yeah use ComPtr.Handle, but maybe we should add an implicit cast to bool 🤔

yeah use ComPtr.Handle, but maybe we should add an implicit cast to bool

MasterMan•4/8/23, 4:24 PM

That works, yeah
Though cast would help, since currently the check requires an unsafe block

PPerksey yeah use ComPtr.Handle, but maybe we should add an implicit cast to bool 🤔

khitiara•4/8/23, 4:25 PM

better yet you can override the true and false operators

PerkseyOP•4/8/23, 4:25 PM

what

PerkseyOP•4/8/23, 4:25 PM

this scares me

khitiara•4/8/23, 4:25 PM

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/true-false-operators

true and false operators - treat objects as Boolean values

Learn about the C#

true

true

and

false

false

operators. Overload these operators to treat your type as a Boolean value

PerkseyOP•4/8/23, 4:26 PM

WHY IS THIS A THNG SWEET JESUS

khitiara•4/8/23, 4:26 PM

maybe also unary ! operator too idk

PerkseyOP•4/8/23, 4:26 PM

so if the implementation is crap you could actually have

(thing && !thing) == true

(thing && !thing) == true

khitiara•4/8/23, 4:27 PM

yes

PPerksey WHY IS THIS A THNG SWEET JESUS

khitiara•4/8/23, 4:27 PM

this is the appropriate reaction imo lol

khitiara•4/8/23, 4:27 PM

idk where i learned about this cursed stuff but there ya go

Howie•4/8/23, 4:28 PM

double barrel foot gun there!

khitiara•4/8/23, 4:28 PM

as for why its a thing probably something to do with implicit casts and stuff like the ?: operator not working nicely, idk

khitiara•4/8/23, 4:29 PM

that thing has been in the spec since at least 2011 probs earlier

MasterMan•4/8/23, 4:34 PM

Either override the ! operator, or add an "IsValid" function, or both

khitiara•4/8/23, 4:35 PM

the real answer is to just add an IsValid property yeah

PerkseyOP•4/8/23, 4:35 PM

yeah i think so too

PerkseyOP•4/8/23, 4:58 PM

though cursed "dylan's 3.0 headcannon" fact: I am currently thinking of adding a

NullPtr

NullPtr

type that can be used to check all this. basically i want 3.0 (in my head, this isn't official yet) to be super seamless to interact with from C# but there's just some things we can't do in the language, so silk.net.core would contain a mini DSL that makes working with unsafe better

PerkseyOP•4/8/23, 4:58 PM

i.e. you could do

var x = (int*)1;
Ptr<int> y = (int*)2;
var z = new ComPtr<IUnknown>((IUnknown*)3);
Console.WriteLine(x == nullptr);
Console.WriteLine(y == nullptr);
Console.WriteLine(z == nullptr);

var x = (int*)1;
Ptr<int> y = (int*)2;
var z = new ComPtr<IUnknown>((IUnknown*)3);
Console.WriteLine(x == nullptr);
Console.WriteLine(y == nullptr);
Console.WriteLine(z == nullptr);

khitiara•4/8/23, 4:59 PM

not a bad idea tbh

PerkseyOP•4/8/23, 5:02 PM

basically they made a massive mistake making

global using static Silk.NET.Core.DSL.SilkDSL;

global using static Silk.NET.Core.DSL.SilkDSL;

possible

PerkseyOP•4/8/23, 5:02 PM

because unless the user turns it off, we can decorate the C# language with a bunch of new """keywords""" that are tailored to unsafe uses

PPerksey here's a cursed prototype i came up with just now <https://sharplab.io/#v2:CYLg1...

TechPizza•4/8/23, 7:01 PM

oh no, a static readonly instead of a static property when

TechPizza•4/8/23, 7:01 PM

i actually ported msvc std source to c# with a

Ref<T>

Ref<T>

helper lol

TechPizza•4/8/23, 7:02 PM

it was basically a

ref

ref

that acted as a pointer

TTechPizza i actually ported msvc std source to c# with a `Ref<T>` helper lol

PerkseyOP•4/8/23, 7:18 PM

Yeah this is basically what I’m thinking, but I just need to figure out how we can have a Ref-like struct in a non-ref struct

PerkseyOP•4/8/23, 7:19 PM

otherwise you can’t have Ptr<VkBaseOutStructure> and other common patterns

FFurball dxvk exists but idk if the developer experience on linux would be great

Lyris the Kitori•4/8/23, 8:17 PM

you have access to renderdoc and a debugger, so it's really workable

PPerksey you awoken the era of graphics i've been trying to pretend doesn't exist 😂

if you think about it FFP is better than modern OpenGL as it has display lists

Lyris the Kitori•4/8/23, 9:13 PM

so its basically vulkan with command lists

PerkseyOP•4/8/23, 9:13 PM

NO BAD

PPerksey NO BAD

Lyris the Kitori•4/8/23, 9:13 PM

OKAY BUT DISPLAY LISTS IN MODERN OPENGL WOULD BE SO NICE

Lyris the Kitori•4/8/23, 9:13 PM

i know theres nv_command_list but its nv only

Lyris the Kitori•4/8/23, 9:14 PM

FFP OpenGL does have SOME things going for it

Lyris the Kitori•4/8/23, 9:14 PM

the ability to disconnect recording draw commands from execution is something that OpenGL should have kept

TechPizza•4/8/23, 9:14 PM

funnily enough, recorded display lists on nvidia in legacygl seem pretty good

TechPizza•4/8/23, 9:15 PM

the only problem is that conditional rendering is a no-go

Lyris the Kitori•4/8/23, 9:15 PM

yeah on my ol 1050ti my FFP code was shockingly fast

Lyris the Kitori•4/8/23, 9:15 PM

it was 10x slower

Lyris the Kitori•4/8/23, 9:15 PM

but

Lyris the Kitori•4/8/23, 9:15 PM

thats still

Lyris the Kitori•4/8/23, 9:15 PM

really fast

yeah use ComPtr.Handle, but maybe we should add an implicit cast to bool 🤔
