From cf749735dc452b53c25bdb62aa48c5cde362b59c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ralph=20K=C3=BCpper?= Date: Mon, 22 Jun 2026 05:35:55 +0200 Subject: [PATCH 1/3] feat(attach): host-surface attach path on all platforms (PerryTS/perry#5519) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a per-platform "attach to a host-provided surface" entry point so a BloomView (Perry UI) can hand the engine a native view/window/surface it already owns, instead of the engine creating its own window. Previously only Windows could embed (via the engine#70 bloom_attach_hwnd work); every other target created a view but no renderer attached to it. Engine - native/shared/src/attach.rs: factor the wgpu bring-up — instance → surface → adapter → device → swapchain → Renderer → EngineState — duplicated in every platform's bloom_init_window into one attach_engine() helper, parameterised by backend bitmask, dimensions (logical + physical for HiDPI), and a FormatPreference (Srgb / NonSrgb / First) covering each platform's swapchain-format policy. Returns a Result instead of panicking so a host attaching to a not-yet-realized view can recover. - One unified ABI symbol bloom_attach_native(handle, w, h) -> f64 rather than distinct per-platform names: the function manifest is shared and validate-ffi requires every platform to export every entry, so a single symbol (each platform interpreting `handle` as its own view/window/surface pointer) is cleaner than N stubs. TS exposes the named wrappers attachToNSView / attachToUIView / attachToSurface + attachToNativeView, all forwarding to it. - macOS: bloom_init_window refactored to use attach_engine (proves the factoring) + real bloom_attach_native on a host NSView. - iOS / tvOS / visionOS: real attach on a host UIView (tvOS/visionOS use a non-sRGB swapchain to match their windowed path). - Android: real attach on a host ANativeWindow. - Windows: real attach on a host HWND. - Linux: documented stub returning 0 — GTK4 GtkWidget→GdkSurface bridging is the larger follow-up the issue calls out. - watchOS: regenerated no-op stub (no wgpu). web: wasm_bindgen no-op (web builds its surface from the canvas id). - package.json manifest entry; validate-ffi passes 0/0 across all 8 platforms. Verification - shared compiles (native + wasm32); macОS builds and renders a scene end-to-end headless (getScreenWidth/Height read back 320x240 from the attached EngineState, 30 frames, clean exit); iOS cross-compiles; web wasm32 checks. Android/Linux/Windows cross-builds blocked locally by missing C cross-toolchains (NDK / linux-gcc / MSVC), not by this code. --- native/android/src/lib.rs | 56 +++++++ native/ios/src/lib.rs | 50 ++++++ native/linux/src/lib.rs | 17 +++ native/macos/src/lib.rs | 262 +++++++++++++++----------------- native/shared/src/attach.rs | 222 +++++++++++++++++++++++++++ native/shared/src/lib.rs | 5 + native/tvos/src/lib.rs | 47 ++++++ native/visionos/src/lib.rs | 47 ++++++ native/watchos/src/ffi_stubs.rs | 3 + native/web/src/lib.rs | 10 ++ native/windows/src/lib.rs | 59 +++++++ package.json | 9 ++ src/core/index.ts | 39 +++++ 13 files changed, 684 insertions(+), 142 deletions(-) create mode 100644 native/shared/src/attach.rs diff --git a/native/android/src/lib.rs b/native/android/src/lib.rs index 48f3524..452975c 100644 --- a/native/android/src/lib.rs +++ b/native/android/src/lib.rs @@ -262,6 +262,62 @@ pub extern "C" fn bloom_init_window(width: f64, height: f64, title_ptr: *const u } } +/// Attach the engine to a host-owned `ANativeWindow*` instead of pulling +/// it from the global set by `bloom_android_set_native_window` +/// (PerryTS/perry#5519). `handle` is the `ANativeWindow*` the host +/// (Perry UI's `BloomView`, backed by a `SurfaceView`/`TextureView`) +/// owns; `width`/`height` are the surface size in physical pixels. +/// Returns 1.0 on success, 0.0 on a null/invalid handle or surface +/// bring-up failure.

The manifest contract requires every platform to export every entry, so the attach PR can't go green without closing them. - bloom_resize: real on macOS/iOS/tvOS/visionOS/Android/Linux — it just forwards to the shared Renderer::resize (same body as the Windows impl from #70), so host-driven BloomView resizing now works on every target, not only Windows. - bloom_attach_hwnd: no-op stub on the non-Windows native platforms (it's HWND-specific; those hosts use bloom_attach_native). Mirrors #70's own cfg(not(windows)) no-op. - watchos: regenerated ffi_stubs.rs covers the new entries. - web: documented the genuinely-unimplemented entries in tools/validate-ffi.js WEB_GAP_ALLOWLIST (pointer-taking mesh scratch = same WASM linear-memory TODO as bloom_scene_set_lod; post-FX controls not yet wired in the web crate; attach_hwnd N/A on canvas). validate-ffi now passes 0 failures / 0 warnings across all 8 platforms. macOS rebuilds + renders a scene end-to-end; iOS cross-compiles. --- native/android/src/lib.rs | 14 ++++++++++++++ native/ios/src/lib.rs | 14 ++++++++++++++ native/linux/src/lib.rs | 14 ++++++++++++++ native/macos/src/lib.rs | 14 ++++++++++++++ native/tvos/src/lib.rs | 14 ++++++++++++++ native/visionos/src/lib.rs | 14 ++++++++++++++ native/watchos/src/ffi_stubs.rs | 21 +++++++++++++++++++++ tools/validate-ffi.js | 14 ++++++++++++++ 8 files changed, 119 insertions(+) diff --git a/native/android/src/lib.rs b/native/android/src/lib.rs index 452975c..151c605 100644 --- a/native/android/src/lib.rs +++ b/native/android/src/lib.rs @@ -318,6 +318,20 @@ pub extern "C" fn bloom_attach_native(handle: i64, width: f64, height: f64) -> f } } +/// Resize the engine's surface (#70 parity; used by host-driven +/// BloomViews on layout changes). `phys_*` physical px, `log_*` logical. +#[no_mangle] +pub extern "C" fn bloom_resize(phys_w: f64, phys_h: f64, log_w: f64, log_h: f64) { + if let Some(eng) = unsafe { ENGINE.get_mut() } { + eng.renderer.resize(phys_w as u32, phys_h as u32, log_w as u32, log_h as u32); + } +} + +/// HWND host-embed (#70) — Windows only; a no-op here for FFI-manifest +/// parity.
