| 00:00:01 | FromDiscord | <Gyllou> sry for pic spam |
| 00:00:11 | FromDiscord | <nikki> yo i didn't realize nim had a documentation website |
| 00:00:37 | FromDiscord | <Gyllou> are you being facetious? |
| 00:00:45 | FromDiscord | <nikki> yeah sorry lol i'm in friday silly mode |
| 00:00:50 | PMunch | @InventorMatt, well that's not good. But I think you might just be running into byte ordering |
| 00:01:04 | FromDiscord | <nikki> it happens between 3pm and 2am on fridays |
| 00:01:16 | FromDiscord | <Gyllou> lol kk i know im a nim noob just trying to link for that guy asking |
| 00:01:25 | FromDiscord | <Gyllou> metoo, im slightly drunk too |
| 00:01:39 | FromDiscord | <nikki> oh no hard feelings at all. it's great that this community is generally kinda nice and helpful to each other |
| 00:01:49 | FromDiscord | <nikki> that's one thing that i immediately felt when i got on this discord |
| 00:01:57 | PMunch | Binaryparse is strictly big endian IIRC |
| 00:02:04 | FromDiscord | <Gyllou> friday is my paper reading day so i usually get tired of that and start drinking wine at like 3pm |
| 00:02:13 | disruptek | i feel like we could totally smoke the competition with a proper graph library. |
| 00:02:16 | FromDiscord | <nikki> newspaper or like academic papers |
| 00:02:25 | FromDiscord | <Gyllou> i agree disruptek |
| 00:02:28 | FromDiscord | <Gyllou> academic papers |
| 00:02:32 | disruptek | like, it's not hard to make really fast code in nim. we have the right level of abstraction for it. |
| 00:02:39 | FromDiscord | <InventorMatt> PMunch, when I do a manual approach to check it I am able to get the right result. I wonder what I may be doing wrong with your lib then |
| 00:02:43 | FromDiscord | <Gyllou> im aiming for totem level performance but thats a long way off |
| 00:02:54 | FromDiscord | <nikki> http://shape-of-code.coding-guidelines.com/2020/11/08/evidence-based-software-engineering-book-released/ this thing was posted on the webz recently if u want sth to read |
| 00:02:57 | PMunch | Cheers Gyllou, I'm sitting here sipping a drink :) |
| 00:03:12 | FromDiscord | <Gyllou> its friday ya'll, gotsta |
| 00:03:12 | disruptek | its been a few years since i did graph stuff but it's central to my startup, so i am down to do some heavy lifting. |
| 00:03:20 | FromDiscord | <nikki> yeah i think nim can make anything as fast as you want. like there are no limits. bc you can literally generate or compile against whatever |
| 00:03:29 | FromDiscord | <nikki> and the normal code you write just is good |
| 00:03:43 | FromDiscord | <nikki> like what it generates to |
| 00:03:56 | disruptek | i am counting on cps for threading the algos. |
| 00:03:57 | FromDiscord | <nikki> except some times when i iterate through hash tables and it copies the entries out 😐 |
| 00:04:03 | FromDiscord | <Gyllou> yea its very nice to change it up |
| 00:04:07 | FromDiscord | <nikki> i wish it just was a compile error to copy anything |
| 00:04:11 | planetis[m] | Hes dtg |
| 00:04:15 | disruptek | i mean, it can be. |
| 00:04:19 | planetis[m] | Down to graph |
| 00:04:46 | FromDiscord | <Gyllou> we have a speech module called phonographica we built in python, i'd love to port it over one day as well |
| 00:04:56 | disruptek | skiplists is >2.5x faster under arc. just a cli switch and boom. |
| 00:05:39 | FromGitter | <jrfondren> for my part I'm replacing various Rust and D utilities with Nim. It's very satisfying. |
| 00:05:50 | disruptek | what kinda utilities? |
| 00:05:52 | FromDiscord | <nikki> i think the right way to do that is to keep writing macros until you can just compile the python code you wrote; with nim |
| 00:05:54 | FromDiscord | <Gyllou> i have no desire to write an audio package for nim though. port audio is miserable to work with too |
| 00:05:59 | PMunch | InevntorMatt, could you try to call one of the `swapEndian` procedures from here on your number? https://nim-lang.org/docs/lib.html |
| 00:06:07 | PMunch | Woops, wrong link: https://nim-lang.org/docs/endians.html |
| 00:06:10 | FromDiscord | <nikki> for audio for the game i'm thinking about using soloud |
| 00:06:16 | FromDiscord | <nikki> mostly cuz i want it to work out of the box in emscripten too |
| 00:06:24 | * | sagax quit (Ping timeout: 260 seconds) |
| 00:07:18 | FromGitter | <jrfondren> CGI scripts, log mungers, some small UDP and TCP servers. nothing too big of a deal. |
| 00:08:20 | FromDiscord | <Gyllou> i might look at soloud, but even still the main dependencies are a TF type lib and deepspeech interface |
| 00:08:41 | FromDiscord | <Gyllou> though come to think of it i vaguely remember some deepspeech nim package, idk |
| 00:09:39 | FromGitter | <jrfondren> https://github.com/jrfondren/chrestomathy/tree/master/pwcheck is actually one of them |
| 00:12:57 | FromDiscord | <InventorMatt> Pmunch: what would I put for the other pointer? also while iterating through the tuple it gives me I am able to echo the values correctly and calling type on them works but any other function called on them and it points back to the tuple itself not the value |
| 00:14:08 | PMunch | Hmm, do you have an example of your code? |
| 00:15:28 | * | astronavt quit (Remote host closed the connection) |
| 00:16:00 | PMunch | Depends on what you want for how to use endians |
| 00:16:12 | * | astronavt___ joined #nim |
| 00:16:31 | PMunch | Here's an example: https://play.nim-lang.org/#ix=2E4r |
| 00:16:44 | FromDiscord | <InventorMatt> yes, I do. i have the full everything in the github issue but here is the code https://play.nim-lang.org/#ix=2E4q |
| 00:19:21 | PMunch | And the problem is? |
| 00:19:30 | PMunch | Hard to tell without knowing the content of that file |
| 00:20:44 | FromDiscord | <InventorMatt> https://figshare.com/articles/dataset/NEON_Teaching_Data_LiDAR_Point_Cloud_las_Data/4307750 |
| 00:20:49 | FromDiscord | <InventorMatt> here is the file |
| 00:21:06 | FromDiscord | <InventorMatt> https://www.asprs.org/wp-content/uploads/2010/12/LAS_1_4_r13.pdf here is the spec |
| 00:21:43 | FromDiscord | <InventorMatt> the id parameter should be 101 but instead i am getting 25856 |
| 00:22:06 | PMunch | Yeah, that's big vs. little endian |
| 00:22:39 | PMunch | From that spec you linked: [A note on Bit Fields – The LAS storage format is “Little Endian.” This means that multi-byte data fields are stored in memory from least significant byte at the low address to most significant byte at the high address. |
| 00:23:03 | mipri | !eval echo (0x6500, 0x0065) |
| 00:23:06 | NimBot | (25856, 101) |
| 00:23:07 | PMunch | And binaryparse is Big Endian, meaning you need to swap the endianess of any field with more than one byte |
| 00:23:40 | FromDiscord | <InventorMatt> is there a way to change that for the parser or will just have to iterate through the result and do the swap there? |
| 00:24:04 | PMunch | You just need to do it whenever you use the fields |
| 00:24:17 | PMunch | Well, you could define your own parser that does it automatically |
| 00:25:46 | FromDiscord | <InventorMatt> okay, thanks for the help. |
| 00:25:52 | PMunch | No problem |
| 00:26:19 | PMunch | I was thinking of adding byte ordering to binaryparse, but I remember I had a reason that made me not do it.. |
| 00:26:48 | * | astronavt___ is now known as astronavt |
| 00:27:10 | FromDiscord | <InventorMatt> so it won't be seen as a feature in the future then? |
| 00:27:12 | FromDiscord | <Avatarfighter> Yo yo yo everyone how is everyone 😄 |
| 00:27:12 | mipri | you thought that virtually all portable formats are big endian anyway? |
| 00:27:13 | disruptek | improper byte ordering can yield indigestion; it was probably that. |
| 00:27:37 | PMunch | mipri, might've been :P |
| 00:27:51 | PMunch | But I remember i wanted to add support for it |
| 00:28:03 | mipri | the swapEndian* API might also have been harder to apply than libc ntohs/ntohl functions |
| 00:28:14 | PMunch | There is even procedures implemented for reading/writing the different endians |
| 00:28:50 | PMunch | InventorMatt, I might add it, but if you want to add it feel free :) |
| 00:29:06 | PMunch | I have no specific plans for adding it, but I agree that it would be useful |
| 00:30:07 | FromDiscord | <InventorMatt> i'll look through the code more and see how simply it could be done. it is a pretty dense macro in there so I don't know much i would want to mess with that |
| 00:30:46 | PMunch | Haha, yeah it's not the prettiest code.. |
| 00:31:25 | * | astronavt quit (Remote host closed the connection) |
| 00:32:41 | mipri | https://play.nim-lang.org/#ix=2E4u |
| 00:32:45 | FromDiscord | <InventorMatt> is it in the getinfo where the endianeness would be or could point me to the main proc for this part of it? |
| 00:34:29 | PMunch | Oh wow, this is even worse than I remember.. |
| 00:35:42 | FromDiscord | <VideoCarp> does Nim have any GUI packages other than IUP bindings? |
| 00:36:13 | mipri | nimble search gui |
| 00:36:43 | FromDiscord | <VideoCarp> will try that |
| 00:37:22 | PMunch | InventorMatt, basically you want to add something to the format that allows you to specify endianess |
| 00:37:41 | FromDiscord | <VideoCarp> ah great thanks.↵is `nimble` basically the package manager? |
| 00:37:46 | mipri | yes |
| 00:38:38 | mipri | I haven't done any GUI stuff in Nim but looking around, nimqml looks interesting. |
| 00:38:42 | PMunch | Then you need to check info.size in createReadStatement and createWriteStatement and if it is a power of two and it was supposed to be the opposite endianess then use the other readData(LE|BE) function |
| 00:38:54 | PMunch | Some for writeData(LE|BE) |
| 00:39:11 | PMunch | wxnim also works fine @VideoCarp |
| 00:39:20 | PMunch | Has a neat little DSL as well |
| 00:40:00 | mipri | that's not in nimble search though :/ |
| 00:40:15 | FromDiscord | <InventorMatt> I'll look into doing that and see what can be done, thank PMunch |
| 00:40:56 | PMunch | No problem |
| 00:41:35 | FromDiscord | <shadow.> anyone know how to use winim? |
| 00:41:46 | FromDiscord | <shadow.> GetCursorPos is returning 0 every call |
| 00:41:49 | PMunch | Huh, I guess the original wxNim package might predate Nimble |
| 00:41:51 | PMunch | I'll add it |
| 00:43:53 | FromDiscord | <shadow.> nvm its bc i needed a POINT not an LPPOINT |
| 00:47:34 | PMunch | Hmm, I'll add it tomorrow |
| 00:47:37 | PMunch | It's getting late here |
| 00:55:48 | FromDiscord | <Daniel> sent a code paste, see https://play.nim-lang.org/#ix=2E4C |
| 00:57:49 | mipri | https://nim-lang.org/docs/assertions.html#assert.t,untyped,string |
| 00:59:12 | FromDiscord | <Daniel> i already read that, however i am still at basics, did reach to templates yet |
| 00:59:27 | mipri | then what are you asking? |
| 00:59:48 | FromDiscord | <Daniel> because i dont understand the explanation written on that link |
| 00:59:58 | mipri | ask a question about it, then |
| 01:00:21 | FromDiscord | <Daniel> what is assert used for? |
| 01:00:47 | PMunch | mipri, that was a discord bot code paste thing, it's a bit weird. But his question is in the "code" |
| 01:00:49 | mipri | enforcing invariants in debugging or assertion builds. |
| 01:01:23 | PMunch | Assert will basically quit out of your program if the check is false |
| 01:01:27 | mipri | https://www.sqlite.org/assert.html talks about assert in general |
| 01:01:41 | PMunch | An easy way to make sure that some value is something while debugging |
| 01:02:42 | PMunch | And you will see it quite often in examples because it shows what value is expected, and with Nims ability to check code example from the documentation when it's generated it will make sure the documentation generation fails if something returns the wrong value. |
| 01:02:48 | FromDiscord | <Daniel> so basicaly its true/false checkpoint i guess |
| 01:02:51 | mipri | the idea is, when writing something you'll think, "this is only true if X is the case", and you'll promise yourself that you'll make X always the case. Maybe you still have to ensure that elsewhere. Maybe that's definitely the case right now but modifications to the code have to maintain it, so you write a comment to effect of "make sure X is the case!" |
| 01:03:09 | mipri | and writing an assertion when you have such thoughts is a way of actually ensuring that X is really the case |
| 01:03:30 | FromDiscord | <shadow.> !eval echo cast[string]([97.byte, 97.byte]) |
| 01:03:33 | NimBot | Traceback (most recent call last)↵/usercode/in.nim(1) in↵SIGSEGV: Illegal storage access. (Attempt to read from nil?) |
| 01:03:37 | FromDiscord | <shadow.> f |
| 01:03:54 | PMunch | Daniel, yes pretty much |
| 01:03:59 | mipri | if it isn't, you have a bug, but because you made the assertion you have a quick failure at the point of X not being the case, rather than some potentially horrible behavior later on |
| 01:04:02 | FromDiscord | <shadow.> !eval var x: array[2, char] = [97, 97]; echo cast[string](x) |
| 01:04:04 | NimBot | Compile failed: /usercode/in.nim(1, 25) Error: type mismatch: got <array[0..1, int]> but expected 'array[0..1, char]' |
| 01:04:05 | PMunch | But when compiling with -d:release they will be removed |
| 01:04:24 | PMunch | If you need them in your release builds use `doAssert` instead |
| 01:04:27 | FromDiscord | <shadow.> !eval var x: array[2, char] = [97.chr, 97.chr]; echo cast[string](x) |
| 01:04:29 | NimBot | <no output> |
| 01:04:32 | mipri | shadow., a string is structurally equivalent to a seq[char], so there's a header, it's not just a bare array |
| 01:04:37 | FromDiscord | <shadow.> ahh ok |
| 01:04:49 | FromDiscord | <shadow.> im tryna figure out how to send 2 uint16's as a packet string lol |
| 01:04:54 | FromDiscord | <shadow.> ill figure it out |
| 01:05:08 | mipri | what you might find more convenient is casting 0-terminating that and casting it to a cstring, and then .string'ing that |
| 01:05:15 | FromDiscord | <shadow.> hmm ok |
| 01:05:33 | FromDiscord | <shadow.> because right now im just sending an array[4, byte] through `net` but i wanna convert to `netty` which only supports strings iirc |
| 01:05:36 | FromDiscord | <shadow.> (edit) "iirc" => "afaik" |
| 01:05:39 | PMunch | Use binaryparse :) |
| 01:05:44 | FromDiscord | <shadow.> smart |
| 01:06:12 | FromDiscord | <Daniel> thank you guys, i understand much better now....i just wish documentation would have been written more noob friendly :)↵Luckily, you guys are here to help in non-programming terminology 👍 |
| 01:06:26 | FromDiscord | <shadow.> can i parse a uint16 into a string with that lib lol (the sequence of bytes that make up that uint16) |
| 01:06:31 | PMunch | Oh by the way InventorMatt, you can use `.read` instead of `[0]` to access the reader part of the parser tuple |
| 01:07:00 | PMunch | Depends on what you mean "as a string" |
| 01:07:17 | PMunch | Do you want "100,200" or do you want four characters parsed as a string? |
| 01:07:24 | FromDiscord | <shadow.> four characters parsed as string |
| 01:07:29 | FromDiscord | <shadow.> for instance |
| 01:07:32 | FromDiscord | <shadow.> if x is 1000 |
| 01:07:50 | FromDiscord | <shadow.> then the string should be "bb" |
| 01:07:51 | FromDiscord | <shadow.> byte, byte |
| 01:07:58 | FromDiscord | <shadow.> since yk 2 bytes for a uint16 |
| 01:08:20 | PMunch | Huh? |
| 01:08:26 | FromDiscord | <shadow.> and yeah so if its 400, 300 it should be a string of 4 chars |
| 01:08:34 | mipri | "since you need 2 bytes for a uint16" |
| 01:08:52 | FromDiscord | <shadow.> ye sorry |
| 01:09:21 | PMunch | I'm still not sure what you want your string to be |
| 01:09:29 | FromDiscord | <shadow.> lemme get an example |
| 01:09:54 | FromDiscord | <shadow.> !eval echo cast[array[2, byte]](1000) |
| 01:09:57 | NimBot | [232, 3] |
| 01:10:03 | FromDiscord | <shadow.> the string equivalent of that basically |
| 01:10:21 | FromDiscord | <shadow.> i was wondering how that would work tho since there isnt an encoding that has yk the full range of 1 byte values afaik |
| 01:10:29 | PMunch | So chr(232) & chr(3)? |
| 01:10:32 | FromDiscord | <shadow.> ye basically |
| 01:10:58 | PMunch | Yeah, that would be a `s: yourField[2]` |
| 01:11:20 | PMunch | s for string, yourField is the name of, well, your field, and [2] is to read two bytes. |
| 01:11:28 | Zoom[m] | Eh, can you iterate over table's values with iterutils? |
| 01:11:31 | FromDiscord | <shadow.> hmm ok thanks lemme try that |
| 01:11:47 | Zoom[m] | foldl for example |
| 01:11:56 | PMunch | Zoom[m], what's wrong with `for x in myTable.values`? |
| 01:12:09 | PMunch | Oh |
| 01:12:47 | PMunch | I think you should be able to |
| 01:13:13 | FromDiscord | <shadow.> so if i have variable x which is equal to 1000, how do i get the string value? sorry |
| 01:13:14 | Zoom[m] | Nothing, it's just nice to read |
| 01:13:24 | FromDiscord | <shadow.> im a bit confused by the macro lol |
| 01:13:40 | PMunch | Oh you just have a single variable? |
| 01:13:59 | FromDiscord | <shadow.> well i have x and y sorry |
| 01:14:04 | FromDiscord | <shadow.> basically im encoding mouse x and y into a string packet lmao |
| 01:14:13 | FromDiscord | <shadow.> (edit) "basically im encoding mouse ... x" added "position" |
| 01:14:15 | PMunch | I thought you wanted to read this out of or into some binary format |
| 01:14:27 | FromDiscord | <shadow.> well i need to convert the two uint16's into a string form |
| 01:14:31 | FromDiscord | <shadow.> in binary yeah |
| 01:14:36 | FromDiscord | <shadow.> not in text form |
| 01:14:51 | FromDiscord | <shadow.> like you said before, [chr(232), chr(3)] |
| 01:14:57 | FromDiscord | <shadow.> rather than "1000" |
| 01:15:14 | PMunch | I mean you could do `cast[cstring](cast[array[4, char](x.uint32 shl 1)[1..^1])` |
| 01:15:18 | PMunch | Or something like that |
| 01:15:28 | FromDiscord | <shadow.> ahh thats what i was doing before lol |
| 01:15:32 | FromDiscord | <shadow.> except for the cstring part |
| 01:15:33 | FromDiscord | <shadow.> thanks |
| 01:16:19 | FromDiscord | <nikki> you might want to explicitly take the bytes out bc endiannness stuff |
| 01:16:25 | Zoom[m] | PMunch i get `undeclared field: 'values'` when I pass it to foldl. `1..10` in it's place works |
| 01:16:25 | FromDiscord | <shadow.> hm |
| 01:16:29 | FromDiscord | <shadow.> well the way i was going to do it was like |
| 01:16:38 | FromDiscord | <shadow.> "xxyy" |
| 01:16:42 | FromDiscord | <nikki> could look at what frosty does |
| 01:16:43 | FromDiscord | <shadow.> x being an x byte and y being a y byte |
| 01:16:58 | Zoom[m] | * PMunch i get `undeclared field: 'values'` when I pass it to foldl. `1..10` in its place works |
| 01:17:22 | FromDiscord | <nikki> yeah values is an iterator |
| 01:17:32 | FromDiscord | <nikki> can we see the whole code |
| 01:17:36 | FromDiscord | <nikki> for this foldl thing |
| 01:18:41 | FromDiscord | <nikki> why not just write a bunch of for loops 😄 |
| 01:18:43 | mipri | seems like a gap for iterutils to not be able to iterate over an iterator |
| 01:19:16 | Zoom[m] | In deed :D |
| 01:19:30 | mipri | but toSeq(xs.values).map(...) works |
| 01:20:21 | FromDiscord | <nikki> yea this is why i prefer for loops |
| 01:20:32 | FromDiscord | <nikki> no need to make intermediate seqs |
| 01:20:53 | FromDiscord | <nikki> iterators are not first class values they are kinda macros to generate loop code |
| 01:21:00 | FromDiscord | <nikki> closure iterators are more like that tho |
| 01:21:32 | PMunch | Yeah that's a bit weird |
| 01:21:38 | Zoom[m] | Yeah, it kind of defeats the purpose. Too bad they're not first class |
| 01:23:31 | Zoom[m] | Let me see what zero_functional offers |
| 01:25:05 | FromDiscord | <shadow.> how do you concatenate c strings? |
| 01:25:44 | PMunch | By turning them into strings |
| 01:25:55 | PMunch | Zoom[m], you can do this: https://play.nim-lang.org/#ix=2E4K |
| 01:25:57 | FromDiscord | <shadow.> smart |
| 01:26:24 | FromDiscord | <nikki> @shadow. i feel like you should have a buffer somewhere and just keep writing bytes to it |
| 01:26:29 | PMunch | But I feel you're doing something wrong @shadow :P |
| 01:26:37 | mipri | incidentally Kotlin made a similar choice to Nim's iterators (vs. C++/D/Rust iterators) with https://kotlinlang.org/docs/reference/inline-functions.html |
| 01:27:07 | PMunch | I think there is a PR or a thing in devel that allows you to use iterators like this |
| 01:27:09 | PMunch | IIRC |
| 01:27:19 | FromDiscord | <shadow.> i just wish the netty package supported array[byte] lol |
| 01:27:25 | FromDiscord | <shadow.> but i have to send strings |
| 01:27:32 | FromDiscord | <shadow.> i suppose i could look at the source |
| 01:27:49 | FromDiscord | <shadow.> i mean technically all i need is a way to convert an array[4, byte] to a string of 4 chars |
| 01:28:03 | Zoom[m] | Yay, zero_functional worked on a CountTable |
| 01:28:04 | FromDiscord | <nikki> yeah i just think iterator composition on data strctures is meh |
| 01:28:17 | FromDiscord | <nikki> seems fine ish on stream style things |
| 01:28:26 | FromDiscord | <nikki> nice |
| 01:28:55 | FromDiscord | <nikki> @shadow. wait it really only supports sending strings? |
| 01:29:03 | FromDiscord | <nikki> of binary data |
| 01:29:06 | mipri | well in a pinch, newString() and then copyMem(mystr[0].addr, myarray[0].addr) |
| 01:29:13 | * | abm quit (Read error: Connection reset by peer) |
| 01:29:22 | FromDiscord | <nikki> after resizing the string |
| 01:29:45 | FromDiscord | <nikki> but yeah if you setLen it to be big enough, that works |
| 01:29:50 | PMunch | Create a stringStream and use binaryparse to put your data in it |
| 01:30:11 | FromDiscord | <nikki> i think it's good to just use the string as the buffer at that point yeah |
| 01:30:26 | FromDiscord | <shadow.> alright fair enough |
| 01:30:31 | FromDiscord | <shadow.> and yeah it only supports strings from what i can tell |

| 01:34:09 | FromDiscord | <nikki> you can probs do sth similar |
| 01:34:16 | FromDiscord | <nikki> make string of cap, add stuff, send |
| 01:34:35 | PMunch | Or, you know, just use binaryparse and a string stream :P |
| 01:34:40 | PMunch | Anyways, I'm off to bed |
| 01:34:47 | FromDiscord | <shadow.> rip |

| 03:20:22 | FromDiscord | <Rika> I hope I do |
| 03:20:46 | FromDiscord | <Rika> I’d fix it if I were motivated enough, might be tomorrow, I’ll take a look then |
| 03:21:15 | disruptek | i just want a way for my bot to send privmsg through the bridge. |
| 03:22:55 | FromDiscord | <Rika> Ooh that’s a bit hard, also people can disable dm from bots in discord |
| 03:23:10 | disruptek | that's their problem. |
| 03:23:23 | FromDiscord | <Rika> Okay |
| 03:23:40 | FromDiscord | <Rika> I’ll look into it tomorrow, not like I have anything to do during this damn quarantine |

| 05:07:25 | FromDiscord | <Daniel> i got the error again https://media.discordapp.net/attachments/371759389889003532/777036942473822248/unknown.png |
| 05:07:32 | FromDiscord | <Daniel> but i found it accidentaly |
| 05:07:39 | FromDiscord | <Daniel> it was this space before hello |
| 05:07:49 | FromDiscord | <Daniel> i thought space would be ignored inside |
| 05:07:59 | disruptek | nah. it's a string. |
| 05:08:07 | FromDiscord | <VideoCarp> never knew the `for` can be done like python, but it had the same problem, doing all of them. |
| 05:08:34 | FromDiscord | <Daniel> yea its a string, but isnt only stuff in quotes analysed? |
| 05:08:37 | disruptek | echo your unit. |
| 05:08:52 | disruptek | daniel: it's in quotes. it's triple-quoted, in fact. |
| 05:09:20 | FromDiscord | <Daniel> is it because of triple quotes then? |
| 05:10:07 | FromDiscord | <nikki> it's because the json output you're checking against doesn't have the space |
| 05:10:30 | FromDiscord | <VideoCarp> when using `h`, it results in `hhhhhhhhhhhhh` with newlines separating each character.↵so it’s getting the right input. |
| 05:10:32 | disruptek | triple-quotes are syntax for strings. |
| 05:11:33 | FromDiscord | <Daniel> righto, thank you, going to bed, my brain is soup, gn |
| 05:11:40 | FromDiscord | <VideoCarp> i think they’re multiline strings |

| 14:25:27 | supakeen | You can take a look at some of the codebases around such as npeg, etc but I don't know if there's really any 'standard of formatting' :) |
| 14:25:36 | FromDiscord | <haxscramper> Can read stdlib implementation. But there is no difference really between large and small-scale format |
| 14:26:15 | disruptek | everything i've ever written is perfect. |
| 14:26:18 | FromDiscord | <haxscramper> Most code I've seen formatted like stdlib (`camelCase`, 2 spaces indentation and that's about it) |

| 14:30:44 | Zevv | yeah npeg is the new standard |

| 14:34:36 | disruptek | 1) `for t in items tees:` or 2) `for t in tees.items:` or 3) `for t in tees:`... vote. |

| 14:41:20 | FromDiscord | <Rika> id do 3 |
| 14:44:26 | disruptek | i've been experimenting with 1 but i think i'm going back to 2. |
| 14:45:59 | FromDiscord | <Rika> 1 looks really weird to me |
| 14:46:04 | FromDiscord | <Rika> i do 2 sometimes |
| 14:46:55 | disruptek | the goal is to remove implicit items/pairs, and being more explicit is, to me, a win. |
| 14:47:19 | disruptek | ie. nim-2 probably won't do implicit items/pairs. |
| 15:01:03 | FromDiscord | <dom96> `for t in items(tees)` is the winner |
| 15:01:38 | disruptek | the problem with it is that the piece of info you want to convey earliest, that is most important for comprehension, is `tees`. |
| 15:02:22 | disruptek | "in items" becomes noise. |
| 15:03:32 | disruptek | .items can be thought of as conversion, which maybe makes it easier to accept. |
| 15:06:35 | Zevv | i always 3. I like terse. Its not like it's ambigious |
| 15:07:40 | disruptek | i didn't get that talk. |
| 15:08:21 | disruptek | could be that i just take the theorems for granted, though. |
| 15:09:42 | disruptek | but i definitely sympathize with the introduction of expression as a can-o-worms that i don't always want to unpack; timmy tends to aggravate these things. |
| 15:13:13 | disruptek | Zevv: this is why the `return in expr` is so disturbing to me. |

| 15:14:09 | supakeen | i like doms |
| 15:15:34 | FromDiscord | <haxscramper> `3` might suffer from some generic issues - e.g. you can't easily (AFAIK) mixin implicit `items` |
| 15:17:46 | disruptek | not sure what you mean. |
| 15:18:16 | disruptek | the omission of the iterator is, afaik, sugar. |
| 15:22:48 | FromDiscord | <haxscramper> sent a code paste, see https://paste.rs/1MV |
| 15:23:01 | FromDiscord | <haxscramper> If I add `items` to `difference` implementation it works |
| 15:24:16 | FromDiscord | <haxscramper> Something like that. But this has issue already AFAIC, I just don't remember which one |
| 15:24:35 | disruptek | huh. i don't use mixin. |
| 15:24:47 | disruptek | can't remember if it's because of this, though. |
| 15:25:14 | FromDiscord | <haxscramper> It doesn't change anything here actually - unless I edit `std/sets.difference` nothing works |
| 15:25:30 | FromDiscord | <haxscramper> Need to make smaller example actually |
| 15:25:52 | disruptek | i'm not sure it's wrong, honestly. |

| 15:29:26 | * | natrys joined #nim |
| 15:30:32 | disruptek | well, if you make it explicit, the sugar doesn't run. |
| 15:31:21 | disruptek | probably the sugar isn't working correctly and this is another reason not to use it. |
| 15:33:09 | FromDiscord | <haxscramper> `for val in u: discard` should be identical to `for val in items(u): discard`, right? But it seems that it is not. Just another argument against `3`. And `.items` call can also suffer from some symbol resolution issues, so `items()` it the safest one. For generic code especially |
| 15:47:32 | disruptek | you mean ufcs issues with templates? |
| 15:48:45 | disruptek | i've stopped using () for calls with a single argument unless the syntax is ambiguous. |
| 16:09:52 | FromDiscord | <shadow.> is there any way to copyMem into a tuple? for instance copying into a tuple(uint16, uint16) from an array[4, uint8] |
| 16:11:30 | * | evilkhaoskat quit () |
| 16:13:35 | FromDiscord | <lqdev> yeah |
| 16:13:42 | FromDiscord | <Idefau> you could declare a type as a tuple of some length |

| 20:28:52 | haxscramper | No, this is construction of the tree, just using the same DSL |
| 20:29:08 | haxscramper | The same parser for DSL. Like pattern matching but in reverse |
| 20:30:00 | planetis[m] | its huge you put a lot of effort on it |
| 20:30:53 | planetis[m] | i just copied karaxdsl, hope it's useful to other ppl |
| 20:32:01 | FromGitter | <ynfle> @Zoom, Here is an implementation using generics https://play.nim-lang.org/#ix=2Eb2 |
| 20:32:46 | * | habamax quit (Ping timeout: 244 seconds) |
| 20:33:42 | Zoom[m] | ynfle, thanks. there's a place in the docs and/or nimbyexample for this somewhere! |
| 20:33:54 | * | Axiomatic left #nim ("Leaving") |
| 20:34:13 | haxscramper | planetis[m]: Yeah, I thought that too. I'm not familliar with karax though, so maybe there is some things besides splicing logic and ast generation? `makeTree` is not a full 'reverse' - things like `all` etc. are not supported yet. With these additions there would probably be an overlap on feaures |
| 20:34:42 | FromGitter | <ynfle> Are you asking if there is place in the docs for this application of generics specifically? Not that I'm aware of |
| 20:34:59 | FromGitter | <ynfle> ~generics |
| 20:34:59 | disbot | no footnotes for `generics`. 🙁 |
| 20:35:22 | FromGitter | <ynfle> https://nim-lang.org/docs/manual.html#Generics |
| 20:35:43 | Zoom[m] | This was not a question :) I meant the docs should mention this possibility right after saying you can't have multidim openarrays. |
| 20:42:42 | planetis[m] | haxscramper: no thats exactly what it does. Its quite good |
| 20:43:19 | planetis[m] | Im not familiar with maketree but will check it |
| 20:45:24 | planetis[m] | I must say im quite satisfied with how it turned. I mean repurposing a web dsl into macros and its just working |
| 20:46:49 | planetis[m] | I want to show @Araq after all he wrote all the logic |
| 20:47:52 | haxscramper | https://raw.githubusercontent.com/haxscramper/fusion/matching/src/fusion/matching.rst - for `makeTree` (github can't deal with `.. code:: nim`, so link is to raw `.rst`). |
| 20:49:51 | planetis[m] | haxscramper: are you aware of https://github.com/krux02/ast-pattern-matching ? |
| 20:49:55 | haxscramper | Yes |
| 20:50:20 | haxscramper | Yes, I'm aware of absolutely all pattern matching implementations for nim |
| 20:51:08 | haxscramper | But `ast-pattern-matching` is not generic (e.g only `NimNode`) |
| 20:52:59 | haxscramper | Pattern /matching/ dsl alreay supports loops in form of `all`, `any`, `none`, and `until` as well as custom predicates. Just need to come up with semantics for `makeTree` that would exactly mirror `match` part. |
| 20:56:44 | planetis[m] | All these sound so complicated to me, i have to admit |
| 20:59:02 | haxscramper | You can match nim node using `matches:⮒ StmtList[all @statements]` - and it will inject `statements` variable. So it is logical (well, at least to me) to think that `makeTree:⮒ StmtList[all @statements]` would create `StmtList` node and add all elements from `statements`. |
| 20:59:39 | planetis[m] | yes that makes sense |
| 21:00:47 | FromDiscord | <notchris> Hello friends |
| 21:01:02 | notchris | o/ |
| 21:02:16 | haxscramper | But the problem is - I also have `StmtList[until @elements is Ident(strVal: "stop")]` that would capture elements until first `stop` identifier in statment list. But for `makeTree` it might be a bit pointless. Though kind of logical to expect, so I would probably stick to it too. |
| 21:04:18 | planetis[m] | Now that you explain it, it all makes sense, its just im not used to program declaretively |
| 21:07:17 | haxscramper | Good point actually. I kind of forgot about this, so should probably include more examples of how things like `all` etc. map into for loops/ifs and so on. |

| 21:52:42 | FromDiscord | <notchris> if i have a C lib that is just a UI bundled into a single header file |
| 21:52:50 | * | narimiran quit (Ping timeout: 264 seconds) |
| 21:53:01 | FromDiscord | <notchris> whats the easiest way to interact with it without using c2nim etc |
| 21:53:45 | FromDiscord | <nikki> `proc foo(blah: cstring, bleh: int): int {.importc, header: "\"theheader.h\"".}` |
| 21:53:53 | FromDiscord | <nikki> should let you call eg. foo from the lib |
| 21:54:10 | FromDiscord | <notchris> so i need to find where its rendering to a surface and starting a window first right |
| 21:54:59 | FromDiscord | <nikki> depends on what the ui lib is saying i think. if it expects a window handle, or if it creates its own window etc. 🤔 |
| 21:55:39 | FromDiscord | <notchris> hmmm |

| 23:02:57 | FromDiscord | <ElegantBeef> it quite possibly is under `std/enumerate` |

| 23:04:54 | FromDiscord | <j-james> What are some good GUI libraries for Nim? |

| 23:06:41 | FromDiscord | <ElegantBeef> Fidget, Nimx, WebGUI |
| 23:06:54 | * | Axiomatic left #nim ("Leaving") |
| 23:07:26 | FromDiscord | <ElegantBeef> What type of GUI do you want though, "native" or native? |
| 23:09:29 | FromDiscord | <j-james> I suppose native |
| 23:09:55 | FromDiscord | <j-james> This is mostly for learning, not for a full-fledged project |
| 23:10:08 | FromDiscord | <ElegantBeef> Well then you've got Nigui if you want cross platform native |
| 23:10:39 | FromDiscord | <ElegantBeef> It's also "native" since on linux/mac it uses gtj |
| 23:10:42 | FromDiscord | <ElegantBeef> (edit) "gtj" => "gtk" |
| 23:10:56 | FromDiscord | <ElegantBeef> But on windows it does use windows GUI, so close enough |
| 23:16:07 | FromDiscord | <j-james> Thanks, I'll give that a whirl |
| 23:16:24 | * | solitudesf quit (Ping timeout: 256 seconds) |
| 23:28:56 | FromDiscord | <ElegantBeef> So i'm curious is the `_` in `for _ in 0..10` supposed to be accessible, I know underscore is the unused indicator and if you do it in a `let _ = 100` then try to access it the identfier doesnt exist, shouldnt it be the case for `for` aswell? |
| 23:38:40 | FromDiscord | <nikki> i think it's not supposed to be accessible |
| 23:38:52 | FromDiscord | <nikki> like you can do `for _, _ in ...` -- and if it was accessible that would cause an ambiguity |
| 23:39:13 | * | lritter quit (Remote host closed the connection) |
| 23:39:35 | FromDiscord | <nikki> one "somewhat analogous" place where you can't actually do multiple `_` is in parameter lists -- like you can't do `proc(_, _: int)` to take two `int`s that you ignore iirc |
| 23:46:11 | FromDiscord | <krabbypatty> huh |
| 23:46:20 | FromDiscord | <krabbypatty> nim accepts both `case x` and `case x:` |
| 23:47:04 | FromDiscord | <krabbypatty> first one should be probably emit a syntax error? |
| 23:47:09 | FromDiscord | <krabbypatty> (edit) removed "be" |
| 23:51:25 | FromDiscord | <ElegantBeef> @nikki yea that was my intuition as well but it's for a normal `for _ in iterator` |
| 23:51:33 | FromDiscord | <ElegantBeef> So i guess time to make an issue 😄 |
| 23:52:46 | FromDiscord | <nikki> @ElegantBeef yea it's accessible indeed |
| 23:52:54 | FromDiscord | <nikki> 🤔 |
| 23:53:20 | FromDiscord | <ElegantBeef> I used the playground and it compiles in every version |
| 23:53:23 | FromDiscord | <ElegantBeef> So it's weird indeed |
