00:12:06FromDiscord<j-james> In reply to @j-james "i think the problem": turns out this does actually cause a problem - as `result != return T`
00:13:04FromDiscord<j-james> so i've got a bunch of useless structures as the layouts' parents instead of a pointer to the returned type
01:21:52*CyberTailor joined #nim
02:46:28FromDiscord<valerga> does breaking inside a block, which is inside a for, not break the for?
02:47:15FromDiscord<j-james> it should not
02:47:57FromDiscord<valerga> so it breaks what, the block?
02:48:11FromDiscord<j-james> yeah
02:48:14FromDiscord<valerga> using continue works as expected though so idk
02:48:30FromDiscord<j-james> if you want to break out of both the block and the for loop, you can use a named block
02:48:38FromDiscord<valerga> that's what i do yeah
02:50:19FromDiscord<j-james> sent a code paste, see https://play.nim-lang.org/#ix=41p0
02:50:50FromDiscord<valerga> so inside the block, "break", and "continue", do the same?
02:50:50*CyberTailor quit (Remote host closed the connection)
02:51:25FromDiscord<valerga> without using the name
02:52:00FromDiscord<j-james> break and continue should refer to the current scope
02:52:18FromDiscord<valerga> ok yeah. i mean on outer scrope
02:52:20FromDiscord<valerga> (edit) "scrope" => "scope"
02:52:25FromDiscord<valerga> inside the block
02:53:46FromDiscord<j-james> oh inside `block name` but outside the for loop and the second block?
02:53:49FromDiscord<j-james> yes
02:54:34*CyberTailor joined #nim
02:56:30FromDiscord<j-james> yeah you don't _need_ to name named blocks in break statements
03:02:05FromDiscord<j-james> In reply to @valerga "using continue works as": oh yeah - continue statements aren't effected by blocks
03:02:22FromDiscord<j-james> /s/effected/affected
03:02:45FromDiscord<j-james> (edit) "effected" => "affected"
03:03:09FromDiscord<j-james> they'll just immediately skip to the next iteration
03:08:23FromDiscord<Elegantbeef> Continue is only effected by continuable control
03:08:26FromDiscord<Elegantbeef> So `for` and `while`
03:10:36FromDiscord<!Patitotective> hey guys i was thinking on making a twitter bot that retweets & likes any tweet with the #nimlang hashtag or containing "nimlang"↵how else do you guys think i should filter the tweets? i was thinking of only in english and maybe exclude tweets including the word malware lol
03:11:00FromDiscord<Elegantbeef> This is indeed a society
03:11:46FromDiscord<Prestige> I hate twitter
03:12:12FromDiscord<Elegantbeef> Well we're not answering their question with our critique 😛
03:12:36FromDiscord<Elegantbeef> Sounds fine to filter the way you're doign
03:12:59FromDiscord<Prestige> I think he should filter out all the tweets, then work on literally anything else
03:13:25FromDiscord<!Patitotective> :[
03:13:46FromDiscord<Elegantbeef> Though this gives me an idea a social media platform where traffic is done by bots but content is human generated
03:13:48FromDiscord<Elegantbeef> We can call it insert your least favourite social media platform here
03:14:19FromDiscord<!Patitotective> In reply to @Elegantbeef "Though this gives me": that sounds like youtube but well made
03:14:46madpropswondering if any of you have as an example of a simple nim program published in the arch's aur ?
03:15:04FromDiscord<Elegantbeef> Is nimdow there?
03:15:06FromDiscord<Elegantbeef> I dont recall
03:15:22madpropshttps://archlinux.org/packages
03:15:27madpropsoh wait
03:15:36madpropshttps://aur.archlinux.org/packages
03:16:11madpropsit should depend on the nim compiler. then just fetch from github, and compile
03:16:18madpropsim looking for an example pkgbuild
03:16:25FromDiscord<Elegantbeef> There you go now hit prestige to give you answers
03:16:30FromDiscord<Prestige> Yes nimdow-bin is in the aur
03:16:48FromDiscord<Prestige> I just have it upload the pre-compiled binary though
03:17:04FromDiscord<Elegantbeef> Not very archy
03:17:06FromDiscord<Prestige> Cuz I couldn't figure out how to pull in Nim so I could compile nimdow
03:17:28FromDiscord<Prestige> Cuz nim was super outdated and we couldn't pull down choosenim etc
03:17:42FromDiscord<Elegantbeef> Well it's modern now iirc
03:17:54FromDiscord<ripluke> In reply to @Elegantbeef "Not very archy": What does that mean
03:18:09FromDiscord<Elegantbeef> Does what i say ever really have meaning
03:18:31FromDiscord<!Patitotective> ive already said this, hes high
03:18:47FromDiscord<ripluke> In reply to @Avahe "Cuz I couldn't figure": It's 1.4.8
03:18:53FromDiscord<Prestige> @ripluke do you have any PKGBUILD experience?
03:18:59FromDiscord<ripluke> Yes lol
03:19:07FromDiscord<Elegantbeef> I'm never high, i thought that arch had a reputation for easily enabling compilation from source
03:19:07FromDiscord<ripluke> I literally only package for arch
03:19:20FromDiscord<Prestige> nim is 1.6.6 in community/nim
03:19:26FromDiscord<Prestige> So you should be good
03:19:46FromDiscord<ripluke> They updated it then
03:20:11FromDiscord<Prestige> yeah pretty recently
03:21:10FromDiscord<Prestige> oh it was madprops that was asking, mb
03:21:37madpropsyeah im reading the guidelines
03:21:40madpropsdon't want to mess up
03:21:45FromDiscord<Prestige> https://wiki.archlinux.org/title/Creating_packages#PKGBUILD_functions
03:21:59FromDiscord<Prestige> and check out other PKGBUILDs with build steps
03:22:17FromDiscord<ripluke> Funny thing I actually figured out how to write pkgbuilds from reading the nimdow pkgbuild
03:23:27FromDiscord<Prestige> Heh, that's cool
03:23:35FromDiscord<ripluke> Lol yea
03:25:31FromDiscord<Prestige> If I land this new job, I'll have to start using Ubuntu for work. So I'll likely be packaging it for Ubuntu then
03:25:43FromDiscord<ripluke> Oh
03:25:56FromDiscord<Elegantbeef> Sorry for your loss 😄
03:25:58FromDiscord<Elegantbeef> snapd WM when?
03:26:05FromDiscord<ripluke> Lol I have to write a pkgbuild now for an aur now
03:26:15FromDiscord<ripluke> In reply to @Elegantbeef "snapd WM when?": 😳😳
03:26:28FromDiscord<ripluke> I'd use it 💀
03:26:38FromDiscord<!Patitotective> In reply to @Elegantbeef "Sorry for your loss": 😄
03:26:46FromDiscord<ripluke> (edit) "use" => "~~use~~ try"
03:30:13FromDiscord<Prestige> In reply to @Elegantbeef "Sorry for your loss": Yeah, at least it's Linux though
03:30:42FromDiscord<Prestige> If it's not managed like crazy I could transform it into whatever I'd like
03:31:10FromDiscord<Elegantbeef> at that point just use debian and play it off 😛
03:34:01FromDiscord<Prestige> Eh has to be some specific ubuntu lts version unfortunately
03:36:21madpropsripluke you have an example of a pkgbuild that pulls from github and compiles with the nim compiler?
03:37:10madpropsthis is a simple program though, doesn't even have 3rd party libs
03:37:22madpropsonly depends on the compiler
03:37:54FromDiscord<ripluke> Yup

03:40:11FromDiscord<ripluke> sent a code paste, see https://play.nim-lang.org/#ix=41p4
03:40:57FromDiscord<Prestige> I thought you're not supposed to use sudo for install here
03:41:14FromDiscord<ripluke> idk it didnt work without it
03:41:25madpropsare you installing to /usr/local/bin?
03:41:25FromDiscord<ripluke> so i just put it there
03:41:29FromDiscord<ripluke> yea
03:41:30FromDiscord<Prestige> Gotta do like `install -D "nimdow-$pkgver" "$pkgdir/usr/bin/nimdow"`

03:42:27FromDiscord<ripluke> it gets the job done tho
03:44:48FromDiscord<!Patitotective> also guys, what do you think is the best way to host the twitter bot? running it with a cron task locally? heroku?
03:47:09FromDiscord<ripluke> Nvim is fun
03:47:14FromDiscord<ripluke> Super fun
03:47:19FromDiscord<Prestige> I love neovim
03:47:31FromDiscord<ripluke> Yea but it has quirks
03:47:33FromDiscord<Prestige> In reply to @Patitotective "also guys, what do": How do you want it to run, periodically?
03:47:47*noeontheend joined #nim
03:47:51FromDiscord<!Patitotective> yea
03:47:57FromDiscord<ripluke> In reply to @ripluke "Yea but it has": Like pasting with "p" always puts it in the wrong spot
03:48:11FromDiscord<Prestige> Huh? It works perfectly for me
03:48:48FromDiscord<ripluke> Idk sometimes when I want to paste something inside a string, it puts it outside of the quotes
03:49:00FromDiscord<!Patitotective> In reply to @Patitotective "also guys, what do": actually github actions might work :o
03:49:08FromDiscord<ripluke> In reply to @Patitotective "actually github actions might": Ya
03:49:16FromDiscord<Prestige> Depends if you yanked a newline at the end, or if your cursor is inside the quotes
03:49:24FromDiscord<Prestige> but it works consistently and how it's intended to work
03:50:00FromDiscord<ripluke> In reply to @Avahe "Depends if you yanked": Yea but with shift+v then yanking it does that
03:50:24FromDiscord<Prestige> That yanks the newline at the end of the line
03:50:36FromDiscord<Prestige> and `p` pastes _after_ the current character
03:51:08FromDiscord<Prestige> maybe you want `yg_` then you can `p`
03:51:32FromDiscord<Prestige> or `0yg_`
03:51:48FromDiscord<ripluke> In reply to @Avahe "maybe you want `yg_`": I'll try that
04:01:36FromDiscord<Rika> Shift P?
04:03:12madpropsshould i make the arch x86_64 or any for the pkgbuild if nim is compiling it?
04:07:31madpropsim guessing nim can compile to anything
04:10:39FromDiscord<Prestige> In reply to @Rika "Shift P?": That'd put it on the previous line if he's yanked a whole line

09:49:25madpropswhat's faster than strutils.contains ?
09:51:25FromDiscord<Rika> What’s your exact use case, there might be a better way than naive string operations
09:51:37madpropsi want to check if a substring exists in a line of text
09:51:52madpropsin a case insensitive manner. currently i toLower it
09:52:10madpropsbut that the bottleneck is at contains
09:53:42madpropsim gonna try re.contains
09:54:17FromDiscord<Rika> Regex is possibly slower
09:54:34FromDiscord<Rika> Might not be depending on optimisations but it’s prolly going to be slower
09:57:11madpropshmm how can i build this
09:57:14madpropslet regexp = re(&"/{q}/")
09:57:21madpropstrying to use the variable (q)
10:00:47madpropsre(q) works in my case
10:01:12madpropsbut speed is basically the same
10:01:57madpropsim trying to beat "ag" in speed but something funny happens
10:02:05madpropsit alternates between 6ms and 16ms in time
10:02:12madpropsit's not consistent (ag)
10:02:28madpropsmy implementation is at around 14ms but consistent
10:04:49madpropsbut ag is still faster overall when i try whole directories
10:05:09madpropsit probably cheats in some way
10:11:27madpropsah interesting. like 10ms from the 16ms are spent making it toLower
10:23:47FromDiscord<phargob> alloc() documentation suggests a separate heap per thread. with ARC/ORC is this valid anymore? isnt there one shared heap?
10:29:42FromDiscord<vindaar> are you using `toLower` for unicode runes or for regular chars? the former is likely pretty slow. the latter should be pretty quick (just shifting based on `ord`)↵(<@709044657232936960_madprops=5b=49=52=43=5d>)
10:29:50FromDiscord<Rika> How are you profiling your application
11:24:03FromDiscord<enthus1ast> ag is the\_silver\_searcher right?
11:24:13FromDiscord<enthus1ast> they also use pcre ↵#include \<pcre.h\>
11:43:34FromDiscord<Phil> sent a code paste, see https://play.nim-lang.org/#ix=41qf
11:46:34FromDiscord<Yardanico> I have a similar proc in my Nim eventer , lemme see if it's better
11:47:08FromDiscord<Phil> I have a playground project with benchy etc. already set up, if you can throw in the proc I can copy paste it in quickly for a comparison
11:47:33FromDiscord<Yardanico> it's a bit different as it does that by words
11:47:38FromDiscord<Yardanico> But there's an idea to make your proc faster
11:48:01FromDiscord<Yardanico> iterate on split (there's an iterator version of it) and increment untill you get 40 words
11:48:05FromDiscord<Yardanico> then just break
11:49:04FromDiscord<Yardanico> rugby now you split, then slice and then join again
11:49:38FromDiscord<Yardanico> I'm not a home so I can't write a complete proc, maybe in the evening

11:53:28FromDiscord<Yardanico> how are you benchmarking?
11:54:10FromDiscord<Phil> sent a code paste, see https://play.nim-lang.org/#ix=41qi
11:54:13FromDiscord<Yardanico> this doesn't keep the result string
11:54:24FromDiscord<Yardanico> Add `keep str` to all blocks

11:56:22FromDiscord<Yardanico> sent a code paste, see https://play.nim-lang.org/#ix=41qk
11:56:31FromDiscord<Yardanico> you don't need the splitString, as I said, use split as an iterator
11:56:43FromDiscord<Phil> Ohhh that's what you meant, alrighty, let me see
11:57:20FromDiscord<Yardanico> https://nim-lang.org/docs/strutils.html#split.i%2Cstring%2Cchar%2Cint
11:57:32FromDiscord<Yardanico> Also you don't need to concat like that
11:58:19FromDiscord<Yardanico> " " & str
12:00:11FromDiscord<Phil> Holy shit
12:00:30FromDiscord<Phil> Okay, yeah that's a significantly better approach, and I haven't even done anything to the concat yeah
12:00:58FromDiscord<Phil> sent a code paste, see https://play.nim-lang.org/#ix=41qn
12:02:02FromDiscord<Yardanico> sent a code paste, see https://play.nim-lang.org/#ix=41qo
12:03:02FromDiscord<Yardanico> you can make it add word first and space later, then you can remove setLen but you'll have a leading space
12:04:07FromDiscord<Phil> Given that I'll be adding "..." to indicate there's more text either way, I think I can save myself the hassle of even doing that
12:04:54FromDiscord<Yardanico> yeah although this approach makes it impossible to not add ... if you put in the whole string
12:05:06FromDiscord<Yardanico> you can make it possible with parseutils, but it'll be a bit more low level

12:19:13*FromDiscord joined #nim
12:20:09FromDiscord<Yardanico> yes, but it depends on what input you feed to them
12:20:27FromDiscord<Yardanico> the preallocated memory one will be more performant for longer strings with longer words
12:23:31FromDiscord<enthus1ast> this is the truncate in nimjautils\: https://github.com/enthus1ast/nimja/blob/620aceecd91a9c34b408755e5a50ce6218cc33a7/src/nimja/nimjautils.nim#L113
12:24:09FromDiscord<enthus1ast> idk how well it performs
12:24:31FromDiscord<Yardanico> it keeps the whole string split in memory
12:24:48FromDiscord<Phil> sent a code paste, see https://paste.rs/UIN
12:26:57FromDiscord<Phil> In reply to @enthus1ast "this is the truncate": Hmmm you truncate by characters, rather than words
12:27:10FromDiscord<Yardanico> I do too in nimeventer
12:27:17FromDiscord<Yardanico> But I check if it's the word boundary
12:28:08FromDiscord<Yardanico> So I split by words but max context length is in chars
12:28:11FromDiscord<enthus1ast> do you want to truncate by words?
12:28:18FromDiscord<Yardanico> that way you can control resulting length of the string better
12:28:23FromDiscord<Yardanico> I think it makes more sense
12:28:42FromDiscord<Yardanico> Unless you're doing unicode, then doing that is not so simple
12:29:06FromDiscord<Phil> In reply to @enthus1ast "do you want to": I originally wanted to in order to avoid having cut-off words and thought doing it by word was simpler than doing it by char overall
12:29:35FromDiscord<Phil> Due to the complexity added by checking for "am I in the middle of a word, if not add more chars/remove chars until I am not"
12:30:02FromDiscord<Yardanico> There's no complexity
12:30:04FromDiscord<Phil> Which I found not-so-nice to have for a first naive implementation

12:31:08FromDiscord<Yardanico> postWords can be str.split(' ')
12:31:42FromDiscord<Yardanico> although after that I join the words from res seq, you can add words inline like you do already
12:32:33FromDiscord<Yardanico> So you still split by words, but you have precise control over max context string length
12:35:33FromDiscord<Phil> sent a code paste, see https://play.nim-lang.org/#ix=41qw
12:36:13FromDiscord<Phil> Just an FYI since I thought you might find it interesting
12:37:32FromDiscord<Phil> From what I've seen, performance wise `splitWhitespace.pairs()` is really hurting
12:37:42FromDiscord<enthus1ast> yeah, some perfomance potential still there
12:37:44FromDiscord<Phil> (edit) "hurting" => "hurting, compared to having var i = 0"
12:38:02FromDiscord<enthus1ast> ill fiddle with it a little
12:38:26FromDiscord<Yardanico> Yeah you can just use std/enumerate instead
12:38:27FromDiscord<Phil> I think I should do a lot more optimizations. Not that they're insanely useful for me, but you can learn quite a bit
12:38:36FromDiscord<Yardanico> there's a splitWhitespace iterator iirc
12:38:37FromDiscord<Phil> It's fun!
12:38:41FromDiscord<Yardanico> And enumerate adds indexes
12:38:46FromDiscord<Yardanico> to iterators
12:40:39FromDiscord<enthus1ast> sent a code paste, see https://play.nim-lang.org/#ix=41qx
12:40:41FromDiscord<enthus1ast> indeed wow
12:40:57FromDiscord<Phil> Yeah, similar results here

12:44:43FromDiscord<Phil> sent a code paste, see https://play.nim-lang.org/#ix=41qB
12:45:11FromDiscord<Yardanico> enumerate is the same as manual indexing
12:45:13FromDiscord<Phil> I guess it gets compiled into similar assembly in the end
12:45:15FromDiscord<Phil> Check
12:45:20FromDiscord<enthus1ast> thinks its quite the same
12:45:34FromDiscord<Phil> I'll definitely keep enumerate in mind more
12:46:13FromDiscord<Yardanico> I mean it's just sugar over manually declaring a variable and inc'ing it
12:46:37FromDiscord<Phil> I like sugar, I'll use that sugar
12:47:10FromDiscord<enthus1ast> wonder if we can teach the pairs() or the normal looping these tricks as well
12:47:31FromDiscord<enthus1ast> would be nice if the simplest is also the fastest
12:48:55FromDiscord<Yardanico> but the problem is that you call pairs on the non-iterator version
12:49:01FromDiscord<enthus1ast> yes
12:49:04FromDiscord<Yardanico> You can't really compose non-closure iterators
12:49:47FromDiscord<enthus1ast> did you not have these lib (zero functional?)↵(@Yardanico)
12:50:46FromDiscord<enthus1ast> ah no, but stuff like this would be nice

12:56:21FromDiscord<enthus1ast> min time is not always lower, but avg is always
12:56:43FromDiscord<Phil> it also seems to fluctuate less if the std dv is semi stable
12:56:48FromDiscord<enthus1ast> yes
12:57:05FromDiscord<Phil> I guess because less allocations mean less chance of having to wait for the system or sth?
12:57:20FromDiscord<enthus1ast> yes i also think so

15:12:50FromDiscord<xflywind> I checked with `koch temp`. It seems to be a benchy/Nim bug => .nimble\pkgs\benchy-0.0.1\benchy.nim(109)

15:15:41FromDiscord<xflywind> `template dots(n: Natural): string =` requires `Natural`, but the pass parameters `dots(40 - tag.len - m.len)` is somehow equal to `-4`.
15:16:02FromDiscord<xflywind> https://github.com/treeform/benchy/blob/848dc851559d48b60bd368fddb2761414daa8c3c/src/benchy.nim#L109
15:18:40FromDiscord<Yardanico> but it's a template
15:19:00FromDiscord<Yardanico> I don't think Natural would affect anything for a template
15:19:18FromDiscord<Yardanico> it should be a proc so Natural can actually check the range of the int
15:19:24FromDiscord<xflywind> Change 40 to 60 works.
15:19:36FromDiscord<xflywind> (edit) "Change 40 to 60 ... works." added "and then it"
15:20:51FromDiscord<xflywind> In reply to @Yardanico "I don't think Natural": Yeah, it calls `repeat` internally => `func repeat(c: char, count: Natural)`
15:23:34FromDiscord<xflywind> For a naive solution, I thin it should change `40` to a variable adjusting itself relative to `tag.len + m.len` in case that they are too large.
15:24:17FromDiscord<xflywind> In reply to @Isofruit "The proc itself even": In this case I think benchy cannoyt handle a tag name which is as long as `truncate_breakfor_enumerate_memoryalloc`.
15:24:23FromDiscord<xflywind> (edit) "cannoyt" => "cannot"
15:24:35FromDiscord<Phil> The length of the tag name is the issue? Fascinating

18:49:56FromDiscord<Phil> Of sorts. I'm really not the best person to ask, I'm personally not a massive fan of using `;` for separating proc params because it's a "non-standard" thing to me. But I also don't use `using` so...eh

18:50:59FromDiscord<Phil> (edit) ""have" => ""just have"
19:09:02reversem3[m]So you use only , "commas" for your proc parameters?
19:13:49FromDiscord<Phil> pretty much

19:17:10reversem3[m]ok , thanks
19:21:29FromDiscord<Rika> Not really
19:21:47FromDiscord<Rika> If you don’t use using you don’t really have a reason to use semicolon other than preference
19:38:46FromDiscord<dom96> there is no differences between the comma and semicolon as far as I know
19:39:24FromDiscord<dom96> they are only there to allow more clearly to separate generic types in param lists
19:39:36FromDiscord<dom96> I also don't use them
19:49:47reversem3[m]dom96: what don't you use? semicolon , or colon?
19:50:43FromDiscord<dom96> semicolon
19:51:58FromDiscord<Yardanico> In reply to @dom96 "there is no differences": there are differences, but they only appear when you use `using|

19:54:43FromDiscord<enthus1ast> This becomes relevant in generics
19:55:21reversem3[m]he's referring to `proc(x, y: int, s: string) to `proc(x, y: int, s: string)` comma compared to semi-colon for proc parameters
19:55:35FromDiscord<enthus1ast> Foo[A; B\: string\|int]
19:55:48FromDiscord<Yardanico> yes, this is a more common case than using actually

19:57:29reversem3[m]s/Expect/Except/
19:57:44FromDiscord<Yardanico> yes, in most cases the difference isn't visible, but the main thing is - , and ; ARE different

20:02:54reversem3[m]umm , now I'm confused
20:03:07reversem3[m]can you post that in a proc ?
20:04:22FromDiscord<Yardanico> proc test[A; B: SomeNumber](a: A, b: B)
20:04:33FromDiscord<Yardanico> in this case A will just be a generic for any type
20:04:43FromDiscord<Yardanico> While B is restricted for types from SomeNumber

23:36:18FromDiscord<Elegantbeef> Oh i misread
23:36:36FromDiscord<Generic> sent a code paste, see https://play.nim-lang.org/#ix=41tf
23:36:38FromDiscord<Generic> tada, I think this'll do

23:37:49FromDiscord<Generic> In reply to @voidwalker "why does adding entries": because adding data to a table is a fundametally more complex operation
23:38:33FromDiscord<voidwalker> Searching string in the table values is also 2x or 3x slower
23:38:37FromDiscord<Elegantbeef> Tables are hashed
23:38:53FromDiscord<Elegantbeef> Also are you testing in release or debug?
23:38:59FromDiscord<voidwalker> in danger
23:39:11FromDiscord<Generic> In reply to @voidwalker "Searching string in the": searching as in iterating over it or using it's proper access functions?
23:39:33FromDiscord<voidwalker> @Generic iterating over all values to search for a substring
23:40:05FromDiscord<Generic> I think you should make yourself familiar with some basic knowledge on data structures
23:40:20NimEventerNew thread by Matthesoundman: How to let nim know to search an additional path for linking a lib?, see https://forum.nim-lang.org/t/9278
23:40:25FromDiscord<Generic> the data lies sparsely in a table
23:40:56FromDiscord<Generic> in a seq all values lies contigously in memory, accessing one by one is trivial
23:41:12FromDiscord<Generic> in a table it has to check every entry first to see if there even lies a value
23:42:22FromDiscord<Yardanico> huh?
23:42:25FromDiscord<Yardanico> there are hashes
23:42:40FromDiscord<Generic> hashes don't help you when iterating over the table

23:46:20FromDiscord<retkid> no need for that we have math
23:46:24reversem3[m]Type inference doesn't work for object construction , that's why.
23:47:19FromDiscord<Generic> sent a code paste, see https://play.nim-lang.org/#ix=41tj
23:47:25FromDiscord<retkid> good enough
23:47:36FromDiscord<Generic> not when O(n) is possible 😛
23:48:14FromDiscord<retkid> the largest the array will get is like 64
23:48:24FromDiscord<Elegantbeef> Or reversem you were asking why you had to specify its generic parameters?
23:48:29FromDiscord<Elegantbeef> oh reversem\
23:48:55FromDiscord<retkid> sent a code paste, see https://play.nim-lang.org/#ix=41tl
23:49:01FromDiscord<retkid> its chunked and it just slices the last element
23:49:15FromDiscord<Elegantbeef> Two maps and a slice
23:49:28FromDiscord<Elegantbeef> Damn buh bye heap allocations 😄
23:49:49FromDiscord<Generic> also string conversion :puke:
23:49:59FromDiscord<Elegantbeef> yea what're you even doing
23:49:59FromDiscord<retkid> In reply to @Generic "also string conversion :puke:": what other option do i have
23:50:11FromDiscord<retkid> I've shown too much I'm being questioned
23:50:16FromDiscord<Generic> bit and
23:50:39FromDiscord<Generic> ah no
23:51:33FromDiscord<Elegantbeef> I dont even get what you're doing
23:52:16FromDiscord<Generic> me not really either, though converting things to a string and then back again is just scary
23:52:18FromDiscord<retkid> https://y.yarn.co/531e70aa-a107-4f0f-b819-ce7f4a3ce4a7_text.gif
23:52:42FromDiscord<Generic> what type is x?
23:52:43FromDiscord<Elegantbeef> Seems they have some type that they want to extract the first 3 ints from
23:52:43FromDiscord<retkid> In reply to @Generic "me not really either,": i have a bytechar, i need to convert into a its int numeric
23:52:55FromDiscord<Elegantbeef> "bytechar"
23:53:00FromDiscord<retkid> look
23:53:02FromDiscord<Generic> what is a bytechar?
23:53:16FromDiscord<Elegantbeef> retkid we're willing to help you dont have to act all defensive
23:53:27FromDiscord<retkid> y'know when you reading and you cast an array with a type
23:53:33FromDiscord<retkid> buffer[type]
23:53:37FromDiscord<retkid> this is of buffer[char]
23:53:44FromDiscord<retkid> that kind of data
23:53:51FromDiscord<Generic> so it's the raw bytes of some unspecified object?
23:53:57FromDiscord<retkid> yes
23:54:03FromDiscord<retkid> but i need it to be an int
23:54:11FromDiscord<Generic> ah
23:54:17FromDiscord<retkid> so it goes from (unprintable)=>(FF)=>256
23:54:18FromDiscord<Elegantbeef> `copyMem(dest.addr, myArray[0].addr, sizeof(dest))`
23:54:59FromDiscord<Generic> yeah memcpy go brr
23:55:57FromDiscord<retkid> i should learn more about memcpy
23:56:02FromDiscord<Generic> I think in Nim cast[int](object) should even work
23:56:13*wallabra_ joined #nim
23:56:21FromDiscord<Elegantbeef> Otherwise bitwise ops should work
23:56:31FromDiscord<Generic> why do you need bitwise ops for this?
23:56:37FromDiscord<Generic> ah you mean to combine bytes?
23:56:42FromDiscord<Elegantbeef> I really wish you provided more code so we could give other solutions
23:56:55FromDiscord<Elegantbeef> Instead of screaming about us offering to better your code
23:57:04FromDiscord<Generic> or pointer aliasing works too
23:57:06*wallabra quit (Ping timeout: 264 seconds)
23:57:16FromDiscord<Elegantbeef> strict aliasing says no
23:57:27FromDiscord<Generic> doesn't Nim compile with strict aliasing disabled?
23:57:37FromDiscord<Elegantbeef> Not by default
23:57:53*wallabra_ is now known as wallabra
23:58:07FromDiscord<Elegantbeef> I'd say it should but i dont know how beneficial strict aliasing is for performance
23:58:39FromDiscord<Generic> me neither, though I can say from experience that violating strict aliasing with strict aliasing enabled works 99% of the time
23:59:01FromDiscord<Elegantbeef> UB is UB and should be avoided
23:59:07FromDiscord<Generic> in the other 1% of the cases debugging is pretty painful, because in worst case it only happens in lto builds where there are no symbols at all
23:59:18FromDiscord<Generic> and you have to load your own binary into ghidra to figure out where the problem happens
23:59:22FromDiscord<Generic> but I'll do it anyway
