00:01:54FromDiscord<garett> hello all. I just finished a first draft of a Nim macro that converts Nim source code into GLSL. So far it just generates vertex and fragment shader code as strings, still working on making it generate an object initializer with the shader code strings and the necessary reflection info for uniforms and attributes
00:03:53FromDiscord<garett> Also made PRs to https://github.com/floooh/sokol-nim to update it to latest changes to sokol, making it possible to write simple graphical apps using OpenGL, D3D11, or Metal on Linux, Windows, and macOS
00:06:19FromDiscord<garett> I have a question. When I'm compiling the `sokol-nim` examples, I have to specify `--noMain`, because `sokol/app` implements the platform-specific entry point, then calls `NimMain`. I want to know whether it is possible to put the `--noMain` compiler switch in a `.nims` file so that when the main module depends on the module that implements the entry point, it will also automatically get the `--noMain` compiler switch
00:07:05FromDiscord<garett> It is not clear to me whether the `.nims` file for an imported module can add a compiler switch.
00:09:09FromDiscord<garett> In this case, let's say I'm compiling `nim c -r cube.nim`, where `cube.nim` is one of the examples that imports `main.nim`, which is another example module that implements the entry point required by the `sokol/app` module. Can `main.nims` introduce `--noMain` so that when I compile `cube.nim`, I don't have to type `nim c -r --noMain cube.nim`?
00:15:11PMunchYes
00:15:37PMunchDon't remember how, I think it's something like `switch(noMain)`
00:15:42PMunchAnayways, I'm off to bed

00:31:11FromDiscord<garett> either `switch("noMain")` or `--noMain` works if I put it in `cube.nims`, but has no effect if I put it in `main.nims`

00:43:10FromDiscord<ITS_N1GH7OWL> Hey there! So general question
00:43:29FromDiscord<ITS_N1GH7OWL> Am going into him, and I saw that it has the no gc option
00:43:39FromDiscord<ITS_N1GH7OWL> But I can’t find anything on freeing that memory..?
00:43:44FromDiscord<ITS_N1GH7OWL> Am I missing something orrrr
00:44:54*Fish-Face joined #nim
00:45:35Fish-FaceHello, I seem to have run into this bug https://github.com/nim-lang/Nim/issues/14873 but the "workaround" does not make sense and as far as I can tell in my case, does not work. Is any more known about this?
00:47:51FromDiscord<ITS_N1GH7OWL> --gc:none or does it just- never free anything literally
00:48:01FromDiscord<ITS_N1GH7OWL> There has to be some sort of manual control I’m missing 😅
01:06:21FromDiscord<ElegantBeef> you have to manuall dealloc with `none`
01:06:31FromDiscord<ElegantBeef> the is `alloc` `realloc` and `dealloc`
01:06:35FromDiscord<ElegantBeef> (edit) "the" => "there"
01:06:39FromDiscord<ElegantBeef> @ITS_N1GH7OWL ^
01:07:11FromDiscord<ITS_N1GH7OWL> Ohhhh thank you 😃
01:09:14FromDiscord<ITS_N1GH7OWL> @ElegantBeef just another question since I really don’t understand the underworkings of nim
01:09:34FromDiscord<ITS_N1GH7OWL> But a package built to use a gc would not work with no gc mode, correct?
01:10:57FromDiscord<ElegantBeef> Well it work but not free anything
01:11:51FromDiscord<ITS_N1GH7OWL> So for cases like that, it would be recommended to use arc mode for full performance?
01:11:54FromDiscord<ElegantBeef> With ARC/ORC there is very little reason to use gc:none
01:12:39FromDiscord<ITS_N1GH7OWL> Ohhh okay
01:13:03FromDiscord<ITS_N1GH7OWL> I’ll definitely do some benchmarking tonight, as I’m trying to build a heavily optimized minecraft Java based server and come from a C background
01:13:16FromDiscord<ElegantBeef> Arc is perfectly capable for running on embedded
01:13:17FromDiscord<ITS_N1GH7OWL> And well obviously building it in C would be idiotic syntax wise
01:13:33FromDiscord<ElegantBeef> So the overhead is clearly not a large amount 😄
01:13:48FromDiscord<ElegantBeef> If you want low latency you use arc, if you want high through put you checkout the GCs
01:14:14FromDiscord<ITS_N1GH7OWL> Okay I’ll definitely give arc a go! Thanks you!
01:14:36FromDiscord<ElegantBeef> Explains arc if you want to read about it/dont know what scope based memory management means https://nim-lang.org/blog/2020/10/15/introduction-to-arc-orc-in-nim.html

08:46:26FromDiscord<sealmove> but I want spaced and other stuff too
08:46:59FromDiscord<sealmove> (edit) "spaced" => "spaces"
08:48:32FromDiscord<ElegantBeef> `str.contains(yourSet)`
08:48:40FromDiscord<ElegantBeef> Ah sorry `only`
08:49:01*sz0 quit (Quit: Connection closed for inactivity)
08:49:48FromDiscord<ElegantBeef> Guess you'd need your own impl then
08:50:01FromDiscord<ElegantBeef> Good reference https://github.com/nim-lang/Nim/blob/version-1-4/lib/pure/strutils.nim#L2389
08:51:03FromDiscord<Unaimend> Not sure if which data types the stuff it string utils are but if they are sets just unite them
08:51:08FromDiscord<sealmove> thx ElegantBeef
08:51:16FromDiscord<ElegantBeef> They's sets so you can just `a + b`
08:51:26FromDiscord<ElegantBeef> Or `{a, b}` iirc
08:51:42FromDiscord<Unaimend> so it just be easy to just compose the base sets
08:51:58FromDiscord<ElegantBeef> Wonder if we need a `matches(a: string, c: set[char])`
08:52:28FromDiscord<Unaimend> In reply to @รєคɭ๓๏שє "thx ElegantBeef": i.e. str.contains(whitespace + letters)
08:52:41FromDiscord<ElegantBeef> they said "only"
08:52:48FromDiscord<Unaimend> In reply to @ElegantBeef "Wonder if we need": but we have `contains(s: string; chars: set[char]):`
08:53:07FromDiscord<ElegantBeef> matches would return true if all chars in the string are in the set
08:53:10FromDiscord<sealmove> In reply to @Unaimend "but we have `contains(s:": we do?.
08:53:19FromDiscord<ElegantBeef> yes it's in strutils
08:53:27FromDiscord<sealmove> ah ok but yes, it means different thing
08:53:49FromDiscord<Unaimend> yeah, did not get what you mean by only, sry
08:54:07FromDiscord<Unaimend> yeah
08:54:21FromDiscord<ElegantBeef> But yea might need a matches in the stdlib for set of chars since it's fairly common
08:54:21FromDiscord<Unaimend> should have read your requirement more carefully
08:54:52FromDiscord<Unaimend> that would be a good first issues for beginners
08:55:01FromDiscord<Unaimend> In reply to @ElegantBeef "But yea might need": that would be a good first issues for beginners
08:55:50FromDiscord<ElegantBeef> I suppose, but it takes me about 30 minutes so if a beginner wants to they best do it by tomorrow 😉
08:57:22FromDiscord<ElegantBeef> I tend to add things to the stdlib when they seem semi important so i'm a terrible person to suggest that it's a good first issue to 😛
08:57:59FromDiscord<Unaimend> 😂 picking all the low hanging fruits of the tree
08:58:33FromDiscord<ElegantBeef> Hey take that back scantuple is fantastic

09:01:31Oddmongeri'm reading Salewski's book, and at the end there are « strange questions » (without answer alas): http://ssalewski.de/nimprogramming.html#_strange_questions
09:01:50FromDiscord<Unaimend> Im wasting time by adding unnecessary plugins to my neovim 🙈 instead of working on bionin
09:01:55Oddmongeri wonder if it's possible to get a ref from a non-ref , without copy the ref with «new»
09:02:18FromDiscord<ElegantBeef> You cannot convert a non-ref to ref
09:02:18Oddmonger(which is not exactly getting a ref, as it's new variable referenced)
09:02:40FromDiscord<ElegantBeef> Remember non-ref's exist on the stack(typically) and refs do not
09:02:57Oddmongerrefs are on the stack ?
09:03:07FromDiscord<ElegantBeef> Plus refs are managed by the memory management
09:03:11FromDiscord<ElegantBeef> No non-ref's are
09:03:23FromDiscord<ElegantBeef> the refs exist on the stack as a ptr
09:03:30FromDiscord<ElegantBeef> the object lies somewhere on the heap afaik
09:03:37Oddmongerah ok
09:04:05FromDiscord<ElegantBeef> So you need to either use a ref object initially, question if `decls`'s `{.byaddr.}` will help you or use a `var T`
09:04:11*lritter joined #nim
09:04:43Oddmonger{.byaddr.} returns a ptr, doesn't it ?
09:05:13FromDiscord<ElegantBeef> well `var a {.byAddr.} = b` would propogate back to b
09:05:26FromDiscord<ElegantBeef> so `a = 100` changes b
09:05:28FromDiscord<ElegantBeef> So yes
09:06:11FromDiscord<ElegantBeef> Actually seems it's considered an int
09:06:57Oddmongercannort import decls with inim ?!
09:07:12Oddmonger(for {.byaddr.}
09:07:14FromDiscord<ElegantBeef> Cmon it's 2021 you use `std/inim`
09:07:21FromDiscord<ElegantBeef> (edit) "`std/inim`" => "`std/decls`"
09:07:26FromDiscord<ElegantBeef> I'm not tired you're tired!
09:07:35Oddmongerhéhé
09:07:48FromDiscord<ElegantBeef> But joke aside you should preface all stdlib modules with `std`
09:08:25FromDiscord<ElegantBeef> And if you're really anal retentive you can do `pkg/`
09:08:44Oddmongerpkg/ ?
09:09:24FromDiscord<ElegantBeef> for package manager packages
09:10:32Oddmongeri understand the need of «std/», because «nim-1.4.4/lib/std/decls.nim», but pkg/ ?
09:11:12FromDiscord<ElegantBeef> It's just to tell nim "I certainly want this from my packages not from this file"
09:11:32FromDiscord<ElegantBeef> say you have a `coolModule` and a package installed named `coolModule`
09:11:52FromDiscord<ElegantBeef> If you want to import the package you cannot, hence `pkg/coolmodule`
09:12:06FromDiscord<ElegantBeef> Yes i just camelcased a module, you're still more tired than me
09:13:08Oddmongercamel and snakes are strange animals
09:13:43Oddmongerthank you for the explain^w reminding
09:13:54FromDiscord<ElegantBeef> No problem
09:17:04FromDiscord<ElegantBeef> It's what i do take my pretend knowledge and disperse it to people who want to play pretend with me
09:18:47FromDiscord<Rika> How do I ensure I have no cycles so that arc works properly?
09:19:59FromDiscord<ElegantBeef> Arent cycles just recursively dependant types
09:20:42FromDiscord<ElegantBeef> So if you have an object that could potentially be a cyclical object you mark it with `{.acyclic.}`
09:20:52FromDiscord<ElegantBeef> Assuming of course you dont need it to be cyclical
09:21:45FromDiscord<ElegantBeef> Aside from that i figure you just run the code with `-d:useMalloc` and valgrind or whatever else
09:34:08FromDiscord<Rika> In reply to @ElegantBeef "So if you have": Not sure if this will prevent me from accidentally making a cycle
09:34:25FromDiscord<Rika> In reply to @ElegantBeef "Aside from that i": Valgrind can run on embedded?
09:36:54FromDiscord<clyybber> @Rika compiler will warn you if cycles can be created with arv

11:35:29threenpHi all! Been curious of nim for some time and finally have a good opportunity to try it out by patching a project. But I'm hitting a brick wall - I can't seem to read os env vars successfully
11:35:58*willyboar quit ()
11:36:58threenpSo this just produces an empty string:

11:40:22PrestigeWhat happens threenp ? just returns an empty string?
11:41:02threenpyes exactly
11:41:36PrestigeHow do you know that env var is set?
11:41:42threenpif i do getEnv("CONF_FILE", "blabla") it falls back to blabla
11:42:07threenpi run it like so:
11:42:07threenpCONF_FILE=test ./nitter
11:42:15threenpwhere nitter is the binary artefact
11:42:44Prestigetry putEnv("CONF_FILE", "foo") before getEnv and see if it returns anything? Also I don't think you need .string after getEnv
11:43:15threenpre string yeah, same without.. thanks, will see what putenv gives
11:45:26PrestigeIf that works, might want to try https://play.nim-lang.org/#ix=2V6U in a standalone file just to see if it's a Nim problem or something else.. idk what it would be otherwise
11:46:16threenpyeah it's really odd, came here as i'm new to nim and thought it might be some ecosystem particularity involved i may not be aware of

12:33:00Zoom[m]Nice seeing you here! How long you've been dabbling with Nim?
12:33:15ddevaultI don't exactly dabble with nim per-se, I just keep an eye on it
12:33:26ddevaultI poked at it several years ago
12:33:44ddevaultlanguages with C as an intermediate step are not generally my cup of tea
12:33:48FromDiscord<Recruit_main707> it probably wont work, but what happens if you wrap the dealloc function and then call that from within destroy?

12:37:17m33[m]Hi guys, I am giving nim a try... I would like to port my small python bots for mastodon (activitypub), I can't find mastodon/activitypub librairies, are you aware of such libs? (nim native)

12:37:29FromDiscord<Rika> no, not that i know of
12:37:38ddevaultit's difficult (and complicated) to generate idiomatic C from another target, and it adds a layer of indirection which complicates debugging
12:37:54FromDiscord<Rika> does mastodon have anything specific for bot creation?

12:44:41m33[m]<FromDiscord "<Rika> does mastodon have anythi"> not that I am aware off. In python mastodon.py let you create a client easily, at least for token based authentication and posting (tooting).
12:45:11FromDiscord<Rika> might not be hard to translate that then, maybe try it to improve in nim 😛
12:46:17Zoom[m]To stay on topic, with Leorize's help I've beaten Go in my countwords version (https://github.com/ZoomRmc/countwords_nim).
12:46:20Zoom[m]I've noticed we can calculate the hash for words as we go along, but there's no *public* way to pass the hash into a table. I've just included tables and modified a couple of procs (`inc` and `rawGet`) which gave a solid 7% boost in speed.
12:46:38Zoom[m]Is there any more civilized way to achieve the same?
12:47:14Zoom[m]And, is it reasonable idea for a std tables to have a backhatch for passing a hash in?

12:48:43m33[m]<FromDiscord "<Rika> might not be hard to tran"> I would prefer simply port the app logic at first, not mess with low level stuff (networking & all). It would be rewarding quicker... maybe it's not the right use case to begin with.
12:50:22FromDiscord<Rika> you dont have to mess at too low of a level if its not proprietary (REST, websockets), there are libraries to interface with those already
12:50:36FromDiscord<Rika> JWT? prolly one already as well
12:50:59m33[m]Guess I should play on code.golf before all this...
12:54:25m33[m]<FromDiscord "<Rika> you dont have to mess at "> unfortunately I already have investigated in this direction, it seems activitypub is rather complex to implement :/
12:54:50FromDiscord<Rika> oh i see

13:43:09FromDiscord<dain> do i need to know any C to use Nim
13:44:51FromDiscord<Clonkk> No you don't need to know C unless you're wrapping a C library in Nim
13:49:55Zoom[m]@dain it certainly wouldn't hurt, especially if you need to debug, but it's not strictly necessary.
13:54:40Fish-FaceHello, I seem to have run into this bug https://github.com/nim-lang/Nim/issues/14873 but the "workaround" does not make sense and as far as I can tell in my case, does not work. Is any more known about this?
14:16:17FromDiscord<dain> is there a way to get the implicit bool-casting that python does in if-statements
14:16:56FromDiscord<dain> sent a code paste, see https://play.nim-lang.org/#ix=2V7w
14:16:56FromDiscord<dom96> yes, you can create a converter
14:16:59Fish-Faceand on the topic of concurrency, it seems there is very little information about the actual semantics of the `parallel` block - I had assumed that it was only stuff that was `spawn`ed that happened in threads and that other stuff in the parallel block would be synchronous, but this appears not to be the case... is there actually documentation about this somewhere that I haven't found?

14:29:05FromDiscord<dain> if I remove the converter line it doesn't compile, so it is being used. but why is it echoing an integer rather than a boolean
14:30:28FromDiscord<Rika> not exists for integers
14:30:33FromDiscord<Rika> it is a bitwise not
14:30:40FromDiscord<Rika> so the converter does not run

15:26:55FromDiscord<rb3> Hey guys, is there a way to different assignment to a `var` and `let` variable? e.g. `var a = fn()` vs `let a = fn()`? I know there isn't return type overloading, so tried playing around with a proxy type that overloads `=copy`, but of course that didn't work. I just want to call a proc when a `var` instance of the proxy type goes out of scope.

16:01:51leorizewhat are you trying to achieve?
16:06:48FromDiscord<mlokis> is there some stdlib numeric concept?
16:07:02FromDiscord<mlokis> that defines all operators numbers have
16:07:21leorizeno, the stdlib use little to no concepts atm due to their buggyness
16:27:19FromDiscord<mlokis> how do i requier operator like `/=` in constraint? if i use `c /= c` it does not want to accept numerical types
16:27:47leorizecan you provide an example of what you want to do?

16:37:51leorizeYardanico: not sure if it's a bridge bug, but `*` are rendered as a weird circle thing.
16:40:07leorizemlokis: yea since it's ambigous, but you can define it yourself: https://play.nim-lang.org/#ix=2V8i
16:40:36leorizenote that self assignment of `a / b` can't work since `int / int = float`
16:41:07FromDiscord<mlokis> oh i see
16:41:13FromDiscord<mlokis> did not know that
16:41:26FromDiscord<mlokis> that makes sense
16:41:50FromDiscord<mlokis> so `//` like in python?
16:42:11leorizeour operator for integer division is `div`
16:46:25FromDiscord<mrotaru> how to get the folder from which a nim executable is running ?
16:47:11leorizeos.getAppDir()

17:19:26FromDiscord<Conifer> Nim is supported tho.
17:19:33FromDiscord<Conifer> but obviously its code runner thing
17:30:39FromDiscord<Goel> Probably if you open an issue on Code Runner they will fix it (if you are sure its not a bug with Better comments)
17:32:57FromDiscord<Conifer> Yeah it's not. Code.Runner works fine without it. Will have to open an issue later

20:38:17FromDiscord<mlokis> i hate how unions are called objects. it reminds me of java. and i dont like that

20:40:00FromDiscord<Yardanico> In reply to @mlokis "i hate how unions": huh?
20:43:19FromDiscord<Technisha> What are some things about Nim that may have changed from 1.2?
20:43:21FromDiscord<haxscramper> In reply to @Yardanico "huh?": `Type {.union.} = object`
20:43:30FromDiscord<Yardanico> In reply to @haxscramper "`Type {.union.} = object`": yes, I know, but that's only for C interop
20:43:40FromDiscord<Yardanico> we have object variants which are unions inside too, but that's hidden
20:43:47FromDiscord<haxscramper> No, isn't it just to declare union in nim?
20:44:29FromDiscord<haxscramper> And I thought C interop does not care about `struct/union/class` on C side
20:44:58FromDiscord<haxscramper> And it just copy-pastes types and field access.
20:45:36leorizeit's useful for ABI-based interop
20:46:52FromDiscord<haxscramper> Yes, but if I understand correctly ABI-based interop just means I have to declare new nim object that exactly matches layout of the C counterpart
20:46:55FromDiscord<haxscramper> Is that correct?
20:47:20FromDiscord<haxscramper> So `{.union.}` is still just a way to declare C-style unions in nim
20:47:56FromDiscord<haxscramper> And I'm not saying anything about their usefulness or not, just got confused with "but that's only for C interop" part
20:48:01leorizeyes, so how are you gonna declare a Nim object that matches a C union?
20:48:06FromDiscord<Technisha> Shit i forgot Nim doesn't have OOP, time to yeet the Java outta the window-
20:48:25*Mister_Magister quit (Quit: bye)
20:48:58FromDiscord<dom96> Nim does have OOP
20:49:23FromDiscord<Technisha> Wait what
20:49:27FromDiscord<dom96> but it leads to less ideal solutions in Nim so you shouldn't use it 🙂
20:49:43FromDiscord<dom96> unless you have a really good reason, there are use cases out there that demand it
20:49:48FromDiscord<Technisha> Does Nim have classes now? If so that's unholy...
20:50:18FromDiscord<Yardanico> @Technisha nim always had OOP
20:50:23FromDiscord<Yardanico> you can have OOP without classes
20:50:29FromDiscord<Technisha> Oh yeah i meant classes

22:22:57FromDiscord<ElegantBeef> Something isnt listing the default include paths?
22:24:37FromDiscord<nailuj29> i dont think you can use the include paths in an os
22:24:47FromDiscord<nailuj29> so it makes sense that it fails
22:25:07FromDiscord<ElegantBeef> No clue, you're compiling an OS so i dont see why you cannot
22:26:18FromDiscord<ElegantBeef> Like i know for the pico i had no issue with string.h

22:26:31FromDiscord<ElegantBeef> Though your build options might be different i guess
22:26:47FromDiscord<Yardanico> In reply to @ElegantBeef "Like i know for": when you're doing something fully standalone without libc - you don't have string.h
22:26:50FromDiscord<Yardanico> string.h is a part of libc
22:27:23FromDiscord<ElegantBeef> Shouldnt the string.h be included in the compilation, i dont C?
22:28:03FromDiscord<Yardanico> wdym?
22:28:12FromDiscord<Yardanico> string.h is a part of libc, it's not a part of C
22:30:23FromDiscord<ElegantBeef> Like i say, i know nothing
22:31:19FromDiscord<nailuj29> In reply to @Yardanico "string.h is a part": why would it be included then, or can you set nim to not use it
22:31:38FromDiscord<Yardanico> In reply to @nailuj29 "why would it be": because --os:any usually wants a libc, just a tiny one, but still
22:31:42FromDiscord<Yardanico> you can try -d:nimNoLibc also
22:32:01FromDiscord<Yardanico> ah yeah it should work in your case
