00:00:19FromDiscord<Technisha Circuit> T: So, any compiled languages that can make DLLs or .so files out of libraries should theoretically be usable in Nim, right?
00:00:55FromDiscord<Elegant Beef> Well the C# .dlls run on the C# runtime
00:01:06FromDiscord<Elegant Beef> They are not system libraries
00:01:24FromDiscord<Elegant Beef> For instance you can run C# .dlls on linux using dotnet core
00:01:33FromDiscord<Technisha Circuit> Oh okay
00:01:49FromDiscord<Elegant Beef> It's an annoying overlap of extensions
00:01:54FromDiscord<Technisha Circuit> Big oof
00:02:19FromDiscord<Technisha Circuit> So C# DLLs and .so files aren't usable in Nim
00:02:24FromDiscord<Elegant Beef> C# doesnt make .so
00:02:30FromDiscord<Elegant Beef> It only makes .dlls
00:02:36FromDiscord<Elegant Beef> Which are usable through dotnet core
00:02:43FromDiscord<Elegant Beef> Or mono
00:03:27FromDiscord<Technisha Circuit> O
00:03:45FromDiscord<Elegant Beef> like if you make a dotnetcore CLI application on linux it'll output a runnable .dll
00:03:56FromDiscord<Technisha Circuit> Oh okay :p
00:04:00FromDiscord<Elegant Beef> you do `dotnet ./*.dll`
00:04:10FromDiscord<Technisha Circuit> That's weird imo
00:04:17FromDiscord<Rika> its dot net
00:04:25FromDiscord<Rika> what do you expect, a sane interface for linux?
00:04:35FromDiscord<Technisha Circuit> :p
00:04:45FromDiscord<Elegant Beef> Well the weird part is the extension overlap
00:04:50FromDiscord<Technisha Circuit> Wdym?
00:05:00FromDiscord<Rika> im thinking of making a more sane redis wrapper api but i cant think of a good one so ill prolly just leave it to another time
00:05:03FromDiscord<Elegant Beef> They're both .dlls but cant be used reversibly
00:05:49FromDiscord<Technisha Circuit> Kinda weird, dotnet, coding in general is weird
00:06:00FromDiscord<Technisha Circuit> (edit) 'dotnet,' => 'dotnet is weird,'
00:06:20FromDiscord<Rika> programmers are not sane
00:06:21FromDiscord<Elegant Beef> Like a C# .dll when imported to your C# project works like C# code written anywhere, no manual bindings nothing it's just parsed as C# code
00:06:26FromDiscord<Rika> therefore our work is not sane
00:06:27FromDiscord<Technisha Circuit> That's true
00:06:36FromDiscord<Technisha Circuit> O
00:06:50FromDiscord<Elegant Beef> It'd have taken point 3 seconds to name it a `.dllsharp`
00:06:57FromDiscord<Elegant Beef> Or something less redundant
00:07:06FromDiscord<Technisha Circuit> So basically C# is a weird language
00:07:15FromDiscord<Elegant Beef> Well it's java, but by microsoft
00:07:29FromDiscord<Technisha Circuit> Oh okay, that's worse
00:08:00FromDiscord<Elegant Beef> Well there is the mono runtime
00:08:05FromDiscord<Technisha Circuit> How difficult would it be for me to make a crappy Ruby backend for Nim? :GWchinaSakuraThinking:
00:08:06FromDiscord<Rika> net core
00:08:09FromDiscord<Elegant Beef> Which is the openjre equivlent i guess
00:08:16FromDiscord<Technisha Circuit> I'm just curious again :P
00:08:25FromDiscord<Technisha Circuit> > Which is the openjre equivlent i guess↵Nice
00:08:26FromDiscord<Elegant Beef> Man, why dont you just work in nim 😄
00:08:44FromDiscord<Technisha Circuit> Because it's fun messing with multiple languages at once hahaha
00:08:59FromDiscord<Rika> id prolly end myself if i did what you do
00:09:00FromDiscord<Elegant Beef> I can only agree when there is a GPU involved
00:09:06FromDiscord<Technisha Circuit> And Rika said it themself,↵> programmers are not sane↵> therefore our work is not sane
00:09:11FromDiscord<Elegant Beef> Program on a phone and want multiple langauges? Rika
00:09:15FromDiscord<Rika> technica
00:09:16FromDiscord<Rika> (edit) 'technica' => 'technicae'
00:09:22FromDiscord<Technisha Circuit> :P
00:09:25FromDiscord<Rika> you are the least sane amongst us right now
00:09:34FromDiscord<Technisha Circuit> Not surprised xD
00:09:50FromDiscord<Elegant Beef> Like if you want to use other languages, i say use them, unless you really need some cross langauge support
00:09:53FromDiscord<Rika> you're less sane than if you subtracted my sanity with beef's or vice versa
00:09:55FromDiscord<Technisha Circuit> :GWchinaNayuSmile:
00:10:15FromDiscord<Elegant Beef> Well if you subtract my sanity from yours it's still your sanity
00:10:20FromDiscord<Elegant Beef> 100-0 = 100
00:10:46FromDiscord<Rika> youre telling me tech has negative sanity?
00:10:46FromDiscord<Elegant Beef> Dont bring up your or statement
00:10:47FromDiscord<Rika> damn
00:11:02FromDiscord<Technisha Circuit> > Like if you want to use other languages, i say use them, unless you really need some cross langauge support↵I still love Nim and I'm starting to use it way more then Python, but messing with multiple langs is fun
00:11:44FromDiscord<Technisha Circuit> > youre telling me tech has negative sanity?↵@Rika i do, i have negative infinity sanity
00:11:52FromDiscord<Elegant Beef> I only really know C#/HLSL/Nim, so i dont know how it is
00:11:58FromDiscord<Technisha Circuit> :GWomoRaphiWink:
00:12:10FromDiscord<Elegant Beef> I dont touch other languages cause i tend to dislike them for various reasons
00:12:18FromDiscord<Technisha Circuit> Oh?
00:12:36FromDiscord<Technisha Circuit> Also, do you prefer braces or whitespace-based programming?
00:12:40FromDiscord<Elegant Beef> Indifferent
00:12:45FromDiscord<Elegant Beef> I prefer clean code
00:12:47FromDiscord<Elegant Beef> And tabs
00:12:48FromDiscord<Technisha Circuit> Cool
00:12:54FromDiscord<Technisha Circuit> ONot cool
00:12:59FromDiscord<Technisha Circuit> (edit) 'ONot' => 'Not'
00:12:59FromDiscord<Rika> lmao
00:13:07FromDiscord<Technisha Circuit> Tabs are a pain-
00:13:20FromDiscord<Technisha Circuit> Just make tabs into 4 spaces by default-
00:13:21FromDiscord<Elegant Beef> I think just like everyone customizes their editor they should be able to customize the rendering of their text
00:13:29FromDiscord<Elegant Beef> I do for nim just to be in a middle ground
00:13:36FromDiscord<Technisha Circuit> :P
00:13:48FromDiscord<Elegant Beef> But as i've said before i use big old indents of 8 in C#, and like it as it's very clear indent
00:14:04FromDiscord<Rika> until everyone makes tabs have a sane default im still not supporting tabs
00:14:15FromDiscord<Technisha Circuit> :P
00:14:20FromDiscord<Technisha Circuit> Tabs are stupid-
00:14:21FromDiscord<Elegant Beef> I mean i only use vscode so idk what doesnt have a sane default
00:14:24FromDiscord<Elegant Beef> They really arent
00:14:27FromDiscord<Elegant Beef> The lack of support is
00:14:33FromDiscord<Rika> notepad, literally every browser, etc
00:14:36FromDiscord<Rika> nano
00:14:48FromDiscord<Elegant Beef> How is it anymore stupid than being able to customize your editor
00:14:52FromDiscord<Rika> any standard text editor i assume
00:14:57FromDiscord<Technisha Circuit> Maybe Nim should accept both, but just change tabs to spaces by default
00:15:10FromDiscord<Elegant Beef> Well no Araq openly said he wants one standard
00:15:16FromDiscord<Rika> i think nim should be fine with either and error out when both are used
00:15:24FromDiscord<Elegant Beef> Well per one module
00:15:33FromDiscord<Elegant Beef> Each module is solved on a module by module basis
00:15:39FromDiscord<Elegant Beef> That could work
00:15:50FromDiscord<Rika> but i still dont like tabs 😛
00:16:00FromDiscord<Elegant Beef> I mean you dont dislike tabs, you dislike that they arent supported
00:16:12FromDiscord<Elegant Beef> If they were supported and customized everywhere would you still be opposed to them?
00:16:13FromDiscord<Rika> its really just the shitty default size
00:16:47FromDiscord<Elegant Beef> I think a majority of people agree that in modern editors being able to look at code the way you want to is beneficial, since it doesnt change the underlying code
00:17:05FromDiscord<Elegant Beef> Spaces hardcode that into the file, imagine if the font used was hardcoded in the file
00:17:09FromDiscord<Rika> also am i the only one who doesnt use either indent guides or indent highlights
00:17:26FromDiscord<Elegant Beef> You mean colourful indents?
00:17:40FromDiscord<Technisha Circuit> Just add```nim↵#? replace(sub=" ", by=" ")```to the start of your file to use tabs, just change by to be however many spaces you want
00:17:43FromDiscord<Elegant Beef> Where each stage gets a colour, or just visiblle whitespace?
00:17:44FromDiscord<Rika> indent guides as in the lines, and highlights as in the colored in indents
00:17:53FromDiscord<Technisha Circuit> And replace sub with an actual tab
00:18:00FromDiscord<Elegant Beef> Yes i know that exists but i dont like it
00:18:15FromDiscord<Technisha Circuit> Oh? Why not?
00:18:18FromDiscord<Rika> https://media.discordapp.net/attachments/371759389889003532/719706906519666778/unknown.png
00:18:21FromDiscord<Rika> no guides
00:18:33FromDiscord<Rika> theyre kinda too distracting for me
00:18:39FromDiscord<Elegant Beef> Cause the source relies on a single line to be useable
00:18:47FromDiscord<Elegant Beef> I only use visible whitespace
00:18:51FromDiscord<Technisha Circuit> Fair enough
00:18:52FromDiscord<Elegant Beef> Also cause it's against conventions
00:18:58FromDiscord<exelotl> Rainbow indents are nice, but people who use rainbow indents and strip-trailing-whitespace are mad
00:19:00FromDiscord<Technisha Circuit> :P
00:19:20FromDiscord<exelotl> Like what's the point in rainbow indents full of holes
00:19:30FromDiscord<Elegant Beef> Forgot i changed my vscode theme yesterday, but anyway↵This is all i got https://media.discordapp.net/attachments/371759389889003532/719707207922614392/unknown.png
00:19:33FromDiscord<Rika> i use only strip trailing
00:19:59FromDiscord<Elegant Beef> Guess i have indent levels, dont notice it until i screenshot
00:20:11FromDiscord<exelotl> That's a nice theme beef, what is it?
00:20:37FromDiscord<Technisha Circuit> Winux?

07:32:03PMunchAha, so in C code iterators are actual objects, not pointers
07:32:25PMunchBut they contain two pointers, so copying the object would still refer you to the same iterator.
07:33:30PMunchSo I guess the only way to create an identifier for iterators would be to write it into the compiler..
07:33:44PMunchOr...
07:37:33PMunchI can cast it to an array of bytes two pointers long..
07:37:40PMunchAnd hash that

10:01:26russellb1Hi folks
10:01:53russellb1How do I return an array from a procedure? Am I trying something sane?!
10:02:37FromDiscord<djazz> Zevv, nice read, thanks!
10:03:10Zevvyw
10:03:45narimiranrussellb1: without looking at your code, i'm guessing you really need a `seq`, not an array
10:05:05russellb1@narimran: hhmmm
10:05:08russellb1I see
10:07:16*adnan338 joined #nim
10:07:54krux02russellb1, depends
10:08:13krux02russellb1, you can return a seq, an array, an openarray
10:08:26krux02array is fixed size. Keep that in mind.
10:09:01krux02also, do you want a copy of data, or you you want to reference data somewhere else.
10:16:09FromDiscord<Zed> does anyone have any nim multithreading examples?
10:19:20FromDiscord<Recruit_main707> krux02: can you return an openArray???
10:19:31FromDiscord<Shucks> https://play.nim-lang.org/#ix=2oI1 This is very inefficient. How would I `toHex` the whole byte sequence at once?
10:19:44krux02Recruit_main707: yes you can
10:20:00FromDiscord<Recruit_main707> how?
10:20:04krux02you can return subarrays as open array as well
10:20:16krux02generally with the `toOpenarray` helper procs
10:20:17FromDiscord<Recruit_main707> do you have an example?
10:20:25krux02I think there are examples
10:20:26FromDiscord<Recruit_main707> i see
10:20:52FromDiscord<Recruit_main707> and you specify the returning type of the proc as AopenArray[type]?
10:22:16russellb1@krux02: I want reference data
10:22:37krux02russellb1, then openarray is probably the best option
10:22:55krux02Recruit_main707: yes

10:23:16russellb1@krux02: How easy to pass a reference to an external C program as a pointer?
10:23:22russellb1Or how possible?
10:23:39krux02super easy
10:23:51krux02unsafeAddr is your friend
10:24:05PMunch@Zed, what are you looking for?
10:24:08krux02allows you to get the addr of everything
10:25:17FromDiscord<Recruit_main707> i always thought unsafeAddr is very long
10:25:45krux02then rename it with a template
10:26:10krux02template myUnsafeAddress(argument: untyped): untyped = unsafeAddr(argument)
10:26:30krux02or better make it typed
10:26:40krux02template myUnsafeAddress(argument: typed): untyped = unsafeAddr(argument)
10:26:57PMunchBut now you made it longer krux02! /s
10:27:14FromDiscord<Zed> PMunch, just something more then what's in the docs
10:27:23krux02yes, making it shorter is a task for the reader

11:15:17*kenran quit (Ping timeout: 265 seconds)
11:15:22gourhow does it compare with e.g. NiGUI for real work...
11:16:19Yardanicogour: you might also be interested in https://github.com/StefanSalewski/gintro
11:17:41gourYardanico: i plan to work on multi-platform app and way too often i'm told that GTK & Mac OS do not fit together well...
11:17:52gouri'm on linux however...
11:17:56Yardanicowell nigui will only really work for simple apps
11:18:09Yardanicoalso GTK on macOS is fine but you probably won't have that "native" look
11:18:16Yardaniconigui on macos uses GTK too fwiw
11:18:42gourYardanico: yes, but there is plan to add native macos support. is gintro more mature/complete?
11:19:04Yardanicogour: well gintro is much more complete since it's a binding to all of GTK 3 (and GTK 4 too)
11:19:25gourYardanico: only one contributor for gintro...
11:19:36Yardanicoand mostly one contributor to NiGUi too
11:19:48Yardanicoand macos support is in the "planned" status for at least 3 years in nigui
11:20:49YardanicoIMO gintro is currently the best choice for advanced GUIs in Nim
11:20:55gourYardanico: ohh...which GUIs for Nim are using GC saving the user to handle memory manually? i know that gintro does it, not sure about nimx, nigui...
11:20:55Yardanicofor simpler stuff nigui will be enough
11:21:05Yardanicogour: nigui does it as well
11:21:09Yardaniconimx too
11:21:15Yardaniconimx doesn't use any native frameworks at all though
11:21:18Yardanicoit uses OpenGL
11:21:29Yardanicowell, also webgl for js backend
11:21:50gourYardanico: i do not plan toy app...thinking about it for quite some time, but due to various reasons was not able to work on it earlier...and using nim seems as better idea than python
11:22:23Yardanicowell as I said before for more advanced GUIs you might have luck with gintro since there are some tutorials about GTK and stuff, and gintro itself has a lot of examples
11:22:28gourfor some reason, nimx does not seems ok for me, althoug it even target android...
11:22:40Yardaniconimx is pretty advanced too, but it lacks documentation a bit
11:22:48Yardanicogour: define "does not seem ok" :P
11:22:58PMunchgoul, well I plan to make sure that it continues to run on the latest version of Nim. And to fix any bugs that pop up. But it's mostly just a wrapper around wxWidgets with the addition of a fairly straight forward DSL, haven't really planned any more features. But I'll gladly accept PRs if they are well made
11:23:46gourYardanico: well, just a feeling...is Stefan visiting this place?
11:24:26gourPMunch: does it take care of memory management or it has to be done manually?
11:24:33Yardanicoyou might have better luck asking about gintro on the forum, but yeah, they're there sometimes
11:24:34Yardanico!seen StefanSalewski
11:24:34disbotStefanSalewski never seen.
11:24:36Yardanicolol
11:24:51Yardanicoseems like he doesn't really visit IRC nowadays
11:24:59Yardanicoso yeah, ask on the forum (or in gintro issues) about gintro

11:26:22gourif i need to bind 3rd party C library which i'd include in sources, which build system would you recommend for nim or it can be done with nim's tools only?
11:26:36Yardanicoyou can define any tasks in .nimble
11:26:42PMunchgour, well it uses the WxWidgets memory model, so I guess you might have to do some manual stuff there
11:26:48PMunchDon't remember TBH
11:26:58goureven bulding of manual written in e.g. rst?
11:27:09gourPMunch: ok
11:27:17PMunchYou can use Nim directly, possibly with something like nimterop
11:28:36gourPMunch: with nimterop one can also provide soe called thick (aka more Nim) bindings instead of just wrapper over C API?
11:28:56Yardanicoof course, yes
11:29:12Yardanicoyou just create idiomatic nim procedures which call native C functions
11:29:20*gour thumbs up
11:29:28PMunchYeah, what you typically do is use something like that to create the thin wrapper and then build a thick wrapper on top

12:42:36FromDiscord<djazz> running into another overloading issue again. In my Response object type I have `status*: HttpCode` and if I want to be able to set an int to it I tried to do `proc ´status=´*(this: Response, code: int) = this.status = HttpCode(code)` (i flipped the ´ here so it would highlight) but I still get same error `type mismatch: got <int literal(304)> but expected 'HttpCode = distinct range 0..599(int)'`
12:43:23FromDiscord<djazz> if I remove the * from the type definition it works because then it doesnt see the property, but I would have to write another setter and more getters
12:43:28FromDiscord<djazz> or rename the prop
12:46:50FromDiscord<djazz> seems like * doesnt matter if i use it in same file
12:46:55FromDiscord<djazz> here is an example https://play.nim-lang.org/#ix=2oIw
12:49:23ldleworkcolorize.nim(13, 15) Error: undeclared identifier: 'fggreen'

12:49:51ldleworkoh nm
12:52:16PMunchAny reason you're not using termstyles?
12:53:05FromDiscord<willyboar> 🙂
12:54:05FromDiscord<djazz> the manual at https://nim-lang.org/docs/manual.html#procedures-properties says "the builtin dot access is preferred if it is available" but I thought that was only inside the proc, not for the whole module?
12:55:28FromDiscord<djazz> seems like i would have to make setters and getters
12:57:58FromDiscord<mratsim> it's in the module, there is no way to know which proc are the blesed accessors otherwise
12:59:32FromDiscord<djazz> looks like i can't have two getters either, "overloaded 'status' leads to ambiguous calls"
13:03:20FromDiscord<djazz> oh well, guess I'll have the users of the module use HttpCode instead of passing numbers

13:16:36FromDiscord<djazz> a http code should be a symbol (or in nim's case, distinct type)

13:16:46FromDiscord<djazz> youh shouldnt do math on them
13:16:46alehander92it can be enum
13:16:58alehander92but i agree this might be more confusing, so distinct should be fine
13:17:09FromDiscord<djazz> there are constants, e.g. Http200
13:17:17alehander92yeah
13:17:28FromDiscord<djazz> so the user have to do ctx.status = Http404
13:17:44FromDiscord<djazz> and to get int, just do ctx.status.int

18:50:48*crem quit (Read error: Connection reset by peer)
18:53:32FromDiscord<mratsim> callback: proc(env: pointer) {.nimcall, gcsafe.}
18:53:45FromDiscord<Generic> inline assembler in general is a step child
18:54:02FromDiscord<Generic> I know it's not meant to be used for more than a few lines
18:54:27FromDiscord<Generic> but once you jump into dedicated assembler files interop with C++ becomes horrible
18:54:50FromDiscord<mratsim> for bigint or cryptography you are basically required to drop down in assembler
18:55:37FromDiscord<Generic> I know for the carry stuff, though from my experience doesn't this mess totally with the compiler's scheduling abilities?
18:55:43*crem joined #nim
18:56:18FromDiscord<Generic> this is a bit of a curse of gcc's implementation of neon intrinsics
18:56:39FromDiscord<Generic> some of them are implemented via inline assembler instead of via builtins
18:57:01FromDiscord<mratsim> assembler yes, inline assembler no
18:57:29FromDiscord<mratsim> gcc can elide or choose registers or even whether it puts them in memory or register if you tag them with +rm
18:57:54FromDiscord<mratsim> the only annoying thing is that GCC and Clang have different extended assembler convention for accesses with offsets
18:58:21FromDiscord<Generic> hm, my problem was that sooner or later I reached the maximum amount of operands
18:58:40FromDiscord<mratsim> I tried to build a compiler for inline assembler as a proof of concept: https://github.com/mratsim/constantine/blob/master/constantine/primitives/research/addcarry_subborrow_compiler.nim#L43-L61
18:59:04FromDiscord<mratsim> in GCC for a 8 byte displacement I would use 8+%[b]
18:59:11FromDiscord<mratsim> in Clang 8%[b]
18:59:36FromDiscord<Generic> interesting, though Nim is better of than C++ anyway
18:59:37FromDiscord<mratsim> otherwise you get super weird and unhelpful errors
19:00:31FromDiscord<mratsim> also if you tag a proc {.inline.} Clang will just bail out with that syntax
19:01:04FromDiscord<mratsim> If I expand on that I will pass all array indices as arguments instead of playing with array offsets
19:01:32FromDiscord<mratsim> that might lead to 50 arguments when iterating on 2 arrays with 20 elements for an addition but oh well ...
19:01:56FromDiscord<mratsim> someone is trying to pass 3M arguments to a function since a month ago 😉
19:05:12FromDiscord<Generic> I wonder if we could in theory write better neon intrinsics in Nim
19:05:18FromDiscord<Generic> with some kind of higher level assembler dsl
19:05:24FromDiscord<mratsim> Sure
19:05:48FromDiscord<Generic> (alternatively you could just use clang)
19:05:58FromDiscord<mratsim> it's a bit limited
19:06:07FromDiscord<mratsim> you don't have easy access to shuffle for example
19:06:28FromDiscord<mratsim> but this matrix multiplication code reaches the speed of decades old BLAS code: https://github.com/numforge/laser/blob/master/laser/primitives/matrix_multiplication/gemm_ukernel_sse2.nim
19:06:40FromDiscord<mratsim> and adding support for new instructions and fallback is very easy
19:06:50FromDiscord<mratsim> https://github.com/numforge/laser/blob/master/laser/primitives/matrix_multiplication/gemm_ukernel_avx512.nim#L40-L74
19:07:18FromDiscord<mratsim> for extending with neon the hardest would be runtime detection of Neon support
19:08:13FromDiscord<Generic> I'm not super familar with sse, though from the surface I prefer neon simply for it's interleaved/deinterleaved store
19:09:21FromDiscord<mratsim> well it's just that if neon has load, store, addition, multiplication, I just need to put the function name in there and voila neon support
19:09:59FromDiscord<mratsim> and it would be competitive or even faster than han optimized ASM kernels
19:10:27FromDiscord<mratsim> I can't beat Intel, but ARm didn't put as much work in their linear algebra routines
19:10:40FromDiscord<mratsim> and I can beat OpenBLAS

19:15:02FromDiscord<mratsim> lack of time
19:15:16FromDiscord<mratsim> I have to whip up my Raspberry Pi to test them
19:15:49FromDiscord<Generic> hm, I imagine it would be (atleast for the matrix mul) pretty straightforward
19:16:02FromDiscord<Generic> though this is really not field
19:17:29FromDiscord<Generic> the code for float ops generated from neon intrinsics a lot less quirky than integer
19:17:50Yardanicoif you have a relatively modern android phone you can install termux and run a SSH server here, and connect from the computer (via wifi or you can also use termux over adb)
19:18:19Yardanicoand then test in termux (since it's a linux environment for android including a C compiler)
19:18:39Yardanicomost modern phones (on android) supports tons of ARM extensions
19:19:44FromDiscord<Generic> pretty much any aarch64 processor supports neon

20:09:13fredrikhrOn linux, where does nimble put the nimcache when calling install?
20:09:22disruptek~nimcache
20:09:22disbotnimcache: 11the best way to figure out where it is located is to specify that location with --nimcache -- disruptek
20:10:16Yardanicofredrikhr: nim on most *nix OSes uses ~/.cache/nim
20:10:20Yardanico~ being your home folder
20:10:21disbotno footnotes for ``. 🙁
20:10:43fredrikhrdisruptek, Yardanico, and when invoking nimble I do that how? `-p --nimcache:/path/to/somewhere` ?
20:10:54Yardanicoas I said you can just look into ~/.cache/nim :P
20:13:35fredrikhrSo a docker container running nimble would simply delete .cache, right?
20:13:42Yardanicowdym?
20:13:56Yardanicoit won't delete anything, why would it
20:14:05Yardanicousers in docker containers have their own homedir
20:14:05disrupteki dunno, i don't use nimble.
20:14:07Yardanicousually
20:14:32disruptekyou can delete the .cache thusly, or just cause nim to ignore it with -f to the compiler.
20:14:36fredrikhrYardanico, because of the size of the layers, you want each layer to be as small as possible, you don't actually need the cache
20:14:40disruptekie. force rebuild.
20:15:03disruptekfredrikhr: are you putting a compiler under a lambda layer?
20:15:11disruptekunder/into
20:15:27fredrikhrdisruptek, no, I am making myself a devcontainer
20:15:55disruptekah, well you don't need the .cache but it might be worthwhile if you want to avoid recompiling stuff.
20:16:02Yardanicodisruptek: you can't disable it anyway
20:16:11Yardanicosince nim needs a place to store .c files temporarily :P
20:16:17Yardanicowell you can change it to /tmp for example lol
20:16:41disruptekhe's talking about freezing an image, not removing .cache ability.
20:16:46fredrikhrdisruptek, yeah I know, but when I build the container, I don't need the cache for the intermediaries, so I'd delete them
20:16:49disruptekhe wants it to be as small as possible.
20:17:03Yardanicowell just delete the cache after building then
20:17:14Yardanicorm -rf ~/.cache/nim and done
20:17:49fredrikhrYardanico, that was the plan, hence my original question: Where is it. You answered it: in ~/.cache/nim, and yes there I found it
20:18:03fredrikhradding the rm step in my dockerfile now :)
20:18:04disruptekfor example, nigel reuses cache so that a subsequent test run can be accelerated because dependencies are already compiled.
20:18:32disruptekit just bakes it into a new immutable layer.
20:19:18fredrikhrAnd I noticed that the linux binaries that I download from https://nim-lang.org/download/nim-$NIM_VERSION-linux_x64.tar.xz contain the c_code directory for the compiler, I don't need that either IIRC?
20:19:40disrupteknot once you've built it, no.
20:20:01disruptekit's weird that it'd incude csources.
20:20:17disrupteki'll defer to someone that uses binaries.

20:22:36fredrikhrYardanico, I don't build the compiler at all (too much hazzle), I simply download the pre-built binaries from the nim-lang website
20:22:42Yardanicoah okay

20:29:24FromDiscord<Rika> @Shucks in `callback: proc()`, you must indicate argument type (and name but the name can be anything)
20:29:32FromDiscord<Rika> no you cannot have this vary
20:29:35FromDiscord<mratsim> @Shucks: callback with arguments - https://github.com/mratsim/Arraymancer/blob/master/src/autograd/autograd_common.nim#L85-L96↵calling it: https://github.com/mratsim/Arraymancer/blob/master/src/autograd/autograd_common.nim#L237
20:29:46fredrikhrwoah... Deleting the nim intermediaries shaved off 128MB of data :O
20:29:47Yardanico@Rika that's what i said :P
20:30:09fredrikhri.e. cache and nim c_code
20:30:40FromDiscord<mratsim> other example↵callback with argument: https://github.com/mratsim/weave/blob/master/weave/datatypes/sync_types.nim#L32↵calling it: https://github.com/mratsim/weave/blob/master/weave/workers.nim#L41
20:31:52FromDiscord<mratsim> Note that Weave serializes the argument in a data field and uses a `pointer` (untyped) and cast the callback to a generic proc(env: pointer) type to support any proc via type erasure
20:32:10FromDiscord<Shucks> Thanks gonna check that out. ↵> you just add an argument to that proc type, although it should always be the same↵@Yardanico[IRC]#0000 That makes sense but I want to be flexible with the arg type and amount of arguments
20:32:22Yardanicowell that's much harder
20:32:51FromDiscord<mratsim> Then you need to use the same strategy as I use in Weave
20:32:55Yardanicopointers? :P
20:33:08FromDiscord<mratsim> poor man's closure
20:33:22FromDiscord<mratsim> a data type that is large enough to support all kinds of arguments
20:33:29FromDiscord<mratsim> (I use 144 bytes)
20:33:43FromDiscord<mratsim> ah but you don't need closure
20:34:10FromDiscord<mratsim> store all proc as proc(env: pointer) and cast them to the correct type just before use
20:34:48FromDiscord<mratsim> or store the argument in an array before call and then take the address of that array and pass it to the proc
20:44:50FromDiscord<Shucks> https://play.nim-lang.org/#ix=2oLw
20:44:56FromDiscord<Shucks> guess i've found a hacky solution
20:45:38Yardanicoyeah, that's closures :P
20:45:51Yardanicoah wait no

21:10:56FromDiscord<él liquido> is it because **rust**, perhaps?

21:11:31FromDiscord<él liquido> well theoretically we have `asm` but it's lame

21:30:35Guest16946i am looking for a simpler way to set a configuration structure when coding for some of my projects
21:41:51FromDiscord<mratsim> @Zevv I might be able to update this JIT assembler so that it produces ASM at compile-time as well: https://github.com/numforge/laser/blob/master/examples/ex07_jit_brainfuck_vm.nim#L26-L43

22:01:23Guest16946shashlick - i would like a simple to use configuration system for projects, for example camera saturation values are a modifiable parameter during development stages, however during runtime that parameter should stay constant across all releases of the executable code. currently we are using json files to read the configuration values that way, in
22:01:23Guest16946the future however i would like to do a cross compilation and package the configuration values directly inside the executable
22:01:31Guest16946is there currently a way to do so?
22:02:11Guest16946the issue with json files is we cannot use const on the json file making it still require that configuration file

22:16:50disrupteksure.
22:17:55disrupteki think stdlib has like three different configuration parsers. you can also embed your json as a string, parse it at compile time into a variable, or whatever.
22:18:25Guest16946i am having issues doing:
22:18:53Guest16946`const json: JsonNode = parseJson("data/config.json")`
22:19:39*aenesidemus joined #nim
22:19:45disruptekconst jsonData = staticRead"data/config.json" and then at runtime you can `let js = jsonData.parseJson`
22:20:08Guest16946 Error: invalid type for const: JsonNode
22:20:19FromDiscord<Rika> `const json: JsonNode = static: let data=staticRead"data/config.json" ; parseJson(data)`↵?
22:20:26FromDiscord<Rika> ah
22:20:29FromDiscord<Rika> json node is only runtime
22:20:33FromDiscord<Rika> makes sense
22:20:34FromDiscord<Rika> sorry lol
22:21:06Guest16946i can do it into a const string and than convert it to json node at runtime and than convert into the datastructure i use for configurations
22:21:08disruptekyou can also just `var foo {.compileTime.} = js["somekey"].getInt`
22:21:35disruptekplenty of good options.

22:23:44FromDiscord<Rika> dont use the name json lol
22:24:17Guest16946my bad ya
22:24:24disruptekyour first let is runtime, the var is .compileTime, so it won't work.
22:24:24Guest16946Error: cannot evaluate at compile time: js
22:24:46disruptekyou can use .compileTime on a proc, too, if it's easier.
22:25:03disruptekor define it outside a static block and then work on it inside.
22:25:12Guest16946oh ok ya i have to manually say {.compileTime.} on json
22:25:21Guest16946why can i not just use const on it?
22:25:30disruptekbecause it's on the heap.
22:25:45Guest16946AH ok

23:32:44ldleworkHow can I type alias a seq type?
23:32:54ldleworkI tried type Foos = seq[Foo]
23:32:59ldleworkbut then I'm not sure how to construct it
23:33:51FromDiscord<Rika> `var foos: Foos`?
23:34:18FromDiscord<Rika> itll be initialized then; or you can also do `var foos = newSeq[Foo]()` or something
23:34:20ldleworkhuh that worked
23:34:44FromDiscord<Rika> its just an alias after all
23:35:06ldleworkI didn't know that just defining a var would initialize it
23:37:08FromDiscord<Rika> why not? seqs are no longer nillable
