| 00:00:04 | prussianboy | now I can truyl feel like MrRobot |
| 00:00:17 | FromDiscord | <carpal> oh rip |
| 00:00:28 | FromDiscord | <carpal> why nobody continued to support it? |
| 00:00:40 | FromDiscord | <Zachary Carter> because no one wants to maintain a kernel or write an OS with Nim atm? |
| 00:00:46 | leorize | no one cared enough |
| 00:00:49 | FromDiscord | <Zachary Carter> I think it was more of a demonstration project |
| 00:00:59 | prussianboy | you think a OS would be faster if it was written in nim? |
| 00:01:02 | leorize | yea, just to demo that you can develop a kernel in nim |
| 00:01:16 | FromDiscord | <Clyybber> there are a few forks of nimkernel that were developed further AFAIR |
| 00:01:16 | leorize | prussianboy: no. safer then maybe. |
| 00:01:25 | FromDiscord | <Zachary Carter> I think operating systems are mostly written in C and assembly language |
| 00:01:32 | FromDiscord | <Zachary Carter> I don't think Nim would make them any faster |
| 00:02:04 | prussianboy | I would be down to develop a new OS that gives back the power to the people like Urbit, if you have heard of that |
| 00:02:26 | asdflkj | Urbit is interesting |
| 00:02:26 | FromDiscord | <Zachary Carter> @Clyybber yeah I think so - although I think if any of them got it compiling again they would have been merged |
| 00:02:59 | FromDiscord | <Zachary Carter> I think developing a new OS is beyond the ambitions of most Nim community members |
| 00:03:32 | prussianboy | im generally looking for some cool project to do, do you have some ideas? |
| 00:03:53 | prussianboy | someone recommended a package manager, but i think nimble is decent enough |
| 00:04:01 | leorize | it's not |
| 00:04:13 | prussianboy | would that be a worthwile endeavour? |
| 00:04:20 | FromDiscord | <Clyybber> @Zachary Carter https://github.com/alehander92/lodka , https://github.com/tyler569/nimk |
| 00:04:26 | leorize | your program compile today then tomorrow it either stop compiling or send nimble into a spiral of doom |
| 00:04:50 | FromDiscord | <Clyybber> both updated this year |
| 00:04:55 | FromDiscord | <Clyybber> eh, last year |
| 00:05:00 | FromDiscord | <Zachary Carter> yeah I remember folks starting to work on them |
| 00:05:09 | FromDiscord | <Zachary Carter> I guess if they compile then they should PR to dom96's repo |
| 00:05:24 | FromDiscord | <Zachary Carter> but I'm sure there's some reason they haven't |
| 00:05:33 | FromDiscord | <Clyybber> because they diverged? |
| 00:05:38 | FromDiscord | <Zachary Carter> well probably |
| 00:05:40 | FromDiscord | <Clyybber> or because its a personal project I presume |
| 00:05:43 | prussianboy | leorize: perhaps I will look into it |
| 00:05:53 | FromDiscord | <Zachary Carter> I think the goal of both of them was to get dom96's project working |
| 00:06:03 | FromDiscord | <Zachary Carter> at least in the case of alehander92's repo |
| 00:06:10 | leorize | prussianboy: you will need to study a lot of theory behind package management :P |
| 00:06:18 | leorize | and what the community has been talking about |
| 00:06:24 | FromDiscord | <Zachary Carter> but maybe he went in a different direction, I don't know |
| 00:06:25 | prussianboy | perhaps not a good start then :D |
| 00:06:41 | FromDiscord | <Zachary Carter> I mean how experienced of a programmer are you |
| 00:06:47 | FromDiscord | <Zachary Carter> and what kind of applications do you like to write? |
| 00:07:21 | FromDiscord | <Zachary Carter> Nim can be applied to a lot of different problem domains |
| 00:07:39 | prussianboy | im a cs major in 3rd year |
| 00:07:43 | FromDiscord | <Zachary Carter> system development, application development, web development, embedded develeopment, etc... |
| 00:07:51 | prussianboy | know Java, Python, ML, C |
| 00:07:57 | prussianboy | never done a big project alone tho |
| 00:08:05 | prussianboy | i just wanna create something useful |
| 00:08:05 | asdflkj | I’d like if someone patched nimble to calculate a package’s size (ideally including deps) and tell you before asking if you want to download |
| 00:08:37 | prussianboy | i guess I would do either sys dev or app deb |
| 00:08:39 | prussianboy | *dev |
| 00:08:49 | FromDiscord | <Zachary Carter> if you want to contribute to the language, maybe ask another core dev or look at the issue tracker and find some issues that interest you |
| 00:08:58 | FromDiscord | <Zachary Carter> when 4raq is around you can ask him what might need working on |
| 00:09:06 | FromDiscord | <carpal> I think no, it compiles to C, so faster than C code cannot run... |
| 00:09:11 | FromDiscord | <Zachary Carter> if you want to build something in user land, just pick your fancy |
| 00:09:13 | leorize | asdflkj: pretty much impossible, sadly |
| 00:09:24 | prussianboy | hmm |
| 00:09:26 | FromDiscord | <carpal> maybe compiling C code with a g++ compiler |
| 00:09:39 | FromDiscord | <carpal> could it works? |
| 00:09:45 | leorize | you can write C that compiles to faster C |
| 00:09:47 | leorize | :P |
| 00:09:53 | asdflkj | leorize: it works for apt, and most packages seem to come from github, which has an api that tells the size of a repo |
| 00:10:15 | leorize | asdflkj: it's due to nimble design |
| 00:10:18 | prussianboy | im thinking of some commandline application to start wit |
| 00:10:32 | asdflkj | I’m thinking of making a simple terminal file manager based on fff, and if it works well, adapting it to be like lf |
| 00:10:44 | asdflkj | / ranger |
| 00:11:26 | asdflkj | it would be as fast as lf, as readable code as ranger, and maybe the smallest binary size |
| 00:11:55 | leorize | asdflkj: unlike your typical package manager with a static dependency file, `.nimble` is a nimscript file that has to be executed to retrieve the list of dependency, so you can't reasonably calculate the dependencies without downloading them |
| 00:12:16 | prussianboy | asdflkj: I would use that |
| 00:12:36 | asdflkj | prussianboy: awesome |
| 00:13:00 | asdflkj | wish me luck and the ability to stop wasting time here and finish the nim tut :) |
| 00:26:10 | FromDiscord | <K-> how do i switch discord channels in irc? |
| 00:26:35 | leorize | you join more channels |
| 00:26:53 | FromDiscord | <K-> as in #nim-nimble? |
| 00:27:38 | asdflkj | as in /join #nim-nologs |
| 00:27:44 | leorize | yea but not that one |
| 00:28:15 | FromDiscord | <K-> lmao why not |
| 00:28:17 | leorize | since Yardanico didn't bridge that one to irc iirc |
| 00:28:40 | FromDiscord | <K-> yeah but lets say another like science |
| 00:29:06 | leorize | it was originally gonna be bridged to #nimble but some other project took it |
| 00:29:16 | leorize | #nim-science is the place to go |
| 00:30:55 | FromDiscord | <K-> how can I switch channels in weechat |
| 00:31:41 | leorize | you should see the buflist, right? |
| 00:31:47 | leorize | alt + array |
| 00:31:49 | leorize | alt + arrow* |
| 00:32:03 | FromDiscord | <K-> ahh |
| 00:32:04 | FromDiscord | <K-> thanks |
| 00:44:54 | FromGitter | <gogolxdong> When should -d:useMalloc be used? |
| 00:45:00 | disruptek | when using valgrind. |
| 00:49:03 | FromGitter | <gogolxdong> Is it expected to be used with arc or orc, or only for debug |
| 00:51:46 | ForumUpdaterBot | New thread by RainbowAsteroids: Why aren't the built-in math procs (`+`, `-`, `*`, ...) procvars?, see https://forum.nim-lang.org/t/7416 |
| 00:51:49 | FromDiscord | <Yardanico> only for debugging |
| 00:51:57 | FromDiscord | <Yardanico> it's slower and not really optimized IIRC |
| 00:52:22 | FromDiscord | <Yardanico> you only use it to debug memory leaks or maybe for some platform (os) that doesn't have the nim memory manager ported |
| 00:52:27 | FromDiscord | <Yardanico> or embedded sometimes |
| 00:52:35 | FromDiscord | <Yardanico> I've used -d:useMalloc in the past to compile nim for KolibriOS |

| 07:44:54 | saem | oh this is fun... so nimsuggest is up, it's run sem on the project. Ask for a suggestion at a position that is for an expression inside a macro that will output the actual code. Everything works macro's AST is output (with some errors), but suggest can deal. Ask the same thing again: a bunch of broken AST has nfSem set, doesn't get sem again, macros don't eval again, more things are broken, now suggestion fail. |
| 07:49:20 | saem | Maybe I'll have a better idea in the morning, but I think suggest should track a node which marks the boundary of what it had to paper over and then after everything is output and before processing the next command strip the nfSem flag. |
| 07:49:20 | saem | This feels hacky and it seems like the real fix should be something about managing various lifetimes more precisely. 🤔 |

| 10:00:27 | FromDiscord | <mratsim> in that case ptr UncheckedArray[ptr float64] |
| 10:00:33 | FromDiscord | <mratsim> ah |
| 10:00:44 | FromDiscord | <ElegantBeef> @hamidb80 use `importc:"varName"` to import it to nim |
| 10:00:46 | FromDiscord | <mratsim> it's just a ptr UncheckedArray[float64] |
| 10:01:43 | FromDiscord | <JSONBash> @mratsim thanks I will give that a try! |
| 10:06:23 | FromDiscord | <JSONBash> and if I have `data: UncheckedArray[float64]` then to pass that to a the proc would be `exampleProc(ptr data)`? |

| 11:11:21 | FromDiscord | <Clyybber> the array will be on the stack in your example |
| 11:11:34 | FromDiscord | <Clyybber> if you change it to Stack = ref object then it will be on the heap |
| 11:11:43 | FromDiscord | <Clyybber> you can also do ref array[1000, int] |
| 11:11:49 | FromDiscord | <Clyybber> or ptr array[1000, int] |
| 11:13:41 | FromDiscord | <carpal> https://media.discordapp.net/attachments/371759389889003532/802496267833442304/unknown.png |
| 11:14:15 | FromDiscord | <carpal> I don't know how to make it works https://media.discordapp.net/attachments/371759389889003532/802496411874361394/unknown.png |
| 11:14:30 | FromDiscord | <mratsim> yes it can, it's only 8kB |
| 11:15:14 | ForumUpdaterBot | New thread by Drkameleon: Morgenstern-ish documentation, see https://forum.nim-lang.org/t/7418 |
| 11:15:28 | FromDiscord | <mratsim> but the issue is that with the default GC, your code will be slow. The default GC scans the stack for root and it's a linear scan AFAIK. |
| 11:16:32 | FromDiscord | <mratsim> ARC doesn't scan for root so you won't get the penalty. Or gc:boehm. |
| 11:19:06 | FromDiscord | <carpal> so can anyone help me |
| 11:20:42 | FromDiscord | <Rika> Have you tried compiling it carpal |
| 11:20:48 | FromDiscord | <Rika> What was the error |
| 11:21:12 | FromDiscord | <Rika> Oh the template is wrong |
| 11:21:12 | * | radgeRayden joined #nim |
| 11:21:45 | * | abm joined #nim |
| 11:21:55 | FromDiscord | <Rika> You can’t easily modify a procedure in a template like that, you’d need a macro if you wanted to change the parameters |
| 11:27:28 | FromDiscord | <Clyybber> extend Stack, selfMethod:↵ self.embed |
| 11:29:08 | FromDiscord | <carpal> I'm I don't like that syntax @Clyybber |
| 11:29:24 | FromDiscord | <Clyybber> then you'll want a macro |
| 11:29:41 | FromDiscord | <carpal> I prefer to declare all procedures in the extend block |
| 11:30:12 | FromDiscord | <carpal> yes, I've already seen a thing like this I'm trying to do in godot-nim |
| 11:30:48 | FromDiscord | <carpal> https://media.discordapp.net/attachments/371759389889003532/802500577602043924/unknown.png |
| 11:31:09 | FromDiscord | <carpal> a similar thing |
| 11:31:13 | FromDiscord | <Clyybber> yep |
| 11:32:02 | FromDiscord | <carpal> ok, so what I need to do? |

| 11:42:29 | FromDiscord | <carpal> ah ok |
| 11:42:31 | FromDiscord | <Clyybber> yeah |

| 12:06:37 | FromDiscord | <carpal> ah ok |
| 12:07:04 | FromDiscord | <carpal> would be allocated on the stack? https://media.discordapp.net/attachments/371759389889003532/802509702269370388/unknown.png |
| 12:11:08 | * | hoijui quit (Quit: Leaving) |
| 12:11:20 | FromDiscord | <haxscramper> No, this is a `ref object`, it will be on heap |
| 12:12:57 | FromDiscord | <haxscramper> And generally you don't need to be concerned with stack/heap allocation, and only think about value/ref semantics as it directly affects how code is going to work |
| 12:15:14 | * | superbia joined #nim |
| 12:15:47 | FromDiscord | <Rika> i think hes concerned with performance? |
| 12:32:07 | FromDiscord | <carpal> yea I know, I changed it a few minutes leter |
| 12:32:51 | FromDiscord | <carpal> but `pointer` is a true pointer of like void it can be used as any type? |
| 12:32:58 | FromDiscord | <carpal> (edit) "void" => "`void`" |
| 12:33:58 | FromDiscord | <lqdev> yes |
| 12:34:09 | FromDiscord | <carpal> how can I get access to `maxSize` field? https://media.discordapp.net/attachments/371759389889003532/802516517513461800/unknown.png |
| 12:34:15 | FromDiscord | <carpal> (edit) "field?" => "field from a proc?" |
| 12:34:31 | FromDiscord | <lqdev> you should be able to just use it i think |
| 12:34:46 | FromDiscord | <lqdev> and if you can't, you'll need to add it as a generic param explicitly |
| 12:34:51 | FromDiscord | <carpal> https://media.discordapp.net/attachments/371759389889003532/802516695951867944/unknown.png |
| 12:34:56 | FromDiscord | <Rika> That’s a generic parameter isn’t it |
| 12:34:57 | FromDiscord | <lqdev> also you want this to be a `static Natural` |
| 12:35:26 | FromDiscord | <lqdev> otherwise it'll match any types that are compatible with Natural, and not actual Naturaks |
| 12:35:29 | FromDiscord | <lqdev> (edit) "Naturaks" => "Naturals" |
| 12:35:36 | FromDiscord | <carpal> ah yea |
| 12:35:41 | FromDiscord | <carpal> with static it works |
| 12:47:56 | * | Vladar quit (Remote host closed the connection) |
| 12:52:02 | * | tane quit (Quit: Leaving) |
| 13:13:01 | FromDiscord | <mratsim> Natural are a pain to work with as static |
| 13:13:14 | FromDiscord | <mratsim> I suggest you use static int or you will have type mismatch issues |
| 13:13:26 | ForumUpdaterBot | New thread by HJarausch: Nim compiler follows symbolic links too eagerly, see https://forum.nim-lang.org/t/7419 |
| 13:13:48 | FromDiscord | <carpal> aoky |
| 13:13:49 | FromDiscord | <carpal> (edit) "aoky" => "okay" |
| 13:13:53 | FromDiscord | <carpal> I'll try |
| 13:18:20 | FromDiscord | <lqdev> yeah in general any number type other than static int doesn't work well |
| 13:18:41 | FromDiscord | <lqdev> i had a really weird type mismatch issue that was disguised under a weird error |
| 13:18:53 | FromDiscord | <lqdev> and the problem was that i was passing an int32 to a static int generic param |
| 13:19:56 | FromDiscord | <carpal> yes infact now it works |
| 13:20:28 | FromDiscord | <carpal> is there a way to print a pointer value/instance name (like in c#)? |
| 13:20:53 | FromDiscord | <Rika> pointer value as in the address? |
| 13:20:57 | FromDiscord | <carpal> without knowing the type pointer points to |
| 13:20:59 | FromDiscord | <Rika> instance name as in the type name? |
| 13:21:10 | FromDiscord | <carpal> ye |
| 13:21:15 | FromDiscord | <Rika> yes to both? |
| 13:22:02 | FromDiscord | <carpal> as IN the adress |
| 13:22:05 | FromDiscord | <carpal> (edit) "adress" => "address" |
| 13:22:12 | FromDiscord | <carpal> not the pointer value |
| 13:22:12 | FromDiscord | <lqdev> repr |
| 13:22:39 | FromDiscord | <lqdev> or $cast[int](yourptr) |
| 13:22:51 | FromDiscord | <lqdev> if you feel repr is too noisy |
| 13:24:41 | FromDiscord | <carpal> yes but Idk the pointer type |
| 13:24:59 | FromDiscord | <carpal> I can't convert a pointer into a int while the pointer points to a string pointer lol |
| 13:25:18 | FromDiscord | <lqdev> a pointer is the same size as an int |
| 13:25:26 | FromDiscord | <lqdev> so that conversion is safe |
| 13:25:31 | FromDiscord | <carpal> long in x64 |
| 13:25:39 | FromDiscord | <lqdev> no |
| 13:25:43 | FromDiscord | <lqdev> we're not talking C terms here |
| 13:25:54 | FromDiscord | <lqdev> in nim sizeof(int) is always == sizeof(pointer) |
| 13:26:03 | FromDiscord | <carpal> ah ok |
| 13:26:21 | FromDiscord | <lqdev> `cast` is a bit cast |
| 13:26:36 | FromDiscord | <lqdev> so you're essentially interpreting the pointer itself as an int |
| 13:27:02 | FromDiscord | <lqdev> not the value under the pointer |
| 13:27:29 | FromDiscord | <lqdev> if you wanted to intepret the value under the ptr as an int, you'd do `cast[int](yourptr[])` to dereference it before casting |
| 13:28:05 | FromDiscord | <lqdev> for debugging yourptr.repr is good enough though |
| 13:32:28 | FromDiscord | <carpal> ... I should print elem, taken from an array of pointer https://media.discordapp.net/attachments/371759389889003532/802531193618432010/unknown.png |
| 13:32:35 | FromDiscord | <carpal> (edit) "pointer" => "`pointer`" |
| 13:33:22 | FromDiscord | <Rika> is elem a `pointer`? do you know its type |
| 13:33:26 | FromDiscord | <Rika> under the pointer i mena |
| 13:33:38 | FromDiscord | <lqdev> elem.repr |
| 13:34:27 | FromDiscord | <Rika> well thats if you only want the address |
| 13:34:31 | FromDiscord | <carpal> is an array element of nim type `pointer` |
| 13:34:43 | FromDiscord | <carpal> assigned with addr(varr...) |
| 13:35:17 | FromDiscord | <carpal> no, unknown type |
| 13:35:19 | FromDiscord | <Rika> so what do you want to print from elem? |
| 13:35:29 | FromDiscord | <Rika> address? |
| 13:35:30 | FromDiscord | <carpal> it could be a string, int, float, instance of any type |
| 13:35:36 | FromDiscord | <carpal> value |
| 13:35:41 | FromDiscord | <carpal> but without type... |
| 13:35:46 | FromDiscord | <Rika> thats impossible unless you know the type |
| 13:35:53 | FromDiscord | <carpal> in c# it is possible |
| 13:35:59 | FromDiscord | <carpal> with .net object |
| 13:36:12 | FromDiscord | <Rika> because that's probably something else and you are misunderstanding what it does |
| 13:36:33 | FromDiscord | <carpal> pointer is the same as void? |
| 13:36:49 | FromDiscord | <Rika> in C, not C# |
| 13:36:51 | FromDiscord | <Rika> yes |
| 13:38:06 | FromDiscord | <carpal> ok knowning the type= |
| 13:38:07 | FromDiscord | <carpal> (edit) "type=" => "type?" |
| 13:38:21 | FromDiscord | <carpal> https://media.discordapp.net/attachments/371759389889003532/802532672932020244/unknown.png |
| 13:38:27 | FromDiscord | <Rika> knowing the type, `cast[ptr Type](elem)[]` |
| 13:38:31 | FromDiscord | <carpal> this prints a wrong number |
| 13:38:33 | FromDiscord | <carpal> ah ok |
| 13:38:57 | FromDiscord | <Rika> you have to cast the pointer into another pointer, that casts the pointer into an integer |
| 13:39:02 | FromDiscord | <carpal> ok it works |
| 13:39:08 | FromDiscord | <carpal> but why []? |
| 13:39:12 | FromDiscord | <Rika> dereference |
| 13:39:20 | FromDiscord | <Rika> same as c's `` on a value |
| 13:39:27 | FromDiscord | <Rika> variable, rather |
| 13:41:21 | FromDiscord | <carpal> and how does `any` work? |
| 13:43:34 | FromDiscord | <lqdev> it's an implicit generic |
| 13:43:52 | FromDiscord | <lqdev> and its use is discouraged in favor of auto |
| 13:44:30 | FromDiscord | <lqdev> your problem is that ptrs do not carry type information at runtime |
| 13:44:59 | FromDiscord | <lqdev> your solution would be to create a variant object |
| 13:45:13 | FromDiscord | <carpal> infact lol https://media.discordapp.net/attachments/371759389889003532/802534403250847774/unknown.png |
| 13:45:35 | FromDiscord | <lqdev> `case code: ObjectCode` |
| 13:45:42 | FromDiscord | <lqdev> `of ocInt: intVal: int` |
| 13:45:44 | FromDiscord | <lqdev> etc |
| 13:46:09 | FromDiscord | <lqdev> if you don't wanna have a value, like in case of `ocNull` you can use either discard or nil |
| 13:46:16 | FromDiscord | <lqdev> like `of ocNull: discard` |

| 14:32:48 | FromDiscord | <Deorder> Ah found out how already |
| 14:33:16 | FromDiscord | <Deorder> Just change nim.cfg |
| 14:33:35 | FromDiscord | <haxscramper> `--cc:vcc` for `nimble build` or `nim c` would be sufficient if you want to just run it manually |
| 14:33:40 | FromDiscord | <Deorder> (edit) "Just change nim.cfg ... " added "and modify cc = gcc to cc = vcc" |
| 14:33:55 | FromDiscord | <haxscramper> Or yes, put in config form permanent configuration |
| 14:33:59 | FromDiscord | <haxscramper> (edit) "form" => "for" |
| 14:34:41 | FromDiscord | <Deorder> I actually do that when using Nim under Linux all the time to use clang, but somehow while using Nim under Windows I entirely forgot about it. |

| 14:54:13 | FromDiscord | <lqdev> `man` doesn't show me any info on `getsize` |
| 14:54:21 | FromDiscord | <mratsim> isn't that something allocator specific? |

| 15:02:10 | FromDiscord | <carpal> clang? |
| 15:02:19 | FromDiscord | <lqdev> gcc |
| 15:02:31 | FromDiscord | <carpal> I used it a few week ago with clang assembler |
| 15:02:50 | FromDiscord | <carpal> you pass to it a pointer and it returns you the block size |
| 15:02:54 | FromDiscord | <carpal> bytheway I fixed |
| 15:02:57 | FromDiscord | <carpal> https://media.discordapp.net/attachments/371759389889003532/802553966318714880/unknown.png |
| 15:03:00 | FromDiscord | <carpal> it works!! |
| 15:03:08 | FromDiscord | <Rika> nice |
| 15:03:58 | FromDiscord | <carpal> .... Idk if it is ok, but it works https://media.discordapp.net/attachments/371759389889003532/802554220108447825/unknown.png |
| 15:04:13 | FromDiscord | <carpal> so if it isn't optimized it doesn't matter |
| 15:05:04 | FromDiscord | <Rika> looks fine to me |
| 15:14:49 | FromDiscord | <mratsim> A lot of Nim mentions in the article: https://medium.com/supranational/introducing-blst-2b6a988d68ee |
| 15:17:19 | FromDiscord | <carpal> for make more compact the code, I could make Object generic and remove case of |
| 15:17:41 | FromDiscord | <lqdev> you couldn't actually |
| 15:17:49 | FromDiscord | <carpal> but only if there is a way to store |
| 15:18:17 | FromDiscord | <carpal> a generical ref to a generic.... ok I'll explain me better |
| 15:18:24 | FromDiscord | <lqdev> the reason why you can't make it generic is because then `Object` is not a concrete type. its size would be determined by what it stores |
| 15:18:48 | FromDiscord | <lqdev> while a variant object's size is the discriminator + the largest of its branches |
| 15:20:09 | FromDiscord | <carpal> sent a code paste, see https://play.nim-lang.org/#ix=2N36 |
| 15:20:21 | FromDiscord | <carpal> is it possible to do? |
| 15:23:29 | FromDiscord | <Rika> no |
| 15:24:44 | FromDiscord | <carpal> rippoz |
| 15:27:22 | FromDiscord | <lqdev> the variant object is the right way to do it |
| 15:28:09 | FromDiscord | <carpal> interesting, what are you talking about? |

| 16:44:04 | disruptek | the blockfi folks asked me what i dislike most about nim. |
| 16:44:56 | disruptek | i told them about empty room syndrome. |

| 16:51:04 | Zevv | lqdev: once more about your AST idea; what's the ordering for nodes() |
| 16:51:29 | Zevv | is this API idea a copy of something existing somewhere else? any references? |
| 16:51:43 | FromDiscord | <lqdev> the order the AST-producing rules have been entered in |
| 16:51:53 | FromDiscord | <lqdev> as i said, it's inspired by https://pegjs.org/ |
| 16:51:57 | Zevv | ah right |
| 16:52:14 | FromDiscord | <lqdev> where you can do `exprs:(expr+)` and it will create an Array with all the expressions in it |
| 16:54:18 | Zevv | NPeg used to have that, rendering JSonNodes |

| 17:25:35 | FromDiscord | <VVX7> quick question, is there some way to make a table of procs? I'd like to be able to call a procedure using a key. I didn't see how to do this in the Tables library |
| 17:25:40 | FromDiscord | <19> ah yes it was in fmRead |
| 17:25:43 | FromDiscord | <19> d'oh |
| 17:27:11 | disruptek | vvx7: make a table where the value is a proc type. |
| 17:27:38 | disruptek | why do people insist on using tuples where they should use objects? |
| 17:27:41 | disruptek | i don't understand this. |
| 17:28:00 | FromDiscord | <konsumlamm> a proc type looks like `proc (x: int, y: string): bool` or (`(int, string) -> bool` if you import sugar) |
| 17:28:01 | disruptek | !rfc 321 |
| 17:28:02 | disbot | https://github.com/nim-lang/RFCs/issues/321 -- 3Allow to initialise Named Tuples with same notation as Objects |
| 17:28:23 | FromDiscord | <konsumlamm> (edit) "or (`(int," => "(or `(int," |
| 17:28:27 | saem | Because tuples feel like they should be reached for more often but they're never what you want |
| 17:28:44 | FromDiscord | <VVX7> Thanks, new to Nim. 😅 |
| 17:28:46 | saem | Also, they're too prominent in the manual given that's the case |
| 17:29:56 | FromDiscord | <konsumlamm> wait, that initialization syntax is not available? i had just assumed it was, lol |
| 17:30:32 | saem | Vvx7: me too, it's been pretty fun to get into and I've found I can go pretty darn deep into the language in a short amount of time so hopefully you have a similar or better experience |
| 17:32:02 | saem | That initialization syntax is also a thing, not convinced why it just be different. Feels like you gotta chase spurious syntax errors if you change your mind and isn't philosophically in line with ucfs |
| 17:35:23 | disruptek | you mean : versus =, right? |
| 17:36:19 | disruptek | i'm not so bothered by it, but maybe it makes sense for the arguments to all be identDefs. |
| 17:36:36 | disruptek | as opposed to colonexprs. |
| 17:38:36 | saem | Yeah, I do mean that |
| 17:40:22 | * | leorize quit (Ping timeout: 268 seconds) |
| 17:40:23 | disruptek | so do you want to s/objctor/newcall typesym/ also? |
| 17:40:36 | saem | I replied to your comment, I agree that there are real programming errors to avoid and when you get all the syntax makes it feel dynamic land then things that do compile maybe perhaps should get lost m but initialisation time doesn't feel like the right place to make that distinction as the errors, if they exist, are elsewhere. |
| 17:41:33 | saem | s/perhaps should/perhaps shouldn't |
| 17:43:27 | disruptek | well, yes, i agree. |
| 17:43:45 | saem | I'm not sure about the objctor vs newcall typesym case, depends on what the value of the distinction is. |
| 17:44:10 | saem | Haven't thought about that at all. |
| 17:46:44 | FromDiscord | <VVX7> not sure what I'm doing wrong here with tables https://play.nim-lang.org/#ix=2N42 |
| 17:46:46 | disruptek | i guess it should desugar to ctor because there's no reason not to. |
| 17:47:03 | FromDiscord | <19> why does `file.write(str, fmAppend)` literally append the string "fmAppend" at the end of the procedure ^_^ |
| 17:47:41 | FromDiscord | <19> @VVX7 initTable is not defined |
| 17:47:54 | FromDiscord | <lqdev> um, you want to open the file with fmAppend |
| 17:48:01 | FromDiscord | <lqdev> look at the signature of `write` |
| 17:48:27 | FromDiscord | <lqdev> https://nim-lang.org/docs/io.html#write%2CFile%2Cvarargs%5Bstring%2C%5D |
| 17:48:41 | FromDiscord | <lqdev> is what the compiler resolves your call to |
| 17:48:44 | disruptek | proc is a typeclass, not a type. |
| 17:48:45 | FromDiscord | <carpal> creating an object type that can contain multiple data types |
| 17:49:03 | disruptek | carpal: use refs. |
| 17:49:35 | FromDiscord | <carpal> `var x = newObject("hello"); x = newObject(1)` |
| 17:50:00 | FromDiscord | <lqdev> i'm just wondering what your use case for this is |
| 17:50:06 | FromDiscord | <Recruit_main707> using threads will leak memory with gc:none? |
| 17:50:23 | FromDiscord | <carpal> i need an onject may contain primitive datas and instances |
| 17:50:35 | FromDiscord | <carpal> in a vm |
| 17:50:44 | FromDiscord | <Rika> what? |
| 17:50:45 | FromDiscord | <19> sent a code paste, see https://play.nim-lang.org/#ix=2N44 |
| 17:50:52 | FromDiscord | <Rika> that still adds "fmAppend" to the end of the file |
| 17:50:58 | FromDiscord | <Rika> remove that and it should be fine |
| 17:51:07 | FromDiscord | <lqdev> well then why would you need multiple proc types |
| 17:51:46 | FromDiscord | <Rika> ~~leaking memory isnt a problem unless your program is long running or going to run on a more primitive os~~ |
| 17:51:47 | FromDiscord | <19> @Rika yes i noticed :D |
| 17:51:47 | FromDiscord | <lqdev> my VM just has a single `proc (args: openArray[Value]): Value` |
| 17:52:43 | FromDiscord | <19> but its weird it picked up the fmAppend without it having quotes |
| 17:52:50 | FromDiscord | <lqdev> well yeah |
| 17:52:55 | FromDiscord | <lqdev> beacuse fmAppend has a `$` defined |
| 17:52:55 | FromDiscord | <19> its varargs |
| 17:53:02 | FromDiscord | <carpal> maybe I'll need to an Object in next projects |
| 17:53:03 | FromDiscord | <19> oh i see now i understand |
| 17:53:08 | FromDiscord | <19> thanks guys |
| 17:53:29 | FromDiscord | <lqdev> eh, that sort of "maybe" is why you're overengineering this :) |
| 17:53:45 | disruptek | carpal: use a variant object, like we said in the very beginning. did you read the manual? |
| 17:53:48 | FromDiscord | <lqdev> if you ever need it in other projects you can just copy + paste your existing code and modify it to suit the new project's needs |
| 17:54:24 | FromDiscord | <Rika> varargs can optionally take a 2nd generic argument that converts whatever input into the desired type inside the varargs type |
| 17:54:35 | FromDiscord | <Rika> well, "generic" |
| 17:55:32 | FromDiscord | <carpal> also for this: printing a value stored in a pointer without knowing its type https://media.discordapp.net/attachments/371759389889003532/802597396852899850/unknown.png |
| 17:55:50 | FromDiscord | <19> @Rika my brain melted from reading that |
| 17:56:08 | FromDiscord | <19> but makes sense |
| 17:56:10 | FromDiscord | <19> xD |
| 17:56:14 | FromDiscord | <carpal> I didn't read the manual, bytheway I used a variant object |
| 17:56:29 | FromDiscord | <carpal> I sent a screen previously |
| 17:56:29 | FromDiscord | <19> it magically converts it |
| 17:56:40 | FromDiscord | <Rika> sent a code paste, see https://play.nim-lang.org/#ix= |
| 17:56:50 | FromDiscord | <lqdev> @19 in layman's terms, if you pass something to `varargs[T]`, it will be passed as-is and T will be expected. if you pass something to `varargs[T, C]`, then `C` will be called for every argument that's passed to varargs |
| 17:57:05 | FromDiscord | <lqdev> as a conversion routine |
| 17:57:10 | FromDiscord | <carpal> or simpler move the nimobject.nim in the standard directories and use it as a standard type ... |
| 17:57:11 | FromDiscord | <19> that's nice |

| 18:23:45 | FromDiscord | <Rika> ah fuck sorry i mean rst |
| 18:24:53 | disruptek | nimions won't use rtti because it's slow. they won't use dynamic dispatch because it's slow. they won't use introspection because it's slow. |
| 18:25:05 | disruptek | so they have all this headroom that they cannot exploit because slow. |
| 18:25:10 | disruptek | silly. |
| 18:27:20 | FromDiscord | <lqdev> hello, the cicero |
| 18:27:23 | FromDiscord | <lqdev> looks like there are slow. |
| 18:29:17 | FromDiscord | <Rika> i dont use dynamic dispatch because it feels wonkier to me than using static+generics/case objects/etc |
| 18:29:43 | FromDiscord | <lqdev> i don't use dynamic dispatch because it doesn't use vtables. |
| 18:29:55 | disruptek | so what? |
| 18:30:16 | FromDiscord | <lqdev> mratsim told me it's slower without vtables. |
| 18:30:22 | disruptek | exactly. |
| 18:30:27 | FromDiscord | <lqdev> but i dunno if i should trust him. |
| 18:30:27 | disruptek | "because slow" |
| 18:30:59 | FromDiscord | <lqdev> i swear that's the only language feature i don't use because slow |
| 18:31:31 | FromDiscord | <lqdev> introspection is done at compile time so it can't be slow |
| 18:31:43 | disruptek | it doesn't have to be. |
| 18:31:59 | disruptek | but, it won't matter if we implement it; people won't use it. |
| 18:32:12 | FromDiscord | <lqdev> let's say it together |
| 18:32:15 | FromDiscord | <lqdev> because slow :) |
| 18:32:39 | FromDiscord | <lqdev> well i would use some of those features if i did like, idk |

| 19:46:40 | FromDiscord | <JSONBash> can a `seq[float64]` be converted to `UncheckedArray[float64]` and back to a seq? |
| 19:47:38 | FromDiscord | <Rika> yes but why? |
| 19:47:43 | FromDiscord | <arun> Looking to convert some python code I have to nim just for kix. The py2nim page redirects to languist, which hasn't been updated in a couple of years. Are there other alternatives? |
| 19:47:55 | FromDiscord | <Rika> not that i know of |
| 19:48:35 | disruptek | arun: did you try languist? |
| 19:48:39 | FromDiscord | <JSONBash> because i need UncheckedArray for C interop (I beleive) and want to use seq on the nim side |
| 19:48:59 | FromDiscord | <arun> I clicked around, but didn't try to transpile anything yet. |
| 19:49:29 | FromDiscord | <arun> I've had good luck with the code base that was called py14 (python -> C++), which has subsequently been enhanced as pyrs (python -> Rust) |
| 19:49:46 | FromDiscord | <arun> I may be a bit biased because I have some experience with that code base, but none with languist. |
| 19:50:03 | disruptek | it's hard to believe, but sometimes software reaches a point where it doesn't need to be fixed. |

| 20:21:27 | FromDiscord | <Recruit_main707> i cant get an array slice as array[len / 2, T]? |
| 20:21:58 | FromDiscord | <lqdev> no because the slice is not known at compile time |
| 20:22:11 | FromDiscord | <lqdev> note it's `HSlice` not `static HSlice` |
| 20:22:35 | FromDiscord | <Recruit_main707> there is no overload for this? |
| 20:22:39 | FromDiscord | <lqdev> no |
| 20:22:40 | FromDiscord | <ITR> is there any way to use a constant variable inside a constant string? |
| 20:22:48 | FromDiscord | <lqdev> @ITR yeah |
| 20:22:53 | FromDiscord | <Recruit_main707> im surprised no one wanted to do this before me |
| 20:23:30 | FromDiscord | <lqdev> though your "constant variable (these terms are mutually exclusive btw)" must be a `const` not a `let` |
| 20:23:41 | FromDiscord | <ITR> yeah |
| 20:23:53 | FromDiscord | <JSONBash> @lqdev https://play.nim-lang.org/#ix=2N4T am i doing this right? |
| 20:24:27 | * | zndoq[m] left #nim ("User left") |
| 20:24:45 | FromDiscord | <lqdev> @JSONBash why does it need a `ptr ptr cdouble`? that means it expects an array of arrays of doubles |
| 20:25:06 | FromDiscord | <lqdev> that cast is redundant, if the type is just `ptr cdouble` |
| 20:25:46 | FromDiscord | <lqdev> so the thing is, you have your seq |
| 20:25:53 | FromDiscord | <JSONBash> const double data_in[] = {5,8,12,11,9,8,7,10,11,13}; |
| 20:26:00 | FromDiscord | <JSONBash> thats the C code example input array |
| 20:26:03 | FromDiscord | <lqdev> ahhhhh |
| 20:26:09 | FromDiscord | <lqdev> then that's easy as pie |
| 20:26:35 | FromDiscord | <lqdev> you just do `const dataIn = @[cdouble 5, 8, 12, 11, 9, 8, 7, 10, 11, 13]` |
| 20:26:44 | FromDiscord | <lqdev> and then pass `dataIn[0].unsafeAddr` to C |
| 20:27:37 | FromDiscord | <JSONBash> can the cdouble be the first element? |
| 20:28:21 | FromDiscord | <JSONBash> would that be `const dataIn: seq[cdouble] = @[1,2,3,4,5]` |
| 20:29:50 | FromDiscord | <lqdev> well not really, nim type conversions are a bit quirky in that regard |
| 20:29:54 | FromDiscord | <JSONBash> @lqdev the other part is the C function doesnt return a vlalue, it takes the ptr to the resukt array, do i just `var result: seq[cdouble] : [cdouble, res.len]` |
| 20:30:14 | FromDiscord | <lqdev> wait so it writes there right? |
| 20:30:24 | FromDiscord | <lqdev> you need to change that `const` to a `var` then |
| 20:30:59 | FromDiscord | <JSONBash> `(size: cint, inputs: ptr ptr cdouble, options: ptr cdouble, outputs: ptr ptr cdouble)` |
| 20:31:10 | FromDiscord | <JSONBash> those are the parameters |
| 20:31:26 | FromDiscord | <Rika> so thats why it takes a double ptr |
| 20:31:47 | FromDiscord | <JSONBash> yeah, sorry that I am not super clear on everything |
| 20:32:26 | saem | mumblin' |
| 20:46:08 | FromDiscord | <JSONBash> @lqdev https://play.nim-lang.org/#ix=2N50 is the updated problem with all information I am aware of |
| 20:50:29 | FromDiscord | <lqdev> @JSONBash fixed it up for you https://play.nim-lang.org/#ix=2N52 |
| 20:55:59 | FromDiscord | <JSONBash> inputAddr = input[0].addr |
| 20:56:11 | FromDiscord | <JSONBash> gives error `expression has no address; may↵10009 be use 'unsafeAddr'` |
| 20:56:23 | FromDiscord | <JSONBash> also appreciate the help, many thakns |
| 20:57:12 | FromDiscord | <JSONBash> 10009 should be ignored |

| 21:24:26 | FromDiscord | <carpal> mhh, usint unsafeAddr is not a good oractice |
| 21:24:30 | FromDiscord | <carpal> (edit) "oractice" => "practice" |
| 21:24:43 | FromDiscord | <lqdev> @carpal it's necessary though |
| 21:25:01 | FromDiscord | <lqdev> using raw pointers overall is not a good practive |
| 21:25:01 | FromDiscord | <carpal> mostly because, if the compiler says you if is because you shouldn't |
| 21:25:02 | FromDiscord | <lqdev> (edit) "practive" => "practice" |
| 21:25:22 | FromDiscord | <lqdev> the compiler can say whatever the heck it wants |
| 21:25:35 | FromDiscord | <lqdev> in this case we know that the expression does indeed have an address |
| 21:26:05 | FromDiscord | <carpal> with ket you cannot use addr |
| 21:26:18 | FromDiscord | <lqdev> as long as the C lib doesn't write there this usage is perfectly fine |
| 21:26:23 | FromDiscord | <carpal> because let are not always stored in the stack |
| 21:26:27 | FromDiscord | <lqdev> so? |

| 21:56:24 | disruptek | the reason we don't want them is that they complicate apis needlessly because people feel obligated to impl 6 different forms of result value passing and object mutation. |

| 22:37:08 | FromDiscord | <SivadNai> What do i misunderstand here https://play.nim-lang.org/#ix=2N5I i was trying to make an array of buttons, where each button has its own identifiers, but no, they all share one identifier |
| 22:48:37 | FromDiscord | <Recruit_main707> what should the name of this issue be? https://play.nim-lang.org/#ix=2N5K↵I dont know what title it should have 🥴 |
| 22:53:20 | saem | sivad: I don't even know what you mean by identifiers in that code, please shrink it down to the concept you'd like help with or make it more self-explanatory. |
| 22:53:43 | FromDiscord | <carpal> sent a code paste, see https://play.nim-lang.org/#ix=2N5N |
| 22:53:57 | FromDiscord | <carpal> (edit) "https://play.nim-lang.org/#ix=2N5N" => "https://play.nim-lang.org/#ix=2N5O" |
| 22:54:40 | * | asdflkj joined #nim |
| 22:58:42 | FromDiscord | <SivadNai> It is the result of line 52 which confuses me |
| 23:05:15 | saem | recruit: I shrunk it to this: https://play.nim-lang.org/#ix=2N5R makes it a bit more clear to me at least. I would start with something wordy and refine, eg: "array return type, with size computed from expression with generic param causes compiler crash" |
| 23:08:31 | saem | sivad it's referring to the last one, which makes sense, that's what it was initialized as last. but is a variable that has a ref to a single thing and that proc doesn't close over the dereferenced value of that var instead the var itself, which is a reference, which you're changing in your loop. |
| 23:10:01 | saem | Your even handling needs to get a hold of the button some other way, like an id wherein it can look it up in the container, aSquares, or whatever. |
| 23:10:09 | saem | s/handling/handler |
| 23:11:30 | FromDiscord | <Clyybber> @carpal You can do procedure((var outparam: type; outparam)) |
| 23:11:40 | FromDiscord | <Clyybber> And you can make a template for automating this |

| 23:14:06 | saem | Clyybber you think you'd have some time showing me a bit of your development flow when working on the compiler at some point? It feels like I'm running around in circles presently and I'm wondering how others do things might get me unstuck. |
| 23:14:35 | saem | "seeing how others do things" even. |
| 23:14:38 | * | hyiltiz joined #nim |
| 23:16:18 | FromDiscord | <Recruit_main707> saem, thanks but thats not exactly the issue i think, and it seems to have something to with the `x` parameter (?) https://play.nim-lang.org/#ix=2N5Y |
| 23:16:26 | FromDiscord | <Recruit_main707> to do |
| 23:20:22 | saem | recruit: I know, that's what I was trying to get across and maybe it's not the same conclusion you came to. The given is that it shouldn't segfault. I think perhaps you're saying that you expect both example 3 and 4 to work? |
| 23:21:27 | saem | example 3 because it's constrained to a static[int] and it's simply a compile time expression, and example 4 because T's type you feel should be inferred from the expression it's a part of? |
| 23:22:15 | FromDiscord | <SivadNai> hmm ok refs |
| 23:22:47 | FromDiscord | <carpal> let me try |
| 23:23:30 | FromDiscord | <Recruit_main707> saem, example 3, yes, in example 4 i feel like T should be inferred from arr: `array[T...`↵however, example 2 does not crash, but does not compile either |
| 23:23:58 | FromDiscord | <Recruit_main707> i dont see anything wrong in any of them |
| 23:24:06 | saem | OK, so I think if you note your expectations the title will be easier, you're pretty close. |
| 23:27:27 | saem | I don't know generics well enough in Nim, and this is pushing the limits of my understanding, but the proc is generic and it takes a type which also has a generic param. Not sure about the direction of things. The size type parameter of the array doesn't have a constraint at least in system.nim declared, but the compiler might have special handling as it's marked as magic. |
| 23:28:01 | FromDiscord | <Recruit_main707> maybe this:↵Compiler crashses when generic value should be inferred from an array and its a default value for another argument (?) |
| 23:28:53 | FromDiscord | <carpal> there's no need for template, just it works https://media.discordapp.net/attachments/371759389889003532/802681288574107658/unknown.png |
| 23:29:10 | FromDiscord | <Recruit_main707> cursed |
| 23:29:11 | FromDiscord | <Clyybber> yeah I know :) |
| 23:29:16 | FromDiscord | <Clyybber> @Recruit_main707 nah |
| 23:30:01 | saem | array has two type params, so I would specify the size param at least. |
| 23:30:49 | saem | such little code, still needs a content warning. :D |
| 23:30:53 | FromDiscord | <Clyybber> there are more cursed things to be written |
| 23:31:01 | FromDiscord | <Recruit_main707> the problem is that the title doesnt talk about why when x is explicitly marked as `x: static[int]` it can at least show an error at compile time (although its not correct afaik) |
| 23:31:37 | FromDiscord | <Recruit_main707> maybe i should leave that for another issue |
| 23:32:56 | saem | Yeah, but as a type parameter, I'm not sure if `3` is a static number or in fact a type. If it's a type not sure if Nim does type expression evaluation like that. |
| 23:37:32 | saem | actually, let me run that through the debugger and see what happens. |
