| 01:13:52 | FromDiscord | <huantian> When using jsony to parse json into an object, is there a way to do something special with a certain field of that one specific type |
| 01:15:17 | FromDiscord | <Elegantbeef> write a json hook for that object then do something special for that field |
| 01:22:21 | FromDiscord | <huantian> would I then have to implement the rest of the parsing myself? |
| 01:22:38 | FromDiscord | <huantian> or is there a way to borrow it |
| 01:23:07 | FromDiscord | <Elegantbeef> You can just call the hook manually, or atleast should be able to |
| 01:24:07 | FromDiscord | <huantian> then it turns into a recursive function since the overload matches the more specific hook that I'm definig |
| 01:24:16 | FromDiscord | <huantian> at least that's what I think it does |
| 01:25:26 | FromDiscord | <Elegantbeef> What's your code? |
| 01:26:32 | FromDiscord | <huantian> sent a code paste, see https://play.nim-lang.org/#ix=3R7Z |
| 01:26:55 | FromDiscord | <Elegantbeef> Well yea who said to call this object's proc?! |
| 01:27:56 | FromDiscord | <Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=3R80 |
| 01:29:53 | FromDiscord | <huantian> ah that makes a lot more sense |
| 01:30:06 | FromDiscord | <huantian> thanks 🙏 |
| 01:30:24 | FromDiscord | <Elegantbeef> Personally i'd say to make a distinct type for the field |
| 01:30:32 | FromDiscord | <Elegantbeef> This way you dont need your own hook for the object |
| 01:32:12 | FromDiscord | <Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=3R81 |
| 01:57:11 | FromDiscord | <kalbhairab> Can we include units of measure in nim |
| 01:57:25 | FromDiscord | <Rika> sure why not |
| 01:57:32 | FromDiscord | <Rika> what do you mean exactly though |
| 01:57:44 | FromDiscord | <kalbhairab> See fsharp |
| 01:57:50 | FromDiscord | <kalbhairab> Units of measure |
| 01:57:51 | FromDiscord | <Elegantbeef> https://github.com/SciNim/Measuremancer#other-distinct-data-types |
| 01:58:26 | FromDiscord | <Rika> does it have nonunicode ops too? |
| 01:58:37 | FromDiscord | <Elegantbeef> Sorry it's unchained https://github.com/SciNim/Unchained |
| 01:59:31 | FromDiscord | <ynfle> Great and mind boggling implementation |
| 01:59:36 | FromDiscord | <Rika> mind boggling? |
| 01:59:37 | FromDiscord | <ynfle> (edit) "Great ... and" added "library" |
| 01:59:58 | FromDiscord | <ynfle> Have you taken a look at the implementation? |
| 02:00:01 | FromDiscord | <kalbhairab> Very great than fsharp |
| 02:04:00 | FromDiscord | <kalbhairab> Strformat should be core library |
| 02:04:33 | FromDiscord | <Rika> ? it is part of the stdlib |
| 02:04:43 | FromDiscord | <Elegantbeef> I think they mean it should be auto imported |
| 02:04:53 | FromDiscord | <Elegantbeef> Which i say, you can always add that to your project config, or your global config |
| 02:05:02 | FromDiscord | <Elegantbeef> The latter is going to be more error prone |
| 02:05:11 | FromDiscord | <kalbhairab> Yes |
| 02:05:19 | FromDiscord | <kalbhairab> I am saying that |
| 02:05:26 | FromDiscord | <kalbhairab> Auto imported |
| 02:05:42 | FromDiscord | <Elegantbeef> The core nim devs presently think the system library is to big, so it's going to get smaller in time |
| 02:05:54 | FromDiscord | <Elegantbeef> Modules exist and should be used |
| 02:06:04 | FromDiscord | <kalbhairab> "{person.name} is " |
| 02:06:07 | FromDiscord | <Elegantbeef> Just cause it's easier to auto import doesnt mean it should be |
| 02:06:14 | FromDiscord | <kalbhairab> Ohh |
| 02:06:17 | FromDiscord | <kalbhairab> Why |
| 02:06:50 | FromDiscord | <Elegantbeef> Cause it pollutes the namespace, and it fails to follow proper module conventions |
| 02:07:01 | FromDiscord | <Elegantbeef> You the modules you need, all modules available |
| 02:07:03 | FromDiscord | <Rika> it doesnt really pollute the namespace here |
| 02:07:08 | FromDiscord | <Elegantbeef> not all modules available\ |
| 02:07:19 | FromDiscord | <Elegantbeef> I'm talking about generally |
| 02:08:59 | FromDiscord | <kalbhairab> Ohh |
| 02:10:25 | FromDiscord | <Elegantbeef> Atleast it's my view that a nim with no imports should pretty much just have the builtins and basic operations for them |
| 02:10:45 | FromDiscord | <kalbhairab> Ohh |
| 02:11:41 | FromDiscord | <Elegantbeef> I do say it does pollute the namespace rika, say you dont like nim's `fmt` for whatever reason so implement your own, you now get told "ambigious call for `fmt`" when you try to invoke your own |

| 02:16:03 | FromDiscord | <Elegantbeef> Presently this is still nim related |

| 06:41:44 | FromDiscord | <sOkam!> like, if cimterop was inspired by nimline... but they are different projects... why are they different and why would one decide on one over the other?↵that type of question is what I don't know how to answer, so don't know how/what to choose |
| 06:42:28 | FromDiscord | <demotomohiro> If you use only a few functions/types in large C code, write binding manually that only import what you use. |
| 06:45:48 | FromDiscord | <Elegantbeef> I think nimterop and futhark require the user have libclang on their pc or similar |
| 06:55:37 | FromDiscord | <geekrelief> In reply to @Elegantbeef "I think nimterop and": Nimterop only requires gcc. Futhark needs libclang |
| 06:56:17 | FromDiscord | <Elegantbeef> Ah my bad |
| 07:04:33 | FromDiscord | <geekrelief> In reply to @sOkam! "I'm having a really": If the API is small, just bind it manually as demotomohiro suggests. Quite a few people have used Futhark with success, but the libclang requirement might be annoying on Windows. I forked nimterop and use it for The Machinery. It works well enough for me, but probably has a steeper learning curve than Futhark. |
| 07:05:57 | FromDiscord | <sOkam!> In reply to @geekrelief "If the API is": it is no small project, and it has no api. the games are hooked straight into the engine. its not like the current theme of lib-ified engines with clean and nice apis |
| 07:06:43 | FromDiscord | <Elegantbeef> Someone clearly talking about the quake engine |
| 07:07:18 | FromDiscord | <sOkam!> yep |
| 07:07:41 | FromDiscord | <Elegantbeef> Well then the best thing to do is wrap what you need as you need it |
| 07:08:03 | FromDiscord | <Elegantbeef> So use c2nim + hand wrapped stuff |
| 07:08:28 | FromDiscord | <sOkam!> i see |
| 07:08:31 | FromDiscord | <Elegantbeef> I think things like nimterop/futhark would be more annoying for something like this, i could be wrong though |
| 07:08:58 | FromDiscord | <sOkam!> should I use nimline/cinterop as the projects suggest, just to get the code up and compiling? |
| 07:09:11 | FromDiscord | <sOkam!> or just straight to c2nim+manual? |
| 07:12:03 | FromDiscord | <Elegantbeef> I dont know what to say there's a lot of code spread out, so wrapping it all automated or manually is going to be a hassle, I guess futhark/nimterop might be able to give you the C api directly in Nim, no clue really |
| 07:12:13 | FromDiscord | <Elegantbeef> I havent used them ever so no clue how effective they are for large apis like this |
| 07:12:46 | FromDiscord | <sOkam!> kk |
| 07:15:13 | FromDiscord | <sOkam!> also, dunno if we were talking about the same thing↵you guys say nimterop, but i was thinking of Cinterop↵dunno how much difference there is between them |
| 07:15:37 | FromDiscord | <sOkam!> nimterop is more akin to futhark? or are cinterop and nimterop the same type of tool? |
| 07:15:45 | FromDiscord | <Elegantbeef> I never have heard of cinterop before |
| 07:15:54 | FromDiscord | <sOkam!> https://github.com/n0bra1n3r/cinterop |
| 07:16:39 | FromDiscord | <sOkam!> this paragraph was the source of my questions, basically https://media.discordapp.net/attachments/371759389889003532/948478930548064266/unknown.png |
| 07:17:45 | FromDiscord | <sOkam!> the other one of my doubts was this: https://github.com/sinkingsugar/nimline |
| 07:18:35 | FromDiscord | <sOkam!> but you guys were sending me to wrappers/bindings, so not sure if these tools could change the answer |
| 07:19:31 | FromDiscord | <Elegantbeef> Well you're going to need to wrap the API, nimline does it in a sort of dynamic way where it just assumes code is valid, the other method is to emit the Nimcode from the C code like Futhark/Nimterop/C2nim do |
| 07:20:44 | FromDiscord | <Elegantbeef> The latter is better if you actually plan on using the code, as it's concrete |
| 07:21:59 | FromDiscord | <sOkam!> is there any specific benefit to c2nim vs futhark/nimterop? |
| 07:23:59 | FromDiscord | <Elegantbeef> The generated code is what people use, instead of the methods of generating the code, so it's a bit more concrete |
| 07:24:50 | * | PMunch joined #nim |
| 07:25:09 | FromDiscord | <sOkam!> not sure i follow, sry me dummie 😔 ↵what do you mean by "concrete"? |
| 07:26:20 | FromDiscord | <Elegantbeef> With C2Nim your share your nim files that are actual `importc`'d types/procs, with futhark/nimterop you share files that run over the C code and emit the bindings and your share the wrapping templates/procedures |
| 07:30:09 | FromDiscord | <sOkam!> do you have an example of a project made with c2nim, and one with either of the others?↵maybe ill understand what you mean by seeing the code compared |
| 07:30:37 | FromDiscord | <sOkam!> i get the feeling that i understand it the idea in such a superficial level, that i wont be able to actually use any of them 😔 |
| 07:30:58 | FromDiscord | <sOkam!> (edit) removed "any of" |
| 07:31:27 | FromDiscord | <Elegantbeef> Compare https://gitlab.com/define-private-public/stb_image-Nim to the futhark example |

| 07:33:26 | FromDiscord | <Elegantbeef> There are benefits with futhark in that it regenerates, so library changes that are breaking will be caught |
| 07:34:11 | PMunch | That's pretty much why I wrote Futhark. Well that and having something which actually just works without hours/days of hair pulling frustration |

| 07:35:31 | PMunch | @Elegantbeef, haha, maybe when I add the next version with better folder support :) |

| 07:36:57 | FromDiscord | <Elegantbeef> There is a `--checkAbi` flag apparently |

| 07:41:42 | FromDiscord | <sOkam!> In reply to @PMunch "That's pretty much why": do you think futhark might have issues with something when dealing with q3 engine? |
| 07:42:06 | PMunch | Hard to tell without having ever looked at the sources for q3 engine |
| 07:42:15 | PMunch | But if it's pretty standard C code then you should be fine |
| 07:42:23 | FromDiscord | <sOkam!> what does futhark currently have issues with? |
| 07:42:38 | PMunch | Mostly macros that the user is supposed to use |
| 07:42:48 | PMunch | It handles macros used by the library just fine |
| 07:43:08 | FromDiscord | <sOkam!> its ansi C '89, coded in 1999 by tons of carmack-ian weirdness. dunno how standard or non-standard that will be 🤔 |
| 07:43:17 | PMunch | But if they define macros that the user is supposed to use it starts to struggle because those aren't really typed |
| 07:43:20 | PMunch | Do you have a link? |
| 07:43:24 | FromDiscord | <sOkam!> ye |
| 07:43:52 | FromDiscord | <sOkam!> This is the one that we use nowadays for mods↵https://github.com/ec-/Quake3e |
| 07:45:23 | PMunch | From the two files I've opened it seems like it should be fine |
| 07:45:32 | FromDiscord | <sOkam!> that project has no gamecode. you can see the gamecode specific things in this other engine inside cgame/game/q3_ui : https://github.com/ioquake/ioq3 |
| 07:46:02 | FromDiscord | <sOkam!> In reply to @PMunch "From the two files": kk. any tuts written for futhark? i literally haven't used it yet because i have no clue where to start |
| 07:46:32 | PMunch | Not apart from the sample code and the various wrappers I've helped people write in the issues |
| 07:46:45 | FromDiscord | <sOkam!> 👌 |
| 07:47:11 | PMunch | But it's pretty simple, you just give it a block of things to import from C, and then you sit back and enjoy your wrapper |
| 07:47:44 | FromDiscord | <sOkam!> yeah, someone recommended me that before |
| 07:47:58 | PMunch | Might've been me :P |
| 07:48:11 | FromDiscord | <sOkam!> I don't know how to go about that, though. like, i know its probably dummie not being able to understand that, but i cant grasp how |
| 07:48:42 | FromDiscord | <sOkam!> i have a list of .h files that i generated, but what do i do with that? |
| 07:48:58 | PMunch | That you generated? |
| 07:49:05 | FromDiscord | <sOkam!> yeah with find or ls |
| 07:49:09 | FromDiscord | <sOkam!> or similar, dont remember |
| 07:49:14 | PMunch | Uhm, don't do that |
| 07:49:20 | FromDiscord | <sOkam!> see? |
| 07:49:21 | FromDiscord | <sOkam!> 😄 |
| 07:50:30 | PMunch | Download the Quake library from GitHub, then have an `importc` block which tells futhark where to find clang standard libraries and the libraries you just cloned (the two first lines of the stb example) then just list all the .h files you want to import the same way you would do it in C |
| 07:51:58 | FromDiscord | <sOkam!> this is what that aforementioned list looks like https://media.discordapp.net/attachments/371759389889003532/948487816957009920/unknown.png |
| 07:54:54 | PMunch | Why have you only copied those things out? |
| 07:55:03 | PMunch | They must depend on some other files as well? |
| 07:55:29 | FromDiscord | <sOkam!> because, like i said, i have no clue how to get the .h file list |
| 07:55:37 | FromDiscord | <sOkam!> other than by bash scripting |
| 07:56:05 | PMunch | You don't need a list though? |
| 07:56:58 | FromDiscord | <sOkam!> sent a code paste, see https://play.nim-lang.org/#ix=3R8Z |
| 07:57:21 | FromDiscord | <Elegantbeef> You treat `importc` like the `#include` in C |
| 07:57:27 | FromDiscord | <Elegantbeef> So you importC the header files you want |
| 07:57:38 | PMunch | Exactly |
| 07:57:54 | FromDiscord | <Elegantbeef> So you might want to importC all the files of a folder together so you can expose them as a Nim module |

| 07:59:39 | PMunch | Doesn't have to do anything, like the "hello world" of using it |
| 08:00:13 | FromDiscord | <sOkam!> the engine is so hairy, that we all start by modding the original game directly. i dont think such a minimal example exists |
| 08:00:41 | FromDiscord | <sOkam!> only a handful of people actually understand the architecture enough to dissect it in such a way |
| 08:01:21 | PMunch | Then it's not really a library is it? |
| 08:01:41 | FromDiscord | <sOkam!> which is my point, its an engine not really an api or library |
| 08:01:50 | FromDiscord | <Elegantbeef> It's not a library it's C code so it's going to be 'fun' to make Nim work with it |
| 08:01:53 | FromDiscord | <sOkam!> so don't know how to approach the issue |
| 08:03:25 | FromDiscord | <sOkam!> its like, if you have firefox already coded, and you want to start using firefox code from nim (or any fully fledged app that's not lib-ified) |

| 08:04:44 | nrds | <Prestige99> Anyone here using windows? My friend installed nim from the site and ran the "finish.exe" to add nim to his path but it seems to not have worked |
| 08:04:51 | nrds | <Prestige99> Curious if anyone else is having this issue |
| 08:04:58 | FromDiscord | <Elegantbeef> Well you get to generate C code using Nim then include it in your C file and call it |
| 08:05:01 | FromDiscord | <Elegantbeef> Did anti virus get involved prestige? |
| 08:05:05 | FromDiscord | <Elegantbeef> Did they restart? |
| 08:05:06 | FromDiscord | <sOkam!> from what I know about the engine, the "only wrap those things you need" actually means "wrap and rewrite the whole main loop in a new nim main loop function", and start from there |
| 08:05:18 | FromDiscord | <Elegantbeef> Windows path is a funky beast |
| 08:05:29 | nrds | <Prestige99> Yeah antivirus complained but he told it to continue |
| 08:05:32 | nrds | <Prestige99> the install, I mean |
| 08:05:32 | FromDiscord | <Elegantbeef> Well that'd be one way of doing it |
| 08:08:02 | FromDiscord | <sOkam!> In reply to @Elegantbeef "Well you get to": that's another approach I thought about, but that wouldn't really be a nim engine eventually.↵it would still be C that uses code auto-generated from nim compiling as C code instead of as binary |
| 08:08:24 | FromDiscord | <Elegantbeef> It's never going to be a "Nim engine" |
| 08:08:45 | FromDiscord | <Elegantbeef> It's 23 years of C, if you want a Nim engine, write it in Nim 😛 |
| 08:09:07 | FromDiscord | <sOkam!> i would, but it wouldn't be the same |
| 08:10:06 | FromDiscord | <sOkam!> for some freaky weird reason i dont understand, not even id2 / id4 feel good enough 😦↵i tried all engines, and nothing is close. definitely not the modern ones with gjk/bvh |
| 08:10:32 | FromDiscord | <sOkam!> (edit) "feel" => "feels" | "feelsgood enough ... 😦↵i" added "compared to id3" |
| 08:10:48 | FromDiscord | <Elegantbeef> Well make an engine that feels the same, it'll probably be less of a pain than trying to make this work nicelyt |
| 08:11:46 | FromDiscord | <sOkam!> aware of how many people have said that? 25y, tens of games, hundreds of programmers, none achieved what it was achieved with id3. not even the same guys with their very next engine (id4) |
| 08:12:01 | FromDiscord | <sOkam!> i know its not an easy task |
| 08:12:14 | FromDiscord | <sOkam!> just trying to understand how, that's all. even if its hard |

| 08:25:34 | FromDiscord | <Elegantbeef> With what pmunch said you just include `one.h` and `two.h` |

| 08:25:45 | FromDiscord | <Elegantbeef> Now if he's a liar that's bad |
| 08:26:16 | FromDiscord | <sOkam!> Ok, so then I would only need to manage the main loop and the functions that it calls |
| 08:26:33 | * | jjido joined #nim |
| 08:28:35 | FromDiscord | <sOkam!> basically, this function https://github.com/ec-/Quake3e/blob/65db7c877cb37e37315b6bfbf52c1f3066376436/code/win32/win_main.c#L740 |
| 08:30:01 | FromDiscord | <sOkam!> how does futhark do its thing in the background?↵does it manage the C compiler automatically or smth? |
| 08:38:22 | nrds | <Prestige99> Elegantbeef do you know how to link dlls on windows by chance? |
| 08:38:49 | nrds | <Prestige99> Trying to get my sdl project to compile on windows but have been running into issues, I think it's not finding the files |
| 08:38:58 | FromDiscord | <Elegantbeef> The same as on linux |
| 08:42:08 | nrds | <Prestige99> Okay how do you do that? :P |
| 08:42:20 | PMunch | Sorry I was in a meeting |
| 08:42:33 | FromDiscord | <Elegantbeef> Download the dev files then import the file with dynlib |
| 08:42:48 | FromDiscord | <Elegantbeef> If static linking also having the static library and linking it with command line arguments |
| 08:43:59 | PMunch | sOkam, so basically what Futhark does is that it loads the header files you specified with libclang, then it asks Clang to list out everything which is defined in those headers. It then converts those definitions to Nim, and tells it to grab it from the C sources. So in Nim you just import the C header files, Futhark converts them to Nim definitions, and when you call them in Nim it will call the C functions for you. |
| 08:44:21 | FromDiscord | <Elegantbeef> Does it recurse down includes? |
| 08:45:30 | PMunch | Yes |
| 08:45:53 | FromDiscord | <demotomohiro> If you use dll with https://docs.microsoft.com/en-us/troubleshoot/windows-client/deployment/dynamic-link-library#types-of-dlls |
| 08:45:57 | PMunch | Well it recurses down the includes to get the definitions it needs, but it only exports the definitions for the files you've specified |
| 08:46:38 | PMunch | This is what I was talking about with the folder import thing. I want to add a flag which makes it so that it will add all the definitions in a given folder automatically |
| 08:47:02 | PMunch | So For this you could say that you wanted `one.h` and everything it imports which lives in `Quake32/code` |
| 08:47:20 | FromDiscord | <demotomohiro> If you use dll with Load-time dynamic linking, you need to add .lib file to linker. That is bit different from Linux. If you use dll as Run-time dynamic linking, you don't need to link .lib or .dll files at link time. |
| 08:47:48 | PMunch | The reason I've done it like this is because otherwise it will go all the way to the top of the C definitions and start pulling in the C definition for an integer and things like that |
| 08:48:25 | PMunch | So with the above sample you pasted sOkam it would look something like this in Nim: https://play.nim-lang.org/#ix=3R9h |
| 08:48:53 | PMunch | And in myMethod you could call procedures from one.h and two.h and access their types just as if it was written in C |
| 08:52:29 | nrds | <Prestige99> Elegantbeef any guides on that? |
| 08:52:38 | nrds | <Prestige99> I don't know how any of this linking business works |
| 08:52:57 | FromDiscord | <abdu> How is Nim for C's #define preprocessor eg.↵#define foo 99 |
| 08:53:34 | PMunch | @abdu, not sure what you mean |
| 08:53:37 | FromDiscord | <demotomohiro> `const Foo = 99` |
| 08:53:51 | PMunch | In Nim you would do it like @demotomohiro said, with a compile-time constant |
| 08:56:00 | FromDiscord | <demotomohiro> If you want macro like `#define min(x, y) ((x) < (y) ? (x): (y))`, `template min(x, y: untyped): untyped = if x < y: x else: y`. |
| 08:56:03 | PMunch | You could use `{.emit: ["#define ", somename, " ", something].}` or maybe even `let foo {.codegenDecl: "#define $2 $1".} = 99` to put such defines into Nim code |
| 08:56:34 | PMunch | Prestige, do you just need to link a DLL into your program? |
| 08:58:00 | nrds | <Prestige99> Uh well now we're trying to do static linking |
| 08:58:07 | nrds | <Prestige99> have the .lib files |
| 08:58:28 | FromDiscord | <demotomohiro> On windows, .dll is not a file linked to executable file. Link .lib file with --passL:"foo.lib". |
| 08:58:49 | nrds | <Prestige99> do we need dynlibOverride for that? |
| 09:00:23 | PMunch | Nah I think that is just to stop procedures marked with `{.dynlib.}` from being imported from a dynamic library |
| 09:00:52 | PMunch | Like if you wanted to use the standard library ssl implementation but static link it |
| 09:01:06 | nrds | <Prestige99> hmm okay |
| 09:01:50 | FromDiscord | <sOkam!> PMunch, you mentioned something about macros earlier. Q3 engine has quite a lot of them↵what happens in futhark with macros? does it handle them properly? |
| 09:03:13 | PMunch | It depends |
| 09:03:29 | PMunch | It handles all the macros that just live inside the library just fine |
| 09:04:05 | PMunch | And it should handle most static values just fine |
| 09:04:29 | PMunch | But macros which are intended to be called like a procedure is a bit worse |
| 09:04:58 | FromDiscord | <sOkam!> In reply to @PMunch "But macros which are": there\ are procedures, yep |
| 09:05:07 | FromDiscord | <sOkam!> (edit) "there\" => "there" | "yep" => "yep. quite a few" |
| 09:05:09 | PMunch | Which you are supposed to call? |
| 09:05:56 | FromDiscord | <sOkam!> hmmm, don't have an answer to that yet. maybe the C code does, but you'd call them if you write in the engine in C, yep |
| 09:06:22 | FromDiscord | <sOkam!> unless they are behind some other functions and can be avoided, which I don't know yet |
| 09:06:30 | FromDiscord | <sOkam!> are they fine if they are called from C code only? |
| 09:07:38 | FromDiscord | <abdu> In reply to @demotomohiro "If you want macro": solved! thanks |
| 09:08:39 | PMunch | sOkam, yeah they're fine as long as they are behind C code |
| 09:09:10 | PMunch | The problem is that clang can't figure out the signature of such a macro, because it doesn't really have one, so I can't convert it into anything useful in Nim |
| 09:16:13 | nrds | <Prestige99> So I'm having an issue getting this lib statically linked, "undefined reference to GPU_TRANSLATE" and any other functions that are used. Here https://github.com/Vladar4/sdl2_nim/blob/master/sdl2_nim/sdl_gpu.nim#L1703 |
| 09:16:32 | nrds | <Prestige99> It's using the dynlib pragma, don't know what I'm missing here |
| 09:16:55 | nrds | <Prestige99> using --passL:path/to/my.lib |
| 09:18:02 | PMunch | Shouldn't that be `--passL:"-Lpath/to/library -lmy"`? |
| 09:18:22 | PMunch | --passL only sends things to the linker |
| 09:18:22 | nrds | <Prestige99> I have no idea |
| 09:18:49 | PMunch | On Linux at least -L is used to pass a folder to search for libraries |
| 09:19:07 | PMunch | And -l to link to an actual library (but I think dynlib should handle that automatically) |
| 09:19:08 | FromDiscord | <demotomohiro> `GPU_TRANSLATE` is a symbol in your static lib? Or it is in other library? |
| 09:19:34 | nrds | <Prestige99> It should be in the static lib afaik |
| 09:19:44 | PMunch | So you would need `--passL:"-Lpath/to/lib"` in order to pass the folder that Nim will go looking for that library |
| 09:20:00 | PMunch | But since it uses dynlib you probably need to use dynlibOverride |
| 09:20:45 | nrds | <Prestige99> I thought that's what clibdir was for |
| 09:21:41 | * | Gustavo6046 quit (Quit: Leaving) |
| 09:21:43 | nrds | <Prestige99> I got it to build using absolute paths, but the binary does nothing. Weird |
| 09:21:51 | PMunch | Oh, never seen that before, but yeah I guess that does the same thing |
| 09:23:20 | FromDiscord | <demotomohiro> Do you got error like `path/to/my.lib was not found`? |
| 09:23:53 | nrds | <Prestige99> Can't get either of those to work for some reason - the error is "undefined reference to GPU_TRANSLATE" etc |
| 09:26:06 | * | xaltsc quit (Read error: Connection reset by peer) |
| 09:33:14 | nrds | <Prestige99> after statically linking using absolute paths, I had to put the dll's next to the executable for it to run |
| 09:33:19 | nrds | <Prestige99> so the static libs aren't actually static? |
| 09:33:39 | PMunch | No that just sounds like you dynamically linked them |
| 09:34:26 | nrds | <Prestige99> I'm using dynlibOverrideAll so I don't think so..? |
| 09:34:37 | nrds | <Prestige99> Unless that doesn't do what I think it does |
| 09:35:15 | PMunch | Well it's not very static if you need the files to be there is it? |
| 09:35:33 | nrds | <Prestige99> Yeah that's my point |
| 09:36:01 | nrds | <Prestige99> maybe the .lib file is just a loader for the dll |
| 09:36:28 | nrds | <Prestige99> SDL2.lib is only 171kb but the .dll is 2179kb, seems weird |
| 09:37:24 | FromDiscord | <demotomohiro> File size depends on compiler options. |
| 09:38:00 | FromDiscord | <demotomohiro> Maybe your .lib was not built correctly? |
| 09:38:14 | nrds | <Prestige99> I got it from the sdl website so, hopefully it's correct |
| 09:38:58 | PMunch | Why do you want to static link it anyways? |
| 09:39:20 | nrds | <Prestige99> Easier to ship binaries |
| 09:40:06 | FromDiscord | <demotomohiro> Did you read SDL2 manual? It should tells which library you need to link. Maybe you need to link other library. |
| 09:42:18 | FromDiscord | <demotomohiro> Maybe, C compiler that built .lib file and C compiler your Nim uses are different and .lib file is not compatible with your C compiler |
| 09:42:55 | nrds | <Prestige99> idk about that |
| 09:48:54 | nrds | <Prestige99> Well I've been working on this for too long, will try getting it working again another day |

| 10:09:23 | FromDiscord | <MaskDuck> nim looks cooler than python ig |

| 10:09:42 | FromDiscord | <MaskDuck> (edit) "i right now only code using python ... " added "(proficient)" |
| 10:10:24 | FromDiscord | <MaskDuck> maybe ill learn nim |
| 10:10:43 | FromDiscord | <MaskDuck> btw i think nim structure looks like a command line™️ |
| 10:11:34 | PMunch | Like a command line? |
| 10:11:51 | FromDiscord | <Rika> Good to hear that you like it |
| 10:12:07 | PMunch | Prestige, just take into account that you probably need to GPL license whatever it is you're doing if you want to static link against SDL2 |
| 10:12:29 | nrds | <Prestige99> Yeah that's fine |
| 10:12:40 | FromDiscord | <Rika> Is SDL2 GPL and not lesser? |
| 10:12:57 | FromDiscord | <MaskDuck> yup |
| 10:13:08 | PMunch | Ah it might be LGPL, I just found some references to it when I searched for static linking things earlier |
| 10:13:18 | PMunch | And it's not that hard to ship a couple extra dlls |
| 10:13:38 | FromDiscord | <Rika> It’s zlib license |
| 10:13:50 | PMunch | How does that work, if you write a program which has staticRead the DLLs during compile-time and if the libraries don't exists it spits them out before loading them? |
| 10:14:35 | FromDiscord | <Rika> Semi-static hahaha |
| 10:15:00 | FromDiscord | <Rika> I can imagine AV would hate that though |
| 10:15:09 | FromDiscord | <demotomohiro> Nim has command invocation syntax and many proc/func/template/macro can be called like command line. |
| 10:15:13 | FromDiscord | <demotomohiro> https://nim-lang.org/docs/manual.html#procedures-command-invocation-syntax |
| 10:15:19 | FromDiscord | <MaskDuck> ho |
| 10:15:21 | FromDiscord | <MaskDuck> how can i |
| 10:15:24 | FromDiscord | <MaskDuck> install nim |
| 10:15:29 | FromDiscord | <MaskDuck> using source distributor |
| 10:15:36 | FromDiscord | <MaskDuck> i can find the build.sh file |
| 10:16:04 | FromDiscord | <MaskDuck> cant |
| 10:17:12 | FromDiscord | <demotomohiro> Here is how to build from source: https://github.com/nim-lang/nim#compiling |
| 10:19:02 | FromDiscord | <demotomohiro> There are build_all.sh for Linux/Mac and build_all.bat for Windows. |
| 10:21:11 | PMunch | Source distributor? |
| 10:21:18 | PMunch | I recommend you do it through choosenim |
| 10:21:36 | PMunch | That way you're sure it's installed correctly, and that you can easily upgrade to future versions |
| 10:23:06 | FromDiscord | <MaskDuck> aic thanks |
| 10:23:15 | FromDiscord | <MaskDuck> In reply to @PMunch "I recommend you do": i tried choosenim |
| 10:23:23 | FromDiscord | <MaskDuck> but it is too slow |
| 10:24:07 | PMunch | Too slow? |
| 10:24:14 | FromDiscord | <MaskDuck> do we neeed any dependacies |
| 10:24:28 | PMunch | It literally just downloads a tarball and extracts it |
| 10:24:33 | PMunch | How can that be too slow? |
| 10:24:49 | FromDiscord | <MaskDuck> it is faster now |
| 10:24:50 | PMunch | As for dependencies you need a C compiler, but not much else |
| 10:24:55 | FromDiscord | <MaskDuck> ok i installed thanks guys |
| 10:25:04 | FromDiscord | <MaskDuck> now |
| 10:25:09 | FromDiscord | <MaskDuck> if i wanna write hello world |
| 10:25:15 | FromDiscord | <MaskDuck> `echo "Hello World"`? |
| 10:26:11 | PMunch | Yup |
| 10:26:13 | FromDiscord | <demotomohiro> yes. Then save it to file hello.nim and `nim c -r hello.nim` |
| 10:26:41 | FromDiscord | <MaskDuck> ah thanks ya |
| 10:27:05 | FromDiscord | <MaskDuck (MaskDuck)> tysm |
| 10:27:19 | PMunch | I mean technically you don't even need to save it to a file: nim --eval:'echo "hello world"' |
| 10:27:28 | FromDiscord | <MaskDuck> lmao |

| 10:28:06 | PMunch | Well you didn't install it properly then |
| 10:28:15 | PMunch | You need to make sure that the Nim binary is in your path |
| 10:28:28 | PMunch | Ad do you have `nim` repeated twice, or is that just your shell? |
| 10:29:11 | PMunch | I think choosenim asks you if you want it to add it to your path for you |
| 10:30:00 | FromDiscord | <MaskDuck> In reply to @PMunch "I think choosenim asks": well |
| 10:30:05 | FromDiscord | <MaskDuck> it doesnt add it into the path |
| 10:30:16 | FromDiscord | <MaskDuck> and the nim folder is something contain the `hello.nim` file |
| 10:30:57 | FromDiscord | <MaskDuck> In reply to @PMunch "I think choosenim asks": well it doesnt |
| 10:31:57 | FromDiscord | <Rika> In reply to @MaskDuck "well it doesnt": It does, otherwise it’s somehow broken |
| 10:32:15 | FromDiscord | <Rika> In reply to @MaskDuck "it doesnt add it": It can’t add it for you, you have to do that yourself in this case |
| 10:33:24 | PMunch | You shouldn't put your project files in the Nim compiler folder |
| 10:33:30 | PMunch | I mean you can, but you shouldn't |
| 10:34:16 | PMunch | Either way it's just a matter of getting your shell to find the Nim binary. If you have built the Nim binary from sources it should be enough to add the `bin` folder in the Nim sources you've got to your path |
| 10:34:30 | PMunch | Simply update your PATH variable to include that folder |
| 10:34:49 | * | jjido quit (Quit: My MacBook Air has gone to sleep. ZZZzzz…) |
| 10:34:54 | PMunch | Of course if you don't want to do that you could pass the full path to the compiler when you want to invoke it |
| 10:35:31 | FromDiscord | <Rika> Or symlink into a bin folder you already have in your path lol |
| 10:36:10 | PMunch | That would probably cause Nim to fail to find the standard library though wouldn't it? |
| 10:37:19 | FromDiscord | <Rika> Dunno never used it |
| 10:37:37 | FromDiscord | <Rika> If so then that should be fixed |
| 10:38:09 | PMunch | Oh well, time for lunch |
| 10:38:10 | * | PMunch quit (Quit: leaving) |
| 10:42:58 | FromDiscord | <demotomohiro> Running nim with absolute path worked. |

| 10:52:34 | nrds | <Prestige99> Is there a way to have a template return a bool, but also allow the user to pass in a body? |
| 10:52:56 | FromDiscord | <Rika> Templates don’t really “return” |
| 10:53:42 | nrds | <Prestige99> yeah |
| 10:53:50 | nrds | <Prestige99> But do you know what I mean? |
| 10:53:53 | FromDiscord | <Rika> Make a template with a block inside, put the passes body in the block, then after the body at the end of a block do an “explicit value return” |
| 10:54:00 | FromDiscord | <demotomohiro> `template foo(body: untyped): bool = body; true`? |
| 10:54:16 | nrds | <Prestige99> yeah |
| 10:54:17 | FromDiscord | <Rika> ^Pretty much the same as what I mean except with a block too |
| 10:55:09 | FromDiscord | <demotomohiro> sent a code paste, see https://play.nim-lang.org/#ix=3R9H |

As far as I can tell, std/unicode only has support for runes. Related question: why does std/unicode deviate from the unicode terminology (rune = code point, character = grapheme cluster)? |
| 12:05:19 | FromDiscord | <Michal Maršálek> (edit) "yeah" => "each" |

| 12:07:03 | PMunch | And to print out each unicode character you would probably do `for c in myStr.runes: echo c` |
| 12:07:12 | FromDiscord | <Michal Maršálek> In reply to @PMunch "rune is a fairly": I neber heard it but I see that golang uses that word too. |
| 12:07:24 | PMunch | It's a nice short word :) |
| 12:07:56 | PMunch | @Rika, I guess things like zero-width joiners are their own code points but not a printable character |
| 12:08:02 | FromDiscord | <Michal Maršálek> In reply to @Rika "What is the difference": What users usually perceive as one character can be one or multiple codepoints. |
| 12:08:09 | PMunch | Exactly |

| 12:49:12 | FromDiscord | <Rika> isnt bigint specifically mentioning that its not optimised |
| 12:49:19 | PMunch | Yup |
| 12:50:18 | PMunch | bigint specifically says that it is not fast. Nim is faster than Python, but some Python libraries are written in highly optimised C code and just shimmied in which I guess is what's going on here. If you use a library which is actually optimised for speed you will get more speed (who'da thunk?) |
| 12:51:24 | FromDiscord | <Rika> lol |
| 12:51:56 | PMunch | But yeah, if you don't write Python code which essentially boils down to calling out to a C library that does all the work Nim will be faster |
| 12:52:28 | PMunch | If you find a similarly optimised Nim library Nim is likely to be faster again because of faster startups |
| 12:54:00 | PMunch | Hmm, I'm porting some C code to Nim, it adds a signal handler for SIGINT which just sets an atomic int and then the main loop is looking for that atomic int and stops if it is 0. Then it has cleanup after the loop |
| 12:54:19 | PMunch | What would be the best way to implement something similar in Nim that can be Ctrl+C'ed with proper shutdown code? |

| 20:44:05 | FromDiscord | <sOkam!> nvm i think this answered it https://media.discordapp.net/attachments/371759389889003532/948682127438913566/unknown.png |

| 21:22:00 | nrds | <Prestige99> Is there a way to do something like this? https://play.nim-lang.org/#ix=3RcS |
| 21:22:10 | nrds | <Prestige99> Maybe need to write some sort of macro |
| 21:22:36 | FromDiscord | <b4mbus> How do I achieve something similiar to this C++ code but in Nim? Someone pointed me to `method`s but Im incredibely confused how they work and how I should use them |
| 21:22:48 | FromDiscord | <b4mbus> sent a code paste, see https://play.nim-lang.org/#ix=3RcT |

| 21:33:20 | FromDiscord | <exelotl> In reply to @b4mbus "How do I achieve": Like this: https://play.nim-lang.org/#ix=3RcW |
| 21:34:00 | FromDiscord | <b4mbus> oh, so Nim doesnt have a concept of a pure virtual function/pure method |
| 21:34:15 | FromDiscord | <b4mbus> thanks a lot |
| 21:35:59 | FromDiscord | <exelotl> yeah I think it doesn't |
| 21:39:15 | FromDiscord | <Rika> Not without external libraries |

| 22:33:17 | FromDiscord | <kbsec> What exactly does `{.pure.}` pragma do? I have a small demo here https://play.nim-lang.org/#ix=3Rd1 where I would expect the runtime identifier for the attribute in the object defined with `{.pure.}` for each field to be ommited, but it would seem the object is the same w/ or w/out the pragma ? |
| 22:35:25 | FromDiscord | <zidsal> Quick question, I have a seq of a variant type e.g JsonNode and I know for a fact they are all JInt. Is there a way I can tell the compiler I know what the kind is without manually checking the enum value? |
| 22:43:12 | * | cornfeedhobo joined #nim |
| 22:48:28 | FromDiscord | <Elegantbeef> It removes runtime type information on objects that are inheritable↵(@kbsec) |
| 22:49:08 | FromDiscord | <Elegantbeef> https://nim-lang.org/docs/manual.html#types-cast-uncheckedassign i think this works↵(@zidsal) |

| 22:53:00 | FromDiscord | <Elegantbeef> that offsets the ptr of `x` by w so in nim i'd be `int (cstrLen(x[w].addr))` |
| 22:53:28 | FromDiscord | <Elegantbeef> or you could just do `cstrlen(x) - w` |
| 22:53:46 | FromDiscord | <Elegantbeef> Actually i'm wrong arent i |
| 22:53:49 | FromDiscord | <demotomohiro> In reply to @kbsec "What exactly does `{.pure.}`": https://play.nim-lang.org/#ix=3Rd6 |
| 22:54:09 | FromDiscord | <Elegantbeef> it's offsetting the char\ by `w` so it'd be `cast[ptr UncheckedArray[cstring]](x)[w]` |
| 22:58:00 | FromDiscord | <Elegantbeef> that's still not right God C can be awful |
| 22:58:05 | FromDiscord | <demotomohiro> I think `strSize = x.len - w`. |
| 22:58:13 | FromDiscord | <ATwenty0ne> lol yea this one is a head scratcher |
| 22:58:23 | FromDiscord | <Elegantbeef> No `w` is a pointer |
| 22:58:27 | FromDiscord | <Elegantbeef> I mean x is a pointer |
| 22:58:30 | FromDiscord | <Elegantbeef> `x + w` offsets the pointer by w bytes |
| 22:59:27 | FromDiscord | <Elegantbeef> so the best thing to do i guess is manual arithmetic `cstrlen(cast[cstring](cast[int](x) + w)))` |
| 22:59:54 | FromDiscord | <zidsal> Thanks @ElegantBeef |
| 23:00:23 | FromDiscord | <Elegantbeef> That should work twentyone, sorry for the 30 wrong answers 😛 |
| 23:00:39 | FromDiscord | <ATwenty0ne> lol its ok, I appreciate you helping, thanks! |
| 23:01:37 | FromDiscord | <Elegantbeef> I fully blame C's inanity |
| 23:01:57 | FromDiscord | <Elegantbeef> Also are you interoping with C or writing pure Nim? |
| 23:04:25 | FromDiscord | <ATwenty0ne> interoping |

| 23:35:35 | girvo | Hi all :) |
| 23:36:20 | FromDiscord | <Elegantbeef> Hello |
| 23:36:40 | girvo | Anyone have a good example for Nim-ified wrappers of C libraries that take callbacks? I'm having issues passing procs to a {.cdecl.} wrapper, as trying to call a proc declared outside of it is an illegal capture |
| 23:36:47 | girvo | Theres gotta be a better way I'm missing |
| 23:36:55 | FromDiscord | <Elegantbeef> Cdecls cannot have captures |
| 23:37:12 | FromDiscord | <Elegantbeef> Closures are incompatible with cdecl due to the environment carried with them |
| 23:37:18 | girvo | Yeah figured as much |
| 23:37:36 | FromDiscord | <Elegantbeef> What's your callback and what's your code trying to do? |
| 23:37:45 | girvo | One tick I'll grab the definitions in a pastebin for ya |
| 23:39:45 | girvo | https://pastebin.com/j9trbgGQ |
| 23:40:20 | girvo | `var t = newTask(sendAT, "sendAT", (16384 * 3).SzBytes)` is what I wanted to achieve lol where sendAt is just a regular void proc |
| 23:40:47 | FromDiscord | <Elegantbeef> Can you store `cb` on the object that's passed to the procedure? |
| 23:40:58 | girvo | I can actually |
| 23:41:05 | girvo | Oh! |
| 23:41:08 | girvo | I see :D |
| 23:41:08 | FromDiscord | <Elegantbeef> so like could you do `cast[MyObject](a1).cb()` |
| 23:41:10 | * | jmdaemon joined #nim |
| 23:41:15 | FromDiscord | <Elegantbeef> well `ptr MyObject` |
| 23:41:16 | girvo | Yeah I should be able to. I'll give it a shot |
| 23:41:35 | FromDiscord | <Elegantbeef> Your `pointer` is your closure environment somewhat |
| 23:42:15 | girvo | Yep that's exactly how FreeRTOS uses it |
| 23:43:25 | girvo | Hah she compiles at least |
| 23:43:35 | girvo | Lets see if it runs or blows my tiny stack. Embedded is fun |
| 23:43:45 | FromDiscord | <System64 ~ Flandre Scarlet> https://nimble.directory/pkg/dimscord↵Does it support the latest Discord API features? |
| 23:46:21 | FromDiscord | <Elegantbeef> You could make a macro like `proc doThing(a1: Task) {.rtosProc.}` which emits a `let a1 = cast[ptr Task](a1)` and adds `cdecl` to the procedure to make it a bit cleaner but ymmv 🙂 |
| 23:47:50 | girvo | Ohhh that's a good idea too |
| 23:48:28 | girvo | I plan on doing my best to make working with FreeRTOS in ESP32 as nice as possible in Nim land lol |
| 23:48:43 | FromDiscord | <Elegantbeef> Then that macro sounds pretty nice 🙂 |
| 23:48:44 | girvo | Because doing it in straight C is painful at best |
| 23:49:58 | girvo | Interesting, it created the task! and it ran! once lol. I gotta have a look at what it's doing, likely my destructor/scoping causing it to delete itself I reckon |
| 23:50:49 | girvo | Hahaha yeah |
| 23:51:14 | girvo | I gotta brush up on scoping in Nim with ARC nowadays |
| 23:52:31 | girvo | https://pastebin.com/aqqMUXgd that's the main.nim app code |
| 23:52:53 | girvo | https://pastebin.com/qqy97X0P |
| 23:52:59 | girvo | xTaskCreate wrapper |
| 23:53:25 | girvo | Despite the while true: in the cb proc, it amusingly runs once then `=destroy` is called |
| 23:53:36 | girvo | Because I'm definitely misunderstanding how one should approach this ;) |
| 23:54:24 | FromDiscord | <Elegantbeef> At the end of `appMain` it'll destroy `task` |
| 23:54:38 | nrds | <Prestige99> Is there a non-reentrant lock in the stdlib? |
| 23:56:02 | girvo | Yeah. I gotta look into FreeRTOS and work out how the "main thread" stuff works. I could put a while true in app_main as well, though I remember FreeRTOS saying not to? |
| 23:57:19 | girvo | Hah yeah. A simple white true: triggers the FreeRTOS task watchdog |
| 23:57:30 | girvo | Time to go look at some documentation I think |
| 23:58:05 | girvo | I suppose I could skip the RAII-like destructor and just make it an explicit delete proc on the task object for now |
