Hi, I started looking into implementing comp shaders for Windows and hit a few errors with the shaders that I'm not sure how to solve.

error X3663: thread sync operation found in varying flow control, consider reformulating your algorithm so all threads will hit the sync simultaneously:

backdrop.comp (and few others):

void main() {
    if (mem_error != NO_ERROR) { // <---
        return;
    }
    ...
    barrier(); // <---

error X3000: syntax error: unexpected token 'vector':

struct TileSeg {
    vec2 origin;
    vec2 vector; // <--- it looks like "vector" is a reserved word.
    float y_edge;
    TileSegRef next;

generate: Z:\Temp\shader-convert292189591\kernel4.comp(1000,17-25): error X3708: continue cannot be used in a switch

case Cmd_Jump:
    cmd_ref = CmdRef(Cmd_Jump_read(cmd_alloc, cmd_ref).new_ref);
    cmd_alloc.offset = cmd_ref.offset;
    continue; // <---

error X4026: thread sync operation must be in non-varying flow control, due to a potential race condition this sync is illegal, consider adding a sync after reading any values controlling shader execution at this point

MallocResult alloc_clip_buf(uint link) {
    if (gl_LocalInvocationID.x == 0 && gl_LocalInvocationID.y == 0) {
        MallocResult m = malloc(CLIP_BUF_SIZE * 4);
        if (!m.failed) {
            write_mem(m.alloc, (m.alloc.offset >> 2) + CLIP_LINK_OFFSET, link);
        }
        sh_clip_alloc = m;
    }
    barrier(); // <---
    return sh_clip_alloc;
}

Currently adds three different variants Contain, Cover, ScaleDown and Fill. These behave similarly to object-fit.

This can be combined with other layouts. A common example could be:

return layout.Center.Layout(gtx, func(gtx layout.Context) layout.Dimensions {
	return layout.Cover.Layout(gtx, image.Layout)
})

Golint issues:

app/internal/window/os_wayland.go:1448:12: gioui.org/io/system.StageEvent composite literal uses unkeyed fields
app/internal/window/os_x11.go:183:12: gioui.org/io/system.StageEvent composite literal uses unkeyed fields

Goimports command:

find gio/ -type f -name '*.go' | xargs -I '{}' goimports -w '{}'

Note: This PR is intended to assess the Gio Sourcehut/GitHub integration. It contains no functional code changes, only stylistic.

Preferably, Gio would be able to employ similar collaboration synchronization tools as those employed by the official Go project, which would enable automatically creating Sourcehut patches for corresponding GitHub PRs made to the Gio mirror repository.

Thusly, consider this PR not as a suggestion for code change to Gio, it may very well be ignored and closed. Consider it instead a test of the integration bridge between the Sourcehut Gio repository and the GitHub Gio mirror repository.

Cheers, Robin

Before this change, Gio could spawn multiple w.requestAnimationFrame.Invoke, which generates multiples w.draw, faster than the monitor refresh-rate.

This patch aims to call w.requestAnimationFrame.Invoke everyframe, but it will only draw (w.draw) when animating.

Currently building Gio apps on Wayland will show status bar Unknown window as active.

This pr adds appID = "" default: filepath.Base(os.Args[0]) resulting Gio apps to show with that default appID using -X gioui.org/app.appID=org.gioui.app will result

By creating simple .desktop entry ~/.local/share/applications/org.gioui.app.desktop

[Desktop Entry]
Version=1.0
Encoding=UTF-8
Type=Application
Name=Gio
GenericName=Gio application
Exec=gio %F
Terminal=false

this would allow setting it also with -X gioui.org/app.appID=%s from gioui/gio-cmd since it would be fine to share -appid flag i guess.

New "ViewController" field on ViewEvent, which contain UIViewController for iOS. That is necessary to open custom UIViewController on top of Gio.

In the beginning of each frame, multiple calls to GetInteger/GetFloat is performed, taking around ~2ms out of ~8ms.

Now, those data are cache at first usage, avoiding calls to JS. It saves around ~2ms out of ~8ms.

Due to syscall/js usage of TextEncoder, which is slow on Chrome, a new cache was created, to bind function and use Invoke instead. It saves around ~1ms out of ~8ms.

In total, this patch improves the performance from ~8ms to ~5ms. It still slower than https://github.com/gioui/gio/pull/4.

Previously, the Inset could be report wrongly when the bottom inset is smaller than the top. Now, it uses image.Rectangle directly, to bypass image.Rect checks.

On Windows, it's required to SetFocus to receive keyboard events. Previously, Gio doesn't set focus on the current window. In some edge cases, it prevents Gio from getting keyboard events.

That is more noticeable when spawning children's windows or parent windows. In such a case, the child window can steal keyboard focus, and Gio will never recover it. Now, it will retrieve the focus when using key.FocusOp.

That change makes possible to provide custom PKCS#12/JavaKeystore using -key and the password with -pass. Also, it's possible to use PKCS#8 key along with X509 certificate, using -key and -cert.

By default the gogio will use the debug.keystore, if no key is provided.

Use DWM to disable the title bar, so that the window has the default window style, support windows 11 fast layout arrangement

Directional navigation with arrow keys/dpad was only enabled on mobile targets (Android, iOS) with no way to enable it for desktop.

This change adds a new Option for it, which is useful for game UIs and other apps that allow faster keyboard navigation.

Add non-portable key code to the key.Event type. This allows users to handle platform-specific key codes in the application code. Backends will now always generate input events, even for keys with no well-known names. Previously backends only generated events for keys they recognized.
