| 00:01:19 | FromDiscord | <evoalg> nice! ... yea "hello" isn't a long string ... gosh i had to compile with "-d:release" and knock a zero off each of them just so it'd finish in a reasonable time on my system lol ... thank you for the nice example! |
| 00:01:46 | FromDiscord | <Elegantbeef> Well you should only bench on release or danger anywho |
| 00:02:01 | FromDiscord | <Elegantbeef> No problem for the example though |
| 00:06:21 | FromDiscord | <evoalg> That "full iter" one might even be slower when it has to do `a[i]` to actually use the values, or will it be just the same? |
| 00:06:47 | FromDiscord | <Elegantbeef> Oh right i forgot to index |
| 00:07:46 | FromDiscord | <Elegantbeef> It'll probably get inlined and not matter much |
| 00:08:45 | FromDiscord | <Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=3GiZ |
| 00:08:46 | FromDiscord | <Elegantbeef> Yea no cost |
| 00:09:06 | FromDiscord | <Elegantbeef> That std deviation of 20ns on the naive iteration is fucking silly |
| 00:09:16 | FromDiscord | <Elegantbeef> That's 50% of the average |

| 00:10:24 | FromDiscord | <Elegantbeef> what flags are you passing? |
| 00:10:31 | FromDiscord | <Elegantbeef> I'm doing `-d:release -d:lto` |
| 00:10:45 | FromDiscord | <evoalg> `nim -r -d:release c slicerator_test3.nim` |
| 00:10:49 | FromDiscord | <Recruit_main707> what was lto againg? |
| 00:10:49 | FromDiscord | <Elegantbeef> Though the `lto` doesnt matter too much |
| 00:10:56 | FromDiscord | <Elegantbeef> Link time optimization |
| 00:11:02 | FromDiscord | <Recruit_main707> thanks |
| 00:11:19 | FromDiscord | <Elegantbeef> it's preferable to use `--passC:"-flto" --passL:"-flto"` |
| 00:11:28 | FromDiscord | <Elegantbeef> Since that works on all compilers |
| 00:13:15 | FromDiscord | <evoalg> sent a code paste, see https://play.nim-lang.org/#ix=3Gj2 |
| 00:13:18 | FromDiscord | <ynfle (ynfle)> Why doesn't `-d:lto`? |
| 00:13:42 | FromDiscord | <Elegantbeef> Why dont do `-d:lto`? |
| 00:14:04 | FromDiscord | <Elegantbeef> It passes the wrong flags to clang and other C compilers |
| 00:14:05 | FromDiscord | <ynfle (ynfle)> Why doesn't it work on al compilers? |
| 00:14:19 | FromDiscord | <ynfle (ynfle)> Why can't it be configured to pass the correct ones? |
| 00:14:27 | FromDiscord | <Elegantbeef> It can but apparently no one bothered |
| 00:14:55 | FromDiscord | <Elegantbeef> Yea i dont know evo, quite odd performance numbers |
| 00:15:00 | FromDiscord | <Elegantbeef> Did you use a much bigger string? |
| 00:15:06 | FromDiscord | <Elegantbeef> Or is it still `"Hello"`? |
| 00:15:38 | FromDiscord | <evoalg> still "hello" ... but let me remind you that I'm running nim on linux with is on docker on my mac |
| 00:16:02 | FromDiscord | <Elegantbeef> Ah |
| 00:16:16 | FromDiscord | <evoalg> cos I'm cray cray |
| 00:16:24 | FromDiscord | <Elegantbeef> Apparently so |
| 00:16:31 | FromDiscord | <Elegantbeef> Takes 3 seconds to install Nim on mac 😛 |
| 00:19:12 | * | k0ta quit (Ping timeout: 260 seconds) |
| 00:20:10 | FromDiscord | <evoalg> it runs a lot faster! |
| 00:20:16 | FromDiscord | <evoalg> on my mac |
| 00:20:25 | FromDiscord | <Elegantbeef> Is the performance difference noticeable now? |

| 00:25:04 | FromDiscord | <Elegantbeef> Yay! |
| 00:25:15 | FromDiscord | <Elegantbeef> The deviation is unreal |
| 00:25:31 | FromDiscord | <evoalg> yea ... that's still with only "hello" |

| 00:32:39 | FromDiscord | <@MaskRay:matrix.org> Maybe... |

| 00:34:46 | FromDiscord | <Elegantbeef> Ah |
| 00:34:53 | * | vicecea quit (Remote host closed the connection) |
| 00:35:02 | FromDiscord | <Elegantbeef> I mean i'd be cautious using a ref in a pointer object, i dont know the validity there |
| 00:35:49 | * | vicecea joined #nim |
| 00:36:11 | FromDiscord | <Elegantbeef> This might be a bug, or this might be bad practice hard for me to reason |
| 00:37:05 | FromDiscord | <Elegantbeef> Hopefully someone smarter than i can weigh in |
| 00:38:22 | FromDiscord | <@MaskRay:matrix.org> Yeah, the usage looks suspicious. I'll just avoid the usage. Since I do manual memory management, I'll just avoid `ref` in the members |
| 00:41:32 | FromDiscord | <konsumlamm> in general, is there any performance difference between writing to a `var` parameter vs returning a new value? |
| 00:42:03 | FromDiscord | <Elegantbeef> Well there is supposed to be NVRO optimization but it can be buggy |
| 00:42:47 | FromDiscord | <Elegantbeef> NVRO should rewrite `proc(args): T` to `proc(args, ret: var T)` and pass the address of the variable in the case of `var a = doThing()` |
| 00:43:12 | FromDiscord | <Elegantbeef> https://nim-lang.org/docs/manual.html#procedures-nrvo |
| 00:43:12 | FromDiscord | <konsumlamm> oh, i've heard of NRVO a lot (mostly that it's not reliable), but i never bothered to look it up |
| 00:43:50 | FromDiscord | <Elegantbeef> Depends on the type of course on how bad it is if it fails, but yea if concerned just pass it |
| 00:43:54 | FromDiscord | <konsumlamm> so without NRVO, a `var` parameter would be more efficient because returning something would copy it? |
| 00:44:04 | FromDiscord | <Elegantbeef> Yep |
| 00:44:16 | FromDiscord | <Elegantbeef> It's only a concern with large data types |
| 00:44:27 | FromDiscord | <Elegantbeef> with small type it doesnt make much sense afaik |
| 00:44:41 | FromDiscord | <konsumlamm> i see, ty |
| 00:45:17 | FromDiscord | <Elegantbeef> Didnt know `If p can raise an exception, NRVO applies regardless. ` |
| 00:51:51 | * | k0ta joined #nim |
| 00:53:53 | FromDiscord | <evoalg> @ElegantBeef am I correct in thinking that slicing by allocation vs by iterator wont make any practical different for most programs? |
| 01:01:42 | FromDiscord | <Elegantbeef> Well slicing in a for statement creates a copy that is then destroyed by the memory management so indeed |
| 01:05:03 | FromDiscord | <evoalg> (Sorry it might have been a been cheeky for me to suggest that ... even though I don't find it satisfying that slices to that wasteful stuff, I'm wondering if it'll make any practical difference) |
| 01:05:09 | FromDiscord | <Elegantbeef> The only cases you want to keep the value around is when you're doing something like `var a = yourSeq[a..b]` and there is no semantic difference with the iterators |
| 01:05:47 | FromDiscord | <Elegantbeef> I mean it's a correct statement, the only difference is performance |
| 01:06:02 | FromDiscord | <Elegantbeef> Semantically the program will run the same using my iterators or using slices |
| 01:06:16 | FromDiscord | <evoalg> `var a = yourSeq[a..b]` <-- that works with an iterator? |
| 01:06:25 | FromDiscord | <Elegantbeef> Nope |
| 01:06:34 | FromDiscord | <Elegantbeef> That's the proc |
| 01:06:40 | FromDiscord | <evoalg> gotcha |
| 01:06:41 | FromDiscord | <Elegantbeef> iterators are only called in `for` statements or loops |
| 01:06:55 | FromDiscord | <evoalg> ahh ok! |
| 01:06:57 | FromDiscord | <Elegantbeef> i say or loops but i'm being daft |
| 01:07:23 | * | Onionhammer quit (Ping timeout: 256 seconds) |
| 01:08:22 | FromDiscord | <evoalg> I take it you don't like using `for i, x in ...` at any time ... how would you do that instead? ... `for i in ... ` and then just do `a[i]` etc? |
| 01:08:36 | FromDiscord | <Elegantbeef> The issue isnt `for i, x in ...` |
| 01:08:45 | FromDiscord | <Elegantbeef> The issue is the `yourCollection[a..b]` |
| 01:08:57 | FromDiscord | <Elegantbeef> without my package that's making a brand new collection |
| 01:09:03 | FromDiscord | <Elegantbeef> So it's very silly to do |
| 01:09:12 | * | Onionhammer joined #nim |
| 01:10:19 | FromDiscord | <evoalg> but ... but ... even before slicerator, I get the impression you'd avoid ever using `for i, x in` ? (yea I'm changing the subject a bit sorry) |
| 01:10:27 | FromDiscord | <Elegantbeef> No i dont |
| 01:10:38 | FromDiscord | <Elegantbeef> I like the pairs iterator very much |
| 01:10:53 | FromDiscord | <Elegantbeef> My disdain was with using slices + pairs |
| 01:11:36 | FromDiscord | <evoalg> ok phew! All clear now 🙂 |
| 01:12:22 | arkanoid | having big sad moments with nim <> python interop for science. We're far far from interop |
| 01:12:56 | FromDiscord | <Elegantbeef> The mechanism of `for i, x in coll[a..b]` is a lazy solution to the problem, but i'll give it's easy to do |
| 01:13:17 | FromDiscord | <Elegantbeef> cause you're slicing that collection then iterating over it, so it's doing twice the work |
| 01:13:34 | FromDiscord | <Elegantbeef> What's wrong with the interop? |
| 01:16:09 | arkanoid | passing strings from arraymancer to python (pandas/numpy) is not working |
| 01:16:25 | arkanoid | it's ok if you stay with numbers, but strings are just no |
| 01:16:55 | FromDiscord | <Elegantbeef> How is the interop beingn done? |
| 01:17:03 | FromDiscord | <Elegantbeef> being done even |
| 01:17:38 | arkanoid | arraymancer + datamancer + scinim/numpyarrays + nimpy |
| 01:18:03 | FromDiscord | <Elegantbeef> Nimpy should handle it |
| 01:18:07 | FromDiscord | <Elegantbeef> But odd that it doesnt |
| 01:18:54 | arkanoid | https://play.nim-lang.org/#ix=3Gjg |
| 01:19:04 | arkanoid | it won't run online |
| 01:20:04 | FromDiscord | <Elegantbeef> Jeez i'm going to be testing code that talks to python, what have i done to deserve this |
| 01:21:50 | arkanoid | I'm trying escape python too |
| 01:22:24 | arkanoid | but I need to move data for this |
| 01:22:37 | FromDiscord | <Elegantbeef> I dont try to escape it |
| 01:22:40 | FromDiscord | <Elegantbeef> I never visited 😛 |
| 01:23:56 | arkanoid | got captured from it due to data science, sadly it has very good tools |
| 01:25:24 | arkanoid | this is how toNdArray is supposed to be used to move data from nim to python: https://scinim.github.io/getting-started/external_language_integration/nim_with_py.html |
| 01:26:29 | FromDiscord | <Elegantbeef> it errors for you on the `toNdArray`? |
| 01:27:03 | arkanoid | yes, it returns a Error: type mismatch |
| 01:27:16 | arkanoid | numpyarrays.nim(179, 37) |
| 01:28:22 | FromDiscord | <Elegantbeef> Seems it's 100% just a string tensor isnt happened |
| 01:28:26 | FromDiscord | <Elegantbeef> handled |
| 01:28:29 | FromDiscord | <Elegantbeef> Jeez i cannot type |
| 01:28:47 | arkanoid | this is the error I get: https://play.nim-lang.org/#ix=3Gjj |
| 01:28:57 | FromDiscord | <Elegantbeef> Yea same error |
| 01:29:22 | arkanoid | exactly. Without the possibility to send a string Tensor to python, no party for science |
| 01:29:54 | arkanoid | actually I'm quite confused if I do really need to use scinim/numpyarrays |
| 01:30:48 | arkanoid | by lurking the arraymancer issues it seems that there a thing called "laser" already merged supposed to make this operation possible, but unsure |
| 01:32:19 | FromDiscord | <Elegantbeef> Well `KnownSupportsCopyMem` is the issue |
| 01:32:32 | FromDiscord | <Elegantbeef> I dont know where it's declared |
| 01:32:55 | FromDiscord | <Elegantbeef> Ah it's in arraymancer |
| 01:33:31 | FromDiscord | <Elegantbeef> https://github.com/mratsim/Arraymancer/blob/66372d249b849102fd196345a08d4563d904751a/src/arraymancer/laser/tensor/datatypes.nim#L17 either string needs to be added here and handled, or a new overload that accepts `Tensor[string]` needs to be implemented |
| 01:33:33 | arkanoid | I think the real issue is this. Try "let data = @[@["a","b","c"],@["d","e","f"]].toTensor.get_data_ptr" |
| 01:34:03 | FromDiscord | <Elegantbeef> It's calling `toUnsafeView` on the tensor and not getting one cause it's not handled for this type |
| 01:34:31 | arkanoid | maybe because strings does not support copymem? |
| 01:34:52 | FromDiscord | <Elegantbeef> Well they do just not directly |
| 01:35:40 | FromDiscord | <Elegantbeef> https://github.com/mratsim/Arraymancer/blob/66372d249b849102fd196345a08d4563d904751a/src/arraymancer/laser/tensor/initialization.nim#L259 implementing this for a string is probably the only solution |
| 01:36:08 | FromDiscord | <Elegantbeef> should be `cast[ptr UncheckedArray[char](yourString[0].unsafeAddr)` though dont know the downside |
| 01:36:34 | FromDiscord | <Elegantbeef> I very much dont know about it |
| 01:37:09 | arkanoid | I'll just consider nim+python integration not possible when dealing with a dataframe with a string column |
| 01:37:25 | FromDiscord | <Elegantbeef> I think it's fully doable just it'll require copying data |
| 01:39:28 | arkanoid | sure I'm not planning to share GC'ed stuff between the two worlds |
| 01:39:47 | arkanoid | but how to copy/interop with strings is not documented |
| 01:47:50 | arkanoid | sigh, every time I try to start a new project with nim instead of python, I have to walk back to that old dirty road. Sad. Hopefully I will be able to write some nim functions and export them with exportpy |
| 01:48:26 | arkanoid | thanks for the help Elegantbeef |
| 01:49:37 | FromDiscord | <JOSTGRANT> On the topic of Python vs Nim; Is there a rough equivalent to "Wheels" floating around? |
| 01:51:55 | arkanoid | this money went to numpy, scipy, matplotlib and pandas: https://chanzuckerberg.com/newsroom/czi-awards-16-million-for-foundational-open-source-software-tools-essential-to-biomedicine/ . Nim is just better for everything, it just lacks libs and users |
| 01:52:27 | arkanoid | JOSTGRANT, what do you mean? Why you want wheels? |
| 01:53:40 | FromDiscord | <JOSTGRANT> To make it trivial to install C/C++ level dependencies for Nim packages in Nimble. Maybe this is already possible and I just haven't looked deep enough though :^P |
| 01:56:02 | arkanoid | All files and folders in the directory where the .nimble file resides will be copied as-is |
| 01:56:27 | arkanoid | you can however skip some directories or files by setting the skipDirs, skipFiles or skipExt options in your .nimble file. Directories and files can also be specified on a whitelist basis, if you specify either of installDirs, installFiles or installExt then Nimble will only install the files specified |
| 01:56:39 | arkanoid | I'm just copypasting from https://github.com/nim-lang/nimble |
| 01:57:36 | FromDiscord | <JOSTGRANT> Is that how Wheels works? I have no idea, I assumed it was grabbing offsite and there was just some config you specified or something? Have only been an end-user of it -- not done any of the actual grunt-work to make it happen |
| 01:59:58 | arkanoid | The *.whl file is similar to an *.egg in that it’s basically a *.zip file in disguise. If you rename the extension from *.whl to *.zip, you can open it up with your zip application of choice and examine the files and folders inside at your leisure |
| 02:01:04 | FromDiscord | <JOSTGRANT> So it's all just prepackaged then (underlying C/C++ dependencies). Fair enough. So wonder if this is just not done as-often currently in Nim because it'd bloat a given package / archive? |
| 02:02:01 | arkanoid | there's a setup file to do stuff |
| 02:02:52 | arkanoid | have to go now, sorry, it's damn cold here |
| 02:03:32 | FromDiscord | <JOSTGRANT> arkanoid: np thanks for the clarification! |
| 02:03:46 | arkanoid | yw |
| 02:04:39 | FromDiscord | <JOSTGRANT> _will also def look into it more. Guess it should be trivial for what I've been messing with recently (namely raylib demos ... could just add the given headers to my repo for now I guess anyways)._ |

| 02:52:43 | FromDiscord | <Elegantbeef> Here is a macro approach https://play.nim-lang.org/#ix=3Gjw |
| 02:52:57 | FromDiscord | <Elegantbeef> Only works for this specific object and relation ship so something can very easily fuck it up i imagine |

| 02:58:52 | FromDiscord | <Anonymous Poet> sent a code paste, see https://play.nim-lang.org/#ix=3Gjy |
| 03:00:48 | FromDiscord | <Anonymous Poet> supposing i know that the structure always follows this pattern (each case only has a single member, with the matching name + type), and we can assume that i can read the correct object; but i need to parse the enum type to know what to read and then cast to the right variant |
| 03:01:35 | FromDiscord | <Elegantbeef> https://play.nim-lang.org/#ix=3GjF |
| 03:01:41 | FromDiscord | <Elegantbeef> The macro does work if this is the pattern you have |
| 03:02:34 | FromDiscord | <Elegantbeef> Also if it's `kind` is root level on all objects you can do anothing thing |
| 03:02:47 | FromDiscord | <Anonymous Poet> why is the returned object of type `EquipmentKind` instead of `Equipment`? |
| 03:02:59 | FromDiscord | <Anonymous Poet> yes, kind is root level; what do you have in mind? |
| 03:03:39 | FromDiscord | <Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=3GjG |
| 03:04:09 | FromDiscord | <Anonymous Poet> still prints the same thing :/ |
| 03:04:28 | FromDiscord | <Elegantbeef> What's the expected output? |
| 03:04:51 | FromDiscord | <Anonymous Poet> `Equipment`, ie. `get` is supposed to return an object of type T |
| 03:05:01 | FromDiscord | <Elegantbeef> It does |
| 03:05:04 | FromDiscord | <Anonymous Poet> actually im very confused why this is printing the wrong thing |
| 03:05:12 | FromDiscord | <Anonymous Poet> is this the overloaded $? |
| 03:05:32 | FromDiscord | <Anonymous Poet> yup, i was just being dumb |
| 03:06:04 | FromDiscord | <Anonymous Poet> out of curiosity, does the line↵`typeof(T().kind)` actually allocate anything? or is the compiler smart enough to know i just want the type? |
| 03:06:10 | FromDiscord | <Elegantbeef> and no `typeof(T().kind)` is not done at runtiime |
| 03:06:34 | FromDiscord | <Elegantbeef> `typeof` gets the type of an expression so has to be done statically which means compile time |
| 03:08:00 | FromDiscord | <Anonymous Poet> thanks, i think this is close to what i had in mind; let me play around with it a bit. next issue is going to be creating an object of the matching variant |
| 03:26:38 | FromDiscord | <Anonymous Poet> ok, so i did get to the next issue now |
| 03:26:40 | FromDiscord | <impbox [ftsf]> looking at using https://github.com/nim-lang/dialogs i'm wondering if there's a way I can open a dialog but not block my app while it's open? |
| 03:28:36 | FromDiscord | <Anonymous Poet> In reply to @impbox "looking at using https://github.com/nim-lang/dialog": not familiar with this lib, but when you say "block my app" do you mean the app freezes, or that you cant access the content behind the dialog? the second one seems intended, and the first you might need to work around by having a different thread for rendering and working/processing |
| 03:29:51 | FromDiscord | <impbox [ftsf]> the app freezes, I'd like the dialog to run separately and I guess notify my app when a selection has been made |
| 03:30:03 | FromDiscord | <impbox [ftsf]> maybe I can use a separate process |
| 03:30:08 | FromDiscord | <impbox [ftsf]> or threads |
| 03:30:20 | FromDiscord | <Elegantbeef> Yea the easy answer is throw up a thread |
| 03:30:46 | FromDiscord | <Elegantbeef> A thread shouldnt be too bad |
| 03:31:45 | FromDiscord | <Elegantbeef> I atleast assume you're after the `info`/`warning` dialogs? |
| 03:34:12 | FromDiscord | <impbox [ftsf]> nah, open file |
| 03:34:30 | FromDiscord | <impbox [ftsf]> it's for a live music visualiser, so i don't it to pause the show when i want to load in a new file |

| 03:42:49 | FromDiscord | <Elegantbeef> Well you've got a runtime value you want to convert to a type |
| 03:42:49 | FromDiscord | <Elegantbeef> It's not static |
| 03:43:01 | FromDiscord | <Anonymous Poet> this is meant to run at compiletime |
| 03:43:05 | FromDiscord | <Elegantbeef> If that was a `const` it is doable |
| 03:43:09 | FromDiscord | <Elegantbeef> Oh then yes it's doable |
| 03:43:38 | FromDiscord | <Elegantbeef> Though pretty pointless, but i'll show how |
| 03:43:40 | FromDiscord | <Anonymous Poet> its not quite const though; im parsing a schema file and generating the types from that |
| 03:44:01 | FromDiscord | <Elegantbeef> Well if it's done at compile time should be fine |
| 03:44:03 | FromDiscord | <Anonymous Poet> why do you say it is pointless? i might be missing something in that case |
| 03:44:25 | FromDiscord | <Elegantbeef> depends on what you're doing i suppose |
| 03:45:13 | FromDiscord | <Anonymous Poet> i have a schema file and a binary buffer created by that schema; im trying to write a codegen lib that will create the code to parse buffers specified by the given schema |
| 03:45:28 | FromDiscord | <Anonymous Poet> we can assume the schema is known at compile time |
| 03:46:06 | FromDiscord | <Anonymous Poet> ive implemented everything except the variant types that the schema allows |
| 03:47:45 | FromDiscord | <Elegantbeef> It might be doable, depends on how you skin it |
| 03:47:49 | FromDiscord | <Anonymous Poet> i think the way im trying to implement this may or may not be quite right though |
| 03:47:53 | FromDiscord | <Elegantbeef> You're probably better passing it to macro |
| 03:48:22 | FromDiscord | <Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=3GjY |
| 03:48:33 | FromDiscord | <Anonymous Poet> in the case of this `get` function, we can assume that the type exists, but is not in scope of this file |
| 03:49:30 | FromDiscord | <Elegantbeef> Can i see the scheme? |
| 03:49:58 | FromDiscord | <Anonymous Poet> i can give an example schema, but it changes, hence the code gen :p |
| 03:50:09 | FromDiscord | <Anonymous Poet> specifically, im trying to write a flatbuffer compiler |
| 03:50:51 | FromDiscord | <Anonymous Poet> sent a code paste, see https://play.nim-lang.org/#ix=3GjZ |
| 03:52:16 | FromDiscord | <Elegantbeef> I dont know much about flat buffers, but i dont know if this is the right way around |
| 03:52:16 | FromDiscord | <Anonymous Poet> im imagining that the code im writing would be compiled by the end user together with their schema, and would generate some nim files that their project would import to read the data from the schema |
| 03:53:08 | FromDiscord | <Elegantbeef> the way i see it you have a variety of types you tag/id that can be used with a flat buffer then when you store the types it writes `id, data, id, data` ... so then you can access it directly |
| 03:53:34 | FromDiscord | <Elegantbeef> But it only works for static sized types afaik |
| 03:53:41 | FromDiscord | <Elegantbeef> Like i said i dont know anything about it, so probably should shush |
| 03:55:10 | FromDiscord | <Anonymous Poet> thats not quite correct; because the schema is agreed upon out-of-band, you dont have the same static sized type requirements |
| 03:55:30 | FromDiscord | <Elegantbeef> Isnt the entire point of it so you dont have to unpack values |
| 03:55:32 | FromDiscord | <Anonymous Poet> there are still some restrictions (like on alignment, etc), but i dont think thats relevant |
| 03:56:23 | FromDiscord | <Anonymous Poet> i think the point is more that you dont need to deserialize the whole buffer, if youre looking for a specific entry, you can follow a short number of pointer derefs to get what you want |
| 03:57:01 | FromDiscord | <Anonymous Poet> so if i know that my root type is Monster, and given a buffer i want Monster.Pos.Z, i dont need to read the whole buffer and parse it |
| 03:57:05 | FromDiscord | <Elegantbeef> yea i dont know anything about it, from briefly reading i figured you just have your structs stored with an ID so you can access fields |
| 03:58:02 | FromDiscord | <Anonymous Poet> the format is fairly simple though not as well documented as id like, haha :/ structs are just stored as dumps of data, tables are a bit more complex |
| 03:58:23 | FromDiscord | <Anonymous Poet> in any case though, i can read all of the basic types just fine, and mostly do the generic code generation that i want |
| 03:58:52 | FromDiscord | <Anonymous Poet> the problem (and maybe this is a design flaw on my part) is for the unions, i need to read the type (thats fine) and then return an object of the matching type |
| 03:59:18 | FromDiscord | <Anonymous Poet> i can do this, but i dont know how to express the return object construction bit |
| 03:59:34 | FromDiscord | <Elegantbeef> I can only say look at serialization libraries |
| 04:00:37 | FromDiscord | <Anonymous Poet> hmm, not sure that will really help for this; do you have any recommendations for resources on generics in nim? and macros? |
| 04:01:25 | FromDiscord | <Elegantbeef> https://dev.to/beef331/demystification-of-macros-in-nim-13n8 is all i really have for macros generics are simple so i dont think you overly need manuals for them 😀 |
| 04:01:48 | FromDiscord | <Anonymous Poet> i guess i meant "generics in macros" 😄 thanks |

| 04:15:21 | meowray | How to emulate a dynamic_cast with a `template`? Like C++ `if (auto *maybe_sub = dynamic_cast<Sub>(x))` |
| 04:16:23 | FromDiscord | <Elegantbeef> dynamic cast is a conversion to an inherited type? |
| 04:16:58 | FromDiscord | <Anonymous Poet> dynamic cast tries to convert to a parent type |
| 04:17:22 | FromDiscord | <Elegantbeef> Should just be `ParentType(yourType)` |
| 04:17:46 | FromDiscord | <Anonymous Poet> dynamic cast is runtime though; not sure how you can do the conditional like this |
| 04:18:06 | FromDiscord | <Anonymous Poet> and sorry, not parent, child type |
| 04:18:10 | FromDiscord | <Elegantbeef> `if yourType of SpecificType` |
| 04:22:50 | FromDiscord | <Elegantbeef> hopefully that suffices meow |
| 04:23:10 | FromDiscord | <Elegantbeef> actually that should be `yourVal` 😛 |

| 04:32:22 | FromDiscord | <Elegantbeef> Well it's not correct as much as an option |
| 04:33:07 | FromDiscord | <Elegantbeef> You may want to look at using type aliases or making your own create that handles this better so you dont need `ptr T` everywhere |
| 04:34:28 | FromDiscord | <Elegantbeef> That is assuming you are mostly doing `ptr T` |

| 04:39:08 | FromDiscord | <Elegantbeef> I mean it can be typed i was being lazy |
| 05:07:27 | FromDiscord | <@MaskRay:matrix.org> Nice. How do I use object construction syntax with `ptr object`? I.e. I want to initialize `someField` when creating `ChildA` |
| 05:09:50 | FromDiscord | <Elegantbeef> `a[] = typeof(a[])(someField: 30)` it's not ergonomic one bit |

| 05:14:00 | FromDiscord | <Marisol> Hey guys, does norm has automatic created_at and updated_at support? Or need to implement manually for every model? |
| 05:19:42 | FromDiscord | <@MaskRay:matrix.org> Then I'll stick with `object` instead of `ptr object` so that I can use `create`. I am using `ptr` for the main data structure (Section, Symbol) and `ref` for objects with few instances (linker script command) because `ref` has better ergonomics. I guess I am abusing https://nim-lang.org/docs/manual.html#types-mixing-gc-ed-memory-with-nimptr hope I don't run into weird issues... |

| 10:01:52 | FromDiscord | <Rika> Are you running on the terminal |
| 10:02:00 | FromDiscord | <Rika> Is the terminal in the same directory |
| 10:02:32 | FromDiscord | <DaiChimpo> I have another similar program in a parent directory that works, but that's an interesting theory. Lemme try absolute path then |
| 10:05:04 | FromDiscord | <DaiChimpo> ok fair point absolute path works. Terminal is on a separate drive (haha) but program in E:\X\Y works when this in E:\X\A\B\C doesn't. This is for morning me probably |
| 10:07:32 | FromDiscord | <DaiChimpo> god damn it it's because the filename is relative to the terminal's working directory and not the .nim file's directory, I am going to bed |
| 10:08:13 | FromDiscord | <Elegantbeef> `import std/os; setCurrentDir(getAppDir())` 😛 |

| 10:56:43 | FromDiscord | <enthus1ast> Prepend |
| 10:58:29 | FromDiscord | <enthus1ast> Imho changing the working dir is an antipattern |
| 11:01:47 | FromDiscord | <Rika> Why |
| 11:05:23 | FromDiscord | <enthus1ast> at least in shellscripts its bad because it changes the terminals work dir |
| 11:05:32 | FromDiscord | <enthus1ast> unless you run it in a subshell |
| 11:06:05 | FromDiscord | <enthus1ast> just tried it with nim and does not change the outer work dir |
| 11:06:16 | FromDiscord | <enthus1ast> so maybe not that bad \:) |

| 14:48:20 | FromDiscord | <Rika> templates cant return |
| 14:48:42 | FromDiscord | <Rika> dont put return there and instead rely on implicit value return |
| 14:49:07 | FromDiscord | <lenis> ah yeah thats right |
| 14:49:12 | FromDiscord | <Rika> copy paste = return is copied = proc now returns what template was supposed to return |
| 14:49:18 | FromDiscord | <Rika> = type error |

| 15:00:20 | FromDiscord | <lenis> you might also have to add {.inject.} im not certain |
| 15:00:52 | FromDiscord | <gdquest> Is there a code formatter or options to have something a bit more like Python's black for Nim? In particular, I'm looking for something that tidies up line returns between procs, things like those |
| 15:01:10 | FromDiscord | <gdquest> I like to use opinionated formatters that just format about everything for you |
| 15:01:37 | FromDiscord | <gdquest> E.g. `black` will ensure there are always 2 lines between functions and classes in Python |
| 15:03:04 | FromDiscord | <qb> `nimpretty` ? |
| 15:03:40 | FromDiscord | <Rika> nimpretty is opinionated |
| 15:03:52 | FromDiscord | <gdquest> I use it, sure, but it doesn't do the above |
| 15:04:10 | FromDiscord | <Rika> i was planning on making a stronger formatter but i did not have the time |
| 15:04:16 | FromDiscord | <Rika> or rather still do not |
| 15:04:16 | FromDiscord | <qb> aww |
| 15:04:42 | FromDiscord | <gdquest> A formatter in Nim seems pretty fun to make as you have the whole AST, |
| 15:04:50 | FromDiscord | <gdquest> But it's always quite a bit of work |
| 15:05:18 | FromDiscord | <Rika> well you'll need to find out where to get the parser (prolly compiler-as-a-package but i dont know the status of that) |
| 15:05:31 | FromDiscord | <gdquest> Ah okay |
| 15:06:22 | FromDiscord | <gdquest> I'm not fond of how nimpretty does line returns either, it tries to keep things packed vertically and doesn't favor making things easier to read I feel |

| 15:08:21 | FromDiscord | <Rika> sent a code paste, see https://play.nim-lang.org/#ix=3Gnt |
| 15:08:35 | FromDiscord | <Rika> which is why i was planning on making a flexible one (prolly more akin to clang-format) |
| 15:09:25 | FromDiscord | <gdquest> Yeah so to me opinionated should be non-configurable, but driven by UX design work |
| 15:09:40 | FromDiscord | <gdquest> That is, gathering data on what people find most readable and formatting like that |
| 15:10:18 | FromDiscord | <gdquest> I doubt that's how nimpretty was developed, that is, gathering quantitative feedback and doing A/B testing with many users |
| 15:10:38 | FromDiscord | <gdquest> Which is fine, it's still a useful tool |
| 15:11:15 | FromDiscord | <gdquest> It's just that it simply splits lines longer than 80 character after an operator. It's a sound, simple rule programming-wise |
| 15:11:38 | FromDiscord | <gdquest> But it doesn't optimize for what's easiest to read for most people |
| 15:12:05 | FromDiscord | <gdquest> Nimpretty will let you split lines however you want too, if you want to do it manually instead |
| 15:12:38 | FromDiscord | <gdquest> Anyway, thanks much once again. |
| 15:13:04 | FromDiscord | <gdquest> (edit) "Nimpretty will ... let-" added "also" | "alsolet you split lines however you want too, if you want to do it manually instead ... " added "- it just checks the line length" |
| 15:13:15 | FromDiscord | <gdquest> (edit) "Nimpretty will also let you split ... lines" added "and format" |
| 15:14:08 | FromDiscord | <Rika> In reply to @gdquest "Yeah so to me": well i want it to be configurable, but the defaults are also good |

| 15:36:25 | FromDiscord | <Rika> technically cant (unless you mean what i think you mean) because fields is a compiletime iterator and whichever fields actually are part is dependent on runtime info |
| 15:38:08 | Bager170 | couldn't you expand it to a case statement? |
| 15:38:58 | Bager170 | like you put all the fields of one object variant into one case statement branch and same for the other one |
| 15:39:56 | Bager170 | or am i wrong in thinking that the fields iterator acts like a macro? |
| 15:40:18 | FromDiscord | <Rika> im thinking about it |
| 15:40:49 | FromDiscord | <Rika> it could probably work but that would be a large possibly breaking change i'd assume |
| 15:41:03 | FromDiscord | <Rika> or new edge case issues |

| 16:06:47 | FromDiscord | <hmmm> oioi I need to parse an xml file and get out all the contents between a tag. Since there are many I also want all the matches placed on a seq. What should I use? |
| 16:07:11 | FromDiscord | <Rika> xmltree? |
| 16:07:21 | FromDiscord | <hmmm> sounds right |
| 16:07:25 | FromDiscord | <hmmm> I'll look into it |

| 16:08:53 | FromDiscord | <Rika> afaik at least |
| 16:09:09 | FromDiscord | <Rika> prolly something's there but i would call it "hacky" |
| 16:09:19 | FromDiscord | <Rika> maybe something to do with line instantiation info |

| 17:02:21 | FromDiscord | <hmmm> I remember using it in the past but forgot all about it lol |
| 17:04:55 | FromDiscord | <Rika> In reply to @TryAngle "is there something like": no |
| 17:05:17 | FromDiscord | <Rika> In reply to @hmmm "I remember using it": i dont recall such a thing being in the standard library' |
| 17:06:31 | FromDiscord | <qb> Something like that was in the template documentation https://nim-lang.org/docs/tut2.html#templates |
| 17:07:14 | FromDiscord | <Rika> i dont think its recommended anymore though as destructors are slowly being introduced |

| 17:11:26 | FromDiscord | <hmmm> I see a string example 🤨 |
| 17:12:08 | Amun-Ra | it works closely to Pascal's with equivalent |
| 17:12:22 | Amun-Ra | and it's a different beast than Python one |

| 17:21:26 | FromDiscord | <Rika> ~~god damn thats a real hard to read font~~ |
| 17:21:36 | FromDiscord | <JOSTGRANT> Think I'm 'remembered' / recall a similarity with the yellow for keywords, and orange in Ayu, green strings, and purple being present. |
| 17:21:57 | FromDiscord | <Rika> ah yes yellow and orange my worst nightmare |
| 17:23:34 | FromDiscord | <JOSTGRANT> Should be 'droid sans mono'; Though I'm not really font-picky unless it's REALLY out there. lol |
| 17:23:53 | FromDiscord | <Rika> it's just too thin for me |
| 17:24:32 | FromDiscord | <JOSTGRANT> "Thin" as-in not enough spacing between characters, or the actual characters themselves are too thin? |
| 17:24:52 | FromDiscord | <Rika> latter |
| 17:25:34 | FromDiscord | <JOSTGRANT> It's honestly something I don't even consciously notice; Now that I'm looking can see it between numerals though I guess. |
| 17:25:55 | FromDiscord | <Rika> i notice because i read much more erratically lmao |
| 17:26:01 | FromDiscord | <Rika> or slowly |
| 17:26:36 | FromDiscord | <JOSTGRANT> For me, I feel like color-themes are more important than most fonts tbh. But very possibly I'm "the weird one". lol |
| 17:26:56 | FromDiscord | <Rika> oh colour matters a lot too but font thickness isnt negligible |
| 17:28:26 | FromDiscord | <JOSTGRANT> I guess they (fonts) are just easier to 'not notice' consciously ; When a bad 'theme' can result in actual revulsion |
| 17:28:47 | FromDiscord | <Rika> ~~me swearing by my solarized~~ |
| 17:31:02 | FromDiscord | <JOSTGRANT> I've jumped all around; When I was still on Emacs I wrote a custom light and dark theme and was pretty happy with them -- then switched to Atom then eventually VSCode an about a dozen-or-so themes in that transitionally period and at somepoint @lqdev either recommended and/or just posted screenshots in this server about Ayu and have been on 'Ayu Mirage' ever since. |
| 17:31:25 | FromDiscord | <JOSTGRANT> (edit) "an" => "and" |
| 17:32:15 | FromDiscord | <Rika> i use solarized because i can actually see the differences between colours without taking idk 3 seconds to compare |
| 17:32:47 | FromDiscord | <JOSTGRANT> Yeah, not a huge fan of Solarized but am 100% with them in the goal of highly contrasted themes are the ideal |
| 17:33:56 | FromDiscord | <TryAngle> In reply to @Rika "no": ok ty |
| 17:34:12 | FromDiscord | <JOSTGRANT> Well I guess solarized isn't "highly contrasting" tbf but the hues are notable enough to 'not be a problem' |
| 17:34:18 | FromDiscord | <Rika> In reply to @TryAngle "ok ty": i mean there probably is in some macro beef made but L O L |
| 17:34:25 | FromDiscord | <Rika> not something for prod i'd say |
| 17:34:41 | FromDiscord | <Rika> In reply to @JOSTGRANT "Well I guess solarized": its been a massive help yes |
| 17:35:44 | FromDiscord | <JOSTGRANT> I think Ayu Mirage fits into a similar niche; There's not an extreme amount of 'pop' compared to the bg but it's certainly more than enough to easily tell apart elements |
| 17:36:14 | FromDiscord | <JOSTGRANT> It doesn't feel like everything is a "shade of grey" which seems pretty common in theme design. lol |
| 17:38:54 | FromDiscord | <TryAngle> In reply to @Rika "i mean there probably": ah true I forgot that you can almost write your own language in nim XD |
| 17:40:58 | FromDiscord | <TryAngle> what is a lent? https://media.discordapp.net/attachments/371759389889003532/914571579634102332/unknown.png |

| 18:18:21 | FromDiscord | <hmmm> Rika I actually wrote a while loop to chunk stuff around. I feel it's so solid it could blaze into our std |
| 18:23:48 | Guest19 | Looks like the Nim package is unmaintained? https://src.fedoraproject.org/rpms/nim |
| 18:31:01 | FromDiscord | <hmmm> hmm |

| 18:34:18 | FromDiscord | <apahl> In reply to @Guest19 "Looks like the Nim": IMO, the easiest way to install Nim on Linux and to keep it up to date, is to clone the repo and run `./build_all.sh` (https://github.com/nim-lang/Nim/#compiling) |
| 18:34:37 | nrds | <Prestige99> or just use choosenim |
| 18:36:00 | nrds | <Prestige99> I think that easiest |

| 23:41:08 | FromDiscord | <Elegantbeef> That just means you dont have `{.base.}` applied to the method, which you do |
| 23:41:22 | FromDiscord | <Elegantbeef> So i can only imagine you're using an older nim version since it doesnt appear on 1.6.0 |
| 23:41:33 | FromDiscord | <Phytolizer> using 1.7.1 |
| 23:43:21 | FromDiscord | <Phytolizer> do you think it is just a bug in nimlsp? it does compile with nim |
| 23:43:47 | FromDiscord | <Phytolizer> using nimlsp 0.3.2 |
| 23:45:03 | FromDiscord | <Elegantbeef> Quite possibly |
| 23:45:24 | FromDiscord | <Elegantbeef> Does `nim check` print any errors? |
