00:17:27FromDiscord<codic> Is there a way to create a variable that can change it's type?
00:18:12FromDiscord<codic> using :untyped doesn't work
00:18:25Yardanicono
00:18:31Yardanicoyou need to use something like object variants for that
00:18:42Yardanicoor JSON module for simple stuff will also work (since it uses an object variant internally)
00:18:51Yardanicoand if you don't convert it to string there won't be any overhead really

01:30:15FromDiscord<Technisha Circuit> Is it faster to define a variable with the type specified?
01:30:34FromDiscord<Rika> faster in what way
01:32:17*chemist69 joined #nim
01:33:09FromDiscord<Yardanico> @Technisha Circuit unset in what way? GC automatically collects unused memory
01:33:40FromDiscord<Yardanico> And no, explicit types won't affect runtime at all
01:34:42FromDiscord<Yardanico> You really have to understand that all stuff like macros, templates, overloading, ufcs doesn't exist in the binary
01:35:02FromDiscord<Yardanico> It's all native machine code in the end, no types at all
01:36:14*dadada__ quit (Ping timeout: 256 seconds)
01:36:28FromDiscord<Yardanico> Types are a compile time (in Nim and backend language if it's not JS) thing
01:37:38FromDiscord<Technisha Circuit> Oh okay
01:37:40FromDiscord<Yardanico> That's why compiled programming languages with type systems are usually faster than duck typed interpreted ones - you don't have to do any type checking at runtime since you already know all possible types for everything at compile time
01:38:23FromDiscord<Yardanico> Well, that's not the only reason, but it still can affect the performance quite a lot
01:38:28FromDiscord<Technisha Circuit> Oh okay
01:38:44FromDiscord<Technisha Circuit> So why do most programming languages that are compiled require typing?
01:39:40FromDiscord<Yardanico> ???
01:39:40FromDiscord<Rika> you can write nim without ever touching a type, given that you dont write any procs w/ non-default args
01:39:57FromDiscord<Yardanico> There's also "auto"
01:39:59FromDiscord<Rika> the important thing is that the type does not change
01:40:12FromDiscord<Rika> @Yardanico cant auto args w/o default value xd
01:40:16FromDiscord<Technisha Circuit> Okay, thanks
01:40:17FromDiscord<Rika> or can you?
01:40:22FromDiscord<Yardanico> You can @Rika
01:40:23FromDiscord<Rika> i dont know actually
01:40:40FromDiscord<Technisha Circuit> Also, can i import a directory that isn't a package?
01:40:45FromDiscord<Yardanico> No
01:40:56FromDiscord<Yardanico> You can import packages from a directory though
01:41:01FromDiscord<Rika> how would that work tho...
01:42:06FromDiscord<Technisha Circuit> Hm
01:42:13FromDiscord<Yardanico> @Rika with auto it just assumes that the first call to the proc is the right one afaik
01:42:26FromDiscord<Rika> i see
01:42:38*dadada joined #nim
01:42:40FromDiscord<Rika> and if its not used it's DCE'd anyway

01:42:55FromDiscord<Rika> hm? really?
01:42:58FromDiscord<Yardanico> It's an implicit generic basically
01:43:01*dadada is now known as Guest85333
01:43:05FromDiscord<Technisha Circuit> How would i import all packages in a directory with that directory's name, so if `te.nim` was a file in `dir`, how would i do `dir.te.myFunction`?
01:43:24FromDiscord<Rika> i see lmao
01:43:51FromDiscord<Rika> you make a nim file with the same name as that directory that exports all files in the dir
01:44:03FromDiscord<Rika> (nim file outside the dir)
01:44:11FromDiscord<Yardanico> Fun fact - you could have implicit auto types in earlier versions

02:10:00FromDiscord<Rika> i prefer it

03:12:53leorize[m]I'd propose a way to generate typed dynlib objects
03:13:45FromDiscord<InventorMatt> is there a way to do word based operators? like using then as an operator so you could say: a then b

03:15:10leorize[m]@InventorMatt nope, only a specific set of keywords can be used
03:15:32FromDiscord<InventorMatt> okay, that's what I thought. thank you
03:15:34leorize[m]shashlick: my main concern would be the developer negligence of ABI breakage
03:15:41FromDiscord<Technisha Circuit> You could probably make it a thing with macros apparently
03:15:44FromDiscord<Technisha Circuit> Well
03:15:46FromDiscord<Technisha Circuit> I think
03:17:20leorize[m]shashlick: though I'm not sure if this would be in the scope of nimterop
03:18:05leorize[m]a typed dynlib object generator can be used for many other things (plugin systems?)
03:20:01shashlickokay can you please share your thoughts on that thread?
03:20:43shashlickcause this is related to https://github.com/nimterop/nimterop/issues/154 as well
03:21:27leorize[m]not really, this is much more flexible and target advanced use cases
03:23:02FromDiscord<Rika> leorize: eh? really?
03:23:09FromDiscord<Rika> you cant just backtick any word?
03:23:35leorize[m]you can backtick any word
03:23:42leorize[m]whether they will be treated as an operator is another story

03:25:29FromDiscord<Rika> i c
03:27:27shashlick@leorize: i already do something similar in the plugin system I made
03:28:13leorize[m]I pretty much expected that :P
03:29:41leorize[m]it's really just whether: should this be a nimterop thing, or can we build a general purpose system then hook nimterop into it?
03:30:00FromDiscord<Technisha Circuit> With NimScript could i make a dynamic command loader for Dimscord?
03:30:04FromDiscord<Yardanico> Yes

03:30:38FromDiscord<Technisha Circuit> What's the pros and cons for doing this?
03:30:40FromDiscord<Yardanico> But you'll have to handle all data transfer between host app and VM yourself
03:30:47FromDiscord<Technisha Circuit> Okay
03:30:50PrestigeFinishing up status bar integration: https://0x0.st/i9ch.png
03:30:53shashlicklike @kdheepak prototyped, it is easy to do in nimterop - question is how far to take it
03:30:54FromDiscord<Yardanico> Like you can't really pass complex types easily
03:30:58FromDiscord<Technisha Circuit> Oh
03:31:02PrestigeNeed to do some cose cleanup before I'll merge though, probably tomorrow
03:31:39FromDiscord<Technisha Circuit> I'd only need to be able to pass the `Message` type from dimscord and a sequence

03:41:47FromDiscord<slymilano> shiet
03:42:27FromDiscord<slymilano> now teach me to fish here i'd be greatful, the docs say: "proc removeSuffix(s: var string; suffix: string) {...}" by having it say `s: var string` the var tells me it's a direct modify function?

06:34:12FromGitter<bung87> well, most time they dont care much speed
06:34:40FromDiscord<Technisha Circuit> They tried making their Python library faster then most other libraries
06:34:52FromDiscord<Technisha Circuit> And it has the fastest http and async rn
06:35:17FromDiscord<Rika> and you say that they dont care about speed?
06:35:17FromDiscord<Rika> what
06:35:21FromDiscord<InventorMatt> Ability to compile easily is another huge advantage
06:35:40FromDiscord<Technisha Circuit> > and you say that they dont care about speed?↵They do but not from other languages
06:35:43FromDiscord<Technisha Circuit> I want to replace their http using Nim
06:35:49FromGitter<bung87> they can port python code very straightforward
06:35:49FromDiscord<Elegant Beef> It's extreme extensible
06:35:53FromDiscord<Technisha Circuit> And maybe their async implementation

11:00:56alehander92https://github.com/vedantroy/typecheck.macro willyboar PMunch
11:01:14alehander92maybe something like that was what i wondered about validators and web frameworks
11:01:23alehander92but i thought we can just do stuff like types + z3 require
11:01:36alehander92to generally want arguments that went through such validators
11:01:44alehander92(but autogenerating those also seems useful)
11:02:17alehander92still one can check that his arg didnt somehow arrive without the validator
11:02:37alehander92+ bung87 ^
11:02:43FromDiscord<uniminin> > no value then no that index↵@bung87[Gitter]#0000 wdym?
11:04:17PMunchalehander92, I guess that's similar to https://github.com/PMunch/jsonschema
11:05:07PMunchMy idea was to define routes using Nim types, and then register "parsing" middleware that will convert e.g. JSON to that Nim type.
11:05:11alehander92hm, i forgot about it
11:05:23*marquisdefalbala joined #nim
11:05:44PMunchAnd if you define a "view" (e.g. a HTML site) that pulls from multiple routes it won't actually go through creating/parsing JSON, it will just work directly on the Nim types.
11:05:45Guest19971opDispatch: I agree with PMunch .. definitely makes me more productive, the only other language I felt this productive with was python, and I may be even more productive, especially in the long term mainly due to macros and the power of automatizing tedious tasks
11:05:58alehander92yeah, and plugging this validation inside seems possible
11:06:56alehander92seems good, yeah
11:07:24alehander92btw that reminds me
11:07:37alehander92there are rest/graphql specs right?
11:08:49FromGitter<bung87> alehander92 seem can just translate it
11:10:14alehander92a nim web framework
11:10:26FromGitter<bung87> uniminin how you put a empty string to that position?
11:10:32FromGitter<bung87> from command line
11:10:48alehander92can also check automatically that graphql/rest api it supports works according to its spec similarly
11:10:56alehander92or even autogenerate
11:11:20alehander92those base paths+json schema def+controllers
11:11:26PMunchYeah my idea was to automatically generate documentation at least
11:11:30alehander92of them (leaving to the user to fill it)
11:11:37alehander92yeah, docs too
11:11:38PMunchBased on the types and docstrings given to routes
11:11:59alehander92yeah the other option is the opposite
11:12:06alehander92but maybe i am talking about openapi here
11:12:17PMunchGenerating an API based on a spec?
11:12:46alehander92yes
11:13:00alehander92bung87 what can be translate d
11:13:56FromGitter<bung87> hold on I release a new version, check what can I get by translating https://github.com/vedantroy/typecheck.macro
11:14:28alehander92mate
11:14:55alehander92:D
11:15:36alehander92kinda makes sense if you think about it
11:15:50alehander92but it's probably tied to typescript
11:16:05alehander92we should write own libs for metaprogramming
11:16:26alehander92because it's usually not easy to port even manually
11:17:31alehander92but yeah, your tool can do that :P

11:27:02FromDiscord<uniminin> where is paramCount from?

11:27:26FromDiscord<uniminin> thanks
11:27:29Yardanicoto get all params you either use commandLineParams or do
11:28:13Yardanicofor i in 1 .. paramCount(): echo paramStr(i)
11:28:31Yardanicoi because paramStr(0) is like in C - path of the binary

13:11:29PMunchDepends a bit what you want your plug-ins to do
13:11:40PMunchAnother option would be to use dll/so's

13:15:53PMunchIt's probably going to be harder to do, so the question becomes: "would anyone use this feature?"
13:20:06FromDiscord<Technisha Circuit> Well, even if no one uses that feature, it makes the game more modular so it's easier to test

13:31:32alehander92bung87 look it's a fine example, but i really dont think its a good target for your tool currently
13:32:12alehander92i think translating some real world dts files (e.g. for small popular libs)
13:32:22alehander92might be a good goal
13:32:33alehander92or some other small examples/libs code
13:34:38PMunch@Technisha Circuit, two things to keep in mind for using NimScript; 1. It's much slower than Nim, in a completely synthetic fibonacci benchmark I ran it was about 0.5x Python. 2. Getting data to/from the script is a bit painful and might slow it down even further.
13:34:50Guest43940xmltree/xmlparser doesn't work at compile time due to fopen, I think it would be sad if this is really the only reason for it not working

14:43:37disruptekI DIDN'T CHOOSE TO BE THIS AGE.
14:44:03PMunchWhat?
14:44:18disruptekhow old i am.
14:44:21disruptekit wasn't by choice.

14:56:37disruptekhow did we lose lemonboy?
14:57:05disruptekthis guy was smart.
14:57:26PMunchOh yeah, where did he go?
14:57:32disruptekD
14:57:49FromDiscord<Clyybber> hes gone inactive and then reappeared at zig :D
14:57:59disruptekoh, zig.
14:58:12disruptekthat's what i meant. 😁
14:58:28PMunchHmm, well that's a shame
14:59:29PMunchOkay, I've messed this up good somehow..
15:00:51PMunchOh wait, I know what I did in this case
15:01:15PMunchBut I still get crashes in multithreaded mode..
15:01:38PMunchSo annoying that I had something that worked..
15:01:49PMunchAlthough that could've been a super random fluke..
15:07:48*NimBot joined #nim
15:11:28bebarkerSince mutability of arrays in Nim is determined by declaration style (let/const vs var), is there a way to thaw and freeze arrays without copying? (thaw meaning make mutable, freeze to make immutable)?
15:11:36bebarkerjust curious
15:12:38leorize[m]if you access the variables directly, no
15:14:05leorize[m]though with a bit of wrapping magic this is possible, just not pretty
15:14:08FromGitter<brentp> is there a way to allocate a seq that's invisible to the garbage collector? I can `alloc` but then it doesn't know the length or cap.
15:15:07leorize[m]use --gc:arc
15:15:15alehander92PMunch what are you doing
15:15:36leorize[m]why are you trying to avoid the gc though?
15:16:32FromGitter<brentp> hmm. it's a callback from a C-api that's multi-threaded (in C). if I use any GC'ed object in there, it crashes.
15:16:47FromGitter<brentp> though you are right, it works fine to allocate with `--gc:arc`
15:16:54FromGitter<brentp> but not `--gc:refc`
15:17:24bebarkerleorize[m], I was thinking that might be the ticket, though in my current sleep deprived state I've apparently not thought of the exact incantation. I guess it involves working with refs
15:17:49*drewr joined #nim
15:18:05bebarkeralso i've just finished tut1 and probably missing something from tut2
15:20:14leorize[m]@brentp is the seq contained in the callback?
15:20:56FromGitter<brentp> yes. and if I use an array, all is well. as soon as i allocate anything, then it segfaults. i've had this problem before.
15:21:08FromGitter<brentp> ... but it works fine with --gc:arc
15:21:28leorize[m]run `setupForeignThreadGc()`
15:21:51leorize[m]arc won't have this issue, but it's still experimental
15:26:14FromGitter<brentp> @leorize. yes, that works ! thanks. now i have new issue that if I try to use the callback, I get ` Error: illegal capture 'map_fn' because 'process' has the calling convention: <cdecl>`
15:27:20leorize[m]your callback is trying to capture a variable from the outside
15:28:02leorize[m]closures and threads don't mix, so try not to :p
15:28:10shashlick@zacharycarter - nimterop should be faster now, made several perf improvements - please see if it helps

16:26:55shashlickZevv!
16:27:02shashlickHow do you profile in the vm
16:27:24disrupteklol
16:29:44Zevvshashlick: yeah thats fun.
16:30:04Prestigedisruptek: the guy that wrote lemonbar?
16:30:17Zevvtheres cpuTime() available but it is bogus unless you pass some flag, I was not allowed to put it in by mr A because he thinks people will do stupid stuff with it
16:30:52Zevvwhile he does allow tons of other stuff which can be used for way more stupid things
16:31:10disrupteklike pointers.
16:31:37disruptekBAN THE POINTER
16:31:44shashlickso i need to throw around a bunch of cpuTime() calls where I need to figure stuff out?
16:31:53Zevvright
16:31:54shashlickbut need a secret flag
16:31:58Zevvright
16:32:04Zevvthis is 2020
16:32:11Zevvyou want that kind of stuff, you do it yourself!
16:32:25Zevvcmon, really, no one want to profile the nim vm
16:32:29shashlickam watching Microsoft Build right now, don't ask
16:32:34Zevvwhy would you do such a thing
16:32:50shashlicki want to make sure the nimterop compile time stuff isn't too slow
16:32:52FromGitter<zetashift> nimterop will have dotnet support now
16:33:01shashlickalready threw out regex and sped it up by 20%
16:33:20Zevvwell, nim tells you how long it took to compile, thats one thing
16:33:28Zevvits 1-sample profiling
16:33:53*nekits quit (Quit: Ping timeout (120 seconds))

16:43:52*nekits joined #nim
16:45:11shashlickZevv: I just get undeclared identifier 'cpuTime' even with --benchmarkVM
16:45:45Zevvhm lemmesee
16:46:05shashlickokay i had to import times
16:46:27Zevvwell, there it is
16:48:12ZevvI think doing proper profiling in the VM should not be too hard to add. In the end it's just bytecode running in a VM, so it should be possible to get the VM instruction counter periodically and accumulate where time is spent, calculating the VM instructions back to their sources
16:51:07shashlickdo we already have a macro that can be pushed that measures proc execution time?
16:51:14shashlickfor all following procs
16:52:01Zevvnot that I know of
16:52:45Zevvalso, cpuTime is confusing to many people

17:07:58shashlickmeh - too much work to measure perf of each and every proc and macro one at a time
17:08:50PMunchalehander92, I'm writing a .so that is loaded in another program
17:09:06PMunchThe other program can call the `operate` procedure from any thread
17:13:40Zevvwhy is {.computedGoto.} disabled in the main VM loop?!
17:14:18AraqZevv: never tried to enable it, after I developed the feature I was burned out
17:14:48*brainbomb quit (Quit: Leaving.)
17:15:23Zevvwell, let me see how it blows up
17:21:19alehander92bung87 nice
17:21:27alehander92how would you deal with `_name` names
17:21:47alehander92PMunch yeah the setup foreign gc or something helped me a lot the other day
17:21:52alehander92not sure if applicable
17:22:07PMunchI've had that for ages
17:22:12PMunchSo it's not that
17:22:16PMunchThis is running in production
17:22:24PMunchSo it must've been something I've done in the latest iteration
17:23:41alehander92hm, so the diff doesnt help?
17:24:00PMunchWell, I think I know why..
17:24:07PMunchI have a global cache of things
17:28:00Zevvshashlick: I got a VM profiler running
17:28:06Zevvit's pretty trivial
17:30:29FromGitter<bung87> oh ,I make bug, I remove all `_`
17:31:36*natrys joined #nim
17:31:41alehander92but then
17:31:46alehander92you have to think of `_a` vs `a`
17:31:58alehander92`_a` are usually private fields
17:32:15alehander92you can think of naming convention
17:32:49FromGitter<bung87> a function startwith _ will not export (has`*` mark
17:33:46shashlickZevv: please share
17:34:42FromGitter<bung87> others I haven't take care.
17:35:17Zevvshashlick: it's pretty crude, but it works:
17:35:17Zevvhttps://github.com/zevv/Nim/pull/new/zevv-vm-profiler
17:35:31Zevvit shows you the top 16 CPU eating lines for each VM invocation
17:36:02ZevvTo make this usable I guess it will either need full annotation, or do inclusive accounting of the whole stack frames
17:36:04PrestigeHey PMunch, when using nimlsp if you make a change in one file, does it not register that the change was made in the other?
17:36:11Zevvbut all the info is there where it is needed.
17:36:14PrestigeTrying to figure out if it's a problem with my lsp client or not
17:36:25Zevvoh wait that's a pull request :)
17:36:30PMunchPrestige, what do you mean?
17:36:48Zevvshashlick: this one: https://github.com/zevv/Nim/tree/zevv-vm-profiler
17:36:58Prestigee.g. if I change the name of an enum in one file, and use the new name in another file, it will say the enum name doesn't exist PMunch
17:37:04Zevvhttps://github.com/zevv/Nim/commit/7c94d10fa4cfa323800965f64030886173d95633
17:37:10PrestigeI'll have to restart my lsp client and then it's fine
17:39:31shashlickZevv: so I am building with your changes - it will just print by default I guess
17:39:46shashlickprints a bunch of stuff while compiling nim itself :)
17:40:06PMunchHmm, that's odd
17:40:33*Jesin joined #nim
17:40:37Zevvshashlick: yeah you better make a nim_temp with that I guess :)
17:40:38PrestigeIt could just be my lsp client PMunch, just curious if you're seeing the same issue
17:40:56ZevvI'm seeing if I can make the output a bit more useful, 85% of the usage is now usually in the stdlibs somewhere
17:41:25Zevvlike iterators or tableimpl
17:43:34shashlickya, most of the output is stdlib itself
17:44:03Zevvideally I should add the time spent to all calls on the current stack frame
17:44:15Zevvso you get an inclusive list
17:44:25Zevvbut then again, I probably should not get started with this at all
17:44:58shashlickits picking lines like `when (NimMajor, NimMinor, NimPatch)`
17:45:21Zevvnah you are imagining things
17:45:23Zevvit's perfect
17:45:26Zevvit would never do that
17:45:32PMunchPrestige, pretty sure mine doesn't do it
17:45:57shashlickthat's what the line numbers correspond to
17:46:11Zevvyeah I know :)
17:46:32Zevvit's messy anyway. If one line emits 50 instructions, these 50 instrucionts are accumulated, but not the line total
17:47:07*Trustable quit (Remote host closed the connection)
17:47:52Zevvlet me see if I can make it target better
17:48:14shashlickwell these values are so low - 5.88e-06
17:49:24Zevvyeah time spent in 1 instruction. use a slower PC if you want them higher
17:49:44shashlicki will do anything for love, but i won't do that
17:52:47Prestigehm
17:53:05shashlickwish the OS procs like copyFile and getFileDate were available at compile time

17:59:02shashlickeven the slowest stuff in my code adds up to just 7ms, whereas the compiler takes 2 seconds from start to finish
17:59:30*narimiran joined #nim
18:00:35shashlickif I use --compileOnly, it goes down to 1.77sec
18:00:50shashlickso most of the time is in the compiler, not much I can do here
18:01:12Zevvyeah, but I'm *not* stopping with this now, you understand
18:01:38shashlickmy code is 2k, but Nim says 122k lines compiled, so ya its not really relevant
18:02:07Zevvyeah but it's compiling these lines to C
18:02:11Zevvnot running them in the VM
18:03:25shashlickya, i just wanted to see if my code was slow, but the 2sec goes way beyond what i'm doing
18:03:47shashlickthrowing out regex reduced the # of files to compile so that really helped
18:03:58Zevvfair enough
18:03:59shashlickunless i reduce the modules i'm using, this isn't going to get any better
18:04:22Yardanicook decided to clone all packages in nimble to try to build the dependency graph between then :D
18:04:24Yardanicothem*
18:04:35YardanicoI love osproc.execProcesses
18:05:11shashlickif i selectively import procs from modules, does that help compile time?
18:05:33ZevvI don't think so
18:08:25shashlickokay i'm done with this - cannot optimize this any more
18:08:38shashlickbut your change is very helpful Zevv, if you can add it to the VM, will be helpful
18:08:45Zevvyeah, and here I am obsessed with another project, profiling the Nim VM
18:08:46Zevvbwah
18:09:29ZevvI whish I had this when I was making NPeg. I spent way too much time scratching my head over performance
18:11:04shashlicknimprof helped greatly with runtime - got toast to run much faster
18:12:22Zevvyeah, thats the kidn of project where profiling really makes sense

18:28:53leorize[m]don't use cygwin
18:28:56leorize[m]it's evil
18:28:58leorize[m]go for native

18:30:06FromDiscord<codic> and i dont have admin here so no wsl
18:30:58leorize[m]uhmmm you can use mingw like a sane person...
18:31:10leorize[m]also cygwin is horrendously slow, use msys2 if you must
18:32:05livcddont use any of that
18:32:14leorize[m]also no, nim don't support cygwin, we just support native windows
18:32:14livcdjust use nim with mingw or whatever
18:32:37FromDiscord<codic> what's wrong with cygin though
18:32:45FromDiscord<codic> mingw is fine yeah but does it have a full shell
18:33:01leorize[m]yes, yes it does
18:33:10FromDiscord<codic> oh why does cygwin still exist
18:33:18leorize[m]cygwin is a posix compatibility layer on top of windows
18:33:21leorize[m]it's not for "I want a shell"
18:33:29livcdwhy does leorize[m] exist
18:33:32livcdsame question :P
18:33:36leorize[m]it's for "I have this posix thing and I wanna run it without modification"
18:33:46leorize[m]source modification*
18:34:54leorize[m]though I'd say that msys2 provide a better environment than cygwin regarding posix compat (mainly because it has pacman) :P
18:35:03FromDiscord<codic> does mingw have pacman?
18:35:12leorize[m]if you want latest gcc, msys2-mingw64 provides it
18:35:15livcdwhy do you need pacman?
18:35:26FromDiscord<codic> i'm used to t
18:35:28FromDiscord<codic> (edit) 't' => 'it'
18:35:36leorize[m]installing dependencies in my case
18:35:48leorize[m]I wrote a cross-platform gtk app (yes, yes it's horrifying)
18:36:14FromDiscord<codic> why not just use qt if you wanan go coss platform
18:36:30leorize[m]do you see a qt binding for nim?
18:37:53FromDiscord<codic> qml binding yes, but how was I to know that you made the app in nim in the first place? :P
18:37:56FromDiscord<codic> Also ignore the typos
18:39:34FromDiscord<codic> i dont use arch btw
18:41:57shashlickmsys has pacman

19:13:48dadadaI think a feature that would parsing in macros more lenient would be cool, ie. a pragma you can set for macros, so that discards aren't needed infront of procs that return values, and the like
19:13:54dadadas/would/would make
19:14:27dadadamacros are after all code generating code, and not the actual code...
19:15:05dadada(the discard example applies only to typed macros I think)

19:32:36leorize[m]dadada: it'd be better if we have some context on what you're doing
19:33:53dadadaleorize[m]: I'm developing a lot of macros, most of the time I'm happy, but sometimes the parser trips up on something, it should simply ignore, since the macro writes the code and AFAIK the parser doesn't
19:35:15leorize[m]the parser makes the AST :p
19:35:49dadadayeah, but couldn't he be a bit more lenient when creating the AST when parsing for a macro instead for the actual compiler
19:35:55dadadaI show you something:
19:36:24dadadahttps://play.nim-lang.org/#ix=2mK1
19:36:30dadadaso it trips up because the proc has no identifier
19:36:48dadadabut my macro will rewrite the code anyway and create a special identifier
19:37:13dadadawhat's the point of expecting perfection in the code part of a macro? the macro is the one who should clean that input and bring it there
19:38:19leorize[m]it's about whether the compiler even know how to make the AST :)
19:39:05leorize[m]it can't give you AST if it doesn't know how to create it for that case
19:39:06dadadaall it needs to do is to leave out the name identifier of the ProcTy and I'm happy
19:39:43leorize[m]well, please open an RFC requesting that :P
19:40:06dadadarequest? demand! :P

21:40:03FromDiscord<mratsim> I have to post the code and write the blog though
21:40:53FromDiscord<mratsim> the thing I don't understand is why I have a 21x speedup on both Weave and OpenMP while I only have 18 cores

21:42:14dadadahas someone written a beautifier for the ref object default output you get with repr?

21:54:21dadadamratsim: I want to keep my eyes for a while, so I won't :-D
21:55:49FromDiscord<mratsim> everytime I work with tables or variants in macros which is often when i need to do slightly complex things, this kills me a little
21:56:02Yardanico@mratsim runtime repr for tables looks worse tbh :P
21:56:28FromDiscord<mratsim> btw, were all the tables corner perf issues fixed?
21:56:43FromDiscord<Clyybber> we have a new hash if you mean that
21:56:56FromDiscord<Clyybber> and its improved the performance quite a bit
21:57:11FromDiscord<Clyybber> btw, genericReset is now gone
21:57:28dadadawhy do our tables allow to have multiple keys with the same key value

21:58:08Yardanicolol
21:58:09dadadaI mean, you can simply insert a seq when you want multiple values for a key ...
21:58:32dadadano, I still don't want the answer :-)
22:01:52dadadamratsim: let's congregate to make a better repr
22:02:25Yardanicofwiw repr with --gc:arc is a better than without it

22:04:32FromDiscord<mratsim> ahI see
22:04:46FromDiscord<mratsim> it's the commit not the PR
22:05:06dadadaYardanico: the code is pretty short, ey... did the format change or just the formattingß

22:06:17leorize[m]dadada: the answer for why tables can do multiple val per key without a seq is really simple, if you wanna know, that is
22:07:17dadadaleorize[m]: okay, if you can put it into one line, I'll hear

22:09:27dadadatrue
22:11:41dadadaYardanico: new repr looks better, why isn't it enabled for non-arc?
22:11:44*Trustable quit (Remote host closed the connection)
22:12:15Yardanicodadada: idk honestly, but new runtime stuff (destructors, arc, etc) changed quite a lot of things
22:12:43Yardanicoseqs/strings are represented differently with arc as well
22:13:07Yardanicohttps://github.com/nim-lang/Nim/blob/devel/lib/system/seqs_v2.nim https://github.com/nim-lang/Nim/blob/devel/lib/system/strs_v2.nim
22:13:31dadadahmm, new repr doesn't put " around string vals, I think that's a regression, makes it harder to spot strings
22:13:57Yardanicoyou can try it yourself easily btw
22:14:11Yardanicoarc is available on 1.2.0, although there are quite a lot of fixes in devel for it
22:14:52shashlickYardanico - do you know when https://github.com/nim-lang/Nim/issues/14251 will be fixed
22:15:00FromDiscord<Clyybber> dadada: Hmm, good point. I'll fix that
22:15:02Yardanicoshashlick: honestly I don't :D
22:15:27Yardanicoalso https://github.com/nim-lang/Nim/issues/14383 (see a comment there)
22:15:38Yardanicoshashlick: a workaround would be to remove inline pragmas
22:15:39FromDiscord<Clyybber> dadada: The newruntime repr works with the old runtime too with a tiny fix
22:15:46Yardanicoin some places
22:15:49Yardanicofor nim-regex that is
22:15:54shashlickcode is in regex though so I cannot do anything
22:16:16shashlickblocks me with trying arc in nimterop
22:17:01Yardanicowell you can patch nim-regex locally to test arc locally :D
22:18:17dadadaClyybber: are those empty seeming hcode 0 things indicating reserved memory or why do the yneed to be displayed 100 times?
22:18:26Yardanicoyes it's reserved
22:18:38FromDiscord<Clyybber> Clyybber: Not sure what you are referring to
22:18:42Yardanicosee https://nim-lang.org/docs/tables.html#defaultInitialSize
22:18:43FromDiscord<Clyybber> repr ing tables?
22:18:50dadadayes
22:18:56Yardanicodefault initial size for tables is 64 entries
22:18:58Yardanico^ by that const
22:19:00dadadathe link Yardanico sent me comparing repr versions
22:19:02Yardanicoyou can change it youtself
22:19:09YardaniconewTable[string, string](size)
22:19:11FromDiscord<Clyybber> Thats expected, repr prints *everything*
22:19:18Yardanicoand it has to be power of two of course
22:20:38dadadaClyybber: I appreciate that but couldn't a syntax be found that waits until the next non-reserved memory thingy, and then flushes a summary 40*(hcode: 0, key, val: )
22:21:19Yardanicodadada: that's overengineering in my opinion
22:21:55Yardanicowell you can always make a PR :P
22:22:21dadadaYardanico: in mine developing software should be an activity that doesn't create unending headaches, the developer deserves just as much eye candy as everybody else
22:22:29Yardanicorepr is not for eye candy
22:22:32Yardanico"echo x" is for eye candy
22:22:47*someunknownuser quit (Quit: someunknownuser)
22:23:46FromDiscord<Clyybber> dadada: Yeah, but $ is for eye candy, repr is to inspect the internal structure
22:23:51dadadathere are situations where echo x doesn't work and then you want to still understand your data
22:24:06FromDiscord<Clyybber> then you should write some custom proc for that
22:24:10Yardanicothen define `$` for that type :P
22:24:17FromDiscord<Clyybber> because there is no one size fits all solution
22:24:22dadadaYardanico: incidentally I'm writing something that should work for all types
22:24:30Yardaniconice
22:24:41dadadaand getting the address of things is appreciated actually
22:31:06FromDiscord<Clyybber> dadada: Fix for strings and chars is up: https://github.com/nim-lang/Nim/pull/14400
22:31:35Yardanico~stream
22:33:24dadadaClyybber: duuude, awesome! I haven't tested it but it looks like this new format is much closer to being parseable by Nim's own parser, I think it's a no-brainer that this should be made possible, I'd love to use a macro and parseExpr to extract Info from a repr or to reformat the way I want it
22:34:07dadadasorry for using "no-brainer" buzzword :-(

22:55:57Yardanicowell nim-regex itself works
22:56:07Yardanicobut with some iterators from other modules it doesn't

23:02:33Yardanico0.11.2 is almost 1 year old, yeah :D

23:06:39zedeusthis rewrite causes it https://github.com/nitely/nim-regex/commit/0570009fe6cd7c9131716bb78223e9f5dfcb05a9
23:07:04*couven92 quit (Quit: Client Disconnecting)
23:08:04Yardanicowell yeah, but I don't think it's good to track it in the nim-regex itself
23:08:13Yardanicoit's better to be fixed upstream since it's not really specific to nim-regex :P
23:08:36Yardanicoand as I said you can fix it temporarily if you remove some inline pragmas from nim-regex's funcs
23:08:42zedeusof course, such a huge commit doesn't help tracking it down anyway
23:08:57zedeus61 procs are inlined, "some" is a bit vague lol
23:08:58Yardanicowell I had to minimize it from the whole src of nim-regex to ~30 lines :)
