03:34:27FromDiscord<checkersai> Can I not make a generic distinct type?

03:40:50FromDiscord<Elegant Beef> https://play.nim-lang.org/#ix=3qWz
03:40:58FromDiscord<Elegant Beef> It's a static type so it needs to be `static int`
03:42:14FromDiscord<Elegant Beef> Generics expect types so without it passing in a value causes an error
03:42:30FromDiscord<checkersai> ah that'll do it

04:01:21FromDiscord<Elegant Beef> The reason the second thing doesnt work i think is it's a generic so there is not exact place "borrow" from i think

04:06:40*supakeen joined #nim
04:08:08FromDiscord<Elegant Beef> That's cause it's a typeclass so you cannot borrow that
04:09:37FromDiscord<checkersai> I can't borrow array access operators?
04:09:52FromDiscord<Elegant Beef> Seems it only works for concrete types
04:10:05FromDiscord<checkersai> So I just have to implement a hack where I cast the distinct array into an array?
04:10:12FromDiscord<Elegant Beef> `openarray[T]` isnt concrete
04:10:30FromDiscord<checkersai> sent a code paste, see https://paste.rs/weV
04:11:15FromDiscord<Elegant Beef> Why cast just do `array[N,int](arr)[i]`
04:13:06FromDiscord<Elegant Beef> May also want to checkout `typetraits.distinctBase` think it can be used to make this not need the generic always
04:14:17FromDiscord<checkersai> In reply to @Elegant Beef "Why cast just do": Wouldn't a cast be more efficient?
04:14:35FromDiscord<Elegant Beef> Distinct conversion to base is free
04:14:55FromDiscord<checkersai> ah
04:15:01FromDiscord<Rika> In reply to @checkersai "Wouldn't a cast be": Not necessarily, but it is always more dangerous
04:15:17FromDiscord<Rika> Be more wary of using cast
04:15:26FromDiscord<checkersai> I am generally wary
04:15:38FromDiscord<checkersai> I'm just looking for a way to make a distinct array work

04:29:23fn<Prestige> Yep @Elegant Beef
04:29:36fn<Prestige> seems to be working decently so far, I think
04:30:48fn<Prestige> Maybe I should put in a special case for the FromDiscord bot to not show <FromDiscord>, clutters up the messages a bit
04:59:37FromDiscord<checkersai> y'know I've never seen an ECS implementation in any language that didn't involve hacking around the type system
04:59:49FromDiscord<checkersai> makes me wonder if it's worth the trouble of trying to make my own
05:00:01FromDiscord<Elegant Beef> polymorph is pretty nice

08:02:20FromDiscord<gerwy> Is it as easy as with Windows with only mingw or does i need to deploy docker and compile it there
08:08:16FromDiscord<Varriount> In reply to @Life Sucks "Do anyone know how": Getting the compiler to generate the correct source code is fairly straightforward (it's just a command-line switch). Invoking the C compiler correctly might be a bit more tricky.
08:08:45FromDiscord<Varriount> (edit) "In reply to @Life Sucks "Do anyone know how": Getting the compiler to generate the correct ... source" added "C"
08:09:27FromDiscord<gerwy> that doesn't say to me anything

12:12:15FromDiscord<tomck> Hello, the `alloc` function - is this equivalent to `malloc` in C, or is it doing some garbage collection funny business behind the scenes?
12:12:25FromDiscord<tomck> I just want to manually manage some block of memory, is `alloc` the way to go here
12:16:00FromDiscord<Rika> Yes but there is a kinda better proc to use (`create`)
12:16:20FromDiscord<Rika> Alloc is roughly equivalent but not equal to malloc
12:18:29FromDiscord<tomck> what's the difference between alloc & create
12:22:49FromDiscord<no name fits> In reply to @tomck "what's the difference between": Alloc is a template and create is a proc
12:23:53FromDiscord<no name fits> Also alloc just gives a pointer and create gives a typed pointer

12:33:39FromDiscord<no name fits> So, how would you guys make a GUI app for mobile and Windows, that can easily fill out the contents for a shipping container? It's basically just what the thing is, how many of the thing, what the thing weighs, how much the thing is worth. Like as a big list. And then a container serial number and a from and to. Right now my boss is using paper and then writing it into a word document, but he asked if I could come up with something
12:34:22FromDiscord<zetashift> with Nim? use fidget I'd say
12:34:31FromDiscord<no name fits> I'm still just ass at doing GUI in Nim
12:34:38FromDiscord<no name fits> Fidget? Will look into it
12:34:46FromDiscord<zetashift> you can also do a PWA
12:34:49FromDiscord<zetashift> using karax
12:35:01FromDiscord<zetashift> but I have very to no experience with PWA
12:35:08FromDiscord<zetashift> very little\
12:35:24FromDiscord<no name fits> No server. It has to be native
12:36:11FromDiscord<no name fits> I'll start with fidget I guess, thanks

12:43:07FromDiscord<hamidb80> do you think it's a bug?↵https://play.nim-lang.org/#ix=3qYk
12:44:50PMunchYou find he weirdest bugs..
12:45:22PMunchIt seems to eagerly set point.x to y before it does - point.x
12:45:46PMunchIf you rename the variable on line 6 to something other than point it works
12:45:54FromDiscord<hamidb80> haha, i fear if i open another issue `@timotheecour` kill me
12:45:57PMunchBut I'd say this is definitely a bug
12:46:14FromDiscord<hamidb80> (edit) "haha, i fear if i open another issue `@timotheecour` ... kill" added "would"
12:46:36PMunchSeems like an optimisation that didn't take everything into account
12:46:44FromDiscord<hamidb80> yeah
12:46:59PMunchOh wow, this is going to get annoying fast..
12:47:23PMunchThere is apparently now a bot that bridges this and the old Freenode channel. And whenever I talk here I ping myself in that channel..
12:47:45FromDiscord<hamidb80> what is your opinion about clojure?
12:47:53PMunchI kinda like it
12:47:53FromDiscord<hamidb80> versus Nim
12:48:05PMunchWell, it's a lot less versatile than Nim
12:48:07FromDiscord<vindaar> clojure is awesome
12:48:17FromDiscord<vindaar> and their docs are amazing. But I wouldn't trade Nim for it
12:48:23FromDiscord<hamidb80> do you think learning clojure worth it?
12:48:29PMunchFor example writing a small script in it wouldn't work great since the JVM would have to spin up first
12:48:48PMunchAnd yeah, the Clojure docs are amazing
12:48:58FromDiscord<zetashift> THere is babashka nowadays for that
12:49:13PMunchI'd say it's worth it if for nothing else you'll learn a functional language
12:49:19FromDiscord<vindaar> Personally I think it is worth learning. Or any lisp really (yea, yeah, that old comment). But clojure in particular because of its functional focus
12:49:41FromDiscord<zetashift> I'm learning Lisp by configuring my neovim with Fennel
12:49:49FromDiscord<hamidb80> ok, thank you both
12:50:19PMunchI can greatly recommend this resource for learning Clojure: https://www.braveclojure.com/introduction/
12:51:32FromDiscord<zetashift> +1 I've read a few pages it's solid↵(<@709044657232936960_=50=4dunch=5b=49=52=43=5d>)
12:51:52FromDiscord<hamidb80> does interactive REPL in clojure help much ?
12:52:04FromDiscord<hamidb80> how often do you use ut?
12:52:06FromDiscord<hamidb80> (edit) "ut?" => "it?"
12:52:51PMunchCan't remember, it's been ages since I tried Clojure
12:53:04FromDiscord<vindaar> yup, also a thumbs up from me for clojure for the brave and true. Own the physical book as well. I also own the joy of clojure, but haven't read much from it so far 🙈
12:53:15PMunchIt's actually a roundabout way how I found Nim
12:53:35FromDiscord<vindaar> In the last \~2 years not at all really. Somewhat of a similar story as PMunch's for me↵(@hamidb80)
12:54:28FromDiscord<vindaar> I do keep thinking about using it again for something just for fun though
12:55:00FromDiscord<hamidb80> In reply to @hamidb80 "do you think it's": i wanna open an issue for it, what title do you suggest?
12:56:22FromDiscord<System64 ~ Flandre Scarlet> Is there simple audio framework / lib with callback proc please?
12:59:43fn<ForumUpdaterBot> New post on r/nim by richardd08: Does the Nim Jetbrains plugin not work for anyone else? It keeps telling me that the Nim executable is not added to PATH even though it is., see https://reddit.com/r/nim/comments/o70d9d/does_the_nim_jetbrains_plugin_not_work_for_anyone/
13:00:54FromDiscord<haxscramper> In reply to @System64 "Is there simple audio": No need to spam a question, try to formulate the requirements better. I don't have the slightest idea what you are trying to find.
13:01:44fn<ForumUpdaterBot> New post on r/nim by miran1: NimConf 2021 (June 26th), see https://reddit.com/r/nim/comments/o70eg0/nimconf_2021_june_26th/
13:02:10FromDiscord<zetashift> Even in other languages like Scala or Elixir I don't really use their REPL that much, so people consider it a serious must-have for fast prototyping though
13:05:38FromDiscord<System64 ~ Flandre Scarlet> In reply to @haxscramper "No need to spam": sorry, I'll try to formulate it in a better way↵I'm looking for an audio lib, easy to use which have a callback function↵I hope it's formulated in a better way
13:06:03FromDiscord<haxscramper> ...
13:06:24PMunchThat's the same way, just with slightly more words..
13:07:06PMunchWhen do you want it to call your callback?
13:07:09FromDiscord<haxscramper> Callback function for what? Just any random lib that has a callback functions? Can you describe what do you want it to do, or how you want to use it (e.g. what you are working on and what you are trying to figure out)?
13:07:18PMunchWhat kind of audio, what platform(s)
13:07:31FromDiscord<haxscramper> Don't be afraid to provide more info
13:07:36FromDiscord<System64 ~ Flandre Scarlet> crossplatform, audio buffer
13:08:03PMunchHave you had a look here? https://nimble.directory/search?query=audio
13:08:14FromDiscord<vindaar> [haxscramper](https://matrix.to/#/@haxscramper:matrix.org)\: just saw your comment about the pretty printing of types things. Is your `pprint` thing in your `hpprint`? It looks like something I want 🙃

13:10:30FromDiscord<haxscramper> But I'm currently writing v2.0 that would be included with `hmisc` (because I don't want it to be a separate package since I do have some issues with dependencies)
13:10:49FromDiscord<vindaar> ok, cool!
13:11:08FromDiscord<haxscramper> v2.0 would be full rewrite using google's global layout optimization, 256-color styling support etc
13:11:55FromDiscord<haxscramper> Well, it is mostly done, since I don't have to write layouter and most of the `T` -\> `PPrintTree` conversion is already implemented
13:12:32FromDiscord<vindaar> sounds great
13:14:32FromDiscord<haxscramper> But hpprint is fully usable even now, I just want to have a cleaner reimplementation and some additional features
13:14:42FromDiscord<haxscramper> And cut out some things I didn't need
13:18:09FromDiscord<vindaar> I'll give it a try. Will get back to you if I stumble somewhere

13:24:26FromDiscord<gerwy> like using `;` etc.
13:29:19FromDiscord<vindaar> just put the if statement into parenthesis and and it should work in one line
13:29:20FromDiscord<vindaar> not sure why you'd want that of course

13:47:05FromDiscord<haxscramper> Does anyone have a quick example on how to use `gprof` with nim? I've searched for mentions, and I've seen several people (like leorize, arnetheduck and Araq saying that it works and could/should be used)?
13:47:45FromDiscord<haxscramper> I've added `-pg` options to both linker and parser and nim (checked whether they were correctly added in `.json` compilation script)
13:48:11FromDiscord<haxscramper> But after running the profiled application it should supposedly generate `gmon.out`, which does not happen
13:49:08FromDiscord<leorize> it does happen, but remember that the profile data is stored on the same folder as the C files↵(@haxscramper)

13:52:08FromDiscord<leorize> oh wait that's gcov
13:52:11FromDiscord<haxscramper> Thanks, found it. Though it was not in the C files directory in in the directory from where I was running compiler
13:52:17FromDiscord<haxscramper> not where application was stored
13:52:21FromDiscord<leorize> lol
13:52:27FromDiscord<leorize> yea, gcc is weird
13:52:34FromDiscord<haxscramper> Now I feel stupid for not just doing `fd gmon.out`
13:53:05FromDiscord<haxscramper> is `nimFrame` using `10.65` of the time normal?
13:53:20FromDiscord<haxscramper> It means i have a function call overhead, correct?
13:53:31FromDiscord<haxscramper> a lot of function call overhead
13:53:34FromDiscord<leorize> disable stacktrace
13:54:02FromDiscord<leorize> nimFrame is inserted by `--stacktrace:on` and prevents inlining
13:54:59FromDiscord<haxscramper> Good, `1337ms` down to `530ms`
13:55:16FromDiscord<leorize> lol, 1337ms
13:55:49FromDiscord<haxscramper> Any options for function name demangling and getting positional information?
13:56:10FromDiscord<leorize> read the .ndi files
13:56:41FromDiscord<leorize> that's the only option til Araq implements actual name mangling for Nim
13:57:12FromDiscord<leorize> for positional \`--linedir\:on\`\`
13:58:41fn<georgia> hi all
13:58:44FromDiscord<haxscramper> to get `.ndi` I have to enable `--debugger:native` as well
13:58:54FromDiscord<haxscramper> Alright, this is good enough, I can work with that
14:00:00FromDiscord<haxscramper> I assume that means getting function signatures is not possible?
14:00:32FromDiscord<leorize> ndi should get you where they are at
14:00:33FromDiscord<haxscramper> Nim function signatures
14:00:42FromDiscord<leorize> but it's inconvenient, right
14:02:25FromDiscord<haxscramper> Does `nim-gdb.py` demangle things differently somehow?
14:03:18FromDiscord<haxscramper> From what I can tell after briefly looking it just matches strings all over the place with regex and reformats for better appearance?
14:03:27FromDiscord<haxscramper> Or there is more going on and I should look deeper into this?
14:04:13FromDiscord<leorize> it doesn't the last time I checked, but maybe [saem](https://matrix.to/#/@saem:matrix.org) knows more

14:27:50FromDiscord<vindaar> you can write a macro for it if you really want it. But it's not really a good idea to abuse that for this
14:29:41FromDiscord<vindaar> wrote this a couple of years ago, because someone asked the same thing https://gist.github.com/Vindaar/b008cf68819bb87e497b2c24ba84b6a1
14:30:02FromDiscord<Smarc> Thanks for your help guys!
14:30:12FromDiscord<Smarc> Is it somehow bad practice or why should I not do it anyway?
14:30:55*PMunch quit (Quit: leaving)
14:31:02FromDiscord<vindaar> I mean you shouldn't use a macro just because you want to avoid an `and` or similar in my opinion
14:31:40FromDiscord<vindaar> macros are great, but you can easily break them, add quite a few lines of code for barely any win, make you have to put the expression into some macro scope etc
14:33:57FromDiscord<Rika> its much work for little gain
14:37:36FromDiscord<haxscramper> In this case you can implement `a OP b OP c` using TRM macros
14:38:15FromDiscord<haxscramper> So no new scope
14:39:31FromDiscord<zetashift> Maybe this is one of these cases that just because you can it doesn't mean you should :P
14:40:17FromDiscord<Rika> maybe? it pretty much is
14:42:32FromDiscord<vindaar> oh, good point! I've still never used term rewriting macros. Always forget about them 😁
14:44:02FromDiscord<haxscramper> I also don't use them
14:44:19*max22- joined #nim
14:44:21FromDiscord<haxscramper> I don't think I've seen anyone really use them
14:45:02FromDiscord<haxscramper> But the idea of TRM macros is absolutely great, there just some hiccups in the implementation, and you need to be very careful with transformations
14:45:53*al1ranger joined #nim
14:46:17FromDiscord<Rika> theyre great but its kinda scary to think about isnt it? its very very very implicit, might send a lot of people for a loop trying to find whats wrong with their code
14:46:25FromDiscord<Rika> just to realise its because of a TRM
14:49:03FromDiscord<haxscramper> Implicit code transformations are not great, but there are other applications, for example I showed https://forum.nim-lang.org/t/7837 example of how one can implement user-defined warnings
14:50:20FromDiscord<hugogranstrom> TRM as of now is basically useless as well as it has an upper limit for how many substitutions it makes in the code 😛
14:50:37*al1ranger quit (Remote host closed the connection)
14:54:12FromDiscord<haxscramper> You mean per-invocation limit or there is a global one?
14:54:32FromDiscord<haxscramper> Biggest issue is that `{.noRewrite.}` is broken
14:54:47FromDiscord<haxscramper> Everything else is tolerable
14:55:05FromDiscord<haxscramper> But `noRewrite` is a showstopper for the most applications

16:16:55FromDiscord<arne> if you want to break on function `foo` but it is called foo123abcdef instead, you can use `rbreak foo`

17:08:56FromDiscord<haxscramper> vindaar\: btw if you have any requests for features, on pretty-printing since I'm currently rewriting things and it would be pretty easy to account for additional features
17:09:18FromDiscord<haxscramper> While it might be harder to do after I finish main implementation parts
17:12:11FromDiscord<vindaar> I fully understand the sentiment, but from the top of my head...↵Well, I don't know what features are there in the first place right now. I mainly want to be able to print all types (including refs, so that printing of `NimNodes` works fine without `repr`). And what's already there\: multiple colors + smart indentation

18:20:14FromDiscord<Alea> Alright why is there no consistency between != And not?
18:20:26FromDiscord<Alea> Is ! used for something else?
18:22:54FromDiscord<haxscramper> `!=` is a template that expands to `not(a == b)`
18:23:16FromDiscord<haxscramper> https://github.com/nim-lang/Nim/blob/version-1-4/lib/system/comparisons.nim#L130
18:23:27FromDiscord<Alea> Hmm
18:23:46FromDiscord<Alea> So I could make my own template that extends to not(a)
18:23:57FromDiscord<Alea> (edit) "extends" => "expands"
18:24:26FromDiscord<haxscramper> You mean `template !`?
18:24:49FromDiscord<Alea> Yes
18:24:53FromDiscord<Alea> Or is that already in use
18:25:42FromDiscord<haxscramper> I don't think it is already in use, but I would advise you to not define `untyped` templates for such basic operators because at some point it will clash with other proc
18:26:12FromDiscord<haxscramper> For example some library might implement `!`, and IIRC `untyped` template always wins in overload resolution, so it would be problematic
18:26:20FromDiscord<haxscramper> To use this library
18:26:43FromDiscord<haxscramper> Also, nim mostly uses keywords for logic, so better to stick with `not/and/or/xor` etc.

19:07:15kasperk81dom96: it's a unit test run of nim-lang/nim repo. it doesn't seem like an installation problem, as thousand of other tests are passing. it is specific to how this test is set up.

19:15:00petrjkasperk81: it does look like some linker flag is missing in this test setup. if most programs and tests are working fine, then this test requires some update https://github.com/nim-lang/Nim/blob/devel/tests/arc/trepr.nim (but i'm not sure how the typical fix for the linker/include errors look like in nim).
19:17:47kasperk81same, i read that test code a few times, but nothing is immediately jumping at me. someone familiar with nim internals might be able to spot the issue.

21:26:29FromDiscord<treeform> In the nim type system can you say all types but `ref` types but `object` type? Like `ref array`, `ref string` `ref enum` but not ref object?
21:29:29FromDiscord<clyybber> `ref[not object]`
21:29:31FromDiscord<treeform> this appears to work `type NotObject = tuple | enum | proc | ptr | distinct | array | set | seq` not sure if there is a better way

21:44:15FromDiscord<Ricky Spanish> how do you check length/size of table?
21:46:37FromDiscord<treeform> In reply to @Ricky Spanish "how do you check": `table.len()`
21:47:03FromDiscord<treeform> Is it just me or is `Option` is basically same thing as a `ref` ?
21:47:27FromDiscord<vindaar> huh?↵(@treeform)
21:47:53FromDiscord<vindaar> if you abuse a ref such that `nil` is `none` then i suppose it's a poor man's `Option`?
21:48:53FromDiscord<treeform> a simpler option? no imports, nil easier to work with?
21:48:57FromDiscord<checkersai> In reply to @treeform "Is it just me": No?
21:49:12FromDiscord<vindaar> reference semantics vs. value semantics, access give SIGSEGV vs. raises an exception etc
21:49:41FromDiscord<dom96> You can't modify the value that's inside an Option
21:49:44FromDiscord<vindaar> they might share similarities, but their intention / use case is very different
21:51:32FromDiscord<checkersai> In reply to @dom96 "You can't modify the": Yes you can
21:52:48FromDiscord<dom96> oh you're right, there is a `get` that returns a `var`
21:54:24FromDiscord<treeform> https://media.discordapp.net/attachments/371759389889003532/857740465239097394/unknown.png
21:54:37FromDiscord<treeform> Nearly identical API
21:56:13FromDiscord<vindaar> except that the `Option` case is↵● clearer to the reader↵● you don't have to deal with `nil` checks (which are now ambiguous between pointer types from a wrapped lib for instance and this)↵● you still have reference semantics when copying the object
21:56:18FromDiscord<checkersai> Options are safer because they do more to force you to check
21:56:25FromDiscord<checkersai> Its purpose is clearer
21:56:33FromDiscord<vindaar> and if you ever forget to check if it's nil you get an exception in the `Option` case
21:56:42FromDiscord<checkersai> And an Option[int] is allocated on the stack
22:00:05FromDiscord<checkersai> Side note, I'm not a big fan of how you can ommit parenthesis when calling functions with `x.f`↵Like with `x.get` vs `x.get()`
22:00:42FromDiscord<checkersai> Makes it easy to confuse between field access and calling a function
22:01:06FromDiscord<checkersai> (edit) "field" => "variable"
22:01:33FromDiscord<treeform> but also allows you to start with a field and promote it to a getter/setter later on.
22:02:04FromDiscord<checkersai> If it looks like a field it should be a field and if it's a function it should look like a function imo
22:02:16FromDiscord<checkersai> C# does this too and I don't like it there either
22:02:46FromDiscord<gerwy> then make it look like a function , parenthesis are optional, so you can put them if you prefer it
22:03:34FromDiscord<checkersai> But others might not which makes looking at their source code a bit harder
22:06:00FromDiscord<dom96> `obj.field = 42` is this a function call? 🙂
22:07:38FromDiscord<treeform> ^ that's a macro for sure
22:09:02FromDiscord<checkersai> In reply to @dom96 "`obj.field = 42` is": It could be
22:09:53FromDiscord<checkersai> Since functions can return vars↵`someOption.get() = 42` is valid
22:11:08FromDiscord<dom96> not only that, Nim allows you to define setters: https://nim-lang.org/docs/manual.html#procedures-properties

23:30:42FromDiscord<checkersai> Well Araq did model many parts of the language after Pascal
23:31:02FromDiscord<checkersai> And he was a Pascal programmer
