* Add multi-provider AI support (Anthropic, OpenAI, Google AI, OpenAI-compatible)
- Add AI_PROVIDERS registry with per-provider model lists, key placeholders, and URLs
- Refactor use-chat composable: provider factory creates the right AI SDK model
- Per-provider API key storage in localStorage with automatic legacy migration
- New ProviderSetup.vue replaces APIKeySetup.vue with provider selector
- New ProviderSettings.vue popover accessible from gear icon in chat input
- OpenAI-compatible provider with custom base URL and model ID fields
- Install @ai-sdk/anthropic and @ai-sdk/google dependencies
- Update E2E tests for new provider setup flow
* Fix reactivity, key masking, missing model ID field, and chat reset on model change
- Use ref instead of computed for apiKey — computed getter over localStorage
wasn't triggering reactivity when the key was set
- Load stored key for new provider in providerId watcher
- Reset chat on modelId and customModelId change, not just provider switch
- Add custom model ID field to ProviderSetup.vue for OpenAI-compatible
- Simplify ProviderSettings key field — empty input with contextual placeholder
instead of fragile dot-masking that broke on partial edits
- Use data-test-id locator for model selector in E2E test
* Use useLocalStorage from vueuse instead of manual ref + watch + localStorage
Replaces 5 hand-rolled ref/watch/localStorage sync pairs with useLocalStorage.
API key uses a computed storage key that rebinds when the provider changes.
* Use useLocalStorage for collab name persistence
* Review fixes: changelog placement, remove dead class, cursor-pointer
* Extract ProviderSelect component and uiInput helper
- ProviderSelect.vue: shared select dropdown for AI providers
- ui/input.ts: shared input styling (sm/md sizes)
- Remove 7 duplicated input class strings across chat components
* Use uppercase acronyms: keyURL, customBaseURL, supportsCustomBaseURL
* Match select dropdown width to trigger via --reka-select-trigger-width
Move min-w-[var(--reka-select-trigger-width)] into selectContent base
style so all selects get it by default. Remove per-component overrides.
* Uppercase acronyms in variable names, improve setup form layout
- providerID, modelID, customModelID, setAPIKey, AIProviderID
- Keep apiKey lowercase at start (standard JS convention)
- Compact setup form: single column, full-width Connect button
- Fix grammar: 'a OpenRouter' → 'an OpenRouter'
- Shorter promo text
* Allow text selection in chat panel
* Fix chat E2E test: Save → Connect button text
* Disable mermaid in chat markdown renderer
Alias mermaid and beautiful-mermaid to empty shims in Vite config,
preventing vue-stream-markdown from attempting to load them.
* Interleave text and tool calls in chat messages
Render message parts in order instead of grouping all tool calls
first then all text. Use SDK's isToolUIPart/isTextUIPart/getToolName
instead of custom type guards. Fix error state: output-error, not error.
* Implement figma.viewport.scrollAndZoomIntoView()
Figma Plugin API method that centers the viewport on given nodes.
Reuses the same bounding box logic as the viewport_zoom_to_fit tool.
* Catch tool execution errors and return them to the AI
Instead of crashing with an unhandled exception, tool errors are
caught and returned as { error: message } so the AI can retry or
explain the failure. UI detects error outputs and shows them in red
with the error message when expanded.
* Replace esbuild with sucrase for JSX transform
Sucrase is a pure JS transform (201 KB / 46 KB gzip) that works in
both Node/Bun and the browser. Replaces esbuild (13 MB WASM) which
only worked in Node/Bun.
- buildComponent() and renderJSX() are now synchronous
- render tool works in browser AI chat (no more 'esbuild required')
- Handles full JS expressions (map, ternaries, Array.from, etc.)
* Update system prompt to prioritize render tool with JSX
Document available tags, props, layout, text, and sizing options.
Instruct the AI to use full JS expressions in JSX for complex layouts.
* Fix zoom shortcuts to match Figma
Cmd+0: Zoom to 100% (was incorrectly mapped to Zoom to fit)
Cmd+1: Zoom to fit
Cmd+2: Zoom to selection
Shift+1 / Shift+2: same as Cmd+1 / Cmd+2
Add zoomTo100() and zoomToSelection() to editor store.
Refactor zoomToFit() to use shared zoomToBounds() helper.
* Refactor keyboard shortcuts to useMagicKeys
Replace manual keydown handler with VueUse useMagicKeys + whenever
for declarative shortcut registration.
- mod() helper for cross-platform Meta/Control shortcuts
- plain() helper for modifier-free keys
- Proper modifier exclusion (⌘G vs ⌘⇧G no longer conflict)
- Add E2E tests: duplicate, zoom (⌘0/⌘1/⌘2/⇧1/⇧2), auto-layout (⇧A)
- All 26 keyboard shortcut tests pass
* Fix scrollAndZoomIntoView to actually zoom
Match Figma Plugin API behavior (equivalent to Shift-1): compute
zoom level that fits all nodes with padding, capped at 100%.
Previously only set center without adjusting zoom.
* Switch to @open-pencil/yoga-layout with CSS Grid support
Use our fork (open-pencil/yoga, grid branch) which cherry-picks the
upstream CSS Grid PRs (#1893–#1898) onto current main. The JS bindings
are ported from the old embind approach to the new wasm_bridge.c API.
npm:@open-pencil/yoga-layout alias keeps all imports as 'yoga-layout'.
Also handle FinalizationRegistry change (upstream #1908) — node.free()
no longer exists, nodes are garbage collected automatically.
* Add CSS Grid layout mode
Scene graph:
- LayoutMode gains 'GRID' option alongside HORIZONTAL/VERTICAL
- GridTrack type (sizing: FIXED/FR/AUTO, value) for track definitions
- GridPosition type (column, row, columnSpan, rowSpan) for children
- New node props: gridTemplateColumns/Rows, gridColumnGap, gridRowGap,
gridPosition
Layout engine:
- buildGridTree() sets Display.Grid and maps GridTrack[] to Yoga's
setGridTemplateColumns/Rows API with FR/Points/Auto track types
- Grid children use gridPosition for column/row placement with span
- Flex layout path unchanged
Store:
- setLayoutMode('GRID') auto-creates NxM track grid based on child
count (sqrt heuristic), defaults to 1fr tracks
UI (LayoutSection.vue):
- Grid button (grid-2x2 icon) added to flow direction row
- Columns/Rows track editors: ScrubInput for value + AppSelect for
sizing mode (Fill fr / Fixed px / Auto), add/remove buttons
- Separate column gap and row gap ScrubInputs
- Wrap button hidden when grid is active
- Flex alignment grid hidden when grid is active
Kiwi serialization skips GRID mode for now (no .fig codec support).
* Add grid layout integration tests
12 new test scenarios covering:
- Basic 2x2 grid, fixed columns, mixed fr/fixed, unequal fr weights
- Column gap, row gap, both gaps combined
- Padding offsets
- Explicit gridPosition placement, column span, row span
- Absolute children skipped
- Hidden children collapsed
- Nested grid inside flex parent (computeAllLayouts)
Also fix: grid frames as children of flex parents now correctly use
Display.Grid via configureChildAsGrid() instead of falling through
to configureChildAsAutoLayout() which set FlexDirection.
* Deduplicate grid yoga configuration
Extract configureAsGrid() and createGridChildNode() shared by
buildGridTree (root-level grid) and configureChildAsGrid (grid
nested inside flex parent).
* Add grid layout to changelog
* Add grid support to JSX and Tailwind CSS export
OpenPencil format: grid → columns/rows/columnGap/rowGap props,
child colStart/rowStart/colSpan/rowSpan.
Tailwind format: grid grid-cols-N grid-rows-N gap-x-* gap-y-*,
mixed tracks use arbitrary values (grid-cols-[200px_1fr_auto]),
child col-start-*/row-start-*/col-span-*/row-span-*.
Both formats: padding emitted for grid frames (shared with flex),
flex-only props (justify/items/wrap/gap) scoped to isFlex.
* Remove duplicate gridTrackToTw, use shared formatTrack
Also drop unused GridTrackSizing import from LayoutSection.vue.
* Fix grid icon: use layout-grid instead of grid-2x2
unplugin-icons can't resolve icon names with digits after hyphens
(grid-2x2 → grid2x2 which doesn't exist).
* Polish layout UI and fix auto-layout behavior
- Replace text labels with compact icons: ↔/↕ for gap, ☐ for uniform padding, T/R/B/L for per-side padding
- Direction-aware gap icon: ↕ for vertical, ↔ for horizontal
- Pin +/− padding toggle button right of gap input
- Fix alignment grid axes for vertical layout (transpose primary/counter)
- Fix grid switch: set FIXED sizing, compute frame size from children
- Remove hardcoded white fill from Shift+A wrap
- Auto-detect horizontal vs vertical from selection bounds
* Add flex-to-grid switch integration test
Verify HUG frame expands and children are placed in 2x2 grid
when switching from vertical flex to grid layout.
* Update changelog for grid layout
bridge.ts is bundled by esbuild as a Vite plugin — it can't resolve
workspace package entries (@open-pencil/core) at config time because
dist/ is not built yet. Use relative import to the source file instead.
- New AppSelect.vue: generic wrapper around reka-ui Select primitives
- Replace all 4 native <select> elements (font weight, effect type,
export scale, export format)
- Fix font picker dropdown truncating names (min-w-56)
- Show explanation when local fonts unavailable (Safari/Firefox)
13 tests using InMemoryTransport from @modelcontextprotocol/sdk:
- Tool registration (all 76 tools listed with descriptions)
- new_document, open_file, save_file lifecycle
- Tool execution through MCP protocol (create, fill, delete, query)
- Error paths: no document loaded, nonexistent node, invalid file path
- Full workflow: new → create → nest → query → delete
Fix @open-pencil/core dep in MCP package: workspace:* for local dev
(pnpm publish resolves this to the actual version at publish time).
Extract menu items into shared NodeContextMenuContent component,
used by both the canvas and layers panel context menus.
Right-clicking a layer selects it and shows the same menu.
Header row with app icon, double-click-to-rename document name, and
sidebar toggle button. Shows in both Tauri and browser.
When panels are hidden, a floating bar on the canvas provides the same
controls to restore the UI.

- Save reuses the filename from last Save As (no repeated prompts)
- Banner in Safari/Firefox explaining the limitation with Chrome link
- Banner is dismissible
Reka-ui Menubar in the left panel header, hidden when running in Tauri
(native menu handles it). Includes Open, Save, Save As, Export, Undo/Redo,
Zoom, Group/Ungroup, Component creation, Bring to front/Send to back,
Auto layout, Text formatting, Alignment.
- sceneNodeToJsx() in @open-pencil/core: converts SceneNode subtree to JSX
- CodePanel.vue with Prism.js highlighting, line numbers, copy button
- Third tab in properties panel: Design | Code | AI
- 14 new tests covering shapes, text, layout, effects, multi-selection
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.
- 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
The properties panel has overflow-y: auto which clips absolute
positioned popovers. Expand controls inline below the effect
row instead — simpler and always visible.
- Compact row: color swatch + type dropdown + eye toggle + minus
- Expanded controls in a floating popover anchored to the left
- Labeled rows: Position (X/Y), Blur, Spread, Color with hex + opacity
- Type dropdown in popover header with X close button
- Eye/minus icons hidden until row hover (matches fill/stroke rows)
Support adding, removing, and editing drop shadows, inner shadows,
layer blurs, background blurs, and foreground blurs. Each effect row
has visibility toggle, type dropdown, and remove button. Expanded
view shows offset, blur, spread, and color controls for shadows,
or just blur radius for blur effects.
- CanvasContextMenu now exposes onContextMenu via scoped slot instead
of wrapping in a <div> (which broke flex layout — the div had no
flex-1, so it collapsed and never received contextmenu events)
- EditorCanvas binds the handler directly on its own flex-1 div
- Fix lucide/diamonds icon not found — use lucide/component for
COMPONENT_SET (the actual 4-diamond component icon)
- FillPicker component: 3 category tabs (Solid, Gradient, Image), gradient
subtype dropdown (Linear/Radial/Angular/Diamond), draggable gradient stop
bar, per-stop color/position/opacity editing with ScrubInput
- FillSection uses FillPicker instead of ColorPicker for full Fill editing
- Default gradient transforms for each subtype so renderer picks them up
- colorToRgba255/rgba255ToColor helpers in color.ts
- Custom SVG icons for fill type tabs (solid square, gradient fade)
Document structure: Document (root) → Pages (CANVAS) → Nodes.
Each page has its own viewport (pan/zoom) and background color.
- CANVAS node type for pages
- SceneGraph: addPage(), getPages(), getAbsolutePosition stops at CANVAS
- Store: currentPageId, switchPage(), addPage(), deletePage(), renamePage()
- All operations (create, select, paste, hit test, render) scoped to current page
- Per-page viewport state saved/restored on page switch
- Pages list in LayersPanel with add/switch/double-click rename
- .fig import creates proper pages from DOCUMENT→CANVAS hierarchy
- Renderer takes pageId to render correct page's children
- Unit test for pages, updated E2E tests for page-scoped graph
When nothing is selected, the right panel shows Page section with
a color picker for the canvas background (like Figma). The page
color is stored in reactive state and passed to the renderer.
- PropertiesPanel.vue: 513 → 67 lines (composition only)
- Extracted: PositionSection, LayoutSection, AppearanceSection,
FillSection, StrokeSection, TypographySection
- Shared useNodeProps() composable for update/commit logic
- Typography panel: font family picker with search (queryLocalFonts),
weight select, font size, line height, letter spacing, text alignment
- Font picker shows each family in its own typeface
- Loads selected font into both CanvasKit and browser on pick
