00:02:35arkanoidyeah it is sad that I have to use my nim tools only on backend. Every time I try to build a windows tool I end up fighting with the AV and it looks like I am doing something nasty just to parse an xml
00:17:34FromDiscord<treeform> I primly develop on windows. I have 0 AV problems?
00:17:47FromDiscord<treeform> I think I disable all AV is its always bad for programming.
00:27:57FromDiscord<exithead> People actually program on windows? Wild.

00:41:21FromDiscord<j$> hey trying to use ffi, when importing structs do I have to declare all the fields?

01:13:41arkanoidI have to serialize and deserialize GeoJSON format. I'm trying to data map it with object variant, but the "coordinates" key (see example here https://en.wikipedia.org/wiki/GeoJSON) contains seq[int] for Point type and seq[seq[int]] for LineString and Polygon type. Nim does not support object variant with attributes with different types for same name. What's an idiomatic solution for this?
01:15:21FromDiscord<treeform> In reply to @arkanoid "I have to serialize": you could name them different things
01:15:34FromDiscord<treeform> you could have Point have seq[seq[int]] as well.
01:15:53arkanoidbut that's now what the standard wants
01:16:06arkanoids/now/not
01:17:54arkanoidI think I will have to work with generics
01:22:13FromDiscord<treeform> you have have a problem that prop can be any type
01:23:29FromDiscord<treeform> and Polygon is a seq of seq of 2 int
01:24:28*vicfred_ joined #nim
01:25:01arkanoidyou're right, polygon is seq[seq[seq[float]]]
01:25:12arkanoidwell, any idea?
01:25:30arkanoidI'm only thinking about GeoJson[T]
01:26:10FromDiscord<treeform> I got some thing like this:
01:26:11FromDiscord<treeform> https://play.nim-lang.org/#ix=3tjw
01:26:21FromDiscord<treeform> its not a nim friendly format
01:26:37FromDiscord<treeform> its schema is loose
01:27:04FromDiscord<treeform> I kept everything that is super dynamic as JsonNode

01:42:43FromDiscord<j$> In reply to @ElegantBeef "I dont know but": yeah there are some places that so you should not have to, but it was giving me some error, so for my use case ill just wrap fields in functions and call it a day
01:42:56FromDiscord<j$> (edit) "so" => "say"
02:01:07FromDiscord<ajusa> This might be a weird question but does os.walkDir not work for file paths that have an "!" in their filename? I just tested it on my machine and that seems to be the case
02:06:07arkanoidis there a function to sanitize file names so that they can be used in paths?
02:11:44FromDiscord<ElegantBeef> You mean remove the extension?
02:11:53FromDiscord<ElegantBeef> or get the name + extension?
02:15:10FromDiscord<carmysilna> I think they mean sanitize a tainted string so it’s safe to open that file name
02:15:37FromDiscord<ElegantBeef> Tainted strings are opt in and basically 0 people use them 😄
02:20:26FromDiscord<ElegantBeef> `splitFile` and `extractFileName` in `std/os` should help
02:47:08arkanoidI mean remove weird characters from file name, like ()!.'
02:48:58FromDiscord<ElegantBeef> You should be able to do `import std/[os, strutils];fileName.replace(invalidFileNameChars)`

03:42:57FromDiscord<Revenant> hiya, i'm trying to use NimScript as a build tool, replacing makefiles, basically, but can't figure it out how to get it to work because the documentation is quite sparse...
03:43:12FromDiscord<Revenant> i have this in `build.nims`
03:43:14FromDiscord<Bung> @haxscramper okay, get it.
03:43:26FromDiscord<Revenant> sent a code paste, see https://play.nim-lang.org/#ix=3tjS
03:43:59FromDiscord<Revenant> and this is how i'm trying to use it
03:44:15FromDiscord<Revenant> sent a code paste, see https://play.nim-lang.org/#ix=3tjT
03:44:37FromDiscord<Revenant> which doesn't actually execute the `build` task
03:47:05FromDiscord<Bung> task is defined by nimble
03:47:54FromDiscord<Revenant> no, it's defined by system
03:48:02FromDiscord<Revenant> it says it here https://nim-lang.github.io/Nim/nims.html
03:48:21FromDiscord<Revenant> "NimScript as a build tool" section
03:48:34FromDiscord<Revenant> but it doesn't show an example how to invoke the task in a nimscript file, that is my problem
03:51:28FromDiscord<Bung> hmm, havn't used it like this.
03:52:01FromDiscord<Revenant> okay, if i rename if to `config.nims`, then i can invoke `debug` with `nim debug`
03:52:45FromDiscord<Bung> so still works as a config file
03:53:27FromDiscord<Revenant> well... yeah... but the documentation is a bit misleading
03:53:39FromDiscord<Revenant> i thought you can just use tasks in any nimscript file
03:53:43FromDiscord<Bung> kinda , I agree
03:53:51FromDiscord<Revenant> but seems like just in the `config.nims` in the project root
03:54:25FromDiscord<Bung> more like config your build process
03:55:27FromDiscord<Revenant> yeah, it's all a bit confusing to be hones
03:55:28FromDiscord<Revenant> (edit) "hones" => "honest"
03:57:20FromDiscord<Bung> guess with nimble that parts does not need anymore.

04:28:39FromDiscord<ElegantBeef> does `code(res).int` work?
04:29:06FromDiscord<hamidb80> In reply to @ElegantBeef "does `code(res).int` work?": nope
04:29:15FromDiscord<hamidb80> In reply to @hamidb80 "the language server detect": but the compiler not
04:32:02FromDiscord<Hi02Hi> In reply to @Revenant "well... yeah... but the": as far as i can tell, nimscript tasks act on files with `file.nims` or with directories with `config.nims`
04:33:30FromDiscord<Revenant> In reply to @Hi02Hi "as far as i": this doesn't make much sense...
04:35:58FromDiscord<Hi02Hi> In reply to @Revenant "this doesn't make much": which part doesnt make sense? if you mean `file.nims`, then i mean if the project is in `main.nim`, then the nimscript file would be `main.nims`
04:36:52FromDiscord<Revenant> well, my original goal was to use NimScript as a substitute for makefiles
04:37:31FromDiscord<Revenant> maybe there are not even any Nim files involved
04:37:43FromDiscord<hamidb80> In reply to @ElegantBeef "does `code(res).int` work?": removing the argument type fixes the problem
04:37:47FromDiscord<Revenant> maybe i just want to write a "makefile" in NimScript for a C++ project, or whatever
04:38:43FromDiscord<Rika> wdym?
04:38:47FromDiscord<Rika> i mean to hamid
04:38:52FromDiscord<Hi02Hi> so ig use `config.nims` and use a bunch of `import os ... exec("build command")`
04:39:07FromDiscord<ElegantBeef> I just tested it hamidb and it worked
04:39:14FromDiscord<Hi02Hi> or is `import os` not needed
04:39:24FromDiscord<Rika> exec needs os
04:39:26FromDiscord<Rika> i believe
04:39:26FromDiscord<hamidb80> https://media.discordapp.net/attachments/371759389889003532/866177317009227786/unknown.png
04:39:42FromDiscord<Rika> what was the type before
04:39:48FromDiscord<hamidb80> Response
04:39:53FromDiscord<Rika> strange
04:39:56FromDiscord<ElegantBeef> Oh you're not exporting the frigging type
04:40:00FromDiscord<Revenant> my problem with using `config.nims` is that while it works, if i do `exec "nim ..."` from there, then the script gets executed a SECOND time when i exec the nim compiler from the script
04:40:01FromDiscord<ElegantBeef> (edit) "type" => "module"
04:40:02FromDiscord<Revenant> which sucks
04:40:02FromDiscord<Rika> what?
04:40:13FromDiscord<Revenant> how can i reliably parse extra command line params then?
04:40:13FromDiscord<Rika> beef what are you spouting
04:40:18FromDiscord<hamidb80> In reply to @ElegantBeef "Oh you're not exporting": ?!
04:41:09FromDiscord<ElegantBeef> I dont know how that macro works that those procs are declared in
04:41:27FromDiscord<hamidb80> addTestCov?
04:41:30FromDiscord<ElegantBeef> But i just assumed it was due to not exporting `httpclient` since it was a template
04:41:30FromDiscord<ElegantBeef> Yes
04:41:44FromDiscord<hamidb80> it just adds `cov` pragma to the procs
04:42:05FromDiscord<ElegantBeef> Well oddly enough `export httpclient` resolves the issue 😄
04:43:08FromDiscord<hamidb80> it works fine when i compile api.nim individually
04:43:32FromDiscord<hamidb80> but `nimble test` somehow break it
04:43:57FromDiscord<hamidb80> (edit) "break" => "breaks"
04:44:50FromDiscord<hamidb80> and something more strange:
04:45:11FromDiscord<hamidb80> i didn't import macroutils in `tests/tapi.nim`
04:46:05FromDiscord<hamidb80> but it somehow injected
04:46:10FromDiscord<hamidb80> and the last line: https://github.com/hamidb80/mycouch/blob/main/tests/tapi.nim#L67
04:46:14FromDiscord<hamidb80> doesn't work
04:47:32FromDiscord<hamidb80> In reply to @ElegantBeef "Pmunch emits some converters": .
04:47:49FromDiscord<hamidb80> (edit) "but it somehow ... injected" added "goy"
04:47:55FromDiscord<hamidb80> (edit) "goy" => "got"
04:47:58FromDiscord<Rika> In reply to @ElegantBeef "Well oddly enough `export": ah, this was a file being imported?
04:48:04FromDiscord<ElegantBeef> Yea
04:48:10FromDiscord<Rika> yeah that means code needs to be exposed to the importing module as well
04:48:17FromDiscord<Rika> so you need to export httpclient
04:48:19FromDiscord<ElegantBeef> I'm trying to find the logic in this code
04:48:37FromDiscord<Rika> you need to find the logic in your head first 😛
04:48:47FromDiscord<ElegantBeef> I mean i fixed the error
04:49:02FromDiscord<Rika> i dont actually know where you're looking at
04:49:09FromDiscord<ElegantBeef> https://github.com/hamidb80/mycouch/blob/main/src/mycouch/api.nim
04:49:23FromDiscord<ElegantBeef> guess i should've grabbed line 56
04:49:52FromDiscord<ElegantBeef> This is the first time i've seen someone use `using`
04:50:12FromDiscord<Rika> i use using, not often but ive used it
04:51:36FromDiscord<hamidb80> it's because i'm too lazy to write argument types
04:51:52FromDiscord<ElegantBeef> I know why people use it 😄
04:52:36FromDiscord<ElegantBeef> Ok so seems like this is a templates issue(bug?)
04:53:00FromDiscord<Rika> why?
04:53:34FromDiscord<hamidb80> removing type fixes the issue
04:53:37FromDiscord<ElegantBeef> I really should open this up in a properly setup editor to expand on it
04:53:48FromDiscord<hamidb80> In reply to @hamidb80 "": .
04:53:56FromDiscord<Rika> In reply to @hamidb80 "removing type fixes the": oh yeah i forgot about that

05:03:41FromDiscord<ElegantBeef> like i said replace it with `code(res)`
05:03:53FromDiscord<ElegantBeef> I mean it gets another compiler error unrelated
05:04:32FromDiscord<hamidb80> gives me same error
05:04:37FromDiscord<ElegantBeef> you didnt replace it in both spots
05:04:45FromDiscord<ElegantBeef> you use `res.code` twice
05:05:21FromDiscord<hamidb80> wow
05:05:35FromDiscord<hamidb80> fixes https://media.discordapp.net/attachments/371759389889003532/866183895871258624/unknown.png
05:05:38FromDiscord<hamidb80> the issue
05:05:47FromDiscord<ElegantBeef> Templates have some issues with the MCS when importing which can result in having to use C style calls
05:07:17FromDiscord<ElegantBeef> you can do `mixin code` in the first line to have it seem to work
05:07:23FromDiscord<ElegantBeef> But i dont know much about mixin/bind
05:07:53FromDiscord<ElegantBeef> Ah kinda makes sense what it does
05:09:52FromDiscord<hamidb80> works with mixin
05:10:04FromDiscord<hamidb80> https://media.discordapp.net/attachments/371759389889003532/866185022247272448/unknown.png
05:11:11FromDiscord<ElegantBeef> Almost like i tested it before hand 😄
05:16:16FromDiscord<hamidb80> do you know what are these errors? my code compiles but they exist https://media.discordapp.net/attachments/371759389889003532/866186588240085008/unknown.png
05:17:06FromDiscord<hamidb80> seems they dont give much information
05:17:26FromDiscord<ElegantBeef> It's something with your macros
05:31:33FromDiscord<hamidb80> it complains about `cov` ident https://media.discordapp.net/attachments/371759389889003532/866190433629765653/unknown.png
05:36:44FromDiscord<hamidb80> how can I tell to the compiler which `cov` i mean
05:37:05FromDiscord<hamidb80> `bindSym` seems not useful
06:24:43FromDiscord<Bung> there's something need improve, one that template/generic should be hint message, need to be configurable.
06:33:09FromDiscord<hamidb80> beef
06:33:15FromDiscord<hamidb80> i got confused

12:39:03FromDiscord<haxscramper> You can also implement custom (de) serialization hooks and so on
12:40:01FromDiscord<haxscramper> I removed dependency on nimble, but devel breaks hmisc, most likely due to this enum "fix"
12:40:24FromDiscord<haxscramper> But in the example I can use std libraries just fine (tables), so
12:41:18*max22- joined #nim
12:43:38FromDiscord<haxscramper> So you can use this example as a reference if you already have object unparsing implemented, though hnimast is probably the best you can get for that sort of thing, unless you want to spend as much time as I did
12:44:18FromDiscord<haxscramper> In reply to @haxscramper "I removed dependency on": I had distinct enum typedef and on devel I can't convert it to the underlying enum
12:54:26FromDiscord<haxscramper> Is it normal I'm getting insane number of strange type mismatch errors when switching to devel?
12:54:38FromDiscord<haxscramper> ``type mismatch: got <uint8> but expected one of: proc echo(x: varargs[typed, `$`]) ``
12:55:05FromDiscord<haxscramper> Also had to fix like 5+ pefectly normal procs that suddely failed to compile
12:55:30FromDiscord<haxscramper> Most of them were `Type1 | Type2` and I had to separate them into two procedures

13:00:41FromDiscord<haxscramper> And I had no implicit converters of course
13:05:05FromDiscord<haxscramper> Idk, maybe I just somehow managed to write all of the code incorrectly or something
13:08:17FromDiscord<haxscramper> In reply to @haxscramper "I had distinct enum": That one I at least figured out - now, for some reason you have to go through .int when converting distinct enum to the base type as well, which makes zero sense but anyway
13:09:15FromDiscord<haxscramper> But overall it seems like you are out of luck with hnimast on devel, @ElegantBeef , since I largely get completely random compilation errors for code that worked perfectly fine earlier
13:19:24FromDiscord<haxscramper> Also whatever fusion is installed by nimble & CI also fails with idk-why errors https://github.com/haxscramper/hmisc/runs/3097352353?check_suite_focus=true#step:5:24

14:33:53FromDiscord<generic linux user> just <> eh
14:47:24FromDiscord<jfmonty2> it appears that arrays indexed by enums are not bounds-checked? As in, if you cast an invalid value to the enum and use that to index the array, you can get a segfault.
14:47:48FromDiscord<jfmonty2> I'm guessing the official answer to this is "if you're casting types like that then you're taking your life into your own hands, the compiler can't help you"?
14:48:09FromDiscord<Rika> pretty much
14:48:51FromDiscord<Rika> i guess it would help if there was a runtime check for enum validity
14:49:07FromDiscord<deech> I'm using the `compile` pragma to build an object file, eg. `{.compile: "blah.cxx".}` but how do I pass the resulting `blah.cxx.o` to the linker? It ends up the the `~/.cache/nim/...` folder and simply doing `{.passL: "blah.cxx.o".}` doesn't find it.
14:49:19FromDiscord<jfmonty2> I mean there is, if you're using the regular conversions, but if you cast then all that goes out the window of course
14:49:30FromDiscord<Rika> well then there is the answer
14:49:39FromDiscord<jfmonty2> understandable but I will admit I was surprised since I was still intuitively expecting bounds checking to happen
14:50:06FromDiscord<Rika> https://nim-lang.org/docs/manual.html#implementation-specific-pragmas-link-pragma @deech
14:50:13FromDiscord<Rika> would this help
14:52:26FromDiscord<carmysilna> In reply to @ElegantBeef "Tainted strings are opt": Oh, that’s funny. It was one of the features that drew me to Nim
14:55:28FromDiscord<Rika> its being rethought i believe
14:55:34FromDiscord<Rika> effects system is the modern equivalent
14:55:51FromDiscord<deech> @Rika Same issue. The object file is in the `cache` directly but `g++` can't find it.
14:56:05FromDiscord<carmysilna> The effects system is pretty cool as well.
14:56:37FromDiscord<deech> I'll ask in internals as well.
14:56:41FromDiscord<Rika> no clue then
14:56:50FromDiscord<haxscramper> If it was possible to enforce conversion via procedure and forbid .string this could make sense, otherwise tainted mode does not enforce it enough
14:57:33FromDiscord<Rika> yes but how would taintedstring -> string work?
14:57:47FromDiscord<Rika> are we restricting people regards which procs they can use now or something
14:58:21FromDiscord<Rika> are we adding a pragma `io` or an effect `parseeffect` or whatever that marks the proc for handling io
14:58:36FromDiscord<Rika> (i guess ioeffect already handles io)
14:58:50FromDiscord<Rika> i guess an effect isnt the way to go either
14:58:57FromDiscord<Rika> since that bubbles up
14:59:48FromDiscord<haxscramper> Isn't it what tainted mode was for?↵(@Rika)
15:00:07FromDiscord<haxscramper> To make everyone write converters and validate data
15:00:35FromDiscord<carmysilna> Well, there’s also “parse, don’t validate” to consider
15:00:36FromDiscord<Rika> i meant more "restricting" as in "people cannot make procs that handle stuff, it must go through stdlib stuff to convert" or so
15:00:43FromDiscord<Rika> (ofc stupid idea)
15:02:28FromDiscord<carmysilna> Maybe all io functions in the stdlib could also accept Twitter strings as input and it would be assumed that they would be properly sanitized
15:04:10FromDiscord<Rika> twitter strings?
15:04:53FromDiscord<carmysilna> Sorry, autocorrect. Tainted strings
15:05:43FromDiscord<Rika> that doesnt seem sensible; i dont understand exactly
15:06:51FromDiscord<carmysilna> So readFile accepts TaintedString as wells as string, and properly sanitizes the tainted string so that it is safe to open as a file name
15:07:59FromDiscord<Rika> hmm
15:08:13FromDiscord<Rika> that sounds complex
15:08:21FromDiscord<Rika> every proc that takes in a string needs to have a counterpart then
15:08:40FromDiscord<konsumlamm> In reply to @carmysilna "Oh, that’s funny. It": it's deprecsted in devel now
15:08:47FromDiscord<haxscramper> No, `readFile` path has very little to do with tained strings
15:08:47FromDiscord<konsumlamm> (edit) "deprecsted" => "depreca5ed"
15:08:54FromDiscord<konsumlamm> (edit) "depreca5ed" => "deprecated"
15:08:54FromDiscord<haxscramper> It has everything to do with `AbsFile = distinct string`
15:09:06FromDiscord<haxscramper> What it returns can be tainted string
15:09:26FromDiscord<haxscramper> Data from the outside world is 'tainted' and should be validated
15:11:12FromDiscord<haxscramper> That is also true, more or less. Handling absolutely everything via simple `string` - absolute/relative directory/file/link paths, environment variable names etc. is not the best idea↵(@Rika)
15:11:20FromDiscord<haxscramper> at least because of the overloading
15:11:42FromDiscord<haxscramper> Otherwise we end up with `removeFile`, `removeDir` as if we didn't have static typing
15:12:27FromDiscord<haxscramper> Well, remove procs might benefit from being explicit, so `exists()` or `.ext()` is a better
15:12:33FromDiscord<haxscramper> example
15:18:04FromDiscord<carmysilna> In reply to @konsumlamm "it's deprecated in devel": Oh, okay, good to know

17:35:17FromDiscord<Ayy Lmao> I can't seem to capture `window` inside `windowProc` because it needs to be `stdcall`
17:37:44FromDiscord<Ayy Lmao> I basically just want to define my own draw procedure on a per window basis.
17:39:33FromDiscord<demotomohiro> Only closure proc can capture, other proc cannot.
17:39:58FromDiscord<haxscramper> IIRC you have to do `import ".."/[types, utill]`
17:40:19FromDiscord<Ayy Lmao> So am I basically forced to keep a table of all HWND : Window pairs and look up the Window in `windowProc` ?
17:40:52FromDiscord<haxscramper> If the code is does not have to be threadsave you can use `{.global.}` for captures
17:41:08FromDiscord<haxscramper> Copy captured variable to global, and make callback have `nimcall` or `stdcall`
17:41:13FromDiscord<haxscramper> But this is a hack
17:41:40FromDiscord<Ayy Lmao> In reply to @haxscramper "If the code is": Ideally I would like to stay away from something like that
17:42:04FromDiscord<haxscramper> Then you need to have lookup table somewhere else
17:42:37FromDiscord<Ayy Lmao> Alright, I figured that might be the case. It seems I was on the right track
17:42:47FromDiscord<haxscramper> Or you can store pair window + proc somehoa
17:43:55FromDiscord<Ayy Lmao> `windowProc` only gets a `HWND` passed in so that's all I have to go by to determine which window it is. I still need to look up the `Window` by its `HWND`
17:48:35FromDiscord<demotomohiro> Im usually use look up table like `Table[SomeId, ref Data]` when I use callback function in C library. Easy to detect use of id after freeing data.
17:49:40FromDiscord<demotomohiro> As long as id is never reused.
17:50:22FromDiscord<Ayy Lmao> In reply to @demotomohiro "Im usually use look": I will give it a try and see if I can get it working
17:55:53FromDiscord<demotomohiro> It seems this API can set pointer to user data on hWnd.↵https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-setwindowlongptrw
17:58:11FromDiscord<Ayy Lmao> In reply to @demotomohiro "It seems this API": Unfortunately I am limited as to what I can use from the win api. I am making an extension for Reaper which ports a small subset of the win api over to OSX/Linux. So if I want cross platform compatibility I have to stay within those constraints.
17:59:10FromDiscord<Ayy Lmao> They do seem to have `SetWindowLong` supported though
18:16:50FromDiscord<Ayy Lmao> Using `Window` as a `ref object` and creating a lookup table seems to work.
19:16:22FromDiscord<Stuffe> It seems you can't make a const out of a ref object or an object with a ref in it. The only work around I can think of for having a self referential const object is using a seq in the type, any other ideas?
19:21:27FromDiscord<haxscramper> `ref` is const is not supported yet https://github.com/nim-lang/Nim/pull/15528
19:22:03FromDiscord<haxscramper> And I don't think there are any workarounds, at least if you need `ref`

19:32:54FromDiscord<ache of head> the reason i'm asking this and not doing if something: echo a else: echo b is because i want to conditionally include something in a longer stdout.write

19:39:48FromDiscord<konsumlamm> huh

19:43:26FromDiscord<konsumlamm> In reply to @c1m5j "well, even something like": why would it? there is no value for the else case

19:45:34FromDiscord<Bung> @haxscramper interesting! how you pass around ref types and returns between them.
19:45:42FromDiscord<ynfle (ynfle)> Else, the compiler doesn't know the length
