00:01:42FromDiscord<Anuke> I have a `type` composed of 4 `unit8`s, and I would like to to take up exactly 4 bytes in memory and be cast-able into an int32/float32. Questions:↵1. Is it guaranteed to take up exactly 4 bytes?↵2. Are the fields guaranteed to be in order, e.g. with offsets of 0/1/2/3 bytes? They are on my machine, but I need to be sure it still works that way on others.↵3. Do I need to use the `{.packed.}` pragma here at all?
00:01:49ForumUpdaterBotNew question by Alex Craft: How to avoid modifying function with macros pragma?, see https://stackoverflow.com/questions/67275225/how-to-avoid-modifying-function-with-macros-pragma
00:03:07FromDiscord<ElegantBeef> @Anuke you can do `type TypeName {.size:4.}` to make sure it takes up 4 bytes, which i imagine should disable alignment and similar optimizations
00:03:40FromDiscord<ElegantBeef> Alternatively you can do `type Typename = array[4, byte]` 😄
00:04:54FromDiscord<Anuke> Is the size pragma documented somewhere? I don't see it in the manual
00:06:10FromDiscord<ElegantBeef> Doesnt seem like it's explicitly documented, just used in enum examples
00:08:33FromDiscord<demotomohiro> In reply to @exelotl "yeah I'm working under": It seems defer can be used with --gc:none --os:standalone↵https://wandbox.org/permlink/wLUmfAWB7mUWfnKh
00:09:32FromDiscord<exelotl> oh! this changes everything 👀
00:10:09FromDiscord<exelotl> imma have to advocate for defer now (previously I didn't care about it) xD

08:43:41*Jesin quit (Ping timeout: 240 seconds)
08:44:17FromDiscord<flywind> it has been documented, see https://nim-lang.github.io/Nim/contributing.html#the-cmdgit-stuff-general-commit-rules
08:44:28giacois it possible to write testcases in separate files on procs without exporting them?
08:45:19FromDiscord<flywind> use devel then `import someUnexportModule {.all.}` + importutils module
08:45:28FromDiscord<flywind> use stable just use `include`
08:49:09giacocool! thanks
08:50:09FromGitter<yglukhov> flywind: I see, thanks. How do I backport an already merged commit then?
08:50:31giacoas I need to revert back from using import on all my tests, I now face the problem to detect which exports are actually unused outside the module. Can Nim help me on this task?

10:33:28FromDiscord<carpal> once the ast is typed
10:36:16FromDiscord<haxscramper> The compiler resolves all identifiers as it goes over AST, otherwise it would not be possible to type of `add`'s return value (if there were any)

10:54:05FromDiscord<mlokis> (edit) "manually" => "myself"
10:55:13FromDiscord<flywind> it is high optimized by compiler(a preallocated string and append operations)
10:55:26FromDiscord<haxscramper> I would probably suggest to not rely on compiler optimizations and instead provide more optimal code
10:56:12FromDiscord<flywind> sent a code paste, see https://paste.rs/AfF
10:56:29FromDiscord<flywind> see `genStrConcat`

11:04:32FromDiscord<mlokis> it is messy as f
11:12:32FromDiscord<carpal> In reply to @haxscramper "The compiler resolves all": but function identifiers require types to be resolved, with function overloading add(int, int) if different from add(int, int8)
11:13:02FromDiscord<d4rckh> if i have a long if statement with a bunch of or's and and's how do i go about splitting it on a new line?
11:13:29FromDiscord<carpal> so to resolve the identifier add(1, 2) the compiler needs to kwow the types of 1 and 2, to do this the compiler needs to evaluate the expressions but at this point isn't a mess to mix all in the same phase?
11:14:20FromDiscord<carpal> In reply to @mlokis "anyway i just finished": cool
11:15:21FromDiscord<carpal> In reply to @carpal "so to resolve the": or maybe the compiler could resolve the identifier by replacing the identifier add with the overloads of add
11:15:59FromDiscord<carpal> and then in another phase the compiler will evaluate the parameter expressions to find the rightoverload
11:16:02FromDiscord<carpal> (edit) "rightoverload" => "right overload"
11:16:07FromDiscord<carpal> right?
11:21:08FromDiscord<haxscramper> In reply to @carpal "so to resolve the": It does not need to "evaluate" an expression, it must only resolve it's type
11:21:14FromDiscord<haxscramper> And that's exactly what compiler does
11:25:46FromDiscord<d4rckh> any reason i cant call replace here? https://media.discordapp.net/attachments/371759389889003532/836563767428120596/unknown.png
11:26:53FromDiscord<flywind> do you import `strutils`?

11:27:19FromDiscord<d4rckh> thank you
11:27:29FromDiscord<flywind> np
11:31:43FromDiscord<carpal> In reply to @haxscramper "And that's exactly what": yes, my question was if it does resolve the expression's types during the type resolution
11:32:08FromDiscord<carpal> so in the same phase it also does semantic checks?
11:34:49FromDiscord<haxscramper> Expression type resolution itself is a semantic check if I'm not mistaken about terminology. So yes, it resolves types "in the same phase"

11:51:28FromDiscord<carpal> I mean↵`var x: string = 10`↵this is semantically wrong
11:54:14FromDiscord<carpal> so the compiler resolves the type string, checks if x is doubly declared and if the expression type and the context's type are the same?
11:54:26FromDiscord<carpal> all in the same phase?

11:57:26FromDiscord<carpal> is because of all is done in a one phase that the compiler can't refer to forward declared type or functions?

12:33:47FromDiscord<pointystick> Unaimend, my guess is the matrix is expecting ints but gets enum'd values. Putting '.ord' to turn the enum values into ints lets it compile, not sure if it's correct though
12:34:05FromDiscord<Unaimend> ahh thx
12:34:16FromDiscord<haxscramper> that is correct

12:38:55FromDiscord<carpal> just to learn about it

12:46:34PMunchThis is a bad idea, right? https://github.com/dfdeshom/nimrdkafka/blob/master/example.nim#L50-L53

12:55:59PMunchDefine not working
13:00:38FromDiscord<konsumlamm> using `&` instead of `fmt` should work
13:00:53FromDiscord<konsumlamm> the latter is a raw string literal, so backslash isn't interpreted as escape
13:01:58FromDiscord<konsumlamm> alternatively, `fmt"""..."""` should also work (without backslash)
13:05:17PMunchOh right, I forgot that fmt was a raw string literal
13:13:27FromDiscord<d4rckh> how do i set it so it uses `-d:ssl` when i compile using `nimble build` automatically?
13:14:31FromDiscord<d4rckh> oh nvm i just pass it to the command directly
13:15:54PMunchYou can also add it in the module.nims file

15:33:10FromDiscord<haxscramper> https://nim-lang.org/docs/docgen.html
15:33:50FromDiscord<jtiai> that looks like reference documentation generator.
15:34:14FromDiscord<jtiai> But can you write docs like Python documentation or for example Django docs (all written in Sphinx) with docgen?
15:35:36FromDiscord<haxscramper> What features specifically are you talking about?
15:35:49FromDiscord<haxscramper> nim manual/tutorials etc. are created using `nim doc` too
15:36:29FromDiscord<jtiai> cross referensing pages, titles (different levels) index pages, search, adding images, arbitrary code and so on.
15:37:01FromDiscord<jtiai> <https://docs.djangoproject.com/en/3.2/> docs like that.
15:38:05FromDiscord<haxscramper> It can't do exactly like that, but nim doc also uses RST so you can have most of it's features
15:38:33FromDiscord<haxscramper> like images, titles, "arbitrary code" (whatever this means) and so on

15:41:18FromDiscord<haxscramper> yes it can
15:43:51FromDiscord<jtiai> Looks like it's missing few niceties sphinx provides - like automatic hierarchy and links.
15:44:26FromDiscord<jtiai> Sphinx also has quite simple theming...

15:48:48FromDiscord<jtiai> and there is site "readthedocs.org" which mainly builds sphinx docs...
15:49:06FromDiscord<exelotl> it would work so well because both Sphinx and Nim use RST

15:56:17reversem3!help

15:56:42FromDiscord<flywind> what is asciidoctor?
15:57:01FromDiscord<jtiai> Some Java... crap 😄
15:57:08reversem3nope
15:57:20reversem3its actually written in ruby
15:57:51FromDiscord<haxscramper> the only lightweight markup language that I know of that actually has good tables
15:57:57FromDiscord<haxscramper> And not this ASCII-art madness
15:58:36reversem3@dom96 used it to write his book , I use it all the time for writing docs

15:58:37reversem3lol no not ascii art
15:58:50FromDiscord<haxscramper> yeah
15:59:05FromDiscord<haxscramper> Maybe they actually tried writing two-line table cell or something
15:59:30reversem3its wonderful to use and I also use antora https://antora.org/
16:00:08reversem3Tables are a breeze with asciidoctor

16:01:16reversem3https://asciidoctor.org/docs/asciidoc-writers-guide/#a-new-perspective-on-tables
16:02:56FromDiscord<haxscramper> The only complaint about asciidoctor I have really is that they went with "more character combinations" for tables instead of org-mode approach which is more keyword-heavy. So `#+table:`, `#+row` etc.
16:03:05FromDiscord<haxscramper> `#+caption:`
16:04:08reversem3I used to use org-mode back in the day but switched to JoplinApp cause I can run it anywhere and I can use encryption

17:12:54giacoI'm writing a proc with OR argument type. Inside the proc I'd like to if type A do this, if type B do that. How should I accomplish this? Should I use "case" or "is" or "type" or "typeof" or what?
17:14:36FromDiscord<haxscramper> `when arg is A:`
17:14:47FromDiscord<haxscramper> https://nim-lang.org/docs/manual.html#statements-and-expressions-when-statement
17:17:02giacothanks!
17:17:45*narimiran joined #nim
17:18:51giacoI'm quite confused by this topic. I got that "when" is kinda preprocessor on steroids, but also is and typeof operates at compile time, or not?
17:19:57FromDiscord<haxscramper> yes
17:20:03FromDiscord<haxscramper> `when` evaluates iot
17:20:11FromDiscord<haxscramper> its argument and conditionally compiles block of code
17:20:51FromDiscord<haxscramper> `is` is a type equality check it is evaluated at compile-time
17:21:24FromDiscord<haxscramper> all code that you put in `when` can be put in `if` condition too
17:24:44giacoadding when+is compiles and runs correctly, but replacing when with if doesn't compile anymore
17:25:48reversem3is https://github.com/nim-lang/iup dead ?
17:25:56giacoI think in my case "if" doesn't know that it is dealing with a OR kind of type argument, but "when" does
17:26:03FromDiscord<haxscramper> because `when` conditionally compiles block
17:26:12FromDiscord<haxscramper> `if` compiles both and runs code conditionally
17:29:40giacothis means that ORred arguments actually creates multiple separate procs at compile time, otherwise it wouldn't be able to accept "else" like it is doing now
17:29:54*xet7 quit (Remote host closed the connection)
17:30:13*fredrikhr joined #nim
17:30:34FromDiscord<haxscramper> yes, generics proc generates different implementation for each argument type
17:31:00FromDiscord<haxscramper> I don't think there is any way of doing it differently without going into dynamic typing
17:31:55giacooh no, I prefer them compiled, I'm disintossicating from dynamic typing
17:39:24giacoanother question. I have a template in module A that calls a function of module B, so A imports B. When I call that template from module C I have to import both A and B to compile, not just A. Should I think of templates as something like "include"?
17:44:46*idf quit (Ping timeout: 268 seconds)
17:46:59FromDiscord<haxscramper> I would advise to think of templates as they are described in manual - "A template is a simple form of a macro: It is a simple substitution mechanism that operates on Nim's abstract syntax trees."
17:47:09FromDiscord<haxscramper> Otherwise you could just confuse yourself
17:47:27FromDiscord<haxscramper> And yes, because it is an AST-based substitution you might have to export all necessary symbols
17:48:55FromDiscord<Nisha's alt> Does anyone know if `raylib_now` actually works with Raylib 3.7?

19:42:00FromDiscord<mlokis> do we have a macro that turns nim code into js string?
20:17:22giacoI'm stress testing my web app with 20K GET requests ready to submit as fast as possible (no, not a ddos, both are managed by me :P), so I've created a newAsyncHttpClient and I am looping await client.request and closing the AsyncHttpClient once at the end of the list. It works but is much slower than expected. Both client and server machines are < 5% used cpu and also bandwidth usage is ~30Kbps, so I
20:17:24giacodon't know where the bottleneck is. Any idea?
20:18:31FromDiscord<ElegantBeef> Did you build it as release?
20:18:36giacoyes
20:22:10FromDiscord<ElegantBeef> Well time to use a profiler
20:25:41FromDiscord<ajusa> If you do await client.request doesn't that mean that you're basically just doing all the requests in serial? Like you only send a request at a time?
20:26:44giacoajusa, yes
20:27:41FromDiscord<ajusa> Well what's the average time for a request then? My guess is that latency (assuming that you are running these on different machines) is the problem
20:27:55FromDiscord<ajusa> Otherwise it could be IO, like a database call
20:30:08giacoit makes sense. Let me turn it to parallel async requests
20:32:08giacowill asyncfutures.all make them parallel? (well, async parallel)
20:34:43FromDiscord<ajusa> I think so? You may run out of sockets though, depends on your OS settings
20:42:46FromDiscord<Anuke> Why does nim require --threads:on to use threads? Is there any reason it's not enabled by default on supported platforms?
20:46:52FromDiscord<ElegantBeef> I'll say to not have thread analysis on by default, but that's probably not the reason
20:47:18FromDiscord<ElegantBeef> Certainly not the reason 😄
20:49:34FromDiscord<Nisha's alt> Is there an alternative way to call Python code in Nim?-
20:49:40FromDiscord<Nisha's alt> That does use CFFI?
20:49:54FromDiscord<Nisha's alt> Doesn't↵FFI
20:51:34FromDiscord<Nisha's alt> Probably via RustPython or something
20:51:50FromDiscord<ElegantBeef> And how do you plan on talking to that rust interpreter
20:54:43giacowell, looking at wireshark it seems clear that is is useless to recycle an AsyncHttpClient sending multiple gets using "asyncfutures.all", as they would be serialized anyway
20:55:37giacoI should split the requests into multiple tcp sockets and maybe just serialize a subset of all the requests each
