01:35:10FromDiscord<Elegantbeef> `optHighlight in c.options`
01:35:14FromDiscord<Elegantbeef> Or whateve
01:36:18FromDiscord<Nilts> In reply to @Elegantbeef "`optHighlight in c.options`": It was presented as a compiler flag, that is why i was confused
01:36:27FromDiscord<Nilts> and what is c
01:37:11FromDiscord<Elegantbeef> `config`
01:37:14FromDiscord<Elegantbeef> It's a config
01:37:31FromDiscord<Elegantbeef> Search for `in c.options` or similar in the repository you'll find a reference
01:39:41FromDiscord<Nilts> In reply to @Elegantbeef "`config`": I am still confused, Is it a compiler option? I know how to do it if it is a generator option.
01:41:18FromDiscord<Elegantbeef> It's a compiler option
01:41:24FromDiscord<Elegantbeef> `nim doc` is the compiler still
01:41:34FromDiscord<Nilts> In reply to @Elegantbeef "`nim doc` is the": I am not using nim doc
01:41:35FromDiscord<Elegantbeef> You need to add the option and handle it afaik
01:42:34FromDiscord<Elegantbeef> Oh this is for rstgen
01:42:55FromDiscord<Nilts> In reply to @Elegantbeef "Oh this is for": yes, ig that is why what you are saying is confusing

05:54:32FromDiscord<Elegantbeef> Nope
05:57:12FromDiscord<Elegantbeef> Async is non blocking assuming you have a some sort of `await` or similar place in your code to give up your cpu
05:57:26FromDiscord<Arathanis> async is cooperative multitasking
05:57:43FromDiscord<Arathanis> await = someone else can run (maybe)
06:14:54FromDiscord<Arathanis> with taht said, how would you kick off parallel tasks in nim's async and then wait for the collection of futures?
06:15:15FromDiscord<Arathanis> (edit) "async" => "asyncdispatch"
06:15:21FromDiscord<Arathanis> (edit) "futures?" => "futures to complete?"
06:16:51FromDiscord<Rika> you call the procs that give futures without await, store their values into a seq (lets call it `futures`), and then after that you do `await all futures`
06:16:59FromDiscord<Rika> thats the code yes, `await all futures`
06:17:12FromDiscord<Arathanis> all must be a proc or something?
06:17:14FromDiscord<Rika> yes
06:17:20FromDiscord<Rika> i think its in asyncfutures
06:17:22FromDiscord<Rika> the module
06:17:28FromDiscord<Rika> which is exported by asyncdispatch
06:17:29FromDiscord<Arathanis> `await(all(futures))`
06:17:32FromDiscord<Rika> yes
06:17:38FromDiscord<Arathanis> but since nim
06:17:39FromDiscord<Rika> it reads real nice lol
06:17:43FromDiscord<Arathanis> we can omit the ugly characters
06:20:26FromDiscord<Arathanis> thank you @Rika

06:21:11*azimut quit (Ping timeout: 255 seconds)
06:21:37FromDiscord<Arathanis> basically when a task is awaited control is given to the event loop which can choose to run a different task
06:21:54FromDiscord<Arathanis> await "freezes" the current task (async procedure) and gives control back to the event loop
06:22:32FromDiscord<Arathanis> so its cooperative multitasking, you have to explicitly return control to the event loop, cause until you do you are in that execution path
06:22:43FromDiscord<Arathanis> the idea is that when you make a system call to perform some kind of IO
06:22:47FromDiscord<Arathanis> the Os is actually doing that
06:22:54FromDiscord<Arathanis> so you can run other tasks while waiting on the OS to make that call
06:23:12FromDiscord<Arathanis> (edit) "make" => "execute" | "call" => "system call, like writing to a file"
06:23:36FromDiscord<Dudugz> lol i know how async works tho. That's not the point, if you make an async function in Javascript with an infinite while loop and call the function it won't block the rest of the code. In Nim doing what I demonstrated above blocks, echo will never be executed
06:23:54FromDiscord<Arathanis> that's because javascript is always async all the time
06:24:19FromDiscord<Arathanis> you have to set up that boilerplate yourself in nim
06:24:24FromDiscord<Arathanis> ie: put the echo in a different task
06:24:28FromDiscord<Arathanis> and explicitly call it
06:25:06FromDiscord<Dudugz> It's not... Javascript runs in a separate thread yes but async is a feature that came with ES6, if you don't create a module type script it will continue to work synchronously
06:26:52FromDiscord<Dudugz> But I understand, in this case I would have to use threads to be non-blocking? Because asyncCheck in theory should already execute the asynchronous function without blocking
06:27:20FromDiscord<Elegantbeef> I mean the issue is purely your while loop doesnt give up the cpu
06:27:29FromDiscord<Dudugz> Hm
06:27:32FromDiscord<Arathanis> when you call asyncCheck it gives the main thread over to the event loop
06:27:48FromDiscord<Arathanis> and wont terminate until that event loop closes, which is when the future returned by the task you called is complete
06:28:40FromDiscord<Elegantbeef> The way Nim's async work is when you do `await`, `waitFor`, `poll`, or any other operations that do it, you give up the cpu to work on other operations
06:28:47FromDiscord<Dudugz> Hm, is there an efficient way to make an infinite loop without blocking then?
06:28:56FromDiscord<Elegantbeef> So if you have a empty while loop there is no way to go back to your main thread
06:29:05FromDiscord<Arathanis> add "await sleepAsync(0)" to give control back to the event loop
06:29:14FromDiscord<Dudugz> In reply to @Elegantbeef "The way Nim's async": Got it, in this case the while loop will hold the cpu forever
06:29:19FromDiscord<Elegantbeef> Yes
06:29:26FromDiscord<Elegantbeef> I say main thread but i mean main body
06:29:34FromDiscord<Arathanis> you have to multitask "cooperatively"
06:30:04FromDiscord<Dudugz> Sure, i'll try. Thanks :3
06:31:01FromDiscord<Arathanis> take a look at my example above, it kicks off two loops that could be infinite
06:31:22FromDiscord<Arathanis> and they both run cooperatively cause they both give control back to the event loop with an await during each loop body
06:33:28FromDiscord<Arathanis> sent a code paste, see https://play.nim-lang.org/#ix=4tjI
06:33:46FromDiscord<Dudugz> Got it, 0 would do it too, right?
06:33:49FromDiscord<Arathanis> yes
06:34:01FromDiscord<Dudugz> Thx 😁
06:34:03FromDiscord<Arathanis> np
06:34:53FromDiscord<⚶ Zeno> In reply to @Rika "thats the code yes,": i didnt expect that code to be that self explanatory, damn
06:35:28FromDiscord<Arathanis> In reply to @Dudugz "Thx 😁": also if we want to be explicit and just generally cool you can do silly things like this
06:35:41FromDiscord<Arathanis> sent a code paste, see https://play.nim-lang.org/#ix=4tjJ
06:35:53FromDiscord<Arathanis> 😎
06:36:09FromDiscord<Dudugz> Yeah but no lol, it's just an unnecessary syntactic sugar
06:36:21FromDiscord<Arathanis> it most certainly is
06:36:37FromDiscord<Elegantbeef> Cant you do `await Future[void]()`... hmm
06:37:12FromDiscord<Elegantbeef> I do not use async so i'm uncertain
06:37:31FromDiscord<Dudugz> But wouldn't you have to create a future that completes immediately? It's basically sleepAsync(0)
06:37:37FromDiscord<Arathanis> sent a code paste, see https://play.nim-lang.org/#ix=4tjL
06:37:48FromDiscord<Elegantbeef> cant you also do `poll(0)`
06:37:58FromDiscord<Arathanis> (edit) "https://play.nim-lang.org/#ix=4tjL" => "https://play.nim-lang.org/#ix=4tjM"
06:37:59FromDiscord<Dudugz> I think so
06:38:05FromDiscord<Arathanis> also i wonder if i could port `trio` to nim đŸ€”
06:38:09FromDiscord<Arathanis> call it `trion`
06:39:30FromDiscord<Elegantbeef> trio?
06:39:43FromDiscord<Arathanis> In reply to @Elegantbeef "trio?": https://trio.readthedocs.io/en/stable/
06:41:22FromDiscord<Dudugz> I'm surprised that Beef doesn't use async >.> I mean, it's important for a lot of things.
06:41:35FromDiscord<Elegantbeef> Not so much for simple games or macros
06:42:09FromDiscord<Dudugz> Hmm, indeed for this kind of thing it doesn't really help
06:43:07FromDiscord<Elegantbeef> Not to say one cannot use io loading of assets and the like, but my game loads fast cause everything is so small
06:44:45FromDiscord<Dudugz> yea i think for bigger games the best strategy is to use async to load the files.
06:45:07FromDiscord<Dudugz> I like to mess around with networking a lot so async is always welcome

07:31:23FromDiscord<Rika> i didnt write much code yet on the idea
07:31:26FromDiscord<Arathanis> yeah it would need a lot
07:31:31FromDiscord<Arathanis> good on you for at least attempting

07:56:07FromDiscord<morgan> is there a way to have a type that contains an array and define that array at compile time? i might end up using a seq idk
07:56:50FromDiscord<morgan> not even sure i need a separate type actually
07:57:03FromDiscord<morgan> haven't started on the code yet
07:57:10FromDiscord<morgan> been working on the math
07:58:43FromDiscord<demotomohiro> In reply to @MorganAlyssa "is there a way": Something like `Foo[T: static[array[2, int]]]`?
07:59:18FromDiscord<morgan> oh as a generic
07:59:23FromDiscord<morgan> i hadn't thought of that
08:05:10FromDiscord<morgan> i might just use one big array, since i'd have an array of these smaller arrays
08:05:23FromDiscord<morgan> im not sure i'd gain anything from the array of smaller arrays
08:06:09FromDiscord<ringabout> In reply to @Isofruit "Ahhh check, so that": Hopefully it should fix the illegal assignment => https://github.com/nim-lang/Nim/pull/21660
08:06:36FromDiscord<morgan> i've been writing it like that so far, but a lot of the operations involve flipping it around or shifting it over a partial amount so it would probably just get in my way
08:09:25FromDiscord<Phil> In reply to @ringabout "Hopefully it should fix": Just got the mail notification!↔That is super cool, thank you very much!

08:12:39FromDiscord<Phil> Ah, runtime defect
08:13:20FromDiscord<System64 ~ Flandre Scarlet> Are seqs passed by reference or by copy?
08:14:39FromDiscord<Elegantbeef> by ref
08:14:51FromDiscord<System64 ~ Flandre Scarlet> Ah alright
08:14:51FromDiscord<Elegantbeef> Actually by copy
08:15:13FromDiscord<Elegantbeef> But it doesnt matter cause the data they point to is heap allocated
08:15:15FromDiscord<System64 ~ Flandre Scarlet> Oh wait↔That means if there is 2000 items, it will copy all 2000 items?
08:15:38FromDiscord<System64 ~ Flandre Scarlet> Like for example↔A seq of uint32
08:15:39FromDiscord<Elegantbeef> No
08:15:49FromDiscord<Elegantbeef> cause a sequence is not stack allocated
08:16:16FromDiscord<System64 ~ Flandre Scarlet> Oh alright↔It is the case in C too I think
08:17:58FromDiscord<Elegantbeef> Nim really doesnt make you have to think if something is passed by ref or copy
08:18:31FromDiscord<huantian> cow strings when
08:18:35FromDiscord<System64 ~ Flandre Scarlet> so I just pass the value, and Nim manages it for me?
08:19:30FromDiscord<Elegantbeef> You pass a sequence and cause a sequence is `len: int, data: ptr` it's fine
08:19:46FromDiscord<System64 ~ Flandre Scarlet> Oh alright
08:20:17FromDiscord<Elegantbeef> Nim literals are COW so checkmate↔(@huantian)
08:20:35FromDiscord<System64 ~ Flandre Scarlet> what are COW strings 🐼 🐄
08:28:49FromDiscord<Rika> Copy on write
08:29:02FromDiscord<Rika> The data is only duplicated or copied when a write is made
08:30:23FromDiscord<System64 ~ Flandre Scarlet> Isn't it a bit heavy?

11:28:03Amun-RaI'd go with uncheckedarray

13:35:41FromDiscord<System64 ~ Flandre Scarlet> Is it possible to call Nim code from C?
13:38:15PMunchYes
13:38:33FromDiscord<System64 ~ Flandre Scarlet> And is it unsafe to do this?
13:38:43PMunchDefine unsafe
13:39:11PMunchIs someone going to stab you with a knife if you do it, probably not. Could you mess something up and crash your program, definitely
13:39:27FromDiscord<System64 ~ Flandre Scarlet> For example if GC is enabled↔Is it possible to have memory problems? such as dangling pointers, memory leaks, etc
13:39:34PMunchIs there a way of doing it that doesn't involve crashing your program, also yes
13:39:46PMunchProblems are always possible
13:40:07PMunchBut if you call NimMain and use ARC/ORC then you're probably fine
13:40:08FromDiscord<System64 ~ Flandre Scarlet> ah alright, so recommanded to call Nim from Nim I guess?
13:40:41FromDiscord<System64 ~ Flandre Scarlet> Ah alright↔I meant in a library context↔you call Nim library from C
13:40:41PMunchI mean if you have the option I'd always use Nim, but for more than this reason alone
13:40:56PMunchYes that is possible, and can be done safely
13:41:09FromDiscord<System64 ~ Flandre Scarlet> Oh alright, good to know

13:54:39FromDiscord<auxym> ARC/ORC makes it easier to call nim from C (don't need to call NimMain or whatever to init the GC). https://github.com/treeform/genny provides macros to generate a C header file for your nim code.↔↔As for safety, I think the gist of it is that C is inherently unsafe. The fact that you call Nim code doesn't really change anything (one way or another).
13:56:28FromDiscord<Yardanico> In reply to @auxym "ARC/ORC makes it easier": `setupForeignThreadGC` is the function needed to setup refc for "foreign threads" and it's not needed for arc/orc, yes
13:56:34FromDiscord<Yardanico> that said, NimMain isn't just limited to GC
13:56:51FromDiscord<Yardanico> if your program or any of libs you import use global variables or global code, you must call NimMain so that this code gets executed

18:18:32FromDiscord<Elegantbeef> If you're wanting help no clue, i never use `=>`
18:20:20FromDiscord<Nerve> Maybe, but mainly this is just a proof of concept that if we take `sequtils` at its namesake and presume `foldl` and `scanl` expect `seq` or `openarray` instead of all possible iterators, it's possible to make very simple `foldl` and `scanl` procs that also give you detailed compiler error checking.
18:20:51FromDiscord<Elegantbeef> With `iterable` it's not impossible for sequtils to do the same
18:20:56FromDiscord<Elegantbeef> you just need to do like `mySeq.items`
