From 752c0676e81fed57dd9d4b406cfc5d2b94865820 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 31 Jul 2026 15:18:35 +0000 Subject: [PATCH 01/18] feat(compiler): Direct XAML v0 spec and Rust compiler front-end MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds `compiler/`, a self-contained Rust workspace that compiles a strict subset of WinUI 3 XAML into a backend-neutral UI IR. This is the front-end only — no runtime, no Win2D, no MSBuild wiring, and nothing under `dotnet/` depends on it. The target is `MinimalServiceResultItem.xaml`, the smallest real translation-result card. A verbatim copy is a test fixture, so the suite compiles markup that actually ships. Pipeline: XML CST (spans, error recovery) → XAML AST (namespaces, directives, property elements, markup extensions) → typed HIR (schema-checked, parsed values) → UI IR (JSON, validated). Three findings from the existing code shaped the design: - The app contains **no `x:Bind`** — all 12 XAML files use `x:Name` plus imperative code-behind. So `x:Name` compiles to a *named slot* carrying the properties writable at runtime and what each write invalidates, rather than a binding pipeline. A test pins that set against every property `MinimalServiceResultItem.UpdateUI()` actually writes, so the method ports without being rewritten. - `IServiceResultView` + `ServiceResultViewHost` already swap renderers, so a direct renderer is a third implementation of that interface, not a new parallel abstraction. - `{ThemeResource}` supplies `BorderThickness` and `CornerRadius` on the real card, so resource references are legal for any property type — and compile to runtime slots, never folded values, to keep theme switching working. The compiler is total: every construct is either in the subset or produces an MSBuild-formatted diagnostic. `ServiceResultItem.xaml` is deliberately rejected, and CI fails if it ever starts compiling. `quick-xml` is confined to `dxaml-syntax/src/lexer.rs` — it breaks API across minor versions, so the blast radius of a bump is one file. Spans are computed locally since the library exposes no per-attribute positions. Also adds a `rust.yml` workflow (fmt, clippy -D warnings, test, plus the two end-to-end compile checks) and pins `compiler/target/` in .gitignore.

Nothing is wired into the app yet — this is the layer between the IR and a rendering backend. Deliberately plain net8.0 with no WinUI or Win2D dependency. Everything testable without a Windows desktop lives here: IR loading, slot storage, invalidation, layout, and display-list generation. The backend is reached only through ITextMeasurerFactory and IResourceResolver, mirroring how Polyglot.TextLayout keeps its ITextMeasurer seam. Since none of this C# can be compiled in the authoring environment, that split is what keeps the unverifiable surface down to the executor and the WinUI glue. - Ir/: records mirroring dxir-v0.schema.json, System.Text.Json polymorphic values. The loader refuses unknown ir_version and unknown features outright rather than degrading — the compiler guarantees a total translation, and the loader upholds the other half of that contract. - CompiledView: slot writes carrying the IR's declared invalidation, so a colour change repaints without re-running layout. Rewriting a slot with an unchanged value dirties nothing, which matters because UpdateUI rewrites everything on each notification. Writing a property a slot does not declare throws rather than silently doing nothing. - Layout/: Grid (auto/star/fixed tracks, two-pass so text wraps at the final column width rather than the merely-available one), StackPanel, Border, TextBlock. Line breaking is delegated to Polyglot.TextLayout so CJK kinsoku behaviour matches the rest of the app. - Render/: backend-neutral draw commands. Asymmetric borders are emitted as per-edge fills, which is what makes the header's BorderThickness="0,0,0,1" come out right; only a uniform stroke with a corner radius uses a single stroked rounded rectangle. Also adds the Easydict.DirectXaml.Win2D project file — a placeholder whose build doubles as the Win2D x WindowsAppSDK 2.0.* compatibility check, which has never been verified. Win2D is referenced nowhere else in the solution. Fixes the rust.yml trigger: it only fired on master, so the workflow added specifically to verify blind-written Rust had never run once. Feature branches are now included.

which ends an `r#"..."#` literal early. Doubled hashes fix it. Worth recording what the run that caught this proved: clippy checked dxaml-syntax, dxaml-schema, dxaml-ast and dxaml-hir clean, so the quick-xml usage and the whole parse -> AST -> HIR chain compile. dxaml-ir was the only crate that failed, on this one literal.

Off by default behind SettingsService.DirectRenderer. Win2D backend (Easydict.DirectXaml.Win2D), the only place Win2D is called: - Win2DTextMeasurer supplies Polyglot.TextLayout with DirectWrite metrics. Both the text formats and the measured widths are cached: Polyglot asks per segment and per grapheme, so an uncached measurer would build a CanvasTextLayout thousands of times per paragraph and give back more than the direct renderer saves. - DisplayListExecutor replays draw commands. Clips and opacity groups both map onto Win2D layers, so one stack serves both, unwound in a finally block. - DirectXamlCanvas hosts the CanvasControl: rebuilds device resources on CreateResources (which also fires after a lost device), lays out on width change, and never mutates layout synchronously from inside a draw pass — a stale height is queued onto the dispatcher instead. Pointer handling walks from the hit leaf up through its ancestors, because the card declares PointerPressed on the header Border while the pointer lands on the text inside it. Without that walk the header would simply stop responding. WinUI integration: - DirectServiceResultItem ports MinimalServiceResultItem.UpdateUI line for line, each `X.Property = value` becoming a slot write. It wraps the canvas in a Grid so Element and HeaderPanel stay distinct objects — the host stamps a different AutomationId on each, and UI automation locates cards by ServiceResultItem_, which a shared object would clobber. - ThemeResourceResolver forwards resource slots to ThemeResourceService. It resolves Thickness and CornerRadius as well as colours: the card supplies BorderThickness and CornerRadius via {ThemeResource}, so a colour-only resolver would silently flatten its border and corners to zero. - ServiceResultViewHost gains a third branch that falls back to the XAML renderers on any failure, and now disposes renderers that own native resources. - GetMinimalDisplayText became internal so both renderers derive display text from one implementation rather than drifting copies. The IR itself is not checked in yet — it needs dxamlc, which has never compiled. The EmbeddedResource is conditional and IsAvailable reports false without it, so the app keeps using the XAML renderers until the IR lands. Tests (net8.0, no Category traits so ci.yml actually runs them) cover IR loading and its refusals, slot invalidation including the no-op case, exact layout geometry via a fixed-advance measurer, and display-list output — notably that BorderThickness="0,0,0,1" comes out as one edge fill rather than a four-sided stroke. Adding the projects to the solution makes ci.yml build Easydict.DirectXaml.Win2D on every push, which is the Win2D x WindowsAppSDK 2.0.* compatibility check.

Two things that run settled: Win2D is compatible with WindowsAppSDK 2.0.*. Microsoft.Graphics.Win2D resolved to 1.4.0 and Easydict.DirectXaml.Win2D compiled, so the executor does not need one of the fallback backends. It does emit WIN2D0001 because the solution builds that project as AnyCPU; the reference still resolved, and publish always passes --runtime win-x64, so this is left as a warning rather than churning the solution's platform mappings to chase it. The redundant self-import of the root namespace goes too — the test namespace already nests inside it.

The real card sets TextWrapping="Wrap" on ResultText, so the fixture now matches it. Text in the other layout assertions is short enough that wrapping does not change their geometry.

Only the trigger addition is kept, which has already paid for itself. That leaves the original zero-match failure, which this branch did not cause and which needs a decision about shared CI rather than another attempt from me. None of this touches the renderer.
