| 00:01:28 | FromDiscord | <Technisha Circuit> Thanks |
| 00:04:14 | FromDiscord | <k1tt3hk4t> Should I assume that using dealloc on a null pointer is safe, as it is in C? |
| 00:04:26 | Yardanico | no |
| 00:04:56 | FromDiscord | <k1tt3hk4t> gotcha' |
| 00:06:17 | Yardanico | you can check memory alloc stuff in https://github.com/nim-lang/Nim/blob/master/lib/system/alloc.nim https://github.com/nim-lang/Nim/blob/master/lib/system/osalloc.nim |
| 00:06:23 | Yardanico | there are also other files probably |
| 00:06:37 | Yardanico | (by default Nim has it's own allocator which uses OSes memory allocation APIs directly) |
| 00:07:11 | Yardanico | ah wait wrong branch |
| 00:07:42 | Yardanico | https://github.com/nim-lang/Nim/blob/devel/lib/system/alloc.nim https://github.com/nim-lang/Nim/blob/devel/lib/system/osalloc.nim https://github.com/nim-lang/Nim/blob/devel/lib/system/memalloc.nim |
| 00:08:13 | FromDiscord | <k1tt3hk4t> thanks for sourcing your answer |
| 00:09:54 | Yardanico | you might also like to read https://nim-lang.org/docs/intern.html and https://nim-lang.org/docs/destructors.html |
| 00:11:08 | Yardanico | although some stuff in intern doesn't really apply to arc and friends |
| 00:11:19 | Yardanico | e.g. --gc:arc doesn't really have RTTI |
| 00:13:18 | FromDiscord | <Shucks> https://paste.sh/en44Pq-B#bIRvQaEWy-Gr3u5Fu63DuxHA |
| 00:13:29 | Yardanico | ? |
| 00:13:50 | FromDiscord | <Shucks> im a bit confused. I've tried to reproduce that issue on the nimplayground and the arrays get casted to the correct strings |
| 00:14:09 | Yardanico | can you show the code? |
| 00:14:21 | Yardanico | I mean to the example to compile :P |
| 00:14:41 | FromDiscord | <Clyybber> > I guess I should make yet another gource video for nim↵hell yeah :D |
| 00:16:20 | FromDiscord | <Shucks> like that? https://play.nim-lang.org/#ix=2q12 However like i've said i can't reproduce that issue. But somehow im getting weird results casting char arrays into strings |
| 00:16:34 | Yardanico | can you try casting to cstring instead? |
| 00:17:00 | Yardanico | like https://play.nim-lang.org/#ix=2q13 |
| 00:20:13 | FromDiscord | <Shucks> Works perfectly fine. What exactly happens |
| 00:20:54 | * | marquisdefalbala quit (Quit: Konversation terminated!) |
| 00:20:59 | Yardanico | cstring is a string with a null terminator |
| 00:21:08 | Yardanico | I'm not sure if memory leaks or not though :D but it shouldn't I guess |
| 00:21:59 | FromDiscord | <Shucks> Great thank you 🙂 |
| 00:22:59 | FromDiscord | <Technisha Circuit> https://github.com/rnowley/nim-ncurses isn't working in Nim 1.2.0 :/ |

| 00:28:03 | Yardanico | haha nico go brrr https://i.imgur.com/75cpyNU.png |

| 00:32:05 | Yardanico | r/place had it's own palette of 16 colors |
| 00:32:09 | Yardanico | I just made a GPL palette for nico |
| 00:32:12 | Yardanico | with same colors |
| 00:32:24 | Yardanico | yes there are only 16 colors in that picture really |

| 01:09:29 | Yardanico | @ikrima you mean the generic type? |
| 01:09:38 | Yardanico | so you want to get NodeBase ? |
| 01:09:44 | FromDiscord | <ikrima> @Yardanico yeah |
| 01:09:59 | FromDiscord | <ikrima> i want to get the `T` out of `seq[T]` |
| 01:10:01 | Yardanico | try https://nim-lang.org/docs/typetraits.html#genericParams.t%2Ctypedesc |
| 01:10:19 | leorize | @ikrima: in Nim lingo those are generics :P |
| 01:10:28 | Yardanico | ah I think it won't work with typeof |
| 01:10:44 | Yardanico | there was another way iirc |
| 01:12:02 | FromDiscord | <ikrima> @Yardanico I've tried `genericParams` but can't get that to work either (complains that its an invalid expression) |
| 01:12:09 | Yardanico | yeah I forgot about that |
| 01:13:00 | leorize | @ikrima can you create a small example on the playground? |
| 01:13:18 | Yardanico | leorize: https://play.nim-lang.org/#ix=2q19 |
| 01:13:31 | Yardanico | genericParams only works with literals |

| 02:03:49 | Yardanico | just use a websocket lib? |

| 03:02:08 | Yardanico | yes |
| 03:02:09 | Yardanico | its not nim |
| 03:02:11 | FromDiscord | <Zed> it looks beautiful |
| 03:02:15 | FromDiscord | <Zed> functional |
| 03:02:27 | FromDiscord | <Zed> powerful |
| 03:02:38 | FromDiscord | <Zed> it's what nim was missing all along |
| 03:02:45 | Yardanico | no |
| 03:02:54 | FromDiscord | <Zed> you just cant escape the braces |
| 03:03:03 | FromDiscord | <Zed> embrace the change |
| 03:04:12 | FromGitter | <ynfle> Speaking of functional... Yardanico, `toSeq(strTable.pairs).toTable` |
| 03:04:22 | Yardanico | but that's probably not very efficient :P |
| 03:04:29 | FromGitter | <ynfle> Why? |
| 03:04:34 | Yardanico | because you're creating copies |
| 03:04:42 | Yardanico | i mean more copies |
| 03:04:53 | * | endragor joined #nim |
| 03:04:54 | Yardanico | you copy the entire string table into a sequence, then make a table out of it |
| 03:06:22 | Yardanico | but yeah it's okay |
| 03:09:44 | FromGitter | <ynfle> Thanks for the validation |
| 03:10:22 | FromGitter | <ynfle> It's just once for JSON |
| 03:27:23 | FromDiscord | <Technisha Circuit> > unless you use a nimbraces -> nim transpiler and tabs instead of spaces :P↵Nimbraces? |
| 03:28:59 | FromDiscord | <KingDarBoja> Nim with {} |
| 03:31:12 | FromDiscord | <k1tt3hk4t> Are Nim destructors defined for pointers? I would expect it to call destroy on the pointed-to thing then also run dealloc on the pointer, but I'm not sure if this is actually the case |
| 03:31:12 | FromDiscord | <Technisha Circuit> Oh? |
| 03:31:47 | Yardanico | @k1tt3hk4t you need an object which wraps the pointer then |
| 03:31:47 | FromDiscord | <Technisha Circuit> So I could use braces instead of indents? |
| 03:31:48 | Yardanico | I think |
| 03:31:53 | FromDiscord | <k1tt3hk4t> hm ok |
| 03:32:08 | Yardanico | "ref" pointers are automatically managed |
| 03:32:16 | Yardanico | ptr/pointer are not managed at all |
| 03:32:28 | Yardanico | so yeah, just create an object which wraps your own pointer if you wish to wrap some pointer |
| 03:33:05 | FromDiscord | <k1tt3hk4t> gotcha |

| 04:15:16 | Yardanico | why |
| 04:15:28 | Yardanico | why are you suddently switching to js backend again |
| 04:15:43 | FromDiscord | <Technisha Circuit> Because my friend TwT |
| 04:15:46 | Yardanico | what? |
| 04:15:52 | Yardanico | tell him to compile JS to native code instead |
| 04:16:04 | FromDiscord | <Technisha Circuit> What? |
| 04:16:16 | Yardanico | tell him to learn nim |
| 04:16:20 | FromDiscord | <Technisha Circuit> Okay |
| 04:16:37 | FromDiscord | <Technisha Circuit> :p |
| 04:17:07 | Yardanico | but generally there's nothing difficult in replicating that JS code |
| 04:17:14 | Yardanico | just define nim procs which will be imported from js |
| 04:18:05 | Yardanico | e.g. https://nim-lang.org/docs/jsffi.html#require%2Ccstring |
| 04:20:32 | shashlick | @Synth - okay pushed |
| 04:21:42 | Yardanico | @Technisha it's really easy to do, something like https://play.nim-lang.org/#ix=2q1D although I didn't test it |
| 04:21:46 | Yardanico | just skimmed through jsffi |
| 04:22:22 | Yardanico | seems to work actually |
| 04:23:17 | Yardanico | just tested locally |
| 04:23:40 | Yardanico | works just fine, used a nim websocket lib to connect as a client |
| 04:23:44 | Yardanico | to nodejs running this |
| 04:23:54 | Yardanico | but you have to remember - Nim's JS backend is NOT for NodeJS |
| 04:23:55 | Yardanico | it's for browsers |
| 04:27:13 | FromDiscord | <Technisha Circuit> Oh cool |
| 04:27:35 | FromDiscord | <Technisha Circuit> But doesn't any Nim generated JS work in NodeJS too? |
| 04:27:40 | * | marnix joined #nim |
| 04:27:46 | FromDiscord | <Technisha Circuit> And isn't there also a NodeJS flag? |
| 04:27:51 | Yardanico | it does, I tested in NodeJS, but you'll have to map a lot of nim stuff to NodeJS manually |
| 04:28:00 | Yardanico | yes, but as I said - NodeJS support is there just for the tests |
| 04:28:17 | Yardanico | you'll have to wrap even simplest stuff as stdin/stdout/file reading/writing, as those are not mapped to nodejs |
| 04:29:08 | FromDiscord | <Synth> Thank you shashlick! |
| 04:29:52 | FromDiscord | <Technisha Circuit> Oh okay |

| 06:15:42 | disbot | ➥ getCustomPragma is split up in more usable chunks |
| 06:16:02 | FromDiscord | <Elegant Beef> yea i dont need it im just talking about ways we can annotate in nim similar to C# |
| 06:16:08 | Yardanico | pragmas |
| 06:16:15 | Yardanico | check https://github.com/Yardanico/telenim/blob/master/src/telenim/types.nim |
| 06:16:29 | Yardanico | (be careful, it's 14k loc) |
| 06:16:41 | FromDiscord | <Elegant Beef> Yea i know, just wanted a visible version |
| 06:16:51 | Yardanico | well in https://github.com/Yardanico/telenim/blob/master/src/telenim/json_custom.nim at the bottom there's a small test |
| 06:18:26 | Yardanico | https://play.nim-lang.org/#ix=2q1R |
| 06:20:02 | FromDiscord | <Elegant Beef> Thanks |
| 06:20:36 | FromDiscord | <Elegant Beef> Ooh the object variance usage is nice |
| 06:22:34 | FromDiscord | <Elegant Beef> And that reminded me i needed to updoot the RFC for object variances 😄 |
| 06:22:57 | Yardanico | you mean the shared fields one? which variant (pun not intended) of implementation you prefer? |
| 06:23:28 | FromDiscord | <Elegant Beef> The modification of case inside of object |
| 06:23:33 | Yardanico | ? |
| 06:23:52 | Yardanico | https://github.com/nim-lang/RFCs/issues/19#issuecomment-173529871 or https://github.com/nim-lang/RFCs/issues/19#issuecomment-633684323 |
| 06:23:52 | disbot | ➥ Allow usage of the same attribute name in different branches within variant types |
| 06:24:25 | Yardanico | I don't think the one in the issue body itself will be approved :) |
| 06:24:51 | FromDiscord | <Elegant Beef> the one 4raq suggested |
| 06:24:55 | Yardanico | yeah it's nice |
| 06:25:20 | FromDiscord | <Elegant Beef> Well write less code not more, especially when more just is redundant |
| 06:25:46 | FromDiscord | <Elegant Beef> i'd even wager just stop using the `word` case inside object and use `variant` |
| 06:25:58 | FromDiscord | <Elegant Beef> (edit) '`word` case' => 'word `case`' |
| 06:25:59 | FromDiscord | <Elegant Beef> Im tired |
| 06:26:00 | FromDiscord | <Elegant Beef> 😄 |
| 06:26:11 | Yardanico | lol |
| 06:26:50 | FromDiscord | <Elegant Beef> I only say that so it's more verbose and less "why is there a case statement that fires for multiple things" |
| 06:27:08 | Yardanico | well it means introducing yet another keyword :P |
| 06:28:17 | FromDiscord | <Elegant Beef> shhh |
| 06:28:31 | Yardanico | the last keyword change was 3 years ago https://github.com/nim-lang/Nim/commit/cae5e33a4a66406813769361233438c7d2df6009 |

| 07:07:08 | FromDiscord | <Rika> doesnt that still require an init(Weave)? |
| 07:07:15 | Yardanico | why? |

| 08:03:10 | FromDiscord | <Yardanico> For a start we might have Chinese, Spanish, Russian, maybe some European ones like German, French? |

| 08:03:45 | skrylar[m] | i had the realization earlier when looking at using zeromq for something in nim... mostly that if you don't care about most of the stuff in http, you can actually use http to control stuff with not really that much code :think: |

| 08:04:11 | FromDiscord | <Yardanico> Well the thing is that there's a lot of languages :) |
| 08:04:34 | FromDiscord | <Yardanico> I think the max limit would be 10 |
| 08:04:48 | FromDiscord | <Yardanico> 10 language specific channels |
| 08:05:21 | FromDiscord | <Elegant Beef> I'll say do it |
| 08:05:56 | FromDiscord | <Elegant Beef> Only if you make the category named "Dirty Foreigners" 😛 |
| 08:06:37 | FromDiscord | <impbox> any reason to not just have non-english chat in the appropriate channel for topic rather than language based? |

| 08:08:03 | skrylar[m] | if i just started babbling away in gaelic the room looks busy but it doesn't help most anone here |
| 08:08:13 | FromDiscord | <impbox> if someone asks a question here in language X, someone else who understands language X can respond. |
| 08:08:15 | skrylar[m] | although if this was zulip you'd just put the language code in your topic and people could ignore or read it /shrug |
| 08:08:34 | FromDiscord | <Elegant Beef> Well an issue will arise that english people are going to make the questions fade away |
| 08:08:35 | FromDiscord | <impbox> sure not everyone will understand |
| 08:08:45 | FromDiscord | <Elegant Beef> They will obviously be less trafficked but could be more helpful |
| 08:08:55 | FromDiscord | <impbox> that's a fair point @Elegant Beef |
| 08:09:15 | skrylar[m] | altho depending on where the server is i'm not sure "our mods don't speak that language" is a valid defense |
| 08:09:25 | FromDiscord | <impbox> even if english is not first language, people might still be able to help via translator assistance |

| 08:38:24 | PMunch | TBF, some of the characters Nim and other programming languages are pretty hard to reach on some keyboards |
| 08:39:50 | Tlanger | Maybe time for a new keyboard layout? |
| 08:40:11 | Tlanger | The next dvorak |
| 08:41:09 | FromDiscord | <Yardanico> So @narimiran what do you think about creating channels for other languages here in Discord? |
| 08:41:24 | narimiran | i don't have an opionion about it :) |
| 08:41:32 | FromDiscord | <Yardanico> Although I probably wouldn't map them to IRC since no one will use these IRC channels |
| 08:41:35 | FromDiscord | <Rika> i dont understand the hard to reach argument |
| 08:41:42 | PMunch | Tlanger, I actually did have numbers and symbols swapped on my keyboard before, but I couldn't quite get used to it.. |
| 08:42:02 | PMunch | Besides, some keys on Norwegian boards require AltGr to get to.. |
| 08:42:24 | PMunch | @Rika, what don't you understand about it |
| 08:42:36 | PMunch | Not all the symbols on your keyboard are as easy to reach as others |
| 08:42:38 | FromDiscord | <Rika> its misworded |
| 08:43:04 | FromDiscord | <Rika> its more of "the layers on my keyboard are different" then is it not |
| 08:43:16 | FromDiscord | <Rika> when i think of reach i think of physically reaching for a symbol |
| 08:43:33 | FromDiscord | <Rika> not requiring more modifiers to access the symbo |
| 08:43:35 | FromDiscord | <Rika> l |
| 08:44:08 | PMunch | Eh, hard to type then I guess |
| 08:45:06 | * | casaca quit (Remote host closed the connection) |
| 08:48:48 | FromDiscord | <KrispPurg> I think creating channels for other languages is good. |
| 08:50:54 | PMunch | Hmm, anyone wants to modify this script to output the valid ranges of colours? Would be cool to be able to visually see what colours are available to be able to pick one: https://github.com/github/linguist/blob/master/test/test_color_proximity.rb |

| 08:51:09 | disbot | ➥ Change Nim's colour to better match the logo |
| 08:53:17 | FromDiscord | <KrispPurg> Why isn't the new Nim colour on GitHub yet? |
| 08:53:56 | PMunch | Read the last couple comments on the PR |
| 08:54:30 | PMunch | Basically another language named Daphne got a colour that crashes with the new Nim one before the Nim PR was accepted |
| 08:54:36 | PMunch | So it got rolled back |
| 08:54:55 | Zevv | Hey that's the color of my bikeshed |
| 08:55:04 | PMunch | Zevv, hahaha :P |
| 08:55:12 | FromDiscord | <Yardanico> Yeah, I then found a couple of a bit similar good colors |
| 08:55:24 | FromDiscord | <Yardanico> But then some people started saying they don't want the change |
| 08:55:37 | FromDiscord | <Yardanico> So I kinda thought it's not needed |
| 08:55:45 | FromDiscord | <KrispPurg> Oh ;-; |
| 08:56:06 | FromDiscord | <Recruit_main707> it could be nice, but i dont think they would really be used |

| 08:58:38 | narimiran | #keepNimGreen |
| 08:59:28 | PMunch | Why should it be green though? |
| 09:00:47 | FromDiscord | <Yardanico> Because a GitHub employee in 2012 decided that it should be green |
| 09:00:56 | FromDiscord | <Yardanico> And people are "used to the current color" |
| 09:02:00 | PMunch | I know why it is green, but why do people want to keep it green? |
| 09:02:02 | FromDiscord | <Recruit_main707> its not the best, (but it could be worse) |
| 09:02:22 | FromDiscord | <Recruit_main707> i do think it should be changed to something more fitting |
| 09:02:47 | FromDiscord | <Recruit_main707> a nice deep dark blue for example |
| 09:03:00 | FromDiscord | <Rika> ~~new color too close to js~~ |
| 09:04:29 | FromDiscord | <Vindaar> the fact that nim is green will guarantee nim will become the dominant language in our sustainable "everything is green" future! |

| 09:12:48 | FromDiscord | <KrispPurg> Huh. |
| 09:15:00 | PMunch | Hmm, I have a guy at work who's maintaining some firmware for the PortaPack(HackRF) project. He asked me if it was possible to use Nim to help with how tedious it is to create new "apps" for it as that currently requires edits to multiple files to add in graphics and CMake entries. Have anyone done something like this before? |
| 09:15:46 | PMunch | Like create a small wrapper that replaces all the logic in a CMake file in Nim, and use compile-time features to read through files and folders to automatically add stuff. |
| 09:17:53 | FromDiscord | <Yardanico> Well there's Nake |
| 09:18:03 | FromDiscord | <Yardanico> But it compiles a native binary which then does the stuff |
| 09:18:14 | * | casaca joined #nim |
| 09:18:34 | PMunch | Yeah, another build tool isn't really solving anything :P |
| 09:19:08 | PMunch | This is what adding an app looks like now: https://github.com/eried/portapack-mayhem/commit/e43f8148610a40df0d01864d7fa825759fa75c4c |

| 09:21:12 | PMunch | As you can see, adding some stuff in CMake files, adding graphics as a C++ array into a file, adding references to it in the navigation part, etc. |
| 09:22:07 | PMunch | Basically he would want to rewrite the parts of the program that are just listings of stuff in Nim, to have it do it automatically, and then have Nim build the whole thing. |

| 09:26:27 | pietroppeter | @PMunch and @Yardanico : I did implement in Nim the color distance used in linguist color proximity test, but I got stuck while trying to reproduce the failing test between Dafny and Nim. Here is a repo with my implementation. The idea was, once I can reproduce color proximity to start from a color and find the closest that is valid for linguist. Here is my repo: https://github.com/pietroppeter/color_distance |

| 09:29:20 | * | lpirl joined #nim |
| 09:34:26 | PMunch | pietroppeter, it does produce a small difference for me between those colours |
| 09:36:06 | PMunch | Although the ones from the "color-proximity ruby gem README" fails |
| 09:36:36 | pietroppeter | ah yes, you are right. in fact rerunning nimble test that one goes ok. I think it is the actual value that was off (looking at the test failure probably I could find it) and that lead me to check against color-proximity |
| 09:36:54 | lpirl | Dear nim community. A beginner question: How would one implement monotonic tasks? I found asyncdispatch.addTimer which could maybe used, no? But looking at the source, this would drift, I guess. To avoid the drift, would one need to fiddle with absolute times and sleep timers manually? |
| 09:37:20 | pietroppeter | I did it a couple of weeks ago and I already forgot what was working and what not... |
| 09:37:47 | pietroppeter | I may have to check again |

| 13:19:16 | Zevv | where do I find authoritive documentation to throw at him |
| 13:20:42 | FromDiscord | <mratsim> Perdersen algorithm |
| 13:20:49 | FromDiscord | <mratsim> Lamport's Bakery algorithm |

| 13:21:07 | Zevv | nah, something simple and short that says "just don't do that" |
| 13:21:17 | FromDiscord | <mratsim> ah |
| 13:21:25 | Zevv | he's too high level schooled |
| 13:21:28 | FromDiscord | <mratsim> googling for "torn reads" might help |
| 13:21:44 | Zevv | thanks |
| 13:21:46 | FromDiscord | <mratsim> and also my talk |
| 13:21:50 | Zevv | haha :) |
| 13:22:00 | Zevv | It's a C++ discussion, but sure |
| 13:22:16 | * | thomasross quit (Ping timeout: 246 seconds) |
| 13:22:50 | FromDiscord | <mratsim> well the initial example I used was from C++ |
| 13:23:30 | Zevv | lemme check |
| 13:23:36 | FromDiscord | <mratsim> sent a code paste, see http://ix.io/2q3i |
| 13:23:53 | Zevv | yeah sure, but you're not authoritive are you :) |
| 13:24:03 | FromDiscord | <mratsim> you can have (1,0), (0, 1), (1, 1) |
| 13:24:10 | Zevv | to _me_ you are, though |
| 13:24:39 | FromDiscord | <mratsim> but you can also have (0, 0) because the compiler is free to reorder reads if there is no observable effect on the program semantics |
| 13:24:59 | Zevv | sure |
| 13:25:11 | FromDiscord | <mratsim> if you don't tell that you have sharing, by the use of critical sections or atomics, anything can happen |
| 13:27:15 | FromDiscord | <mratsim> In terms of authoritative, maybe there is a summary of Herb Sutter talk, weapons of Atomic<> destruction |
| 13:28:11 | Zevv | yeah, UB was my argument. I found that in my career I should either learn everything there is to know about this stuff to do it right, or just stick to one or two very simple rules. |
| 13:28:25 | Zevv | Don't share. Keeps your locks localized. |

| 13:43:36 | FromDiscord | <mratsim> That' why I have a couple of modules that are just glorified atomic int or atmoic pointers: https://github.com/mratsim/weave/blob/master/weave/cross_thread_com/scoped_barriers.nim#L57↵https://github.com/mratsim/weave/blob/master/weave/cross_thread_com/channels_spsc_single_ptr.nim#L45 |

| 13:48:25 | haxscramper | Under what conditions macro with `untyped` arguments might trigger `undeclared identifier` error? Error goes away if I define `const/var/let` with required name. And I'm failing to replicate the error with simple macro - it does not give any errors. |
| 13:55:57 | alehander92_ | you can use expandMacros |
| 13:56:04 | alehander92_ | to see what does it generate maybe |
| 13:56:22 | FromDiscord | <mratsim> everytime there is a semcheck error for whatever reason, macros with untyped parameter throws an undeclared identifier error unfortunately |
| 13:57:00 | FromDiscord | <mratsim> if you can't use expandMacros if the error is in the generated code, put "result.toStrLit" at the end of your code |
| 13:57:20 | FromDiscord | <mratsim> and replace the macro call with the expanded Nim code that is output |
| 14:13:12 | Zevv | well, in the end it was Ye Olde 'Prograaming with POSIX Threads" book from my bookshelf that had to make the final verdict on this. |
| 14:14:20 | * | PMunch quit (Quit: Leaving) |
| 14:19:03 | alehander92_ | you didnt fight with books did ya |
| 14:25:05 | Zevv | Well, the fun part is that some time ago I was moving rooms and wanted to get rid of some books. So I put a picture of my bookshelf on the company slack, and got laughed at |
| 14:25:08 | Zevv | But here we are |
| 14:25:36 | Zevv | And I was always refusing to use threads, and they found me a bit of a whiner. |
| 14:25:43 | Zevv | so I must admit, this feels good :) |
| 14:27:21 | FromDiscord | <Zachary Carter> @mratsim - I'm read through that markdown document you shared with me about messing with vtables to satisfy C++ pure virtual function classes, but I don't know if it will help me with what I'm trying to do. In fact I'm kind of stuck as far as how to proceed. |
| 14:28:11 | FromDiscord | <Zachary Carter> https://github.com/mosra/magnum-examples/blob/master/src/triangle/TriangleExample.cpp - is essentially what I need to produce in Nim |
| 14:28:57 | FromDiscord | <Zachary Carter> https://github.com/mosra/magnum/blob/master/src/Magnum/Platform/Sdl2Application.h#L432-L1218 - is the class that class inherits from |
| 14:29:17 | FromDiscord | <Zachary Carter> so there are a few virtual methods that need overrides but I also need to implement a constructor |
| 14:41:48 | Zevv | mratsim: where was this list of weave-vs-the-rest-of-the-world performance? |
| 14:52:15 | FromDiscord | <Zachary Carter> so if I emit a C++ class and it defines a constructor - is there any way I can implement it in Nim or do I need to implement it in C++? |
| 14:52:40 | FromDiscord | <Zachary Carter> I guess the easy thing to do would be to just have a constructor that calls some Nim proc to initialize everything |

| 18:31:04 | leorize | if your object requires initialization, you can use `{.requireInit.}` on the type to ensure that the object must be created via a full construction |

| 18:45:47 | FromDiscord | <treeform> bung, I don't have a way to create new fonts. If you going to create new fonts I recommend making .svg fonts as they are much simpler format. Then use tools like fontforge to make it into a ttf. |
| 18:46:10 | FromDiscord | <treeform> bung, you can extract parts of glyphs though. That is not a problem. |
| 18:46:18 | leorize | isn't svg font a tiny bit worse because you can't do hinting on them? |
| 19:01:34 | FromDiscord | <treeform> I don't think ppl care about hinting with high dpi screens. |

| 22:00:08 | FromDiscord | <Generic> but once you throw these into the mix accessing the global variable will be more expensive |
| 22:00:25 | FromDiscord | <Generic> if you pass in a local variable you're essentially passing a pointer |
| 22:00:38 | FromDiscord | <Generic> which needs to come from somewhere as well |
| 22:01:07 | * | thomasross joined #nim |
| 22:01:08 | FromDiscord | <Generic> so if you then just pass in a global variable, it's the exact same cost |
| 22:02:09 | FromDiscord | <Generic> or slightly more costly |

| 22:29:24 | shashlick | ok ran some tests, not too specific but didn't see any noticeable difference |
| 22:34:21 | FromDiscord | <Shucks> So I'm able to cast procs into pointers. But how would I cast them back? |
| 22:35:49 | FromDiscord | <Rika> you'll need to know what kinda proc they are, then you cast with `cast[proc (args): rettype](theptr)` and replace args and rettype as needed |
| 22:38:01 | FromDiscord | <Shucks> for example `proc foo = echo "Hello"` |
| 22:38:09 | Yardanico | yes? |
| 22:38:11 | FromDiscord | <Shucks> no args and no return value. `proc` should be enough |
| 22:39:01 | Yardanico | not exactly |
| 22:40:10 | FromDiscord | <Shucks> mh? |
| 22:40:49 | Yardanico | the best way is |
| 22:41:16 | Yardanico | cast[typeof(myproc)](cast[pointer](myproc)) |
| 22:41:23 | Yardanico | to not specify type yourself |
| 22:41:58 | Yardanico | otherwise |
| 22:42:04 | Yardanico | if you have "p" as a pointer to the normal proc |
| 22:42:11 | Yardanico | cast[proc () {.nimcall.}](p)() to run it |
| 22:42:25 | Yardanico | nimcall is needed because otherwise the compiler will assume you're trying to cast to a closure |
| 22:42:43 | FromDiscord | <Shucks> ❤️ |
| 22:42:45 | FromDiscord | <Shucks> sent a code paste, see http://ix.io/2q5W |
| 22:42:57 | FromDiscord | <Shucks> Once again thank you lol |
| 22:52:10 | Yardanico | don't forget that casting closures is much harder though |
| 22:52:23 | Yardanico | and generally you rarely need to cast procs to pointers unless you do C ffi or for some reason need type erasure |
| 22:52:34 | Yardanico | ah wait wrong term |

| 22:59:30 | * | dddddd_ is now known as dddddd |
| 23:03:20 | FromDiscord | <gokr> In wrapping ORX I have stumbled upon a bunch of struct types that have anonymous unions in them. Is there a strategy for how to deal with this in Nim? |
| 23:04:16 | Yardanico | doesn't c2nim handle that? |
| 23:04:25 | Yardanico | i think it does |
| 23:04:46 | FromDiscord | <gokr> Well, it gives them names like `ano_blabla_120` etc |
| 23:04:56 | Yardanico | well yes but you can just rename |
| 23:05:21 | FromDiscord | <gokr> But... in C AFAIK an anonymous union in a struct makes the members of the union accessible in the struct. |
| 23:06:36 | FromDiscord | <lqdev> that's not really possible in Nim |
| 23:06:44 | FromDiscord | <lqdev> the whole object would have to be a union |
| 23:06:51 | FromDiscord | <gokr> So in C - one can then write `myStruct.oneOfTheUnionMembers`. But in c2nim code it turns into `myStruch.x.oneOfTheUnionMembers`. |
| 23:07:16 | Yardanico | well yes |
| 23:07:20 | Yardanico | Nim doesn't claim to be C |
| 23:07:27 | FromDiscord | <lqdev> and c2nim has no way of knowing whether the union is tagged or not so it can't make a case object |
| 23:07:32 | Yardanico | you can always make templates |
| 23:07:34 | Yardanico | and macros |
| 23:07:41 | Yardanico | to achieve same code as in C for this case if you want |
| 23:07:55 | shashlick | @gokr did you see the nimterop wrapper |
| 23:08:08 | Yardanico | shashlick: how does it handle anonymous structs? |
| 23:08:16 | FromDiscord | <gokr> I haven't yet looked much at it, no. |
| 23:08:19 | Yardanico | embeds them in the same type? |
| 23:10:06 | shashlick | Nim doesn't support that |
| 23:10:16 | shashlick | I have to create names too |

| 23:57:38 | Yardanico | ?? |
| 23:57:47 | Yardanico | can you explain |
| 23:57:49 | FromDiscord | <ikrima> (playground sample: https://play.nim-lang.org/#ix=2q1d) |

| 23:58:43 | leorize | since it's fully macro based you can just grab the code and change the names |
| 23:59:06 | leorize | (or not and just gate it behind a conditional for Nim < 1.3.5) |
