00:19:30FromGitter<genotrance> that's WIndows specific so that I could read giant files without running out of memory
00:20:19FromGitter<zacharycarter> hrm
00:20:34FromGitter<zacharycarter> probably not going to work on my macbook pro then :P
00:20:59FromGitter<genotrance> there's some bug with Nim file reading: https://github.com/nim-lang/Nim/issues/6031
00:21:43FromGitter<genotrance> i'm replacing that code with standard Nim since I am going to use nimSHA2 to do the file hashing, I no longer need to read the whole file in memory (I hope nimSHA2 isn't storing it all in memory and digests it right away)

07:44:51gokrHacking some Nim on Raspbian, anyone else using Nim on Rpi?
07:45:19gokrSeems to work perfectly fine, as I hoped of course, it's just Linux after all.
07:46:00gokrdom96: Perhaps choosenim should be extended to support it, I suspect it would just work out of the box.

07:52:37Tangergokr: Ooh, what are ya putting on the Rpi?
07:53:44gokrI am making a little server that will talk MQTT and REST (Jester) - and make calls out to other tools
07:54:17TangerCoolsies. How's Jester workin' for ya? I haven't gotten around to checking it out yet
07:54:53gokrJester is nice, I haven't done much with it yet - but I consider it to be the "standard" tool for such a job in Nim.
07:55:14gokrDominik has kinda proved that it's maintained by now ;)
07:56:00gokrFor MQTT I am using the wrapper of Paho C lib, unfortunately it doesn't do websockets AFAICT. It's also not listed in nimble, which it should be.
07:56:17*Ven`` joined #nim
07:56:19gokrThere is also a lower level "Nim only" MQTT implementation, but I suspect it may be less hardened ;)
07:56:41*vendethiel- quit (Ping timeout: 240 seconds)
07:57:33gokrThis job could just as easily be done in nodejs of course, but... well, Nim fits the bill.

08:45:33salewskiconnect(app, "activate", THISMODULE.activate) would be OK for me.
08:47:26salewskiAnd is there really a good change that the module name prefix will be unneeded when I rewrite the macro with AST API?
08:48:04salewskis/change/chance/
08:48:44Araqno sure but your string hacks are a time bomb, rewrite it already
08:50:05salewskiYes, but I am not sure how long rewriting will take for me. The macro is not that easy, so maybe it will take a week or longer for me.
08:51:15salewskiSo can we regard parseStmt() some sort of deprecated?

09:26:37skrylari made the same program with FLTK once and ported it over to wx. The wx version used 3x the memory and did nothing more.
09:26:47skrylarAlthough it did look native, whereas fltk doesn't :\
09:27:17skrylarWonder what extra things wx is doing

09:40:48kobi7hi guys, is there a debug for the vscode plugin? if yes, how to enable/use it?
09:40:54FromGitter<zacharycarter> no
09:40:59FromGitter<zacharycarter> use lldb / gdb
09:41:14FromGitter<zacharycarter> why does nimsuggest leak memory and how do we fix it so it does not?
09:41:18FromGitter<zacharycarter> because it's super annoying
09:41:24kobi7i never tried gdb :(
09:41:47gokrIIRC QtCreator worked nice for debugging, but any gdb based frontend should work.
09:41:47FromGitter<zacharycarter> kobi7: what os are you on?
09:41:56FromGitter<zacharycarter> QtCreator can work
09:42:03gokrIt did work nicely earlier.
09:42:17kobi7stepping in code lines, setting break points and looking at variables value is enough for a debug experience (for me)
09:42:26gokrAnd wasn't that hard to configure to get going - not sure if I blogged about it, or someone else did perhaps.
09:42:28kobi7I'm on linux
09:42:28FromGitter<zacharycarter> you can do all of that with gdb or lldb
09:42:33FromGitter<zacharycarter> okay so gdb then
09:42:40FromGitter<zacharycarter> try compiling your program like this
09:42:48gokrI ran it on Linux - the only thing you will have issues with is... deeper inspection of Nim stuff.
09:43:00gokrbreakpoints and all works nicely.
09:43:15FromGitter<zacharycarter> nim c --debuginfo --lineDir:on foo.nim
09:43:17gokrBut gdb isn't aware of seq, string etc, so... variable inspection is a bit "so so".
09:43:28kobi7gokr, is there something like a gui frontend?
09:43:43gokrkobi7: QtCreator is exactly that - it's a full blown C++ IDE.
09:43:59gokrKDE-whateveritscallde worked too IIRC.
09:44:20kobi7so you run the cpp binary in it?
09:44:38gokrOne can implement some gdp plugin in Python I think to get proper var inspection too - but I don't think anyone has done it yet.
09:44:44gokrYou debug it, yeah.
09:44:48gokrIt works great.
09:44:55gokrBut was a while since I did it.
09:45:14kobi7and you got correct nim-code lines?
09:45:23kobi7line numbers
09:45:27gokrLook at this: https://forum.nim-lang.org/t/1229
09:46:09gokrAh, its in QtCreator proper now - right: https://codereview.qt-project.org/#/c/123629
09:46:59kobi7yay!
09:47:09gokrNim support was added officially in 4.1.0: http://blog.qt.io/blog/2016/08/25/qt-creator-4-1-0-released/
09:47:22gokrBut... filcuc is not around here I see. It's his work.
09:47:51gokrNow that you bring it up... I will try it next week :)
09:48:07FromGitter<zacharycarter> my recommendation is use gdb and learn how to debug with the commandl ine
09:48:19FromGitter<zacharycarter> you may not always have qt creator at your disposal but you'll most likely have gdb | lldb
09:48:28FromGitter<zacharycarter> then use something like QtCreator if you must have a visual debugger
09:48:32gokrSure, agreed.
09:48:37FromGitter<zacharycarter> I get along fine without one, and QtCreator / the QtFramework is a huge install
09:48:38FromGitter<zacharycarter> fyi
09:48:39gokrBut... it's so painful :)
09:48:40skrylarzacharycarter: is it stuff getting stored in caches?
09:49:05FromGitter<zacharycarter> skrylar maybe - I haven't dug through the nimsuggest source I guess i'll do that now
09:49:31skrylarnods
09:49:42skrylari would suspect caches before leaks. not that gcs make leaks impossible but
09:50:08skrylarone complaint i always have with gc apps is they don't act like other programs might exist, so they just kinda all use memory and hope the OS magically solves it
09:50:24FromGitter<zacharycarter> right
09:50:41*solitudesf quit (Ping timeout: 240 seconds)
09:50:48FromGitter<zacharycarter> well hopefully araq finishes that crazy algorithm implementation he was going to implement and allows the gc to be turned off
09:50:55FromGitter<zacharycarter> I can't remember wtf it was called
09:51:00skrylararc?
09:51:09Araqmemory regions?
09:51:41FromGitter<zacharycarter> no
09:51:46skrylari don't have issues with the gc tho. i turn it off at the start and just have the incremental run between frames
09:52:04FromGitter<zacharycarter> I'll try to find the document again
09:52:19FromGitter<zacharycarter> Araq you said it was just an experimental thing you were looking into
09:52:32skrylarhe also said he wanted r-trees for something :p
09:52:36FromGitter<zacharycarter> and you linked to a paper by someone about something - I know that's super helpful /
09:53:00*mal`` quit (Quit: Leaving)
09:53:05FromGitter<zacharycarter> basically what are the plans for going GCless with Nim? or are there any?
09:53:33skrylari always thought turning the gc off was more about microcode than a general goal
09:53:46*gokr quit (Remote host closed the connection)
09:54:17FromGitter<zacharycarter> I don't know what the polls showed - I think I remember Araq saying it sounded like most people were fine with the current GC options - I for one would like the ability to forego GC all together
09:54:34FromGitter<zacharycarter> and I think the other options mentioned in the poll were like ARC, and then maybe some other options too
09:54:57skrylari don't believe gcs are inherently evil
09:55:04skrylarthey just need OS support >:|
09:55:14Araqwell...
09:55:22FromGitter<zacharycarter> :popcorn:
09:56:08skrylari saw some whitepaper come across that was suggesting an ocaml GC was faster than boost pointers. and read some old lisp things that were talking about being more aggressive with code gen when they didn't have to maintain the whole deref logic
09:56:37skrylarand most complaints about a GC are that they are acting randomly instead of on predictable cue
09:57:20skrylarlike arc is continuously having to stop and do atomic writes
09:57:40*mal`` joined #nim
09:58:00skrylarbut i'm not a GC god so, dunno.
09:58:06AraqI still want memory regions but to make them safe the overhead is comparable to a good GC
09:58:17FromGitter<zacharycarter> wow
09:58:46Araqand they are never a "program and forget" solution
09:58:53FromGitter<zacharycarter> didn't realize it was that much work
09:58:55FromGitter<zacharycarter> right
09:59:12Araqif we go for unsafe regions things are smooth though :-)
09:59:44FromGitter<zacharycarter> so unsafe memory regions are already available and usable right?
09:59:54Araqkind of.
10:00:02Araqbootstrapping works
10:00:09Araqtakes 2GB
10:00:46FromGitter<zacharycarter> dayum
10:02:20FromGitter<zacharycarter> You know what's super annoying? I'm trying to compile zengine for emscripten and remove all references to OS packages / shit that emscripten can't handle. But I just get errors like - ⏎ ⏎ ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=59c4dfac7b7d98d30d24e1a8]
10:03:31FromGitter<zacharycarter> can't tell where the bad import is
10:03:45skrylarspeaking of zengine
10:04:16skrylari am currently on a mind trip trying to understand sparse virtual textures and these weird adaptively sampled distance fields
10:04:28skrylarthey seem like they would go together in some horrifying-yet-awesome way
10:05:04FromGitter<zacharycarter> had never heard of sparse virtual textures before

10:05:42FromGitter<zacharycarter> yeah was just reading that page
10:05:57skrylarthere's also Mischief which allegedly uses these weird distance field octrees
10:06:03skrylartheir gimmick is you can zoom infinitely and sketch
10:06:21skrylari guess they're recording strokes as vector lines and then putting those in some weird old data format
10:07:23skrylari remember back in like 2000 having dreams of nurbs/bezier models because that was when people were doing these model updates for deus ex. and it was like you know if anyone invested R&D in those you could just set your game to potato mode or something
10:07:35skrylari think they're kinda going that way with substance now

10:08:49FromGitter<zacharycarter> yup!
10:08:53skrylarit was an octree with cube deformation edges and could subdivide. that seem very similar to what ADFs are

10:17:38FromGitter<Yardanico> I see araq is doing some things with strings and codegen :P
10:24:34skrylarzacharycarter: now here's a pipedream for you. if there was a way for the UVs to survive conversion to ADFs, and i donno if there is or not, you could *theoretically* just cram any random scene in one
10:24:42skrylarwould still be a static scene, but hey.
10:24:59FromGitter<zacharycarter> would be cool
10:25:11skrylarwell in the paper they talk about you can simplify geometry by just not recursing
10:25:47skrylarit might still result in some weird geometry tho, as LOD algos always do
10:25:57kobi7hmm, I stumbled upon: https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools
10:28:08FromGitter<Yardanico> yeah you can use that
10:28:25FromGitter<Yardanico> also I highly recommend this - https://github.com/cooldome/Nim-gdb
10:29:18FromGitter<zacharycarter> ugh still not sure how to diagnose these emscripten compilation errors
10:31:02FromGitter<Yardanico> take a look at this
10:31:03FromGitter<Yardanico> https://github.com/Jipok/Nim-SDL2-and-Emscripten/blob/master/nim.cfg
10:31:16FromGitter<Yardanico> you should use "emcc" compiler btw
10:32:09FromGitter<zacharycarter> I am
10:32:50FromGitter<Yardanico> well try adding "-Iemscripten" to passC and passL
10:33:06FromGitter<zacharycarter> I don't think that's my issue
10:33:14FromGitter<zacharycarter> something in my code is importing modules emscripten doesn't support I imagine
10:33:21FromGitter<Yardanico> no
10:33:24FromGitter<Yardanico> stdbool is fine
10:33:26FromGitter<Yardanico> it should work
10:33:39kobi7Is there something like a makefile for nim? IOW, some preferred nim way to build?
10:33:54FromGitter<zacharycarter> oh weird okay
10:34:23FromGitter<Yardanico> kobi7: yourproject.nim.cfg or yourproject.nims
10:34:29FromGitter<zacharycarter> GOOD CALL @Yardanico
10:34:33FromGitter<Yardanico> ?
10:34:35FromGitter<zacharycarter> it wasn't picking up my nim.cfg
10:34:39FromGitter<zacharycarter> thank you!
10:35:18euantorkobi7: Usually just use Nimble and do `nimble build`
10:35:40FromGitter<Yardanico> yeah, nimble should be sufficient
10:35:55euantoror `nimble install` for a release build
10:36:01FromGitter<Yardanico> but sometimes you need to define some things
10:36:02FromGitter<Yardanico> like -d:ssl
10:36:06FromGitter<Yardanico> does nimble file allow that?
10:36:43euantoryou can put that in a `nim.cfg`, not sure about a `.nimble`
10:37:06FromGitter<Yardanico> but yeah, kobi7, .nimble file + nim.cfg is higher-level than makefile :)
10:37:08FromGitter<Yardanico> so easier to use
10:37:13kobi7Thanks, Yardanico
10:37:36kobi7how can I choose the output binary filename?
10:37:48euantoruse the `-o` option
10:38:00euantoror set the `bin` key in the `.nimble` file
10:38:14kobi7thanks, it doesn't show up in `nim --help`

12:24:21skrylarits better than libui at least, lol
12:24:57skrylarlibui could have been pretty good actually, it just lacked some really basic stuff
12:25:14*Yardanico joined #nim
12:26:03FromGitter<zacharycarter> skrylar: maybe consider contributing to NiGUI ?
12:28:14skrylari just googled that
12:28:37skrylari could, although that puts me back in the same pit i was trying to avoid regarding wrapping gtk3's bajillion headers
12:28:58Yardanicowell this is not entirely a wrapper
12:29:05Yardanicoit wraps only low-level stuff of winapi and gtk3
12:29:17Yardanicoand does other stuff by itself
12:29:20Yardanicoe.g. layouts
12:29:29skrylari keep meaning to do miglayout in nim
12:29:35skrylari almost did it in Go once
12:30:00skrylarhttp://www.migcalendar.com/miglayout/cheatsheet.html
12:30:53skrylarbetween mig and hirise you don't need any other layout stuff
12:31:06FromGitter<zacharycarter> I think the plan is to eventually ditch gtk3
12:31:08FromGitter<zacharycarter> for NiGUI
12:31:09Yardanicoomg this website has so small font size :P
12:31:11FromGitter<zacharycarter> and go native
12:31:18Yardanicowhat do you mean by "native" ? :)
12:31:27skrylargtk is native to half of linux
12:31:36Yardanicoand "winapi" is native to all windows
12:31:49FromGitter<zacharycarter> like for osx I don't think he wants to use gtk
12:32:01skrylarthey drink cocoa over there.
12:32:07FromGitter<zacharycarter> aye
12:32:13skrylari miss being a mac nerd.
12:33:02skrylarunfortunately the imac on my desk now is only good for office work. it won't run Substance or any shader 3 stuff.
12:33:27Yardanicoinstall windows on it ? :P
12:33:32FromGitter<zacharycarter> heh
12:33:37Yardanicoor it has an old GPU?
12:33:40skrylarold gpu
12:33:48skrylarthe box is 9 years old
12:33:50Yardanicooh
12:34:45skrylarhirise is neat but i still don't grok the math.
12:35:01skrylarthey're basically modeling constraints in a matrix and doing some thing on it to solve a linear system
12:35:27*Yardanico quit (Remote host closed the connection)
12:35:45skrylarbut i used somethintg like it in freepascal/lazarus, it's quite nice. you just like, have your text labels auto-size (DPI scaling, etc) and then the whole UI is specified relative to everything
12:35:54skrylar"this is 3px to the right of that label"
12:36:25*gmpreussner quit (Quit: kthxbye)
12:36:58skrylarAnything that isn't one of those two, basically, is Wrong(tm). Not because I hate fun, but absolute positioning doesn't DPI/retina scale
12:37:16skrylarand those weird box sizers require a lot of BS
12:39:17*gmpreussner joined #nim
12:40:13FromGitter<zacharycarter> interesting - it looks like I can use the OpenGL bindings with emscripten
12:40:17FromGitter<zacharycarter> I'm just limited to a 2.0 context
12:42:31skrylarreally? i thought webgl was 3
12:42:35skrylaralthough egl is 2 so i guess so
12:42:40skrylarwebgl is basically egl
12:42:44FromGitter<zacharycarter> yeah

12:43:16skrylar"i will not perform math intensive operations in a scripting language and shove it on to the gpu slowly"
12:43:16FromGitter<zacharycarter> basically if I don't do - glSetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, VERISON_NUMBER)
12:43:28FromGitter<zacharycarter> it creates a 2.0 context automatically
12:43:40skrylarit creates whatever context the OS decides you get iirc
12:43:47skrylarwhich on a mac is going to be 3.0
12:44:24FromGitter<zacharycarter> it def doesn't work with a 3.0 context
12:45:37skrylarand once again krita has decided to be an unstable piece of crap
12:45:40skrylaroh well ._.
12:46:01*claudiuinberlin quit (Client Quit)
12:51:35FromGitter<krux02> isn't that the kde paint clone?
12:51:56FromGitter<krux02> how about grafx2?
12:58:08skrylarit used to be a gimp clone, now its a decently respected paint program
12:58:18skrylarexcept somehow i always get a broken version on linux
12:58:30skrylarit worked fine but now it segfaults when you try to save files :v
12:59:03FromGitter<krux02> hmm
12:59:11FromGitter<krux02> I mixed up krita and pinta
12:59:16Vladarwhat version? Krita works fine for me for a while
12:59:17FromGitter<krux02> pinta is a paint clone
12:59:47skrylarVladar, all of them. i tried a git version, there's some crash in libkritastore
12:59:56skrylari'll see if a reboot fixes it later, done with art for now
13:00:07FromGitter<krux02> I personally think gimp is unnecessarily complicated with too much loading time, I have no opinion about krita, but mypaint is nice and simple
13:00:23FromGitter<krux02> and I like grafx2, but I am no artist
13:00:43FromGitter<krux02> so don't put too much weight in my opinion :P
13:01:05Vladaras for _painting_ Krita is the leader if we are talking linux-wise,
13:01:18skrylarmypaint is what i used because it has always worked
13:01:39skrylari had a friend who was trying to get in to krita and it kept dying at random moments
13:01:59Vladarmypaint is not bad, but dat krita's brush engine…
13:02:10FromGitter<krux02> is there a way to translate an identifier into a string within a template?
13:02:11skrylarkrita is using mypaints engine lol
13:02:13Araqthat is a nice one: https://github.com/nim-lang/Nim/issues/6416
13:02:22Araqkrux02: astToStr
13:02:31FromGitter<krux02> thanks
13:02:35Vladarskrylar, do you have a source for this?
13:02:44*ShalokShalom_ is now known as ShalokShalom
13:02:51Araqmaybe we should get rid of exceptions :P
13:03:35skrylarVladar, https://github.com/KDE/krita/search?utf8=✓&q=mypaint&type= well, they used to.
13:03:51skrylarI remember in earlier versions you could select 'mypaint brush' as a brush engine when editin them
13:05:00FromGitter<krux02> I don't really use exceptions, so I would not miss them
13:05:05FromGitter<zacharycarter> +1
13:05:20skrylardo you want every call to be if geterr hell
13:05:31FromGitter<krux02> nope
13:05:54FromGitter<krux02> I think a result type for functions that might fails does handle it pretty well
13:06:07FromGitter<krux02> Result[string]
13:06:23skrylargonna bog the cpu down in cmp's doing that :\
13:06:29FromGitter<krux02> result would either be a string, or the exception as a value
13:06:52FromGitter<krux02> if you try to get the value when it actually is an exception, then it would print the stack trace and exit

16:06:09FromGitter<Yardanico> you can disable optimizations with pragmas, no?
16:08:16FromGitter<mratsim> when I said optimisation it was replacing a + b by a pointer to host memory or things like that. cudanim found a clever way to avoid that but to be honest i couldn’t understand all of what was going on in their code

16:52:55FromGitter<Jipok> Hi. I recently found this project. It can serve as good gui for small utilities ⏎ https://github.com/DeXP/nuklear_cross
16:59:34FromGitter<Yardanico> yeah, I saw post on habrahabr
16:59:54FromGitter<Yardanico> but btw, imgui does the same thing as nuklear+
17:00:15FromGitter<Yardanico> well there are predefined backends for imgui
17:01:48FromGitter<Yardanico> @Jipok make a nim wrapper for it :)
17:03:12FromGitter<Yardanico> there's already a nuklear wrapper
17:03:40FromGitter<zacharycarter> ehhhh not a fan of nuklear_cross
17:03:50FromGitter<zacharycarter> and yes nuklear bindings exist already
17:03:58*dhalinar joined #nim
17:04:10FromGitter<Yardanico> @zacharycarter why not?
17:04:37FromGitter<zacharycarter> because it's just various backends for nuklear which are easy enough to write yourself
17:04:47FromGitter<zacharycarter> and besides which one backend doesn't necessarily suit every use case for nuklear
17:05:04FromGitter<zacharycarter> the point of nuklear is it is supposed to be api-agnostic
17:05:33FromGitter<Yardanico> well but if you want to write a simple gui utility, you don't want to waste your time writing a nuklear backend :)
17:06:20*BitPuffin|osx joined #nim
17:06:24FromGitter<zacharycarter> you also don't necessarily want as your only backend optoins

17:08:42FromGitter<Yardanico> yeah
17:08:59FromGitter<Yardanico> and they cover all major platforms
17:09:21FromGitter<Yardanico> SDL, GLFW - multiplatform, xlib - Linux, gdiplus - windows
17:13:54FromGitter<zacharycarter> yeah you're right - I still wouldn't write bindings to them though the backends are trivial enough that you could and should just implement them in Nim

17:16:50FromGitter<zacharycarter> <3 it
17:17:08FromGitter<Yardanico> nice
17:17:40FromGitter<Yardanico> dom96: is there any progress on nim community survey analysis ? :)
17:18:26TjYocoI usually opt-out of these things but I don't see a reason not to have this feature
17:18:45dom96Yardanico: No, I'm mostly putting it off
17:18:49dom96It's a boring job :)
17:19:53dom96glad you guys like this though :)
17:21:40FromGitter<Yardanico> well if I use google all the time, what could be worse ? :)

17:30:36FromGitter<Yardanico> I'm about survey
17:31:21shodan45nim needs some endorsements, like on https://myrlang.org/release-notes/
17:32:04FromGitter<Yardanico> endorsements?
17:33:43FromGitter<Yardanico> website looks like something from 2000's :)
17:34:10shodan45Yes. Isn't it awesome? ;)
17:34:30FromGitter<Yardanico> well they're not for my personal preference :)
17:35:44shodan45also.... this "Gitter" thing breaks tab completing their nicks >_>
17:35:56FromGitter<Yardanico> I like this: "Libregex handles regexes. It implements a simple but powerful regex syntax, and has working Unicode support."
17:36:03FromGitter<Yardanico> working unicode support :)
17:37:01shodan45ugh. just now finding out what gitter is. *why*.
17:37:21FromGitter<Yardanico> Gitter is a chat with rooms, mostly for github projects
17:37:36FromGitter<Yardanico> "Gitter is an open source instant messaging and chat room system for developers and users of GitHub repositories."
17:37:42FromGitter<Yardanico> you can log-in via twitter or github
17:38:08shodan45I see that. And I'm still lost at to why it's better than IRC.
17:38:40FromGitter<Yardanico> you can embed images!
17:38:48FromGitter<Yardanico> and it's easier-to-use really
17:38:55FromGitter<Yardanico> it has specific github support
17:39:05shodan45IRC is hard?
17:39:23FromGitter<Yardanico> I don't mean "hard"
17:39:45FromGitter<Yardanico> example about github support : https://github.com/nim-lang/Nim/issues/6412
17:39:55FromGitter<Yardanico> this will be displayed as "nim-lang/Nim#6412" on gitter

17:40:02*mahmudov joined #nim
17:40:12shodan45I use quassel, which is relatively complicated to setup. And I managed.
17:40:45FromGitter<Yardanico> also you can use gitter in the browser. yeah, I know about different web clouds, but with gitter you don't need to connect again after leaving the website
17:41:10FromGitter<Yardanico> also gitter has full markdown support :)
17:41:17shodan45that sounds a bit like what quassel does
17:41:23shodan45not the markdown part
17:41:28FromGitter<Yardanico> also "Integrations for Trello, Jenkins, Travis CI, Heroku, Sentry, BitBucket, HuBoard, Logentries, Pagerduty & Sprintly are available."
17:42:16shodan45I wouldn't mind it if it didn't screw with how IRC already works
17:42:23shodan45but it does.
17:42:26FromGitter<Yardanico> how ? :)
17:42:32shodan45o_O
17:42:56FromGitter<Yardanico> I use IRC from linux, and gitter from windows
17:43:01FromGitter<Yardanico> And I don't see any issues from both sides
17:43:29shodan45you aren't logged in to freenode as your own user
17:43:38FromGitter<Yardanico> I'm from windows right now
17:43:40shodan45"FromGitter"
17:43:47FromGitter<Yardanico> yes
17:44:09FromGitter<Yardanico> since this bridge is made by gitter, not by freenode
17:44:20shodan45anyway, I gtg.
17:44:23FromGitter<Yardanico> so they can't use your logins
17:44:34*shodan45 twitches

17:55:09dom96and I don't use it anymore
17:55:11FromGitter<mratsim> By the way @dom96, you could put the result of the Nim survey as open dataset on Kaggle: https://www.kaggle.com/datasets. I have lots of friends there that can give you excellent visualization

18:03:02FromGitter<Yardanico> @mratsim maybe #nim, not #Nim ?
18:03:09FromGitter<mratsim> oooohhh

18:07:01FromGitter<Yardanico> they're too small

18:08:50FromGitter<mratsim> one of the other interesting language with a meta programming focus and easy C-C++ FFI I saw was terralang: http://terralang.org/
18:10:02FromGitter<Yardanico> yeah, it's highly integrated with lua
18:10:38FromGitter<Yardanico> so it doesn't have it's own VM
18:10:41FromGitter<Yardanico> it just uses Lua :)

18:26:20FromGitter<edubart> lua is not a bad lang, its simple, compact, you can almost embed everywhere, do easy C bindings
18:26:53Araqit's also error prone as fuck, every typo is a bug
18:26:56FromGitter<edubart> and terralang make its more powerful, although I doesn't seems active
18:27:09*jsgrant quit (Quit: jsgrant)
18:27:12Araqbut when you do live coding maybe it doesn't matter
18:27:30*jsgrant joined #nim
18:28:44FromGitter<edubart> this depends on the person, nim is every error prone for me, but mostly because I am not familiar
18:30:44Araqso ... your Nim typos produce bugs?
18:30:56Araqnever heard that before from anybody.
18:32:23FromGitter<Yardanico> well yeah, it's mostly the issue with interpreted languages
18:32:30FromGitter<Yardanico> they don't usually bother checking source code a lot
18:32:43FromGitter<Yardanico> maybe just check the syntax, and run the code
18:34:06FromGitter<Yardanico> so with Nim, if you have come type errors: try to compile, fail, fix, try again
18:34:25FromGitter<Yardanico> in python: run it and wait for needed code to execute, fail, fix, try again
18:34:36FromGitter<Yardanico> well it's actually true for most modern compiled languages
18:37:08adeohluwa@ araq is so blunt it always sound like he's joking :D
18:38:39adeohluwa@edubart I'll disagree & I'm also not super familiar with nim but I'm able to run just by glancing @ docs & Rosetta code example quick check

19:00:27FromGitter<zacharycarter> anyone have any ideas why my call to glClearColor wouldn't work w/ emscripten?
19:00:45FromGitter<zacharycarter> is it because I didn't call loadextensions? which I can't call anyway w/ emscripten
19:01:39FromGitter<mratsim> When I say a lot, the goal is to saturate all your GPU memory so, 8GB~12GB every 10 seconds or so

19:20:50dom96yep
19:20:58dom96Nim should be there too
19:21:21FromGitter<Yardanico> sadly we don't have nightly builds :(
19:22:01FromGitter<Yardanico> ah
19:22:06FromGitter<Yardanico> it seems we can compile nim too
19:22:43adeohluwaYardanico: yes... you are bn really useful
19:25:02FromGitter<Yardanico> hmm I don't really think we can compile nim every time
19:25:13FromGitter<Yardanico> probably it would only support stable builds (from ubuntu launchpad)

19:28:03FromGitter<Yardanico> federico3: these scripts are different
19:28:04federico3however CircleCI support docker images...
19:28:09dom96You can cache the builds, like I do for choosenim.

19:28:33FromGitter<Yardanico> can you do caching with travis language script?
19:29:33dom96No idea
19:30:01dom96You can use docker though https://docs.travis-ci.com/user/docker/

19:30:40FromGitter<Yardanico> @Bennyelg you can only do that if string is known at compile-time

19:30:54FromGitter<Bennyelg> it is,
19:31:08FromGitter<Bennyelg> I need use the "when"
19:31:08FromGitter<Bennyelg> ?
19:31:10FromGitter<Yardanico> then change "string" to "static[string]" in procedure arguments
19:31:13FromGitter<Yardanico> and use when
19:31:21FromGitter<Bennyelg> i thought to use case

19:31:38FromGitter<Yardanico> and declare return type like this: "int | string"

21:06:00FromGitter<mratsim> I can’t do when compile(proc boo … multiline …), and just declaring the proc will stop the whole test suite (which is ugly but well, if it’s not possible to have the test suite continue, I’ll take it)
21:06:34FromGitter<mratsim> I didn’t try on Windows but there is Appveyor CI so it should work. I do have to configure CI for cuda builds on Windows and Linux

21:58:17dom96Then second thing would be changing the casing of your types
21:58:28dom96The convention is to start with UpperCase letters for types.
21:59:36obadzis there an easy way to turn a string in a array[N, char] ? cstring() gives a type error. Do I need to loop?
22:01:33Serenitori'll see to it to set up a test case. though i'd like to have be type's casing consistent with the default types (int, float, ...). i use uppercase for constants and enums values

22:14:40obadzfirst time I'm asked for the code mess when I've boiled it down to the 1-line repro :)
22:14:51obadzI'm trying to call ioctl()
22:15:16obadzit takes an ifreq struct that has tons of submembers with unions, arrays, etc.
22:15:30obadzI've used c2nim and fiddles with the result until it compiled
22:16:14obadzbut now I struggle to instantiate values of this type (I'm a nim newb). I've figured out how to deal with unions but not sure how to deal with arrays.
22:16:16FromGitter<zacharycarter> all I really need to see is the proc signature you've produced for binding and how you're trying to call it
22:17:03FromGitter<zacharycarter> maybe you need an unchecked array?
22:17:05FromGitter<zacharycarter> not sure
22:17:19obadzI'm calling Posix.ioctl, but passing stuff in the untyped varargs
22:17:28obadzso I don't think the signature will help
22:18:02obadzhttps://gist.github.com/obadz/f4d8a1ed3974c1330bc964835148ad24 ⇐ this is the ifreq type
22:18:18obadzifrn_name for instance is an array[IFNAMSIZ, char]
22:18:27obadzhow should I instantiate that?
22:22:36FromGitter<zacharycarter> it's weird ifr_ifrn_union is a union
22:22:47FromGitter<zacharycarter> because it's apparently not unioning anything?
22:22:48FromGitter<zacharycarter> but uh
22:23:03obadzit's unioning all the members below?
22:23:08obadzoh
22:23:11obadzsorry yes
22:23:15obadzI named that one badly
22:23:36obadzlet me check why c2nim made it a union
22:25:29obadzhttps://github.com/torvalds/linux/blob/master/include/uapi/linux/if.h#L230-L252 ⇐ I guess c2nim is doing what it's told…
22:26:24obadzanyway the union isn't the issue here. I don't understand why this snippet corrupts memory: let s = "blah"; let x = cast[array[10, char]](s); echo "Array: ", $x
22:26:44FromGitter<zacharycarter> we probably need Araq for this convo, or someone with more Nim knowledge than myself
22:27:11obadzk, thanks for trying.
22:27:46FromGitter<zacharycarter> sure thing, sorry I can't be of more use
22:28:52obadzlol so if I do let x = cast[array[10, char]]("hi".cstring)
22:29:03obadzx[0] == "R" and x[1] == "C"
22:29:09obadzI assume that's for refcount? ;-)
