00:57:54FromDiscord<Yardanico> No, you were actually able to check them, but apparently as beef said it's broken now
01:02:16FromDiscord<TryAngle> In reply to @Yardanico "No, you were actually": ah I see ok, because I checked last week or so and was wondered why I didn't find anything but this makes sense then

01:14:20FromDiscord<Alea> do you just update a package by doing nimble install? or do you need to uninstall the existing one first?
01:14:52FromDiscord<Elegantbeef> You can have multiple versions installed concurrently
01:15:29FromDiscord<Alea> is there a command to update the existing install?
01:16:18FromDiscord<Elegantbeef> nope
01:16:48FromDiscord<Alea> :BwaahSnap:
01:16:55FromDiscord<Alea> this seems like an odd thing to be missing
01:17:10FromDiscord<Elegantbeef> You dont generally need to update all your packages
01:17:20FromDiscord<Alea> I mean just updating one

01:19:11FromDiscord<TryAngle> what does↵`new result`↵do?
01:19:16FromDiscord<TryAngle> or what does new do in general?

01:19:22FromDiscord<Alea> treeform hasn't made a new boxy release :BwaahSnap:
01:19:26FromDiscord<Elegantbeef> New heap allocates the value
01:19:40FromDiscord<Elegantbeef> `new int` allocates a `ref int` and 0's it
01:19:42FromDiscord<ajusa> what's the "easiest" way to call a proc in a new thread and async wait for its answer? I know about https://github.com/yglukhov/asyncthreadpool but curious if there are other solutions.
01:20:10FromDiscord<Elegantbeef> The built in thread pool?

01:27:46FromDiscord<Alea> I assume that's because my stuff isn't on the package list right?
01:28:58FromDiscord<Alea> ah, got it?
01:36:06FromDiscord<!Patitotective> i was wondering if someone knew if to wrap a c library i should only include the header↵because there are more .h, .m .c files but idk↵cause in the example (`test_opendialog.c`) it just include `nfd.h` but if i run `gcc test_opendialog.c` i get `test_opendialog.c:(.text+0x3a): undefined reference 'to NFD_OpenDialog'`↵https://github.com/mlabbe/nativefiledialog 😕
01:37:21FromDiscord<Elegantbeef> You arent linking the library afaik

01:41:05FromDiscord<!Patitotective> but how do i get that `nfd.lib`? i have done `make` but it ouputs binarys not libs
01:42:05FromDiscord<Elegantbeef> > nfd.a will be built for release builds, and nfd\_d.a will be built for debug builds.\`
01:43:30FromDiscord<Elegantbeef> There should be a `build/lib`
01:44:11FromDiscord<!Patitotective> oh there is `libnfd.a` :D↵now i put that library next to my script?
01:44:23FromDiscord<Elegantbeef> No it's a static library
01:44:25FromDiscord<Elegantbeef> You link it
01:44:56FromDiscord<!Patitotective> what does _link_ means?
01:45:10FromDiscord<!Patitotective> like linux symlinks or?

01:52:53FromDiscord<demotomohiro> I think you need to link gtk related libraries.
01:53:04FromDiscord<loaf> do any of you have experience using emscripten
01:53:42FromDiscord<demotomohiro> Probably libnfd.a depends other libraries and you need to link them.
01:55:13FromDiscord<demotomohiro> I used emscripten long time ago.
01:56:00FromDiscord<loaf> isnt there a way to automatically generate the structural html/js?
01:59:25FromDiscord<demotomohiro> If I remember collectly, I just used html file copied from somewhere when I used emscripten.
01:59:37FromDiscord<loaf> oh
01:59:50FromDiscord<loaf> because im just going by this

02:06:39FromDiscord<demotomohiro> If you want to know what `-o` or `--shell-file` option do, you need to read emscripten manual.

03:25:32FromDiscord<morgan> https://nim-lang.org/docs/macros.html#bindSym%2C%2CBindSymRule

05:10:08FromDiscord<creikey> In reply to @Elegantbeef "thread local storage emulation": just read the wiki for thread local storage
05:10:19FromDiscord<creikey> why would it need to be "emulated"? You get thread local storage through winapi on windows right
05:12:12FromDiscord<Elegantbeef> I do not know
05:12:25FromDiscord<Elegantbeef> Think it's mainly for Mingw/pthread
05:37:41FromDiscord<Rika> TFW I always thought how “TLS” as in the protocol was emulated lol

05:46:03FromDiscord<leorize> that's emulation↵(@creikey)
05:50:51FromDiscord<leorize> "native" TLS is where the OS supports the allocation and declaration of these objects statically, so to speak
05:51:20FromDiscord<leorize> in Nim however it's just whether the C compiler supports `_Thread` or `thread_local`
05:54:19FromDiscord<Sabena Sema> its easy to add static constructors and destructors of your own
05:54:49FromDiscord<Sabena Sema> you can use flsalloc, but also one of the .crt$ sections is constructors and one destructors
06:05:45FromDiscord<OceanMongrel> can i just say not having to use brackets for function calls is making me quite happy
06:06:26FromDiscord<Elegantbeef> I think you can say that

06:12:52FromDiscord<huantian> weird that the bridge capitalizes usernames
06:13:54FromDiscord<Elegantbeef> Does `downloadFile` not work for you?
06:14:33FromDiscord<huantian> the question is less about how to download a file and more on how to do it concurrently with max concurrent downloads
06:15:53FromDiscord<Elegantbeef> Think a seq + callbacks is the way
06:17:48FromDiscord<huantian> yeah I might just do that tbh
06:18:21FromDiscord<morgan> great so i was making progress and now something is causing a segfault in the compiler and i am really confused what would be doing that

06:19:48FromDiscord<xflywind> Is someone familiar with pegs? Is grammar like https://github.com/nim-lang/Nim/blob/dc4cc2dca53e3772efb3654a4ddbbe8350d1db43/tests/stdlib/tpegs.nim#L306 correct?

06:24:47FromDiscord<Elegantbeef> Might need a full collection instead
06:24:53FromDiscord<huantian> hm I think I'll have to make multiple async http clients as well
06:25:44FromDiscord<Elegantbeef> Perhaps, also think this wont work due to the blocking `waitfor`

06:31:13FromDiscord<Elegantbeef> Ways to ruin jokes for $400 please alex
06:50:50FromDiscord<Rika> Put all futures into a sequence and await that?
06:51:19FromDiscord<Rika> I just skimmed through the question
06:51:21FromDiscord<Rika> BRB
06:51:23FromDiscord<Elegantbeef> Yea batches are easy
06:52:21FromDiscord<Elegantbeef> The ideal thing is something like my suggestion but without the waitfor but a sleeping while loop
06:52:43FromDiscord<Elegantbeef> Atleast i think
06:53:18FromDiscord<leorize> there's `asyncfutures.all()` if that's what you need
06:53:57FromDiscord<Elegantbeef> Yea that'd work for the batch method
06:55:08FromDiscord<Elegantbeef> The downside of batching is it waits until the longest async is done, so if you have like 7 10kb files and 1 1gb file you have to wait until the 1gb is done
06:57:15FromDiscord<Rika> There’s no fix to that, if you need all then you need all?
06:57:22FromDiscord<Rika> If you don’t need all then ???
06:57:36FromDiscord<Rika> You’ll have to know beforehand what you need for what part
06:57:39FromDiscord<Rika> That gets messy
06:57:58FromDiscord<Rika> There’s no reason to batch if you need all, and you’re gonna have to manually determine batches if you need some
06:57:59FromDiscord<Elegantbeef> eh you just make a buffer of them and iterate over it every so often in a sleeping loop

06:58:13FromDiscord<Elegantbeef> batches are the `all` method
06:58:16FromDiscord<Elegantbeef> you do 8 at a time
06:58:26FromDiscord<Elegantbeef> when those 8 are done you move to the next 8

06:58:41FromDiscord<Elegantbeef> Say you have 10 files
06:58:48FromDiscord<Rika> Yes so what’s the difference between doing eight at a time and doing all at the same time
06:59:01FromDiscord<Elegantbeef> you download 8 and before you can download the remaining 2 files you have to wait for the 1gb file to finish
06:59:03FromDiscord<Rika> You do all ten files one is massive, your bottleneck is only the massive file
06:59:24FromDiscord<Elegantbeef> Oh you're saying batch them all together
06:59:26FromDiscord<Rika> You do 8 at a time and the massive one is last, your bottleneck is the longest small file AND the massive file

07:01:06FromDiscord<morgan> ok yea that works
07:01:10FromDiscord<Elegantbeef> with a batch of like 8 you're atleast only dividing you max throughput by like 8
07:04:08FromDiscord<huantian> I mean an 8x improvement in download speed is non negligible
07:04:19FromDiscord<Rika> If it’s a thousand then yes batching is better

07:27:00FromDiscord<hmmm> broskis! gud firday to u all! Stupid question, if I have a recursive function, hmmm how many times can it calls itself before running out of stacks?
07:27:28FromDiscord<Elegantbeef> There is no set size depends on the function and your stack size
07:27:36FromDiscord<hmmm> hmmm
07:27:40FromDiscord<hmmm> how can I check?
07:28:00FromDiscord<Elegantbeef> If that's an actual issue perhaps dont do it recursively but instead do it iteratively
07:29:33FromDiscord<hmmm> yea I must try to turn it into a while proc but my cute function of 5 lines turns into a 30 lines monster lol so I wanted to know if it's really necessary
07:29:56FromDiscord<Elegantbeef> Your program is also probably faster due to lacking TCO
07:30:04FromDiscord<hmmm> wot is TCO
07:30:18FromDiscord<Elegantbeef> tail call optimization
07:30:52FromDiscord<Elegantbeef> It's an optimization for recursive calls
07:30:54FromDiscord<Elegantbeef> What's the code you have
07:32:39FromDiscord<hmmm> its something that traverses my weird tree. The recursive function checks if a node has children and if it has call itself again on the children. To make it work on a while I was trying to simulate a stack that tracks nodes with children but hmmm it's been messy so far
07:33:44FromDiscord<Elegantbeef> Ah tree traversal is one of the few things that's easier to reason recursively
07:33:49FromDiscord<hmmm> yea!
07:34:10FromDiscord<hmmm> all the recursive functions were very easy and natural to write and now I'm struggling lol
07:35:10FromDiscord<Elegantbeef> So what's the function do
07:36:21FromDiscord<hmmm> oh I started with the easiest one, headCount, it will simply count the number of nodes and children and output to total number
07:44:23FromDiscord<hmmm> the tree is made that every node can have from 0 to infinite children and so on, hmmm like a filesystem
07:49:04FromDiscord<Rika> How deep does it go
07:49:21FromDiscord<Rika> You can rest assured a few hundred in depth is fine, start worrying when you hit a thousand
07:51:21FromDiscord<hmmm> hmm for all purposes it should be fine, but I wanted to see if it was easy to turn the procs into iterative. So far it has been messy lol but it should be doable. They should also run faster I think

21:30:37FromDiscord<ratapenado> Hi, I have a stupid question: why is there a countup and countdown and not a simple count that works both way ? It would make things slower ?
21:30:58FromDiscord<Elegantbeef> Yes
21:31:04FromDiscord<Elegantbeef> Also `for x in 0..10` exists for count up
21:31:34FromDiscord<Elegantbeef> you can also make your own count iterator
21:34:07FromDiscord<demotomohiro> I think most of people dont use count that can go both way.
21:35:37FromDiscord<ratapenado> In reply to @Elegantbeef "Yes": Thanks
21:36:03FromDiscord<ElegantBeef> Damn bridge dieded
21:36:06FromDiscord<Elegantbeef> whoops
21:36:06FromDiscord<Elegantbeef> that should be `iterator` not `iterate`
21:36:06FromDiscord<Elegantbeef> Think the argument is "Count up is vastly more common and it's not worth slowing down the iterator for the odd cases it's not"
21:36:07FromDiscord<Elegantbeef> depending on what you're doing you also can just do `for x in min(a, b)..max(a, b)`

21:36:10FromDiscord<ElegantBeef> There we go
21:36:15FromDiscord<ElegantBeef> Dumb bridge is dumb
21:36:33FromDiscord<huantian> you could also have something like python's range, where you have to specify the step to be negative to count down

22:38:24FromDiscord<morgan> oh use a converter to create the full variant type?
22:38:41FromDiscord<Elegantbeef> Look at my code
22:38:50FromDiscord<Elegantbeef> I take in tuples and emit the flags
22:39:05FromDiscord<Elegantbeef> I of course dont use a complex variant cause there isnt any reason to imo

23:21:29FromDiscord<Ayy Lmao> In reply to @Elegantbeef "There are desructors/finalizers but": From the small amount of testing I did, I couldn't get destructors to be called with references. Maybe I did something wrong though.
23:21:52FromDiscord<Elegantbeef> You need to make a normal object with a destructor and do `MyRefType = ref Base`
23:22:13FromDiscord<Elegantbeef> Finalizers also can be used `new(MyRefType, myFinalizer)`

23:26:09FromDiscord<Elegantbeef> `--mm:orc`?
23:26:22FromDiscord<Elegantbeef> Destructors only work predicitibly with `orc`/`arc`
23:26:48FromDiscord<Elegantbeef> Works fine

23:27:01FromDiscord<Elegantbeef> works fine with refc\
23:27:44FromDiscord<Ayy Lmao> So you can't count on a destructor being called with a ref unless you are using orc or arc?
23:27:53FromDiscord<Elegantbeef> No you can
23:28:12FromDiscord<Elegantbeef> It's just that Nim's GC doesnt collect before the program exits so it doesnt seem to work
23:28:25FromDiscord<Ayy Lmao> Ah, I figured that might be the problem.
23:29:32FromDiscord<Elegantbeef> In a proper program it'll be proper, the only thing is they're not deterministic
23:29:43FromDiscord<Ayy Lmao> I guess I'm kind of confused if it is idiomatic in Nim to wrap cleanup code for a c lib in a destructor, or to expect the user to call the code manually.
