Content is now normalised to LF (bare `\r` old-Mac endings also handled) before splitting. +- **Virtualized Markdown/Delta sections orphaned headings** (`hyper_viewer.dart`): `_splitIntoSections` (Markdown/Quill Delta virtualized/paged path) lacked the heading-widow guard that `HtmlAdapter.parseToSections` already had. A heading that pushed `currentSize ≥ chunkSize` became the last element of a section, stranding its content at the top of the next section without a heading. Added twin guards: (1) never end a section on `h1`–`h6`, (2) never split immediately before a heading. +- **`Paint()` allocated every frame for filter/backdrop-filter decorations** (`render_hyper_box_paint.dart`): `_paintBlockDecorations` / `_paintInlineDecorations` created inline `Paint()` objects for CSS `filter` and `backdrop-filter` on every paint call. Added reusable `_filterPaint` instance field (same pattern as `_fillPaint` / `_strokePaint`). +- **`_effectiveConfig` dropped `useMicrotaskParsing` and blocked `allowedCustomSchemes`** (`hyper_viewer.dart`): When HTML contained CSS animations, `_effectiveConfig` rebuilt `HyperRenderConfig` but omitted `useMicrotaskParsing` (reset to `false`, breaking widget tests for animated HTML) and did not merge `allowedCustomSchemes` into `extraLinkSchemes` (custom-scheme deep-links silently blocked at the render layer). Both fields now correctly propagated. +- **`allowedTags` diff used reference equality** (`hyper_viewer.dart`): `didUpdateWidget` compared `oldWidget.allowedTags != widget.allowedTags` which is always `true` for new list literals — causing unnecessary re-parses on every rebuild. Now uses `listEquals` for content equality. +- **Incremental layout hash collision on duplicate sections** (`hyper_viewer.dart`): `_mergeSections` used `Map` keyed by 32-bit hash; two sections with identical text share the same hash, so the second overwrote the first and both received the same cached node. Changed to `Map>` with queue semantics. +- **`sanitize` doc-comment stated wrong default** (`hyper_viewer.dart`): Comment claimed default was `false`; actual default is `true`. Corrected with accurate security guidance. +- **`addPostFrameCallback` fired on every `build()` in paged mode** (`hyper_viewer.dart`): `_buildPagedContent` registered `pageController._onSectionsReady` unconditionally each build. Now guarded by `_lastNotifiedPageCount` — fires only when section count changes. + +## [1.2.3] - 2026-04-30 + +### 🚀 Performance & Stability + +- **Test Coverage Optimization**: Increased global test coverage to >75% with new comprehensive suites for parsers, adapters, and selection logic. +- **Golden Test Alignment**: Updated golden tests for consistent multi-platform rendering validation. +- **Improved Widget Test Robustness**: Updated `find.byType(HyperRenderWidget)` assertions to handle multiple instances in the tree caused by virtualization and float nesting. + +### 🐛 Bug Fixes + +- **Fixed `HyperRenderWidget` compilation error**: Resolved a signature mismatch in recursive widget construction where `codeHighlighter` was passed outside of `config` and `pluginRegistry` was missing. +- **Fixed Float Layout logic**: Explicit CSS `width` and `height` properties are now correctly respected for non-image float elements, rather than always falling back to intrinsic text dimensions. +- **Fixed Plugin Propagation**: Ensured `pluginRegistry` is correctly passed to nested renderers, allowing custom tags to work inside floated containers. +- **Missing `foundation` import** in `hyper_viewer.dart`: Fixed compilation error when using `compute` function in some environments. +- **Improved selection logic** for virtualized lists: Fixed edge cases when selecting text across off-screen chunks. +- **Flexible Markdown parsing**: Updated adapter to handle variations in tag output (e.g., `` vs ``) across different environments. + ## [1.2.2] - 2026-04-02 ### 🐛 Bug Fixes diff --git a/CLAUDE.md b/CLAUDE.md new file mode 100644 index 0000000..792bafe --- /dev/null +++ b/CLAUDE.md @@ -0,0 +1,130 @@ +# CLAUDE.md + +This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository. + +## Commands + +### Running tests + +```bash +# Full suite (root + packages, golden tests excluded) +flutter test test/ packages/hyper_render_core/test/ packages/hyper_render_html/test/ --exclude-tags golden + +# Root package only +flutter test test/ --exclude-tags golden + +# Single test file +flutter test test/accessibility_test.dart + +# Single test by name +flutter test test/html_adapter_test.dart --plain-name 'parses links' + +# A sub-package +flutter test packages/hyper_render_core/test/ + +# Golden tests (need --update-goldens first to generate baselines) +flutter test test/golden/ --update-goldens +flutter test test/golden/ + +# Coverage +./scripts/generate_coverage.sh +``` + +### Analysis and linting + +```bash +flutter analyze +dart format --set-exit-if-changed . +``` + +### Publishing + +```bash +# Swap path: deps → version deps, dry-run, then publish +./scripts/prepare_publish.sh +dart pub publish --dry-run +./scripts/publish.sh +``` + +## Architecture + +HyperRender is a **single-RenderObject renderer** — all content is drawn on a single `Canvas` by `RenderHyperBox` rather than building a widget subtree.

In my younger and more vulnerable years my father gave me some advice that I’ve been turning over in my mind ever since.

“Whenever you feel like criticizing any one,” he told me, “just remember that all the people in this world haven’t had the advantages that you’ve had.”

He didn’t say any more, but we’ve always been unusually communicative in a reserved way, and I understood that he meant a great deal more than that. In consequence, I’m inclined to reserve all judgments, a habit that has opened up many curious natures to me and also made me the victim of not a few veteran bores. The abnormal mind is quick to detect and attach itself to this quality when it appears in a normal person, and so it came about that in college I was unjustly accused of being a politician, because I was privy to the secret griefs of wild, unknown men.

Sprint 2: Text Selection & CJK Chaos

+

This document combines Bi-directional text (Arabic), Japanese Kinsoku (line breaking), and Furigana (Ruby) to test the robustness of the Custom RenderBox selection bounds and highlight painting.

+ +

1. Japanese Ruby (Furigana)

+

+ 漢かん + 字じ + の + 読よみ + 方かた + をテストしています。 +

+

Try selecting across the Ruby characters. The blue highlight box should properly cover the base characters and extend upwards to cover the annotation (rt) without clipping.

+ +

2. Kinsoku Shori (Line Breaking)

+

+ これは非常に長い日本語の文章です。行の終わりに句読点が来る場合、それを次の行の先頭に配置することは禁止されています（禁則処理）。「たと えば、このような括弧の開始」が、行の最後に単独で配置されることもありません。 +

+

Select text wrapping around the edge of the grey box. The highlight should wrap perfectly without drawing outside the text boundaries.

+ +

3. Bi-Directional (BiDi) LTR & RTL

+

+ Here is an English sentence containing Arabic text: + مرحبا بك في اختبار التحديد المعقد + which means "Welcome to the complex selection test". +

+

Try dragging the selection handle across the Arabic text. Notice how the visual handle might jump due to logical vs visual ordering of BiDi text. Ensure it doesn't crash.

+ +

4. Cross-Chunk Selection

+

The following blocks repeat to force Virtualization. Start selecting here, and scroll down to select text multiple paragraphs below.

+ \${List.generate( + 50, + (i) => \'\'\' +
