01:54:38FromDiscord<ElegantBeef> Maybe irc -> discord
01:54:51FromDiscord<Avahe> I think freenode just stood up a new server
01:59:13FromDiscord<ElegantBeef> I can pretend to agree to that
02:03:46FromDiscord<Avahe> hm? They did
02:03:55FromDiscord<Avahe> i just got on the new one
02:04:31FromDiscord<ElegantBeef> Prestige mistaking my comments for sincere doubt, shame
02:05:23FromDiscord<Avahe> for some reason we all have to register our accounts and channels again
02:05:28FromDiscord<codic> freenode will hopefully all die soon
02:05:36FromDiscord<codic> yeah the korean prince guy has all the old data
02:05:45FromDiscord<ElegantBeef> Yea cant wait for paidnode to take off
02:05:49FromDiscord<codic> not the in-exile freenode staff which moved it to librechat
02:05:54FromDiscord<codic> In reply to @ElegantBeef "Yea cant wait for": 👍
02:16:25*rockcavera quit (Remote host closed the connection)
02:17:36FromDiscord<deech> I maybe missing this but what is the default initialization value for a `proc`?
02:17:47FromDiscord<ElegantBeef> nil
02:18:16FromDiscord<ElegantBeef> Procs are pointers in nim as such they're nilable
02:20:27*rockcavera joined #nim
02:27:18FromDiscord<brainproxy> In reply to @brainproxy "weird thing... There's": fwiw, this turned out to be a matter of (w.r.t. the summary-example I used above), accidentally masking `var a {.threadvar.}` with a `let a` inside a proc where the compound let statement was spread across several lines and it just wasn't easy to spot the masking.
02:27:54FromDiscord<brainproxy> with `a =` dedented two spaces, everything worked wonderfully and as expected
02:28:28FromDiscord<brainproxy> (edit) "expected" => "expected."
02:29:16FromDiscord<brainproxy> somtimes whitespace delimiting is awesome... other times it gives me longings for a curl-braced dialect as a compile-time option 😿 😄
02:29:56FromDiscord<ElegantBeef> rainbow indentation + indention lines
02:29:56FromDiscord<Rika> A braced version would not save you from your error
02:31:14FromDiscord<brainproxy> In reply to @ElegantBeef "rainbow indentation + indention": is there such a thing in Emacs running in a terminal? wherein my being resides... always
02:31:24FromDiscord<Rika> Sure why not
02:31:34FromDiscord<Rika> Terminals have coloured support
02:32:08FromDiscord<ElegantBeef> Yea i dont see why not, indention lines can just be `|` and yea they can render an indent as a coloured block char if the bg cannot be set for an empty char
02:32:16FromDiscord<ElegantBeef> I know the indention line i have for my vim
02:32:17FromDiscord<brainproxy> I meant... do I have to write it myself 🤪
02:32:34FromDiscord<Rika> Likely
02:32:37FromDiscord<Rika> Oh
02:32:41FromDiscord<Rika> Misread
02:32:43FromDiscord<ElegantBeef> https://github.com/DarthFennec/highlight-indent-guides
02:32:43FromDiscord<Rika> Likely not
02:32:57FromDiscord<ElegantBeef> https://github.com/funkenblatt/rainbow-indent
02:33:15FromDiscord<Rika> I seriously don’t think a braced language would have saved you from that either
02:33:29FromDiscord<brainproxy> In reply to @Rika "I seriously don’t think": it's a good point, trying to think of why it would
02:33:51FromDiscord<brainproxy> coming mostly from a JS / lisp POV (in the latter would be a matter of parens, of course)
02:34:02FromDiscord<Rika> You’d still need to look for the matching braces, which usually is an extra feature
02:34:13FromDiscord<Rika> For the text editor
02:34:14FromDiscord<ElegantBeef> I think it's generally easy to blame things aside from yourself
02:34:30FromDiscord<ElegantBeef> Just say the sun was in your eyes and carry on
02:34:57FromDiscord<brainproxy> oh, I definitely blame myself, just feeling the 🔥 of wasting as much time as I did on this
02:35:16FromDiscord<ElegantBeef> If you dont waste time with stupid things are you even programming
02:35:17FromDiscord<brainproxy> otoh, wondering aloud if there's a way to make it easier to spot
02:35:28FromDiscord<Rika> To make what easier to spot
02:35:28FromDiscord<brainproxy> In reply to @ElegantBeef "If you dont waste": wisdom
02:35:31FromDiscord<Rika> Braces?
02:35:55FromDiscord<ElegantBeef> Eh they bitched and moaned and now know about indention guides + rainbow 😄
02:36:09FromDiscord<ElegantBeef> So now it's certainly their own fault
02:37:33FromDiscord<brainproxy> rainbow parens are nice, love 'em when I'm doing lisp/racket/etc..... sadly so little these days
02:38:04FromDiscord<Rika> I don’t use guides and rainbow
02:38:05FromDiscord<brainproxy> but Nim is awesome, actually thinking hard about why it was so easy to trip on this
02:38:09FromDiscord<Rika> I usually use folds
02:38:21FromDiscord<brainproxy> what editor do you use?
02:38:36FromDiscord<Rika> Neovim
02:38:49FromDiscord<ElegantBeef> I generally avoid folds
02:39:07FromDiscord<Rika> What why they’re so nice
02:39:16FromDiscord<Rika> Helps you focus on what you want
02:39:31FromDiscord<brainproxy> Cool. Emacs has folds too, I think, but I'm (at my own fault) stuck with patterns/practices that have become familiar, guess I need to start thinking out of the box
02:39:35FromDiscord<Rika> Hides the shitty code someone else made
02:39:48FromDiscord<brainproxy> In reply to @Rika "Neovim": Cool. Emacs has folds too, I think, but I'm (at my own fault) stuck with patterns/practices that have become familiar, guess I need to start thinking out of the box
02:40:03FromDiscord<Rika> Okay, that’s fine, it’s common
02:40:14FromDiscord<ElegantBeef> I occasionally use them when there is a lot of noise, but i dislike having code hidden from me 😄
02:40:34FromDiscord<Rika> Odd thing to dislike but ok
02:41:30FromDiscord<brainproxy> if had folds as an occasional tool I reach for when things are going weirdly wrong, that probably would have saved me today, much faster than just luckily–eventually noticing the inadvertent two extra spaces before `a = ...`
02:41:38FromDiscord<brainproxy> (edit) "as" => "was"
02:41:54FromDiscord<brainproxy> food for thought, for me, anyway
02:42:34*icebattle quit (Quit: leaving)
02:42:41FromDiscord<Rika> Well if you used it regularly you’d also notice some part of the code goes missing when it’s not supposed to so
02:46:58FromDiscord<ElegantBeef> Or if you used the fancy indention stuff you'd notice that it wasnt colour properly
02:47:15FromDiscord<ElegantBeef> Finally if you just didnt write code you'd never have had this issue to begin with
02:48:50FromDiscord<Rika> I don’t recognise color well so I don’t use rainbow indentations lol
02:48:57FromDiscord<brainproxy> sent a code paste, see https://play.nim-lang.org/#ix=3pZf
02:49:23FromDiscord<brainproxy> (edit) "https://play.nim-lang.org/#ix=3pZf" => "https://play.nim-lang.org/#ix=3pZg"
02:50:15FromDiscord<ElegantBeef> Or dont do that
02:50:44FromDiscord<Rika> In reply to @brainproxy "Or maybe I'll just": Why would that help?
02:50:56FromDiscord<ElegantBeef> Well the issue was due to using block let, they aliased a variable in the block
02:51:36FromDiscord<ElegantBeef> sent a code paste, see https://play.nim-lang.org/#ix=3pZh
02:51:41FromDiscord<brainproxy> because it was a `blah =` in the last `...` in the second code example of my code above was that accidentally indented into the let block
02:51:48FromDiscord<Rika> Then that’s just you being fuckin blind isn’t it
02:51:52FromDiscord<brainproxy> In reply to @Rika "Why would that help?": because it was a `blah =` in the last `...` in the second code example of my code above was that accidentally indented into the let block
02:51:58FromDiscord<ElegantBeef> Indeed
02:52:22FromDiscord<brainproxy> In reply to @Rika "Then that’s just you": yeah....... I guess, but still I struggled to spot it.
02:52:36FromDiscord<brainproxy> not "I guess", it was
02:52:38FromDiscord<Rika> Aren’t there shadowing warnings as well?
02:52:50FromDiscord<Rika> If not maybe that’s a good idea
02:53:49FromDiscord<brainproxy> I'll check later if there were shadowing warnings, maybe there were! something good to look or
02:54:04FromDiscord<brainproxy> (edit) "warnings," => "warnings (by reproducing my error)," | "or" => "for"
02:54:14FromDiscord<ElegantBeef> I dont think there is
02:54:53FromDiscord<Rika> Well maybe shadowing should be more explicit
02:55:26FromDiscord<ElegantBeef> Eh i think a hint of shadowing that can be turned into an error is better
02:55:43FromDiscord<Rika> And if you have shadows that are intended?
02:55:59FromDiscord<Rika> But want the error
02:56:02FromDiscord<ElegantBeef> Well i personally wouldnt have the hint on
02:56:03FromDiscord<brainproxy> maybe okay, still could have been a helpful clue to me today
02:56:29FromDiscord<ElegantBeef> Something more explict like `let a {.shadowed.} = 100` just seems annoying
02:58:17FromDiscord<Rika> Well it should probably be as you said hint as error, but also be able to be disabled per variable
02:58:28FromDiscord<Rika> Now get working on it beef lol
02:58:31FromDiscord<Rika> I kid
02:58:31FromDiscord<brainproxy> right, a mechanism to pint it down
02:58:40FromDiscord<Rika> To what?
02:58:44FromDiscord<brainproxy> (edit) "pint" => "pin" | "down" => "down, in dire straits"
02:58:49FromDiscord<Rika> Is this a beer joke I don’t understand
02:58:59FromDiscord<brainproxy> typo, long day 🤪
02:59:22FromDiscord<Rika> Yeah nowadays for the north hemisphere the days are long indeed
02:59:26FromDiscord<brainproxy> plus vindo
02:59:31FromDiscord<brainproxy> (edit) "vindo" => "vino"
02:59:53FromDiscord<Rika> I don’t know what vino is other than it means something in Esperanto probably
03:00:26FromDiscord<brainproxy> Italian
03:01:12FromDiscord<brainproxy> anyway, late here, thanks for the feedback, quite helpful, for thinking outside the box I sometimes pack myself into

03:57:15FromDiscord<fenrave> ah nevermind

03:58:10FromDiscord<fenrave> for future reference to anyone who can't run any nim related commands, this is how you set up the path variable https://media.discordapp.net/attachments/371759389889003532/854208134121127936/unknown.png
03:58:22FromDiscord<fenrave> god speed to all who search in discord for the answer
04:08:32*rockcavera quit (Remote host closed the connection)
05:38:09FromDiscord<codic> how do I define a packed struct in nim?
05:45:01FromDiscord<ElegantBeef> @codic https://nim-lang.org/docs/manual.html#implementation-specific-pragmas-bitsize-pragma and align i assume, though i'm a numpty that doesnt know what "packed struct" actually means 😄
05:45:56FromDiscord<codic> a packed struct is one where there is no padding between the elements, not a bitfield
05:46:08FromDiscord<codic> in c/c++ there is only compiler specific attributes no proper way to do it
05:46:13FromDiscord<codic> https://nim-lang.org/docs/manual.html#foreign-function-interface-packed-pragma oh here
05:46:34FromDiscord<codic> ok that's fine I don't need to define a packed struct which would use gc'd memory, just bind to one
06:23:30FromDiscord<codic> sent a code paste, see https://play.nim-lang.org/#ix=3pZQ
06:24:41FromDiscord<codic> sent a code paste, see https://play.nim-lang.org/#ix=3pZR
06:24:58FromDiscord<codic> cuz it works
06:25:02FromDiscord<codic> but idk if im relying on u
06:25:03FromDiscord<codic> (edit) "u" => "ub"
06:25:30FromDiscord<codic> ig its not if nim structs compile directly to C ones without adding anything else
06:30:19FromDiscord<Rika> They do I believe
06:30:51FromDiscord<codic> should be fine then
06:34:51FromDiscord<codic> sent a code paste, see https://play.nim-lang.org/#ix=3pZT
06:35:15FromDiscord<Rika> No
06:37:14FromDiscord<codic> using `{.experimental: "codeReordering".}` works, i very much wish it was default because i really want to develop with it
06:45:10FromDiscord<Rika> It is not stable and may cause unexpected effects
06:47:41FromDiscord<codic> yeah ill just do the former
06:47:57FromDiscord<ElegantBeef> Plus there is even debate whether it should exist 😛
06:48:29FromDiscord<codic> forward declarations are bad bad bad
06:48:36FromDiscord<codic> tho i realize it might be hard to implement a good one
06:48:47FromDiscord<codic> (edit) "one" => "lookahead algorithm"
06:50:59FromDiscord<ElegantBeef> I mean they're somewhat annoying but atleast the code only has one flow 😄

08:11:06FromDiscord<Clonkk> Nim suggest being itself again
08:11:44FromDiscord<Clonkk> At least 30 process of over 200 MiB of RAM each
08:22:04FromDiscord<ElegantBeef> Properly organized project?
08:22:27FromDiscord<Clonkk> Typical Nimble package with say, ~10 files
08:22:32FromDiscord<Clonkk> less than 1k loc
08:22:37FromDiscord<ElegantBeef> Are you using saems extension?
08:22:55FromDiscord<Clonkk> On Onivim2, yes
08:23:05FromDiscord<ElegantBeef> I more just mean is there a single entry or have you setup the project paths if there is more than one
08:24:51FromDiscord<Clonkk> I don't know, I just openend the project as usual. Computer was getting slow, fan started blowing I was just able to take this screenshot before having to maunally reboot
08:26:02FromDiscord<ElegantBeef> Generally speaking i dont think the extension dispatches more than a single instance of nimsuggest unless the project isnt setup "properly", is it a open project?
08:27:16FromDiscord<ElegantBeef> by open i mean open source of course
08:27:28FromDiscord<Clonkk> No it is not open source. I don't use projects setup (compile everything in command line). There's no setup to do. I just use the extension for auto completion and highlighting
08:28:07FromDiscord<ElegantBeef> That's my point though, if the project isnt setup properly as in single entry and the extension doesnt know that it goes a little haywire with the nimsuggest instances
08:28:47FromDiscord<ElegantBeef> I could be wrong about the cause of this, but just spreading what it might be
08:32:13FromDiscord<haxscramper> It seems like IRC bot died along with all the freenode, but discord → matrix, gitter → matrix is working fine
08:33:19FromDiscord<ElegantBeef> Yea freenode axed all users/servers
08:33:40FromDiscord<ElegantBeef> As such the irc bridge to libera or w/e is also dead since it was hosted on freenode
08:36:50FromDiscord<Rika> In reply to @ElegantBeef "Yea freenode axed all": What lol
08:37:32FromDiscord<ElegantBeef> https://www.reddit.com/r/linux/comments/o0263h/all_freenode_channels_and_users_gone/ atleast according to this
08:42:01FromDiscord<Rika> yeah i read
08:45:58FromDiscord<Clonkk> In reply to @ElegantBeef "I could be wrong": Could also be related to Onivim itself, it had an error message in logs regarding the extension, I opened an issue on the Onivim repo
08:46:12FromDiscord<Clonkk> Can't reproduce ith VSCOdium 🙂
08:46:13FromDiscord<Rainbow Asteroids> they killed freenode entirely now?
08:46:20FromDiscord<Rika> yes
08:46:23FromDiscord<Rainbow Asteroids> why
08:46:42FromDiscord<Rika> because rasengan thought it was needed
08:46:48FromDiscord<ElegantBeef> Ah sounds good then, do you have the issue still where autocomplete inserts another character?
08:47:06FromDiscord<ElegantBeef> Couldnt use it anymore because of that just too annoying to have to go back to the first character and delete it
08:47:56FromDiscord<Clonkk> In reply to @ElegantBeef "Ah sounds good then,": Eh, no I don't have this one. Just nimsuggest go crazy sometimes. It's not even systematic
08:48:24FromDiscord<Clonkk> I switch back and forth between onivim and neovim
08:48:30FromDiscord<Clonkk> (edit) "I switch back and forth between onivim and neovim ... " added "anyway"
08:52:40FromDiscord<ElegantBeef> I cannot get around to setting up nvim to my liking so just avoid using vim 😄
08:52:56FromDiscord<Rika> what?
08:52:59FromDiscord<Rika> how?
08:53:41FromDiscord<ElegantBeef> What do you mean
08:54:15FromDiscord<Rika> arent you already using vim or something
08:54:19FromDiscord<Rika> you just copy the configs
08:54:31FromDiscord<ElegantBeef> Nah i default to vscode, and was testing out onivim2
08:55:04FromDiscord<ElegantBeef> onivim2 isnt actually vim, it does graphical rendering and has a vscode like gui
08:55:11FromDiscord<Rika> smh, fucking numpties
08:55:21FromDiscord<ElegantBeef> Indeed
08:55:28FromDiscord<Rika> even then would the configs not be the same?
08:55:37FromDiscord<ElegantBeef> Nope it supports vscode extensions
08:56:16FromDiscord<Rika> eh
08:56:37FromDiscord<ElegantBeef> just to show what onivim has 😄 https://media.discordapp.net/attachments/371759389889003532/854283238029393934/unknown.png

09:06:12FromDiscord<mlokis> at this point my game is randomly crashing at different places, guess i cannot use threads after all
09:07:25FromDiscord<System64 ~ Flandre Scarlet> I want to try something↵Is it possible to generate sound with the PC beeper with Nim?
09:09:24FromDiscord<ElegantBeef> Fairly certain it's not possible to do that with anything but your motherboards firmware, and it'd be odd if you could
09:09:43FromDiscord<ElegantBeef> So probably technically yes, but practically no
09:10:09FromDiscord<Rainbow Asteroids> why use onivim of nvim
09:10:28FromDiscord<Rainbow Asteroids> (edit) "of" => "over"
09:11:16FromDiscord<ElegantBeef> Vscode extensions, gui rendered, easier to setup
09:13:38FromDiscord<mlokis> when nim runtime is crashing its maybe best to give up on threads
09:14:02FromDiscord<ElegantBeef> Or find a minimal reproduction and make an issue 😄
09:14:22FromDiscord<mlokis> its really vierd though
09:14:47FromDiscord<mlokis> when i stress test it in minimal environment it works
09:15:02FromDiscord<mlokis> worst thing is that its a data race problem
09:15:19FromDiscord<ElegantBeef> How are you sharing the object, just casting gcsafe?
09:15:25FromDiscord<mlokis> no
09:18:24FromDiscord<mlokis> In reply to @ElegantBeef "How are you sharing": compiler is not complaining about my code. All i em doing is sharing state between threads. I would expect my code crashes because of data race but problem is not in my logic. Stacktrace always points to some internal runtime code
09:19:00FromDiscord<ElegantBeef> Yea i know it's not, i was just curious about how you were going about it and how the data race was introduced
09:21:34FromDiscord<System64 ~ Flandre Scarlet> In reply to @ElegantBeef "just to show what": What's your theme? I like it

09:22:33FromDiscord<mlokis> but i also happens on different places, seems like memory is freen on multiple places at the same time
09:23:18FromDiscord<mlokis> (edit) "freen" => "freed"

09:28:14FromDiscord<System64 ~ Flandre Scarlet> you prefer a pastebin / sending a text file?
09:29:14FromDiscord<Rika> prolly look into winim
09:29:18FromDiscord<Rainbow Asteroids> In reply to @System64 "I want to try": I know of `beep`, which is a program for Linux systems that does this. IDK much about windows tho. https://github.com/johnath/beep/
09:29:51FromDiscord<ElegantBeef> A simple function doc would've been enough to show what it does
09:30:01FromDiscord<ElegantBeef> I'm rather surprised this is actually possible to be honest 😄
09:31:53FromDiscord<Rainbow Asteroids> well, windows skipped version 9 to avoid breaking programs that were made for windows 95/98, so im not too suprised the kernel has code for the PC speaker

10:01:33FromDiscord<System64 ~ Flandre Scarlet> what's that?
10:14:55FromDiscord<mlokis> the bug was actually on my side
10:15:03FromDiscord<mlokis> thank god
10:18:29FromDiscord<Rainbow Asteroids> lower level constructs, as in constructs that are lower level, so implement the square wave stuff yourself with libraries that let you access the beeper
10:19:13FromDiscord<Rainbow Asteroids> (edit) "lower level constructs, as in constructs that are lower level, so implement the square wave stuff yourself with libraries that let you ... access" added "directly"
10:21:29*ebb joined #nim
10:31:01FromDiscord<System64 ~ Flandre Scarlet> https://github.com/johnnovak/nim-riff↵Is it normal I can't nimble install that?
10:38:06*xet7 quit (Quit: Leaving)
10:41:39FromDiscord<pointystick> I couldn't see that package on the main Nimble directory. Perhaps he hasn't published it? I was able to install it using the URL: ↵↵nimble install https://github.com/johnnovak/nim-riff
10:44:07FromDiscord<System64 ~ Flandre Scarlet> ah I can do that
11:40:05FromDiscord<shirleyquirk> @mlokis it could be a bug in arc but you're using unsafe `ptr` so much everywhere its hard to say. a MRE if you can would be excellent, either so someone can fix the bug in arc or can help fix the bug in your code.
11:40:28FromDiscord<mlokis> In reply to @shirleyquirk "<@343028072095809536> it could be": no i fixed the issue
11:40:33FromDiscord<mlokis> it was my fault
11:40:38FromDiscord<shirleyquirk> sweet! what was it?
11:41:10FromDiscord<mlokis> well i thought i don't have to allocate channels on shared heap since i em using arc
11:41:36FromDiscord<mlokis> but it seams i have to at least allocate them manually
11:41:48FromDiscord<mlokis> (edit) "seams" => "seems"
11:43:34FromDiscord<shirleyquirk> ah, so they don't get collected by the gc. still seems like something that should work, but glad you found a workaround
11:44:20FromDiscord<mlokis> In reply to @shirleyquirk "ah, so they don't": no they just do not work properly whe not allocated
11:44:51FromDiscord<mlokis> memory leaks do not crash your program with that kind of error
11:45:06FromDiscord<shirleyquirk> double free's do, am i miles off?
11:45:20FromDiscord<shirleyquirk> sorry, use-after-free
11:46:29FromDiscord<mlokis> i was reusing same channels for duration of program
11:47:33FromDiscord<shirleyquirk> i was hypothesizing that they were `=destroy`ed prematurely
11:47:49FromDiscord<mlokis> maybe
11:49:51FromDiscord<Zachary Carter> It's never good news when your program also crashes dr. memory
13:00:40FromDiscord<System64 ~ Flandre Scarlet> If I a question about rounding↵If the decimals are above 0.5, alright I round up↵if the decimals are under 0.5, alright I round down↵But what if the decimals are 0.5?
13:02:26FromDiscord<Rika> up
13:02:33FromDiscord<Rika> usually up
13:03:04FromDiscord<System64 ~ Flandre Scarlet> alright
13:08:25FromDiscord<System64 ~ Flandre Scarlet> sent a code paste, see https://play.nim-lang.org/#ix=3q1R
13:08:54FromDiscord<Rika> complicated
13:09:19FromDiscord<haxscramper> There is a round in stdlib, you can just truncate results from `int` to `uint16`
13:10:07FromDiscord<System64 ~ Flandre Scarlet> oh alright, and this rounding up or down depending if it's over x.5 or under x.5?
13:10:42FromDiscord<mlokis> use floor and ceil
13:12:42FromDiscord<mlokis> sent a code paste, see https://play.nim-lang.org/#ix=3q1T
13:13:15FromDiscord<mlokis> (edit) "https://play.nim-lang.org/#ix=3q1T" => "https://play.nim-lang.org/#ix=3q1U"
13:13:25FromDiscord<mlokis> you get the idea
13:13:28FromDiscord<mlokis> (edit) "https://play.nim-lang.org/#ix=3q1U" => "https://play.nim-lang.org/#ix=3q1V"
13:13:41FromDiscord<System64 ~ Flandre Scarlet> isn't it a.uint16 at the end?
13:14:03FromDiscord<mlokis> no
13:14:09FromDiscord<mlokis> why?
13:14:31FromDiscord<mlokis> i em returning implicitly
13:14:54FromDiscord<System64 ~ Flandre Scarlet> Ah I see
13:15:41FromDiscord<System64 ~ Flandre Scarlet> and a.round() floor by default?
13:15:57FromDiscord<mlokis> round rounds
13:16:15FromDiscord<mlokis> it cuts the decimal
13:16:22FromDiscord<System64 ~ Flandre Scarlet> ah yeah so floor
13:16:35FromDiscord<mlokis> you can use floor if you want
13:18:42FromDiscord<System64 ~ Flandre Scarlet> https://media.discordapp.net/attachments/371759389889003532/854349195904942110/unknown.png
13:20:19FromDiscord<haxscramper> `round` is in `math`
13:20:43FromDiscord<haxscramper> You can use search in the nim docs to figure out where function comes from
13:21:01FromDiscord<System64 ~ Flandre Scarlet> alright
13:42:09FromDiscord<Zachary Carter> app verifier on windows is a godsend
13:42:20FromDiscord<Zachary Carter> (edit) "godsend" => "god send"
13:42:45FromDiscord<System64 ~ Flandre Scarlet> sent a code paste, see https://play.nim-lang.org/#ix=3q26
13:50:40FromDiscord<shirleyquirk> if you start with uint, stick with int math. If you want 4 most significant bits of a uint, that's a `shr`
13:51:28FromDiscord<System64 ~ Flandre Scarlet> what does it mean?
13:55:54FromDiscord<shirleyquirk> hmm. Maybe I walked into something I can't handle.
13:58:12FromDiscord<Rika> quantize just means "value / max_value_for_bytesize = value_new / max_value_for_new_bytesize"
13:58:48FromDiscord<System64 ~ Flandre Scarlet> yeah
13:59:01FromDiscord<Rika> In reply to @Rika "quantize just means "value": oops, max + 1 actually
13:59:07FromDiscord<Rika> wait no, no +1
14:00:21FromDiscord<Rika> so (round(a.float/uint16.high16)) i guess?
14:00:52FromDiscord<Rika> no clamp needed
14:01:19FromDiscord<System64 ~ Flandre Scarlet> what is clamp? Sorry I usually speak french
14:02:33FromDiscord<shirleyquirk> limiter? Keep values within a range
14:02:55FromDiscord<System64 ~ Flandre Scarlet> ah yeah
14:03:27FromDiscord<System64 ~ Flandre Scarlet> isn't it ((round(a.float/uint16.high)16))?
14:04:06FromDiscord<shirleyquirk> It's the same while you're using floats
14:05:40FromDiscord<Zachary Carter> that won't work
14:06:09FromDiscord<Zachary Carter> `((round(a.float/uint16.high.float)16))` probably
14:06:23FromDiscord<Zachary Carter> if you want to divide integers use `div` not `/`
14:08:25FromDiscord<Rika> why round over the percentage? that will give literal 0 or 1
14:08:31FromDiscord<Rika> you do it once you multiply from 16
14:08:52FromDiscord<Rika> i forgot the bridge is down
14:10:40FromDiscord<Rika> https://media.discordapp.net/attachments/371759389889003532/854362273619771422/unknown.png
14:14:14FromDiscord<System64 ~ Flandre Scarlet> You just converted to 1-bit
14:15:04FromDiscord<Rika> i did not
14:15:35FromDiscord<Rika> https://media.discordapp.net/attachments/371759389889003532/854363510284222474/unknown.png
14:15:40FromDiscord<Rika> the OTHER one
14:15:42FromDiscord<System64 ~ Flandre Scarlet> sent a code paste, see https://paste.rs/pJS
14:15:51FromDiscord<Rika> zach converted to one bit
14:20:53FromDiscord<System64 ~ Flandre Scarlet> In reply to @Rika "so (round(a.float/uint16.high*16)) i guess?": That?
14:21:20FromDiscord<Rika> ((round(a.float/uint16.high.float16)))
14:21:36FromDiscord<Rika> (edit) "((round(a.float/uint16.high.float16)))" => "round(a.float/uint16.high.float16)"
14:22:32FromDiscord<Rika> ah fuck wait
14:22:33FromDiscord<Rika> 15
14:23:07FromDiscord<Rika> a.float/uint16.high.float == 1↵a.float/uint16.high.float 16 == 16 # wrong
14:23:15FromDiscord<Rika> so its `round(a.float/uint16.high.float15)`
14:25:14FromDiscord<Zachary Carter> sent a long message, see http://ix.io/3q2b
14:31:06FromDiscord<System64 ~ Flandre Scarlet> It's already more accurate but
14:31:13FromDiscord<System64 ~ Flandre Scarlet> it's signed
14:32:54FromDiscord<Rika> what do you mean?
14:33:31FromDiscord<Rika> a cannot be negative -> a.float cannot be negative -> a.float/uint16.high.float cannot be negative -> etc.etc. -> the whole expression is never negative
14:33:55FromDiscord<System64 ~ Flandre Scarlet> I'll inspect what's happened
14:35:19FromDiscord<System64 ~ Flandre Scarlet> Ah it's fixed I just had to add 128 to the result
14:35:49FromDiscord<Rika> what? why?
14:46:30FromDiscord<mlokis> @System64 ~ Flandre Scarlet are you like doing your homework or something
14:48:22FromDiscord<Zachary Carter> In reply to @Zachary Carter "I think I found": here's the bug report: https://github.com/nim-lang/Nim/issues/18271
14:53:54FromDiscord<System64 ~ Flandre Scarlet> In reply to @mlokis "<@!380360389377916939> are you": No just for fun
14:54:15FromDiscord<System64 ~ Flandre Scarlet> Like a challenge for myself
14:55:35FromDiscord<mlokis> In reply to @System64 "Like a challenge for": You want a challenge ha? Make a quicksort then.
14:55:56FromDiscord<System64 ~ Flandre Scarlet> I didn't learned that sort lol
14:55:57FromDiscord<mlokis> its not that hard but not too easy
14:56:14FromDiscord<mlokis> then just learn it, its usefull
14:56:25FromDiscord<mlokis> or binary search thats simpler
14:56:26FromDiscord<System64 ~ Flandre Scarlet> I'll check it
14:56:44FromDiscord<System64 ~ Flandre Scarlet> Ah didn't learned binary search
14:57:24FromDiscord<mlokis> or you can visit leetcode they have lot of coding challenges
14:58:17FromDiscord<System64 ~ Flandre Scarlet> Oh I should check it↵I want to make a Danmaku engine too
14:58:29FromDiscord<mlokis> what is that?
14:58:36FromDiscord<System64 ~ Flandre Scarlet> Bullet hell
14:59:05FromDiscord<System64 ~ Flandre Scarlet> Like Touhou Project
14:59:56FromDiscord<mlokis> i see, well that should be easy. its all just angles and hacks
15:00:44FromDiscord<System64 ~ Flandre Scarlet> I think using vectors is a good idea
15:01:21FromDiscord<mlokis> what else for a love of god would you use, complex numbers?
15:01:51FromDiscord<System64 ~ Flandre Scarlet> By vectors I meant the ones you use in physics
15:02:03FromDiscord<Rika> arent complex numbers still vector
15:02:04FromDiscord<Rika> s
15:02:17FromDiscord<mlokis> thats a joke he did not get
15:02:45FromDiscord<mlokis> poor joke though
15:02:58FromDiscord<Rika> not a lot of people know that complex numbers can be vectors...
15:03:23FromDiscord<mlokis> In reply to @Rika "not a lot of": its really sad
15:03:35FromDiscord<Rika> its pretty handy
15:03:39FromDiscord<Rika> to know, i mean
15:03:52FromDiscord<mlokis> no whole concept of complex numbers is useles
15:04:10FromDiscord<mlokis> the `i` exists just so you cannot add app that numbers
15:04:11*johnnynitwits quit (Read error: Connection reset by peer)
15:04:20FromDiscord<mlokis> (edit) "app" => "up"
15:04:41FromDiscord<System64 ~ Flandre Scarlet> But if you have a better idea, don't hésitate to suggest
15:04:44FromDiscord<mlokis> i feel like complex numbers are just reinvention of vectors
15:05:13FromDiscord<InventorMatt> I believe complex numbers came before vectors
15:05:22FromDiscord<mlokis> not really
15:05:30FromDiscord<mlokis> vector is an axiom
15:05:35FromDiscord<mlokis> thats really old
15:05:54FromDiscord<System64 ~ Flandre Scarlet> In physics, a move vector is described by a direction and speed (by the lenght of the vector)
15:06:28FromDiscord<mlokis> vector can be described in multiple wais
15:06:51FromDiscord<mlokis> `x y` or `angle length`
15:06:59FromDiscord<System64 ~ Flandre Scarlet> and that's why I was thinking to vectors↵To describe the direction of the bullet and the speed of it
15:07:13FromDiscord<mlokis> you can easily convert between the two but it is rather costy calculation
15:07:27FromDiscord<InventorMatt> Even quaternions are older than vectors as we know them. It's why in the 1800s alot of physics was described using quaternions
15:07:29FromDiscord<mlokis> in game you usually need both
15:07:51FromDiscord<System64 ~ Flandre Scarlet> I should check how a bullet hell is built
15:08:04FromDiscord<mlokis> its very simple
15:08:19FromDiscord<mlokis> you have 3 axioms i can think off
15:08:24FromDiscord<mlokis> bullet source
15:08:27FromDiscord<mlokis> bullets
15:08:29FromDiscord<mlokis> player
15:08:53*blackbeard420 joined #nim
15:09:02FromDiscord<mlokis> all you have to define is rendering collision detection and phizics
15:09:24FromDiscord<mlokis> phyzics are simple as all you need is linear movement
15:09:40FromDiscord<System64 ~ Flandre Scarlet> for the player I can just use X and Y movement
15:10:02FromDiscord<System64 ~ Flandre Scarlet> for the bullet source too
15:11:13FromDiscord<mlokis> sent a code paste, see https://play.nim-lang.org/#ix=3q2B
15:11:15*blackbeard420 quit (Client Quit)
15:11:36FromDiscord<mlokis> you could also add a texture data
15:11:54FromDiscord<mlokis> but its lot better to use ecs
15:12:06FromDiscord<mlokis> it makes things simpler and faster
15:12:31FromDiscord<System64 ~ Flandre Scarlet> Oh that's not so hard I guess
15:12:58FromDiscord<mlokis> i have to publish my ecs library
15:13:09FromDiscord<mlokis> you can use it if you want
15:13:15FromDiscord<System64 ~ Flandre Scarlet> what is ECS? for textures?
15:13:34FromDiscord<mlokis> no its a EntityComponentSystem
15:13:41*teasea quit (Quit: teasea)
15:13:51FromDiscord<mlokis> for example
15:14:03FromDiscord<mlokis> both bullet player and turret
15:14:08FromDiscord<mlokis> can be drawn
15:14:20FromDiscord<mlokis> so you can make texture component
15:14:28FromDiscord<mlokis> all tree have a position
15:14:37FromDiscord<mlokis> this is a position component
15:14:59FromDiscord<mlokis> each entity that has both position and texture can be drawn
15:15:39FromDiscord<mlokis> what ecs does is that it allows you to define one logic for all entities with given components
15:16:32FromDiscord<mlokis> you can read about all this on internet btw
15:17:00FromDiscord<System64 ~ Flandre Scarlet> Oh seem interesting↵Did you already gamedev?
15:19:17FromDiscord<mlokis> i made one kid of complete game but newer made any money so maybe
15:19:27FromDiscord<mlokis> (edit) "kid" => "kind"
15:19:42FromDiscord<System64 ~ Flandre Scarlet> I want to make games
15:19:50FromDiscord<mlokis> so do them
15:20:13FromDiscord<System64 ~ Flandre Scarlet> I already made a platformer prototype on GameMaker Studio
15:20:22FromDiscord<mlokis> but if a would recomend you something dont do it in nim from the beginning
15:20:49FromDiscord<mlokis> In reply to @System64 "I already made a": is see so you made some games
15:21:01FromDiscord<System64 ~ Flandre Scarlet> Why and which language should I use?
15:21:05FromDiscord<mlokis> i also made platformer as my first game
15:21:08FromDiscord<Rika> the one you already know
15:21:41FromDiscord<mlokis> when i was starting i used python but then i changed to dodot engine
15:21:46FromDiscord<mlokis> (edit) "dodot" => "godot"
15:21:51FromDiscord<System64 ~ Flandre Scarlet> I know Java well and I have a bit of experience with C#↵C# is a pretty good language for games
15:21:58FromDiscord<mlokis> godot engine is really good but slow
15:22:12FromDiscord<System64 ~ Flandre Scarlet> 'cause of interpreted language?
15:22:40FromDiscord<mlokis> yes, its written in c++ but it uses python like scripting langiuage
15:22:53FromDiscord<mlokis> good enough for most of the games
15:22:59FromDiscord<System64 ~ Flandre Scarlet> I'm feared of C++
15:23:25FromDiscord<mlokis> you normalid dont use c++ when wirting games in godot
15:23:39FromDiscord<mlokis> only if you want to add custom plugins and stuff
15:24:07FromDiscord<System64 ~ Flandre Scarlet> The reason why I'm feared of C++ is 'cause of this demonic thing called Pointer
15:24:24FromDiscord<mlokis> and what do you think nim has
15:24:34FromDiscord<mlokis> it also has them
15:24:54FromDiscord<System64 ~ Flandre Scarlet> they're not as necessary as in C, and I find them more explicits
15:25:48FromDiscord<haxscramper> pointers are the least scary thing in C++
15:26:26FromDiscord<mlokis> C++ is just big pile of shit that will be compiling for days
15:26:40FromDiscord<mlokis> because of poor design decisions
15:26:56FromDiscord<mlokis> if you want to use something, then use zig
15:27:07FromDiscord<System64 ~ Flandre Scarlet> is it a programming language?
15:27:13FromDiscord<mlokis> yes
15:27:37FromDiscord<VesperSparrow> In reply to @System64 "is it a programming": no, it is superset.
15:28:00FromDiscord<mlokis> In reply to @VesperSparrow "no, it is superset.": oh no you call you serpent zig
15:28:26FromDiscord<mlokis> fuck
15:28:36FromDiscord<haxscramper> I don't think Zig is a superset of anything, even C, and I don't think it qualifies as C++ replacement either way
15:28:40FromDiscord<Zachary Carter> In reply to @mlokis "C++ is just big": huh?
15:28:41FromDiscord<mlokis> my dislexi got me
15:28:59FromDiscord<System64 ~ Flandre Scarlet> I'm interested in Python too but I'm worried about its slowness
15:29:49FromDiscord<Zachary Carter> also did you say pointers aren't necessary in C?
15:29:51FromDiscord<mlokis> In reply to @Zachary Carter "huh?": i em joking of course but language is so overfeatured that the compile time can get to an hour
15:30:25FromDiscord<System64 ~ Flandre Scarlet> In reply to @Zachary Carter "also did you say": They are necessary in C
15:30:39FromDiscord<haxscramper> well, C without raw pointers is just ... what?
15:30:41FromDiscord<Zachary Carter> compile times can be long in any language if you're doing stupid shit
15:30:59FromDiscord<Zachary Carter> C++ compile times are long, but there are ways to alleviate that
15:31:12FromDiscord<haxscramper> like bying more servers
15:31:14FromDiscord<leorize> you don't have to do stupid things for compile time to be long in nim :p
15:31:18FromDiscord<Zachary Carter> Zig isn't even really comparable to C++ though. It's meant to be a C replacement.
15:32:08FromDiscord<mlokis> yes but i still consider it better then cpp
15:32:11FromDiscord<VesperSparrow> What is Zig?
15:32:12FromDiscord<Zachary Carter> So I wouldn't tell someone not to use C++ and to just use Zig instead, because it doesn't really make much sense?
15:32:31FromDiscord<Zachary Carter> then you probably consider C better than C++
15:32:36FromDiscord<Zachary Carter> and this is all subjective
15:32:44FromDiscord<leorize> In reply to @VesperSparrow "What is Zig?": ziglang.org
15:33:06FromDiscord<Zachary Carter> the fact is, Zig is much simpler than C++
15:33:09FromDiscord<Zachary Carter> by design
15:33:17FromDiscord<Zachary Carter> C++ is popular for a reason
15:33:23FromDiscord<mlokis> i like simplicity
15:33:26FromDiscord<Zachary Carter> Well that's cool
15:33:45FromDiscord<Zachary Carter> but I wouldn't compare apples to oranges and tell someone that wants an orange to go eat an apple 🙂
15:34:06FromDiscord<Zachary Carter> Zig is great, especially zigcc
15:34:15FromDiscord<Zachary Carter> but I don't think C++ developers are jumping ship to Zig anytime soon
15:34:19FromDiscord<Zachary Carter> or like, ever
15:34:39FromDiscord<Zachary Carter> maybe C++ will get a zig backend
15:34:46FromDiscord<Zachary Carter> some c++ compiler
15:35:11FromDiscord<Zachary Carter> but they're just not on the same level of abstraction
15:35:12FromDiscord<VesperSparrow> like rust oh.
15:35:35FromDiscord<Zachary Carter> I don't know what Rust has to do with this haha
15:35:40FromDiscord<System64 ~ Flandre Scarlet> Nim is compiled to C and after compiled to binary right?
15:35:49FromDiscord<mlokis> rust is safe, but sometimes safeness is not efficiency
15:35:55FromDiscord<Zachary Carter> Nim is compiled to C or C++ or Objective-C or JavaScript
15:36:26FromDiscord<Zachary Carter> if it's compiled to C or C++ or Objective-C it will invoke a compiler for one of those languages after compiling the Nim code to the specified language
15:36:29FromDiscord<mlokis> i mean rust sometimes disalows both
15:36:50FromDiscord<Zachary Carter> you can of course override the compiler
15:37:07FromDiscord<Zachary Carter> so, for instance, you can compile Nim code to C and then invoke zigcc and target another platform
15:37:31FromDiscord<System64 ~ Flandre Scarlet> and can I change the compiler?↵Using TCC instead of GCC for exemple
15:37:44FromDiscord<Recruit_main707> ys
15:37:49FromDiscord<VesperSparrow> Hey, I was just talking about Zig's syntax.
15:37:53FromDiscord<Recruit_main707> --cc:[compiler]
15:38:08FromDiscord<Recruit_main707> write something random and a list of compilers will appear
15:38:16FromDiscord<VesperSparrow> None of these languages ​​have a clean, self-explanatory syntax.↵I pass Golang alone.
15:38:23FromDiscord<Zachary Carter> In reply to @VesperSparrow "Hey, I was just": I don't think Rust and Zig's syntax are at all alike
15:38:23FromDiscord<Rika> zig rust go nim d, theyre all languages for different folk
15:39:10FromDiscord<mlokis> In reply to @VesperSparrow "None of these languages": golang is love
15:39:30FromDiscord<Zachary Carter> minus generics
15:39:34FromDiscord<VesperSparrow> I'm just talking about syntax.↵What I'm using the language for is out of context.
15:39:42FromDiscord<mlokis> but it will get less simple after generics
15:39:44FromDiscord<Zachary Carter> I dislike golang personally
15:40:00FromDiscord<Rika> simple does not mean good
15:40:01FromDiscord<Zachary Carter> yeah, well parametric polymorphism is nice
15:40:11FromDiscord<Rika> simple usually means repetition
15:40:28FromDiscord<System64 ~ Flandre Scarlet> do you like Java?
15:40:39FromDiscord<Rika> yeah its simple, yeah you can read the code at a glance, you have to read a lot of code though
15:40:46FromDiscord<mlokis> In reply to @System64 "do you like Java?": 💩
15:41:06FromDiscord<Zachary Carter> this is all kind of #off-topic just FYI
15:41:43FromDiscord<Zachary Carter> (edit) "#off-topic" => "#offtopic"
15:42:05FromDiscord<Zachary Carter> can have your language holy wars there 🙂
15:42:20FromDiscord<System64 ~ Flandre Scarlet> Let's go there!
15:51:23FromDiscord<VesperSparrow> Does Nim have destruction for objects?
15:51:45FromDiscord<leorize> yes
15:52:05FromDiscord<leorize> via a mechanism called destructors: http://nim-lang.github.io/Nim/destructors.html
15:52:40FromDiscord<leorize> though I'd note that only when used with `--gc:orc` or `--gc:arc` would it be reliable

16:44:49FromDiscord<codic> https://github.com/nim-lang/Nim/blob/devel/compiler/ccgliterals.nim#L15 interesting, seqs need some language support?
16:46:48FromDiscord<haxscramper> For literal creation
16:48:19FromDiscord<codic> so if I wanted to implement my own data structure I couldn't use this syntax? `var x: data[T] = [a,b,c]`
16:48:32FromDiscord<codic> id have to do `var x: data[T] = data(a,b,c)` or something?
16:49:44FromDiscord<haxscramper> BTW `@` is an operator, not a special syntax, so you can do `@![a, b, c]`
16:50:17FromDiscord<haxscramper> But in general I don't think you can implement `var x: <T> = not <T>`
16:50:47FromDiscord<haxscramper> Just as you can' implement `=(x: var T, other: not T)`
16:50:57FromDiscord<haxscramper> (edit) "can'" => "can't"
16:52:05FromDiscord<haxscramper> But this is a language design choice I think - `Error: signature for '=' must be proc[T: object](x: var T; y: T)`
16:58:14FromDiscord<codic> oh i see
16:58:20FromDiscord<codic> but @! is possible?
16:58:28FromDiscord<codic> what's `!` doing?
17:00:30FromDiscord<haxscramper> Just as an example, you can create ``func `@@@@@@@@@@@@@`(elements: openarray[T])``if you need
17:00:47FromDiscord<haxscramper> Or ``func `@!`(``
17:02:29FromDiscord<haxscramper> I mean in `let a: seq[int] = @[1,2,3]` only `[1,2,3]` part cannot be changed, but you are free to write your own shorthand prefix operator and then use it `let a: data[T] = @$[a,b,c]`
