00:18:07FromGitter<zacharycarter> how do you do eager matching on libnames for dll imports
00:18:16FromGitter<zacharycarter> I want to do something like - const LibName = "Assimp32|64.dll"
00:19:48skrylarhrmm
00:19:53skrylarmacros don't like you redefining []=
00:20:56skrylaroh nvm
00:22:54skrylarzacharycarter did that set of easing routines ever turn out to be useful
00:23:00skrylari never made the tweening module they were for :\
00:30:55*skrylar quit (Remote host closed the connection)
00:33:15FromGitter<zacharycarter> I haven't used them yet skrylar but I imagine they will be once I start to need them
00:33:34FromGitter<zacharycarter> there is zero easing logic in zengine atm so as soon as I need some I imagine it will become useful
00:34:02FromGitter<zacharycarter> sprite animations are about to be a thing so I imagine we could find some use there

01:00:03FromGitter<mratsim> Both are target at programmers that want to start with deep learning/neural net. The first one will give you high level tools, understanding while the second one is on low level implementation

10:23:32*yglukhov joined #nim

10:34:23Yardanicobut you cna read his comments
10:35:06Yardanicobtw his twitter - https://twitter.com/Sin_tel
10:35:14federico3"The tiles are 8x12 but they are drawn on an 8x8 grid. Make sure everything is drawn back to front, so the extra 4 pixel can overlap"

10:35:50Yardanicoalso he applies some effects
10:35:54Yardanicobloom, scanlines
10:36:04Yardanicoin ascii game lol
10:36:16Yardanicowait, is this game run in an terminal?
10:36:21FromGitter<zacharycarter> no way
10:36:28Yardanicoor it's ascii-like, but in normal window?
10:36:33FromGitter<zacharycarter> yaeh
10:36:33federico3and coloring... but even the explosions are done with the font alone

10:42:38federico3zacharycarter: everything, not only the walls - and they are not "images" but font characters
10:42:48FromGitter<zacharycarter> are they actually characters?

11:15:10FromGitter<mratsim> so @zacharycarter when is Nim wrapper for Love2D (the engine he uses) ?
11:16:27Yardanicoit uses SDL
11:16:40YardanicoIIRC
11:16:43FromGitter<krux02> @mratsim shameless self advertisement: https://github.com/krux02/opengl-sandbox
11:16:50FromGitter<krux02> not love2d
11:17:15FromGitter<krux02> great macro library to easily use opengl functionality efficiently
11:17:40FromGitter<zacharycarter> @mratsim heh I have no idea
11:17:55FromGitter<zacharycarter> I imagine it's possible since it's written in Lua
11:17:56FromGitter<krux02> It runs on all platforms with a half decent OpenGL implementation (excludes MacOS)
11:17:57FromGitter<zacharycarter> and things like
11:18:04Yardanicowell it would be not efficient
11:18:08FromGitter<zacharycarter> https://github.com/jangko/nimLUA
11:18:12FromGitter<zacharycarter> no probably not
11:18:39FromGitter<ephja> IIRC a lot of it is written in C++
11:18:39FromGitter<zacharycarter> my advice is to pick a Nim project, like zengine or opengl sandbox or nimgame etc and contribute!
11:18:53FromGitter<mratsim> Yep I saw it before @krux02, looks really nice. Maybe someday I will try learning game dev.
11:18:58FromGitter<zacharycarter> and if you don't want to do that, use godot nim
11:19:22FromGitter<krux02> did you see the video?
11:20:26FromGitter<mratsim> where is it? I can’t find a link
11:20:35*loc8 joined #nim
11:20:46FromGitter<krux02> https://www.youtube.com/watch?v=JO0iqGDgFqA
11:20:55loc8Are generic types handled at compile time?
11:20:58FromGitter<mratsim> ah “Demo” at the top
11:20:58FromGitter<krux02> it doesn't cover everything
11:21:03FromGitter<krux02> loc8: yes
11:21:09FromGitter<krux02> like c++ templates
11:21:40FromGitter<mratsim> You should put 10 seconds of it as an animated GIF directly at the beginning of the readme
11:21:54loc8I have a `Type[T] = object of RootObj` and I extend it with `String* = ref object of Type[string]`
11:22:10loc8on the `newString` proc, I create the new object normally
11:22:34loc8It receives a `T` and stores it at the property `value: T` of `type`
11:22:46loc8It works normally with regular variables, but the compiler complains if it's a const
11:22:59Yardanicocan you give an example code snippet?
11:23:02loc8Yup
11:23:07Yardanicoon gist for example
11:24:24Yardanicowell maybe you're trying to create a "ref" type as a const
11:24:32Yardanicooh wait this would work
11:24:53Yardanicoah, no
11:25:33FromGitter<mratsim> btw I remember a recommendation/suggestion to use `object {.inheritable.}` instead of `object of RootObj`, is there any practical difference?
11:26:19FromGitter<mratsim> well more like `customType {.inheritable.} = object` I suppose
11:26:20FromGitter<krux02> @mratsim I guess that RootObj increases the size of the object
11:26:36loc8Yardanico, https://gist.github.com/10c8/42d3e849251756721666972b014b567a
11:26:45Yardanicoyeah
11:26:47FromGitter<krux02> but I am not sure here
11:26:51loc8Can't create const refs?
11:26:51Yardanicoyou can't make ref types as const
11:26:54Yardanicoloc8, you can't
11:27:01Yardanicobecause they're references
11:27:17Yardanicoah wait
11:27:31FromGitter<ephja> I dunno why RootObj would take up more space
11:27:44loc8It still gives me an error even when it's an `object of Type[string]`, not ref
11:27:53FromGitter<krux02> loc8: my hint, if you try to avoid ref types, you will realize you won't need them
11:27:56Yardanicowell yeah
11:28:01Yardanicothere's some different error
11:28:27loc8Same one, `cannot create null element for: [T]`
11:28:37YardanicoI mean it's not related to ref
11:28:41loc8Oh got it
11:29:59FromGitter<mratsim> @krux02 The part around 11:16 is worth a GIF in my opinion: https://youtu.be/JO0iqGDgFqA?t=676
11:30:13loc8Any idea what it's related to then>
11:30:19loc8?
11:30:44Yardanicowell it's already reported
11:30:46Yardanicoon github
11:30:46Yardanicohttps://github.com/nim-lang/Nim/issues/6014
11:31:14loc8So it's a bug
11:31:16Yardanicoyes
11:31:18FromGitter<krux02> @mratsim you mean the postprocessed cube?
11:31:28FromGitter<mratsim> yeah
11:31:57FromGitter<krux02> I will think about it. And yes it shows some non trivial to implement processing steps at the same time
11:32:07FromGitter<krux02> but still it is very simple
11:32:44FromGitter<mratsim> Showing that only a few lines of code allow that is good, and OpenGL is graphics, so talk with graphics ;)
11:33:25FromGitter<krux02> well I am a bit tied to opengl I never really learned another rendering API
11:33:42FromGitter<krux02> there isn't that much choise on Linux
11:33:49Yardanicoyeah
11:34:03Yardanicoand opengl is most cross-platform and supported everywhere
11:34:08FromGitter<krux02> there is Vulkan, but that is new and I am not exited to be the first who seens all the bugs
11:34:40FromGitter<mratsim> Why are you using Nim then ;)
11:34:43FromGitter<krux02> Yardanico: well you would guess, but opengl support on MacOS is pretty weak
11:35:18Yardanicolol, I didn't knew
11:35:28Yardanicodo they have their own API?

11:37:40FromGitter<krux02> yes they have their own API now called metal and since then OpenGL hasn't been developed further
11:37:44FromGitter<krux02> on Apple
11:37:57FromGitter<krux02> the newest version Apple supports is now 7 years old
11:38:08Yardanicowow
11:38:46Yardanicook, but I can't really say anything about that because I don't own any of the Apple products :)

11:39:22Yardanicoit works without any issues, but it's not for me

11:40:08FromGitter<krux02> that's my experience with apple, and back then my father decided Apple is too expensive
11:40:48Yardanicowell it is quite expensive in Russia too comparing it to the average salaries :P
11:41:02FromGitter<krux02> I found an old catalog with apple products, the floppy drive alone was 600$

11:45:24FromGitter<zacharycarter> yeah I like my macbook pro as well

11:45:36FromGitter<zacharycarter> :shrug:
11:46:02FromGitter<krux02> well I don't have the latest opengl extensions as well
11:46:14FromGitter<krux02> but at least within the last 7 years there has been development
11:46:21FromGitter<krux02> there was momentum
11:46:29FromGitter<krux02> on Apple it is just no momentum at all
11:47:01FromGitter<krux02> I run on MESA software renderer, and that one has better extension support than APPLE drivers
11:47:37FromGitter<krux02> I am talking about mesa software rendering, and that one was never something you wanted to use
11:47:47Yardanicoyou don't have a GPU?
11:49:36FromGitter<krux02> well I have a used laptop that is too many years old and was never good at graphics with intel chip
11:49:47FromGitter<krux02> my later opengl Version is 2.1
11:50:13FromGitter<krux02> I don't want to use that version, I wanted at least to use a core version so I switched to software opengl
11:50:44FromGitter<krux02> it has the nice sideeffect that all examples in the examples folder run smoothly on software rendering

16:21:32FromGitter<BigEpsilon> Hi, what is the correct way to emit a warning during compilation phase ?
16:22:35ipjkMaybe, static: echo "[warning] this shouldn't happen"?
16:23:14FromGitter<BigEpsilon> I want to emit a warning when a circular dependency is detected between other things than types or consts when using the reorder pragma
16:24:40FromGitter<BigEpsilon> but this wont get the color like compiler warnings and hint right ?
16:25:33Yardanicoipjk, no
16:25:51Yardanicouse this pragma
16:25:56Yardanico{.warning: "sample text"}
16:26:04Yardanico{.warning: "sample text".}
16:26:42ipjkOh, cheers for the heads up
16:26:56FromGitter<BigEpsilon> thanks for you both !

16:27:36*Elronnd joined #nim
16:28:04FromGitter<BigEpsilon> in fact it is not realy a compile time warning that I need sry
16:28:27FromGitter<BigEpsilon> it is during the processing of a pragma
16:28:50FromGitter<BigEpsilon> in the compiler
16:29:08Yardanicoah
16:29:11FromGitter<BigEpsilon> so it's a runtime warning in the compiler
16:29:13Yardanicothen search compiler source ? :)
16:29:28FromGitter<BigEpsilon> yes 'ill search for that warning pragma
16:29:36FromGitter<BigEpsilon> and see what it does
16:29:46FromGitter<BigEpsilon> thks

16:36:53FromGitter<BigEpsilon> yes I found it in msgs
16:37:05FromGitter<BigEpsilon> I'm adding it now

16:42:20FromGitter<BigEpsilon> what do you think about such a warning ?

16:46:13*yglukhov joined #nim
16:46:54FromGitter<BigEpsilon> in the loop
16:47:05FromGitter<BigEpsilon> you add a seq of size 0
16:47:16FromGitter<BigEpsilon> then try to access its element
16:47:32FromGitter<BigEpsilon> you most create it with size width
16:47:49FromGitter<BigEpsilon> world.add(newSeqint8 (0))
16:47:56FromGitter<BigEpsilon> becomes
16:48:25FromGitter<BigEpsilon> ```world.add(newSeq[int8](width))```
16:49:24SusWombat oh
16:49:41SusWombatshouldnt .add resize it?
16:50:08Yardanicowell just remove 0
16:50:08FromGitter<BigEpsilon> it resize the first seq
16:50:21FromGitter<BigEpsilon> the one that contains your height seqs
16:50:24Yardanicobut you don't actually need a nested seq here :)
16:50:39*yglukhov quit (Ping timeout: 248 seconds)
16:50:57tjyocoYeah a seq[tuple[int8, int8]] would be easier right?
16:51:09Yardanicowell I mean you can do that with just seq[int8]
16:51:13FromGitter<BigEpsilon> Yes if your code need to be fast, you better use a seq of size width*height
16:51:50FromGitter<BigEpsilon> easier maybe but slower than using a just a seq on int8
16:52:02FromGitter<BigEpsilon> of* int8

16:52:56Araq_BigEpsilon: I'm not that happy with your PR :-)
16:53:11tjyocoahh nice
16:53:18FromGitter<BigEpsilon> tell me about it :)
16:53:25Araq_you introduced special cases, overfitting the test suite
16:53:44Araq_instead you should have documented precisely why which test fails ;-)
16:54:01Araq_and then we can make these tests {.reorder: off.}
16:54:08FromGitter<BigEpsilon> Oh I did
16:54:09SusWombatThanks guys
16:54:14FromGitter<BigEpsilon> In the PR
16:54:26FromGitter<BigEpsilon> I explained why this tests failed
16:54:27Araq_must have missed this then
16:54:35YardanicoSusWombat, well I don't know if it would help you :)
16:54:44FromGitter<BigEpsilon> Its a test that uses the reorder pragma
16:54:45Yardanicobut yeah, it should work
16:55:06SusWombatYardanico, well i meant for pointing me to my mistake. your grid thing is intresting tho
16:55:32Yardanicowell it requires one multiplication and one addition at each index access
16:55:35FromGitter<BigEpsilon> @Araq_, see my last comment : https://github.com/nim-lang/Nim/pull/6326
16:55:39Yardanico*indexed access
16:56:10tjyococan anyone inform me as to what "Error: internal error: openArrayLoc: ResourceType" means?
16:56:25Yardanicotjyoco, some internal compiler error, report it
16:56:50*mahmudov joined #nim
16:57:22tjyocoYardanico, ah okay, because it was working one minute and haven't been able to get it to work since. Open an issue on GitHub then?
16:57:28FromGitter<BigEpsilon> My PR does not enable the reorder pragma by default, because at don't believe it should be, like I explained in the PR
16:57:55*loc8_ quit (Ping timeout: 246 seconds)
16:57:56Araq_BigEpsilon: it should be "opt-out", not "opt-in"
16:57:57Yardanicotjyoco, yeah, and share your code snippet with us here
16:58:42FromGitter<BigEpsilon> May be after more testing ?
16:59:28Araq_well I don't understand your remarks
16:59:39FromGitter<BigEpsilon> The Compiler compiles with reorder enabled but for that I had to be very strict in the reordering
16:59:40SusWombatoh ... just know i fully realize why my code didnt work ... embarrasing
16:59:47Araq_this test was written by me and used to work
17:00:19FromGitter<BigEpsilon> yes i can make it succeed, but it will break a lot of working code
17:01:10FromGitter<BigEpsilon> foo() is a command
17:01:22FromGitter<BigEpsilon> and defined() is another
17:01:47FromGitter<BigEpsilon> I have to keep their original order, other wise alot of code will be broken
17:02:11FromGitter<BigEpsilon> this introduces a circular dependency in that test
17:02:22FromGitter<BigEpsilon> so the original order is kept
17:02:27FromGitter<BigEpsilon> an the test fails
17:02:42Araq_1. within push/pop you can reorder
17:02:55FromGitter<Bennyelg> How Can I handel AsyncRequest? ⏎ newHttpClient is good enuge ?
17:03:01FromGitter<Yardanico> No
17:03:18FromGitter<Yardanico> You handle it with async http server
17:03:58FromGitter<BigEpsilon> Yes this can be enabled but needs some work
17:04:52Araq_2. which cycle prevents the reordering from working?
17:05:04Araq_it *used* to work :P
17:06:12tjyocoYardanico, this is my project with the error https://github.com/Tyler-Yocolano/nimbomb/tree/internal-error, I'm really not sure how to simplify it down for an issue report.
17:06:32FromGitter<BigEpsilon> when defined(testdef): depends on foo()
17:07:20FromGitter<BigEpsilon> and the definition of foo depends on whendep
17:07:41FromGitter<BigEpsilon> and when whendep depens on "when defined(testdef):"
17:08:48FromGitter<BigEpsilon> This is the circular dependency
17:10:31Araq_hmmm
17:10:39FromGitter<BigEpsilon> without this restriction some a lot of tests will fail
17:10:55Araq_ok I believe you
17:11:16FromGitter<BigEpsilon> I introduced all this restriction will trying to compile the compiler and make all the test succeed
17:11:51FromGitter<BigEpsilon> Is it possible to make the reordering during the semantic phase ?
17:12:07Araq_yeah but I feared the complexity :P
17:12:09FromGitter<BigEpsilon> when we would have real dependencies
17:12:35Araq_yes but when I tried that I had to rewrite all of the semantic pass
17:12:53FromGitter<BigEpsilon> I can tell you complexity escalated quicly when I started compiling system.nim :-)
17:13:11FromGitter<BigEpsilon> I understand
17:13:13Araq_system.nim is a special case
17:13:23Araq_we can disable it for system, as I said
17:13:58FromGitter<BigEpsilon> not just system, the compiler
17:14:50FromGitter<BigEpsilon> Its your call if you want to enable it by default, and disable it for specific cases
17:14:53*Jesin quit (Quit: Leaving)
17:15:20FromGitter<BigEpsilon> personaly I dont feel I need it for other cases than when using code generated by c2nim
17:17:04FromGitter<BigEpsilon> but top level commands will always be a problem for reordering
17:18:17Araq_well for now it'll stay disabled
17:19:17FromGitter<BigEpsilon> yes I think it should
17:19:25Araq_and c2nim can produce {.reorder: on.}
17:20:51FromGitter<BigEpsilon> do you have any plan to introduce forward type declaration into nim like for procs ?
17:21:06FromGitter<BigEpsilon> it is also a solution for the same problem

20:31:56TheManiaci.e. are there a few magic words that I would have to add to https://play.nim-lang.org/?gist=f7d0515324d892daf27087ff7e6c6f6c to make it compile
20:32:25TheManiac```Error: cannot instantiate Node
20:32:26TheManiacgot: (type N: enum, type T: string or seq)
20:32:26TheManiacbut expected: (N: enum, T: string or seq)``` is baffling me
20:33:53*loc8_ quit (Quit: WeeChat 1.9)
20:34:20TheManiacother than missing `type`, I feel I've satisfied the compiler god...
20:50:44FromGitter<zacharycarter> hrm let's say I have a bunch of constants declared and I want to select a random one - what would be the best way of going about implementing this?
20:51:12TheManiacput them in an array and select a random member of the array?
20:51:47FromGitter<zacharycarter> I was thinking of something a little more elegant - something that didn't me require to keep another listing of them
20:51:55FromGitter<zacharycarter> @Bennyelg please consult @dom96 on that one
20:52:22FromGitter<Bennyelg> @zacharycarter thanks.
20:52:34TheManiacIf they're all super related, you could make them the values of an enum?
20:52:54tjyocoI was about to suggest that
20:53:19TheManiacHopefully that says good things about us :)
20:53:41FromGitter<zacharycarter> could I write like macro that would let me identify all the constants in the file and then select one at random?
20:53:50tjyocoI'm not confident in my nim-fu at all
20:54:01FromGitter<zacharycarter> I'm a macro noob btw so if that question is laughable please just ignore it :P
20:54:21tjyocowhat type are your constants?
20:54:22TheManiacno doubt, but I'm going to ask the obvious question, why would you want to do such a thing?
20:54:37FromGitter<zacharycarter> I have this file -

20:55:25*TheManiac generally assumes you can do anything in macros if your fu is strong enough
20:55:49*TheManiac wonders if you could rewrite lex & yacc as a nim macro executed at compile time :)
20:56:17*TheManiac 's fu however is weak - sad 
20:56:36FromGitter<zacharycarter> https://play.nim-lang.org/?gist=7831cc33dca29209155fd1f3a50aafab
20:56:39FromGitter<superfunc> A macro could do that, not sure if its warranted here
20:56:57FromGitter<zacharycarter> ideally I have a proc / template / macro / something where I can say randomColor and return one of those const values
20:57:15FromGitter<zacharycarter> and I'd prefer to not have to redeclare them as another array / set / anything to keep maintenance low
20:57:56*Snircle joined #nim
20:58:01TheManiacThat definitely feels worth of a 'DefaultColors' enum
20:58:09TheManiacs/worth/worthy/
20:58:22tjyocoTheManiac, since your N is always an enum, can't you just take that out of the type definition and put it in the constructor
21:00:03TheManiacpossibly
21:00:53TheManiacIt's operating in an environment where there are several different types of enum floating around (representing different kinds of node), so it's out here to allow me to type check that it's the same enum as I'm expecting
21:01:51TheManiacand the N: enum is defined by the user, not in this file (if you see what I mean), hence needing to parameterise it as it's not known in advance
21:02:04tjyococould you create your own `==` operator and just compare the x.kind == y.kind
21:02:27TheManiacyes, but wouldn't that only get caught at runtime?
21:02:43TheManiacI want it to note compile if you pass in the wrong type of enum when you create a Node
21:02:48tjyocoOh i see what you mean now
21:03:47TheManiacI've obviously stripped this down, but I have functions like `dosomething[N, T](rule: Rule[N, T], node[N, T])`
21:04:07TheManiacso I need to make sure that Rule and Node have the same N & T

21:04:25FromGitter<zacharycarter> now for glyph rendering
21:04:29TheManiacs/node/node: Node[N, T]/
21:05:26TheManiac壟 (assuming that that's the output you were hoping for :))
21:06:10FromGitter<zacharycarter> meh I just wrote a random color proc to return values between 0 and 255 :P
21:06:14FromGitter<zacharycarter> but same effect
21:06:26FromGitter<zacharycarter> I'm trying to create a console / terminal emulator on top of my game engine for roguelikes
21:12:03*sz0 joined #nim
21:12:23FromGitter<zacharycarter> need to figure out how to center text over those rectangles now

21:39:39tjyocomaybe a dumb question but how should getters/setters look in nim
21:40:12FromGitter<zacharycarter> probably shouldn't have them
21:40:54tjyocoWhat do I do if I want a read-only type of variable
21:40:59FromGitter<zacharycarter> don't expose it
21:41:21FromGitter<zacharycarter> or declare it with let if that's what you mean
21:41:23FromGitter<zacharycarter> then it will be immutable
21:42:15tjyocoHow do you declare an objects field like that then?
21:43:25*miran quit (Remote host closed the connection)
21:43:40FromGitter<zacharycarter> ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=59b5b20c162adb6d2e8a10eb]
21:43:42FromGitter<zacharycarter> something like that
21:45:33tjyocoHm, I thought you meant I could declare a field using let or something like that. Because I have ref objects that I want to read some fields but not be able to change them. oh well
21:46:37FromGitter<zacharycarter> I don't think you can declare a field as being immutable
21:47:26*PMunch quit (Quit: leaving)
21:48:54*vlad1777d quit (Remote host closed the connection)
21:50:36FromGitter<zacharycarter> I imagine the way to do it is provide accessor procs to the fields you want and then don't expose them
21:51:22obadzdoes the document explain how new() works anywhere?
21:52:02tjyocoSo no shortcuts basically. Just getFoo*(bar: Bar) : type = return bar.foo; everytime
21:52:32tjyocoobadz, https://nim-lang.org/docs/system.html#new,ref.T
21:53:20obadztjyoco: thanks. so it takes a var ref T. how's that different from a ref T ?
21:53:43FromGitter<superfunc> @obadz that means its mutable
21:53:46obadzor is that like a var (ref T)
21:53:55FromGitter<zacharycarter> (https://files.gitter.im/nim-lang/Nim/QiMm/Screen-Shot-2017-09-10-at-5.53.39-PM.png)
21:53:55obadzsuperfunc: aren't all refs mutable?
21:54:47tjyocozacharycarter, that looks harder to understand than dwarf fortress
21:55:12FromGitter<zacharycarter> well it's totallyr andom atm
21:55:40tjyocojust messing around lol
21:55:42FromGitter<zacharycarter> :P
21:55:59FromGitter<zacharycarter> I guess I can start coding the roguelike now?
21:57:08tjyocoare you just using sdl2
21:57:30*mahmudov quit (Ping timeout: 240 seconds)
21:58:48FromGitter<zacharycarter> nope
21:58:49tjyoco@obadz I think when something says var in front that means that the object you pass is changed directly. Not having that creates a copy and changes only the copy
21:59:14FromGitter<zacharycarter> tjyoco: this uses my game engine https://github.com/zacharycarter/zengine
21:59:35obadzis var ref T the same as var (ref T) ?
21:59:49obadzi.e. it's really a mutable cell containing a reference?
21:59:59obadzwould kind of be a **T in C
22:02:21obadzhttps://gist.github.com/obadz/c331c7657de7877c58658d04c1e4e56c ⇐ finalizer doesn't seem to be called. Is that normal?
22:04:31FromGitter<mratsim> @ipjk, @Yardanico: you can also copy paste the code from andrea’s linalg and neo (static array and seq, your choice) and rename the field.
22:09:33FromGitter<zacharycarter> obadz: I has no idea... it looks to me like it should be getting called but Araq or someone who knows the language better than I do would be a better person to ask
22:19:37FromGitter<superfunc> the vscode plugin is pretty nice, im enjoying it over the nim.vim one, and their vim emulation is solid enough for me 
22:20:35adam12Does ctrl-z (suspend) insert any characters? That's the hardest part of me switching editors (and finding :wq in files that don't compile :\)
22:20:41obadz@superfunc: have you tried this one: https://github.com/baabelfish/nvim-nim ?
22:21:12adam12obadz: Oh very nice. I just installed zah/nim.vim today.
22:21:21obadzadam12: me too :)
22:21:36FromGitter<superfunc> @obadz: I havent, I saw it hadn't been updated in forever so I kinda didnt bother
22:23:04FromGitter<superfunc> I'll give it a shot today
22:23:18obadz(I haven't tried it myself)
22:25:19*FromGitter * superfunc rolls the dice
22:38:27FromGitter<cabhishek> @adam12 did zah/nim.vim work as expected? I couldn't get it work for error checking and code navigation
22:41:18adam12@cabhishek Only spent a few minutes with it so far. Haven't tried error checking or code navigation. Syntax highlighting looks OK
22:41:40adam12I haven't touched nim since 2015. Just taking another look at it now and realized I needed syntax highlighting :)
22:44:39FromGitter<cabhishek> @adam12 ok! well, syntax highlighting works great. But that's all I could get it to work out of the box.
