01:23:27FromDiscord<Elegantbeef> `cstring myExpression`
01:24:20FromDiscord<Forest> But I'm passing it to JS
01:24:30FromDiscord<Elegantbeef> cstring is "compatible string"
01:24:36FromDiscord<Elegantbeef> You can ignore it on JS afaik
01:25:01FromDiscord<Forest> So the warning doesn't affect JS then?
01:25:07FromDiscord<Forest> And won't in the future?
01:25:29FromDiscord<Elegantbeef> Like i said you can just convert it manually and the warning goes way
01:25:51FromDiscord<Elegantbeef> so you probably should convert it anyway
01:26:07FromDiscord<Elegantbeef> The implicit conversion is a possible unsafe operation which is why that warning exists
01:26:17FromDiscord<Elegantbeef> possible unsafe operation on C/C++\
01:26:26FromDiscord<Forest> But how would i pass it to JS then without using `importjs`?
01:26:38FromDiscord<Elegantbeef> `cstring`
01:26:42FromDiscord<Forest> Since i have to use JS's `new`
01:26:49FromDiscord<Forest> In reply to @Elegantbeef "`cstring`": I don't understand
01:26:56FromDiscord<Elegantbeef> just do `cstring(expression)`
01:27:05FromDiscord<Elegantbeef> where expression is the template or macro you're using
01:27:49FromDiscord<Forest> `proc newFile(parent: JsObject, child: cstring) {.importjs: "new File(@)".}`
01:28:10FromDiscord<Elegantbeef> now where do you call that
01:28:19FromDiscord<Forest> Wait
01:28:25FromDiscord<Forest> Ohhhhh i understand what you mean now

02:36:33FromDiscord<Elegantbeef> an 110 line function with no comments, scary
02:38:35FromDiscord<deech> What is the difference between a HSlice & a tuple?
02:39:44FromDiscord<Elegantbeef> Hslice is an easier type to abstract over imo
02:40:00FromDiscord<Elegantbeef> It's also distinct
02:40:13FromDiscord<Elegantbeef> Not all `(int, int)`s are valid slices
02:42:07FromDiscord<Elegantbeef> Atleast i interpreted it as "Why not use a tuple for slices instead"
02:42:50FromDiscord<deech> Yes that's what I meant.
02:43:42FromDiscord<huantian> In reply to @Elegantbeef "an 110 line function": that's a lot of indentation
02:44:39FromDiscord<Elegantbeef> i'm a bit biased cause i find tuples only useful for return types/unpacking
02:44:47FromDiscord<Elegantbeef> Pretty everywhere else i much prefer static typing
02:46:03FromDiscord<Elegantbeef> `type HSlice[X, Y] = tuple[a: X, b: Y]` is not so weakly typed 😛
02:46:10FromDiscord<Elegantbeef> i guess i should say strong typing
02:48:29FromDiscord<deech> I get why Slice is useful but looking over the codebase the only use of HSlice I'm seeing is [int, BackwardsIndex]. Are there any other compelling use cases?
02:48:48FromDiscord<Elegantbeef> `[a..b]`
02:49:51FromDiscord<Elegantbeef> It's a strongly typed heterogeneous pair of values, it's useful whenever you need a runtime range
02:50:11FromDiscord<Elegantbeef> It's primary use is indexing but i'm sure there are other uses

02:52:49FromDiscord<Elegantbeef> You can do `someFloat in 0d..30d` or similar for your types that implement the operators needed
02:54:58FromDiscord<Elegantbeef> "In this episode of beefs ramblings cause someone to lose conversational interest" 😛
02:59:35FromDiscord<deech> Haven't lost interest just looking over the codebase for uses of HSlice where the types aren't Ordinal.
03:00:28FromDiscord<Elegantbeef> Distincts would be one place
03:00:57FromDiscord<Elegantbeef> I guess that is ordinal 😀
03:01:31FromDiscord<Elegantbeef> User defined numeric types that are not Ordinal based would be something
03:01:39FromDiscord<Elegantbeef> 128bit integers/floats for instance
03:02:42FromDiscord<deech> Why are they not ordinal?
03:03:33FromDiscord<Elegantbeef> Cause ordinal is a hard coded typeclasss
03:06:19FromDiscord<deech> I see. Well looking over `system.nim` it looks like the HSlice is constrained by Ordinal, so even if the user had a non ordinal type they wouldn't be able to use any of that. I guess they could overload `[]` and `[]=` etc.
03:06:56FromDiscord<deech> (edit) "Ordinal," => "Ordinal for useful indexing functions,"

03:14:10*jmdaemon joined #nim
03:14:13FromDiscord<deech> Unless I'm missing something there's not much I can do except access `a` and `b`. Even `len` requires Ordinals.
03:14:54FromDiscord<Elegantbeef> That's up to a user implementation you could in theory make `a..b` for string disallow anything outside of that
03:15:31FromDiscord<Rika> Length could mean anything for non ordinals and it’s up to the implementer what it would mean
03:17:14FromDiscord<kiell> whats the difference between object and rootobj?
03:17:15FromDiscord<deech> Yep, so I guess I'd need to redefine all those. I guess custom ranges could be useful.
03:17:33FromDiscord<deech> In any case, going to bed. Thanks!
03:17:34FromDiscord<Elegantbeef> Root object is the root for inheritance↵(@kiell)
03:19:03FromDiscord<kiell> so if i dont plan to use an object for inheritance then rootobj isnt required?
03:19:34FromDiscord<Elegantbeef> Yep
03:19:38FromDiscord<kiell> im just confused why ppl do `type obj = ref object` vs `type obj = ref object of RootObj`
03:19:41FromDiscord<kiell> ok
03:22:33FromDiscord<deech> Boy using negative ranges to slice seqs should be caught at compile time although it would be pretty cool if `@[1,2,3][^1..0]` reversed the seq. https://play.nim-lang.org/#ix=3Qff
03:23:03FromDiscord<Elegantbeef> They want inheritance kiell or dont know what they're doing
03:25:09FromDiscord<Elegantbeef> Well you could do the negative ranges using `static HSlice`

07:32:49FromDiscord<tosh [uniware]> can u explain what this kinda does cuz im lowk confused
07:33:03FromDiscord<ShalokShalom> In reply to @Elegantbeef "one of them returns": do you mean me?
07:33:22FromDiscord<Elegantbeef> we declare `aProccess` of an array with a size of `1024` and elements of `Dword`
07:33:43FromDiscord<Elegantbeef> We then declare `cbNeeded` and `cProcesses` as DWord and `i` as uint 😛
07:34:22NimEventerNew thread by Mardiyah: Correct way have for-loop iteration up to number of only initialized array elements, see https://forum.nim-lang.org/t/8936
07:34:22FromDiscord<tosh [uniware]> is `aProcess` supposed to be `aProcesses` 🤔
07:34:49FromDiscord<Elegantbeef> Now the fun part is we make an if statement calling `enumerateProcess` with the address of the first element of the array since it wants the first element of a collection, then the size of the array, and the count return
07:34:54FromDiscord<Elegantbeef> Yea it should be

07:44:38FromDiscord<Elegantbeef> The important part is going to be the `LPWSTR` so now we get to figure out how that works
07:47:07FromDiscord<Elegantbeef> The issue is less Nim syntax imo, and more lack of procedure definitions

09:50:16FromDiscord<Waldecir Santos> Is it possible to have `"named"` varargs I want to mimic python `kwargs`.
09:55:15FromDiscord<Elegantbeef> what's kwargs do again?
09:55:43FromDiscord<Waldecir Santos> kwargs is a dict inside the "proc"
09:55:54FromDiscord<Elegantbeef> Ah then like i said last time use `tuple`
09:56:59FromDiscord<Waldecir Santos> Hmm let me check.
09:57:48FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=3Qgx
09:58:11FromDiscord<Elegantbeef> You can write a macro to do the introspection better, or use a concept
09:59:28FromDiscord<Elegantbeef> For the concept variant
09:59:30FromDiscord<Elegantbeef> sent a code paste, see https://paste.rs/JpN
09:59:50FromDiscord<Waldecir Santos> Yeah I'm trying to avoid the double `((` this looks terrible.
10:00:18FromDiscord<Waldecir Santos> Wow this is the first time I see `concept` awesome
10:00:49FromDiscord<Elegantbeef> I dont get the point of kwargs
10:01:09FromDiscord<Elegantbeef> Just take an optional and or defaults
10:01:20FromDiscord<Waldecir Santos> I need to do some magic to convert it to SQL queries
10:01:52FromDiscord<Waldecir Santos> Like django thoes, e.g: `Entry.objects.filter(pub_dateyear=2006)`
10:02:17FromDiscord<Waldecir Santos> or `Entry.objects.filter(headlinestartswith="What")`
10:02:32FromDiscord<Elegantbeef> Sure you dont need kwargs just make `filter` a macro
10:02:50FromDiscord<Rika> You can get nicer syntax with a macro, even
10:03:18FromDiscord<Waldecir Santos> Sure but this will not work at runtime right ?
10:03:58FromDiscord<Elegantbeef> What do you mean?
10:04:26FromDiscord<Rika> You need your “kwargs” to be runtime modifiable!
10:04:28FromDiscord<Rika> ?
10:04:45FromDiscord<Waldecir Santos> I mean these args can be defined at run time, they cannot be determined at compile time
10:04:50FromDiscord<Waldecir Santos> Yes @Rika
10:05:04FromDiscord<Rika> Runtime defined ain’t runtime modified
10:05:16FromDiscord<Rika> Anyway a macro will do fine with something like that
10:05:55*jjido quit (Quit: My MacBook Air has gone to sleep. ZZZzzz…)
10:06:06FromDiscord<Rika> In reply to @Rika "Runtime defined ain’t runtime": Maybe this is just me being physically tired today though I don’t know
10:06:13FromDiscord<Elegantbeef> If i understood what was desired i'd say what to do but i'm just lost
10:06:14FromDiscord<Rika> But a macro should suffice
10:07:17FromDiscord<Elegantbeef> No waldecir dont talk about django, that doesnt help
10:08:12FromDiscord<Waldecir Santos> @ElegantBeef I need to access a list of params and it's values inside a proc and this list can be anything it will be "generated" at runtime, maybe this is a better explanation
10:08:52FromDiscord<Elegantbeef> so a `Table[string, string]` 😀
10:09:12FromDiscord<Waldecir Santos> Tuple is perfect, but I have the `((` `))` and this looks aweful
10:09:46FromDiscord<Elegantbeef> You could always make a macro for the call then convert it into a tuple and call the proper thing
10:10:10FromDiscord<Waldecir Santos> Yeah I'll play with it, you both helped a lot.
10:10:14FromDiscord<Waldecir Santos> Thank you
10:10:53FromDiscord<Elegantbeef> I've never dealt with this stuff so you asking these questions just makes me question my sanity

10:12:52FromDiscord<Waldecir Santos> In reply to @Elegantbeef ""I dont understand why": Same but my goal is just to mimic some parts or django to help web dev in nim, this is maybe not possible, but I'm learning Nim in the process so it worth ! 😄
10:13:08FromDiscord<Elegantbeef> It's 100% possible
10:13:19FromDiscord<Elegantbeef> You just have to know what you need explicitly 😛
10:13:47FromDiscord<Waldecir Santos> Right, that is my problem right now, too much unknowns from my side
10:15:15vilhelmbergsoeHi there, i have a question regarding where, in the development space, nim fits in. Is it more comparable to a language like c or rust in that it is a systems language? or is it also used in networking like go? Might seem like a stupid question, but i'm just trying to get a quick idea of nim :)
10:15:35FromDiscord<Elegantbeef> It's used all over the plcae
10:15:37FromDiscord<Elegantbeef> place\
10:15:53FromDiscord<Elegantbeef> It can be used for everything without much hassle imo
10:16:01FromDiscord<Rika> I would say it leans heavier to system than networking.
10:16:29FromDiscord<Rika> But it is applicable in a lot of areas, just needs work
10:17:16FromDiscord<Elegantbeef> Yea there are some issue with concurrency and parallelism presently i think, but weave/taskpools help there
10:21:43vilhelmbergsoeAlright nice! and thanks :)

14:28:25PMunchThanks for the kind words, glad you enjoy my work :)
14:29:57FromDiscord<lpha3ch0> Unfortunately, while this looks great in the Linux terminal, the symbols are ugly in the Windows terminal.
14:31:25FromDiscord<lpha3ch0> That's just Windows displaying unicode thing. I printed the same symbols in the Windows terminal without using termstyle, only the unicode and it's ugly. But what else should we expect from Windows. LoL
14:35:10PMunchYeah the Windows terminal isn't great..
14:35:18PMunchPowershell is apparently a bit better though
14:35:58PMunchBut termstyle is really only meant for terminals which are compatible with ANSI colours, so the windows terminal is already out I believe
14:36:56FromDiscord<Rika> are we talking about the new windows terminal or the old command prompt

14:54:19PMunch@Schelz, not quite sure what you mean
14:55:59PMunchYou technically don't "link" C++ files, you "link" a dynamic or static library, and at that point it doesn't matter much which language it was written in
14:56:45PMunchBut you can `importcpp` things from a header in Nim and build with the C++ sources?

17:12:10FromDiscord<jmgomez> Hey guys, on windows when I specify --app:lib using clang, it generates .lib and dll files. If I not specy clang (I assume it uses the microsoft compiler) it doesnt generate the import lib file, just the dll. How can I generate the missing import lib file?
17:12:17*noeontheend joined #nim
17:16:52FromDiscord<Bloss> In reply to @QueenFuckingAdrielle "I'm considering supporting rust": nim is closer to go than rust IMO but for your use case rust is likely good
17:21:24FromDiscord<Bloss> In reply to @jmgomez "Hey guys, on windows": are you using `{.dynlib.}` pragma? I think if nothing gets dynlib exported the microsoft compiler simply does not generate a .lib file. Mingw on the other hand generates `.dll.a` files instead of .lib files
17:22:25FromDiscord<jmgomez> In reply to @blans "are you using `{.dynlib.}`": yup, Im using it
17:23:10FromDiscord<Bloss> sorry .a files are static libraries not import files
17:23:17FromDiscord<Bloss> hmm then it might be using mingw
17:24:22FromDiscord<jmgomez> can the microsoft compiler be forced?

18:53:08FromDiscord<Phil> Curiosity question, anyone here that uses other tooling than vscode + nim plugin for code?↵I find vscode + plugin to be pretty hit-or-miss on the intellisense, while it also takes randomly forever (>3seconds) sometimes to make a suggestion.

18:54:13FromDiscord<demotomohiro> I use neovim + some plugins.
18:55:17FromDiscord<Phil> As someone that never intentionally used anything other than nano for terminal command line text editors, does neovim even come with code suggestions ?
18:59:13FromDiscord<demotomohiro> I tried some Nim plugins with suggestion before but that made my neovim slow down. So I removed it. Neovim still can complement identifiers from words in opened files.
19:01:40FromDiscord<demotomohiro> If you open module.nim and write `proc fooInit` then whe you edit other file and type `foo`, neovim can suggest `fooInit`.
19:03:17FromDiscord<Phil> Hmm so essentially similar issues as vscode, suggestions work kind of, but not perfectly
19:06:03FromDiscord<demotomohiro> Im using old PC. If you have faster CPU, it might work smoothly.
19:06:59FromDiscord<Phil> I'm coding in my spare time on an 8 year old Lenovo T440, we might share similar issues 😄

19:08:32FromDiscord<Phil> I was mostly curious if there's a vastly better experience to be had in another editor with nim-intellisense

19:24:36FromDiscord<QueenFuckingAdrielle> In reply to @blans "nim is closer to": I will probably create a rust api for it. Right now the core runtime is in nim that interfaces with singularity/docker containers or processes in secondary languages or nim code. For secondary languages, python is about 50% of the way to full support. I am looking at supporting c, cpp, rust, and maybe julia in the future. I just don't know if i want to adopt rust as a 1st class languag
19:25:48FromDiscord<QueenFuckingAdrielle> this is more of strategic decision I guess. I'm not sure if I'm fully commercializing this or not, but if I do, nim is not exactly the most common skill/language among potential adopters.

19:51:39FromDiscord<jos> how do you even write a source to source compiler
19:51:53FromDiscord<jos> like do u literally just emit strings
19:52:13FromDiscord<jos> in lieu of any place u would normally emit assembly or something
19:52:57FromDiscord<jos> i tried looking at the nim compiler's source but it seems a little messy and maybe not the way u wanna do it

20:33:53FromDiscord<leorize> nim compiler is the last place you wanna look at
20:40:39FromDiscord<leorize> and yeah you kinda emit string
20:41:37FromDiscord<leorize> but the best way to do it would be to emit an IR that is close to the target language, that way you can do more transformation/optimizations if needed

21:14:03FromDiscord<ynfle> In reply to @Isofruit "Curiosity question, anyone here": vim + nimlsp
21:15:03FromDiscord<theanxietybuster> I don’t nim much right now but I’ve been coding with ED and some wrappers shoved on top :ferrisSweat:
21:15:53FromDiscord<Phil> In reply to @rakgew "<@180601887916163073>\: I use micro": Does "hints" include getting decent function suggestions, e.g. that it suggests "someproc" in an imported file for "someobj.somep" ?
21:16:01FromDiscord<theanxietybuster> But VS2019+ also now supports building with a Makefile, so it should theoretically work for nim on Windows
21:16:53FromDiscord<Phil> In reply to @ynfle "vim + nimlsp": Do suggestions for proc-autocompletion and variable names work to your satisfaction or is that also pretty slow/incomplete sometimes?
21:17:00FromDiscord<Phil> Same for you @theanxietybuster
21:18:09FromDiscord<theanxietybuster> I haven’t tried them at all. I usually use docs and wing it. If the compiler for a language throws an error, I’ve gotten decent at figuring out where the issue was and fixing it
21:18:39FromDiscord<ynfle> In reply to @Isofruit "Do suggestions for proc-autocompletion": Definitely comlete. Randomly it stops working for a day. Not the fastest but could be my configuration, but for sure faster than VSCode. A new feature is that now it displays the documentation also once the routine (proc, func, iterator, template, macro) is chosen
21:19:13FromDiscord<theanxietybuster> I kind of want to try and see how Nim support is on OniVim2 though
21:20:03FromDiscord<theanxietybuster> Think VSCode built without Electron but with a full Vim framework as the base
21:20:14FromDiscord<Phil> In reply to @ynfle "Definitely comlete. Randomly it": Hmm I'm absolutely terrible with vim given I never even spent more than 5 consecutive minutes with it, but faster and more consistent autocomplete might just be worth it
21:32:45FromDiscord<tosh [uniware]> what compiler arguments should i use to optimize my nim code 🤔

21:37:32FromDiscord<Goel> Is `writeFile(filename: string; content: openArray[byte])` more performant than `writeFile(filename, content: string)` since it doesn't need to convert all the data to string before? I mean if i have to do a lot of data writing on files and I/O, which is the more performant approach i should use?
21:39:33FromDiscord<ynfle> In reply to @Goel "Is `writeFile(filename: string; content:": You can always benchmark with `benchy` but IO Is always for complicated I think
21:41:32FromDiscord<demotomohiro> How about to read the source code of `writeFile`?
21:46:37*PMunch joined #nim
21:48:22FromDiscord<demotomohiro> It looks like `fwrite` vs `fputs`.
21:51:17FromDiscord<ynfle> In reply to @demotomohiro "It looks like `fwrite`": Which is faster?
21:55:11FromDiscord<Goel> What is `fputs`? never read about that in the IO Module
21:58:56FromDiscord<ynfle> In reply to @Goel "What is `fputs`? never": It's a C things

22:01:15FromDiscord<ynfle> In reply to @Isofruit "Hmm I'm absolutely terrible": Here's a video. You can see the error messages on the bottom. Warnings and hints don't show up 🤷‍♂️ https://media.discordapp.net/attachments/371759389889003532/945440053583306813/Screen_Recording_2022-02-21_at_11.19.15_PM.mp4
22:03:23FromDiscord<demotomohiro> I don't know which one is faster but `fwrite` writes given length while `fputs` writes untils it read `\0`. I think their performance is almost same.
22:04:14FromDiscord<Elegantbeef> I mean doing IO is slow, so it hardly matters imo
22:05:20PMunchHmm, am I missing something here? The pure pragma says that it can be applied to objects to make them not show type information. But I can't see any difference in the generated C.. https://nim-lang.org/docs/manual.html#pragmas-pure-pragma
22:05:55PMunchI found this https://forum.nim-lang.org/t/5125 and tried again with some objects inheriting and a procedure that needs type information. But still no difference
22:05:56FromDiscord<Waldecir Santos> sent a code paste, see https://play.nim-lang.org/#ix=3Qkn
22:05:57FromDiscord<Elegantbeef> Pmunch i think it's for inheritance, i could be wrong
22:06:20FromDiscord<Elegantbeef> Perhaps try in a release build if you havent
22:06:39FromDiscord<demotomohiro> If you use `writeFile` with string parameter to write random binary data can contain 0, it might not write whole data.
22:06:42FromDiscord<Elegantbeef> Debug may leave type info to give more useful debugging?
22:07:14PMunchStill no difference..
22:07:34FromDiscord<Elegantbeef> Yea the way to write safely would be `fileName.write(myData.toOpenArrayByte(0, myData.len)`
22:07:35PMunchBy the way, this is what I'm testing with: http://ix.io/3Qko
22:07:38FromDiscord<Elegantbeef> writeFile\

22:20:04PMunchPrestige, is there anything we can do to remove these messages?
22:22:22PMunchOkay, so Nim has a pragma called `{.inheritable.}` which is mentioned a couple of places in various documentation, but hasn't gotten a section of its own. The best description of what it does comes from the inheritance section in tutorial II: You can use the inheritable pragma to introduce new object roots apart from `system.RootObj`.
22:22:48nrds<Prestige99> not really, people signing up new accounts with different IPs and spamming...
22:23:20PMunchIt seems like they all use that #MFGA hashtag though, could we simply filter messages containing that out?
22:23:25nrds<Prestige99> Maybe can instantly start kicking people quoting rasengan
22:24:20PMunchYeah I mean that message is quoted verbatim, so it shouldn't be hard to just throw in a simple filter..
22:24:27PMunchAnyways, back to inheritable!
22:24:56nrds<Prestige99> Yeah
22:25:01nrds<Prestige99> asking some mods about it
22:25:37PMunchSo with an object marked as `{.inheritable.}` it ends up creating an object with a type field, this holds the specific type of the object that is currently being created.
22:29:47PMunchThis means that it can be used for normal inheritance checking stuff like you would expect with e.g. RootObj
22:30:40PMunchAttaching the `{.pure.}` pragma along with an `{.inheritable.}` pragma means that the object no longer creates this field
22:32:13PMunchThis means that if you define one object with fields `x` and `y`, both ints, and one object with `x` which is `{.pure, inheritable.}` and then inherit that from another object which adds field `y` then the first object with both fields and the new inherited object would be the same object in memory.
22:32:29FromDiscord<Elegantbeef> It should be the same with `type MyType = object of RootObj`
22:32:41FromDiscord<Elegantbeef> Though i still dont see why these types need type information
22:33:01PMunchAs far as I can tell from the few mentions it gets in the manual this is mostly used to interface with C/C++
22:33:09PMunchWhat do you mean?
22:33:43PMunchRootObj is {.inheritable.} but not {.pure.}
22:33:51PMunchSo it has a type field in it
22:33:57FromDiscord<Elegantbeef> I dont see why value types using inheritance need type information
22:34:40PMunchTo do things like `proc myProc(x: MyBaseType) = if x of MyInheritedType: echo "Hello world"`
22:34:51FromDiscord<Elegantbeef> that can be resolved statically
22:34:52PMunchIf MyBaseType is {.inheritable.} that works fine
22:35:01FromDiscord<Elegantbeef> and it'd be `when x is MyInheritedType`
22:35:29PMunchBut if it is {.pure, inheritable.} then it fails to compile with a message that you can't use `of` with pure types
22:35:43FromDiscord<Elegantbeef> Sure but you dont need `of` for value types
22:35:55FromDiscord<Elegantbeef> They can be statically dispatched
22:36:08PMunch`is` doesn't work though
22:36:17FromDiscord<Elegantbeef> It does too
22:37:05PMunchNope: syntax error at or near ""
22:37:08PMunchCrap..
22:37:11PMunchMy paste messed up
22:37:27FromDiscord<Elegantbeef> https://play.nim-lang.org/#ix=3Qky
22:37:33PMunchhttps://play.nim-lang.org/#ix=3Qkz
22:37:46FromDiscord<Elegantbeef> I dont know i guess it's useful for manual allocated collections
22:38:33PMunchAs you can see your code only outputs "Heh" once for the type where you manually cast to MyBase
22:38:53FromDiscord<Elegantbeef> No it outputs it once for the time i dont convert it
22:39:25FromDiscord<Elegantbeef> A generic constraint that is an inherited object uses a composite type class to dispatch
22:39:34FromDiscord<Elegantbeef> So you get the proper type and dont need runtime checks
22:39:51PMunchAh right
22:40:15FromDiscord<Elegantbeef> I just dont see where you can use this type information easily since they're not the same size
22:40:23PMunchBut just using it as a type doesn't?
22:40:36FromDiscord<Elegantbeef> Nope it upcasts it to that type
22:40:47FromDiscord<Elegantbeef> which makes sense for when it's a `var T`
22:41:35FromDiscord<Elegantbeef> It's just super odd that runtime type information exists for value types to me, there's just not a case i can see it being useful
22:41:47PMunchDynamic dispatch?
22:41:47FromDiscord<Elegantbeef> Maybe methods?
22:41:52PMunchI mean that's probably why it's even there
22:42:22FromDiscord<Elegantbeef> But i mean it doesnt make much sense there either since methods dont make sense given you cannot store them heterogenously
22:42:57PMunchHmm, I was able to create a method for a pure, inheritable object..
22:43:18FromDiscord<Elegantbeef> If you attempt to make a `@[Base(), Child(), Child()` you get a runtime error
22:43:29FromDiscord<Elegantbeef> Which makes sense as there is a loss of information for that conversion
22:43:35FromDiscord<Elegantbeef> It's just a big "why" to me
22:44:55PMunchHmm, this works though: https://play.nim-lang.org/#ix=3QkC
22:45:17PMunchThis as well: https://play.nim-lang.org/#ix=3QkE
22:45:43FromDiscord<Elegantbeef> Well yea cause you have no type information
22:45:50FromDiscord<Elegantbeef> remove `pure` it errors
22:46:20FromDiscord<Elegantbeef> And cause you have no type information you cannot get the types out
22:46:43FromDiscord<Elegantbeef> https://play.nim-lang.org/#ix=3QkF
22:47:10PMunchAh of course
22:47:18PMunchHmm
22:47:30FromDiscord<ynfle> @PMunch https://play.nim-lang.org/#ix=3QkG
22:47:40FromDiscord<Elegantbeef> I think the only reason it exists is for reference objects
22:47:53FromDiscord<Elegantbeef> ynfle you're slow
22:47:59FromDiscord<ynfle> In reply to @Elegantbeef "ynfle you're slow": You're fat
22:48:04FromDiscord<Elegantbeef> Nah i'm not
22:48:16FromDiscord<ynfle> That's what your mom said
22:50:15PMunch@Elegantbeef, make them ref types though and it works: https://play.nim-lang.org/#ix=3QkH
22:50:27FromDiscord<Elegantbeef> For value type inheritance i think it can be done 100% statically, just need a macro for `x.isChildOf(MyValueType)`
22:50:35FromDiscord<Elegantbeef> Of course it works
22:50:49PMunchThe little snippet in Tutorial II says this "Ref objects should be used whenever inheritance is used."
22:50:51FromDiscord<Elegantbeef> They're now homogeneous size
22:51:02PMunchYeah I know
22:51:22FromDiscord<Elegantbeef> my point was the type information is 100% for reference inheritance
22:51:37FromDiscord<Elegantbeef> If you have value inheritance you can do it all statically without it
22:52:47FromDiscord<Elegantbeef> I guess someone needs to add that `isChildOf` macro to oopsie 😛
