05:38:49FromDiscord<Elegantbeef> https://github.com/beef331/truss3d/blob/master/src/truss3D/shaders.nim#L131-L161↵I thought it would be simple to change the shader part of my framework to be type agnostic, oh how i was wrong
05:49:26FromDiscord<Stuffe> I am running into a strange quantum bug in nim, I wonder if someone here has any idea what is going on
05:49:43FromDiscord<Stuffe> So basically my program hangs when I run it, like if it was an infinite loop↵However, when I insert a debugecho to try and figure out what is going on, it doesn't hang anymore↵Even if I just debugecho "hello"
05:50:45FromDiscord<Stuffe> and every time I CTRL+c to stop execution, it shows that execution was at a particular spot in the standard lib sequtils.nim
05:51:15FromDiscord<Stuffe> (its ant the insert function)
05:51:41FromDiscord<Stuffe> if I try to debugecho anything in there it also doesn't hang anymore
05:52:07FromDiscord<Stuffe> I tried to produce a minimum POC, but changing any random thing seems to fix it
06:01:46FromDiscord<huantian> I have no solution but I would like to say that that's weird
06:03:33FromDiscord<Stuffe> yeah

08:43:55FromDiscord<qb> second argument for `createHook` takes a pointer so you could try `cast[pointer](cast[ByteAddress](keymapDetour))`
08:44:14FromDiscord<qb> Not sure if casting to a byteaddress is necessary
08:44:45FromDiscord<FireLite> In reply to @qb "second argument for `createHook`": My question was about third argument, how do I implement it?
08:44:58FromDiscord<FireLite> First and second works perfectly fine
08:45:35FromDiscord<FireLite> But I need to get the original keymap func to not cancel the keyboard input entirely.
08:47:54FromDiscord<Elegantbeef> Is that what you want?

09:03:57FromDiscord<FireLite> Ok, thanks, it works. Now the question is how to I call this original function from hook to unlock the keyboard?
09:04:30FromDiscord<FireLite> Something like `oKeymap(key, held)` throws an error.

09:53:36FromDiscord<4zv4l> arr 1 and arr2 are compile time constant so what's the problem ?
09:54:46FromDiscord<Bung> never seen such a const expr inside generic
09:55:38FromDiscord<4zv4l> there is no generic there
09:55:41FromDiscord<4zv4l> only `int`
09:56:06FromDiscord<Bung> array[N,T]
09:56:29FromDiscord<4zv4l> I don't get what you mean
09:57:37FromDiscord<Bung> the simplest case array[3,int] , what you have is array[max(a.len,b.len), int]
09:57:57FromDiscord<4zv4l> yes
09:58:05FromDiscord<4zv4l> and since `a` and `b` are constants
09:58:11FromDiscord<4zv4l> it can check the length at compile time
09:59:59FromDiscord<Bung> I think there are two point , one: does that const expr really supported in generic, two: if it supported in generic parma, does it also work well with proc result ?
10:00:16FromDiscord<Bung> (edit) "parma," => "param,"
10:01:46FromDiscord<Bung> https://github.com/nim-lang/Nim/issues?q=is%3Aopen+is%3Aissue+label%3AGenerics you see there are 133 opened issues labeled as generics
10:06:26FromDiscord<4zv4l> alright, I'll try another way then

10:16:25FromDiscord<4zv4l> sent a code paste, see https://play.nim-lang.org/#ix=4cUW
10:18:04FromDiscord<Bung> why `array[int, int]` ?
10:19:26FromDiscord<Bung> oh you can try `array_diff[N: static int]`
10:19:38FromDiscord<4zv4l> In reply to @Bung "why `array[int, int]` ?": where ?
10:19:52FromDiscord<Bung> proc def
10:20:21FromDiscord<4zv4l> I don't see see `array[int, int]`
10:20:30FromDiscord<4zv4l> its `array[N, int]`
10:20:50FromDiscord<4zv4l> N is the size not the type
10:20:54FromDiscord<Bung> the message report inffered type
10:21:08FromDiscord<4zv4l> yeah I don't get it
10:21:30FromDiscord<4zv4l> it doesn't translate my array in openArray either
10:21:58FromDiscord<4zv4l> are openArray constant or we can write to them ?
10:22:49FromDiscord<4zv4l> ok I made it works
10:22:50FromDiscord<4zv4l> finally

15:35:41FromDiscord<ezquerra> I got a super basic question: I am converting some Python code which uses a list of objects. In Python when you add an object to a list you are storing a reference to the object while in nim adding to a sequence makes a copy. What is the right way to store a sequence of references to objects? Also, will nim avoid recovering the object memory when the objects go out of scope as long as the sequence of references is still in scope (or vice
15:40:43FromDiscord<Rika> make your objects `ref object`
15:40:45FromDiscord<Rika> yes
15:40:49FromDiscord<Rika> (edit)
15:42:24FromDiscord<Patitotective> sent a code paste, see https://play.nim-lang.org/#ix=4cWy
15:46:23FromDiscord<demotomohiro> You can avoid copy by using ref object, but accessing seq of ref objects can be slower than seq of objects because seq of objects put data contiguously on memory but seq of ref object doesn't.
15:47:19FromDiscord<Rika> less of a "can be" more of a "usually is", dont worry too much about it until you're seeing its effects thoughj
