Text nodes with textAutoResize=WIDTH_AND_HEIGHT kept their 100×100
default SceneNode size when MeasureFunc was unavailable (no CanvasKit),
blowing up every HUG container.
Add fallback estimator (~0.6 × fontSize per char) in layout.ts so
headless layout produces sane sizes.
DO NOT change textAutoResize defaults in renderer.ts without testing
headless layout — see comments there and in layout.ts.
* Fix auto-layout overflow: MeasureFunc, min/max, absolute positioning, text wrap
Layout engine (layout.ts):
- Use Yoga MeasureFunc for text nodes instead of static pre-measurement,
so text wraps correctly when width is determined by flex layout
- Add min/max width/height constraint support (minWidth, maxWidth, etc.)
- Translate counterAxisAlignContent to Yoga setAlignContent for wrap layouts
- Extract configureFlexContainer to share between root and nested frames
JSX renderer (render/renderer.ts):
- Auto-set layoutPositioning ABSOLUTE for elements with x/y inside auto-layout
- Fix text auto-resize: set HEIGHT when text fills parent in auto-layout
Text measurer (renderer/renderer.ts):
- Accept optional maxWidth parameter for constraint-based measurement
* AI prompt: prefer describe over export_image for post-render verification
* Strip TS casts from AI-generated JSX before sucrase parse
AI models sometimes emit `as any`, `as const` etc. in JSX props.
Sucrase with jsx-only transform can't handle these, causing parse errors.
- Strip TypeScript cast expressions before passing to sucrase
- Add forbidden patterns to AI prompt: as any, template literals for
sizes, Math.random()
* Cache text MeasureFunc results to avoid repeated buildParagraph calls
Yoga calls MeasureFunc multiple times per node during calculateLayout.
Each call was creating a full CanvasKit Paragraph — expensive for layouts
with many text nodes. Cache by rounded constraint width.
* AI chat: fix provider settings popover, add max output tokens, fix paste in chat input
- Fix ProviderSettings popover not visible (remove tooltip/popover trigger
conflict, add collision-padding, isolate z-[51])
- Add configurable max output tokens (default 16384) in provider settings
- Pass maxOutputTokens to ToolLoopAgent to prevent truncated tool calls
- Add system prompt size limits: split render calls at ~40 elements
- Fix paste/copy/cut in chat input (stop event propagation to canvas handler)
* Fix 6 layout engine bugs: hidden size, FILL basis, SPACE_EVENLY, alignSelf range, grid stretch, absolute children
Layout engine (layout.ts):
- Guard applyYogaLayout to preserve hidden children dimensions
- Add setFlexBasis(0) for FILL sizing so children share space from zero
- Add SPACE_EVENLY to mapJustify via Justify.SpaceEvenly
- Replace hardcoded STRETCH checks with mapAlignSelf for full range
- Use setWidthStretch/setHeightStretch for grid children instead of flexGrow
- Insert absolute children in Yoga tree via configureAbsoluteChild with
PositionType.Absolute, keeping manual x/y (no write-back)
Types (scene-graph.ts):
- Add SPACE_EVENLY to LayoutAlign union
- New LayoutAlignSelf type: AUTO | MIN | CENTER | MAX | STRETCH | BASELINE
Import (kiwi-convert.ts):
- Map SPACE_EVENLY correctly instead of collapsing to SPACE_BETWEEN
- New mapAlignSelf function for full StackCounterAlign range
Tools (modify.ts):
- Expand set_layout align enum with SPACE_EVENLY
- Expand set_layout_child align_self enum with MIN/CENTER/MAX/BASELINE
Tests: 86 pass (+13 new covering all 6 fixes)
* Grid layout support in JSX renderer, auto-height grids, flex children stretch in cells
Renderer:
- Parse grid/columns/rows/columnGap/rowGap/gap props
- Parse grid child positioning: colStart/col/rowStart/row/colSpan/rowSpan
- Grid prop takes precedence over padding-triggered auto-layout
- SPACE_EVENLY added to ALIGN_MAP
- Numeric columns shorthand (columns={3} → 3×1fr)
- Auto-height: grid without rows sets height=0 for Yoga auto-sizing
- fill sizing in grid children → layoutAlignSelf: STRETCH
- Component builders accept variadic children: Frame(props, ...children)
Layout:
- Grid auto-height: skip setHeight when no gridTemplateRows
- Write back computed height for auto-height grids
- Grid children with layoutMode stretch width to fill cell
- recomputeGridChild: re-run flex layout after grid assigns cell size
(temporarily sets sizing to FIXED so HUG doesn't override grid width)
Export:
- Skip height export for auto-height grids (no rows template)
Tests: 18 new grid render tests covering all paths
* Auto-enable flex for justify/items props, discourage export_image in AI prompt
* Address review: use sucrase typescript transform, don't reset chat on maxOutputTokens change
* Fix lint errors: extract applyFrameSize, wrap nested ternary, remove unnecessary cast
* Remove SPACE_EVENLY — not a valid Figma layout value
* CI: debug LFS pull from R2
* Apply maxOutputTokens dynamically via prepareCall instead of at agent creation
* Fix heavy .fig parse: restore GUID/defID guards, fix optional types
Commit f3eac5a removed null guards from fig-import and
instance-overrides as 'unnecessary conditions', but Kiwi-decoded data
can have NodeChanges without GUIDs and ComponentPropAssignments/Refs
without defIDs. Made the types optional to match reality.
Also fix CI LFS: add git lfs install --force before pull (R2 endpoint
needs the filter registered first).
* Fix Google AI model IDs: gemini-3.1-pro → gemini-3.1-pro-preview

- Move svg-export-{defs,paths}.ts into svg-export/ folder
(defs.ts, paths.ts, index.ts) instead of prefix-based split
- Remove duplicate getChildren lambda in fig-import.ts importPages
- Remove dead dashPattern local in kiwi-convert.ts nodeChangeToProps
- Restore useful explanatory comments in instance-overrides.ts
(DSD propagation, direct vs cloned assignments, seed skipping)
- Rename applyEffectOverrides → applyShapeAndEffectOverrides
(handles polygon props + shadow + blur, not just effects)
- Format src/ with oxfmt
* 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
The render tool needs esbuild to transform JSX, but esbuild only runs in
Node — not in the browser where the automation server executes. The bridge
now intercepts render tool calls, converts JSX to a tree on the Node side
using buildComponent + resolveToTree from core, and sends the tree to the
browser which calls renderTreeNode directly.
Also exports createElement and resolveToTree from core for bridge use.

- Use satisfies instead of as for handle position map
- Type node() to accept { children?: unknown; [key: string]: unknown }
- Remove ext() helper in kiwi-convert (direct property access)
37 occurrences → 1 (Kiwi codec boundary only).
Replace all 'Inter' string literals with DEFAULT_FONT_FAMILY from
constants. Add loadFontsForNodes() that collects font families from
text nodes and loads them into CanvasKit, called after clipboard
paste and .fig file import.
Replace 8 inline { r: 0, g: 0, b: 0, a: 1 } literals across core
with shared constants from constants.ts. Also reuse CANVAS_BG_COLOR
in fig-export.ts instead of duplicating the value.
