02:26:43FromDiscord<TryAngle> hmm I ran into a "weird issue"↵my goal↵implement something that requires division of two numbers but I want it for float and ints
02:28:32FromDiscord<TryAngle> I think a quick fix is implementing a "unified" div ↵or a div for floats lol
02:29:15FromDiscord<TryAngle> is there a reason that there is no `div` for floats?
02:29:48FromDiscord<Rika> because it makes no sense?

02:33:12FromDiscord<impbox [ftsf]> because there is `/` for floats
02:33:20FromDiscord<TryAngle> In reply to @Rika "because it makes no": o_O ↵I might misunderstand the intention of div
02:33:45FromDiscord<TryAngle> In reply to @impbox "because there is `/`": yes but `/` for ints produces floats
02:33:48FromDiscord<Rika> integer division when you do not want floats
02:34:00FromDiscord<impbox [ftsf]> `div` computes integer division
02:34:10FromDiscord<impbox [ftsf]> i guess you might want integer division of floats
02:34:14FromDiscord<Rika> there are scenarios where you do not want float division
02:34:28FromDiscord<impbox [ftsf]> and float division of ints
02:34:37FromDiscord<impbox [ftsf]> but both would use internal conversions
02:35:09FromDiscord<impbox [ftsf]> but you could define them if you want them
02:35:17FromDiscord<TryAngle> In reply to @impbox "i guess you might": I want to write an algorithm that works for ints aswell as for floats that requires a division that produces the respective type
02:35:17FromDiscord<impbox [ftsf]> but their use case is pretty niche
02:35:36FromDiscord<impbox [ftsf]> @TryAngle you can use `when x is SomeFloat:`
02:35:40FromDiscord<impbox [ftsf]> to use / else div
02:35:42FromDiscord<Rika> In reply to @TryAngle "I want to write": when T is int: ...div... elif T is float: .../...
02:36:06FromDiscord<TryAngle> ah true that works 🤔
02:36:13FromDiscord<impbox [ftsf]> but you might want to use / in either case and convert to float and back for ints
02:36:18FromDiscord<impbox [ftsf]> depending on your requirements

02:41:55FromDiscord<TryAngle> ok I guess I add "div" for floats lol
02:58:34FromDiscord<Rosen> you want it to return a int or a float?
02:59:34FromDiscord<Rika> In reply to @TryAngle "I want to write": this
02:59:39FromDiscord<Rika> ints for int, floats for float
02:59:57FromDiscord<Rika> In reply to @TryAngle "ok I guess I": i would highly suggest not doing this if you are releasing this as a library
03:05:38FromDiscord<TryAngle> In reply to @Rika "i would highly suggest": hmm ok I reconsider this then, I thought div would be same type while / is a conventient way to write fractions lol
03:05:52FromDiscord<TryAngle> (edit) "div" => "`div`" | "/" => "`/`"
03:06:06FromDiscord<Rika> well it isnt
03:06:29FromDiscord<Rika> what function are you making that needs int -> int and float -> float and ALSO does division?
03:06:42FromDiscord<TryAngle> when I want to use something like fmod from c (modulo for floats)↵nim has nothing like that right?↵so the simplest thing would just use importc progma?
03:07:39FromDiscord<leorize> @TryAngle\: I suppose you're looking for this? https://nim-lang.github.io/Nim/math#floorMod%2CT%2CT
03:08:09FromDiscord<Elegantbeef> nah `math.mod` is `fmod`
03:08:26FromDiscord<Elegantbeef> Like it's `fmod` imported from C's `math.h` 😀
03:08:38FromDiscord<Rika> speaking of which it's strange that we dont have fused divmod
03:09:52FromDiscord<TryAngle> I wanted to implement gcd and lcm↵I didn't know it was in std/math already lol

09:07:45FromDiscord<KatrinaKitten> sent a code paste, see https://play.nim-lang.org/#ix=3IVu
09:08:03FromDiscord<Elegantbeef> I mean the above work fine for me, so we'll need more i guess
09:09:24FromDiscord<KatrinaKitten> Here's a playground link for the full actual file. https://play.nim-lang.org/#ix=3IVv
09:10:19FromDiscord<Elegantbeef> Oh there is a second step of indirection
09:10:35FromDiscord<KatrinaKitten> The `s` func on its own seems to work, but `|` creates a compilation error because `input` isn't declared.
09:13:54FromDiscord<Elegantbeef> Well i removed some of what made it less readable to me but seems if you pass the type as a parameter instead of use it like a generic it seems to work https://play.nim-lang.org/#ix=3IVw
09:14:13FromDiscord<Elegantbeef> I also added `{.dirty.}` which makes the template not hygenic, but for this example it seems fine
09:15:45FromDiscord<KatrinaKitten> Hmm, very odd. That error is resolved now, need to do some finegling to clean up other issues now but I should be able to work it out now I'm past that roadblock. Thanks!
09:16:01FromDiscord<Elegantbeef> No problem
09:16:59FromDiscord<Elegantbeef> I think i see why with dirty one needs to pass a typedesc as a parameter, since it's dirty the T isnt injected as a symbol i assume
09:17:31FromDiscord<Elegantbeef> Nope that's not right 😀
09:17:45FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=3IVx
09:17:56FromDiscord<KatrinaKitten> After a little playing it works just fine continuing to use `{.inject.}` instead of `{.dirty.}`, so long as it's a `typedesc` instead of a generic.
09:18:10FromDiscord<Elegantbeef> Odd
09:18:22FromDiscord<Elegantbeef> I need to find the mechanism that causes this and see how easy it is to fix

09:26:32FromDiscord<Elegantbeef> Ah i've got it!
09:27:17FromDiscord<Elegantbeef> It's actually a generic issue not a template issue
09:29:35FromDiscord<Elegantbeef> Oh methinks i see the issue, it's attempting to semantically check this call and as such `echo(input)` fails as the generic messes with the logic

09:34:31FromDiscord<Elegantbeef> Forces `input` to remain open until the instantiation of the generic
09:35:02FromDiscord<Elegantbeef> I dont think it's possible to constrain like that
09:35:41FromDiscord<Elegantbeef> It makes 100% sense now why it errors and i think it's technically "right" though i dont know
09:36:56FromDiscord<Elegantbeef> Actually i'm wrong
09:36:59FromDiscord<Elegantbeef> You can constrain them
09:37:10FromDiscord<Elegantbeef> `[X, Y; Z: X or Y`
09:37:23FromDiscord<Elegantbeef> Or `X | Y` if you're a degenerate that likes farts or some jovial insult
09:37:56FromDiscord<KatrinaKitten> Ahhh the `;`, that makes sense. `mixin` seems to have the desired effect in this case, but I'm guessing is less typesafe?
09:38:40FromDiscord<Elegantbeef> Well `mixin` will allow selecting any variables into the scope
09:38:54FromDiscord<Elegantbeef> It's not a typesafe thing as a selecting of symbols
09:39:27FromDiscord<Elegantbeef> So basically when you instantiate a generic with `mixin` in it'll be capable of selecting any in scope, but it should always pick the one in the template
09:39:42FromDiscord<KatrinaKitten> Cool!
09:40:37FromDiscord<Elegantbeef> I'm apparently wrong, it'll crash if there is another input in scope

09:45:12FromDiscord<Elegantbeef> Ah maybe instantiating types with the parameters doesnt work
09:46:30FromDiscord<Elegantbeef> Uhh you wrote a custom `as`?

09:47:17FromDiscord<KatrinaKitten> Ah, no, that was just my offhand guess. The documentation is a pain to search through.
09:47:27FromDiscord<Elegantbeef> Nah it's just `Parser[V] (t)`
09:47:37FromDiscord<Elegantbeef> Space isnt required that's me being dumb
09:47:44FromDiscord<Elegantbeef> Any form of call works for it
09:48:18FromDiscord<Elegantbeef> I have a hypothesis for the issue so give me a moment
09:49:06FromDiscord<KatrinaKitten> That gives the same error, even if I wrap it in `cast`. I'm guessing the issue is I'm trying to get it to infer the generics and it's freaking out at `V` not having an explicitly inferable definition, even though it has a constraint that should be inferable.
09:49:49FromDiscord<KatrinaKitten> I.e. I'm calling it as `doThing(<params>)` not `doThing[<types>](<params>)`.
09:50:03FromDiscord<KatrinaKitten> (edit) "`doThing[<types>](<params>)`." => "`doThing[<types>](<params>)`, in part because of operator syntax."
09:50:44FromDiscord<Elegantbeef> Hmm
09:50:52FromDiscord<Elegantbeef> Nah i dont think so
09:51:06FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=3IVI
09:51:42FromDiscord<Elegantbeef> Can you pass the full file again?
09:52:34FromDiscord<KatrinaKitten> Ah, see, I don't have any parameters that use `V` in their type. https://play.nim-lang.org/#ix=3IVJ
09:53:01FromDiscord<KatrinaKitten> It's only used in the output type and as a parameter to the `createParserTo` template, not in any of the input parameter types.
09:53:02FromDiscord<Elegantbeef> Yea that's the issue
09:53:32FromDiscord<Elegantbeef> You can just do `Parser[T or U]` i think
09:53:54FromDiscord<KatrinaKitten> That would work, but I also
09:54:19FromDiscord<KatrinaKitten> That would work, but on passing `T or U` to `createParserTo`, it complains that it's getting a type node rather than a `typedesc`.
09:54:34FromDiscord<Elegantbeef> I meant just as the return type
09:55:06FromDiscord<KatrinaKitten> sent a code paste, see https://play.nim-lang.org/#ix=3IVK
09:55:28FromDiscord<Elegantbeef> Ah yea just do `Parser` than
09:55:46FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=3IVL
09:57:11FromDiscord<KatrinaKitten> Hmm... Let me play around a little and see if I can get it to work along those lines.
09:57:12FromDiscord<Elegantbeef> You cant really constrain return types that well
09:57:21FromDiscord<KatrinaKitten> If not, `mixin` may have to do, which is fine.
09:57:49FromDiscord<Elegantbeef> And btw `cast` is a lowlevel bit for bit cast
09:57:55FromDiscord<Elegantbeef> So it's almost never what you want
09:58:48FromDiscord<Elegantbeef> !eval echo cast[float](256)
09:58:50NimBot1.264808053353591e-321
09:58:55FromDiscord<Elegantbeef> damn bridge
09:58:58FromDiscord<Elegantbeef> Wait it worked 😀
09:59:16FromDiscord<Elegantbeef> that's `echo cast[float](256)` since it got destroyed
09:59:58FromDiscord<KatrinaKitten> Yeah, it doesn't like me trying to work around it that way since I need to wrap that entire body in a template call, rather than just the result.

10:04:44FromDiscord<KatrinaKitten> (edit) "https://play.nim-lang.org/#ix=3IVN" => "https://play.nim-lang.org/#ix=3IVO"
10:06:42FromDiscord<Elegantbeef> Yea it's too late for me to think about this
10:06:55FromDiscord<KatrinaKitten> Mood. Thanks for all the help, I should probably head to bed myself.
10:07:12FromDiscord<Elegantbeef> I can only say "probably give up the idea of constraining result"
10:07:22FromDiscord<Elegantbeef> Just make it a `Parser` and call it a day there
10:07:40FromDiscord<Elegantbeef> It's a generic so it can only return 1 possible type at a time
10:08:17FromDiscord<KatrinaKitten> Yeah, I may just have to make it so combinators like `|` can't combine parsers which return differing types.
10:08:49FromDiscord<Elegantbeef> I mean if you want to combine them you'd just need to use a tagged union
10:08:53FromDiscord<Elegantbeef> Or as Nim calls them object variants

17:48:59nrds<Prestige99> var mySeq
17:49:09FromDiscord<hmmm> ye ok but why
17:49:11FromDiscord<Rosen> declare it as var seq[string] to have the mutations persist out of the scope of the function, or make a var copy if you want to only mutate it in the function
17:50:51FromDiscord<IsaacPaul> In reply to @retkid "i forget, how do": Translate the string to a byte array and write that to a file
17:51:37nrds<Prestige99> @hmmm variables are immutable by default
17:52:20FromDiscord<hmmm> yea but why, does Araq hates mutable variables or there is some important reason for it

17:54:19FromDiscord<IsaacPaul> In reply to @hmmm "yea but why, does": immutable reduces cognitive load of the developer. You know that data can't change so you don't have to worry about it.

18:07:12FromDiscord<jfmonty2> this compiles and runs just fine, in particular it is correctly choosing the type for `len` based on `Size`
18:08:03FromDiscord<jfmonty2> but as soon as I try to define a proc that takes a `FixedSeq` as a parameter, it spits out a compile error "Cannot generate code for\: Size"
18:12:36nrds<Prestige99> Don't you need to provide the generics?

18:22:03FromDiscord<Yardanico> ah i see what you mean
18:22:14FromDiscord<Yardanico> yeah it's because in this case nim thinks splitLines is an iterator or something

18:22:57FromDiscord<Abi> which should apply to `seq[string]`, I'd have thought

18:23:31FromDiscord<Yardanico> splitLines returns seq[string] _once_
18:23:45FromDiscord<Yardanico> and yeah i think it doesn't work in 2nd case because nim takes splitLines iterator overload
18:23:56FromDiscord<Yardanico> instead of the seq[string] overload
18:24:05FromDiscord<Abi> this is what I assumed, but I thought I'd check
18:24:10FromDiscord<Yardanico> just saying - if you need indexes, just use std/enumerate for iterators :)

21:52:00FromDiscord<KatrinaKitten> Fair enough, `impl` it is. Not the end of the world haha

23:08:28FromDiscord<KatrinaKitten> Is there a way to mark a `{.deprecated.}` a symbol, but only outside of the module it's defined in? For example, for something used internally which is exposed "just in case", but shouldn't be used if it can be avoided.
23:08:37FromDiscord<KatrinaKitten> (edit) "`{.deprecated.}` a symbol," => " symbol `{.deprecated.}`,"
23:10:19FromDiscord<Elegantbeef> You could make it a template that has a macro that emits a warning used from outside the module
23:11:48FromDiscord<KatrinaKitten> It's already a macro, so that's one thing down; how would I check whether it's in the same module?

23:17:24FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=3IZC
23:17:43FromDiscord<Elegantbeef> Probably want another parameter for `warningMessage`
23:18:17FromDiscord<Elegantbeef> But that's the basic idea, what `someTemplate` does is what your macro needs to emit, and since your macro is emitting the code you might even be able to get the symbol and pass that node as a parameter to `warning`
23:18:25FromDiscord<KatrinaKitten> You know what I think I might do, I may just separate it into an internal and external version, only export the latter, and put the warning in there.

23:42:22FromDiscord<Elegantbeef> Are you sure it doesnt work?
23:42:35FromDiscord<inv> In reply to @Elegantbeef "probable even, Arc/Orc will": Yep, it is clear that logic behind it is not the same, but is it ok that arc does not work on the same code like refc?
23:42:44FromDiscord<Elegantbeef> https://play.nim-lang.org/#ix=3IZL
23:42:55FromDiscord<Elegantbeef> Yes it's ok unless you rely on the GC's collection methods
23:43:04FromDiscord<Elegantbeef> Arc is deterministic so it's so much better for many things
23:45:58FromDiscord<KatrinaKitten> In reply to @Elegantbeef "Are you sure ": Yep, even in the playground example you sent it doesn't turn off the warning as expected.
23:46:32FromDiscord<KatrinaKitten> Er, nvm, that one is working I think?
23:46:38FromDiscord<inv> In reply to @Elegantbeef "Yes it's ok unless": sorry, did not get "it is ok that it does not work" or "it is ok that it works" 🙂 In my case it is simple var a = b and some code after it
23:46:44FromDiscord<inv> (edit) "In reply to @Elegantbeef "Yes it's ok unless": sorry, did not get "it is ok that it does not work" or "it is ok that it works" 🙂 In my case it is simple var a = b and some ... code" added "simple"
23:47:10FromDiscord<inv> (edit) "that" => "-" | "-it ... works"" added "should"
23:47:15FromDiscord<inv> (edit) "works"" => "work""
23:47:40FromDiscord<KatrinaKitten> Got it! I needed to put them inside the proc where I was using the macro, rather than around the entire proc. Works like a charm now.
23:48:22FromDiscord<KatrinaKitten> Thanks again for the help, beef!
23:51:47FromDiscord<inv> @ElegantBeef I will prepare minimal example later, was trying to understand is it correct behaviour or not
