    This website (and all the author's libraries) was such a refresher. It has been important for me to not run away from CL (again). At that time, the "official" website, the first Google result for CL looked like this: Fortunately, they revamped it circa 2018: (work mainly due to @mmontone if I'm not mistaken). Since then, the Cookbook was expanded with useful content (it was kind of hard to find up to date information online, on even simple matters like how to build a binary) and we got some useful lists too, like and a list of (current, existing) companies: Hopefully it's easier than ever to have your questions answered and start hacking in Lisp!

    Another very helpful resource by Fernando was his state of CL ecosystem: It really helped have an overview of the ecosystem, pick libraries and work on consolidation. I compiled one for 2020 here:

  • Is there any company still use Lisp in their production?
    1 project | | 19 Sep 2021
    Yes, many, here some examples:, some old and some new. Google (ITA Software for airplane reservations, they power Kayak, Orbitz and other popular websites, they contribute to the SBCL implementation), Quantum computing companies, PostgreSQL with the pgloader tool, Keepit (a cloud backup provider), Sberbank (a russian bank), Boeing (they use Allegro CL's FNS server on the Boeing 747 and 777 airplanes), Doremir (the company that builds the Scorecloud app: you sing, whistle or play your instrument, it writes the music score), etc
  • Some thoughts about raising the profile of Lisp
    6 projects | | 31 Aug 2021
    A lot has gone wrong in terms of achieving high adoption, but specifically about something going wrong with rallying around CL, I don't think anything went wrong. No more are Maclisp, Interlisp, Lisp Machine Lisp, Zetalisp, Franz Lisp, Portable Standard Lisp, Spice Lisp... They were all slain or subsumed by Common Lisp. (You might have seen Franz elsewhere in this thread; rather than continuing it Franz, Inc. just developed Allegro Common Lisp separately. Spice Lisp meanwhile changed to become a CL implementation, became CMUCL, which was later forked into the now most popular implementation SBCL.)

    Le Lisp/ISLisp are interesting European competition that didn't fall in line, but I don't ever hear about them, I only know they exist/existed, they might nowadays be effectively dead for all I know. Emacs Lisp is probably the biggest success in not caving to CL. Not big enough to constitute anything "going wrong" though.

    I think your perception is wrong in two ways. First is the idea that Scheme and Clojure are somehow "variants" or "dialects" of Lisp. Scheme was never a Lisp dialect, it was instead described as a "Lisp-like". Also notice neither Scheme nor Clojure even have "Lisp" in their name, unlike all those other languages that got eaten by CL. "Lisp" meant something, and "Common Lisp" unified that meaning and I think deserves to be synonymous with "Lisp"; many writers have treated it that way. But Common Lispers are giving up that fight, because it's tiresome but also an understandable confusion not helped by Scheme or Clojure's attempts at capitalizing on some primordial idea about the good name of Lisp or whatever drives them to associate with the term. (#lisp in Freenode used to be only for Common Lisp, now in Libera #lisp is for all Lisp-likes and CL has its own channel.) Anyway, Scheme and Clojure have happily had their own evolution and separate largely incompatible s-expressions. I don't think their continued existence is a flaw against CL any more than another random programming language would be. One aspect of Clojure that might sting a little is that its entire reason for existing was because the author couldn't win political fights about having CL in production instead of the JVM.

    The second way I disagree with your perspective is on prevalence. Scheme has had some success in teaching (mostly thanks to SICP) though Common Lisp was/is also used similarly at various places, however I think that's hurt [Common] Lisp more than anything. (Basically CL gets taught like Scheme, and so whether CL or Scheme is used students come away thinking they "know Lisp" without ever really having seen its OOP power, its handling of types, its condition system, its easy-to-define macros, let alone the trivial things like LOOP or SETF that make imperative programming possible and easy. It's like C++ classes that teach it as C-with-classes, but worse.) Scheme has also had success as GNU's official extension language (with Guile, which goes a ways beyond standard Scheme to be useful) and you see Scheme pop up in places like GIMP plugins. Racket is the most successful modern Scheme, but it has gone waaaay beyond standard Scheme and slowly seems to be becoming as large as CL. Real stuff is made with it, not just education stuff, but I'm less familiar with what's going on. It may yet eat CL's lunch.

    Clojure of course has been a rising star and has enjoyed a lot of success in real stuff. It's popular, it's fashionable, and in terms of projects-per-second your perception is probably right that it's more widely used than CL right now. Where I would draw disagreement is in total pound-for-pound code that's Out There. CL has the benefit of decades of existence, so for example has been developed for a long time and is made of several million lines of CL code, and that's just one project. If you only used "active" (i.e. someone executed it over last month) code perhaps there's enough Clojure out there now to be an interesting race though there's no way to really tell; if you allow for all the CL that has been written and is no longer run, I don't think there's any contest, CL has such a rich history. (A random application being Mirai with demo -- has there ever been a 3D modeling program written in Clojure? Will there ever be?) is an ongoing collection of companies known to be using CL. In terms of "industries", right now quantum computing companies seem particularly drawn to CL. Symbolic math historically also, with Maxima and Axiom being modern still-working/developed code bases. (The latter is a million lines of literate CL.)

    But drawing on legacy again rather than last-few-years stuff, an old quote by Kent Pitman seems relevant: "Please don't assume Lisp is only useful for Animation and Graphics, AI, Bioinformatics, B2B and E-Commerce, Data Mining, EDA/Semiconductor applications, Expert Systems, Finance, Intelligent Agents, Knowledge Management, Mechanical CAD, Modeling and Simulation, Natural Language, Optimization, Research, Risk Analysis, Scheduling, Telecom, and Web Authoring just because these are the only things they happened to list." We can of course add more things to the list if that would help, like Mars Rovers or video games, has a few more, in recent news I learned about and was open-sourced in 2019. Lisp is in a lot of places all over the world (it's had quite a legacy in Japan even), but not the most fashionable stuff, so it's also understandable that many people haven't heard about it, realized they're using it, or heard people talking about it.

    For those interested, today we have a source which references some present companies that use CL in production. It is by no means an official one, we collect data when we find it, but it makes our answer to "who uses CL?" way better than only 2 years ago: Google (still, with ITA Software, people from Google contribute heavily to SBCL), Intel (for the Tofino programmable chip, all quantum computing companies (the new AI?), Boeing, web companies (the new OSS app Screenshotbot), cloud providers (keepit), music products (the awesome ScoreCloud app), banks (russian Sberbank), financial analytics (Ravenpack), etc. Several of them are still hiring.
