00:56:07arkanoidmh, I'm using "chronos" lib in my project. It compiles and works correctly, but nimsuggest/nimlangserver keeps complaining that "cannot evaluate at compile time: result" in "error "Error", host = server.host, error = result.error". How can I convince nimsuggest that that line is ok?
00:56:25arkanoidsorry, not chronos, but chronicles
00:56:33arkanoid(the logging one)
00:56:58FromDiscord<Robyn [She/Her]> In reply to @arkanoid "mh, I'm using "chronos"": Restart VSC and kill any Nimsuggest processed
00:57:39FromDiscord<Robyn [She/Her]> Unfortunately it's a known bug, should probably report it in case though
00:58:11arkanoidno, it is repeatable. I keep receiving it even after nimlangserver/nimsuggest/vscode restart
01:03:28FromDiscord<Robyn [She/Her]> Hm... Odd then

01:24:16FromDiscord<awesome3434> In reply to @Elegantbeef "Probably best to do": I'm not sure about this, but I think it will lead to the same issue?
01:24:49FromDiscord<Elegantbeef> I don't even know what you're trying to solve
01:25:03FromDiscord<Elegantbeef> I don't use C++ so don't know why it requires an attribute for interop
01:26:14FromDiscord<Elegantbeef> Though with the closure macro you could use `emit` or `codegendecl` to emit your own type
01:28:31FromDiscord<awesome3434> In reply to @Elegantbeef "I don't use C++": Basically I can't put any object that doesn't have the attribute within the function that requires it (which is required for any object that isn't primitive)
01:29:24FromDiscord<Elegantbeef> And you cannot just wrap a Nim object with a C++ object?
01:29:30FromDiscord<awesome3434> Also it's not really much of a library but a custom compiler with own attributes
01:30:05FromDiscord<awesome3434> In reply to @Elegantbeef "And you cannot just": But Nim will still put it's own object within the C++ code, right?
01:30:09FromDiscord<Elegantbeef> Sounds like a CGPU compiler 😄
01:30:12FromDiscord<Elegantbeef> Right
01:30:33FromDiscord<awesome3434> In reply to @Elegantbeef "Sounds like a CGPU": To be more precise Cheerp
01:30:38FromDiscord<Elegantbeef> You cannot control the Nim code generation for everything that requires forking the compiler
01:31:20FromDiscord<Elegantbeef> Why do you even need to send closures across a bridge
01:31:34FromDiscord<Elegantbeef> Atleast I assume these attributes generate interop code
01:33:05FromDiscord<Elegantbeef> If this is for JS interop you should just send all your ref objects as `ptr object` and not send closures to the JS side
01:34:49arkanoidis switch("stackTrace", "on") compatible with release mode?
01:35:15arkanoidI'm trying to use https://nim-lang.org/docs/estp.html but all I get is "Entry: 1/1 Calls: 3544/3544 = 100.00% [sum: 3544; 3544/3544 = 100.00%]"
01:36:04FromDiscord<Elegantbeef> Using nimprof is sorta meme as a lot of software 😄
01:36:30arkanoidmh, ok, I'll switch to something else then
01:36:39FromDiscord<Elegantbeef> I suggest using hotspot
01:36:53FromDiscord<Elegantbeef> It's a nice gui program built ontop of linux's perf
01:37:27FromDiscord<Elegantbeef> But to use the nim profiler I believe you need `stackTrace` `lineTrace` and `profiler`
01:38:22arkanoidI'm compiling with switch("profiler", "on") and switch("stackTrace", "on")
01:38:47arkanoidthis page https://nim-lang.org/docs/estp.html does not reference lineTrace
01:39:24FromDiscord<Elegantbeef> Yea I played with the profiler briefly to generate a flamegraph
01:39:28FromDiscord<Elegantbeef> So I think you need all three
01:40:44FromDiscord<awesome3434> sent a code paste, see https://play.nim-lang.org/#pasty=FvAHfvPrYbMx
01:40:56arkanoidwell, I'm installing hotspot, now I need to recap how to run perf

01:41:43FromDiscord<.bobbbob> sent a code paste, see https://play.nim-lang.org/#pasty=PuhbmdveJoti
01:42:47arkanoidcan't run perf as ubuntu makes a mess with kernels
01:43:25FromDiscord<awesome3434> In reply to @Elegantbeef "If this is for": I'm not really sure what you meant by that
01:44:14arkanoidok, recording
01:44:45FromDiscord<Elegantbeef> Why do you need to have the attribute if you don't generate JS code?
01:44:47arkanoidbut I guess I sould compile release but with debug symbols
01:46:36FromDiscord<awesome3434> In reply to @Elegantbeef "Why do you need": Though I have to use DOM API later which makes it inevitable to have it
01:48:17FromDiscord<Elegantbeef> Don't call the dom API 😄
01:49:28FromDiscord<awesome3434> In reply to @Elegantbeef "Don't call the dom": Nice tip, thanks
01:49:39FromDiscord<Elegantbeef> Jokes aside we have nim -\> js
01:50:17FromDiscord<awesome3434> Although It doesn't seem to provide any WASM support
01:51:38FromDiscord<awesome3434> (which in my case both are needed)
01:52:09FromDiscord<Elegantbeef> So write frontend in Nim then call that from wasm
01:52:26FromDiscord<Elegantbeef> Maybe speak to @jmgomez though given his UE work he might help
02:02:04FromDiscord<awesome3434> In reply to @Elegantbeef "So write frontend in": Uhh, Cheerp handles everything on it's own, including bridging, so now it'd be quite a nonsense having set-up everything from the bottom in JS, I really thought it could be easily solved with a few lines of code considering Nim is quite a powerful language with lots of comp-time reflections
02:02:25FromDiscord<awesome3434> to set-up
02:06:34arkanoiddo you know how can I compile release but with debug symbols?
02:07:02FromDiscord<Elegantbeef> `--debugger:native`
02:07:27arkanoidthanks
02:12:53arkanoidmh, perf.data generated with --debugger:native is "not readable" according to hotspot
02:15:40arkanoidmy fault, it was a permission problem

04:14:54FromDiscord<leorize> looks like that site requires JS to render
04:15:03FromDiscord<leorize> which means you can't scrape using a simple http client
04:15:55FromDiscord<dysrakescence> I'm new to web scraping but I heard that I would probably need something like a browser header or something?
04:16:10FromDiscord<leorize> for this you don't need headers
04:16:13FromDiscord<leorize> you need a browser
04:17:38FromDiscord<dysrakescence> is there a std library that I can use to scrape the site?
04:17:44FromDiscord<leorize> no
04:18:30FromDiscord<leorize> this is not really a website, it's an application
04:18:58FromDiscord<leorize> there are two paths to this\: either you figure out their API endpoints and use it to obtain the raw data that they use to render their pages
04:21:21FromDiscord<leorize> or just use a headless browser to render the page then download the result

20:21:07FromDiscord<djazz> can you modify the generated C code manually and add the attributes, does it work then?
20:21:16FromDiscord<djazz> to see if its actually possible
20:25:39FromDiscord<djazz> It would also be interesting to look at decompiled wasm module how its calling across and generating code

20:37:15FromDiscord<awesome3434> Haven't tested that yet tho
20:38:43termerHow do people compile Nim to wasm these days
20:39:39FromDiscord<Elegantbeef> emcc or wasi-sdk
20:39:44FromDiscord<Elegantbeef> Though you can also use clang directly
20:40:31termerI mean how do you set it up to use that
20:40:39termerI know of emscripten
20:40:54FromDiscord<Elegantbeef> https://github.com/beef331/wasm3/blob/master/wasmsources/config.nims
20:41:47FromDiscord<Elegantbeef> If you use clang directly you need to set the linker to wasm-ld or w/e it's called
20:41:49termerThis could probably be made an official build target fairly easily
20:42:00FromDiscord<Elegantbeef> It's all just fiddling with configs so yea
20:42:39FromDiscord<Elegantbeef> Should just be forking the default compiler config for `defined(emscripten)`
20:42:46FromDiscord<Elegantbeef> then you should be able to do the same as `-d:mingw` on linux
20:42:59termerThat would be really beneficial to do
20:43:07termerI don't think Araq likes wasm for some reason though
20:43:29FromDiscord<Elegantbeef> Would also be nice to get a `-d:clangwasm` 😄
20:43:34termerYeah
20:43:39termerI think using the JS target when you're building something for modern browsers when you could just use wasm
20:43:39FromDiscord<Elegantbeef> Since most people have clang in their path
20:44:35termerwhat the fuck is "quirky" for --exceptions

20:49:41termerLOL why is it an option

21:10:12FromDiscord<Elegantbeef> Ah you're on mac
21:10:39FromDiscord<Elegantbeef> Best way to cross compile Nim is to use zigcc
21:12:30FromDiscord<v_e_c_k> zig? i've experimented with that, too -- it and Go seem to cross-compile effortlessly (experimenting with Rust -- the CentOS trick worked, IIRC) -- so zigcc -- I can look for info, but have any favorite links?
21:13:02FromDiscord<Elegantbeef> `nim c -d:release --cc:clang --clang.exe:zigcc --clang.linkerexe:zigcc --passC="-target x86_64-linux-gnu.2.19" --passL="-target x86_64-linux-gnu.2.19"` should work

23:43:31arkanoiduser nickysn on github just found the root of the problem that has been haunting nim+nimsuggest+nimlangserver for YEARS. And the cause seems to be choosenim + shims. https://github.com/nim-lang/langserver/issues/184#issuecomment-1969415140
23:44:13arkanoidI see the light!
23:44:13FromDiscord<saint.___.> That seems promising
23:44:57FromDiscord<Elegantbeef> lol
23:45:30FromDiscord<Elegantbeef> That's crazy silly that it's the culprit
23:48:24arkanoidmy initial tests seems to prove that
23:48:44arkanoidand I know this problem so well that I have a global keyboard shortcut that calls "kill nimlangserver"

23:53:30arkanoidhow many people use choosenim for running nim+nimsuggest? How is possible that this issue went unseen for so long time?
23:54:19FromDiscord<Elegantbeef> Many people use choosenim
23:54:26FromDiscord<Elegantbeef> Infact I use choosenim and nimlangserver(with kate)
23:56:17arkanoidmaybe the issue is due to how vscode nim extension deals with choosenim shims
