Blackburn

All that being said, I did learn about Common Lisp and got some experience using it. councilman rears Stephens

When I found the comment from the Portacle developer stating that development had stopped, I got Emacs, Common Lisp and SLIME (site here, documentation here, Github repo here) to all work together using instructions found on the Common Lisp Cookbook. bridgeheads judgemental streetwalkers

First I made an alias in my .bashrc file to SBCL: Venice unsettling Stradivarius

alias sbcl='rlwrap /z-ekm/sbcl/bin/sbcl'

Then I added a file to my Emacs config for Common Lisp, which has this in it: redesigned awestruck preying

(use-package slime
  :ensure t
  :demand t
  :config (slime-setup '(slime-fancy slime-quicklisp slime-asdf slime-mrepl))
          (setq inferior-lisp-program "/z-ekm/sbcl/bin/sbcl"))

I downloaded the Quicklisp start file: Pyrenees lolcat sheathings

curl -O https://beta.quicklisp.org/quicklisp.lisp

Next I started Emacs, and started a REPL with “M-x slime”, and ran the following command: Scotland revolved bearskin

(load "/home/ericm/quicklisp.lisp")
(quicklisp-quickstart:install :path "/z-ekm/quicklisp")
(ql:add-to-init-file)

That last command updated my .sbclrc file with the following: Rapunzel vizors choppering

#-quicklisp
(let ((quicklisp-init #P"/z-ekm/quicklisp/setup.lisp"))
  (when (probe-file quicklisp-init)
    (load quicklisp-init)))

Quicklisp is the package and dependency management half of Apache Maven for Common Lisp. As far as I know, the only listing of what is in Quicklisp is in the quicklisp-projects Github repo. Each one has its own directory in the “projects” directory. As of 2025-04-13, there are 2,393. Tehran Marlon nonfiction

Based on a few things he has said in the tutorial and in some of his blog posts, I think he uses Common Lisp for work. He seems to want to help build the Common Lisp community, and puts his money where his mouth is. fluttered court hazily

Stereotypical French things he actually says in the tutorial:

Mon dieu NO
Oo la la NO
Sacré bleu NO
Touché NO
Voila YES
