00:10:29FromDiscord<pmunch> Those where a good mix of copy paste from other languages and guesswork from my side. If they're incorrect please create a PR to fix them \:)↵(@Cloudperry)
00:20:54FromDiscord<Elegantbeef> Hey pmunch i've got to ask how does one properly serialize using your protobuf library?
00:27:11*src quit (Quit: Leaving)
00:50:15FromDiscord<pmunch> What do you mean?
00:50:27FromDiscord<Elegantbeef> Looking at it further it seems you only have the streamwrite method
00:50:44FromDiscord<DMI-1407> is there already a discord api for nim ?
00:50:47FromDiscord<Elegantbeef> My friend tried it yesterday and suffice to say he ran into a fair bit of issues
00:50:52FromDiscord<Elegantbeef> Dimscord yep
00:51:43FromDiscord<pmunch> Ah yes, it's built around streams
00:52:34FromDiscord<pmunch> So you parse your spec, create your object, and then write it to a stream
00:52:37FromDiscord<Elegantbeef> It does have a nice bug with nested empty messages aswell, though I've got a fix
00:53:14FromDiscord<Elegantbeef> Questioning whether i should clean up these macros though since it's very hard to read
00:56:38FromDiscord<pmunch> Oh yeah, they definitely need a cleanup..
00:57:05FromDiscord<pmunch> I believe protobuf was my first major macros project
00:57:13FromDiscord<Elegantbeef> Well there just made a PR for you
00:58:46FromDiscord<Elegantbeef> Yea i can really tell you used `astGenRepr` a lot 😛
00:59:51FromDiscord<Elegantbeef> Now to think of it, i've never used `astGenRepr` for anything but testing if logic is sound
00:59:52FromDiscord<pmunch> Haha, yup. I think that was actually what I wrote 'astGenRepr' for 😋
01:00:16FromDiscord<Elegantbeef> Oh you wrote `astGenRepr` for the stdlib?
01:00:24FromDiscord<pmunch> Yup
01:01:04FromDiscord<pmunch> I think I wrote it for protobuf, then realized it was probably a bad idea and barely ever touched it again 😅
01:01:37FromDiscord<pmunch> Then someone wrote \`quote\` which is a way nicer solution
01:01:44FromDiscord<Elegantbeef> It does what it promises but produces heavily unmaintainable macros
01:02:06FromDiscord<pmunch> Of course \`astGenRepr\` still has its uses, but not nearly as many after quote came along
01:02:14FromDiscord<Elegantbeef> quote/genast and the less verbose procedures are just nicer
01:02:29FromDiscord<Elegantbeef> well with genast i thinkg astgenrepr is mostly just a debug tool
01:02:54FromDiscord<pmunch> I then of course wrote superQuote in macroutils after that failed to get merged into Nim
01:02:55FromDiscord<Elegantbeef> You can now easily inject symbols/generate them
01:03:37FromDiscord<Elegantbeef> Given how much time i spend toying with macros it's kinda funny the only thing i've written to make it easier is a toy that is pointless
01:05:23FromDiscord<pmunch> Hmm, what's genast?
01:05:47FromDiscord<Elegantbeef> A new module in 1.6 that gives an alternative to quote removing many issues
01:06:01FromDiscord<pmunch> I wrote macroutils to try and fix a lot of the gripes I've had with writing macros over the years
01:06:05FromDiscord<Elegantbeef> Instead of making temporary variables before you just do `genAst(name = ident"ThisisAName")`
01:06:33FromDiscord<Elegantbeef> Now inside the scope `name` is the right hand of the `=`
01:06:34FromDiscord<pmunch> Then of course I've gotten so used to the old way of writing macros I couldn't really get used to using macroutils
01:06:47FromDiscord<Elegantbeef> It doesnt require accquoting either
01:06:50FromDiscord<pmunch> But it does have some nice tools, like superQuote
01:08:14FromDiscord<pmunch> Wait, so that's just \`let name = "ThisIsAName".ident\`?
01:11:00FromDiscord<pmunch> But I'm going to bed now
01:11:31FromDiscord<Elegantbeef> I mean it works like quote do but you can inject variables through parameters instead of capturing all variables in scope
01:11:43FromDiscord<Elegantbeef> so in the above case it finds `name` an replaces it with the right hand

02:17:16FromDiscord<Elegantbeef> done it but said jovial
02:17:36FromDiscord<valerga> running a nim binary seems to take at least 50ms, even on empty code, is that normal?
02:17:45FromDiscord<Elegantbeef> Nope
02:17:55FromDiscord<Elegantbeef> is this a release program?
02:18:27FromDiscord<valerga> https://media.discordapp.net/attachments/371759389889003532/919412853419679784/nimtime.jpg
02:18:30FromDiscord<valerga> that's release on empty code
02:18:44FromDiscord<valerga> im counting usr time
02:18:45FromDiscord<Elegantbeef> Are you compiling the binary and running it or counting the compil time?
02:18:56FromDiscord<valerga> i ran in twice
02:19:07FromDiscord<Elegantbeef> That doesnt answer my question
02:19:15FromDiscord<Elegantbeef> Are you actually timing the binary or the compiler?
02:19:19FromDiscord<valerga> ohh
02:19:26FromDiscord<valerga> i thought since it was cached it would just run it straight
02:19:37FromDiscord<valerga> i'll check the binary
02:19:38FromDiscord<Elegantbeef> Well it has to make sure it has no file changes
02:19:51FromDiscord<Elegantbeef> Which requires some computation
02:19:57FromDiscord<valerga> yeah it runs in 2ms
02:20:23FromDiscord<Elegantbeef> There we go that's a bit more reasonable since it has to set everything up and talk to the OS
02:20:57FromDiscord<valerga> 1ms on empty code
02:22:19FromDiscord<huantian> man I was looking at pull #11992 and started down the rabbit hole of random issues and pull requests that have a lot of text
02:23:36FromDiscord<Elegantbeef> Ah yes that's a fun PR
02:25:14FromDiscord<huantian> wonder if that'l ever get merged...
02:25:40FromDiscord<Elegantbeef> probably not
02:26:17FromDiscord<Elegantbeef> To me it seems like a big "Work around the problems instead of fix them"
02:27:16FromDiscord<huantian> but writing `.toSeq` before my maps is so much work!
02:27:17FromDiscord<evoalg> Sometimes I have to check that a condition isn't true for everything in a container. In python I would use a for-each trick, but in nim I'd do it like this I guess: https://play.nim-lang.org/#ix=3HM1 ... not sure if it's the best way?
02:27:56FromDiscord<leorize> try sequtils.all?
02:28:03FromDiscord<evoalg> this is a simple example, but in reality it would be complicated so I can't use all or any
02:28:05arkanoidwhat's better "static: var ..." or "var {.compiletime.}" ?
02:28:47FromDiscord<evoalg> unless I put it in a proc, then I could use "all" I guess?
02:28:52FromDiscord<leorize> would allIt work then?
02:29:16FromDiscord<leorize> same as all but you don't have to make a proc
02:29:49FromDiscord<huantian> you could always use an anonomous proc or sugar ->, or just use allit
02:30:01FromDiscord<huantian> (edit) "->," => "+>,"
02:30:04FromDiscord<huantian> (edit) "+>," => "=>,"
02:30:57FromDiscord<Elegantbeef> Also why the hell are you using `discard """` we have multiline comments?!
02:31:03FromDiscord<evoalg> I mean in a real programing there are many lines and it get's complicated to use all / allIt (or not very readable), but if I put the many lines in a proc then I could use all or allIt and it would still be readable, true
02:31:16FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=3HM3

17:10:08arkanoidwhere can I read how iterator works? I'm playing with inline and closure iterators and I'd like to understand how (and if) they can be used together
17:10:14FromDiscord<Rika> your l is not mutable
17:10:17FromDiscord<Solitude> In reply to @coldfussion "Probably, I currently have": https://nim-lang.org/docs/manual.html#procedures-var-parameters
17:10:40FromDiscord<Rika> arkanoid inline iterators do not exist on runtime (of course, because theyre inlined)
17:10:51FromDiscord<Rika> closure iterators can be halted and resumed at will
17:11:06FromDiscord<Rika> at the expense of memory and speed
17:11:24FromDiscord<pmunch> Well, not quite "at will"
17:11:43FromDiscord<coldfussion> Oh, thank you↵(@Solitude)
17:14:24FromDiscord<coldfussion> the type mismatch error message is quite a bit misleading tbh...
17:14:48arkanoidyeah, I quite nicely fit closure iterators with other programming patterns I tend to use in different languages. But inline iterator are another kind of beast. Also, what is type Iterable and when can/should use it?
17:15:50FromDiscord<Solitude> In reply to @coldfussion "the type mismatch error": its intentional, to drive more people to chat
17:16:54FromDiscord<0ffh> how can i do a reinterpreting cast between signed and unsigned integers?
17:17:12FromDiscord<Rika> cast
17:17:19FromDiscord<Rika> cast is reinterpret cast
17:18:31FromDiscord<0ffh> hum, i must have effed it up somehow, i get value out of range. but if iÄm on the right track with cast, i suppose i'll figure it out through the docs. thanks!

17:21:04FromDiscord<azazello> In reply to @Solitude "you didnt specify generic": it appears to work if I define the Matrix size↵would it be possible for it not to be known during init?
17:21:22FromDiscord<azazello> (edit) "it" => "the parameters" | "the parametersnot to be known during init? ... " added "assume not"
17:21:35FromDiscord<Solitude> no, arrays have statically known size
17:21:46FromDiscord<Solitude> if you dont know the size, why are you using arrays?
17:22:12FromDiscord<azazello> make sense, could use seq (just learning nim, for aoc!)↵thanks for your help
17:22:44FromDiscord<Solitude> good read https://nim-lang.org/docs/tut1.html
17:49:00arkanoidcould you please give me an example where I can use iterable[T] type? https://nim-lang.org/docs/system.html#iterable
17:50:24arkanoidit's defined as type iterable*[T] {.magic: IterableType.} and I'm trying to figure out what's the intended use. It's not a type alias of "iterator(): T" but the doc says that "Represents an expression that yields T"

21:14:33FromDiscord<Professor Actual Factual> Anyone know of a good way of managing memory-related as side-effects? I know there was some discussion surrounding this topic on the forum a while back. Having a pragma like `{.noAllocations.}` would be great IMO. If the stdlib doesn't provide this, thats fine. How can I implement my own solution?
21:14:50FromDiscord<Yardanico> you can create your own tag and tag your functions
21:14:57FromDiscord<Yardanico> https://nim-lang.org/docs/manual.html#effect-system-tag-tracking
21:21:11*noeontheend quit (Ping timeout: 268 seconds)
21:22:28arkanoidProfessor Actual Factual, interesting feature, but it would require to tag all procs that allocates memory beforehand. Not sure if there's an automatic way to do that, but one idea could be to create a pragma to wrap a function and runs getOccupiedMem() as first and last op and saves the results to a log file if it differs, then use this info for further analysis
21:23:03*nrds quit (Remote host closed the connection)

21:44:10*jjido quit (Quit: My MacBook Air has gone to sleep. ZZZzzz…)
21:46:12FromDiscord<Yardanico> In reply to @SivadNai "can somebody remind me,": can you try doing `echo repr mystr`
21:46:16FromDiscord<Yardanico> it'll show the spaces and all stuff
21:46:22FromDiscord<Yardanico> if it's just spaces you can use `strip` from `strutils`
21:50:13arkanoidcould you please explain me here why proc returns error but template does not? https://play.nim-lang.org/#ix=3HUo
21:50:59FromDiscord<Yardanico> because iterable[T] currently only works with templates
21:51:14FromDiscord<Yardanico> don't ask me for the reason, i'm not the one who made it that way
21:51:40FromDiscord<SivadNai> to take a different line in the output, '000000000017F960"\01\07\06\03\02\0"↵invalid integer: 17632`
21:52:04FromDiscord<Yardanico> In reply to @SivadNai "to take a different": i think it might be an xy problem and you're actually getting your string in a wrong way from somewhere
21:52:07FromDiscord<Yardanico> how are you getting this string?
21:52:26FromDiscord<Yardanico> sure you can "clean" all the non-printable characters, but I think the problem is in the way you get that string
21:52:29arkanoidFINALLY I got my answer. Thanks yardanico, I've been playing a lot around this today and I couldn't undertand. The manual doesn't say that afaik
21:53:16FromDiscord<Yardanico> @arkanoid see the original pr https://github.com/nim-lang/Nim/pull/17196
21:53:26FromDiscord<SivadNai> it's a bat file which calls a powerhshell `Get-CimInstance Win32_Process -Filter "name = 'Code.exe'" | select ProcessId , CommandLine | Format-Table -AutoSize -Wrap > Code.txt`
21:53:57FromDiscord<Yardanico> very weird, but yeah, you can clean that null byte
21:54:08FromDiscord<Yardanico> but i really think that you shouldn't be getting a null character here
21:54:11FromDiscord<SivadNai> so I didn't expect to get some strange format error like that
21:54:14FromDiscord<Yardanico> and how do you get it in nim ?
21:54:17FromDiscord<Yardanico> just reading the file?
21:54:30arkanoidYardanico: how did you find this pr so fast? I've been using advanced github search for a while looking for something like this
21:54:42FromDiscord<Yardanico> because iterable[t] has been discussed previously
21:54:46FromDiscord<Yardanico> multiple times
21:54:57FromDiscord<Yardanico> about other people being confused why it only works with templates
21:55:25FromDiscord<SivadNai> yes, just going over `for line in lines "Code.txt":`
21:55:55FromDiscord<Yardanico> then you can use https://nim-lang.org/docs/strutils.html#strip%2Cstring%2Cset%5Bchar%5D with `chars` set to `{'\0'}`
21:56:08FromDiscord<Yardanico> but as I said, try to actually find why it's adding a null byte here

21:57:19FromDiscord<Michal58> what is the best way to create an array full of some constant (different from zero)?

21:57:37FromDiscord<SivadNai> thanks, I will try that. I'd already stripped Whitespace
21:57:44FromDiscord<Yardanico> but it's not "creating" it with some value, but actually filling after creating
21:57:58FromDiscord<Yardanico> the proc itself just does a simple loop really
21:59:55FromDiscord<Michal58> thanks
22:16:23FromDiscord<huantian> In reply to @Yardanico "don't ask me for": Isn't it something something iterables aren't actually first class objecs?
22:20:43arkanoidhuantian, inline iterators are something, closure iterator are something else. Closure iterators are first class afaik

23:51:25FromDiscord<Elegantbeef> https://play.nim-lang.org/#ix=3HUQ
23:51:27FromDiscord<Elegantbeef> Look where the data is
23:52:09FromDiscord<Elegantbeef> The `doStuff` method shares address which means it moves it fine, but the block method doesnt which means it deep copies the string
23:55:07FromDiscord<AmjadHD> Thanks, so isn't this an oppotunity for optimaization ?
23:55:43FromDiscord<AmjadHD> (edit) "optimaization" => "optimization"
23:58:23FromDiscord<AmjadHD> In reply to @Elegantbeef "The `doStuff` method shares": many templates and macros use a similar code, it would be wasteful to copy the block's returned expression.
