01:26:31FromDiscord<Girvo> Hi all 🙂
01:27:25FromDiscord<Girvo> I'm using stew/endians2 to handle some Modbus data, converting two uint8s into an endian-aware uint16, for example. ↵It doesn't handle signed ints though. Any good references for how I should go about it? ↵The specific comments in the library itself mention that under/overflow complicate matters a little
01:33:41FromDiscord<Elegantbeef> I'd say something if i was smart enough to understand why signed ints change anything
01:37:18FromDiscord<Girvo> See thats what I thought too lol
01:37:34FromDiscord<Girvo> sent a code paste, see https://play.nim-lang.org/#ix=4al3
01:38:01FromDiscord<Elegantbeef> Oh the issue is more just using those types increase the chance of going over/under
01:38:29FromDiscord<Girvo> Right. In this case it never will because the slave is generating known-good values. So I could safely add them then?
01:38:48FromDiscord<Elegantbeef> LIkely
01:38:56FromDiscord<Elegantbeef> I do like that `uint8` is there
01:39:02FromDiscord<Girvo> haha same
01:39:04FromDiscord<Elegantbeef> Is it BE or LE, who knows?! ;D
01:39:41FromDiscord<Girvo> One thing I'm dreading is dealing with word-order that differs with byte-order. I'm praying none of the modbus slaves we deal with do that, but sadly it's apparently semi-common
01:40:08FromDiscord<Girvo> I can't for the life of me work out _why_ you would ever want that, but I dunno maybe I'm missing something
01:40:36FromDiscord<Elegantbeef> Those C programmers were on somthing
01:45:59FromDiscord<Girvo> Now to work out how to do a `float` in the same way, with 4 bytes, endian-aware. Maybe it'll work the same way?
01:46:21FromDiscord<Elegantbeef> float32 you mean 😛
01:46:27FromDiscord<Girvo> Indeed 😛
01:46:36FromDiscord<Girvo> Though we may need to deal with float64 as well, apparently
01:46:45FromDiscord<Elegantbeef> `cast[uint32]` then use the same mechanisms as the uint32?
01:47:19FromDiscord<Girvo> Thats basically what I've done. I'll test it and see if it works
01:48:33FromDiscord<xzntrc> whats the best way for writing configs?
01:48:51FromDiscord<Elegantbeef> Depends on your view, you can use json, yaml, toml,....
01:49:13FromDiscord<xzntrc> ah toml
01:49:21FromDiscord<xzntrc> toml is basically .ini right?
01:49:34FromDiscord<Elegantbeef> More standard and more modern yes
01:51:10FromDiscord<Bung> In reply to @Girvo "I'm using stew/endians2 to": I use https://github.com/OpenSystemsLab/struct.nim for handle endians
01:53:27FromDiscord<Girvo> @Bung Oh that looks nice

02:08:46FromDiscord<Girvo> <@&371760044473319454>
02:09:08FromDiscord<Girvo> How would swapBytes work for a float32... treat it all as uint32 then cast at the end maybe?
02:09:30FromDiscord<Girvo> I might dig into your code Bung
02:09:39FromDiscord<Elegantbeef> Likely if strict aliasing doesnt get in your way 😄
02:11:25FromDiscord<Girvo> Yeah lol
02:11:35FromDiscord<Girvo> I'm having fun with the various shift-lefts it relies on
02:13:12FromDiscord<Elegantbeef> Oh i do have to say girvo wasm3 solves most of my issues with the other wasm runtimes 😄
02:13:37FromDiscord<Girvo> Oh thats awesome 😄
02:14:35FromDiscord<Girvo> sent a code paste, see https://play.nim-lang.org/#ix=4ala
02:14:39FromDiscord<Girvo> Trying to special case float32 handling for it
02:14:50FromDiscord<Elegantbeef> You can throw a when inside
02:15:05FromDiscord<Girvo> Yeah I just don't know what the `==` check I'm supposed to do is lol
02:15:10FromDiscord<Elegantbeef> You also could move that to be `x: ExtraEndianint): ExtraEndianint`
02:15:16FromDiscord<Elegantbeef> Oh it'd be `x is float32`
02:15:24FromDiscord<Girvo> Ah! `is` is what i was missing 🙂
02:15:25FromDiscord<Girvo> Cheers
02:15:33FromDiscord<Elegantbeef> then you could have a `func swapBytes(x; float32): float32)`
02:17:22FromDiscord<Girvo> Yeah thats how stew/endians2 handles it
02:17:31FromDiscord<Girvo> Has a whole suite of them for every type it uses
02:20:36FromDiscord<Elegantbeef> I'm quite surprised you havent needed the `is` operator before now
02:32:19FromDiscord<Girvo> I've just not had too do much directly with it tbh
02:32:41*monkeybusiness quit (Remote host closed the connection)
02:32:54FromDiscord<Girvo> Theres a lot less type-level abstraction in this firmware right now, though once the expo is done we'll be going back and refactoring a lot of it
02:43:11FromDiscord<Girvo> Okay so the cast-to-uint32 for float32 handling appears to work, though I've done "little endian" usage as I think the swap bytes implementation is off. I'll test it more when I connect the real slaves to it. But I can get the expected float from my slave simulator
02:43:48FromDiscord<Girvo> Oh lol. The endianness is because Modbus uses "FloatReverse" apparently. Wild.
02:43:52FromDiscord<Elegantbeef> "slave simulator" is an atrocious term used in any other context 😛
02:44:10FromDiscord<Girvo> Haha it gets worse, this is an Active Slave Simulator 😐
02:45:03FromDiscord<Girvo> Hmm. I'm losing some precision across all this somewhere. `1.900` on the simulator is being read back as `1.899999976158142` on the ESP itself. Weird.
02:45:27FromDiscord<Girvo> The simulator doesn't let me be more precise than three decimal places though. Probably a reason for it...
02:46:44FromDiscord<Girvo> The joys of IEEE-734...
02:50:51FromDiscord<Girvo> Is there a way to round to `n` decimals? I know `round` in std/math will do to `0` places obviously
02:52:30FromDiscord<Elegantbeef> Other than formatting, not really, you can do `round(a / 0.00001) 0.000001` but precision be spiteful mistress
02:52:44FromDiscord<Elegantbeef> Those literals should be the same size
02:52:48FromDiscord<Girvo> Yeah, damn. Alright, I
02:53:02FromDiscord<Girvo> I'll look into whether its even a problem, this simulator is a bit funny anyway
02:53:06FromDiscord<Girvo> It might be fine with real data

07:24:38FromDiscord<haxscramper> Strdefine needs to be defined from the compilation

07:25:02FromDiscord<fbpyr> ah ok - I did not find it in the compiler option docs

07:43:26FromDiscord<Elegantbeef> It's in docgen, luckily if you dont want a proc to raise you can just annotated it `{.raises: [].}`

07:43:46FromDiscord<4zv4l> I don't see them
07:43:57FromDiscord<Elegantbeef> `raises: []` means it doesnt raise
07:44:05FromDiscord<4zv4l> so it can always open the file ?
07:44:16FromDiscord<Elegantbeef> It returns a bool if it fails
07:44:43FromDiscord<4zv4l> how do I know if that's because the file doesn't exist or if it's because of permissions ?

08:28:25FromDiscord<Rika> looks likes an internal error though
08:29:10FromDiscord<aruZeta> yes
08:29:58FromDiscord<demotomohiro> that compile error come from gcc. Probably Nim compiler bug or wrapping C lib incorrectly.
08:30:21FromDiscord<aruZeta> i'm not wrapping any lib
08:30:33FromDiscord<aruZeta> unless you mean the nim complier itself
08:30:37FromDiscord<aruZeta> (edit) "complier" => "compiler"
08:33:14FromDiscord<demotomohiro> Then, it might Nim compiler bug
08:33:43FromDiscord<Elegantbeef> The Nim compiler isnt supposed to have any C compiler errors without you causing them directly importing bad C
08:33:44FromDiscord<Elegantbeef> So yes it's a compiler bug
08:34:49FromDiscord<aruZeta> what should I do then
08:35:02FromDiscord<aruZeta> file an issue in the nim github
08:35:12FromDiscord<Elegantbeef> Make a min repro and yep
08:37:09FromDiscord<aruZeta> what do you mean by "min repro"
08:37:20FromDiscord<Elegantbeef> minimum reproduction
08:37:36FromDiscord<aruZeta> ahh ok
08:38:00FromDiscord<Elegantbeef> The best github issues are single files and the fewest lines
08:38:27FromDiscord<aruZeta> will try to make a min repro then
08:38:50FromDiscord<aruZeta> i'm more concerned with what coud I do to fix it tho hmm
08:39:13FromDiscord<Elegantbeef> remove the converter and see if that changes anything
08:39:17FromDiscord<aruZeta> nope

08:40:44FromDiscord<Elegantbeef> Figuring out what causes it will let you work around it
08:40:48FromDiscord<Elegantbeef> I dont know what would cause it
08:41:08FromDiscord<Elegantbeef> Ah found it

09:37:21FromDiscord<aruZeta> ah no it doesn't :/
09:38:19FromDiscord<aruZeta> instead of using a range I could check with an if if the value is between 0 and 100 and raise a Defect, but makes the code more complicated

10:10:56FromDiscord<Rika> okay
10:11:12FromDiscord<soda> i'm curious why you find the idea bad(?)
10:11:33FromDiscord<ache of head> isnt a lot of this stuff already in stl
10:11:33FromDiscord<aruZeta> it's not that he finds it bad, he just asked why
10:11:58FromDiscord<soda> In reply to @c1m5j "isnt a lot of": It is, but the stl is always so annoying to use
10:12:09FromDiscord<ache of head> 🤔
10:13:12FromDiscord<soda> it's very verbose an also achieving something often requires multiple steps.↵I want string.split(char delim) to generate a dynamic array of vectors, no questions asked
10:13:21FromDiscord<soda> (edit) "vectors," => "strings,"
10:13:29FromDiscord<soda> Like it does in nim
10:13:38FromDiscord<ache of head> maybe its verbose for a reason?
10:14:10FromDiscord<soda> I wish they shared those reasons
10:14:23FromDiscord<ache of head> who did
10:14:36FromDiscord<soda> whoever makes the stl
10:14:36FromDiscord<Rika> you know i misunderstood you when you said "reimplement"
10:14:41FromDiscord<Rika> rather implement
10:14:53FromDiscord<soda> err my bad, you are right, they are different
10:14:55FromDiscord<Rika> i thought you meant that you were gonna write the stdlib for nim in c++
10:15:09FromDiscord<Rika> that would be truly strange really
10:15:46FromDiscord<soda> no i meant i want nim-style functionality in C++
10:15:57FromDiscord<soda> the other way around, kinda
10:16:04FromDiscord<ache of head> why not just write in nim?
10:16:22FromDiscord<ache of head> unless it’s like a school project and there are restrictions or smth like that
10:16:32FromDiscord<Rika> yeah i know im just saying thats why i asked why

11:31:20FromDiscord<Generic> that error is pretty bad, but I don't think macros should throw exceptions
11:31:40FromDiscord<Generic> if you want to signal an error, use the error proc from the macros module
11:32:15FromDiscord<Generic> it generates a compile error and you can optionally pass a NimNode to it, which's location will be set as the location of the error
11:32:41FromDiscord<Generic> for what you're doing specially there's a utility function in the macros module

14:50:27FromDiscord<hotdog> So if you want to use split to generate the output you said above, it will need to be something like `line.split("/")[0..2].join("/") & "/"`
14:51:02FromDiscord<hotdog> But there are better ways to do this, `std/strscans` is good for general parsing stuff, and there are uri specific parsers already

16:49:52FromDiscord<jan0809> not sure if its that easy on windows since it compile inside a virtual linux environment afaik
16:50:13FromDiscord<jan0809> i think to avoid the huge vs deps
16:50:28FromDiscord<jan0809> correct me if im wrong

16:57:09FromDiscord<jan0809> from the image? here https://github.com/dom96/choosenim
16:57:46FromDiscord<jan0809> atleast thats what i use to install nim
16:58:34FromDiscord<ZaRR> aaaa, I feel like there should be easier way. Let's wait what others say 🙂
16:59:19FromDiscord<jan0809> yeah true, i could totally be missinformed here
17:00:16FromDiscord<jan0809> but i would be interested in the answer aswell tcc sounds quite lightweight
17:05:50FromDiscord<ZaRR> https://nim-lang.org/faq.html↵at the bottom
17:12:44FromDiscord<auxym> afaik tcc should work on windows. you can do the config change as in the FAQ (either system wide config or project config) or pass `--cc:tcc` as a command line arg
17:13:50FromDiscord<auxym> tcc is small and fast, but does not optimize, so resulting code will be larger and slower compared to gcc/msvc/clang
17:17:49FromDiscord<jan0809> is tcc in any package manager (scoop chocolatey etc)
17:18:44FromDiscord<auxym> In reply to @jan0809 "dont remember right off": and msys2 is just a windows port of gcc and various related utils (make, binutils, etc). It's not a VM. Nim and msys2 works just fine on windows without WSL. Can also use MSVC in theory.
17:19:25FromDiscord<auxym> https://scoop.sh/#/apps?q=tcc&s=0&d=1&o=true
17:19:59FromDiscord<jan0809> yeah but its a way bigger download still on windows than inside wsl, and i have garbage internet connection so thats a huge difference for me lol
17:20:32FromDiscord<jan0809> but to be fair
17:20:45FromDiscord<jan0809> way way smaller then the vs compiler
17:21:20FromDiscord<auxym> trust me MSVC is worst 🙂 like 4 GB to get a working c/c++ toolchain with ms build tools 2022
17:21:42FromDiscord<jan0809> thats what i was talking about
17:21:46FromDiscord<auxym> just checked and msys2 download is 82 mb...
17:22:06FromDiscord<jan0809> ok thats not as big as i thought
17:22:26FromDiscord<auxym> but I mean if you want to play around with tcc go ahead, should work
17:22:42FromDiscord<jan0809> does nim work on alpine btw?
17:22:50FromDiscord<auxym> no idea
17:22:55FromDiscord<jan0809> or does it conflict with musl
17:23:41FromDiscord<auxym> no idea but: https://scripter.co/nim-deploying-static-binaries/
17:23:52FromDiscord<jan0809> chocolatey also seem to have tcc
17:26:28FromDiscord<ZaRR> I already configured ``cc:tcc`` in config file.↵Ofcourse I used msys2 before, but I wonder if possible to use Nim directly from Win.
17:26:57FromDiscord<jan0809> ah i remeber now i didnt had a problem msys2s size but i were afraid it could mess up devkitpro i think
17:27:58FromDiscord<Ekopalypse> @ZaRR - seems to work for me `nim r --cc:tcc --eval:"echo 1"`
17:28:04FromDiscord<Ekopalypse> on windows 10
17:28:07FromDiscord<auxym> In reply to @ZaRR "I already configured ``cc:tcc``": what about msys2 is not "directly on win"? As I said msys2 is a windows port of gcc and binuttils, etc, it's not any kind of VM
17:28:43FromDiscord<jan0809> it feels like that a bit bc in some form it offers a seperate shell just like wsl
17:29:10FromDiscord<auxym> MSVC also has its "shell" (Developer Command Prompt)
17:29:22FromDiscord<jan0809> oh dang thats true
17:29:33FromDiscord<auxym> they just add their stuff to PATH and maybe some env vars
17:29:50FromDiscord<jan0809> and it doesnt even expose the binarys to the normal powershell afaik
17:30:24FromDiscord<auxym> it might have an option to add its stuff to PATH during install but I cant remember
17:30:34FromDiscord<auxym> (global path)
17:30:36FromDiscord<jan0809> not sure neither
17:32:05FromDiscord<ZaRR> In reply to @Ekopalypse "<@516334337633943553> - seems to": still same error. I feel smth about path is wrong.
17:32:52FromDiscord<Ekopalypse> Can you call tcc -version
17:33:26FromDiscord<Ekopalypse> or `where tcc`
17:33:54FromDiscord<jan0809> is where windows which?
17:34:02FromDiscord<Ekopalypse> yes
17:34:08FromDiscord<Ekopalypse> 😄
17:34:08FromDiscord<jan0809> didnt knew that
17:34:20FromDiscord<Ekopalypse> is where which - still lol
17:34:31FromDiscord<ZaRR> both where/which not working for me.. weird
17:34:37FromDiscord<auxym> In reply to @ZaRR "still same error. I": what's the error? you never stated it
17:35:02FromDiscord<jan0809> did you reastart the terminal after adding to path?
17:35:04FromDiscord<ZaRR> in powershell 'where' seems working, but can't find tcc.↵I use cmd.
17:35:14FromDiscord<Ekopalypse> Me too
17:35:20FromDiscord<Ekopalypse> cmd user only
17:35:22FromDiscord<auxym> so tcc isnt on your path then?
17:35:45FromDiscord<auxym> `echo %PATH%` on cmd (or `echo $ENV:PATH` in posh)

18:30:15FromDiscord<mattrb> So 1.7.1 I guess
18:32:41FromDiscord<demotomohiro> Maybe it fails because sdl2 is only tested on latest stable version and not tested on latest devel branch.
18:33:45FromDiscord<mattrb> Heh well I mean that much was obvious. I just haven't had a chance to check which change to the compiler disallowed that syntax

19:07:37FromDiscord<Not Saucx> whats this?
19:29:47FromDiscord<auxym> you probably have a seq or array that is length 1, therefore the only valid index is 0 (0..0 range). 1 is no a valid index.
