00:00:06FromDiscord<QuiteQuietQ> ok, I thought there is something similar to `setTimeout` :D... and I read the code on geeksforgeeks wrong, it is not using set timeout, nvm
00:05:01FromDiscord<Gumbercules> Oh for the JS backend yeah
00:05:15FromDiscord<Gumbercules> I figured you were referring to the C backend, apologies
00:07:59FromDiscord<BobBBob> it seems like most nim code has any custom types in one big block at the top of the code, but whats the "standard" way to organize procs after that? because usually in other languages you have method functions for a type and they all get bunched together but nim doesnt really have those so you could put them wherever
00:15:48*fallback quit (Quit: IRCNow and Forever!)
00:16:21FromDiscord<Elegantbeef> Indeed you can put them anywhere
00:16:31FromDiscord<Elegantbeef> Generally you write the code in such away that you build upon previous things
00:17:36FromDiscord<PunchCake> Sooo guys
00:17:59FromDiscord<PunchCake> I need an easy to use mobile framework for nim
00:18:11FromDiscord<Elegantbeef> Unlike other languages aside from hooks there are no concepts of type bound operations really(araq wants to change this) so there is no real enforced design requirement
00:18:12FromDiscord<PunchCake> It doesnt matter if its native or not
00:18:23FromDiscord<Elegantbeef> Your options are very limited
00:18:31FromDiscord<PunchCake> What are my options
00:18:39FromDiscord<PunchCake> I heard about wiish for nim
00:18:46FromDiscord<PunchCake> Aka why is it so hard
00:18:53FromDiscord<PunchCake> To make a cross platform app
00:18:56FromDiscord<Elegantbeef> Partly due to how mobile works, partly due to the small dev pool
00:18:57FromDiscord<Elegantbeef> nimx and fidget work iirc
00:19:41FromDiscord<PunchCake> Nimx looks very ugly
00:19:52FromDiscord<Elegantbeef> Nice
00:19:58FromDiscord<PunchCake> To the point where if I'd ship my app I'd get bitch slapped to oblivion
00:20:12FromDiscord<Elegantbeef> Cool, perhaps Nim isnt for this project
00:20:15FromDiscord<Elegantbeef> Atleast for the frontend
00:20:41FromDiscord<Elegantbeef> You could use kotlin or java for the front end and call into native Nim code
00:20:54FromDiscord<PunchCake> I dont know why is it this hard
00:21:16FromDiscord<PunchCake> Opengl can run on nearly every major os
00:21:21FromDiscord<PunchCake> Including mobile
00:21:26FromDiscord<Elegantbeef> Cause mobile devices are designed in such a way to encourage the use of specific languages
00:21:51FromDiscord<PunchCake> Welp react native is used a lot in production
00:22:00FromDiscord<PunchCake> And look at it its doing very well
00:22:07FromDiscord<Elegantbeef> You can technically use any language but you're encouraged to use JVM and Swift
00:22:31FromDiscord<Elegantbeef> It's not an easy task to replicate react unpaid
00:22:42FromDiscord<Andreas> In reply to @Elegantbeef "Cause mobile devices are": yes, IOS lingua-franca = Swift | Android= Java
00:22:45FromDiscord<PunchCake> The thing is kotlin itself is simple but the amount og complexity of the apis is insane
00:23:16FromDiscord<PunchCake> (edit) "og" => "of"
00:23:42FromDiscord<Elegantbeef> 2400 contributors and funded/developed by facebook
00:24:02FromDiscord<PunchCake> Hm yeah
00:24:15FromDiscord<PunchCake> I dont really understand why we are forced to use java for android
00:24:41FromDiscord<Elegantbeef> Ok so then time for you to make a Nim cross platform GUI for Desktop and Mobile
00:24:54FromDiscord<Elegantbeef> Cause that's the language all of their OS interaction is written in
00:25:09FromDiscord<PunchCake> I thought about it
00:25:09FromDiscord<Elegantbeef> To use other languages you have to bind to that code somehow
00:25:29FromDiscord<BobBBob> isnt there qt bindings for nim now
00:25:36FromDiscord<PunchCake> There is
00:25:39FromDiscord<Elegantbeef> Sure but QT doesnt support mobile
00:25:47FromDiscord<PunchCake> It does bro
00:25:49FromDiscord<PunchCake> Qt5
00:26:17FromDiscord<Elegantbeef> Guess i was thinking gtk
00:26:48FromDiscord<BobBBob> good luck getting it to work well on mobile though haha
00:26:52FromDiscord<Elegantbeef> If you really wanted to you could use the JNI to wrap the relevant java class you wanted
00:27:09FromDiscord<Elegantbeef> But anything is going to be much more work than just using a JVM language
00:27:26FromDiscord<PunchCake> Agreed
00:27:41FromDiscord<PunchCake> Maybe i could put in the work so other devs dont have to go through this bullshit
00:27:48FromDiscord<PunchCake> Aka take one for the team
00:28:32FromDiscord<PunchCake> Or i could just use react native its plenty fast and easy to use
00:28:54FromDiscord<BobBBob> if I remember the reason android is based around java is because back when it started it was to ensure cross platform compatibility and now theyve already got everything in java so they just have to go with it, as for apple it's just standard apple vendor lock in
00:29:13FromDiscord<Elegantbeef> It's not even really vendor lock in anymore in apple's case
00:29:27FromDiscord<Elegantbeef> Just a bit of NIH mixed with fancy ideas
00:29:39FromDiscord<PunchCake> In reply to @BobBBob "if I remember the": Idk why they didn't make their own language tailored for android
00:29:45FromDiscord<BobBBob> In reply to @Elegantbeef "Just a bit of": pssh that's what they tell you
00:30:05FromDiscord<Elegantbeef> Swift is now a cross platform language
00:30:09FromDiscord<BobBBob> In reply to @PunchCake "Idk why they didn't": i think it was originally a small independent project before getting bought (?) by google
00:30:09FromDiscord<Elegantbeef> Not that any one uses it as one
00:30:11FromDiscord<PunchCake> Nice joke
00:30:15FromDiscord<Elegantbeef> But it's totally allowed now
00:30:36FromDiscord<PunchCake> Bro fr?
00:30:47FromDiscord<PunchCake> I can use swift for cross plat dev now
00:30:57FromDiscord<Elegantbeef> Yes
00:31:08FromDiscord<PunchCake> The thing is i dont wanna support this walled garden bollocks so i dislike swift
00:31:53FromDiscord<PunchCake> And i think nimqt is the most reliable and stable bindings avaliable for qt right
00:32:42FromDiscord<Elegantbeef> If I really wanted to use Nim I'd just use either react native or a JVMlanguage / swift and call into a Nim dynamic library
00:32:56FromDiscord<Elegantbeef> Anything else is just an exuberant amount of time
00:33:16FromDiscord<PunchCake> So basically write all the logic in nim and write all the ui in js with the button callbacks
00:33:21FromDiscord<PunchCake> Sounds like a good idea

01:05:24FromDiscord<Nilts> Could be on a completely different line. Nim's bug reporting has done that too me.
01:05:32FromDiscord<spoon> how are you compiling it?
01:05:44FromDiscord<spoon> are you running `nim js filename.nim`?
01:06:56FromDiscord<Nilts> In reply to @spoon "are you running `nim": no other flags
01:08:03FromDiscord<spoon> hmm, are you using the function from jscore for compatibility reasons or something?
01:08:55FromDiscord<Nilts> In reply to @spoon "hmm, are you using": I am pretty sure it is the only one. And it is native, so faster ig
01:09:20FromDiscord<spoon> the one from times does work, i tested with the js backend to make sure
01:09:45FromDiscord<Nilts> In reply to @spoon "the one from times": also, I want an int, not a datetime
01:11:03FromDiscord<spoon> if you know what unit it uses there are functions to convert it into s, ms, unix time, etc
01:11:30FromDiscord<spoon> but since mine compiles i imagine the problem might be on another line
01:11:53FromDiscord<Nilts> In reply to @spoon "but since mine compiles": arg, nim's buggy error reporting
01:12:21FromDiscord<spoon> sent a code paste, see https://play.nim-lang.org/#ix=4rEr
01:12:23FromDiscord<Nilts> I just realized. It only tracks like every 5 lines for the js backend

06:05:04FromDiscord<kubo39> what is over- or underflow errors? they seems totally different..
06:09:40FromDiscord<Elegantbeef> They're idientical some operation would have caused an integer to either go under `int.low` or above `int.high`
06:09:52FromDiscord<Elegantbeef> identical even
06:11:18FromDiscord<kubo39> i know it is overflow.
06:11:38FromDiscord<Elegantbeef> What?
06:11:57FromDiscord<Elegantbeef> Overflow is going over int.high, underflow is going under int.low
06:12:36FromDiscord<kubo39> typically underflow means floating point underflow AFAIK.
06:12:44FromDiscord<kubo39> https://en.wikipedia.org/wiki/Arithmetic_underflow
06:13:42FromDiscord<Elegantbeef> > When the term integer underflow is used, the definition of overflow may include all types of overflows, or it may only include cases where the ideal result was closer to positive infinity than the output type's representable value closest to positive infinity.
06:13:43FromDiscord<kubo39> going under int.low is also overflow
06:14:04FromDiscord<Elegantbeef> integer underflow is also an acceptable term for going below int.low
06:14:44FromDiscord<Elegantbeef> There is a whole entry about the definition and it's ambiguity
06:16:27FromDiscord<Elegantbeef> So i'd say that given colloquialisms it's fine to call below low is underflow
06:18:36FromDiscord<kubo39> oh, I've found these sentence in integer overflow page.
06:20:35FromDiscord<Elegantbeef> One of those cases when the term makes sense in the context sorta, so it's adopted as an acceptable term

11:34:54FromDiscord<Yardanico> `proc contains[T](a: typedesc[range], b: T): bool = b in a.low..a.high` courtesy of beef
11:35:33FromDiscord<Yardanico> then you can just do `echo 1 in Natural` because in Nim `in` operator calls `contains` overloaded for the types you're checking
11:36:32FromDiscord<Yardanico> In reply to @choltreppe "hey all, I want": You can actually do a similar thing but do it with `compiles` so that the code is checked to be side-effect free at compile-time, and then you error if it's not
11:36:45FromDiscord<Yardanico> https://forum.nim-lang.org/t/2923 for example

11:45:02FromDiscord<ieltan> Oh, what about `Positive` ?
11:45:24FromDiscord<Yardanico> what about it?
11:45:25FromDiscord<ieltan> its a range too oosp
11:45:51FromDiscord<Yardanico> In reply to @ieltan "its a range too": if you just want to check for numbers being in some range, you can just write procs that check it
11:45:59FromDiscord<Yardanico> ranges are just a short-hand for checking if a number is in the range manually
11:46:20FromDiscord<Yardanico> and for documenting needed arguments better
11:46:33FromDiscord<choltreppe> my original problem was that I wanted to assert specific variables dont get modified. so I noticed noSideeffect would be too harsh. and since I know wich vars are of interrest I can just do the good old `let x = x` showdowing inside a block trick.
11:47:54FromDiscord<ieltan> In reply to @Yardanico "if you just want": I already did that and I just want to avoid floats and negative numbers, but x.Natural takes cares of not having floats
11:48:00FromDiscord<ieltan> negatives are still a problem
11:48:19FromDiscord<Yardanico> not sure what you mean, use positive?
11:49:12FromDiscord<ieltan> Yeah i got it, thanks !
11:49:32FromDiscord<Yardanico> In reply to @ieltan "Yeah i got it,": also btw, ranges aren't some special magic, you can just define them in your own code too

13:11:00FromDiscord<spoon> i'd have to run benchmarks but on old memory management models i never had a problem with allocating external c anything
13:24:03FromDiscord<Gumbercules> In reply to @konradmb "Wait, what? So gc": No it won't. Use c_free.
13:24:48FromDiscord<Gumbercules> The memory wasn't allocated using Nims allocator - it doesn't have anything to do with GC.
