02:08:10FromDiscord<Elegant Beef> I could be wrong but i think the template generates an identfier with gensym which causes an issue with the macro invoke
02:13:13FromDiscord<UNIcodeX> it doesn't like `fmt`. If I use `"$1 : $2".format(cpuTime()-tStart, label)` it works....
02:13:19FromDiscord<Elegant Beef> Well yea
02:13:24FromDiscord<UNIcodeX> but.... I lose formatting.
02:13:24FromDiscord<Elegant Beef> https://play.nim-lang.org/#ix=2ySz this works aswell
02:13:57FromDiscord<Elegant Beef> I dont know the properway to use the template identifier for the macro, but what i just did is a dumb method of doing it
02:14:26FromDiscord<UNIcodeX> I didn't know about inject pragman
02:14:27FromDiscord<UNIcodeX> (edit) 'pragman' => 'pragma'
02:14:44FromDiscord<Elegant Beef> Well it's akin to properly declaring a variable so it's not proper to use here i imagine
02:14:57FromDiscord<Elegant Beef> Since if you dont block it, it defines tElapsed into scope
02:15:30FromDiscord<Elegant Beef> So it works but until someone smarter than me says if it's a hack or a proper fix i still fill iffy about using it 😄
02:15:37FromDiscord<Elegant Beef> feel*
02:20:44FromDiscord<UNIcodeX> > Well it's akin to properly declaring a variable so it's not proper to use here i imagine↵@Elegant Beef interesting, but I'm getting this `Error: undeclared identifier: 'label'`
02:20:51FromDiscord<UNIcodeX> straight copy and paste

02:21:13FromDiscord<Elegant Beef> I mean works on nim playground
02:21:59FromDiscord<Elegant Beef> oh
02:22:05FromDiscord<Elegant Beef> forgot that you pass a string to the template
02:27:46FromDiscord<Elegant Beef> I say just clap your hands until someone that knows templates shows up 😄
02:33:37disruptekyou can use .inject in the params, too, but i can't even tell what you're trying to accomplish.
02:34:11FromDiscord<UNIcodeX> I'm just trying to find out how long certain parts of a procedure take.
02:35:36disrupteki usually try: body finally: evho
02:37:18disruptekyou can var foo {.inject.}: string and then set it inside the body; just insert your declaration in front of the body. the body can access it because it's in scope.
02:38:10disruptekif you want to access something local but not necessarily in the caller, you use bindsym.
02:41:14FromDiscord<flywind> May be better not to use `fmt` in templates.
02:41:58FromDiscord<flywind> I have ever written similar program without `fmt` https://github.com/xflywind/timeit/blob/ba4e90546af33632aea06208bc0f2d33418d2558/src/timeitpkg/main.nim#L146

04:51:17FromDiscord<iWonderAboutTuatara> Hey everyone
04:51:23FromDiscord<iWonderAboutTuatara> ah dammit beef is offline
04:51:41FromDiscord<iWonderAboutTuatara> trying to implement a `->` instead of a `:` for proc return types to learn more about macros
04:52:05FromDiscord<iWonderAboutTuatara> and I'm getting really stuck on how to loop through something here
04:52:25FromDiscord<iWonderAboutTuatara> when i take `->` as the macro I don't get a NN with the full proc decl
04:52:29FromDiscord<iWonderAboutTuatara> so It's hard to work with
04:59:12FromDiscord<Elegant Beef> Dammit sucks he's offline
05:00:54FromDiscord<iWonderAboutTuatara> lmaoo
05:01:05FromDiscord<iWonderAboutTuatara> glad you're here, you're the expert on this kind of thing
05:01:10FromDiscord<iWonderAboutTuatara> any way to test this kind of thing?
05:01:17FromDiscord<iWonderAboutTuatara> sent a code paste, see https://play.nim-lang.org/#ix=2ySY
05:01:23FromDiscord<iWonderAboutTuatara> this is an AST from this statmenet
05:01:26FromDiscord<Elegant Beef> I'm not an expert
05:01:28FromDiscord<iWonderAboutTuatara> `f(s : int) -> int : return 1`
05:01:31FromDiscord<iWonderAboutTuatara> close enough
05:01:49FromDiscord<iWonderAboutTuatara> (edit) '`f(s' => '```nim↵f(s' | '1`' => '1```'
05:02:02FromDiscord<Elegant Beef> You're attempting to replicate swift return types?
05:02:27FromDiscord<iWonderAboutTuatara> idk if its in swift
05:02:33FromDiscord<iWonderAboutTuatara> attempting to replicate -> return types
05:02:37FromDiscord<iWonderAboutTuatara> but, only for pure funcs
05:02:50FromDiscord<iWonderAboutTuatara> ie using `->` indicates a func and `:` indicates a pro
05:02:53FromDiscord<iWonderAboutTuatara> (edit) 'pro' => 'proc'
05:03:15FromDiscord<Elegant Beef> Ok so what
05:03:17FromDiscord<Elegant Beef> (edit) 'what' => 'what's the issue'
05:03:31FromDiscord<iWonderAboutTuatara> When I pass this to the proc
05:03:59FromDiscord<iWonderAboutTuatara> Is it just passing the `Ident ->` or the entire Stmtlist or the infix?
05:04:28FromDiscord<iWonderAboutTuatara> How do I check what's being passed also, when writing this outside of a dumptree throws error
05:04:41FromDiscord<Elegant Beef> Well without the macro made of course it'd error
05:09:44FromDiscord<Elegant Beef> @iWonderAboutTuatara seems like you're trying to change nim's syntax which isnt allowed
05:10:47FromDiscord<iWonderAboutTuatara> not allowed?
05:10:49FromDiscord<iWonderAboutTuatara> That's sad
05:14:00FromDiscord<Elegant Beef> Actually im uncertain why it was being a pain
05:14:16FromDiscord<iWonderAboutTuatara> wdym macro mode?
05:14:20FromDiscord<iWonderAboutTuatara> bit confused
05:14:27FromDiscord<Elegant Beef> made
05:14:37FromDiscord<iWonderAboutTuatara> no doubt
05:14:50FromDiscord<iWonderAboutTuatara> but I want to know what exactly is being passed, infix or ident
05:14:59FromDiscord<Elegant Beef> Well i mean this works https://play.nim-lang.org/#ix=2yT1
05:16:27*solitudesf joined #nim
05:17:04FromDiscord<iWonderAboutTuatara> wait how is it only passing things on the left?
05:17:48FromDiscord<iWonderAboutTuatara> wait yeah how did you seperate them?
05:18:05FromDiscord<Elegant Beef> I have limited knowledge on how the parser works 😄
05:18:49FromDiscord<Elegant Beef> `->` is an operator which means it requires a macro which takes a left and right, then you know you want a body which requires an `:` or possibly `=` although im uncertain of the latter
05:19:25FromDiscord<iWonderAboutTuatara> I see
05:19:33FromDiscord<iWonderAboutTuatara> so left and right in the macro params are keywords?
05:19:40FromDiscord<Elegant Beef> Nope
05:19:57FromDiscord<iWonderAboutTuatara> parser assumes first param is left and next is right?
05:20:00FromDiscord<Elegant Beef> It's an operator so it takes a left side and a right side
05:20:05FromDiscord<Elegant Beef> Yea i think so 😄
05:20:09FromDiscord<iWonderAboutTuatara> oh interesting
05:20:21FromDiscord<iWonderAboutTuatara> this seems super complex
05:20:29FromDiscord<iWonderAboutTuatara> /confusing
05:21:24FromDiscord<Elegant Beef> Lol you can do it, it's not too bad, all you have to do is generate the identdefs for a func definition and then set it's body to what you get from the user
05:21:46FromDiscord<Elegant Beef> I believe in you!
05:22:03FromDiscord<iWonderAboutTuatara> thanks!
05:22:30FromDiscord<iWonderAboutTuatara> so because `->` is interpreted as an operation
05:22:35FromDiscord<iWonderAboutTuatara> because its an operator/symbol
05:23:13FromDiscord<Elegant Beef> Yep
05:23:17FromDiscord<iWonderAboutTuatara> it takes an operand (left side, first param) and another operand (right side, second param)
05:23:31FromDiscord<Elegant Beef> That's my take on it
05:23:34FromDiscord<Elegant Beef> I could be wrong 😛
05:23:38FromDiscord<iWonderAboutTuatara> then because of the `:` that's a third nodeset/thing so I need a third param?
05:23:50*thomasross quit (Ping timeout: 272 seconds)
05:25:13FromDiscord<Elegant Beef> Yea i think so 😄
05:25:17FromDiscord<iWonderAboutTuatara> so I think it's dependant on the number of same level nodes you need
05:25:24FromDiscord<iWonderAboutTuatara> if you take anything less then 3 here than it throws an error

05:26:02FromDiscord<iWonderAboutTuatara> sent a code paste, see https://play.nim-lang.org/#ix=2yT8
05:26:12FromDiscord<iWonderAboutTuatara> the macro itself is `Ident "->"`
05:26:28FromDiscord<iWonderAboutTuatara> We need Call block, Ident Int, and StmtList
05:26:41*apahl joined #nim
05:27:00FromDiscord<iWonderAboutTuatara> if we take any less than that in the macro, we just have either `int` or `: discard` hanging out which throws an error
05:27:05FromDiscord<iWonderAboutTuatara> specifically an indent compiler error
05:27:22FromDiscord<iWonderAboutTuatara> the first macro param takes the first same level node, ie the call
05:27:36FromDiscord<iWonderAboutTuatara> second macro param takes the 2nd same level node, ie the `Ident "int"`
05:27:50FromDiscord<iWonderAboutTuatara> third marco param takes the 3rd same level node, ie the `StmtList`
05:28:00FromDiscord<iWonderAboutTuatara> Could be completely wrong on this, but this is what I got from like 2 seconds

11:13:48FromDiscord<Rika> colons after a function call pass the statements after the colon as the last parameter of the function
11:13:52FromDiscord<lqdev> that's because you're passing a code block as the last param

11:36:31newUserhi, I have for example a #define D2PI (6.283185307179586476925287) in a C header file and want to import it into a nim file, how can I do this?
11:38:27FromDiscord<haxscramper> No, you can't directly import C defines. The Closest nim alternative would be `const D2PI = 6.283185307179586476925287`
11:40:00orazovae[m]how do I sort a sequence?
11:41:18newUserthx
11:41:19*Trustable joined #nim
11:48:23sealmovenewUser: there is a program called c2nim which does the bulk of the work, but usually you still need to tweak the result.
11:48:43newUserk
11:49:31sealmovecheck it out with `nimble install c2nim`, and then the syntax is `c2nim <c header file>` in the command-line.
11:50:28sealmovehonestly this is the only feature I am jealous of Zig...
11:51:24FromDiscord<Rika> orazovae: import algorithm and use the sort proc there
11:51:43newUseryup, works
11:51:47newUserthx
11:52:16newUserconst D2PI* = (6.283185307179586)
11:52:43newUsernice is the struct conversion....
11:52:48sealmoveand some other preprocessor stuff turn into templates
11:53:50sealmovepersonally I still find it tedious to make C bindings...
11:54:03sealmovebut maybe that's as good as it can get
11:54:11newUserI'm only playing around with it...
11:56:49FromDiscord<krisppurg> How would you do this in Nim? In python:↵`struct.pack_into(">I", header, 8, 60028)`↵I'm kind of struggling and confused with byte stuff in Nim.
11:57:17sealmovekrisppurg we don't have standard lib procs for that
11:58:12sealmovemaybe try this? https://github.com/OpenSystemsLab/struct.nim
12:00:13newUsersealmove: I have converted some procs too with c2nim, but there is missing {.importc, header:... after every proc, is it possible with one declaration to import all functions from header file
12:00:16newUser?
12:01:29sealmoveI think it's not :|
12:01:39newUserso copy and paste...
12:01:48sealmoveyou can use a seperate file and run c2nim on the header
12:02:22sealmovethen import the resulting file of c2nim
12:02:59newUseryes, but I get proc1, proc 2 etc but without proc1 {.importc, header:, proc 2 {.importc, header: ... etc
12:03:52FromDiscord<Rika> you can use a separate pragma-making pragma to at least reduce the repetition of the pragma
12:04:04sealmoveI see, maybe take a look at c2nim's options
12:04:30sealmoveif it's not possible then it's a good potential feature request for c2nim
12:04:48newUser<Rika> how this?
12:05:27newUserthe best is to have one {.importc, header: on top of the file...
12:06:01*supakeen quit (Quit: WeeChat 2.9)

12:28:54FromDiscord<shashlick> @newUser there is a header option for c2nim
12:29:04FromDiscord<shashlick> What are your wrapping though
12:29:31newUser?
12:30:46FromDiscord<Rika> there seems to be some weird issues regards varargs and async?
12:30:48newUserI have converted a header file from c to nim and have now many procs but without {.importc, header: " ... etc
12:31:19newUserto use the static lib
12:31:53newUserI have picked 2 functions and it works
12:32:27newUserbut I don't want to copy and paste 200 times and more the same importc
12:33:07FromDiscord<Rika> you can probably use the push and pop pragma
12:33:13newUserwith {.pragma: name, importc, header: ....} works but the same, copy and paste
12:33:15FromDiscord<Rika> {.push: importc....}
12:33:23FromDiscord<Rika> this will apply to all under the pragma
12:33:24newUseron top
12:33:31FromDiscord<Rika> then just {.pop.} to end it
12:33:43newUserwill try it
12:33:56FromDiscord<Rika> put it on an empty line
12:34:38bungRika I didn't know that, I remeber I can use @
12:35:31FromDiscord<Rika> well i cant access the param at all no matter what i do
12:35:37FromDiscord<Rika> so its not @ but the varargs type
12:35:41FromDiscord<Rika> thats the issue
12:35:44FromDiscord<Rika> i believe
12:38:35newUser<Rika> biggggg smilleeee, thx
12:38:44newUserit works
12:38:55newUserbut after push no :
12:39:00FromDiscord<Rika> yes
12:39:02FromDiscord<Rika> its not a block
12:39:05FromDiscord<Rika> its just a pragma
12:39:09FromDiscord<Rika> its kinda weird but eh
12:39:57newUserhurray.... thx a lot, have a nice sunday, bye

14:26:36sealmove@Rika just to clarify: after this `push` pragma you still have to declare all procs in nim right?
14:27:26sealmoveI wonder if nim could somehow implement seemless interop with C, since it compiles to C...
14:27:36FromDiscord<Rika> yes
14:28:19sealmovefor example Zig has this feature, but Zig is a C compiler, it doesn't compile to C, so I don't know...
14:29:33FromDiscord<Rika> nim is not a c compiler
14:30:53sealmoveI guess Nim compiler would have to generate and inject the Nim declaration itself. Theoretically it's possible right?
14:31:27FromDiscord<Rika> is there a reason you arent using nimterop
14:32:46*bosyf joined #nim
14:33:55bosyfhas anyone noticed there is no slice assignment for seqs? you cant do s[1..3] = @[1, 2, 3] for example but you can for arrays
14:34:18sealmoveDoesn't nimterop depend on c2nim? meaning it has the same limitations. I guess it's not a matter of integrating it into the Nim compiler but rather improving c2nim.
14:34:30FromDiscord<Rika> look into it
14:35:03bosyflike you can set slices of arrays to either seqs or arrays, but you cant set slices of seqs to anything
14:35:23FromDiscord<Rika> probably just an oversight bosyf
14:37:16bosyfoh, my bad, i was assigning a seq of ints to a seq of bytes

16:53:21FromDiscord<haxscramper> Using the same syntax as in`case`

17:17:41ZevvCan't you save it in the closure?
17:18:09FromDiscord<Recruit_main707> i dont think so

17:59:26AdeonI know there is {.gensym.} like "var something {.gensym.} =" but I wonder how the function itself would be used
17:59:55FromDiscord<haxscramper> You should use it in macros like `let variable = genSym(nskLet, "varname")`
18:00:19Adeonah right yes
18:00:22FromDiscord<haxscramper> Templates are hygienic by default and there is no need to create unique identifiers explicitly
18:01:41Adeonthanks
18:01:48FromDiscord<haxscramper> Why `echo typeof((@[1,2,3][0..2]))` is `int` but the same expression evaluated - `echo (@[1,2,3][0..2])` clearly gives `seq[int]`

18:08:35FromDiscord<iWonderAboutTuatara> was just a debugging thing

18:13:51FromDiscord<iWonderAboutTuatara> for `f(a, b, c, int) -> int: return 1`
18:14:13FromDiscord<iWonderAboutTuatara> the issue is that the third thing I add to idefs (int) is set as the value of C
18:14:15FromDiscord<iWonderAboutTuatara> instead of the type
18:14:45FromDiscord<iWonderAboutTuatara> I know nim static type uses a default value
18:14:51FromDiscord<iWonderAboutTuatara> (I think anyway)
18:17:07FromDiscord<iWonderAboutTuatara> but is there a less painful way to make this work than a lot of if/switch statements?
18:19:41FromDiscord<haxscramper> Sorry I don't really follow what are you trying to do here, especially that part with "third thing I add to idefs (int) is set as the value of C".
18:20:14FromDiscord<lqdev> btw @iWonderAboutTuatara `left[1..^1] == left[1..left.len - 1]`
18:20:24FromDiscord<haxscramper> You need to pass /value/ instead nim node for `c`?
18:27:41FromDiscord<iWonderAboutTuatara> oh you can ^1, forot about that
18:27:59FromDiscord<iWonderAboutTuatara> I want to declare those params to not have inital values

19:10:28FromDiscord<iWonderAboutTuatara> I was told this is the correct way to assign a type and not a value
19:10:54FromDiscord<iWonderAboutTuatara> earlier, the identdefs were saying that `c = int` instead of `c : int`
19:10:56FromDiscord<Yardanico> but we're doing proc definitions there
19:11:39FromDiscord<iWonderAboutTuatara> what should I be doing instead?
19:11:54FromDiscord<iWonderAboutTuatara> I removed the varsec line, somehow works properly
19:12:13FromDiscord<iWonderAboutTuatara> the error is still there, but it says `a, b, c : int` now
19:12:32FromDiscord<iWonderAboutTuatara> (edit) '`a,' => '`var int, a,' | 'c :' => 'c:'
19:12:46FromDiscord<iWonderAboutTuatara> which is confusing, where is the var coming from?
19:13:03FromDiscord<iWonderAboutTuatara> nevermind, fixed that
19:13:37FromDiscord<iWonderAboutTuatara> this stuff is confusing, now I'm getting `illformed AST: a`

19:16:04FromDiscord<iWonderAboutTuatara> huh weird
19:16:13FromDiscord<iWonderAboutTuatara> I don't see anything you're doing too differently
19:16:42FromDiscord<iWonderAboutTuatara> like obviously your code is just way cleaner and better overall, but interms of what it's doing I don't see the difference
19:16:44FromDiscord<iWonderAboutTuatara> odd
19:17:21FromDiscord<iWonderAboutTuatara> oh I see, you explicitly made idefs an @[]
19:17:26FromDiscord<iWonderAboutTuatara> thanks!
19:29:08*giannicozy joined #nim
19:29:28giannicozyHello, I am just wondering, will version 1.3 be released any time soon?
19:31:26FromDiscord<Recruit_main707> the way nim versions work is:↵odd versions are stable releases↵and even versions are nightlies, which are essentially released every day or two and are the latest ones (when they are released that is)
19:31:27FromDiscord<Rika> the next version will be 1.4
19:31:48FromDiscord<Rika> even versions are not nightlies?
19:31:58FromDiscord<Rika> thats backwards
19:32:32FromDiscord<mratsim> Anyway to have non-inlined const, I get my huge big int arrays duplicated in every file that uses them, meaning everywhere.
19:32:50FromDiscord<Recruit_main707> the translator switched the orders smh
19:33:06giannicozyWell, I found a lot of bugfixes for my code in the github, but I don't really want to use a development version yet. I just want to know if I should endure the bugs a little longer or if the stable version is close to ready.
19:33:38FromDiscord<Recruit_main707> whats wrong with nightlies?
19:34:18FromDiscord<Recruit_main707> you dont need to clone the code and build it, they are the same as the normal installation
19:35:42*Trustable quit (Remote host closed the connection)
19:35:49FromDiscord<iWonderAboutTuatara> wait @Yardanico I'm still super confused
19:36:12FromDiscord<iWonderAboutTuatara> how are what you did and what I did different?
19:36:17FromDiscord<iWonderAboutTuatara> https://play.nim-lang.org/#ix=2yXt
19:36:19giannicozyOh, well, that's good to know, but I guess I feel a little unsafe using them. I would really like to install the version once and not have to care for a while. But I guess if I want that then I'm not exactly looking for the cutting edge stuff.
19:36:22FromDiscord<Yardanico> you used toSeq incorrectly
19:36:32FromDiscord<iWonderAboutTuatara> wdym?
19:36:39FromDiscord<iWonderAboutTuatara> the reprs of both are the same
19:36:49FromDiscord<Rika> are the treereprs the same though
19:37:06FromDiscord<iWonderAboutTuatara> how do I check?
19:37:07FromDiscord<Yardanico> Well anyway I can't answer now, sorry :)
19:37:11FromDiscord<iWonderAboutTuatara> no problem
19:37:20FromDiscord<iWonderAboutTuatara> @Rika using treerepr throws error
19:37:23*giannicozy quit (Remote host closed the connection)
19:37:36FromDiscord<Recruit_main707> have you imported macros¿
19:37:46FromDiscord<iWonderAboutTuatara> yep
19:37:51FromDiscord<iWonderAboutTuatara> I sent the nimgrounds link
19:37:58FromDiscord<iWonderAboutTuatara> https://play.nim-lang.org/#ix=2yXt\
19:38:42FromDiscord<Recruit_main707> what should it output?
19:39:01FromDiscord<iWonderAboutTuatara> it should already work
19:39:09FromDiscord<iWonderAboutTuatara> I'm just asking what the difference between oldidefs and idefs is
19:40:32FromDiscord<Rika> @iWonderAboutTuatara https://media.discordapp.net/attachments/371759389889003532/759862053628018718/unknown.png
19:41:15FromDiscord<iWonderAboutTuatara> how did you echo that?
19:41:44FromDiscord<Rika> `echo idefs.mapit(it.treerepr)`
19:41:55FromDiscord<iWonderAboutTuatara> oh I see
19:42:07FromDiscord<iWonderAboutTuatara> so what's happened here is that the identdefs is after the ident int node?
19:42:12FromDiscord<iWonderAboutTuatara> so the proc isn't given a return type?
19:44:23FromDiscord<Rika> proly
19:47:25*kenran quit (Ping timeout: 240 seconds)
19:52:44FromDiscord<iWonderAboutTuatara> I see
19:52:48FromDiscord<iWonderAboutTuatara> this is fun but very confusing
20:03:41FromDiscord<Yardanico> If you check what params of the proc should be and that newProc accepts openArray for params, it's not confusing :)
20:08:25FromDiscord<Yardanico> macros docs in the start show AST for most of possible Nim constructs
20:09:04FromDiscord<iWonderAboutTuatara> I think this is the kind of thing that you only really understand by doing
20:09:28FromDiscord<iWonderAboutTuatara> I have no experience with metaprogramming before this, so most of this AST manip concepts are new to me

21:45:31FromDiscord<Avatarfighter> Congrats everyone !
21:58:40FromDiscord<exelotl> Nice! :O
22:12:24FromDiscord<demotomohiro> Congratulations!
22:58:43FromDiscord<Avatarfighter> I really need to learn what the stuff in the Arraymancer library do because I'm incredibly curious to see what I can do but I'm so lost on where to start
23:07:06FromDiscord<Vindaar> what are you confused about?
23:07:20FromDiscord<Vindaar> Feel free to ask as many questions as necessary
23:09:51FromDiscord<Avatarfighter> I guess I'm confused about where I can start learning about wtf a tensor is and how do they allow for deep learning
23:10:19FromDiscord<Avatarfighter> I can write myself little programs with the arraymancer library I just don't understand why something does what it does lol
23:13:26FromDiscord<Vindaar> Hmm, well. How much math do you know or enjoy?
23:13:36FromDiscord<Avatarfighter> Oh gosh
23:14:16FromDiscord<Avatarfighter> Well I enjoy learning Math, I'm just pretty terrible at it lol
23:14:49FromDiscord<Avatarfighter> I'm still in high school so I wouldn't say that I know that much math when you think about math as a whole
23:15:28FromDiscord<Vindaar> Focus on the enjoy aspect. That you're bad at it is most likely just your view on yourself based on learning "math" in a rather bad way
23:15:56FromDiscord<Vindaar> If you're in high school I assume you know what a matrix is?
23:16:01FromDiscord<Avatarfighter> I do yes 🙂
23:17:16FromDiscord<Avatarfighter> tbh I am bad at math because of the way I was taught to take notes, I recently just switched the style for my notes and math is a whole new subject for me lmao
23:17:45FromDiscord<Vindaar> ok! In the simplest explanation a tensor as nothing but a generalization of the concept:↵scalar -> vector -> matrix -> ...↵Each can be thought of as a tensor of a certain rank
23:17:55FromDiscord<Vindaar> that's good to hear!
23:18:36FromDiscord<Vindaar> And tensors then allow you to have objects with higher rank ("higher dimensionality") essentially
23:19:18FromDiscord<Avatarfighter> Ohhh
23:19:25FromDiscord<Vindaar> e.g. a tensor of rank 3 is somewhat like a 3D matrix. Take a look here: https://en.wikipedia.org/wiki/Levi-Civita_symbol#/media/File:Epsilontensor.svg
23:21:27FromDiscord<Vindaar> well, technically the levi-civita symbol is _not_ a tensor, but that's precisely where tensors in computer science and maths typically lose their equivalence (a tensor is only specific kind of object, that transforms in a specific way under a coordinate transformations, which interestingly enough one of the main ingredients as to why general relativity is so hard mathematically, haha)
23:22:06FromDiscord<Vindaar> for CS you can really just think of a tensor as an N dimensional matrix
23:23:23FromDiscord<Avatarfighter> I'm doing more research into this
23:23:26FromDiscord<Avatarfighter> this is so cool!!
23:23:31FromDiscord<Vindaar> it is 🙂

23:25:32*ehmry joined #nim
23:25:36FromDiscord<Avatarfighter> Thanks for explanation Vindaar, I'm going to see if I can find an explanation on how ranking in nd-arrays work lol
23:25:43FromDiscord<Avatarfighter> n-dimensional arrays ig
23:25:53FromDiscord<Avatarfighter> or rather tensors(?)
23:26:49FromDiscord<Vindaar> well, that's the thing. I think many people just say nd-arrays to make it clearer that we aren't talking about mathematical tensors (at least not always)
23:28:11*mmohammadi98129 quit (Ping timeout: 258 seconds)
23:28:38FromDiscord<Vindaar> if you want to look at something, which is probably too crazy, but imo one of the best introductions to the math of tensors (from a practical point of view, it's not as rigorous as a mathematician might like), check out the beginning of Sean Carroll's notes on GR here:↵https://arxiv.org/pdf/gr-qc/9712019.pdf↵If you're anything like me seeing something like that might be inspiring 🙂
23:29:02FromDiscord<Vindaar> page 13 introduces tensors
23:29:30FromDiscord<Avatarfighter> I'll check it out 🙂 Wow this just puts into perspective how little I know about stuff and how hard it is for me to find information explained plainly on it.
23:30:15FromDiscord<Vindaar> I don't want to depress you, but... I feel the exact same to this day. I always though that feeling might disappear after studying physics. And it never did
23:30:41*abm quit (Read error: Connection reset by peer)
23:30:58FromDiscord<Vindaar> There's just too much stuff out there, that's too hard to grasp and only so little time... And as I mentioned, one forgets stuff too quickly, sigh
23:31:27FromDiscord<Avatarfighter> I run into this feeling quite a bit when doing "regular" programming lol
23:31:30FromDiscord<Vindaar> (doesn't mean I didn't learn _a lot_ and it wasn't worth it or something)
23:31:42FromDiscord<Vindaar> haha, happens to me too! 😄
23:33:04FromDiscord<Avatarfighter> I'm excited to get a higher education, I aspire to be at the point where I know the proper terms to search for on google sometimes its a bit awkward trying to find structures that are specialized when you don't actually know the name
23:33:40FromDiscord<Vindaar> oh yes, it really is. That's why education is worth so much. Helps with _knowing where to find stuff_
23:33:57FromDiscord<Avatarfighter> I think I spent a couple days learning that a Patricia tree is a thing lol
23:34:10FromDiscord<Vindaar> no idea what that is 🙃
23:34:19FromDiscord<Vindaar> oh a trie
23:34:23FromDiscord<Avatarfighter> Its a Radix tree
23:34:25FromDiscord<Avatarfighter> yeah
23:35:07FromDiscord<Avatarfighter> Its a really space efficient trie for strings that have common prefixes and I spent wayyy too long looking for the correct term
23:35:36FromDiscord<Vindaar> that's pretty cool
23:35:43FromDiscord<Vindaar> not the looking long part though
23:36:06FromDiscord<Avatarfighter> 🤷‍♂️ it is what it is
23:36:19FromDiscord<Vindaar> ok, anyways. I need to go to bed. ↵In case you have any mathy (programming related maybe) questions, feel free to ping me!
23:36:33FromDiscord<Avatarfighter> I will, thank you very much for the explanation and the help Vindaar 🙂
23:36:59FromDiscord<Vindaar> you're very welcome!
23:40:28FromDiscord<exelotl> woahh I understand what a tensor is now
23:41:22FromDiscord<Avatarfighter> right ?? lol
23:41:34FromDiscord<Avatarfighter> I thought it was something scary not a N-dimensional array
23:44:38FromDiscord<InventorMatt> i am trying to test out concepts and and I am getting an error even though the variable should pass all of the tests. any help to fix it or to know if it is impossible would be appreciated. https://play.nim-lang.org/#ix=2yYv
23:50:39FromDiscord<exelotl> @InventorMatt concepts are only able to express compile-time facts about a type, but here you're trying to use them to express runtime facts about an instance of that datatype
23:51:13FromDiscord<exelotl> (edit) 'that datatype' => 'a type'
23:51:27FromDiscord<InventorMatt> okay, that makes sense. thanks
23:52:34FromDiscord<exelotl> np :)
23:53:56FromDiscord<InventorMatt> is there a way to express runtime facts about an instance for a proc input. like for example only allowing unit vectors for the input?
23:56:05FromDiscord<exelotl> only with runtime checks, for example you could throw an exception if the magnitude is not approximately equal to 1
23:56:49FromDiscord<exelotl> but, if you know you're passing a constant value you can do compile time checks on it, I'll cook up an example
