StyleRun model: array of {start, length, style} with
CharacterStyleOverride (fontWeight, italic, textDecoration, etc.).
Renderer uses ParagraphBuilder.pushStyle/pop for mixed-style text.
TextEditor delegates paragraph building to renderer.buildParagraph().
⌘B/I/U apply to selection range when text is selected, or toggle
whole-node style when no selection. Style runs adjust on
insert/delete to preserve formatting across edits.
Fig roundtrip: import characterStyleIDs + styleOverrideTable from
TextData, export back with deduped style table.
B/I/U/S toggle buttons in TypographySection.
TextEditor class in core — cursor positioning, selection, word
boundaries, line navigation via CanvasKit Paragraph API
(getGlyphPositionAtCoordinate, getRectsForRange).
Renderer draws selection highlights and blinking caret directly
on the canvas. Blue outline around text node during editing.
Phantom textarea captures input, IME composition, clipboard,
arrow keys, Home/End, word/line movement (⌥/⌘ modifiers).
Replaces the old visible <textarea> overlay.
Rust: list_system_fonts and load_system_font Tauri commands using
font-kit crate for cross-platform system font access.
TS: font shim detects Tauri runtime and uses invoke() for font
listing/loading instead of queryLocalFonts (unavailable in WKWebView).
- Column per mode (Name | Mode 1 | Mode 2 | ...)
- Color swatch inside value cells, not next to name
- Search bar in top-right header area
- Single '+ Create variable' button at bottom
- Wider dialog (800px) for multi-mode tables
Three collections with multi-mode support:
- Primitives (Light/Dark): 9 color variables with dark mode values
- Semantic (aliases): Background, Text, Border, Accent, Success, Error
- Spacing (Default/Compact): 8 number variables for space + radius tokens
Binds variables to dashboard sidebar, header, frame, and titles.
Match Figma's pattern: Variables section in page-level properties
panel with settings icon that opens a full dialog (reka-ui Dialog +
Tabs + Editable). Remove sidebar panel approach.
Commands:
- open-pencil info <file> — document stats, node types, fonts
- open-pencil tree <file> — visual node tree with agentfmt
- open-pencil find <file> — search by name/type with rich output
- open-pencil export <file> — render to PNG/JPG/WEBP at any scale
Uses canvaskit-wasm/full for headless CPU rasterization.
All commands support --json for machine-readable output.
agentfmt provides consistent colored terminal formatting.
Move engine (scene-graph, renderer, layout, codec, kiwi) into
packages/core/ as a Bun workspace package. The app's src/engine/
files become thin re-export shims so all existing imports still work.
- Bun workspace with packages/core
- Zero DOM dependencies in core
- Headless-friendly CanvasKit init (locateFile option)
- Constants split: engine constants in core, UI constants in app
- All 76 unit tests pass, lint + typecheck clean, vite build works
renderVersion bumps on every pan/zoom/hover — it's the canvas redraw signal.
sceneVersion only bumps when the scene graph actually changes.
Panels (properties, layers, context menu, pages, export preview) now
depend on sceneVersion, so they don't re-render during navigation.
The default CanvasKit WASM build lacks JPEG/WEBP encoders. Instead of
switching to the full build (+1MB), render PNG via CanvasKit then
re-encode to the target format using OffscreenCanvas.convertToBlob().
Extract renderThumbnail and renderNodesToImage into render-image.ts,
reusing the same offscreen CanvasKit surface approach that fig-export
used for thumbnails.
- ExportSection in properties panel with scale/format selectors,
multi-export support, and live preview with checkerboard background
- Export via context menu and ⇧⌘E shortcut
- Tauri save dialog, File System Access API, and download fallback
- JPG renders with white background, PNG/WEBP with transparency
