01:35:54FromDiscord<snluu> @mratsim https://gist.github.com/snluu/7a95ead2ced436034eaf7270b4f4ed33
01:36:03FromDiscord<snluu> Seems to work fine. Cross check to make sure I'm not "cheating"
01:38:48FromDiscord<snluu> At input = 30, got a "GC Warning: Repeated allocation of very large block (appr. size 2101248)", probably because I'm allocating a new channel everytime
01:38:54FromDiscord<snluu> But other than that, seems to work fine
01:41:14FromDiscord<snluu> This was with just 1 thread. Let me try multiple threads
01:49:23FromDiscord<snluu> with 4 threads, 34 started getting heap warning. the program still finished
02:02:07FromGitter<deech> Dumb question but is `gc:destructors` viral? So if I depend on a library that uses it do I have to?

03:43:18FromDiscord<Xydium> Another dumb question, how do I use system.swap to swap values stored in a sequence inside a ref object passed to a function
03:43:43FromDiscord<snluu> does swap(s[i], s[j]) not work?
03:43:58FromDiscord<Xydium> Type mismatch, expected var T got T
03:44:37FromDiscord<Xydium> `swap(pset.values[i], pset.values[dec partition])`
03:44:53FromDiscord<snluu> is the sequence a var?
03:45:05FromDiscord<Xydium> that would help
03:45:18FromDiscord<snluu> no i mean, can you show me your function signature?
03:45:49FromDiscord<Xydium> the sequence is part of a ref object, so it's not the function signature that matters, it's the type declaration
03:46:03FromDiscord<snluu> where do you get that ref object from?
03:46:10FromDiscord<snluu> var x : ref MyObject?
03:46:15FromDiscord<snluu> or from a function parameter?
03:46:21FromDiscord<Xydium> Function parameter
03:46:27FromDiscord<snluu> is it a var?
03:46:34FromDiscord<Xydium> no
03:46:35FromDiscord<snluu> proc x(y: var ref MyObject)
03:46:37FromDiscord<snluu> you need that
03:47:59FromDiscord<Xydium> `PartSet*[T] = ref object; values: seq[T]; parts: seq[int]`
03:48:08FromDiscord<Xydium> `proc restrict*[T](pset: var PartSet[T], predicate: proc(v: T): bool) =`
03:48:29FromDiscord<Xydium> Just making the param a var doesn't help, the sequence within the type needs to be a var too
03:49:39FromDiscord<Xydium> But that breaks the PartSet constructor, which takes a non-var seq. So I need to convert the passed seq to a var seq
03:50:14FromDiscord<Xydium> `invalid type: 'var seq[int]' in this context: 'PartSet[system.int]' for var`
03:50:53FromDiscord<Xydium> Unless that error is complaining about trying to have a var field in an object
03:51:02FromDiscord<Xydium> But it's in a completely different part of the code
03:52:07FromDiscord<snluu> > Just making the param a var doesn't help, the sequence within the type needs to be a var too
03:52:10FromDiscord<snluu> theres no such thing
03:52:19FromDiscord<Xydium> that explains that
03:54:12FromDiscord<Xydium> `expected <int, int> ... expression 'pset.values[dec partition, 1]' is of type: T`
03:54:18FromDiscord<Xydium> for the swap function
03:54:36FromDiscord<snluu> can you just post your code in a paste?
03:54:40FromDiscord<snluu> how are you calling it?
03:54:50FromDiscord<Xydium> `swap(pset.values[i], pset.values[dec partition])`
03:55:15FromDiscord<Xydium> oh, wait,
03:55:24FromDiscord<Xydium> can't do anything fancy with the dec operator
03:55:30FromDiscord<Xydium> have to move it before the array access
03:55:48FromDiscord<Xydium> `dec partition; swap(..., pset.values[partition])`
03:56:19FromDiscord<Xydium> gone are the days of `while(*s++ != '\0')`
03:56:40FromDiscord<snluu> dec doesn't return anything
03:56:45FromDiscord<snluu> it's a "void"
03:57:21FromDiscord<snluu> > gone are the days of while(*s++ != '\0')
03:57:22FromDiscord<snluu> good

04:55:06FromDiscord<Rika> Macro would be easier to make for that
04:58:57FromDiscord<slymilano> @sealmove: Like this? https://play.nim-lang.org/#ix=25vg
05:01:27sealmoveslymilano: yes, but I don't want to use a long case
05:01:55FromDiscord<slymilano> So you want someone to pass in `"banned"` and have it return `Status.banned`?
05:02:43sealmovehttps://play.nim-lang.org/#ix=25vh
05:02:54sealmoveyup
05:02:58sealmoveexactly
05:03:18sealmovemore specifically in my senario i want to also add a prefix
05:03:27sealmovebecause my enums are not pure
05:03:41FromDiscord<slymilano> Look into ordinals to find the int of your key? ttps://nim-by-example.github.io/types/enums/
05:04:05FromDiscord<slymilano> There's not `Status[myKey]` to my knowledge in Nim, this would be trivial in Javascript
05:04:08FromDiscord<slymilano> There's no `Status[myKey]` to my knowledge in Nim, this would be trivial in Javascript
05:05:21sealmovei just want to make a helper template/macro that accepts strings and add corresponding enums to an array
05:07:18sealmovelike this: https://play.nim-lang.org/#ix=25vi
05:07:52sealmovehttps://play.nim-lang.org/#ix=25vj
05:08:37sealmoveohh
05:08:39sealmovethere is strutils.parseEnum
05:09:11sealmoveawesome
05:11:24FromDiscord<slymilano> Try this? https://play.nim-lang.org/#ix=25vk
05:12:08FromDiscord<slymilano> No need for the template at all: https://play.nim-lang.org/#ix=25vl
05:16:49sealmoveparseEnum solves the problem, yes no need for template: https://play.nim-lang.org/#ix=25vn
05:18:43sealmovegenerics do the trick here

10:12:33FromDiscord<kodkuce> just saw arc went live, gj i personally will w8 a month to try it guessing there are zilion bugs still 🙂
10:13:23FromDiscord<kodkuce> and i want async anyway, async rewrite will be created to support newruntime too i guess, right?
10:14:27FromDiscord<mratsim> It dies on fib 40, they probably choose some stckless fiber implementation but that cannot handle deep recursion
10:15:07FromDiscord<mratsim> it deadlocks on fib 20 as well
10:15:34FromDiscord<mratsim> with 36 threads
10:16:20dwdvJust tried, dlang works fine, but is 6-7x slower than tbb on clang. Mutex is killing the perf I guess. :(
10:17:02FromDiscord<mratsim> AFAIK D only has a threadpool and no load-balancing/scheduler
10:17:16FromDiscord<mratsim> just like Nim and Crystal
10:17:21dwdvYes. Simple task queue.
10:17:58FromDiscord<mratsim> Crystal also deadlocks with fib(10) and 36 threads :/
10:19:01FromDiscord<mratsim> mmm, even with their default of 4 workers it get stucks
10:19:50FromDiscord<mratsim> maybe I'm msising a release option
10:21:02FromDiscord<kodkuce> make nim greate again
10:21:13FromDiscord<mratsim> ah no, I forgot that it blocked waiting for my input lol

10:25:39FromDiscord<Rika> Nim compiler complains about a missing symbol when I try using rlocks
10:25:40FromDiscord<kodkuce> i like nim, just i sounds nice to say it 🙂

12:09:48FromDiscord<Generic> that sounds quite slow, do you make release builds?
12:10:18FromDiscord<mfiano> Yes
12:12:16solitudesffor some reason it uses inheritance and methods, that could be one source of slowness.
12:13:10FromDiscord<mfiano> I see it also doesn't parallelize scanline decoding. No wonder it's slow

14:37:02FromDiscord<kodkuce> its base64 too
14:37:17FromDiscord<kodkuce> i gona use Nim anyway just thinked Nim faster then crystal
14:38:11madpropsis it possible to install a binary with nimble, that places a file in ~/.config ?
14:38:42madpropsa config file i mean, for the program to use
14:46:21kungtotteI think you'd have to profile both languages to track down the difference. It would also be interesting to see how they scale (double and triple the size of the json for example, or increase the complexity of it). Maybe Nim has some initial overhead that goes away as the dataset grows, or it's not great at relatively simple json but handles complex structures better.
14:47:06kungtotteIn the real world, I've had zero performance issues parsing actual JSON with Nim.
14:48:12FromDiscord<mratsim> Nim default json is slow because it allocated a Table at each tree node
14:48:23FromDiscord<mratsim> allocates*
14:48:50FromDiscord<mratsim> both are slow anyway compared to simdjson
14:56:21skrylar[m]isn't that how json is typically processed
14:57:46FromDiscord<mratsim> I don't know but it's costly

15:07:17kungtotteI don't think there's issues really. Allocations are just costly. Maybe it could be rewritten to use fewer allocations. There's bigger fish to fry though I feel :)

15:23:06FromDiscord<mratsim> it's a tradeoff between maintenance, ergonomics and speed
15:23:35FromDiscord<mratsim> the table way is easier to implement, and maintain
15:24:14FromDiscord<mratsim> I think araq's packedjson which only allocates a single heap datastructure AFAIK does not provide the same API as std/json
15:24:57FromDiscord<mratsim> The fastest json parser of the world currently is: https://github.com/lemire/simdjson

15:33:01FromDiscord<Milerius> Fun fact, his library is much more easy to use than simdjson
15:33:12FromDiscord<Milerius> When FFI with D in nim ? :p
15:33:22FromDiscord<mratsim> ask timotheecour
15:33:28FromDiscord<Rika> FFI everything with nim
15:33:46FromDiscord<mratsim> There was the NimBorg probject: https://github.com/micklat/NimBorg
15:33:49FromDiscord<Milerius> Just the fastjson is incrediblefor me
15:33:50FromDiscord<Rika> nim will be known as the language that can easily FFI with all the languages!
15:34:03FromDiscord<Rika> i love that name
15:34:27FromGitter<deech> If I use `gc:destructors` for a library are all users of my API obligated to use it as well?
15:34:32FromDiscord<Milerius> Fastjson should be possible to implement in nim
15:35:08FromDiscord<mratsim> @deech destructors only care about stack objects though
15:35:47FromDiscord<mratsim> so there is no compat issue since all stack objects will eventually follow gc:destructors rules
15:36:11FromGitter<deech> Oh ok, then I don't understand destructors at all. Is this the best documentation? https://nim-lang.org/docs/destructors.html
15:36:28FromDiscord<mratsim> right now it's only seq/strings that change behaviour between nothing and destructors
15:36:38*endragor quit (Remote host closed the connection)
15:36:57FromDiscord<mratsim> yes it's the latest
15:37:09FromDiscord<mratsim> but it doesn't talk to library compat and "in practice"
15:37:30FromDiscord<mratsim> but in short, a library that works under gc:destructors will work under all Nim GCs
15:37:45FromDiscord<mratsim> and you can't use ref objects with just gc:destructors
15:37:46FromGitter<deech> It doesn't seem to directly mention that it's stack-only either.
15:38:00FromDiscord<mratsim> it's stack + seq + strings + pointers
15:38:16FromDiscord<mratsim> gc:none was stack + pointers
15:38:25FromDiscord<mratsim> you can see that as a refinment over gc:none

17:20:42FromGitter<iffy> I'm trying to use libsecret with Nim. I'm trying c2nim on some of the headers, w/o success. For instance, c2nim on https://github.com/GNOME/libsecret/blob/mainline/libsecret/secret-attributes.h fails w/ this error: `(29, 13) Error: token expected: ;`. Any tips?
17:20:44FromDiscord<treeform> I remember some one had a lib or just a set of macros that would parse json into objects directly - without creating intermedia json nodes? Does any one have a link to that? I search forums but nothing...

17:22:27skrylar[m]@iffy you can manually bind functions with `...` by leaving the `...` out of the params and adding a {.vararg.} pragma; i have no idea about `va_args` (i always assumed those didn't work, although they might with emitcs /shrug)
17:22:33FromDiscord<mratsim> it's a plugin for nim-serialization
17:23:35FromDiscord<treeform> Do you know if it wins at JSON benchmark games?
17:24:21FromGitter<iffy> skrylar: It seems like c2nim is dying before it even gets to `...` on the character right after the first `GHashTable *`
17:26:54FromDiscord<Rika> okay, why do we still have tab usage as a syntax error?
17:27:41skrylar[m]because araq has the wrong opinions wrt. indentation :^)
17:28:02FromDiscord<Rika> nice
17:28:13FromDiscord<Rika> i feel like someone's about to get banned...

18:24:56FromDiscord<Fern & Simula (They/Them)> it feels like python vs ruby 2: compiled boogaloo

18:38:46sealmovewhat's the catch for Crystal?
18:38:56FromDiscord<Fern & Simula (They/Them)> but also it doesn't even run on window
18:38:59sealmovefor example for Nim it's native metaprogrammin
18:39:17sealmoveno Windows? eh, that's strange
18:39:38FromDiscord<Fern & Simula (They/Them)> yeah. the main person porting it is now too busy with work to actually port the stdlib to windows
18:40:16FromDiscord<Fern & Simula (They/Them)> crystal also has some decent metaprogramming. i guess the main differences are syntax and OOP

18:58:01FromDiscord<Fern & Simula (They/Them)> let's not please
19:00:29FromDiscord<mratsim> mmm there is no way to count the arity/length of an enum type?
19:01:00skrylar[m]@mratsim more toys https://git.sr.ht/~skrylar/skyhash
19:01:20FromDiscord<Fern & Simula (They/Them)> @mratsim you probably could pretty easily with a macro
19:01:41FromDiscord<mratsim> yeah of course but neither arity or len work out of the box :/
19:01:53FromDiscord<mratsim> @skrylar, your API is called "steaming"
19:02:33skrylar[m]welp.
19:03:02FromGitter<deech> mratsim, I saw something like, `for i in ord(low(MyEnumType)) .. ord(high(MyEnumType)): ...`, not sure if it works for sparse enums though.
19:03:28FromDiscord<mratsim> btw sourcehut is paid only right?
19:03:35Araqmratsim: high(E) - low(E) + 1
19:03:38*narimiran quit (Ping timeout: 240 seconds)
19:03:43FromDiscord<mratsim> my enums are not sparse
19:04:16FromDiscord<mratsim> I guess that's the brute force way :p
19:04:21skrylar[m]@mratsim not quite yet
19:04:57FromGitter<deech> A static iterator like `fieldPairs` would be nice for enums.
19:05:50FromDiscord<Fern & Simula (They/Them)> fieldPairs for enums couldn't be that hard to implement in the stdlib, could it? i feel like that would be extremely useful
19:06:40FromDiscord<mratsim> I only need the length
19:07:18FromDiscord<mratsim> for static you can just do static: for e in low(E) .. high(E):
19:07:26Araqfor i in low(E)..high(E) # close enough IMO
19:07:35FromGitter<deech> Seems do-able, probably just the case that people haven't needed it that much yet ...
19:08:00FromDiscord<mratsim> when I need it I just roll my own
19:08:41FromGitter<deech> Araq, wouldn't work with enums generated from C APIs which often don't go in order.
19:09:41FromDiscord<mratsim> we can't really save them though
19:10:04FromDiscord<mratsim> supporting them would make the iterator have a lot of special cases
19:10:30FromDiscord<mratsim> though we could detect enums with holes at compile-time
19:10:59Araqenums with holes must die
19:11:09Araqsuch an expensive feature

19:18:41FromDiscord<Milerius> do we have a nice demangler for nim function @araq ?
19:18:47FromDiscord<Milerius> Such as c++filt but for nim
19:19:23Yardanico@Milerius why is default target set to C++ though? well, I think it doesn't really matter, but Nim itself still uses C backend as a default
19:19:29Yardanico(that's just a questions though)
19:19:30Araqit's simply .replace("__.*", "")
19:20:03FromDiscord<Milerius> @Yardanico It's not my PR but you can comment if you want
19:20:22FromDiscord<Milerius> any advice will be great
19:21:27AraqC++ generates better code for --gc:arc for the time being

19:47:22lqdev[m]@deech as long as you're on 32-bit, otherwise, you'll need to install manually

19:47:48lqdev[m]for some reason
19:47:59FromGitter<deech> Oh ick. Had no idea.

19:49:37luis_awesome!
19:50:04FromGitter<deech> lqdev, not saying you're wrong, but do you know this from experience because it doesn't mention the limitation in the README.
19:50:24FromGitter<deech> https://github.com/dom96/choosenim/releases
19:50:49Yardanicoas far as I know win 64bit always was one of the main targets for choosenim
19:50:58FromDiscord<mratsim> nop
19:51:16FromDiscord<mratsim> it only downloads 32-bit nim which is extremly annoying
19:51:29Yardanicowow
19:51:54FromGitter<deech> Is this due to some 32-bit dependency issue? The archive seems to have a lot of bundled DLLs.
19:52:41FromDiscord<mratsim> pretty sure it's just that no-one added win64
19:53:14FromGitter<deech> Huh, the website has it: https://nim-lang.org/install_windows.html
19:53:51FromDiscord<mratsim> in my case I just git clone devel, build_all.bat
19:53:55disruptekshashlick will know what's up with that.
19:53:59Araqshashlick added 64 bit support iirc
19:54:01FromDiscord<mratsim> and update the env variable to point to bin
19:54:20Araqfinish.exe can update the environment for you
19:54:27FromDiscord<mratsim> it still download 32-bit, I complained last week wheen I was porting weave to windows
19:54:42FromDiscord<mratsim> from git clone?
19:55:46luis_I dont know if any of you remember a smaill python tool for listing torrents from piratebay called torrench? I just re did it in a simple form in Nim... not sure it is ok to share over github.... I may share using gist, perhaps...
19:55:59Yardanicoluis_: it's totally okay to create a github repo for it :)
19:56:22disruptekmaybe it's a nimarchive build limitation, but i doubt it.
19:56:25YardanicoIt's not like you're actually distributing pirate content, you're just creating a frontend for searching it
19:56:39Yardanico(qbittorrent is open source too, but no one complains that it's used for downloading pirate content :D )
19:57:01luis_yeah, you right... wait a minute.... will upload soonish
19:57:39FromGitter<mratsim> well listing from piratebay is a bit different from listing from a "compatible-torrent website"
19:58:30FromGitter<deech> Oh weird, apparently choosenim hard-codes a 32 bit mingw and uses that to determine the architecture so it will always be 32. Seems like simply changing the url to point to 64-bit mingw should just fix it unless there is a reason to support 32 bit.

20:26:52shashlickAdding support is just to install 64 bit by default and fall back to to 32bit if a flag is specified
20:27:23shashlickFurther, we need to add support to enable both archs to coexist but that's some ways
