05:35:55Zevvkrab4t: That's one way to do it. You can also let NPeg do the capturing for you into a AST or JSON tree.

05:56:31FromGitter<zacharycarter> @gogolxdong I think you'd have to remove it from b as well
05:57:47FromGitter<zacharycarter> I'm guessing that `var b = a + {3}` creates a new hash set
05:58:47FromGitter<zacharycarter> https://github.com/nim-lang/Nim/blob/version-1-0/lib/pure/collections/sets.nim#L391 - which is what `+` is equivalent to
06:01:43FromGitter<gogolxdong> yes, it could , assuming there is a deep level set structure, excl from each is unrealistic .It's easy if there is elements shallow copy or becoming ref type.
06:03:47*rockcavera quit (Remote host closed the connection)
06:07:09FromGitter<gogolxdong> new hash set is created on assigning like other value type in Nim. In this context, elements of sets better be ref type.Is is possible?

07:56:18FromGitter<alehander42> araq
07:56:26FromGitter<alehander42> should we check for distinct ref types
07:56:30FromGitter<alehander42> or does it not make sense
07:56:39FromGitter<alehander42> as one needs to cast them to ref anyway?
07:57:29Araqfor me 'distinct' is about hiding implementation details. if I have a 'distinct ref' I might want to change that to a 'distinct ID' later on
07:57:43Araqand so there is no 'new' for 'distinct ref' and it works as designed
07:59:00PMunchBut what about https://github.com/nim-lang/Nim/issues/9566
07:59:46FromGitter<alehander42> ok
08:00:04PMunchOh wait, yeah I see you are discussing an issue created when krux02 was trying to solve that one..
08:01:41FromGitter<alehander42> yes it reminded me should i wonder about them in nil checking
08:03:06Araqoh for the nil checking you can do skipTypes(abstractInst) which covers tyDistinct
08:03:18Araqit's not your job to care about 'distinct' in this pass
08:03:25FromGitter<alehander42> ah but i wonder if its possible
08:03:30Araqlet the frontend handle it
08:03:30FromGitter<alehander42> to deref a distinct ref at all
08:03:38FromGitter<alehander42> i couldnt think how
08:03:39FromGitter<alehander42> without cast
08:03:44FromGitter<alehander42> which should turn it to ref anyway
08:03:46Araqit shouldn't be possible but it's not your job to enforce it
08:03:50FromGitter<alehander42> ok

08:05:18PMunchHmm, there was a discussion on the forum I saw recently where someone created a "deref" macro. It would take a type declared as "type MyType = ref object" and get the un-named non-ref type to allow things like "type MyOtherType = distinct deref(MyType)" without having to create both the inner and outer type.
08:05:27PMunchMaybe that should be built in?

08:08:12AraqPMunch, I think krux02 had a really good solution for this via the new system.default(T)
08:08:36*Vladar joined #nim
08:09:20PMunchYeah the deref thing I'm thinking of used default
08:09:49PMunchI think it was something like default(T) and then grab the inner type from the getImpl or something like that.
08:11:14krux02template deref[T](arg: typedesc[ref T]): untyped = T
08:11:19krux02you mean that?
08:11:28krux02I think I called it unref
08:11:40krux02doesn't use default though
08:11:46*FromGitter quit (Read error: Connection reset by peer)
08:12:06*FromGitter joined #nim
08:12:32krux02it should be able to deref `MyType = ref object` as well
08:12:33PMunchThis is the one I was thinking of: https://forum.nim-lang.org/t/5343#33492
08:13:19PMunchBut yeah, I guess they do pretty much the same thing
08:21:33FromDiscord<krab4t> Zivv: i just don't get it how to assign every new ` section ` (in example grammar you linked before) into new object, i can't create new objects inside grammar

08:38:40narimiranthanks for testing it @Vindaar!
08:39:07FromGitter<Vindaar> always glad to be of service ;)
08:40:59FromDiscord<krab4t> hm, i did almost the same, wait i forgot to create vars before grammar rip
08:41:37FromDiscord<IJCSTAB> for i in 0 .. <fileSize:
08:41:37FromDiscord<IJCSTAB> file.setPosition(i)
08:41:37FromDiscord<IJCSTAB> discard file.readData(buff.addr, 1)
08:41:37FromDiscord<IJCSTAB> outSeq.add(buff)
08:41:37FromDiscord<IJCSTAB>
08:41:38FromDiscord<IJCSTAB> pretty ugly code but i'm so confused as to why this takes nearly 3 seconds to read a 4MB file on an NVME SSD
08:42:07FromDiscord<IJCSTAB> doing the same thing runs substantially faster in Python
08:46:26lqdev[m]solution: read more data at a time
08:46:42lqdev[m]instead of reading 1 byte do it in batches of 1024 bytes
08:47:04lqdev[m]also, don't do file.setPosition like that
08:47:11lqdev[m]it's slow
08:47:27narimiran...and pre-allocate your `outSeq`: `var outSeq = newSeq[byte](filesize)`
08:47:33lqdev[m]just do readBuffer and you'll be fine
08:48:19PMunchAnd please, next time you want to send us code, don't paste it directly into Discord, use a paste service

10:35:43Araqthere is a nimble package to do that...
10:36:02Araqand then there is: let d = unsafeAddr(...)
10:36:33sealmovehmm, I'll fiddle with unsafeAddr, see if it does the job, ty
10:37:52*theelous3 quit (Ping timeout: 264 seconds)
10:38:51Araqthere is also the "helper proc taking a 'var T' parameter" trick
10:38:52sealmovebtw Araq, I am confused as of how exactly `var` works in parameter list
10:39:22sealmovefor example I noticed when the type is a ref object, then I can modify it in a proc without `var` type anotation
10:48:19sealmovehmm, without `var`, it means I can't change the argument to point to a different object, but I can change the object it points to, like `T *const x` and unlike `const T *x` in C.
10:49:23sealmovewhat is the equivelant of `const T *x` in Nim?
10:54:07sealmove(being able to modify the argument so that it points to different object, but prohibiting modification of the object it points to)
10:54:49sealmoveis it possible?
10:56:44alexander92i was confused for that too for some time, i did put var everywhere
10:57:43alexander92and what is "const ref which cant be changed"
10:57:51alexander92const T *const x
10:57:53alexander92?
10:59:14sealmove`ref x` <=> `T *const x`
10:59:29sealmove`var ref x` <=> `T *x`
10:59:39sealmoveI think Nim only have semantics for these 2
10:59:39alexander92thank you!
10:59:45alexander92helpful mapping
10:59:48alexander92hm, but what is it in C?
11:00:01alexander92sorry, i meant
11:00:25*NimBot joined #nim
11:00:45sealmoveyes, `const T *const x` means you can't change the object it points to, neither the value of the object
11:00:54alexander92is it often used in C?
11:01:05sealmoveyes
11:01:08alexander92seems useful for some readonly cases
11:01:10alexander92ok
11:01:48sealmoveI guess `const T *x` is not used as often (not sure though)
11:01:53FromDiscord<krab4t> npeg throws out of range instead of just maybe 0 as value
11:02:02alexander92https://forum.nim-lang.org/t/4704
11:02:09alexander92wow, this is old
11:02:21alexander92oh no, i thought its 2008
11:02:23alexander92nvm :P
11:02:32sealmovelol
11:04:02sealmovealex nice, I think this thread hits the point
11:08:52alexander92it seems deep immutability is hard indeed
11:08:59alexander92but that c++ actually just does the symbol imm
11:09:22alexander92yeah basically repeating demotomohiro
11:11:39sealmovewow this thread is looooong
11:11:41sealmoveinteresting!
11:11:55Zevvkrab4t: are you trying to access captures that you didn't make? Your grammar has some optionals like the alpha on the colors or the optional operator (<=, >=) in various checks
11:17:05alexander92sealmovew
11:17:12FromDiscord<krab4t> yes these not existing captures
11:18:33alexander92sealmove look, i think they solve your question a bit
11:19:47sealmoveindeed, after reading through a bit, I realized C's solution (weak immutability) is not the only way to model things.
11:20:01Zevvkrab4t: check `capture.len` before accessing, so you can tell how many you did actually capture there. Maybe I should not throw there but return an empty string, I'm not sure yet
11:22:38sealmove"strong immutability cannot be achieved at compile time" "Strong immutability might be possible without any runtime check/cost by copying rust's ownership"
11:30:26sealmoveso strong immutability might not be ideal (almost certainly it can't be done without adding mental overhead to the programmer)
11:31:16sealmovebut having syntax for `const T *x` and `const T *const x` could be solved
11:33:30Araqwhat's the point in solving it? use 'x: T' in Nim for parameter passing
11:34:18Araq"give me a pointer to this data and I promise not to modify it" is backwards, don't use a pointer to begin with.
11:34:45alexander92but what if it is a recursive type
11:36:39sealmoveAraq: ok this is fair enough for `const T *const x`, not needed, but `const T *x` (being able to change the pointing but not the data) is useful, no?
11:37:47PMunchAraq, what is the correct way of loading some data at the begining of a Karax application? I want to load a list from the server and put it on the site as soon as it is ready.
11:38:42PMunchJust adding it to the body before the setRenderer call didn't really work
11:39:08PMunchIt completes after the renderer is done, so it won't show up until something changes
11:39:58Araqsealmove, how so?
11:40:49Araqit doesn't come up all that often, if it does, use 'var needMut = unsafeAddr(myParam)'
11:40:55PMunchNever mind, got around it with some logic in postRender
11:40:58Araqinside the proc
11:41:11AraqPMunch, ok, I don't have an answer
11:41:17PMunchBy the way, how does Karax know when a variable changes?
11:41:33sealmoveAraq: I see, makes sense now, thanks
11:41:35Araqit doesn't it redraws after an event
11:41:52PMunchAh okay, that's what I suspected

12:55:11FromDiscord<krab4t> @ZeeQyu open 10 tabs full of gifs
12:55:25PMunchNow the script that runs things is the same, and it call the executable "nim"
12:55:58PMunchBut looking at your screenshot I can see the compilation target and the version selector having popped down a line..
12:56:20FromDiscord<Rika> another fun fact 100 incognito tabs has a \;\) afaik
12:56:22PMunchI guess I didn't test it at that low screen resolutions..
12:57:01FromDiscord<ZeeQyu> I see. Would it be as simple as to rename the executable after building?
12:57:14PMunchZeeQyu, what is the resolution of your screen by the way?
12:57:23PMunchZeeQyu, hmm possibly
12:58:36FromDiscord<ZeeQyu> My "about phone" says 1080x1920 but I'm guessing chrome emulates a smaller one. Don't know how to find out though. Huawei Honor 8 FRD-9 something
12:58:58FromDiscord<ZeeQyu> FRD-L09
12:59:23livcdPMunch: can i get intellij in playground ? :D
13:00:06FromDiscord<Rika> lmao
13:00:26FromDiscord<Rika> PMunch afaik sites scale by DPI not just resolution
13:00:32alexander92with some wasm builds
13:00:33alexander92maybe
13:01:12alexander92pmunch we can have a jsfiddle-like view for the javascript
13:01:13FromDiscord<ZeeQyu> If I choose "Desktop site", I get this, so I don't think it's a caching issue on my end.

13:02:21PMunchZeeQyu, yeah I'm looking into it right now
13:02:31PMunchlivcd, no..
13:02:48FromDiscord<Rika> is there even a decent intellij plugin for nim
13:02:53livcdPMunch: pretty please
13:03:02PMunchIf you can get nimlsp to compile on the JS target I'll look into integrating it with CodeMirror :P
13:03:28PMunchalexander92, jsfiddle-like?
13:03:46alexander92a very popular similar playground
13:03:48alexander92https://jsfiddle.net/
13:04:38FromDiscord<ZeeQyu> @Rika Working on it, actually. Don't have much free time, currently learning JetBrains's plugin API.
13:04:45FromDiscord<ZeeQyu> But I'll get there
13:04:53FromDiscord<Rika> youre making me excited
13:04:55FromDiscord<Rika> dont do this to me
13:04:56alexander92but its just a fun idea, people dont use it
13:05:04FromDiscord<ZeeQyu> I hoped I would.
13:05:07alexander92so often that we need that
13:07:57FromDiscord<ZeeQyu> I'm slightly scared I have to reimplement the lexing and parsing in their interface, and not be able to use nimsuggest. They have a particular structure in mind, which is great for when there's no external parser, don't get me wrong, but which is fairly locked down, and I have yet to figure out if there's a way around it.
13:11:28sealmoveis there a proc for reading from a file from a particular position? or I have to seek() and read() seperately?
13:20:48PMunchZeeQyu, when the cache for the playground stylesheet updates your issue should be fixed :)
13:21:29PMunchalexander92, I know what jsfiddle is, but what exactly did you want from it?
13:21:52PMunchOh, you wanted to see Nim output as JS on the website like HTML?
13:23:39FromDiscord<juan_carlos> Python users are celebrating they got 1 new operator, and I am like lol ๐Ÿ˜
13:25:05PMunchHaha, which operator?
13:25:20narimiran:=
13:25:32narimiranso called walrus operator
13:26:47PMunchHaha, interesting name
13:26:58PMunchWhat does it do?
13:27:11narimiranit makes half of pythonistas happy and the other half angry
13:27:14FromDiscord<juan_carlos> They kicked the creator of the lang out because of `:=`
13:27:32narimiran@juan_carlos how about not spreading fake news?
13:27:42FromDiscord<juan_carlos> Yes, some people really angry some people really happy over that operator.
13:28:28FromDiscord<juan_carlos> I mean not that, but it was one of the things that sums up, to it. The release literally has commits from him.
13:28:35livcdIs it the same like in Go ?
13:28:46FromDiscord<juan_carlos> Similar to Go.
13:29:20narimiranlivcd, PMunch: see here: https://docs.python.org/3.8/whatsnew/3.8.html#assignment-expressions
13:29:22PMunchWhat does it do in your code? :P
13:29:47PMunchAaah
13:30:31FromDiscord<juan_carlos> Right now no one should have it, but sure it breaks lit of parser, regexes, syntax highlight, etc.
13:32:58FromDiscord<juan_carlos> Theres linters made to ban the `:=`
13:33:03PMunchHmm, I'm getting a weird error from jesters..
13:33:11FromDiscord<juan_carlos> So I guess some people are not happy at all.
13:33:33PMunchIt says that it replies with 200 OK, but then it crashes

13:37:17PMunchWhat do you mean race=

13:39:19FromDiscord<juan_carlos> sleep 1 second after it writes it, and see if still does the same, maybe the OS has it open for some reason.
13:40:09PMunchThat is not the issue here, it's not trying to read or write to /tmp/test..
13:40:24PMunchnim c -r test.nim creates the file test
13:40:51PMunchThe error I'm guessing is from the socket that it tries to send the reply over
13:41:11PMunchThe other end get's an error that "Remote end closed connection without response"

14:21:46disruptekno, you're right, seek is the wrong word.

15:18:54FromDiscord<ZeeQyu> The new python operator is very pythonic. It's foreign and eccentric to people when first introduced, creates elegant code and is actually a really nifty idea when you get used to it, and makes very many people upset to the point of irrationality.
15:22:11FromDiscord<juan_carlos> The problem I see is that they dont add it into `__future__` then you basically break everything from `3.0` to `3.7`, thats the reason of the anti-walrus linters.

17:00:56FromDiscord<Rika> i'm completely baffled by nimPNG; anyone know either how to use nimPNG or an alternative?
17:02:30FromGitter<zetashift> the docs seem quite okay for such a library, what is the showstopper?
17:03:18FromGitter<zetashift> https://github.com/jrenner/nim-simplepng seems to be an alternative tho
17:05:05FromDiscord<Rika> zetashift: i cannot for the life of me understand how pixels should be read
17:07:11*alexander92 joined #nim
17:08:14FromGitter<zetashift> I don't know much about nimpng either but the readme might give a hint in: `pixels are stored as raw bytes using Nim's string as container`
17:08:50FromDiscord<Solitude> @Rika https://github.com/SolitudeSF/imageman plugging my lib, hoping you can understand it
17:09:19FromDiscord<Rika> ooh more formats, does it support PNG grayscale 4bit?
17:09:51FromDiscord<Solitude> it wraps stb_img, does it support it?
17:10:03FromDiscord<Solitude> *stb_image
17:11:01FromDiscord<Rika> stb image shows it can do 4bit but not what color modes
17:11:27FromDiscord<Solitude> im gonna put it in my todo list
17:11:33FromDiscord<Rika> okay it shows it can do grayscale
17:13:02FromDiscord<Rika> regarding nimpng: when i dump the whole contents of {image}.data (image is 2 by 2 picture), i get a whole lotta bytes
17:13:13FromDiscord<Rika> i feel like that its not supposed to give me that many
17:13:48FromDiscord<Rika> did image.data.len, got the number 250,000
17:14:21FromDiscord<Rika> whilst my image is 1,821 bytes large
17:14:45FromDiscord<Solitude> maybe it upconverts it to rgba
17:14:56FromDiscord<kodkuce> https://play.nim-lang.org/#ix=1YKM << am i a monogoloid or is it giving wrongfully 51 when there only 10 items in seq?
17:17:52FromGitter<iffy> I'm guessing GC_unref should be called from the same thread that GC_ref was called from?
17:18:53narimiran@kodkuce: this should give you a hint: https://play.nim-lang.org/#ix=1YKQ
17:20:22FromDiscord<Rika> tell us if you cant figure it out
17:26:10FromDiscord<Rika> realized that nimpng is giving me a few hundred bytes of \{i}, increments i, then gives me a few hundred bytes of that

20:22:03FromGitter<zacharycarter> is there a way to specify which compiler to use for the compile pragma?
20:22:20FromGitter<zacharycarter> or I guess it just uses the compiler that the source is being compiled with?\
20:22:23FromGitter<zacharycarter> that probably makes more sense
20:24:24FromGitter<zetashift> Why wouldn't it? Sounds weird to let vcc compile a part with gcc?
20:24:55FromGitter<zacharycarter> yeah
20:24:58FromGitter<zetashift> (I could also be understanding your intention wrong)

20:40:24Zevvyou're having quite a fight there
20:40:53rayman22201fight? or "lively academic discussion" :-P
20:41:11disruptekoh shoot, i've had my head down and now i'm missing another async duel?
20:41:28rayman22201I love to argue, I was on the debate team in high school lol. I could have been a lawyer lol
20:42:08rayman22201I don't think it's nearly as serious as the other one. I'm just a blabbermouth. I don't know how to be succinct :-P

21:03:35rayman22201@disruptek, #12431 is weird but I get Araq's position I guess? I think it actually gets rewritten in the compiler pass into what Clyybber wrote. That might be the wrong thing to do though. :thinking:

22:12:13superbiawhich data structure should I look at, and also how does duplicate notification work?
22:13:51FromGitter<awr1> @zetashift a use case for multiple compilers: generating ISPC code from nim and compiling it seperately, see https://ispc.github.io/
22:15:01FromDiscord<Kiloneie> i changed all thumbnails
22:15:28FromDiscord<Kiloneie> but imma change them again tomorrow, too much empty space in the middle, upp the font ,top right and top left closer together.
22:27:01rayman22201@superbia you want to use set: https://nim-lang.org/docs/sets.html
