It was also clever to output to SVG: one of the trickiest for beginning CL can be to get a GL window to work... Is not that is super hard, I just find that it is an common failure vector (there's always something like a library that is missing or something like that).
Could be cool to include instructions to run something like live-server [1] (or some CL alternative) to get instant feedback on a browser window :-)
Always look forward to more Lispy ShowHNs. On another note, I am learning common lisp too, but I do not currently get how to make standalone projects. I tried quickproject but most of the time I remain confused. Is there a good explanation of this stuff online?
Currently I stick with (load "lisp-file"), with one main.lisp (I come from the C world) which calls everything else, but it is not really scalable nor really professional. Something like cargo or lein could work wonders!
If you're willing to spend $26, I recommend this short ebook: https://www.darkchestnut.com/book-common-lisp-application-de... It basically gets you setup to create and deploy a production binary with minimal pain while meeting several professional-level expectations, though of course there's lots of tweaking you can do later on and there are always professional differences of opinion for substitutions... The gist of the book's project setup though is that you use ASDF to define your system (similar to a clojure defproject) and its bundled UIOP library for anything interfacing with the OS, qlot to pin versions of your dependencies, tell quicklisp about your local system so while developing you can make wide changes and just reload the system through slime with ql itself, use buildapp to simplify building exes, and use the venerable Make as a wrapper to do builds/cleans/deploys/tests in one step.
Apart from that and the resources others linked, read the ASDF manual: https://common-lisp.net/project/asdf/#documentation That home page also points to other useful things to know about...
Last piece of generic advice... It's often best to read primary sources. Make CLHS your bible, Steele's cltl2 is also great.
Basically Quicklisp is your CL package manager, and ASDF is your makefile.
Another great introduction to Lisp is this blog post by Steve Losh: https://stevelosh.com/blog/2018/08/a-road-to-common-lisp/
