01:10:42FromDiscord<Iliketwertles> my nim project to learn shi↵https://github.com/iliketwertles/DPKD
01:11:57FromDiscord<Elegantbeef> So many returns
01:19:08FromDiscord<Iliketwertles> true, i could prob just not use the procs but idk enough yet
01:19:23FromDiscord<huantian> I think beef is suggesting using the procs without returns
01:19:34FromDiscord<huantian> since nim will automatically use the last value you have in your proc as the return value
01:20:21FromDiscord<huantian> sent a code paste, see https://paste.rs/fVn
01:20:24FromDiscord<Elegantbeef> We can even do better

01:20:33FromDiscord<Elegantbeef> https://gdl.space/detubaliba.py is a bit more idiomatic minus me using `colour` instead of the inferior `color`

05:05:01FromDiscord<Rainbow Asteroids> what is the difference between `std/strbasics` and `std/strutils`
05:11:15FromDiscord<Elegantbeef> strbasics works on `openarray[char]`
05:11:33FromDiscord<Elegantbeef> It's also a small package to not bring many dependencies where simple operations are needed iirc
05:16:59FromDiscord<Rainbow Asteroids> interesting
05:21:40*CyberTailor left #nim (Konversation terminated!)
05:31:08FromDiscord<Bung> https://github.com/nim-lang/Nim/pull/20379/checks?check_run_id=8412100779 should I fix the tests or something wrong with my PR ?
05:33:05FromDiscord<Elegantbeef> The errors might be related
05:34:58FromDiscord<Bung> yeah, I know that but dunno whether I should fix the expected output or correct my code
05:38:25FromDiscord<Elegantbeef> Seems the tests might have been wrong?
05:39:40FromDiscord<Elegantbeef> Yea my logic might've been off
05:40:59FromDiscord<Bung> I think I may introduce another branch, seems like sometimes the first error line already show the calling convention
05:41:05FromDiscord<Elegantbeef> omitted calling convention should accept closure or nimcall iirc
05:42:08FromDiscord<Elegantbeef> So inside tproc\_mismatch lines 52, 61, 69, 70, 74 shouldnt error the mismatch on calling conventions
05:42:43FromDiscord<Bung> the existed code shows nimcall -> closure can pass
05:43:02FromDiscord<Elegantbeef> What it errros ` Calling convention mismatch: got '{.nimcall.}', but expected '{.closure.}'.`
05:45:02FromDiscord<Elegantbeef> I think \`\`getProcConvMismatch\` needs a check of https://github.com/nim-lang/Nim/blob/b6bfe38ff5283f77d5e5e78da06d2710bc16afb6/compiler/ast.nim#L574
05:46:39FromDiscord<Bung> I agree , so looks like the code and expected output both need fix
05:46:59FromDiscord<Elegantbeef> No expected seems fine
05:47:39FromDiscord<Elegantbeef> Actually wait... those are correct
05:47:42FromDiscord<Elegantbeef> I misread the code

05:48:48FromDiscord<Elegantbeef> I mean yes it should check if it has an explicitCallingConv
05:49:09FromDiscord<Elegantbeef> And also yes it should error that there is a mismatch of calling convention
05:49:29FromDiscord<Elegantbeef> I dont know how this has hidden for so long but i guess good job accidently revealing my fuckup
05:49:48FromDiscord<Elegantbeef> Luckily it's a minor fuckup
05:50:19FromDiscord<Elegantbeef> and an easy fix of `tfExplicitCallConv in f.flags and f.kind == ccClosure....`
05:50:50FromDiscord<Bung> I guess because tests only covered the first error line, so others are hidden
05:51:04FromDiscord<Elegantbeef> Perhaps?
05:51:29FromDiscord<Elegantbeef> I dont get testament so i dont really know
05:52:47FromDiscord<flywind> In reply to @Bung "I guess because tests": Use `nim check` to get verbose error messages.
05:53:18FromDiscord<Elegantbeef> The test uses nimcheck

05:54:14FromDiscord<Elegantbeef> Bungs changes somehow suddenly revealed and issue with my code
05:54:18FromDiscord<Bung> yeah , it's not about log level.
05:54:47FromDiscord<Bung> I'll fix these
05:54:55FromDiscord<Elegantbeef> Sorry
05:59:09FromDiscord<Bung> no worry
06:03:19FromDiscord<ravinder387> sent a code paste, see https://play.nim-lang.org/#ix=4aNi
06:03:20FromDiscord<ravinder387> invalid indentation
06:04:50FromDiscord<Rika> After the string, you indented one too much
06:06:04FromDiscord<ravinder387> so how to fix it then
06:06:14FromDiscord<Bung> @ElegantBeef `tproc_mismatch.nim(64, 9) Error: type mismatch: got <proc (a: int){.locks: 0.}> but expected 'proc (a: int){.closure, gcsafe.}'↵ Calling convention mismatch: got '{.nimcall.}', but expected '{.closure.}'.` does this right ?
06:06:17FromDiscord<Elegantbeef> Dont use strings
06:06:29FromDiscord<Elegantbeef> Yea
06:07:04FromDiscord<Rika> In reply to @ravinder387 "so how to fix": Dedent the line...
06:08:20FromDiscord<Bung> sent a code paste, see https://play.nim-lang.org/#ix=4aNj
06:08:35FromDiscord<Elegantbeef> should be `notin f.flags`
06:08:53FromDiscord<Elegantbeef> that logic only should apply if you dont have an explicit call convention
06:09:27FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=4aNk
06:09:43FromDiscord<Elegantbeef> I might be misremembering the intention of that code but i think it's above
06:10:20FromDiscord<Elegantbeef> basically in cases the type system or user didnt say `{.nimcall.}` both are accepted
06:12:42FromDiscord<Bung> okay, get it
06:19:39FromDiscord<Bung> sent a code paste, see https://play.nim-lang.org/#ix=4aNp
06:19:49FromDiscord<Bung> these don't have nimcall still not pass ?
06:27:28FromDiscord<Bung> oh they have explicit call convention
06:29:51FromDiscord<Elegantbeef> Yea they get an explicit calling convention when the `proc()` is reified into a variable
06:30:04FromDiscord<Elegantbeef> Hmm did i use 'reified' properly rika knows 😛
06:30:51FromDiscord<Elegantbeef> As a parameter `proc()` is really a typeclass of `proc(){.closure.} or proc(){.nimcall.}` as a variable it has to be concrete so choses the default convention of closure
06:31:45FromDiscord<Elegantbeef> The reason it choses closure by default is that in many cases you'll be making a closure when you use anonymous procedures
06:32:30FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=4aNr
06:34:26FromDiscord<Bung> `teffects1.nim(35, 21) Error: type mismatch: got <proc (x: int): string{.noSideEffect, gcsafe, locks: 0.}> but expected 'MyProcType = proc (x: int): string{.closure.}'↵ Calling convention mismatch: got '{.nimcall.}', but expected '{.closure.}'.`
06:35:04FromDiscord<Bung> what about this case `type↵ MyProcType = proc(x: int): string #{.raises: [ValueError, Defect].}`
06:35:37FromDiscord<Elegantbeef> It's a closure
06:35:54FromDiscord<Elegantbeef> `proc` type definitions default to closure
06:36:45FromDiscord<Elegantbeef> You need to do `proc(x: int): string {.nimcall.}` to force it to nim call
06:37:02FromDiscord<Elegantbeef> You changing the code the way you did seemed to have awaken my changes, which didnt catch this one
06:40:09FromDiscord<Bung> I understand , so only care effect here
06:45:41FromDiscord<Bung> `.\koch.exe temp r .\testament\testament.nim --nim:compiler/nim.exe r .\tests\effects\teffects1.nim`
06:46:00FromDiscord<Bung> sent a code paste, see https://play.nim-lang.org/#ix=4aNv

06:46:39FromDiscord<Elegantbeef> `nim check`
06:49:21FromDiscord<Bung> I can do ` .\koch.exe temp check tests/effects/teffects1.nim` and compare the output by eye, but how to work with testament
06:49:45FromDiscord<Elegantbeef> `.\koch.exe temp r .\testament\testament.nim --nim:compiler/nim.exe check .\tests\effects\teffects1.nim`?
06:51:21FromDiscord<Elegantbeef> Like i said i dont know testament
06:52:13FromDiscord<Bung> hmm, doesn't work , has no check command

07:39:49FromDiscord<Bung> @ElegantBeef saddly , now it break vm https://github.com/nim-lang/Nim/actions/runs/3076295829/jobs/4970351341
07:42:16FromDiscord<Elegantbeef> Hmm is `else: result[0].incl pcmDifferentCallConv` right?
07:43:16FromDiscord<Elegantbeef> If it enters that if statement the call conventions are not a mismatch
07:43:35FromDiscord<Bung> I change `tfExplicitCallConv notin a.flags` to `tfExplicitCallConv notin f.flags` now
07:43:52FromDiscord<Elegantbeef> Ah
07:44:02FromDiscord<Elegantbeef> I didnt even see that, probably the issue
07:44:17FromDiscord<Elegantbeef> Though i still think that else isnt needed, but if it doesnt harm it i guess leave it
07:44:51FromDiscord<Bung> okay, but why there is that error message order issue
07:46:50FromDiscord<Elegantbeef> What order issue
07:47:51FromDiscord<Bung> sent a code paste, see https://play.nim-lang.org/#ix=4aNI
07:48:08FromDiscord<Elegantbeef> Ah not a clue
07:48:54FromDiscord<Bung> sent a code paste, see https://play.nim-lang.org/#ix=4aNJ
07:49:17FromDiscord<Bung> seems like `tfExplicitCallConv notin f.flags` should remove
07:51:43FromDiscord<Elegantbeef> I mean i think it's right
07:52:11FromDiscord<Elegantbeef> This might be an araq question but i'm like 90% certain a parameter marked closure shouldnt accept a nimcall
07:52:52FromDiscord<Bung> what's the side effect if it accpet a nimcall
07:53:29*jmdaemon quit (Ping timeout: 250 seconds)
07:53:38FromDiscord<Bung> since old code allow automatically convert
07:54:13FromDiscord<Elegantbeef> `proc (x: T, y: K): int {.closure.}` is the parameter type afterall
07:54:28FromDiscord<Elegantbeef> sent a code paste, see https://paste.rs/8zo
07:54:37FromDiscord<Elegantbeef> I'm going to shush here since i dont know what's supposed to happen
07:54:37FromDiscord<Elegantbeef> The code explicitly states the call convention then you pass the wrong oen
07:54:39FromDiscord<Elegantbeef> one\
07:54:48FromDiscord<Elegantbeef> That seems like a compile time error, but i guess Nim might create an intermediate closure?
07:55:38FromDiscord<Elegantbeef> > As a special extension, a procedure of the calling convention nimcall can be passed to a parameter that expects a proc of the calling convention closure↵Ah the manual says it's supposed to happen
07:56:29FromDiscord<Elegantbeef> So yes indeed you can just remove the check if it has an explicit calling convention
07:56:35FromDiscord<Elegantbeef> My bad yet again
07:56:42FromDiscord<Bung> so it's definatly should remove, as the manual said

08:12:07FromDiscord<elcritch> haha sorry -- the UI looks the same alas. Though it'll be much better to use now. 😛
08:14:26FromDiscord<elcritch> I'm planning to start writing more widgets soon though. Figuring out this rewrite was a big blocker, but now it's time to actually implement widgets!
08:15:31FromDiscord<Elegantbeef> Dont forget styling!
08:18:46FromDiscord<Elegantbeef> Went to look at your examples and `/tmp/fidgetty/src/fidgetty/themes.nim(38, 64) Error: type mismatch: got <Color, float64>`
08:21:22FromDiscord<elcritch> that's odd, you may need to update the fidget fork? also https://forum.nim-lang.org/t/9476#62228

08:22:09FromDiscord<Elegantbeef> your choosenim example and testdemo
08:22:13FromDiscord<Elegantbeef> Both have the same error
08:24:12FromDiscord<Elegantbeef> Yea i have fidget\_dev#head
08:30:52FromDiscord<elcritch> Ok, let me bump some dependency versions
08:32:16FromDiscord<elcritch> ok just pushed, could you update and try again?
08:36:05FromDiscord<Elegantbeef> You really broke your nimble file now 😛
08:36:24FromDiscord<Elegantbeef> https://github.com/elcritch/fidgetty/blob/main/fidgetty.nimble#L13↵Should be either `@#head` or `>= 1.7.9`
08:36:36FromDiscord<elcritch> 😭
08:37:57FromDiscord<elcritch> Ok, reverted that one. The original problem was not requiring the latest pixie
08:57:57FromDiscord<Elegantbeef> Also you're echoing out the macro
08:58:27FromDiscord<Elegantbeef> Also you're on a mac arent you?

09:02:33FromDiscord<Elegantbeef> Ah `uiScale = 2.0` arguably should be inferred by the DPI scaling on the OS I imagine

12:09:58FromDiscord<Yardanico> In reply to @Goel "So to escape a": just do `\\` ?
12:10:27FromDiscord<Goel> But i need to check the single char '\'
12:10:39FromDiscord<Goel> (edit) "'\'" => "`'\'`"
12:10:43FromDiscord<Yardanico> `\\` is a single char
12:10:45FromDiscord<Yardanico> without `r`
12:10:48FromDiscord<Yardanico> because you escape the `\`
12:11:12FromDiscord<Goel> This also works i think, i need to try: `'\''`
12:11:21FromDiscord<Yardanico> yes that'll work as well
12:11:30FromDiscord<Yardanico> `\` is used for escaping stuff by default unless you use `r`
12:11:41FromDiscord<Yardanico> so to write `\` you have to write `\\` in strings

12:40:10FromDiscord<Forest [She/Her]> name
12:40:38FromDiscord<Rika> In reply to @Goel "Why this doesn't output": Because the second character is the escape code \b, you didn’t make it raw with r
12:40:54FromDiscord<Rika> R is for raw strings and characters aren’t strings so
12:41:08FromDiscord<Rika> You can’t use it on characters
12:44:03FromDiscord<Goel> Even if i change str to be `= r"a\b"` still don't work, that sucks. So i simply can't check for the occurce of `\` char inside my string?
12:44:39FromDiscord<Rika> Oh no
12:44:44FromDiscord<Rika> You’re checking for '
12:44:44FromDiscord<Goel> (edit) "occurce" => "occurence"
12:44:46FromDiscord<Rika> Not \
12:44:52FromDiscord<Rika> I misread too
12:44:57FromDiscord<Goel> How?
12:45:50FromDiscord<Rika> `'\''` should be `'\\'`
13:00:34FromDiscord<Forest [She/Her]> Hey so i'm doing bit operation related stuff rn, and i have some feedback for improving the page for it, is there a specific place or should i dump it here?

13:52:00FromDiscord<Forest [She/Her]> Alright then
13:54:23FromDiscord<Forest [She/Her]> When porting examples or pseudocode to Nim, i was a bit confused since Nim doesn't have bitwise operators and instead just uses method names, what confused me the most in the example i was reading from wiki.vg (I'm implementing an MC Java Edition server) was `val |= a`, since the equivalent in Nim is `val = bitor[int](val, a)`
13:55:20FromDiscord<Forest [She/Her]> It would be useful to have the equivalent operator symbols just named in the docs, so examples become a bit easier to follow
13:55:38FromDiscord<Yardanico> but it is there

17:00:37FromDiscord<huantian> In reply to @sOkam! "what's the difference between": I think it only matters if you use addr?
17:01:03FromDiscord<huantian> If the type is passed transparently via ref to a proc, that’s just my guess tho
17:07:21FromDiscord<sOkam!> In reply to @huantian "I think it only": its for gc:none, so i think it could be relevant then

18:57:30FromDiscord<Phil> Wouldn't that make it impossible to create an array which afaik relies on size being known at compiletime?
18:57:42FromDiscord<Forest [She/Her]> Oh probably not lmao
18:59:33FromDiscord<Phil> Like, array size is something that is part of the type annotation, thus it needs defined size at compiletime.↵So I think you're stuck with seq

21:10:39FromDiscord<Elegantbeef> I dont know why you're attempting to print out a float in scientific notation
21:10:42FromDiscord<Elegantbeef> You only need to be able to import these, output a normal float literal

22:43:14FromDiscord<Generic> In reply to @retkid "are bitwise ops faster": math as in operations from math.nim or math as in arithmetic operations?
22:43:24FromDiscord<Generic> because bitwise operations are fast

23:24:03FromDiscord<Elegantbeef> Depending what you're doing perhaps simd might be what you need
23:24:23FromDiscord<Generic> most SIMD instruction sets don't have integer division instructions
23:24:40FromDiscord<Generic> only AVX 512 and SVE iirc have got those
23:25:54FromDiscord<Elegantbeef> Ah I only roughly know how simd works so no clue what extensions actually provide 😄
23:26:28FromDiscord<Generic> ok apparently not even AVX 512 has it
23:26:36FromDiscord<Elegantbeef> Ah shame
23:27:43FromDiscord<Generic> though double precision integers can hold all values 32-bit integer can
23:27:55FromDiscord<Generic> (edit) "integers" => "floats"
23:28:09FromDiscord<Generic> so you can covert to that and use fp division
23:28:53FromDiscord<Generic> not ideal, but probably the fastest way to do it
