Wow, wasn't expecting to see my post on here! Eventually, I want to write a follow-up, but I'm still a beginner. Here's what I've liked about Common Lisp so far: * The condition system is neat and I've never used anything like it -- you can easily control code from afar with restarts * REPL-driven programming is handy in situations where you don't quite know what will happen and don't want to lose context -- for exam…
I see a lot of “coding” talk in the blog and comments from the author here, but few mentions as to what kind of software they’re building or what use cases they’re targeting. My hot take is that the reason functional programming never took off is that, while it certainly is fine for writing programs, most software these days is not “program running locally on my pc/server from the command line until it completes” and…
Note that Common Lisp contains CLOS, which is one of the most advanced object-oriented systems even now. Most Lisps are not functional like Haskell is.
Yes, the article calls it powerful, but aside from the ability to update classes and their functions at runtime - which, maybe I’m missing the utility of so I won’t say it’s useless although in my experience a SharedInstanceSingleton or LocalImmutableConfig or BatchedMonitoringEvent wouldn’t need it - it’s “just” dynamically resolving the method implementation to use based on argument types dynamically and letting you provide an order of precedence for diamond inheritance.
I think it does solve one problem I have - with some solid tooling and a guarantee that class updates at runtime don’t disrupt ongoing calls, it might let me patch running binaries without doing a full update. Though, the cost is that I seem to incur a few extra lookups or even sorts on each dynamically dispatched method, to resolve the implementation? Besides that it doesn’t seem to really solve most problems I have regarding I/O or state - having the option to update some of these at runtime is interesting but it seems like something I’d only want to selectively enable

Quicklisp doesn’t use TLS or signatures? How have I not heard this before? That would be unbelievably irresponsible. Has this really not been addressed by the CL community? Edit: here’s the issue: https://github.com/quicklisp/quicklisp-client/issues/167 Thanks for bringing this up!
Try ocicl instead of quicklisp. System tarballs are hosted in an OCI registry, and are downloaded via TLS connections (obeying proxies). Tarballs are signed and signatures are stored in the sigstore rekor transparency log for later inspection. https://github.com/ocicl/ocicl

> The repl driven workflow is amazing and the lisp images are rock solid and highly performant. do people not realize that basically everything vm/interpreted language has a repl these days? https://www.digitalocean.com/community/tutorials/java-repl-j... https://github.com/waf/CSharpRepl https://pub.dev/packages/interactive not to mention ruby, python, php, lua hell even c++ has a janky repl https://github.com/root-p…
The repls you mention are not like lisp repls. You're being downvoted because your comment makes it sound like you've never programmed a lisp but have strong opinions nonetheless.
Maybe the ability to send expression from the IDE into the REPL with one keybind but I cannot say it's not possible with the Kotlin one right now because that's not what I use it for.

Love your site's CGA vibes.

Not the OP but would somebody be able to summarize HOW are the lisp REPLs different then to me? I've written limited amount of clojure and common lisp just to play around and I don't recall any difference between Clojure REPL and the REPL I get for say Kotlin inside IntelliJ idea. Maybe the ability to send expression from the IDE into the REPL with one keybind but I cannot say it's not possible with the Kotlin one ri…

This is all currently just a hobby. For Common Lisp specifically, the only things I've produced are a (mediocre) Battlesnake client and a (now defunct, as of yesterday) multiplayer word scramble game. Neither of these really derive…
Completely agree code generation is where I expect Lisp to perform the best. Though, I looked it up and apparently Markdown is not context-free so.. curious as to the challenges that introduces as I figure FP could zap through parsing a CFG but really struggle with state for something not context free

Can you connect to a running server or other running application, inspect live in memory data, change live in memory data, redefine functions and classes and have those changes take immediate effect without restarting the server or app? I think that is that is the big difference. It’s a triple edged sword bonded to a double barreled shotgun though, and the very antithesis of the idea of functional programming vs muta…
>Can you connect to a running server or other running application, inspect live in memory data, change live in memory data, redefine functions and classes and have those changes take immediate effect without restarting the server or app? The answer to all of these things, at least in python, is emphatically yes. I do this absolutely all the time. You can debug from one process to another if you've loaded the right ho…

SBCL supports static builds by saving core with runtime into an executable file you can then copy around at will.
Do they work across glibc verisons or musl libc? My understanding is that they do not.

Can you give me some links? I don’t program clojure much these days but I’ve never found anything comparable in python.
I need to be very clear so that no one misunderstands: this is not proprietary pycharm functionality - this is all due to to sys.settrace and the pydev debug protocol
https://www.pydev.org/manual_adv_remote_debugger.html
So you can hook this up completely by yourself with some work but lucky for you and me pycharm makes it effortless.
