03:10:19FromGitter<gogolxdong> anyone used websocket? ⏎ `socket went away, close code: 1002, reason: Masked frame from server`
03:16:08FromGitter<gogolxdong> > You cannot just "echo" the buffer you received. The RFC says, that frames from client to server must be masked. It doesn't say that messages from server to client must not, but at least for Chrome it shouldn't. Hence, if you want to echo data, you have to decode (unmask) the frame and construct a new one. The payload needs to be XOR'ed byte-by-byte with the mask key.
03:17:24FromGitter<gogolxdong> It's the problem of chrome. Firefox is fine.
03:22:23FromGitter<gogolxdong> ah ,there is a trigger websocketUnmaskedByDefault.

04:02:04kinkinkijkinalright, I'm gonna do a fixed-depth tree solution that is going to be very painful to look at
04:02:23kinkinkijkinbut I think it fits this project the best at my current level of knowledge
04:08:56kinkinkijkinvar tree = newSeq[tuple[dlev:uint16,chns:seq[tuple[chan:uint16,lins:seq[string]]]]](0)

06:59:46Araqleorize, reJoined is not a test failure, it means the test is covered by the "megatest" category
07:00:57leorizethen maybe it should not be written as FAIL in testresults.html
07:01:19Araqoh, most people only look at the console output
07:01:36AraqI probably forgot to update the logic in testresults.html, good point
07:02:23leorizeand I think the `--targets` switch is broken
07:02:47leorizeI use `tester --targets:'c c++' all` and JS tests still attempted to run

13:34:27FromGitter<yglukhov> Araq: thinking about adding `nimsuggest` to `installDirs` in `compiler.nimble` to allow using nimsuggest as a nimble-installed library (e.g. in nimlsp). Any objections?

13:37:55FromGitter<yglukhov> cool
13:38:24PMunch+1
13:48:25PMunchAraq, how does Nim find the `lib` folder?
13:54:07FromGitter<Clyybber> Araq: Is it intended that stuff like this fails: ```const a = [] ⏎ ⏎ for e in a: ⏎ echo e ⏎ ... [https://gitter.im/nim-lang/Nim?at=5c18fbff34c6c32cc8344692]
13:54:53*vlad1777d joined #nim
14:00:15leorizePMunch: ../lib relative to the Nim binary folder
14:01:56PMunchHmm, when you use choosenim though "which nim" results in "/home/peter/.nimble/bin/nim" while lib is at "/home/peter/.choosenim/toolchains/nim-0.19.0/lib"
14:02:13PMunchIIRC the nim binary there is just a proxy to the actual Nim file
14:03:25PMunchI guess it could try to parse the output of "choosenim show", and if choosenim isn't installed the default to "`which nim`/../lib"
14:03:25leorizeit follows symlink
14:03:31PMunchNo it doesn't
14:03:48leorizeit does, because that's how I packaged Nim for Haiku?
14:03:53*nsf quit (Quit: WeeChat 2.3)
14:04:08PMunch`which nim` points me to a binary file
14:04:09leorizeoh, unless you mean `which` doesn't follow symlink :P
14:05:52PMunchThe file /home/peter/.nimble/bin/nim is not a symlink
14:06:10PMunchhttp://ix.io/1wi3/
14:06:26PMunch`wtf` is an alias for which, type, and file by the way
14:08:03leorizeguess it's far more complicated than I anticipated
14:08:21FromGitter<SolitudeSF> choosenim generates a proxy which launches nim
14:08:21leorizethere's `findNimStdLib()` in compiler/nimeval, but I suspect it's not used
14:10:04PMunchYeah, but that does pretty much the same as you suggested
14:10:13PMunchFind the `nim` binary and go up a folder
14:10:20PMunchIt returns "" for me
14:10:43PMunchhttp://ix.io/1wi4/Nim
14:10:53PMunchThat prints an empty string

14:48:47FromGitter<xmonader> Publicity wise too ^
14:51:18PMunchWell you would need to dig up a lot of information

18:01:39FromGitter<Vindaar> I've been thinking about the json `%*` macro. Since `JObject` keys are strings anyways, wouldn't it be nice if one could leave out the `"` around the keys (as long as the key is a valid ident of course)?
18:01:58FromGitter<Vindaar> It's probably a bad idea for some reason I haven't thought about :)
18:03:02FromGitter<alehander42> sounds good to me, as `js{..}` already does that iirc
18:08:07FromGitter<Vindaar> which `js{}` do you mean?

19:34:53FromGitter<alehander42> @mratsim nice, I just wanted to generate stuff based on sitcom scripts these days
19:35:23FromGitter<mratsim> basically what is missing is a way to save the model and some CLI commands
19:35:37FromGitter<mratsim> then we can run it on the Nim repo, and generate Nim code :P
19:56:48FromGitter<xmonader> @mratsim congrats! currently i'm doing machine learning courses hopefully I can get the inners of your code someday :)
19:57:14FromGitter<xmonader> @leorize did I read that correctly? you're building Nim on Haiku-os?
19:57:30leorizeyep
19:58:01FromGitter<xmonader> I had that idea yesterday! and I didn't bother because it's not posix, correct?
19:58:23Araqit's posix'ish
19:58:33Araqand posix is an illusion anyway
19:59:03Araqin reality there is a bunch of unixes that and posix is the half-assed C specific common subset of these
19:59:07*nsf quit (Quit: WeeChat 2.3)
19:59:35FromGitter<xmonader> @Araq it's a single user system (afaik) so i won't be surprised if there lots of APIs (e.g osproc) not available no? (to compile nim for linux targets at least)
19:59:58*floppydh quit (Quit: WeeChat 2.3)
20:00:23Araqosproc works, Nim uses it extensively and can bootstrap on Haiku
20:00:36leorizexmonader: only selectors got some APIs missing
20:00:55leorizeeverything else works
20:01:05FromGitter<xmonader> @Araq @leorize that's great news
20:01:21FromGitter<xmonader> Also is there a specific reason investing on Haiku? is it an official effort?
20:01:44leorizebecause I ported it :P I'm a HaikuPorts maintainer :)
20:02:08Xeoff topic, but is haiku capability based?
20:02:13FromGitter<xmonader> Oh! great job leorize! I've it on a VM maybe i tinker a bit later
20:02:50leorizeXe: not yet, that is, if they decide to move in that direction
20:02:57Araqfwiw I ported Nim to Haiku before leorize took over
20:03:03Araqso in this sense it's "official"
20:05:02FromGitter<xmonader> @Araq not until a link available on the download pages on nim website :P
20:07:08Araqwow somebody on HN agrees with me https://news.ycombinator.com/item?id=17441773
20:07:45AraqI know you don't wanna hear it but Haiku should avoid "package management" and /usr/bin crap and then I'll reconsider using it
20:08:16FromGitter<xmonader> @Araq wow is that the first time people agree with you?
20:08:38FromGitter<xmonader> I'm totally against system-wide package managers (nixos/guix ftw!)
20:09:10Araqxmonader: it's the first time I read a post like that

20:09:20ldleworkI'm sure of it

20:09:43FromGitter<xmonader> https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/compilers/nim/default.nix interesting they have 0.18 there
20:10:02ldleworkeven if it isn't, Nim is easy to compile
20:10:55Araq> What happens when one library, used by 6 of your installed applications, has a security flaw? You need to update all 6.
20:11:02FromGitter<xmonader> actually automated bundler with AppImage for nim binaries can be a good project
20:11:18Araqyeah, that process is called "automization" and computers are good at it. jezz...
20:11:27Araqer
20:11:34AraqI think in English it's "automation"
20:11:38Araqbut you get the idea ;-)
20:11:41ldleworksomeone should write a buildNimApplication and buildNimLibrary helpers for nixpkgs
20:11:51ldleworkto help adoption of Nim within the Nix community
20:12:02leorizexmonader: Haiku's package manager can install both in home prefix and system prefix ;)
20:12:04ldleworkI don't think anyone has done it.
20:13:59FromGitter<xmonader> actually i'm not sure, because maybe they use the same package if the app not pinned against specific library?
20:15:07FromGitter<xmonader> @leorize do you use it as your daily driver?

22:52:08FromGitter<zacharycarter> there are multiple ways to do this
22:52:30PrimHelioszacharycarter: I don't think generics would work here as the return type wouldn't be known at compile time
22:52:54FromGitter<zacharycarter> oh only an int or bool - okay
22:53:24PrimHeliosnot necessarily, sorry. The return type would either be Future[T] or Future[bool]
22:53:25FromGitter<zacharycarter> actually I'm not sure a concept would work either
22:54:50FromGitter<alehander42> PrimHelios on what does it depend? are the args different types?
22:55:56PrimHeliosalehander42: I'm trying to make a generic version of asyncdispatch.withTimeout. The return type is either the type of the first argument, or `false`
22:58:16FromGitter<rayman22201> @PrimHelios why not just use the Option type? https://nim-lang.org/docs/options.html
