01:45:22FromDiscord<Girvo> And agreed re. closure iterators being a bad fit on embedded. Caused me some pain. I just stopped fighting the language and systems and accepted threaded life 😭

02:37:18FromDiscord<Girvo> Ah wait I see what you're doing
02:38:34FromDiscord<Girvo> Does adding the `: seq[ASTNode]` to the definition's signature help? I guess not?
02:41:59FromDiscord<huantian> I feel like that's the issue?
02:43:02FromDiscord<Tuatarian> Ok I see the issue
02:43:06FromDiscord<Tuatarian> I'm printing void right
02:43:13FromDiscord<Tuatarian> Wait no
02:43:31FromDiscord<Tuatarian> Ok parseExpr shouldn't be returning anything
02:43:39FromDiscord<Tuatarian> That's the problem
02:43:49FromDiscord<huantian> a function that doesn't return anything? what's the point then lmao
02:44:12FromDiscord<Tuatarian> It used to return
02:44:26FromDiscord<huantian> oh yeah it has a var arg
02:44:30FromDiscord<huantian> that makes more sense
02:44:44FromDiscord<Tuatarian> Yeah that's a very silly mistake lmao
02:44:49FromDiscord<Tuatarian> Thanks
02:44:59FromDiscord<huantian> I wonder why that twas the error you got though, I can't seem to reproduce it
02:47:20FromDiscord<Tuatarian> Yeah it was a very odd error
03:11:16FromDiscord<ringabout> Debugging macros makes me sick. Hacks after hacks. Hard to change the compiler without break macros.

07:24:28FromDiscord<vindaar> @flywind\: well, while I can't speak for everyone, I'm more than happy to see macros break, if that means the hacks "we" use are then unnecessary and can be replaced by some cleaner version. Especially if it's about a library I'm somewhat involved with, just ping me and I'll try to help

07:29:32FromDiscord<Elegantbeef> That's a bug
07:29:51FromDiscord<ringabout> Yeah, and somebody's code
07:29:55FromDiscord<Elegantbeef> With modern Nim thanks to the PRs i added `static openarray[int]` is the correct method
07:30:50FromDiscord<ringabout> sent a code paste, see https://play.nim-lang.org/#ix=4e9Q

07:31:32FromDiscord<ringabout> (edit) "I'm going to make this work instead of the former ... one." added "array"
07:34:35FromDiscord<Elegantbeef> Yea this is the right path imo, but not overly great for backwards compatibillity
07:34:56FromDiscord<Elegantbeef> Only correct code should work, if incorrect code works and you rely on it, it's not great

10:10:32FromDiscord<Tanguy> Do we have any idea what's the nim community size? Trying to compare to rust etc
10:13:26madpropswell the reddit has 5.7k subscribers
10:13:49madpropsthe rust one has 204k
10:17:13FromDiscord<Tanguy> Thanks, also found this https://api.github.com/search/repositories?q=language:Nim↔So between reddit & github, it seems it's about ~40 times smaller than rust
10:17:40FromDiscord<Tanguy> And ~150 times smaller than g
10:17:41FromDiscord<Tanguy> (edit) "g" => "go"
10:19:40FromDiscord<dom96> Community size is tough to gauge, language use/popularity might be better but also tough to gauge
10:19:52FromDiscord<dom96> I personally like Wikipedia pageview stats https://pageviews.wmcloud.org/?project=en.wikipedia.org&platform=all-access&agent=user&redirects=0&start=2015-07&end=2022-09&pages=Nim_(programming_language)|Rust_(programming_language)
10:21:31FromDiscord<dom96> Repo counts are definitely interesting too. Zig has half as many as Nim
10:21:45FromDiscord<dom96> (with the amount of time Zig has been around I'd say it's doing better)
10:43:25NimEventerNew thread by drkameleon: Change ref object variant in-place - drawbacks?, see https://forum.nim-lang.org/t/9552
10:53:20FromDiscord<Ekopalypse> Is this something that is still valid and I need to take care of?↔https://nim-lang.org/docs/nimc.html#dll-generation↔Because I have created two dlls for a cpp app and both are loaded, running and allocating memory all the time but I haven't seen any signs yet that GC is not doing its job.

12:27:18*arkurious joined #nim
12:38:06FromDiscord<haxscramper> In reply to @Tanguy "Do we have any": search `language:nim` on github
12:38:49FromDiscord<ringabout> And https://plausible.io/nim-lang.org
12:39:00FromDiscord<haxscramper> https://api.github.com/search/repositories?q=language:nim
12:39:09FromDiscord<haxscramper> this shows direct count,
12:39:42FromDiscord<haxscramper> for reference, at [8/25/21 2:37 PM] it as at 6.5k
12:40:07FromDiscord<Tanguy> Also found it, see my last message 🙂 8k repos for nim, 380k for rust & 1.123m for go
12:40:28*derpydoo joined #nim
12:41:35FromDiscord<haxscramper> proper metric of the community size would probably involve something like
12:41:47FromDiscord<haxscramper> number if unique users that contributed to all the projects marked in this language
12:42:16FromDiscord<haxscramper> depends on how exactly you define "community"
12:42:25FromDiscord<haxscramper> In reply to @haxscramper "https://api.github.com/search/repositories?q=langua": that uses "community == contributors"
12:42:38FromDiscord<haxscramper> In reply to @flywind "And https://plausible.io/nim-lang.org": "communty == onlookers"
12:42:47FromDiscord<haxscramper> In reply to @dom96 "I personally like Wikipedia": "== unlookers"
12:43:15FromDiscord<haxscramper> In reply to @madprops "well the reddit has": this one I'm not sure, but I guess it is mostly onlookers, sometimes contributors
12:43:27FromDiscord<haxscramper> It's well known that most people only read, don't post and don't comment
12:44:37FromDiscord<haxscramper> In reply to @flywind "And https://plausible.io/nim-lang.org": there is a large number of people who just saw a link on HN/reddit and decided to investigate https://media.discordapp.net/attachments/371759389889003532/1034809777072648192/unknown.png

13:25:37PMunchHmm, anyone know how to merge a date and a time in Nim?
13:26:15PMunchI have a bunch of files in folders. The name of each folder is a day in the format yyyy-MM-dd, and each line in the file contains a hh:mm timestamp along with a value
13:26:46PMunchI have parsed the date as a DateTime object with the times module, and now I want to set the time in it
13:31:36FromDiscord<Saint> Is it possible to change a variable type?
13:31:50FromDiscord<Saint> Like if I want to reassign something to a variable and change that variables type
13:31:52PMunchWhat do you mean?
13:32:04FromDiscord<Saint> like var a used to be a list but now I want to assign a map to a
13:32:07PMunchAh, no that's not possible
13:32:08FromDiscord<Saint> If that makes sense
13:32:11FromDiscord<Saint> Oh okay thanks
13:32:16PMunchWell, you can shadow a variable
13:32:37FromDiscord<Saint> What's that?
13:32:37PMunchSo if you have a global variable a which is a sequence you can have a local variable a which is a map
13:33:38FromDiscord<Bung> cast or use a convertor
13:34:27PMunchHuh?
13:34:56FromDiscord<Saint> In reply to @PMunch "So if you have": Oh okay
13:35:53FromDiscord<Bung> why talk about variable scope now..
13:36:06PMunchOf course you could also have an object variant @Saint
13:36:23PMunch@Bung, because they asked if they could change the type of a variable
13:38:20FromDiscord<Bung> hmm, change type doesn't sound same as refer to other scope variable..
13:39:11FromDiscord<Rika> It’s a way to simulate it
13:39:15PMunchYes of course, I was just trying to explain all the intricacies
13:39:22FromDiscord<Saint> Another question, I don't get a line number error for an exception
13:39:32FromDiscord<Saint> Uncaught exceptions, is there a way to get that in my stack trace

13:45:26FromDiscord<Saint> Won't tell me where it actually fails in my program, but in some library
13:53:18PMunchAh, that can sometimes happen when things are expanded on compile-time unfortunately
13:53:50PMunchBut the error seems to be that you try to do `for x in y` where y is a JsonNode but not a Json array
13:59:18FromDiscord<Saint> In this case yeah I know where the error is coming from, just wondering what would happen in a more complex case where I don't really know where the error is coming from
13:59:43FromDiscord<Saint> Is there an easy way to filter a table based on which keys I want? Like python's dict comprehension, or pandas?
14:06:26PMunchNot a oneliner afaik
14:15:59PMunchWell, I guess you could do something like this: `myTable = myTable.pairs.toSeq.filterIt(it[0] in 'a'..'z').toTable`

16:38:00FromDiscord<albassort> You don't need to mess with memory
16:40:18FromDiscord<Rika> Single core microcontrollers can still be threaded
16:40:44FromDiscord<Rika> Just not parallelised so it’s closer to a mix of async and threads
16:43:08*derpydoo quit (Ping timeout: 272 seconds)
16:45:21*derpydoo joined #nim
16:50:46FromDiscord<auxym> yeah, all RTOSs for MCUs come with a "thread" or "task" mechanism, which is either pre-emptive (uses interrupts to stop your code at an arbitrary point, saves the stack for a later resume, etc) or non-preemptive, which is like async/coroutines (you decide when to "yield", at which point the os/scheduler runs another coroutine until it yields, etc)
16:52:15FromDiscord<auxym> I still have some idea for a very lightweight coop scheduler based on actors/message passing. The new Tasks in the stdlib would be a good fit for that I think. Need to play around witht that idea sometime.
16:52:21FromDiscord<Rika> “Non preemptive” is called cooperative just an FYI ;P
16:53:00FromDiscord<auxym> is also called cooperative 😉 non-preemptive is definitely a term I've seen in many places
16:53:59FromDiscord<Rika> Really, huh
16:54:03FromDiscord<Rika> Good to know lol
16:57:32FromDiscord<albassort> In reply to @Rika "Single core microcontrollers can": But isn't the only reason why threads are cool Is operating in parallel, wouldn't coroutines just be far superior if not parallel
16:58:14FromDiscord<albassort> Why are dreads threads threads
