00:00:18FromDiscord<Elegantbeef> I'm just a funky chatgpt
00:01:45FromDiscord<Ayy Lmao> That's what c2nim was saying but I was hoping there was a prettier way.
00:01:56FromDiscord<Ayy Lmao> `ClapNsView = ClapNsView` 👀
00:02:02FromDiscord<Elegantbeef> That was me being dumb
00:02:10FromDiscord<Elegantbeef> Nim doesnt have anonymous unions(for good reason i'd argue)
00:02:50FromDiscord<Ayy Lmao> Do you have to do `window.union.win32` to access it?
00:02:56FromDiscord<Elegantbeef> Yes
00:03:03FromDiscord<Elegantbeef> If you do not want that write accessors
00:03:14FromDiscord<Ayy Lmao> I guess that could be done
00:03:34*pbsds joined #nim
00:04:25FromDiscord<Ayy Lmao> I noticed you didn't put `bycopy` on anything but c2nim puts it on everything. When is it important to put it?
00:04:51FromDiscord<Elegantbeef> Does the API pass the value with a pointer always or does it pass it by vallue
00:05:26FromDiscord<Ayy Lmao> Most things are passed by pointer I think
00:05:38FromDiscord<Elegantbeef> If you're interoping with C you need to disable Nim's optimisation if it's a large object
00:05:58FromDiscord<Elegantbeef> by default Nim decides on how to pass an object by it's size, you can override this by using `{.bycopy.}`
00:06:13FromDiscord<Elegantbeef> Adding it mimics the way C does things
00:06:23FromDiscord<Ayy Lmao> That makes sense

00:56:24FromDiscord<lauvrens> Yeah the current error is Index defect just for testing
00:56:42FromDiscord<Elegantbeef> Well defects are not supposed to be caught is my point
00:56:54FromDiscord<lauvrens> Oh
00:56:59FromDiscord<Elegantbeef> But anyway you cannot really do what you want
00:58:03FromDiscord<Elegantbeef> reading from the stdin is blocking so while doing `readLine` it waits for a `\n` also known as user input
00:59:27FromDiscord<lauvrens> damn ok this is tough

01:01:28FromDiscord<Elegantbeef> What's an invalid line?
01:01:46FromDiscord<lauvrens> some uncaught error that causes the program to terminate
01:02:37FromDiscord<Elegantbeef> I'm a bit confused how that matters
01:03:18FromDiscord<Elegantbeef> It's not like shells backread the stdin and use characters that were not read
01:03:19FromDiscord<that_dude> Is this a parsing issue or an invalid character issue?
01:03:34FromDiscord<Elegantbeef> Yea like what are you doing that this is a concern
01:12:50FromDiscord<lauvrens> its just some weird behaviour i wanted to prevent, its not important. just wanted to see if there was a way to exit it 'cleanly' if that makes sense
01:16:35FromDiscord<that_dude> There's many types of weird behavior ya know? Can't you give an example instead of being so round about what an issue looks like? If your input can be delimited by newlines you can just do that and stop parsing and exit on something that fails to parse

01:30:02FromDiscord<lauvrens> i wanted to handle the exception so that it reads all the input before leaving the program.↵↵the input being read into the terminal after the program ends _is_ the wierd behaviour to me. again its not important i just wanted to see if it was possible https://media.discordapp.net/attachments/371759389889003532/1097333111903223918/X4kHZ4c.png
01:30:52FromDiscord<Elegantbeef> Why is the program crashing though
01:30:52FromDiscord<Elegantbeef> You have an index defect, solve that issue then you will not have a crash
01:31:10FromDiscord<Elegantbeef> Do not compile a release build to actually get a usable stack trace
01:35:53FromDiscord<Raynei486> In reply to @Elegantbeef "Seems it's for skipping": What did lifecore biomedical do?? https://media.discordapp.net/attachments/371759389889003532/1097334587736215552/image.png
01:35:55FromDiscord<lauvrens> yeah ur right im just stubborn and wanted to implement it in general.
01:36:26FromDiscord<Raynei486> okay so CRLF is fancy line breaks
01:44:13FromDiscord<that_dude> Yeah iirc linux just uses \n and knows what you want while windows uses \cr to return the cursor to the left and \lf to go down

06:05:21FromDiscord<Elegantbeef> It tells you where
06:05:42FromDiscord<lauvrens> the number is increasing, it never reaches 1
06:07:20FromDiscord<that_dude> Doesn't it also give this error when the while loop runs for too long?
06:07:41FromDiscord<that_dude> I thought that happened to me before
06:07:48FromDiscord<Arvin❓> In reply to @lauvrens "the number is increasing,": so a number that is steadily increasing will lead to overflow? or does it have something to do with the loop or something? What topic should i learn to understand this problem
06:07:54FromDiscord<Elegantbeef> That's stack overflow and it's not while loop
06:07:55FromDiscord<Arvin❓> (edit) "problem" => "problem?"
06:08:07FromDiscord<Elegantbeef> Overflow i when you have a number outside of a the range of the integer
06:08:15FromDiscord<Elegantbeef> Go read the wikipedia about it
06:08:33FromDiscord<Elegantbeef> you can have a max value of 2^63 - 1 inside an `int`
06:08:33FromDiscord<lauvrens> In reply to @Arvin❓ "so a number that": im pretty sure it has to do with the number being larger than what the variable can handle

06:10:40FromDiscord<Elegantbeef> An `int` in Nim is a signed platform dependant integer that is commonly 64bit

06:54:37FromDiscord<Rika> beef can you explain to me what the hook method is for making externally extensible modules because i also need my data types to store state and i dont know how i'd do that without going through generics or variants
06:55:30FromDiscord<Elegantbeef> hook method?
06:55:47FromDiscord<Rika> idk i hear about hooks sometimes when people talk about the newer json libraries
06:56:07FromDiscord<Elegantbeef> Oh ok so generic interfaces
06:56:21FromDiscord<Rika> but i'd like these extensions to be per object and not per type
06:56:23FromDiscord<Rika> well
06:56:36FromDiscord<Rika> per object and per type would apply ig if i use generics
06:56:52FromDiscord<Rika> for context i'm working on that progress bar library again
06:56:56FromDiscord<Elegantbeef> Well you'd just make the per object procedure inside the per type
06:57:10FromDiscord<Rika> yes but then what about state
06:57:20FromDiscord<Rika> generics would be annoying
06:57:39FromDiscord<Elegantbeef> What type of state is required?
06:58:13FromDiscord<Rika> lets say like statistics on the progress bar OR messages displayed or whatever else
06:58:45*cm quit (Ping timeout: 240 seconds)
07:00:22FromDiscord<Elegantbeef> Yea I'd go with generic interfaces that can override default behaviour
07:00:36FromDiscord<Elegantbeef> I do not know what the blocker really is, I need a code example of the problem
07:02:14FromDiscord<Rika> well, i have a data type that manages multiple progress bars (another data type) and i would like to be able to store different styles of these progress bars (lets say one that doesnt use statistics data and one that does) in that manager data type, and lets say i cannot say what these bars' inner generic types are beforehand
07:03:22FromDiscord<Elegantbeef> Ah so you have runtime polymorphism really
07:03:43FromDiscord<Rika> eugh
07:04:12FromDiscord<Elegantbeef> You have a top level object that stores sub objects which can have different attributes
07:04:31FromDiscord<Rika> :nyoron:
07:04:32FromDiscord<Elegantbeef> That sounds like either using pointer procedures or inheritance
07:08:20FromDiscord<Elegantbeef> sent a code paste, see https://paste.rs/7Yt
07:08:32FromDiscord<Elegantbeef> But yea everything isnt going to be pretty
07:08:45FromDiscord<Rika> the progress needs to store state across its function call
07:08:54FromDiscord<Elegantbeef> progress is a closure procedure
07:09:04FromDiscord<Elegantbeef> State is stored inside the closure instead of on the object
07:09:21FromDiscord<Rika> hmm i guess thats one way but it feels inelegant

09:17:50Amun-RaI can see why strictDefs are experimental, https://play.nim-lang.org/#ix=4tCj
09:19:29FromDiscord<Elegantbeef> That's working as intended afaik
09:19:54FromDiscord<Elegantbeef> https://play.nim-lang.org/#ix=4tCk
09:20:41PMunchThat shouldn't be needed though..
09:20:49FromDiscord<Elegantbeef> Strict defs
09:20:54PMunchStill
09:21:13PMunchWhat would it be apart from `default`?
09:21:41FromDiscord<Elegantbeef> It would require quite a bit of compiler logic to see that you iterate the entire range of the array and intialize every index
09:22:10PMunchOh wait, that is the point of strictDefs?
09:22:16FromDiscord<Elegantbeef> Yess
09:22:26PMunchWhy would that be useful?
09:22:29FromDiscord<Elegantbeef> The point of strictdef is to ensure you intialize a variable explicitly
09:22:51FromDiscord<Elegantbeef> Araq liked the idea of definite assignment
09:23:23FromDiscord<Elegantbeef> `out` was also implemented
09:23:33PMunchBut everything is initialized as `default` anyways? I'm confused :P
09:23:56FromDiscord<Elegantbeef> Do not look at me
09:24:07FromDiscord<Elegantbeef> I find strictdefs quite questionable when `requiresInit` exists
09:24:18PMunch`out` is fine though
09:25:01PMunchThat's a pretty cool feature
09:25:32FromDiscord<Elegantbeef> out or requires?
09:25:41PMunchBoth TBH
09:27:10FromDiscord<Elegantbeef> The odd thing is that strictdefs was added after object defaults
09:27:36FromDiscord<Elegantbeef> so like with strict defs you have to do `var a = default MyType` instead of `var a: MyType` even if you explicitly defined a default state
09:33:44FromDiscord<jmgomez> Do this looks like a CI error? https://github.com/nim-lang/Nim/pull/21628/checks?check_run_id=12795877755

10:55:44PMunchBasically Nim 2 changes
10:56:00FromDiscord<Yardanico> well, technically it's separate from nim 2, but yeah :)
10:56:16PMunchUnfortunately if you have a pkgs folder then Nim 2.0 won't see the pkgs2 folder..

10:57:28FromDiscord<System64 ~ Flandre Scarlet> Hi, is it possible to sort a seq of Point(x, y: int) by their Y value?
10:57:47PMunchYes, but if you install something with pre-2.0 Nimble then Nim won't see the post-2.0 packages

10:58:49PMunch@fabricio, yes
10:58:55FromDiscord<fabricio> thanks
10:59:16PMunchBut if you switch back to pre-2.0 then it won't see any of the packages you installed with 2.0 Nimble
10:59:16FromDiscord<ricky> In reply to @theSherwood "Leaving the advisability of": in theory
10:59:52FromDiscord<ricky> the thinking man's choice is x86 asm `bswap` tho
11:00:02PMunch@theSherwood, in general the question "can it be done in Nim" is answered with "yes"
11:00:09FromDiscord<ricky> and store the flag on the end
11:00:18FromDiscord<ricky> no need to do real-time bit shifting

11:00:55FromDiscord<ricky> a lord like @treeform would prob know
11:03:55FromDiscord<theSherwood> Am I understanding correctly that bswap swaps endianness?
11:06:47FromDiscord<theSherwood> In reply to @PMunch "<@570542675745308672>, in general the": So then the byte sequence would no longer be NaN and it would be possible to read it as bytes? Is that the idea?
11:07:20PMunchOh I have no idea what you're trying to do, I was just saying that everything is possible
11:07:43FromDiscord<theSherwood> Gotcha. I'm just trying to read NaN as a sequence of bytes.
11:08:31FromDiscord<theSherwood> But I get `SIGSEGV: Illegal storage access. (Attempt to read from nil?)` which sort of suggests to me that NaN isn't just a float?

11:12:37PMunchI'm not quite sure what the problem is: https://play.nim-lang.org/#ix=4tCz
11:15:32FromDiscord<theSherwood> Interesting. I was using `echo cast[seq[byte]](NaN)` which does not work for NaN but seems to work for other floats.
11:15:49PMunchIt shouldn't..
11:16:14PMunchA seq[byte] is a pair of size/capacity integers and a pointer to the actual data
11:16:53FromDiscord<theSherwood> So the issue is that you can't point to a literal?
11:17:10PMunchNo
11:17:32PMunchThe issue is that you try to cast a single 8 byte value into a 24 byte complex object
11:17:59PMunchIt's like calling your car a boat and being surprised when it sinks as you drive it into the lake
11:19:55PMunchIt "worked" with other numbers purely by coincidence
11:20:23FromDiscord<theSherwood> Hmm. I don't follow how it worked by coincidence
11:20:41PMunchSome cars happen to be slightly waterproof
11:21:00FromDiscord<theSherwood> haha. Okay. So just based on the value of the float?
11:21:07PMunchPretty much
11:21:18FromDiscord<djazz> pmunch: typo in article "square on" should be "square one"
11:21:42FromDiscord<theSherwood> In reply to @PMunch "Pretty much": bizarre. That's good to know. thanks for your help
11:21:55PMunchIt would read the value of the float as the size (i.e. amount of elements stored) and then grab the capacity (i.e. memory allocated) and pointer to the data from the next two numbers on the stack
11:22:21FromDiscord<theSherwood> Ohh. Okay. gotcha. that makes sense
11:22:24PMunch@djazz, thanks :)
11:22:42FromDiscord<demotomohiro> @theSherwood Maybe, `cast[array[uint8, 8]](NaN)` is what you want.
11:23:10FromDiscord<theSherwood> Yep. cheers!
11:23:20PMunchWell, what he wants is probably to do something more sane than casting floats to ints..

14:28:06FromDiscord<WabileM> Ssh2
14:32:07FromDiscord<WabileM> Using the ssh2 library, the command "echo await client.execCommand(command_on_remote_server)" return the output of the command. How do I capture this output into a string variable to allow me to parse it?
14:32:34FromDiscord<Yardanico> In reply to @WabileM "Using the ssh2 library,": uhh, I'm sorry, but have you actually read the basics of the language?
14:32:45FromDiscord<Yardanico> you just assign the output to the variable instead of echo'ing it like let myvar = <statement>
14:32:53FromDiscord<Yardanico> (edit) "<statement>" => "<expression>"
14:32:59FromDiscord<Yardanico> echo is a proc that takes an expression that returns a string and outputs it
14:34:29FromDiscord<Nilts> how do i do element.name to get a child element with name in karax without digging through children
14:34:41FromDiscord<WabileM> I use Nim for quite a number of scripts. I have tried assign the ssh output to a string variable and the compiler complains. Echo works well to display the output on the screen.
14:35:01FromDiscord<Yardanico> In reply to @WabileM "I use Nim for": can you show the error what happens when you do `let myvar = await client.execCommand(command_on_remote_server)`
14:35:04FromDiscord<Yardanico> (edit) "what" => "that"
14:35:21FromDiscord<Yardanico> if you have a specific issue, it's best to mention it instead of asking for workarounds in the chat right away without mentioning the original issue
14:38:54FromDiscord<WabileM> the specific error I get is:
14:38:56FromDiscord<WabileM> Error: type mismatch: got '(string, string, int)' for '↵var internalTmpFuture`gensym20: FutureBase = execCommand(client, command)
14:39:49FromDiscord<WabileM> I have
14:39:52FromDiscord<WabileM> var cmdOutput = ""
14:40:03FromDiscord<WabileM> cmdOutput = await client.execCommand(command)
14:40:14FromDiscord<Yardanico> yes, because that execCommand returns a tuple of 3 values, not just the string output
14:40:24FromDiscord<Yardanico> it tells you that with (string, string, int) which is a tuple with string, string and an int
14:40:47FromDiscord<Yardanico> you can see it returns 2 strings: stdout and stderr, and exitcode as the third int https://media.discordapp.net/attachments/371759389889003532/1097532112464257114/image.png

14:42:23FromDiscord<⃟⃟> is the last name "Rumpf" derived from "rump"
14:42:29FromDiscord<Yardanico> In reply to @⃟⃟ "is the last name": go to #offtopic
14:42:33FromDiscord<WabileM> thank you Yardanico. I did have a look at the definition of that procdure, but I did not interpret the return value as a tuple. I was probabbly not paying attention.

16:22:19PMunchApparently that was the issue
17:16:39FromDiscord<Oscour> Hi! Very quick question to which I'm not sure I found an answer online. I created an array of 16 bytes and would like to divide in 2 slices: one that references the 2 first elements and the second one the remaining 14 bytes. I want that if I change value in one of the slice, the change also happens in the reference array (so no data copy). Is there a simple way to do that? otherwise, I will just store the Slice objects in variables and us
17:17:26FromDiscord<Oscour> I am looking for a similar behavior to micropython's memoryviews: https://docs.micropython.org/en/v1.9.3/pyboard/reference/speed_python.html#arrays
17:29:25FromDiscord<auxym> In reply to @Oscour "Hi! Very quick question": Exoerimental atm: https://nim-lang.org/docs/manual_experimental.html#view-types
17:30:17FromDiscord<auxym> otherwise you could implement a pointer (or ref) / indices wrapper object as you suggest. note that using ptrs is unsafe and could result in use after free bugs if you are not careful.
17:40:13FromDiscord<Oscour> Thanks! I tried the views and it didn't work. Frankly I am just gonna use the indices as using a view in this case seems unecessary. I'm just trying to port a micropython library to Nim so I would have mean easier copy and pasting haha 😄

17:55:20FromDiscord<guttural666> is it smart to keep futures around for a long time, if I only need them way later in the life time of the program? I think procedure state has to be kept around for that long to be resumable, right?

23:20:00FromDiscord<Yardanico> generally if you don't want something to be evaluated multiple times in a template, you assign it to a variable that has a different name
23:20:32FromDiscord<Raynei486> will keep in mind, thanks
