01:38:44FromDiscord<Elegantbeef> It's amazing that it works after 7 years give a lot of Nim code would explode in that time
01:45:22FromDiscord<bosinski2023> In reply to @janakali "On somewhat unrelated note,": seems theres a release 0.9 coming. was planned for 2023 and might surface this year 🙂
01:49:12FromDiscord<zumi.dxy> In reply to @Elegantbeef "It's amazing that it": Aporia...
01:49:37FromDiscord<janakali> 0.8 should be in most repos, but compiling vis from source is also easy: it only need lua54 and libtermkey

02:51:59FromDiscord<user2m> in nimscript createDir is not defined is there any other proc that can be used?
02:59:05FromDiscord<demotomohiro> In reply to @user2m "in nimscript createDir is": https://nim-lang.org/docs/nimscript.html#mkDir%2Cstring
02:59:33FromDiscord<user2m> In reply to @demotomohiro "https://nim-lang.org/docs/nimscript.html#mkDir%2Cst": Perfect!
03:34:27arkanoidI have a nim string, I have to pass it to an importec C function that wants a ptr cstring
03:34:51arkanoidI'm trying mystring.cstring.addr, but I get "expression has no address"
03:35:12FromDiscord<Elegantbeef> You cannot convert a Nim string to a `ptr cstring`
03:36:05FromDiscord<Elegantbeef> You can do `let x = cstring myString; myProc(x.addr)` but it'll likely not work how you intend
03:36:55FromDiscord<Elegantbeef> As I suspect it'll change the pointer `x` points to else it'd just be a `cstring`
03:37:09FromDiscord<Elegantbeef> There is a non zero chance this is actually a cstring array
03:40:33arkanoidmh, maybe I should skip the convertion from cstring to nim string initially, then. But I need to copy the cstring
03:40:48arkanoidlet newstring = cstring(oldcstring) would copy it?
03:51:25FromDiscord<Elegantbeef> No clue
04:00:04FromDiscord<demotomohiro> `let newString = $oldcstring` returns new string by copying from `oldstring`.
04:00:26FromDiscord<demotomohiro> And you can get `cstring` from `newString` later.

05:15:39FromDiscord<lx12ucy> thats true
05:20:46FromDiscord<m4ul3r> How would i determin if code is being compiled for 32bit or 64bit in a `when defined()` for code
05:23:24FromDiscord<Elegantbeef> The easiest is `sizeof(int) == sizeof(uint32)`
05:24:04FromDiscord<Elegantbeef> You can also do `defined(amd64)` or `defined(i386)` I imagine
05:24:40FromDiscord<pmunch> Sorry about that, seems like we where all asleep at the same time..
05:25:00FromDiscord<m4ul3r> That works

05:25:17FromDiscord<m4ul3r> thanks beef
05:29:09arkanoidremoving choosenim shims solved almost all the tooling problems I've been fighting for months
05:29:49arkanoidplease remove choosenim from nim download page, or possibly replace it with something that is tested with tooling
05:30:09FromDiscord<Elegantbeef> There is no replacement for it
05:30:15FromDiscord<Elegantbeef> gitnim only works on amd64
05:30:20FromDiscord<Elegantbeef> amd64 linux
05:30:27arkanoidwithout it is better than with it
05:30:39FromDiscord<Elegantbeef> Works on my machine TM
05:32:11arkanoidstart nimsuggest manually via choosenim shim from command line over random nim file, send sigterm to shim process (parent of real nimsuggest), now you have dangling nimsuggest process
05:32:47FromDiscord<Elegantbeef> I was joking, yes it's broke but it can be fixed
05:34:47arkanoidyes it can be fixed, but nim homepage points to a project with last release 6/2022, with pull requests and many issues waiting, and with main developer that has quit
05:35:42arkanoidhow many more bad points does it need to remove it from the official download page of Nim?
05:37:11FromDiscord<Elegantbeef> Well it should be forked and pointed to the official choosenim or w/e is decided on
05:38:44arkanoidremove from download page > fork fix and test > restore it
05:40:57arkanoidseriously, it causes OOM on dev machine with the right conditions. And the right conditions is using vscode and opening/closing projects. It accumulates and boom. Sometimes you trigger some nimsuggest bug that loops and fills heap and boom

06:10:45FromDiscord<Elegantbeef> You do also use nimlsp
06:10:58FromDiscord<Robyn [She/Her]> The OOM bug with nimlangserver was chased back to choosenim :p
06:11:06FromDiscord<Robyn [She/Her]> (edit) "chased" => "traced"
06:11:07arkanoidpmunch it depends how your development environment kills nimsuggest processes
06:11:24FromDiscord<Elegantbeef> Pmunch doesn't have nimsuggest processes 😛
06:11:27FromDiscord<pmunch> In reply to @arkanoid "seriously, it causes OOM": That's a nimsuggest bug though isn't it?
06:11:49FromDiscord<Elegantbeef> Apparently the shim does not properly handle it's processes and it causes a leaked program
06:12:05FromDiscord<pmunch> In reply to @Elegantbeef "Pmunch doesn't have nimsuggest": Well, NimLSP is basically nimsuggest with a mustache and fake glasses
06:12:19arkanoidpmunch: the long story https://github.com/nim-lang/langserver/issues/184
06:12:23FromDiscord<pmunch> If only a certain OS had symlinks..
06:13:04arkanoidthe short story is: choosenim proxy exes dont forward signals (sigtrap for example) to child processes properly
06:13:28FromDiscord<pmunch> In reply to @arkanoid "<@696333749570371585>: the long story": Well, what can I say NimLSP was purposefully design to avoid these issues 🤷‍♂️
06:13:33arkanoidas a result, you have leaking nimsuggest processes everytime nimsuggest proxy exe is launched
06:14:01FromDiscord<pmunch> I've gotta run now by the way
06:14:07arkanoidpmunch, that's why I've used nimlsp a lot
06:14:24arkanoidnimlsp is the winning design
06:14:51arkanoidbut nim gods promoted IPC and forking and stuff
06:14:59arkanoidand proxy exes
06:15:49FromDiscord<Elegantbeef> iirc the whole reason nimlangserver uses IPC is to manage phantom nimsuggest instances 😄

15:07:01FromDiscord<thesherwood> Looks like choosenim worked for `devel`. but i'm seeing the same error when i try to compile.

15:08:32FromDiscord<Robyn [She/Her]> In reply to @thesherwood "Looks like choosenim worked": What's the error?
15:12:15FromDiscord<thesherwood> I was wrong. Different errors on devel. Looks like most are coming from the package I'm using for clang. Pastebin: https://pastebin.com/raSFn1P3
15:12:52FromDiscord<Robyn [She/Her]> In reply to @thesherwood "I was wrong. Different": Ah, make sure you have wasi-sdk installed I think
15:14:04FromDiscord<thesherwood> I downloaded it and I've been running it on simple c programs. I think the simple nim program must be requiring stuff that my simple c programs aren't.
15:14:22FromDiscord<Robyn [She/Her]> Hm, what command line arguments did you give to clang on the CLI?
15:14:41FromDiscord<thesherwood> `nim c --cc:clang --cpu:i386 --nimcache:tmp --passC:"--target=wasm32 -O3 -flto -nostdlib -Wl,--no-entry -Wl,--export-all -Wall -o:nim_wasm6.wasm" nim_wasm.nim`
15:15:07FromDiscord<thesherwood> That's the nim command I've been using. When i compile the c programs I use the same clang options.
15:15:46FromDiscord<Robyn [She/Her]> Oh, try `--passL:"-lwasi-emulated-signal" --passC:"-D_WASI_EMULATED_SIGNAL"`
15:16:08FromDiscord<thesherwood> Both of those in the nim command?
15:16:30FromDiscord<Robyn [She/Her]> If you read through the paste, there's more arguments it says to pass to the linker and compiler I believe

17:00:29arkanoidI am wrapping imported C lib. I feel that there's room for a very powerful Nim macro here. All C lib functions are in the form "foo_r(ctx: Context, arg1: ..., arg2: ...)", at the moment I am passing around ctx for every call, it works but it is not very elegant
17:00:47arkanoidhow would you "hide away" that Context variable?
17:01:43FromDiscord<leorize> std/with
17:08:01FromDiscord<demotomohiro> Are you sure you never need to use multiple context?
17:15:04arkanoidleorize, thanks!
17:32:26arkanoidstd/with seems not working with left hand sides of assignments
17:32:48arkanoidwith ctx: let myfoo = foo_r(arg1, arg2)
17:33:26arkanoididentifier expected, but found 'let myfoo ='

18:16:04FromDiscord<Robyn [She/Her]> How should I install Nim on Windows? Choosenim is probably what I should avoid
18:18:30FromDiscord<Robyn [She/Her]> Think I got it
18:34:38FromDiscord<griffith1deadly> In reply to @chronos.vitaqua "How should I install": just download release from nim website, unpack and run finish.exe
18:45:09FromDiscord<Robyn [She/Her]> I cannot tolerate Windows for development
18:45:25FromDiscord<leorize> then why are you using it?
18:45:26FromDiscord<Robyn [She/Her]> I'm going to get WSL working just so I can get rid of this nightmare as soon as possible
18:45:31FromDiscord<Robyn [She/Her]> In reply to @leorize "then why are you": My mom's laptop
18:46:55FromDiscord<leorize> rip
18:47:03FromDiscord<leorize> your desktop still dead?
18:47:25FromDiscord<Robyn [She/Her]> Yep, couldn't fix it even after tinkering, the RAM seems to be fine so it must be the CPU or motherboard
18:48:03FromDiscord<leorize> that's unfortunate
18:48:09FromDiscord<Robyn [She/Her]> I accidentally got thermal paste on the pins of my CPU socket when trying to see if I put the CPU in wrong (I didn't, it has notches to ensure that) so now it's just unrecoverable
18:48:24FromDiscord<Robyn [She/Her]> Already stripped the drives and RAM from it if I decide to repurpose it for anything else
18:48:32FromDiscord<Robyn [She/Her]> In reply to @leorize "that's unfortunate": Yeaaah, but oh well, it's life
18:49:41FromDiscord<leorize> back when I didn't have my own computer I just carry with me a flash drive with a Linux installation
18:49:54FromDiscord<leorize> makes it easy to just use whatever computer in front of you
18:49:58FromDiscord<Robyn [She/Her]> I have a 32gb flash drive to be fair
18:50:35FromDiscord<Robyn [She/Her]> Wouldn't be a great experience though, so I'd probably get a bigger USB first
18:50:49FromDiscord<leorize> mine was on a 32gb \:p
18:51:03FromDiscord<Robyn [She/Her]> Didn't it clog up quickly?
18:51:11FromDiscord<leorize> but that's like 8 years ago
18:51:24FromDiscord<leorize> no, if you know your way around you can get quite some mileage
18:51:50FromDiscord<Robyn [She/Her]> Huh... Care to elaborate? I do not know my way around aha
18:52:09FromDiscord<leorize> first order of business is to use btrfs
18:52:24FromDiscord<leorize> then reduce the amount of writes by disabling all log writing
18:53:09FromDiscord<leorize> if you have the ram to spare, there are tools that synchronize your browser profiles to ram, avoiding expensive writes as you browse the web
18:53:12FromDiscord<Robyn [She/Her]> Isn't that the filesystem format everyone is raving about?
18:53:32FromDiscord<saint.___.> Why not just use an external ssd
18:53:45FromDiscord<saint.___.> They're super cheap
18:54:12FromDiscord<leorize> depends on your financial status, sure
18:54:21FromDiscord<Robyn [She/Her]> I am broke and have absolutely nothing to my name :p
18:54:26FromDiscord<saint.___.> Its liek $20 for a 200gb
18:54:32FromDiscord<saint.___.> O okay
18:54:41FromDiscord<Robyn [She/Her]> Trying to work on freelancing gigs but yeah kinda hard to start
19:00:34FromDiscord<sOkam! 🫐> Is there an existing way to create unix/linux signals from `signals.h`
19:01:23FromDiscord<sOkam! 🫐> _(other than wrapping the `signal()` function, that is. was wondering if there is something wrapped or idiomatic)_
19:02:13FromDiscord<leorize> wdym creating signals?
19:02:56NimEventerNew thread by AMSwift: Resizable arrays in Nim - difficulty in getting performance, see https://forum.nim-lang.org/t/11129
19:03:24FromDiscord<guzba8> In reply to @_deadmeme_ "is there any official/blessed": its been a bit since I last fought this, but I think adding your Downloads folder to the excluded folder list for Windows defender, then downloading choosenim to Downloads and installing from there helped? i remember disabling windows defender did not help, its just a disaster overall unfortunately
19:04:36FromDiscord<sOkam! 🫐> In reply to @leorize "wdym creating signals?": https://www.man7.org/linux/man-pages/man7/signal.7.html
19:05:16FromDiscord<sOkam! 🫐> maybe should have said "signal handlers" to be specific
19:05:45FromDiscord<leorize> there's no way out of using the syscalls, so wrap away
19:05:51FromDiscord<sOkam! 🫐> sent a code paste, see https://play.nim-lang.org/#pasty=QJLlZSEeYkiU
19:05:55FromDiscord<leorize> and you probably want sigaction instead
19:06:23FromDiscord<sOkam! 🫐> In reply to @leorize "and you probably want": whats the difference?
19:06:49FromDiscord<leorize> it's actually standardized and you can customize much more behaviors
19:07:09FromDiscord<leorize> you will also get the signal information in your handler as well
19:08:56FromDiscord<sOkam! 🫐> kk will look it up. first time using signals ever, im just referencing someone elses code for now until I understand the codebase
19:09:36FromDiscord<leorize> read man signal(7)
19:10:13FromDiscord<leorize> and signal-safety(7)
19:10:18FromDiscord<sOkam! 🫐> found this. seems useful. ty for pointing it out https://stackoverflow.com/questions/231912/what-is-the-difference-between-sigaction-and-signal/
19:10:35FromDiscord<leorize> signal handlers are never fun to deal with
19:11:07FromDiscord<sOkam! 🫐> why so?
19:11:42FromDiscord<leorize> they interrupts your code
19:12:02FromDiscord<leorize> ie. stop whatever is being done in your thread to run the handler
19:12:07FromDiscord<sOkam! 🫐> oh
19:12:14FromDiscord<leorize> as such they're even harder to deal with than threads
19:12:32FromDiscord<sOkam! 🫐> i believe this is just defining behavior for when the user Ctrl+C 🤔
19:12:44FromDiscord<sOkam! 🫐> is there a more idiomatic way to deal with that on nim?
19:12:58FromDiscord<leorize> setControlCHook \:p
19:13:12FromDiscord<sOkam! 🫐> definitely sounds like the right thing yep
19:13:16FromDiscord<sOkam! 🫐> ty leorize ✍️
19:13:33FromDiscord<leorize> though it's actually not any better, only a sugar and is also dangerous
19:13:54FromDiscord<leorize> at least the default impl won't try to allocate memory anymore iirc
19:14:09FromDiscord<leorize> you used to be able to deadlock your program on ctrl-c, pretty fun
19:15:12FromDiscord<leorize> but the rules of signal-safety still apply fwiw
19:16:14FromDiscord<sOkam! 🫐> i actually think that's what was happening 🙈
19:16:19FromDiscord<leorize> don't allocate memory, don't modify globals, and make sure you use the exact same subset
19:16:30FromDiscord<sOkam! 🫐> kk
19:16:47FromDiscord<sOkam! 🫐> sent a code paste, see https://play.nim-lang.org/#pasty=otmmOntyFvFf

19:17:43FromDiscord<leorize> it might come as a surprise, but exit is not async signal safe
19:18:42FromDiscord<sOkam! 🫐> so, this is very bad code? im just learning it for the first time, so no clue whts good/bad 😔
19:18:50FromDiscord<leorize> yep
19:19:14FromDiscord<leorize> and if you do it like this, none of your resources will be cleaned up properly, so you might have files that are not flushed to disk
19:19:24FromDiscord<sOkam! 🫐> oof
19:19:44FromDiscord<sOkam! 🫐> how do I exit correctly so everything is done well?
19:20:18FromDiscord<leorize> usually you trigger a flag to do that, atomically
19:20:27FromDiscord<leorize> then your code check if the flag is set
19:20:31FromDiscord<leorize> and if set, quits
19:21:13FromDiscord<leorize> quits by just returning and hope that your caller is also cancellation aware
19:21:46FromDiscord<sOkam! 🫐> hmm, so you would set a flag inside setControlCHook? is that what you mean?
19:22:20FromDiscord<leorize> pretty much
19:22:26FromDiscord<sOkam! 🫐> kk ✍️
19:23:10FromDiscord<sOkam! 🫐> can you pass data to the hook though? 🤔
19:24:58FromDiscord<leorize> not safely

20:17:19FromDiscord<leorize> probably not that bad \:p

22:25:45FromDiscord<Robyn [She/Her]> In reply to @toma400 "I'm sorry if this": In Nim, binary files are read as strings so you'd do it the same way you would with any text file
22:26:26FromDiscord<Robyn [She/Her]> Look into `std/streams` (specifically `newFileStream`) for what you want for your parser, too ^^ @TӨMΛ ☠
