00:02:35FromDiscord<leorize> what `--gc` are you using?
00:06:46ricemanI've tried boehm, arc, and the standard Nim GC. In the past, I had this issue on a project that needed to rapidly send post requests via httpclient and boehm solved the crashes, but no luck this time w that
00:09:04ricemanI'm trying to walk directories recursively to get a list of the files inside, about 4,000, and then upload them to an AWS bucket. I've tried running spawn(file) directly, as well as writing the list to a file and doing "for line spawn()", but both eventually crash.
00:10:34ricemansleep(100) or so seems to help between thread spawns, but it still SIGSEGVs eventually, no matter how slow I make it go.
00:11:04FromDiscord<leorize> are your threads accessing any global resources?
00:12:34ricemanI don't believe so, but I'm a hobbyist programmer up until recently. I'm passing each line to the async function via parameter. That's the only thing being used that originates globally. Spawning clients inside the async proc too to be safe.
00:14:28ricemanThanks for the help, by the way! I appreciate it
00:15:50FromDiscord<leorize> wait wait wait
00:16:03FromDiscord<leorize> you're using asyncdispatch and threadpool?
00:16:43FromDiscord<leorize> mixing both async and thread is a very dangerous recipe in nim \:P
00:18:04FromDiscord<leorize> if you have an async procedure, then you can just collect all `Future` from them into a seq then use `asyncdispatch.all()` to wait for all of them to be done
00:18:38FromDiscord<leorize> if you want to both do this and multi-threaded, then the creation of these async procedure should be done within their respective threads
00:23:15ricemanThat's great to know, thank you. I'll do some googling and see what I can find out about asyncdispatch.all() usage. Really appreciate it.
00:42:24FromDiscord<leorize> sorry, it's in asyncfutures
00:42:54FromDiscord<leorize> can you explain a bit on how your threadpool + async workflow works?
00:49:55ricemanGotcha! And sure! I'm using async because it's tied to the only functional s3 library I could find. My script is so short it might be able to be easily pasted here.
00:51:34riceman```proc up(upload:string) =; var client:S3Client; var creds:(string,string); discard client.put_object("BUCKET", upload, readFile(upload)); for file in walkDirRec("./data"): discard spawn up(file)```
00:52:03ricemanThat's essentially my entire script right there, minus credentials and bucket name.
00:54:27FromDiscord<leorize> which s3 library are you using?
00:57:17ricemanI'm using https://github.com/ThomasTJdev/nim_awsS3. It's a bit broken, but the other two I tried were seemingly nonfunctional, even with modifications
01:00:48FromDiscord<leorize> I think the s3PutObject api would work better
01:01:23FromDiscord<leorize> since it doesn't rely on you having to read the file before passing it on
01:02:54FromDiscord<leorize> so to use it you gotta do this\:
01:07:22FromDiscord<leorize> sent a code paste, see https://play.nim-lang.org/#ix=3s5f
01:07:50FromDiscord<leorize> ^ hopefully that would work for your usage, afaict from the library you sent
01:09:50FromDiscord<leorize> might need a few fixes here and there since I've never worked with AWS before
01:15:02ricemanLet me give that a shot and see! You're amazing, thank you.
01:22:10FromDiscord<leorize> you might want to use this API\: https://github.com/ThomasTJdev/nim_awsS3#s3putobjectis2xx
01:22:12fn<R2D299> itHub: 7"Amazon Simple Storage Service (AWS S3) basic API support"
01:22:32FromDiscord<leorize> then in the case where upload fails you can echo the failed file or smt
01:27:26ricemanTried that to begin with, but something about it wasn't working. Let me take another look at it.
01:28:08ricemanA big issue is the library controls the http client, which seems to invoke some weird design quirks that I have a hard time working around.
01:30:14ricemanAh, right. the 2xx one was giving me 400 errors with the proper creds, so it seems to be broken or I'm unknowingly incorrectly using it in some major way
01:31:11FromDiscord<leorize> you can try echo-ing out the response \:p
01:34:40ricemanIt's echoing me the response, but it seems to be speaking in terms the API isn't expecting or wanting
01:35:07FromDiscord<leorize> then I can't help you with that, sorry \:/
01:36:11ricemanUnfortunately, it looks like AWS uses Java exclusively for a special bulk-upload feature of the api... ah man.
01:36:44ricemanMight have to hop to that to bypass the individual file method. Either way, thank you a ton for your help. I learned a lot about async usage today!
01:38:47FromDiscord<leorize> you're welcome \:)

03:57:17FromDiscord<aleclarson> is there a obviously fastest way to convert int to string?
03:57:25FromDiscord<aleclarson> (edit) "a" => "an"
03:57:43FromDiscord<aleclarson> or does `repr` work fine for performance-intensive scenarios?
03:58:45FromDiscord<Rika> Repr? Why not $
03:59:19FromDiscord<Rika> I’m pretty sure it’s fast enough, stringifying an integer isn’t as difficult as a float
04:00:36FromDiscord<aleclarson> great thx
04:02:20FromDiscord<Rika> If you’re looking for a bottleneck it’s best to use a profiler

09:02:18FromDiscord<planetis> (bc getCurrentExpeption just returns a new reference and doesnt move the exception)
09:02:48FromDiscord<planetis> there is also https://nim-lang.github.io/Nim/system.html#globalRaiseHook and localRaiseHook
09:02:56FromDiscord<planetis> not sure how they work
09:08:14FromDiscord<no name fits> How do you guys handle when requirements for GUI changes all the time? I'm seriously so sick of doing UI already, and when I have to keep "fixing" it, it feels like I'm getting nothing done
09:08:41FromDiscord<ElegantBeef> I dont do UI much but dont follow what you mean 😄
09:09:48FromDiscord<Rika> Basically when you need to change the layout again/?
09:10:07FromDiscord<Rika> I think that's one reason people use Immediate Mode gui
09:10:15FromDiscord<Rika> Painless to change the layout
09:10:16FromDiscord<no name fits> sent a long message, see http://ix.io/3s6D
09:10:56FromDiscord<no name fits> At which point the "forgot password" flow becomes obsolete because it's tied to your vendor
09:12:37FromDiscord<no name fits> I think I'm trying to ask if there's a way to do UI so these changes are less of a hassle
09:13:42FromDiscord<no name fits> And sorry if I seem irritated. I thought I had a chance to knock down some tasks today but I got put on "clean the coffee machine" duty
09:14:36*pro quit (Quit: WeeChat 3.2)
09:17:42FromDiscord<Rika> as ive said probably best to look into immediate mode ui

09:27:38FromDiscord<no name fits> And I just splashed myself with water 🙂

11:45:46FromDiscord<Zoom> Is it considered long? It's less than 500 lines
11:46:00FromDiscord<Rika> well i think it can be shorter
11:46:29FromDiscord<Rika> thats fine for now i guess
11:46:31FromDiscord<Rika> minor issue
11:46:45FromDiscord<Zoom> Yeah, splitting CLI handling is the first candidate.
11:48:25FromDiscord<Zoom> Isn't my description clear enough? I'm more interested in hearing your thoughts on the whole idea first than on the particular implementation↵(@Rika)
11:48:34FromDiscord<Rika> not for me it isnt

11:48:57FromDiscord<Rika> im not someone who can understand things by description
11:49:14FromDiscord<Rika> but i have a feeling that the length field is redundant
11:49:27FromDiscord<Rika> not that i can actually tell because yeah
11:58:45FromDiscord<Rika> In reply to @Zoom "Ok. I'll push soon": if you werent sure it was a good idea, you should have made a branch first and made the changes there
11:58:53FromDiscord<Rika> then you merge the branches when you're sure
11:59:07FromDiscord<Rika> otherwise you can just delete it then carry on with the older code

14:33:14FromDiscord<Clonkk> 1. It's not a solution, it's a temporary workaround. 2) Many services that are based on emails will ban throw out email. 3) Throw-out emails are usually not secure and leave your accont exposed to being stolen.
14:33:22FromDiscord<Clonkk> The only good solution is the development of privacy friendly alternative
14:34:47FromDiscord<Clonkk> And yes, that will usually require compromise in functionnality and ergonomics because those costs money
14:34:58FromDiscord<gerwy> but no one wants to use alternative, thats the problem
14:36:00FromDiscord<hugogranstrom> I'm I no one? ;)
14:38:11FromDiscord<hugogranstrom> But true, most people don't care about their privacy sadly. Or even worse, don't realize to what extent they give up their privacy
14:39:47FromDiscord<Rika> not really no one, "none of my friends"
14:39:55FromDiscord<Rika> none of the laymen care enough
14:40:01FromDiscord<Rika> its a negative feedback loop
14:40:01FromDiscord<hugogranstrom> If more people did understand that, I'm sure more people would look for "alternatives"
14:40:02FromDiscord<vindaar> 💯
14:40:32FromDiscord<Rika> In reply to @hugogranstrom "But true, most people": even if they knew the losses in privacy, there's still convenience
14:40:33fn<Prestige99> You have friends?

14:42:06FromDiscord<Zoom> Rika, have you seen my answers regarding my ShuffleArray? Discord bridge lagged
14:42:40FromDiscord<Rika> i dont think so
14:42:52FromDiscord<Rika> i only see a "yep
14:42:53FromDiscord<Rika> "
14:43:32FromDiscord<Zoom> So, ShuffleArray.L is capacity and `len` field is, well, length. `idx` are index association array which is the point of the whole thing
14:46:18FromDiscord<Zoom> Is this type a good idea and what's wrong with the init proc, as it gives me a `can't prove` warning
14:46:41fn<Prestige99> @Rika didn't mean to offend, was just a self-deprecating joke
14:47:05FromDiscord<Rika> okay
14:48:06FromDiscord<Rika> the init proc needs to use the init syntax `result = ShuffleArray[L, T](len: 0)` replaces the result.len line
14:48:09FromDiscord<Rika> i believe
14:48:29FromDiscord<Rika> whats the index association array for? whats the benefit?

14:54:56FromDiscord<vindaar> I do, with varying success. Many people say they understand what I'm saying, but then immediately go on about convenience and "ahh, they don't care about me specifically / I have nothing to hide".↵But then I just force them by not using whatsapp anymore 😛↵(<@709044657232936960_fn=5b=49=52=43=5d>)
14:56:11FromDiscord<deech> What does the `=trace` hook do?
14:59:35*Vladar quit (Remote host closed the connection)
15:01:48FromDiscord<Zoom> The main use case of the type is frequent reordering so this trades index indirection for less moves in memory↵(@Rika)
15:03:49FromDiscord<Rika> so instead of an N\count byte shift it's a 4count byte shift?
15:04:01FromDiscord<gerwy> well i care about privacy but its pretty hard to hold it in modern world↵its not 90s, everything is for some reason digitalized and we don't have our own stuff anymore, everything is in cloud and shared to us which is sad
15:04:40FromDiscord<leorize> it doesn't do anything anymore, but originally it was made for the gc to traverse custom types for reference scanning by `refc`. ARC/ORC obsoleted this though↵(@deech)
15:06:14FromDiscord<dom96> In reply to @Zoom "You know the answers,": I know some of the answers, but always curious about why specific people are opting for it
15:07:10FromDiscord<haxscramper> I want to write my own client for it, and with discord it is not possible
15:07:49FromDiscord<haxscramper> But discord has better search for chat

15:12:31FromDiscord<dom96> In reply to @haxscramper "I want to write": I've gone down this path with IRC and learned that I should have created Slack/Discord all along 😉
15:12:36FromDiscord<Zoom> If you'd like to know, Matrix is a protocol, Discord is an implementation of a protocol which actively discourage third-party clients. That's just one of the reasons but I think it's enough to not use it.

15:13:36FromDiscord<leorize> matrix is really just discord but open and decentralized
15:14:10FromDiscord<leorize> it's working well, so why not use it?
15:14:16FromDiscord<dom96> Of course, that's fair. Personally I don't really mind, I can easily switch to Matrix (or back to IRC) if Discord annoys me
15:15:11FromDiscord<dom96> I don't have any real reason to use it
15:15:14FromDiscord<Zoom> May be we should continue in #offtopic

15:22:10FromDiscord<Zoom> I had basically the same question a few days ago. What would be the proper place in the manual to put this in?
15:29:38FromDiscord<haxscramper> Generics, generic parameters
15:29:41FromDiscord<haxscramper> Probably not `static:` block
15:29:41FromDiscord<haxscramper> Actually generic example is really dense

16:07:37FromDiscord<haxscramper> Doesn't work how? And you need to add () if you want to assign yo var

16:21:17FromDiscord<vindaar> it was deprecated an hour ago or so
16:21:22FromDiscord<haxscramper> Ah
16:21:25FromDiscord<Rika> lmao
16:21:26FromDiscord<haxscramper> Quick reaction
16:21:49FromDiscord<vindaar> the new package is by the person who added it to the stdlib if I'm not mistaken
16:21:53FromDiscord<haxscramper> And a day ago I wanted to write inflammatory RFC about keeping modules small
16:22:09FromDiscord<Rika> lol
16:22:38FromDiscord<haxscramper> From our discussion on genast
16:23:22FromDiscord<haxscramper> I meant not keeping modules small and instead adding things to existing ones
16:23:54FromDiscord<leorize> we should encourage more packages instead of keep piling onto the stdlib
16:24:08FromDiscord<haxscramper> But anyway, how this got into stdlib (sums) in the first place is still beyond me
16:24:27FromDiscord<leorize> it's hard right now because, well, nimble
16:25:10FromDiscord<haxscramper> Do you think new RFC would fix that?
16:25:11FromDiscord<leorize> the basics, then yea
16:25:32FromDiscord<leorize> it's not fixing the "using a package is harder than stdlib", but that is not too important right now

18:28:10FromDiscord<gerwy> guys pls halp
18:29:06fn<Prestige99> read a file by its path?
18:29:31FromDiscord<gerwy> yeah, how to get file by its path, not by the filename, because putting path into `open` doesn't work
18:31:10FromDiscord<timotheecour> define filename; it can be used with different meanings. you have `readFile(path)` if that's what you want.
18:33:34FromDiscord<gerwy> nope, doesn't work
18:33:52FromDiscord<gerwy> it takes filename too
18:34:11FromDiscord<timotheecour> then define your meaning of path
18:35:17FromDiscord<gerwy> not relative path to file↵what i mean by that is i open script in one place and i want it to open file in another place, not relative to the script
18:35:36FromDiscord<gerwy> for example i open script at ~/ but the files i need are in ~/Youtube Fetcher/
18:35:36*fputs joined #nim
18:35:38fn<Prestige99> So you have an absolute path to the file?
18:35:43FromDiscord<gerwy> yep
18:35:44FromDiscord<gerwy> how
18:36:20fn<Prestige99> idk if it expands ~
18:36:23fn<Prestige99> if you're using that
18:37:02FromDiscord<gerwy> yeah well hmm it should but i will try absolute path from root
18:38:05FromDiscord<gerwy> hmm doesn't output error so i guess it works :3↵But i would treat it as a bug or lack of functionality, it should expand ~ i think
18:38:09FromDiscord<RattleyCooper> You can use `os.getHomeDir()` to get home directory without knowing username, etc
18:38:36FromDiscord<RattleyCooper> and you can make your own expanding function
18:38:42FromDiscord<gerwy> okaay i will add that if someone else would like to use this program, but its not likely
18:38:58FromDiscord<timotheecour> see expandTilde
18:39:07FromDiscord<RattleyCooper> or do that XD

19:13:18FromDiscord<konsumlamm> In reply to @ynfle (ynfle) "I don't think I": well you covered all cases, but the macro doesn't know that, it doesn't check for exhaustiveness, so you need to add a dummy `else` case
19:13:40FromDiscord<konsumlamm> or change the last case to an else
19:13:56FromDiscord<gerwy> In reply to @Kermithos "nice, any ratelimit problems?": what do you mean by ratelimit ?

19:14:37FromDiscord<Kermithos> In reply to @Life Sucks "what do you mean": the first time I told you about the RSS endpoint you said that you may get ratelimited by youtube
19:16:01FromDiscord<gerwy> hmm i was talking about FreeTube, because after some amount of subscribers you have on it, it switches from i think Youtube's API (or Local API idk, something like this) to RSS Feed, so you won't get banned or slowed down
19:16:11FromDiscord<Kermithos> ah ok
19:16:44FromDiscord<gerwy> rss feed is actually pretty fast, i slow down my app a little so that it doesn't quit suddenly and also gives me time to react for new videos showed
19:17:08FromDiscord<gerwy> but well, for now no new vids are here :3 so need to wait for them to see if it actually works
19:17:12FromDiscord<Kermithos> is the code already on github?

19:19:12FromDiscord<gerwy> noope, its a little messy, i didn't planned on open sourcing it↵i can share it with you if you have any improvements ↵its almost less than 100LoC
19:19:28FromDiscord<haxscramper> `else` clause is mandatory
19:19:28FromDiscord<haxscramper> There is no exhaustiveness cheking in `fusion/matching`
19:19:29FromDiscord<haxscramper> But I think it should be added in v2 for simple cases
19:19:29FromDiscord<haxscramper> Though it is not really useful
19:19:29FromDiscord<haxscramper> Except for tuples of enum and case objects
19:19:32FromDiscord<haxscramper> IIRC there is no implementation documentation, but you can look into compiler
19:19:32FromDiscord<haxscramper> `compiler/vm`
19:19:32FromDiscord<ynfle (ynfle)> @haxscramper\:matrix.org how hard do you think it is to implement
19:19:33FromDiscord<haxscramper> It is a register-based VM with opcodes
19:20:25FromDiscord<Kermithos> In reply to @Life Sucks "noope, its a little": sure, if you want you can send me the code via PM
19:20:43FromDiscord<haxscramper> Depends on the subset of features you want to support
19:20:48FromDiscord<haxscramper> and `case` in matching is `untyped`
19:20:48FromDiscord<haxscramper> In order to implement full coverage checking you need to have a type information
19:20:51FromDiscord<haxscramper> And it is extremely annoying to work with
19:21:03FromDiscord<haxscramper> So yes, it is doable, I even know how, but not sure if the effort worth it
19:21:32FromDiscord<haxscramper> But it would turn into multistage macro
19:22:27FromDiscord<@bracketmaster-5a708063d73408ce4> some crude tests seem to indicate nimVM is about 1000 times slower than python

19:23:16FromDiscord<leorize> it is slower than python vm, confirmed by Araq
19:23:17FromDiscord<ynfle (ynfle)> Not having to as an else for tuples and objects
19:23:28FromDiscord<haxscramper> `> about 1000 times `?
19:23:42FromDiscord<@bracketmaster-5a708063d73408ce4> I know, I was wondering about how much slower in practice
19:23:51FromDiscord<@bracketmaster-5a708063d73408ce4> fac BigInt is a solid test
19:24:05FromDiscord<leorize> not sure what's the metric, but it's not fast fast, for sure
19:24:10FromDiscord<@bracketmaster-5a708063d73408ce4> BigInt is data structure as well as arithmetic intense
19:24:36FromDiscord<@bracketmaster-5a708063d73408ce4> BigInt requires traversing and appending a Seq as well as lots of multiplies and adds
19:24:38FromDiscord<haxscramper> In reality it means "not having `else` for flat tuples with enum values and objects that dont' have their field matched". Everything else is hard to implement
19:24:38FromDiscord<leorize> isn't most python bigints shell out to C?
19:24:58FromDiscord<@bracketmaster-5a708063d73408ce4> BigInt in Nim -c -r is about as fast as Python
19:25:23FromDiscord<haxscramper> That means python shells out to C
19:25:25FromDiscord<@bracketmaster-5a708063d73408ce4> yes - I know
19:25:28FromDiscord<ynfle (ynfle)> What does "objects that don't have their field matched mean?
19:25:51FromDiscord<gerwy> In reply to @Kermithos "sure, if you want": if you want it, because im pretty done with the code and if it works, its finished for me, i kinda made it for myself so there isn't any error checking and the absolute path is also made for my disk so if you want to test it out you need to change it
19:26:03FromDiscord<@bracketmaster-5a708063d73408ce4> Actually, BigInt in compiled Nim is 10x slower than Python - but that's the fault of BigInt implementation
19:26:18FromDiscord<@bracketmaster-5a708063d73408ce4> If we factor that in, we could say nimVM is 100x slower than Python?
19:26:22FromDiscord<haxscramper> sent a code paste, see https://play.nim-lang.org/#ix=3s9Q
19:26:28FromDiscord<@bracketmaster-5a708063d73408ce4> like I said - very crude

19:26:42FromDiscord<@bracketmaster-5a708063d73408ce4> but nimVM is clearly much slower than Python
19:26:53FromDiscord<@bracketmaster-5a708063d73408ce4> I just didn't expect it to be that much slower
19:26:56FromDiscord<haxscramper> checking for `strVal` - impossible by definition
19:27:27FromDiscord<leorize> if you want a VM bench it should be fully contained in the VM
19:27:49FromDiscord<@bracketmaster-5a708063d73408ce4> fac(100) is fully contained in the VM
19:28:01FromDiscord<leorize> at the moment we don't have compiler plugins yet to shell some vm code to native for speed up, nor do we have jit
19:28:40FromDiscord<@bracketmaster-5a708063d73408ce4> yes - I realize that
19:28:57FromDiscord<haxscramper> No, it is spread between VM and compiled part. For example internally VM uses `PNode` to operate on sequences, so most likely sequence addition part runtime comes from VM
19:29:05FromDiscord<haxscramper> moving data to and from
19:29:19FromDiscord<haxscramper> IIRC it uses `PNode` to represent runtime values
19:29:28FromDiscord<leorize> that's just impl detail
19:29:52FromDiscord<@bracketmaster-5a708063d73408ce4> the reason I bring this up is because I'm implementing a digital logic(like Verilog or VHDL) language in Nim
19:30:04FromDiscord<@bracketmaster-5a708063d73408ce4> Digital logic languages have two phases, elaboration and simulation
19:30:11FromDiscord<ynfle (ynfle)> So what does matched mean in this case?
19:30:13FromDiscord<@bracketmaster-5a708063d73408ce4> I'm trying to move elaboration to compile time
19:30:17FromDiscord<leorize> what we are focusing on is that all non-primitive operations are in the vm itself and not optimized by compiling to native
19:30:32FromDiscord<timotheecour> https://github.com/timotheecour/Nim/issues/598 would solve that
19:30:58FromDiscord<@bracketmaster-5a708063d73408ce4> but I don't know if elaboration at compile time would be too slow - I guess there's only one way to find out
19:31:22FromDiscord<timotheecour> (edit) "that" => "that. There's indeed no upper bound on cost of VM relative to native code (python comparison is irrelevant because it can use C), depending on use case."
19:31:34FromDiscord<haxscramper> [ynfle (ynfle)](https://matrix.to/#/@ynfle-5f16f3e4d73408ce4fea241f:gitter.im)\: matched means ... matched? We are doing pattern matching, so matched means "object triggers against this branch, and it is executed"
19:31:43FromDiscord<leorize> if you're mainly generating AST then it should not be too slow
19:31:47FromDiscord<timotheecour> (edit) "that." => "that, allowing VM for select user defined code to be as fast as native code."
19:31:56FromDiscord<haxscramper> sent a code paste, see https://play.nim-lang.org/#ix=3s9T
19:31:57FromDiscord<@bracketmaster-5a708063d73408ce4> yes - mainly AST
19:33:19FromDiscord<@bracketmaster-5a708063d73408ce4> but a user of the DSL could decide they want to do some expensive computation to determine to parameterize their logic↵↵I guess the answer is, just don't do that
19:34:10FromDiscord<haxscramper> Isn't this stuff terribly expensive?
19:34:47FromDiscord<@bracketmaster-5a708063d73408ce4> elaboration is just AST traversal
19:34:53FromDiscord<@bracketmaster-5a708063d73408ce4> simulation is the expensive part
19:35:34FromDiscord<@bracketmaster-5a708063d73408ce4> now if the person has a very complex design such as a 2000 core GPU, elaboration can get pretty expensive
19:36:28FromDiscord<haxscramper> hmm, maybe I've just messed up terms. I thought elaboration included layout and all that kind of styff
19:36:50FromDiscord<@bracketmaster-5a708063d73408ce4> no, thats PNR - or place and route
19:37:40FromDiscord<@bracketmaster-5a708063d73408ce4> elaboration consumes some DSL and spits out a digital circuit
19:37:43FromDiscord<@bracketmaster-5a708063d73408ce4> that is represented as a graph
19:38:24FromDiscord<haxscramper> netlist? Btw, there is a third option - you can use nimscript and pass some implementation procs to it, that do all heavy lifting
19:39:03FromDiscord<haxscramper> But that is only viable if your DSL is completely detached from other nim code
19:39:04FromDiscord<haxscramper> Just purely DSL
19:39:04FromDiscord<haxscramper> Just pure DSL
19:39:05FromDiscord<@bracketmaster-5a708063d73408ce4> circuit == netlist in most contexts I think
19:39:37FromDiscord<@bracketmaster-5a708063d73408ce4> the netlist elaboration spits out is usually far less granular than the synthesis netlist however
19:40:01FromDiscord<@bracketmaster-5a708063d73408ce4> implementation procs?
19:40:09FromDiscord<@bracketmaster-5a708063d73408ce4> tell me more?
19:41:33FromDiscord<haxscramper> You can embed nimscript in your program - https://github.com/haxscramper/hack/blob/master/testing/nim/compilerapi/test5.nim#L112↵Or you can use `compiler/parser` that would accept nim code
19:41:52FromDiscord<haxscramper> Basically if everything you care about is a macro, you can implement a program
19:41:59FromDiscord<haxscramper> That would act like a macro
19:42:08FromDiscord<haxscramper> Takes nim code, generates `<something>`
19:42:53FromDiscord<haxscramper> But that is more of an extreme option, and I haven't done this for anything yet
19:43:31FromDiscord<haxscramper> I'm just saying it is possible, and not that hard (AST for `compiler/parse` is exactly as NimNode, except it is called PNode)
19:43:55FromDiscord<haxscramper> and some other details

19:44:59FromDiscord<@bracketmaster-5a708063d73408ce4> interesting
19:51:00FromDiscord<haxscramper> If you are writing language (almost) from scratch you can go with compiler parser
19:51:23FromDiscord<haxscramper> Basically just save time on parser
19:52:13FromDiscord<@bracketmaster-5a708063d73408ce4> what do you mean by this?
19:53:50FromDiscord<haxscramper> By "implementing digital logic language" you mean you are writing one from scratch, correct?
19:54:03FromDiscord<haxscramper> And you want to reuse nim macros to define language syntax
19:54:41FromDiscord<@bracketmaster-5a708063d73408ce4> yes
19:54:45FromDiscord<@bracketmaster-5a708063d73408ce4> here is a snippet\:
19:54:50FromDiscord<@bracketmaster-5a708063d73408ce4> sent a long message, see http://ix.io/3s9W
19:54:55FromDiscord<haxscramper> sent a code paste, see https://play.nim-lang.org/#ix=3s9X
19:55:34FromDiscord<Bung> oh, nimscripter why I not notice it earlier , maybe I could use it as theme plugin
19:55:40FromDiscord<haxscramper> I though you just wanted to reuse syntax. But you really want to
19:55:45FromDiscord<haxscramper> use nim type system as well?
19:56:19FromDiscord<haxscramper> Or not? The ` Output c = Signed(1024.Max)` part confuses me
19:56:30FromDiscord<@bracketmaster-5a708063d73408ce4> yes - although I'm open to other options
19:56:47FromDiscord<@bracketmaster-5a708063d73408ce4> What that means is create an 11bit signal
19:57:00FromDiscord<@bracketmaster-5a708063d73408ce4> because we need 11 bits to represent a signed 1024 value
19:57:07FromDiscord<haxscramper (haxscramper)> yes, that message certainly didn't go well through the bridge
19:58:06FromDiscord<haxscramper (haxscramper)> Well, that's an interesting one
19:58:31FromDiscord<@bracketmaster-5a708063d73408ce4> https://spinalhdl.github.io/SpinalDoc-RTD/SpinalHDL/Structuring/components_hierarchy.html#introduction
19:58:35FromDiscord<@bracketmaster-5a708063d73408ce4> that's another one from Scala
19:59:11FromDiscord<haxscramper (haxscramper)> So ideally you want to write this DSL code and make it output netlist, but benefit from nim type checking, correct?
19:59:46FromDiscord<@bracketmaster-5a708063d73408ce4> yes. also, I'd like to support netlist simulation in nim
19:59:58FromDiscord<@bracketmaster-5a708063d73408ce4> although if I export the netlist to verilog, I could simulate in verilator
20:00:40FromDiscord<@bracketmaster-5a708063d73408ce4> In fact, verilator has a c simulator api - its possible to use verilator as a simulation backend from other languages
20:01:09FromDiscord<haxscramper> I think you can do this using compiler API
20:01:10FromDiscord<haxscramper> But no nim macros
20:01:36FromDiscord<@bracketmaster-5a708063d73408ce4> Do you think that's a better idea?
20:01:49FromDiscord<haxscramper> So the idea is - you write your code in separate file as your DSL, then you parse it using `compiler/parser`. Then you convert the code into something nim can semcheck
20:01:59FromDiscord<@bracketmaster-5a708063d73408ce4> Also - want to DM so we don't blow up the Nim chat?

21:16:39FromDiscord<ynfle (ynfle)> it's traced
21:16:55FromDiscord<ynfle (ynfle)> `ptr` & `pointer` is generally for interface with C

21:38:18FromDiscord<talaing> Honestly, it's pretty confusing ._.

21:40:39FromDiscord<ynfle (ynfle)> \basically just array of `char`s with a null terminater
21:40:50FromDiscord<ynfle (ynfle)> Use the high level ones that use `var string`

21:44:45FromDiscord<dom96> @talaing what's your goal?
21:48:25FromDiscord<ynfle (ynfle)> How can I use 2 experimental features? 2 experimental statements?
21:49:32FromDiscord<talaing> I'm writing a program which is extremely performance sensitive, I mean I need to achieve speed as fast as possible. I believe there is faster way to use sockets than importing entire `net` module and that's why I want to use lowest level module possible - `nativesockets`.

22:23:27FromDiscord<KJ> hmmm, one of my cores was pegged at 100%, turns out `nimsuggest` was absolutely devouring cpu usage
22:23:59FromDiscord<talaing> In reply to @dom96 "surely you can give": I need to send ~18 HTTP requests as fast as possible. My current program which uses `net` does it within `0.006s` which may seem like you can't do better than that, but like I said, I believe I can do way better than that with `nativesockets` module.
22:24:31FromDiscord<talaing> They are all POST requests with some json data.
22:24:55FromDiscord<talaing> (edit) "`0.006s`" => "`0.007s`"
22:25:05FromDiscord<talaing> (edit) "`0.007s`" => "`~0.007s`"
22:27:31FromDiscord<dom96> do all HTTP requests go to the same hostname?
22:27:49FromDiscord<talaing> That's right
22:28:02FromDiscord<dom96> cool, so you can eliminate `getAddrInfo`
22:28:18FromDiscord<dom96> just sock.connect("ip")
22:28:39FromDiscord<talaing> Oh, good to know!
22:29:34FromDiscord<dom96> although if you're doing POSIX sockets then you'll still need to construct this addr info struct
22:30:27FromDiscord<dom96> https://en.wikipedia.org/wiki/Berkeley_sockets#Client
22:30:30FromDiscord<dom96> this has a pretty nice example

23:44:15FromDiscord<RattleyCooper> I feel like I'm blowing this chat up so I apologize... But does anybody know how to read user input without new lines being added to CLI? Not sure if this is a windows-specific issue but the following code outputs onto multiple lines. I'm making a command line app and want values to update over the top of old values instead of outputting to new lines.
23:44:32FromDiscord<RattleyCooper> while user_input in exit_commands == false:↵ stdout.write("\rsome shell> ")↵ user_input = stdin.readLine().strip()↵ stdout.write("\r" & user_input)
23:46:13FromDiscord<ElegantBeef> So you want to print over the user input line?
23:46:50FromDiscord<RattleyCooper> I want to output to the line and then overwrite what was output
23:46:59FromDiscord<ElegantBeef> `cursorUp`
23:47:02FromDiscord<ElegantBeef> from `terminal`
23:47:31FromDiscord<RattleyCooper> Aaah, thanks!
23:47:32FromDiscord<ElegantBeef> Or checkout illwill/ncurses for finer control
23:51:09FromDiscord<Zoom> How to deal with `{.requiresInit.}` propagation throughout the code? I'm constructing an object (`func init(): Foo`) where one of the fields is of a type with `requiresInit`. The field gets initialized with the proper func later in the proc, but I get the warning on the first use of the `result` in `init()`.
