02:24:05FromDiscord<T0lk1en> First project. Check it out. https://github.com/ko-mill/NimCrypt Lmk some feedback
02:25:23FromDiscord<Rika> Remove the debug echo statements lol
02:26:01FromDiscord<scipio> well it is friendly? I feel welcome reading so many hiiiiiiiii's
02:26:09FromDiscord<T0lk1en> Oh shit🥲🥲
02:26:10FromDiscord<Rika> Lmao
02:26:27FromDiscord<T0lk1en> Happens to the best
02:26:51FromDiscord<Elegantbeef> On the plus side you didnt push a binary file
02:27:09FromDiscord<leetnewb> Feel like the debug messages need to be meaner
02:27:23FromDiscord<T0lk1en> I like a friendly program
02:27:41FromDiscord<scipio> I'd throw in a `when` and leave 'em in there as easter eggs
02:27:49FromDiscord<T0lk1en> In reply to @Rika "Remove the debug echo": Removed them
02:27:58FromDiscord<scipio> put 'em back
02:28:00FromDiscord<T0lk1en> What does when do?
02:28:11*byanka joined #nim
02:28:16FromDiscord<scipio> `when` is a compile time i`f`
02:28:21FromDiscord<scipio> (edit) "i`f`" => "`if`"
02:28:22*jmdaemon quit (Ping timeout: 272 seconds)
02:28:31FromDiscord<T0lk1en> Purpose?
02:29:00FromDiscord<scipio> 42
02:29:10FromDiscord<Elegantbeef> Optional compilation of logic depending on flags or types
02:29:20FromDiscord<T0lk1en> Wyd does that mean?
02:29:23FromDiscord<T0lk1en> Wtf
02:29:50FromDiscord<Rika> In reply to @leetnewb "Feel like the debug": Like “fuck you”?
02:30:00FromDiscord<T0lk1en> Like wanting to do logic outside the program during compile time?
02:30:06FromDiscord<Rika> In reply to @T0lk1en "Like wanting to do": Yes pretty much
02:30:19*byanka_ quit (Ping timeout: 260 seconds)
02:30:22FromDiscord<T0lk1en> Why would you want something that does logic on compile time vs when you run it?
02:30:30FromDiscord<Rika> Like if you want to put debug statements only when compiling a debug binary
02:30:32FromDiscord<Elegantbeef> When compiled wiht `-d:doEcho` it will print "hello" otherwise it doesnt do anything
02:30:32FromDiscord<Elegantbeef> This extends to generics and the like
02:30:41FromDiscord<Elegantbeef> sent a code paste, see https://paste.rs/JY2
02:30:57FromDiscord<T0lk1en> Ah so basically optional debug statements
02:31:43FromDiscord<T0lk1en> Cool
02:32:02FromDiscord<T0lk1en> But lmk what you guys think. I’m trying to learn and get better
02:32:05FromDiscord<Rika> Not the only use of course
02:32:09FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=4kRf
02:32:30FromDiscord<Elegantbeef> Another usage of `when`
02:32:30FromDiscord<Elegantbeef> Thinking of it as a compile time `if` is generally sufficient, but it behaves differently
02:32:30FromDiscord<Elegantbeef> It's not that it runs at compile time
02:32:31FromDiscord<Elegantbeef> It changes the program based off constant expressions
02:32:31FromDiscord<Elegantbeef> Which means you can specialise for types or just optionally emit code
02:32:31FromDiscord<Elegantbeef> One use of using `when` is to include debug statements only if build with the debug flag
02:32:33FromDiscord<Elegantbeef> Otherwise you dont have the overhead of debug logic
02:32:45FromDiscord<Rika> Beef typing at the speed of light (joke)
02:32:55FromDiscord<Rika> Bridge just being slow I assume
02:33:00FromDiscord<Elegantbeef> There isnt much to comment on
02:33:00FromDiscord<Elegantbeef> It's 12 loc
02:33:06FromDiscord<Elegantbeef> Matrix bridge is slow, but i'm fast
02:33:07FromDiscord<Elegantbeef> Or vice versa
02:42:41FromDiscord<T0lk1en> Interesting
02:44:31FromDiscord<scipio> In reply to @T0lk1en "First project. Check it": other than that, 2 things:↵-1- 25 lines of code (which could be rewritten to about half the size) isn't exactly "publishable", right? What kind of feedback would you expect on this? Kind of "storming / kicking in an already open door".↵↵-2- it's good you're learning and having fun! Keep at it! 🙂
02:46:33FromDiscord<T0lk1en> Ig I didn’t know what to expect. Maybe something about if it’s actually useful or not.

02:50:51FromDiscord<T0lk1en> Gotchu bro
02:50:57FromDiscord<T0lk1en> @scipio
02:52:03FromDiscord<voidwalker> is there any way I can assign to an enum value, a type value of another enum type ?
02:52:44FromDiscord<Elegantbeef> `myEnum = MyEnumType(myOtherEnum)`
02:53:14FromDiscord<auxym> wow, I still haven't finished parsing the question
02:53:31FromDiscord<voidwalker> lol I don't think I wrote it properly
02:53:34FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=4kRi
02:53:49FromDiscord<Elegantbeef> I assume you want to assign a enum of a different type to a enum of this tpye
02:54:04FromDiscord<voidwalker> hm no
02:54:15FromDiscord<Elegantbeef> Well then get to using your words
02:54:36FromDiscord<voidwalker> I want an enum value to hold, like it can hold a string, the "value" (like in typedesc?) of another Enum type
02:54:44FromDiscord<voidwalker> so that they are logically linked
02:55:20FromDiscord<Elegantbeef> I mean you can do `myEnumField = $myOtherEnumField`
02:55:39FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=4kRj
02:55:41FromDiscord<voidwalker> well it's not field to field, it's field to type
02:55:42FromDiscord<auxym> or `int(myOtherEnumField)`
02:55:58FromDiscord<Elegantbeef> You need to provide a problem in code
02:56:07FromDiscord<Elegantbeef> Your words are failing you like i did highschool

02:56:11FromDiscord<Elegantbeef> There you go
02:56:12FromDiscord<voidwalker> I want aom to hold "AomParams" type
02:56:28FromDiscord<Elegantbeef> Hold it how?
02:56:33FromDiscord<auxym> types cannot be used as values
02:56:34FromDiscord<voidwalker> as a value 😄
02:56:36FromDiscord<voidwalker> no ?
02:56:43FromDiscord<voidwalker> I thought that's what typedesc is for
02:56:56FromDiscord<auxym> as runtime values
02:57:00FromDiscord<voidwalker> I need it to get rid of a layer of abstraction
02:57:07FromDiscord<Elegantbeef> Typedescs do not exist at runtime
02:57:11FromDiscord<Elegantbeef> They're purely a compile time construct
02:57:15FromDiscord<voidwalker> oh..
02:57:20FromDiscord<Elegantbeef> I dont know what relation you're going for still
02:57:46FromDiscord<voidwalker> related to this: https://forum.nim-lang.org/t/9816 where I have this implemented: https://play.nim-lang.org/#ix=4kRg
03:00:29FromDiscord<voidwalker> sent a code paste, see https://paste.rs/h9E
03:00:54FromDiscord<Elegantbeef> The only way around this is a macro of some form
03:01:00FromDiscord<voidwalker> which adds one more useless layer in the object's nodes of values
03:01:11FromDiscord<Elegantbeef> You want to conditionally flow types based off runtime value, which means you need branching
03:02:34FromDiscord<Elegantbeef> Atleast as far as i can tell you want to change types used based off what value is parsed
03:02:45FromDiscord<Elegantbeef> Alternatively you could just use a `seq[(string, string)]`
03:02:53FromDiscord<Elegantbeef> Or `(int, string)`
03:03:23FromDiscord<voidwalker> yeah, I want to be able to pass the proper type based on a value I already know it should point to that type

03:27:46FromDiscord<Elegantbeef> That's the point of the set, you can share them if you need but getting which ones are valid are easy

04:39:05FromDiscord<m4ul3r> What args are you giving to encrypt or decrypt?
04:40:14FromDiscord<T0lk1en> A valid file name and a valid aes 16 length key
04:40:36FromDiscord<T0lk1en> It’s almost gotta be a problem w the library
04:41:16FromDiscord<T0lk1en> Yeah it is I’m getting errors on the example code now
04:43:16FromDiscord<m4ul3r> Just tested it, works for me so it isn't a problem with the library
04:43:34FromDiscord<T0lk1en> Lemme delete and redownload the library rq
04:44:25FromDiscord<T0lk1en> Does my code work on your machine?
04:46:42FromDiscord<m4ul3r> let me test
04:47:09FromDiscord<T0lk1en> I left my GitHub earlier
04:48:36FromDiscord<m4ul3r> You're using contents with `aes.encryptECB()` which isn't the key
04:49:15FromDiscord<m4ul3r> contents is probably not 16 and that's why it is failing
04:50:55FromDiscord<T0lk1en> I just deleted the portion of code in the library that was cashing me problems and everything works perfect now. Let’s see if I fucked up big or not
04:53:55FromDiscord<m4ul3r> According to the repo (https://github.com/jangko/nimAES) the implemented AES only works on 1 bock (16 bytes).↵You'd have to implement iteration of each block yourself,
05:00:07*oprypin quit (Quit: Bye)
05:07:11FromDiscord<jtv> Wow, the compiler on OS X runs under rosetta?
05:12:26FromDiscord<jtv> I mean, it definitely does, as I discovered on accident. Why's that the case I guess is the question 🙂
05:12:54FromDiscord<T0lk1en> In reply to @m4ul3r "According to the repo": Wdym
05:14:10FromDiscord<m4ul3r> In reply to @T0lk1en "Wdym": https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation↵ECB is a block cipher, so you would encrypt each block of your data one by one. The library only support 1 block for AES-ECB
05:14:13FromDiscord<T0lk1en> Do I have to portion out my data into 16 but lengths an encrypt it one by one?
05:14:33FromDiscord<jtv> Oh my god, if you do that, it's insecure.
05:14:43FromDiscord<m4ul3r> ecb is insecure yes
05:14:53FromDiscord<T0lk1en> Wtf what is secure
05:14:54FromDiscord<jtv> No, ECB mode is just running the block cipher
05:15:03FromDiscord<jtv> Repeating input, key pairs is insecure
05:15:08FromDiscord<T0lk1en> It seems every time I ask everything is insecure
05:15:11FromDiscord<T0lk1en> Rsa
05:15:12FromDiscord<T0lk1en> AES
05:15:18FromDiscord<T0lk1en> What IS secure
05:15:32FromDiscord<Elegantbeef> If you compile from source it runs on arm
05:15:35FromDiscord<jtv> Right, like I told you, even cryptographers have an incredibly difficult time getting things right.
05:15:56FromDiscord<T0lk1en> This is fucked I’m writing my own encryption
05:15:59FromDiscord<jtv> Ahhh, thanks. I figured I'd have to compile the C myself, so that's good to know, will do
05:16:10FromDiscord<jtv> Yes, rule #1, remember?
05:16:24FromDiscord<T0lk1en> In reply to @jtv "Yes, rule #1, remember?": Which is?
05:16:34FromDiscord<jtv> DON'T ROLL YOUR OWN ENCRYPTION
05:16:38FromDiscord<jtv> You forgot already? 🙂
05:16:52FromDiscord<T0lk1en> That’s right
05:17:45FromDiscord<T0lk1en> Okay here’s 2 questions. What is secure cause y’all got me thinking that encryption just doesn’t exist. #2 what makes something good
05:17:50FromDiscord<T0lk1en> Encryption wise
05:18:16FromDiscord<m4ul3r> Looks at the wiki i sent you
05:18:17FromDiscord<jtv> Well, everything can easily be insecure if you don't use it the way it was intended to be used
05:18:36FromDiscord<jtv> For password storage, there are a LOT of considerations to doing it right
05:19:02FromDiscord<jtv> Meaning, I teach a whole 3 hour class and don't scratch the surface on it
05:19:21FromDiscord<jtv> For most day-to-day stuff, TLS is your best bet.
05:19:32FromDiscord<m4ul3r> AES-CBC is more secure than AES-ECB, nimAES supports n blocks for AES-CBC
05:19:37FromDiscord<jtv> Oh my god, no
05:19:41FromDiscord<T0lk1en> is there a tls nim library?
05:19:54FromDiscord<jtv> CBC no cryptographer has used for 15+ years, and it was removed from TLS1.3
05:20:09FromDiscord<jtv> Just having to pad alone causes problems
05:20:20FromDiscord<T0lk1en> What’s tls
05:20:46FromDiscord<jtv> "Transport Layer Security", the protocol that encrypts virtually all encrypted IP-level traffic
05:20:53FromDiscord<m4ul3r> i didn't say CBC was insecure, just that it's more secure than ECB
05:21:43FromDiscord<m4ul3r> t0lk1en seems to be working on a project to practice encryption, so i'm just giving them suggests
05:21:51FromDiscord<T0lk1en> Yerrr
05:22:17FromDiscord<jtv> Yeah, that'd still be a horrible approach for this problem.
05:22:17FromDiscord<T0lk1en> Fuck all this noise tho I’m gonna write my own encryption library.
05:22:20FromDiscord<Rika> I think encryption and security are topics that are not a good idea to self study
05:22:30FromDiscord<m4ul3r> math is hard
05:22:36FromDiscord<jtv> Agreed, 1000% which is what I told him before he started the project
05:22:38FromDiscord<T0lk1en> I’m not. Cyber security major
05:22:56FromDiscord<Rika> Then what is the course you’re following that makes you write this code?
05:23:34FromDiscord<T0lk1en> They don’t ig you are right. Just figured I wanna learn more and have a good looking GitHub page
05:24:07FromDiscord<Rika> Look, sorry that some people here are real aggressive with how they put it
05:24:22FromDiscord<Rika> But security isn’t easy, it isn’t even just difficult
05:24:33FromDiscord<jtv> I've still been helping him, just making it clear it's not going to be secure 🙂
05:24:44FromDiscord<T0lk1en> Ik it’s not^^^
05:25:07FromDiscord<Rika> JTV we know you’re a cryptographer or whatnot but damn can you be a bit more chill
05:25:09FromDiscord<T0lk1en> I’m on windows rn anyways nothing I do is secure lol
05:25:14FromDiscord<jtv> Lol
05:25:24FromDiscord<T0lk1en> lol I think everyone has been chill
05:25:30FromDiscord<m4ul3r> I think your ECB is a good project to work on. Implement a way to pad your incoming data, then iterate over each block using nimAES to encrypt. Same with decrypting
05:25:37FromDiscord<T0lk1en> It’s hard to understand tone over text
05:25:54FromDiscord<jtv> Tolk1en, that library has gcm mode; use that, but make sure you use the version of the API where you store the output PLUS the tag, and check it on decryption
05:26:07FromDiscord<T0lk1en> In reply to @m4ul3r "I think your ECB": I’m fr gonna write my own encryption library
05:26:12FromDiscord<jtv> Otherwise you will have problems where the bits can be flipped on you and you won't know it
05:26:34FromDiscord<Rika> Creating is much harder than using
05:26:51FromDiscord<m4ul3r> I mean, whatever gets you learning with encryption
05:26:59FromDiscord<m4ul3r> if that's your end goal
05:27:03FromDiscord<T0lk1en> Dudes I just realized why the example problem worked. The fucking input was 16 bits holy
05:27:07FromDiscord<jtv> The nonce is supposed to be a 12 byte random value, which should be the salt for your password.
05:27:17FromDiscord<T0lk1en> Salt?
05:27:51FromDiscord<m4ul3r> In reply to @T0lk1en "Dudes I just realized": yes, i said it only worked on one block at a time. It's written with 16 byte blocks (128 bits)
05:27:59FromDiscord<T0lk1en> I realize now
05:28:37FromDiscord<m4ul3r> You can implement what I suggested above and encrypt larger data than 1 block at a time
05:28:39FromDiscord<jtv> Without salt, you're going to be susceptible to precomputed cracking
05:28:52FromDiscord<T0lk1en> Wdym salt?
05:28:58FromDiscord<T0lk1en> Like fake data?
05:28:59FromDiscord<jtv> I just saw you're not using nimcrypto, it's a slightly better library to start with
05:29:05FromDiscord<T0lk1en> “Salted” over
05:29:23FromDiscord<T0lk1en> Nim crypto threw errors for me but I’ll give it a look
05:29:35FromDiscord<jtv> No, it was the state of the art in password management in 1972
05:29:43FromDiscord<jtv> But it's the basics.
05:29:55FromDiscord<jtv> Any article about storing passwords in the world would give you a good intro to salt
05:29:59FromDiscord<T0lk1en> But also. Why is nothing documented. I have trouble reading code to figure out what something does
05:30:19FromDiscord<T0lk1en> Like nimAES library
05:30:37FromDiscord<jtv> That's not a commonly used library. nimcrypto is the one people use most
05:31:01FromDiscord<m4ul3r> @T0lk1en I recommend checking out https://cryptopals.com/ if you want practice coding crypto stuffs in nim. Start small and work your way up
05:31:02FromDiscord<T0lk1en> So nimcrypto has docs I can read to know exactly how to use it?
05:31:37FromDiscord<jtv> I didn't say THAT :). I think it has some docs, but a lot of people here will have used it
05:32:01FromDiscord<m4ul3r> nimcrypto has examples, here one for ecb https://github.com/cheatfate/nimcrypto/blob/master/examples/ecb.nim
05:33:11FromDiscord<m4ul3r> nim crypto docs are pretty bare https://cheatfate.github.io/nimcrypto/
05:33:48FromDiscord<m4ul3r> nvm, they're fine
05:35:07FromDiscord<m4ul3r> looking at the examples and docs together would be good
05:36:21FromDiscord<jtv> Yeah, though there are some things done wrong, like their API doesn't implement the gcm spec properly; the last person here who was using it wasn't actually getting the integrity check on their code because of the way the API is designed ( and I believe the example doesn't get it right either)
05:37:18FromDiscord<T0lk1en> Gotcha
05:37:36FromDiscord<T0lk1en> I still think I would be fun to make my own library
05:38:13FromDiscord<jtv> It would be, sure
05:42:07FromDiscord<T0lk1en> Here’s a question. If all of our program are compiled to assembly how come some program only work on windows not Linux and some work on ARM but some don’t.
05:42:11*byanka quit (Read error: Connection reset by peer)
05:42:31FromDiscord<Elegantbeef> Arm and amd64 are different assembly
05:42:46FromDiscord<T0lk1en> If it’s all converted to C and assembly can’t any program be compiled for any architecture and OS
05:43:19FromDiscord<jtv> If the C is portable and the libraries that are dependencies exist on those platforms, then generally
05:43:44FromDiscord<T0lk1en> Well the dependencies can be converted too correct?
05:44:11FromDiscord<jtv> Well, sometimes not easily, like if they're heavily dependent on OS-specific functionality
05:44:19FromDiscord<T0lk1en> Hmm
05:44:40FromDiscord<T0lk1en> Like the WinGUI library prob would t worn on Linux huh
05:44:45FromDiscord<T0lk1en> Work
05:45:57FromDiscord<jtv> Unless you want to install Wine, then some stuff that they emulate would work, etc
05:50:20FromDiscord<T0lk1en> Got it
05:50:55FromDiscord<T0lk1en> Ty sm for all your help. It’s prob not fun to answer these easy questions

08:55:50FromDiscord<Elegantbeef> Actually you're using a template so you need to use `%` basically
08:56:01FromDiscord<pyolyokh> an example of an attempt that I came up with after reading the manual is
08:56:01FromDiscord<pietroppeter> In reply to @Rika "damn that was a": better late than never 🙂

08:56:37FromDiscord<pietroppeter> In reply to @willyboar "<@&371760044473319454> link in announcements": that's a very weird link indeed, created also a forum thread
08:57:27*Guest93 quit (Quit: Client closed)
08:58:43FromDiscord<pyolyokh> the `%` solution works. I just still feel like I'm missing a trick with templates.
08:59:18FromDiscord<willyboar> In reply to @pietroppeter "that's a very weird": I've seen both. But someone must fix this for the newcomers.
08:59:26FromDiscord<pyolyokh> but this is weird stuff that has exact expectations about the caller, it makes sense for it not to compose well
08:59:31FromDiscord<Gumbercules> sent a code paste, see https://play.nim-lang.org/#ix=4kSj
08:59:43FromDiscord<Elegantbeef> Nope templates are code subsitution so `n`, `l` and `h` do not exist
09:00:10FromDiscord<Gumbercules> (edit) "https://play.nim-lang.org/#ix=4kSj" => "https://play.nim-lang.org/#ix=4kSk"
09:01:34FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=4kSm
09:01:47FromDiscord<pyolyokh> In reply to @Gumbercules "what is `ref n`": manual says ... I misread it, and I shouldn't be using ref, but `N = n`. That's why try #8 gets me, trying to get something to work.
09:02:11FromDiscord<Elegantbeef> The key is `inject`
09:02:21FromDiscord<Elegantbeef> Symbols inside a template are gensym'd
09:02:34FromDiscord<Elegantbeef> Which means they're not accessible in any other way except as the symbol name
09:02:46FromDiscord<Elegantbeef> So you need to tell the compiler "I want this symbol to be inserted verbatim
09:03:27FromDiscord<Gumbercules> couldn't you mark the template as `dirty` as well?
09:03:54FromDiscord<Elegantbeef> Correct
09:03:54FromDiscord<Elegantbeef> I'm just silly and avoid dirty templates
09:04:05FromDiscord<Gumbercules> clean boi
09:04:11FromDiscord<pyolyokh> sent a code paste, see https://play.nim-lang.org/#ix=4kSo
09:04:33FromDiscord<pyolyokh> so the trick I was missing was `{.inject.}`, just need to be more careful with it. Thanks!
09:04:41FromDiscord<Elegantbeef> Of course it doesnt
09:04:42FromDiscord<Elegantbeef> templates replace all usages of their parameters
09:04:47FromDiscord<Gumbercules> https://nim-lang.org/docs/manual.html#templates-hygiene-in-templates
09:04:48FromDiscord<Elegantbeef> so if you do `numberBetween("a", 0, 0)` it does `let "a" {.inject.} = "a"`
09:05:21FromDiscord<pietroppeter> In reply to @willyboar "I've seen both. But": the weird thing is that in the feed.xml https://nim-lang.org/feed.xml the link is correct: https://nim-lang.org//blog/2023/01/11/this-month-with-nim.html maybe some issue on monitorss bot? or is it taking it from somewhere else?

10:10:12FromDiscord<pyolyokh> don't believe so. With a localdeps repo you can blow away nimbledeps and run `nimble install -l -d` and then compare versions to see if nimble grabbed newer ones.
10:14:30FromDiscord<fbpyr> ah I see. thank you @pyolyokh .↵I was pondering over searching a package with --ver and getting the highest version of that to compare vs. installed.↵but maybe `nimble update` followed by a compare via the retrieved packages.json is simpler approach. 🤔

11:05:40FromDiscord<htac> sent a long message, see http://ix.io/4kSP

11:07:28FromDiscord<htac> Thank you! 😊
11:09:02FromDiscord<htac> that's better, thanks!
11:09:29FromDiscord<htac> I would expect the following output running this program:
11:09:57FromDiscord<htac> sent a code paste, see https://play.nim-lang.org/#ix=4kSR
11:10:52FromDiscord<htac> but, iterating over foo the second time in run, ABC becomes garbled, a random memory string
11:12:08FromDiscord<pyolyokh> what's the /FS flag do?
11:12:09FromDiscord<htac> any clou why that might be? Iterating over an index always works...
11:13:43FromDiscord<htac> it shows the same behaviour without it: apparently, VCC's multiprocessor compilation struggles with multiple access to its debug symbol file, /FS regulates access to it.
11:14:01FromDiscord<htac> In reply to @pyolyokh "what's the /FS flag": it shows the same behaviour without it: apparently, VCC's multiprocessor compilation struggles with multiple access to its debug symbol file, /FS regulates access to it.
11:14:41FromDiscord<pyolyokh> I'm just trying to replicate what you have on Linux with different flags. With --std=c++14 I get a null pointer dereference on the `s.a = createString("ABC")`

11:20:08FromDiscord<pyolyokh> yeah. what fixes it is changing `var s: Stuff` to `var s = Stuff()`
11:20:31FromDiscord<pyolyokh> in `proc run`
11:21:55FromDiscord<htac> I did try that too, same result for me
11:22:14FromDiscord<htac> do you always get ABC now?
11:23:27FromDiscord<pyolyokh> yep, my output is what you expect
11:23:38FromDiscord<htac> very strange
11:24:07FromDiscord<htac> you do not have access to MSVC by any chance? 😊
11:24:32FromDiscord<htac> as I suspect a problem in regards with the codegen for this compiler...
11:24:49FromDiscord<pyolyokh> I don't. You have `foo = Vector[Stuff]()` at the toplevel, which differs from `foo: Vector[Stuff]` in `proc run`. How does it work to change proc run to initialize both of them with explicit constructor calls?
11:25:15FromDiscord<htac> (edit) "in" => "with" | "with" => "to"
11:26:01FromDiscord<htac> same behaviour, as it should be, since from C++'s side, the default constructor MUST be invoked
11:26:35FromDiscord<pyolyokh> OK. Well that it matters for Stuff is a bug already on gcc on linux, in my environment.
11:28:07FromDiscord<pyolyokh> sorry I can't more. My guess is that there are some surprisingly lifetime methods called in the case that you loop over foo's items, instead of looping over indices
11:28:16FromDiscord<pyolyokh> (edit) "surprisingly" => "surprising"
11:28:22FromDiscord<pyolyokh> (edit) "sorry I can't ... more." added "help"
11:28:32FromDiscord<htac> I've also tried these bindings mentioned in the Nim 2 RC post: https://github.com/Clonkk/nim-cppstl
11:28:33FromDiscord<htac> same trouble
11:30:07FromDiscord<htac> In reply to @pyolyokh "sorry I can't help": Yes, exactly, I suspect lifetime issues as well. I try to understand the differences between running the code in the implicit main and in run(), but I utterly fail in isolating the cause
11:31:07FromDiscord<htac> Anyways, thanks a lot for your time and effort! 👍

11:55:05FromDiscord<htac> (edit) "foo," => "foo" | "way," => "way"
11:55:18FromDiscord<pyolyokh> no, the for loop itself is fine.
11:55:39FromDiscord<htac> I just don't get it
11:56:29FromDiscord<pyolyokh> the next thing I'd do is write some C++ classes that announce their lifetime functions, and wrap those in place of std::vector and std::string

12:45:11FromDiscord<sOkam!> Is it possible to create a `define` in code?
12:46:09PMunchsOkam, what do you mean?
12:46:24FromDiscord<sOkam!> such that when other part of the code does `when defined something: doThing`... it automatically passes as defined without having to add `-d:something` in the compiler
12:46:27PMunchLike have some condition in your code that triggers eg. -d:ssl?
12:46:39PMunchAh, no that's not possible AFAIK
12:46:50PMunchYou can of course do it in a config.nims file
12:47:17PMunchSo you could have e.g. `when defined(windows): <windows specific switches here>`
12:48:03PMunchSince Nim really only does a single pass over all your sources it would mean that other `when` switches could silently fail and create all sorts of issues
12:48:04FromDiscord<sOkam!> yeah, but im creating some nimpretty alternative version, and I don't need to specify `-d:nimpretty` because it is assumed in the code that im writing that it will always be active. but the compiler parser needs it to give access to one of the fields
12:49:48FromDiscord<sOkam!> Here: https://github.com/nim-lang/Nim/blob/b68b28fd2448b15e989b9e8b07e33eee4f9b8822/compiler/parser.nim#L75-L76↵And there are other places in the file where it needs the define

13:05:05FromDiscord<arkanoid> @sealmove\: thanks for the updates on binarylang
13:06:19PMunch@luteva, easiest is probably to have a look at how the log-replay utility does it: https://github.com/PMunch/nimlsp/blob/master/tests/logrunner.nim
13:07:12FromDiscord<sealmove> In reply to @arkanoid "<@173424250319929344>\: thanks for the": are you still using it? i think i lost you as a binarylang user :p
13:08:04PMunchBasically if you set your editor to use `nimlsp_debug` instead of the typical `nimlsp` binary it will produce a log that shows all the messages back and forth. Then you can feed such a log-file to that utility and it will start a new nimlsp instance and replay the log. I plan to use this for debugging, people can just record their bug, submit the log, and I can tweak nimlsp until it does the right thing.
13:08:37PMunchThe actual communication is pretty simple, start nimlsp and write commands over stdin to it, then read its stdout to see the reply
13:10:42FromDiscord<luteva> thx!
13:14:41om3gadjazz , I found the problem, what causes the code we discussed early to compile
13:14:57om3gathat function mismatches with the prototype declaration in C header file from the lib
13:15:10om3gaIn header file : LV2_SYMBOL_EXPORT const LV2_Descriptor* lv2_descriptor(uint32_t index);
13:15:26FromDiscord<arkanoid> Sure, thing! Your lib is processing dozen of messages per second on average on my gps server↵(@sealmove)
13:15:28om3gaif I comment out it, the lib in nim compiles without any problem. But... absence of prototype affects the result - the lib not loads in the host
13:15:58om3gaHost reports with expected err: Could not find the LV2 Descriptor in the plugin library
13:16:14om3gaDirectives {.exportc, cdecl.} generate following code: N_LIB_PRIVATE N_CDECL(LV2_Descriptor*, lv2_descriptor)(unsigned int index) what is not the same as prototype: __attribute__ ((visibility ("default"))) const LV2_Descriptor* lv2_descriptor(uint32_t index)

14:52:07FromDiscord<sOkam!> how do you check if a string path is either a folder or a file?

14:53:29FromDiscord<Gumbercules> Or isFile
14:53:30FromDiscord<sOkam!> strutils or os?
14:53:34FromDiscord<Gumbercules> Os
14:53:51FromDiscord<sOkam!> was searching for that in os and didn't find it. will search better 😔
14:53:54FromDiscord<sealmove> In reply to @arkanoid "You have no idea": Ok at least 2 people are still using it actively. This is motivates me sufficiently. I haven't maintained it for 1.5 year, but I guess it's never too late.,
14:54:27FromDiscord<sOkam!> it actually doesn't show in search in the web
14:54:30FromDiscord<sOkam!> you sure its os?
14:54:36FromDiscord<Gumbercules> In reply to @sOkam! "was searching for that": Let me find it
14:55:20FromDiscord<Nilts> In reply to @sOkam! "it actually doesn't show": https://nim-lang.org/docs/os.html#fileExists%2Cstring

14:55:45FromDiscord<sOkam!> is that the same thing?
14:56:47FromDiscord<Gumbercules> Yeah
14:56:58FromDiscord<sOkam!> i guess it is, and also checks for existance. misleading name, but kindof makes sense
14:57:00FromDiscord<Nilts> In reply to @sOkam! "is that the same": It checks if the file exists on the system, you would probably have to use a path parsing thing to find out just if it is a dir or not

14:57:56FromDiscord<Gumbercules> you can also get a `FileInfo` I believe
14:57:57FromDiscord<Gumbercules> and check that way
14:58:05FromDiscord<sOkam!> if the file doesn't exist, just dont add the string to the seq[string] of processing files 🤷‍♂️
14:58:06FromDiscord<Gumbercules> I was getting confused with Odin I guess
15:10:41om3gadjazz, it worked, only little bit differently I did that.. but, here goes another problem, I printed all the symbols from the dylib
15:10:45om3ga00000000000041c8 S _descriptor__correlometer_109
15:11:30om3gaand it should be 0000000000000c00 T _lv2_descriptor
15:13:12om3gaI will try to declare the lv2_descriptor in .emit
15:14:34*PMunch quit (Quit: Leaving)

19:07:49FromDiscord<djazz> ayy nice
19:08:03om3gacorrelometer, calculates correlation of phase between 2 inputs
19:09:00om3gabut it's partially in nim, idk how to avoid using .emit
19:11:44om3gathe structure of lv2_descriptor should be defined as static const LV2_Descriptor descriptor
19:14:04om3gathis is what I was unable to translate to nim. const descriptor = LV2_Descriptor(...) not works
19:15:32om3gaand in case of regular nim default symbol export, the prototype of the lv2_descriptor function should be commented out
19:16:00om3gawhat is not very good, since this is lib code modification
19:16:38om3gaalso plugin "works" but, not really with the real audio data
19:17:18om3gaI should find the way how to read samples from the buffer provided as void* - data: poiner (in nim)
19:18:38om3gaI could have ability to read buff as array - var input: ptr float32
19:20:43om3gaI tried to use UncheckedArray.. but seems it gets address of buff and tries to calculate the correlation of them

20:54:24FromDiscord<MadScientistCarl> Hello, I just want to ask if there are any good embedded scripting options for Nim
20:55:19FromDiscord<sOkam!> In reply to @MadScientistCarl "Hello, I just want": I'd argue nim itself counts as a scripting language, because of HotCodeReloading and its python-like syntax
20:56:16FromDiscord<MadScientistCarl> How to embed it, though
20:56:30FromDiscord<jos> wasm probably?
20:56:36FromDiscord<jos> u can also compile to js i guess
20:56:50FromDiscord<jos> u can also use nimscript
20:57:14FromDiscord<jos> wasm is probably safer + more portable + more features, but also least developed
20:57:18FromDiscord<MadScientistCarl> I will be using the C backend
20:57:35FromDiscord<MadScientistCarl> I mean my main application will be using C backend
20:57:41FromDiscord<jos> i mean building the "plugins" into wasm modules
20:57:51FromDiscord<jos> and then embedding a wasm runtime like wasmtime
20:57:56FromDiscord<jos> i'm not sure if anyone has done this before
20:58:16FromDiscord<MadScientistCarl> OK, but that might be too complicated a workflow
20:58:30FromDiscord<MadScientistCarl> Can nimscript VM be embedded directly into a Nim program?
20:58:36FromDiscord<jos> i think so, yeah
20:58:36FromDiscord<jos> https://github.com/beef331/nimscripter
20:58:41FromDiscord<jos> i agree this is probably the lowest effort
20:58:57FromDiscord<jos> i have no clue what the status of NimScript is
20:59:06FromDiscord<MadScientistCarl> Surprised this isn't in stdlib 🙂
21:10:15FromDiscord<auxym> In reply to @jos "i have no clue": status? nimscript is here to stay, mostly because it is used to evaluate macros
21:12:59FromDiscord<jos> sure, but it doesn't support a lot of features + doesn't have a lot of pedigree for embedding
21:13:06FromDiscord<jos> i think it's safe to say "you're on your own"
21:13:20FromDiscord<MadScientistCarl> Are there anything in stdlib that helps embedding nimscript?
21:13:21FromDiscord<jos> or at least "it's called _Nim_Script but temper your expectations"
21:16:17FromDiscord<ShalokShalom> @MadScientistCarl I know you, just not anymore from where

21:41:24FromDiscord<ShalokShalom> Vulkan binding?
21:41:37FromDiscord<MadScientistCarl> Yes
21:41:39FromDiscord<ShalokShalom> You mean with no dedicated gaming libraries?
21:41:43FromDiscord<MadScientistCarl> No

21:42:23FromDiscord<ShalokShalom> I see 🙂
21:42:30FromDiscord<ShalokShalom> Much fun, then!
21:42:40FromDiscord<ShalokShalom> Nim has many amazing libraries for this
21:42:45FromDiscord<MadScientistCarl> So I am sampling a bunch of languages
21:42:48FromDiscord<ShalokShalom> And Gumber is surely happy to help you 😄
21:43:06FromDiscord<MadScientistCarl> I tried plain C, C++, Rust, Kotlin

22:01:24FromDiscord<Phil> I think I'm just missing a fundamental piece somewhere that should make it click, I don't really have much knowledge of image manipulation in general, other than that the raw form of image data is every pixel being a tuple of RGB data

22:23:20FromDiscord<guttural666> no problem haha, but same output
22:24:13FromDiscord<guttural666> I think passing in func_id which is a type func_id = enum is equivalent to the T in proc pls [T: enum]?
22:25:05FromDiscord<guttural666> required type for list: T: typedesc[enum] or seq[string]↵ but expression 'func_id' is of type: typedesc[func_id]
22:25:07FromDiscord<guttural666> both times
22:26:22FromDiscord<guttural666> my goal is to have a generic input that I can iterate over and that should work with values that are either enum types or sequences right
22:26:24FromDiscord<guttural666> think that makes sense
22:28:56FromDiscord<Elegantbeef> `T: typedesc[enum] or seq[string]` does not bind how we want
22:29:01FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=4kW6
22:29:08FromDiscord<Elegantbeef> So we need to use an implicit generic

22:30:32FromDiscord<scipio> Aloha
22:30:41FromDiscord<Elegantbeef> I mean `T: typedesc[enum] or seq[string]` is the same as `T: enum or seq[string]`
22:31:38FromDiscord<Elegantbeef> Anywho just trust the implicit generic works and carry on
22:31:49FromDiscord<guttural666> In reply to @Elegantbeef "I mean `T: typedesc[enum]": that's what I thought yes
22:32:38FromDiscord<guttural666> don't get what the difference to my solution is, just syntactic sugar no?
22:33:12FromDiscord<Elegantbeef> It's supposed to be, but there is some semantic difference to the compiler

23:20:02FromDiscord<scipio> I was trying to word my question as if you would, but it's actually me
23:20:05FromDiscord<scipio> 😁

23:21:19FromDiscord<Elegantbeef> See i personally like owlkettle but i doubt it's as feature complete as you'd need
23:21:32FromDiscord<Elegantbeef> Same for fidget/nimx
23:21:42FromDiscord<Elegantbeef> I also dont really write GUI programs
23:21:57FromDiscord<Elegantbeef> I'm a game developer primarily so that's my main focus
23:22:02FromDiscord<ambient> Not sure is --gc:arc is actualy doing anything there
23:22:09FromDiscord<scipio> In reply to @Elegantbeef "Dont mistake my 'expertise'": the JUCE framework on C++, used for audio plugins, also has decent UI capabilities. Would that be somehow usable in NIm?
23:22:21FromDiscord<Elegantbeef> If you wrapped the C++ library likely
23:22:33FromDiscord<Nilts> In reply to @Elegantbeef "I mean why is": because nigui sucks at container traversal and because of nim's type system looping does not and will not ever work
23:22:50FromDiscord<Nilts> (edit) "In reply to @Elegantbeef "I mean why is": because nigui sucks at container traversal and because of nim's type system looping does not and will not ever work ... " added "(in this cse)"
23:22:55FromDiscord<Nilts> (edit) "cse)" => "case)"
23:22:57FromDiscord<Elegantbeef> I dont even know what you mean
23:23:06FromDiscord<Elegantbeef> It being a proc is identical to it being a template except is more proper
23:23:43FromDiscord<Nilts> In reply to @Elegantbeef "It being a proc": i thought one was compile-time and one was not. Was i mistaken
23:23:56FromDiscord<Elegantbeef> templates are code subsitution
23:24:06FromDiscord<Elegantbeef> You're still making a closure procedure regardless
23:25:45FromDiscord<pyolyokh> In reply to @ambient "Not sure is --gc:arc": there's no allocation, but arc would let you use `=destroy` and the like with new types that you come up with
23:25:54FromDiscord<pyolyokh> (edit) "allocation," => "allocation in that code,"
23:25:59FromDiscord<Elegantbeef> There is generally no reason to do `--gc:none`
23:26:42FromDiscord<Elegantbeef> There is no overhead for using arc without using a GC'd type, it allows you to use string/ref and you can as pyolyokh pointed out use hooks
23:27:20FromDiscord<Phil> I'm getting a weird runtime error that an import from the openssl bindings is failing, I'm not quite sure as to why
23:27:35FromDiscord<Phil> One sec
23:28:25FromDiscord<Phil> sent a code paste, see https://paste.rs/I0R
23:29:44FromDiscord<pyolyokh> `could not import: EVP_MD_size`↵yeah, that doesn't exist
23:29:55FromDiscord<Phil> But.... one sec
23:30:20FromDiscord<pyolyokh> ah wait, I checked for that wrong
23:30:22FromDiscord<Phil> It has in the past
23:30:30FromDiscord<Phil> That code compiles and works, or worked in the past
23:30:32FromDiscord<pyolyokh> `proc EVP_MD_size(md: EVP_MD): cint {.lcrypto.}` is indeed there in devel
23:30:35FromDiscord<Phil> I just copy pasted it into a benchy example
23:30:56FromDiscord<Phil> Oh yeah, I'm currently on 1.9.1
23:31:11FromDiscord<Phil> And I think the code originally was developed under 1.7 something
23:31:43FromDiscord<pyolyokh> 1.6.10 has got it. You can confirm by grepping for it if it's there or not
23:32:39FromDiscord<Phil> grep is one of those tools I never learned to deal with. I'm decent generally with the terminal, but I just never learned grep or more complex bash scripting. I basically use sed like once a year for a task I can't do otherwise
23:37:00FromDiscord<Phil> Also not sure where the openssl binding file is to check it out
23:37:03FromDiscord<Phil> (edit) "Also not sure where the openssl binding file is to check it out ... " added "with grep"
23:40:14*ltriant quit (Ping timeout: 268 seconds)
23:45:16FromDiscord<pyolyokh> it's openssl.nim that you're importing from
