00:08:15FromDiscord<asm95> Hi, doesn't nim has a showcase page of programs like a text editor, game, website or other application?
00:08:40FromDiscord<asm95> I found a awesome page but with just libraries like SDL bindings etc
00:09:04FromDiscord<ElegantBeef> In january we've started a `this month with nim` which shows some of that stuff
00:09:19FromDiscord<ElegantBeef> Can see them here https://nim-lang.org/blog.html
00:09:24FromDiscord<asm95> In reply to @ElegantBeef "In january we've started": Hi, but the blog doenst have a filter for those posts?
00:09:36FromDiscord<ElegantBeef> It does not
00:09:52FromDiscord<ElegantBeef> Only 3 blogs for it so far so not a big deal 😛
00:10:10FromDiscord<asm95> In reply to @ElegantBeef "It does not": Oh it would be nice to make a category for those posts
00:10:18FromDiscord<ElegantBeef> Well go ahead 😄
00:10:41FromDiscord<asm95> Don't you agree?
00:10:53FromDiscord<ElegantBeef> I just mean it's all OSS, so you can be the change you want in the world
00:11:22FromDiscord<asm95> In reply to @ElegantBeef "I just mean it's": If someone actually accepts the pull request
00:11:48FromDiscord<asm95> But thank you anyway, it was very helpful
00:11:58FromDiscord<garett> @ElegantBeef Thanks, that works great!
00:12:08FromDiscord<ElegantBeef> No problem
00:12:33FromDiscord<ElegantBeef> In reply to @asm95 "If someone actually accepts": They're generally very receptive to improvements to encourage showcase/growth
00:16:49FromDiscord<ElegantBeef> Well garret i've made an issue for it, so rest easy 😛
00:18:21FromDiscord<checkersai> I wanna write an ECS library but whenever I start reading about different implementations I just feel stupid
00:19:46FromDiscord<ElegantBeef> Well there are like 100 difference ECS implementations in Nim
00:19:55FromDiscord<ElegantBeef> So you have a ton of different reference material
00:20:42FromDiscord<ElegantBeef> I joke about 100 of course, but yea there are a fair bit https://github.com/search?p=1&q=ECS+language%3Anim&type=Repositories

04:17:35FromDiscord<checkersai> Also, why isn't `seq.len` a `uint`?
04:19:37FromDiscord<ElegantBeef> cause uints are scary, and no it has an errata, so it's still fine if you refer to that

06:06:24saemBeef what happens when you assign to a var/let that has an explicit type within the case statement so `let b: B = left`, inside a case over `A`?
06:06:44FromDiscord<ElegantBeef> It doesnt do any reasoning there
06:08:01*Gustavo6046 quit (Ping timeout: 265 seconds)
06:09:37FromDiscord<ElegantBeef> Though i suppose it might be able to
06:12:42saemThere is a reason I didn't go down this road, the inference information propagating like that breaks things.
06:13:34FromDiscord<ElegantBeef> Hey i was just toying around after making the macro i doubt this will go into the compiler
06:15:01saemYou're on track to figuring it out though.
06:15:18FromDiscord<ElegantBeef> Wait this isnt a bodge?!
06:16:06saemWell the context isn't the right way to pass it along, but you are seeing the data flow regardless -- that's a good thing.
06:16:40FromDiscord<ElegantBeef> Lol, the alternative is to pass the type through all the procedures and that felt dirtier
06:17:19saemWell, there is the AST.
06:20:38FromDiscord<ElegantBeef> Considering my understanding of the compiler that doesnt mean much 😛
06:24:27saemI was going to say shove in nodes as a start via a new field.
06:56:41FromDiscord<ElegantBeef> Well you encouraged me to do it using an extra field on Nodes and it is now on par 😄
06:56:43saem@ElegantBeef: a long time ago I had a similar thought about using context. Maybe instead of shying away from caseTyp, push into it. Everytime there is any situation where narrowing information about types is available push and pop it.
06:57:28FromDiscord<ElegantBeef> I'm 100% certain anyway i approach this will be "wrong"
06:58:02saemGot a diff of the node variety?
06:58:27FromDiscord<ElegantBeef> I just added a `expected: PType`
07:00:50saemI should sleep tonight, if you want to chat about it/work on it tomorrow I'll be about.
07:02:41FromDiscord<ElegantBeef> Ok, well now it works properly afaict
07:04:53FromDiscord<ElegantBeef> https://github.com/nim-lang/Nim/compare/devel...beef331:sillyinfercase Diff if anyone else is interested 😄
07:12:35saemwith a bit more love that generalises to cover a whole lot more situations. :D
07:14:34FromDiscord<ElegantBeef> Yea supports that `: B = left` so clearly better and smarter, i was mostly just scared of adding a value to the `PNode`, but yea i still dont know what's proper since that "this is 32 bytes on 32bit" message scares me 😛
07:26:54saemYeah, same hesitation. But as the saying goes make it work, make it good, then make it fast.
07:28:57saemI think it's fine for now, by the time it's ready for PR I'm guessing it'll have changed a bunch. Seeing a working implementation is the first step.
07:31:44saemThe same idea can improve other inference issues.

11:19:24FromDiscord<haxscramper> https://wandbox.org/permlink/A8QNkqIInsRx05sM to be honest it seems like a bug with current version. devel on wandbox works correctly
11:19:53FromDiscord<haxscramper> Because `TripleKindType` is a typeclass, so your implementation should not fail the way it does not
11:19:55FromDiscord<haxscramper> (edit) "not" => "now"
11:20:32FromDiscord<haxscramper> The only thing that was wrong in your -`test(1, "name", "Bob")` instead of a `test (1, "name", "Bob")`
11:20:48FromDiscord<haxscramper> First one calls `test` with three arguments, second calls with one tuple argument
11:21:01FromDiscord<zidsal> oops, I forgot the brackets when I made my noddy example
11:21:18FromDiscord<haxscramper> But that has nothing to do with your error

19:52:39FromDiscord<ElegantBeef> !eval echo cast[string](cast[seq[byte]]("Hello"))
19:52:41NimBotHello
19:53:02FromDiscord<gollark> Isn't cast unsafe?
19:53:12FromDiscord<ElegantBeef> Only unsafe if you dont wear protection
19:53:18FromDiscord<gollark> I see.
19:53:27FromDiscord<ElegantBeef> unsafe doesnt mean dont use it, it means dont use it unless you know what you're doing
19:53:58FromDiscord<ElegantBeef> I believe in this case it's completely fine since we are staying inside Nim
19:54:04FromDiscord<ElegantBeef> But i could be wrong 😄
19:54:46FromDiscord<treeform> In reply to @gollark "Is it possible (and": I cast string to a seq[byte] all the time. No issues so far.
19:55:13FromDiscord<gollark> I was worried because of the fact that they're apparently null-terminated, and my string isn't necessarily.
19:55:26FromDiscord<gollark> isn't necessarily free of nulls, or null-terminated
19:55:30FromDiscord<ElegantBeef> Unsafe in Nim isnt like in rust, it's not scary dont use stuff, it's "dont touch unless you know you want it"
19:55:33FromDiscord<gollark> the seq
19:55:37FromDiscord<ElegantBeef> Well Nim strings arent Cstrings
19:55:49FromDiscord<ElegantBeef> you can have a string full of `\0`
19:56:01FromDiscord<demotomohiro> string always have terminating zero but that is not count in .len()
19:56:07FromDiscord<ElegantBeef> Yea
19:56:52FromDiscord<ElegantBeef> seq's and strings have the same type layout where it's a pointer to `cap, length, data`
19:57:18FromDiscord<ElegantBeef> So the casting is fine since that extra information is in the data and only used when converted to a cstring
19:57:48FromDiscord<ElegantBeef> And treeform i've toyed with the compiler and bodged in enum inference 😄
19:58:02FromDiscord<ElegantBeef> still have to clean it up, but it works 😛
19:59:57FromDiscord<demotomohiro> Is it possible that binary layout of string or seq will be changed in future and casting them become unsafe?
20:00:12FromDiscord<ElegantBeef> Possibly, stringv2 i think does change the layout
20:00:58FromDiscord<ElegantBeef> Stores the cap and len as the first two values in the data
20:01:08FromDiscord<ElegantBeef> Atleast iirc
20:02:11FromDiscord<ElegantBeef> In that case it's still not difficult to convert
20:04:04FromDiscord<gollark> I have another problem. I need to offload the generation of the image things to another thread, since it's quite slow. It seems that just passing a tableref to `createThread` and having it update that doesn't work, since the table is presumably copied at some point. I looked at channels, but they don't look like they work well with async. What's the best way to do this?
20:04:18FromDiscord<demotomohiro> Then, casting each char to byte one by one seems safter than casting string to seq[byte] (but slower).
20:05:19FromDiscord<ElegantBeef> sent a code paste, see https://play.nim-lang.org/#ix=39aR
20:06:49FromDiscord<gollark> I guess I could make the thing which needs the images poll a channel from the other thread and put them in a table then, but that seems terrible.
20:11:20FromDiscord<ElegantBeef> How is the program flow, does it generate image then send it out, so it only needs a single buffer for the "generating image"?
20:11:48FromDiscord<gollark> Images are generated at intervals and then may be used to respond to lots of HTTP requests.
20:12:55FromDiscord<ElegantBeef> What you could do is make a bunch of images with the data guarded by a lock then only send the data when you can acquire the lock otherwise do whatever you need to do
20:13:17FromDiscord<ElegantBeef> Dont know how that fairs with async so... 😄
20:13:53FromDiscord<gollark> I may just do the somewhat horrible channel thing then.
20:14:22FromDiscord<ElegantBeef> I dont do async or threading much so i'm the worst person to talk here
20:19:48FromDiscord<demotomohiro> createShared proc in system module might be able to create a object shared between threads↵https://nim-lang.org/docs/system.html#createShared,typedesc
20:20:13FromDiscord<demotomohiro> but I never used it.
20:22:21FromDiscord<gollark> IIRC this has issues if the shared thing contains further GCed things.
20:23:00FromDiscord<ElegantBeef> Afaik with orc/arc since they have a shared heap you can just turn off thread analysis and do stuff that you know is safe

20:39:21giacosure, but that cleans up the repo, but not the project folder. My vscode workspace looks just messy with all the binaries
20:54:19FromDiscord<ajusa> is there any way for me to create a table that maps to multiple different types? Specifically, I'm trying to do something like↵`var sorts = initTable[string, seq[any_type]]`.
20:55:35FromDiscord<ElegantBeef> You'd need to box the types using an object variant
20:56:06FromDiscord<zidsal> sent a code paste, see https://play.nim-lang.org/#ix=39ja
20:58:43FromDiscord<ElegantBeef> @ajusa something like this https://play.nim-lang.org/#ix=39jz
21:00:12FromDiscord<ElegantBeef> If the page looks dead, refresh until it's not
21:00:27FromDiscord<zidsal> it worries me how quickly you bash our these examples @ElegantBeef
21:00:36FromDiscord<ajusa> In reply to @ElegantBeef "<@!102899813149855744> something like this": Hm, that doesn't quite work for my use case it seems like. I know my table will map from string to a sequence of some type, but I don't know what type that is necessarily.
21:01:12FromDiscord<zidsal> will every type in the table map to the same value?
21:01:21FromDiscord<ElegantBeef> Well if the type cannot be statically known you might have an issue in a static language 😛
21:01:38FromDiscord<zidsal> same type
21:01:46FromDiscord<ajusa> In reply to @ElegantBeef "Well if the type": Yeah lol, that's the answer I was expecting to be honest. Wasn't sure if what I was asking was even feasible.
21:01:55FromDiscord<ElegantBeef> Well you can box a lot of values
21:02:07FromDiscord<ElegantBeef> But it's statically typed so you have to be able to statically represent it
21:02:11FromDiscord<zidsal> or make it take generics of a box type?
21:02:22FromDiscord<zidsal> so the box time can be defined later
21:03:21FromDiscord<ElegantBeef> Zidsal i make too many examples for some things i should just bookmark it and add commands to nimbot 😄
21:03:59FromDiscord<ajusa> Well, here's my use case outlined:↵I'm working on a wrapper for a dragging/reordering library (js) for Karax. I would like the API to work by having users pass in an id (string), and a some sequence of any type. Then, when someone drags and drops something, I can look up the original sequence (using the table), and swap/move values as needed in the sequence.
21:04:06FromDiscord<zidsal> or... we put all your examples into a markov chain and hope it generates an example that a. compiles b. answers the questions
21:04:39FromDiscord<ElegantBeef> Well if this is js you can just use the `jsffi` and `JsObject` then dont have to worry about typeps
21:04:44FromDiscord<zidsal> sent a code paste, see https://play.nim-lang.org/#ix=
21:04:44FromDiscord<ElegantBeef> (edit) "typeps" => "types"
21:04:50FromDiscord<ElegantBeef> Well a JsObject
21:04:55FromDiscord<zidsal> or am I mis understanding
21:05:20FromDiscord<ElegantBeef> And a JsObject works like a jsonnode so you can always just use that ;P
21:05:21FromDiscord<ajusa> I was mimicking the way the VueJS bindings to this library work, where you basically give it a type to iterate over, and fill in a callback that has the index/item defined for each iteration
21:05:51FromDiscord<ElegantBeef> Take inspiration for the json node 😛 https://nim-lang.org/docs/json.html#JsonNodeObj
21:06:05FromDiscord<ElegantBeef> Anyway dog's need walked, so best not need any examples!
21:06:13FromDiscord<zidsal> how do macro's work with js frontend? this could potentally work with a cachemap
21:06:16FromDiscord<zidsal> and generics
21:06:16FromDiscord<ajusa> In reply to @ElegantBeef "And a JsObject works": Yeah, JsObject might make the most sense for me here (since this code doesn't make sense to be ran on the C target)
21:06:31FromDiscord<ElegantBeef> Macros generate code the exact same
21:06:44FromDiscord<ElegantBeef> We already have jsobject to emulate the js object
21:06:52FromDiscord<ElegantBeef> You can use arbitrary fields to add to it
21:07:12FromDiscord<ElegantBeef> https://nim-lang.org/docs/jsffi.html#%5B%5D%3D%2CJsObject%2Ccstring%2CT
21:08:08FromDiscord<ajusa> Yep, so my guess is that the user just casts their `seq[my_type]` to `seq[JsObject]` before passing it into my function to add it to a global table. I'll try that and hopefully it works!
21:14:45FromDiscord<ajusa> hm, since I need to modify the seq this doesn't work as the output of cast is always immutable? So I try doing seq.add and seq.remove in my proc and I get↵` but expression 'things = cast[seq[JsObject]](rootTask.children)' is immutable, not 'var'`

21:28:01FromDiscord<ajusa> hm, mapping from a string to a var seq doesn't seem to work, I think that the seq is getting copied somewhere somehow? After indexing into my table, getting the seq, and modifying it the original is unchanged

21:40:01FromDiscord<ajusa> seems like I need to use refs everywhere for this to work? Like passing a sequence by reference using the `ref` keyword explicitly if I want to be able to modify it from the table, rather than using `var`
21:46:55FromDiscord<ElegantBeef> @ajusa you may want to check `withValuee`
21:46:56FromDiscord<ElegantBeef> (edit) "`withValuee`" => "`withValue`"
21:49:20FromDiscord<ajusa> In reply to @ElegantBeef "<@!102899813149855744> you may want": I'm not sure if that is my problem though, as I am trying to reference something in my table that was assigned using the var type. I'll try it out though
21:49:42FromDiscord<ElegantBeef> Oh well yea it copies or sinks the value from the seq
21:49:57FromDiscord<ElegantBeef> you want it to be `ref seq[T]` if you want it to propagate backwards
21:50:02FromDiscord<ajusa> I had a minimal example, clicked publish, and then https://play.nim-lang.org/ failed lol

22:13:15FromDiscord<ElegantBeef> Saem no idea if you're about but yea i now see what you mean about more intelligent inference, cause i can now solve `var t: array[4, Enum] = [valA, valB, valC, valD]` even if there is ambiguity
22:13:27FromDiscord<ElegantBeef> Which can even be extended to bytes and the like
22:13:32saemcongrats!
22:13:34saemthat's awesome
22:22:06FromDiscord<ElegantBeef> Thought it seems like the non enum values are more complex to remedy
22:22:43giacois there a better way to get the fractional part of a float than "f - f.trunc"?
22:24:38FromDiscord<ElegantBeef> There is split decimal but it probably does something similar

22:52:42reversem3thanks , I'm just teaching my self how to parse out hacker news and hopefully build a gui for it
23:03:20giacoI'm writing a testcase for a proc that returns a float, but rounding to decimal place is not reliable (https://nim-lang.org/docs/math.html#round%2CT%2Cint) and equal operator on floats like 8.413800000001 smells like the wrong thing to do. How would you test this?
23:04:34FromDiscord<ElegantBeef> Convert to a string is my view
23:04:43giacok
23:04:45FromDiscord<ElegantBeef> So you can remove decimals and then compare those two

23:34:05giacoI've "type MyFloat = float" type with it's own "proc `$`*(f: MyFloat): string = &"{f:0.6f}"", but this makes ambiguous call when I call $ on it. The obvious solution would be to make it distinct float but that makes other function I'm using like trunc and round not working on such type. What's the correct way to borrow float functions into my distinct float?
23:35:26FromDiscord<ElegantBeef> This part of the manual explains it all https://nim-lang.org/docs/manual.html#types-distinct-type
23:35:30FromDiscord<ElegantBeef> `{.borrow.}`
