Changelog

Unreleased

Changed

  • Add JSX authoring support for components, component sets, and instances.

Fixes

  • Fix tooltips around inspector dropdowns/popovers without breaking floating menu anchoring.
  • Harden MCP calls with bounded page-tree responses, oversized-result errors, JSON HTTP responses, and stale WebSocket cleanup.
  • Improve Figma boolean imports by preserving XOR operations as editable exclude nodes and falling back to imported fill geometry when boolean path reconstruction cannot produce a path.
  • Preserve rotated Figma transform origins for imported vector nodes.
  • Render complex text fills through vector glyph outlines so imported Figma text can use the normal fill pipeline for gradients, images, patterns, and other non-solid paints.

0.13.2 — 2026-05-30

Changed

  • Update the Homebrew install command to use the published openpencil cask.

Fixes

  • Fix the published MCP package so global installs include the openpencil-mcp and openpencil-mcp-http launchers required by desktop app integrations.

0.13.1 — 2026-05-29

Fixes

  • Fix the npm package contents for the CLI so Bun installs include the built openpencil binary and runtime bundle.

0.13.0 — 2026-05-29

Fixes

  • Fix the published CLI package so Bun global installs run the built openpencil binary instead of raw TypeScript sources.

  • Greatly improve importing Figma .fig files with complex component systems: badges, avatars, icons, links, input fields, lists, date pickers, nested instances, component swaps, and variant properties now open much closer to their original Figma appearance.

  • Fix missing or white content in imported .fig files caused by unresolved Figma variable bindings, including image/avatar badges, icon colors, text colors, and variable-backed component overrides.

  • Preserve more Figma document details when opening and saving .fig files, including internal component pages, component ordering, page metadata, canvas backgrounds, text layout, glyph rendering, vector geometry, effects, shadows, and instance overrides.

  • Keep user edits after opening an imported .fig file: changing size, position, fills, text, or layout now wins over preserved Figma round-trip data when the document is saved again.

  • Fix .fig exports so files reopened in Figma or OpenPencil keep their pages, components, instances, text wrapping, icons, avatars, and preview thumbnail intact.

  • Fix live canvas updates during move/resize/edit previews so visible scene changes repaint immediately.

  • Fix accidental duplicate creation when Alt-clicking without dragging.

  • Fix MCP startup in the browser.

  • Fix CanvasKit loading outside the browser when project paths contain spaces.

  • Render imported Figma layer and fill blend modes such as multiply, screen, overlay, difference, hue, saturation, color, and luminosity.

  • Render common imported Figma mask stacks so visible layers above alpha, vector, or luminance masks are clipped by the mask shape, including consecutive mask layers.

  • Render Figma-style smoothed rectangle corners, including independent corner radii, and effect blend modes from imported Figma files.

  • Improve imported tiled image fills by applying Figma image transforms when repeating image patterns.

  • Keep imported Figma boolean operations editable as boolean-operation nodes instead of flattening them to vectors.

  • Apply imported variable font axes from Figma fontVariations when rendering text.

  • Render more imported Figma visual metadata, including text decoration styles, leading trim, pattern fills, layout grids, page guides, and deterministic fallbacks for raw noise effects.

Performance

  • Open large .fig files faster by deferring work for pages you have not viewed yet while still preparing all needed content before export.
  • Improve canvas responsiveness during zooming, panning, dragging, and editing by reusing cached scene backing where safe.
  • Speed up .fig export for documents with many preserved Figma paint and variable payloads.

0.12.2 — 2026-05-19

Added

  • Allow OpenRouter users to enter any model ID from provider settings with cached autocomplete suggestions for tool-capable models, while keeping the curated dropdown as the default when no custom model is set.

Changed

  • Use localized app tooltips instead of native browser titles across editor controls, panels, and menus.
  • Update Claude Code MCP setup documentation and the docs landing screenshot.
  • Ignore non-source Markdown files in the app dev watcher so documentation edits do not reload the running editor.

Fixes

  • Route Claude Code stdio MCP requests through the live OpenPencil app connection, including immediate disconnected errors when no document is connected.
  • Keep MCP disconnected guidance focused on starting OpenPencil and opening a document.
  • Improve agent-rendered JSX compatibility with Figma-style text, alignment, and rotation aliases; strip HTML comments; and report unsupported props from render tools.
  • Load exact text font styles after MCP and AI tool mutations so newly created bold/weighted text renders immediately.
  • Include text style fields in MCP get_node output so agents can verify generated text accurately.
  • Keep provider settings tooltip/popover composition working in WebKit.

0.12.1 — 2026-05-19

Fixes

  • Fix .fig round-trips for OpenPencil component sets and variable bindings, and recompute imported layouts after opening documents.
  • Report desktop/MCP package version mismatches explicitly and include package-manager-aware install guidance from the MCP server.
  • Support scoped MCP save_file({ path }) workflows while keeping file saving in the desktop app.
  • Use native Tauri path handling for save parent directories so Unicode and Windows paths are handled correctly.
  • Fix the web font picker so Google Fonts remain available in Safari, local font access is requested on first open when supported, font sources are labeled, and Google font previews load lazily for visible rows.
  • Fix background blur rendering so it blurs the backdrop behind a layer instead of applying a no-op content filter, and keep effect parameter controls visible in the properties panel.

0.12.0 — 2026-05-18

Added

  • Assets panel — browse, search, and insert document components directly from the left sidebar.
  • Component variants — switch instance variants from the right inspector; default variant respects property definitions.
  • Figma library metadata — component keys, source libraries, version IDs, descriptions, and docs links are preserved on import/export.
  • Desktop file associations — double-click .fig or .pen files in Finder/Explorer to open them in OpenPencil.
  • Auto-update — startup update checks and a Check for Updates menu item on desktop.
  • Light theme with theme-aware canvas rulers.
  • PDF export — available in the export panel, CLI (--format pdf), and MCP.
  • SVG import tool for automation workflows.
  • DeepSeek AI provider.
  • Variable modes — create, rename, duplicate, delete, and set defaults per collection.
  • Variable binding controls for fills, strokes, sizing, min/max, and typography fields.
  • Auto-layout inspector controls for min/max dimensions, auto gap, wrap gap, and two-axis padding.
  • Stroke dash/gap controls.
  • Font settings — local font access, fallback predownloads, and downloaded font cache management.
  • Editor commands for frame selection, paste to replace, Boolean operations, flatten, outline text, and outline stroke.
  • Boolean operations panel control and canvas context-menu entries for flattening and outlining supported selections.

Changed

  • Smaller domain modules across core, app, Vue SDK, CLI, MCP, docs, and desktop with enforced package boundaries.
  • Separate scene and overlay canvas layers — rulers, labels, and selections no longer cause scene redraws.
  • Shared menu schema between browser and native Tauri menus.
  • Editor command metadata now drives shortcut display across browser menus, native menus, tooltips, and context menus.
  • Text-to-vector conversion now uses shared loaded-font outline geometry across Boolean, flatten, and outline commands.

Fixes

  • Fix .fig export of component variant properties and text stretch alignment so designs round-trip correctly through Figma.
  • Fix CJK and Arabic text rendering — fallback fonts now load before the first paint instead of showing blank text.
  • Fix large .fig files freezing on open — parsing runs in a worker, and the viewport fits to content after loading.
  • Improve Figma import fidelity — variable aliases, nested instances, avatar swaps, badge internals, and input text alignment are preserved.
  • Improve Figma export fidelity — flipped vectors, stroke geometry, visual overflow, and stroked-shape drop shadows are preserved.
  • Fix variant switching so instances update their contents, not just the component reference.
  • Fix text editing inside components and instances on double-click.
  • Fix paste into selected containers and entered frames.
  • Fix clipboard parsing to safely ignore invalid data.
  • Fix undo/redo for duplicate, state restore, and modifier-key release.

  • Fix canvas size badges scaling with zoom.
  • Fix layout inspector dropdown anchoring and spacing/padding icon clarity.
  • Fix section drawing and color input forwarding in the property panel.
  • Fix asset insertion coordinates inside entered containers.
  • Fix MCP stdio handshake and eval return values.
  • Fix @open-pencil/vue npm imports referencing an unexported core subpath.
  • Fix Figma clipboard text compatibility — pasted OpenPencil text keeps editable fixed bounds, line wrapping, baselines, glyph offsets, and Figma edit-mode layout.
  • Fix local font matching so requested upright and weighted faces do not fall back to italic or regular faces.
  • Fix CanvasKit paragraph rendering to preserve requested text weights and slants.
  • Fix nested text editing interactions — drill double-click enters nested text edit mode, and clicking another text node switches edit targets while editing.
  • Fix auto-height text edit commits so text bounds and undo state stay in sync.
  • Fix Boolean, flatten, and outline operations to reject unsupported image/complex-script sources safely instead of silently dropping geometry.
  • Fix outline stroke enablement for stroked descendants inside groups and containers.

Performance

  • Event-driven canvas rendering — scene and overlay layers only repaint when their inputs change, replacing continuous polling.
  • Shared RAF scheduler coalesces scene and overlay frames into a single animation frame per editor.
  • Font-family fallback arrays and downloaded remote fonts are cached to avoid repeated work.
  • WebGL draw-call instrumentation only runs while the profiler is active.
  • Instance override resolution is cached and .fig pages load lazily for large files.
  • Live drag/resize uses repaint-only previews to skip layout during interaction.

  • Resume pen drawing from existing open path endpoints — click an endpoint to continue the curve
  • Close open paths by dragging one endpoint to the other
  • Align selected anchor points relative to each other in vector edit mode — the standard alignment buttons in the position panel now operate on selected vertices when 2 or more are selected
  • Unified core IO format registry — .fig is now modeled as the native document format alongside shared export adapters for PNG, JPG, WEBP, SVG, and JSX
  • Export selection or current page as .fig from the app export UI and app menu

  • Fix imported .fig file open and page-switch regressions — loaded documents now keep graph/store state in sync, remap imported canvas/page children correctly, and recompute imported auto-layout descendants when switching pages
  • Fix first canvas render happening before fonts load — wait for fonts before the initial draw to avoid Safari and text measurement glitches
  • Preserve fig-kiwi version on .fig roundtrip — imports keep the original header version instead of rewriting everything to a hardcoded value; new files default to version 101

  • Fix browser/headless rendering mismatch for imported toolbar/instance content by correcting runtime imported layout recomputation instead of diverging browser rendering behavior
  • Fix set_layout tool not defaulting to HUG sizing when enabling auto-layout — frames now shrink/grow to fit children instead of keeping fixed dimensions
  • Normalize font family names on .fig export — strip optical size suffixes (e.g. "DM Sans 9pt" → "DM Sans") so Figma recognizes the font
  • TEXT nodes now default to a solid black fill — previously exported with no fill, making text invisible when opened in Figma
  • Fix save crash when COLOR variable is missing alpha channel
  • Fix console error spam on deployed web app from automation WebSocket reconnect loop

  • Dev-only debug toolbar for copying chat logs
  • Auto-layout icons in layer tree — vertical (rows), horizontal (columns), and grid icons for auto-layout frames; components keep their purple diamond
  • Frame titles on canvas are now draggable — clicking a selected top-level frame's name label starts a drag
  • Compact layout controls — icon-based gap (↔/↕) and padding (T/R/B/L) inputs instead of text labels

  • CLI-to-app RPC bridge — all CLI commands work against the running app when no file is specified. Start the app, then run bun open-pencil tree to inspect the live document
  • VitePress docs site — user guide, reference, architecture, and development docs at openpencil.dev with 6 locales (en, de, fr, es, it, pl), SEO (OG tags, hreflang, JSON-LD, sitemap), and dark theme

Improvements

  • Refactor mobile drawer tabs, layout sizing dropdowns, and inline rename to use Reka UI primitives
  • Add shared UI style helpers with tailwind-variants for menus, selects, buttons, and surfaces

  • Add geometry.ts with shared rotation math (degToRad, radToDeg, rotatePoint, rotatedCorners, rotatedBBox)
  • Extract isArrayMixed() helper for multi-selection property panels

Fixes

  • Fix ALL_TOOLS registry missing newer tools (analyzeColors, diffCreate, exportImage, arrangeNodes)
  • Fix renderJSX typo in tool definitions (renderJsx → renderJSX)
  • Fix all oxlint warnings and tsgo errors — replace ! non-null assertions in use-collab.ts with local const captures
  • Fix broken test imports — stale ../../src/engine/ paths updated to @open-pencil/core
  • Fix flaky E2E tests: layers panel navigates to /demo, zoom-to-fit test zooms in first, snapshot rendering stabilized with workers: 1 and colorScheme: dark

  • Renderer profiler with in-canvas HUD overlay, GPU timing, and phase instrumentation

Improvements

  • Replace custom color picker with Reka UI Color components (ColorArea, ColorSlider, ColorField) — adds keyboard navigation and accessibility to the color area, hue, and alpha controls

Fixes

  • CJK text rendering — load a system CJK font (PingFang SC, Microsoft YaHei, Noto Sans CJK) as fallback; falls back to Noto Sans SC from Google Fonts when no system font is available (#48)
  • Font registration errors no longer cache invalid font data — loadFont only caches after successful CanvasKit registration
  • Fix render tool failing on Windows + Bun with "Cannot find module" error (#43)
  • Fix hover highlighting nodes from internal component pages — scope hit-test to current page
  • Fix hit-testing on transparent frames and groups — empty containers without fills or strokes are now click-through, clipping parents reject hits outside their bounds, matching Figma behavior
  • Fix instance overrides on .fig import and clipboard paste — resolve guidPaths by overrideKey, handle component swaps (overriddenSymbolID), propagate through nested clone chains. Import and paste now share a single override engine.
  • Apply Figma component property assignments on import — boolean visibility toggles and instance swaps via componentPropRefs/componentPropAssignments
  • Apply derivedSymbolData sizes on import — containers now shrink correctly when component properties hide children
  • Fix override resolution for nested instance targets — check the current node before searching descendants
  • Fix component property assignments for nested instances — resolve scoped componentPropAssignments inside symbolOverrides via guidPath, handle guidValue for instance swaps, reorder phases so transitive sync doesn't clobber visibility
  • Pixel-perfect vector rendering using pre-computed fillGeometry/strokeGeometry blobs from .fig files — eliminates white gaps between adjacent stroked shapes
  • Stroke outlines on clipboard paste — convert vectorNetwork paths to filled outlines via CanvasKit when geometry blobs are unavailable
  • Apply derivedSymbolData transforms and geometry during import — instance children render at correct scale and position
  • Fix internal pages becoming visible after .fig round-trip — preserve internalOnly flag on export
  • Scope layout recomputation to current page for paste/undo/font-load (major speedup on large multi-page files)
  • Show loading overlay until all document fonts are loaded (no more partially rendered text)
  • Load fonts when switching pages (previously only loaded for the first page)
  • Always show visibility toggle on fill, stroke, and effect rows (matches Figma)
  • Fix renderer crash on double destroy when closing files quickly
  • Fix .fig page ordering — use deterministic byte comparison for fractional index positions
  • Fix text truncation using textTruncation field instead of textAutoResize
  • Fix horizontal scrollbar on design and pages panels
  • Style scrollbars for Tauri (thin dark overlay instead of default OS chrome)
  • Enable file watcher in Tauri — watch feature was missing from tauri-plugin-fs

  • Fix vector rendering on paste — scale path coordinates from Figma's normalizedSize to actual node bounds
  • Fix pasted instances having no children — populate from component via symbolData when both are in clipboard
  • Detect component sets on import — promote FRAME nodes with VARIANT componentPropDefs to COMPONENT_SET
  • Skip internal canvas on paste — components on Figma's hidden internal page populate instances but are not pasted as visible nodes
  • Apply instance overrides on paste — text content, fills, visibility, layoutGrow, and textAutoResize from symbolOverrides
  • Fix auto-layout child ordering — sort by geometric position instead of z-order position strings
  • Load fonts on paste and .fig import — collect font families from text nodes and load into CanvasKit
  • Text measurement in auto-layout — use CanvasKit paragraph metrics for WIDTH_AND_HEIGHT text nodes
  • Recompute layouts after font loading completes
  • Fix PERCENT line height conversion — was stored as raw value instead of pixels
  • Fix InvalidCharacterError when copying nodes with non-ASCII text
  • Load all font weight/style variants needed by pasted text nodes
  • Fix font loading not registering in core cache
  • Fix halfLeading applied to text measurement — enable only for rendering
  • Clear hover on zoom/pinch to keep scene picture cache valid
  • Fix flip buttons using rotation math instead of actual mirroring
  • Fix flip transform encoding — scale first matrix column only (was incorrectly producing 180° rotation)
  • Decode flip state from .fig transform matrix on import

0.5.1 — 2026-03-03

  • Fix active tab text invisible against same-color background
  • Fix clipboard "Outside int range" error — pasteID used unsigned int exceeding Kiwi's signed 32-bit field
  • Error toasts are now sticky (don't auto-dismiss), with selectable text, copy button, and close button
  • Truncate long node names in export button

Performance

  • Per-node SkPicture cache for effect rendering — unchanged shadow/blur nodes replay from cache on scene redraws

  • Cached ImageFilter, MaskFilter, reusable effect paint — zero per-frame WASM allocations for effects
  • Reuse GL context on panel resize — swap surface without recreating renderer, preserving all caches
  • Per-frame absolute position cache — avoids repeated parent-chain walks during rendering
  • Optimize zoom/pan smoothness with shallowReactive, useRafFn, and input coalescing

Build

[0.4.2] (2026-03-02)

Fixes

  • Fix Figma clipboard paste: skip non-visual node types (variables, widgets, stickies, connectors)
