05:57:52FromDiscord<pmunch> Yeah I've been saying for ages that we should have a simple proc or template for doing this in the stdlib. At least that way if it ever changes stuff will still work↵(@Yepoleb)
05:59:37FromDiscord<Yepoleb> It seems like almost everyone eventually needs it
05:59:41FromDiscord<pmunch> @newlibarian\: embedding into your game can simply be done through staticRead. You might want to bundle them up and compress them though if you're doing this for all your assets.
06:04:10FromDiscord<ringabout> In reply to @Yepoleb "It seems like almost": Perhaps https://github.com/nim-lang/Nim/issues/14810
06:04:10FromDiscord<Rika> Isn’t there a third party library for that
06:15:42FromDiscord<Yepoleb> In reply to @ringabout "Perhaps https://github.com/nim-lang/Nim/issues/1481": That describes the problem but never went anywhere

07:02:20FromDiscord<Phil> In reply to @Hourglass, When the Hour Strikes "Does Nim have a": Yes, nim has a webdriver package that e.g. the forum uses for integration testing
07:02:31FromDiscord<Phil> Which uses firefox I think

07:13:31FromDiscord<newlibarian> yes, how do i compile a game to web?
07:14:55FromDiscord<Rika> Not all libraries in Nim are able to be compiled into JavaScript

07:42:53Amun-Ranewlibarian: it's almost as simple as running four commands. https://nim-lang.org/install_unix.html

08:16:44FromDiscord<newlibarian> nimble install sdl2_nim@#legacy
08:16:49FromDiscord<newlibarian> where does it install to?
08:16:57FromDiscord<Elegantbeef> `.nimble/pkgs`
08:20:38PMunch@Elegantbeef, oh creating pretty header files for Nim libraries? That's pretty cool actually, would certainly help if you wanted to develop a dynamic library in Nim
08:21:13PMunchBy the way is `intptr_t` the correct in `doThing`? Wouldn't that just be passed by value?
08:21:34FromDiscord<Elegantbeef> `intptr_t` is an integer the size of a pointer
08:24:21FromDiscord<Elegantbeef> I suppose one could use the target arch to emit specific integer sizes
08:25:47FromDiscord<Phil> I continue to be reaffirmed that java as a language with its constructs is not as much of an atrocity as its community with 5 billion abstraction layers
08:26:07FromDiscord<Phil> Ah, that's wrong channel, thought this was offtopic, one sec
08:26:17FromDiscord<Elegantbeef> lol
08:26:38FromDiscord<Elegantbeef> Irc and matrix will always see that you goofed!
08:26:55FromDiscord<Phil> Oh no, my life is over
08:27:15PMunchAnd since it's in the main channel it's also backed up on irclogs.nim-lang.org
08:28:13FromDiscord<Elegantbeef> I think at one point my password manager accidentally clicked element and i pasted a random generated password for something into the irclogs 😄
08:31:28FromDiscord<newlibarian> is nim a transcompiler or both compiler and transcompiler? in haxe it's a transcompiler.
08:32:08FromDiscord<Elegantbeef> Depends on your definition of what transpilation is
08:32:09PMunch@newlibarian, https://peterme.net/is-nim-a-transpiler.html
08:32:27PMunch@Elegantbeef, ooh, that's no fun
08:32:41*onetwo quit (Quit: The Lounge - https://thelounge.chat)
08:32:54FromDiscord<Elegantbeef> I mean it's completely fine cause i use randomly generated passwords 😄
08:37:57*onetwo joined #nim
08:39:40PMunchSure, as long as you remembered to change it afterwards :P
08:45:54FromDiscord<Phil> Actually, do C-compilers go C --> Assembly --> Binary or do they go C --> Binary?
08:46:30FromDiscord<Elegantbeef> They go through assembly
08:46:35FromDiscord<Elegantbeef> I mean that's even a short path
08:46:46FromDiscord<Elegantbeef> They are multiple stages and it's all lowerings
08:46:52FromDiscord<Phil> Because IIRC the "transpile" chain would be:↵Nim --> NimAST --> C --> C-AST (I assume (?)) --> Assembly --> ??? --> Binary
08:47:04FromDiscord<Elegantbeef> Lol
08:47:12FromDiscord<Elegantbeef> What a simplification
08:47:42FromDiscord<Phil> I mean, I'm pretty much ignoring all of Nim's pre-processor stuff, so yeah
08:47:48FromDiscord<Elegantbeef> For clang it's more like C -\> SomeAst -\> LLVM IR -\> LLVM -\> Assembly -\> Binary
08:47:50FromDiscord<Phil> And likely other low-level details
08:48:09FromDiscord<ringabout> Transpiler might use AST to AST transformation directly, which is more easier to generate code.
08:48:18FromDiscord<ringabout> (edit) "transformation" => "transformations"
08:48:23FromDiscord<ringabout> (edit) removed "more"
08:48:27FromDiscord<Elegantbeef> Many compilers have their own intermediate representation that people often remove from the step
08:48:39FromDiscord<Phil> So basically after Nim-AST all bets are off on how that chain looks like because it depends on the used toolchain after?
08:48:45FromDiscord<Elegantbeef> The definition of transpilation is always so hand wavy
08:49:02FromDiscord<Elegantbeef> Of course all the C compilers are different
08:49:18FromDiscord<Elegantbeef> There's a reason they all offer different levels of optimisation and compilation speed
08:50:03FromDiscord<Phil> Was more that the idea was floated that Nim-AST e.g. might be turned directly into a C-AST and then handed to a compiler, rather than creating C-code in between
08:50:36FromDiscord<Elegantbeef> Yea that doesnt make any sense
08:50:37FromDiscord<Elegantbeef> Each compiler has it's own AST
08:50:45FromDiscord<Elegantbeef> There is no "C AST standard that everyone must follow"
08:50:47FromDiscord<ringabout> There is an RFC for AST to AST transformations.
08:51:16FromDiscord<Elegantbeef> There is?

14:09:46FromDiscord<Nerve> I'm trying to translate some PHP code that slices an associative array. In PHP, associative arrays preserve order and `array_slice` returns the slices with the key-value pairs in the order they were entered. Can I replicate this with ordered tables? Or do I just use a sequence of 2-tuples?
14:12:40FromDiscord<ringabout> Ordered tables seem to be a simple option.
14:14:25FromDiscord<Nerve> How do you slice them?
14:15:41FromDiscord<ringabout> Do you also need to index them using `key`?
14:16:03FromDiscord<Nerve> Presumably yes, though that seems to be out of the scope of the file I'm looking at
14:16:30FromDiscord<ringabout> You might use table indexed seqs.
14:16:36FromDiscord<4zv4l> can I put the documentation for a `proc` up from its body or I have to write it under it's declaration ?

14:17:51FromDiscord<ringabout> In reply to @Nerve "Presumably yes, though that": You store `(key, value)` pairs to seqs, get the index of the current element and store (key, index) to tables.
14:17:57FromDiscord<ringabout> (edit) "In reply to @Nerve "Presumably yes, though that": You ... store" added "might"

17:31:58FromDiscord<Hourglass [She/Her]> That's because of how Nim does casing iirc
17:39:50FromDiscord<Phil> In reply to @Gabben "Is this case related": It is not.↵Nim is type insensitive and ignores underscores, so the following are all the same symbol:↵`is_modal, isModal, IS_MODAL, is_mo_dal, ismodal, ISMODAL`
17:41:21FromDiscord<Phil> The benefit of this is that we can have both pythonistas and folks from camel-case'd languages write code that does not interfere with each other's style.↵Just because my library uses `addCrudRoutes` doesn't mean you're forced to use it that way, you can use it as the more readable `add_crud_routes` to you
17:41:54FromDiscord<Phil> (edit) "you" => "you.↵That means all your code can be in the style that you want while all my code can be in the style that I want."
17:42:29FromDiscord<Phil> That is at the expense that in fairly rare cases you will run into this kind of symbol ambiguity issue like you did, where you have an enum value "HelloReply" and a const "HELLO_REPLY".
17:43:00FromDiscord<rakgew> wait, I thought it actually looks at the case of the first char no?
17:43:02FromDiscord<Phil> As long as you're on nim 1.6. the best practice is to prefix enums, so `kHelloReply` in your case
17:43:04FromDiscord<Rika> it does
17:43:11FromDiscord<Phil> In reply to @rakgew "wait, I thought it": That it does, my description was incomplete
17:43:28FromDiscord<Rika> more incorrect
17:43:28FromDiscord<Phil> I was too focused on trying to present Pros and Cons of this feature
17:43:29FromDiscord<rakgew> is\_modal is not the same as IS\_MODAL
17:43:35FromDiscord<Rika> yes
17:44:01FromDiscord<rakgew> but anyway - I am a big fan of that feature.
17:44:52FromDiscord<rakgew> for my old eyes I like to be able to put the underscores as spacing.. \:-D
17:44:54FromDiscord<Phil> 🤷 , the more key point to me was to elaborate on why it matters as folks tend to generally be very surprised by it
17:45:23FromDiscord<Phil> I dunno why I just got hung up on camelcase
17:47:23FromDiscord<Gabben> In reply to @Isofruit "As long as you're": Does this mean that on Nim 2.0 this code will work?
17:51:54FromDiscord<Phil> In reply to @Gabben "Does this mean that": No, because that is about 2 enum values of different enums having the same name. In your case you have a const an an enum share the same name.
17:52:14FromDiscord<Phil> (edit) "name." => "name and allowing that to happen because nim can infer which enum is meant a lot of the time."
17:52:21FromDiscord<Phil> (edit) "an" => "and"
17:53:12FromDiscord<Phil> your options are either going `helloReply` (or anything else with lower-case h), renaming the variable completely, prefix your enum with `k` anyway (or whatever other convention you want to follow) or rename the enum
17:53:29FromDiscord<Phil> (edit) "enum" => "enum-value" | "enum" => "enum-value"

18:00:09FromDiscord<Gabben> But it looks like `overloadableEnums` is just an ad hoc to not implement type inference
18:15:09FromDiscord<eyes> wahoo
18:16:11FromDiscord<eyes> i have a very simple but long-running function I'm trying to run at the same time as the rest of my program
18:16:35FromDiscord<eyes> but i need to be able to stop + restart it
18:17:05FromDiscord<eyes> is there a way to have a shared variable between my main thread and this secondary thread, and write to it from the main thread, telling the second thread to stop?
18:17:20FromDiscord<eyes> alternatively, maybe async programming is the better way to go about this

18:26:36FromDiscord<Phil> In reply to @eyes "alternatively, maybe async programming": Personally async > multithreading, less hassle.
18:26:50FromDiscord<Phil> If you have the option of course
18:27:14FromDiscord<enthus1ast> i think arc/orc made multithreading much more approachable
18:27:57FromDiscord<Phil> Is it now just "run some proc, pass it another proc that shall be executed as a parameter and receive a Future that'll complete when the thread is finished" ?
18:28:50FromDiscord<enthus1ast> mh, it is more like, span threads, if they need stuff from me, get it but make sure you lock the area of access

18:40:43FromDiscord<eyes> In reply to @Isofruit "Personally async > multithreading,": can you describe how i might solve my problem using async?
18:41:08FromDiscord<enthus1ast> @4zv4l\: you do an empty line
18:41:31FromDiscord<eyes> i think i also dont fully understand the difference between async and threading
18:41:51FromDiscord<eyes> async doesnt create a new thread, so how can it allow another job to run in the background?
18:42:01FromDiscord<eyes> thats primarily why my first question concerned threading
18:42:19FromDiscord<enthus1ast> @eyes\: async yields back the control of the thread to a dispatcher
18:42:30FromDiscord<enthus1ast> and the dispatcher let other stuff run
18:42:43FromDiscord<Hourglass [She/Her]> For running a headless firefox instance in Nim, what args should I use? `poUsePath` and `poDaemon`? Usepath is probably good so I can just do `firefox` instead of `/firefox/binary/location`
18:42:53FromDiscord<Hourglass [She/Her]> I don't understand daemons though
18:43:09FromDiscord<Hourglass [She/Her]> I'm creating a CLI client for a website which is why I want this
18:44:16FromDiscord<enthus1ast> @eyes\: when you do threading, you can use a Cond variable so signal another thread that it must run\: https://nim-lang.org/docs/locks.html#Cond
18:44:23FromDiscord<4zv4l> In reply to @enthus1ast "<@329196212282458112>\: you do an": there is not another way ?↵it would take a bunch of newline xD
18:45:12FromDiscord<4zv4l> but alright
18:45:14FromDiscord<4zv4l> gonna try
18:45:42FromDiscord<enthus1ast> sent a code paste, see https://play.nim-lang.org/#ix=4obf
18:46:55FromDiscord<enthus1ast> in async you do not need to take much care, you can just check a variable

19:28:07FromDiscord<eyes> eval

20:17:17FromDiscord<Phil> In reply to @eyes "so I thought that": Async starts becoming relevant if some of the work you do does not depend on your code and you have to wait for somebody else to finish their job
20:18:34FromDiscord<Phil> Typical scenarios are IO where not you write to disk but the OS and you just wait for it to finish (maybe feed it what to write next occasionally), or HTTP requests where you wait for the response
20:18:49FromDiscord<Phil> (edit) "Typical scenarios are IO where not you write to disk but the OS ... and" added "does"
20:28:52FromDiscord<enthus1ast> do we have a seq get `[]` that returns a var ?

20:33:08FromDiscord<auxym> maybe https://nim-lang.org/docs/parsecfg.html would work? if its just key=value pairs
20:33:56FromDiscord<Phil> I mean, personally I'd just write and read JSON because it's a comparatively popular data-format, assuming it's only for machine consumption
20:35:52FromDiscord<Yandall> In reply to @Isofruit "I mean, personally I'd": Now that you say it, I do think it will be better to use json, at least for me
20:36:26FromDiscord<auxym> the .env key=value has become some sort of non-official de facto standard, for better or worse, so I assumed @Yandall might have existing files or something
20:37:58FromDiscord<Yepoleb> In reply to @Yandall "How can I read": you mean just general config variables, right? they do not have to be set as environment variables
20:38:51FromDiscord<Phil> I wonder if some folks still configure with XML on Linux
20:39:05FromDiscord<Yandall> In reply to @Yepoleb "you mean just general": Yeah, there is no need for that
20:39:17FromDiscord<enthus1ast> i must admit i would rather do xml again than yaml
20:39:27FromDiscord<enthus1ast> yaml is terrible....
20:39:55FromDiscord<Phil> For complex scenarios I agree that's true, though it is nice to write in simple cases!↵... which were the only cases I had to deal with yaml so far
20:41:08FromDiscord<enthus1ast> take all the configs out there, i mess up yaml all the time, also for simple stuff, xml (or rather html) i do not mess up that often, could be me of course, but i think its much simpler to parse xml

21:39:00FromDiscord<4zv4l> how do you make some field in an object private ?
21:39:40FromDiscord<Elegantbeef> Fields are by default private
21:51:07FromDiscord<jtv> async is low-rent manual threading where each thread gets to run as long as it wants until it yields 🙂
21:51:25FromDiscord<jtv> Oh whoops, that's old and not relevant anymore, lol, thanks discord
21:52:30PMunch@jtv, important distinction though is that async doesn't actually run stuff at the same time, unless you count stuff you've asked the OS to do and are waiting around for
21:54:37FromDiscord<jtv> Right, it's time slicing the thread you're running in yourself
21:54:50FromDiscord<jtv> Great for GIL-locked environments
21:55:14FromDiscord<jtv> A dubious abstraction elsewhere
21:57:41FromDiscord<Yepoleb> i treat it as an abstraction for select, it works quite well for that
22:01:08PMunchSame
22:02:06FromDiscord<Yepoleb> threads don't scale well for high network loads
22:02:56PMunchThreads don't scale well full stop
22:03:59PMunchI mean for ultimate performance you run one async dispatcher per thread and distribute you work over a couple threads
22:04:30PMunchAssuming you've also got some amount of work with every requests which is worth the communication overhead
22:11:04*PMunch quit (Quit: leaving)
22:48:57FromDiscord<auxym> In reply to @jtv "Great for GIL-locked environments": correction: great for IO-limited things. eg doing "other stuff" while you're waiting for a http reply or DB transaction to complete.

23:25:20FromDiscord<eyes> In reply to @PMunch "@jtv, important distinction though": okay this is what i thought!
23:25:29FromDiscord<eyes> i dont really understand why it is considered threading then
23:27:33FromDiscord<eyes> okay im dying
23:27:39FromDiscord<eyes> is there some way to "kill" a thread?
23:27:59FromDiscord<eyes> I guess just let the thread object go out of scope?
23:35:15FromDiscord<Yepoleb> In reply to @eyes "is there some way": not really, regular termination is often the only option
23:35:28FromDiscord<eyes> interesting
23:35:48FromDiscord<eyes> okay thanks
23:36:31FromDiscord<Yepoleb> common methods are to set a variable that is regularly checked in the inner loop of the thread
23:36:50FromDiscord<Yepoleb> or to close the socket the thread is waiting on for example
23:39:23FromDiscord<eyes> In reply to @Yepoleb "common methods are to": how could you share variables between threads in this way? dont threads in nim have separate heaps
23:43:07FromDiscord<Elegantbeef> Orc/arc do not have seperate heaps
23:43:10FromDiscord<Elegantbeef> You also can manually manage shared heap memory
23:45:34om3gashared heap is the best solution
23:50:53FromDiscord<eyes> beans
23:51:16FromDiscord<eyes> i really dont want to dive into something like that, im only just learning the language
23:51:33FromDiscord<eyes> im still hoping for the async solution to work out
23:58:56FromDiscord<Yepoleb> In reply to @eyes "how could you share": i'd share a pointer
23:59:07FromDiscord<Yepoleb> ideally to an atomic variable
