00:14:02FromDiscord<timotheecour> hello... is there a way to `{.compile: "foo.cpp".}` from a `main.nim` file compiled with `nim c main` ? (besides doing it "manually" via `gorgeEx`)

01:00:33FromDiscord<ElegantBeef> In reply to @Esther "Q on that topic": Yes let variables have addresses but you have to use `unsafeAddr` to access them, though that is subject to change
01:01:04FromDiscord<ElegantBeef> Seeing timothee use discord scares me, is the end nigh?

01:16:36FromDiscord<timotheecour> lol why? gitter seems both dead and a memory hog
01:22:46FromDiscord<demotomohiro> Here is example that let variable doesn't have address as it is assigned to register:↵https://godbolt.org/z/zddW1Pr4e↵But you can use unsafeAddr to that variable.↵https://godbolt.org/z/bMnd3YGqK

03:11:30FromDiscord<Esther> In reply to @zetashift "Like https://nim-lang.org/docs/system.html#addr,T y": I mean that gets the address if it exists and fails to compile if it doesn’t — how do I know whether using addr is legal without actually trying to compile?
03:25:55FromDiscord<ElegantBeef> If it's a `var` `addr` and `unsafeaddr` will work, if it's a `let` only unsafe will, if it's a const neither will

04:49:36FromDiscord<impbox [ftsf]> aww you can't get the address of a const? that's no fun
04:49:47FromDiscord<Rika> how would that work?
04:49:57FromDiscord<Rika> how do you get the address of a literal
04:50:08FromDiscord<impbox [ftsf]> well it's stored in memory somewhere right?
04:50:29FromDiscord<ElegantBeef> There is an RFC which would let you store values in the rom so they'd be addressable
04:50:55FromDiscord<ElegantBeef> Remember impbox consts are copied into the code where they're used
04:51:01FromDiscord<Rika> its just kind of strange; the usual use case for getting the address is to mutate it
04:51:04FromDiscord<impbox [ftsf]> (didn't know this)
04:51:14FromDiscord<impbox [ftsf]> sometimes you just want to read it
04:51:21FromDiscord<Rika> In reply to @ElegantBeef "Remember impbox consts are": still; the value is found somewhere
04:51:40FromDiscord<ElegantBeef> Anywho, rom based `let`s 😄
04:52:07FromDiscord<impbox [ftsf]> i'd assumed const just puts it in the data section of the executable where you can reference it, but that's probably a silly assumption
04:52:22FromDiscord<impbox [ftsf]> sounds like that's what the RFC is for

05:35:13FromDiscord<ElegantBeef> If you're on windows your anti virus will most likely think it's a virus and remove it
05:35:33FromDiscord<ElegantBeef> It's a false positive and in no way actually a virus 😄
05:36:26FromDiscord<her0me> Okay, yeah
05:37:04FromDiscord<her0me> I got it to work with the zip file and such, but my friend couldn't

06:03:29FromDiscord<ElegantBeef> Hey me
06:03:35FromDiscord<hamidb80> what's newRuntime ?
06:04:21FromDiscord<hamidb80> i had chat with haxscramer
06:04:32FromDiscord<ElegantBeef> It's changes under the hood to support orc/arc afaik
06:04:54FromDiscord<hamidb80> that openArray behaves diffrently with `seq`
06:05:01FromDiscord<hamidb80> let me find that chat
06:05:24FromDiscord<hamidb80> In reply to @haxscramper "it looks like `seq`": here
06:06:31FromDiscord<hamidb80> In reply to @ElegantBeef "It's changes under the": but i used default GC in that issue
06:07:00FromDiscord<hamidb80> https://github.com/nim-lang/Nim/issues/18005
06:07:14FromDiscord<ElegantBeef> I was just profiling and seeing what sticks, you can enable the newruntime manually, adding important information
06:08:58FromDiscord<ElegantBeef> But yea with either `orc/arc` or `--newRuntime` you get https://media.discordapp.net/attachments/371759389889003532/842282250128457738/unknown.png
06:09:32FromDiscord<ElegantBeef> And it optimized away again using arc/orc 😄
06:11:48FromDiscord<hamidb80> question
06:12:06FromDiscord<hamidb80> if i find that my issue is duplicated
06:12:18FromDiscord<hamidb80> should i close my issue?

06:39:41FromDiscord<PressF> Ideally both
06:39:54FromDiscord<PressF> 😂
06:40:22FromDiscord<PressF> A tonejs wrapper would do the job
06:40:36FromDiscord<ElegantBeef> Well pitter patter
06:41:11FromDiscord<Rika> Get on it, beef
06:41:21FromDiscord<ElegantBeef> it's get at er
06:41:57FromDiscord<ElegantBeef> i'd just support it natively and make people do wasm calls for using it
06:42:46FromDiscord<ElegantBeef> Hey i didnt say i'd do it 😛
06:44:21FromDiscord<Rika> Do it
06:44:32FromDiscord<PressF> I guess I'll do it one day hahahaha
06:44:44FromDiscord<Rika> And that one day is today
06:44:47FromDiscord<ElegantBeef> Wrapping tonejs doesnt look like too much work, so yea
06:44:47FromDiscord<Rika> Now get to it

06:48:31FromDiscord<PressF> In reply to @Rika "Fuck tests do it": It's a physics test about waves so it technically is pre-work study about audio
06:48:49FromDiscord<Rika> Waves? That sounds like high school stuff though
06:49:16FromDiscord<PressF> In reply to @Rika "Waves? That sounds like": Yup 12th grade (last year of highschool)
06:49:36FromDiscord<Rika> What no way that’s fuckin 10th grade shit when I took physics
06:49:41FromDiscord<Rika> Man fuck okay
06:49:55FromDiscord<PressF> It's a global test from 10th to 12th
06:50:05FromDiscord<PressF> Yup my teacher is crazy
06:50:27FromDiscord<Rika> Okay

10:34:59FromDiscord<Esther> In reply to @impbox "well it's stored in": I thought they were sort of equivalent to constexpr in c++
10:39:08FromDiscord<Esther> Do consts in nim actually make it to the emitted c code at all?
10:40:55FromDiscord<Rika> im pretty sure its essentially equivalent to a define in c
10:42:05FromDiscord<Esther> Equivalent sure but do consts result in #defines in the c code?
10:42:13FromDiscord<Esther> I guess I could test but I’m away from my computer ahah
10:43:30FromDiscord<Rika> not defines, but i think they just get substituted
10:51:49*Vladar quit (Remote host closed the connection)
10:59:03FromDiscord<exelotl> it depends on the const and how it's used. E.g. if you `echo MyConstInt` that'll be substituted, but if you do like `echo MyConstArray[i]` it'll generate a const array in the C code once and index it

11:34:58FromDiscord<🍍phylum🍍> hey I'm trying to compile a nim program on an exotic system, setting --gcc.exe and --gcc.linkerexe it looks like everything should be ok. I think NIM_INTBITS is being set to 64 due to the host system, but I need it to be 32
11:35:38FromDiscord<🍍phylum🍍> trying to pass this through with `--passC:-DNIM_INTBITS=32` but it isn't having any impact, is this the right idea?
11:37:47PMunchYou probably need to set the architecture
11:38:14PMunch--cpu:i386 for example
11:38:22FromDiscord<🍍phylum🍍> i did --cpu:mips
11:38:25FromDiscord<🍍phylum🍍> it's a mips cpu
11:38:30FromDiscord<🍍phylum🍍> but that overrode the --gcc.exe
11:38:43FromDiscord<🍍phylum🍍> does order matter?\
11:38:45PMunchAh yes, you need --gcc.mips.exe or something like that
11:38:45FromDiscord<🍍phylum🍍> (edit) "matter?\" => "matter?"
11:39:18PMunchThose are designed so you can put them all in your system wide configuration and then just switch by doing --cpu:mips for example

18:16:14FromDiscord<TurtleP> on threadFunc?
18:16:15FromDiscord<treeform> But you probably would want to use locks to guard the code in the block.
18:16:27FromDiscord<TurtleP> hmm yeah
18:16:41FromDiscord<treeform> you use it as a block mostly: https://github.com/nim-lang/RFCs/issues/142
18:17:29*Prestige joined #nim
18:18:22FromDiscord<treeform> I recommend using channels though. And pass stuff between threads instead (rather then locks).
18:18:42FromDiscord<TurtleP> yeah I looked into that, but it's hard to wrap my head around how those work in nim
18:18:58FromDiscord<TurtleP> especially when I'm used to non-typing channels
18:19:17FromDiscord<treeform> I would create kind of a message object to pass around
18:19:30FromDiscord<treeform> that has everything you want on it and probably an enum type
