01:28:24tokyovigilanteAmun-Ra: I can just import va_list from C thus: type va_list* {.importc: "va_list", header: "<stdarg.h>".} = object
01:29:38tokyovigilanteand then just pass it between Nim and C as a pointer, but my issue is really that an older version of Futhark generated a Nim definitifion for a C function using a va_list, but now uses the {.varargs.} pragma, which isn't interoperable between C and Nim unfortunately. The C header I'm wrapping doesn't seem to have changed
01:33:56tokyovigilanteAh no actually I'm an idiot, I rewrote this using a va_list myself 5 months ago and promptly forgot I'd done it... Sigh. Would be ideal if Futhark could use va_lists but seems this is my fault.

09:00:50tokyovigilanteAmun-Ra: thanks, I don't have a problem with varargs but just can't figure out how to have a nim callback function with them which can be passed to C code as a pointer, ie there's no Nim equivalent to the ... parameter, Nim expects a named vararg type
09:02:22Amun-Rayes, there's not equivalent for those two
09:04:07tokyovigilanteright, that's what I'm struggling with, so I think for this specific case I need to stick with va_list so both Nim and C just see a single pointer

11:38:50FromDiscord<nocturn9x> huh
11:39:02FromDiscord<nocturn9x> how can this possibly segfault when `self.limiter` is an object? https://media.discordapp.net/attachments/371759389889003532/1359492801863094363/image.png?ex=67f7add6&is=67f65c56&hm=29da3cd18c1ae1c9f3b6bfe23b6ff21773ec179d0aea8e5953d43dd220a038c8&
11:39:05FromDiscord<nocturn9x> it's not a ref lol
11:39:13FromDiscord<nocturn9x> and neither is anything contained in what `expired()` calls
11:39:44FromDiscord<nocturn9x> `self` is also an `object`
11:39:53FromDiscord<nocturn9x> hidden pointer tho
11:39:56FromDiscord<nocturn9x> cuz `var SearchManager`

12:16:38FromDiscord<nocturn9x> this contains the values I expect

13:44:46FromDiscord<anuke> Does the standard library have a variable length bitvector anywhere?
13:45:22FromDiscord<anuke> (edit) "bitvector anywhere?" => "bitvector/bitset?"
13:47:14FromDiscord<anuke> There seems to be a `bitsets` module, but it's undocumented and internal
13:47:21FromDiscord<mratsim> no
13:47:51FromDiscord<mratsim> though maybe look for "succinct data structure" since it's the name of those kinds of data structures
13:48:14FromDiscord<mratsim> I have a couple of implementations here and there but they only support setting bits and retrieval
13:49:16FromDiscord<mratsim> In reply to @anuke "Does the standard library": https://github.com/mratsim/nim-project-euler/blob/master/src/lib/bithacks.nim#L34-L65
13:52:33FromDiscord<anuke> Just wondering - is there a reason why it uses a `seq[int]` and not a `seq[int64]`? The Java implementations I've seen use `int64`s - is `int` being `int32` on 32-bit platforms faster for bitsets?
14:16:11*amadaluzia joined #nim
15:07:13FromDiscord<ieltan> In reply to @anuke "Just wondering - is": Cause the size of `int` is platform dependent. On modern platforms `sizeof(int)` is 8 bytes (64 bits), on some it's 4 bytes (34 bits)
15:07:20FromDiscord<ieltan> (edit) "(34" => "(32"
15:08:20FromDiscord<ieltan> It's not necessarily to make int faster but to have compatibility with platforms that doesn't support 64 bits ints
15:10:17*derpydoo joined #nim
15:15:09FromDiscord<anuke> In reply to @ieltan "Cause the size of": I'm aware, but that's not what I'm asking - I'm asking why the `seq` of the bitset isn't always a 64-bit integer.
15:15:37FromDiscord<anuke> `int64` is supported on every platform (aside from perhaps some ancient ones)
15:15:48FromDiscord<anuke> (edit) "`int64` is supported on every platform (aside from perhaps some ... ancient" added "irrelevant"

20:34:54FromDiscord<lainlaylie> In reply to @threefour "Something like this, but": this already works if testPeople is a var and you use mitems. is it a requirement that it works on immutable values?

20:38:56FromDiscord<threefour> My example is minimal, but my applied scenario has a lot of extra boilerplate that I would like to eliminate via a template. So a way to provide the list of objects, the key, and the value, and then have the template handle the boilerplate, is what I'm looking for.
