02:14:01FromDiscord<Elegantbeef> About reading from stdin async
02:14:18FromDiscord<Rika> Windows standard terminal IO cannot be non blocking without an extra thread simulating it
02:14:36FromDiscord<Rika> Legitimately no way, from what I recall

03:13:51FromDiscord<Elegantbeef> Oh i misread
03:13:55FromDiscord<Elegantbeef> Lol i can read
03:14:11FromDiscord<Patitotective> anyways there is `peekStr` :p
03:14:48FromDiscord<Rika> In reply to @Elegantbeef "Oh i misread": I was gonna say
03:14:50FromDiscord<Rika> Lol
03:15:24FromDiscord<Patitotective> can i peek backwards? i need to get the start and end of line by just knowing a column
03:15:42FromDiscord<Patitotective> sort of "read line from start"
03:15:43FromDiscord<Rika> No
03:15:45FromDiscord<Patitotective> (edit) "start"" => "start of the last line""
03:15:59FromDiscord<Rika> Once it’s read you have to seek to go back
03:18:56FromDiscord<Patitotective> `setPosition(getPosition() - 1)`?
03:19:29FromDiscord<Elegantbeef> Correct
03:19:54FromDiscord<Patitotective> he can read

03:20:37FromDiscord<Elegantbeef> Only on seconds that end with 4
03:20:56FromDiscord<Patitotective> In reply to @Patitotective "`setPosition(getPosition() - 1)`?": they really like verbose names `getPos`, `setPos` was enough↵properties would also be nice `pos` `pos=`
03:21:33FromDiscord<Rika> Think that’s just because it’s old
03:22:21FromDiscord<Patitotective> old people had more time to spend it writing verbose names, i get it

05:23:55FromDiscord<demotomohiro> `thing.setLen(thing.high)`
05:25:49FromDiscord<demotomohiro> Or implement `proc delete[T](x: var seq[T]; i: BackwardsIndex)`
05:39:47FromDiscord<sOkam!> Can a variable have multiple types?↵something like `var num: int | nil`
05:40:15FromDiscord<Elegantbeef> No object variants must be used
05:40:21FromDiscord<Elegantbeef> Or in your case `std/options`
05:40:37FromDiscord<sOkam!> Otherwise, how can you check that an int has not been previously set, but still be able to handle `0` as a valid index?
05:40:53FromDiscord<Elegantbeef> `std/options`
05:43:14FromDiscord<sOkam!> that sounds way too overcomplicated. Having to need a separate int type with new procedures just for checking for -not-set- sounds not enticing 😔
05:43:30FromDiscord<Elegantbeef> What?
05:43:43FromDiscord<sOkam!> type Thing = object
05:43:50FromDiscord<Elegantbeef> you can also just do `var num = -1` if you're really after it
05:44:28FromDiscord<sOkam!> hmmm true, actually forgot that these numbers are never negative. good point!

08:22:42FromDiscord<Elegantbeef> No, but also worth noting you hide an 'error'
08:23:12FromDiscord<Elegantbeef> in your second loop you silently replace a duplicated value
08:23:34FromDiscord<Elegantbeef> That might be fine in your case though i guess
08:30:03FromDiscord<sOkam!> yeah, i know. keys won't be duplicate in this file format, so its not a problm for this usecase
08:32:29FromDiscord<Elegantbeef> Why do you even have a table then?
08:32:41FromDiscord<Elegantbeef> I dont get the point if they're set values
08:32:44FromDiscord<sOkam!> because that's what i found when searching "nim dictionary"

08:50:13FromDiscord<sOkam!> Is there an existing way to iterate through all fields of a custom object type recursively?
08:50:49FromDiscord<Elegantbeef> Nope, there is `fieldPairs` but that doesnt do it recursively
08:56:11FromDiscord<Phil> That just unrolls the loop. Though sadly we don't have a macro for unrolling a loop over compile-time seq, there is now like 3 ways to do it in a SO question that I happen to know by chance!
08:56:38FromDiscord<Elegantbeef> It doesnt "just unroll"
08:57:11FromDiscord<Elegantbeef> And cmon phil i'm pretty proud of my variation
08:57:35FromDiscord<sOkam!> sent a code paste, see https://play.nim-lang.org/#ix=4dJG

08:58:01FromDiscord<Elegantbeef> https://nim-lang.org/docs/iterators.html#fieldPairs.i%2CS%2CT
08:58:10FromDiscord<Elegantbeef> Lol the docs are wrong
08:58:17FromDiscord<Phil> Also, "unrolling" is the only thing I can see documented about it
08:58:19FromDiscord<Elegantbeef> it's `for name, field in obj.fieldPairs`
08:58:21FromDiscord<Phil> So thus "just unrolls"
08:59:05FromDiscord<Elegantbeef> Actually nevermind docs arent wrong
08:59:22FromDiscord<Elegantbeef> That's an overload for yielding over two objects of the same type
08:59:33FromDiscord<Elegantbeef> Yea that's more of how it works and less it does↵(@Phil)
08:59:41FromDiscord<Elegantbeef> Static type system requires that unroll there
09:00:56FromDiscord<Phil> Unrolled for loops also have the very nice side-effect that you can use the outputs of those loops for meta-programming, unlike real loops
09:01:11FromDiscord<Elegantbeef> What?
09:01:36FromDiscord<Phil> If you do for loop over seq[static string] the iterator-variable type is not static string
09:01:59FromDiscord<Phil> Which is really effing Annoying if you want to generate dot expressions with the strings in that seq[static string]
09:02:43FromDiscord<Phil> Got to unroll that loop over the seq[static string] in order to get the variable as static string which you can then use to generate dot expressions
09:06:39FromDiscord<Elegantbeef> Or just feed the seq to the macro
09:06:53FromDiscord<Phil> Bah, that'd mean more macro code than absolutely necessary!
09:07:08FromDiscord<Elegantbeef> he says as he has a macro to unroll the loop
09:07:23FromDiscord<Phil> exactly!

11:43:58FromDiscord<auxym> floats, as a value type, aren't nullable though. `ref float` is, but then it's just a null pointer.
11:44:00FromDiscord<Generic> it's actually pretty clever design
11:44:59FromDiscord<Generic> how zero is technically a subnormal which allows the factor to become actually zero

14:06:18*qwr . o O ( floats are NaNable... )
14:10:45FromDiscord<auxym> yes, but arkanoid said "nil"
14:11:29FromDiscord<auxym> floats can be nan, but also other subnormals, inf, -inf. which aren't really nil (= null pointer).
14:12:25qwrand its that way in any language supporting IEEE 754 floating point numbers...
14:13:02FromDiscord<auxym> yes. I just have no idea what "is nil a float nan, under the hood?" is actually supposed to mean
14:13:42FromDiscord<auxym> like, "nil in general" is a null pointer, nothing to do with any kind of float...
14:13:50ehmryyou can use NaN boxing to express nil as a hack
14:14:21ehmrythere is a buttload of NaNs waiting to be abused as special errors
14:14:23FromDiscord<auxym> you can, but that's not implemented natively in nim
14:14:39FromDiscord<auxym> and not part of ieee 754
14:14:47ehmryright, because floating point isn't native in any modern languages
14:16:00ehmrythe hardware does extra exception handling and then it is always thrown away
14:16:09qwrimho it wouldn't be worth of the effort anyway, because it's pretty rare to actually need an optional float value - and in that case the programmer is free to do its own NaN hacks to optimize
14:16:38FromDiscord<auxym> I'm not sure I follow. float is indeed what I would consider a "native" type of the nim language (it's implemented in the stdlib/compiler). CPUs have FPUs to "natively" handle floats.
14:17:13ehmrybut you don't "natively" interact with the FPU the way it was intended
14:18:46ehmrywhatever, I just don't like floats

14:26:55ehmrywe also don't have float16 support but I don't know who does
14:28:13FromDiscord<Generic> cpus don't really suppord doing math with those
14:28:24FromDiscord<Generic> aarch64 has instructions to convert from and to them, but that's it
14:29:11FromDiscord<Generic> so float16 would mostly be just a hazard similar to <32 bit integer types

15:53:05FromDiscord<Phil> In reply to @Andycol "that fixed it!!! but": Because it could've been that you intentionally didn't put it in that context, maybe you wanted to render that string just with different variables and forgot to define them?↵The direct error it registers is that you're trying to put in variable X and X isn't defined, thus it throws that out as the error

18:44:51FromDiscord<Horizon [She/Her]> The lsp has always worked better for me, in my experience when using it on nim stable
18:50:38FromDiscord<Horizon [She/Her]> God i really want Nim to improve their lsp
18:50:46FromDiscord<Horizon [She/Her]> Editor support in general
18:50:50FromDiscord<Horizon [She/Her]> It's so helpful when it works
18:52:19FromDiscord<Bung> someone has done some contribution to nimsuggest recently
18:59:39FromDiscord<Horizon [She/Her]> Oh?
18:59:50FromDiscord<Horizon [She/Her]> My issue rn is nimlangserver won't even compile and I'm trying to tinker lol
18:59:57FromDiscord<Horizon [She/Her]> Is there a way to ignore gcsafe warnings?
19:04:08FromDiscord<Horizon [She/Her]> Ah, compiling with laxEffects works, I'm assuming it's because of the strictEffects option now becoming the default
19:16:11FromDiscord<hovsater> sent a code paste, see https://play.nim-lang.org/#ix=4dMq
19:21:37FromDiscord<hovsater> I've tried doing `nim c -l='-F /Library/Frameworks -framework SDL2' part1.nim` and while that makes the code compile, it still complains about not finding the dylib (`could not load: libSDL2.dylib`).
19:30:42FromDiscord<hovsater> Got it working! Compiling with `nim c --dynlibOverrideAll -l='-F /Library/Frameworks -framework SDL2 -framework SDL2_ttf' part1.nim` seem to do the trick.
19:31:26FromDiscord<hovsater> It's a shame the book doesn't help you out. Especially since you may not have been exposed to a compiler/linker if you've only done say Ruby and web development.

20:32:19FromDiscord<Mike> linux-only is fine for now. I'll figure it out on windows if I really need to
20:46:03FromDiscord<hotdog> Hey @hovsater welcome 🤗 Nim is often thought of as a “systems programming language” and has an assumption that the user is familiar with other systems languages like C. Please don’t let that put you off, it’s a great way to get into programming at a lower level than ruby

22:13:58FromDiscord<haywireSSC> Why does nim compile to c
22:14:11FromDiscord<haywireSSC> Instead of machine code directly
22:14:31arkanoidis it possible to create a stack-only table?
22:14:37FromDiscord<Elegantbeef> It gives you some wonderful capabillities
22:14:50FromDiscord<Elegantbeef> Human readable IR(yes llvm exists), the abillity to use obscure compilers for obscure hardware
22:15:18FromDiscord<Elegantbeef> Depends ark, what are the types?
22:15:34arkanoidfloat
22:15:40arkanoidfloat64 actually
22:15:54FromDiscord<Elegantbeef> The key is a float and the val is a float?
22:16:19FromDiscord<Elegantbeef> Is this for a LUT?
22:16:30arkanoidactually, my fault, the key is an int, the value is a float
22:16:37arkanoid(just found a bug in my code, lol)
22:17:22arkanoidinitTable[int, float](100) allocates on the heap, right?
22:17:24FromDiscord<Elegantbeef> Really you can only use an array then, and that's assuming you have a subset of values and dont want all integers being supported
22:17:31FromDiscord<Elegantbeef> Yes tables are heap allocated
22:17:48arkanoidso you suggest an array of (int, float) ?
22:17:59FromDiscord<Elegantbeef> Tables are dynamically allocated since they can have N number of elements and are a sparse collection
22:18:10FromDiscord<Elegantbeef> Well depends what you're doing
22:18:15FromDiscord<Elegantbeef> You havent given much to work with
22:19:26arkanoidit's ok, it's sufficient to know that tables are on heap, and that I have to roll my own solution
22:19:36arkanoidit's not rocket science :P
22:19:47FromDiscord<Elegantbeef> Well it depends on what you're doing
22:20:00FromDiscord<Elegantbeef> Like that's a very important question
22:20:54arkanoidoptimizing an algoritm for science! I'm porting a python thing to nim, I'm already having 10000x faster code than before, but not yet fast as the reference algorithm, which is in C
22:21:11arkanoidand valgrind tells me that I'm doing allocations, so I'm replacing those parts
22:21:51FromDiscord<Elegantbeef> you could always just preallocate more data for the table
22:22:13arkanoidexactly
22:22:15FromDiscord<Elegantbeef> How many entries do you have in the table anyway
22:22:27arkanoidan huge number ... 6
22:22:42FromDiscord<Elegantbeef> So then what's wrong with `array[6, float]` 😄
22:23:15arkanoidnothing wrong, but actually I need array[6, (int, float)]
22:23:33FromDiscord<Elegantbeef> Well then there you go
22:23:57FromDiscord<Elegantbeef> Likely faster than a hash table
22:24:16arkanoidsure, I came here for the table-heap thing :P I was confused by the "initTable" naming. Init usually is for stack
22:24:22arkanoidnew for heap
22:24:41FromDiscord<Elegantbeef> well the `Table` is stack allocated
22:24:41FromDiscord<Elegantbeef> But the table data is heap allocated
22:24:57FromDiscord<Elegantbeef> Hence `newTable` which the `Table` is heap allocated
22:25:17FromDiscord<Elegantbeef> It's bad naming
22:25:28FromDiscord<Elegantbeef> should be `newTable` and `newTableRef`
22:26:40arkanoidI agree that should be newTable. Probably the target is to match the "value semantics" but then you should also name initSeq, not newSeq
22:26:52*wallabra quit (Ping timeout: 252 seconds)
22:28:52FromDiscord<Elegantbeef> Yea there is some naming issues there, plus the entire `newT` is garbage
22:29:32arkanoidI'm very curious about tomorrow's videos
22:38:46*wallabra joined #nim
22:43:42FromDiscord<Patitotective> me too
23:22:02FromDiscord<Mike> I wanted to watch them live, but I just realized it will be like 2am for me \:/
23:23:49FromDiscord<Patitotective> how could i use `runeAt` with a stream? 🤔
23:27:01FromDiscord<Patitotective> i think i can `peekStr(maxRuneLen)` and then runeAt that string
23:27:18FromDiscord<Patitotective> though i dont know whats the max length for a rune
23:32:48FromDiscord<Patitotective> https://github.com/johnnovak/gridmonger/blob/9053a50e745d531e9405a64a0dbd3f6b1dbe8728/src/hocon.nim#L30 🧐
23:45:37FromDiscord<Elegantbeef> Max length of a rune is 4

23:45:57FromDiscord<Patitotective> literally just found that
23:46:00FromDiscord<Patitotective> :]
