02:03:06FromDiscord<morgan> been working on a pixel art upscaler, it's now like 900 lines long. i think i need to break it up into a few files
02:03:26FromDiscord<morgan> 1.5x scaling that looks nice is hard
02:04:35FromDiscord<morgan> next im going to try using a DCT of the input 2x2 and some pixels around it (haven't decided on 4x4, 6x6, or 8x8) to sample the new 3x3 from
02:04:53FromDiscord<morgan> and then quantizing to the palette
02:05:24FromDiscord<morgan> eventually im gonna make a cli app from it using my cli input parser framework thing, tho i think i gotta do some more on that before it's done

02:54:42FromDiscord<morgan> ok so following on from #internals, does the compiler have any special treatment for range?
02:55:01FromDiscord<Elegantbeef> Yes it does
02:56:14FromDiscord<Elegantbeef> But i mean you can get compile time and runtime checks with distincts
02:56:23FromDiscord<Elegantbeef> sent a code paste, see https://paste.rs/NG3
02:56:59FromDiscord<Elegantbeef> Though they're not implicit conversions
02:57:06FromDiscord<Elegantbeef> But you can make a converter for your specific Factor
02:57:06*noeontheend quit (Ping timeout: 272 seconds)
02:57:14FromDiscord<morgan> right
02:59:17FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=3Yps
03:00:47FromDiscord<Elegantbeef> A reason that ranges are done in the compiler is the implicit conversion and also the nice type syntax
03:01:08FromDiscord<Elegantbeef> Like you can do `var a: 0..1` and there is no way to do that without the compiler support
03:02:12FromDiscord<morgan> yeah
03:03:08FromDiscord<morgan> `var b: 2x3` 👀
03:14:55FromDiscord<morgan> tempted to clone the compiler and poke around and see if i can get it working with `factor[2, 3]` instead of `Factor[[2, 3]]`, and add 2x3x5 etc for another way of encoding it
03:15:08FromDiscord<morgan> even if just for fun
03:15:28FromDiscord<Elegantbeef> It's not an easy task
03:15:34FromDiscord<morgan> i know
03:15:43FromDiscord<Elegantbeef> The compiler is not something very simple
03:15:54FromDiscord<Elegantbeef> Easier to use a macro to do it
03:15:59FromDiscord<morgan> yeah i was already poking around in the files
03:30:13FromDiscord<morgan> i think i’m gonna try and figure out all the syntax variations first

05:21:18FromDiscord<sushie> (edit) "https://play.nim-lang.org/#ix=3YpH" => "https://play.nim-lang.org/#ix=3YpI"
05:21:34FromDiscord<Yardanico> this is invalid code anyway, but yes, the compiler should show a proper error
05:21:36FromDiscord<sushie> (edit) "https://play.nim-lang.org/#ix=3YpI" => "https://paste.rs/7yo"
05:21:52FromDiscord<Yardanico> `const` is for compile-time constants
05:21:58FromDiscord<Yardanico> why do you want a `const` proc?
05:22:12FromDiscord<Yardanico> if you want to run it at compile-time, then you can just define a normal proc and call it in a `static` block
05:24:32FromDiscord<Yardanico> The difference between `var`/`let`/`const` in Nim is not the same as in some other languages. `var` means that the variable is created during runtime and is mutable, `let` - also created during runtime, and immutable (the variable itself, not its underlying data), `const` - a variable is created during compile time and is immutable
05:28:52FromDiscord<sushie> sent a code paste, see https://play.nim-lang.org/#ix=3YpJ

05:29:28FromDiscord<Yardanico> why won't it let you call it if you make it a normal proc and not a `const`?

05:42:32FromDiscord<Elegantbeef> It's a compiler bug that's quite odd
05:48:43FromDiscord<ripluke> can i use nim to get images in a terminal
05:49:04FromDiscord<Elegantbeef> Yes, now is there a wrapped API for it probably not
05:49:24FromDiscord<ripluke> how
05:49:30FromDiscord<Elegantbeef> https://sw.kovidgoyal.net/kitty/graphics-protocol/
05:50:00FromDiscord<Yardanico> https://github.com/jesvedberg/tpix for kitty graphics protocol, idk about other terminal emulators
05:50:09FromDiscord<ripluke> thats just for kitty, i was thinking something like w3m
05:50:25FromDiscord<Yardanico> so you mean pseudographics?
05:51:33FromDiscord<ripluke> nah like w3m can show images
05:51:54FromDiscord<Yardanico> just check how w3m does it, easy :P
05:52:10FromDiscord<Yardanico> "Best i understand you need to use a xterm derived terminal for this to work, because the sub-program used by w3m for this draws over the terminal window to make things happen."
05:52:16FromDiscord<Yardanico> also this sounds really hacky and not a good way to do things
05:52:17FromDiscord<Elegantbeef> > w3m and überzug both rely on x11 to draw an image in a subwindow. It is highly unlikely that either of the two can be made to work in Terminal without also modifying the tools themselves.
05:52:33FromDiscord<Elegantbeef> It doesnt render it in the window it renders a hidden window where the image should be
05:52:36FromDiscord<Yardanico> yep
05:57:17FromDiscord<ripluke> oh
05:57:19FromDiscord<ripluke> rip
05:57:45FromDiscord<Elegantbeef> Terminal emulators generally just emulate terminals and terminals of course couldnt display images

06:30:05om3gawhat I don't get. var declared in thread function's scope is thread local by default?
06:30:29FromDiscord<Elegantbeef> What?
06:31:07om3gaI'm asking the variable declared in thread procedure (in nim terms), will be accessible for that procedure only?
06:32:15FromDiscord<Elegantbeef> Safely yes
06:32:35om3gawhy I'm asking that, because something really strange happens, with the code that used to work without any problem before :)
06:32:57FromDiscord<Elegantbeef> I believe you should be able to pass the address to other threads and it can write, but i may be mistaken
06:33:08FromDiscord<Elegantbeef> It's all memory inside of a program so I imagine it's true
06:33:10om3ganow what I did, I used locks (posix mutex), and locked entire procedure
06:33:28om3gaso that helped
06:34:26om3gaI see concurency issues, which are issues more to application logic, not for the runtime
06:36:33om3gaeach thread here has a variable request, which initialized by library, and is a structure in C. By some reason it's content changes
06:36:52FromDiscord<Elegantbeef> Code?
06:37:08om3gaElegantbeef, just a second
06:37:12FromDiscord<Elegantbeef> Does the library you're using support threading?
06:37:23om3gaElegantbeef, sure
06:38:08om3gaI recently asked here couple of times about that, it is old fcgi lib (patched)
06:38:21om3gaI mapped it to nim (from C)
06:39:06om3gamy "mapping" had issues, but all of them are fixed, just a second, I will share the code
06:47:38om3gaElegantbeef: https://drive.google.com/file/d/1Zuh6ekg6-J-MSC_15sXIXOjdYuEkXNQW/view?usp=sharing
06:48:18om3gathis is the "compact" version of the server app
06:49:54*jjido joined #nim
06:51:11om3gawhat happens there, in proc worker, there is var request, which is C struct FCGX_Request. When http pipelined requests are sent to the fcgi app, then that var somehow being affected.
06:52:57FromDiscord<Elegantbeef> Google drive more like gitdrive amirite
06:54:27om3gasorry, I don't know where to upload files nowadays, without registration and sending sms
06:54:51om3gaI don't like Gdrive
06:54:57FromDiscord<Zectbumo> it bugs me when libs have "almost useful" functions. Take io.readLines() for example↵https://nim-lang.org/docs/io.html#readLines%2Cstring%2CNatural
06:55:09FromDiscord<Elegantbeef> Eh most people just host their code on a gitrepo
06:55:15FromDiscord<Elegantbeef> "almostUseful"?
06:55:44FromDiscord<Zectbumo> yeah, like who is going to want `n` lines. what generally we want is to iterate over all the lines
06:55:51FromDiscord<Yardanico> there's `lines` for that
06:55:56FromDiscord<Yardanico> https://nim-lang.org/docs/io.html#lines.i%2Cstring
06:56:09FromDiscord<Zectbumo> and if I don't get the number of lines I want then I can throw EOF if I wanted to
06:56:12FromDiscord<Yardanico> readLines is specifically if you only want to read `n` files from a file
06:56:15FromDiscord<Yardanico> and not all
06:56:25FromDiscord<Zectbumo> who does that?
06:56:34FromDiscord<Elegantbeef> Consider a file format with a header and you want to validate the file 😄
06:56:38FromDiscord<Yardanico> In reply to @Zectbumo "who does that?": if you want to read first 100 lines of 10 GB file
06:56:53FromDiscord<Yardanico> good like doing `"file.txt".readFile.splitLines[0..99]`
06:56:57FromDiscord<Yardanico> (edit) "like" => "luck"
06:57:08FromDiscord<Yardanico> why do you not like `lines` iterator? It's exactly what you're asking for
06:57:20FromDiscord<Zectbumo> I'll use `lines` yes
06:57:21FromDiscord<Yardanico> it's defined for both `File` and `string` (filename)
06:57:22FromDiscord<Elegantbeef> What's the behaviour om3ga?
06:57:38FromDiscord<Elegantbeef> I'm looking at the code now and it seems ok
06:58:09om3gaElegantbeef, in worker procedure, there is var request, with type FCGX_Request
06:58:23om3gait defined in fcgx_lib.nim
06:58:23FromDiscord<Elegantbeef> Also there is a `withLock(lock): echo "Hello"` 😛
06:58:25FromDiscord<Zectbumo> but I was just looking at the readLines (while I needed lines) and saw it pulls it all `n` lines into memory
06:58:55FromDiscord<Yardanico> so do you want the stdlib to be bigger or smaller? :P
06:59:13FromDiscord<Yardanico> In reply to @Zectbumo "but I was just": and of course it will put all lines into memory, since it's a `proc` and returns a seq
06:59:16FromDiscord<Yardanico> not an `iterator`
06:59:35FromDiscord<Elegantbeef> Just to be clear you did setup fastcgi to work with multithreading? Generally libraries need that explicitly
06:59:59om3gaElegantbeef, sure, I used that lib in C before
07:01:19FromDiscord<Zectbumo> In reply to @Elegantbeef ""almostUseful"?": yes almost, as in, just use `lines`. maybe `readLines` came out first and then someone came out and made `lines` because `readLines` was "almost useful, but didn't cut it". for example, PHP had a lot of "almost useful" functions and kept adding substr1() substr2() substr3(). it was just forehead slap after forehead slap
07:01:22om3gamaybe I forgot something, and don't remember (here is more than 10 tasks running with that lib which were written long ago in C). But how I see now, it's not ok
07:01:24FromDiscord<Elegantbeef> Oh om3ga you've got two procs that point to the same procedure
07:01:41om3gaElegantbeef: where?
07:01:45FromDiscord<Elegantbeef> `proc FCGX_InitRequest(): int {.header: "fcgiapp.h", varargs.}` and `proc FCGX_InitRequest(request: ptr FCGX_Request; sock: cint; flags: cint): cint {.header: "fcgiapp.h", varargs.}` go to the same proc, that doesnt seem right
07:02:18om3gaOMG
07:02:24om3gajust a second
07:03:03FromDiscord<Elegantbeef> Where's pmunch to scream "Should've used futhark" 😄
07:03:17FromDiscord<Yardanico> also, is `varargs` really needed here if all arguments are already in the proc definition?
07:03:27FromDiscord<Elegantbeef> It's not
07:03:38FromDiscord<Elegantbeef> They probably just seen it in some C code and thought it was
07:04:08om3gayes. this looks like the reason
07:04:16FromDiscord<Elegantbeef> also you can do `{.push header: "fcgiapp.h".}` `{.pop.}`
07:04:23FromDiscord<Elegantbeef> Dont need to annotate every single proc with the header
07:04:31PMunchOh yeah, Futhark wouldn't mess up like that :P
07:04:32om3gaI used c2nim
07:04:51FromDiscord<Elegantbeef> Fuck the demon is here
07:04:55PMunchMuhahah
07:04:55om3gaand strange thing, it work'd before
07:05:04FromDiscord<Elegantbeef> Anyway well i have the code want me to touch it up a bit? 😛
07:05:21om3gaElegantbeef sure
07:05:22PMunchYou're the one who called me by my true name and summoned me, don't act all surprised now
07:06:25om3gaI spent hours with debugger, with pipelined http requests, it just corrupts request var content
07:06:59FromDiscord<Elegantbeef> Is there any reason for `Shared2` isnt that just a `distinct cint`?
07:07:08om3gacausing segfaults (because Accept_r frees, and re-inits stuff in that struct)
07:07:55om3gaElegantbeef, yeah, fcgi procs need cint
07:08:11FromDiscord<Elegantbeef> So then it's just a distinct cint
07:08:22om3gayes
07:09:09FromDiscord<Elegantbeef> It's not much but https://play.nim-lang.org/#ix=3Yq4
07:09:54FromDiscord<Elegantbeef> Guess that should be `sys[] = Shared2(-1)`
07:10:25FromDiscord<Elegantbeef> Anyway glad to have helped did c2nim cause the issue or you?
07:10:58om3gainteresting, but withLock may not work with that lib
07:11:40FromDiscord<Elegantbeef> I mean it should, but meh
07:11:56om3gaELephantbeef, thank you very much, I will fix imports from C, and verify if everything is ok
07:11:58FromDiscord<Elegantbeef> I have to think about the nine slice i added to my gui system and how to best work with it

08:13:32FromDiscord<Elegantbeef> I've been shouting about flatpak for a few weeks now 😄
08:17:37PMunchUgh, flatpak is just bringing us down to Windows level..
08:17:48FromDiscord<Elegantbeef> How?
08:17:58FromDiscord<Elegantbeef> Are you mistaking it for appimage?
08:18:03PMunchAh, maybe
08:18:28FromDiscord<Elegantbeef> Flatpak is distributed the same as your other software in a nice manager, it's just distro agnostic
08:19:04FromDiscord<Elegantbeef> In other words if it works in one place with flatpak it works everywhere
08:19:06PMunchHmm, so it's just like another separate manager?
08:19:48FromDiscord<Elegantbeef> Yes, i'd much prefer it in the package manager, but i think flatpak solves the issue much more elegantly than relying on X maintainers for Y distros
08:20:33FromDiscord<Elegantbeef> In an ideal world you just setup flatpak on your distro(many do this automatically) and then just `flatpak install choosenim`
08:21:07FromDiscord<Elegantbeef> Or use your GUI if you're one of those and it'd appear in there
08:22:27FromDiscord<Elegantbeef> Appimage is the more windowsy binary image
08:22:53FromDiscord<Elegantbeef> Which i think is sensible for paid proprietary software and non steam games

08:40:23FromDiscord<Rika> I am pretty sure Flatpak is closer to windows than AppImage.
08:40:59FromDiscord<Rika> Someone has definitely sent this before
08:41:01FromDiscord<Rika> https://ludocode.com/blog/flatpak-is-not-the-future

08:42:36om3gaPMunch, maybe I'm tired or doing everything wrong but it says Fatal: 'stdarg.h' file not found
08:43:11FromDiscord<Rika> Even with these extra arguments I don’t think I will ever use either Flatpak or Snap
08:43:38FromDiscord<Rika> And if the binary is an AppImage I would extract it and delete the dependencies
08:43:44FromDiscord<Rika> If something doesn’t work I’ll deal with it
08:46:02FromDiscord<Elegantbeef> Yea I mostly try to avoid flatpak, but fragmentation is an issue that needs resolved somewhere for a reduction of work 😄

09:02:18FromDiscord<Rika> He does
09:02:26FromDiscord<Elegantbeef> Oh i'm blind
09:02:27FromDiscord<heinthanth> 0 leaks of 0 total leaked bytes

09:03:35FromDiscord<heinthanth> I looked for `free()` call in generated C code. But how nim free that allocated memory. Or `leaks` command on macOS did wrong ...
09:03:49FromDiscord<Rika> Try Valgrind
09:04:18FromDiscord<heinthanth> Ohh ... valgrind does not support later macOS.
09:04:25FromDiscord<Elegantbeef> This is a fools errand Nim doesnt track `ptr`
09:04:35FromDiscord<Rika> It really doesn’t
09:04:43FromDiscord<Elegantbeef> If it's a `ptr` there is no deallocation
09:04:44FromDiscord<Rika> So even if you didn’t disable anything it would have leaked
09:07:41FromDiscord<everyone> how do i split a string using a for loop?

09:09:37FromDiscord<heinthanth> I was like WTF, how nim deallocate that allocation without `free()`
09:09:42FromDiscord<Elegantbeef> I can say for certainty that memory is not freed, given that `ptr`s are raw C pointers 😄

09:19:30FromDiscord<heinthanth> valgrind always report "All heap blocks were freed -- no leaks are possible"

09:31:03FromDiscord<heinthanth> this case is super weird ...
09:31:09FromDiscord<golova> Maybe you should check via godbolt?
09:31:10FromDiscord<Elegantbeef> try `--cc:clang`
09:31:16FromDiscord<golova> Or disassembler idk
09:31:24FromDiscord<Elegantbeef> You will need to download clang of course
09:32:09FromDiscord<heinthanth> sent a code paste, see https://paste.rs/E1g
09:32:29FromDiscord<Elegantbeef> Well give it a whirl and see if you can find the leak

09:32:46FromDiscord<heinthanth> no no ... the same ... all free'd
09:33:06FromDiscord<Elegantbeef> I have to believe your GC is being set somewhere
09:33:33FromDiscord<Elegantbeef> When you compile does it have a unexpected `config` loaded?
09:33:47FromDiscord<Elegantbeef> The first messages it goes through are config files it's loading

09:33:59FromDiscord<heinthanth> just installation defaults
09:34:07FromDiscord<heinthanth> I just downloaded https://nim-lang.org/install_unix.html and extract

09:36:07FromDiscord<Elegantbeef> It'll print out during Nim compilation the GC it uses
09:36:15FromDiscord<Elegantbeef> So if all things are proper should say `"None"`

09:51:08FromDiscord<Rika> “Are you compiling the right file”
09:52:22FromDiscord<heinthanth> Of course.
09:52:26FromDiscord<heinthanth> There's is only one file
09:52:55FromDiscord<heinthanth> I'm just testing around if I can disable GC completely. Sometimes, I love do allocation manually.
09:54:05FromDiscord<Rika> This is very strange
09:54:21FromDiscord<Rika> Maybe it has to do with the other flags you added
09:55:21FromDiscord<heinthanth> Idk, if I can ping some nim member I know.
09:55:31FromDiscord<heinthanth> I feel super weird about this case.
09:56:19FromDiscord<heinthanth> @Araq ... sorry to bother you. What do you think about this case.
10:00:49FromDiscord<tandy> why am i getting `Error: undeclared identifier: 'isNil'` when using it on an object

10:39:45FromDiscord<Yardanico> the problem is related to `pkg/[listenbrainz, lastfm],`
10:39:56FromDiscord<Yardanico> @tandy do those also have some User type or not? or some client variable
10:40:32FromDiscord<Yardanico> listenbrainz exports client

10:40:37FromDiscord<tandy> fuck
10:40:50PMunchom3ga, sorry I was off for lunch. In general you don't want to put the /usr/include directory as a path argument as that would import all sorts of things

13:03:28FromDiscord<ambient> and its running only in Rosetta
13:04:23FromDiscord<Yardanico> why not build nim for arm64?

13:13:44FromDiscord<everyone> GUYS.....how do print statements work?
13:13:51*ltriant quit (Ping timeout: 276 seconds)
13:13:53FromDiscord<ynfle> Because compilation itself is fine
13:13:59FromDiscord<everyone> do they just spilt it?
13:14:08FromDiscord<ynfle> In reply to @uncle jim "GUYS.....how do print statements": `echo "Hello", ", world"`
13:14:16FromDiscord<everyone> In reply to @ynfle "`echo "Hello", ", world"`": ik that
13:14:25FromDiscord<everyone> but how do they work under the hood?
13:14:36FromDiscord<everyone> how do they print the stuff between ""
13:14:49FromDiscord<everyone> or a variable
13:14:49FromDiscord<Yardanico> In reply to @uncle jim "how do they print": just call the relevant system/standard C library routines
13:14:58FromDiscord<Yardanico> worst case you use linux system calls to write to the file descriptor
13:15:06FromDiscord<ynfle> In reply to @uncle jim "how do they print": They don't print stuff in between
13:15:19FromDiscord<ynfle> It call `$` on every parameter passed in

13:16:28FromDiscord<ynfle> What part don't you understand?
13:16:42FromDiscord<ynfle> `$` is nim's `toString` operator by convention
13:17:07FromDiscord<everyone> i am not asking it specifically for nim
13:17:17FromDiscord<everyone> all languages in general
13:17:22FromDiscord<Yardanico> it works differently in different languages
13:17:42FromDiscord<ynfle> What is you question then?
13:17:44FromDiscord<everyone> In reply to @Yardanico "it works differently in": python should be easy
13:17:52FromDiscord<ynfle> What do you mean?
13:18:02FromDiscord<ynfle> Like how does it interact with the operating system?
13:18:23FromDiscord<ynfle> Well Unix, it just write to the processes `/dev/stdout` file and the OS takes care of the rest
13:18:51FromDiscord<everyone> In reply to @ynfle "What is you question": for eg in python:
13:19:11FromDiscord<everyone> sent a code paste, see https://paste.rs/uuy
13:19:23FromDiscord<everyone> how does it only print the `ello`
13:19:41FromDiscord<Yardanico> we have #offtopic for that
13:19:54FromDiscord<Yardanico> please ask such questions that are about programming in general there :)
13:20:00FromDiscord<Yardanico> or maybe in #langdev , but in your case #offtopic would be a bit better
13:20:40FromDiscord<ambient> seems theres no way but manual git pull and copy files to right locations to get Nim for arm64
13:20:41FromDiscord<everyone> In reply to @Yardanico "please ask such questions": oke

19:54:37FromDiscord<Rika> In reply to @deech "How do I combine": you dont
19:54:44FromDiscord<Rika> you lose MCS with enforced qualification
19:54:48FromDiscord<Rika> no way around it afaik
19:55:10FromDiscord<Rika> i mean in terms of explicit "nice" syntax, of course theres probably some hacky way you could
19:58:18FromDiscord<deech> A different syntax for module qualification vs. mcs vs. field access would be nice, conflating all three into the dot looks nice but make code hard to understand.
19:58:45FromDiscord<huantian> I feel like module qualifcation isn't used enough to justify it tbh
20:05:35FromDiscord<Andreas> @planetis so may i ask you about how to use it in my case - cos' the runnable examples don't help me out. I read in some C++/Atomics blogs, that one can load a pointer, copy/clone the shared object, make changes on the local clone, then compareAndExchange. I'm working on a data-structure and like to try this approach with a graph of `ref object variant`. But the compiler wont let do this 🙂
20:07:08*xet7 quit (Remote host closed the connection)
20:07:47FromDiscord<planetis> you need a Atomic[ref T] but that's not allowed only type AtomType = SomeNumber | pointer | ptr | char | bool
20:08:42FromDiscord<planetis> there are threading/smartptrs SharedPtr for this job
20:08:58FromDiscord<Andreas> In reply to @planetis "you need a Atomic[ref": hmm, that is my impression. But a ref object can be 'downgraded' to a raw-pointer, can it ?
20:09:14FromDiscord<planetis> but most likely you should stay with a pointer
20:09:44FromDiscord<planetis> it can but incRef/decRef are not threadsafe
20:11:16FromDiscord<planetis> Now that I think about it, it might have been better if SharedPtr was a distinct ptr
20:11:47FromDiscord<Andreas> In reply to @planetis "but most likely you": ok, i'm confused 😉 do you mean a Smart/Unique/Shared-Ptr from the threading/atomics-lib or a dumb raw-pointer ?
20:12:24FromDiscord<planetis> yeah a dumb one
20:12:38FromDiscord<Andreas> In reply to @planetis "Now that I think": do these Smart/Shared=Ptr have some sort of aquire/release semantics ?
20:12:56FromDiscord<Andreas> (edit) "Smart/Shared=Ptr" => "Smart/Shared-Ptr"
20:12:57FromDiscord<planetis> but I should make Atomic[SharedPtr] work somehow
20:13:23FromDiscord<Andreas> (edit) "Smart/Shared-Ptr" => "Smart-/Shared-Ptr"
20:13:45FromDiscord<planetis> In reply to @Andreas "do these Smart-/Shared-Ptr have": no they just atomically increment / decrement a counter
20:14:44FromDiscord<Andreas> In reply to @planetis "yeah a dumb one": and a dump one i get by `my_thing.unsafeAddr` ?

20:30:11FromDiscord<planetis> but what kind of queue?
20:31:27FromDiscord<Andreas> In reply to @planetis "but what kind of": hmm, size limited, thread-safe, put stuff in on the left and pop it from the right, so LIFO it is..
20:32:07FromDiscord<planetis> single producer/ consumer?
20:34:53FromDiscord<Andreas> In reply to @planetis "single producer/ consumer?": good question, not sure yet. Its not critical. Could be any combination many producers : one consumer could be the scenario.. yes many-to-one, the one threads job is to fix orphaned-branches in the tree, that other thread have produced, as a result of a node removal..
20:34:59FromDiscord<planetis> if so sync/spsc, the rest either use std/channels? or port one yourself
20:35:20FromDiscord<planetis> where is std/channels I can't find it, wtf happened?

21:27:39FromDiscord<morgan> sent a code paste, see https://play.nim-lang.org/#ix=3Yt4
21:27:54FromDiscord<Elegantbeef> ok?
21:28:05FromDiscord<morgan> that's the open files and ports
21:28:34FromDiscord<morgan> i'll look into the project settings
21:28:55FromDiscord<Elegantbeef> https://github.com/saem/vscode-nim#options it's mentioned in here
21:31:59FromDiscord<morgan> ok maybe it's the nim.project, since i'm `include`ing a file atm
21:32:19FromDiscord<morgan> tho actually i probably don't need to
21:32:32FromDiscord<morgan> yeah i don't think i need to
21:32:39FromDiscord<Elegantbeef> include is literally satan
21:35:34FromDiscord<morgan> ok why does importing from another file not let me use stuff defined in it?????? it keeps displaying errors
21:36:00FromDiscord<morgan> oh
21:36:04FromDiscord<morgan> im dumb
21:36:15FromDiscord<morgan> before it was all in one so i wasn't exporting anything i declared
21:41:02FromDiscord<voidwalker> how do i debug a startprocess, to see its execution line ? executable starts but does not appear to be doing what I intended
21:42:03FromDiscord<Elegantbeef> you can pass the option `poEchoCmd` and it'll show what it's running
21:46:33*noeontheend joined #nim
21:52:54FromDiscord<voidwalker> hmm looks good, it might be that it needs its output read to progress ?

22:13:45FromDiscord<voidwalker> `while myproc.running: discard myproc.readLines` how else can i do this ? without blocking
22:14:51FromDiscord<Elegantbeef> async perhaps
22:18:52FromDiscord<voidwalker> would another kind of exec proc work, that I don't have to read its output ?
22:20:30FromDiscord<Elegantbeef> I mean you dont need to read the output
22:21:12*gsalazar quit (Ping timeout: 252 seconds)
22:21:34FromDiscord<Elegantbeef> you can just do `while myProc.running: discard`
22:22:02FromDiscord<Elegantbeef> Think there is also a `waitForExit`
22:22:39FromDiscord<voidwalker> yes but i want to let the program run in the background, and have some kind of watchdog process that checks if it's done (it produced a certain file)
22:23:15FromDiscord<Elegantbeef> So then just have the process run then check if it's finished when you need to
22:24:56*Guest21 joined #nim
22:25:05Guest21hi!
22:25:35FromDiscord<voidwalker> but it does not start working if I don't read its output. that's why I asked if there is an alternative (besides using async, which I don't know how to use yet, but I will read)
22:26:10FromDiscord<Elegantbeef> You shouldnt need to read the output for a process to wrok
22:32:55FromDiscord<dom96> @voidwalker you should be able to also have the process output its stdout to your process' stdout
22:33:17FromDiscord<dom96> if you're just debugging that should work quite well
22:34:54*noeontheend quit (Ping timeout: 244 seconds)
22:37:29FromDiscord<voidwalker> How would I do that ?
22:41:28FromDiscord<j-james> In reply to @MorganAlyssa "is there any way": this is a known bug: https://github.com/nim-lang/Nim/issues/11679
22:44:14FromDiscord<morgan> good to know
22:45:16*ltriant joined #nim
22:55:46FromDiscord<dom96> Hopefully the likes of https://github.com/nim-lang/langserver/ can manage the nimsuggest process to prevent it running wild
22:57:44FromDiscord<dom96> In reply to @voidwalker "How would I do": use the `poParentStreams` ProcessOption
22:58:11FromDiscord<dom96> or just use `execCmd` which does it implicitly https://nim-lang.org/docs/osproc.html#execCmd%2Cstring
22:59:28FromDiscord<voidwalker> I just tried the poParentStreams. I get the first line, and then the process turns into a zombie instead of continuing
22:59:59FromDiscord<voidwalker> It should output a text progress bar.. maybe that's too complex
