01:05:45FromGitter<Varriount> If I can actually load json at compile time
01:06:32FromGitter<Varriount> The parser in the standard library won't work at compile time, and the one available on Nimble is little more than an event emitter

01:27:21dom96in any case, you might be able to fix the json module for that purpose.

01:48:24FromGitter<Varriount> @dom96 I can't fix it until `when nimvm` is less limited.

02:21:49FromGitter<zacharycarter> @Varriount how do we make ^ happen?
02:26:22FromGitter<ephja> https://github.com/nim-lang/Nim/blob/devel/lib/pure/collections/tableimpl.nim#L123 how should this deal with instantiations where either the key or the value type is annotated with `not nil`? "lib\pure\collections\tableimpl.nim(144, 40) Error: cannot prove 't.data[i]' is not nil"
02:27:41FromGitter<ephja> perhaps the only issue is with shallowCopy
02:29:12FromGitter<ephja> nah of course not. regular assignments fail for the same reason

02:39:47FromGitter<Varriount> @zacharycarter Right now I'm just using jsmn
02:39:59FromGitter<Varriount> It's a pain to use, but at least it works
02:41:01FromGitter<Varriount> `when nimvm` won't work in type definitions
02:41:40FromGitter<ephja> you could do "assert t.data[i] != nil". it's just that authors must test these things by instantiating with `not nil`types, unless it can be checked automatically

12:17:56FromGitter<zacharycarter> @dom96 : yup - I think it's due to c2nim I'll have to fix eventually
12:21:54FromGitter<ephja> @zacharycarter are you sure? did you specify a calling convention?
12:29:11FromGitter<mratsim> Is there a semantic/performance difference between ref array and sequences?
12:29:36FromGitter<mratsim> besides the value vs ref when assigning
12:34:33dom96array cannot be resized
12:35:21*Vladar joined #nim
12:35:32FromGitter<zacharycarter> @ephja I meant the lowercase type names
12:35:45FromGitter<ephja> oh
12:38:14FromGitter<mratsim> Ah yes the fixed size, that’s what I’m looking for. I found a big difference, items and mitems are not implemented for ref arrays

13:01:15FromGitter<ephja> @mratsim the only downside is that it's more verbose

13:05:47FromGitter<zacharycarter> also only 4 draw calls for all that :P
13:06:31FromGitter<ephja> @mratsim but it can be done automatically if necessary. you just need to apply the `experimental` pragma before the point of use, at the top (module) level
13:07:20FromGitter<ephja> but of course, the usual disclaimer regarding experimental features apply. it might very well end up being a core feature though
13:07:30FromGitter<mratsim> It’s fine, I just wanted to initialize the ref array with 0 but I was catched off guard by the absence of mitems
13:12:36FromGitter<ephja> I hope it ends up being a core features, because that will encourage users not to define ref parameters when it isn't necessary
13:19:15FromGitter<mratsim> That’s OO for you, everyone wants to pass ref all around ;)
13:20:22FromGitter<mratsim> I was evaluating shallow copy too for my lib this week, and I found a wealth of request to make shallow-copying by default

20:18:14dom96Does my answer make sense? or am I not understanding coldtea.
20:20:12FromGitter<mratsim> I’ve written 2 versions of a matrix multiplication algorithm. One with pointer arithmetics, one with a mutable offset that I increment (instead of moving a pointer). I would have expected the pointer one to be faster but it’s 2x slower on a Broadwell CPU when multiplying 2 5000x5000 matrices. Is Nim doing (very!) aggressive optimization on array access? ⏎ ⏎ I tried checking the C code but I didn’t find
