awesome-lisp-companies VS kandria

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 debugging 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.

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/

Everyone, if you don't have a clue on how's Common Lisp going these days, I suggest:

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)

Examples (for Common Lisp, so not citing Emacs): reddit v1, Google's ITA Software that powers airfare search engines (Kayak, Orbitz…), Postgres' pgloader (http://pgloader.io/), which was re-written from Python to Common Lisp, Opus Modus for music composition, the Maxima CAS, PTC 3D designer CAD software (used by big brands worldwide), Grammarly, Mirai, the 3D editor that designed Gollum's face, the ScoreCloud app that lets you whistle or play an instrument and get the music score,

but also the ACL2 theorem prover, used in the industry since the 90s, NASA's PVS provers and SPIKE scheduler used for Hubble and JWT, many companies in Quantum Computing, companies like SISCOG, who plans the transportation systems of european metropolis' underground since the 80s, Ravenpack who's into big-data analysis for financial services (they might be hiring), Keepit (https://www.keepit.com/), Pocket Change (Japan, https://www.pocket-change.jp/en/), the new Feetr in trading (https://feetr.io/, you can search HN), Airbus, Alstom, Planisware (https://planisware.com),

or also the open-source screenshotbot (https://screenshotbot.io), the Kandria game (https://kandria.com/),

and the companies in https://github.com/azzamsa/awesome-lisp-companies and on LispWorks and Allegro's Success Stories.

> but there doesn't seem to be one that really stands out as pragmatic, industrial

disagree ;) This industrial language is Common Lisp.

Some industrial uses:

- http://www.lispworks.com/success-stories/index.html

- https://github.com/azzamsa/awesome-lisp-companies/

- https://lisp-lang.org/success/

Example companies: Intel's programmable chips, the ACL2 theorem prover (https://royalsocietypublishing.org/doi/10.1098/rsta.2015.039...), urban transportation planning systems (SISCOG), Quantum Computing (HRL Labs, Rigetti…), big data financial analysis (Ravenpack, they might be hiring), Google, Boeing, the NASA, etc.

ps: Python competing? strong disagree^^

and of course, a quite recent list of companies, in addition of LW's success stories page: https://github.com/azzamsa/awesome-lisp-companies/

Hey there, newer member of the first group here. Please see https://github.com/azzamsa/awesome-lisp-companies/ to update your meta-comment. So, is CL used in the industry today, yes or no?

Personal note: I much prefer to maintain a long-living software in Common Lisp rather than in Python, thank you very much. May all the new programmers learn easily and all the teams have lots of ~~burden~~ work with Python, good for them.

Common Lisp has many industrial uses though.

industrial theorem prover, design of Intel chips, quantum compilers...

and little me, being more productive and having more fun than with python to deploy boring tools (read a DB, format the data, send to FTP servers, show a web interface...).

A recent, notable game made in Lisp is Kandria: https://store.steampowered.com/app/1261430/Kandria/ / https://github.com/Shirakumo/kandria

Those two are definitely not incompatible. Take Karia[0] for example, which is fully Free Software[1].

I’ve seen a 1 person team support steam deck controls with a game written in lisp kandria. The battlebit devs have much better tools supporting steam deck using the unity engine. The controls for the steam deck is definitely not the main reason to abandon Linux, the anti cheat stuff seams to be the only thing in the way.

I don't know about "best", but the work that the Kandria dev has put into CL libraries to create his game has been impressive to see.

For what it's worth, I'd take a look at Common Lisp. It's perhaps less functionally-minded than OCaml, but I don't think it's fair to call it imperative. You'll encounter similar-looking patterns. There aren't loads of games for CL, but I've heard Kandria is super (https://github.com/Shirakumo/kandria), as well as being a great example project.
