00:03:41FromDiscord<Yardanico> Why
00:03:52FromDiscord<Yardanico> You can have userbots in telegram
00:06:34FromDiscord<kaletaa> i'm not sure if any of the libraries support interacting with those buttons
00:06:37FromDiscord<kaletaa> and quizzes
00:06:47FromDiscord<kaletaa> and the other misc stuff durov jammed into telegram
00:07:04FromDiscord<kaletaa> v https://media.discordapp.net/attachments/371759389889003532/724415118842134596/unknown.png

00:07:14FromDiscord<kaletaa> i'm not sure what you call those
00:08:17FromDiscord<Yardanico> @kaletaa yeah of course they do, not in Nim though (since I didn't make my telenim into something easily usable yet)
00:08:25FromDiscord<Yardanico> But you can check Python libs for example
00:08:34FromDiscord<Yardanico> Telethon, pyrogram, etc
00:08:43FromDiscord<kaletaa> yeah those have great support
00:09:07FromDiscord<Yardanico> Well they support the full user API too
00:09:13FromDiscord<kaletaa> yeah it doesn't seem like a hard task
00:09:17FromDiscord<kaletaa> it just seems tedious

00:18:00FromDiscord<j-james> Hmm so↵This is probably a dumb question↵But how can I call a different Nim program in the same directory
00:18:35FromDiscord<j-james> Is the only way to `import` it↵And call its functions
00:22:05FromDiscord<Yardanico> Not sure what you mean
00:22:24FromDiscord<Yardanico> You can compile the program into the binary and execute it as a binary instead if that's what you want
00:22:35FromDiscord<Yardanico> From another program
00:25:49FromDiscord<j-james> Yeah I phrased that badly
00:26:09FromDiscord<j-james> Can you import functions from other Nim files?
00:26:26FromDiscord<Yardanico> Yes?
00:26:38FromDiscord<Yardanico> you maybe mean you want to fully qualify the module name?
00:26:55FromDiscord<Yardanico> Like "module.work()" instead of "work()"?
00:27:26FromDiscord<j-james> Thanks↵I think I was just doing it wrong
00:27:35FromDiscord<j-james> (edit) 'I' => 'that was ' | removed 'that'
00:33:23FromDiscord<kaletaa> i didn't know about that `from module import nil` feature
00:33:31FromDiscord<kaletaa> it's epic
00:37:11FromDiscord<Yardanico> Well kinda
00:37:17FromDiscord<Yardanico> You know you can qualify even without that?
00:37:42FromDiscord<Yardanico> !eval import strutils; echo strutils.split("hello would")
00:37:45NimBot@["hello", "would"]
00:37:54FromDiscord<Yardanico> *world
00:38:09zedeusyeah it breaks operator overloading and UFCS while making your code longer, very epic
00:38:17FromDiscord<Yardanico> ^^
00:38:36FromDiscord<kaletaa> lmao
00:38:41FromDiscord<Yardanico> You can just import the normal way and fully qualify for stuff you want

00:46:27FromDiscord<Skaruts> is this how a sequence can be converted to a C array: `cast[ptr Vertex](vertices)`?
00:46:30FromDiscord<Skaruts> I'm trying to give it to this function: <https://github.com/oprypin/nim-csfml/blob/master/src/csfml/private/graphics_gen.nim#L5028>
00:46:31FromDiscord<Skaruts> which takes `ptr Vertex`
00:46:41FromDiscord<Skaruts> proc*
00:47:29FromDiscord<exelotl> @Skaruts cast[ptr UncheckedArray[Vertex]](vertices) ?
00:47:50FromDiscord<Skaruts> gonna try that
00:48:09FromDiscord<Yardanico> @Skaruts not like that
00:48:22FromDiscord<Yardanico> Nim sequence is by default len, cap, pointer to data
00:48:26FromDiscord<exelotl> Oh sorry, you just wanna do addr vertices[0]
00:48:33FromDiscord<Yardanico> Yeah, that'll work
00:48:38FromDiscord<Skaruts> oh
00:48:43FromDiscord<Skaruts> yea that makes sense
00:48:44FromDiscord<exelotl> But the thing I wrote is how they should've defined their function
00:49:01FromDiscord<exelotl> (probably)
00:49:14FromDiscord<exelotl> (Maybe)
00:49:24FromDiscord<Yardanico> csfml wasn't really updated for a few years but I think it still works
00:49:37FromDiscord<Skaruts> it does work, yea 🙂
00:52:06FromDiscord<Skaruts> shouldn't wrappers abstract types though? Like, for example that proc could be defined to take `openarray` and do the conversion itself
00:52:20FromDiscord<Skaruts> abstract type conversions*
00:52:49FromDiscord<exelotl> Oh yeah you're right that would be way better
00:53:21FromDiscord<Skaruts> I find myself writing many templates to abstract stuff like this, also for int->cint conversions...
00:53:36FromDiscord<Skaruts> not just with csfml
00:53:43FromDiscord<Yardanico> Well it depends on the library
00:53:53FromDiscord<Yardanico> E.g. gintro abstracts quite a lot of stuff
00:54:01FromDiscord<Yardanico> It's much nicer than using the raw GTK api
00:54:43FromDiscord<Skaruts> imo it makes usage smoother
00:55:13FromDiscord<Skaruts> well the thing I'm doing still doesn't work... but at least I got the array thing sorted
00:55:17FromDiscord<Skaruts> thanks guys

04:24:57FromDiscord<SeanOMik> Or am I not looking in the correct place
04:25:10Yardanicoyes forward declarations
04:25:19FromDiscord<SeanOMik> Ah thats the name
04:25:25FromDiscord<SeanOMik> Found it
04:25:29FromDiscord<SeanOMik> https://nim-lang.org/docs/tut1.html#procedures-forward-declarations
04:25:30FromDiscord<SeanOMik> Thanks
04:25:39Yardanicohopefully in the future we won't need them :)
04:25:46FromDiscord<SeanOMik> Wdym?
04:26:22Yardanicowell, right now one of the features on the "milestone" is to make code reordering work for all stuff
04:26:37Yardanicoso you wouldn't even need forward declarations for recursive dependencies (when a calls b, b calls a)
04:26:49Yardanicobut that's relatively far from now :P
04:26:54FromDiscord<SeanOMik> Yeah
04:27:01FromDiscord<SeanOMik> Sounds cool though
04:27:19FromDiscord<SeanOMik> I guess recursive includes are also probably far a way too then
04:27:22FromDiscord<SeanOMik> (edit) 'then' => 'then?'
04:27:38FromDiscord<Rika> i dont think we're adding cyclic imports if thats what you mean
04:27:46FromDiscord<SeanOMik> Yeah thats what I was meaning
04:27:49Yardanico@SeanOMik they already kinda work
04:27:50FromDiscord<SeanOMik> Why not?
04:27:53Yardanicoyou just have to structure your code properly
04:27:57FromDiscord<SeanOMik> Yeah
04:28:00Yardanicoyou can have recursive dependencies
04:28:18FromDiscord<SeanOMik> I guess cyclic imports could cause spaghetti code.
04:28:34FromDiscord<Rika> its more complicated for the compiler
04:28:40FromDiscord<Rika> might slow down compilation a lot
04:28:44FromDiscord<SeanOMik> Oh okay
04:28:57FromDiscord<SeanOMik> Well thanks for answering questions guys
04:29:17FromDiscord<Rika> ~~i'm here just to ask and answer questions~~
04:29:33Yardanicowell why would you be here otherwise :P
04:30:45FromDiscord<Rika> perhaps i wanted to advertise a program i made in nim
04:30:55FromDiscord<Rika> or i wanted to interact with the community
04:31:09FromDiscord<Rika> or i wanted to know about the newest news about nim
04:31:09Yardanicoyou're just answering questions before they're asked then :D
04:31:15Yardanico /s
04:31:26FromDiscord<Rika> that is true though
04:32:04Yardanicooh no
04:32:04Yardanicohttps://github.com/Zed-Inc/nim_braces
04:32:07Yardanicosomeone actually created it
04:33:00FromDiscord<Avatarfighter> I believe you mean oh yes
04:33:06YardanicoI mean oh no surely
04:34:41FromDiscord<Avatarfighter> almost as good as bython
04:34:42FromDiscord<Avatarfighter> https://github.com/mathialo/bython
04:34:56Yardanicogood thing that it's abandoned
04:35:02FromDiscord<Avatarfighter> hahah fr
04:35:37FromDiscord<Avatarfighter> while looking for bython I typed brython and I found an implementation of python but for webpages wtf
04:35:38FromDiscord<Avatarfighter> https://brython.info/
04:35:39Yardanicoi wonder why github projects have so much daily git clones

04:37:47Yardanicothe problem with these things is compatibility with python itself

04:37:56Yardaniconice joke :)
04:38:27FromDiscord<Avatarfighter> Haha
04:38:30FromDiscord<InventorMatt> you could probably embed nimscript into a webpage
04:38:38FromDiscord<Avatarfighter> oh i do not doubt that you couldn't
04:38:44Yardanicowe have nim js too
04:38:53Yardanicobut yeah, with emscripten you could probably embed the whole nim compiler on the web page
04:38:57Yardanicoand compile to JS on the fly
04:38:58FromDiscord<Avatarfighter> oh wow
04:39:00Yardanicoand run the JS
04:39:03FromDiscord<Avatarfighter> that's very cool

05:17:27FromDiscord<Zed> hey, im suprised it actually works
05:18:27FromDiscord<Zed> although now that i've gotten used to nims whitespace i cant get used to the braces XD
05:19:09FromDiscord<Rika> some people prefer one or the other, or dont even have a preference
05:19:16FromDiscord<Elegant Beef> Im in the latter!
05:19:27FromDiscord<Elegant Beef> Also rika you literally just said "People have feelings"
05:19:33FromDiscord<Zed> personally i prefer the '@' instead of braces

06:37:35FromDiscord<Skaruts> can anyone get me this little test to work: https://play.nim-lang.org/#ix=2pQ3
06:37:52FromDiscord<Skaruts> I keep getting errors no matter what I do, I dn't even know anymore...
06:38:21FromDiscord<Skaruts> the goal is just to assign a different `print_val` proc depending on which kind the object is
06:40:18FromDiscord<Skaruts> (I forgot to assign a value to val1 and val2, though)
06:40:53FromDiscord<Rika> https://play.nim-lang.org/#ix=2pQ4
06:41:41FromDiscord<Rika> `print_proc` changed to this `print_proc:proc(self: Foo): string` and i fixed the `result.kind` stuff (dont do that basically)
06:41:56FromDiscord<Rika> then you have to re-pass in `f1` and `f2` to `print_proc`
06:42:16FromDiscord<Rika> since `f1.print_proc` returns the proc, it does not call the proc with `f1`
06:42:18FromDiscord<Rika> @Skaruts
06:42:44FromDiscord<Skaruts> oh, I always thought `new result` was equivalent to `result = Foo(kind: Foo1)`
06:42:54FromDiscord<Skaruts> thanks!!
06:42:58FromDiscord<Skaruts> 🙂
06:43:06FromDiscord<Yardanico> It is
06:43:13FromDiscord<Yardanico> new result is redundant here
06:43:25FromDiscord<Rika> i didnt remove it lmao
06:43:27FromDiscord<Rika> sorry
06:43:30FromDiscord<Yardanico> It's okay
06:43:38FromDiscord<Rika> but you cant set `result.kind` since it discriminates
06:43:50FromDiscord<Rika> has to be part of the constructor `Foo(kind: value)`
06:43:57FromDiscord<Yardanico> You can :)
06:44:03FromDiscord<Rika> i mean, its not a great idea to
06:44:04FromDiscord<Skaruts> I always did it this way though
06:44:23FromDiscord<Yardanico> @Skaruts it's worse for the compiler and stuff
06:44:43FromDiscord<Yardanico> Object construction syntax is better since you don't need to care if it's a ref or not and stuff like that
06:44:46FromDiscord<Skaruts> so result = Foo(kind: Foo1) is preferable?
06:44:51FromDiscord<Yardanico> Yeah
06:45:04FromDiscord<Skaruts> nice to know
06:45:06FromDiscord<Yardanico> You can also split it over multiple lines
06:45:23PMunch@Yardanico, can you? I thought that was disallowed prior to 1.0
06:45:42FromDiscord<Yardanico> Can do what?
06:46:08FromDiscord<Rika> you can still do it afaik
06:46:29FromDiscord<Yardanico> Yeah, there even was a PR which fixed it for arc
06:46:33FromDiscord<Skaruts> yea, you can, I've been doing it all along and had no complaints from the compiler so far
06:46:35PMunchChange the discriminator in a variant object
06:46:41FromDiscord<Yardanico> Yeah you can
06:46:57*nikita_ is now known as nikita`
06:47:18FromDiscord<Yardanico> With checks you will get a proper error if you access an invalid branch, without checks on - well, good luck xD
06:47:37FromDiscord<Yardanico> Actually maybe I'm wrong
06:48:02FromDiscord<Yardanico> Don't remember if it's a part of checks or an exception/defect
06:48:42PMunchThis is what I was talking about: https://play.nim-lang.org/#ix=2pQ6
06:48:53PMunchError: unhandled exception: assignment to discriminant changes object branch; compile with -d:nimOldCaseObjects for a transition period [FieldError]
06:49:52FromDiscord<Yardanico> An right you can't change the kind only
06:50:01FromDiscord<Yardanico> You need to construct a new object
06:50:09FromDiscord<Yardanico> When you're changing the kind
06:50:14PMunchYeah
06:52:48FromDiscord<Yardanico> Ah actually wait
06:52:49FromDiscord<Skaruts> actually, now that I think about it, I'm not sure about my last statement (that you can still do that), as my current project doesn't use any of this, and I only updated to latest nim two days ago...
06:52:57FromDiscord<Yardanico> It might be not allowed by default
06:53:03FromDiscord<Yardanico> But it's allowed with arc
06:53:14FromDiscord<Yardanico> See https://github.com/nim-lang/RFCs/issues/209

06:55:08alehander92_oi
06:55:41FromDiscord<Skaruts> btw, I'd like to know if what I am doing is worth it: I'm doing that proc assignment thing to prevent having to use case/of when both kinds use the same proc to do different things (essentially mimicking dynamic dispatch, I guess, but still keeping it static)
07:02:04ZevvAraq: nothing is *wrong* with CPS per se, it's just that I can't seem to find the time nor the concentration to properly work at it.
07:03:16ZevvMy plan was to methodically work through all the required transform rules, I guess it's about ten or fifteen or so, and then implement them incrementally.
07:03:39alehander92_that's so many
07:11:00Zevvyah but its the typicall decreasing returns, or how do you call it
07:11:13Zevvtwo rules get you going with linear code with no control flow
07:11:21Zevvthen one more allows basic whiles
07:11:27Zevvone more for the break
07:11:38Zevvone for break with label
07:11:38Zevvetc
07:12:20Zevvand also, this needs to go into the compiler because macros just cant go all the way
07:24:28PMunchHow was everyones NimConf by the way?

07:44:13FromDiscord<ikrima> i'm trying to make a generic tree visitor but i can't get the function to be dispatched with the derived type
07:46:45bungarchived videos
07:49:09PMunch@Rika, why would you need locks for async`
07:49:20FromDiscord<djazz> I enjoyed NimConf a lot!
07:49:26FromDiscord<djazz> I watched it all live
07:49:33PMunchThose in the locks module will work, but they won't be optimal
07:49:33FromDiscord<Rika> I'm just asking right now
07:49:46FromDiscord<Rika> I don't need them right now
07:49:53PMunchdjazz, I really liked it as well. The parts I got to watch. So many good presentations
07:50:15PMunch(And interesting to see how many cool thing people have done in Nim that I've never heard about)
07:50:49PMunch@Rika, but what do you imagine using them for? Async doesn't run at the same time as such, so there is no reason to lock anything
07:51:12PMunchAnd if you don't use tryLock you will lock up your entire execution thread
07:51:13FromDiscord<Rika> but async can hit the same pieces of code at the same time
07:51:18PMunchNo it can't
07:51:29FromDiscord<Rika> i mean, consecutively
07:52:00PMunchOnly if you have yielded control
07:52:01FromDiscord<Rika> not *at the same time* per se, but one can enter an async section whilst there's something awaiting in that same section
07:52:44PMunchAnd since you don't need your "locks" to be thread-safe you can simply use a bool as a lock
07:53:43PMunch@ikrima, what do you mean the "most derived type"`
07:53:46PMunch?*
07:54:02PMunchCould you write up a small sample of what you're trying to do?
08:00:07alehander92_it seemed cool
08:00:08FromDiscord<ikrima> @PMunch yup! was just doing that

09:00:29FromDiscord<ikrima> @mratsim heh, this is exactly what i'm building except for my main app and what drove me to nim to try to generate
09:00:37FromDiscord<mratsim> and lifted into a compile-time/runtime compiler implemented as macro: https://github.com/numforge/laser/tree/master/laser/lux_compiler↵https://github.com/numforge/laser/tree/master/laser/lux_compiler/core↵↵In particular the types: https://github.com/numforge/laser/blob/master/laser/lux_compiler/core/lux_types.nim#L14-L132
09:01:10FromDiscord<ikrima> 👍 excellent; that'll be very helpful
09:01:45FromDiscord<mratsim> Note that I wanted something that worked at compile-time so I add extra restrictions:↵- no inheritance/methods so no visitors
09:02:20FromDiscord<ikrima> the inheritance was a compromise; i got frustrated trying to do simple things in Nim for a couple of days
09:02:42FromDiscord<mratsim> I've also gathered some references on DSL implementations techniques here: https://github.com/mratsim/compute-graph-optim/blob/master/arraymancer_discussion_347.md#semantic-pass-and-the-extension-problem
09:02:57FromDiscord<mratsim> though I didn't focus on visitors because they don't work at compile-time
09:03:01FromDiscord<ikrima> i wanted my parse tree to be irregular heterogenus (so named subfields) but I couldn't figure out how to do variant constraints in Nim?
09:03:56FromDiscord<ikrima> sent a code paste, see http://ix.io/2pQB
09:04:23FromDiscord<mratsim> it will be hidden behind variant
09:04:58FromDiscord<mratsim> there is something that you can do with NimNodes, proc foo(a:NimNode{nkIdent}) but it's no documented at all
09:05:08FromDiscord<mratsim> I don't know if it works for any variants either
09:05:30FromDiscord<ikrima> gotcha
09:05:39FromDiscord<mratsim> Also this might help you as well: https://github.com/mratsim/trace-of-radiance/blob/master/trace_of_radiance/support/emulate_classes_with_ADTs.nim
09:05:55FromDiscord<mratsim> it's for emulating classes with variants
09:06:04FromDiscord<ikrima> brilliant

11:08:43FromDiscord<Recruit_main707> thx
11:10:17FromDiscord<lqdev> what would be a good name for a proc that temporarily maps something to virtual memory? `map`? `access`? `mutate`?
11:10:54FromDiscord<lqdev> the proc accepts a callback with a pointer to the data and the size of the buffer
11:12:34FromGitter<antonkatz> looking into JS generation, it seems that a function even if marked with * is not exported. How would I go about using nim generated js inside a bigger js project?
11:13:25FromDiscord<Recruit_main707> antonkatz you probably also need to add `{.exportc.}` pragma

13:58:43FromGitter<erhlee-bird> awesome the first one works ⏎ I'll try the second one
14:00:31alehander92_i think the first one is the way zah wanted the concepts to be used
14:01:04alehander92_by using a similar syntax to the way the construct is used in real code, but this might be just my wrong impression

15:15:14FromGitter<ynfle> Why does `strtabs` not have `==` proc?
15:17:03FromDiscord<mratsim> One does not simply compare string tables
15:17:48Araqnever needed it
15:18:01FromGitter<ynfle> Because of style insensitivity?
15:18:13Araqequality on hash tables is hard, you never know if the order should matter
15:18:54FromGitter<ynfle> I'm assuming that's why we have `OrderedTable` and `Table`
15:19:02AraqI mean, you would use an OrderedTable if the order matters, yes
15:19:26Araqbut OrderedTable is often also used for convenience, see json.nim
15:19:31FromGitter<ynfle> Order doesn't matter but I wan't style insensitivity
15:19:44Araqso create a PR
15:20:08Araqbut usually dicts are compared to {:} and to nothing else
15:20:22Araqwhich can be done with x.len == 0
15:20:24FromGitter<ynfle> Would you accept one that compares based on order or not?
15:20:38FromGitter<ynfle> I know but I want specific mappings
15:20:42Araqwell it's an unordered table so the order shouldn't map

16:26:39FromGitter<kdheepak> @genotrance the julia community is excited to see you are using the binaries in nim :)
16:31:02shashlickyep - they were considering getting rid of static libraries - probably that's not how they use the libs
16:31:12shashlickbut it is valuable to us
16:31:24shashlickhopefully they expand their efforts
16:31:46shashlicki also looked into vcpkg but it doesn't work without VC++ on Windows
16:32:02*gangstacat joined #nim
16:32:25shashlickplus they don't really post prebuilt binaries so it is more about providing stable way to build locally
16:33:05shashlick@kdheepak where do you see this discussion
16:34:54FromGitter<kdheepak> On slack, the binary builder developers linked this issue of yours: https://github.com/JuliaBinaryWrappers/Zlib_jll.jl/issues/1#issuecomment-647008970
16:34:56disbot➥ zlib static binaries need to be recompiled with -fPIC to be compatible with PIE builds
16:35:23FromGitter<kdheepak> Why do you want static binaries?
16:36:21FromGitter<kdheepak> If you want to join the julia slack you can chat directly with them. They are a very knowledgeable group.
16:36:58FromGitter<kdheepak> And I'm happy to make introductions there / provide necessary context (based on my understanding).
16:37:46shashlickI'll join the slack - where is it
16:37:49FromGitter<kdheepak> In Julia everything is loaded only at runtime. This is equivalent to using `import dynlib; dynlib.loadLib` in nim.
16:38:14FromGitter<kdheepak> julialang.slack.com/
16:38:20shashlickI figured, but in Nim people can statically link too to simplify distribution
16:38:44*Jesin joined #nim
16:38:52FromGitter<kdheepak> But I think statically linking will have other issues, right?
16:39:03shashlickI understand if they don't want that burden but will be great if they do cause it will benefit many beyond Nim as well
16:39:06FromGitter<kdheepak> You can't statically link the C / C++ runtime anyway.
16:39:20FromGitter<kdheepak> Worth having a conversation about it :)
16:40:04shashlickTypically you build on an old glibc
16:40:21shashlickOr there's musl as well and they do provide musl builds
16:40:21FromGitter<kdheepak> Once you join you should join the `#binarybuilder` slack channel / topic.
16:40:30shashlickOk will do in a few minutes
16:40:59Araqstatic linking is completely misguided but very fashionable
16:41:16Zevvyeah and then you put it in a container
16:41:24Zevvbecause
16:41:50Araqthere seems to be this idea that you can pretend your Linux OS is a JVM, well it isn't and it won't be one
16:42:51Zevvone can always try
16:42:56shashlickI agree, dealing with c/c++ dependencies is a nightmare
16:43:35Araqand all your friends you want to share your x86_64 ELF Linux binary with don't own PCs anymore but Android based phones :P
16:44:07shashlickBut they are valuable nonetheless so it's worthwhile to accelerate the nim ecosystem

16:54:19FromDiscord<Recruit_main707> too much questions
16:54:28FromDiscord<Recruit_main707> many*
16:55:09FromDiscord<Recruit_main707> arc even wins c++, impressive
16:55:25Yardanicowell we have to consider that nim is using -O3 but he's using -O2 for C and C++ :)
16:56:38Araqunfortunately arc related bugfixes take away from arc related optimizations
16:56:38Araqyou should really use LTO too, we don't inline well
16:56:38FromDiscord<Rika> O3 was shown to not really give a difference over O2 from what i remember reading on some shady ass website maybe
16:56:45FromDiscord<Recruit_main707> 0.4 is a considerable bit though, is O2/O3 the diference?
16:56:56Yardanicolemme check
16:57:31YardanicoC with O2 took ~3 sec for me
16:57:34YardanicoC with O3 - same :D
16:58:14FromDiscord<Recruit_main707> lmao get owned
16:58:34FromDiscord<Rika> so the shady ass website i read was correct
16:59:11Araqyou can always use 'ptr' btw, last time I checked Nim v1.0 had that one too
16:59:13FromDiscord<mratsim> it is
16:59:30FromDiscord<mratsim> -03 matters mostly for loop-based call
17:00:03FromDiscord<mratsim> compilers can play with unroll, vectorization, deep hoisting and various things that led to increased codesize
17:01:05FromDiscord<mratsim> if you're doing an interpreter or cryptography it's no difference, if you do image processing or numerical computing you will have some
17:01:11FromDiscord<Recruit_main707> do we win rust using int32 though?
17:01:17Yardanicolemme try
17:01:29Yardanicowith the code in the repo I get mean 2.587s, with using uint32 instead of "int" - 2.296s
17:01:33Yardanicolets see the results for rust on my machine
17:01:35FromDiscord<mratsim> Rust uses uint64 by default though
17:01:43Yardanico@mratsim in the code the author explicitly used u32
17:01:48Yardanicoand for C they used "int"
17:01:52FromDiscord<mratsim> ah
17:02:26FromDiscord<mratsim> using uint32 will remove all the overflow checks from the release build
17:02:36YardanicoI'm testing with -d:danger anyway :)
17:02:49Yardanicoand rust version on my machine is mean 2.345s
17:02:52Yardanicoslower than nim with u32
17:03:00FromDiscord<Recruit_main707> ezz
17:03:34FromDiscord<Recruit_main707> also, python big oof, i bet my pc can even run it faster (i hope)
17:03:59*vikfret joined #nim
17:04:19FromDiscord<Rika> so whos making the pr 😉
17:04:20FromDiscord<mratsim> also using unsigned would allow the compiler to use better optimizations for mod
17:04:53FromDiscord<mratsim> for example a compiler cannot transform div 2 to a shift right unless it proves that the variable is never negative
17:04:55FromDiscord<Recruit_main707> i love it when you guys start talking about optimizing this benchmarks
17:04:57Yardanicooh no, someone made a PR with parallel D version XD
17:06:37Yardanicomaybe I should try with weave
17:06:55FromDiscord<mratsim> you can use OpenMP for this, but you need to make sure you use setupForeignTHreadGC or the strings will crash
17:09:14FromDiscord<KingDarBoja> > "so who's pinging technisha" ↵I could
17:09:34FromDiscord<Recruit_main707> would using an iterator improve performance?
17:09:36YardanicoWith weave I easily get under 500ms
17:09:38*Vladar quit (Quit: Leaving)
17:09:43FromDiscord<Recruit_main707> damm
17:09:45Yardanicowith string output
17:10:06FromDiscord<Rika> so weave's actually a library made by a magician
17:10:09Yardanicoyes
17:11:06Yardanicowell I get so fast because it actually seems to use all my 16 threads :) which is really gud
17:11:54Araqis it fair though to use multi-threading? C doesn't have a lib for it after all and we cannot use anything invented after 1970
17:12:07Yardanicohaha
17:13:09FromDiscord<Recruit_main707> how does weave work?
17:13:26FromGitter<ynfle> I'm trying to modify `unittest` to work at compile time and ran into an issue the compiler complains that `Error: cannot evaluate at compile time: formatters` in a `template` where it is introduced with a `bind` statement. Any way to get around this?
17:13:51FromDiscord<Rika> > how does weave work?↵@Recruit_main707 real life magic
17:14:19Araqjust don't. use 'when isMainModule: static: doAssert(...)'
17:14:49FromGitter<ynfle> Handling the error messages and having clean output is a pain
17:15:46YardanicoD parallelised version seems to be a little bit slower than weave, but it uses dlang's stdlib parallelism
17:16:18FromDiscord<Recruit_main707> just add weave to stdlib :smart:
17:16:41Araqha; I knew it. "mu mu, must not be a dependency"
17:17:02*Senny joined #nim
17:17:02*Vladar joined #nim
17:17:13FromDiscord<Rika> Yardanico: ez fix, make weave stdlib 😛
17:17:15Yardanicowell I won't PR it anyway since it's just a small benchmark, but yeah, weave is nice :) i have nothing against using "third-party" modules
17:17:28Araqwon't be accepted
17:17:43AraqYardanico: no, please do the PR
17:18:14FromDiscord<Rika> araq: i am joking T_T
17:18:37Araqah ok
17:18:55Araqit's always hard to tell when you live in surreal programmer land
17:19:15FromDiscord<Rika> text makes it even hard to tell
17:19:28FromDiscord<Recruit_main707> hard-er
17:20:06FromDiscord<Rika> i apologize it is 1 am
17:20:18FromDiscord<Rika> ive woken up around 14ish hours ago by now
17:22:43Yardanicowait I didn't know weave works with arc lol
17:22:55YardanicoI just compiled with --gc:arc and it worked XD although a little bit slower
17:27:31Yardanico@mratsim do you know test_gc_arc in weave passes on latest devel?
17:27:36Araqdoes it even use arc related stuff?
17:27:37Araqweave does its own memory management
17:27:53Araqso any difference you measure might be noise
17:27:57FromDiscord<mratsim> No I didn't know that it passed
17:28:22YardanicoI just tested, full output - https://gist.github.com/Yardanico/13a2813ab7df46c6c63b2cbeae56e529
17:28:34FromDiscord<mratsim> internally it doesn't use ARC, but it needs to at least pass the tests so that I can explore sending seq/strings in channels
17:30:11FromDiscord<mratsim> (.e. serializing seq/strings in tasks)
17:31:25Yardanicoalso Araq, with --sinkInference:off (without that it crashes in same fillBody thing) nim compiler can compile hello world with --gc:arc (something a bit more complex still fails)
17:31:40YardanicoI mean the compiler compiled with --gc:arc
17:33:13Araqcool, I'm working on #14402 fwiw
17:33:16disbothttps://github.com/nim-lang/Nim/issues/14402 -- 3AsyncHttpClient segfaults with gc:orc, possibly memory corruption ; snippet at 12https://play.nim-lang.org/#ix=2pSW
17:33:52Yardanicoand for us linux plebians ssl with arc is broken on devel :P
17:34:01Yardanicobut yeah, cool :)
17:34:20FromDiscord<mratsim> btw I manage to put mentions of DrNim everywhere in the Rust concurrency thread (though apparently I gathered a lot of downvotes). It's sad that a large portion of the Rust community is so focused on memory safety and ignores the other issues introduced by threads
17:34:35Yardanicoah wait I'm wrong it works (?)
17:35:22Yardanicoah nvm, it still fails with that C compiler error, I thought it was the same as in #14240 but that's not the case
17:35:23disbothttps://github.com/nim-lang/Nim/issues/14240 -- 5[exceptions:goto] C compiler error with dynlib pragma calling a proc ; snippet at 12https://play.nim-lang.org/#ix=2nzx
17:35:38Araqmratsim: well DrNim is still vaporware
17:35:54Araqhelp is appreciated
17:36:23FromDiscord<mratsim> Like VTable, it's documented Vaporware so we can get people excited about it 😉
17:36:58Araqwe have enough to get people excited about
17:37:19Araqwe need more production-ready stuff
17:37:35Araqit's always the famous last 80% of work
17:37:42FromDiscord<mratsim> 😛
17:38:05FromDiscord<mratsim> so regarding production ready stuff, afaik you didn't say if you saw this compiler fuzzer porject: https://github.com/agroce/afl-compiler-fuzzer
17:39:07FromDiscord<mratsim> one issue that will likely come up with our audits is that Nim itself is unaudited, but also not fuzzed
17:40:08FromDiscord<mratsim> this was even used to crash formal verification tools 😄
17:41:36Yardanicowell we already have quite a lot of low-priority compiler crash issues :)
17:42:33FromDiscord<mratsim> fuzzing might reveal a refactor needed to handle several early instead of monkey patching for a couple of bugs
17:44:20*marnix joined #nim
17:45:32FromGitter<ynfle> What does `<//>` do?
17:46:06Yardanicoit's old deprecated syntax for owned ref (needed for bootstrapping I think), you shouldn't use it :)
17:48:31FromGitter<ynfle> `owned` instead or just leave it out
17:51:25Yardanico?
17:51:54FromDiscord<mratsim> @Araq, is there an outline of stuf that needs implementation for Z3 integration?
17:52:15FromDiscord<mratsim> like is everything in teh DrNim page implemented?
17:52:18AraqI run DrNim on the Nim compiler and fix bugs when I work on it
17:52:56ee7[m]@ynfle see https://forum.nim-lang.org/t/6440
17:53:07Araqmost of it is implemented but 'forall' and 'exists' are not mapped to anything useful
17:53:57Araqmratsim: if fuzzing helps your audit we'll do it. if not, I won't anytime soon, terrible cost-benefit tradeoff
17:54:17Araqas we also have real users finding real bugs that affect them
17:55:26FromDiscord<Isomorpheus> what is up with the syntax highlighting in vscode? why are keywords like "let" and "import" the same color as identifiers?
17:55:33Yardaniconot for me?
17:55:36Yardanicotry to change the theme
17:56:07FromDiscord<Isomorpheus> yeah it was my Shades of Purple theme. hmmmmm
17:56:33FromDiscord<Isomorpheus> i wonder why? it's not a problem for my other code
17:56:45FromDiscord<KingDarBoja> share your settings
17:57:06Yardanico@Isomorpheus well I don't know either, I've used Monokai Vibrant theme for a very long time now and I like it a lot :)
17:58:20FromDiscord<mratsim> The compiler is out of scope of this initial audit
17:58:34Yardanicothat's how monokai vibrant looks like (with fira code ofc) https://i.imgur.com/bq7qBig.png
17:58:53Yardanicoalso it's sad that only nim.nvim has semantic syntax highlighting (a nimsuggest feature)
17:59:49FromDiscord<Isomorpheus> whats that whitespace color extension
18:01:21FromDiscord<KingDarBoja> VSCode Default theme https://media.discordapp.net/attachments/371759389889003532/724685474278408252/unknown.png

18:02:37FromDiscord<Isomorpheus> @KingDarBoja https://marketplace.visualstudio.com/items?itemName=ahmadawais.shades-of-purple
18:02:40FromDiscord<Isomorpheus> try this one
18:03:22Yardanicohttps://i.imgur.com/4mophuO.png that's the guides extension
18:03:33Yardanico@Isomorpheus lemme try
18:03:40FromDiscord<KingDarBoja> @Isomorpheus ugh, too many purple to my eyes!
18:03:55Yardanicofor me too
18:03:56FromDiscord<Isomorpheus> see if the syntax highlighting works properly
18:03:58Yardanicohttps://i.imgur.com/ertcwiM.png
18:04:08Yardanicoyeah the theme is kinda broken I guess :P
18:04:20FromDiscord<Isomorpheus> not for my other languages: rust, typescript, python
18:04:30Yardanicowell, most themes I tried work just fine for nim
18:04:33FromDiscord<KingDarBoja> I do use this extra setting to change the color of types
18:04:39FromDiscord<KingDarBoja> sent a code paste, see http://ix.io/2pT7
18:05:26FromDiscord<Isomorpheus> unrelated but im trying to do string interpolation in nim but it's inserting the quotation marks...? can I just get a string within a string
18:05:44Yardanicohow are you doing it?
18:06:09Yardanico!eval import strformat; let a = "hello"; echo fmt"{a} world!"
18:06:13NimBothello world!
18:06:39FromDiscord<KingDarBoja> https://github.com/arcticicestudio/nord-visual-studio-code
18:06:46FromDiscord<KingDarBoja> I love this theme btw
18:07:18Araqtry the "nim-alt" plugin
18:07:25Araqits highlighting is better
18:07:25Yardanico@KingDarBoja https://marketplace.visualstudio.com/items?itemName=s3gf4ult.monokai-vibrant is what I use
18:07:51FromDiscord<Isomorpheus> can I get a type at runtime
18:07:59FromDiscord<KingDarBoja> Oh the constract is high, which makes it easier to read
18:08:07FromDiscord<KingDarBoja> Nice choice Yard
18:08:08Yardanico@Isomorph "kinda"
18:08:18Yardanicotypes don't exist at runtime but you can use typeof(something) to get its type
18:08:37Yardanicowhy do you want types at runtime?
18:08:50Yardanicobtw, there's also another vscode extension
18:09:02Yardanicohttps://github.com/bung87/vscode-nim-lsp uses nimlsp instead of directly using nimsuggest
18:09:09FromDiscord<KingDarBoja> I really love how it looks with Nord

18:09:25FromDiscord<KingDarBoja> I am keeping it lol
18:10:14shashlicki prefer plain monokai, it's not too blue
18:10:41FromDiscord<Isomorpheus> onvm I had to use `getStr` on the json node first
18:11:01FromDiscord<KingDarBoja> Araq: this one? https://github.com/GaryM-exkage/vscode-nim-alt
18:11:03shashlicki wish there was a dull black theme, easier on the eyes
18:11:21Yardanico@King yeah
18:11:42Yardanicoalso KrispPugg released dimscord v1.0.0 today, I should update ircord :)
18:11:56Yardanicowell, in devel
18:12:02YardanicoI mean in dimscord devel*
18:12:03FromDiscord<KingDarBoja> I have already installed it

18:12:13FromDiscord<KingDarBoja> That's the one with the customisation option
18:12:45Yardanico@Isomorpheus well, not really
18:12:50Yardanicothere's "with" but it's different
18:12:56Yardanicoand you can make your own withAs easily :P
18:12:58FromDiscord<KingDarBoja> Did my discord started updating out of nowhere?
18:13:37FromDiscord<Isomorpheus> well where is the with equivalent for this postgres connection code
18:15:09FromDiscord<Rika> make a macro yourself is what yardanico said i think
18:15:26FromDiscord<Isomorpheus> lol
18:15:49Yardanicosomething as simple as https://play.nim-lang.org/#ix=2pT8 can easily work
18:16:28Yardanicoah right forgot to add block
18:16:48Yardanicohttps://play.nim-lang.org/#ix=2pT9 so it opens a new scope
18:18:01FromDiscord<Isomorpheus> this is neat but feels like it should be built into something

18:38:20FromDiscord<Rika> i think you need a string
18:39:01FromDiscord<KingDarBoja> If I recall, jsonb is a json-like structure, so probably you need to use a jsonnode, but haven't used the nim API

19:21:15YardanicoXXDDDDD
19:21:22FromDiscord<Vindaar> does github work for you guys?
19:21:23narimiranoh, i guessed correctly
19:21:27FromDiscord<Vindaar> completely dead for me
19:21:30narimiranwho would have thought
19:21:30Yardanico@Vindaar yes, works just fine
19:21:35FromDiscord<Vindaar> weird
19:23:10Yardanicolo and behold - weird options bug https://github.com/nim-lang/Nim/issues/14758
19:23:12disbot➥ C compiler error with options and a proc field in an object ; snippet at 12https://play.nim-lang.org/#ix=2pTz
19:23:14Yardanicowill see if it's a regression
19:23:35Yardanicowell it works just fine on 1.2.0 so surely it is :D
19:26:00Yardanicowill run bisect on it
19:29:40Araqgah github down!
19:29:49Yardanicoweird, not for me
19:30:36Araqso how can reproduce the arc ssl bug?
19:30:51Araqremember I cannot be bothered to start my linux vm
19:30:57Yardanicoheh
19:31:01FromDiscord<Clyybber> Araq: Unfortunately not at all, even on linux
19:31:10FromDiscord<Clyybber> oh nevermind
19:31:24FromDiscord<Clyybber> I thought you were talking about the httpclient bug
19:31:38Araqthe httpclient bug is easy to reproduce on OSX
19:31:50Araqvia -d:nimDebugArc I always get a nil future
19:32:06Araqit's just that I don't understand the aliasing
19:32:08Yardanicothe options bug is https://play.nim-lang.org/#ix=2pTC btw (if github is down :P)
19:32:27Yardanicothe first bad commit is the PR which added inline to options, but of course it's not the root cause
19:32:54nisstyreI've been test driving an x window manager I wrote in Nim all day today and it is mostly good enough to actually use now
19:38:48Yardanicook now let's try to see if the inline bug itself is a regression or not
19:45:49FromDiscord<mratsim> great Github is down
19:45:55Yardanicohow?!
19:45:56Yardanicoit's up for me lol

19:47:04FromDiscord<mratsim> I can't resolve their DNS
19:47:30Yardanicoso apparently this inline options bug is caused by specializing genericReset ??
19:48:22FromGitter<akavel> Hi! I'm trying `import pegs` then `const pegHex = charSet({'0'..'9', 'a'..'f', 'A'..'F'})`, and I'm getting: `Error: {} must have the set type` - any idea what's going on? the same seems to work if I replace `const` with `let` o_O
19:51:03FromDiscord<mratsim> hack: try using a "let foo {.compileTime.}" and then "const bar = static(foo)"
19:52:57FromGitter<akavel> :( ehhh, and I wanted to improve readability with PEGs :(
19:53:11Yardanicohttps://github.com/zevv/npeg also exists :P
19:53:14*marnix quit (Ping timeout: 240 seconds)
19:53:41FromGitter<akavel> oh oh oh oh oh!!!
19:54:20FromGitter<akavel> is it pure nim or requires some 3rdparty libs?
19:54:25Yardanicopure nim ofc
19:54:35Yardanicono dependencies
19:54:38Yardanico(except stdlib ofc)
19:54:50FromDiscord<Elegant Beef> Damn too quick yard i was going to go full pedant
19:54:54FromGitter<akavel> sweeeeet, thanks Yardanico!!! <3 <3 <3
19:55:14FromGitter<akavel> up for one more try ;)
19:55:55FromGitter<xmonader> hello :) new chapter of nim days covering parser combinators https://xmonader.github.io/nimdays/day21_parsec.html
19:56:04*vikfret quit (Quit: Leaving)
19:57:34FromGitter<akavel> lol, speak about timing: if npeg won't work for me, maybe I'll try parser combinators ;P
19:58:37FromGitter<xmonader> > lol, speak about timing: if npeg won't work for me, maybe I'll try parser combinators ;P ⏎ ⏎ I'm sure there're tons of optimizations in npeg one, this is merely to explain the concept :)
20:21:09FromDiscord<willyboar> @xmonader great!
20:21:39FromDiscord<SeanOMik> Is there a tutorial on making a .nimble file for a library?
20:21:52Yardanicojust do "nimble init"
20:21:59Yardanicoit'll create directory structure
20:22:09Yardanicohttps://github.com/nim-lang/nimble#libraries
20:22:09FromDiscord<SeanOMik> Okay
20:22:13Yardanicoand you can of course check other examples
20:22:19FromDiscord<SeanOMik> I've already created the directory structure
20:22:23FromDiscord<SeanOMik> So hopefully its correct
20:22:27Yardanicofor something simple it's just this
20:22:28Yardanicohttps://github.com/Yardanico/nim-mathexpr/blob/master/mathexpr.nimble
20:22:43FromDiscord<willyboar> Do you mean simple nimble file or nimble tasks?
20:22:45FromGitter<akavel> Yardanico: about npeg, after doing `const foo = patt ...`, I don't seem to be able to use it in another `patt`? :(
20:22:55Yardanico?
20:23:05Yardanicowhy do you want to use one patt in another patt?
20:23:10Yardanicojust create a "parser" then
20:23:29FromGitter<akavel> by parser you mean `peg`, yes?
20:23:32Yardanicoyes
20:23:54FromGitter<akavel> but then can I access sub-patterns from this parser?
20:24:23Yardanicowdym?
20:24:35Yardanicoit's PEGs but with nim syntax
20:24:37FromGitter<akavel> i.e.: I want to reuse some patterns in other patterns, but I want to have several separate patterns, not just one "overlord" pattern
20:24:50Yardanicowell it's not a "pattern"
20:24:52Yardanicoit's a whole PEG parser
20:24:57Yardanicopattersn are "a <- thing"
20:25:43FromGitter<akavel> Nim core's peg seems to allow reusing patterns :/
20:25:49FromGitter<akavel> my case:
20:26:03FromGitter<akavel> I want to declare a "helper" pattern pegUrlencoded
20:26:07FromGitter<akavel> which is non-trivial
20:26:16Yardanicobtw ping Zevv ^
20:26:22FromGitter<akavel> then I want to use it in a few places
20:26:24Yardanicoand wdym by "nim core's peg allows it"?
20:26:32Yardanicohow exactly?
20:26:51FromGitter<akavel> there are functions for composing Peg objects
20:27:08zedeusyou can use the grammer feature to define "sub patterns" i think
20:27:11zedeusgrammar*
20:27:18Yardanicoah right I forgot about that one
20:27:20zedeushttps://github.com/zevv/npeg/blob/master/src/npeg/lib/uri.nim
20:27:49Yardanicoexactly
20:28:03zedeushttps://github.com/zevv/npeg#composing-grammars-with-libraries
20:28:05zedeushere
20:28:56FromGitter<akavel> oooh, ok, thanks!!! <3 :) :)

20:34:29FromDiscord<SeanOMik> I have some questions about nimble project structure. My project will have this layout: https://media.discordapp.net/attachments/371759389889003532/724724009346007080/unknown.png
20:34:33FromDiscord<SeanOMik> Similar to it at least
20:34:51FromDiscord<SeanOMik> Will `foobar.nim` import everything in the `foobar` directory?
20:34:57Yardaniconot by default
20:35:02FromDiscord<SeanOMik> Okay
20:35:08FromDiscord<Isomorpheus> does `nimble install` not mutate your `nimble` file?
20:35:10FromDiscord<SeanOMik> What does `foobar.nim` actually have in it then?
20:35:15Yardanico@Isomorpheus why would it?
20:35:23FromDiscord<Isomorpheus> ever used npm?
20:35:28Yardanico@SeanOMik because you might want to split stuff into modules
20:35:37Yardanico@Isomorpheus nimble doesn't change anything in your project
20:35:48Yardanicoit only creates stuff in ~/.nimble (on *nix)
20:35:55FromDiscord<SeanOMik> And I do have stuff split into modules
20:36:05FromDiscord<SeanOMik> But I'm confused what I should put into `foobar.nim`
20:36:08Yardanicowell that's what it's useful for - you have a couple submodules and main submodule
20:36:18FromDiscord<SeanOMik> Oh okay
20:36:18Yardanicoor if you have a lot of separate submodules but want to export them all as one
20:36:29Yardanicoe.g. https://github.com/krisppurg/dimscord/blob/master/dimscord.nim
20:36:34FromDiscord<SeanOMik> Yeah, thats how may project is layed out
20:36:45Yardanicosorry https://github.com/krisppurg/dimscord/blob/devel/dimscord.nim

20:50:33FromDiscord<SeanOMik> I'm trying to generate documentation for my project but I get this error: ```Error: unhandled exception: pathutils.nim(70, 11) `not isAbsolute(f.string)` C:\Users\sean_\.nimble\pkgs\websocket-0.4.1\websocket.html```
20:50:45FromDiscord<SeanOMik> That `pathutils.nim` is not a file in my project
20:51:09FromDiscord<SeanOMik> `nim doc --project -o:docs/documentation.html src/project.nim` is the command I'm running
20:51:57FromDiscord<SeanOMik> Is there a way to not generate documentation for the websocket module?
20:52:29Yardanicoif you just want to generate docs for 1 file just do "nim doc -o:docs/documentation.html src/project.nim"
20:52:30AraqHmm, it’s caused by
20:52:30Araq future.cb = nil
20:52:46FromDiscord<SeanOMik> Okay
20:52:58Araqindicating that 'future.cb's refcount is off
20:53:12FromDiscord<SeanOMik> I'll just have to make a script to generate documentation for all my modules

21:20:08FromDiscord<gokr> I have a c2nim conundrum, the original header section I am wondering about is this: <https://github.com/gokr/orx/blob/master/code/include/math/orxVector.h#L67-L114> - as can be seen an orxVector is a struct of three unions. c2nim produced this: <https://github.com/gokr/orx/blob/master/code/include/math/orxVector.nim#L49-L89>. The reason I marked all the way to `pvVec.fX = fX` is because that code fails obviously because a Nim orxVECTOR has n
21:21:10*PMunch quit (Quit: leaving)
21:21:16FromDiscord<gokr> So AFAICT the C code uses the same struct type for cartesian, spherical, RGB, HSL and HSV spaces. No clue why though.
21:36:48*tane quit (Quit: Leaving)
21:55:53FromDiscord<gokr> So its apparently... a kinda C pattern I guess. Makes common code more readable, although... captures 5 different things in a single type.
22:16:49Zevvoh late to the party, anythig I can still help with, npegwise?

22:23:27FromDiscord<--HA--> Can walkFiles be converted to a sequence? I tried to use toSeq from sequtils on it but I'm either doing it wrong or that does not work.
22:27:11FromDiscord<--HA--> Oh. `toSeq(walkFiles("*")) `works but not `walkFiles("*").toSeq` which I kept trying. I guess because it is a template?
22:30:30FromDiscord<Recruit_main707> That’s weird
22:33:33FromDiscord<juan_carlos> toSeq is template
22:36:57FromDiscord<--HA--> So it is expected? Templates can not be used with the "." call?
