00:16:04FromDiscord<luteva> it is just horrible, when you try/want/need to wrap it....
00:20:25FromDiscord<luteva> it took me days to get a simple "press this"-QButton working with the qt lib wrapped in nim.
00:23:14FromDiscord<Prestige> It's a shame it's such a pain, makes me not want to work with any c++ related libraries
00:24:17FromDiscord<Elegantbeef> Make C apis great again
00:24:59FromDiscord<Prestige> even that's not fun tbh
00:25:07FromDiscord<Prestige> unless futhark can just do it for you
00:27:14FromDiscord<Elegantbeef> It can just do it for you
00:27:15FromDiscord<Elegantbeef> I mean you have to wrap it after for idiomatic feeling
00:27:15FromDiscord<Elegantbeef> But you cant get better than https://github.com/beef331/miniaudio/blob/master/src/miniaudio.nim#L4-L18
00:27:15FromDiscord<Elegantbeef> The entire C api jusst imported with like 10 loc
00:27:17FromDiscord<Elegantbeef> It's like Zig levels of magic
00:29:25FromDiscord<luteva> In reply to @Avahe "It's a shame it's": same for me. it is not ment to be wrapped. So throw it away. you also have this "unknown memory layout"-problem for inheritance in c++.
00:29:57FromDiscord<Elegantbeef> Yea i mean people try to shoehorn nim into existing game engines from like 20 years ago
00:30:41FromDiscord<Elegantbeef> Like it's technically possible but it's a fools errand
00:36:15FromDiscord<luteva> there are of course c++ libraries that are ment to be integrated into other languages, like xapian e.g.↵if you find a list of at leat a handful language bindings on the projects page, then chances are that it won't be too hard 🙂
00:39:43FromDiscord<Elegantbeef> A lot of libraries do have a C-api so it makes life better
00:40:04FromDiscord<Elegantbeef> There arent many languages that can actually interop with C++ like Nim/D can so it's a understandable hell

06:48:53FromDiscord<Elegantbeef> > There's 3 languages in the same class. Julia, Nim and Crystal.↵Man hackernews makes me laugh
06:50:47FromDiscord<Prestige> Yeah, thought that was an odd statement
06:51:01FromDiscord<Prestige> I thought they were going to say nim, rust, and go. Lol
06:51:26FromDiscord<Elegantbeef> Also @Phil you've misrepresented compile time procedures, any procedure that is just nim code and doesnt rely on lowlevel operations are compile time!
06:51:46FromDiscord<Rika> can be compile time
06:52:04FromDiscord<Elegantbeef> Yea what you said
06:53:23FromDiscord<Elegantbeef> Yea prestige it's an odd statement nim and crystal are both system languages iirc so it's not a bad comparison, but julia is a super odd one
06:54:07FromDiscord<Elegantbeef> It's a weird scripting language but not but is
06:56:09FromDiscord<Rika> But not but is?
06:56:22FromDiscord<Elegantbeef> Yea you get it
07:01:32FromDiscord<Rika> Yeah I don’t
07:02:19FromDiscord<Elegantbeef> it's kinda like C# in that it's not low level but it's not super high level, it can be AOT'd but it can also be JIT'd
07:02:51FromDiscord<jmgomez> hey guys, is there a way to invoke a macro in runtime? I dont want to change the actual ast code but to emit nim code, from data that I get at runtime, into a file (via repr). I know I could save it in a intermediate format (i.e. json) and read it at compile time, but I wonder if I can save that extra step
07:03:00FromDiscord<Elegantbeef> It also uses multiple dispatch is it's fucking crazy
07:03:18FromDiscord<Elegantbeef> You could embed the NimVM and use that
07:03:28FromDiscord<Rika> I still don’t understand multiple dispatch tbh
07:04:07FromDiscord<Elegantbeef> You use runtime information of every parameter to reason which procedure to call instead of just the first parameter
07:04:53FromDiscord<Rika> It doesn’t sound too bad
07:05:02FromDiscord<Rika> Caveats are? Other than performance
07:05:12FromDiscord<Elegantbeef> So in the case of collision with two shapes `circle` and `square` you can have `collide(circle, circle)` `collide(circle, square)` `collide(square, circle)` `collide(square, square)`
07:05:19FromDiscord<Elegantbeef> It's tremendously difficult to reason what's being called
07:05:21FromDiscord<jmgomez> In reply to @Elegantbeef "You could embed the": is that referring to my question? if so, any direction on how to do it?
07:05:35FromDiscord<Elegantbeef> Nimscripter will be the easiest way
07:05:53FromDiscord<Elegantbeef> https://github.com/beef331/nimscripter/tree/master/examples/macrorepl i have an example similar to what you're doing
07:06:17FromDiscord<jmgomez> cool, thank you!
07:06:33FromDiscord<Elegantbeef> For each new type you add you add yet another possible overload to a method call
07:06:56FromDiscord<Elegantbeef> So multipile dispatch is notorious difficult to reason about
07:09:05FromDiscord<jmgomez> talking about dispatchers, its mentioned that nim dispatcher works with ref objects, which makes sense. Any chance they do work with ptr too?
07:09:23FromDiscord<Elegantbeef> Methods or static dispatch?
07:09:41FromDiscord<jmgomez> methods
07:09:47FromDiscord<Elegantbeef> For native nim objects the type information is there so i dont see why not
07:11:03FromDiscord<jmgomez> I mean, for bound ptrs
07:11:24FromDiscord<d4rckh> what's nimscript?
07:11:27FromDiscord<Elegantbeef> You mean imported objects?
07:11:39FromDiscord<jmgomez> yes
07:11:53FromDiscord<Elegantbeef> No it will not it lacks the type information
07:12:05FromDiscord<jmgomez> no way you can provide it?
07:12:05FromDiscord<Elegantbeef> Nimscript is a subset of Nim that runs on the NimVm and is used for static evaluation and macros
07:12:21FromDiscord<Elegantbeef> No it's the first field of a type a pointer to the Nim type information
07:12:23FromDiscord<Prestige> Is it still very slow?
07:12:36FromDiscord<Elegantbeef> I dont know how slow it is
07:12:41FromDiscord<Elegantbeef> I've never really benchmarked it
07:12:52FromDiscord<Rika> Most people say it’s “at least faster than Python”
07:13:03FromDiscord<Elegantbeef> Dont know if it's true stiiill
07:13:21FromDiscord<Prestige> I heard it's slower than python by a good bit
07:13:44FromDiscord<Prestige> but I heard that like maybe 8 months ago
07:13:55FromDiscord<Elegantbeef> I dont think it's speed is really a concern
07:14:26FromDiscord<Prestige> Yeah true
07:14:34FromDiscord<Prestige> it's not like people are using python for speed anyway
07:14:52FromDiscord<Elegantbeef> I mean i'm very much of the view "use wasm if you want to script a program from your language of choice"
07:15:07FromDiscord<Elegantbeef> Nimscript is really good for quickly interoping with a program or for things like a config
07:16:04FromDiscord<Prestige> I don't really know why python is used so much other than its historical usage
07:16:40FromDiscord<Rika> Because it’s easy in both syntax and batteries included
07:17:22FromDiscord<Prestige> is it really batteries included? It seems to have a lot of libraries people could use, but I thought they're 3rd party
07:17:41FromDiscord<Prestige> I could see (compiled) nim actually being a great replacement
07:18:01FromDiscord<Rika> The standard library is sizeable so yes
07:18:18FromDiscord<Rika> I don’t see Nim as a replacement until the ecosystem expands in size xd
07:18:26FromDiscord<Elegantbeef> the downside is nim isnt hacker friendly
07:18:55FromDiscord<Prestige> What does that mean?
07:19:21FromDiscord<Elegantbeef> You can open up python code with any text editor change nothing and have it run on your system without having to get any thing on most distros
07:19:39FromDiscord<Elegantbeef> "change nothing" ah yes brain that makes sense
07:19:42FromDiscord<Prestige> ah, yeah. Systems coming with python helps
07:19:42FromDiscord<Elegantbeef> change something
07:20:54FromDiscord<Rika> Well it’s either static linking (ala Go) or VM (ala a lot of other languages out there)
07:21:09*xet7 quit (Remote host closed the connection)
07:21:21FromDiscord<Rika> And the first doesn’t even help for other operating systems

07:26:12FromDiscord<Prestige> the more I think about it, the more I like static linking
07:27:17FromDiscord<Elegantbeef> With modern internet and storage it's less of an issue that prior but it does have the downside of security are more annoying
07:28:00FromDiscord<Rika> I like having both options available

07:47:03FromDiscord<soundmodel> (edit) "Anyone have theory as to why there are so many langs that are trying something similar to Nim, but ... possibly" added "are"
07:47:13FromDiscord<Elegantbeef> There have always been many languages, just now there are a bunch more programmers that want specific things
07:47:15FromDiscord<Rika> People are afraid of change
07:47:16FromDiscord<soundmodel> (edit) "Anyone have theory as to why there are so many langs that are trying something similar to Nim, but ... are" added "that"
07:47:43FromDiscord<Rika> Also risk and effort of changing things
07:47:59FromDiscord<Rika> Especially true in enterprise of course
07:48:45FromDiscord<soundmodel> But I mean, considering Nim makes e.g. D, Vala, Zig and V totally interesting to me
07:49:30FromDiscord<Prestige> Funny enough I found Nim on accident. Was trying to look up Zig but forgot the name, ended up finding nim instead and dove in
07:49:56FromDiscord<Elegantbeef> Comically is i think that's a common occurrence for people to confuse zig for nim
07:49:57FromDiscord<soundmodel> (edit) "interesting" => "uninteresting"
07:50:23FromDiscord<Elegantbeef> Different strokes for different folks and all that↵(@soundmodel)
07:50:36FromDiscord<Elegantbeef> There is a reason so many languages exist the developers/designers think they can do better
07:50:42FromDiscord<Prestige> I looked up a list of programming languages with 3 letters, cuz that's all I could remember
07:50:50FromDiscord<soundmodel> In reply to @Elegantbeef "Different strokes for different": It should say uninteresting
07:51:03FromDiscord<soundmodel> (edit) "uninteresting" => "uninteresting, I typoed"
07:51:10FromDiscord<Elegantbeef> I know
07:51:35FromDiscord<Elegantbeef> Oh odd the reply doesnt show the edit
07:53:40FromDiscord<soundmodel> Zig and D seemed to have more authentic C experience, but Nim's c interop seems to achieve essentially the same goals
07:53:56FromDiscord<soundmodel> (edit) "c" => "C"
07:55:20FromDiscord<locria> How to run a command when installing nim library
07:55:38FromDiscord<Elegantbeef> Well Odin and Zig are the most C-like
07:55:40FromDiscord<locria> I need to run custom build script when installing nim library with `nimble install`
07:56:34FromDiscord<soundmodel> C-likeness is not even a good goals, interfacing with C is
07:56:51FromDiscord<soundmodel> (edit) "goals," => "goal,"
07:57:07FromDiscord<locria> Interfacing with C++ is hell for anyone

07:57:44FromDiscord<Elegantbeef> It might
07:59:35FromDiscord<locria> Is there `cd` in Nim?

08:13:29FromDiscord<S3cur3Th1sSh1t> Hi Guys,↵I'm trying to use special characters in a Nim DLL for the export function, but they are never escaped correctly. Do you have some ideas on how to escape it?↵↵`proc funcname(): BOOL {.stdcall,exportc: "^/??@".} =`
08:14:58FromDiscord<demotomohiro> At least, it should be valid C function name, isn't it?
08:15:01FromDiscord<S3cur3Th1sSh1t> sent a code paste, see https://play.nim-lang.org/#ix=41gA
08:15:52FromDiscord<S3cur3Th1sSh1t> Well I found some DLL's using function names with theese characters, so it should be possible https://media.discordapp.net/attachments/371759389889003532/991980377252044830/unknown.png
08:16:39FromDiscord<S3cur3Th1sSh1t> `?` can be escaped with `qmark` for example, but this is not done when using `exportc`. Also opened an issue about that https://github.com/nim-lang/Nim/issues/19945
08:17:21FromDiscord<Elegantbeef> Are you attempting to escape `?`?
08:17:42FromDiscord<xflywind> write a macro to escape exported names.
08:19:02FromDiscord<demotomohiro> These function names looks like unmangled C++ function name.
08:22:25FromDiscord<apahl> Hi, is someone aware of a Nim library that can read TIFF files and allows basic pixel manipulation?
08:24:07FromDiscord<S3cur3Th1sSh1t> In reply to @demotomohiro "These function names looks": Possible. I don't know to be honest. But I'm looking for a way to export functions like those.↵ This screenshot shows, that it's done correctly without `ecportc`. So I'm assuming, that this should also be possible when using it. https://media.discordapp.net/attachments/371759389889003532/991982451989676062/unknown.png
08:26:08FromDiscord<locria> In reply to @S3cur3Th1sSh1t "Possible. I don't know": `{.extern: "namehere", exportc.}`
08:26:22FromDiscord<locria> `{.extern: "namehere", exportcpp.}`
08:27:04FromDiscord<locria> They generate C source code , so you can't use invalid C-identifier
08:28:27FromDiscord<demotomohiro> In reply to @apahl "Hi, is someone aware": https://nimble.directory/search?query=image
08:29:31FromDiscord<locria> You should ask the C linker to use another name
08:29:56FromDiscord<xflywind> In reply to @S3cur3Th1sSh1t "Possible. I don't know": Write your own escape macros.
08:30:11FromDiscord<xflywind> sent a code paste, see https://play.nim-lang.org/#ix=41gF
08:30:33FromDiscord<S3cur3Th1sSh1t> In reply to @locria "You should ask the": Some link on how to do that?
08:30:49FromDiscord<locria> don't know
08:31:05FromDiscord<demotomohiro> Nim automatically convert function name to valid c-identifier when you declare proc `^/??@"`. But `exportc: "^/??@"` asks Nim to generate C function with specified name.
08:31:06FromDiscord<apahl> In reply to @demotomohiro "https://nimble.directory/search?query=image": Yes, thank you, I did that. But AFAIK none of those projects can read TIFF files.
08:32:08FromDiscord<locria> search for how to make a C function use a different name in symbol table
08:32:57FromDiscord<demotomohiro> In reply to @apahl "Yes, thank you, I": There is a plan to add TIFF support to pixie: https://github.com/treeform/pixie/issues/429
08:33:44FromDiscord<apahl> Oh, that is neat. I will follow the issue. Thank you.
08:40:53FromDiscord<Phil> In reply to @Elegantbeef "Also <@180601887916163073> you've misrepresented": I don't think I'm understanding this one.↵So the compiler infers at time whether he can just automatically make a proc purely compile-time without having a compile-time-pragma ?
08:41:42FromDiscord<Phil> Or is that where the "can be compiletime" comment from Rika comes in and you do need the compile-time-pragma?↵At which point I'm just confused
08:46:28FromDiscord<demotomohiro> https://wandbox.org/permlink/eXc5OpeqohBO6Q5p↵In this code, proc `foo` can be used at both runtime and compile time.
08:51:38FromDiscord<locria> Can I use pixie with OpenGL?
09:00:42FromDiscord<demotomohiro> This code uses pixie with OpenGL: https://gist.github.com/demotomohiro/6ae8baf1e40fffae3858c2ff01a8d241
09:02:34FromDiscord<demotomohiro> It uses `glDrawPixels` just for simplicity. It is a deprecated OpenGL function.

09:27:36FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=41gO
09:28:45FromDiscord<jmgomez> yeah, I know, but I need it to be uint64
09:28:46FromDiscord<Elegantbeef> But eitherway you should be able to do `name(uint64(ord(a)) or uint64(ord(a)))`
09:28:57FromDiscord<jmgomez> okay!
09:29:02FromDiscord<Elegantbeef> Why does it need to be though?
09:29:18FromDiscord<jmgomez> because that's the size of their counterpart on cpp
09:29:28FromDiscord<Elegantbeef> It's fixed size so the C compiler doesnt care if you pass it to as uint64
09:30:23FromDiscord<jmgomez> and how it will be holding the values if they are large?
09:30:44FromDiscord<Elegantbeef> The issue is if you need specific values for the enuum
09:31:06FromDiscord<Elegantbeef> If it's just 0..63 bits it's fine but if you have flags with more than 1 bit you have issues
09:31:07FromDiscord<jmgomez> yeah, I do
09:31:57FromDiscord<Elegantbeef> Ah i guess with larger sets it does need a typecast
09:32:33FromDiscord<jmgomez> In reply to @Elegantbeef "But eitherway you should": this seemed to work, thanks!
09:35:48FromDiscord<Elegantbeef> I guess you dont need to convert it into a uint64 if you're just doing a bitwise op
09:48:50FromDiscord<arnetheduck> In reply to @jmgomez "if you try to": keep in mind that nim `enum`:s are not the same as `c` enums - if you have something enum-like in C, you're likely better off with `const` in nim to represent it, using the same type as `c` (`uint64`) in your case
09:49:29FromDiscord<enthus1ast> this is what always annoys me when dealing with c apis↵(@arnetheduck)
09:50:31FromDiscord<arnetheduck> well, there's many c features that don't have an equivalent in nim, and vice versa - this is just one more, though I guess the fact that they share keyword makes it worse
09:50:52FromDiscord<jmgomez> Does that applies to C++ too?
09:51:11FromDiscord<jmgomez> I mean, dont know in c but in cpp you can specify the underlaying type
09:52:06FromDiscord<arnetheduck> it applies even more strongly to C++ 😉
09:53:21FromDiscord<arnetheduck> it's not the underlying type that is the problem really, but rather the surrounding semantics (handling of holes, multiple values with the same ordinal, random `Defect` on the nim side crashing your application etc)
09:54:06FromDiscord<retkid> arrayfire's nim page is archived
09:54:07FromDiscord<retkid> is uh
09:54:15FromDiscord<retkid> this for any reason i should be worried about

11:19:50FromDiscord<rb3.nim> Damn, it looks like it uses FFI, so it can't run in the VM
11:21:40FromDiscord<demotomohiro> Maybe you can write a nim code that calls `osproc.execProcesses` and run that code from your nimscript.
11:22:32FromDiscord<rb3.nim> Ya that was gonna be my "hack". Nimscript will build the thing that builds the other thing 😂 was hoping it was gonna be simpler
11:22:39FromDiscord<rb3.nim> Thanks!
12:18:10FromDiscord<Forest> Hm, I'm planning on implementing a JVM backend for Nim, but I'm wondering on some of the difficulties I'll encounter while doing this
12:18:51FromDiscord<Forest> I'm planning on having this generate Java source code, it may not be readable but it should compile to bytecode
12:18:55FromDiscord<Rika> The fact that a good amount of libraries depend on C interoperability?
12:19:09FromDiscord<Rika> It’s prolly better to directly do bytecode no?
12:19:14FromDiscord<Forest> A big issue I'm thinking about is generating multiple java files to classes
12:19:57FromDiscord<Forest> In reply to @Rika "It’s prolly better to": Most likely yeah, but if someone wants to make it output a certain line of java code, that should be doable imo for easier intergration, especially if writing something like a Minecraft plugin
12:20:36FromDiscord<Forest> In reply to @Rika "The fact that a": Eh, main goal is getting the syntax working, it's kinda like how the JS backend is for the web specifically
12:20:48FromDiscord<Forest> JVM backend is just so we can use Nim on the JVM
12:22:10FromDiscord<Forest> Also, if I'm able to make one backend, what's stopping me from making more 👀
12:22:49FromDiscord<Rika> Well nothing
12:23:02FromDiscord<Rika> If you’re willing to put in the effort then there’s nothing really stopping you
12:23:19FromDiscord<Forest> Though my 'backends' would be more like building onto the compiler instead of my own fork
12:24:07FromDiscord<Forest> Since iirc it's possible to import passes.nim, right? No idea what it is for yet tho so gotta do some reading, especially if wanting to make my own backend
12:25:47*xet7 joined #nim
12:26:19FromDiscord<Forest> My main reason for doing this is because i hate Java syntax and other languages don't fill the gap imo
12:26:23FromDiscord<arnetheduck> https://github.com/oracle/graal/blob/master/docs/reference-manual/llvm/README.md - you can run `nlvm`-generated code straight on a JVM
12:26:32FromDiscord<Forest> Oh?
12:26:45FromDiscord<arnetheduck> "in theory" at least 😉
12:26:59FromDiscord<Forest> Aah, yeah but my issue is that i want to be able to interop with Java almost seamlessly
12:27:31FromDiscord<Forest> So importing classes, hell even making Java packages in Nim, would be interesting
12:27:43FromDiscord<arnetheduck> well, there are two parts to that,: the language instructions and the runtime - the latter is probably the bigger problem in terms of work
12:28:21FromDiscord<arnetheduck> it's similar to wasm for example: it's easy to generate wasm bytecode - much more work to also support wasi
12:28:38FromDiscord<Forest> Fair
12:28:44FromDiscord<luteva> is there an "index-engine" lib in nim? I mean something that builds up an index for incremental search/filter/tagging on the input given?

12:56:16FromDiscord<aph> does `std/re` have group matches? i couldn't find it, or should i use another lib?
12:57:38FromDiscord<enthus1ast> std/re needs pcre library, we also have a pure nim regex lib btw\: https://github.com/nitely/nim-regex
12:58:53FromDiscord<aph> oic, thanks
13:00:58FromDiscord<d4rckh> how could i debug a unserialization?
13:01:07FromDiscord<d4rckh> i keep getting `SIGSEGV: Illegal storage access. (Attempt to read from nil?)` when deserializing a sequence
13:01:17FromDiscord<d4rckh> if it has 1 element it works just fine. add another one and it crashes
13:01:52FromDiscord<enthus1ast> maybe one of the elements has an uninitialized ref
13:02:01FromDiscord<enthus1ast> ref/ptr
13:02:17FromDiscord<d4rckh> i cant have refs set to null?
13:02:39FromDiscord<d4rckh> its actually a ref obejct
13:02:41FromDiscord<d4rckh> (edit) "obejct" => "object"
13:02:51FromDiscord<d4rckh> i set it to null before serializing and i restore it at unserialization
13:04:02FromDiscord<enthus1ast> i don't know, depends on the serializer i guess
13:04:33FromDiscord<enthus1ast> checking for nil is a thing
13:05:37FromDiscord<d4rckh> i think i will do like
13:05:45FromDiscord<d4rckh> a raw version of the same type
13:06:01FromDiscord<d4rckh> without any refs

13:41:28FromDiscord<d4rckh> i have -d:debug

15:06:03FromDiscord<enthus1ast> void pointer ?
15:06:23FromDiscord<Shinyzenith> In reply to @Rika "i think they want": No no I wrote it in nim, I'm just more comfortable with explaining the idea in C
15:06:30FromDiscord<Rika> idgi then
15:06:43FromDiscord<Shinyzenith> In reply to @enthus1ast "void pointer ?": won't that break the type system?

15:07:34FromDiscord<Shinyzenith> I'll try that and get back to you
15:07:43FromDiscord<Rika> must be in the same file + same block
15:07:49FromDiscord<enthus1ast> yes
15:08:26FromDiscord<Shinyzenith> oh same block
15:08:27FromDiscord<Shinyzenith> I didn't do that
15:08:54FromDiscord<PyryTheBurger> how do i convert a string to int
15:09:13FromDiscord<enthus1ast> import strutils↵echo parseInt("123")
15:09:28FromDiscord<Shinyzenith> In reply to @Shinyzenith "I didn't do that": Yep it no longer complains about the types, thanks \@enthus1ast and @Rika

15:10:05FromDiscord<Rika> because it doesnt
15:10:11FromDiscord<Rika> just a limitation of the compiler rn
15:10:18FromDiscord<Rika> i dont know why
15:10:21FromDiscord<Shinyzenith> Huh That's interesting
15:10:34FromDiscord<enthus1ast> maybe this gets addressed when we have incremental compilation
15:10:38FromDiscord<Shinyzenith> what if I were to split it into two files because the current one will grow a lot↵↵what would I do in that case?
15:10:39FromDiscord<enthus1ast> but idk
15:10:47FromDiscord<enthus1ast> yes thats the thing
15:11:03FromDiscord<Shinyzenith> That's messy 😔
15:11:27FromDiscord<enthus1ast> you can do i kinda like c headers work and put the typedefs in one file
15:11:43FromDiscord<Shinyzenith> yeah I was thinking of making a types file or so
15:11:47FromDiscord<Shinyzenith> kinda like c headers

15:23:11FromDiscord<enthus1ast> finished($i) is a function call
15:23:30FromDiscord<enthus1ast> i guess finished($i) does not return another proc right?
15:23:30FromDiscord<PyryTheBurger> but how do i pass an argument to it
15:23:42FromDiscord<Rika> you do it in the function you pass the function into

15:24:31FromDiscord<Rika> can you give your code

18:35:20FromDiscord<enthus1ast> yes, use parseEnum from strutils↵(@d4rckh)
18:36:00FromDiscord<voidwalker> @enthus1ast ok, so that is an object.. you mean I can add it to the sequence if i put movie( ) before its members?
18:36:21FromDiscord<enthus1ast> when your object is called Movie then yes
18:36:53FromDiscord<voidwalker> object type is called movie, yes. and movies is seq[movie]
18:37:16FromDiscord<voidwalker> and i do not have a variable declared to store a single movie instance
18:37:43FromDiscord<enthus1ast> you don't need to, you can create one and directly add it to the seq
18:38:14FromDiscord<voidwalker> movies.add(movie(id:33,ptitle:"a",otitle:"b",year:1,runtime:1,rating:1))
18:38:15FromDiscord<voidwalker> this works
18:38:42FromDiscord<enthus1ast> i would recommend that you name your object types with a captical first letter
18:38:43FromDiscord<enthus1ast> like Movie
18:41:07FromDiscord<enthus1ast> this is more or less a convention, also also has the benefit that you still can use movie as a variable
18:42:02FromDiscord<voidwalker> yep, i stopped learning nim for almost a month, and now I forgot most of what I learned :\
18:42:36FromDiscord<enthus1ast> keep on going, its worth learning \:)
18:42:36FromDiscord<voidwalker> sent a code paste, see https://play.nim-lang.org/#ix=41iU
18:42:56FromDiscord<voidwalker> how do i force it to return uint32 ?
18:43:00FromDiscord<voidwalker> I also knew this but forgot :\
18:43:30FromDiscord<enthus1ast> sent a code paste, see https://play.nim-lang.org/#ix=41iW
19:05:09FromDiscord<voidwalker> yep, that works. Thanks. Now I got a case where there's no valid int to be parsed, but a "\N". Is there no way to get a 0 returned on parseUInt error instead of an exception ?
19:06:12FromDiscord<voidwalker> also, is this doc out of date, cause I only see parseint taking a var where to store the result of conversion, and the return value is number of processed chars
19:06:15FromDiscord<voidwalker> https://nim-lang.org/docs/parseutils.html#parseInt%2Cstring%2Cint%2Cint
19:26:50FromDiscord<PyryTheBurger> if i have some object, which has a int variable that grows all the time, when it gets to a certain number how do i completely remove that object from memory?
19:50:06FromDiscord<soundmodel> Any input as to how much benefit does Nim with C interop offer compared to just C
19:50:36FromDiscord<soundmodel> I'm interested in doing some Requested Libraries, but I'm confused as to whether the effort towards the bindings is worth it compared to just writing C

19:56:09FromDiscord<voidwalker> didn't notice it's a different unit
19:56:20FromDiscord<huantian> also, unless you really need that extra bit or you need uint for compatibility, I'd use a range instead
19:56:26FromDiscord<voidwalker> any idea how to build code for release instead of debug, in vscodium ?
19:56:38FromDiscord<huantian> are you using a buidl task?
19:56:44FromDiscord<voidwalker> i am using f6
19:57:03FromDiscord<Forest> How would i make a backend without modifying the Nim source?
19:57:32FromDiscord<huantian> if you wanna build for release, you either wanna make a build task that uses `-d:release`, or just run the command yourself: `nim c -d:release file.nim`, or if you're using nimble `nimble build -d:release`
19:57:39*wallabra joined #nim
19:57:57FromDiscord<Forest> Is it possible to make it so when the outputted binary is ran, it'll call the options like how it's done in the built-in backends?
19:58:54FromDiscord<voidwalker> where do i make that build task to use -d:release?

20:00:13FromDiscord<voidwalker> what's wrong with using uint though ?
20:00:24FromDiscord<voidwalker> no, I do not really need that extra bit
20:00:53FromDiscord<voidwalker> but there's a lot of data and i wanted to use the smallest types to accomodate it
20:01:51FromDiscord<huantian> In reply to @voidwalker "where do i make": check out <https://code.visualstudio.com/docs/editor/tasks>↵you wanna make a file at `.vscode/tasks.json` that runs a command, with `"group": "build"`↵then Ctrl + Shift + B to run it
20:03:36FromDiscord<huantian> sent a code paste, see https://play.nim-lang.org/#ix=41jj

20:04:53FromDiscord<voidwalker> @huantian found 'Nim: Build Command' in nim extension settings in vscodium
20:04:58FromDiscord<voidwalker> that will work

20:18:18FromDiscord<voidwalker> oh, you mean they get back to 0 after reaching their maxint.. that's expected, no ?
20:19:00FromDiscord<Andreas> yes, uint8 goes from 9 to 255 and then wraps to 0 and goes on
20:19:07FromDiscord<Andreas> (edit) "9" => "0"
20:20:48FromDiscord<voidwalker> I don't see a problem with that, if you know your data cannot cause it to go over
20:20:54FromDiscord<Andreas> (edit) "on" => "on.↵seems, many don't expect this and AFAIK this is the reason for int-type is the index-type to use in Nim. Which is a 'defensive' decision, but as obviously many ppl got this wrong, it is like so.."

20:36:49FromDiscord<voidwalker> the RAM usage makes sense, since it's a 1.5GB tsv I'm loading into memory, but the slightly faster execution ?

20:42:29FromDiscord<Forest> Don't really understand how I'd do this part, or if I'd need to write that part myself completely
20:52:41FromDiscord<soundmodel> In reply to @Professor Actual Factual "Depends on the library": Thank you. But shouldn't this also motivate some guidelines for understand "good C practices for Nim interop"? So that one could gauge beforehand, how feasible a binding will be?
20:59:45FromDiscord<soundmodel> In reply to @soundmodel "Thank you. But shouldn't": I'm thinking of doing this in Nim: https://github.com/mbrucher/PyVST/tree/master/pyvst
21:00:04FromDiscord<soundmodel> So now I'd wonder e.g. that if it maps to Python, then will it also map to Nim?
21:03:33FromDiscord<Professor Actual Factual> In reply to @soundmodel "Thank you. But shouldn't": Please note im not a C expert.↵↵Its true that documentation is somewhat lacking here. The only real C guidelines I can give you are. 1 Dont use macros/preprocessor, 2 keep external dependencies to a minimum, 3 ideally the C final API should a single header/C file, 4 try to stick to default builders like Make.
21:04:39FromDiscord<Professor Actual Factual> (edit) "Make." => "Make (this is nimterop specific or for generating a dynlib)."
21:04:49FromDiscord<soundmodel> a lot of well-used libraries aren't single-header libs
21:05:18FromDiscord<soundmodel> but this shouldn't cause a problem, if they're able to create JNI bindings and whatever, right?
21:07:25FromDiscord<Professor Actual Factual> sent a long message, see http://ix.io/41jx
21:08:04FromDiscord<Professor Actual Factual> Single header files are useful IMO because they are easier to bind to using the available interop tools. They are in no way a requirement.
21:08:31FromDiscord<Professor Actual Factual> (edit) "http://ix.io/41jx" => "http://ix.io/41jy"
21:09:29FromDiscord<soundmodel> I wonder if one can use 2. if the lib itself builds a lib
21:09:36FromDiscord<soundmodel> like VST does
21:11:28FromDiscord<Professor Actual Factual> sent a long message, see http://ix.io/41jz
21:12:35FromDiscord<Professor Actual Factual> C2nim does just that translates C files or h files to nim.↵Nimterop does all that, has more features, and allows you to script to install the dynlib. Think of it like the setup.py equivalent for nim.
21:13:17FromDiscord<soundmodel> it builds a .dll from the C code
21:13:26FromDiscord<soundmodel> so I wonder what it means for a binding language
21:15:13FromDiscord<voidwalker> If I do ` for movie in movies:`, where movie is an object, and movies is a seq[movie], how do I get the id of the current item iterated ?
21:15:39FromDiscord<voidwalker> or do I have to count it manually
21:18:07FromDiscord<soundmodel> In reply to @Professor Actual Factual "If thats the case": No I meant that the code builds a .dll from the code (creates a VST plug-in)
21:18:35FromDiscord<soundmodel> (edit) "plug-in)" => "plug-in), so essentially what has been written in the Nim bindings must go into that .dll"
21:18:48FromDiscord<soundmodel> (edit) "in" => "using"
21:19:14FromDiscord<huantian> In reply to @voidwalker "or do I have": check out https://nim-lang.org/docs/enumerate.html
21:19:40FromDiscord<Elegantbeef> You can also just do `for i, movie in movies`
21:20:06FromDiscord<soundmodel> In reply to @soundmodel "No I meant that": and I'm confused now between whether the bindings will first translate to C and then build normally or whether one needs to use the Nim compiler to "produce a .dll"
21:20:56FromDiscord<Elegantbeef> Nim always compiles to another language
21:21:10FromDiscord<soundmodel> I don't even understand how PyVST builds the .dll
21:21:15FromDiscord<Elegantbeef> I guess unless you talk about the nimvm where it's interpreted
21:21:27FromDiscord<Professor Actual Factual> In reply to @soundmodel "and I'm confused now": Im getting a bit confused here. Just to check we're on the same page. I'm assuming you are talking about going from C to Nim (and not the other away around)
21:21:43FromDiscord<soundmodel> In reply to @Professor Actual Factual "Im getting a bit": yes

21:45:54FromDiscord<Professor Actual Factual> In reply to @voidwalker "I wish he'd made": Im canada based and got free shipping. Whats up with that
21:46:08FromDiscord<voidwalker> in Europe it's 62 EUR + shipping
21:47:47FromDiscord<Professor Actual Factual> In reply to @voidwalker "in Europe it's 62": 80 CAD + free shipping
21:48:23FromDiscord<Elegantbeef> Where did it ship from domestic or US?
21:51:36FromDiscord<Professor Actual Factual> In reply to @Elegantbeef "Where did it ship": Bolton Ontario Canada. Low volume book sales are usually made on demand, therefore can be made locally. Hence the high price
21:58:54FromDiscord<soundmodel> In reply to @Professor Actual Factual "Ok I can give": Ehh, but how does it produce the api.dll?
21:59:15FromDiscord<Elegantbeef> It doesnt you compile libraries seperate to code that relies on them
21:59:45FromDiscord<soundmodel> but VSTs are shipped only by giving the user a .dll
21:59:56FromDiscord<soundmodel> so I don't understand how it can work if one's now required to give api.nim as well
21:59:58FromDiscord<Elegantbeef> Oh you're talking about generating a dll for a program
22:00:02FromDiscord<soundmodel> yes
22:00:08FromDiscord<soundmodel> DAW programs load a .dll
22:00:11FromDiscord<Elegantbeef> You export the required code then build with `--app:lib`
22:00:51FromDiscord<Elegantbeef> programs that load dlls look for specific procedure names that take specific arguments
22:01:16FromDiscord<Elegantbeef> You export your Nim procedures that match what it's looking for and it will just work
22:06:41FromDiscord<whisper> In reply to @enthus1ast "<@740841107117834330>\: a LPDWORD is": let buffer = newMString(256)↵ let pBuffer = cast[LPSTR](&buffer)↵ GetUserNameA(pBuffer, cast[LPDWORD](buffer))↵ result = cast[string](buffer)
22:07:20FromDiscord<soundmodel> In reply to @Elegantbeef "You export the required": What does "You export the required code" mean?
22:07:46FromDiscord<Elegantbeef> You give Nim `exportC` pragmas and a desired unmangled name for the procedure
