00:15:35FromDiscord<anuke> `.nims` configuration files show spurious errors when opened with the official VSCode extension. This seems to happen with every Nim VSC extension, and across various configuration options. Is this a known issue? How do I fix this? https://media.discordapp.net/attachments/371759389889003532/1297352478689595403/Screenshot_from_2024-10-19_20-11-14.png?ex=67159d26&is=67144ba6&hm=53c59f0d6aec51e008a89dacb1fc703a6b03dcced7e5d0c3b5d7217c46a8412c&
00:21:49FromDiscord<anuke> <https://github.com/nim-lang/vscode-nim/issues/74#issue-2417720314> suggests that other people have experienced it as well, but it seems like too obvious of a problem for it to have only a single issue...
00:35:56FromDiscord<Robyn [She/Her]> In reply to @anuke "`.nims` configuration files show": at the top, you can do `when nimvm: import system/nimscript`
00:36:03FromDiscord<Robyn [She/Her]> bit of a hack but if it works, it works
00:44:10FromDiscord<anuke> sadly it does not https://media.discordapp.net/attachments/371759389889003532/1297359671580950558/image.png?ex=6715a3d9&is=67145259&hm=747929d8ede38e6c7615df8da510c7951b69d3f947da98197157b66f356b83dd&
00:44:20FromDiscord<anuke> importing it twice seems to lead to other errors
00:44:38FromDiscord<anuke> (it's not a spurious error this time, compilation fails as well)
01:01:52FromDiscord<Robyn [She/Her]> ah, sorry then

01:51:08FromDiscord<Elegantbeef> It's a bug
01:59:34FromDiscord<emanresu3> a bug in nim? is it already reported?
01:59:40FromDiscord<Elegantbeef> No clue
01:59:46FromDiscord<Elegantbeef> It's' a bug in Nim yes
02:00:08FromDiscord<Elegantbeef> `var T` where `T is ref` is causing an implicit dereference in Nim which is why it says `myclass:ObjectType`
02:01:20FromDiscord<emanresu3> I see, thanks beef, I'll use different field names for now then

07:01:41Amun-Rais that CD contain something required for connecting to verizon?
07:07:45FromDiscord<spaceshaman> What does it take to make nim build your whole website from dom to styles to behavior?
07:11:25FromDiscord<spaceshaman> I could see such a... 'model' being designed like a target type a-la library vs executable (in this case vs gui application)
07:18:33FromDiscord<spaceshaman> I guess some of the api needs of a web model aren't translatable to a gui app. Like the difference between a hyperlink that creates a new tab and one that recycles the current tab.
07:20:34FromDiscord<spaceshaman> So a gui app target is probably inadequate for a fully featured website target, though you would still want it to work as a js backend.

09:23:27FromDiscord<xtrayambak> In reply to @emanresu3 "any idea why this": I'm pretty sure you don't need the `var` suffix when dealing with ref'd objects

09:34:27FromDiscord<xtrayambak> sent a code paste, see https://play.nim-lang.org/#pasty=xKrNXpjH
09:34:34FromDiscord<nocturn9x> yeah I think so as well
09:34:43FromDiscord<xtrayambak> refs never play well with C structs
09:35:07FromDiscord<nocturn9x> I'll try var
09:35:10FromDiscord<xtrayambak> also, you should check out [weave](https://github.com/mratsim/weave) if you don't want to deal with the hassle of threading
09:35:15FromDiscord<xtrayambak> (edit) "threading" => "threads"
09:36:14FromDiscord<nocturn9x> all libraries I've tried to use either suck or fail to do some transformation to my code
09:36:19FromDiscord<nocturn9x> so I'll stick with raw channels lol
09:38:49FromDiscord<xtrayambak> refs are an absolute pain in the arse for me, I'm so glad that I can ditch them entirely now :)
09:39:03FromDiscord<xtrayambak> they have a tiiiiny bit more boilerplate, but it's absolutely worth it
09:43:51FromDiscord<fabric.input_output> I usually make my own `Arc[T]` and `Box[T]` types
09:56:14FromDiscord<nocturn9x> I just realized that channels do deep copies
09:56:17FromDiscord<nocturn9x> I need references :|

16:07:04FromDiscord<frusadev> Hi there!↵Is there a way to have absolute imports in nim? Instead of relative import?
16:07:15FromDiscord<frusadev> I'm using nimble btw
16:15:40FromDiscord<frusadev> sent a code paste, see https://play.nim-lang.org/#pasty=EzhuTfvk
16:21:08FromDiscord<frusadev> I think it makes code more readable that using relative paths
16:21:18FromDiscord<frusadev> (edit) "that using" => "thanusing"
16:21:27FromDiscord<frusadev> (edit) "thanusing" => "than using"
16:22:12FromDiscord<ieltan> In reply to @myxi "go vs nim benchmarks": Meaningless benchmark says nothing about which language is suited for your usecases. Nim is great all around while Go is definitely much better when you need concurrency
16:26:53FromDiscord<janakali> In reply to @frusadev "Hi there! Is there": add `--path:'.'` to `config.nims` in your project's root directory and now you can use absolute paths like this `import src/pkgexample/file1`
16:27:29FromDiscord<frusadev> In reply to @janakali "add `--path:'.'` to `config.nims`": Thx!
16:28:35FromDiscord<frusadev> Even if i'm using nimble?
16:31:07FromDiscord<janakali> nimble makes use of config.nims file too
16:32:09FromDiscord<janakali> @frusadev sorry, correct syntax is with double quotes: `--path:"."`
16:35:50strogon14or use e.g. 'switch("path", "$projectDir/../src")'
16:38:46FromDiscord<frusadev> In reply to @strogon14 "or use e.g. 'switch("path",": 🤔 this syntax even seems to work with nimls! i assume --path would only work with the compiler.
16:38:51FromDiscord<frusadev> Thanks!
16:39:34strogon14-- is just a template for "switch" defined for NimScript

19:21:50FergusLoops, installing nim with my package manager instead of choosenim somehow fixed this, sorry for the noise!

19:24:17Amun-Raevery ontopic noise counts :)
19:32:54*lumidify joined #nim
20:05:52FromDiscord<odexine> What are we counting
20:22:22FromDiscord<Elegantbeef> All real numbers
20:27:06FromDiscord<nervecenter> In reply to @myxi "go vs nim benchmarks": Tends to be the case that Nim is faster in most cases than Go, except with concurrency like people have said. Go's GC also doesnt handle a lot of pressure very well and I'm pretty sure Nim's RC variants are all leaner and faster.
20:28:20FromDiscord<Elegantbeef> Not to mention that the vercel benchmarks are a joke
20:29:51FromDiscord<Elegantbeef> https://github.com/hanabi1224/Programming-Language-Benchmarks/blob/main/bench/algorithm/spectral-norm/1.nim vs. https://github.com/hanabi1224/Programming-Language-Benchmarks/blob/main/bench/algorithm/spectral-norm/8-m.rs
20:30:01FromDiscord<Elegantbeef> Notice one of these uses `simd`, but that surely does not matter 😄
20:31:55FromDiscord<nervecenter> Yeah I was gonna say the Rust one is using an auto-parallelism library along with SIMD
20:32:00FromDiscord<nervecenter> Nim one is just using sstdlib lel
20:32:08FromDiscord<nervecenter> (edit) "sstdlib" => "stdlib"
20:32:14FromDiscord<Elegantbeef> If the implementations are not the same, I hardly see the point
20:34:34FromDiscord<Elegantbeef> Yea it's like racing horse that was given a bunch of stimulants vs. a non domesticated horse
20:34:38FromDiscord<nervecenter> Would the equivalent functionality here all be in Arraymancer?
20:35:41FromDiscord<Elegantbeef> For the example I gave?
20:35:55FromDiscord<Elegantbeef> Using simd ops is all it takes for what I gave
20:37:56FromDiscord<nervecenter> No experience on that front so I'm clueless as to what that means. Maybe I should start digging into it, the product I make could probably benefit.
20:38:12FromDiscord<nervecenter> (edit) "means." => "means on a practical level."
20:39:01FromDiscord<nervecenter> Though my gnarliest worst-case scenario takes less than a real-world minute to run server-side.
20:39:18FromDiscord<Elegantbeef> Simd uses larger registers and uses a single cycle to do multiple operations on data at once
20:39:24FromDiscord<Elegantbeef> It's like a hardware supported multithreaded operation for a single operation type
20:40:12FromDiscord<Elegantbeef> Like you have 256bit registers and can do addition for 8 float32s at once
20:40:37FromDiscord<Elegantbeef> In many cases you can save cycles if you load all your data in a big buffer and do a single operation at once
20:40:40FromDiscord<nervecenter> I know those basics, and that the x86 instructions all have `mm` labels or some such, but trying to read SIMD code gives me a headache.
20:41:12FromDiscord<Elegantbeef> Hell you can simd string find if you really wanted to to make it faster 😄
20:41:24FromDiscord<Elegantbeef> Eh the operations are fairly simple so it's not too hard if you just refer to the documentation
20:41:25FromDiscord<nervecenter> Oh crap I did not know that
20:42:01FromDiscord<Elegantbeef> See which operations are used then think about it on a atomic level
20:42:30FromDiscord<Elegantbeef> by atomic I mean per each element in the buffer
