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).
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
