01:45:40FromDiscord<Robyn [She/Her]> In reply to @heysokam "what's the best way": why would the packed pragma change anything?
01:47:28FromDiscord<heysokam> In reply to @battery.acid.bubblegum "why would the packed": then reword the question and the question still remains 🤷‍♂️
01:48:24FromDiscord<Robyn [She/Her]> hmm could look at frosty by disruptek (iirc), or flatty by treeform iirc?
01:49:55FromDiscord<heysokam> binny doesn't have anything for structs, afaik
01:50:05FromDiscord<heysokam> if it does, I haven't seen it
01:51:04FromDiscord<heysokam> I guess the question could be reworded into:↵"how do I turn a struct into a char list without changing the layout"
01:59:08FromDiscord<Robyn [She/Her]> In reply to @heysokam "binny doesn't have anything": flatty, not binny
01:59:23FromDiscord<Robyn [She/Her]> In reply to @heysokam "I guess the question": into a char list?
01:59:53FromDiscord<heysokam> In reply to @battery.acid.bubblegum "flatty, not binny": doesn't have it either
01:59:59FromDiscord<heysokam> at least I didn't see it
02:00:08FromDiscord<heysokam> frosty does have it, but its macro-based
02:00:37FromDiscord<Robyn [She/Her]> hm, do you care about transferring this over the network or between machines? if not, you could do `cast[array[sizeof(T), byte]](obj)`
02:01:01FromDiscord<Robyn [She/Her]> tho, gl with pointers or references, you'll have to implement custom logic for them
02:01:11FromDiscord<Robyn [She/Her]> strings and sequences also would need custom logic
02:01:24FromDiscord<heysokam> packed does not work with references anyway, so no issues
02:01:34FromDiscord<Robyn [She/Her]> atp, you should just make a simple dumper and loader using the fieldPairs iterator
02:01:46FromDiscord<heysokam> and I dont need dynamic storage, its all C-like
02:01:56FromDiscord<Robyn [She/Her]> gotcha, have fun then o7
02:02:07FromDiscord<Robyn [She/Her]> In reply to @battery.acid.bubblegum "hm, do you care": this should work, in theory
02:05:10FromDiscord<heysokam> doesn't array have a length in nim?
02:05:39FromDiscord<Robyn [She/Her]> arrays have a static length, hence why `sizeof(T)` is used
02:05:50FromDiscord<heysokam> but they have a length
02:05:50FromDiscord<Robyn [She/Her]> T being the type you're using
02:06:02FromDiscord<Robyn [She/Her]> yeah, they do
02:06:08FromDiscord<Robyn [She/Her]> do you want it as a sequence?
02:06:15FromDiscord<heysokam> if you turn something into an array, and the array has a length, then what bytes are casted into the len?
02:06:24FromDiscord<Robyn [She/Her]> what
02:06:41FromDiscord<heysokam> the length number lives somewhere
02:06:48FromDiscord<Robyn [She/Her]> no, not at runtime
02:07:39FromDiscord<Robyn [She/Her]> the `array` in Nim is similar to the array types in C, (excluding the variable length arrays in C now) the size is known at compile time
02:09:44FromDiscord<heysokam> C arrays have no len
02:10:11FromDiscord<heysokam> they must be indicated separately. so I don't see much similarity, beyond the array part 🙂
02:11:28FromDiscord<Robyn [She/Her]> In reply to @heysokam "C arrays have no": `char name[32]`
02:12:16FromDiscord<Robyn [She/Her]> that's an array of 32 characters, length is compile time info only, that looks the same as `array[32, char]` in Nim, to me
02:13:36FromDiscord<heysokam> yea, but `name.len` is not a thing in C
02:13:50FromDiscord<heysokam> while that is valid nim code, even at runtime
02:14:53FromDiscord<Robyn [She/Her]> In reply to @heysokam "while that is valid": can't you do `sizeof(name)` in C?
02:16:15FromDiscord<Robyn [She/Her]> either way, i feel like `len` on `array` in Nim doesn't say anything about it being runtime or no
02:16:48FromDiscord<.tokyovigilante> sent a code paste, see https://play.nim-lang.org/#pasty=niImCOFu
02:17:05FromDiscord<Robyn [She/Her]> you can do `myArr.I` and it'll return the size of it, too
02:18:44FromDiscord<.tokyovigilante> `info.imageUsage = VK_IMAGE_USAGE_COLOR_ATTACHMENT_BIT;` works fine
02:26:49FromDiscord<heysokam> In reply to @.tokyovigilante "`info.imageUsage = VK_IMAGE_USAGE_COLOR_ATTACHMENT_": for vulkan flags, enum sets are invaluable
02:27:34FromDiscord<heysokam> if you have control over the wrapper, they are fully compatible with C, so if you have the bindings take an enum set then you'll be able to send them directly
02:27:55FromDiscord<heysokam> without having to use setBit and friends, just `imageUsage.incl`
02:34:02FromDiscord<heysokam> In reply to @battery.acid.bubblegum "can't you do `sizeof(name)`": sizeof relies on null termination
02:34:11FromDiscord<heysokam> afaik
02:36:47FromDiscord<.tokyovigilante> In reply to @heysokam "without having to use": Thanks, I'm using Volk with a Futhark-generated wrapper currently, are you able to elaborate on that a bit? I haven't seen an enum set documented anywhere.
02:38:52FromDiscord<heysokam> sent a code paste, see https://play.nim-lang.org/#pasty=cVGAqzfv
02:39:31FromDiscord<heysokam> shouldn't need the converter casts if you have control over the bindings
03:14:58Amun-RaRobyn: you can't use sizeof(name) in C unless name is an array and not a pointer
03:15:56Amun-Ra(and it'll still return the size of an array and not a string length)
03:20:55FromDiscord<.bobbbob> if I have an object type is there an easy way to do a value based == function like repr for strings or do I have to do a custom overload?
03:21:15FromDiscord<Elegantbeef> `==` is already value based
03:21:46FromDiscord<.bobbbob> oh so it just werks?
03:23:09FromDiscord<Elegantbeef> Assuming all your types internally of the object are `==`
03:23:38FromDiscord<Elegantbeef> if you have `a: ref int` of course it won't be a value comparison
03:24:34FromDiscord<.bobbbob> ah if it's a ref object does it compare the address? in which case I would need an overloaded ==?
03:24:48FromDiscord<Elegantbeef> Of course
03:25:00FromDiscord<.bobbbob> ok

11:19:50FromDiscord<tauruuuuuus> just for my sanity, is there no way of defined a static sub-range type?
11:20:49FromDiscord<tauruuuuuus> something like `static range[0..8]` or `static Natural`? they don't seem to work as I would expect and there is no mention of it in the manual (that I found at least)

16:51:55xtr00is it possible to import non std module in nimscript? It doesnt seem to work. I want to reuse some targets and configs beween sibling projects.
17:01:48*beholders_eye joined #nim
17:05:59FromDiscord<janakali> @xtr00 it seems to work fine for me. Maybe you have problems trying to import `.nims` file? In that case you need to use quotes around filename, e.g. :`import "somename.nims"`
17:06:03FromDiscord<heysokam> yes, but nimble need to know about it. so its not easy to do if you want it on nimble
17:07:12xtr00yes, it is for nimble, now I am starting to find some issues on github around this
17:07:21FromDiscord<heysokam> I had that issue when trying to provide nimble support for `heysokam/confy`, and I couldn't solve it well because of the dependency needing to exist before its called, but calling the file would itself resolve the dependency
17:10:21FromDiscord<heysokam> you could write a nimscript file that resolves your dependency locally, and calls nimble after it↵or any other type of script, really

17:16:39xtr00well, I got something simple to work after simplifying evrything to the max. I think include might be working fine, but the error messages are confusing
17:20:53FromDiscord<heysokam> sent a code paste, see https://play.nim-lang.org/#pasty=pBCbjhwp
17:21:56FromDiscord<heysokam> nimsuggest freaks out about nimscript because it doesn't know it needs to import that module, so every symbol is missing entirely. so the file ends up full of errors because of it
17:23:34FromDiscord<leorize> maybe also open an issue about that...
17:39:38xtr00I found a few issues open already, but I think that my and these usecases are out of nimble's scope. nimble is a package manager not a build system. I need to use the correct tool for the job.
17:39:49xtr00thanks for the help
17:40:57FromDiscord<heysokam> nimble is a buildsystem tool too
17:41:05FromDiscord<heysokam> its just a very lacking one
17:44:13xtr00exactly, for complex projects you need appropriate tools. Even nim uses kock :) that's what I need to do.

17:50:42FromDiscord<heysokam> didn't know there was such a thing as transferable properties. ty leo

18:01:38FromDiscord<heysokam> is there anything resembling an UUIDv4 generator in the stdlib?↵doesnt need to be uuid per se, just something of similar nature

18:04:15FromDiscord<leorize> but it doesn't use a good random source from the description

19:12:43FromDiscord<hamdy34> can I compile nim to c source files?
19:14:24Amun-Rayes, but it's much better to build a library and {.exportc.} functions you need
