00:00:20FromGitter<Tatazaki_twitter> So I have a file called 'config.nim' in the root directory of my project, and a file called 'color.nim' in a subfolder called 'visualworks'. How would I go about importing config.nim in color.nim?

00:36:32FromGitter<zacharycarter> thanks @cabhishek kind of like that... I'm not sure scanf is the right tool for what I'm trying to do
00:37:47FromGitter<zacharycarter> basically I'm trying to capture all the text between two double quotes
00:38:06FromGitter<zacharycarter> without resorting to pcre etc
00:40:14FromGitter<Tatazaki_twitter> does it error or does it keep running?
00:40:39FromGitter<zacharycarter> does what error?
00:40:54FromGitter<Tatazaki_twitter> your scanf.
00:41:35FromGitter<zacharycarter> well that's the thing I'm not sure how to write the scanf to do what I want
00:42:35ryu0"\"%[^"]\"" ?
00:42:52FromGitter<zacharycarter> I think that'd work for C's scanf
00:42:56FromGitter<zacharycarter> not sure about Nims but I'll try
00:45:17ryu0appears nim's scanf has nothing like it. maybe you can try writing a function to extend. it appears to support it.
00:45:20ryu0${} and $[]
00:47:08FromGitter<zacharycarter> I guess I"ll have to
00:47:25FromGitter<zacharycarter> I figured there'd already be an easy way to do this

07:25:00deavmiThat moment when you do your first operator overload and make the most useless use out of `$` :). I'm so happy.
07:30:37FromGitter<Bennyelg> Hey Guys, How Do I handle Future object of asyncrequest
07:30:47FromGitter<Bennyelg> I want to read it when it returnes
07:32:05FromGitter<Grabli66> let result = await yourFuture ? :)
07:32:16FromGitter<Bennyelg>
07:32:19FromGitter<Bennyelg> :P
07:32:24FromGitter<superfunc> you can also set a callback
07:32:50FromGitter<superfunc> ``` proc (future: Future[string]) = ⏎ echo("value: ", future.read)``` [https://gitter.im/nim-lang/Nim?at=59b63c22210ac26920180a41]
07:33:02livcdI wonder how much is the js backend used
07:33:32FromGitter<Bennyelg> ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=59b63c4c177fb9fe7ea6916b]
07:33:35FromGitter<Bennyelg> what is wrong ?
07:34:30FromGitter<Grabli66> You can use await only in async proc. You need write let res = waitFor response
07:34:50FromGitter<Bennyelg> oh Now I undertstand the concept
07:35:00FromGitter<Bennyelg> So I need to compile it --threads:on?
07:35:07FromGitter<Grabli66> No
07:35:26FromGitter<Grabli66> Async does not use threads
07:35:38FromGitter<superfunc> Async is for concurrency, not parallelism
07:37:11deavmiHow to I create a setter for a Human object (also second question, is there a root like top-type for all objects via inheritance for Nim like in Java, D etc.??)
07:38:24*PMunch joined #nim
07:39:14deavmiI have a `proc setAge(obj: Human, age: int) = ` and the body is `obj.age = age`. Gives a compilation error that such an assignment is not allowed
07:39:45FromGitter<superfunc> deavmi: try `proc setAge(obj: var Human, age: int) = ` as the type sig
07:40:00FromGitter<superfunc> deavmi: by default, that param is immutable, so it can't be assigned to
07:40:16deavmiOh, and var what does that do? Doesn't that take in a refernce or something?
07:40:19deavmiTo the object?
07:40:26deavmior just mutable?
07:41:18deavmiAh that works. Thanks
07:43:39FromGitter<superfunc> deavmi: np, https://nim-lang.org/docs/tut1.html#procedures-parameters for more info
07:43:58FromGitter<superfunc> I'm not sure on your second question, don't really write in OO style personally
07:44:26deavmisuperfunc: Thanks tho :)
07:44:51FromGitter<superfunc> deavmi: happy to help where I can
07:45:58deavmiAnd that's why I love programming language communities. They have the best people (maybe besides Java, they're alright)

13:46:33Yardanicotjyoco, well you shouldn't use strings in macros for code generation
13:46:37Yardanicoyou should use AST

13:49:33tjyocogotcha
13:49:38YardanicoI'll fix your code now
13:50:04tjyocothank you!
13:50:27Yardanicowell your code isn't valid because you're trying to make a proc like this
13:50:38Yardanicoproc getx(): x = x
13:50:45Yardanicoso it would return "x" variable of type "x"
13:51:00tjyocoyeah, how would I get x's typedesc?
13:51:23Yardanicoyou would use AST for that :)
13:52:30Yardanicowell I would still do it
13:52:44tjyocoI'll give it a shot. So just dumptree: >insert example code and duplicate what pops out?
13:53:15Yardanicowell no
13:53:24Yardanicodumptree is used for getting AST
13:53:41Yardanicoyou can use dumpAstGen
13:53:48tjyocowell, yeah sorry I worded it wrong. But that would help me with structuring the statements correctly
13:53:49Yardanicobut it's generally better to write code in macros by hand
13:53:57Yardanicoe.g. using stuff like newProc
13:54:13tjyocoI haven't used the dumpAstGen, ill try that

15:05:34spicaHey guys. I'm a noob playing with nim. A question. Why does a continue inside a block without look give (SIGSEGV: Illegal storage access. (Attempt to read from nil?))? A bug or a feature?
15:05:59spicahttps://pastebin.com/p6n0nnaL
15:06:40spicablock without loop*
15:09:01Yardanicospica, because it seems to be a compiler error
15:09:05Yardanicoreport it on github
15:09:11Yardanicobut using "continue" in a block is pointless
15:09:32Yardanico"continue" is only used in "while" and "for"
15:09:35Yardanicoloops
15:09:58spicaI know it's pointless, I was trying to see what happens, I was trying to emulate a loop using block and labeled continue, but it didn't work
15:10:15Yardanicospica, well there's no labeled continue in nim AFAIK
15:10:29Yardanicobut I might be wrong
15:10:33spicawell, I know now. There's in java afaik, so I was just curious
15:12:12livcdI need to parse xmls and save the output as kv pairs in a database (or convert to huge simple json of { "lah":"lah","lah":"lah",...}. The xmls can have arbitrary structure and what I am interested in would be to just grab all xmlnodes and get values

15:13:19Yardanicowell https://nim-lang.org/docs/parsexml.html is a very high performance XML/HTML parser
15:13:23livcdYardanico: yes but don't i need to define the data structure first ? (as in knowing how it will look like?)
15:13:37Yardanicolivcd, no, you don't, if you just want to grab all nodes

16:19:17FromGitter<Grabli66> Yes
16:19:27Yardanicothen you need to make sure you're not using any global variables

16:40:28FromGitter<adamrezich> weird question: there shouldn't be anything wrong with setting a table to nil, right?

16:44:30FromGitter<adamrezich> but yeah
16:44:37FromGitter<superfunc> Sure yeah that should be fine
16:44:54FromGitter<adamrezich> well it's causing an error very rarely and idk why
16:45:16*relax joined #nim
16:45:23FromGitter<superfunc> Hmm, what kind of errors?
16:46:52FromGitter<adamrezich> well so I'm making a complex game engine, and new `Elem`s (entities) are created in the memory manager with a proc `result = castptr Elem (alloc(sizeof(Elem)))`—first off, is that bad?
16:47:34FromGitter<superfunc> Stepping back, are you sure you need to manage the memory yourself?
16:47:35Yardanicowell you really need custom memory management?
16:47:38Yardanicoyeah
16:47:48FromGitter<superfunc> It might be better to just controll gc passes instead
16:47:49FromGitter<adamrezich> I'd like to, for game performance :\
16:47:55Yardanicowell you wouldn't lose any performance
16:48:01Yardanicoyou can set max GC pause for GC
16:48:13Yardanicohttps://nim-lang.org/docs/gc.html
16:48:28Yardanicothere's realtime gc
16:49:02YardanicoThe GC is only triggered in a memory allocation operation. It is not triggered by some timer and does not run in a background thread.
16:50:00Yardanicobut yeah, I don't know about much about Nim GC performance because I don't use it for realtime stuff (I don't write software which requires realtime) :)
16:51:20Yardanicoyou already can, for example, specify the size of a seq, so it wouldn't reallocate memory
16:53:02FromGitter<adamrezich> well one of the main goals of my engine is to experiment with object hierarchies and component-based design, in a way that compromises ease of use and performance. it's hard to explain but instead of having a global collection of entities and components or whatever, Elems are created in a hierarchy (with pointers), and they have pointers to Comps (components). traditionally in C++ I'd allocate the Comps in a global
16:53:02FromGitter... collection per Comp subclass, but I'm experimenting with having Elems in the hierarchy contain the Comp allocators. thus, I can make an Elem called "world", attach a "PhysicsRealm" Comp to it, then add child Elems to "world" with "CircleCollider" Comps, and it'll allocate them in an allocator in the "world" elem, s ... [https://gitter.im/nim-lang/Nim?at=59b6bf6e177fb9fe7ea9b1a7]
16:53:14FromGitter<adamrezich> so it could be that I'm having a GC issue, because otherwise it works flawlessly :(
16:54:25Yardanicowell you can make a bug report if you've encoutered some gc bug
16:54:51FromGitter<superfunc> Yeah, my rec would be to go through standard ref facilities and report any issues you run into, I think it should be possible
16:55:33FromGitter<adamrezich> lemme trigger the error so I can show you real quick
17:00:18FromGitter<adamrezich> github: https://github.com/rezich/nch error, caused randomly by spamming spacebar to fire a ton of bullets: https://pastebin.com/cnFxeLfj
17:00:43FromGitter<Yardanico> Well it's most probably a GC bug
17:01:53FromGitter<superfunc> The traceback is in gc.nim, but it'd be hard for me to discern rn since its all going through manual memory management
17:02:10FromGitter<superfunc> Sorry I don't have much time to look at the moment
17:03:38FromGitter<adamrezich> it's also important to note that i'm allocating Comps by doing `alloc(sizeof(T) * compReg.perPage)`. it's a paged memory manager, allowing the user to specify how many of each specific type of Comp they want per page of each Comp. i.e. you want like 2 PlayerControllers, but 2048 CircleColliders, etc.
17:03:59FromGitter<adamrezich> but it works 99% of the time, and only crashes when I create a bunch of stuff really fast :\
17:04:29FromGitter<superfunc> I'd wait for @Araq to be around, he'd probably have the clearest understanding to help you there
17:05:15Yardanicoyeah :)
17:06:21FromGitter<adamrezich> k, sounds good
17:06:51FromGitter<adamrezich> I just tried `--gc:v2` and it does the same thing, with the same error lines in gc.nim, but with the error lines from assign.nim omitted o_O
17:07:24Yardanicotry mark and sweep gc
17:07:44FromGitter<adamrezich> isn't that gc:v2?
17:08:22Yardanicono
17:08:40Yardaniconim also has support for boehm gc and go gc :)
17:09:39FromGitter<superfunc> `--gc:markAndSweep`
17:09:53Yardanicoyeah
17:11:13FromGitter<adamrezich> it just makes it crash sooner :(
17:11:21Yardanicowhat about boehm gc? :)
17:11:27FromGitter<adamrezich> I can almost guarantee it's because I'm using a combination of my own alloc stuff and also nim's refs
17:11:28Yardanicobut you should have boehm installed on your PC
17:11:36FromGitter<adamrezich> how do I do that?
17:11:38FromGitter<superfunc> I'd guess that its an error in your memory management
17:11:50Yardanicoyeah, you should also use some GC_ref and GC_unref
17:11:52FromGitter<superfunc> Just manifests itself in the gc's
17:12:34FromGitter<adamrezich> ooh didn't know about gc_ref and gc_unref
17:15:23FromGitter<Grabli66> Why my console programm can crash on ctrl+c ? There is no exception, just dialog window that my process crashed. :(
17:23:01AraqGabli66: which OS? signal handlers are super unsafe and I don't care about them

17:56:22FromGitter<zacharycarter> @adamrezich well I saw you using sdl2 etc so I was just thinking instead of using that renderer maybe you can use something built on top of it already

18:00:23spicaHi guys. I'm a bit confused. "var x = int32(someOtherVar)". How does this work? int32 does't seem to be a function in system? Alias for toInt or something?
18:01:19FromGitter<zacharycarter> @adamrezich yeah I'd highly suggest giving zengine a spin, and checking out the code examples to see what I mean, it's a very unobtrusive library for prototyping so it doesn't dictate much beyond you using SDl2 | OpenGL
18:01:26FromGitter<zacharycarter> @spica thats' the same as writing

18:01:55FromGitter<zacharycarter> it's a cast
18:02:06FromGitter<zacharycarter> or coercion I guess
18:02:48spicawell it's frigging confusing... number.int, int(number) number.int() toInt(number)

18:04:13FromGitter<adamrezich> @zacharycarter yeah will do, for now I'm fine with just drawing lines and circles but as soon as I want to do more complex stuff I'll give zengine a try. it should be super simple to make a "ZengineRenderer" component in my engine, to replace the simple (SDL) Renderer component. ⏎ ⏎ since I know next to nothing about graphics programming: does zengine let you do stuff with shaders? b/c I know you can't with just

18:11:21FromGitter<zacharycarter> nope!
18:11:29*d10n-work joined #nim
18:11:55FromGitter<adamrezich> erm, I thought I saw one, maybe I didn't
18:12:20FromGitter<zacharycarter> I made one a while ago but just deleted it as it's not really useful
18:12:58FromGitter<adamrezich> could've sworn I saw one the other day, maybe not
18:22:49FromGitter<adamrezich> when do you use `object` vs. `object of RootObj` for defining types?
18:25:14FromGitter<superfunc> If you want to inherit from it, see: https://nim-lang.org/docs/manual.html#types-tuples-and-object-types
18:25:27FromGitter<superfunc> The lower area of that section discusses RootObj
18:26:00FromGitter<superfunc> Key bit "Objects that have no ancestor are implicitly final and thus have no hidden type field."

18:53:23FromGitter<superfunc> From the same section I linked to
18:53:24Yardanicothere's a description
18:56:02FromGitter<adamrezich> yeah I read that I'm just trying to wrap my mind around it
18:56:43FromGitter<adamrezich> what's the point of named tuples?
18:57:05FromGitter<superfunc> I'd represent a simple type like a point2d with a named tuple, so I have x and y fields.
18:57:21FromGitter<superfunc> But I have no need for information hiding or inheritance with such a type.
18:58:22FromGitter<adamrezich> so, because you don't use the name of the tuple to instantiate it, is tuple instantiation just pattern-matched with tuple types then?
18:58:51Yardanicoyes
18:58:55FromGitter<adamrezich> i.e. you have to declare all fields of it upon instantiation in order to make it an instance of the desired tuple type, and not just some new tuple type
18:59:08Yardanicowell
18:59:13Yardanicoif your proc returns a tuple for example
18:59:20Yardanicoyou can assign separate fields by using result variable
18:59:45FromGitter<adamrezich> ah, ok. but when you use assignment, you have to set all the fields, right?
19:00:27*Matthias247 quit (Quit: Matthias247)
19:01:24FromGitter<superfunc> Yeah
19:02:11FromGitter<adamrezich> cool. what happens when you do as @Yardanico said above, and have a proc that returns a tuple, but you don't declare all fields of it? are they zeroed or uninitialized?
19:02:36Yardanicoall value types contain binary zero
19:02:42Yardanicoall ref types are nil
19:03:01FromGitter<adamrezich> gotcha
19:03:08FromGitter<superfunc> They get there zero value yeah

19:06:55Yardanicoe.g. all number types like int8, int16, int32, int64, float32, float64
19:07:06FromGitter<superfunc> Oh yeah heh, forgot about that

19:24:57FromGitter<adamrezich> is it possible to write a constructor for a `ptr object` type without using alloc()?
19:25:27Yardanicowell it's a raw pointer
19:25:39Yardanicobut IDK :)
19:26:00FromGitter<adamrezich> right, so it needs a cast, which is ugly too. but then again, ptrs are inherently ugly (:

20:05:28FromGitter<mratsim> @adamrezich iirc @Araq had some in-depth link about Entity COmponent System and game design
20:06:05FromGitter<mratsim> I found an implementation tuto in C: https://www.gamedev.net/articles/programming/general-and-gameplay-programming/implementing-component-entity-systems-r3382
20:06:48FromGitter<zacharycarter> ECS = evil
20:06:53FromGitter<mratsim> and a repo with examples: https://github.com/sosolimited/Entity-Component-Samples (note I’m not a game programmer so judge the quality by yourself, it was just in my archives)
20:06:54FromGitter<zacharycarter> fyi
20:07:22FromGitter<zacharycarter> I'm not sure if @adamrezich is designing an ECS or more of a scene graph style node component system
20:08:24FromGitter<mratsim> quote: "well one of the main goals of my engine is to experiment with object hierarchies and component-based design, in a way that compromises ease of use and performance. it's hard to explain but instead of having a global collection of entities and components or whatever, Elems are created in a hierarchy (with pointers), and they have pointers to Comps (components). ..."
20:09:54FromGitter<zacharycarter> maybe conflating ideas here - ECS's tend to be geared towards organizing game logic
20:09:57FromGitter<adamrezich> yeah I'm just experimenting with ideas to see what works best. I've made several component-based frameworks in C, C++, and C# before, and I'm trying to figure out a good tradeoff between ease of use, performance, and Nimishness
20:10:04*vlad1777d joined #nim
20:10:20FromGitter<adamrezich> that's the thing, I'm designing a scene graph and ECS rolled into one
20:10:21FromGitter<zacharycarter> but there are also scene graphs that tend to employ node / component hierarchies
20:10:28FromGitter<zacharycarter> ala unity32
20:10:31FromGitter<zacharycarter> 3d*
20:10:38FromGitter<zacharycarter> ah okay interesting
20:11:02FromGitter<zacharycarter> I've never really found an ECS I enjoy using, maybe yours will change my perception of them :) (I hope)
20:11:07FromGitter<mratsim> wasn’t there a #nim-games channel btw?
20:11:12FromGitter<zacharycarter> if not we need one
20:12:37FromGitter<mratsim> Well, soon you won’t be needed anyway ;) https://www.theverge.com/2017/9/10/16276528/ai-video-games-game-engine
20:13:49FromGitter<zacharycarter> yeah once programs start writing programs we're all screwed
20:13:51FromGitter<mratsim> When I get Arraymancer up to speed, I’m definitely using it for game AI. Google and Blizzard released an AI API for Starcraft 2 for example

20:38:42obadzok I think I get it
20:38:44obadzthanks
20:40:32FromGitter<adamrezich> @mratsim thanks for looking anyways :)
20:41:50obadzis it allowed to have a ptr to an object that has a ref member? does the GC keep track of the ref member?
20:42:07*nitely joined #nim
20:46:43FromGitter<mratsim> It is allowed, but don’t do wild modifications using the pointer, they won’t be checked by the compiler
20:49:04FromGitter<mratsim> Except for C intro, in my experience, you don’t really need pointers in Nim. I even benchmarked 2 equivalent implementation of matrix multiplication one with pointers the other with seq + offset, and seq + ofset were faster. (I suppose the compiler could optimize those more aggressively)
20:49:20FromGitter<mratsim> C intro*
20:49:28FromGitter<mratsim> interop*
20:51:45FromGitter<mratsim> (matrix multiplication is a O(n3) memory bound operation, the faster your memory access are, the faster you get your result, the CPU compute is less important that getting data in the cache fast)
20:53:01*claudiuinberlin quit (Quit: Textual IRC Client: www.textualapp.com)
20:53:39obadz@mratsim: sure I'm not looking at ptr for speed but only because it seems to be the only way to share memory across threads?
20:54:26FromGitter<superfunc> channels are available for that
20:54:48obadzdon't think it's appropriate for sharing a 1Gb array
20:55:16FromGitter<mratsim> You can use pointers no worry
20:55:52FromGitter<superfunc> oh yeah, didnt realize the size
20:56:42obadzI'd still want to use channels to control the flow of what's going on but eventually there needs to be something in some shared heap
20:58:15FromGitter<superfunc> yeah `allocShared` would be what you'll want
20:59:43obadz@superfunc: how can I copy an object to an allocShared area?
21:01:25FromGitter<zacharycarter> https://play.nim-lang.org/?gist=0ea04dc15553f552d20450d3cd148c68 obadz
21:02:16obadz@zacharycarter: very nice, thanks!
21:02:56FromGitter<zacharycarter> sure thing
21:03:36FromGitter<superfunc> Yep, the locks module will probably come in handy for you too
21:03:58FromGitter<superfunc> The guard pragma is neat and useful for ensuring you grab a lock when accessing

21:14:52FromGitter<adamrezich> https://play.nim-lang.org/?gist=6abc1e40b716bcb0c13c76edafc69424 is the syntax on line 31-32 here possible with templates and/or macros? (I haven't messed around with macros at all yet)
21:16:19FromGitter<superfunc> @adamrezich yeah
21:16:28FromGitter<superfunc> Easiest way to find out is just use dumpTree
21:16:47FromGitter<adamrezich> where/on what?
21:17:05FromGitter<superfunc> ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=59b6fd51bc464729741fd10d]
21:17:40FromGitter<superfunc> If its valid syntax, dumpTree will succeed and spit out its AST representation at compile time
21:18:13FromGitter<superfunc> It doesn't need to be a compilable snippet, since you're just dumping the parsed AST
21:18:55FromGitter<superfunc> Then its just a matter of writing macros that will build up that AST
21:19:59FromGitter<adamrezich> oh ok
21:20:04FromGitter<adamrezich> so a template won't work here then?
21:21:08FromGitter<superfunc> I didn't look too closely at what the code is doing. If the generation needs to be procedural, its a macro, if its simple substitution, it can be a template
21:22:49FromGitter<adamrezich> basically I want to make it so I don't have to type `proc (elem: Elem) =` when declaring a thing that takes a proc with that signature, if possible
21:23:45FromGitter<krux02> well I don't really understand what you want exactly, but it sounds like it is possible
21:24:06FromGitter<adamrezich> in that example, I can do ⏎ ⏎ ```register(MyComp, proc (elem: Elem) = ⏎ echo $elem ⏎ )``` ⏎ ⏎ , but I 'd like to be able to write ... [https://gitter.im/nim-lang/Nim?at=59b6fef6177fb9fe7eab26cc]
21:24:16FromGitter<krux02> but maybe you want the lambda syntax
21:24:18FromGitter<adamrezich> (whoops messed up some backticks there)
21:24:28FromGitter<adamrezich> from future?
21:24:48FromGitter<superfunc> Yeah, I'd just use the stuff from future
21:25:01FromGitter<adamrezich> how do you make it not have a return value though?
21:28:51FromGitter<superfunc> I would presume something like `p: (T) -> void`
21:30:44FromGitter<zacharycarter> the reason your example doesn't work @adamrezich is that elem isn't defined anywhere
21:31:18FromGitter<adamrezich> line 21 is where I tried to define it, thinking that's how templates work

21:42:50FromGitter<adamrezich> yeah not quite. it's ok though, I'll delve into macroland with dumpTree eventually

22:45:16SusWombatwhat is the difference between frag and zengine?
22:45:52FromGitter<zacharycarter> frag = very complex with lots of integration points between different libraries, also abandoned
22:46:14FromGitter<zacharycarter> zengine = stupid simple, akin to XNA | Allegro, with basic 2d and 3d primitive drawing
22:46:34SusWombatwhat libs does it use?
22:46:38FromGitter<zacharycarter> it's meant to be a prototyping library, but it's capable of whatever you're willing to write on top of it really
22:46:45FromGitter<zacharycarter> SDL2, OpenGL Assimp
22:47:15FromGitter<zacharycarter> oh and Nuklear for IMGUI
22:47:29FromGitter<zacharycarter> but that's totally optional
22:47:30SusWombatdoes it support shaders?
22:47:34FromGitter<zacharycarter> yup!
22:47:39FromGitter<zacharycarter> along with skeletal animation
22:47:46SusWombatHm might need to check it out
22:47:57FromGitter<zacharycarter> it's really a glorified port of Raylib to Nim
22:48:05FromGitter<zacharycarter> with my own take and def-pri-pubs take on certain things
22:48:24SusWombatDoes it have "debugging"?
22:48:39FromGitter<zacharycarter> hrm what do you mean by that?
22:48:55SusWombati mean errorhandling/errormessages
22:49:19FromGitter<zacharycarter> oh, yeah it does

22:50:07FromGitter<zacharycarter> I tried to plug error messages in where I thought they were sensible
22:50:30FromGitter<zacharycarter> it probably needs a lot more

23:15:56FromGitter<zacharycarter> they're just on github
23:16:03subsetparkwell get on it man, how else am I gonna write my roguelike now?
23:16:21FromGitter<zacharycarter> just use the git repo!
23:16:29FromGitter<zacharycarter> https://github.com/zacharycarter/blt-nim
23:17:32subsetparkwhat, you want me to copy in the file? what is this 1996
23:17:59FromGitter<zacharycarter> no no no
23:18:05FromGitter<zacharycarter> are you using nimble?
23:18:19subsetparkyeah - can you point `requires` at a .git URL/
23:18:25FromGitter<zacharycarter> yessir
23:18:58subsetparkI never knew that! Super cool
23:19:01FromGitter<zacharycarter> subsetpark - you were curious about AWS lambda and Nim too right?
23:19:06subsetparkThat makes my professional life easier too
23:19:21subsetparkYou could say it was a morbid curiosity, maybe
23:20:29*Matthias247 quit (Read error: Connection reset by peer)
23:20:43FromGitter<zacharycarter> a couple folks in here (including myself) now have Nim code running in lambda being called from python
23:20:50FromGitter<zacharycarter> I'm about to go to production at work with it
23:21:31FromGitter<zacharycarter> we used https://github.com/jboy/nim-pymod to make it work
23:23:46FromGitter<zacharycarter> anyone want to help me re-write this in Nim?
23:23:58FromGitter<zacharycarter> ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=59b71b0e319100804e22b064]
23:24:22FromGitter<zacharycarter> because I'm getting hung up on split_sets
23:25:23subsetparkactually, i'm working on the opposite solution
23:25:35subsetparkAt work I use ctypes to call Nim from Python
23:26:07subsetparkso I am gonna put together a simple ntypes library that provides ctypes for Nim types
23:26:53FromGitter<zacharycarter> that will be handy
23:27:06subsetparkthen you compile the nim code to C and distribute the C sources with the Python package; you don't need the nim compiler to install the python package

23:51:29FromGitter<zacharycarter> yup
23:51:41def-pri-pubcool
23:52:25def-pri-pubHow is the 3D texture example coming along? That's probably the next thing that blocking me. I'm going to work on the ZSprite tool in the meantime.
23:52:48FromGitter<zacharycarter> I have questions about the 3d texture example
23:53:01FromGitter<zacharycarter> did you see the screenshot I posted the other day?
23:53:44FromGitter<zacharycarter> https://files.gitter.im/nim-lang/Nim/MJe9/thumb/Screen-Shot-2017-09-10-at-8.13.19-AM.png
23:53:45def-pri-pubno,
23:53:52FromGitter<zacharycarter> do you want something like that?
23:53:54def-pri-pubdats tiny
23:53:58def-pri-pubreally tiny
23:54:16FromGitter<zacharycarter> hrm let me try to find the og picture
23:55:01FromGitter<zacharycarter> https://files.gitter.im/nim-lang/Nim/MJe9/Screen-Shot-2017-09-10-at-8.13.19-AM.png
23:55:19def-pri-pubYeah, that's what I'd like
23:55:23FromGitter<zacharycarter> okay
23:55:32def-pri-pubCan I at least rotate/orient the texture in all three directions?
23:55:35*yingjun joined #nim
23:55:41FromGitter<zacharycarter> I need to add billboarding for that
23:55:48FromGitter<zacharycarter> I'll work on this tonight
23:55:50def-pri-pubAlso, I assume transparnecy works?
23:55:57FromGitter<zacharycarter> good question
23:56:06FromGitter<zacharycarter> it needs to
23:56:21FromGitter<zacharycarter> yeah I'll get all this straightened out tonight
23:56:36def-pri-pubEh, I don't think you need bill-boarding per-se. It's moreso that you need orienting for bill-boarding
23:56:45FromGitter<zacharycarter> right
23:56:47FromGitter<noctisdb> Ive just been tinkering with moving things around, and editor support for brackets (closest thing to atom like I could find for 32 bit)
23:56:50def-pri-pubCan you post your work to the repo on a non-master branch?
23:57:04FromGitter<zacharycarter> well I accidentally deleted the above example
23:57:07FromGitter<zacharycarter> let me recreate it
23:57:10FromGitter<zacharycarter> and I'll make a new branch
23:57:23def-pri-pub¯\_(ツ)_/¯
23:57:34FromGitter<zacharycarter> pretty much
23:57:43def-pri-pubI do think an actual function should be formalized in zgl.nim
23:57:46def-pri-pubI can do that for you
23:58:28def-pri-pubI'll probaby need to shove some OpenGL code anyways in `SpriteBatch` like I orignally planned.
