9:27:27 clintm If I have two structs both with a slot of the same name, and I call the slot accessor function from one on an instance of the other, that's supposed to be a type error, right? If so, does allegro really just return nil?

9:28:31 beach Why would it be a type error?

9:28:47 clintm I tested it in a bare alisp repl, but I'd like cofirmation before I plant a proverbial flag in the sand and say "this is bad and we shouldn't do it" at work.

9:29:56 flip214 clintm: for classes there's the generic function and methods framework. for structures the structure name is prepended for accessor names to avoid such conflicts.

9:32:57 clintm beach: because it's two different types, at least that's what I assumed. (defstruct a id) (defstruct b id) (a-id (make-b)) -> nil. Should that really be nil? On LW it's a type error.

9:33:02 beach Oh, type error because you are giving it a struct of a different type. Got it.

9:33:10 clintm I mean, I assumed it would be a type error.

9:33:22 beach It might just be undefined behavior.

9:33:54 lieven is safety at the highest setting?

9:34:01 beach Structs are designed to be fast. It wouldn't surprise me if the accessor does nothing other than access an element with a particular index.

9:34:10 clintm lieven: Oh, I didn't try that.

9:36:48 clintm Same :(

9:37:10 beach Structs are weird. I strongly suggest you use standard classes instead.

9:37:10 clintm At least with debug and safety 3

9:37:57 flip214 clintm: on SBCL I get The value #S(B :ID NIL) is not of type COMMON-LISP-USER::A

9:38:11 lieven an implementation is certainly allowed to carp but I don't think it's required

9:38:22 clintm flip214: That's what I got with LW as well.

9:39:08 clintm Hrm, maybe if I scour the allegro docs I can find a way to turn it on even if just during testing and development. Thanks for the info, everyone!

10:00:30 Harag is there a "prefered" "portable" pretty printing library out there that deals with writing the likes of clos objects and hashtables as readable, even if it is just readable by itself

10:01:39 phoe I have phoe-toolbox:print-hash-table-readably for hash tables

10:02:26 phoe and also possibly phoe-toolbox:print-instance-readably that tries to be DWIMmy in what it does

10:02:37 phoe and therefore can miserably fail if one doesn't know what they're doing

10:03:07 phoe see https://github.com/phoe/phoe-toolbox/blob/master/phoe-toolbox.lisp#L434

10:03:48 Harag phoe: I have some as well was just wondering if I was reinventing the wheel again...

10:05:05 flip214 Harag: alexandria has (hash-table-alist) and -plist and the reverse functions... but you loose the :test that way.

10:05:45 edgar-rft (print-readaby "btbtfdctgzthqmjbycftrwknrngmcjvbtnbwlkvf" :-)

10:15:45 phoe Harag: reinventing the wheel is common in places where the standard and Alexandria are lacking

10:19:54 kongmar ** NICK margeas

10:20:06 margeas ** NICK markoong

10:30:24 flip214 phoe: perhaps such wheels should be added to alexandria-2, then

10:36:33 Lord_of_Life_ ** NICK Lord_of_Life

10:40:27 phoe flip214: tempting

10:50:15 flip214 phoe: can only save space if there are less duplicated implementations of common things

12:29:18 rgherdt_ ** NICK rgherdt

13:36:19 phoe flip214: I don't know what should A² be composed of; I could think a little bit on it and propose some ideas

13:40:59 Xach Would you please try to "curl https://beta.quicklisp.org/quicklisp.lisp > /dev/null" and tell me if you get an error from curl?

13:42:46 Bike is that an open question? i didn't see any errors.

13:42:58 Xach So open

13:43:52 Xach Bike: do you mind telling me what OS you are using?

13:44:02 Bike arch linux. i can try it on a mac too if you want.

13:44:12 Xach Bike: if you don't mind, please do

13:44:44 Bike (60) SSL certificate problem: certificate has expired

13:44:57 Xach Thanks.

13:45:34 Bike welcome

13:45:50 Xach Different client SSL configurations produce different results. It's frustrating.

13:46:46 phoe Bike: which mac version?

13:47:04 Xach phoe: I get it on 10.15.5

13:47:41 phoe that's surprisingly recent

13:47:42 phoe hmmm

13:47:54 Bike uh, 10.13 i think.

13:48:42 Bike and i think i got curl through homebrew?

13:50:46 Xach Hmm, I think I see what I might be able to do.

13:51:50 ArthurStrong Hi all!

13:52:16 phoe heyy ArthurStrong

13:52:35 vegai glad to see the vscode plugins + lsp working pretty well already

13:52:51 vegai I've used emacs for a long time so going back to that would be possible

13:52:57 vegai I'd rather not though, if there was any options :)

13:53:48 phoe vegai: could you give me some sort of screenshots? is the REPL and incremental compilation working?

13:58:31 vegai REPL and incremental compilation are working, yes

13:58:57 Xach Bike: could you please try again?

13:59:14 Bike works this time. on both systems.

14:00:11 phoe vegai: :O

14:00:20 phoe do you have some sort of screenshots and/or videos?

14:00:58 Xach Bike: thank you very much

14:01:12 Bike no problem

14:01:28 vegai phoe: didn't this use to work? No, I don't readily have screenshots or videos

14:01:39 Xach I need to compress my systems.txt and releases.txt. They are by far the biggest traffic generators for dists.

14:01:45 Xach way more than actual archives.

14:01:55 vegai this certainly isn't as advanced as SLIME is

14:01:59 phoe vegai: I don't know - I never watched the CL-on-VSCode scene

14:02:04 phoe perhaps I should

14:02:08 vegai but is enough to get started

14:02:12 X-Scale` ** NICK X-Scale

14:02:51 beach I wonder whether that is scymtym's work.

14:03:15 beach I know he worked on it but maybe someone else did as well.

14:12:55 X-Scale` ** NICK X-Scale

14:19:16 flip214 Xach: the root certificate says valid until "18. Januar 2038, 23:59:59 GMT", perhaps that's a 31bit problem?

14:25:10 phoe flip214: we'll worry about that in December 2037

14:26:48 flip214 phoe: no, because the certificate isn't accepted _now_

14:28:01 phoe wait a second...

14:28:10 phoe that's the end date

14:28:13 phoe what's the start date?

14:28:55 flip214 Xach: brotli is modern

14:29:20 flip214 phoe: May 2019

14:29:58 phoe the dates seem okay then

14:31:17 flip214 yeah, but the arithmetic on them might be broken

14:37:49 phoe huh, 18th Jan should still fit within Y2K38

14:38:30 Xach flip214: oh, i would just stick with gzip, since i already have the code for it in the client.
