08:58:18YardanicoI'm here, but it's only 12AM :P
08:59:15miranok, i'll be gentle :D
08:59:46miranvar a = {1 .. 10} # nice and easy
09:00:20miranwhat if i want just odd numbers? i cannot do: var a = {countup(1, 10, 2)}
09:01:09Yardanicocountup is an iterator
09:01:13Yardanicoyou can use toSeq from sequtils
09:01:22miransomething like `start..step..end` doesn't exist, unfortunately
09:01:22Yardanicovar a = toSeq(countup(1, 10, 2))
09:01:25Yardanicoah
09:01:49Yardanicowell countup will work with toSeq
09:02:11Yardanicoand yeah, there's no start..step..end

09:05:18miranyes, your example works, but this doesn't: var a = {toSeq(countup(1, 10, 2))}
09:05:50Yardanicoahhh, set
09:06:23miranvar a = {1}; for i in countup(1, 10, 2): a.incl(i)
09:06:49miranugly, but i can live with it if there's nothing better
09:07:34Yardanicothere's nothing better for sets AFAIK
09:08:28miranalso there are no +=, *=, etc for sets.... :(
09:09:16Yardanicomiran, did you try these? https://nim-lang.org/docs/sets.html
09:09:20FromGitter<mratsim> what would that be miran?
09:09:30FromGitter<mratsim> union, intersect?
09:09:35mirani had an idea to make a pull request but couldn't figure out even regular +, * for sets in system.nim
09:10:02miranmratsim: instead of a = a * b #intersection
09:10:12miranyou would have: a *= b
09:10:28FromGitter<mratsim> check the link by Yardanico
09:10:59miranalso don't include these (+=, *=) versions
09:12:26miranproc `+` *[T](x, y: set[T]): set[T] {.magic: "PlusSet", noSideEffect.}
09:12:51miranthis is implementation (?) of `+` in system.nim
09:12:58*yglukhov joined #nim
09:13:03mirani have no idea what .magic. is
09:13:22FromGitter<mratsim> magic are proc defined at the compiler level
09:15:19miranok, i won't touch those, and will add procs to module sets and make pull request....

09:55:53Yardanicomiran, well I don't have stable to test, but I think it is :)

10:38:20Araqmiran: I think I know the problem
10:38:46Araqready to follow some instructions?
10:40:00miranlet's try it
10:45:16Araqsystem.nim line 3421 has
10:45:17Araqproc `$`*[T, IDX](x: array[IDX, T]): string
10:45:32Araqand also array to cstring conversions have been removed
10:45:57Araqso that $myCharArrayBuffer quietly changed its meaning
10:46:22Araqremove that `$` proc from system.nim and try to compile your project
10:46:50Araqif should now produce a compiler error where you need to fix your code
10:47:10miranok, how do i compile it? (without changing/breaking existing versions from choosenim)
10:47:27Yardanicomiran, ??
10:47:31Yardanicosystem.nim is not in compiler itself
10:47:38Yardanicoit's an stdlib module just like httpclient.nim
10:47:50Yardanicobut it's implicitly imported into any nim file
10:48:08miranok, just comment out that proc and re-run my file?
10:48:12Yardanicomiran, yes
10:48:19Yardanico*re-compile and re-run
10:49:13miranYardanico: i did that, and it is still the same (cc Araq)
10:49:28Yardanicomiran, are you sure you changed system.nim?
10:49:32Yardanicodid it show in CC step?
10:49:38Yardanicolike CC stdlib_system.c
10:50:14miranah, i probably changed it in my repo instead where i should. sorry for my stupidity
10:50:14Araqthe system.nim file you edited, write doesnotCompile() in it
10:50:32Araqif it still compiles you know it uses a different system.nimm :P
10:50:58AraqYardanico: the CC step is not relevant, we are after making the Nim compiler complain
10:51:23Araqif Nim still eats your program, it's some other problem
10:51:32YardanicoAraq, well I just mean if there's no CC step it means that system.nim wasn't actually changed
10:51:51Araqhuh I wouldn't count on that
10:52:08Araqit's a generic, it might not end up in stdlib_system.c
10:52:55miranuntil i find the correct file, Yardanico have you tried this on your system? does it work as it should?
10:53:09*user0 joined #nim
10:53:24Yardanicomiran, let me try..
10:53:32YardanicoI'll try to edit system.nim too
10:55:01Yardanicohmm
10:55:11Yardanicoafter removing this proc everything is the same
10:55:47Yardanicoand I tested that I removed the correct proc - tried echo [1, 2, 3] in another file
10:56:38miranAraq: still the same
10:56:59mirani made sure i was editing the right file with doesnotCompile()
10:57:08Araqhmm
10:59:06Yardanicomaybe it's related to slices?

15:02:30FromGitter<tim-st> What would be the best way to save the object type in an array? Should I generate an enum type for every object type?
15:02:38FromGitter<tim-st> or in a seq
15:03:39FromGitter<Quelklef> what do you mean?
15:04:59FromGitter<tim-st> I mean I want to have a seq that describes which types are allowed in a relation with my type. In Python I could use supportedTypes = [ClassA, ClassB, ClassC]
15:06:51FromGitter<tim-st> basically: Does each object type internally save its type as a unique int and can I access it, or should I make a unique enum type for each object?
15:08:35*nsf quit (Quit: WeeChat 2.0.1)
15:09:52AraqI'll be super unhelpful and tell you to use a macro instead ;-)
15:10:22FromGitter<tim-st> Thanks, I will read into it. I just wasnt sure if I missed some obvious way
15:10:52Araqthe problem is that even once you have the types as a first class entity, the classes are not uniform
15:11:09Araqso you don't store a list of classes and then iterate over it.
15:11:26Araqinstead you do code generation with a macro
15:11:46FromGitter<tim-st> ok, thanks!
15:12:24Araqmacro initAll(a: vararags[typedesc]) = result = newStmtList(); for x in a: result.add newCall(bindSym"init", x)
15:12:59FromGitter<tim-st> wow, this looks hard xD
15:13:41Araqwell you need to redesign everything but usually it works out and the result is something that fits Nim and has zero overhead
15:14:18FromGitter<tim-st> ok, that sounds good

20:20:09salewskiAraq, I still wonder how expensive type query like "if t of RStarTree[M, D, RT, LT]:" is?
20:20:48Araqthe generic is instantiated so this is the same as 't of Subclass'
20:22:36salewskiI guessed that, but have no idea how expensive 't of Subclass' is. Does it depend of number of subclasses?
20:23:15Araqit is a trivial while x != subclass: x = x.up loop
20:23:32Araqso the complexity is O(inheritance depth)
20:23:50salewskiInteresting, thanks!
20:23:58Araqthere is also some caching involved iirc
20:24:39Araqit stores successful and not successful matches to speed up things further. it's not optimal, but it also never shows up in profiles
