00:24:09dwdvcollect(for i in 1..3: i) is interesting, almost exactly matches ada's new aggregate expressions (for i in 1..3 => i) syntax. So, when are delta aggregates (mySeq with delta 1..2 => 42) coming to nim? :)
00:25:47*jjido joined #nim
00:26:54leorizewhen someone think that it's a good idea I guess :P
00:27:49leorizeit's purely coincidental that collect() matches ada syntax :)
00:28:59FromDiscord<Rika> what do delta aggregates do
00:29:02dwdvHey, hey, they're even usable with record/objects and arrays. And they even infer their result type.
00:29:34leorizewelcome to macros :)
00:29:41dwdvSimilar to js triple dot operator or whatever it's called. Updating a structure/record/...
00:30:26dwdvleorize: Well, the above isn't true for nim's collect sugar as of now, is it?
00:30:39dwdvOr rather doable.

00:35:17ggibsonAny ideas why this line causes Illegal Storage Access segfault in a dumb one-line fn in a nim dll? "var server = newAsyncHttpServer()"
00:41:14leorizehave you called NimMain() from your dll?
00:41:30ggibsonleorize
00:41:30leorizeif you haven't, the GC will not be activated, and your code won't work
00:41:33ggibsonYes.
00:41:48ggibsonNimMain(); dumbFn();
00:42:05leorizehow did you call your dll?
00:43:08ggibsonIt's a shared library, the header is included in an extern "C" block, and then I just call the function. A simple hello world nim fn works okay, but not the server declaration.
00:43:58ggibsonThis is from c++.
00:44:56leorizeyou should add {.cdecl.} to dumbFn()
00:45:13leorizeon windows the default calling convention is fastcall
00:45:20leorizefor Nim procs
00:45:32leorizeso changing it to {.cdecl.} first should help
00:46:03ggibsonahh, good idea; I'll try that.
00:49:35ggibson@leorize shoot, no luck with cdecl, stdcall, or noconv.
00:50:51ggibsonKnow of any projects that have c/c++ calling code in a nim lib? I haven't found any actual projects that feature this.

01:04:50FromDiscord<Rika> leorize, you know why there isnt any? or did no one think of it
01:05:07leorize@Rika: because people actually implements their functions? :p
01:05:15FromDiscord<Rika> smh
01:05:16ggibsonHah, true. I'll try it on linux and at least get this working there if I can.
01:05:24FromDiscord<Rika> what if i didnt wanna HMMMM

01:10:17ggibsonThanks! Hah yeah I know how that goes.
01:10:32leorizeyou can ignore some complicated stuff in there, since I ported most of the manual work I did to the compiler
01:11:04leorizethe entire codegenDecl part can be turned into dynlib now
01:22:22ggibson@leorize What's the "extern __attribute__..." part for?
01:22:43*ptdel quit (Quit: https://quassel-irc.org - Chat comfortably. Anywhere.)
01:23:53ggibson@leorize You were right - it works like a charm in linux. So it's some sort of fnCall pragma voodoo I probably need to make it work in windows.
01:24:28ggibsonThat or gcc options to do with ffi.
01:26:23leorize[m]ggibson: it's dynlib
01:27:02ggibsonoh, I see. wow.
01:27:17ggibsonThanks for adding dynlib!

01:52:14FromGitter<KingDarBoja> Quick question, is there any recommended text editor for Nim? Currently VSCode Nim extension has some issues
01:52:28shashlickWhat kind of issues
01:52:48shashlickWorks well for me on windows and Linux as well as remote ssh
01:53:49FromGitter<KingDarBoja> Maybe as I am newbie on Nim but for example, declaring a type and importing on another module, while hitting ctrl + s (save) on moduleA, will cause syntax errors on ModuleB and viceversa
01:54:02*disrupteq quit (Ping timeout: 256 seconds)
01:54:34FromGitter<KingDarBoja> And the error always shows on the other module as `This might be caused by a recursive module dependency:`
01:54:36FromDiscord<Rika> huh? probably actual syntax errors
01:54:51FromDiscord<Rika> you're probably actually doing circular imports
01:55:06FromGitter<KingDarBoja> Ummmmm
01:55:08FromDiscord<Rika> try running your code
01:56:16FromDiscord<Rika> can you post code snippets?
01:56:35FromGitter<KingDarBoja> I wanted to create a type on moduleA, let's call it `Foo` and define another type on ModuleB, let's call it Foo.
01:56:42FromGitter<KingDarBoja> Sure
01:57:30FromGitter<KingDarBoja> source.nim ⏎ ⏎ ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=5e75748abef4313854450232]
01:57:52FromGitter<KingDarBoja> location.nim ⏎ ⏎ ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=5e75749f672fdb1545b5bbf5]
01:58:05ggibsonAnd Visual Studio works okay. So I'm left trying to get mingw-gcc c++ calling the nim lib correctly.
01:58:31ggibson(the worst place to be)
01:58:33FromGitter<KingDarBoja> Oh, there is a discord channel
01:59:35shashlickNim doesn't support circular dependencies
02:00:12FromDiscord<Rika> move `from location import SourceLocation, newSourceLocation` below `type Source* ...`
02:00:17FromDiscord<Rika> then it should work
02:00:51FromDiscord<Rika> KingDarBoja ^
02:02:52FromGitter<KingDarBoja> Okie Dokie, didn't know about that
02:07:06FromGitter<KingDarBoja> Ummm still moving the import below `type Source*` triggers some error after hitting save on `location.nim`
02:07:43FromGitter<KingDarBoja> But this time, saving `source.nim` doesn't trigger error on `location.nim`
02:09:04FromGitter<KingDarBoja> Better move all logic from Source `getLocation` proc into Location
02:10:49FromDiscord<KingDarBoja> Hi
02:10:56FromDiscord<KingDarBoja> Managed to found the discord, 😄
02:13:03FromDiscord<KingDarBoja> Anyway, moved the logic and now getting `undeclared field: 'body' for type source.Source` :/
02:13:31FromDiscord<Rika> i mean
02:13:35FromDiscord<Rika> below the whole declaration
02:13:38FromDiscord<KingDarBoja> `var lines: seq[string] = source.body[0..^position].splitLines` maybe this isn't the proper way to get the type prop
02:13:57FromDiscord<KingDarBoja> The whole declaration?
02:14:12FromDiscord<Rika> below `locationOffset: Location`
02:14:24FromDiscord<Rika> the import below the whole type declaration
02:14:37FromDiscord<Rika> so above newsource
02:14:55leorize@KingDarBoja you should avoid circular dependency altogether...
02:14:59FromDiscord<KingDarBoja> That's what I did and once again, when saving `location` , start showing syntax errors
02:15:16FromDiscord<KingDarBoja> 🤔
02:15:30ggibson@leorize FYI I solved my issue - turned out I forgot I had installed ccache months ago, and the compile cache was dirty. yay no nim problems!
02:15:41leorizeggibson: yay
02:15:53leorizejust don't use ccache :p
02:16:14ggibson...yeah seems to be the lesson (it doesn't really help anyway)
02:16:15FromDiscord<Rika> body isnt public
02:16:28FromDiscord<Rika> `body: string` -> `body*: string`
02:16:41FromDiscord<Rika> yes, fields of an object need to publicized
02:16:49FromDiscord<KingDarBoja> Ohhhhhhhhhh
02:17:07FromDiscord<KingDarBoja> That's it!
02:17:26FromDiscord<KingDarBoja> Thanks @Rika and leorize!
02:17:33FromDiscord<Rika> i dont think you also publicized the getLocation procs? not sure
02:18:00FromDiscord<KingDarBoja> No but better avoid the circular thing and declare public the `body` prop
02:18:07FromDiscord<KingDarBoja> Now everything is okay 😄
02:19:02FromDiscord<KingDarBoja> Sorry for that, I am usually coding on Python, didn't expect everything is "private" by default
02:19:50FromDiscord<KingDarBoja> The tutorial part I doesn't seem to mention that
02:20:18FromDiscord<KingDarBoja> I am reading this -> https://github.com/nim-lang/Nim/wiki/Nim-for-Python-Programmers#self__init__
02:20:43leorizeI think the wiki is free for all to edit :)
02:20:55leorizefeel free to add in any information that you deem missing
02:21:33FromDiscord<Rika> `initX` for `object`s, `newX` for `ref object`s
02:21:43leorizeit's not too weird that we got people coming from python and they got confused with now Nim works
02:21:52*ggibson quit (Remote host closed the connection)
02:22:14leorizeNim only looks like python in certain syntactic elements
02:22:40leorizeso if you got any questions, feel free to ask here :)
02:22:46FromDiscord<KingDarBoja> So I do better use `initX` on my current code ugh?
02:22:55FromDiscord<Rika> haha 😛
02:22:58*rnrwashere quit (Remote host closed the connection)
02:22:59FromDiscord<KingDarBoja> Was going to ask the difference between proc / func too lol
02:23:36FromDiscord<Rika> func is proc with `noSideEffects`
02:23:46FromDiscord<KingDarBoja> > `initX` for `object`s, `newX` for `ref object`s
02:23:46FromDiscord<KingDarBoja> @Rika Tell me 😛 😆
02:24:10*chemist69 quit (Ping timeout: 246 seconds)
02:24:17FromDiscord<Rika> proc is `def a(): print("nice")`, func cannot print normally
02:24:24FromDiscord<Rika> because printing edits stdout
02:24:27FromDiscord<Rika> and that is a side effect
02:24:34leorizefunc is basically proc but you don't get to access states outside of your parameters
02:24:39FromDiscord<Rika> that
02:24:52FromDiscord<Rika> outside parameters and result
02:24:59FromDiscord<KingDarBoja> Oh
02:25:28*chemist69 joined #nim
02:25:37FromDiscord<Rika> i recommend using func if needed
02:26:18FromDiscord<KingDarBoja> Okie Dokie 😄 Btw anyone uses vscode-icons (icon theme) ?
02:26:23FromDiscord<Rika> i tried it
02:27:50FromDiscord<KingDarBoja> Well the nim icon is being updated soon, no more black-gold crown lol
02:28:20FromDiscord<Rika> i assume thanks to some KDB
02:28:36FromDiscord<KingDarBoja> 😍
02:29:36FromDiscord<Rika> oh also `decorator` is called `pragma` here
02:29:55leorizenah
02:30:08leorizewe don't have any syntax similar to decorator :P
02:30:16FromDiscord<Rika> no i mean the naming
02:30:27FromDiscord<Rika> i mean more of functionality-similarity-wise
02:30:39leorizebut macros is superior
02:30:45leorizeit's not pragmas, they are macros
02:30:57FromDiscord<Rika> i mean, theyre called pragmas here
02:31:03FromDiscord<KingDarBoja> https://github.com/nim-lang/Nim/wiki/Nim-for-Python-Programmers#decorators What Leorize said...
02:31:45*Kaivo quit (Quit: WeeChat 2.7.1)
02:31:54FromDiscord<Rika> we both know our shit, pragmas are basically macros which take a function
02:32:18FromDiscord<Rika> but the syntax for using them is pragma syntax, not macro syntax
02:32:20FromDiscord<Benumbed> Does anyone know where things stand in terms of stream procs gaining an understanding of endianness? I found the issue in Github but it's languishing 😦
02:32:39FromDiscord<Rika> i understood nothing of what you just said
02:32:59FromDiscord<Benumbed> streams have procs to extract things like uint32s and such
02:33:06FromDiscord<Benumbed> Those have no concept of endianness
02:33:25FromDiscord<Benumbed> meaning if you're streaming something from a network, on a little-endian machine, well, you're going to have a bad time 😄
02:33:33FromDiscord<Benumbed> (at least if you're using those procs)
02:33:48FromDiscord<Rika> well, how exactly do you tell something is little endian or big endian given only the data
02:33:57FromDiscord<Rika> or do you mean as an argument?
02:34:02FromDiscord<Benumbed> The latter
02:34:47FromDiscord<Rika> i got no clue right now since im kinda loopy maybe someone else can help
02:35:02FromDiscord<Benumbed> so someStream.readUint32 would have some way of hinting what ordering was in use so it can be converted to native endianness
02:36:08FromDiscord<Benumbed> The issue in question (RFC) is https://github.com/nim-lang/RFCs/issues/27
02:36:09disbot➥ [RFC] Option for endianness in streams
02:36:59FromDiscord<Benumbed> More interested to see if there's any progress being made on it, or if I should just continue writing my own extractors for streams

02:40:56FromDiscord<KingDarBoja> Quick question, the tutorial shows how to raise an error, is there a quick way to do it inside a if statement or I must create the following:

02:40:59FromDiscord<KingDarBoja> ```
02:41:33FromDiscord<Rika> raise newException(ValueError, msg)
02:41:41FromDiscord<Benumbed> You should be able to just do newException(ExceptionT.... yes that ^ haha

03:03:24FromDiscord<Benumbed> I'm on Disney's cloud team, our products manage the entire company's cloud presence across all 3 major vendors
03:03:35FromDiscord<KingDarBoja> @Rika I have never understood the difference between call and bind so...
03:03:48FromGitter<zetashift> hopefully somebody can sneak in some Nim code into Disney's codebase
03:03:50FromDiscord<Rika> i dont even know what call or bind do
03:04:01FromDiscord<Benumbed> zetashift: Working on it! 😄
03:04:12disruptekcall is what you do to get her over to your place, and bind is what you do to keep her there.
03:04:15FromGitter<zetashift> Ooooo
03:04:18FromDiscord<Rika> you can use code to make node code 🙂
03:04:24FromDiscord<Rika> do it do it
03:04:30FromDiscord<Rika> ok
03:04:34FromDiscord<Rika> i didnt say nim somehow
03:04:37FromDiscord<KingDarBoja> LOL
03:04:41FromDiscord<Rika> you can use nim code to make node code
03:04:49FromDiscord<Rika> im very sleepy zzz
03:05:07FromDiscord<Benumbed> There's talk of converting our services to Go, which, having actually learned Go... I'm not entirely pleased about either haha
03:05:10FromDiscord<KingDarBoja> Now think about JS community with those frameworks, libraries, etc
03:05:23FromDiscord<Benumbed> Gp
03:05:28FromDiscord<Rika> Gp?
03:05:34FromDiscord<Benumbed> err Go's package ecosystem is a nightmare
03:05:36FromGitter<zetashift> Yeah I think Go is Nim's biggest contender in the space Nim wants to occupy
03:05:38FromDiscord<Rika> yeah
03:05:45FromDiscord<KingDarBoja> What about Rust?
03:05:49FromDiscord<Rika> heard of Go's package system and hhhhh
03:05:55*actuallybatman left #nim (#nim)
03:05:58FromDiscord<Rika> Rust is an okay package system from what i tried
03:06:03FromDiscord<Benumbed> Rust is too high of a learning curve for what we do
03:06:06FromDiscord<Benumbed> and also overkill
03:06:07FromGitter<zetashift> If they can live with a GC, I think you'd want to avoid rust
03:06:10FromDiscord<KingDarBoja> Rust has Cargo, Go?
03:06:16FromDiscord<Rika> go has uh
03:06:21FromDiscord<Rika> forgot the name
03:06:33FromDiscord<Benumbed> dammit I know this... Go modules or something
03:06:36FromGitter<zetashift> iirc they were working on it
03:06:39FromDiscord<KingDarBoja> Oh yeah
03:06:44FromDiscord<KingDarBoja> Go modules
03:06:45FromDiscord<Rika> TBH Cargo sounds more like a Go package manager than a Rust one, because, uh, carGO
03:07:00FromDiscord<Benumbed> I was using them right before I moved my efforts to Nim
03:07:20FromDiscord<KingDarBoja> Go has several package managers as far as I know
03:07:23FromDiscord<Benumbed> The Go modules are out of beta in 1.13 (latest) I think
03:07:30FromDiscord<KingDarBoja> Then they went to only one trying to standarize it
03:07:41disruptek!repo nimph
03:07:43disbothttps://github.com/disruptek/nimph -- 9nimph: 11Nim package hierarchy manager from the future 🧚 15 54⭐ 3🍴 7& 1 more...
03:07:56FromDiscord<Rika> most people say that Go is too simplistic making it boilerplate heavy
03:07:56FromDiscord<KingDarBoja> Wait what?
03:08:09FromDiscord<Rika> yeah disruptek made another package manager
03:08:13FromDiscord<KingDarBoja> Where is nimble lol
03:08:15FromDiscord<Rika> never used it
03:08:16FromDiscord<Benumbed> lol
03:08:31FromDiscord<Benumbed> nimble drives me nuts when it comes to how it handles tests
03:08:35FromDiscord<Rika> nimble is the one packaged with nim
03:08:37FromDiscord<Rika> why so?
03:08:48FromDiscord<Benumbed> I have an item in my list of TODOs to figure out how to make it better
03:08:52FromGitter<zetashift> Rika, I think you have to choose your projects for Go, for web services seems great
03:08:55FromDiscord<KingDarBoja> Neither I but hopefully it doesn't become too many of them
03:09:00FromDiscord<Benumbed> Nimble doesn't traverse directory structures to run tests
03:09:02*rnrwashere joined #nim
03:09:07*rnrwashere quit (Remote host closed the connection)
03:09:08FromDiscord<Benumbed> it just looks in the root of the test directory
03:09:17FromDiscord<Benumbed> also, it likes to write the executable next to the .nim
03:09:20FromDiscord<KingDarBoja> As JS has npm, yarn, pnpm, etc
03:09:22FromDiscord<Rika> maybe testament fixes what unittest lacks
03:09:31FromDiscord<Benumbed> which makes .gitignores a nightmare trying to not check in executables
03:09:54FromGitter<zetashift> @Benumbed try to open an issue, iirc the people working on nimble are open for ideas
03:09:55FromDiscord<Rika> i think theres a parameter for that
03:10:03FromDiscord<Rika> --out was it? not sure
03:10:09FromDiscord<Rika> outDir? dunno
03:10:20FromGitter<zetashift> yea
03:10:25FromDiscord<Benumbed> zetashift: I was going to try and actually figure a better way out myself and then submit an MR
03:10:28FromGitter<zetashift> `nim c -o:path`
03:10:38FromDiscord<KingDarBoja> 😮
03:10:45FromGitter<zetashift> man I read that as submit an MRI
03:10:55FromDiscord<Benumbed> Heavy stuff... O_o 😄
03:11:08FromDiscord<Rika> only reason i understood MR is because MR sounds like (mer)ge
03:11:25FromDiscord<Benumbed> I use 'MR' because not everyone uses Github 🙂
03:11:59FromGitter<zetashift> fair
03:12:15FromDiscord<Benumbed> I do actually use -o all the time (I compile to a build/ directory so I can just gitignore it), but it only works for single files
03:12:31FromDiscord<Benumbed> What would be helpful is a 'write all binaries to <this> dir' argument
03:12:46FromGitter<zetashift> might be able to do it with nimscript
03:13:18FromDiscord<Rika> anyone here who can help me out with my endeavor to translate this lib though (i mean, less of those who can read python and more of those who are knowledgeable on osu core functionality, as the library i'm translating has errors in the code)
03:13:19FromGitter<zetashift> I'm not sure though, most people here are EU so they can't weigh in cause they're sleeping :(
03:13:25FromDiscord<Benumbed> I'll probably look into a 'fix' once I get to the point with the AMQP client where I have a bunch of tests that I want to build
03:13:55FromDiscord<Benumbed> Not I unfortunately, the closest I get to osu is watching vids on YouTube
03:14:30FromGitter<zetashift> osu as in the rhythm game?
03:14:34FromDiscord<Rika> yep
03:14:45FromGitter<zetashift> yea also youtube vids for me
03:14:55FromDiscord<Rika> xdddd
03:15:21FromDiscord<Rika> okay ill just ask this then, what's the best approach for me to parse a file that looks like a windows INI file but isnt exactly one?
03:16:29FromDiscord<Benumbed> That is the sort of stuff that ends up irking me lol
03:16:29FromGitter<zetashift> Is there an existing implementation in another language maybe?
03:16:52FromDiscord<Benumbed> Can you pre-process the file down to legit INI syntax, then use an INI parser?
03:17:08FromDiscord<Benumbed> Can you pre-process the file down to actual INI syntax, then use an INI parser?
03:17:22FromDiscord<Benumbed> Shit, forgot I'm not supposed to edit, sorry IRC folks
03:17:31FromDiscord<KingDarBoja> OOOHHH it is that tap game!
03:17:38FromDiscord<Benumbed> Discord and Slack habits are engrained in me
03:17:41FromDiscord<Rika> THAT TAP GAME
03:18:25FromDiscord<Rika> i guess ill just uh look elsewhere
03:19:15FromDiscord<Benumbed> Hey, I made a suggestion! Sorta... 😄
03:20:10FromDiscord<KingDarBoja> I am very tired, gotta go 😄 see ya tomorrow!
03:20:32FromDiscord<Benumbed> nn

03:24:07FromDiscord<Benumbed> Well gee, I feel like a double dumbass, thanks
03:24:09FromDiscord<Benumbed> 😄
03:24:36FromDiscord<Rika> what exactly is a closure iterator
03:24:52FromDiscord<Rika> and how do i distinguish a regular one from a closure one
03:24:56disrupteklike a python generator, an iterator that you can iterate on demand.
03:25:15FromDiscord<Benumbed> Wouldn't that just be a closure that `yeild`s?
03:25:22FromDiscord<Benumbed> yield dammit fingers
03:25:53FromDiscord<Rika> well is it possible to convert a regular iterator to a closure iterator
03:26:18FromDiscord<Rika> w/o editing the source of the regular iterator
03:28:35FromDiscord<Rika> nvm
03:28:38FromDiscord<Rika> lmao

16:02:06leorize^ that's the operator doing the copy
16:02:54leorizeoh I misread
16:03:08leorizethe rhs there will be a constant buffer in your program, on the stack
16:03:18axionthat's pretty nice. thanks

16:05:48axionOnly thing I wish for is a syntax for combined slices. like a[1..3,10..12] = [1..6]. maybe i'll have to write a macro for this some day

16:14:16axionI'm not very familiar with Nim yet to know if that function call overhead will get folded away

16:35:12leorizeaxion: yea I can see what you meant, so here's a tip when you implement that: use toOpenArray for copy-less slicing :)

17:37:47FromGitter<kristianmandrup> @alehander92 I fixed the react code so it can now compile and be used. Still some way to go to make it "fully functional" in a real app though

17:45:59FromDiscord<KingDarBoja> Wow, Latin American power!
17:46:28FromDiscord<KingDarBoja> I got another Python related question
17:46:48FromDiscord<KingDarBoja> Anyone has used Enums on Python like assigning a string value instead of a integer one
17:47:10FromDiscord<KingDarBoja> Can I do the same in Nim? so far looks like no 🤔
17:48:04disruptektype MyEnum = enum Value1 = "firstValue", Value2 = "2ndValue"
17:48:22FromDiscord<KingDarBoja> Oh!
17:48:59FromDiscord<KingDarBoja> From the tutorial part I:
17:48:59FromDiscord<KingDarBoja> > _A variable of an enumeration type can only be assigned one of the enumeration's specified values. These values are a set of ordered symbols. Each symbol is mapped to an integer value internally._
17:49:28FromDiscord<KingDarBoja> I got confused by the mapping part
17:49:41disruptekyes. but what you're doing here is syntactically providing a string constant for the enum.
17:49:52disrupteksuch that $Value1 == "firstValue"
17:50:01disruptekit is otherwise an integer.
17:50:08disruptek^ordinal, rather.
17:50:32FromDiscord<KingDarBoja> Thanks once again!

18:13:55FromDiscord<KingDarBoja> Another question but related to Nim, how to do a test suite? Like python has pytest (or unittest)
18:15:21FromGitter<zetashift> Nim has unittest
18:15:32FromGitter<zetashift> and you can run your tests with nimble test
18:15:39FromGitter<zetashift> If that is what you mean
18:15:59FromDiscord<KingDarBoja> https://nim-lang.org/docs/unittest.html this one u mean?
18:16:39dadadaKingDarBoja: yes, I'm using it right now, it's simple
18:17:32FromDiscord<Recruit_main707> how can i compile my program so that its 32bit instead of 64?
18:18:02FromDiscord<KingDarBoja> Gonna try it, if any question, I will return, thanks 😄
18:22:31FromGitter<kaushalmodi> Recruit_main707: `nim c --cpu:i386 --passC:-m32 --passL:-m32 foo.nim`
18:22:57FromGitter<kaushalmodi> https://scripter.co/notes/nim/#compiling-in-32-bit-mode
18:23:03PMunchDoesn't --cpu:i386 set the m flags?
18:23:10leorizenope
18:23:46leorizethough we can certainly make it do so
18:24:42PMunchIs there a reason why it doesn't?
18:26:10FromDiscord<KingDarBoja> Ummm having problems to import some module
18:26:53FromDiscord<KingDarBoja> If my dir structure is like:
18:26:53FromDiscord<KingDarBoja> - src
18:26:53FromDiscord<KingDarBoja> -- dirA
18:26:53FromDiscord<KingDarBoja> --- moduleA.nim

18:26:54FromDiscord<KingDarBoja> - test
18:26:54FromDiscord<KingDarBoja> -- some_file.nim
18:27:08FromDiscord<KingDarBoja> I want to import moduleA stuff on some_file inside my test dir
18:36:47leorizeimport dirA / moduleA
18:37:26FromDiscord<KingDarBoja> Without the src part?
18:39:52FromDiscord<KingDarBoja> https://github.com/nim-lang/nimble#tests I added this but without success
18:40:38FromDiscord<KingDarBoja> Nevermind, looks like it is VSCode once again showing errors on save after switching files
18:48:55FromDiscord<KingDarBoja> `Error: invalid module name: .nim` wut? After running nimble test
18:48:59*rnrwashere joined #nim
18:52:21FromDiscord<KingDarBoja> Had to provide whole path to the nim file including the test file name
18:53:06FromDiscord<KingDarBoja> It is possible to run all tests inside the `tests` folder? Or I have to specify each one on my test task?
18:54:04FromDiscord<Recruit_main707> compilation failed, it could be that i call kernel.dll?
18:55:43axionHow would I construct a large array of all zeros in a let binding without specifying all the values?
18:55:44leorize@KingDarBoja: import without the .nim part :P
18:55:57leorizeaxion: use default(T)
18:56:08axionhmm
18:56:59axionI'm not familiar with how to use that
18:57:25leorize!eval let array = default(array[100, int]); echo array
18:57:28NimBot[0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
18:58:06axionI see. and if I wanted non-zero I'd have to use algorithm.fill?
18:58:26FromDiscord<KingDarBoja> Arhhh have no idea how to compare a Enum value with a string
18:58:58FromDiscord<KingDarBoja> Like `x = south` (from the tutorial example), want to do `check(x == "south")`
18:59:07FromDiscord<KingDarBoja> But doesn't work (error on the console)
18:59:19leorizeaxion: yea
18:59:26leorizethough it'll look like this instead:
18:59:34disruptek$someEnum == "some string"
18:59:34FromDiscord<KingDarBoja> `Error: type mismatch: got <Direction, string> but expected one of:proc ==[Enum: enum](x, y: Enum): bool`
19:00:06leorizeimport algorithm, sugar; let array = default(array[100, int]).dup(fill(10)); echo array
19:00:14FromDiscord<KingDarBoja> 🤦‍♂️ Ah...
19:00:34leorizeaxion: that snippet requires devel though
19:00:45axionah i have to look up dup
19:00:55FromDiscord<KingDarBoja> What about:

22:08:24FromDiscord<Kenran> I'm trying to do something with the `sdl2` library. While copying the example code, I got "type mismatch: got <Bool32> but expected 'bool'" in `while pollEvent(evt):`. `pollEvent` does indeed return `Bool32`. How can I get out of that?
22:09:13*vesper11 quit (Ping timeout: 250 seconds)
22:10:35FromDiscord<Kenran> Oh, nevermind, I could get rid of the error by changing my `from sdl2 import nil` to `import sdl2` on a hunch. I still don't understand why that fixes it, though. Any hint?
22:11:48*vesper11 joined #nim
22:13:15YardanicoProbably because sdl2 module contains a converter which converts Bool32 to bool automatically
