00:04:20FromDiscord<Rika> huh... nim is generating weird js? https://media.discordapp.net/attachments/371759389889003532/813561843913326642/unknown.png
00:04:45FromDiscord<Rika> length is readonly
00:05:00Prestigewhat data type?
00:05:29FromDiscord<Rika> im checking
00:05:41FromDiscord<Rika> supposedly string
00:05:58Prestigehm I mean it won't throw an error in js but it won't do anything
00:07:14FromDiscord<Rika> `Uncaught (in promise) TypeError: setting getter-only property "length"`
00:07:17FromDiscord<Rika> mhm
00:07:36Prestigehttps://i.imgur.com/VnGu3vs.png works in node at least
00:08:10Prestige"works"
00:08:14FromDiscord<Rika> i have use strict (and cannot change it)
00:08:26FromDiscord<Rika> https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Errors/Getter_only says only on use strict
00:08:40FromDiscord<Rika> cant do anything about removing use strict or so though
00:09:15PrestigeYeah, it's incorrect either way. Seems to just be incorrect js output I guess
00:09:50FromDiscord<Rika> imma look at the issues and see if its there
00:10:12FromDiscord<Rika> oh wow none

01:02:47FromDiscord<ElegantBeef> Any suggestions on how i can get around this shitty array impl? 😄 https://github.com/beef331/constructor/blob/master/src/constructor/variants.nim#L132
01:04:33FromDiscord<Rika> git gud
01:05:06FromDiscord<Rika> more seriously, i got no damn clue whatcha doing at a glance
01:06:16FromDiscord<ElegantBeef> If you scroll down to the very bottom you can see the usage of it, basically just makes an array of lambda's so you can call the proc on the variant object and it'll call the correct one
01:07:21FromDiscord<ElegantBeef> Instead of case statements, it just uses a LUT, which is kinda silly
01:07:57FromDiscord<ElegantBeef> I suppose i might be able to use a table to store all the impls for each kind then just call a `impl(object, proc)`

05:07:51FromDiscord<Hi02Hi> also i dont see you modifying the start and the endstring vars, so i would change them to immutable vars with `let` instead of `var`

05:15:23FromDiscord<Seedofarson> Okay
05:15:28FromDiscord<sh_oe> might be a dumb question, does nim allow you to store the address or a reference to a procedure in anyway?
05:15:40FromDiscord<Yardanico> @sh_oe wdym "store the address"?
05:15:45FromDiscord<sh_oe> like c
05:15:50FromDiscord<Yardanico> @Seedofarson You might want to give https://narimiran.github.io/nim-basics/ a read
05:15:52FromDiscord<Hi02Hi> pointer?
05:16:02FromDiscord<sh_oe> yeah a pointer to a procedure
05:16:16FromDiscord<Yardanico> `var a = myproc # a reference to myproc`
05:16:21FromDiscord<ElegantBeef> Yea it's a first class feature
05:16:23FromDiscord<sh_oe> oh really
05:16:30FromDiscord<sh_oe> well it was a dumb question then lol
05:16:32FromDiscord<sh_oe> thank you
05:16:39FromDiscord<Yardanico> you can pass procs just like normal variables, yes
05:17:13FromDiscord<sh_oe> ok just comming from c and its late (excuses excuses) thanks guys ya'll are great and i think i will read that basics page again

05:47:00FromDiscord<Yardanico> well of course, that's why it's the `enum` keyword :) although enums with holes have some limitations
05:48:47FromDiscord<arun> Good to know! It was non trivial to do so in golang, which doesn't have the `enum` keyword 🙂↵↵What type of limitations?

07:05:22FromDiscord<carpal> In reply to @arun "Blogged about recent improvements": mhhh
07:05:55FromDiscord<carpal> I'm reading <https://github.com/adsharma/py2many/blob/main/pynim/transpiler.py> but honestly I don't think it could be riable
07:08:09FromDiscord<carpal> it uses replace and string formatting to convert python code to nim
07:16:48krux02carpal: I think so, too. But it could be a first step to port some code.
07:17:27FromDiscord<carpal> the python code shouldn't be parsed by the repo owner, python is open source, anyone ↵can get the ast of any python code without write a parser, so you can follow the python updates without working everytime, maybe on features you are not able to implement
07:18:05krux02if python could be transpiled reliably in a language that is significantly faster than python, then there would probably a python compiler that does it in the packground and calling it a python performance improvement thing
07:18:12FromDiscord<carpal> search for a python parser online and redirect the ast to nim code generation
07:18:46krux02yea that is probably a better aproach.
07:19:01FromDiscord<carpal> In reply to @krux02 "if python could be": python is compiled to c officially
07:19:40FromDiscord<Yardanico> you mean cython? that's a different thing
07:20:04krux02I've heared about the go compiler that was first written in c++ and then later ported to go. What they did was, they limited their usages of c++ to a degree that was convertable to go and then, when everything was translatable they did the transition.
07:20:23krux02similarly with the nim compiler that was initially written in I think pascal
07:21:05krux02@carpal: I know there is a python to c compiler, but the generated C code is neither fast nor readable.
07:21:34krux02it is nothing you would want to use as a base for a C port of a python library.
07:21:53FromDiscord<carpal> In reply to @Yardanico "you mean cython? that's": no
07:22:05FromDiscord<carpal> python has a python to c compiler
07:22:06krux02probably mypyc
07:23:10FromDiscord<carpal> but if python exists is for the interpreter benefits
07:23:30FromDiscord<carpal> > if python could be transpiled reliably in a language that is significantly faster than python
07:23:40FromDiscord<carpal> referred to this ^
07:26:10FromDiscord<carpal> In reply to @krux02 "it is nothing you": python has good abstractions, the python tranpilation does not generate fast code because type matching and other operations are calculated at runtime by the PyObject, written in c
07:27:52*Kiloneie joined #nim
07:32:34FromDiscord<carpal> anyway. Transpilations usually don't generate a readable code, so I don't see the benefits in converting it to nim code
07:33:09FromDiscord<carpal> performance? convert it to c or c++ with some optimization tool
07:33:42FromDiscord<carpal> porting to nim and stop? again, it usually don't generate readable code
07:36:42FromDiscord<carpal> btw, is there any c backend library for nim?
07:36:47FromDiscord<Yardanico> as in?

07:39:38FromDiscord<Yardanico> matching what?
07:39:44GreaseMonkeyPython comes with an "ast" module in the stdlib which is really useful for if you want an already-existing syntax to compile into something
07:40:13GreaseMonkeyand i have a project lying around somewhere which hijacks the import machinery so you can have a module which gets exposed as Python but also transpiles to GLSL
07:41:14FromDiscord<carpal> clicking on the v percent
07:43:07madnightpython has some language features that makes it hard to compile
07:44:14madnightthe python to C code compiler basically has to spit out another python interpreter in C to run those features, that's why it is slow and unreadable, albeit being C
07:46:18madnighthowever it's very possible to have a high level language similar to python that compiles well, but you have to design it as such from the get-go
07:47:58FromDiscord<mratsim> compilation is easier with static typing.
07:49:23FromDiscord<mratsim> In reply to @carpal "anyway. Transpilations usually don't": We bootstrap Nimbus-eth1 which is part of the biggest commercial Nim project by transpiling a Python implementation.

08:03:50FromDiscord<mratsim> "everything is an object" in python, and all objects are dictionaries of properties.
08:03:54FromDiscord<carpal> in c compilation you can say "it is mandatory to use static typing"

08:06:52FromDiscord<mratsim> In reply to @whisperdev "Did anyone try this": every week someone asks about that.
08:07:41FromDiscord<Yardanico> @whisperdev isn't it really niche and C-specific, like the fact that it uses -nostdlib and its own libc?
08:07:57FromDiscord<carpal> but java vm is written in c lol and what more compatible than c? https://media.discordapp.net/attachments/371759389889003532/813683552238960651/unknown.png
08:08:18FromDiscord<Yardanico> @carpal he's talking about building applications, not the VM/compiler itself
08:09:18krux02@carpal: please don't pretend you know more than you do.
08:09:42FromDiscord<carpal> what
08:09:43FromDiscord<carpal> ...?
08:09:48FromDiscord<carpal> I only asked lol
08:09:51FromDiscord<carpal> this is so toxic
08:10:18FromDiscord<mratsim> agree I don't see any pretending
08:10:54FromDiscord<mratsim> Java VM is written in C in general but you don't have to.
08:11:16FromDiscord<mratsim> Java programs are just bytecode that any JVM can execute and you can write it in Nim if you want or assembly or JS.
08:11:44FromDiscord<mratsim> the run anywhere means as long a syou have a JVM runtime on your machine you can run the java program without recompiling it.
08:11:49FromDiscord<whisperdev> In reply to @mratsim "every week someone asks": Hehe you need a FAQ then
08:12:12FromDiscord<mratsim> I don't specially mind, it's an interesting project.
08:12:39krux02@carpal: The java runtime is written mostly in c++, but it is a just in time compiler that generates binary instructions at runtime.
08:13:08krux02The original interpreter was written in C I think. But that was only a java bytecode interpreter. Not much faster than python.
08:13:24krux02well a bit faster it was.
08:13:39krux02And these low level optimizations in the jvm are very platform specific.
08:14:20FromDiscord<carpal> jvm has an interpreter and a jit, I read that the interpreter is used more than the jit

08:14:54krux02@carpal: well it depends on how you weight thigs.
08:15:01*haxscramper joined #nim
08:15:16FromDiscord<mratsim> it depends on it depends
08:15:21FromDiscord<carpal> jit performs processor specific optimization I know
08:15:23krux02I you just measure in written lines of code, maybe. If you measure in execution time, probably not that much.
08:15:24FromDiscord<SneakyBaguette> I used to port JVM written in C for IoT (microcontroller and stuff) and it's full interpreter no jit. But server stuff makes heavy uses of jit
08:15:28FromDiscord<carpal> .net does the same
08:15:41krux02yes .net is basically a java clone
08:15:48krux02at least initially
08:15:55FromDiscord<carpal> mhh
08:15:56FromDiscord<SneakyBaguette> .net is microsoft Java with C++ syntax lol
08:16:04FromDiscord<mratsim> Then it got this Haskelly influence
08:16:06FromDiscord<carpal> a better clone imho
08:16:09FromDiscord<carpal> (edit) "imho" => "imho"
08:16:09krux02java already has c++ syntax
08:16:17FromDiscord<SneakyBaguette> F# looks solid
08:16:24FromDiscord<SneakyBaguette> (edit) "F# looks solid ... " added "though"
08:16:28FromDiscord<mratsim> Q# looks uncertain
08:16:31FromDiscord<carpal> In reply to @SneakyBaguette ".net is microsoft Java": java already has c++ syntax
08:16:38FromDiscord<carpal> (edit) "c++" => "c-like"
08:17:03FromDiscord<carpal> anyway, java and c# are on different layers
08:17:04krux02I've looked into C# and it seems to me that it really isn't a focused language at all. It is like c++ a mashup of everything.
08:17:18FromDiscord<SneakyBaguette> I find C # syntax closer to C++ than Java but that's not really.important anyway
08:17:36krux02tools work better than in c++ though.
08:17:36FromDiscord<carpal> I use c# and java sounds me so bad
08:18:10FromDiscord<carpal> In reply to @SneakyBaguette "I find C #": .net features are very nice
08:18:21FromDiscord<carpal> .net is also faster then java jit
08:18:22krux02Well with c# I am objectively in the past.
08:18:27FromDiscord<whisperdev> .NET and Java are super enterprisey
08:18:50FromDiscord<carpal> In reply to @SneakyBaguette ".net is microsoft Java": at your eyes yes...
08:19:31FromDiscord<carpal> you should try somethig to say if it is good or bad, and that opition will be for ever valid only for you
08:19:45FromDiscord<SneakyBaguette> Of course I don't disagree with that
08:20:03FromDiscord<SneakyBaguette> But I mostly works with low level stuff so VM are not something I use often
08:20:11FromDiscord<whisperdev> What I like about C# is that they brought it to almost every platform.
08:20:16krux02@carpal: Did you know that microsoft did develop their own JVM and then tried to play their embrace extend extinguish strategy on it. They got sued, had to stop it. And then made C# out of it?
08:20:42FromDiscord<carpal> how many years ago?
08:20:44FromDiscord<carpal> ahha
08:20:45FromDiscord<carpal> a lot
08:20:48krux02@wisperdev: yea, but it took them a very very long time.
08:20:58FromDiscord<SneakyBaguette> Calling C# Java Microsoft isn't a criticism of C#
08:21:10FromDiscord<whisperdev> @krux02: yeah that's surprising for a behemoth like Microsoft.
08:21:31krux02no not surprising at all.
08:21:44krux02They explicity wanted to prevent linux from becoming more popular.
08:21:47FromDiscord<whisperdev> On a different topic.How do I debug a Nim program "in production" that was compiled with d:release d:danger?
08:22:03krux02So it is not surprising that they didn't support it as a backend for their language.
08:22:16FromDiscord<carpal> anyway stop this discussion please, it is only toxic
08:22:34FromDiscord<whisperdev> It was a different era to be honest.
08:22:52krux02@whisperdev: you need debug symbols in order to debug
08:23:15krux02--debugger:native
08:23:23FromDiscord<SneakyBaguette> In reply to @whisperdev "On a different topic.How": Do you have the source available to modify & recompile or just the binary ?
08:23:29krux02it enables optimizations but also debug information
08:24:12krux02and then you need to run it with nim-gdb
08:24:13FromDiscord<SneakyBaguette> Aren't stacktrace turned off with -d : danger as well ?
08:24:41krux02ah and also rememebr, choosenim comes with a broken nim-gdb
08:25:03krux02if you have nim build from git, then nim-gdb works
08:25:36krux02@SneakyBaguette: nims own stack traces are turned off
08:25:59krux02@SneakyBaguette: but when you have debug symbols you get a stack trace from gdb
08:26:06FromDiscord<SneakyBaguette> Ah makes sense
08:26:09FromDiscord<Avatarfighter> o7 krux02, nice to see you back in here 🙂
08:26:17*Tanger quit (Quit: Leaving)
08:26:25krux02both gdb and nim keep their own stack information, that is pretty much redundant.
08:26:26FromDiscord<SneakyBaguette> I usually use debug() and stacktrace before using gdb
08:26:50krux02@Avatarfighter, I am mostly just lurking.
08:27:35krux02@SeakyBaguette: what `debug` are you talking about?
08:27:40FromDiscord<19> <krux02> are you still using nim? i really like your work with nim and opengl
08:28:15krux02well using nim isn't the right word, but nim is still a lot in my head and I think about it a lot.
08:28:17FromDiscord<SneakyBaguette> In reply to @krux02 "@SeakyBaguette: what `debug` are": It's basically echo but called debug
08:28:43krux02ok, it is probably a recent addition
08:29:29krux02@19: did you try opengl-sandbox?
08:29:53krux02I've invested a lot of work in that project, but somehow I feel like I am in isolation with that project.
08:30:09krux02Nobody says it is good/bad there are issues bugs.
08:30:13FromDiscord<19> i tried to run it on a mac and on a windows machine, no luck, i just like to look at the source code from time to time
08:30:30krux02yea sorry mac isn't supported.
08:30:35FromDiscord<19> i also watch your videos
08:30:51krux02windows should be working. if it doesn't please open an issue about it, so that I can fix it.
08:30:58krux02I will answer as fast as possible.
08:31:10FromDiscord<19> im gonna try now ^_^
08:31:15krux02my try to maintain a 0 open issue count for my projects.
08:31:43FromDiscord<19> that's awesome
08:32:20FromDiscord<19> how was your experience with spring C++ if you dont mind me askgin
08:32:46krux02I tried to improve the compatibility and reliability of the project, and that meant that I had to drop nimble as the build tool.
08:33:05krux0219: horrible
08:33:25FromDiscord<19> i can imagine
08:33:25krux02the build system was just torture I have no idea how they are able to develop with that engine.
08:33:44krux02I mean with that build system.
08:33:46FromDiscord<19> what c++ build system is not torture?
08:33:59FromDiscord<19> 😅
08:34:02krux02They need to seriously improve it, so that people can easily clone the project and start contributing.
08:34:12krux02And that also means seriously cutting the dependencies.
08:34:34krux0219: yea I am not used to the c++ build system nightmare anymore.
08:34:45krux02I think the best experience so far is Go.
08:34:51krux02you just write your sourcecdo.
08:35:06krux02Done, nothing else. It just compiles and works.
08:35:18krux02import from github, np
08:35:26krux02no package provider needed
08:35:42krux02no publish to some stupid list of released packages needed.
08:43:18FromDiscord<mratsim> In reply to @whisperdev "On a different topic.How": if you can't recompile it, you need GDB and a detective.
08:46:37FromDiscord<19> <Krux02> it works on win, ill open an issue regarding the font path ^_^
08:46:53krux02cool
08:47:07krux02never tested it personally
08:47:22krux02just linux testing here :P
08:49:06FromDiscord<19> lol, time to learn some DSL craziness
08:58:39FromDiscord<carpal> but does nim compiler generate a string and than compiles it with gcc or what?
08:59:06FromDiscord<carpal> I think it generates c code with an api
08:59:21FromDiscord<carpal> which?
08:59:56FromDiscord<Yardanico> it doesn't use an "api" and you can easily check that by looking into the c backend code
09:00:13FromDiscord<Yardanico> it just creates C source files with strings and then compiles them with the C compiler
09:00:19FromDiscord<Yardanico> there's nlvm which uses LLVM instead though
09:00:23FromDiscord<carpal> oh lol

09:01:57FromDiscord<Yardanico> @carpal those files in compiler/ are the C/C++/ObjC backend https://media.discordapp.net/attachments/371759389889003532/813697139767115806/unknown.png
09:02:13FromDiscord<Yardanico> main file of the c backend is https://github.com/nim-lang/Nim/blob/devel/compiler/cgen.nim
09:07:07FromDiscord<carpal> thank you
09:07:10FromDiscord<carpal> I'm reading it
09:11:16FromDiscord<carpal> but this makes slow the compilation
09:11:53FromDiscord<Yardanico> not necessarily
09:32:03krux02@carpal: nim compiles faster than c/c++ even though nim compiles to c/c++
09:32:14krux02the reason for that is header files.
09:32:19*Arrrrrrrr joined #nim
09:32:48krux02The inclusion of header files has quadratic complexity because every file potentionally includes every other header file.
09:33:02FromDiscord<Solitude> In reply to @carpal "but this makes slow": still faster than rust
09:33:41krux02In nim only generates the parts of the interface that are actually used. So no header files explosion
09:34:17krux02nim compilation is actually quite fast compared to other languages.
09:34:26krux02but compilation can be made arbitrarily slow
09:34:30krux02through macros.
09:34:37krux02they can kill every performace.
09:34:47krux02But people are not yet that crazy with macros.
09:35:40PMunchSpeak for yourself :
09:35:41krux02@19: regarding the nim dsl that I wrote, you can enable debugging and then the macros prints its generated source code.
09:35:42PMunch:P*
09:38:13FromDiscord<mratsim> Generics/concepts are slow than macros :/
09:38:17FromDiscord<mratsim> slower
09:38:52FromDiscord<mratsim> I don't know what's going on in sigmatch/semtypes/semchecks but it can be very slow.
09:38:57FromDiscord<19> <krux02> thanks, that will come in very handy since i have zero experience with dsls anyway xD
09:48:38FromDiscord<19> In reply to @krux02 "they can kill every": do you mean kill compile time speed or runtime execution speed?
09:49:09krux02both :P but mostly compile time performance
09:49:35krux02and generally people tend to completely ignore compile time performance and call it "zero cost abstraction"
09:49:37FromDiscord<19> can we cache the macros results?
09:50:05FromDiscord<19> the term zero cost abstraction is very elusive
09:50:15krux02there are efforts to do incremental compilation to do exactly that
09:50:25FromDiscord<19> cant wait for incremental comp
09:51:34krux02my thoughts on incremental compilation would be very posix oriented :P
09:52:01saemHmm, is nim compiler speed tracked over time anywhere?
09:52:50krux02make a fork of the process after every module. fork on Linux is cheap. Then when recompilation is necessary, resume to the latest fork that still recompiles all the current changes.
09:53:00krux02saem, nope
09:53:13krux02it is on my todo list though
09:53:41krux02the old todo list from when I was still working on the compiler.
09:53:54krux02I would implement trackang of all tests as well.
09:54:06krux02so that you can plot which tests are most expensive etc.
09:54:18krux02and how much a single test performance changed over time.

09:59:28saemAm curious if @mratsim notices any difference in the latest devel version in code bases like arraymancer etc?
09:59:37SebastianMGuys is there a way to initialize sequence with range of numbers like in python l = list(range(1,10))?
10:00:47FromDiscord<mratsim> In reply to @saem "Am curious if <@570268431522201601>": in terms of compilation time? It's been a while since I tested in Arraymancer. I definitely feel Nim slowness in Constantine but unsure if it became slow or if I'm just using too much generics/static
10:00:57FromDiscord<mratsim> and compile-time evaluation
10:01:08FromDiscord<mratsim> (doing some bigint precomputation at compile-time).
10:02:56FromDiscord<Yardanico> @SebastianM not that I know of, you can just use a for loop though
10:03:06FromDiscord<Yardanico> and preallocate the seq with the length since it's known
10:03:26FromDiscord<InventorMatt> toseq(1..10) should work for that
10:03:58FromDiscord<Yardanico> ah yeah

10:27:47Clonkk[m] * What's the trick to have a generic proc construct a generic object ? I get a "expression has no type or is ambiguous" error ? https://play.nim-lang.org/#ix=2QtT
10:29:45FromDiscord<Yardanico> typedesc can't exist at runtime
10:29:51FromDiscord<Yardanico> it's a compile-time only type
10:30:03FromDiscord<Yardanico> why do you want to store `t` in the object?
10:30:36FromDiscord<Yardanico> e.g. this works just fine https://play.nim-lang.org/#ix=2QtU (but I don't think that this usage of addr is safe)
10:30:46FromDiscord<hamidb80> In reply to @hamidb80 "regex has sideEffect!? 😕": any idea?
10:30:56FromDiscord<Yardanico> sorry, no idea about that
10:31:16Clonkk[m]<FromDiscord "<Yardanico> e.g. this works just"> Oh ok ! Yeah ignore the usage of addr, in practice it's a C function that gives an allocated pointer
10:33:49Clonkk[m]<FromDiscord "<Yardanico> why do you want to s"> The idea is just to encode the type since I store a ``pointer``
10:35:09FromDiscord<Solitude> In reply to @hamidb80 "regex has sideEffect!? 😕": lines is proc that reads file from filename line by line
10:35:12FromDiscord<Solitude> not line splitting
10:35:33FromDiscord<hamidb80> In reply to @Solitude "not line splitting": oh,
10:35:47FromDiscord<Yardanico> @hamidb80 for line splitting there's `strutils.splitLines` iterator/proc
10:36:30FromDiscord<Yardanico> @Clonkk well you generally don't need to store the type as long as you don't need to do different stuff based on the object type at runtime
10:37:44Clonkk[m]<FromDiscord "<Yardanico> @Clonkk well you gen"> I do. I have a ``ptr value`` type that represents an array type and the type of the array is encoded at run-time with a ``apply_array_type`` proc
10:40:36FromDiscord<Yardanico> huh
10:40:52FromDiscord<Yardanico> then you need to think of your own way to store the type - e.g. if it's a predefined known set, you can use an enum
10:44:22Clonkk[m]<FromDiscord "<Yardanico> then you need to thi"> I'd rather not have this limitations of having to extend the enum for every defined type. Passing it a generic parameters will be enough for a first draft (even if it disallows doing ``x.myproc[type]()``)

10:58:11FromDiscord<Yardanico> @XeroOl you can install mingw through your distro's package manager

11:08:30FromDiscord<Yardanico> you can just use @ to universally ping people on both discord/irc
11:09:11PMunchHmm, I should do some more video content. But that requires freeing up time in my schedule..
11:09:19FromDiscord<19> i tried that but couldnt find some members in the discord autocompletion
11:09:38FromDiscord<Yardanico> well, because they are not there
11:09:42PMunchI don't think IRC users autocomplete on Discord

11:13:33PMunchOoh, I should check that chapter out for reference
11:13:37FromDiscord<mratsim> I have written macros when the compiler held a gun to my head.

12:08:56FromDiscord<Yardanico> https://github.com/nim-lang/Nim/issues/14873
12:08:59FromDiscord<Yardanico> maybe this?
12:12:13nxnl[m]I looked at that earlier, but I don't really know what it means
12:13:02FromDiscord<Yardanico> do you have an object that has a member of the type `Lock`?
12:13:03nxnl[m]I don't have to touch the lock in any way, just define it as a property on this one class and it fails to compile

12:45:30FromDiscord<flywind> I miss it
12:45:40FromDiscord<Yardanico> I mean you can make a simple template just for stuff that has `close`
12:45:50FromDiscord<Yardanico> ah actually no
12:45:58FromDiscord<Yardanico> it needs to be a macro, but anyway, it can be relatively simple

13:06:50FromDiscord<KnorrFG> is the only difference between var and let the mutability? I ask because you can use new and addr with a var - variable but not with a let variable. Var feels more like a save pointer.
13:07:42FromDiscord<KnorrFG> but it seems returning a var from a proc still makes a copy, so im a little confused in that regard
13:09:38FromDiscord<haxscramper> `ref` is a "safe pointer". When you return `var` from a procedure and assign it to something then it might make a copy

13:10:22FromDiscord<haxscramper> But if you return `var T` and then run `procThatMutatesArgs(arg: var T)` then it shouldn't make a copy and instead will reuse the same object IIRC

13:15:17FromDiscord<KnorrFG> i tried the second one, because it works with an object that is defined in foreign code, but then it seems to return a copy
13:15:33FromDiscord<Yardanico> e.g. https://nim-lang.org/docs/with.html
13:15:42FromDiscord<Yardanico> @KnorrFG as I said, replace _both_ instances

13:19:23FromDiscord<KnorrFG> actually i just want to understand what happens under the hood, and my mental model was from c++ where u return a ref to self. then I noticed that it might be easier and used the python example. So i thought in the end it would be the same
13:19:43FromDiscord<Yardanico> it doesn't have any global state that I know of so it should work just fine, maybe your problem is with something else
13:21:45FromDiscord<Yardanico> @KnorrFG you can use `ref object` for the behaviour you want

13:23:54FromDiscord<rramos.eth> `result` is filled by calling a C function that returns a cstring
13:24:45FromDiscord<rramos.eth> which i convert to string with $
13:27:47FromDiscord<rramos.eth> it makes me wonder if the issue is related to the cstring being garbage collected, and not the parseJSON proc being the problem

13:35:29FromGitter<gogolxdong> commented out isLiteral of nim-chronos to get it compiled with arc , seems there is memory leak.
13:35:57FromDiscord<Yardanico> you should try orc instead
13:36:00FromDiscord<flywind> async + arc = leaking
13:37:06FromGitter<gogolxdong> orc crashes the application
13:38:45krux02@19: that is cool, whenever I think technical artist this is what I think about: https://youtu.be/Y7f0YtzWBG4?t=206
13:39:09FromDiscord<19> wow this game
13:39:09krux02the idea behind my code is to make opengl easier to understand.
13:39:09FromDiscord<Yardanico> @gogolxdong then you should stick to `refc` for the time being and try to minimize (I know it can be hard) the bug with orc
13:39:20FromDiscord<19> oh nice
13:39:25FromDiscord<Yardanico> since with `arc` you'll leak memory because of using async (even with nim-chronos)
13:39:30FromDiscord<KnorrFG> In reply to @haxscramper "it works because function": cool, ty
13:39:56krux02yea I really like oddworld. But I can't do art like that.
13:40:05krux02I just like the genre
13:40:35krux02Starting with Prince of Persia (1989), Flashback, Oddworld ...
13:40:41krux02all great games
13:40:59FromDiscord<19> i think oddworld used 3d models rendered to sprites
13:41:05krux02yes
13:41:13krux02the old version yes,
13:41:14FromDiscord<19> diablo1/2 also
13:41:17krux02The remaster is full 3D
13:41:35FromDiscord<19> i like that style
13:41:36krux02diablo 2 remaster also uses 3D modles
13:42:10FromGitter<gogolxdong> refc leaks as well, make application more unstable than orc
13:42:10FromDiscord<19> yeah, the old one still looks better though
13:42:26FromDiscord<19> kind of like starcraft broodwar vs starcraft 2
13:42:43krux02well, I think that is also a lot of nostalgia.
13:42:58FromGitter<gogolxdong> will it be fixed once chronos supports arc.
13:43:03krux02But I also think that for certain styles 256 colors actually improve the atmosphere
13:43:25FromDiscord<19> yeah probably that nostalgia kicking in
13:43:28krux02KKND just looks better in my opinion than KKND 2
13:43:44FromDiscord<19> but i like how protoss looked better for example in broodwar
13:43:45krux02I don't think it is just nostalgia.
13:43:54krux02both kknd and kknd 2 are old games.
13:44:01krux02I played both as a child.
13:44:37krux02there are several reasons why some old style graphics look better than modern styles.
13:44:46krux02And I think a lot of it has to do with smoothness.
13:44:51FromGitter<gogolxdong> I am testing orc again.
13:45:05krux02Old style is rough with precise borders. Modern style is smooth.
13:45:22FromDiscord<mratsim> @gogolxdong there is a PR with experimental orc support in Chronos
13:45:23FromDiscord<Yardanico> @gogolxdong are you sure that it actually leaks?
13:45:29FromDiscord<Yardanico> i mean refc
13:45:45FromDiscord<mratsim> https://github.com/status-im/nim-chronos/pull/135
13:45:47krux02When your game is post apocalypse in a Mad Max like environment, smooth is not a property that is very important.
13:45:52FromDiscord<19> its also funny how when u emulate old games written in asm they perform exactly like the old, but in the new ones ( ps1 ps2 emulations) they are buggy with emulation xD
13:46:32krux02well ps1 isn't buggy anymore,
13:46:39krux02but sure I get what you want to say.
13:47:09krux02and no, they do not perform exactly like the old.
13:47:58krux02games that abused the hardware too much to get to the desired result tend to not work in emulation because the games don't use specified behavior anymore.
13:47:59FromDiscord<19> yeah understandable
13:48:27krux02I think commander Keen in dosbox is not like commander keen in native dos on old hardware.
13:48:41FromDiscord<19> i really like wc3 reign of chaos style
13:48:51FromGitter<gogolxdong> testing with refc as well , orc is noticable slow than arc/refc.
13:49:00krux02I don't, I always thought that WC3 looked ugly.
13:49:09krux02from the beggining.
13:49:23krux02I prefer WC2 over WC3
13:49:43FromDiscord<19> what about wc3 vs wc reforged
13:49:55krux02I don't really care personally.
13:49:56FromDiscord<haxscramper> we have `#gaming` and `#offtopic`
13:50:08krux02I am not attached to WC3, but I heared about the dispute about reforged.

14:24:05FromDiscord<KnorrFG> im currently trying to wrap a c-library (the drawing area part of libui to be precise) there is an object type path. to create one you need to call drawNewPath(fillMode) and then it needs to be freed after use with drawFreePath(). To wrap this safely I think normally I would have to use new and pass drawFreePath as a finalizer, but here I cannot really just use new because I need to call the c-function, right?

15:26:19FromDiscord<Rika> or why getInput is a closure
15:26:20FromDiscord<konsumlamm> a closure is a function that captures another variable (in this case `vt`)

15:28:34FromDiscord<Rika> thats why you cant use closures

15:28:55FromDiscord<KnorrFG> sent a code paste, see https://play.nim-lang.org/#ix=2QvY
15:30:55FromDiscord<konsumlamm> the reason is probably that threads must own the values they use (with the current default GC at least), so you can't reference variables that are possibly in another thread

17:12:32FromDiscord<hamidb80> any idea?
17:13:31leorize[m]@hamidb80 spawn analysis is flawed, that's all
17:15:00leorize[m]CPS should simplify this stuff in the future
17:22:00FromDiscord<mratsim> CPS will have the exact same problem as spawn :p
17:22:19FromDiscord<mratsim> and then you add openarray on top

17:23:44leorize[m]wouldn't Isolated[T] helps?
17:23:53FromDiscord<mratsim> ah right.
17:23:57FromDiscord<mratsim> I have to check that
17:24:31FromDiscord<Avatarfighter> @hamidb80 this paper describes an implementation of cps with C <https://www.irif.fr/~jch/research/cpc-2012.pdf> I found it pretty useful in understanding why cps is cool
17:25:18*PMunch quit (Quit: leaving)
17:27:54FromDiscord<mratsim> this is the one that sparked everything
17:30:04FromDiscord<exelotl> I tried implementing something similar a couple of years ago... but it turned into a buggy mess↵So I ended up using ucontext + nimcoro instead for my use case
17:30:16FromDiscord<exelotl> it works brilliantly
17:34:51leorize[m]the current Nim implementation is at https://github.com/disruptek/cps
17:35:16leorize[m]however disruptek and Zevv has both stopped development afaik
17:38:00FromDiscord<KnorrFG> sent a code paste, see https://play.nim-lang.org/#ix=2Qxm
17:40:40FromDiscord<haxscramper> You can't have non-defaulted arguments following defaulted ones
17:41:06FromDiscord<haxscramper> Code block you passed after `:` is set to `fillMode`, withich is not `untyped`
17:41:27FromDiscord<haxscramper> So it undergoes semcheck, but because code in the block relise on injected variable you get error
17:41:32FromDiscord<haxscramper> (edit) "relise" => "relies"
17:41:32FromDiscord<KnorrFG> oh ... ooops. that was actually a pretty stupid question, im sorry
17:42:14FromDiscord<haxscramper> But if you want to have default template arguments and pass code blocks you can try creating overloads that pass arguments, though I'm not sure if it works well in the end
17:42:39FromDiscord<KnorrFG> great idea, ill try
17:43:07FromDiscord<haxscramper> But right now you need to pass all arguments explicitly, or write a macro that accepts something like `letPath (line, fillMode = value)`
17:43:15FromDiscord<haxscramper> Note the space before `(line`
17:43:34FromDiscord<haxscramper> But this is really a hack

20:43:20*Gustavo6046_ is now known as Gustavo6046
20:44:16FromDiscord<exelotl> Two things that bug me:↵1. "of of"↵2. Table matches aren't optimised to just a single lookup (a la withValue)
20:45:05FromDiscord<haxscramper> Optimizing to single lookup might create copies
20:45:18FromDiscord<haxscramper> If you mean nested tables
20:46:31FromDiscord<exelotl> I mean how↵`if k in tbl: echo tbl[k]`↵does 2 lookups
20:47:06FromDiscord<haxscramper> Yes, but I need to check if the key is in the table anyway instead of raising
20:47:31FromDiscord<haxscramper> Not really sure how it can be done in one lookup
20:47:46FromDiscord<haxscramper> But maybe I'm missing something
20:47:52FromDiscord<exelotl> withValue from the tables library is optimised to just do a single lookup
20:48:36FromDiscord<exelotl> So it could be possible to use that I guess
20:49:14FromDiscord<haxscramper> sent a code paste, see https://play.nim-lang.org/#ix=2Qzk
20:49:42FromDiscord<haxscramper> `contains` also does `rawGet`, and compares it
20:49:58FromDiscord<haxscramper> So `withValue` does two lookups too, it just might look like only one
20:50:15FromDiscord<haxscramper> oh well, wait
20:50:20FromDiscord<haxscramper> ye, it does not lookup
20:51:09FromDiscord<haxscramper> But that is an optimization that relies on implementation-specific detail
20:51:57FromDiscord<exelotl> Yeah, withValue is the only part of the tables lib that does that
20:52:39FromDiscord<exelotl> (edit) "does" => "can be used to do"
20:52:45FromDiscord<haxscramper> The biggest performance hit is actually from implicit copying that might occur during matching, ideally it all should be done via immutable views
20:53:30FromDiscord<haxscramper> And I want to rewrite pattern matching to use them when this feature becomes more stable
20:55:00FromDiscord<exelotl> Ah yeah that'll be good

21:10:54FromDiscord<Unaimend> In reply to @leorize "https://play.nim-lang.org/#ix=2Qzw": Thank you very much, If I would change the return type of build to DeBruijnGraph without ref, would a call of the procedure produce a copy while returning?

21:23:17FromDiscord<XeroOl> I'm looking into how to build or otherwise obtain it
21:25:24leorize[m]depends on what os are you compiling to
21:26:51FromDiscord<XeroOl> I'm on linux, trying to get something cross compiled so it can run on windows 10
21:27:11leorize[m]you can cross compile/obtain pcre via the conan package manager
21:28:19leorize[m]or you can downloads nim's dlls.zip and copy pcre64.dll from there
21:28:31leorize[m]it's somewhere in Windows' download page iirc

22:46:58FromDiscord<dom96> `choosenim <version>`
22:47:04FromDiscord<XxDiCaprioxX> thanks
22:47:18FromDiscord<ElegantBeef> Dont forget `choosenim update <version>` 😄
22:47:32FromDiscord<dom96> huh, wow, there is a big netsplit on IRC
22:48:06FromDiscord<XxDiCaprioxX> In reply to @ElegantBeef "Dont forget `choosenim update": the new update changed the ssl functionality and nobody can help me figure it out
22:48:20FromDiscord<ElegantBeef> Well maybe the author of choosenim can help 😛
22:48:36FromDiscord<XxDiCaprioxX> It is not the fault of choosenim xD
22:48:39FromDiscord<ElegantBeef> Ah

22:48:55FromDiscord<XxDiCaprioxX> The 1.4.4 was specifically to "properly" check for ssl certificates
22:48:58*dimi34ka joined #nim
22:49:19FromDiscord<XxDiCaprioxX> I'd love to choosenim the newest version but I prefer my programs working. thanks though 😛
22:49:31FromDiscord<dom96> hah, what problems are you running into with the new ssl stuff?
22:49:31*dimi34ka quit (Remote host closed the connection)
22:50:14FromDiscord<XxDiCaprioxX> well, I have a discord bot that now refuses to start with the error "no SSL/TLS CA certificates found"
22:50:56FromDiscord<dom96> nice
22:51:21FromDiscord<XxDiCaprioxX> Sooo, I'm staying 1.4.2 until I figure out what the hell
22:51:48FromDiscord<dom96> Yeah, SSL is a PITA :/
22:52:24FromDiscord<XxDiCaprioxX> yupp, so I prefer it not working to it actively trying to sabotage me
22:52:55FromDiscord<XxDiCaprioxX> I much rather focus on working on a FEN reader
22:53:11FromDiscord<XxDiCaprioxX> Anyways, as I ahem ahem "fixed" it, Ima go now, cya!

23:56:35FromDiscord<lithdew> Hello 👋 new here, checking out nim for the first time
23:57:20FromDiscord<Avatarfighter> @lithdew Welcome to the community 🙂 I hope you enjoy your stay ! Don't be afraid to ask questions no matter how dumb they sound, we've all been there
23:57:30FromDiscord<Avatarfighter> Does anyone know of a library where you can encrypt with public/private keys and initialize a public key with a supplied modulus and a derived number?
23:57:32FromDiscord<Avatarfighter> @Rika
23:57:59FromDiscord<lithdew> In reply to @Avatarfighter "Does anyone know of": Supplied modulus; under a curve or just RSA?
23:58:08FromDiscord<Avatarfighter> Just RSA
23:58:52FromDiscord<Avatarfighter> I think I need to wrap a library for this but I am unable to find something that lets me supply a modulus(n) and a derived number(e) I think I'm just bad at google
