Danila Poyarkov 7b011bceaf fix(fig): treat the unset override key as no key (#967 ) Figma saves layers without an override key with Kiwi's all-ones GUID, so many siblings share it. The importer stored it as a real key, and export addressed each instance layer by that key, so two such siblings got the same derived geometry address and export threw "Ambiguous instance geometry address". Instance linkage and override path matching also treated the shared value as an identity. The importer now reads the unset GUID as no key, through an isUnsetGuid helper that the cleared-style and default-slot checks share. The Preline UI kit has 1,165 such text and rounded rectangle layers; after an edit it now exports and reopens with all 104 pages.		2026-10-07 21:33:09 +00:00

README.md

@open-pencil/fig

.fig file-format package for OpenPencil.

The package owns the outer .fig archive boundary and is the staged home for Figma-specific SceneGraph conversion policy. Production SceneGraph read/write remains available through @open-pencil/core/io while conversion modules move behind this package's public API.

Current ownership:

Complete .fig archive parsing through parseFigBuffer()
.fig archive assembly through writeFigArchive()
Canvas payload and image resource handling
readFigContainer() / writeFigContainer() helpers for raw fig-kiwi payloads
.fig source and archive result types
NodeChange-to-SceneGraph property conversion, including styles, plugin metadata, text, paint, vector, and font policy, through @open-pencil/fig/node-change
Component-property, symbol-override, derived-symbol-data, and instance synchronization policy through @open-pencil/fig/instance-overrides
Effective raw-metadata precedence and invalidation over SceneGraph's format-neutral edited-field tracking
SceneGraph-to-NodeChange export conversion with an explicit text-shaping runtime service for saved glyphs
Package-local archive, conversion, instance, export, and dist smoke tests

Architecture documentation

Start with the package docs for the source model, instance evaluation, materialization, document sessions, export, and validation contracts.

Planned ownership:

Oracle-backed .fig fixtures

Non-goals:

Generic Kiwi schema/runtime internals — use @open-pencil/kiwi
Format-neutral IO registration, export targeting, CanvasKit thumbnails, or browser workers — use @open-pencil/core/io
Editor actions, renderer behavior, Vue/app UI, CLI formatting, or MCP transport

This follows the existing @open-pencil/pen pattern: a format package owns its source model/parser and SceneGraph policy, while core registers it in the shared IO system.
