darwin breakage on gio-windowing about go-webgpu HOT 8 CLOSED

i reopened it. Hope you do not mind..

from go-webgpu.

I dont know how to do the Cocoa handles. am mostly pure golang developer
I know that in the GIOUI code base they recently had work done for Platform Views, which is slightly related.

wish i could be more help.

The triangle example works on Mac still... so might be gio related.

apple@x-MacBook-Pro-2 triangle % go build .
apple@x-MacBook-Pro-2 triangle % ls
main.go				surface_android.go		surface_wayland_linux.go	surface_x11_linux.go
shader.wgsl			surface_darwin.go		surface_windows.go		triangle
apple@x-MacBook-Pro-2 triangle % ./triangle

sorry i just noticed that darwin is not implemented yet: https://github.com/rajveermalviya/go-webgpu/blob/main/examples/gio-windowing/surface_darwin.go#L11

from go-webgpu.

i just pulled latest.

Now for gio-windowing example i get:
./main.go:70:34: undefined: getSurfaceDescriptor

Much less errors.

yep, it's because gio-windowing example currently lacks support for darwin. I mainly have it in just to showcase android support.
you should instead be able to run glfw-based examples (triangle, cube, boids) on darwin.

would really appreciate if someone with a mac is willing to shoot a PR.
I haven't looked into how gio exposes Cocoa handles, doubt it would be much different than how glfw does it.

from go-webgpu.

while implementing it (see #199) it seems this is not possible with Gio's current api.

Gio's current api prevents using it as a standalone windowing library (atleast for macos & i assume ios too),
because the metal layer provided by ViewEvent cannot be resized
from a separate goroutine (non main thread).

we can merge #199 as is, but that would not be good idea as resizing the window will fail.

from go-webgpu.

the latest GIO should help and you can also use it as standalone.

https://github.com/gioui/gio-example/blob/main/glfw is a simple example doing it which might help ?
