01:04:07FromDiscord<ajusa> Hm, okay. I really like iface to be honest but the face that it isn't on Nimble is a little worrying for the future
01:04:17FromDiscord<ajusa> (edit) "future" => "future, like it's pre alpha"
01:08:29FromDiscord<ElegantBeef> I mean the API seems rather concrete so far so i wouldnt be overly concerned
01:09:17FromDiscord<ElegantBeef> You could always look at my devel variation using new concepts, but that's in an even worse state than iface 😄

01:10:54FromDiscord<ElegantBeef> I dont see why it matters if it's on nimble or not, since you can still depend upon it using a nimble package, the nice part about our decentralized package management
01:14:37FromDiscord<ajusa> Yeah, but even the author said that they don't like the API on the forums lol. I'll use it, worst comes to worst with a literal git commit URL in .nimble
01:15:00FromDiscord<ElegantBeef> Yea new concepts can empower a cooler version imo
01:15:29FromDiscord<ElegantBeef> Though i dont know about my method https://github.com/beef331/constructor/blob/master/tests/timplements.nim

02:01:48FromDiscord<Hi02Hi> is the capacity of a seq accessible?
02:03:32FromDiscord<Rika> not that i know of, why do you need it?
02:03:47FromDiscord<Rika> technically you can access it by changing the capacity to a known value
02:04:37FromDiscord<Hi02Hi> i was trying to see if setLen sets it exactly or not
02:05:30leorize[m]setLen set it exactly if the capacity is lower
02:05:43leorize[m]the current capacity is lower than what you specify*
02:05:51leorize[m]otherwise the capacity won't change
02:06:32FromDiscord<Hi02Hi> if it is greater, is the capacity changed exactly or with extra?
02:07:12leorize[m]exactly
02:07:22FromGitter<bung87> hi, am working on webframework , I have question about http parser, what if the client send wrong content-length to server?
02:07:27FromDiscord<Hi02Hi> ok thx
02:07:45leorize[m]@bung87 wdym wrong content-length?
02:09:00FromGitter<bung87> `proc remainLen(parser: MultipartParser): int {.inline.} = ⏎ parser.contentLength - parser.read`
02:10:07FromGitter<bung87> my parser depends on it , what if client send very big content -length , that just contains smaller body ?
02:10:22leorize[m]then it means you don't get enough data
02:10:29leorize[m]i believe the spec talks about this
02:12:21leorize[m]https://www.w3.org/Protocols/rfc2616/rfc2616-sec4.html#sec4.4
02:12:33leorize[m]spec said must be exactly the value or bust
02:13:43leorize[m]https://datatracker.ietf.org/doc/html/rfc7230#section-3.3.2
02:13:55leorize[m]^ read that since it's more up to date
02:17:04*arkurious quit (Quit: Leaving)
02:17:09FromGitter<bung87> ah ,when I can't get needed length just responds 400 , thanks!
02:31:23*noeontheend quit (Ping timeout: 246 seconds)
02:33:09FromDiscord<Casey.McMahon> for the compiler, if I use `--os:any` , do i need to include a `panicoverride.nim` file?
02:33:54FromDiscord<ElegantBeef> I dont recall if that's a requirement for `--os:standalone` or `--os:any`
02:35:06FromDiscord<Casey.McMahon> i noticed that it is mentioned in the 0.20 version of the compiler user guide, but the 1.5 version of the guide has it removed
02:35:23FromDiscord<ElegantBeef> I mean the compiler tells you when you need it
02:35:45FromDiscord<Casey.McMahon> https://nim-lang.org/0.20.0/nimc.html#nim-for-embedded-systems↵https://nim-lang.github.io/Nim/nimc.html#nim-for-embedded-systems
02:36:01FromDiscord<Casey.McMahon> so i guess not anymore?
02:37:23FromDiscord<ElegantBeef> Any does replace standalone so it seems yea not required
02:37:48FromDiscord<slymilano> Just wanted to share that we're going to start using Nim at https://papa.co 😃 We use Elixir for all of our services but we're going to use Nim to calculate some risk assessment scores for our members for our "Care Navigation" platform. Can't wait!
02:38:51FromDiscord<ElegantBeef> Nice, consider adding it to the list of "Companies that use Nim" on the wiki 😄
02:39:41FromDiscord<ElegantBeef> https://github.com/nim-lang/Nim/wiki/Organizations-using-Nim if curious where that is
02:40:25FromDiscord<slymilano> nice once we have a tangible implementation i'll add us there
02:40:40*azed quit (Quit: WeeChat 3.1)
02:43:33FromDiscord<Casey.McMahon> In reply to @ElegantBeef "Nice, consider adding it": I just realized your beef331 on github. I was asking that for the pico project.
02:44:09FromDiscord<ElegantBeef> I assumed that was you but didnt want to bring it up since i was 90% certain the panic override wasnt needed further
02:44:47FromDiscord<ElegantBeef> If you remove the nim file and the compiler doesnt complain it's fine 😄
02:45:19FromDiscord<Casey.McMahon> yeah the compiler didn't complain so I guess were all clear without it!
02:45:27*noeontheend joined #nim
02:45:49FromDiscord<ElegantBeef> And hopefully i didnt annoy you too much with my suggestions/view 😛
02:48:18FromDiscord<ElegantBeef> Seems we can also tick the file modification on windows by calling `copy /b FILENAME +,,` where `FILENAME` is the path to the cmakelist.txt
02:49:06FromDiscord<Casey.McMahon> no it all makes sense, although i looked into setting up a pico build environment on windows (i don't have windows so never was a problem) and it seems a little more complicated to get up and running then on linux. So i just mentioned some guides in the readme. Do you have a windows install?
02:49:36FromDiscord<ElegantBeef> I do have a windows OS installation, but i do not touch it for anything but gaming
02:51:41FromDiscord<Casey.McMahon> cool cool. Also are you okay with changing the hello world program to blink? or is there another reason for choosing that particular program?
02:52:01FromDiscord<Casey.McMahon> I guess not all board would have an led?
02:52:03FromDiscord<ElegantBeef> I named almost all the examples based off the pico-sdk
02:52:15FromDiscord<ElegantBeef> (edit) "I named almost all the examples based off the pico-sdk ... " added "examples"
02:52:41FromDiscord<ElegantBeef> It can be blink i guess, thought it was named hello_world LD
02:52:44FromDiscord<ElegantBeef> (edit) removed "LD"
02:53:19FromDiscord<Casey.McMahon> i guess not the hello world program itself (in the examples repo) , i just meant the program that comes with the template
02:54:12FromDiscord<ElegantBeef> Well the name doesnt really matter, so yea
02:54:56FromDiscord<ElegantBeef> It can be named "finglefangledringledrap.nim" for all i care
02:55:14FromDiscord<Rika> misread that as finger fangled death trap
02:59:28FromDiscord<ElegantBeef> So rika i changed the api drastically for my hseq, so now it's basically completely unrelated to it, i'm a great developer
03:00:02FromDiscord<Rika> nice
03:00:12FromDiscord<Rika> i dont actually have anything mean to say now
03:00:55FromDiscord<ElegantBeef> Lol, it now uses case statements and unpacks the variant value into an `it` so yea pretty similar but just meant for variants all together
03:01:20FromDiscord<Rika> right now im fixing some dude's SVD codegen for nim
03:02:28FromDiscord<ElegantBeef> svd codegen?
03:02:51FromDiscord<Rika> https://github.com/Birkemosen/svd2nim/
03:05:55FromDiscord<Rika> ngl i kinda wish we had more complex case objects
03:11:52FromDiscord<ElegantBeef> In what way?
03:13:02FromDiscord<Rika> like↵`when a.kind in {...}: ... elif a.kind == ...: ...` etc etc
03:13:22FromDiscord<ElegantBeef> Ah so what my library enables 😄
03:13:23FromDiscord<Rika> where one element in {...} is also the element in the elif branch
03:13:56FromDiscord<Rika> so more of `when a.kind in {x, ...}: ... elif a.kind == x: ...`
03:14:01FromDiscord<ElegantBeef> Although it only does it for types, similar logic could be expanded for a new case statement macro
03:14:07FromDiscord<Rika> ah, not elif, i guess its another when
03:14:26FromDiscord<Rika> `when a.kind in {x, ...}: ... ; when a.kind == x: ...`
03:15:01FromDiscord<Rika> i'd like to do this without another library though
03:15:44FromDiscord<ElegantBeef> Well i mean mine doesnt enable that, but yea casestmt macros are here though experimental
03:16:14FromDiscord<Rika> not really a case though is it? and case objects dont allow for duplicated fields across its branches
03:17:14FromDiscord<Rika> because the way that would need to be implemented would be like `case a.kind: of {...}: f1 f2 f3; of x: f1 f2 f3 f4 f5` which is illegal
03:17:43FromDiscord<ElegantBeef> How is that illegal?
03:17:48FromDiscord<Rika> have you tried it
03:20:27FromDiscord<ElegantBeef> would the dots be actual values or dots? 😄
03:22:15FromDiscord<Rika> values of course
03:22:24FromDiscord<Rika> enum values
03:22:50FromDiscord<Rika> f1... are fields with corresponding names and types (f1 == f1 everywhere)
03:23:28FromDiscord<ElegantBeef> Something like this could work https://play.nim-lang.org/#ix=3nwt
03:24:52FromDiscord<Rika> internet slow
03:25:12FromDiscord<Rika> im assuming its a proc thats called f1 and the different branches have different names for f1
03:25:28FromDiscord<Rika> no, f1 and others are fields in the object
03:26:13FromDiscord<ElegantBeef> Yea i'm too out of it to follow along today, so my bad ideas are even worse
03:26:26FromDiscord<Rika> lmao its fine
03:26:41FromDiscord<Rika> ive been slowly descending into madness because of the code im trying to fix

04:09:19FromGitter<bung87> hmm , could anyone give some web framework design rules? I feel trouble with exception, not sure whether raise or handled by framework
04:09:50FromGitter<bung87> eg. from user side `let j = await request.json()`
04:10:12FromDiscord<Rika> usually handled by framework, unless in a try block?
04:10:26FromGitter<bung87> my framework internal ⏎ ⏎ ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=60a8843245c2185a5ee1b270]
04:11:12FromGitter<bung87> there are lots of kinds exceptions , I have to decide one by one , that's bad to me
04:13:08FromGitter<bung87> another problem , in this case user can't custom how error responded, eg. they may want response a json with error message
04:13:53FromDiscord<Rika> you bubble the exception up past the programmer code, then handle it when its not caught by the programmer
04:16:17FromGitter<bung87> ```try: ⏎ await scorper.callback(req) ⏎ except: ⏎ discard``` [https://gitter.im/nim-lang/Nim?at=60a8859145c2185a5ee1b527]
04:16:34FromGitter<bung87> so I catch here cover all kinds of exception ?
04:17:04FromDiscord<Rika> pretty much yeah, i believe so
04:17:45FromDiscord<ElegantBeef> Yea an except like that will disregard all errors as if nothing happened
04:18:50FromGitter<bung87> ah ,seems good ! if end user catch I'll do nothing , if not I can response error msg with plain text
04:20:39FromDiscord<ElegantBeef> Feel like i should make a template entitled `doNotCrash` that takes a body and emits a try except 😄

04:31:39FromGitter<bung87> Thanks ! seems fine to me now.
04:33:04FromGitter<bung87> I may have own error json format respect to request accept header I think.
04:47:47FromDiscord<Casey.McMahon> In reply to @ElegantBeef "Seems we can also": is all the procs in the nimscipt module platform independent? could I just use this proc instead? ↵https://nim-lang.org/docs/nimscript.html#cpFile%2Cstring%2Cstring
04:48:23FromDiscord<ElegantBeef> Yea they should be platform independant
04:48:43FromDiscord<Casey.McMahon> cool
04:49:05FromDiscord<ElegantBeef> I've got to be the worst person to maintain the pico stuff since i dont have much reason to use the pico 😄
04:50:17FromDiscord<Casey.McMahon> well I kinda want to learn how to make bindings, so i guess this might be a good project to learn? I don't know how complex the SDK truly is...
04:50:36FromDiscord<ElegantBeef> the reason for the touch is to tick the time of file creation, idk if any of the procedures will do that
04:50:51FromDiscord<ElegantBeef> The pico-sdk is relatively simple, tinyusb is rather annoyingly complex
04:51:53FromDiscord<Casey.McMahon> haha i forgot to init the submodule the other day, and was running into cryptic error messages down the line that did not point to tinyusb as the cause
04:52:19FromDiscord<ElegantBeef> I'm sure you've looked at the actual stdlib so it should be rather easy wrap it
04:55:45*vicfred quit (Ping timeout: 260 seconds)
04:56:12FromDiscord<ElegantBeef> my attempt was to make it a more idiomatic Nim library but you could always just try c2nim with it if you wanted a usable version 😄
04:57:14FromDiscord<Casey.McMahon> I'm a fan of idiomatic, it's all about the learning process haha.
04:58:33FromDiscord<ElegantBeef> One of the big detractors is i dont really have the knowledge/physical parts to test the code
04:59:33FromDiscord<Casey.McMahon> my biggest project so far has been trying to create an eeprom programmer. If I had choosen arduino i wouldn't have even had to do anything, would have been done a long time ago. BUT i decided to go with a new microcontroller (limited libraries) and a niche programming language haha.
04:59:39FromDiscord<Casey.McMahon> https://media.discordapp.net/attachments/371759389889003532/845526291490013184/IMG_20210427_142558_1.jpg
05:00:12FromDiscord<ElegantBeef> Shit that's possible with the small amount of code i wrapped?
05:00:36FromDiscord<Casey.McMahon> thus far...
05:01:11FromDiscord<Casey.McMahon> i had to write a custom shiftout module
05:01:16FromDiscord<Casey.McMahon> kinda like this one: https://www.arduino.cc/reference/en/language/functions/advanced-io/shiftout/
05:01:38FromDiscord<Casey.McMahon> the led's represent the EEPROM in this case haha
05:02:42FromDiscord<ElegantBeef> Wonder if that is in the pico-sdk and i just didnt wrap it
05:03:06FromDiscord<Casey.McMahon> i did some hard googling, couldn't find it
05:04:47FromDiscord<ElegantBeef> Anywho if you do find some C code you want to use but need to wrap it i can help with it, more fearful of the inability to test if the code is working properly
05:05:03FromDiscord<ElegantBeef> I do mean to get back to tinyusb and get it working but it's an annoying api
05:06:52FromDiscord<Casey.McMahon> one day haha, no rush.
05:12:36FromDiscord<Casey.McMahon> do you know how i would place a variable inside a exec command? like,↵`exec("cmake {var} ..")`
05:12:53FromDiscord<Casey.McMahon> guess i could make the string beforehand...
05:13:05FromDiscord<ElegantBeef> `import std/strformat` `exec(fmt"cmake {var} ..")`
05:13:19FromDiscord<Casey.McMahon> thx!

12:41:43PMunchHmm, is there a way to expand a non RootObj in Nim?
12:42:26PMunchLike have one type with some fields, and then have another type which expands the first type with more fields
12:42:30PMunchWithout having to re-type all the fields
12:43:01PMunchThis is for micro-controller stuff, so I don't want the overhead of RootObj..
12:43:30PMunchHmm, I guess I could just have the first type as a field..
12:52:50PMunchHmm, any way to make this work? `proc setupTransmit*[P: static[Pin]](pin: P): ManchesterTxOnly[P]`
12:53:29PMunchThe goal is to be able to do `var transmitter = txPin.setupTransmit()` where txPin is a static Pin

14:12:19FromDiscord<mlokis> Is nim compiling packages that depend on same module concurrently?
14:12:33FromDiscord<mlokis> (edit) "Is nim compiling packages that depend on same ... module" added "common"
14:12:41FromDiscord<mlokis> (edit) "packages" => "modules"
14:17:56FromDiscord<haxscramper> I think nim compilation is single-threaded regardless of the module dependency graph
14:18:25FromDiscord<mlokis> so nim compiles on single thread
14:18:44FromDiscord<mlokis> it makes sense when we have static blocks
14:19:11FromDiscord<mlokis> well then i dont have to worry about race conditions in static blocks
14:20:18FromDiscord<mlokis> though it would be logical to compile modules with no relations concurently
14:22:18FromDiscord<haxscramper> I don't think it makes sense really - IC will remove the need to recompile unchanged modules, and writing multhithreaded compiler is probably very difficuly
14:22:52FromDiscord<mlokis> In reply to @haxscramper "I don't think it": you have a point there
14:47:51FromDiscord<zetashift> erhm, say I have a uint32, how would I select/split it and get the 4 bytes separetly returned?

17:54:44FromDiscord<mlokis> Why does all serious libraries use object oriented staff? I was searching for a image loading library but they all use inheritance with ref objects. Is that some kind of a good practice? Or is there some good reason to do so.
18:09:07FromDiscord<dom96> which serious libraries did you check?
18:09:18FromDiscord<dom96> Nim tends to discourage OO
18:21:22FromDiscord<mlokis> In reply to @dom96 "which serious libraries did": nimPNG and nimage
18:21:34FromDiscord<dom96> well, that's not a big sample size 🙂
18:22:19FromDiscord<mlokis> but the there is also some opengl abstraction that objectifies everything
18:22:27FromDiscord<mlokis> i have OO
18:22:34FromDiscord<mlokis> (edit) "have" => "hate"
18:22:54FromDiscord<krab4t> any auto-completion support for sublime 4 in nimlime? 🙂 it doesnt work here
18:24:23FromDiscord<mlokis> Why does the nim have OO in first place? Some backwards compatibility issue? I would match rather have interfaces instead
18:24:27FromDiscord<ElegantBeef> It highly depends on what they're doing, pointer procs can also be used if you arent adding logic in children
18:25:49FromDiscord<mlokis> (edit) "match" => "much"
18:34:25FromDiscord<exelotl> nimPNG is pretty bewildering tbh

19:26:15FromDiscord<treeform> In reply to @mlokis "Why does all serious": Pixie can load images and does not use OOP.
19:27:02FromDiscord<treeform> Pixie is much faster then nimPNG at loading pngs.
19:28:05FromDiscord<treeform> Pixie's PNG loading is just 500 lines in a single nim file, hopefully not that hard to understand: https://github.com/treeform/pixie/blob/master/src/pixie/fileformats/png.nim
19:28:24FromDiscord<treeform> it uses the zippy library though (which is also very fast)
19:31:17FromDiscord<treeform> Pixie also can do a ton of other things that you would want to do with images after you load them: https://github.com/treeform/pixie
19:33:00FromDiscord<exelotl> oh that looks very nice
19:38:39FromDiscord<geekrelief> In reply to @exelotl "huh, no you can": You're right. I forgot about `staticRead` I came across that `importc` issue before, so I was looking to fix that issue instead.
19:40:07FromDiscord<exelotl> it's very cool to see that compile time FFI is possible though, I didn't know about it
20:25:39FromDiscord<mlokis> In reply to @treeform "Pixie can load images": nice, i ll probably just paste that code and modify it little, all i need is image loading
20:38:18FromDiscord<treeform> In reply to @mlokis "nice, i ll probably": Sounds good, I think only half deal with image reading (the rest is image writing)

21:39:25FromDiscord<brainproxy> so I found a workaround: if in module B I create a constant by the same name as the constant table exported by module A, with A's table assigned to the constant in B, then there's no compiler error and the compiled executable runs correctly

22:05:33FromDiscord<Casey.McMahon> currently for a project template we are asking the user to find their `nimbase.h` and place it next to some compiled C code. Rather than doing that, is it sufficient to check the user's Nim version and grab the appropriate `nimbase.h` file from the Nim github repo (like here: https://github.com/nim-lang/Nim/blob/version-1-4/lib/nimbase.h). ↵↵I see that every major release has it's own branch. But do breaking changes within the `
22:10:29FromDiscord<ElegantBeef> casey we can just query the nim version on creation and if they have choosenim if so automatically copy that version's nimbase.h into the directory

23:08:57FromDiscord<Rika> ?
23:09:02FromDiscord<Rika> whats the issue there
23:09:24FromDiscord<ElegantBeef> i presently dont have a way to easily capture all args after the present one
23:09:50FromDiscord<Rika> ...why not
23:09:54FromDiscord<ElegantBeef> Shouldnt be too difficult just using an ordered table instead of a table to store the commands
23:09:57FromDiscord<ElegantBeef> I never got around to it
23:10:24FromDiscord<Rika> wait why are you using a table? afaik both a table and a seq are used for stuff like these
23:11:30FromDiscord<ElegantBeef> So i can generate a LUT for parsing the commands
23:11:36FromDiscord<ElegantBeef> Like i said it needs work 😄
23:11:58FromDiscord<Rika> i might just fork this and put my ideas into it then just call me if you want to steal something xd

23:12:59FromDiscord<Rika> im still debating whether if i want to ngl

23:13:35FromDiscord<ElegantBeef> Yea i mean it was just created after seeing a comment timothee left about nimgrep docs, and i felt like "hey this isnt too hard to make"
23:14:27FromDiscord<ElegantBeef> Got the basis down then started dog fooding a small choosenim alternative with it, then killed it and threw it in a ditch
23:15:17leorize[m]reminds me of nim-argparse
23:15:44FromDiscord<ElegantBeef> Seems similar
23:15:57FromDiscord<Rika> didnt know you were fine with killing dogs
23:17:08FromDiscord<Rika> okay so maybe i wont work on it, i thought it was another kind of tool
23:17:27FromDiscord<Rika> ive not much use of a cli tool creator
23:17:41FromDiscord<ElegantBeef> Ah
23:20:11FromDiscord<ElegantBeef> It's actually very similar to arg-parse, might as well kill off commander 😄
23:22:41FromDiscord<Rika> lol
23:23:23FromDiscord<ElegantBeef> Now for someone to point out there is a better implementation of all my libraries
23:24:04FromDiscord<Rika> "btw i made a library thats newer than urs but better"
23:25:19FromDiscord<ElegantBeef> Although it doesnt seem argparse lets you run code on successful parsing of arguments, so you have to manually check it after calling parse
23:28:11FromDiscord<ElegantBeef> I still need a name for my ex hseq library, thinking `Varbear` but that only makes sense if you pronounce `var` like in variant

23:29:19FromDiscord<ajusa> sent a code paste, see https://play.nim-lang.org/#ix=3nAu
23:29:39FromDiscord<ajusa> specifically the multiple definition part for the linker - how do I even start to figure out why that's happening
23:29:54FromDiscord<ElegantBeef> have you declared anything named `tab`?
23:30:29FromDiscord<ajusa> nope
23:30:55FromDiscord<ajusa> but `iface` does declare a global called `tab` in its source code
23:31:19FromDiscord<ElegantBeef> Cant reason much outside that 😄
23:32:03FromDiscord<ajusa> am I somehow importing it twice? I don't think that's even possible though
23:32:15FromDiscord<ElegantBeef> Even if you did that shouldnt be an issue
23:34:29saemShould it be possible to do something equivalent to `type Foo[T] = when T is string: int else: T`?
23:35:04saemRather, I'd like to and how might I go about doing something like that because the above doesn't work.
23:37:10saemI have distinct NimNode types, and I want a Maybe[T], that specializes to a distinct typedef based on T. This way I can create procs that operate on various sub-groups of NimNodes in a type safe manner.
23:37:43FromDiscord<ajusa> In reply to @ElegantBeef "Even if you did": so when I changed how I imported the module the problem went away... no clue how I managed to do that though. I think it may have been some weird circular import that caused the linker to fail? This was running in a when main module thing, so maybe that's why Nim didn't catch it?
23:38:39FromDiscord<Rika> nim should have caught it before the linker did even in a when branch
23:39:54FromDiscord<ElegantBeef> Saem if you wrap the when in `()` it compiles but doesnt do what you want, presently when statements in generics always evaluates to the else branch
23:40:03FromDiscord<ajusa> In reply to @Rika "nim should have caught": Hm, I'll try making a MWE then
23:40:19FromDiscord<ElegantBeef> https://play.nim-lang.org/#ix=3nAw example of it "working"
23:40:50FromDiscord<ElegantBeef> https://github.com/nim-lang/Nim/issues/17840
23:40:50FromDiscord<ajusa> in general, are most things that cause `ld` to fail or `gcc` considered Nim bugs? Unless there is some emit or unsafe shenanigans going on
23:41:41saemhmm, I guess the other thing to consider is that a single field object is equivalent to the field itself in C/C++ IIRC. So maybe I can wrap it under an `object` and call it good?
23:42:01FromDiscord<dom96> In reply to @slymilano "<@!132595483838251008> I cant post": ahh, sorry about that. I changed the permissions, can you give it another try? 🙂
23:42:33FromDiscord<ElegantBeef> Yea an object with a single field is the same as an distinct alias internally afaik
23:43:37FromDiscord<Rika> it is?
23:44:01FromDiscord<ElegantBeef> Well it takes the same size as the field of the first object, and it doesnt work with any procedures
23:44:06FromDiscord<ElegantBeef> I dont mean in Nim i mean in C
23:44:17FromDiscord<Rika> xd
23:44:41FromDiscord<ElegantBeef> Anywho as you know saem generics are.... special
23:45:58FromDiscord<ElegantBeef> Anyone want to mark that issue i linked above as a `generics` issue, thanks
23:48:20saemso something like this should work I think... `type Foo[T] = distinct object when T is SpecialNode: n: SpecialNode elif T is NimNode: n : T else: {.error: "nope".}`
23:48:40FromDiscord<ElegantBeef> Except it'll only error
23:49:02saemWait... doesn't that cause issue for Option?
23:49:12saemhttps://github.com/nim-lang/Nim/blob/version-1-4/lib/pure/options.nim#L69
23:49:28FromDiscord<ElegantBeef> I misread the code as a single line
23:49:45FromDiscord<Rika> bruh
23:49:46FromDiscord<ElegantBeef> Wait why the fuck does that work, but not in a single line
23:49:47saemyeah, sorry
23:50:20FromDiscord<ElegantBeef> Excuse me whilst i go abuse myself to resolve the first thing you wanted not working
23:50:38saemhehe
23:51:13FromDiscord<ElegantBeef> For some reason seming when statements for types just defaults to the last tree
23:51:31FromDiscord<ElegantBeef> So it's probably just something messing up the indexing there or actual behaviour
23:52:02FromDiscord<ElegantBeef> Also saem your extension works lovely with onivim2 😄
23:52:59saemIn fairness the RHS doesn't provide a type but rather a type expression... so maybe this is all sorta silly.
23:53:22saemProbably should be a `where`, because other languages, future direction notes, and all that.
23:53:43saemElegantBeef: glad to hear that it works well with it.
23:54:04FromDiscord<ElegantBeef> Yea i suppose it's an expression that's sem'd without T context
23:54:30FromDiscord<ElegantBeef> As such it goes to else
23:54:47saemYeah, when is a compile time expression, but not really a type time expression which is what one would want and that's a whole thing.
23:55:06FromDiscord<ElegantBeef> We'll you've saved my self harm, thanks
23:55:08saemBut that gets all muddy.
23:55:21saemoh yeah, how so?
23:55:45FromDiscord<ElegantBeef> You made me talk more about it and realize it's working "properly", so it'd require a large amount of compiler work to "fix"
23:56:16saemAh, yeah that.
23:56:32FromDiscord<ElegantBeef> I'm a numpty i cant even do a small amount of compiler work 😄
23:56:52saemThere is nothing small about it in the way things are.
23:57:01saemThere is a reason why I'm poking at this AST stuff.
23:57:04FromDiscord<ElegantBeef> have you continued writing that new generics/type system proposal?
23:57:34saemNo, I burned out a bit lately so not trying to do anything that I feel even the slightest amount of resistance doing.
23:58:32FromDiscord<ElegantBeef> Yea i've been wanting to work on a game but instead made 2 libraries, so i'm uhh a great game dev 😄
