And 2022 is over. The Common Lisp language and environment are solid and stable, yet evolve. Implementations, go-to libraries, best practices, communities evolve. We don’t need a “State of the Ecosystem” every two weeks but still, what happened and what did you miss in 2022?
This is my pick of the most exciting, fascinating, interesting or just cool projects, tools, libraries and articles that popped-up during that time (with a few exceptions that appeared in late 2021).
This overview is not a “State of the CL ecosystem” (HN comments (133)) that I did in 2020, for which you can find complementary comments on HN.
I think this article (of sorts) is definitely helpful for onlookers to Common Lisp, but doesn’t provide the full “story” or “feel” of Common Lisp, and I want to offer to HN my own perspective.
And, suffice to say, I tried to talk about the most important things, but this article (of sorts) is by no means a compilation of all new CL projects or all the articles published on the internet. Look on Reddit, Quicklisp releases, Github, and my favourite resources:
- Awesome-cl - a curated list of libraries (there might be more than you think)
- the CL Cookbook
If I had to pick 3 achievements they would be:
- SBCL developments: SBCL is now callable as a shared library. See below in “Implementations”.
- a new 3D graphics project: Kons-9: “The idea would be to develop a system along the lines of Blender/Maya/Houdini, but oriented towards the strengths of Common Lisp”. And the project progresses at a good pace.
- CLOG, the Common Lisp Omnificent GUI. It’s like a GUI framework to create web apps. Based on websockets, it offers a light abstraction to create fully-dynamic web applications, in Common Lisp. It has lots of demos to create websites, web apps, games, and it ships a complete editor. For development, we can connect our Lisp REPL to the browser, and see changes on the fly. The author had a similar commercial product written in Ada, discovered Common Lisp, and is now super active on this project.
Let’s go for more.
Thanks to @k1d77a, @Hexstream, @digikar and @stylewarning for their feedback.

A newcomer to Lisp came, asked a question, and suddenly he created a super useful rendering of the specification. Check it out!
- 🚀 Common Lisp CommunitySpec (CLCS) - a rendition of the Common Lisp ANSI Specification draft.
- Github: https://github.com/fonol/cl-community-spec
- It is readable, it has syntax highlighting for code snippets, an interactive search bar, it looks modern, it is open.
But that’s not all, he also started work on a new Common Lisp editor, built in Rust and Tauri, see below.
We continue to enrich the Common Lisp Cookbook. You are welcome to join, since documention is best built by newcomers for newcomers.
- New CL Cookbook EPUB and PDF release - mainly readability and file format improvements - thanks to the 13 contributors
A resurrected project:
- the revamped Common Lisp Document Repository (CDR) site, “a repository of documents that are of interest to the Common Lisp community. The most important property of a CDR document is that it will never change”
- I am creating a Common Lisp video course on Udemy 🎥
- read more about my motivation and follow the project on Github: https://github.com/vindarel/common-lisp-course-in-videos/

New implementation! It’s 2022 and people start new CL implementations.
- LCL, Lua Common Lisp - The goal of this project is to provide an implementation of Common Lisp that can be used wherever an unmodified Lua VM is running.
- not a complete implementation.
They are doing great work to revive a Lisp machine:
Medley Interlisp is a project aiming to restore the Interlisp-D software environment of the Lisp Machines Xerox produced since the early 1980s, and rehost it on modern operating systems and computers. It’s unique in the retrocomputing space in that many of the original designers and implementors of major parts of the system are participating in the effort.
Paolo Amoroso blog post: my encounter with Medley Interlisp.
I won’t list expired job announces, but this year Lispers could apply for jobs in: web development(WebCheckout, freelance announces), cloud service providers (Keepit), big-data analysis (Ravenpack, and chances are they are still hiring)), quantum computing (HLR Laboratories), AI (Mind AI, SRI International), real-time data aggregration and alerting engines for energy systems (3E); for a startup building autism tech (and using CLOG already); there have been a job seeking to rewrite a Python backend to Common Lisp (RIFFIT); there have been some bounties; etc.
Prior Lisp experience was not 100% necessary. There were openings for junior and senior levels, remote and not remote (Australia for “a big corp”, U.S., Spain, Ukraine…).
Comes a question:
I remind the reader that most Lisp jobs do not have a public job posting, instead candidates are often found organically on the community channels: IRC, Twitter, Discord, Reddit… or teams simply train their new developer.
In 2022 we added a few companies to the ongoing, non-official list on awesome-lisp-companies. If your company uses Common Lisp, feel free to tell us on an issue or in the comments!
For example, Feetr.io “is entirely Lisp”.
Lisp was a conscious decision because it allows a small team to be incredibly productive, plus the fact that it’s a live image allows you to connect to it over the internet and poke and prod the current state, which has really allowed a much clearer understanding of the data.
They post SLY screenshots on their Twitter^^
We’re using CL in prod for an embedded system for some years now, fairly smooth sailing. It started out as an MVP/prototype so implementation was of no concern, then gained enough velocity and market interest that a rewrite was infeasible. We re-train talent on the job instead.

There has been outstanding work done there. It is also great to see the different entities working on this. That includes SBCL developers, Doug Katzman of Google, and people at HRL Laboratories (also responsible of Coalton, Haskell-like on top of CL).
Have you ever wanted to call into your Lisp library from C? Have you ever written your nice scientific application in Lisp, only to be requested by people to rewrite it in Python, so they can use its functionality? Or, maybe you’ve written an RPC or pipes library to coordinate different programming languages, running things in different processes and passing messages around to simulate foreign function calls.
[…] If you prefer using SBCL, you can now join in on the cross-language programming frenzy too.

But an awesome novelty of 2022 is Kons-9.
Kons-9, a new 3D graphics project
🚀 A new 3D graphics project: Kons-9.
The idea would be to develop a system along the lines of Blender/Maya/Houdini, but oriented towards the strengths of Common Lisp.
I’m an old-time 3D developer who has worked in CL on and off for many years.
I don’t consider myself an expert […] A little about me: • wrote 3D animation software used in “Jurassic Park” • software R&D lead on “Final Fantasy: The Spirits Within” movie • senior software developer on “The Hobbit” films.

Interfaces with other languages
- py4cl2-cffi: CFFI based alternative to py4cl2.
- it does one big new thing: it supports passing CL arrays by reference. That means we actually have access to numpy, scipy, and friends.
- “If py4cl2-cffi reaches stability, and I find that the performance of (i) cffi-numpy, (ii) magicl, as well as (iii) a few BLAS functions I have handcrafted for numericals turn out to be comparable, I might no longer have to reinvent numpy.” @digikar
- Small update to RDNZL (CL .NET bridge by Edi Weitz)
- forked project, added support for Int16, fixed Int64, re-building the supporting DLLs.
- see also: Bike
- jclass: Common Lisp library for Java class file manipulation
For more, see awesome-cl.
Numerical and scientific
- 🚀 new Lisp Stats release
- “emphasis on plotting and polishing of sharp edges. data-frames, array operations, documentation.”
- HN comments (55)
- ” I’ve been using lisp-stat in production as part of an algorithmic trading application I wrote. It’s been very solid, and though the plotting is (perhaps was, in light of this new release) kinda unwieldy, I really enjoyed using it. Excited to check out the newest release.”
- “For example, within Lisp-Stat the statistics routines  were written by an econometrician working for the Austrian government (Julia folks might know him - Tamas Papp). It would not be exaggerating to say his job depending on it. These are state of the art, high performance algorithms, equal to anything available in R or Python. So, if you’re doing econometrics, or something related, everything you need is already there in the tin.”
- “For machine learning, there’s CLML, developed by NTT. This is the largest telco in Japan, equivalent to ATT in the USA. As well, there is MGL, used to win the Higgs Boson challenge a few years back. Both actively maintained.”
- “For linear algebra, MagicCL was mention elsewhere in the thread. My favourite is MGL-MAT, also by the author of MGL. This supports both BLAS and CUBLAS (CUDA for GPUs) for solutions.”
- “Finally, there’s the XLISP-STAT archive. Prior to Luke Tierney, the author of XLISP-Stat joining the core R team, XLISP-STAT was the dominate statistical computing platform. There’s heaps of stuff in the archive, most at least as good as what’s in base R, that could be ported to Lisp-Stat.”
- “Common Lisp is a viable platform for statistics and machine learning. It isn’t (yet) quite as well organised as R or Python, but it’s all there.”
- numericals - Performance of NumPy with the goodness of Common Lisp
numericalsis “a high performance basic math library with vectorized elementary and transcendental functions. It also provides support for a numpy-like array object through
dense-arraysand static-dispatch through the CLTL2 API.”
- the post is about numericals, dense-arrays, magicl, numcl, py4cl/2…
- the author’s comparison and wish-list of features for a Common Lispy approach to a (better) Numpy
- MGL-MAT - a library for working with multi-dimensional arrays which supports efficient interfacing to foreign and CUDA code. BLAS and CUBLAS bindings are available.
- hbook - Text-based histograms in Common Lisp inspired by the venerable HBOOK histogramming library from CERN.
- Maxima 5.46 was released.
- “Maxima is a Computer Algebra System comparable to commercial systems like Mathematica and Maple. It emphasizes symbolic mathematical computation: algebra, trigonometry, calculus, and much more.”
- see its frontends, for example WxMaxima.
Call to action:

I don’t have lots of open-source apps to show. Mines are running in production and all is going well. I share everything on my blog posts. I also have an open-source one in development, but that’s for the 2023 showcase :D
🚀 The awesome novelty of 2022 I spoke of in the introduction is CLOG, the Common Lisp Omnificent GUI:
- Native Desktop Executables for CLOG
- CLOG and CLOG Builder Release 1.8 - IDE for Common Lisp and CLOG
- CLOG on Android, APK download
I know of one open-source consequent CLOG app: mold-desktop, in development.
I’m developing a programmable desktop and a bookmarks manager application with CLOG. I think I know one of the things that make CLOG user interfaces so easy to develop. It is that they are effortlessly composable. That’s it for now :)

- Why not: from Common Lisp to Julia
- HackerNews comments (200) (for this post and the post it responds to)
- The author of the first post said he was “migrating from Common Lisp to Julia as [his] primary programming language”. He was starting “to grow increasingly frustrated with various aspects of the language” and the CL ecosystem. Many of his arguments were harsh towards CL and didn’t mention existing better alternatives.
- Two months later, in another blog post, he admits the previous article “was unfair to both languages”, and while “[he] is still mostly using Julia”, “Common Lisp is still on the table for [him]“.
- On LiberaChat, he says he’s back from Julia to Common Lisp: “As of yesterday, I’m back to making libraries in CL. I cannot consider Julia as a serious language anymore, for it has deceived me after 7 years of research.”
- Welcome back and thanks to him for the past and future CL libraries.
