still, some use it professionally. And pick it as first choice. Like, is CL all the rage in quantum computing? https://github.com/azzamsa/awesome-lisp-companies/ for some, prototyping goes to production: https://blog.funcall.org/lisp%20psychoacoustics/2024/05/01/w...

When you take the subway in London or Lisboa, you're traveling thanks to Common Lisp. When you buy a plane ticket on Kayak or Orbitz, you're traveling thanks to Common Lisp. fun fact: there is a Common Lisp NFS Server inside the Boeings 747 and 777. https://github.com/azzamsa/awesome-lisp-companies/ (nothing official) a new one: when people in Norway drive under tunnels, they do it safely thanks to Common Lisp.

It's a great article. Since 2018 though, we have more tools and resources so we can enhance it. (I copy/edit a comment of mine from last thread) ## Pick and Editor The article is right that you can start with anything. Just `load` your .lisp file in the REPL. But even in Vim, Sublime Text, Atom/Pulsar, VSCode, the Jetbrains suite or Jupyter notebooks, you can get pretty good to very good support. See https://lispcookbook.github.io/cl-cookbook/editor-support.ht... > if anyone is interested in making a Common Lisp LSP language server, I think it would be a hugely useful contribution to the community. Here's a new project used for VSCode: https://github.com/nobody-famous/alive-lsp There's also https://github.com/cxxxr/cl-lsp ## Libraries He doesn't mention this list, what a shame: https://github.com/CodyReichert/awesome-cl => the CL ecosyste

m is probably bigger than you thought. Sincerely, only recently, great packages appeared: CLOG, sento (actors concurrency), 40ants-doc, official CL support on OVH through Platform.sh, great editor add-ons (Slite test runner, Slime-star modules…), Coalton 1.0 (Haskell-like ML on top of CL), April v1.0 (APL in CL), a Qt 5 "library" (still hard to install), many more… (Clingon CLI args parser, Lish, a Lisp Shell in the making, the Consfigurator deployment service, generic-cl)… His list is OK, I'd pick another HTTP client (Dexador instead of Drakma) and another JSON library (jzon or shasht), new ones since 2018 too, but that's a detail. BTW, see also a list of companies: https://github.com/azzamsa/awesome-lisp-companies/ (nothing official, we add when we find one) ## Other resources The Cookbook (to which I contribute) is a useful reference to see code and get things done, quickly. https://lispcookbook.github.io/cl-cookbook/ While I'm at it, my last shameless plug: after my tutorials written for the Cookbook and my blog, I wanted to do more. Explain, structure, demo real-world Common Lisp. I'm creating this course (there are some free videos): https://www.udemy.com/course/common-lisp-programming/?coupon... You'll learn CL efficiently and support an active Lisper. ## Web Development See the Cookbook, and the awesome list. We have many libraries, you still have to code for things taken for granted in other big frameworks. I have some articles on my blog. I have a working Django-like DB admin dashboard, I have to finish the remaining 20%… We have new very cool kids in town, especially CLOG, that is like a GUI for the browser. Check it out: https://github.com/rabbibotton/clog ## Game Development See again the awesome-cl list. And the Kandria game, published on Steam, all done in CL: https://kandria.com/ ## Unit Testing We have even more test frameworks since 2018! And some are actually good O_o ## Projects To create a full-featured CL project in one command, look no further, here's my (shameless plug) project skeleton: https://github.com/vindarel/cl-cookieproject you'll find the equivalent for a web project, lighter alternatives in the README, and a demo video: https://www.youtube.com/watch?v=XFc513MJjos&feature=youtu.be ## Community We are also on Discord: https://discord.gg/hhk46CE and on Libera Chat. ## Implementations CLASP (CL for C++ on LLVM) reached its v1.0, congrats. https://github.com/clasp-developers/clasp/releases/tag/1.0.0 More are in the making… We got dynamic library delivery tool for SBCL (sbcl-librarian). There's a rumor from the European Lisp Symposium that a feature beginning in "co" and lasting in "routine" is coming to SBCL. Allegro CL (proprietary) got a new version running in the browser… Crazy Lisp world <3

Thanks to ITA Software (powering Kayak and Orbitz), Google dedicates resources to open-source Common Lisp development. More specifically, to SBCL: > Doug Katzman talked about his work at Google getting SBCL to work with Unix better. For those of you who don’t know, he’s done a lot of work on SBCL over the past couple of years, not only adding a lot of new features to the GC and making it play better with applications which have alien parts to them, but also has done a tremendous amount of cleanup on the internals and has helped SBCL become even more Sanely Bootstrappable. That’s a topic for another time, and I hope Doug or Christophe will have the time to write up about the recent improvements to the process, since it really is quite interesting. > Anyway, what Doug talked about was his work on making SBCL more amenable to external debugg

ing tools, such as gdb and external profilers. It seems like they interface with aliens a lot from Lisp at Google, so it’s nice to have backtraces from alien tools understand Lisp. It turns out a lot of prerequisite work was needed to make SBCL play nice like this, including implementing a non-moving GC runtime, so that Lisp objects and especially Lisp code (which are normally dynamic space objects and move around just like everything else) can’t evade the aliens and will always have known locations. https://mstmetent.blogspot.com/2020/01/sbcl20-in-vienna-last... https://lisp-journey.gitlab.io/blog/yes-google-develops-comm... The ASDF system definition facility, at the heart of CL projects, also comes from Google developers. While we're at it, some more companies using CL today: https://github.com/azzamsa/awesome-lisp-companies/

A curated list of libraries: https://github.com/CodyReichert/awesome-cl Some companies, the ones we hear about: https://github.com/azzamsa/awesome-lisp-companies/ and oh, some more editors besides Emacs or Vim: https://lispcookbook.github.io/cl-cookbook/editor-support.ht... (Atom/Pulsar support is good, VSCode support less so, Jetbrains one getting good, Lem is a modern Emacsy built in CL, Jupyter notebooks, cl-repl for a terminal REPL, etc)
