00:06:48FromDiscord<ajusa> hm, maybe? I feel like tb.clear() would be mentioned then in the examples. And it still seems pretty wasteful to have run all the code I would have to redraw the entire screen every time there is any user input...

00:54:26FromDiscord<ShadowElf37> ah `static[int]` 🤦‍♂️
00:54:36FromDiscord<ShadowElf37> the error message really ought to be more helpful
00:55:43FromDiscord<dk> it's an actual internal error, not a message
00:55:50FromDiscord<InventorMatt> Make it a static int
00:56:19FromDiscord<konsumlamm> you should make a bug report though, internal errors shouldn't happen
00:56:34FromDiscord<dk> I'm surprised it crashes even with unspecified N (`Vector[N] = object`)
00:56:54FromDiscord<Rika> In reply to @dk "it's an actual internal": except usually it says `internal error` in the exception if it is, prolly a missed case in this case
00:57:09FromDiscord<Rika> unspecified N does not infer static i believe
00:58:06FromDiscord<ShadowElf37> i think its not bad that it doesnt infer static, but the fact that there's no helpful error is bad i think
00:58:43FromDiscord<Rika> https://nim-lang.org/docs/algorithm.html#binarySearch%2CopenArray%5BT%5D%2CK%2Cproc%28T%2CK%29 this was a very confusing proc, because "binary search" implies that the sequence must be sorted, but apparently it can do that even when the data is not sorted?
00:59:17FromDiscord<Rika> might be better to rename it?
00:59:28FromDiscord<konsumlamm> In reply to @ShadowElf37 "i think its not": again, it's an internal assertion failure, not a normal error message
00:59:52FromDiscord<Rika> In reply to @konsumlamm "again, it's an internal": and they know that, hence the "no" in "no helpful error"
01:00:25FromDiscord<konsumlamm> In reply to @Rika "https://nim-lang.org/docs/algorithm.html#binarySear": actually, it assumes that the seq is sorted...
01:00:26FromDiscord<Rika> its an uncaught edge case
01:00:31FromDiscord<konsumlamm> :P
01:00:37FromDiscord<konsumlamm> i fixed the example on devel
01:00:38FromDiscord<Rika> `assert binarySearch(["a", "b", "d", "c"], "d", system.cmp[string]) == 2`?
01:00:44FromDiscord<Rika> what the fuck then lmao
01:00:52FromDiscord<konsumlamm> that is just an edge case where it happens to work correctly
01:01:29FromDiscord<Rika> what do i use to search if its unsorted then? save for "implement it yourself" of course
01:01:34FromDiscord<konsumlamm> In reply to @Rika "and they know that,": i mean, it should be obvious that an internal error is bad, but whatever
01:02:00FromDiscord<konsumlamm> linear search
01:02:03FromDiscord<ShadowElf37> yeah but i, as the user of the language, am not going into the compiler code to fix the assertion lol

01:33:24FromDiscord<treeform> No sorry, we don't do complex resampling yet. Just the basic one.
01:33:32FromDiscord<Rika> aya okay
01:33:36FromDiscord<guzba> (it is smooth though not blocky)
01:34:06FromDiscord<Rika> well ig yalls mainly focusing on vector

01:34:38FromDiscord<Rika> ah, i am speaking in difficult english again
01:35:52FromDiscord<treeform> we basically do mip map linear right now, its good enough for now, but it will get better.
01:36:20FromDiscord<Rika> its good enough for vector yeah but if i'm rescaling something thats already raster... 😛
01:37:37FromDiscord<treeform> what lib do you use?
01:38:05FromDiscord<Rika> i think it was imageman, and i patched in lanczos myself

03:15:01FromDiscord<ajusa> jk turns out I should google for an issue before I ask for help, it is `std/exitprocs`
03:15:29FromDiscord<ajusa> Original issue still happens, doing `addExitProc(resetAttributes)`
03:15:34FromDiscord<Rika> yeah there should be an indication when you have to prefix with std or not
03:15:53FromDiscord<Rika> are you sure your terminal is not mishandling?

04:51:16FromDiscord<ajusa> Can someone help me figure out object inheritance here? https://play.nim-lang.org/#ix=2QTq↵I spent around 15 minutes searching around to see if I could find anything online for this. Basically, inheritance works as expected, but once I wrap a class in a seq it doesn't work.
04:57:05FromDiscord<Rika> In reply to @ElegantBeef "Not much benefit to": ~~just as much benefit as asking for a c compiler that goes straight to machine code than asm~~
05:03:14FromDiscord<ElegantBeef> @ajusa https://play.nim-lang.org/#ix=2QTt
05:03:34FromDiscord<ElegantBeef> You need to convert the first element to the type you want the seq to be else it takes whatever is there
05:09:36FromDiscord<ajusa> In reply to @ElegantBeef "You need to convert": Thank you so much, I understand how that works now!
05:10:01FromDiscord<ElegantBeef> The real question is always do you need inheritance or can you just use variants 😛
05:11:35FromDiscord<ajusa> In the case that I am trying to fill, I think inheritance makes since. It is a UI library that allows the user to specify a subtype of the base UI class, so that they can create `Car` and have it be compatible with all of the internal UI code.
05:15:10FromDiscord<ElegantBeef> Ah yea Nimx does something similar with inheritance 😄
05:16:34FromDiscord<ajusa> Thanks for the tip! I see that they have `Checkbox = ref object of Button` which is very similar to the idea I was trying to implement. This'll be a useful reference

11:15:10PMunchThat zipping thing reminds me of an old trick to hide things
11:15:49PMunchCreate a zip file, then grab a jpg image, concatenate the zip file on the end of the jpg image et voila
11:17:00PMunchImage viewers typically don't have a problem just showing the image, but there are only certain zip applications that actually follow the spec and read it as a valid zip file.

14:12:12FromDiscord<mratsim> In reply to @zetashift "Huh, I googled my": I don't remember this error
14:12:43FromDiscord<mratsim> that's probably one of the most confusing error message in Nim
14:14:11*enneman__ quit (Quit: Leaving)
14:18:04FromDiscord<Araq> the real problem is that nobody knows what a .partial object is, I think
14:18:27FromDiscord<Araq> (well, ok, I do know, but I doubt it ever made it into the manual)
14:19:51FromDiscord<Araq> .partial objects and .liftlocals were designed to work together
14:20:16FromDiscord<Araq> and are the building blocks for "closures via macros"
14:21:13FromDiscord<Araq> it still seems like a good feature except for the lack of polish
14:21:54FromDiscord<zetashift> Yea I didn't get what a partial object was either, my fault was `var foo.bar = "blabla"` but it should have been just `foo.bar = "blabla"` silly mistake of mine but that error got me all confused
14:22:08FromDiscord<mratsim> you will have to explain because when i read partial I think about the object slicing error.
14:23:07FromDiscord<Araq> `var foo.bar = "x"` means "add a field of type string named 'bar' to the 'foo's object type"
14:23:24FromDiscord<Araq> "and then set its value to "x""
14:23:59FromDiscord<Araq> for this foo's object type must have been marked as `.partial`
14:24:13FromDiscord<Araq> so that it remains "open" for field additions
14:24:14FromDiscord<zetashift> Ah yea that wasn't what I intended to do ofcourse 😩
14:24:45FromDiscord<zetashift> but explained like that the error makes 100% sense
14:25:24FromDiscord<zetashift> But my first reaction is, what am I doing implicitly and what is a .partial object?
14:25:58FromDiscord<mratsim> that's interesting, but likely would need a RFC.
14:26:09FromDiscord<Araq> agreed.
14:26:10FromDiscord<mratsim> or ome document like the destructors decoument
14:26:19FromDiscord<mratsim> (edit) "ome" => "some" | "decoument" => "document"
14:27:02FromDiscord<Araq> years later the idea still looks like a very good one
14:27:07FromDiscord<Araq> so I shall write the RFC
14:27:24FromDiscord<Kiloneie> That is interesting, level editor/game engine hot swap coding usage comes to mind.
14:28:09FromDiscord<Araq> @Kiloneie unlikely to be useful for that, the object is eventually sealed, it's still all done at compile-time
14:30:19FromDiscord<Kiloneie> Idk ive seen some nimscripter or some other module be able to do some neat things with hot swap code. One day i will get to that. I wanna make a game in Nim one day. I think PMunch??? 's pure nim graphical library will be useful.

15:53:54FromDiscord<konsumlamm> and why do you expect that to work?
15:54:13FromDiscord<carpal> because inherit works so
15:54:17FromDiscord<carpal> in c# it works lol
15:54:24FromDiscord<konsumlamm> it shouldn't

15:55:53FromDiscord<carpal> https://forum.nim-lang.org/t/3100
15:56:05FromDiscord<konsumlamm> you need to make an implementation for `GameObject`
15:56:15FromDiscord<carpal> I based my compiler all on inherit
15:56:17FromDiscord<konsumlamm> that works for any `GameObject`
15:56:32FromDiscord<konsumlamm> and then you can have a specialize implementation for `ColoredSquare`
15:57:50FromDiscord<carpal> In reply to @konsumlamm "you need to make": what are you talking about?

16:03:00FromDiscord<konsumlamm> i'm not sure what the `{.base.}` is for, but i would assume that it's only needed for `method drawEntity(entity: GameItem)`, i.e. only for the base case

16:53:10PMunchBeats no libraries
16:53:43PMunchWell, I shouldn't complain too much. I am using some Nim at work
16:56:44FromDiscord<carpal> is there a way to make a ref object of rootobj to inherit from multiple ref objects?
16:57:03FromDiscord<carpal> something like this https://media.discordapp.net/attachments/371759389889003532/814903867099316234/unknown.png
16:57:42FromDiscord<Yardanico> multiple inheritance is not supported
16:57:48FromDiscord<Yardanico> and in that code example you don't need "RootObj" anyway
16:58:34FromDiscord<carpal> gameitem is inherited from other objects
16:58:36FromDiscord<carpal> so yes
16:58:41FromDiscord<carpal> (edit) "from other" => "byother"
16:58:45FromDiscord<carpal> (edit) "byother" => "by other"
16:59:33PMunchNo
17:00:13PMunchDimension inherits from RootObj then GameItem can inherit from Dimension and that can be inherited by other objects just fine

17:10:41FromDiscord<konsumlamm> and yet it throws an exception
17:11:15FromDiscord<treeform> yeah don't use threads or async together async is not thread safe
17:11:23FromDiscord<Yardanico> you can do it with manual code
17:11:25FromDiscord<Yardanico> like httpbeast
17:11:36FromDiscord<treeform> you are using ptr to pass websockets around, I don't think that works either
17:12:08FromDiscord<hamidb80> In reply to @hamidb80 "": this code doesn't word too
17:12:16FromDiscord<hamidb80> (edit) "word" => "work"
17:12:35FromDiscord<treeform> The way httpbeast is kind of "cheating" in a good way. It just starts an async reactor per thread. Like as if you just started multiple programs.
17:13:25FromDiscord<treeform> yeah async/waitFor can't work instead {.thread.}
17:13:42FromDiscord<treeform> (edit) "instead" => "inside"
17:13:46FromDiscord<hamidb80> thanks
17:14:03FromDiscord<treeform> You could do what httpbeast, but its way complex
17:14:31FromDiscord<treeform> you are better off running multiple nodes and have them communicate via DB like postgress or redis.
17:14:39FromDiscord<treeform> then you are multi machine too, not just multi thread
17:14:43FromDiscord<treeform> (that is what I do at work)
17:18:17FromDiscord<treeform> redis is async and has channels you can communicate between your nodes that way
17:18:43FromDiscord<treeform> instead of sending stuff to a nim channel and reading from a nim channel you do that with redis.

17:46:01FromDiscord<hamidb80> parallelism is more complex than i thougth
18:09:30FromDiscord<dom96> you barely ever need parallelism
18:09:43FromDiscord<mratsim> depends on what you do
18:10:22FromDiscord<dom96> well yes, but the cases where it is necessary are far less common than some think
18:10:34FromDiscord<dom96> and most people think they need parallelism when they don't
18:13:51FromDiscord<mratsim> You can't just say that, if you are just doing pipes copying data everywhere, sure. If you actually transform the data you might have CPU bound workflow.
18:14:24FromDiscord<mratsim> Even for network, encrypting/decrypting is something that can be tawing with lots of connections.
18:14:41FromDiscord<mratsim> but parallelism != concurrency != multithreading.
18:14:55FromDiscord<mratsim> and IO tasks != CPU tasks
18:14:59FromDiscord<mratsim> that is true.

19:07:34FromDiscord<Araq> `varargs` are a bit broken because we the type conversion rules are defective and predate macros.unpackVarargs
19:08:14FromDiscord<Araq> to make matters worse we don't have an RFC how to fix them (but it likely involves simply removing code from the compiler)

19:46:00FromDiscord<Yardanico> sent a code paste, see https://play.nim-lang.org/#ix=2QYD
19:46:02FromDiscord<carpal> brooo
19:46:12FromDiscord<carpal> you didn't understand what I need
19:46:22FromDiscord<Yardanico> "has anyone some idea about how to convert nanoseconds to seconds and nanoseconds?"
19:46:26FromDiscord<Yardanico> you already get nanoseconds for free
19:46:31FromDiscord<Yardanico> argh
19:46:32FromDiscord<Yardanico> look
19:46:34FromDiscord<Yardanico> its simple math still
19:46:45FromDiscord<carpal> In reply to @Yardanico ""has anyone some idea": nanoseconds -> seconds.nanoseconds
19:47:28FromDiscord<carpal> nanoseconds = 100001↵result I want = 1.0001 (seconds.nanoseconds)
19:47:29FromDiscord<hamidb80> In reply to @carpal "nanoseconds -> seconds.nanoseconds": what's that
19:47:52FromDiscord<Solitude> ????
19:47:58FromDiscord<hamidb80> In reply to @carpal "nanoseconds = 100001 result": that's not nanoseconds
19:48:16FromDiscord<Yardanico> @carpal explain what do you need those for
19:48:20FromDiscord<Yardanico> it seems like an x y problem
19:48:30FromDiscord<carpal> I need the a float reppresenting the seconds dot milli, micro, nanos
19:48:37FromDiscord<Yardanico> you already get one
19:48:38FromDiscord<Yardanico> for free
19:48:47FromDiscord<Yardanico> it's in the seconds already
19:48:52FromDiscord<Yardanico> since it's a FLOAT
19:48:53FromDiscord<carpal> yes...
19:48:55FromDiscord<Yardanico> yes
19:48:59FromDiscord<Yardanico> do you need one float or multiple floats?
19:49:23FromDiscord<hamidb80> > I need the a float reppresenting the seconds dot milli, micro, nanos
19:49:37FromDiscord<carpal> but I need a float where the part before the comma is the second and after the comma the milliseconds
19:49:51FromDiscord<Yardanico> but why
19:49:53FromDiscord<Yardanico> i mean
19:49:56FromDiscord<Yardanico> it already is like that by default
19:50:05FromDiscord<Solitude> In reply to @carpal "but I need a": thats not how floats work
19:50:07FromDiscord<Yardanico> let seconds = 1.0101 # 1 second and 101 ms
19:50:19FromDiscord<Yardanico> sorry 10 ms
19:50:25FromDiscord<Yardanico> 10.1 ms
19:50:27FromDiscord<carpal> In reply to @Yardanico "let seconds = 1.0101": yea ok
19:50:30FromDiscord<carpal> I need this
19:50:33FromDiscord<Yardanico> ?????????????
19:50:51FromDiscord<Yardanico> I honestly have no clue what are you trying to get :P
19:50:55FromDiscord<hamidb80> In reply to @carpal "I need this": you need what
19:50:55FromDiscord<carpal> like delta time
19:51:10FromDiscord<Yardanico> let deltaTime = newSeconds - oldSeconds
19:51:25FromDiscord<carpal> but it is not accurate
19:51:36FromDiscord<carpal> seconds are int
19:51:37FromDiscord<Yardanico> for accurate representation use timeinterval from times
19:51:38FromDiscord<Solitude> let deltaTime = newTime - oldTime
19:51:47FromDiscord<carpal> yes...
19:51:51FromDiscord<Yardanico> use timeinternval
19:51:54FromDiscord<carpal> https://media.discordapp.net/attachments/371759389889003532/814947868573171762/unknown.png
19:51:58FromDiscord<carpal> I already did this
19:52:12FromDiscord<Solitude> so, whats the problem?
19:52:31FromDiscord<hamidb80> i can't even guess your problem
19:52:51FromDiscord<Yardanico> sent a code paste, see https://play.nim-lang.org/#ix=2QYH
19:52:55FromDiscord<Yardanico> deltaTime is a TimeInterval object then
19:52:57FromDiscord<Yardanico> https://nim-lang.org/docs/times.html#TimeInterval
19:53:13FromDiscord<Yardanico> in your case you don't need to do `initTimeInterval` just save oldTime and newTime, and calculate `deltaTime` as the difference between the two
19:53:44FromDiscord<carpal> In reply to @Yardanico "<@!699146708466008115> ```nim import": why + 3 seconds 5 nanos and 15 millis?
19:53:50FromDiscord<Yardanico> JUST TO SHOW HOW IT WORKS
19:53:54FromDiscord<Yardanico> In reply to @Yardanico "in your case you": ^
19:54:04FromDiscord<carpal> yes... I just tried it
19:54:11FromDiscord<carpal> but it is not what I nedd
19:54:12FromDiscord<carpal> (edit) "nedd" => "nee"
19:54:13FromDiscord<carpal> (edit) "nee" => "need"
19:54:16FromDiscord<Yardanico> but what do you actually need
19:54:23FromDiscord<carpal> do you know how delta time works?
19:54:24FromDiscord<Yardanico> 3 people failed to understand the actual problem you're facing
19:54:31FromDiscord<Solitude> In reply to @carpal "do you know how": do you?
19:54:36FromDiscord<carpal> ahha
19:54:53FromDiscord<Yardanico> @carpal delta time is Δtime = newTime - oldTime
19:54:56FromDiscord<Yardanico> that's why it's DELTA
19:55:02FromDiscord<Yardanico> "difference" (-) between two values
19:55:21FromDiscord<carpal> yes okay, if it is so simple show me in playground echo delta

19:55:42FromDiscord<Yardanico> sent a code paste, see https://paste.rs/toB
19:55:43FromDiscord<Yardanico> here you go, `deltaTime` is actually delta time
19:56:46FromDiscord<carpal> this is not a float delta time https://media.discordapp.net/attachments/371759389889003532/814949096598667284/unknown.png
19:57:04FromDiscord<Yardanico> ok, I give up, maybe others will be able to help you but not me, I have no clue about your issue :)
19:57:06FromDiscord<carpal> void onupdate(float delta) {↵↵}

20:00:20FromDiscord<hamidb80> In reply to @carpal "void onupdate(float delta) {": turn it into float
20:00:27FromDiscord<carpal> ahhah duration?

20:03:16FromDiscord<hamidb80> i really dont know what you are trying to do
20:03:38FromDiscord<hamidb80> but if you wanna convert `Duration` to `float` that works

20:26:14JustASlackerhello peoples of nim
20:26:35asdflkjhi
20:26:38JustASlackerdo I have to declare each and every field of an object with * to export it?
20:26:43*JustASlacker waves
20:26:54FromDiscord<Yardanico> yes, you do
20:26:59JustASlackerbummer
20:27:01FromDiscord<Yardanico> because usually you don't want to export a lot of fields
20:27:35*asdflkj wonders if CTCP actions are bridged to Discord and Gitter
20:27:39JustASlackeris that so? I just declared an object Certificate, which just holds data about x509 certs
20:27:56JustASlackerand pretty much any field should be accessible
20:28:02FromDiscord<Yardanico> @asdflkj without the special me stuff, but they are
20:28:04FromDiscord<Yardanico> to discord at least
20:28:32JustASlackerisnt gitter matrix now
20:28:37FromDiscord<Yardanico> not really
20:28:59asdflkjhttps://matrix.org/blog/2020/12/07/gitter-now-speaks-matrix
20:29:02FromDiscord<Yardanico> like you can connect to Gitter rooms from Matrix, but you still can't bridge Gitter as if it would just been Matrix
20:29:10FromDiscord<Yardanico> that's why we're still using that FromGitter bridge
20:29:34asdflkjgitter is going to become matrix, but only when matrix has all of gitter's features (IIUC)
20:31:05*superbia quit (Quit: WeeChat 3.0)
20:33:45haxscramperHow I can create `ref seq[T]` using `newSeq[T]()`? I know that `ref seq` is really strange, but I think I have specific reasons to use that (or `ptr` which is probably worse overall in my case).
20:35:22JustASlackerwell I kinda like gitte but matrix looks nice
20:35:23FromDiscord<Yardanico> var myRefSeq: ref seq[int]; myRefSeq[] = newSeq[int]()
20:35:37FromDiscord<Yardanico> ah actually wait
20:35:54FromDiscord<Yardanico> var myRefSeq = new(seq[int])
20:35:55FromDiscord<Yardanico> just this is enough
20:36:25FromDiscord<Yardanico> !eval var myRefSeq = new(seq[int]); myRefSeq[].add(5); echo myRefSeq[]
20:36:27NimBot@[5]
20:36:36haxscramperNo your first answer was perfect, I actually need `newSeq` with number of elements
20:36:47haxscramperThanks, I completely forgot about assign to dereference
20:36:59FromDiscord<Yardanico> well my first example is invalid because you need to allocate it first anyway
20:37:08FromDiscord<Yardanico> so if you want with number of elements its
20:37:13FromDiscord<Yardanico> var myRefSeq = new(seq[int]); myRefSeq[] = newSeq[int]()
20:37:50FromDiscord<Yardanico> Nim does automatic dereference for dot access but not for seqs :)
20:38:18FromDiscord<Yardanico> err, actually no, it's because add is a proc and not a field
20:38:45haxscramperAutomatic dereference for procs is experimental IIRC
20:39:01FromDiscord<Yardanico> yeah, it's behind an experimental switch
20:39:09haxscramperBut semcheck tries all overload twice, at least if I remember that part correctly
20:40:12haxscramperAh, yes `elif implicitDeref in c.features and canDeref(n):` < only with that one, so yes, only with experimental implicit deref
20:41:59FromDiscord<Yardanico> you could've just read the manual to get the same info :P
20:42:55haxscramperActually with sourcetrail it is faster
20:43:04FromDiscord<hamidb80> i don't think the problem is from using `async` in a `thread`, I think it's a problem with websocket library↵↵this code works fine. https://media.discordapp.net/attachments/371759389889003532/814960743589216326/unknown.png
20:43:56FromDiscord<konsumlamm> just because async in thread works fine sometimes, doesn't mean it works together in general
20:44:11haxscramperThis is basically Ctrl+F, but since I remember this is a `semOverloadedCall`, it took me a couple secons overall. But I don't have experimental manual link quickly and have to google this each time, so
20:44:15FromDiscord<hamidb80> In reply to @hamidb80 "": .
20:44:26*Vladar joined #nim
20:44:49FromDiscord<Yardanico> @hamidb80 as people said multiple times, async doesn't actually work with threads the way you want it to work
20:44:57FromDiscord<Yardanico> you can't await a future from another thread for example
20:45:12FromDiscord<Yardanico> since the async dispatcher is thread local
20:47:00*ForumUpdaterBot quit (Remote host closed the connection)
20:47:12*ForumUpdaterBot joined #nim
20:48:02FromDiscord<treeform> I wish threads+async in Nim was easier to use.
20:48:21FromDiscord<treeform> Even just threads without async easier to use...
20:48:39FromDiscord<XxDiCaprioxX> hey, does anyone here by chance know what a DiscordFile is? if not that's also fine
20:49:01FromDiscord<treeform> When you send a file through the Discord app?
20:49:26FromDiscord<XxDiCaprioxX> but is the type the same for all languages or like a nim exclusive thing?
20:49:28FromDiscord<Yardanico> @XxDiCaprioxX maybe you can provide more context?
20:49:36FromDiscord<Yardanico> is that about dimscord?
20:49:54FromDiscord<XxDiCaprioxX> In reply to @Yardanico "is that about dimscord?": if I reply with yes, will you tell me to ask in the dimscord dc server?
20:50:29FromDiscord<XxDiCaprioxX> because yes it is
20:50:30FromDiscord<Solitude> In reply to @XxDiCaprioxX "if I reply with": read the docs
20:50:47FromDiscord<Yardanico> @XxDiCaprioxX if I were you I'd just check dimscord src to see how it uses DiscordFile
20:50:59FromDiscord<hamidb80> In reply to @treeform "I wish threads+async in": could you implement something like `tryReceivePacket` like channels?
20:51:01FromDiscord<XxDiCaprioxX> I read the docs but I must have somehow skipped over it by accident cuz I was unable to find it
20:51:12FromDiscord<XxDiCaprioxX> but I'll just have a look again
20:51:21FromDiscord<Yardanico> and to answer the question - yes, that's dimscord specific
20:51:22FromDiscord<Solitude> by docs i mean source, and by read i mean ctrl+f
20:51:30FromDiscord<Yardanico> it's an abstraction over discord's executewebhook

20:51:55FromDiscord<XxDiCaprioxX> In reply to @Yardanico "and to answer the": okay thanks
20:52:10FromDiscord<XxDiCaprioxX> In reply to @Solitude "by docs i mean": yeah I know that, prolly skipped a file by accident before
20:52:48FromDiscord<XxDiCaprioxX> what is a `refObject`?
20:52:57*krux02 joined #nim
20:53:08FromDiscord<Yardanico> `ref object` is a heap-allocated object
20:53:19FromDiscord<Yardanico> have you read nim's tutorials and nim basics?
20:53:26FromDiscord<XxDiCaprioxX> yes and no
20:53:44FromDiscord<Yardanico> https://nim-lang.org/docs/tut1.html#advanced-types-reference-and-pointer-types
20:53:56FromDiscord<XxDiCaprioxX> I know some stuff but idk what heap-allocated object means for example. anyways I assume I dont need to know it to make the application work
20:54:52FromDiscord<XxDiCaprioxX> hmmm, discord file has `name, body: string` as attributes. assuming body is the content, do I need some kind of conversion to turn my file into a string?

22:52:42*Vladar quit (Quit: Leaving)
22:54:08liblq-devmatrix is free and open-source and discord is proprietary
22:54:12liblq-devis one way to put it
22:55:10FromDiscord<バロザード> do they have the same features
22:55:19nxnl[m]matrix is also federated and a protocol implemented by several clients and at least two server
22:57:05FromDiscord<バロザード> so if discord shuts down tomorrow, everyone could move over to matrix clients and nothing much would change?
22:57:08FromDiscord<ElegantBeef> Element is mostly on feature parity as discord
22:57:27FromDiscord<ElegantBeef> The major issue is just that it lacks a channelled voip solution intergrated
22:57:47FromDiscord<バロザード> by that you mean?
22:58:37liblq-devgood voice chat.
22:58:48FromDiscord<ElegantBeef> I mean it doesnt have anything like mumble or discord voip intergrated
22:58:55liblq-devit also lacks the discord notion of "servers"
22:59:06liblq-devthere are communities but they're a bit half-baked
22:59:16liblq-devand they're working on something new
22:59:31FromDiscord<バロザード> aw man
22:59:39FromDiscord<バロザード> voice chat is what makes discord discord
23:00:35*xet7 quit (Remote host closed the connection)
23:00:59FromDiscord<ElegantBeef> Well element has voip but it's currently using jitsi for group calls so it's very meh
23:02:51liblq-devyeah
23:03:15liblq-devthe experience can be summarized as "meh" compared to discord, but bear in mind that discord has a commercial company working behind it.
23:03:51liblq-devalso, the arguably worse experience prevents you from peeking at your chat client every 8 seconds, so that's a win for me.
