00:14:28FromDiscord<evader`> which of the available vulkan nim bindings are sanest to use?
00:15:10FromDiscord<evader`> i see 3 but only 2 updated recently, nimgl and clyybber
00:28:01FromDiscord<ElegantBeef> I think the general reception is they're both good
00:28:47FromDiscord<ElegantBeef> Yea i'm uncertain why, if there isnt an issue already probably shoul make one

00:49:05FromDiscord<garett> Hello folks. Is it possible to forward-declare an object type?
00:50:41FromDiscord<garett> For me it would be useful because I want to `include` some platform-specific code that will define the members of the object type, and I want to provide a pointer to it as the public API

03:09:13FromDiscord<Gabben> In reply to @Hi02Hi "if you want that": Above, I showed examples that work with var. I can't understand why in one case it works, in the other it doesn't, even though the same thing is being done.↵I don't want to use ref in such a simple case, ref is more expensive than var
03:24:13FromDiscord<Rika> In reply to @Gabben "Above, I showed examples": the first example returns a copy that is mutable
03:24:21FromDiscord<Rika> ...i believe
03:24:45FromDiscord<Rika> so s is a copy of j
03:27:33FromDiscord<Rika> hm

03:35:47FromDiscord<ElegantBeef> yea the object in two is right but it gets copied on return, i dont know why maybe cause only one owner of a `var` can be had at a time and it already exists with the `one.j`
03:36:04FromDiscord<Rika> it doesnt get copied on return
03:36:09FromDiscord<Rika> it gets copied on assignment to a var
03:36:33FromDiscord<Rika> thats strange
03:36:55FromDiscord<ElegantBeef> That's what i meant but yea
03:37:14FromDiscord<Rika> ah that makes sense i didnt understand what you said

11:56:20FromDiscord<OffenseTeacher> Hey guys, I have been trying to find how to implement Linker options as in C/C++ (ex: ↵#pragma comment(linker,"/export:SystemFunction006=cryptsp_orig.SystemFunction006,41@"))↵↵I have tried to surround it using the emit pragma and it does seem to appear in the generated c code. However it makes no difference in the end. Is there a better way to do it with Nim ?
11:56:34FromDiscord<OffenseTeacher> (edit) "(ex:" => "Ex:" | "comment(linker,"/export:SystemFunction006=cryptsp_orig.SystemFunction006,41@"))↵↵I" => "comment(linker,"/export:SystemFunction006=cryptsp_orig.SystemFunction006,41@")↵↵I"
11:59:42FromDiscord<haxscramper> Have you tried `{.passl: "<linker options go here>".}`?
12:00:25FromDiscord<OffenseTeacher> absolutely not ! Will go read on that
12:00:31FromDiscord<haxscramper> Assuming `#pragma ...linker` has something related to linker though
12:01:00FromDiscord<haxscramper> https://nim-lang.org/docs/manual.html#implementation-specific-pragmas-passl-pragma
12:01:26FromDiscord<OffenseTeacher> I am trying in fact to do dll proxying: https://itm4n.github.io/dll-proxying/
12:03:37*hyiltiz quit (Ping timeout: 260 seconds)
12:04:23FromDiscord<OffenseTeacher> It allows to redirect a program that try to load your dll for a specific function to the legitimate dll's function address. In the example I provided in C/C++, it create a redirection for any call to the SystemFunction006 function -> to the SystemFunction006 function of cryptsp_orig.dll
12:05:39FromDiscord<haxscramper> From https://docs.microsoft.com/en-us/cpp/preprocessor/comment-c-cpp?view=msvc-160#linker I would assume `{.passl:` is fully equivalent
12:06:14FromDiscord<haxscramper> So in your case it would be `{.passl: "/export:SystemFunction006=cryptsp_orig.SystemFunction006,41@".}`
12:07:12FromDiscord<haxscramper> When nim compiles it generates `.json` file with compilation commands in the cache directory (can set it explicitly with `--nimcache`) - you can check if linked options were passed correctly
12:07:37FromDiscord<OffenseTeacher> wow! Thanks I will try it right away. Thanks alot 🙂
12:13:31FromDiscord<OffenseTeacher> I would guess it works a bit differently.. I have tried including the cryptsp_orig.dll in the same folder without success↵x86_64-w64-mingw32-g++: error: /export:SystemFunction006=cryptsp_orig.SystemFunction006,41@: No such file or directory

12:32:22PMunchThat looks like some escaping/file naming issue
13:02:57Zoom[m]Hm. It seems you can't create an immutable array relying on automatic initialization, since `let` requires the explicit init. It's annoying as there's no `initWith` for arrays. Do you think this qualifies as a bug?
13:07:54FromDiscord<haxscramper> I suppose you can create array with let and them `move` it
13:08:15FromDiscord<haxscramper> `let arr = (var arr: array[255, int]; move(arr))`
13:08:48Zoom[m]huh, clever
13:08:50FromDiscord<haxscramper> I'm not sure if you need to `move` there though
13:09:02FromDiscord<haxscramper> Maybe just `arr;` will be sufficient
13:09:08*Edoardo[m]1 joined #nim
13:09:29FromDiscord<haxscramper> But then I don't quite follow what is the use case for this array ... it will always contain identical immutable elements

13:12:48Zoom[m]It's going to be appended (moved perhaps) to another container, so the mutability doesn't really matter, I just default to `let` and noticed I can't :D

13:25:57FromDiscord<Vindaar> also regarding the `foreach`: An alternative for more friendly syntax might be what @mratsim did in loop fusion or nowadays in laser (and now arraymancer).

16:58:43FromDiscord<timotheecour> In reply to @Clonkk "Is it possible to": once https://github.com/nim-lang/fusion/pull/32 will be merged (hopefully in stdlib instead of fusion), you'll be able to efficiently recursively list files/dirs in order (without having to store all results in memory at any point, only at most (N) where N = max entries per dir)
17:12:13FromDiscord<Chem> Multiple inheritance boils down to a vtable with a predefined number of methods right?↵So in theory if Nim emits a struct/class that has an identical number of function pointers in it's vtable in the right order, from a compiler's point of view are they equivalent?↵↵If that is the case, could you do a compile-time check using some kind of macro `mixin`/`extends` syntax that verifies all the member functions are present + have the right

17:39:55FromDiscord<Chem> A bit of an odd usecase but you can emit the C files or obj files to a local directory and then you need to link the RTL in some cases I think↵Other folks will know better
17:40:07FromDiscord<Chem> It's semi-readable in `-danger` mode
17:40:51hendursagaAh. I just would need the API/ABI to be predictable.
17:41:12FromDiscord<Chem> Oh, you control that directly
17:41:23FromDiscord<timotheecour> > So in theory should be possible at compile-time with some work, just not at runtime because of those limitations?↵that's my understanding; see also https://forum.dlang.org/thread/[email protected]?page=1 but not sure it maps well to nim.
17:42:12FromDiscord<Chem> In reply to @timotheecour "> So in theory": I think we're on the same page 😅 , I was experimenting with this, embedding the "extended" class fields inside
17:42:33FromDiscord<Chem> without actually "inheriting" anything -- then trying to interop from C++ with `dynamic_cast<T>` and seeing if it works
17:42:45FromDiscord<Chem> thank you, I will keep digging more on this = )
17:43:52FromDiscord<timotheecour> > Ah. I just would need the API/ABI to be predictable.↵ya, it's no problem, see also `nim --app:lib|staticlib`, or just compile with `nim --hint:cc --hint:link --listcmd` to see the compilation + link commands ; note that the emitted C is not C-idiomatic but indeed readable (as mentioned eariler, even more readable with -d:danger)
17:46:08hendursagaThat sounds workable, I'll go through some more tutorials and see if I have any additional questions :)
17:47:00FromDiscord<timotheecour> (i mean of course, anything is possible, and importcpp classes could be made to support multiple inheritance just for C++ interop, but it's really unclear whether this is a good idea, it's even more clear that there's more useful things to do in nim on the C++ interop side to improve things)
17:54:42FromDiscord<Chem> Yeah that's reasonable. Only reason I ask is in the case of headers where the implementation "requires" multiple inheritance.↵↵But I'm not very familiar with C++ and it could be very possible that if you just have a class with all the same methods, whether you declare the inheritances or not, it will work.
17:54:53FromDiscord<Chem> I should probably test on Godbolt really quick just to see
17:56:21FromDiscord<Chem> I might spend some time working on a Nim adapter for `clang-cpp`/`LibTooling` based codegen from C++ headers, that have been working on for D
18:00:50FromDiscord<timotheecour> maybe create a repo so others can contribute?
18:01:12FromDiscord<VinKer> Hi all, I don't know how many lines are in my file. How do I call the readLine proc ?

18:03:51*MarderIII quit (Quit: Leaving)
18:04:58FromDiscord<VinKer> @timotheecourBut that's a string. I need a seq[string]
18:05:10FromDiscord<timotheecour> `toSeq(lines(f))`
18:05:40FromDiscord<VinKer> Let me check what this toSeq does. Thanks 🙂
18:10:14FromDiscord<VinKer> @timotheecour Thanks, it worked. But if we read the documentation of toSeq, we won't know that it is capable of splitting string into a seq.
18:10:47FromDiscord<timotheecour> it's not splitting a string, read manual section on iterators
18:13:39FromDiscord<VinKer> If it's not splitting a string, then how come the seq is filled with each line on that file. I wonder
18:14:26FromDiscord<Tavon> It's equivalent to↵var a = newSeq[string]()↵for i in lines(f):↵ a.add(i)
18:14:50ForumUpdaterBotNew post on r/nim by piperman7: How to create a file upload server?, see https://reddit.com/r/nim/comments/nfhtxu/how_to_create_a_file_upload_server/
18:15:39FromDiscord<VinKer> That's confuisng, because, the doc of "lines" says that it returns a string. Means all text from the file as a single string.
18:16:34FromDiscord<VinKer> AFAIK, if a string is iterable, then we can iterate each character.
18:16:43FromDiscord<VinKer> Please correct if I am wrong
18:16:56FromDiscord<timotheecour> again, read the manual on iterators, it'll clarify.
18:17:01FromDiscord<VinKer> Okay
18:17:37FromDiscord<timotheecour> (edit) "again, read the manual on iterators, it'll clarify. ... " added "after that, you can ask again here."
18:17:44FromDiscord<timotheecour> (edit) "here." => "here if still unclear."
18:20:38FromDiscord<VinKer> I am sorry to bother you, but I failed to understand what you said. Doc of Iterators say that "Iterates over each item of a"
18:20:56FromDiscord<Tavon> lines returning a string means each iteration of the function will return a string
18:21:44FromDiscord<VinKer> I thought, lines is returning the whole string
18:22:40FromDiscord<VinKer> My bad.
18:23:03FromDiscord<VinKer> The doc of "lines" clearly say that - "iterate over any line in the file f"
18:23:33FromDiscord<VinKer> Thank you guys for your time.
18:38:16FromDiscord<Traveler> Hi, I recently learned about nim and i am interested in getting into this language. In my day to day I interface a lot with python code, and I see that nimpy offers this interfacing with python. The git repo implies that interactions works perfect from python -> nim but not the other way around. The biggest omision seems to be the type export, is anyone here aware of allowing extensions to be seen as classes under python similar to how p
18:42:04FromDiscord<Hi02Hi> Hi, I am not an expert on py<->nim, but i found this talk about it↵It also gives a minimal intro to nim↵https://www.youtube.com/watch?v=IVgNVJdizHg

19:33:27FromDiscord<kunitoki> is this to prevent more new joiners from entering ? 😄
19:34:40FromDiscord<kunitoki> btw, i noticed that Nim doesn't respect immutability when importcpp is involved and there are mistakes in proc constness mapping
19:35:18FromDiscord<kunitoki> not sure if it's normal, but i think it should prevent code from compiling when it doesn't respect invariants
19:35:36FromDiscord<kunitoki> consider this snippet
19:36:43FromDiscord<kunitoki> sent a code paste, see https://play.nim-lang.org/#ix=3nfq
19:36:56FromDiscord<kunitoki> this prints "def"
19:37:06FromDiscord<kunitoki> it compiles and everything
19:37:20FromDiscord<ElegantBeef> Yea i think it explictly states that it doesnt handle immutability for imported types
19:37:21FromDiscord<kunitoki> i was expecting the c++ compiler to boom
19:37:53FromDiscord<kunitoki> it's a ticking bomb, especially if someone forget the `var`
19:38:51FromDiscord<ElegantBeef> Yea i was right https://nim-lang.org/docs/manual.html#statements-and-expressions-let-statement
19:39:57FromDiscord<kunitoki> In reply to @ElegantBeef "Yea i think it": well, in c++ at least if a variable is declared const, mutating it is UB
19:40:57FromDiscord<kunitoki> i will try to compile generated cpp code by nim with ubsan and see what happens. i saw a bunch of C style casts in c++ generated code
19:41:04FromDiscord<ElegantBeef> I'd reason the best way to do this is to wrap the object with a nim object so immutability holds
19:41:08FromDiscord<kunitoki> (edit) "happens." => "happens 😄 ."
19:41:30FromDiscord<kunitoki> yeah probably that's a good idea
19:41:59FromDiscord<kunitoki> anything `import` in Nim ends up being unsafe
19:42:56FromDiscord<kunitoki> also found this today, a SIGSEGV in the compiler
19:42:57FromDiscord<kunitoki> https://github.com/nim-lang/Nim/issues/18042
19:43:25FromDiscord<kunitoki> it's maybe a silly example (not sure if it is even valid)
19:43:38FromDiscord<kunitoki> but at least the compiler should not seppuku 😄
19:44:42FromDiscord<kunitoki> is there a more recent release of the nim compiler after 1.4.6 ?
19:45:52FromDiscord<zetashift> As in stable? No but you can download devel with choosenim
19:45:54FromDiscord<ElegantBeef> The issue is the distinct, there is no other enum 😄
19:46:13FromDiscord<kunitoki> yeah i know it's silly
19:46:50FromDiscord<kunitoki> probably `type X = distict enum Y` crashes as well
19:46:57FromDiscord<ElegantBeef> Yea with invalid indentation
19:47:40FromDiscord<ElegantBeef> Which is a general "you fucked up hard" message sometimes 😄
19:48:24FromDiscord<kunitoki> doh
19:49:13FromDiscord<kunitoki> In reply to @zetashift "As in stable? No": thanks
19:49:26FromDiscord<ElegantBeef> distinct is for creating a same but type different type of an already existing object, so it's expected to error with `distinct enum` 😄
19:49:41FromDiscord<ElegantBeef> (edit) "object," => "type,"
19:50:02FromDiscord<kunitoki> yeah, but i prefer a "you fucked up hard" than SIGSEGV 😄

20:31:55FromDiscord<zidsal> so I'm writing a triplestore (tuple of subject, predicate, object). Currently my `query()` function always returns a sequence of tuples but I'm wondering how I can support selecting specific data e.g. `select subjects where ....'` would instead return a sequence of subjects.↵↵Is there anyway to do something like the following https://play.nim-lang.org/#ix=3nfB
20:36:37FromDiscord<ElegantBeef> Not that i know of, the issue is that the return type is calculated at compiletime but the logic needs to be done at run time, so you need runtime logic to change the behaviour
20:37:03FromDiscord<ElegantBeef> I faced a similar issue with my hseq stuff and i just made a custom macro that allows differentiation internally
20:37:46FromDiscord<ElegantBeef> sent a code paste, see https://play.nim-lang.org/#ix=3nfF
20:38:19FromDiscord<zidsal> are you saying you always return yourT and then you wrote some helper macro's to easily extract the responses once you've run your query??
20:39:07FromDiscord<zidsal> I don't know why I double question marked that, that's not outrageous at all I need sleep
20:40:37FromDiscord<ElegantBeef> Basically it's just expanded into your case body like you have in test, so you need to have an `Option[T]` for each value so you can set it and figure out which you set
20:41:38FromDiscord<zidsal> ah I'm with you now
20:42:14FromDiscord<zidsal> shame I was looking forward to building my own querying language for the in memory database, but it seems pointless now that I can't really define the return types!
20:42:47FromDiscord<ElegantBeef> Yea welcome to static typing 😛
20:43:34FromDiscord<zidsal> pretty sure typescript can handle that so its def possible! who wants to write the rfc to make nim's type system turing complete
20:43:46FromDiscord<zidsal> (edit) "possible!" => "possible for a static typed language!"
20:45:26FromDiscord<zidsal> infact https://github.com/codemix/ts-sql shudders

21:29:59FromDiscord<zidsal> hmm I think I've resigned to having to do this with multiple methods, althought I wonder if I can do something nasty so that its one method that takes a typedesc of either a subject, predicate, object or of any combination of the above (should only be 7 permutations) .↵↵That way it becomes something like `query(SubjectPredicate, "where ....")`
21:30:45FromDiscord<zidsal> if you always have to pass in a typedec then I suspect a macro / template can do this as you provide that info at compile time
21:41:54FromDiscord<zidsal> so something like https://play.nim-lang.org/#ix=3nfP, then I can use a macro to return different stuff depending on the typedesc maybe
21:41:55FromDiscord<zidsal> (edit) "maybe" => "maybe?"
21:57:40FromDiscord<Vindaar> if I understand you correctly, that's already achieved by a regular generic. So what you wrote is almost what simply works: ↵https://play.nim-lang.org/#ix=3nfU↵↵There's a bit of freedom how exactly to write this, but as long as you hand something at CT that determines the return type, it's not a problem

22:15:36kayabaNerveBoth are missing multiple Nim versions :/
22:16:17kayabaNerveAnd choosenim doesn't handle ARM Macs, even just via offloading to Rosetta (I do understand the lack of upstream binaries)
22:18:50kayabaNerveI wrote my own Nim 1.2.12 Dockerfile ages ago, not really an active concern for me, yet the brew thing is as the only alt is having users manually install from a tar. Looks like the brew team themselves wrote and committed all of them? So I'd have to reach out to them?
