00:03:55FromDiscord<Elegantbeef> `when type is`
00:04:01FromDiscord<Elegantbeef> I didnt stutter
00:04:27FromDiscord<Elegantbeef> `when client is HcaptchaTaskProxyless: ... elif client is Bleh`
00:05:04arkanoidwhich ident would you give to importcpp foo::bar::Baz ? FooBarBaz? Foo_Bar_Baz? Just Baz?
00:06:45FromDiscord<Elegantbeef> I'd call it baz this isnt cpp
00:07:17arkanoidok but I'm trying to generate importcpp stuff automatically
00:07:36FromDiscord<Elegantbeef> Then `FooBarBaz`
00:08:05FromDiscord<millymox> In reply to @Elegantbeef "I didnt stutter": words perfectly, thank you
00:11:05arkanoidoki
00:11:48FromDiscord<Elegantbeef> You also could emit a type `Foo` and have a template `Bar` that returns another type that `Baz` takes as a first parameter
00:11:52FromDiscord<Elegantbeef> Though that quickly gets messy

00:26:46FromDiscord<that_dude.> Sounds like it has to be used or discarded

00:27:39FromDiscord<millymox> let result = capmonsterclient.join_task_result(task_id)
00:28:07FromDiscord<Elegantbeef> Yes Nim is expressionful which means anything that returns has to be discarded
00:28:44FromDiscord<millymox> okay got it↵↵ discard join_task_hcaptcha(client, task_id)

00:29:15FromDiscord<millymox> any article or docs on how discarding works? Either i haven't been paying attention or ive never seen this in other langs
00:29:37FromDiscord<Elegantbeef> https://nim-lang.org/docs/manual.html#statements-and-expressions-discard-statement
00:29:46FromDiscord<Elegantbeef> It's literally just "I do not care about this value"
00:29:53FromDiscord<that_dude.> Discard is kinda like pass in python, but it also swallows anything you throw into it
00:30:31FromDiscord<Elegantbeef> Yea it's passingly similar to pass 🙂
00:30:52FromDiscord<Elegantbeef> It's used a lot like pass, but technically in Nim any AST can be used like pass

00:33:22FromDiscord<Elegantbeef> Also why the hell are you still doing `if client is`
00:33:44FromDiscord<millymox> mistake lmao i was going to change it
00:33:50FromDiscord<millymox> i forgot though
00:34:27FromDiscord<that_dude.> Overloading also plays nicer with documentation
00:34:51FromDiscord<Elegantbeef> Overloading is just better than logic internally
00:35:07FromDiscord<Elegantbeef> Generally `when X is T` is just a sign you're doing manual dispatching, which is awful
00:36:02FromDiscord<millymox> im confused lmao
00:36:05FromDiscord<millymox> you told me to do when
00:36:10FromDiscord<millymox> now don't do that?

00:37:06FromDiscord<that_dude.> Im pretty sure it was recommended as long as all the logic inside is the same for each type
00:37:19FromDiscord<millymox> oh okay
00:37:22FromDiscord<Elegantbeef> I'm not here to code people's projects, I'm here to mock people's code!
00:37:26FromDiscord<millymox> idk what overloading is so

01:46:23FromDiscord<Elegantbeef> Right, still the best path
01:46:43FromDiscord<Elegantbeef> You no longer need to do `kind: x, fieldName: y`
01:46:43FromDiscord<spotlightkid> Can a template help?
01:46:49FromDiscord<Elegantbeef> it could
01:46:58FromDiscord<JeysonFlores> which communication protocol is it?
01:47:07FromDiscord<spotlightkid> OSC
01:48:27FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=4yS6
01:48:45FromDiscord<Elegantbeef> You also could use a macro if you really wanted to automate the branch selection, but alas
01:52:07FromDiscord<spotlightkid> Thanks, I'll try your template tomorrow. It would have probably taken me quite some time to come up with a working template on my own. I don't have any practice iwriting templates (yet).
01:52:21FromDiscord<Elegantbeef> No problem, they're not too bad
01:56:03FromDiscord<JeysonFlores> @spotlightkid Is the repo of the project public?
01:56:41FromDiscord<spotlightkid> not yet, I only started it in earnest yesterday
02:00:26FromDiscord<spotlightkid> I did an implementation for (Micro)Python once, but Python's dynamic typing makes this particular problem easier, so I can only translate some parts to Nim. https://github.com/SpotlightKid/micropython-osc
02:04:25FromDiscord<JeysonFlores> looks neat. Can the OSC protocol handle complex types (lists/arrays, maps)?
02:07:35FromDiscord<spotlightkid> only arrays and byte blobs
02:08:37FromDiscord<spotlightkid> It was designed for communication between and control of interactive gadgets and electronic musicals instruments (synths etc.) and lighting and so on.
02:08:51FromDiscord<Elegantbeef> Well that's technically sufficient to represent all types
02:08:53FromDiscord<spotlightkid> These mostly only need ints and floats
02:09:02FromDiscord<Elegantbeef> You just need to apply your own mapping ontop 😄
02:09:29FromDiscord<spotlightkid> yeah, you could put a msppack msg into a blob
02:09:55FromDiscord<spotlightkid> That's what I do when I use MQTT
02:10:01FromDiscord<Elegantbeef> Well without even going that low level you can represent atleast non cyclical graphs
02:10:14FromDiscord<Elegantbeef> You just expand it into storing the data sequentially
02:11:06FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=4ySa
02:13:25FromDiscord<spotlightkid> OSC is rather under-specified. It only specifies the msg format, the data types and the format of the message address and timestamps. Communication partners have to agree what message endpoints exist and what types they expect. There's no discovery or reflection.
02:14:28FromDiscord<spotlightkid> maybe a reason why it never really took of. But it's often used for communication between sound engines and controllers.
02:15:48FromDiscord<spotlightkid> Elegantbeef\: BTW, your template works nicely (couldn't wait to try it out). But now I must sleep.
02:16:06FromDiscord<Elegantbeef> No problem, almost like I know how to write Nim 😛

04:27:25FromDiscord<michaelb.eth> In reply to @gogolxdong666 "Why does this gcsafe": just curious, do you know for certain if your code indented under `{.gcsafe.}:` in the body of your `proc connect` is actually gc safe?
04:28:01FromDiscord<Elegantbeef> No locks, no sync logic, of course it's gcsafe! 😛
04:29:47FromDiscord<michaelb.eth> I was on a team that was new to Nim and we didn't know what we were doing at the time, but someone/s "learned" that if you put `{.gcsafe.}:` above your code the compiler is complaining about and indent your code under that, then voila! the code compiles and you can go on about your business, problem solved.

09:08:17FromDiscord<voidwalker> Can it ? then why does rust win all the entries here: https://programming-language-benchmarks.vercel.app/rust-vs-nim
09:08:56FromDiscord<Elegantbeef> Cause the implementations differ
09:09:36FromDiscord<voidwalker> do some PR then pls: https://github.com/hanabi1224/Programming-Language-Benchmarks/tree/main/bench/algorithm
09:09:45FromDiscord<elamandeep> hey @voidwalker acutally bot is right
09:09:49FromDiscord<Elegantbeef> Like cmon the mandlebrot for rust uses simd
09:09:54FromDiscord<jmgomez> The question is can C/C++ be as fast as Rust/Zigs? If yes, Nim can too 😛
09:10:56FromDiscord<elamandeep> In reply to @jmgomez "The question is can": so nim is like typescript right?
09:11:21FromDiscord<elamandeep> typescript too complies into js
09:11:27FromDiscord<elamandeep> (edit) "js" => "javascript"
09:11:43FromDiscord<voidwalker> oh yeah, the json serde thing uses std/json, which is a lot slower than jsony. Wonder who wrote those
09:12:18FromDiscord<Elegantbeef> It's not really like typescript
09:12:50FromDiscord<Elegantbeef> Yea a lot of these benchmarks use simd
09:13:01FromDiscord<Elegantbeef> Like the fuck is the point in comparing languages if you use simd in one but not all
09:13:13FromDiscord<Elegantbeef> I mean benchmarks are pointless anyway
09:13:20FromDiscord<Elegantbeef> But the fuck
09:13:46FromDiscord<elamandeep> benchmarks are pointless. I didn't understand'
09:13:52FromDiscord<elamandeep> (edit) "understand'" => "understand"
09:14:26FromDiscord<Elegantbeef> Programming language benchmarks are useless
09:14:26FromDiscord<Elegantbeef> They do nothing but show who can be more clever with code
09:16:45FromDiscord<voidwalker> well they should have equally (maxxed out) clever coders to write them. and no simd/asm, of course. well, those should be treated as a separate benchmark maybe
09:18:41FromDiscord<jmgomez> In reply to @elamandeep "so nim is like": No because it isnt a superset but it compiles to them instead. BTW it can also compile to js
09:18:42FromDiscord<elamandeep> ok. I found nim is similar to python. I'm planning to build tools around javascript and python. I'm sure i will be using nim of that.
09:19:16FromDiscord<elamandeep> (edit) "of" => "for"
09:19:41FromDiscord<elamandeep> In reply to @jmgomez "No because it isnt": ok
09:19:46FromDiscord<elamandeep> (edit) "ok" => "great"
09:20:11FromDiscord<Elegantbeef> Well any smart programmer looks at Nim and goes "oh a system language" and carries on not carrying about perceived performance 😄
09:20:12FromDiscord<jmgomez> In reply to @Elegantbeef "Programming language benchmarks are": we should write a GPU backend and start playing with their rules
09:22:55FromDiscord<odexine> In reply to @voidwalker "well they should have": How should one decide on which concepts are allowed to be in the same “category” of benchmark
09:23:08FromDiscord<Elegantbeef> Fuck it just use opencl and call it a day
09:23:09FromDiscord<odexine> And how does one decide whether one piece of code is idiomatic, if that is a criteria
09:23:19FromDiscord<Elegantbeef> "This implementation relies on opencl, it do the good"
09:23:48FromDiscord<elamandeep> can we use nim on the web?
09:23:54FromDiscord<Elegantbeef> It's a system language one could argue idiomatic is whatever solves the problem
09:23:55FromDiscord<odexine> Yes
09:24:03FromDiscord<demotomohiro> Some programming benchmarks are unfair. Some implementation use multithreading, SIMD, different size of int / float size or even different algorithm.↵All implementation should follow same rule and implemented in same condition to be fair.↵Also, popular language likely get good code from good programminger, while less popular one get less contribution and likely get poor code.
09:24:23FromDiscord<odexine> In reply to @Elegantbeef "It's a system language": Exactly the point, idiomatic isn’t something that can be easily determined and can vary depending on the scenario
09:24:47FromDiscord<elamandeep> ohk
09:24:48FromDiscord<Elegantbeef> Or we can just disregard programming benchmarks and fiddle with ourselves in the fields as it's a more useful application of time
09:25:05FromDiscord<odexine> In reply to @demotomohiro "Some programming benchmarks are": In such case, are we benchmarking the language (what does it mean to benchmark a language?) or the compiler?
09:25:49FromDiscord<Elegantbeef> There is nothing to learn when drag racing with a car that is intangible
09:26:37FromDiscord<Elegantbeef> If you want to compare how compilers/languages handle specific things go right ahead, but do not under the guise of empiricism pretend to be able to determine which is better
09:27:35FromDiscord<Elegantbeef> To me language benchmarks attempt to attribute statistics to something that is not really measurable, what is the nim solution to mandlebrot
09:29:48FromDiscord<Andreas> regarding performance, i just started benchmarking a lock-free Hash-Trie - does anybd. have access to a NUMA-machine ? My i5 has 4-cores/8-threads..

12:23:14FromDiscord<spotlightkid> Maybe, but not more.

15:51:16FromDiscord<jmgomez> In reply to @millymox "Thank you, not sure": It is
15:52:14FromDiscord<jmgomez> It can be used for "native" mobile dev too via React Native. Although that's more involved

16:24:14arkanoidI have a question. If C++ class Foo has constructor Foo(short bar) {..} imported in nim as constructFoo, is still legal to call "var foo = Foo()" instead of "var foo = ConstructFoo(42)" ?
16:27:17FromDiscord<jmgomez> it is legal but it wont call the imported constructor but the default one. As long it isnt deleted you are fine (with an extra call)
16:28:24arkanoidthen I've a nim codegen bug
16:30:04arkanoidI'm opening an issue on github, but I have no idea which title to use for the issue. I am not a C++ programmer, would you give me an hint please? https://termbin.com/qr6v
16:31:44FromDiscord<jmgomez> That's not a bug
16:32:08FromDiscord<jmgomez> You deleted the default constructor by adding another
16:32:59arkanoidthat would not explain why case OPT = 2 works
16:33:59arkanoidalso case OPT = 4 shows global vs local context codegen issue stable vs devel
16:34:13FromDiscord<jmgomez> In reply to @arkanoid "also case OPT =": this one I fixed not so long ago
16:34:26FromDiscord<jmgomez> In reply to @arkanoid "that would not explain": probably copyMem
16:34:32FromDiscord<jmgomez> so it isnt calling it
16:35:00arkanoidit a compilation issue, not runtime
16:36:05FromDiscord<jmgomez> Dont follow what you are trying to say
16:36:26arkanoidnevermind, as I said I am not a C++ programmer so I'm confused here
16:36:33FromDiscord<jmgomez> no worries
16:37:47arkanoidwhy case OPT = 2 works in global context, but not in local context, if I have deleted the default constructor by adding another?
16:40:27arkanoidif it's not a bug, I'll post in into the forum. I've spent quite some time on this problem and I think it's relevant for other people like me trying to wrap C++
16:41:04FromDiscord<jmgomez> Not sure, it may be. Didnt notice that. Can you post the generated code of both?
16:41:26FromDiscord<jmgomez> Likely the way it's forward declared
16:45:32arkanoidpick case
16:45:37arkanoid+ nim version
16:45:48arkanoidI'll post generatec cpp for those
16:47:20FromDiscord<jmgomez> The one you just said, that works on global and dont in local
16:48:54arkanoidok, would be case 2 vs 3, case 2 works for both stable and devel, case 3 fails on both, but returns different error for stable vs devel
16:49:02arkanoidI'll use stable here then
16:49:41*xet7 quit (Quit: Leaving)
16:51:14arkanoidcase 2 - stable: https://termbin.com/c9tt , error: mbugg.nim.cpp:77:17: error: no matching function for call to ‘MyClass::MyClass()’
16:51:37arkanoidsorry I mean case 3
16:53:10arkanoidthis is case 2 - stable (that works): https://termbin.com/w66ze
16:54:35FromDiscord<jmgomez> It works by coincidence really
16:54:39FromDiscord<jmgomez> `N_LIB_PRIVATE MyClass objbugg_6 = {0}`
16:55:04FromDiscord<jmgomez> it's calling the constructor you defined without intending to. If you add another parameter probably it will fail
16:57:15FromDiscord<jmgomez> You can ask in #internals or forums or in gh issues if it's the intended behaviors. Im not familiar with how the logic of `{}` is expected to work in Nim
16:57:45arkanoiddoes it mean that case OPT = 2 sould fail in both stable and devel like case OPT = 3 as I have deleted the default constructor by adding another?
16:58:50NimEventerNew thread by giaco: Wrapping C++ classes and constructors lead me to compilation errors global vs local, stable vs devel, see https://forum.nim-lang.org/t/10294

17:00:50FromDiscord<jmgomez> In reply to @arkanoid "does it mean that": No, it should not follow the C++ rules as it cant know. You are the one that has the tools for working around them
17:07:03arkanoidI've been staring on your last line for 5 minutes and yet I don't get the meaning, lol
17:07:29arkanoidseems like a "you can do it, nim!"
17:08:25FromDiscord<jmgomez> There is no way the Nim compiler knows that you deleted the constructor
17:12:17arkanoidthen OPT = 2 should faul

17:14:43arkanoidyes I got it, I'm just pointing out that working by chance is not consitent
17:15:28FromDiscord<jmgomez> What you need to know if the `{}` rules and IMO what you should ask about

21:11:59FromDiscord<Andreas> @elegantbeef hey, i'm struggling with smth. rather simple : i need to create a type depending on some parameter. There are types `A1,A2,A3` and depending on some value the initializer-proc will return `A1` or `A2` or `A3` - all types satisfy a `concept` and i tested all of them solo. But no matter how i try, i cannot make this work ? I don't want to make this into a variant-type and i assume that the common way to do this might be a template -
21:12:35FromDiscord<Elegantbeef> Are the parameters static?
21:13:11FromDiscord<Andreas> In reply to @Elegantbeef "Are the parameters static?": no, dynamic.. its `arity` and `depth` both ints
21:13:25FromDiscord<Elegantbeef> So you need runtime logic and cannot return different types
21:13:36FromDiscord<Elegantbeef> Types are static
21:13:53FromDiscord<Elegantbeef> Are the parameters runtime or compile time
