01:07:27FromDiscord<Varriount> Hrm.↵From a design level, anyone have idea why using `0`, `1`, and `2` for standard input, output, and error streams, and `-1` for an invalid stream, would be better than using `1`, `2`, `3`, and `0`, respectively?

06:07:23FromDiscord<Varriount> @leorize Huh, that hasn't occurred to me. Of course, that also begs the question, "why -1 and errno"
06:07:55FromDiscord<Varriount> Or on Windows, GetLastError
06:17:14FromDiscord<Bung> is there any cross-platform inotify like lib ?
06:29:46FromDiscord<Bung> the `segfaults` module means when access nil I can get stacktrace info like other exception ?
06:32:47*perepujal joined #nim
06:33:22*perepujal quit (Remote host closed the connection)
06:34:26FromDiscord<haxscramper> No, you get stacktrace on nil access anyway, but `std/segfaults` turns it into `NilAccesDefect` that can be caught
06:34:34FromDiscord<haxscramper> So you get actual defect raised
06:34:44FromDiscord<haxscramper> Stacktrace is always available
06:37:02FromDiscord<haxscramper> sent a code paste, see https://play.nim-lang.org/#ix=3pxw
06:37:35FromDiscord<haxscramper> Though `NilAccess` is a defect and if I remember correctly it cannot be caught with `--panics:on` (disabled by default)
06:47:09FromDiscord<Bung> oh, I may remenber wrong, it's in dll , when access nil only one line error message
06:47:26leorize[m]@Varriount I guess errno allows for a kind of deterred error handling, though it's worth noting that some operations can return a not -1 value and have errno set
06:50:45leorize[m]or it could simply because creating a local to store potential error codes on every syscall was too tiring in C :p
06:51:10*gmaggior joined #nim
06:59:08leorize[m]for Windows the MS wanted to use every single bit in a DWORD to describe a given error, which I think is one of the reasons for it to be placed behind a procedure
07:00:10leorize[m]the same rationale might have driven errno as well, but with modern standards enforcing positive errno values I doubt it was the true reason
07:04:32FromDiscord<Rainbow Asteroids> why are panics disabled by default? Y'all don't want to break nonsensical code? lol
07:05:43leorize[m]yep, it's meant to be enables by default but people were catching them left and right, so we gotta compromise
07:05:49leorize[m]enabled*
07:07:04FromDiscord<Rainbow Asteroids> maybe in new nimble projects, the switch should be enabled in the config by default or smth
07:07:56leorize[m]too risky, the issue was that some libraries needed this to function
07:08:17leorize[m]there will be plans to have it on by default alongside gc:orc
07:08:31FromDiscord<Rika> What did panics do again

09:07:13FromDiscord<haxscramper> Actually https://nim-lang.org/docs/io.html#setFilePos%2CFile%2Cint64%2CFileSeekPos might be berrer

09:11:49FromDiscord<Rika> that goes to byte 44 yes
09:12:50FromDiscord<System64 ~ Flandre Scarlet> But the values I want to read are int16 (16-bits signed int), it uses 2 bytes, so how can I read it?
09:14:02FromDiscord<Rika> multiply by the byte size?

09:16:29FromDiscord<Rika> which
09:17:01FromDiscord<mlokis> sent a code paste, see https://play.nim-lang.org/#ix=3py9
09:17:22FromDiscord<mlokis> this is a deep shit
09:17:38FromDiscord<haxscramper> `type mismatch: got 'array[0..1, tuple[speed: int, damage: int]]' for '[(speed: 1000, damage: 10), (speed: 10, damage: 0)]' but expected 'array[0..1, Bullet]'`
09:17:59FromDiscord<haxscramper> Are you sure this is the same code as generated by macro
09:18:07FromDiscord<mlokis> yes
09:18:22FromDiscord<haxscramper> Because your one is not valid and error is perfectly clear - you can't assign array of tuples to array of objects
09:18:47FromDiscord<mlokis> i ll try something maybe am just stupid

09:19:11FromDiscord<Davide> (edit) "https://play.nim-lang.org/#ix=3pya" => "https://play.nim-lang.org/#ix=3pyb"
09:19:19FromDiscord<haxscramper> `expandMacros` is not sufficient when dealing with macro code that generates errors
09:19:28FromDiscord<haxscramper> Hopefully `nkError`will fix that
09:19:31FromDiscord<Davide> (edit)
09:20:05FromDiscord<haxscramper> In reply to @System64 "Ah there is readInt16": It will read int16 from current position, so seek must calculate it correctly regardless
09:20:11FromDiscord<mlokis> sent a code paste, see https://play.nim-lang.org/#ix=3pyc
09:20:23FromDiscord<Rika> can you give the macro
09:20:41FromDiscord<haxscramper> yeah, full macro is preferrable
09:20:46FromDiscord<mlokis> macro is big but as you wish
09:20:52FromDiscord<System64 ~ Flandre Scarlet> In reply to @haxscramper "It will read int16": So I need to do +2 at each iteration?

09:26:01FromDiscord<haxscramper> In reply to @mlokis "": Also `std/macros.error` has optional (FFS who made it optional that gives you position of the node on error)
09:27:01FromDiscord<mlokis> yea i was kind of lazy to do that as i em only person who will use ithat macro

09:39:09FromDiscord<System64 ~ Flandre Scarlet> ah but my file is a stream
09:39:41FromDiscord<mlokis> os should have information about file size
09:40:00FromDiscord<haxscramper> use `File/open/setFilePos/getfileSize` then
09:40:07FromDiscord<haxscramper> from `std/io`
09:40:58FromDiscord<Rika> i just sent that
09:41:11FromDiscord<Rika> theyre using a filestream
09:42:40FromDiscord<haxscramper> I mean streams don't have an API for that, so they should use `File`

15:27:43giga84?
15:28:33Prestigejava isn't javascript
15:28:34FromDiscord<exelotl> no, javascript is a completely different language to java, there are no terms and conditions attached to using javascript
15:28:36FromDiscord<System64 ~ Flandre Scarlet> In reply to @giga84 "won't it violate java": JavaScript != Java
15:30:01giga84hmm wikipedia says "Trademark
15:30:02giga84"JavaScript" is a trademark of Oracle Corporation in the United States"
15:30:33giga84how can u write a webapp without their permission
15:30:48giga84in nimlang
15:30:49PrestigeCan you link that? Doesn't sound right
15:31:04giga84https://en.wikipedia.org/wiki/JavaScript#Trademark
15:31:12FromDiscord<System64 ~ Flandre Scarlet> Why??? https://media.discordapp.net/attachments/371759389889003532/852932986202357800/unknown.png
15:33:47FromDiscord<System64 ~ Flandre Scarlet> that's weird
15:33:54PrestigeThat's very interesting giga84
15:33:55FromDiscord<Bung> array size should be const
15:33:57PrestigeI had no idea
15:35:02FromDiscord<System64 ~ Flandre Scarlet> that's even worse now https://media.discordapp.net/attachments/371759389889003532/852933952847347732/unknown.png
15:35:39Prestigebut anyway giga84 you can use JS freely afaik, but can't claim ownership of javascript
15:36:23giga84so basically you can write an webapp with nim lang and sell it
15:36:40giga84without owing royalties to oracle
15:36:48*ZoomZoomZoom quit (Ping timeout: 240 seconds)
15:37:10FromDiscord<exelotl> yes, same as how you can write an app in JS without owing royalties to oracle
15:37:26FromDiscord<System64 ~ Flandre Scarlet> I don't think you need to ow royalties for using a programming language
15:38:34FromDiscord<Bung> just dont use their trademark, they dont limit you use the language
15:38:49giga84yes but your programming language converts nimlang code java script code
15:39:10FromGitter<tandy1000:matrix.org> im having trouble getting nimble to build documentation for my project
15:39:13giga84hence by using you don't owe royalties

15:44:11FromDiscord<System64 ~ Flandre Scarlet> I try to make an array to store values
15:45:40FromDiscord<Bung> your `size` is asignment on runtime
15:46:11FromDiscord<Bung> you can't just `.const` it's not a type to convert
15:46:24FromDiscord<System64 ~ Flandre Scarlet> Ah I see↵And if I do a Seq?
15:46:50FromDiscord<Bung> indeed, if your size can't determine at compile type
15:46:56FromDiscord<Bung> time
15:47:03FromDiscord<System64 ~ Flandre Scarlet> I can't at compile time

17:13:38FromDiscord<gerwy> because i mostly want to do it because of performance, because i have enum of things and based on the value of that i want to do something every frame↵but using if's or case can be pretty slow so i thought about using array of functions
17:14:05FromDiscord<gerwy> Also i don't see you Lefl in godot discord anymore, what happend?
17:14:26FromDiscord<haxscramper> In reply to @Life Sucks "because i mostly want": Using `case` is faster than callbacks
17:14:31FromDiscord<haxscramper> Why do you think it is slow?
17:14:33FromDiscord<gerwy> why?
17:14:38FromDiscord<gerwy> In reply to @haxscramper "Why do you think": branches

17:15:10FromDiscord<demotomohiro> @Life Sucks You dont need to put function definition in array. You can create an array of function with function names
17:15:11FromDiscord<haxscramper> In reply to @Life Sucks "branches": vs what? branches vs function call, pointer indirection etc.
17:16:42FromDiscord<haxscramper> computed goto with `case` results in the best performance for interpreter loops, but it all depends on your particular use case.

17:23:16FromDiscord<haxscramper> In reply to @Life Sucks "Idk i just thought": I don't think it would be faster in any language, especially considering you are guaranteed to have at least one layer of indirection when calling procedure (also environment access if you have a closure)
17:24:41FromDiscord<haxscramper> What are you writing btw?

17:25:30FromDiscord<Lefl> Oh nvm I just read his last message
17:26:04FromDiscord<gerwy> In reply to @haxscramper "What are you writing": Game :3
17:26:40Prestigeoh what are you using?
17:26:58FromDiscord<gerwy> And the code would be part of one "Minion" Ai so if there was a lot of them then the performence can drop a lot
17:28:02FromDiscord<haxscramper> using `array[Enum, proc()]` allows to switch behavior at runtime for example (and lots of things that are not possible with hardcoded `case`)
17:28:15FromDiscord<haxscramper> So you really need to bench things for your use case
17:28:34FromDiscord<gerwy> In reply to @Prestige "oh what are you": raylib
17:29:06FromDiscord<Lefl> I think I'll go back to the 2 program solution instead of trying this abominations

17:30:48FromDiscord<gerwy> In reply to @Lefl "I think I'll go": Isn't there python interpreter in nim packages, you could try that right?
17:31:26FromDiscord<Lefl> There's nimpy, but I can't figure out how or if it's possible to pass an nim object to a python function
17:33:52FromDiscord<gerwy> hmm↵do you write code in nim or python?↵I know that there is a way to write python modules in nim so if you write it in python you could use that
17:34:20FromDiscord<Lefl> I'm trying to use a bluetooth LE library in nim
17:34:46FromDiscord<Lefl> Yeah maybe I could somehow use a C library, but I have no idea how that works
17:35:41FromDiscord<gerwy> i heard that c2nim turns C libraries to be usable for nim↵because raylib bindings used that
17:36:01FromDiscord<Lefl> hmm
17:37:53FromDiscord<gerwy> sent a code paste, see https://play.nim-lang.org/#ix=3pAY
17:38:04FromDiscord<gerwy> the game would be something like Stick War, the good ol' flash game
17:38:11FromDiscord<Lefl> Hmm I'll also have to find a C BLE library, everything is C++
17:39:22FromDiscord<haxscramper> you can interop with C++ as well
17:39:34FromDiscord<haxscramper> and c2nim "supports" "part" of the C++
17:39:59FromDiscord<demotomohiro> Nim can wrap C++ library, but you would need some C++ lang features
17:40:31FromDiscord<haxscramper> such as? Depending on which feature you need
17:41:15FromDiscord<demotomohiro> You would need to know some C++ lang feature
17:41:16FromDiscord<haxscramper> I.e. is there an explicit lack of features that prevent you from using C++ library (like it uses variadic generics for example)
17:41:34FromDiscord<haxscramper> In reply to @demotomohiro "*You would need ": ah, well
17:42:59FromDiscord<demotomohiro> Even if you can wrap c or c++ library for Nim, you would need to read a library documents or example code that are written for C/C++ programmer
17:44:33*sveit joined #nim
17:45:05*sveit quit (Remote host closed the connection)
17:45:11FromDiscord<demotomohiro> So, using c or c++ library with Nim without knowing C/C++ can be hard unless someone write a good document or example code for Nim programmer
17:46:04FromDiscord<gerwy> yeah, its better to know, at least C or C++↵they are similar so you probably need only one to know it well to use docs
17:46:16FromDiscord<haxscramper> huh
17:46:30FromDiscord<haxscramper> they are not similar,
17:46:42FromDiscord<haxscramper> Unless you write C in C++ at least
17:46:43FromDiscord<gerwy> but if you know C++ you can understand C
17:47:22FromDiscord<haxscramper> True, but it does not work other way around. And some C idioms are different from C++ still
17:47:54FromDiscord<gerwy> ah yes
17:48:02FromDiscord<gerwy> i mean like C++ -> C relation
17:48:19FromDiscord<gerwy> because i know C++, at least a little and i think i can understand C code if i see it

17:52:22FromDiscord<System64 ~ Flandre Scarlet> Not as string
17:53:23FromDiscord<haxscramper> And what 'seq of bytes' is then? nim `string` uses `char` so it can be viewed as sequence of bytes

18:55:40leorize[m]it depends on what you need but seems to me that this code should be replaced with sys/exec, which doesn't exist atm

19:17:35FromDiscord<Bung> yeah , works with ssl flag , Thanks!
19:18:45FromDiscord<haxscramper> I tested package parser on all packages that were available at march 2021, so it should be relatively robust, but I haven't handled all edge cases
19:18:53FromDiscord<haxscramper> So it might break at some places
19:19:24FromDiscord<haxscramper> Also use `parsePackageInfo` instead of `nims` version as there are some packages that use old format
19:20:16FromDiscord<Bung> `let x = staticRead("../../nimble.nimble")` in `nimblepkg/common.nim` it looks weird ? a relative path to static read
19:20:52FromDiscord<haxscramper> if you have `srcDir = "src"` it would break when package is installed
19:21:00FromDiscord<haxscramper> But this `srcDir` is broken AF
19:22:15FromDiscord<haxscramper> so you need `staticRead` + check whether it is `../nimble.nimble` or `../../nimble.nimble`
19:24:36FromDiscord<Bung> think it breaks because use it as package
19:25:10FromDiscord<Bung> it should move to bin main file I think
19:25:35FromDiscord<haxscramper> if you have binary package it would still download sources and compile them
19:25:55FromDiscord<haxscramper> but I"m not sure how files are moved in this case (e.g. whether `srcDir` is respected or not)
19:27:47FromDiscord<Bung> all files will move out from src, src doesn't exists after installing
19:29:29FromDiscord<Bung> the simple solution will define a prepublish task simple dump version to a single file
19:30:27FromDiscord<haxscramper> In reply to @Bung "`let x = staticRead("../../nimble.nimble")`": I think this approach is good enough, you just have to be aware of the `srcDIr` file movements
19:33:16FromDiscord<Bung> well, I still need change the common.nim to make it work
19:35:18FromDiscord<Bung> am wondering how nim version update to system.nim
19:36:28FromDiscord<Bung> oh it use defined flag so other program defines
19:37:34FromDiscord<haxscramper> just has integer value that is manually incremented https://github.com/nim-lang/Nim/blame/44e653a9314e1b8503f0fa4a8a34c3380b26fff3/lib/system.nim#L2114
19:37:56FromDiscord<haxscramper> I mean we don't have releases that often so it become an issue
19:38:53FromDiscord<Bung> make sense, well.
19:44:06FromDiscord<System64 ~ Flandre Scarlet> Do you know what's the problem with my code please?
19:58:09FromDiscord<Bung> can you make a repo that I can directly run , then I can take a look
19:59:36FromDiscord<System64 ~ Flandre Scarlet> alright so I checked and NewSample contains the right sequence of data
20:01:39FromDiscord<Bung> okay

20:37:51FromDiscord<Bung> your newFileStrm size is determined
20:38:14FromDiscord<Bung> you can't just setPosition to any position
20:39:14FromDiscord<zetashift> In reply to @leorize "the pipes layer is": So how would I connect a pipe given a certain address(like `"\\\\.\\pipe\\nvim-7072-0"`)?
20:39:43FromDiscord<System64 ~ Flandre Scarlet> var newFileStrm = newFileStream("sample2.wav", fmWrite)↵I init my stream there
20:40:06leorize[m]@zetashift you can't because I haven't implemented named pipes yet
20:40:25FromDiscord<zetashift> ah I didn't see the issue of named pipes so I thought maybe I was looking wrong
20:41:27leorize[m]named pipes are sorta complicated, which is why I haven't give them a proper API
20:41:31leorize[m]but I'll see what I can do for you
20:43:33FromDiscord<zetashift> It's okay! I'll try and get a tcp connection with neovim working in the meantime
20:43:40leorize[m]ok it's not that complicated, I just have to build the file system layer
20:43:49leorize[m]alternatively you can just use stdlib's openFile
20:46:55FromDiscord<System64 ~ Flandre Scarlet> Why OutOfRange? It's a Seq and I add elements in https://media.discordapp.net/attachments/371759389889003532/853012441121947668/unknown.png
20:47:25FromDiscord<System64 ~ Flandre Scarlet> Why OutOfRange? It's a Seq and I add elements to it https://media.discordapp.net/attachments/371759389889003532/853012563087065148/unknown.png
20:48:13FromDiscord<ElegantBeef> It's len is probably less than 42
20:48:31FromDiscord<System64 ~ Flandre Scarlet> I crash at the line 58
20:48:51FromDiscord<ElegantBeef> index is outside of 0-255
20:48:59FromDiscord<ElegantBeef> so cannot convert to a char
20:49:38FromDiscord<System64 ~ Flandre Scarlet> it's a signed 8-bits array
20:49:54FromDiscord<ElegantBeef> so it's less than 0 eh?
20:49:59FromDiscord<System64 ~ Flandre Scarlet> yeah
20:50:27FromDiscord<ElegantBeef> !eval let a = (-1i8).char
20:50:29NimBotCompile failed: /usercode/in.nim(1, 15) Error: -1 can't be converted to char
20:50:57FromDiscord<ElegantBeef> It's ambiguous what that should be, convert to int16 add 127 then convert to char
20:51:02FromDiscord<System64 ~ Flandre Scarlet> I need to put the data of this Seq in my file↵'cause the Wav is signed
20:51:25FromDiscord<ElegantBeef> Atleast that's what i'd do, no clue what's "proper"
20:52:09FromDiscord<System64 ~ Flandre Scarlet> I want to convert a signed 16-bits wav to signed 8-bits wav
20:52:20FromDiscord<ElegantBeef> So then why do you need char?
20:53:03FromDiscord<System64 ~ Flandre Scarlet> To put it in my data stream
20:53:24FromDiscord<ElegantBeef> That makes no sense
20:53:43FromDiscord<System64 ~ Flandre Scarlet> I use that : newFileStrm.writeLine(str)
20:53:58FromDiscord<ElegantBeef> https://nim-lang.org/docs/streams.html#write%2CStream%2CT
20:54:00FromDiscord<Bung> all things you write in the end are chars
20:54:30FromDiscord<Bung> so could just turns your input data to chars first ?
20:54:52FromDiscord<zetashift> In reply to @leorize "alternatively you can just": ah thanks, I think I need to gain some more knowledge about these low level OS specifics, I thought this weekend adventure would be a bit easier 😛
20:54:55FromDiscord<ElegantBeef> Or just write the value to the file
20:55:18FromDiscord<ElegantBeef> But you can if you must `cast[char](index)` though it's pointless when you can just write the data
20:56:34FromDiscord<Bung> the only concern is do you know how you ints turns to chars properly
21:00:36FromDiscord<System64 ~ Flandre Scarlet> The new file is messed up if I do newFileStrm.write(newSample)
21:01:49FromDiscord<ElegantBeef> Well what is supposed to be written when you go to write `-1`?
21:02:07FromDiscord<System64 ~ Flandre Scarlet> hex value
21:02:37FromDiscord<System64 ~ Flandre Scarlet> I mean, like what you see in HxD
21:02:47FromDiscord<ElegantBeef> So you mean the binary value of `-1` so what it did
21:03:27FromDiscord<System64 ~ Flandre Scarlet> I want to write the binary value of -1
21:03:34FromDiscord<ElegantBeef> Which is what `stream.write` should write
21:04:35FromDiscord<System64 ~ Flandre Scarlet> ah maybe it writes the memory adress of the seq?
21:04:45FromDiscord<ElegantBeef> yes
21:05:21FromDiscord<ElegantBeef> If you're writting a seq do `writeData(seq[0].addr, seq.len)`
21:05:23FromDiscord<ElegantBeef> (edit) "writting" => "writing"
21:06:08FromDiscord<System64 ~ Flandre Scarlet> aaaah let me try that

21:21:44FromDiscord<System64 ~ Flandre Scarlet> alright I see something weird

21:26:18FromDiscord<Lefl> It loogs ugly
21:26:23FromDiscord<ElegantBeef> Well let's fix ut
21:26:25FromDiscord<ElegantBeef> (edit) "ut" => "it"
21:30:01FromDiscord<ElegantBeef> This is marginally better https://play.nim-lang.org/#ix=3pCm
21:30:05FromDiscord<ElegantBeef> But we can do it even better
21:31:47FromDiscord<Lefl> Hmm
21:34:18FromDiscord<ElegantBeef> Now we're cooking with gasoline https://play.nim-lang.org/#ix=3pCr
21:36:13FromDiscord<Lefl> Oh boy that's sexy
21:36:14FromDiscord<Lefl> thanks
21:36:28FromDiscord<ElegantBeef> No problem, embrace the block call style
21:36:39FromDiscord<Lefl> what does the {.inject.} pragma do?
21:36:48FromDiscord<ElegantBeef> in templates it doesnt add gensym to the name
21:36:55FromDiscord<ElegantBeef> so you can use `it` inside the blocks to access that value
21:37:23FromDiscord<Lefl> What's gensym?
21:37:41FromDiscord<ElegantBeef> ensured unique name so without it that `it` is actually `itgensym0`
21:37:51FromDiscord<ElegantBeef> And i dont think can be accessed anyway
21:38:16FromDiscord<Lefl> Ok
21:38:23FromDiscord<ElegantBeef> Templates are hygenic which means unless otherwise specified like with the inject they dont emit symbols that are accessible
21:38:45FromDiscord<ElegantBeef> I could've also put `{.dirty.}` on the template but that'd have emitted `pp` and `ep` into the scope which is certainly not desired
21:41:02FromDiscord<Lefl> Is it possible to change the "do" to something like "fail"?
21:41:17FromDiscord<Lefl> I have no real idea how the templating works, I should get into that
21:43:43FromDiscord<System64 ~ Flandre Scarlet> newFileStrm.writeData(array8bits[0].addr, array8bits.len)↵Is it possible to write that in little endian mode?
21:44:23FromDiscord<Lefl> Uh it doesn't execute the `makeGetRequest` proc
21:48:02FromDiscord<ElegantBeef> It does so https://play.nim-lang.org/#ix=3pCu and no the `do` isnt apart of templates it's in nim's language and available for all procedures
21:48:23FromDiscord<ElegantBeef> You could write a macro for that but seems like a lot of work for very little benefit
21:50:19FromDiscord<Lefl> Hmm weird
21:50:32FromDiscord<ElegantBeef> To show that block param passing https://play.nim-lang.org/#ix=3pCv
21:51:03FromDiscord<ElegantBeef> Can be useful to eliminate pre calculating variables 😄
21:52:17FromDiscord<Lefl> I'm a big dummy
21:52:27FromDiscord<Lefl> I forgot to call the success procedure 😄
21:52:55FromDiscord<Lefl> Hmm wait no
21:54:35FromDiscord<Lefl> nvm it did work

22:03:56FromDiscord<exelotl> @System64 ~ Flandre Scarlet in Nim `/` always returns a floating point value. You want `a div 256` instead.
22:08:09FromDiscord<System64 ~ Flandre Scarlet> Ah alright
22:11:45FromDiscord<Hi02Hi> isn't it impossible for b > 255?
22:12:40FromDiscord<Hi02Hi> uint16.high = 2^16 - 1 = 65535↵65535 div 256 = 255

22:27:07FromDiscord<Alea> openarray is meant for taking unknown length arrays and seqs right?
22:27:37FromDiscord<Lefl> Does someone know how I can concatenate a cstring and a string?
22:29:47FromDiscord<konsumlamm> In reply to @matf "👋 curious how much": fwiw, i've rarely, if ever, seen it being used by anyone (though that doesn't need to be representative)
22:30:07FromDiscord<konsumlamm> In reply to @Lefl "Does someone know how": convert one to the other and then concatenate as normal?
22:31:29FromDiscord<konsumlamm> In reply to @Alea "openarray is meant for": i think the conversion doesn't happen through `ref`, i.e. `ref array[0..9, float]` doesn't get coerced to `ref openArray[float]`
22:32:00FromDiscord<konsumlamm> that's because `openArray`s aren't first class, but that may change in the future
22:32:50FromDiscord<Alea> I've ditched the ref for now in favor of just returning the array, but now I'm wondering if there some openarray equivalent for returns?
22:33:02FromDiscord<Alea> is returning an unknown length array allowed?
22:33:13FromDiscord<Alea> or do I have to use a seq for that
22:37:40leorize[m]you need a seq, but what are you trying to do?
