17:12:18om3ga_hi all! I forgot how to dereference for example ptr int
17:13:03om3ga_for example I have ptr to something, created by createShared(int, sizeof(int))
17:13:22om3ga_how to take int and not ptr int, []?

17:20:09*om3ga_ is now known as om3ga
17:21:11om3gaIn my opinion this should work
17:22:01om3gacreate shared is not necessary, both code examples in theory should be ok
17:40:30om3gahmm, probably this will not work in C too
17:55:36om3gayes, in C pthread locks are also defined in global, please ignore

20:32:56FromDiscord<Robyn [She/Her]> Then just check if `presence != null`
20:33:50FromDiscord<System64 ~ Flandre Scarlet> In reply to @chronos.vitaqua "oh wait it's async?": But asyncCheck can throw an exception, and exceptions are quite expansive I think
20:34:07FromDiscord<Robyn [She/Her]> In reply to @sys64 "Lol the double segfault": yeah async dispatch and threads do NOT like eachother
20:34:35FromDiscord<Robyn [She/Her]> In reply to @sys64 "But asyncCheck can throw": await can also throw exceptions, and iirc in arc/orc, try-except are basically just an if statement
20:35:04FromDiscord<System64 ~ Flandre Scarlet> Oh, good to know
20:35:26FromDiscord<Robyn [She/Her]> plus you're using async, isn't most stuff allocated on the heap?
20:35:54FromDiscord<System64 ~ Flandre Scarlet> I think?
20:37:26FromDiscord<Elegantbeef> Async and threads like eachother just fine
20:37:35FromDiscord<Elegantbeef> Futures are just thread local
20:37:43FromDiscord<System64 ~ Flandre Scarlet> In reply to @chronos.vitaqua "oh wait it's async?": so it's↵asyncCheck myFunction()?
20:39:16FromDiscord<Robyn [She/Her]> In reply to @sys64 "so it's asyncCheck myFunction()?": yeah
20:40:08FromDiscord<Robyn [She/Her]> In reply to @Elegantbeef "Async and threads like": you can't spawn an async function on another thread if the future comes from a different thread though, right? that's what i mean
20:40:45FromDiscord<Elegantbeef> Right but that's not what you said
20:41:22FromDiscord<System64 ~ Flandre Scarlet> Isn't using threads just easier?
20:43:29FromDiscord<Elegantbeef> They're two completely different things
20:43:29FromDiscord<Elegantbeef> So no
20:43:29FromDiscord<Elegantbeef> Using selectors is easier
20:44:08FromDiscord<Robyn [She/Her]> In reply to @Elegantbeef "Right but that's not": it captures the meaning sorta :p
20:44:43FromDiscord<Elegantbeef> It reads as you cannot use threads and async at the same time which is false
20:45:15FromDiscord<umi_l> Anyone know of a 3d physics engine for gamedev written in (or has bindings to) nim?
20:49:50FromDiscord<Robyn [She/Her]> In reply to @Elegantbeef "It reads as you": fair enough yeah
20:50:26FromDiscord<Robyn [She/Her]> In reply to @umi_l "Anyone know of a": UE has Nim bindings, there's also Nim bindings for Godot
20:51:06FromDiscord<Elegantbeef> "Physics engine"
20:51:25FromDiscord<umi_l> In reply to @chronos.vitaqua "UE has Nim bindings,": I'm using raylib for my game engine so can't really justify bundling in a whole other game engine, nor would I know how I could do that
20:53:03FromDiscord<System64 ~ Flandre Scarlet> In reply to @chronos.vitaqua "oh wait it's async?": I use an option

23:01:51FromDiscord<dedraiaken> Is there a means of converting a `ptr UncheckedArray[char]` to a string without copying?
23:02:46FromDiscord<Elegantbeef> Nope
23:03:10FromDiscord<Elegantbeef> Nim strings own data so there must be a copy
23:05:47rockcaveradedraiaken https://github.com/rockcavera/nim-zerocstringtostring I was playing around with this once, but I don't know if it's 100% safe.
23:06:11FromDiscord<dedraiaken> hmm so kind of hosed if a library is expecting a string? Shouldn't be able to mimic the data structure and perform a cast?
23:06:15FromDiscord<Elegantbeef> Well it's clearly not safe as you do not own the data
23:06:34FromDiscord<Elegantbeef> Use Nim's string instead then convert to `cstring`
23:06:41FromDiscord<Elegantbeef> Nim strings are null terminated
23:07:26FromDiscord<Elegantbeef> You can abuse the fact Nim strings have a copy on write feature to achieve your no copy, but it's some low level shenanigans that can always change
23:08:12FromDiscord<Elegantbeef> Rock does your implementation abuse the MSB of the capacity(or is it length?) indicating a 'constant'?
23:08:32FromDiscord<dedraiaken> Hmm.. I've got gigabytes of data in a buffer that I want to parse chunks out of as JSON without copying.
23:09:12FromDiscord<Elegantbeef> Well you could abuse that mechanism if you wanted to
23:11:10rockcaveraElegantbeef I don't remember anything about the project, I was just playing around
23:11:42rockcaveraI vaguely remember that I ran valgrind and no problems were reported
23:13:30FromDiscord<Elegantbeef> I looked, you arent
23:13:32FromDiscord<Elegantbeef> Oh it uses the capacity as a flag
23:13:32FromDiscord<Elegantbeef> Which means you need to have an int before the string and say "this is a constant"
23:13:32FromDiscord<Elegantbeef> https://github.com/nim-lang/Nim/blob/devel/lib/system/strs_v2.nim#L26
23:14:02FromDiscord<Elegantbeef> Yea if you're very cautious with your code it's safe
23:14:16FromDiscord<Elegantbeef> But if you attempt to grow the string, or don't call the zero it'll attempt to free the memory
