02:00:56FromDiscord<Stuffe> is there any way to detect on which OS / CPU you are compiling, in a `static` block?
02:01:24FromDiscord<Stuffe> `when defined(macos):` doesn't seem to work, I guess because its a static block
02:05:21FromDiscord<Nlits (Ping on reply)> In reply to @Stuffe "is there any way": I don't think so, the static sandbox is pretty good.
02:07:20FromDiscord<Elegantbeef> https://play.nim-lang.org/#ix=4vGs
02:08:48FromDiscord<Stuffe> hmm, i am not sure why but it doesn't seem to trigger on my m1 mac
02:09:04FromDiscord<Stuffe> I use `defined(macos)`
02:09:10FromDiscord<Stuffe> (edit) "`defined(macos)`" => "`when defined(macos)`"
02:09:21FromDiscord<Stuffe> I guess `macos` is the right keyword, right?
02:09:44FromDiscord<Elegantbeef> `macosx` perhaps?
02:11:38FromDiscord<Stuffe> that didn't work

02:35:29FromDiscord<Stuffe> sorry, another question. Is it possible to walk a directory and load contents of files into a table, at compile time?
02:37:08FromDiscord<Stuffe> I am using the static keyword together with `staticRead`, but I can't get the content into a `const` variable
02:48:53FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=4vGw
02:55:51FromDiscord<Stuffe> It looks like the sort of thing I want, let me try
02:59:31FromDiscord<Stuffe> I can make a const seq with this, not sure how I could make a table
02:59:46FromDiscord<Stuffe> of course I can just make 2 seqs use indexing
03:00:47FromDiscord<Dudugz> You can create a table, iterate over the seq and add the table
03:00:56FromDiscord<Dudugz> (edit) "You can create a table, iterate over the seq and add ... the" added "tô"
03:01:07FromDiscord<Dudugz> (edit) "tô" => "to"
03:02:10FromDiscord<Stuffe> at runtime or compile time?
03:02:48FromDiscord<Dudugz> I didn't see that the code was static, well I won't know the answer because I don't know if tables can be created at compile time
03:03:00FromDiscord<Stuffe> ok, no worries
03:04:43FromDiscord<Stuffe> I don't know the static table syntax, so I will probably just generate 2 seqs unless someone else does. It's not too pretty but its good enough for what I need
03:12:41FromDiscord<Elegantbeef> The static table is just a table
03:17:17FromDiscord<ringabout> Does clang support `-Wl,--build-id=none`? It gives "ld: unknown option: --build-id=none" or it's the fault of macOS?
03:30:28FromDiscord<ringabout> Whatever, needs to diable it on macOS => https://github.com/nim-lang/Nim/pull/21839

05:25:37FromDiscord<Prestige> Is there something weird with generics and using distinct? Trying to figure out what's going wrong here: https://play.nim-lang.org/#ix=4vGN

05:36:19*advesperacit joined #nim
05:36:59FromDiscord<Prestige> How would I go about making a union between these types? Like `SomeSafeSeq[T] = SafeSeq[T] | OrderedSafeSeq[T]` so I could use either in a function
05:37:22FromDiscord<Elegantbeef> You just did
05:37:55FromDiscord<Prestige> When doing this, access to variables is not working - I'll post an example in a sec
05:38:07FromDiscord<Elegantbeef> Did you borrow `.`?
05:38:22FromDiscord<Prestige> On OrderedSafeSet
05:39:39FromDiscord<Prestige> https://play.nim-lang.org/#ix=4vGP
05:41:25FromDiscord<Elegantbeef> hmm borrow might not work properly with generic distincts
05:42:22FromDiscord<Elegantbeef> Honestly here I'd probably use inheritance
05:43:13FromDiscord<Elegantbeef> Since your safeseq is a reference for whatever reason

13:48:34*PMunch joined #nim
13:49:37PMunchHmm interesting. I have this definition in my code: proc atomic_exchange_explicit[T, A](location: ptr A; desired: T; order: MemoryOrder = moSequentiallyConsistent): T {.importc.}
13:49:44PMunchAnd I call it with two arguments
13:50:20PMunchBut the C compiler complains about this: error: macro "atomic_exchange_explicit" passed 4 arguments, but takes just 3
13:50:29PMunch atomic_exchange_explicit(s, x, ((memory_order) 5), (&T1_));
13:50:40PMunchSo for some reason Nim decides to throw in an extra argument..
13:53:09PMunchIt's probably because I try to use it with a reference to a closure..
13:54:43FromDiscord<jtv> Yes, that'd definitely be the state needed to evaluate the closure, so if you're swapping a function pointer, I'd probably not make it a closure...

14:26:12FromDiscord<sOkam!> In reply to @auxym "winim": is it possible to avoid the whole lib, since I only need this one function? 🤔
14:26:39FromDiscord<sOkam!> sent a code paste, see https://play.nim-lang.org/#ix=4vI0
14:31:21FromDiscord<auxym> nim does DCE, only the code you actually use ends up in your binary. And in this case, it's just a call to a dll, so nothing actually gets added to your binary (or just about)
14:36:46FromDiscord<auxym> also, use `import winim/lean`
14:41:49PMunch@jtv, well the whole reason I was trying to pass a closure was to test my synchronization stuff
14:46:29FromDiscord<sOkam!> In reply to @auxym "nim does DCE, only": im more worried about maintaining a dependency that I won't use, than anything else. that's why I was asking
14:46:47FromDiscord<sOkam!> I just need this one function, and won't touch it again
14:47:16FromDiscord<sOkam!> but asking in case there is some build requirements or something, other than linking to the kernel.lib
15:05:15*Notxor joined #nim
15:16:35FromDiscord<auxym> In reply to @sOkam! "im more worried about": you could probably just copy paste that proc declaration in your code. I think, though that `winapi` pragam may be a macro, you'd have to look into what that does. shouldn't need any other build requirements other than linking to kernel32.dll
15:21:17FromDiscord<demotomohiro> In reply to @sOkam! "im more worried about": You can import win32api in the same way as winlean module: https://github.com/nim-lang/Nim/blob/devel/lib/windows/winlean.nim
15:22:55FromDiscord<sOkam!> In reply to @demotomohiro "You can import win32api": but that doesn't import any of those symbols 🤔
15:25:39PMunchOkay, so this simple synchronization thing works: http://ix.io/4vIg
15:26:08PMunchNow just to find the proper guarantees and such to make it generally safe
15:27:03FromDiscord<caravaggio> Is there a nim opencl library?
15:27:12FromDiscord<caravaggio> The one I came across seems deprecated
15:33:30PMunchUgh, the Nimble pkgs2 stuff is so broken: Output: /home/peter/.choosenim/toolchains/nim-#version-2-0/config/nim.cfg(70, 1) Error: invalid package name: /home/peter/.nimble/pkgs2/fungus-0.1.11-b05d8d33453dbd1bf74eb54f47e5d1830863214a
15:33:55PMunchThat's from just trying to choose the #version-2-0 package..
15:47:09PMunchSeems like updating choosenim fixed it

15:49:17FromDiscord<djazz> you havent updated choosenim since June 2022?
15:53:40PMunchThis is my laptop, so probably not
15:55:36FromDiscord<Monolho> how do I cross compile with nake?
15:57:38FromDiscord<Monolho> form linux to windows
16:01:42FromDiscord<jtv> PMunch, the way I'd deal with that in C is I'd be doing atomic swaps on a pointer to a single structure containing the function pointer plus state
16:03:43FromDiscord<jtv> Don't know enough about Nim internals to be helpful sadly
16:06:04PMunch@jtv, that's pretty much exactly what I'm doing in the sample above :)
16:09:11FromDiscord<jtv> From what you're saying, without digging in, it seems like Nim's closure calling convention is to pass the func pointer and state as two params rather than sticking them in one struct
16:09:36FromDiscord<jtv> So to do any type of swap or cas you'd have to get them in a struct yourself I'd assume
16:37:22*progranner quit (Quit: My Mac has gone to sleep. ZZZzzz…)
16:42:46PMunchYup, I just stuck the closure in an object
16:42:54PMunchI shared a paste above
16:43:01PMunchhttp://ix.io/4vIg <- Here it is again
16:44:40PMunchI was just a bit surprised, because the C code generated for a closure is a struct with a callback pointer and a void pointer
16:45:05PMunchSo passing it to a C function I had assumed I would get the object, and not the two pointers added separately
