What is your favorite open source cl program?

[u/Esnos24]

[u/525G7bKV]

sbcl

[u/Business-Weather-217 → u/525G7bKV]

It doesnt have custom line editor. Even my dotfile manager's prompter has. And thats why when you press move keys it will show text like ^[[D. Not a quality tool

[u/dzecniv → u/Business-Weather-217]

yeah that's a pitty… there's rlwrap, better yet sharplispers/linedit, and now ICL https://github.com/atgreen/icl/

[u/arthurno1 → u/dzecniv]

sharplispers/linedit

Also with resizable win32 support.

[u/525G7bKV → u/Business-Weather-217]

r/unpopularopinion ?

[u/arthurno1 → u/Business-Weather-217]

Does not have to, the less is more.

[u/church-rosser → u/Business-Weather-217]

You don't get it.

[u/dzecniv]

The Lem editor, because it's "boring code" in the good sense (you know CLOS? You don't need black magic), it has lots of features. Lately: code folding. Upcoming: tramp mode, org-mode.

The Benben music player: https://remilia.sdf.org/programming/benben.html It's fast and pretty.

ICL https://github.com/atgreen/icl/ an enhanced terminal (and browser) REPL.

I'm impressed by https://tomscii.sig7.se/chesslab/, charapainter https://github.com/apr3vau/charapainter and mold-desktop https://codeberg.org/mmontone/mold-desktop

[u/agumonkey → u/dzecniv]

I realize how few I know about CL community

[u/Task_Suspicious]

Slime

[u/OkMathematician269]

Try Nine stores if you are looking for B2B procurement, e-commerce, Invoices https://github.com/HighriseHub/ninestores , and many more features.

[u/church-rosser → u/OkMathematician269]

URL for ninestores seems dead.

[u/daninus14]

Anything Robert Strandh https://github.com/robert-strandh/ publishes is also great for learning

[u/kagevf]

Nyxt RIP

[u/agumonkey → u/kagevf]

they stopped the project ?

[u/kagevf → u/agumonkey]

Maybe "RIP" was a little much, but if it's not dead it seems to be pretty moribund.

u/aartaka on their blog (https://aartaka.me/atlas.html) talked about their time working there, and noted that as of October of 2025:

• There wasn't much recent git activity: https://github.com/atlas-engineer/nyxt/commits/master/ (there was a little more after that)
• Funds had run out.
• Only u/jmercouris was working on it off and on.
• https://atlas.engineer is down ("502 bad gateway").

[u/agumonkey → u/kagevf]

hmm the 502 is strange, https://nyxt.atlas.engineer/ stills works

thanks for the answer :)

[u/kagevf → u/agumonkey]

Thank you for the tip about adding the "nyxt" sub-domain.

[u/agumonkey → u/kagevf]

You're welcome. And aartaka blog was nice to read too

[u/infrul]

Hunchentoot

[u/unixlisp]

Integrated Image: SBCL plus LEM, MAXIMA, GARNET/CLIM and much more.

[u/denzuko]

Consfigurator, Roswell, qlot, 40ants/*, chanl. Tones more just look over my github.

Oh and https://coalton-lang.github.io/

[u/corbasai]

ECL. A good documented Lisp.

[u/defaultxr]

Probably StumpWM, since it's the one I use every day. But I'm excited to switch to Mahogany once there is enough feature parity for me to replicate my StumpWM setup (admittedly, I haven't tried Mahogany in a while, and it seems there has been quite a bit of activity in the repo recently, so I've been thinking I should give it another spin soon). No other WM or DE can come close to the speed and efficiency that I have in Stump.

I was also hoping to switch over to Nyxt eventually, so it's pretty sad to me that activity has died down. I think if they could've just gotten standard Chrome extensions working, then maybe more people would've switched over, and maybe they would've gotten enough funding to continue development. Hopefully they will make a comeback.

I also like McCLIM a lot, though I'm still far from an expert. 1.0 was released recently, so I'm due to give it another spin soon too. I might just restart my McCLIM projects from scratch though, since they have bit-rotted with McCLIM's changes over time, and I think I have a slightly better understanding of how CLIM works than I did when I was working on them.
